Description

[Detailed description of the invention] <Industrial application field> This invention is used for closing boxes that hold closed lids that close the boxes or box-like spaces of automobile console boxes, TVs, videos, and other products. Relating to a lid device.

<Prior Art> Conventional lids made of sheet metal or plastic have an elastic piece formed integrally with the lid, which elastically engages with a hole or recess formed in the edge of a box when the lid is closed.

<Problems that the invention aims to solve> When forming the lid with sheet metal, it is necessary to cut an elastic piece from the lid and bend it into a folded shape, which is extremely time-consuming. In the case of molding, the mold becomes very complicated in order to form the elastic piece, and in any case, the cost of the lid increases.

<Means for solving the problem> Therefore, the present invention consists of a box A and a lid B for opening and closing the opening of the box, and a hole 8 is formed in the edge of the free end of the lid B. At least one pair of opposing pieces 3 and 4 sandwiching the mounting piece, and a base body 2 having a protrusion 6 provided on one of the opposing surfaces of the opposing pieces, and one end connected to the base body. and a clip 1 made of plastic and having an elastic piece 5 that elastically engages the edge or recess of the box body at its other end when the opening of the box body A is closed with the lid B; The mounting piece b of the lid is sandwiched between the opposing pieces 3 and 4, and the hole 8 of the mounting piece is inserted into the convex portion 6.

<Example> In each of the illustrated examples, A is a box, B is a lid for opening and closing the opening, and 1 is a clip integrally molded from plastic. It includes a U-shaped or cylindrical base body 2, an elastic piece 5, and a convex portion 6.

In the embodiment shown in FIGS. 1 to 5, the lid B is integrally formed of plastic, connected by a thin hinge 7 along the open lower edge of the box body A, which is a console box, and the upper edge of the lid B is the free end side. A mounting piece b having a hole 8 is provided at right angles to the part. To increase the strength of mounting piece b, mounting piece b has triangular reinforcing walls 9 on both sides.
It connects and grows from lid B.

The base body 2 of the clip 1 is approximately U-shaped in this embodiment, and the U-shaped elastic piece 5 has one end connected to the facing piece 4, and the convex portion 6 is formed on the surface of the facing piece 3 facing the facing piece 4. It is formed into a sawtooth shape.

As a result, when the U-shaped base body 2 is embedded and covered with the mounting piece b as shown by the arrow in FIG. 1, the opposing pieces 3 and 4 will pinch the mounting piece b as shown in FIG. When the clip 1 enters the hole 8 and attempts to pull out the clip 1 from the mounting piece b in the opposite direction, the convex portion 6 catches on the edge of the hole 8 and prevents the clip from being pulled out.

In this state, when the lid B is raised upward around the hinge 7, the bent part of the elastic piece 5 elastically enters and gets caught in the recess a, which is a hole, provided at the edge of the upper surface of the box body A. Keep lid B closed.

To open box A, apply a little force and pull lid B toward you. As a result, the elastic piece 5 is bent and removed from the recess a, and the lid falls forward to open the box A.

As clearly shown in FIG. 4, the opposing piece 4 has a curved portion 4' bent in the same direction as the protruding direction of the protruding portion 6 at a position facing the protruding portion 6 of the opposing piece 3. be.
This makes it possible to prevent the formation of partially thin weakened parts on the wall of the mold for forming the opposing pieces 3 and 4 apart.

In the embodiment shown in Figures 6 to 10, both the box body A and the lid B are made of sheet metal, and the lid B is separated from the box A, and in order to close the open part of the box A, the lid is closed as shown by the broken line in Figure 6. Insert one end of the lid, which is bent into a step shape at an angle, into one end of the open part of the box, and using this as a fulcrum, lower the other end of the lid as shown by the arrow and fit it into the open part of the box.

Therefore, a mounting piece b having a hole 8 is formed at the other end of the lid by bending it at a right angle.

In this embodiment, the pair of opposing pieces 3 and 4 are continuous on both side walls 2' of the base body 2. Therefore, the base body 2 has a flat cylindrical shape, and the spacing between the opposing pieces 3 and 4 is vertically open.

The elastic piece 5 has one end connected to the opposing piece 4 and extends obliquely, and has two protrusions 5' provided on the outer surface of the upper end for engaging the edge of the other end of the open part of the box A.

Further, the convex portion 6 that protrudes into the hole 8 of the mounting piece b is formed as a part of a spherical surface on the surface of the facing piece 3 that faces the facing piece 4.

Therefore, when the cylindrical base body 2 is pushed around the mounting piece b of the lid, the mounting piece b is pressed between the opposing pieces 3 and 4, and the convex portion 6 projects into the hole 8 of the mounting piece. Then, as described above, when the lid B is attached to the open part of the box and the open part is closed, the elastic piece 5 is bent, and the protrusion 5' on the outer surface of the free end of the elastic piece 5 is bent.
5' grips the edge of the open part of the box to hold the lid closed.

To open the opening/closing part of the box from this state, push the free end of the elastic piece 5 toward the base 2, and the protrusion 5',
5' away from the edge of the box and operate in the opposite direction to closing.

In this embodiment as well, since a thin fragile part is not formed in the wall of the mold that separates both facing pieces 3 and 4, the facing piece 4 is
Projections 10 and 1 are provided in the vertical direction apart from each other on both sides of the convex portion 6.
0 is set protrudingly. Therefore, the mounting piece b is the opposite piece 4.
It is actually squeezed between the protrusions 10, 10 and the opposing piece 3.

Note that a hole 4' of the same size is formed in the facing piece 4 at a location that coincides with the convex part 6 of the facing piece 3, but this hole 4' is formed using a mold for molding the convex part 6 as part of a spherical surface. It was created to allow the core to pass through, and has nothing to do with the function of the clip.

<Effects of the invention> As described above, in the present invention, a mounting piece with a hole is provided on the free end side of the lid, and the mounting piece is mounted using U-shaped or cylindrical opposing pieces of the plastic clip base. The clip can be easily attached to the lid by pinching, and the lid can be held closed by the elastic piece provided integrally with the clip.

This greatly facilitates the molding of the lid, since it is only necessary to provide the lid with a mounting piece having holes in the edge.
