Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to an improvement in a storage box with a lid that is integrally installed via a plastic hinge.

For example, in the case of automobile glove boxes, console boxes, and other small items boxes,
In order to facilitate its manufacture, it is well known that a container is integrally formed between the front and side edges of the box via a plastic hinge.

The plastic hinge is a thin groove-shaped part formed on the joining edge of the box and the lid, and this part has the function of a hinge. Compared to other products, the number of parts is reduced and it is made in one piece, making it extremely cheap +11
It can be manufactured to 1i and has extremely high durability.

However, on the other hand, since the plastic hinge itself has a certain degree of rebound elasticity, the opening/closing end of the lid may float away from the box-L when the lid is closed. In order to tighten it properly, a locking mechanism must be provided at the opening and closing ends.

In addition, with such a plastic hinge, when the lid is opened, the opening position (maximum opening angle of the lid with respect to the box) is not determined.
If it is desired to set the opening degree to a certain angle in this way, a mechanism for regulating the opening angle must be separately provided, which will cause the effective volume inside the box to be reduced.

(Object of the Invention) This invention makes it possible to integrally mold a means for regulating the opening/closing angle of the lid in the above-mentioned storage box integrated with a plastic hinge, thereby making it possible to integrally mold a means for regulating the opening/closing angle of the lid. This is an attempt to simplify the process.

(Configuration and Effects of the Invention) In order to achieve the above object, the present invention provides a lid comprising a box with an opening on one side and a lid that is openably and closably joined to the opening edge and side of the box via a plastic hinge. In the storage box with a storage box, a notch is formed at an appropriate position on the joining edge between the box and the lid, and a tension piece is provided in the center of the notch, one end of which is integrated with the box and the other end of which is integrated with the lid. Features.

According to the above structure, the tension piece has stable points respectively when the lid is closed with respect to the box and at a position opened at a certain angle, thereby automatically locking when the lid is closed and adjusting the opening angle when opening the lid. According to the present invention, these mechanisms can be realized without using any other mechanical parts, so there is an advantage that the mechanisms are further simplified.

(Description of Embodiment) FIGS. 1 and 2 show an embodiment of a box to which the present invention is applied.

The lid-side storage box in each figure is made of an injection molded body of polypropylene or the like, and includes a box 1 with an opening on the - side,
The box 1 has an M2 molded on the side edge of the opening so that it can be opened and closed via a plastic hinge 3, and the outer periphery of the lid 2 is designed to cover the outer periphery of the opening of the box 1. An overlap margin 2a having a larger diameter is formed.

At the center of the joint edge between this box 1 and the lid 2, there is a notch 4,
4 is notched, and each notch 4.4 is formed with a notch.
A tension piece 5, which curves inward when M2 is in the closed state, is formed in the center of the box 1, with its both ends integrally joined to the lid 2 and the box 1.

The tension piece 5 is formed thinner than the thickness of each of the box 1 and the lid 2, and is curved so that it can be expanded and contracted by external force.

However, in the storage box with a lid configured as described above, when the lid 2 is closed, the tension piece 5
No tension is applied to the lid 2, and the lid 2 is in a stable position.

When attempting to open the lid 2 from this state by turning it around the plastic hinge 3, the actual rotation locus at the lid side end 5a of the tension piece 5 is as shown in FIG. A △-like trajectory is drawn with the hinge portion 3 as the base point.

On the other hand, when the tension piece 5 is rotated using the point 51 on the box side as a base point, the rotation locus is as shown in B.

Therefore, the difference (8-B) between the rotation trajectories is the tension generated in the tension piece 5 (the shaded portion in the figure).

Further, at the point where the respective rotation trajectories match, that is, the point C1C5-1, the tension becomes O, and the lid 2 is in a closed position and a state in which it has been rotated to a certain position.

In other words, with the lid 2 closed, the box 1
This is the point at which the position is fixed in a state where it is opened by a certain rotation angle.

In other words, the storage box with a lid configured as described above has two stable points, one in the closed position and the other in the position in which the lid 2 is opened at a certain rotation angle. Thus, the lid 2 has the functions of both locking in the closed position and regulating the opening degree. You can also feel a click when opening and closing, giving you a good operating feel.

In the above embodiment, the box and the lid are formed into an appropriate rectangular shape, but they can be formed into any shape, and can be used for various purposes such as glove boxes, console boxes, and other small objects. Needless to say, it can be formed into any shape.
