Description

  The present invention relates to a locking device provided in a vehicle glove box or the like.

  Japanese Patent Laying-Open No. 2005-104192 discloses a lock device that locks a movable member that can be opened and closed with respect to a fixed member in a closed position with respect to the fixed member. The locking device includes first and second rods that extend in the left-right direction on the movable member, and a gear that is coupled to the first and second rods and synchronizes the first and second rods in opposite directions. And a lock receiving portion that is provided on the fixing member and from which the tip ends of the first and second rods enter and exit.

However, the conventional locking device has the following problems.
Since the gear is used, there is a possibility that the first and second rods and the gear are assembled (coupled) by shifting from the normal position. If the assembly position (connection position) of the first and second rods and the gear is shifted, the amount of fitting wrap between the left and right rod tip portions and the lock receiving portion will be different on the left and right sides. This may cause one-side hooks or defective rod removal.
Therefore, not only must the accuracy of the single gear and the first and second rods be satisfied, but when the rod and gear are assembled, the assembly position must be sufficiently managed in the process. The process management is very difficult.

  An object of the present invention is to provide a vehicular storage device that can suppress the hooking of the first and second rods and the failure of the rods to be pulled out as compared with the prior art.

The present invention for achieving the above object is as follows.
(1) A locking device that locks a movable member that can be opened and closed with respect to a fixed member in a closed position with respect to the fixed member,
First and second rods provided on one of the fixed member and the movable member, and connected to the first and second rods provided on one of the fixed member and the movable member. A link that synchronizes the rods in opposite directions, and a lock receiving portion that is provided on the other of the fixed member and the movable member and through which the first and second rods enter and exit,
The link includes a rotation shaft portion provided on one of the fixed member and the movable member, a first arm portion extending from the rotation shaft portion to one side, and a first arm portion extending from the rotation shaft portion to the other side. Two arm portions, connected to the first rod at the first arm portion, and connected to the second rod at the second arm portion,
The first rod includes a first rod-side protrusion that protrudes toward the link, and the second rod includes a second rod-side protrusion that protrudes toward the link.
The first arm portion of the link is provided with a first hole into which the first rod side protrusion is fitted, and the second arm portion of the link has the second rod side protrusion. A second hole into which the part is fitted,
The link is connected to the first rod by fitting the first rod-side projection into the first hole, and the second rod-side projection is fitted into the second hole. Connected to the second rod,
The first hole and the second hole have a long hole shape,

Locking device.

According to the locking device of (1) above, the link includes the rotation shaft portion and the first and second arm portions, and the second arm portion is connected to the first rod at the first arm portion. Since the first and second arm portions move in opposite directions when the link is rotated around the rotation shaft portion, the first and second rods are opposite to each other. It can be moved in sync with the direction. In other words, since the link is used, it is not possible that the first and second rods and the link are assembled in a shifted state, and the single product accuracy of the first and second rods and the link is satisfied. If it does, the front-end | tip position of a 1st, 2nd rod can ensure a regular position with respect to a lock | rock receiving part. Therefore, it can suppress that the amount of fitting laps with the lock receiving part of the 1st and 2nd rods differs in right and left compared with the past, and it can occur that the 1st and 2nd rods are caught on one side and are defective. It can be suppressed compared to the conventional case.
Also, the first and second rods can be connected to the link simply by fitting the first rod-side protrusion into the first hole of the link and the second rod-side protrusion into the second hole of the link. it can.
In addition, since the first and second holes have a long hole shape, the first and second rod-side protrusions restrain the longitudinal direction of the first and second holes in the first and second holes. I can suppress it. Therefore, the first and second rod side protrusions can move in the longitudinal direction of the first and second holes in the first and second holes. Therefore, even if a link rotates, it can suppress that the attitude | position of a 1st, 2nd rod inclines. As a result, even if the link rotates, sliding resistance generated between the first and second rods and the lock receiving portion can be suppressed.

The locking device 10 further includes an operation unit 60 as shown in FIG.

  The first and second rods 20 and 30 are preferably molded with the same mold (preferably with the same shape) in order to reduce mold costs. As shown in FIG. 2, the first and second rods 20 and 30 are arranged in correspondence with the left and right sides of the movable member 2. Since the 1st, 2nd rods 20 and 30 are arrange | positioned corresponding to the left-right direction both sides of the movable member 2, the installation property of the vehicle glove box apparatus is good. In addition, since the first and second rods 20 and 30 are arranged corresponding to the left and right side portions of the movable member 20, they can be locked not only on the left and right sides but also on both sides, causing deformation or malfunction of the movable member 2. It has become difficult. The first and second rods 20 and 30 extend in the left-right direction (vehicle left-right direction) of the movable member 2. In the first and second rods 20 and 30, the distal end portions 21 and 31 enter and exit the lock receiving portion 50 only when the movable member 2 is in the closed state.

