Description

  The present invention relates to, for example, a locking device that locks a lid that is rotatably supported by an opening of an automobile console box in a closed position.

  Although this kind of conventional locking device is not specifically shown, it was developed for a double-open lid, and for the box body of the console box, there is a pair of left and right at both ends of the opening. A shaft hole for protruding and retracting a certain hinge rod is formed, and for the lid, a storage wall for storing the compression coil spring is integrally provided on the synthetic resin molded substrate, and a support wall for supporting the check lever is provided. On the other hand, the left and right operation buttons with cam pieces on the back are rotatably mounted via a decorative frame, and the moving body centered by the compression coil spring is arranged between the left and right operation buttons. (For example, refer patent document 1).

In actual use, the lid is securely locked in the closed position when the distal ends of the hinge rods in the pair of left and right are engaged in the corresponding shaft holes of the box body by elastic biasing force. On the contrary, by rotating either one of the operation buttons, the cam piece acts to bring the hinge rod on the same side closer to the elastic biasing force, and at the same time, the moving body is moved to the spring of the compression coil spring. If it is moved in the opposite direction against the pressure and stopped at its moving position via the check lever, the locked state of the lid can be easily released and the lid can be opened in a predetermined direction. It becomes.

  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to a preferred embodiment. A vehicular locking device according to the embodiment also has a lid that is rotatably supported by an opening of an automobile console box in its closed position. It was developed as a locking device that releasably locks, and is characterized by a box body B that is a main body provided on the vehicle side, and a lid L that is a rotating member that is rotatably supported by the box main body B. And a switch member S for locking and unlocking the lid L with respect to the box body B.

  First, the relationship between the box body B and the lid L will be described. As shown in FIGS. 1 and 2, two pairs of bearing portions 1 having a paired relationship are provided on one side of the box body B, while the lid L Are provided with two bearing portions 2 fitted between the bearing portions 1 in the respective pairs, and by inserting the pin 3 into each of the bearing portions 1 and 2, the lid L is attached. When the cover L is pivotally supported by the box body B and the lid L is rotated to the opening side of the box body B, the distal end portion of the rod 7 of the switch member S described later is formed in the other side portion of the box body B. The lid L is locked in the closed position, and the operating member 6 of the switch member S described later is operated in such a closed state so that the tip end of the rod 7 is connected to the shaft hole. 4 When the cover L is retracted from the inside, the locked state of the lid L is released and the lid L can be rotated in the opening direction. To have.

  Next, the switch member S will be described. As shown in FIGS. 3 and 4, the switch member S includes a synthetic resin base 5 fixed to the substrate La side of the lid L via a screw 30; A synthetic resin operating element 6 that moves along the longitudinal direction of the base 5, and a pair of synthetic resin rods 7 that appear and disappear in the shaft hole 4 of the box main body B according to the movement of the operating element 6. The base 5 has a flat U-shape in which a return spring 8 having a conical shape of the operating element 6 and a taper cap 9 attached to the tip of the return spring 8 are integrally stored in the center of the plate. A guide wall 10a for forming an interfering storage wall 10 and facing an interference arm 24 of an operation element 6 described later is tapered, and a rib 25 on the operation element 6 side described later is provided in the vicinity of the storage wall 10. Click nail 1 in contact with And has a deflectable providing up the.

  In addition to this, a large first block portion 12 that faces an operation portion 22 of an operation element 6 to be described later is connected to one end portion side of the base 5, and both side edges of the opening of the first block portion 12 are provided. The first guide wall 13 that guides the movement of the operation unit 22 is formed at the same time, and the stopper wall 14 that restricts the movement of the operation element 6 is formed at the back side of the first block unit 12. Thus, a second block portion 15 smaller than the first block portion 12 facing the operating portion 23 of the operation element 6 to be described later is connected, and the operating portion 23 is provided on both side edges of the opening of the second block portion 15. The second guide wall 16 that guides the movement is formed, and the restriction wall 17 that restricts the return amount of the operating element 6 to the normal position by the return spring 8 is formed on the back side of the second block portion 15. Yes.

  Further, both side walls interposed between the first block portion 12 and the second block portion 15 are applied to the narrow intermediate portion 6a of the operation element 6 to be described later from the upper side in the vicinity of the block portions 12 and 15. An elastic claw that forms a holding claw 18 that contacts and holds the operating element 6 in a movable manner, and similarly elastically contacts the narrow intermediate portion 6a of the operating element 6 from above to absorb the vertical play of the operating element 6 19 are individually formed in a paired relationship, and a curved elastic wall 20 that absorbs backlash in the left-right direction of the operating element 6 is integrally formed at the center of both side walls. One elastic wall 20 is provided on one side wall and two are provided on the other side wall, and these elastic walls 20 are arranged alternately on each side. In the figure, reference numeral 21 denotes a mounting hole for screwing the base 5 to the substrate La of the lid L.

  As shown in the figure, the operating element 6 has a configuration in which the intermediate part is narrow and the both end parts are wider than the operating part 22 and the operating part 23, and is stored in the storage wall 10 in the narrow intermediate part 6a. An interference arm 24 that interferes with the return spring 8 and the taper cap 9 is formed, and a rib 25 that abuts the click claw 11 of the base 5 is formed. A pair of cam grooves 26 having a C-shape for fitting the followers 7 a provided on the base end side of the rod 7 are formed to face each other. Therefore, when the follower 7a of each rod 7 is inserted into the opposing cam groove 26 and the operation element 6 is pressed against the base 5, the rods 7 come close to each other, When the pressing operation of the child 6 is released, the rods 7 are separated from each other by the spring pressure of the return spring 8.

