(For example, refer to Patent Document 1).
Japanese Unexamined Patent Publication No. 2003-13647 (page 2-6, FIG. 1)

  However, in the conventional locking device, since the conversion mechanism can only cope with the swinging operation of the operation knob by either the pushing operation or the pulling operation of the operation knob, the locking mechanism is locked. The operation direction of the operation knob for releasing is predetermined. Therefore, for example, in order to change the operation direction of the operation knob of the glove box according to the design in the vehicle or as desired by the occupant, that is, to change from push-in operation to pull-out operation or from pull-out operation to push-in operation The lock mechanism, the operation knob, or the cam mechanism needs to be changed or the entire lock device needs to be replaced.

  Therefore, the object of the present invention is to cope with either the push-in operation or the pull-out operation of the operation knob that is performed for opening and closing the lid that opens and closes the opening formed in the vehicle interior. It is to provide a locking device that can be used.

  In order to solve the above-described problem, the lid locking device according to claim 1 is capable of releasing the lid that closes the opening formed in the vehicle compartment so that the opening can be opened and closed to a position where the opening is closed. A locking mechanism that engages with the locking mechanism, an operation knob that is operated to release the locking of the lid by the locking mechanism, and an operation that is connected to the locking mechanism via a connecting member and is provided with the operating knob And a cam mechanism for converting the force into a release force for releasing the lock mechanism, wherein the cam mechanism is provided on the operation knob and is shaken by the operation of the operation knob. A cam pin that moves, a cam groove that receives the cam pin, and a rotatable cam plate to which the connecting member is connected; and the locking mechanism places the lid in a position where the opening is closed. When it is locked, The cam pin is located when the cam pin is located at the center portion viewed in the longitudinal direction of the groove, and the cam pin is moved from the center portion of the cam groove to one of both end portions of the cam groove by operation of the operation knob. Regardless of the direction, the cam plate is rotated in the same direction, and the rotation of the locking mechanism releases the lid by the lock mechanism.

  The lid locking device according to claim 2 is the lid locking device according to claim 1, wherein the cam plate swings the cam pin when the locking mechanism is in a locked state of the lid. The cam groove is in a rotational posture with an inclination with respect to the moving surface.

  The lid locking device according to claim 3 is the lid locking device according to claim 2, wherein the lid has a pivot for opening and closing, and the locking mechanism is in a pivotal direction of the lid. The lid is unlocked by either one of a pressing force and a tensile force via the connecting member.

  The lid locking device according to claim 4 is the lid locking device according to claim 3, wherein the operation knob has a pivot, and can be swung by receiving a pushing operation or a drawing operation, The cam pin is arranged at right angles to the pivot direction of the operation knob.

  2. The lid locking device according to claim 1, wherein when the operation knob is operated to release the locking mechanism, the cam pin always moves from the center of the cam groove to the cam groove. The cam plate rotates in the same direction by moving to one of the pair of end portions. For this reason, the cam plate rotates in the same direction regardless of the movement direction of the cam pin that swings by the operation of the operation knob in the cam groove. For example, the operation knob can be pushed or pulled out. In any case, the cam mechanism converts the operation force applied by the operation knob into a release force for releasing the lock mechanism.

  In the lid locking device according to any one of claims 2 to 4, when the cam pin moves from the center of the cam groove to the end of the cam groove, the cam pin comes into contact with the cam groove, The cam plate is rotated because the contacted portion moves while being urged in the moving direction. At this time, regardless of which of the cam pins moves to either end of the cam groove, the cam groove has an inclination with respect to the surface formed by the swinging motion of the cam pin and is at a longitudinal center position. Since it extends across the surface, the shape of the cam groove and the direction in which the cam pin urges the cam groove is point-symmetric about the center position in the longitudinal direction of the cam groove. The cam plate rotates in the same direction.

  In the locking device according to the present invention, when the operation knob is operated to release the locking mechanism, the cam pin always moves from the center of the cam groove to the end of the cam groove, Regardless of the direction of movement of the cam pin in the cam groove, the cam plate provided with the cam groove rotates in the same direction. Therefore, according to the present invention, for example, even when the operation knob is pushed or pulled out, the operation force applied by the operation knob is released from the locking mechanism. It can be converted into a release force to do.

