Description

  The present invention relates to a detection device for detecting whether or not a body holder for ensuring the safety of passengers in a vehicle is normally closed.

  Vehicles such as theme parks and amusement parks are provided with a safety bar for passenger safety. FIG. 1 shows a safety bar 2 provided on a roller coaster. The safety bar 2 is lowered in the direction of arrow A from the shoulder of the passenger sitting on the seat 4 to hold the passenger's body. After confirming that all passengers have lowered the safety bar 2, the roller coaster is allowed to depart. Thereby, a passenger's safety can be ensured.

  In recent years, a system has been used in which whether or not the safety bar 2 of each seat is reliably lowered is detected by a sensor and the roller coaster is not started unless the safety bars 2 of all seats are lowered (Patent Document 1). . In this system, as shown in FIG. 2A, when the safety bar 2 is lowered in the direction of arrow A in FIG. 1, the detected piece 8a (see FIG. 8b is provided.

  When the safety bar 2 is lowered, the detected pieces 8a and 8b also rotate as shown in FIG. 2B. Proximity sensors 10a and 10b are provided corresponding to the positions of the detected pieces 8a and 8b shown in FIG. 2B. Therefore, the proximity sensor 10a, 10b can detect (closed detection) that the safety bar 2 has been lowered (closed).

  In FIG. 2, two proximity sensors 10a and 10b are used in order to ensure the operation even if the proximity sensor is broken.

JP2015-36273

  The extent to which the safety bar 2 can be lowered depends on the physique of the passenger. Therefore, the proximity sensors 10a and 10b need to be set so as to detect the closing over a predetermined angle range of the safety bar 2.

  However, since the detected pieces 8a and 8b approaching from the lateral direction with respect to the proximity sensors 10a and 10b are detected, it is not easy to set a position to start detection. As shown in FIG. 3, the timing at which the proximity sensor 10 starts detection is determined by two factors, ie, the axial distance X and the rotational distance Y between the proximity sensor 10 and the detected piece 8, and therefore adjustment is difficult. . Furthermore, when there are a plurality of seats, it is necessary to make the detection range of the proximity sensor 10 of each seat uniform, and more so.

  If a contact type sensor is used, the detection start position can be set accurately and adjustment is easy. However, compared with non-contact sensors such as proximity sensors, the contact type sensor has a problem that it is repeatedly used, that is, inferior in durability.

  Further, even if the adjustment is properly performed at the time of setting, there may be a situation in which appropriate detection cannot be performed due to a secular change or a change in use environment. Sensor detection status is unstable due to minute alignment changes between components (for example, change in rattling due to minute wear on the shaft, change in sensor detection range due to rise / fall of outside air temperature, etc.) Because it becomes.

Therefore, the present invention is easy to adjust so that it can be reliably detected that the body holding tool is stopped at a position within a predetermined range, or the state of detection due to secular change or change in use environment It is an object of the present invention to provide a passenger safety vehicle that can exhibit stability against fluctuations and increase the robustness of the system.

  Several independently applicable features of the invention are listed.

(1) (2) A passenger safety vehicle according to the present invention is a vehicle main body capable of placing a passenger in a predetermined position, and a body holder provided in the vehicle main body, and allows the passenger to get into the predetermined position. Passenger provided with a body holder configured to be movable between an open position and a closed position for restricting movement of the passenger's body, and a detection device for detecting that the body holder is in the closed position In the safety vehicle, the closed position of the body holder is formed with a width from a closed start position to a closed end position according to the movement of the body holder, and the detection device includes a detection member or A first member that is a sensor member, a second member that is a sensor member or a detection member corresponding to the first member, and the sensor member detects a closed state when the body holder comes to a closed start position. Close the body holder from the open position. The movement to the first position is transmitted to the first member, the first member is moved closer to the second member, the body holder moves past the closed start position, and the sensor member When the first member approaches the second member to such an extent that the closed state is stably detected, even if the body holder further moves toward the closed end position, the first member and the second member A passenger safety vehicle comprising a transmission member configured to maintain a positional relationship.

  Therefore, it is easy to make adjustments so that detection can be performed reliably even if the body holder is stopped at any position from the closed start position to the closed end position, or changes over time and changes in the usage environment. Therefore, it is possible to provide a passenger safety vehicle that can stably detect a change in the detection state due to the vehicle.

(3) The passenger safety vehicle according to the present invention is characterized in that the second member is provided on an extension line of a movement locus of the first member.

  Therefore, the adjustment is easy because it is only necessary to adjust in the direction on the extension line. Alternatively, it is possible to stably detect a change in detection state due to a secular change or a change in use environment.

