Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle parking lock device used in a bicycle parking system that controls the parking management by locking or unlocking the wheels of a two-wheeled vehicle, especially a bicycle in an unmanned management state.

  In recent years, large bicycle parking facilities are often installed in the vicinity of railway stations, but a large number of bicycles cannot be accommodated, and it has become impossible to provide bicycle parking facilities to all those who wish to use the bicycles.

  Therefore, a mode in which a large number of bicycle parking lock devices are consecutively installed along the street without any special location and used by users appropriately has become widespread. Is basically in an unmanned management state, and in general, it is generally in a management state in which a person in charge of management patrolls by illegally parking bicycles.

  Conventionally, in such a bicycle parking lock device that is installed based on unmanned management, a bicycle parked in the bicycle parking lock device is pushed into the rack, and when the bicycle is pushed all the way in, the locking device is locked. Different forms were adopted. However, in the bicycle parking device in which the bicycle is pushed into the lock device in this way, the user does not push the bicycle to the back and leaves the bicycle stationary in the middle of the rack, so-called sized parking bicycle is widespread and appropriate. There were many illegal users who left without paying the fee.

  Therefore, in recent years, a mode has been adopted in which the lock arm advances from the lower side of the rack to hold the tire of the bicycle simply by placing the bicycle on the rack and without pushing it into the back of the rack.

  For example, in Patent Document 1, when an outer frame having an horseshoe-shaped cross section opened upward is provided with a protective frame also having a longitudinal cross section and formed in an inverted gate shape at approximately the center of the outer frame, the wheel is mounted on a bicycle. A guide frame whose one end is rotated by the load of, and a part of the wheel is held vertically from the left and right direction by the load generated by the rotation of the guide frame in the substantially central width direction of the guide frame. A bicycle-parking device is disclosed in which a bicycle is locked by a pair of movable arms that open and close.

  Further, Patent Document 2 discloses a bicycle parking device in which a locking member advances and retracts from only one side of a wheel mounting base, and Patent Document 3 further includes a guide wheel at a tip of a holding claw portion of a movable arm. A locking device is disclosed.

  Since these bicycle parking devices are installed in a street where a user using the bicycle parking device and general pedestrians coexist, the bicycle parking device is not used in the immediate vicinity of the bicycle parking device. Passersby can come and go without any restrictions. At that time, not only adults but also children and infants cannot be strictly regulated so as not to enter the vicinity of the bicycle parking device. In such a situation, an infant may mischief the bicycle-parking device or get in the vicinity of the device. In such a case, no conventional bicycle-parking device has taken any safety measures. It was

  For example, in the bicycle parking apparatus of Patent Document 1, when a guide frame is accidentally stepped on by a passerby or the like, particularly an infant, the legs are caught by a pair of movable arms, and there is no risk of injury. Can not.

  Also in the locking device of Patent Document 2, the lower pressing portion of the locking member can be easily stepped on, and there is a risk of injury to the leg due to the locking member penetrating the entire width of both guide rods.

  Further, in Patent Document 3, although a guide wheel for protecting the bicycle tire and rim from being damaged is attached to the tip of the holding claw portion of the movable arm, if the legs are sandwiched by both guide wheels, the same is true. May be injured.

  As described above, the conventional bicycle parking lock device has a problem in that it is not possible to eliminate the risk of entering such an infant when a large number of devices are installed on the shoulders of a busy street in an unmanned management state.

  In view of the above circumstances, an object of the present invention is to provide a bicycle parking lock device capable of eliminating as much as possible a danger when a passer-by other than a bicycle, especially an infant, accidentally steps on a wheel guide portion or the like. Especially.

In order to achieve the above object, a bicycle parking lock device according to an aspect of the present invention includes a guide frame body, a wheel guide mechanism, and an arm moving mechanism.
The guide frame body has a first end portion into which a wheel of a motorcycle can enter, a second end portion that faces the first end portion in a first axial direction, and is orthogonal to the first axial direction. And a pair of guide plates that face each other at a first interval in the second axial direction and that guide the movement of the wheels from the first end portion to the second end portion.
The wheel guide mechanism includes a wheel guide arranged inside the guide frame, on which wheels are placed, and a guide support shaft that tiltably supports the wheel guide around an axis parallel to the second axis. The wheel guide is configured to be tiltable around the guide shaft from the non-parked position to the parked position by the weight received from the wheel.
The arm moving mechanism includes a pair of lock arms arranged on the pair of guide plates, and a pair of arm support shafts for rotatably supporting the pair of lock arms around an axis parallel to the first axial direction. Have and. The pair of lock arms support the wheel guide and rotate the pair of lock arms around the pair of arm support shafts when the wheel guide is tilted. It has a pair of hooks that project inward from the outside of the pair of guide plates by rotation. The pair of hooks are spaced apart from each other at a second distance in the first axial direction.

  The second interval may have a size equal to or larger than that of the first interval.

  The first interval may be 55 mm or more and 65 mm or less.

  Each of the pair of lock arms may be formed of a metal plate, and each of the pair of hooks is formed of a folded portion in which the metal plate is folded back in the first axial direction in opposite directions. Good.

  The pair of lock arms may each have a through-hole portion through which the pair of arm support shafts penetrate, and the through-hole portion is the first axial direction of the pair of hook portions with respect to the guide frame body. It may have a shape that allows relative movement to.

  The guide frame body may further include a pair of recesses or notches provided on the pair of guide plates and facing each other in the second axial direction and the pair of hooks.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<First Embodiment>
FIG. 1 is an external view of a bicycle parking system according to an embodiment of the present invention. The overall configuration of the bicycle parking system 100 of this embodiment will be described below.

[Overall configuration of bicycle parking system]
The bicycle parking system 100 includes a bicycle parking area PA installed between a sidewalk Sw and a road St of a street, a plurality of bicycle parking lock devices 1 installed in the bicycle parking area PA, and one end of the bicycle parking area PA. And a settlement machine 6 installed in the.

  The bicycle parking area PA is installed on the sidewalk Sw. The sidewalk Sw is slightly higher than the roadway St, and the bicycle parking area PA is often installed on the side of the roadway St of the raised sidewalk Sw. Although a guardrail or the like (not shown) is installed between the road St and the sidewalk Sw, no barrier or the like is installed between the bicycle parking area PA and the sidewalk Sw, which particularly prevents traffic. However, in order to distinguish the bicycle parking area PA and the vehicle driving lane from the sidewalk Sw, the ground of the bicycle parking area PA is painted differently from the ground of the sidewalk Sw, or a bicycle mark (not shown) is drawn. I often do it.

