FIG. 1 is a view for explaining an opening / closing member 12 to which a locking device 10 according to the embodiment is attached. 1A is a front view of the locking device 10 and the opening / closing member 12 when the opening / closing member 12 is viewed from the front side, and FIG. 1B is a rear view of the locking device 10 and the opening / closing member 12 when the opening / closing member 12 is viewed from the back side. FIG. The opening / closing member 12 is actually provided so that two plate-like members are bonded together and the locking device 10 is accommodated therein. FIG. 1B is a back side of the opening / closing member 12 covering the locking device 10. This is illustrated with the plate-like member omitted.

The opening / closing member 12 is, for example, a lid member for a vehicle glove box. The opening / closing member 12 in FIGS. 1A and 1B is shown in a planar shape for convenience of explanation, but in practice it may be formed in accordance with the shape of the opening of the glove box and may be formed in a curved shape. Good. The glove box is a fixing member having a recess which is a storage space provided in the dashboard, and the opening / closing member 12 is rotatably attached to the glove box and opens and closes the opening of the recess.

The opening / closing member 12 is formed with an attachment port 12a for attaching the lock device 10. The locking device 10 attached to the opening / closing member 12 locks the opening / closing member 12 with respect to the opening of the glove box and holds it in the closed state. The lock device 10 according to the embodiment may be a side-type lock device that allows the operation member 20 to be operated in the width direction of the opening / closing member 12.

The locking device 10 includes an operation member 20, a base member 22, a rotating member 24, a first rod 26, and a second rod 28. The base member 22 is fixed to the opening / closing member 12. The operation member 20 is rotatably supported by the base member 22. As shown to Fig.1 (a), the operation member 20 is assembled | attached from the front side of the attachment port 12a, and is provided in the front side. The user releases the lock by inserting a finger into the back side of the operation member 20 from the recess 12 b and pulling the operation member 20.

The rotating member 24 is rotatably supported by the base member 22 and is connected to a first rod 26 and a second rod 28 (simply referred to as “rod” if they are not distinguished from each other). The operating force of the user is transmitted from the operating member 20 to the first rod 26 shown in FIG. 1B, from the first rod 26 to the rotating member 24, and from the rotating member 24 to the second rod 28. The rotating member 24 rotates according to the rotation of the operation member 20. The rod moves in the longitudinal direction in conjunction with the rotation of the rotating member 24.

The first rod 26 is inserted through the first support hole 12c of the opening / closing member 12, and the second rod 28 is inserted through the second support hole 12d. When the back side of the locking device 10 is obscured by the back side opening / closing member 12 (not shown in FIG. 1B), the tip end portion of the first rod 26 protrudes to the outside through the first support hole portion 12c. The distal end portion of the second rod 28 comes out to the outside through the support hole portion 12d. In the first rod 26 and the second rod 28, the side inserted into the first lock hole 14 a and the second lock hole 14 b is referred to as the distal end, and the side connected to the rotating member 24 is referred to as the proximal end.

The first support hole portion 12 c and the second support hole portion 12 d of the opening / closing member 12 are through holes formed in the side portion of the opening / closing member 12. A guide portion that guides the movement of the rod while elastically contacting the rod and suppressing the rattling of the rod may be provided at the periphery of the through hole.

When the user operates the operation member 20, the rotation member 24 rotates, and the rod enters and exits the first lock hole 14 a and the second lock hole 14 b formed in the glove box that is a fixed member in accordance with the rotation of the rotation member 24. To do. When the tip of the rod enters the lock hole of the glove box, the opening / closing member 12 is locked, and when the rod comes out of the lock hole, the opening / closing member 12 is unlocked.

The locking device 10 of the embodiment is provided at a position deviated from the center of the opening / closing member 12 to one end in the width direction. Thereby, for example, it is possible to easily reach the lock device 10 of the glove box provided in front of the passenger seat from the driver's seat. Since the rotation member 24 supported by the base member 22 is arranged close to one side of the opening / closing member 12, the distance from the rotation member 24 to the first support hole portion 12c and the second support hole portion 12d is different. Therefore, the longitudinal lengths of the first rod 26 and the second rod 28 are different, and the first rod 26 is shorter than the second rod 28 in the longitudinal direction.