  As shown in FIG. 3, the first rod 20 includes a first rod-side protrusion 22 that protrudes toward the link 40 in a direction orthogonal to the extending direction of the first rod 20. The first rod-side protrusion 22 is fitted into a first hole 42a provided in the link 40 (inserted or inserted). The second rod 30 includes a second rod-side protrusion 32 that protrudes toward the link 40 in a direction orthogonal to the extending direction of the second rod 30. The 2nd rod side projection part 32 is inserted in the 2nd hole 43a provided in link 40 (it is inserted and has entered).

  The cross-sectional shape of the first and second rod side protrusions 22 and 32 is circular. The first and second rod-side protrusions 22 and 32 are hooked on the peripheral edges of the holes 42a and 43a of the link 40 at the leading ends of the first and second rod-side protrusions 22 and 32, respectively. In order to prevent the holes 42a and 43a from being removed from the 40 holes, the prevention claws 23 and 33 are provided. As shown in FIG. 2, at least one of the first and second rods 20 and 30 is moved by the return spring 34 in the direction in which the movable member 2 is fitted into the lock receiving portion 50 (first and second rods). 20 and 30 are always biased (in a direction protruding from the movable member 2).

  The link 40 extends in the vertical direction. The link 40 includes a rotation shaft portion 41 provided on the movable member 2, a first arm portion 42 extending upward (one side) from the rotation shaft portion 41, and a lower side (other side) from the rotation shaft portion 41. And a second arm portion 43 extending in the direction.

  The link 40 is rotatably supported (attached) to the movable member 2 by the rotation shaft portion 41. The rotation shaft portion 41 is located at the center in the vertical direction of the link 40.

  As shown in FIG. 3, the first arm portion 42 is provided with a first hole 42 a into which the first rod side protrusion 22 is fitted. The first arm portion 42 is connected to the first rod 20 by fitting the first rod side protrusion 22 into the first hole 42a. The second arm portion 43 is provided with a second hole 43a into which the second rod side protrusion 32 is fitted. The 2nd arm part 43 is connected with the 2nd rod 30 by the 2nd rod side projection part 32 being inserted in the 2nd hole 43a.

The first and second holes 42a and 43a may have a round hole shape (Example 1) or a long hole shape (Example 2). The first and second holes 42 a and 43 a are provided at symmetrical positions with respect to the rotation shaft portion 41.
Since the link 40 is connected to the first rod 20 and the second rod 30 by the first and second arm portions 41 and 42, the first and second rods 20 and 30 are connected to the movable member 2. When the rod moves in the rod extending direction, it pivots around the pivot shaft 41 with respect to the movable member 2.

  The lock receiving portion 50 is formed of a hole or a recess provided in the fixing member 1. As shown in FIG. 2, the lock receiving portions 50 are provided on both the left and right sides of the movable member 2. One of the left and right lock receiving portions 50 can receive the tip portion 21 of the first rod 20, and the other of the left and right lock receiving portions 50 can receive the tip portion 31 of the second rod 30. Has been.

  Of the fixed member 1 and the movable member 2, the operation unit 60 may be attached to the fixed member 1 side, or may be attached to the movable member 2 side. In the illustrated example, the operation unit 60 is attached to the fixed member 1 side. The operation unit 60 is disposed at a position closer to the driver's seat than the center position in the left-right direction of the movable member 2 for improving the driver's operability.

The operation unit 60 includes a push-type knob 61 as shown in FIG. By pushing the knob 61, the link 40 is rotated and the first and second rods 20 and 30 fitted in the lock receiving portion 50 are pushed out from the lock receiving portion 50, and the locked state is released. When the movable member 2 is lifted by hand and rotated and closed, the inclined surfaces (not shown) of the tip portions 21 and 31 of the first and second rods 20 and 30 hit the fixed member 1 and are pushed by the fixed member 1. Also at this time, the link 40 rotates. When the movable member 2 reaches the closed position, the link 40 rotates and the first and second rods 20 and 30 are fitted into the lock receiving portion 50 and the lock device 10 is automatically locked.