  In the bicycle parking area PA, a base PB that is slightly elevated above the ground is installed in a long shape along the street. The base PB is a gate type and is composed of a hollow metal frame body. The base PB is previously separated into a long length for every fixed length (for example, for 6 bicycle parking lock devices), and by connecting in the longitudinal direction in the street where it is installed, a large number of bicycle parking locks are provided. The device 1 is installed. Further, electric wiring (not shown) is provided inside the base PB to electrically connect the checkout machine 6 and each bicycle parking lock device 1. Wiring, piping, etc. are not exposed outside the base PB so that pedestrians and users of the bicycle parking system 100 do not stumble on the wiring.

  A large number of bicycle parking lock devices 1 are arranged in parallel on the upper surface of the base PB. The large number of bicycle parking lock devices 1 includes a large number of bicycle parking lock devices 1H at a high position and a large number of bicycle parking lock devices 1L at a low position, and the handles of the bicycles Bc parked at the adjacent bicycle parking lock devices 1 are connected to each other. The two types of bicycle parking lock devices 1 (1H, 1L) are alternately arranged along the street so that they do not come into contact with each other. In the example of FIG. 1, the bicycle parking lock device 1 on the most adjustment machine 6 side is the bicycle parking lock device 1H at the high position, and the left next door is the bicycle parking lock device 1L at the low position. The bicycle parking lock device 1H and the low bicycle parking lock device 1L are alternately arranged, but for simplicity, only two bicycle parking lock devices 1H and 1L are shown.

  The user parks the bicycle Bc by inserting the wheel W (in most cases, the front wheel) into the bicycle parking lock device 1 from the sidewalk Sw side, but in the following description, the inserting direction of the bicycle Bc is the front-back direction. The description will be made by defining the directions of up, down, left and right as viewed in the direction. Further, the high-position bicycle parking lock device 1H and the low-position bicycle parking lock device 1L are collectively referred to as the bicycle parking lock device 1 unless individually described.

  The settlement machine 6 is configured to control a large number of bicycle parking lock devices 1 at a time, and performs a settlement process for a large number of bicycle parking lock devices 1. In addition, the control of another block across the traffic light etc. of the street is performed by arranging other settlement machines, and one parking lot has many parking lock devices along the street of one block (block). Is configured to control.

  A unique serial number is assigned to each bicycle parking lock device 1 and is visually displayed on the appearance of the bicycle parking lock device 1. In the example of FIG. 1, the numbers “1”, “2”,... Are assigned from the bicycle parking lock device 1 closest to the settlement machine 6. The user is required to enter the serial number into the settlement machine 6 and then settle the fare in order to change the locked state of the bicycle parking lock device 1 parked with his/her bicycle Bc from the locked state to the unlocked state.

  The settlement machine 6 is arranged so that the display screen device 601 and the charge storage operation unit (operation key group) 602 face the sidewalk Sw side. Further, as described above, a large number of electric wirings are wired from the lower part of the settlement machine 6 to each bicycle parking lock device 1 through the inside of the base PB. The configuration and operation of the settlement machine 6 will be described later.

  The location where the bicycle parking system 100 is installed is not limited to the street, and may be installed inside the bicycle parking lot where the manager is resident.

[Bicycle parking lock device]
Next, the configuration of the bicycle parking lock device 1 will be described.

(Basic configuration)
2A and 2B are partially transparent side views showing the internal structure of the bicycle parking lock device 1 when viewed from the left side. The bicycle parking lock device 1H in a high position (FIG. 2A) and the bicycle parking lock device in a low position are shown. The cross section at the center in the left-right direction of the guide frame body 10 in each 1L (FIG. 2B) is shown.

  The bicycle parking lock device 1 includes a guide frame body 10, a wheel guide mechanism 20, an arm moving mechanism 30, and a lock mechanism 40. The guide frame 10, the wheel guide mechanism 20, the arm moving mechanism 30, and the lock mechanism 40 form a main body 50 of the bicycle parking lock device 1.

  In the high position parking lock device 1H shown in FIG. 2A, the main body 50 is installed on the base PB at a position separated from the base PB by the front and rear pillars C1 and C2. Between the rear end 11 of the guide frame 10 and the ground of the bicycle parking area PA, a channel-shaped slope F having an open U-shaped cross section is attached. Although not shown, the pillars C1 and C2 are quadrangular pillars having a hollow inside as a whole, and electric wiring is provided inside the base PB through the inside of the pillar C1 on the front side.

  In the low position bicycle parking lock device 1L of FIG. 2B, the main body portion 50 including the guide frame body 10 is attached to the upper surface of the base PB.

  As described above, the bicycle parking lock device 1H in the high position and the bicycle parking lock device 1L in the low position have the same configuration in the main body portion 50 itself, and the operation of the bicycle when parking the bicycle is performed along the slope F. The only difference is whether W is inserted into the guide frame body 10 after being raised or directly inserted into the guide frame body 10. Therefore, in the following description, only the relative relationship between the main body 50 of the bicycle parking lock device 1 and the wheels W of the bicycle will be described in the description of the configuration and operation of the bicycle parking lock device 1.

  Next, details of the configuration of the main body portion 50 of the bicycle parking lock device 1 will be described.

  3A to 3C are a top view, a left sectional view and a rear view of the main body 50 of the bicycle parking lock device 1, respectively. 4A and 4B are partially transparent perspective views showing the internal structure of the main body part of the bicycle parking lock device 1, where A shows a non-parked state (state before wheel mounting or wheel detached state), and B shows , Shows the parking state (wheel mounting state or wheel accommodation state). In FIGS. 4A and 4B, the left and right guide plates are shown in a transparent manner in order to facilitate understanding of the internal state.

(Guide frame)
The guide frame body 10 has a rear end portion 11 (first end portion), a front end portion 12 (second end portion), and a pair of guide plates 13L and 13R.

  The rear end portion 11 has an entrance 11h into which a wheel W of a bicycle Bc (two-wheeled vehicle) can enter. The front end portion 12 faces the rear end portion 11 in the front-rear direction (first axial direction), and is configured as a closed end portion in the present embodiment. The pair of guide plates 13L and 13R face each other with a space D1 (first space) in the left-right direction (second axial direction), and the wheels W that have entered the rear end portion 11 are fed from both left and right sides in the traveling direction. While supporting, the movement of the wheel W from the rear end portion 11 to the front end portion 12 can be guided.

