Description

[Detailed Description of the Invention] The present invention relates to a locking device provided on the free end side of the lid of containers for storing small items.

In containers for holding small items installed in restricted areas such as the interior of a car, if the locking member of the lid protrudes to the outside, it may get in the way and is also undesirable in terms of external design.

That's why this idea came about. To provide a lid locking device which can be locked in a container and which is easy to install and operate.

An example in which the present invention is applied to a console box of an automobile will be described below.

FIG. 1 shows the main body of a console box installed on the floor between the driver's seat and the passenger seat of an automobile, and the main body A
A first accommodating portion 12 and a second accommodating portion 13 partitioned by a partition wall 11 are formed in the housing.

As shown in FIG. 2, the first storage section 12 has a lid B.
is attached, and its proximal end is hinged to the main body A so that it can be opened and closed on the second storage section 13 side (
(not shown).

The locking device for the main body A of the lid B includes a locking member 4 and a locking member holding plate 3 that holds the member 4, as shown in FIGS. 3 to 8, both of which are made of polyacetal resin or the like. It is integrally molded from a rigid synthetic resin.

Note that the lock member holding plate may be formed integrally with the lid body B.

As shown in FIGS. 4 and 5, the locking member holding plate 3 has a vertically rising flange 31 on one end edge and a guide groove 33 in the center.

On both sides of the opening of the guide groove 33, there are claws 3 that protrude in opposite directions.
4 is formed.

On the other hand, a pair of boss portions 21 (FIG. 3) are formed downward on the back side of the free end side of the lid body B, and the locking member holding plate 3 is attached to the lower end surface of the boss portion 21 through a hole 35. It is fixed with screws.

In the attached state, the lock member holding plate 30 guide groove 33 is open toward the free end side of the lid B.

The locking member 4 has a rectangular shape as shown in FIGS. 6 to 8, especially FIG. An engaging end portion 411 for engaging the groove 33 is formed.

The first storage section 1 is located outside the lower end of the other leg section 42.
An engaging protrusion 421 that engages with a lock hole 121 (FIG. 3) formed in the wall surface of 2 is formed, and the upper end extends upward and outward so that the lock member can be activated by pushing with one hand. A pushing portion 422 is formed.

Further, below the pushing portion 422. Projections 4 on both sides in the width direction
23 is formed, and a groove 424 is formed between the protrusion 423 and the lower end surface of the pusher 422.

As shown in FIG.
5, and a stepped portion 426 is formed on the back side of the tapered portion 425.

The width of one leg 410 of the locking member 4 is set to allow sliding in the guide groove 33 of the locking member holding plate 30, and the tapered portion 425 is formed on both sides of the other leg 42 in the width direction. The width of the portion is slightly larger than the opening width of the guide groove 33 formed between the claw portions 34.

Further, the width of the groove 424 provided in the leg portion 42 is such that the locking member holding plate 3 can be inserted thereinto.

When assembling the locking member 4 to the locking member holding plate 3, first insert one of the legs 41 from its tip into the guide groove 33 of the holding plate 30 from below. The grooves 424 formed on both sides and the opening ends of the guide groove 33 of the lock member holding plate 30 are made to face each other, and the one leg portion 42 is pushed into the guide groove 33.

At this time, the engagement end 411 formed at the tip of the one leg 41 is pressed against the bottom of the guide groove 33 and locked, while the tapered part 425 of the one leg 42 pushes the opening of the guide groove 33 and expands. It enters the groove 33.

And the legs 42. The legs 410 having spring properties are pushed back by the reaction force.

The stepped portion 426 (FIG. 8) of the leg portion 42 is engaged with the inner side 35 of the claw portion 34 of the guide groove 33.

Next, to explain the operation of this locking device, when the free end of the lid body B is rotated in the closing direction from the open state, the tapered surface of the engaging protrusion 421 provided on the leg portion 42 of the locking member 4 4
21' is stopped by a guide wall surface 111 (FIG. 3) formed at the boundary between both storage sections 12 and 13 of the container body A.

When the free end side of the lid body B is further pushed down, the engaging protrusion 42
1 is guided by the guide wall surface 111 and moves downward, and at the same time, the leg portion 42 moves in the direction of the leg portion 41 while bending the leg portion 41 against the spring force of the leg portion 41.

In this case, the groove 424 of the leg portion 42 is guided and slid along the guide groove 33 of the lock member holding plate 30.

Note that the vertical movement of the lock member 4 with respect to the lock member holding plate 3 is restricted by the end surfaces of the push portion 422 and the end surfaces of the projection portion 423 that form the upper and lower surfaces of the groove 424.

Therefore, the engagement protrusion 421 of the leg 42 crosses over the guide wall surface 111 and the lock hole 121 formed in the lower part thereof.
When this occurs, the engaging protrusion 421 elastically enters the crest hole 121 due to the reaction force of the leg 410 and is locked.

On the other hand, when opening the lid B locked in this way,
Push portion 4 formed at the tip of leg portion 42 of lock member 4
22, the one leg portion 42 moves against the spring force in the same way as when closing the lid B described above, and the engagement protrusion 421 is disengaged from the lock hole 121, and the lid is closed. Lid body B is opened by lifting the free end of body B.

In the above embodiment, the locking member holding plate 3 was fixed to the lid B via the boss portion 21.

The holding plate 3 may be integrally molded with the lid B.

Also. The holding plate 3 may be provided on the main body A side.

In this case, the locking member 3 will be locked to the lid B.

As described above, the container lid locking device according to the present invention is composed of a resilient locking member formed in a square shape and a locking member holding plate that holds the locking member, and has a small number of parts. Furthermore, the assembly work is extremely simple because the locking member can be assembled simply by pushing and locking the locking member into the guide groove provided in the locking member holding plate.

In particular, the locking device of the present invention is extremely advantageous when applied to containers that are to be installed in restricted locations, since the locking device is locked inside the container and has almost no protruding portion to the outside of the container.

For example, in the case where two storage sections are arranged side by side as in the above-mentioned console box, the locking device does not protrude from the lid of the first storage section, so the second storage section can be used extremely effectively. I can do it.

Also. The fact that the locking device does not protrude is superior in terms of safety, and also provides a clean appearance of the container, which is also excellent in design.