Here, an operation common to the reference examples of the present invention and the examples will be described.
In the present invention, the link 40 includes a rotation shaft portion 41 and first and second arm portions 42 and 43, and the first arm portion 42 is connected to the first rod 30 and the second arm portion. 43, when the link 40 rotates around the rotation shaft 41, the first and second arm portions 42 and 43 move in opposite directions, and the first, The second rods 20 and 30 can be moved synchronously in opposite directions. In other words, since the link 40 is used, the first and second rods 20 and 30 cannot be displaced and assembled when the link 40 is assembled, and the first and second rods 20 and 30 are not assembled. As a result, it is very easy to manage the position of the link 40 and the link 40. Therefore, if the single product accuracy of the first and second rods 20 and 30 and the link 40 is satisfied, the tip positions of the first and second rods 20 and 30 are secured to the lock receiving portion 50. it can. Therefore, it can suppress compared with the past that the amount of fitting laps with the lock receiving part 50 of the 1st, 2nd rods 20 and 30 differs in the right and left, and the 1st and 2nd rods 20 and 30 Occurrence of missing defects can be suppressed as compared to the conventional case.

Since the conventional locking device uses a gear, a gear holder is required for holding the gear and preventing the gear and the first and second rods from coming off. In the embodiment of the present invention, the link 40 is used. For this reason, the link 40 is attached to the movable member 2 by the rotation shaft portion 41 and the first and second rods 20 and 30 are provided with the prevention claws 23 and 33 so that the link 40 is held and the link 40 and the first A link holder for preventing disengagement from the second rods 20 and 30 is not necessary. Therefore, the number of components of the lock device 10 can be reduced compared to the conventional case, and the cost can be reduced.

  Since the first rod side protrusion 22 is fitted into the first hole 42a of the link 40 and the second rod side protrusion 32 is fitted into the second hole 43a of the link 40, the first rod side protrusion 22 is fitted into the first hole 42a of the link 40, and the second rod side protrusion 32 is fitted into the second hole 43a of the link 40, so that the first and second rods 20, 30 and the link 40 are connected. Can be linked.

Next, parts specific to the reference examples and examples of the present invention will be described.
[Reference Example] (Figs. 1-6)
In the reference example of the present invention, as shown in FIG. 5, the first and second holes 42a and 43a of the link 40 have a round hole shape.
As shown in FIG. 6, the link 40 is in a direction (for example, a vertical direction) orthogonal to the extending direction of the first and second rods 20 and 30 when the operation unit 60 is not operated (when it is in the initial position). When the operation unit 60 is operated to the maximum (when it is in the maximum use position), it is at a position inclined α ° from the surface S to the other side. That is, the link 40 straddles the surface S at the center of the rotation range of the link 40.
As shown in FIG. 5, grooves for inserting the first and second rod-side protrusions 22 and 32 into the removal preventing claws 23 and 33 are formed in part of the peripheral edges of the first and second holes 42a and 43a. 42b and 43b are provided.

In the reference example of the present invention, since the first and second holes 42a and 43a have a round hole shape, the first and second holes 42a and 43a have a long hole shape as compared with the first and second holes 42a and 43a. It is possible to suppress the occurrence of a gap in the fitting portion between the rod-side protrusions 22 and 32 and the first and second holes 42a and 43a. Therefore, the first and second rods 20 and 30 can be reliably moved in the opposite direction by the same amount, which is effective for preventing the first and second rods 20 and 30 from being caught on one side and coming off.
Further, since the link 40 straddles the surface S in the center of the rotation range of the link 40, the first and second rod-side protrusions 22 and 32 are orthogonal to the rod extending direction when the link 40 rotates. Although moving in the vertical direction in FIG. 6, the moving range can be minimized.

[Example] (FIGS. 7 to 9)
In the embodiment of the present invention, as shown in FIG. 9, the first and second holes 42 a and 43 a of the link 40 have a long hole shape. The longitudinal directions of the first and second holes 42 a and 43 a are directions away from the rotation shaft portion 41 in a straight line.
When the operation unit 60 is not operated (when in the initial position), the link 40 is on one side from the surface S extending in a direction (for example, the vertical direction) perpendicular to the extending direction of the first and second rods 20 and 30. When the operation unit 60 is operated to the maximum (when it is in the maximum use position), the position is set so as to be inclined α ° from the surface S to the other side. That is, the link 40 is set so as to straddle the surface S at the center of the rotation range of the link 40.

  In the embodiment of the present invention, since the first and second holes 42a and 43a are elongated holes, the first and second rod-side protrusions 22 and 32 are within the first and second holes 42a and 43a. Restraining in the longitudinal direction of the first and second holes 42a and 43a can be suppressed. Therefore, the 1st, 2nd rod side projection parts 22 and 32 can move to the longitudinal direction of the 1st and 2nd holes 42a and 43a within the 1st and 2nd holes 42a and 43a. Therefore, even if the link 40 rotates and the positions of the first and second holes 42a and 43a move in the direction perpendicular to the longitudinal direction of the rod (vertical direction in FIG. 9), the first and second rods 20 , 30 can be prevented from tilting. As a result, even if the link 40 rotates, the sliding resistance generated between the first and second rods 20 and 30 and the lock receiving portion 50 can be suppressed.