FIG. 2 is an exploded view of the locking device 10. FIG. 3 is an enlarged view around the first rod 26 of the locking device 10 shown in FIG. The operation member 20 includes a base part 35, an operation part 36, a pair of shaft parts 38, a transmission part 40, a pair of side wall parts 42, an intermediate wall part 44, and a rotation stopper part 46. The operation unit 36 is formed on a flat base 35 and is positioned on the front side of the opening / closing member 12 so that a user can put his / her finger on the operation unit 36.

The pair of side wall portions 42 are erected facing the back surface of the base portion 35. The pair of shaft portions 38 are respectively formed in a circular arc shape on the pair of side wall portions 42. The pair of shaft portions 38 are disposed at positions closer to the transmission portion 40 than the operation portion 36 in the rod advance / retreat direction or the vehicle left-right direction.

The intermediate wall 44 is erected on the back surface of the base 35 and connects the pair of side walls 42. The intermediate wall portion 44 covers the internal structure of the lock device 10 and prevents the user's fingers from entering the lock device 10.

The transmission part 40 is formed in a columnar shape, stands up from the back surface of the base part 35, and protrudes from the back side of the opening / closing member 12. The transmission unit 40 engages with the first rod 26 and transmits an operation force to the operation member 20 to the first rod 26. The transmission part 40 has a contact surface 40 a that is curved and formed on the distal end side of the transmission part 40. The tip of the transmission part 40 has a receiving surface 74 of the first rod 26 and a gap 71.

The rotation stopper 46 is formed to protrude from the side surface of the columnar transmission part 40. When the operation member 20 is pulled by the user, the rotation stopper 46 is hooked on the base member 22 at a predetermined rotation position to stop the rotation of the operation member 20.

The base member 22 has an insertion part 50, a bottom part 51, a support part 52, a cylindrical part 54, a stopper part 56, a shaft support part 58, and a fixing part 60. The fixing portion 60 is formed in a flange shape from the main body of the rectangular base member 22. The base member 22 is fixed to the opening / closing member 12 by inserting screws or the like into the holes of the fixing portion 60.

The insertion part 50 is formed as a through hole for inserting the transmission part 40 of the operation member 20 into the back side. The support portion 52 is formed in a hole shape in the bottom portion 51 and rotatably supports the shaft portion 64 of the rotating member 24.

The cylindrical portion 54 accommodates the rotating member 24. The stopper portion 56 is formed in an elastic claw shape and functions as a stopper for the rotating member 24. The stopper portion 56 is disposed between the cylindrical portion 54 and the insertion portion 50 in the forward / backward direction of the first rod 26, and is positioned between the transmission portion 40 and the rotation center 24 a of the rotating member 24. Thereby, compared with the case where the stopper part 56 is provided in the base end side of the 2nd rod 28, the locking device 10 can be reduced in size. The shaft support portions 58 are formed as arc-shaped protrusions, and a pair is formed on the outer surface of the insertion portion 50. The shaft support portion 58 is inserted into the shaft portion 38 and rotatably supports the operation member 20. In the base member 22, a cylindrical portion 54 that accommodates the rotating member 24 and an insertion portion 50 through which the transmission portion 40 is inserted are arranged side by side.

The rotating member 24 includes a disk part 62, a shaft part 64, a first protrusion part 66, a second protrusion part 68, and an overhang part 70. The shaft portion 64 is formed in a columnar shape at the center of the disk portion 62 and is rotatably supported by the support portion 52 of the base member 22. The shaft portion 64 protrudes toward the front side of the opening / closing member 12. The rotation axis of the rotation member 24 is arranged so as to intersect with the rotation axis of the operation member 20 and further to be substantially orthogonal. Thereby, the rotation plane (disk part 62) of the rotation member 24 can be arrange | positioned so that the surface or back surface of the opening / closing member 12 may be followed, and the thickness of the locking device 10 in the surface perpendicular direction of the opening / closing member 12 can be made thin.

The first projecting portion 66 and the second projecting portion 68 are formed on the surface opposite to the shaft portion 64 although the projecting direction projects in a direction along the shaft portion 64. The first protrusion 66 and the second protrusion 68 are located eccentric from the center of the disk part 62. The tips of the first protrusion 66 and the second protrusion 68 are formed in a substantially hemispherical shape. The rotating shaft of the rotating member 24 is orthogonal to the advancing and retracting directions of the first rod 26 and the second rod 28.