  The guide frame body 10 is typically made of a metal material and has a shape in which approximately two left and right flat plates (guide plates 13L and 13R) are connected by a bottom plate and a front plate. A rear guide shaft 14 is fixed at a position close to the rear end portion 11, and a front guide shaft 15 is fixed above the front end portion 12 between the left and right guide plates 13L and 13R, respectively.

  The pair of guide plates 13L and 13R have a substantially symmetrical outer shape, and have a height that allows the wheels W housed in the guide frame body 10 to be maintained in a substantially vertical posture. In the present embodiment, the upper edge portions of the guide plates 13L and 13R are formed at a constant height from the rear end portion 11 to the front end portion 12, are inclined obliquely upward from the middle, and further reach the rear end portion 12. Is formed with a constant height up to. The upper end corners of the entrance 11h and the upper edges of the guide plates 13L and 13R are bent outward so that the wheels W can easily enter.

  Since the left and right guide plates 13L and 13R guide and hold the wheels W of the bicycle, the left and right guide plates 13L and 13R are slightly wider than the wheels W and are erected parallel to each other. The internal width (distance D1) between the guide plates 13L and 13R is determined in view of the structure around the tire including the rims and spokes of the wheel W, and the tire width (about 50 mm) of the mountain bikes that have already been widely used, For example, the size is set to 55 mm or more and 65 mm or less, and is about 60 mm in this embodiment.

  In addition, trail bicycles and moped motorcycles, which are called fat bikes and have wide tires of about 4 inches (100 mm or more), may not be applicable, or a dedicated main body part capable of parking them may be excluded. The provided bicycle parking lock device may be separately installed.

(Wheel guide mechanism)
The wheel guide mechanism 20 includes a wheel guide 21 and a guide support shaft 22 that tiltably supports the wheel guide 21 around an axis parallel to the left-right direction (second axial direction).

  The wheel guide 21 is arranged inside the guide frame 10, and the wheel W that has entered the entrance 11h is placed on the wheel guide 21. The wheel guide 21 is formed of a metal plate formed in a trough shape or a channel shape having a U-shaped cross section, which extends in the front-rear direction and has an upper opening as a whole, and has a width dimension capable of accommodating the wheel W. The left and right sides of the wheel guide 21 are close to the inner surfaces of the guide plates 13L and 13R, and are configured to be tiltable around the guide support shaft 22 within a predetermined angle range.

  The guide support shaft 22 is composed of a shaft-shaped component that extends in the left-right direction and penetrates the wheel guide 21, and both ends thereof are respectively positioned in a pair of guide plates 13L and 13R at positions slightly lower front than the rear guide shaft 14. It is fixed. The guide support shaft 22 is mounted near the rear end of the wheel guide 21 so that the front end of the wheel guide 21 swings in the vertical direction with the guide support shaft 22 as a fulcrum.

  When the wheel W is inserted into the entrance 11h of the guide frame 10, the wheel guide 21 takes a posture in which the front end is slightly lowered (bicycle parking position) due to the weight received from the wheel W of the bicycle. Normally, the front end stands still in a posture (non-parking position) in which the front end is slightly inclined upward. That is, the wheel guide mechanism 20 receives the weight of the wheel W from the non-parking position (solid line in FIG. 3B, see FIG. 4A) that can receive the wheel W that has entered the entrance 11h, and the wheel guide mechanism 20 receives the weight of the guide shaft. It is configured such that the bicycle can be tilted around the guide support shaft 22 to a bicycle parking position that is tilted around 22 (two-dot chain line in FIG. 3B, see FIG. 4B).

  As shown in FIG. 3B, the front end side of the wheel guide 21 has an upper and lower plate surface portion 211 extending downward, and the front and rear portions of the lower end of the upper and lower plate surface portion 211 are bent so as to be folded back. A plate surface portion 212 is provided. A square hole 211h (see FIG. 4A) as a hooked portion to be described later is opened in the upper and lower plate surface portions 211, and the front and rear plate surface portions 212 constitute a contact portion to be described later.

(Arm movable mechanism)
The arm moving mechanism 30 includes a pair of left and right lock arms 31L and 31R and a pair of arm support shafts that rotatably support the pair of lock arms 31L and 31R around an axis parallel to the front-rear direction (first axial direction). 32L, 32R.

  The pair of lock arms 31L and 31R are arranged substantially in the front and rear intermediate portions of the guide frame body 10 (the pair of guide plates 13L and 13R). The pair of lock arms 31L and 31R are housed inside the lock arm covers 33L and 33R attached to the pair of guide plates 13L and 13R, respectively. The pair of lock arms 31L and 31R are metal plate members each having a pair of pressed portions 311L and 311R located below the wheel guide 21 and a pair of hook portions 312L and 312R located above the wheel guide 21. Composed of.

  The pair of arm support shafts 32L and 32R are configured by axial members extending in the front-rear direction, and penetrate the elbow portions at the lower ends of the pair of lock arms 31L and 31R at the symmetrical positions. Both ends of the pair of arm support shafts 32L and 32R are respectively fixed inside the pair of lock arm covers 33L and 33R (see FIG. 1) that house the lock arms 31L and 31R and are fixed to the guide plates 13L and 13R.

  The pair of pressed portions 311L and 311R are provided at the lower end portions of the pair of lock arms 31L and 31R. The pair of pressed portions 311L and 311R are located at the mounting positions (the elbow portions) of the pair of guide support shafts 32L and 32R, and the lower opening 13h1 (FIGS. 3B and 4A) provided in the pair of guide plates 13L and 13R. (Refer to FIG. 3), the arm portions project inward so as to be close to each other. The pair of pressed portions 311L and 311R support the bottom portion of the wheel guide 21, and when the wheel guide 21 tilts from the non-parked position to the parked position, the pair of lock arms 31L and 31R are connected to the pair of arm support shafts 32L and 32L. Rotate in the opposite directions around 32R.

  The pair of hook portions 312L and 312R are provided at the upper ends of the pair of lock arms 31L and 31R, and are configured by arm portions that project inward so that their tip ends face each other. The pair of hooks 312L and 312R guide the guides through the upper openings 13h2 (see FIGS. 3B and 4A) provided in the pair of guide plates 13L and 13R by the rotation of the pair of lock arms 31L and 31R. The plates 13L and 13R are configured to be able to project from the outside to the inside (see the chain double-dashed line in FIG. 3C and FIG. 4B). That is, the pair of hook portions 312L and 312R are configured to be swingable so as to advance and retreat in a direction orthogonal to the approach direction of the wheel W.

