  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 6 shows a cargo compartment 5 provided at the rear part of the vehicle body 3 of the vehicle 1, and a dish-like frame body 7 is installed below the floor (not shown) of the cargo compartment 5. The box 7 has two box storage portions 9 arranged in parallel in the vehicle width direction, and each box storage portion 9 has a drawer-type storage box 11 that is substantially rectangular in plan view so that it can be inserted and removed from the rear of the vehicle body 3. Has been. In FIG. 6, the storage box 11 stored in the box storage unit 9 on the left side and the floor panel that covers each box storage unit 9 from above are omitted.

  As shown in FIGS. 1 to 5, the storage box 11 includes a box body 13, a cover 17 that covers the front wall portion 15 of the box body 13, and a cover 17 and a front wall portion 15 of the box body 13. It consists of the locking device 19 according to the embodiment incorporated in between. A plurality of upper engaging protrusions 20a are integrally projected on the inner side of the upper end edge 20 of the cover 17 at intervals in the vehicle width direction (left and right direction in FIG. 1), and at the inner side of the lower end edge 21. In addition, a plurality of lower engagement projections 21a are integrally projected at intervals in the vehicle width direction. On the other hand, a protruding portion 23 is formed on the outer peripheral edge of the front wall portion 15 of the box body 13 so as to be integrally extended over the entire circumference. The joint recess 24a is integrally projected with a gap in the vehicle width direction so as to correspond to the upper engagement protrusion 20a, and a plurality of lower sides are provided on the lower end edge 25 of the overhang 23. The engaging hole portion 25a is integrally protruded with a gap in the vehicle width direction so as to correspond to the lower engaging protrusion portion 21a. The cover 17 engages the lower engagement protrusion 21a with the lower engagement hole 25a of the box body 13 from below and the upper engagement protrusion 20a with the upper engagement recess 24a of the box body 13. Is attached to the front wall portion 15 of the box main body 13 by being engaged from above.

  A substantially U-shaped insertion portion 17a is formed in the middle of the cover 17 in the vehicle width direction as viewed from the rear of the vehicle 1 into which the finger is inserted. On the other hand, in the middle of the lower end edge 25 of the overhang 23 of the box body 13 in the vehicle width direction, the two rising portions 26 rise on the outer side of the insertion portion 17a of the cover 17 in the vehicle width direction, The upper end portion of the portion 26 is integrally bridged by a horizontal first holding portion 27, and both the rising portions 26 and the first holding portion 27 form a substantially gate shape. Near the upper ends of both rising portions 26, one shaft hole portion 26a is formed penetrating in the lateral direction (see FIG. 2). In addition, a rectangular through hole 25b is formed in the lower end edge 25 on the outer side in the vehicle width direction of the both rising portions 26 one by one in the vertical direction, while a concave portion is formed on the box housing portion 9 side of the frame 7. A lock portion 7a made of is recessed in the storage position of the storage box 11 so as to correspond to the through hole 25b. Further, two bulging portions 24b are formed on the upper end edge portion 24 of the overhang portion 23 so as to bulge integrally corresponding to the both through holes 25b.

  The lock device 19 includes a substantially gate-shaped lock member 28 that is provided on the outside of the front wall portion 15 of the box body 13, that is, on the rear side of the vehicle 1 on the front wall portion 15 so as to be able to advance and retreat. The lock member 28 is integrally formed by two vertical portions 28a and a horizontal second sandwiching portion 28b that bridges the upper ends of the two vertical portions 28a. As shown in FIG. The lower end of the vertical portion 28a is engaged with the lock portion 7a on the storage portion 9 side to prevent the storage box 11 from being pulled out. On the other hand, the lower end of the vertical portion 28a is detached from the lock portion 7a by a backward movement as shown in FIG. Thus, the storage box 11 can be pulled out.

  Plate springs 29 as urging means are attached to both ends of the second clamping portion 28b of the lock member 28 by engaging the engaging groove 29a at the lower end thereof, and the upper end is brought into contact with the lower surface of the bulging portion 24b. ing. As a result, the leaf spring 29 biases the lock member 28 between the lock member 28 and the box body in a direction in which the lock member 28 is always engaged with the lock portion 7a.

