When the rotor member 34 rotates, the first rod 26 and the second rod 28 also move in the axial direction in conjunction with each other. The second rod 28 is formed in a step shape. When the key is applied, that is, when the key cylinder 22 is turned on, the rotation of the rotor member 34 is restricted, and the movement of the lock member is restricted. When the key cylinder 22 is turned off, the rotor member 34 is brought into a rotatable state.

  FIG. 2 is an assembly diagram of the locking device 12 and the opening / closing member 10. Here, the same or equivalent components and members shown in the drawings are denoted by the same reference numerals, and repeated description thereof is omitted as appropriate.

  The housing unit 20 to which the key cylinder 22 is attached is attached from the outside of the opening / closing member 10 to the attachment hole 10b. The first mounting portion 70 and the second mounting portion 71 of the housing unit 20 are locked to the edge of the mounting hole 10b. By integrating the housing unit 20, the attachment to the attachment hole 10b is easy.

  The first rod 26 and the second rod 28 arranged inside the opening / closing member 10 are connected to the rotor member 34 protruding from the mounting hole 10b. The protrusion 82 of the rotor member 34 is connected to the recess 26 b of the first rod 26, and the protrusion 84 is connected to the recess 28 b of the second rod 28. The housing unit 20 will be described in detail below.

  FIG. 3 is an assembly view of the housing unit 20. 4A is a front view of the housing unit 20, and FIG. 4B is a side view of the housing unit 20 in the axial direction. 5A is a rear view of the housing unit 20, and FIG. 5B is a side view of the housing unit 20. The axial direction refers to the direction of the rotating shaft of the operation member 40.

  The housing unit 20 includes an upper member 42 and a lower member 36. The lower member 36 is attached to the opening / closing member 10, and the upper member 42 is attached to the lower member 36. The upper member 42 is detachably provided from the lower member 36. The upper member 42 includes an upper main body member 38, an operation member 40, a biasing member 44, and a cushion member 46.

  The operation member 40 includes a cylinder hole 50, a cylinder holding part 52, a shaft support part 54, a handle part 55, a cover part 56, a transmission part 58, and a spring end support part 59. The operation member 40 is exposed to the outside and releases the locked state of the lock member in accordance with an operation by the user. As shown in FIG. 4A, a cylindrical cylinder hole 50 is formed in the center of the operation member 40. When the key cylinder 22 is inserted into the cylinder hole 50, the outer peripheral surface of the key cylinder 22 is held by the plurality of cylinder holding portions 52 protruding inward in the radial direction of the cylinder hole 50. Thus, the key cylinder 22 is accommodated in the cylinder hole 50 and fixed. The key cylinder 22 may be firmly fitted to the cylinder holding portion 52 and cannot be removed from the operation member 40.

  The plate-like cover portion 56 is formed so as to stand from the back surface of the operation member 40. The cover part 56 covers the coupling claw 64 at a predetermined closed position. A shaft support portion 54 is formed on one end side of the operation member 40, and a handle portion 55 that can be gripped by the user is formed on the other end side. The cover part 56 is provided closer to the handle part 55 than the cylinder hole 50.

  The transmission portion 58 is formed so as to stand from the back surface of the operation member 40 on the shaft support portion 54 side. The transmission portion 58 contacts the protrusion 83 of the rotor member 34 and rotates the rotor member 34 according to the rotation of the operation member 40.

  The shaft support portion 54 is formed in an arc shape and a groove shape on the side surface of the operation member 40. Note that the shaft support portion 54 is formed in a through-groove. The arc of the shaft support portion 54 follows the turning locus of the operation member 40. As shown in FIG. 4B, the shaft support portion 54 is connected to the bearing portion 62 of the upper main body member 38. Thereby, the operation member 40 is rotatably supported by the upper main body member 38. By forming the shaft support portion 54 in an arc shape, the center of the rotation shaft can be provided outside the operation member 40. Thereby, compared with the operation member which provided the center of the rotating shaft, the axial support part 54 can be made small without reducing the movement locus | trajectory of the transmission part 58, and the operation member 40 can be made thin. That is, by providing the center of the rotation shaft at a position separated from the outside of the operation member 40, the movement locus of the transmission unit 58 according to the rotation operation of the operation member 40 can be increased.