The projecting portion 70 is formed so as to project outward in the radial direction from the outer periphery of the disk portion 62, and contacts the stopper portion 56 of the base member 22 as shown in FIG. The overhanging portion 70 is located on the outer side in the radial direction from the first protrusion 66 and the second protrusion 68 from the rotation center 24 a of the rotating member 24. Thereby, the force applied to the stopper can be reduced by disposing the stopper of the rotating member 24 radially outward. The overhanging portion 70 is disposed between the rotation center 24 a of the rotating member 24 and the transmission portion 40 in the forward / backward direction of the first rod 26. Accordingly, it is possible to suppress the base member 22 from becoming large in the forward / backward direction of the first rod 26 while providing the protruding portion 70 on the outer peripheral side of the disk portion 62 of the rotating member 24.

The rotation center 24 a of the rotating member 24 is disposed at a position overlapping the transmission unit 40 in the forward / backward direction of the first rod 26. Thereby, the base member 22 can be reduced in size by arranging the transmitting portion 40 and the rotating member 24 side by side on the base member 22. As described above, the locking device 10 according to the embodiment is miniaturized by integrally assembling the operation member 20 and the rotation member 24 to the base member 22 and arranging the transmission unit 40 and the rotation member 24 side by side. Furthermore, in the locking device 10, the rotating shaft of the rotating member 24 and the insertion direction of the transmission unit 40 are arranged in parallel to reduce the thickness in the direction perpendicular to the opening / closing member 12.

The first rod 26 has a first connecting portion 72, a receiving surface 74, a first column portion 76, a second column portion 78, and a third column portion 80. The first rod 26 is shorter than the second rod 28, and advances and retreats to the first lock hole 14 a of the fixing portion 60 according to the rotation of the rotating member 24. The first connection part 72 is formed at one end of the first rod 26 and is connected to the first protrusion 66. Here, the connecting structure of the rotating member 24 and the first rod 26 will be described with reference to a new drawing.

FIG. 4 is a cross-sectional view of the rotating member 24 and the second rod 28. FIG. 4 shows a cross section taken along line AA of the locking device 10 shown in FIG. Note that the connection between the first rod 26 and the rotating member 24 is the same as the connection between the second rod 28 and the rotating member 24, and a description thereof will be omitted.

The second connecting part 82 is formed on both side surfaces of the rectangular connecting hole 75 and is formed in a pair of ribs extending in the longitudinal direction. The second connecting portion 82 is hooked on the flange portion 68 a of the second projecting portion 68. The elastic piece 73 is a both-side-supported piece that is formed in the connecting hole 75 and extends in the longitudinal direction, and elastically contacts the tip of the second protrusion 68 to suppress backlash.

The first connecting portion 72 of the first rod 26 and the second connecting portion 82 of the second rod 28 are slidably fitted to the rotating member 24 by being pushed into the protruding ends of the first protruding portion 66 and the second protruding portion 68. . The direction in which the first connecting portion 72 and the second connecting portion 82 are pushed into the first projecting portion 66 and the second projecting portion 68 is the direction from the back side of the opening / closing member 12 to the front side, and the transmission portion 40 of the operating member 20 is The direction is opposite to the direction of insertion into the insertion part 50 of the base member 22. Thereby, while the connection to the rotating member 24 can be facilitated, there is a possibility that the connection is released when a force in the protruding direction of the first protrusion 66 and the second protrusion 68 is applied.

Return to Figure 2. The first column portion 76 extends in the longitudinal direction and is orthogonal to the second column portion 78. The second column part 78 has a receiving surface 74 that contacts the transmission part 40 of the operation member 20. The third column 80 is bent from the second column 78 and extends in the longitudinal direction. The 1st pillar part 76 and the 3rd pillar part 80 are extended in parallel with a longitudinal direction. As shown in FIG. 3, the first rod 26 has a receiving surface 74 for engaging with the transmission portion 40 of the operating member 20, and the receiving surface 74 intersects the longitudinal direction of the first rod 26. The longitudinal direction of the first rod 26 is parallel to the forward / backward direction in which the first rod 26 moves forward / backward.

