Description

[Detailed description of the invention] This invention relates to a storage box for storing articles.The purpose of this invention is to be able to hold the lid at a predetermined opening angle with respect to the box body, and to be able to open and close the lid with ease. To provide a storage box which can be provided with the following properties, has a simple structure, and can reduce costs.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 indicates the entire storage box, which is composed of a box body 2 and a lid 3.

The box body 2 is made of synthetic resin and is formed in the shape of a bottomed rectangular box with an upward opening, and left and right surface engaging protrusions 4, 4 are integrally provided on the negative side upper surface thereof.

These surface engaging protrusions 4, 4 are formed to be elastically deformable, and a locking surface 5 having a semicircular arc as shown in the drawing is formed at the upper end thereof.

Further, on the edge of the upper surface of one side of the box body 2, a support wall plate 6 is elastically deformable for pressing the opening/closing pivot side of the lid 3 and biasing it in the opening/closing direction when the lid 3 is opened/closed. It is erected in one piece.

On the other hand, the lid body 3 for covering the opening of the box body 2 is made of a synthetic resin such as polypropylene with high strength, and is attached to the box body by three hinges 7 to 7 integrally formed on the negative side of the lid body 3. 2 so that it can be opened and closed.

That is, the hinges 7 to 7 are formed in a cross-sectional shape,
The horizontal pieces 8 are each fastened to the upper surface of one side of the box body 2 by screws 11, and a vertical piece 9 is formed along the inside of the support wall plate 6 and at the upper end of the vertical piece 9. It is integrally formed on one side of the lid body 3 via a bendable thin-walled bending part 10.

Further, on the side edge of the lid 3 on the opening/closing pivot side, an engagement member is provided that detachably engages with the surface-engaging protrusion 4.4 to hold the lid 3 at a predetermined opening angle. Branch lines 12, 12 are each formed integrally.

These engaging branch lines 12, 12 are perpendicular to the lid surface of the lid body 3, and when the lid body 3 is opened at a predetermined angle, the locking surfaces 5, 5 formed on the surface engaging protrusions 4, 4, It has a length that can be engaged with the arcuate upper surface of No. 5 in an abutting manner.

Furthermore, when the lid body 3 is opened, both the engaging supporting edges 12, 12
The distal end portion 13° 13 is formed in an arc shape so as not to be recessed into the surface engaging protrusions 4, 4.

Subsequently, the operation of this embodiment configured as described above will be explained.

First, in the closed state of the lid body 3 in which the bent portion 10 of the hinge 7 is bent at a right angle as shown in FIG. Tip of 12 13.13
are spaced apart as shown in Figure 2A.

Next, when the lid 3 is moved to open relative to the box body 2 in the direction of arrow P in FIG. Since the corner portion 14 between the lid body 3 and the engagement ridge 12 is pressed against the engagement surface 5 and the support wall plate 6, the engagement protrusion 4 and the support wall plate 6 are each elastically deformed. It bends.

At this time, stress is applied to the hinge 7 due to the repulsive force of the engaging projecting piece 4, but since the vertical piece 9 of the hinge 7 is supported by the support wall plate 6, damage to the hinge 7 is actively prevented. be able to.

Thereafter, when the lid body 3 is moved to open against the clamping force between the locking protrusion 4 and the supporting wall plate 6, the retaining friction force generated between the engagement protrusion 4 and the engagement ridge 12 is The pressing force due to the elastic restoring force of the support wall plate 6 increases, and after that, the corner 14 of the lid 3 is pushed out by the elastic restoring force of the support wall plate 6, and the lid 3 is moved to the second position.
As shown in FIG.
Since the tip 13 of the engaging raised edge 12 is engaged in abutting manner with the arcuate upper end surface of the lid 3, the lid 3 is not closed by its own weight and is held at a predetermined opening angle. Ru.

Moreover, when closing the lid body 3, it can be closed by an operation opposite to the above.

Note that the engagement surface 5 of the engagement protrusion 4 may be formed in a step shape as shown in FIG. 4, or may be formed in a multi-step shape as shown in FIG.

In this case, the lid 3 can be held open at two or more open positions.

In the present invention, an engaging protrusion is curved on the upper surface of one side of the box body, and the engaging protrusion is removably engaged with the opening/closing pivot portion of the lid body to hold the lid in a predetermined position. An engaging raised edge is formed to hold the box at an opening angle of .
Since this storage box is provided with an elastically deformable support wall plate that presses the opening/closing pivot portion side of the lid body and biases it in the opening/closing direction when the lid body is opened or closed, the engagement protrusion of the box body On the other hand, the lid can be held at a predetermined opening angle by engaging the engagement ridges of the lid in an abutting manner.

Furthermore, when the lid is opened and closed, the supporting wall plate presses the opening/closing pivot side of the lid to urge the lid in the opening/closing direction, so that a sense of moderation can be imparted to the opening and closing of the lid.

Moreover, since the structure is extremely simple, it is also possible to reduce costs.