  One end of the urging member 44 is supported by the spring end support portion 59, the other end of the urging member 44 is supported by the upper body member 38, and the urging member 44 urges the operation member 40 in the closing direction. The cushion member 46 is a buffer member and is fixed to the upper main body member 38. The cushion member 46 reduces the impact when the operation member 40 closed by the urging member 44 comes into contact with the upper main body member 38.

  The upper body member 38 includes a through hole 60, a bearing portion 62, a coupling claw 64, a first hook portion 66, a second hook portion 68, and an insertion hole 67. The upper body member 38 is coupled to the lower member 36 and functions as a base for the operation member 40. A through hole 60 for receiving the cylinder hole 50 and the key cylinder 22 is provided in the center of the upper main body member 38. The bearing portion 62 is an arc-shaped protrusion that is formed in an arc shape and protrudes in the axial direction from the side surface of the upper main body member 38.

  A first hook portion 66 and a second hook portion 68 are formed on one end side of the upper body member 38, and two coupling claws 64 are formed on the other end side. The coupling claw 64 is an elastic body formed so as to be able to bend, while the second hooking portion 68 is a rigid body. The first hook 66 is also a rigid body. The first hook portion 66 and the second hook portion 68 have higher rigidity than the coupling claw 64. In the insertion hole 67, the transmission part 58 of the operation member 40 is inserted.

  The lower member 36 includes a lower body member 37, a torsion spring member 48, and a rotor member 34. The lower body member 37 includes a first attachment portion 70, a second attachment portion 71, a rotor attachment hole 72, a spring end receiving portion 74, a coupling hole 76, a hooking hole 77, and a hooking hole 78.

  The first attachment portion 70 and the second attachment portion 71 are formed on the side surface of the lower body member 37 and are used for attachment to the attachment hole 10 b of the opening / closing member 10. As shown in FIG. 5B, the first mounting portion 70 is locked in the mounting hole 10b.

  A part of the rotor member 34 is inserted into the rotor mounting hole 72, and the tip of the central shaft support portion 81 is engaged to mount the disk-shaped rotor member 34. One end of the torsion spring member 48 is supported on the spring end receiving portion 74 in the rotor mounting hole 72. The other end of the torsion spring member 48 is supported by the central shaft support portion 81 of the rotor member 34. The torsion spring member 48 biases the rotor member 34 in a predetermined rotation direction. The predetermined rotation direction is a direction in which the first rod 26 and the second rod 28 project outward, that is, a direction in which the first rod 26 and the second rod 28 are locked.

  Thus, the upper member 42 and the lower member 36 are configured. After hooking the first hook portion 66 and the second hook portion 68 into the hooking hole 77 and the hooking hole 78 of the lower member 36 shown in FIG. 5 (b), the coupling claw 64 is bent to engage with the coupling hole 76. The upper member 42 and the lower member 36 are coupled to each other to be unitized as the housing unit 20. Thereby, the operation of the operation member 40 can be confirmed in the housing unit 20.

  FIG. 6 shows a cross-sectional view of the locking device 12 attached to the opening / closing member 10. 6A is a cross-sectional view taken along line AA of the locking device 12 shown in FIG. 1A, and FIG. 6B is a line BB of the locking device 12 shown in FIG. It is a cross section. In FIG. 6B, the key cylinder 22, the lock member, and the inner cover 14 of the opening / closing member 10 are omitted.

  As shown in FIG. 6A, the distal end 28a of the second rod 28 projects outward from the insertion hole formed in the inner cover 14. Similarly, the tip 26a of the first rod 26 (not shown) projects to the outside of the inner cover 14. At least the engaging portion of the coupling claw 64 is exposed by the coupling hole 76. The opening (coupling hole 76) is configured to be covered with the cover portion 56 and not exposed to the outside when the operation member 40 is closed.