The second rod 28 is longer than the first rod 26, and advances and retreats into the second lock hole 14b of the fixed portion 60 according to the rotation of the rotating member 24. The 2nd rod 28 has the 2nd connection part 82 connected with the 2nd projection part 68 at one end.

The first spring 30 is a coil spring, and the shaft portion 64 of the rotating member 24 is inserted therein. One end of the first spring 30 is in contact with the rotating member 24, and the other end is in contact with the base member 22. The first spring 30 urges the rotating member 24 to urge the first rod 26 and the second rod 28 in the locking direction, that is, the direction of proceeding to the first lock hole 14a and the second lock hole 14b. The rotating member 24 biased by the first spring 30 is stopped when the protruding portion 70 contacts the stopper portion 56. Therefore, the biasing force of the first spring 30 is configured not to be transmitted to the operating member 20 through the first rod 26 in the locked state of the opening / closing member 12, and the receiving surface 74 of the first rod 26 and the transmitting portion 40 are configured. A gap 71 is provided between them.

The second spring 32 is a coil spring, and one end contacts the operation member 20 and the other end contacts the base member 22. The second spring 32 biases the operation member 20 in the closing direction so that the operated operation member 20 returns to the original position. The direction in which the operation member 20 is closed is a direction in which the operation member 20 rotated by the user returns to the original position. The cushion 34 is made of a rubber material, and is fixed to the base member 22 so as to come into contact with the operation member 20 in a closed state. The cushion 34 softens the contact between the operation member 20 and the base member 22 and suppresses the occurrence of a hitting sound.

FIG. 5 is a diagram for explaining the operation of the locking device 10. When the operation unit 36 is pulled by the user, the operation member 20 is rotated by the shaft unit 38 and the transmission unit 40 is also rotated. The contact surface 40a of the transmission unit 40 pushes the receiving surface 74 of the first rod 26, and the first rod 26 moves in the retreat direction. As the first rod 26 moves, the rotating member 24 rotates, and the second rod 28 also retracts in conjunction with the rotating member 24. Thus, the first rod 26, the rotating member 24, and the second rod 28 are interlocked with the operation of the operation member 20.

When the user releases his / her finger from the operation member 20, the rotating member 24 is urged and rotated by the first spring 30 to move the first rod 26 and the second rod 28 so as to advance to the lock hole. Further, the operation member 20 is biased by the second spring 32 and returns to the original position.

4 and 5, in the rotational axis direction of the rotating member 24, the distal end of the transmission portion 40 and the flange portion 66a of the first protrusion 66 are separated by a distance L3. That is, the transmission part 40 protrudes to the back side from the connection position (the lower surface of the flange part 66a) of the rotating member 24 and the first rod 26. Thereby, the overlap width of the rotating shaft direction of the receiving surface 74 of the 1st rod 26 and the transmission part 40 is fully securable. In addition, the connecting position of the receiving surface 74, the rotating member 24, and the first rod 26 can be disposed overlapping in the advancing / retreating direction of the first rod 26, and the first rod 26 is formed along the advancing / retreating direction. The height of the lock device 10 can be reduced in the rotation axis direction, and the lock device 10 can be downsized. In addition, while the lock device 10 is downsized, the distance from the shaft portion 38 to the transmission portion 40 can be increased to increase the advance / retreat distance of the first rod 26 with respect to the operation angle.

Further, by forming the contact surface 40a of the transmission unit 40 to be curved, the sliding between the rotating transmission unit 40 and the first rod 26 that goes straight can be made smooth. When the external force is not applied to the operation member 20, that is, when the operation member 20 is closed, the contact position of the transmission portion 40 with the first rod 26 is the rotation center 38a of the shaft portion 38 in the forward / backward direction of the first rod 26. It is located closer to the tip of the first rod 26. When the operation member 20 is rotated, the contact position of the transmission portion 40 with the first rod 26 exceeds the rotation center 38a of the shaft portion 38 in the advance / retreat direction of the first rod 26. It moves to the base end side (rotating member 24 side). As a result, when the operation member 20 is rotated, the transmission unit 40 first moves in the direction in which the transmission unit 40 stands (upward in FIG. 5), and increases the amount of engagement with the first rod 26. Can transmit operating force. Moreover, the length of the transmission part 40 can be shortened and the locking device 10 can be thinned by moving the transmission part 40 so as to increase the engagement with the first rod 26 when operated in the opening direction.