  An operation lever 31 is pivotally supported on the outside of the front wall portion 15 of the box body 13 so that the lower end of the vertical portion 28a of the lock member 28 is detached from the lock portion 7a by the rotation of the operation lever 31. It is like that. Specifically, the operation lever 31 includes an elongate lever body 33 having a substantially U-shaped cross section composed of an upper wall portion 33a and a lower wall portion 33b on which a finger is hung. A rotation shaft portion 33c that is rotatably fitted in the shaft hole portion 26a of the portion 26 is integrally projected in the longitudinal direction (vehicle width direction). By providing the lever wall 33 with the upper wall portion 33a, the operability of the operation lever 31 is not hindered by preventing the finger from going above the rotation shaft portion 33c when the finger is placed on the lower wall portion 33b. Can be. The lever body 33 is clamped between the lower edge of the second clamping portion 28 b of the lock member 28 and the upper edge of the first clamping portion 27 of the box body 13 by the urging force of the leaf spring 29, and the locking member 28. In the engaged state with the lock portion 7a, a sandwiched portion 34 that protrudes substantially rearward of the vehicle 1 is integrally projected. When the storage box 11 is pulled out from the box storage unit 9, as shown in FIG. 5, a finger (not shown) is moved from the insertion part 17 a of the cover 17 to the lower side of the first clamping part 27 of the box body 13. By inserting and pulling the lower wall portion 33b of the lever main body 33 with a finger to rotate the sandwiched portion 34, the second sandwiching portion 28b of the lock member 28 is resisted against the urging force of the leaf spring 29. Thus, the lower end of the vertical portion 28a is separated from the lock portion 7a by moving in the counter-biasing direction (upward). As shown in FIG. 3, ribs 17b are integrally projected toward the front of the vehicle 1 on the back surfaces of both sides of the insertion portion 17a of the cover 17, and on the other hand, both the outer surfaces of the front wall portion 15 of the box body 13 are provided. Ribs 15a are also provided on the side of the rising portion 26 so as to project toward the rear of the vehicle 1, and the ribs 17b and 15a are opposed to the vertical portion 28a of the lock member 28 from the front and rear, and the lock portion 7a is tilted in the front and rear direction. I am trying not to.

  Therefore, according to the lock device 19, the lock member 28 can be easily detached from the lock portion 7a on the box storage portion 9 side by a simple manual operation by simply pulling the lower wall portion 33b of the lever body 33 of the operation lever 31 with a finger. The drawer of the storage box 11 can be allowed. Further, the lock member 28 can be easily engaged with the lock portion 7a on the side of the box storage portion 9 by a simple manual operation by simply releasing the finger from the lower wall portion 33b of the lever main body 33 of the operation lever 31, and the storage box 11 can be pulled out. Can be prevented. Such a locking device 19 is configured by a combination of a lock member 28, an operation lever 31, and a leaf spring 29, and is made simple and inexpensive compared to Patent Document 1 that requires an actuator and a complicated control system. Can do. Further, the clamped portion 34 of the operation lever 31 is clamped between the lower edge of the second clamped portion 28 b of the lock member 28 and the upper edge of the first clamped portion 27 on the box body 13 side, and the lock member 28 is clamped by the leaf spring 29. Since the holding portion 34 is urged in the holding direction, the operation lever 31 does not rattle and a stable locked state can be ensured.

  In the above-described embodiment, the lock member 28 is moved in the vertical direction, but the lock / unlock operation may be performed by moving in the left-right direction.

  Further, in the above embodiment, one leaf spring 29 is provided at each end of the second clamping portion 28b in the vehicle width direction of the second clamping portion 28b, but only one leaf spring 29 is provided at the center in the vehicle width direction of the second clamping portion 28b. Alternatively, a coil spring may be used instead of the leaf spring 29 as the biasing means. Further, the bulging portion 24b formed at the upper end edge 24 of the overhang 23 on the box body 13 side is omitted, and the upper end of the leaf spring 29 or the coil spring is directly applied to the upper end edge 24 of the overhang 23. You may make it contact.

  Furthermore, in the above embodiment, the lock portion 7a on the box storage portion 9 side is formed as a recess, but the lock portion 7a may be a through hole in addition to the recess.

  Furthermore, in the above-described embodiment, the case where the locking device 19 is applied to the storage box 11 disposed in the rear portion of the vehicle body 3 of the vehicle 1 has been described. However, in addition to the above-described embodiment, the storage provided in the instrument panel or the like Of course, the present invention can also be applied to a box other than the vehicle 1.