  As shown in FIG. 6B, the operation member 40 rotates. The user inserts a finger from the concave portion 10 a to the back side of the handle portion 55, pulls the handle portion 55 toward the user, and rotates the operation member 40 by the shaft support portion 54. The rotation operation of the operation member 40 is transmitted to the lock member via the rotor member 34, and the lock member is released from the lock hole of the glove box, and the lock state of the opening / closing member 10 is released. The opening / closing member 10 is opened by its own weight. When the user releases the operation member 40, the operation member 40 is returned to the original position by the biasing member 44, and the lock member is also returned to the original position by the torsion spring member 48.

  FIG. 7 is a view for explaining the removal of the upper member 42 from the opening / closing member 10. When removing the upper member 42, the operating member 40 is rotated in the opening direction to expose the coupling hole 76, and then a predetermined jig 16 is inserted into the coupling hole 76 to lock the coupling claw 64 to the coupling hole 76. Remove. That is, an opening (coupling hole 76) that exposes the locking of the coupling claw 64 to the outside is provided, and the locking can be released from the opening. The operation member 40 shown in FIG. 7 is in a fully opened state.

  Thus, in order to remove the upper member 42, it is necessary to rotate the operating member 40 in the opening direction. The operation member 40 cannot rotate if the key of the key cylinder 22 is on, and the movement of the lock member is also restricted. That is, the coupling hole 76 is configured not to be exposed to the outside when the movement of the lock member is restricted by the key cylinder 22. Thereby, when the key of the key cylinder 22 is turned on, the removal of the upper member 42 can be prohibited.

  FIG. 8 is a cross-sectional view for explaining the removal of the upper member 42. FIG. 8A and FIG. 8B are cross-sections at the same position as FIG. FIG. 8A shows the same state as the operation member 40 shown in FIG. FIG. 8B shows a simplified upper member 42 and lower member 36.

  In FIG. 8A, the user holds the handle 55 of the operation member 40 to fully open the operation member 40, and inserts the tip of the jig 16 into the coupling hole 76 that is opened from the outside. The inner surface of the coupling hole 76 is tapered so that the opening narrows from the outside toward the inside, and guides the jig 16 to the coupling claw 64.

  Since the coupling claw 64 has elasticity, when the locking portion of the coupling claw 64 is pushed by the jig 16, the coupling claw 64 is bent and unlocked. As shown in FIG. 8B, the rigid second hooking portion 68 is rotated by pulling the handle portion 55 and detached from the hooking hole 78. In this way, when the user presses the coupling claw 64 with the jig 16 with the operation member 40 fully open, the user can easily remove the upper member 42 by releasing the coupling between the lower member 36 and the upper member 42. After the upper member 42 is removed, the operation member 40 whose surface is damaged can be replaced, or the key cylinder 22 can be replaced by removing the key cylinder 22 from the operation member 40.

  Further, by providing the coupling claw 64 on the upper member 42, even if the coupling claw 64 is damaged when the jig 16 is pushed into the coupling hole 76 and bent, the upper member 42 on the side to be removed is provided. Therefore, the upper member 42 may be replaced. When the lower member 36 is damaged, it is necessary to remove the inner cover 14 of the opening / closing member 10 and to remove the first rod 26 and the second rod 28 in order to replace the lower member 36, which is costly. Thus, the cost in the case of damage can be held down by providing the release coupling pawl 64 on the upper member 42.

  FIG. 9 is a diagram for explaining a lock device 112 according to a first modification. FIG. 9A shows a lock device 112 attached to the opening / closing member 10, which is different from the lock device 12 shown in FIG. 1 in the coupling structure of the upper member 142 and the lower member 136, and the others are the same.