  The arm moving mechanism 30 further includes a lock arm spring 34. The lock arm spring 34 is composed of a coil spring suspended at the lower ends of the pair of lock arms 31L and 31R, and the pair of pressed portions 311L and 311R are biased upward so that the pair of spring hook portions approach each other. Tow. The pair of lock arms 31L and 31R are urged by the pulling force of the lock arm spring 34 in a direction in which the pair of hook portions 312L and 312R move away from each other.

  The traction force of the lock arm spring 34 is higher than the pressing force applied from the wheel guide 21 before wheel mounting to the pressed parts 311L and 311R, and the pressing force applied from the wheel guide 21 after wheel mounting to the pressed parts 311L and 311R. Is set lower than. Therefore, the pair of lock arms 31L, 31R retreat the pair of hooks 312L, 312R to the outside of the left and right guide plates 13L, 13R and the inner walls of the lock arm covers 33L, 33R when the bicycle is not parked. Therefore, it is stopped in the open state (posture) in which further rotation is restricted. As a result, the wheel guide 21 is pushed up to the non-bicycle parking position by the pair of pressed portions 311L and 311R and is stably maintained in the non-bicycle parking position.

  As shown in FIGS. 4A and 4B, of the left and right lock arms 31L and 31R, the right lock arm 31R has a substantially single plate shape, but the left lock arm 31L has a hook portion 312L at the front. It has a stepped shape that is separated in the direction. As a result, the pair of hook portions 312L. The 312Rs are spaced apart from each other with a predetermined distance D2 (second distance) in the front-rear direction (first axial direction). The size of the distance D2 between the pair of hook portions 312 and 312R is not particularly limited, and is preferably set to be equal to or larger than the distance D1 between the pair of guide plates 13L and 13R. In the present embodiment, the distance D1 is set. It is about 60 mm, which is equivalent to

(Bicycle parking operation (temporary parking))
When the user parks the bicycle Bc on the bicycle parking lock device 1, first, from the rear end 11 (entrance 11h) to the front end 12 so that the wheel W rides over the rear guide shaft 14 of the guide frame 10. Push the bicycle Bc toward. The wheel W that has passed over the rear guide shaft 14 is slightly dropped downward, is then placed on the wheel guide 21, and is further pushed forward to abut the front guide shaft 15 and move further. Is limited. After the wheel W is stationary, the left and right guide plates 13L and 13R maintain the self-supporting state.

  2 to 4 show, as an example, a state in which a 28-inch wheel W is housed in the guide frame 10. In this state, the wheel guide 21 tilts around the guide support shaft 22 due to the weight received from the wheel W to assume the parking position, and the wheel W is housed between the front guide shaft 15 and the rear guide shaft 14. If the wheel size is smaller than 28 inches, the amount of play in which the wheel W can move back and forth between the front guide shaft 15 and the rear guide shaft 14 increases. The guide support shaft 22 is in a position where it does not come into contact with any assumed size wheel.

  As shown in the wheel mounting state of FIG. 4B, the wheel guide 21 receives the load from the wheel W and tilts to the parking position, and the contact portion (front and rear plate surface portion 212) at the front end of the wheel guide 21 is locked by the lock mechanism. The forty case 41 rocks and stands still on the pedestal 411. In this state, the left and right lock arms 31L. The pressed portions 311L and 311R of 31R are respectively pressed downward, and the hook portions 312L and 312R at the tips of the left and right lock arms 31L and 31R rotate to the closest position shown by the chain double-dashed line in FIG. 3C. That is, the left and right lock arms 31L and 31R are closed. At this time, the hook portions 312L and 312R are approaching to a position narrower in width than the width dimension of the wheel W and have advanced into the spoke area. Therefore, in this state, when the wheel W is pulled upward, the rim of the wheel W has a positional relationship in which it is restricted by the hook portions 312L and 312R.

  However, this state is not the “locked state” described later, and therefore, if the bicycle Bc is lifted up or pulled forward (toward the rear), the left and right lock arms 31L are released according to the weight of the wheels W being removed. , 31R (pressed portions 311L, 311R) receives an upward pressing force by the pulling force of the lock arm spring 34, and the wheel guide 21 moves up while the left and right lock arms 31L, 31R open. Therefore, the bicycle Bc can be easily pulled out from the guide frame body 10. In this way, the state in which the bicycle Bc is placed, rather than the "locked state", is called the "temporary bicycle parking state" for convenience.

(Lock mechanism)
Next, the lock mechanism 40 will be described. 5A and 5B are views for explaining the configuration and operation of the lock mechanism 40, and (1) and (2) of A are a left sectional view and a rear view showing a state before the operation of the lock mechanism 40, respectively. (1) and (2) of B are a left sectional view and a rear view showing an operating state of the lock mechanism 40, respectively.

  The lock mechanism 40 is arranged below the front ends of the left and right guide plates 13L and 13R. The lock mechanism 40 has a box shape as a whole, and includes a case 41 having a pedestal portion 411 protruding to the rear side at a lower portion and having a substantially L shape in a side view.

  A metal bracket 42 is fixed inside the case 41, and a solenoid 43 having a movable iron core (plunger) 431 movable in the vertical direction is fixed above the bracket 42. In addition, a lock lever support shaft 440 whose axial direction is oriented in the front-rear direction is fixed at an approximately middle position on the left and right sides of the case 41 at an upper and lower intermediate portion of the bracket 42, and an axial direction is oriented in the left-right direction at a lower portion of the bracket 42. The hook support shaft 450 is fixed.

  The lock lever support shaft 440 rotatably supports the lock lever 44. The lock lever 44 is entirely made of a metal plate bent in a U-shape, and has front and rear plate portions 441 and 442 in which shaft holes through which the lock lever support shaft 440 penetrates are formed. The plate portion 441 on the front side further has an arm portion 443 extending rightward, and the arm portion 443 is formed with a long hole 444 that engages with a pin 432 fitted to the axial center of the plunger 431.

  A connecting plate portion 445 that connects the front and rear plate portions 441 and 442 of the lock lever 44 is formed with a restricting portion 446 that extends downward and is folded back forward. A lever spring 46 is suspended between the pin 432 and the hook support shaft 450, and the plunger 431 is always pulled downward by the lever spring 46. When the solenoid 43 is in the suction state, the plunger 431 rises against the pulling force of the lever spring 46, and the arm portion 443 moves upward via the pin 432 accordingly. As a result, the lock lever 44 is held in a posture rotated around the lock lever support shaft 440 by a predetermined angle (see FIG. 5A(2)).