The rotation center 38a of the shaft portion 38 can be disposed on the front side of the operation member 20 by forming the shaft portion 38 in an arc shape. Thereby, compared with the case where the rotation center of the axial part 38 is formed in the side wall part 42, the locking device 10 can be reduced in thickness.

FIG. 6 is a diagram for explaining the operation of the locking device 10 when closing the opening / closing member 12. FIG. 6 shows a state where the first rod 26 is in contact with the opening edge 14 c of the glove box 14 in the middle of closing the opening / closing member 12.

The tapered surface 26a at the tip of the first rod 26 contacts the opening edge 14c, and the first rod 26 receives a reaction force in the retraction direction 86 and the opening direction 88 of the opening / closing member 12. The force in the opening direction 88 becomes a moment with the first support hole 12c as a fulcrum, and receives a moment in the direction 90 in which the first connecting portion 72 is disengaged.

By the way, the locking device 10 is arranged close to the driver's seat among the opening / closing members 12 positioned in front of the passenger seat, and the first rod 26 is configured to be short. Therefore, when the gap L1 between the first support hole portion 12c and the first connecting portion 72 is set short when the opening / closing member 12 is closed, the magnitude of the moment with the first support hole portion 12c as a fulcrum does not change. The force in the direction 90 in which the first connecting portion 72 is released becomes large, and the first connecting portion 72 and the rotating member 24 may be disconnected. As described above, the locking device 10 is arranged close to the driver side of the opening / closing member 12, so that the short first rod 26 and the rotating member 24 are easily disconnected.

Therefore, the rotation member 24 is arranged at a position far from the support position (first support hole portion 12c) of the first rod 26 so that the connection between the first connection portion 72 and the rotation member 24 is difficult to be disconnected. . Specifically, the rotating member 24 is disposed at a position farther from the first support hole portion 12 c than the transmission portion 40 of the operation member 20 in the forward / backward direction of the first rod 26. That is, in the base member 22, the support portion 52 that supports the rotating member 24 is disposed at a position farther from the first support hole portion 12 c than the insertion portion 50 through which the transmission portion 40 is inserted. Thereby, in the rotating member 24 and the operating member 20 assembled to the base member 22, the first rod is closed when the rotating member 24 is moved away from the first support hole 12 c from the transmission portion 40 of the operating member 20 and the opening / closing member 12 is closed. The force in the direction 90 in which the 26 first connecting portions 72 are released can be reduced.

Further, the rotating member 24 and the support portion 52 are disposed at a position farther from the first support hole portion 12c than the center position C of the base member 22 in the forward / backward direction of the first rod 26. Thereby, the rotating member 24 can be moved away from the first support hole 12c on the base member 22.

In the forward / backward direction of the first rod 26, the distance L1 between the first support hole 12c and the first connecting part 72 is longer than the distance L2 between the first support hole 12c and the first lock hole 14a. Accordingly, when the first rod 26 receives a reaction force from the glove box 14 when closing the opening / closing member 12, the force in the direction 90 in which the first connecting portion 72 is removed can be made smaller than the reaction force. In the forward / backward direction of the first rod 26, the distance L1 between the first support hole 12c and the first connecting part 72 is longer than the distance from the first support hole 12c to the tapered surface 26a.

As described above, the locking device 10 of the embodiment achieves downsizing and thinning, although the operation member 20 and the rotating member 24 are provided on the base member 22, but the arrangement of each member is limited. Since the first rod 26 is connected to the rotating member 24 on the base member 22, there is a possibility that the connection with the rotating member 24 may be disconnected, but the connection is difficult to disconnect by moving the rotating member 24 away from the fulcrum of the first rod 26. It is comprised so that it may become.

FIG. 7 is a diagram for explaining a modified locking device 100. The lock device 100 according to the modification differs from the lock device 10 shown in FIG. 2 in that a key device 94 is provided on the operation member 20 and a transmission unit 140 is provided on the key device 94. The key device 94 is provided to release the engagement of the first rod 126 of the operation member 20. The lock device 100 shown in FIG. 7 shows a state in which the key device 94 is unlocked.

The key device 94 is formed in a cylindrical shape, is fixed to the operation member 20, and is inserted into the insertion portion 50.