(4) The passenger safety vehicle according to the present invention is characterized in that the second member is provided at a predetermined distance with respect to the movement locus of the first member.

  Therefore, the detection member need not be made larger than necessary.

(5) The passenger safety vehicle according to the present invention is characterized in that the transmission member is configured not to move the first member when maintaining the positional relationship between the first member and the second member. It is said.

  Therefore, the movement of the first member can be restricted and the positional relationship can be maintained.

(6) In the passenger safety vehicle according to the present invention, the transmission member is configured by an extendable rod or a biasing member, and the first member can detect the stable closed state with respect to the second member. When it reaches the position, it is fixed so as not to approach the second member any more.

  Therefore, the movement of the first member can be restricted and the positional relationship can be maintained.

(7) The passenger safety vehicle according to the present invention is configured such that the transmission member moves the first member and the second member together when maintaining the positional relationship between the first member and the second member. It is characterized by being.

  Therefore, the positional relationship can be maintained by moving both the first member and the second member.

(8) In the passenger safety vehicle according to the present invention, the sensor member is a distance sensor, and detects that the distance from the first member or the second member is equal to or less than a predetermined distance.

  Therefore, it can be configured using a distance sensor.

(9) The passenger safety vehicle according to the present invention is characterized in that the sensor member is an optical sensor and detects light blocking or passage by the first member or the second member.

  Therefore, it can be configured using an optical sensor.

(10) The passenger safety vehicle according to the present invention is characterized in that a part or all of a member for other uses that is not provided only for the sensor member is used as the detection member.

  Therefore, it is not necessary to prepare a special member for detection, and the configuration can be simplified.

(11) The detection method according to the present invention is a state of a body holder configured to be movable between an open position where a passenger can get into a predetermined position and a closed position where movement of the passenger's body is restricted. The relative position of the detection member with respect to the sensor member is moved as the body holder moves from the open position to the closed position, and the movement of the body holder stabilizes the sensor member. When the positional relationship between the detection member and the sensor member is such that the detection can be performed, the positional relationship is maintained even if the body holder further moves.

  Therefore, it is easy to make adjustments so that detection can be performed reliably even if the body holder is stopped at any position from the closed start position to the closed end position, or changes over time and changes in the usage environment. Thus, it is possible to provide a detection method that can stably detect the fluctuation of the detection state due to the above.

1. Configuration and Operation of Embodiment FIG. 4 shows an appearance of a passenger safety vehicle 20 according to an embodiment of the present invention. The passenger safety vehicle 20 shown in FIG. 4 is provided with four seats 24. In front of each seat 24, a safety bar 26 as a body holding tool is provided. The safety bar 26 includes two arms 26a arranged at intervals, and a contact portion 26b provided at the tip of the arm 26a, and is configured in an inverted L shape. The safety bar 26 is provided with an arm that descends on both sides of the passenger and a contact portion that connects these arms at the tip, and a T-shape that is provided with a contact portion at the tip of the arm that extends from between both feet of the passenger. Any shape / mechanism may be used as long as it can hold passengers.

  After the passenger sits on the seat 24, the contact portion 26b holds the passenger's body by pulling the safety bar 26 in the direction of arrow A. When it is detected that all passengers have properly pulled down the safety bar 26, the passenger safety vehicle 20 travels on the track 22.

  FIG. 5A is a perspective view of a detection device provided at the base portion of the arm 26a of the safety bar 26. FIG. A magnet 44 as a detection member is fixed to a sliding member 40 configured to be slidable. A magnetic sensor 52 as a sensor member is provided so as to face the magnet 44. The magnetic sensor 52 outputs a detection output when the magnet 44 approaches a predetermined distance, and is a kind of distance sensor. The disk 32 of the rotating shaft 30 and the sliding member 40 are connected by an extendable rod 38.

  FIG. 5B shows a side view. The arm 26 a of the safety bar 26 can be rotated in the direction of arrow A about the rotation shaft 30. In this figure, the position where the safety bar 26 is most opened is shown. The rotating shaft 30 is provided with a disk 32 that rotates together with the rotating shaft 30, and a bracket 34 is fixed to the disk 32. One end of a telescopic rod 38 is fixed to the bracket 34 so as to be rotatable about the pin 36.

  The other end of the telescopic rod 38 is fixed to the sliding member 40 so as to be rotatable about the pin 42. A magnet 44 is provided on the upper portion of the sliding member 40. Therefore, the magnet 44 moves as the sliding member 40 moves. The sliding member 40 is configured to be slidable on the sliding rail 46. The slide rail 46 is fixed to a base member 48 fixed to the housing of the passenger safety vehicle 20. A magnetic sensor 52 is fixed to the base member 48 by an attachment member 50.