  The hook support shaft 450 rotatably supports the hook 45. The hook 45 is entirely made of a metal plate bent in a U shape, and has left and right plate portions 451 and 452 in which shaft holes through which the hook support shaft 450 penetrates are formed. The left plate portion 451 is located at the center of the left and right of the case 41, and a hook portion 453 and an abutted portion 454 that project rearward are provided at two positions above and below the left plate portion 451. A hook SW operation piece 455 is further provided on the upper end of the left side plate portion 451. The hook SW operation piece 455 projects laterally on the side opposite to the lock lever 44.

  The hook 45 is pulled forward by a hook spring 47. One end of the hook spring 47 is locked in a small hole provided in the upper and lower middle of the plate portion 451 on the left side of the hook 45, and the other end is suspended by a spring hook portion 421 protruding forward from the bracket 42. Therefore, the hook 45 is towed so as to always fall forward with the hook support shaft 450 as a fulcrum.

  The hook portion 453 and the contacted portion 454 that protrude in the rearward direction of the hook 45 can respectively protrude outside from the openings 41h1 and 41h2 on the rear surface of the case 41. Normally, the hook 45 is pulled by the hook spring 47 and is held in the posture in which it is rotated to the frontmost side (see FIG. 5A(1)). At this time, the contacted portion 454 projects upward from the opening 41h2 provided in the pedestal 411 of the case 41, and most of the hook portion 453 is pulled inside the case 41.

  A regulated portion 456 that engages with the regulating portion 446 of the lock lever 44 in a predetermined case is provided on the upper front side of the hook 45. When the solenoid 43 is attracted, the hook 45 can rotate about the hook support shaft 450 as a fulcrum without interfering with the restriction portion 446 of the lock lever 44. On the other hand, as will be described later, when the wheel guide 21 tilts to the parking position and the hook 45 rotates rearward, the suction of the solenoid 43 is released and the lock lever 44 turns, so that the restricting portion 446 and the restricted portion are controlled. The interference with the portion 456 prevents the hook 45 from returning to the original posture (see FIG. 5B).

  The lock mechanism 40 further includes a lock switch (lock SW) 48 and a hook switch (hook SW) 49. The lock SW 48 is attached to the front surface side of the bracket 42 and has a detector 481 that detects the attitude of the lock lever 44. The hook SW 49 is attached to the left side surface of the bracket 42 and has a detector 491 for detecting the attitude of the hook 45. The lock SW 48 and the hook SW 49 are typically configured by limit switches, and ON/OFF is switched by contact/non-contact with the lock lever 44 and the hook 45. The lock SW 48 is configured such that the detector 481 and the connecting plate portion 445 of the lock lever 44 contact each other in the solenoid released state shown in FIG. 5B, and the hook SW 49 causes the hook 45 to contact the wheel guide 21. The detector 491 and the hook SW operation piece 455 are configured to come into contact with each other in a state of being rotated rearward (see FIG. 5B).

  FIG. 5A shows a state where the solenoid 43 is attracting. The solenoid 43 is in a suction state when energized, pulls the plunger 431 upward, and releases the suction when deenergized. The solenoid 431 in the energized state moves the plunger 431 to the upper end, and the lock lever 44 stops at the most counterclockwise position in FIG. 5A(2). At this time, the restricting portion 446 is separated so as not to interfere with the plate portion 451 on the left side of the hook 45. In the state where the lock lever 44 is in the stopped posture, the detector 481 of the lock SW 48 is slightly separated from the plate surface of the lock lever 44, so the lock SW 48 is OFF. Further, since the hook SW operation piece 455 of the hook 45 is also slightly separated from the detector 491 of the hook SW 49, the hook SW 49 is OFF.

  When the wheel W is placed on the wheel guide 21 with the solenoid 43 attracted, as described above, the wheel guide 21 rotates toward the parking position in the accommodation direction indicated by the arrow A1 in FIG. 5A. The front and rear plate surface portions (contact portions) 212 of the guide 21 stop at the position where they come into contact with the pedestal portion 411 of the case 41. Then, the abutted portion 212 pushes the abutted portion 454 of the hook 45 downward, the hook 45 rotates rearward against the pulling force of the hook spring 47, and the hook portion 453 moves up and down the wheel guide 21. It will advance into the square hole 211h of the plate surface portion (hooked portion) 211 (see FIG. 5B). This state is the temporary parking state as described above, and if the wheel guide 21 rotates in the detaching direction, the hook can return to the original posture by the pulling force of the hook spring 47.

  FIG. 5B shows a state where the suction of the solenoid 43 is released (solenoid released state). When the solenoid 43 is de-energized, the plunger 431 of the solenoid 43 is released from its suction, and is moved downward by its own weight and the pulling force of the lever spring 46. Then, the lock lever 44 fitted to the pin 432 pivots clockwise in FIG. 5A(1), and the lower restricting portion 446 can advance into the space on the front side of the hook 45. Therefore, when the solenoid 43 is released after the wheel guide 212 has rotated in the housing direction, the restricting portion 446 of the lock lever 44 is located further forward of the restricted portion 456 of the hook 45, as shown in FIG. 5B. Therefore, the turning motion of the hook 45 toward the original posture is restricted. Therefore, even if the wheel guide 21 is returned in the disengagement direction indicated by the arrow A2 in FIG. 5B when the solenoid 43 is in the released state, the engagement between the hook portion 453 and the hooked portion 211 (square hole 211h) is maintained. Therefore, the wheel guide 21 cannot be returned in the detaching direction. Hereinafter, this state is also referred to as a "locked state".

  In the state of FIG. 5B, the detector 491 of the hook SW 49 is pushed by the hook SW operation piece 455, and thus the hook SW 49 is ON. Further, the detector 481 of the lock SW 48 is pushed by the connecting plate portion 445 of the lock lever 44, so that the lock SW 48 is ON.

[Connection configuration of bicycle parking system]
FIG. 6 shows an electric block of the bicycle parking system 100 of this embodiment.

  The settlement machine 6 has a CPU (Central Processing Unit) 611, a memory 612, and the like. When the CPU 611 executes a program recorded in the memory 612, the operation of the entire settlement machine 6 is controlled. The CPU 61 and the memory 612 are a display screen device 601, an operation key group 602, a voice output device 603, an external communication unit 604, an input/output unit 605, an RTC (Real Time Clock) 606, and a staff call button 607 via a bus and an interface. , Coin selector 608, bill reader 609, coin payout device 610, and the like. The input/output unit 605 is multi-drop connected to the control unit 51 of each bicycle parking lock device 1.