  The present invention will be described in detail with reference to the embodiment shown in FIGS.

  FIG. 1 partially shows an example in which a locking device according to the present invention is incorporated in a glove box provided on an instrument panel of a vehicle.

When the operation knob 18 is not operated, that is, when the operation knob 18 is positioned within the plate thickness of the lid 14 at the knob opening 23, the cam pin 25 becomes the central portion in the longitudinal direction of the cam groove 26. The cam plate case 20 having the cam plate 19 is disposed on the back surface of the operation knob 18 so that the cam groove 26 is inclined with respect to the swinging surface of the cam pin 25 and located on the movement axis. With this arrangement, the shape of the cam groove 26 and the operation of the cam pin 25 that swings around the pivot 24 are point-symmetric about the rotation axis of the cam plate 19. For this reason, the rotatable cam plate 19 is moved in the same direction by the action of the cam pin 25 and the cam groove 26 regardless of which direction the cam pin 25 moves from the central portion of the cam groove 26 to both ends of the cam groove 26. Rotate.

  FIG. 3 shows a cross-sectional view taken along the line II-II shown in FIG.

  As shown in FIG. 3, the pair of locking mechanisms 21 includes a hollow cylindrical cylinder portion 27 attached to the lid body 14 and a piston portion 28 slidably disposed in the cylinder portion. The cylinder portion 27 is provided with a coil spring 29, and the piston portion 28 is urged toward the side end of the lid body 14 by the coil spring 29. A locking portion 30 is provided on the side end side of the lid 14 of the piston portion 28. The locking portion 30 protrudes in a cylindrical shape from the piston portion 28, and the locking portion 30 is caught at the opening 12 of the instrument panel 11 when the glove box 10 is accommodated in the instrument panel 11. An inclined surface (not shown) that prevents this is formed. The locking portion 30 is inserted through a through hole 31 formed in the storage portion 15 of the glove box 10 and engages with a locking hole 32 provided in the opening portion 12. The locking hole 32 is provided so as to engage the locking portion 30 at a position where the lid body 14 closes the opening 12 formed in the instrument panel 11. In the lock mechanism 21, the cylinder portion 27 is biased to the side end side of the lid body 14 by the coil spring 29, and the latching portion 30 is inserted through the through hole 31 and engaged with the latching hole 32 by this biasing. The lid 14 closes and locks the opening 12 formed in the instrument panel 11.

  The pair of connecting members 22 includes a wire 33 and a wire tube 34 that is inserted through the wire 33 and is attached to the lid body 14 for guiding the wire. One end of the wire 33 is attached to the cam plate 19, and the other end is attached to a surface urged by the coil spring 29 of the piston portion 28.

  Next, the operation method of the present embodiment will be described. FIG. 4 shows a cross-sectional view taken along line III-III shown in FIG.

  When the glove box 10 is used, in order to release the locking of the lid body 14 by the lock mechanism 21, the operation knob 18 is either pushed in or pulled out. As indicated by a two-dot chain line in FIG. 4, the operation knob 18 swings about the pivot 24 by this operation.

  When the push operation, that is, the operation knob 18 is pushed, the cam pin 25 extending from the operation knob 18 swings in conjunction with the swing of the operation knob 18, and moves upward on the upper end side of the lid body 14, that is, upward. It moves inside the cam groove 26. As shown in FIG. 3, when the cam pin 25 moves upward, the cam plate 19 rotatably supported by the cam plate case 20 is indicated by an arrow in FIG. 3 due to the action of the cam pin 25 and the cam groove 26. It rotates counterclockwise. When the cam plate 19 rotates counterclockwise, the pair of wires 33 attached to the cam plate 19 are pulled out from the wire tube 34, so that the piston portion 28 of the lock mechanism 21 is attached to the coil spring 29. Pulled so as to oppose the force, the locking portion 30 provided on the piston portion 28 moves to the storage portion 15 side. Thereby, since the latching | locking part 30 and the latching hole 32 stop engaging, the latching of the cover body 14 by the lock mechanism 21 is cancelled | released.