  In the lock device 112 of the first modified example, the positions of the elastic coupling pawl 164 and the rigid hooking portion 168 are opposite to those of the lock device 12. That is, the upper main body member 138 has a coupling claw 164 on the rotating shaft side of the operation member 40, and has a hooking portion 168 on the handle portion 55 side of the operation member 40.

  Since the coupling hole 176 is opened, the engagement of the coupling claw 164 is exposed in the opening / closing member 10. Further, the inner cover 14 of the opening / closing member 10 is provided with a release opening 14a. The release opening 14a is provided at a position close to the coupling hole 176 in the inner cover 14, and is provided at a position where the user can visually recognize the coupling hole 176 from the outside through the release opening 14a.

  When the jig 16 is inserted into the release opening 14a and the engaging portion of the coupling claw 164 is pushed by the jig 16, the coupling claw 164 is bent and released. When the user presses the handle portion 55, the upper member 42 rotates about the hook portion 168 and the hook portion 168 is detached from the hook hole 178. In this manner, the user can easily release the handle by pressing the handle portion 55 while pressing the coupling claw 164 with the jig 16.

  Here, in order to insert the jig 16 into the release opening 14a, the opening / closing member 10 needs to be in an open state. That is, when the opening / closing member 10 is closed and the movement of the lock member is restricted by the key cylinder 22, the release opening 14a and the coupling hole 176 are configured not to be exposed to the outside. Accordingly, the upper member 42 can be prevented from being removed when the opening / closing member 10 is closed and the key of the key cylinder 22 is turned on.

  FIG. 10 is a view for explaining a lock device 212 of the second modified example. FIG. 10A is a front view of the locking device 212, and FIG. 10B is a cross-sectional view taken along line DD of the locking device 212 shown in FIG.

  The lock device 212 includes an upper member 242, a lower member 236, and a lock member 226. The lock member 226 is slidably provided on the lower member 236. Although the lock member of the lock device 12 shown in FIG. 1 is of a type that moves to the side, the lock member 226 of the second modified example moves up and down according to the operation of the upper member 242. The lock member 226 is inserted into and removed from the lock hole of the glove box.

  The lower member 236 is attached to the opening / closing member 10. The upper member 242 functions as an operation member operated by the user, and releases the lock state of the lock member 226 according to the operation by the user.

  The upper member 242 is coupled to and supported by the lower member 236. The lower member 236 has a hooking hole 278 and a coupling hole 276. The upper member 242 has a coupling claw 264 having elasticity and a rigid hooking portion 268. The coupling claw 264 is locked in the coupling hole 276, the hooking portion 268 is hooked and locked in the hooking hole 278, and the upper member 242 is coupled to the lower member 236. The coupling hole 276 opens so that the locking of the coupling claw 264 is exposed to the outside.

  When removing the upper member 242, the user pushes the connecting claw 264 with a predetermined jig and bends it to release the locking. When the user pulls the handle portion 255 at the lower end of the upper member 242, the upper member 242 rotates about the hook portion 268 and the hook portion 268 is detached from the hook hole 278. In this way, the user can easily release it by pulling the handle portion 255 while pressing the coupling claw 264.

  The present invention is not limited to the above-described embodiments, and various modifications such as design changes can be added to the embodiments based on the knowledge of those skilled in the art. Embodiments described may also be included within the scope of the present invention.

  In the embodiment, the coupling claw 64 is provided in the upper member 42 and the coupling hole 76 is provided in the lower member 36, but this is not restrictive. For example, a coupling claw may be provided in the lower member 36, a coupling hole may be provided in the upper member 42, and the coupling hole may be exposed to open to the outside.

  In the embodiment, the aspect in which the bearing portion 62 is provided as the arc-shaped protrusion is shown, but the present invention is not limited to this aspect. The bearing portion may be a cylindrical protrusion that is formed in a cylindrical shape and protrudes in the axial direction from the side surface of the upper main body member 38. The bearing portion is slidably inserted into the shaft support portion 54.