  Each bicycle parking lock device 1 has a control unit 51. The control unit 51 is electrically connected to the solenoid 43, the hook SW 49, the lock SW 48, the LED (Light Emitting Diode) 52, and the like, controls energization and release of the solenoid 43 and the LED 52, and controls the lock SW 48 and the hook. The ON/OFF state of SW49 is detected. The control unit 51 is typically composed of a computer, and has a storage unit for recording an ID corresponding to its own parking lock device number.

  The LED 52 is attached to, for example, the main body portion 50 of each bicycle parking lock device 1 (see FIG. 5 ), and has a function of visually displaying information regarding availability of the bicycle parking lock device 1 to the user.

[Operation of bicycle parking lock device]
Hereinafter, the details of the control unit 51 will be described together with the operation of the bicycle parking lock device 1.

  FIG. 7 shows an operation flow of the bicycle parking lock device 1 of the present embodiment.

  The solenoid suction state in FIG. 5A is the initial state, and at that time, both the hook SW49 and the lock SW48 are OFF. The LED 52 is ON and is lit. In this example, the lighting of the LED 52 indicates that the bicycle parking lock device 1 is in a usable state. As a result, when the power is cut off and the power is not supplied, the LED 52 is turned off, and the solenoid 43 is not in the suction state.

  First, the user inserts the bicycle Bc into the vacant parking lock device 1. The wheel guide 21 rotates in the accommodation direction A1 (the parking position) and the abutted portion 454 of the hook 45 is pushed. When the control unit 51 detects that the hook SW is turned on (step 1), it starts measuring the service time (step 2). The service time can be set by the settlement machine. For example, if you can park your bicycle for up to 5 minutes without paying the fee, the service time will be 5 minutes. If you want to control only the bicycle for a long time, the service time is about 30 minutes. Good. Of course, it is possible not to provide the service time, but in the case where they are installed side by side on the street, it is preferable to provide the service time for some time in consideration of the entry of people, which will be described later.

  The control unit 51 repeats monitoring whether the hook SW is turned off (Step 4) while monitoring the elapse of the service time (Step 3). If the user pulls out the bicycle and the wheel guide 21 is moved in the disengagement direction A2 (non-parking position) during the service time, the hook SW49 is turned off, and the process ends at that time. On the other hand, if the bicycle remains in the temporary parking state even after the service time has elapsed, the control unit 51 releases the solenoid 43 (step 5). The control unit 51 immediately monitors whether the lock SW 48 is turned on (step 6), and if it is on, turns off the LED 52 (step 7). If the lock SW 48 does not turn on even after the elapse of a certain time in step S6, an error (not shown) may occur and the process may be stopped.

  After turning off the LED (light off), the control unit 51 starts measuring the parking time (step 8). From this point onward, it is in the "locked state", so it can be returned to the "unlocked state" by paying the charge (there is also the possibility of paying 0 yen).

  The control unit 51 monitors whether the settlement has been completed (step 9). The control unit 51 calculates the fare from the bicycle parking time of the relevant bicycle parking lock device 1 after inputting the number, and sucks the solenoid when the settlement is completed (step 10). Next, the control unit 51 immediately monitors whether the lock SW 48 is OFF (step 11), and if it is OFF, blinks the LED 52 (step 12). This is because the bicycle parking lock device 1 that has been settled can be immediately recognized by the user by blinking the LED.

  After that, the control unit 51 monitors whether or not the hook SW 49 is turned off (step 13). During this period, the bicycle parking lock device 1 is in the “unlocked state”, which is the same as returning to the temporary bicycle parking state again. Therefore, when the user pulls out the bicycle in this state and the wheel guide 21 moves in the detaching direction A2 (non-parking position), the hook SW49 is turned off. Then, the control unit 51 turns on (turns on) the LED 52 and ends the process (step 14).

  If the service time of step S3 elapses before the hook SW49 is turned off in step S13, the operation of step S5 may be repeated. That is, when the settlement is once completed and the parking of the bicycle is continued, the locked state may be restored again.

  In the bicycle parking lock device 1 configured as described above, assuming that something other than wheels is placed on the wheel guide 21 by mischief, a surveillance camera or the like is often installed around the street. By this, mischief is suppressed, but in the state where people can enter along the street, it is possible that children and infants will come and go as adults.

  Here, the foot width of men's shoes is about 79 mm to 122 mm, and the foot width of women's shoes is about 76 mm to 112 mm, while the foot width of children's shoes is about 40 mm to 109 mm. It is known to exist (see the foot, shoes and health council website). In particular, in shoes having a foot length size of about 10.5 cm to 15 cm, which is considered to be intended for infants, a normal width E size has only a foot width of 60 mm. By the way, the size of the shoes of a 3-year-old child who is able to wander around various places by himself instead of walking is said to be 13 to 15 cm.

  When an infant enters the area around the bicycle-parking lock device 1, it is necessary to wear shoes having a foot length of 15 cm and a foot width of less than 60 mm to enter various places. The weight detection level of the wheel guide 21 set in the bicycle parking lock device 1 is, for example, about 7 kg in a lightweight folding bicycle, and when placed in the bicycle parking lock device 1, the front wheel or the rear wheel. Since one of them is placed on the wheel guide 21, when 3.5 kg, which is half the weight of the bicycle, is placed on the wheel guide 21, the wheel guide 21 needs to be pressed to operate properly.

  On the other hand, if the average height of a 3-year-old child is approximately 96 cm to 97 cm and the average weight is 13 to 14 kg, the wheel guide 21 and the lock arm spring 34 are set such that the 3-year-old child does not operate even when stepped on, but detects a lightweight bicycle. A solution with weight balance is impossible. Further, as described above, in order to cover the bicycle parking of a bicycle having a tire width of around 50 mm such as a mountain bike, the guide frame body 10 needs to have a width dimension of about 60 mm, and the width dimension may be narrowed. Not realistic.

  Therefore, in the bicycle parking lock device 1 of the present embodiment, the hook portions 312L and 312R of the pair of lock arms 31L and 31R that sandwich the wheel W from both sides of the guide frame body 10 are arranged in a direction parallel to the guide plates 13L and 13R. Direction) and are provided separately.

  As shown in FIGS. 4A and 4B, the right lock arm 31R has a substantially single plate configuration, whereas the left lock arm 31L has a lower half of the lock arm 31L that is substantially symmetrical with the right lock arm 31R. Although it is a single sheet, it is formed in a substantially Z-shaped bent state in which it is bent forward at a right angle at an intermediate portion in the up-down direction and is bent again at a position separated by about 60 mm at a right angle. In this configuration, as shown in FIG. 3C, the left and right lock arms 31L and 31R have a symmetrical shape when viewed from the front-rear direction, but only the upper hook portions 312L and 312R have a distance D2 (60 mm) in the front-rear direction. It is separated.