  When the other operation, i.e., the operation knob 18 is pulled out, the cam pin 25 extending from the operation knob 18 moves downward inward of the cam groove 26 in conjunction with the operation knob 18 (on the lower end side of the lid 14). Move to. When the cam pin 25 moves downward, as shown in FIG. 3, the cam plate 19 rotates counterclockwise by the action of the cam pin 25 and the cam groove 26 as in the case where the operation knob 18 is pushed. For this reason, the locking of the lid body 14 by the lock mechanism 21 is released. Thereby, the glove box 10 can be opened and used.

  Since the piston portion 28 is biased to the side end side of the lid body 14 by the coil spring 29, when the operation of the operation knob 18 for releasing the locking of the lid body 14 by the lock mechanism 21 is finished, the wire 33 is moved to the piston. By being pulled by the portion 28, the cam plate 19 rotates clockwise, and the operation knob 18 returns to the return position within the plate thickness of the lid body 14 at the knob opening 23. Further, when the coil spring 29 is biased to the piston portion 28, the locking portion 30 is inserted through the through hole 31 and protrudes from the storage portion 15.

  When the glove box 10 is housed in the instrument panel 11, the glove box 10 is pushed to rotate the glove box toward the instrument panel 11 (see FIG. 1). At this time, the locking portions 30 protrude from both ends of the storage portion 15, but since inclined surfaces (not shown) are formed at the tips of the both locking portions 30, the inclined surfaces are instrumental. The abutment portion 30 is urged against the urging force of the coil spring 29 by contacting the opening portion 12 of the panel 11. For this reason, since the piston portion 28 moves in the cylinder portion 27 against the bias of the coil spring 29, the locking portion 30 is buried in the through hole 31 of the storage portion 15. When the glove box 10 moves to a position where the glove box 10 is accommodated in the instrument panel 11, the locking portion 30 protrudes again from the storage portion 15 and engages with the locking hole 32. Thereby, the lid body 14 is locked by the lock mechanism 21 in a state where the glove box 10 is accommodated in the instrument panel 11.

  As described above, in the glove box 10 having the locking device 17 of the present embodiment, the cam plate 25 and the cam groove 26 cause the cam plate to be operated regardless of whether the operation knob 18 is pushed in or pulled out. 19 rotates counterclockwise and releases the locking of the lid body 14 by the lock mechanism 21 via the wire 33, so that the lid body 14 can be opened.

  The locking device 17 may be configured as follows. 5 and 6 are cross-sectional views similar to FIG. 4 showing a configuration different from the above-described embodiment.

  In the lock device 17 shown in FIG. 5, a restraining portion 35 for restraining the swing due to the pushing operation of the operation knob 18 is provided on the upper portion of the operation knob 18. This is configured such that the locking of the lid body 14 by the lock mechanism 21 can be released only by a pulling operation.

  In the locking device 17 shown in FIG. 6, a guide portion 36 is formed in the knob opening 23 of the lid body 14, and a pressing portion 37 having a shape that can be fitted to the guide portion 36 is disposed in the guide portion 36. The guide portion 36 has a cylindrical shape into which the operation knob 18 can be fitted. The operation knob 18 is swingably provided on the guide portion 36. The pressing part 37 is slidably fitted to the guide part 36. At the lower end of the pressing portion 37, an extending portion 37a that extends so that the lower end portion of the operation knob 18 can be pressed is provided. When the glove box 10 including the lock device 17 shown in FIG. 6 is used, the operation knob 18 swings with its lower end pressed by the extended portion 37a by pressing the pressing portion 37 and sliding the pressing portion. Thus, since the operation of the operation knob 18 is the same as when the push-in operation is performed, the locking of the lid body 14 by the lock mechanism 21 can be released.

  When the lock device 17 is configured as shown in FIGS. 5 and 6, for example, the glove box 10 including the lock device 17 that can perform either a push-in operation or a pull-out operation according to the design of the vehicle is provided. can do. 5 and 6, the operation method of the locking device 17 can be performed without changing the cam plate case 20 provided with the cam plate 19, the pair of locking mechanisms 21, and the pair of connecting members 22.