  FIG. 6 shows details of the detection device 30. 6A is a plan view and FIG. 6B is a front view. A bracket 34 is fixed to the disk 32. A pin 36 passes through the through hole of the bracket 34 and the through hole at one end of the telescopic rod 38 and is fixed rotatably. A pin 42 penetrates the through hole at the other end of the telescopic rod 38 and the through hole of the sliding member 40 and is fixed rotatably.

  FIG. 7 shows a cross-sectional view of the sliding member 40. A magnet 44 is fixed to the sliding member 40. A convex portion 41 is provided at the lower portion of the sliding member 40. The guide rail 46 is provided with a concave portion 47 that fits into the guide rail 46, and the convex portion 41 of the sliding member 40 is slidably fitted therein. Therefore, the sliding member 40 and the magnet 44 are slidable in a direction perpendicular to the paper surface of FIG. 7 (the direction of arrow B in FIG. 6B). In the state shown in FIG. 6, since the magnet 44 and the magnetic sensor 52 are separated from each other, the magnetic sensor 52 does not detect the magnet 44.

  From the state (open position) shown in FIG. 5A, when a passenger sits on a seat (not shown) and the safety bar 26 is tilted in the A direction, one end of the telescopic rod 38 fixed to the bracket 34 is also rotatable. Rotate in direction A. As a result, as shown in FIGS. 8A and 8B, the sliding member 40 and the magnet 44 move in the direction of the arrow B and approach the magnetic sensor 52.

  As shown in FIGS. 9A and 9B, when the safety bar 26 is further tilted in the A direction and the distance between the magnet 44 and the magnetic sensor 52 falls below the detection threshold TH, the magnetic sensor 52 is detected as being closed. Output. In this embodiment, the magnetic sensor 52 starts to output a detection output of the closed state at a position (referred to as a closed start position) when the largest physique assumed as a passenger correctly wears the safety bar 26. Yes.

  When the passenger's physique is smaller than the assumed maximum, the safety bar 26 is further tilted in the A direction. Thereby, as shown in FIGS. 10A and 10B, the magnet 44 further moves in the B direction and approaches the magnetic sensor 52. In this embodiment, when the distance between the magnetic sensor 52 and the magnet 44 becomes the stable distance BD, the sliding member 40 is prevented from sliding any further. Here, this is achieved by forming the recess 47 of the guide rail 46 only halfway. The stable distance BD is a distance at which detection by the magnetic sensor 52 is most stably performed.

  Further, when the safety bar 26 is tilted in the A direction, the sliding member 40 remains at the position shown in FIGS. 10A and 10B, and the telescopic rod 38 is contracted (the distance from one end to the other end is shortened). Therefore, after the sliding member 40 can no longer slide, the safety bar 26 can be tilted in the A direction by a dimension that allows the telescopic rod 38 to be retracted (if no passenger is on the vehicle). Yes.

  In this embodiment, at least the safety bar 26 can be tilted in the A direction until the position (closed end position) when the smallest physique assumed as a passenger correctly wears the safety bar 26 is provided. The degree of expansion / contraction of the telescopic rod 38 is set.

  When the safety bar 26 is opened from the position shown in FIGS. 10A and 10B (when moved to the opposite side of the arrow A), the sliding resistance of the sliding member 40 is more than the expansion resistance of the telescopic rod 38. First, the telescopic rod 38 extends. When the safety bar 26 is further opened after the telescopic rod 38 is fully extended, the sliding member 40 slides in the direction opposite to the arrow B. Finally, the state shown in FIGS. 6A and 6B is obtained.

  11A to 11D show the relationship between the position of the safety bar 26 and the output of the magnetic sensor 52. In the open position of the safety bar 26 (the position of the safety bar 26 where the passenger can get on and off the predetermined position (chair)), the magnet 44 is further away than the detection threshold distance TH. The output of the sensor 52 is OFF (FIG. 11A). When the safety bar 26 comes to the closed start position, the magnet 44 becomes the threshold distance TH, and the output of the magnetic sensor 52 is turned on (FIG. 11B). When the safety bar 26 is further closed, the magnet 44 approaches the magnetic sensor 52 to a stable distance (FIG. 11C). When the safety bar 26 is further closed, the magnet 44 maintains a stable distance, and the telescopic rod 38 contracts.

  In this way, the magnet 44 is kept at a stable distance at which the detection by the magnetic sensor 52 is most stably performed. Therefore, the difference in the closed position of the safety bar 26 due to the difference in the passenger's physique and the like is absorbed and accurate detection is performed. be able to.