  In the locked state with this configuration, the hook portions 312L and 312R at positions spaced apart from each other in the front and rear directions in the spoke region inside the wheel W advance from the left and right, but either of the hook portions 312L and 312R. Since it also advances into the spoke area, it does not touch the rim of the tire. Further, if the bicycle Bc is pulled out in this state, the rim of the tire is limited by the hook portions 312L and 312R spaced apart from each other in the front and rear direction, and the front and rear direction of the tire is limited by the left and right guide plates 13L and 13R. Can only be tilted within the range of the distance between the guide plates 13L and 13R (distance D1, 60 mm in this example), the left and right hooks 312L and 312R are positioned in the same front-back direction and locked by the conventional parking. Similar to the wheel lock device, the wheels W are locked securely.

  8A and 8B are a top view and a left side view showing a state in which a model of the size of an infant's foot is inserted in the bicycle parking lock device 1.

  As shown in FIG. 8A, in the case of the size of the infant shoe SH having a width of 60 mm or less, the shoe SH enters (steps on) with the foot length direction substantially parallel to the inside (interval D1) of the left and right guide plates 13L and 13R. )be able to. At that time, even if the columnar portion F having a diameter of 50 mm assuming the ankle portion is hooked on the hook portions 312L and 312R of the lock arms 31L and 31R in the front-rear direction, it is not pinched from the left and right.

  As described above, according to the present embodiment, the foot of a passerby (especially an infant) who accidentally enters the inside of the guide frame body 10 is sandwiched by the hook portions 312L and 312R of the lock arms 31L and 31R from both the left and right sides. The danger can be avoided as much as possible.

  Further, in the bicycle parking lock device 1 of the present embodiment, the distance (distance D2) at which the hook portions 312L and 312R of the left and right lock arms 31L and 31R are separated in the front-rear direction is the left and right guide plates 13L of the guide frame body 10. , 13R and a size equal to or larger than the distance (distance D1). Therefore, since the left and right hooks 312L and 312R do not face each other directly to the object other than the wheel W that may enter between the guide plates 13L and 13R, the left and right hooks 312L and 312R do not contact the object. Even if a passerby wearing shoes whose width is narrower than the distance between the guide plates 13L and 13R enters his/her feet, the risk of being caught between the left and right hooks 312L and 312R is avoided.

  Further, in the bicycle parking lock device 1 of the present embodiment, the separation distance between the left and right guide plates 13L and 13R is 60 mm (55 m or more and 65 mm or less), and the separation distance in the front-rear direction between the left and right hook portions 312L and 312R is the above. The distance is 60 mm, which is equivalent to the distance. That is, although the bicycle can be parked on the mountain bike, the width of the guide frame body 10 (distance between the guide plates 13L and 13R) is narrowed down as much as possible, and the foot is sized so that it can still be stepped on. The above-mentioned separation distance of the portions 312L and 312R is set.

  Therefore, among the passers-by, the width of the guide frame body 10 is smaller than the size of the shoes for adults or young adults who are of junior high school age or higher, and at least a user who is supposed to use the bicycle parking lock device 1 is placed in the guide frame body 10. There is no stepping down. On the other hand, in the case of an infant among passers-by, there is a risk of stepping into the inside of the guide frame body 10 depending on the size of the shoe for an infant as described above, but the distance between the left and right hooks 312L and 312R is increased. Is provided at the same distance as the distance between the guide plates 13L and 13R, the risk that the foot of the infant is caught in the hook portions 312L and 312R of the lock arms 31L and 31R can be avoided as much as possible.

  As described above, according to the present embodiment, in the bicycle parking lock device 1 of the bicycle parking system 100 that controls the parking management by locking or unlocking the wheels of a two-wheeled vehicle, in particular, a bicycle in the unmanned management state, a passer-by other than a bicycle is used. Even if the user accidentally steps on the wheel guide 21 or the like, it is possible to eliminate the risk of injury, and it is possible to inexpensively realize the bicycle parking lock device 1 in consideration of such safety.

<Second Embodiment>
9A and 9B are a top view and a left side view showing a configuration of a bicycle parking lock device according to another embodiment of the present invention.
Hereinafter, configurations different from those of the first embodiment will be mainly described, and configurations similar to those of the first embodiment will be denoted by the same reference numerals, and description thereof will be omitted or simplified.

  The bicycle parking lock device 101 according to the present embodiment is common to the first embodiment in that it includes the guide frame body 110, the wheel guide mechanism 20, the arm moving mechanism 130, and the lock mechanism 40. The configurations of 110 and the arm moving mechanism 130 are different from those of the first embodiment.

  In this embodiment, the guide frame 110 has recesses 16L and 16R provided in the left and right guide plates 13L and 13R, respectively. The left and right recesses 16L, 16R are provided at positions facing the left and right hooks 312L, 312R in the left-right direction (second axial direction), respectively. That is, the one recess 16R is provided at the position of the guide plate 13R facing the left and right directions on the one hook portion 312L, and the other recess 16L is provided at the position of the guide plate 13L facing the left and right directions on the other hook portion 312R. To be

  The left and right recesses 16L and 16R are partially cylindrical shapes (semi-cylindrical shape) capable of cutting out a part of the guide plates 13L and 13R facing the hook portions 312L and 312R and covering the cutout portions 17L and 17R from the outside. ) Is formed. The width of the recesses 16L and 16R in the front-rear direction may be at least about 60 mm, and the recess amount (the depth in the left-right direction) may be at least 60 mm or more away from the tips of the hook portions 312L and 312R in the protruding state. Well, for example, it is about 30 mm.

  Regarding the vertical lengths of the recesses 16L and 16R, the upper ends need to be open, but the lower ends are lower than the heights of the hook portions 312L and 312R, for example, up to the height of both frames of the wheel guide 21. It just needs to be extended.

  Next, the arm moving mechanism 130 will be described. FIG. 10 is a perspective view of a main part showing details of the arm moving mechanism 130 in the bicycle parking lock device 101 of the present embodiment.

  In the present embodiment, the structure of the hook portions 312L and 312R is devised. That is, when viewed from the inside of the tips of the hooks 312L and 312R, the metal plates are folded back 180 degrees in opposite directions in the front-rear direction so that the ends of the metal plates are not exposed to the inside. The parts 312L and 312R are configured. As a result, the tips of the hook portions 312L and 312R are curved without being sharpened, so that the hook portions 312L and 312R may be injured even if the hook portions 312L and 312R accidentally come into contact with the foot of an infant who has accidentally stepped into the guide frame 110. Can be avoided.