  Therefore, when assembling such a switch member S, first, a state is obtained in which the return spring 8 having the taper cap 9 mounted therein is stored in the storage wall 10 of the base 5, and the operation section 22 is provided on the first block section 12 side. When the narrow intermediate portion 6a of the operation element 6 is pushed between the both side walls of the base 5 while the operating portion 23 faces the second block portion 15 side, the both side walls are formed. Each holding claw 18 and each elastic claw 19 are allowed to pass through the narrow intermediate portion 6a of the operation element 6 while expanding outward, so that, as shown in FIG. As a result, it is assembled so as to be movable with one touch. The rod 7 is assembled when the base 5 is fixed to the substrate La of the lid L.

  In this case, as described above, since the guide port 10a of the storage wall 10 of the return spring 8 has a tapered shape, it is centered by the synergistic action of this tapered shape and the tapered shape on the tapered cap 9 side. The return spring 8 and the taper cap 9 can be stored in a stable state in the storage wall 10.

Further, in this assembled state, as shown in FIG. 6, the interference arm 24 of the operation element 6 interferes with the return spring 8 through the taper cap 9 through the guide port 10 a of the storage wall 10. The operating element 6 is elastically urged to the normal position without rattling until the operating part 23 comes into contact with the regulating wall 17 of the second block part 15, and as shown in FIG. Since the claw 18 abuts against the narrow intermediate portion 6a of the operation element 6 from above and holds the operation element 6 so as not to be detached from the base 5, the first guide wall 13 and the second guide wall 16 described above are retained. In combination with this guiding action, smooth movement of the operation element 6 is ensured.

In addition, in this assembled state, as shown in FIG. 8, the elastic claws 19 formed on both side walls of the base 5 are elastically contacted with the narrow intermediate portion 6a of the operating element 6 from above. When the child 6 moves, this can effectively absorb the vertical play, and as shown in FIGS. 5 and 6, three elastic walls 20 formed alternately on both side walls of the base 5 are provided. Since both the side surfaces of the narrow intermediate portion 6a of the operation element 6 are elastically contacted, the backlash in the left-right direction can also be effectively absorbed when the operation element 6 moves.

  Therefore, after that, if this unitized switch member S is fixed to the substrate La side of the lid L, the switch member S can be used for this purpose. As shown in FIG. 9, at least, a guide base 27 for guiding the movement of the pair of rods 7 is formed on the back surface of the substrate La, and the base 5 of the switch member S is screwed through the mounting hole 21. A plurality of bosses 28 to be stopped 30 are formed, and cutout holes 29 that allow the pair of rods 7 to protrude outward are formed on both sides of the substrate La.

  Therefore, the guide member 27, the boss 28, and the cutout hole 29 are used to insert the followers 7a of the pair of rods 7 into the cam grooves 26 formed in the operating portion 23 of the operation element 6 while switching members. If S is fixed to the substrate La of the lid L via the screw 30, the locking device itself is immediately incorporated on the substrate La side as shown in FIG. If the bottom plate Lb is joined, the lid L incorporating the lock device is thereby completed. That is, in this embodiment, unlike the conventional one, the switch member S for locking and unlocking the lid L with respect to the box body B is previously unitized, so that the assembling work for the lid L is easy. Become.

  Therefore, the lid L is pivotally supported on the box body B by using the bearings 1 and 2 and the pins 3 described above, and the lid L is pivoted to the opening side of the box body B. Then, since the operating element 6 of the switch member S is elastically biased to the normal position by the spring pressure of the return spring 8, the follower 7a of each rod 7 moves to the maximum separated position of the opposing cam groove 26, Since the front end portion is engaged with the corresponding shaft hole 4 on the box body B side, the lid L is thereby securely locked at the closed position as shown in FIG.

  On the contrary, when releasing the locked state of the lid L, the operating element 6 of the switch member S is resisted against the spring pressure of the return spring 8 until the operating element 6 collides with the stopper wall 14 of the first block portion 12. In response to this, the operating portion 23 itself of the operating element 6 is also interlocked in the same direction, and this time, the follower 7a of each rod 7 is moved to the minimum distance between the opposing cam grooves 26. Thus, the locked state of the lid L is released, and the lid L can be rotated in the opening direction as shown in FIG.

  In particular, in this case, the click 25 on the operating element 6 rides on the click claw 11 on the base 5 side and a click feeling is generated, so that a good operation feeling can be obtained, and the operating element 6 has an elastic claw. 19 and the elastic wall 20 ensure the smooth movement without rattling. Further, if a rubber (not shown) is mounted inside the return spring 8, it is possible to suppress the generation of noise in the return spring 8 itself accompanying the movement of the operation element 6.

  In the vehicle locking device according to the present invention, the switch member that locks and unlocks the rotation member with respect to the main body can be unitized, so that the switch member that is unitized can be rotated via the base. Since it can be used immediately if it is fixed to the member side, it is necessary to integrally mold important parts and members that are likely to be warped and distorted on the synthetic resin substrate of the lid as in the past. As a result, if it is used as a locking device for a lid that is rotatably supported by the opening of the automobile console box, it becomes more convenient.