In this embodiment, the magnetic sensor 52 is provided on an extension line in the moving direction of the magnet 44. Therefore, it is only necessary to adjust the final mounting position only in the direction of the extension line, and the adjustment is easy.

2. Other embodiments
(1) In the above embodiment, the safety bar 26 that holds the body from the front side of the passenger has been described as an example. However, the present invention can be applied to general body holders that hold the passenger's body, such as a safety bar 26 that holds the body from the rear side of the passenger.

(2) Although the telescopic rod 38 is used in the above embodiment, a flexible member such as a spring member or rubber may be used instead.

(3) In the above embodiment, the magnetic sensor 52 is fixed and the magnet 44 is moved. However, the magnet 44 may be fixed and the magnetic sensor 52 may be moved.

(4) In the above embodiment, when the magnet 44 approaches the magnetic sensor 52 to a stable distance, the telescopic rod 38 is contracted. However, as shown in FIG. 12, when approaching a stable distance, both the magnet 44 and the magnetic sensor 52 may be moved while maintaining the distance.

  A distance holding member 53 having a thickness equal to the stable distance is provided on the surface of the sensor 52 facing the magnet 44. A sliding member 41 is also provided under the magnetic sensor 52 and is configured to slide on the guide rail 46. Further, instead of the telescopic rod 38, a link 39 that is rotatably held by pins 36 and 42 is provided.

  When the safety bar 26 is closed in the direction of arrow A, the magnet 44 moves in the direction of arrow B. When the distance is further approached and the stable distance is reached, the magnet 44 comes into contact with the distance holding member 53 and pushes it. Therefore, the magnetic sensor 52 moves with the movement of the magnet 44. At this time, the distance between the two remains the stable distance by the distance holding member 53.

  When the closed safety bar 26 is opened (moved in the direction opposite to the arrow A), the magnetic sensor 52 moves to the position shown in FIG. Since the magnetic sensor 52 is stopped by a stopper (not shown) so as not to move before this, if the safety bar 26 is further opened, only the magnet 44 moves in the direction opposite to the arrow B. Become.

(5) In the above embodiment, the closed start position (position where the sensor starts detection) and the position where the sensor stably detects the distance (stable position) are different positions. However, the closed start position may be matched with the stable position of the sensor.

(6) In the above embodiment, the detection device using the magnetic sensor 52 has been described. However, proximity sensors such as electrostatic sensors and laser sensors may be used.

(7) In the above embodiment, the magnetic sensor 52 that is a sensor is provided on the movement locus line of the magnet 44 that is the detection target. However, a sensor may be provided at a position away from the movement locus of the detection target.

  An example in which such an arrangement is realized using a photoelectric sensor is shown in FIG. 13 (can also be applied to a sensor other than an optical sensor). A light emitting element 50 and a light receiving element 52 are provided to face each other. The shielding member 54 that is a detection member does not shield light from the light emitting element 50 in the open position. The shielding member 54 moves along the locus M in conjunction with the movement of the safety bar 26. In the closed position, it moves to a position indicated by a broken line in the figure, and shields light from the light emitting element 50. Thereby, it can be detected that the light receiving element 52 has not received light and has reached the closed position. In this example, the position of the broken line in the figure is a position that can be detected stably. Therefore, even if the safety bar 26 is further closed by the same mechanism as in the above embodiment, the shielding member 54 may be held at this position. . According to this example, it is not necessary to increase the size of the shielding member 54 more than necessary.

  In the above description, light blocking is detected. However, a through hole is provided in the shielding member 54 so that light is transmitted through the through hole only when a predetermined position is reached, and this is detected. It may be.

  In the above, the example which provided the photoelectric sensors 50 and 52 in the position away from the movement locus | trajectory M instead of the movement locus | trajectory M was shown. However, the present invention can be similarly applied to other sensors such as a proximity sensor.

(8) In the above embodiment, the magnet 44 is provided as the detection member. However, a part of a member (such as a metal part) used for other purposes may also be used as a detection member.

(9) In the above embodiment, one set of detection member and sensor member is provided for one body holding tool. However, a plurality of sets of detection members and sensor members may be provided for one body holder so that the operation can be ensured even when the sensor or the like breaks down. In this case, as shown in FIG. 14A, a plurality of sets of magnets 44 and magnetic sensors 52 can be provided with only one sliding member 40 and telescopic rod 38. Further, as shown in FIG. 14B, a plurality of sets of the sliding member 40 and the telescopic rod 38 may be provided.