  In the present embodiment, each of the left and right lock arms 131L and 131R has a U-shape that is open upward and is formed by connecting plate surfaces that are spaced apart in the front-rear direction at the bottom. The through-hole portions 361L, 361R, 362L, 362R respectively formed on the plate surfaces spaced apart in the front-rear direction are configured to penetrate the arm support shafts 32L, 32R to perform opening/closing operations in the left-right direction.

  Of these, the hook portion 312L of the left lock arm 131L is provided at the upper end of the front plate surface 352L, and the hook portion 312R of the right lock arm 131R is provided at the upper end of the rear plate surface 351R. The left and right pressed portions 311L and 311R are provided at the lower ends of the rear plate surfaces 351L and 351R, and the lock arm spring 34 is suspended between the rear plate surfaces 351L and 351R.

  The through hole portions 361L, 361R, 362L, 362R have a shape that allows relative movement of the left and right hook portions 312L, 312R with respect to the guide frame body 110 in the front-rear direction. That is, the through hole portions 361L and 361R formed on the rear plate surfaces 351L and 351R are loosely fitted to each other, which is slightly larger than the diameter of the arm support shafts 32L and 32R. Further, the through-hole portions 362L, 362R formed in the front plate surfaces 352L, 352R are formed as long hole portions that are long in the vertical direction, and are configured to fit the arm support shafts 32L, 32R.

  This allows the front plate surfaces 352L, 352R to swing in the front-rear direction with the through-hole portions 361L, 361R formed in the rear plate surfaces 351L, 351R as fulcrums. Further, since the through-hole portions 361L, 361R formed on the rear plate surfaces 351L, 351R are round holes slightly larger than the diameters of the arm support shafts 32L, 32R, the pulling force of the lock arm spring 34 is increased. The relative position between the left and right pressed portions 311L and 311R to be received is stably maintained.

  In this case, the upper opening 13h2 through which the hook portions 312L and 312R of the guide plates 13L and 13R are inserted is formed as a square hole having a wide gap in the front-rear direction with respect to the thickness of the hook portions 312L and 312R. It As a result, a predetermined movable range of the hook portions 312L and 312R along the front-rear direction is secured.

  As described above, in the bicycle parking lock device 101 of the present embodiment, the left and right lock arms 131L and 131R are formed of metal plates, and the left and right hook portions 312L and 312R are respectively opposite to each other in the front-rear direction. It is composed of a folded part that is folded back in the direction. Therefore, even if the hooks 312L and 312R come into contact with the foot of the infant who accidentally enters the guide frame 110, it is difficult to get injured, but the function that the rim of the bicycle wheel cannot be easily pulled out properly. Secured.

  Further, in the bicycle parking lock device 101 of the present embodiment, the left and right lock arms 131L and 131R are configured such that the hook portions 312L and 312R are movable in a direction (front-back direction) parallel to the guide plates 13L and 13R. As a result, even if a foot is caught between the lock arms 131L and 131R, the hook portions 312L and 312R move in the front-rear direction and escape, so that it is difficult for the foot to be caught and injured. Further, even if it abuts on the spokes of the wheels, it moves in the traveling direction and escapes. Therefore, it is possible to avoid a situation in which the hooks 312L and 312R hit the spokes and are not locked, and the wheels of the bicycle are securely locked.

  In the present embodiment, the lock arm spring 34 can exert the traction force in a neutral state with respect to the rocking in the front-rear direction in both the left and right lock arms 131L and 131R. In this case, the swinging back and forth is realized without a complicated component structure, but a separate member for holding the neutral position is separately provided so that the lock arms 131L and 131R can be surely opened/closed at the neutral position. May be added.

  Further, in the bicycle parking lock device 101 of the present embodiment, a substantially semi-cylindrical shape corresponding to the positions of the hook portions 312L and 312R is provided on the side wall portions of the guide plates 13L and 13R opposite to the advancing/retreating directions of the hook portions 312L and 312R. Recesses 16L and 16R are formed. Accordingly, even if the hook portions 312L and 312R come into contact with the foot of the infant who has accidentally stepped inside the guide frame 110, the foot easily escapes to the recessed portions 16L and 16R, and it is easier to avoid the injury. ..

  In this configuration, the guide plates 13L and 13R are provided with the recessed portions 16L and 16R, but the guide plates 13L and 13R in that portion are simply cut out, and only the cutout portions 17L and 17R are provided. The width of the portions 17L and 17R may be suppressed to such an extent that the wheels cannot escape, or an appropriate inclined portion may be provided so that the wheels that move forward and backward do not get caught at the ends of the cutout portions 17L and 17R.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications can be made.

  For example, in the above embodiment, the lock arms 31L, 31R, 131L, 131R are configured as a left and right pair, but the invention is not limited to this. For example, one hook is provided on one side and two hooks are provided on the other side. These may be arranged apart from each other in a direction parallel to the guide frame. When the recesses 16L, 16R or the cutouts 17L, 17R are formed in the guide plate as in the second embodiment, the recesses or cutouts are provided at positions facing the three hooks, respectively. It may be formed.

  Further, in the above embodiment, the plunger 431 is moved in the up-down direction by energizing or de-energizing the solenoid 43 constituting the lock mechanism 40. However, the solenoid 43 may be, for example, a latching solenoid or the like. Thus, a solenoid that can maintain the retracted state of the plunger without maintaining the energized state may be used. As a result, the power consumption of the bicycle parking lock device in the non-bicycle parking state can be suppressed.

  Further, in the above embodiments, the lock arms 31L, 31R, 131L, 131R are entirely made of a metal plate, but for example, the hook portions 312L, 312R or only the tips thereof are appropriately elastically deformable. May be composed of As a result, it is possible to prevent the injury while ensuring the locked state of the wheels and even if the hook portion comes into contact with the foot of the infant who has stepped on the guide frame body by mistake.

  In the bicycle parking lock device according to the present invention described above, the configuration of the guide frame bodies 10, 110, the wheel guide mechanism 20, the lock mechanism 40, and the overall configuration and operation flow of the bicycle parking system are the configurations of the embodiment. However, the essential technique of the present invention can be implemented in a bicycle parking system and a bicycle parking lock device having various configurations.

  INDUSTRIAL APPLICABILITY The present invention can be suitably used for a bicycle parking lock device used in a bicycle parking system that controls the parking management by locking or unlocking the wheels of a two-wheeled vehicle, especially a bicycle, under the unmanned management.
