Description

[Detailed Description of the Invention] This invention relates to an opening/closing lid of a storage box for storing small items, such as a console box of an automobile.

Conventionally, in this type of box, the opening/closing lid is pivoted to the box body via a hinge so that it can be opened and closed.

In this case, in order to bias the opening/closing lid in one direction, for example, in the opening direction, a torsion spring may be inserted into the hinge, but the opening/closing lid is made of a thin-walled hinge (so-called P, P hinge). In the case where the torsion spring is pivotally mounted, it is impossible to insert a torsion spring as described above, and there is a drawback that it becomes difficult to bias the torsion spring.

Therefore, the present invention has been devised so that even when the opening/closing lid is pivoted by a thin hinge, it can be easily biased in one direction by simply adding a torsion spring, just like when the opening/closing lid is pivoted by a hinge. This is what I did.

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

1 and 2 show an embodiment in which the present invention is applied to a console box mounted on the floor of an automobile.

In the figure, 1 is a box body forming an accessory storage chamber 1a, and 2 is an opening/closing lid that covers an opening 1b of the box body 1, and this opening/closing lid 2 is formed of an outer 2a and an inner 2b made of synthetic resin. The inner 2b has a bendable hinge piece 2c with a thin part 2c formed by, for example, a striped notch, and the hinge piece 2c is screwed to the back side of the opening 1b of the box body 1. has been done.

Therefore, the opening/closing lid 2 can be opened and closed by a thin hinge (so-called P, P hinge) formed by the hinge piece 2c.

3 is a stay attached to the top end of the opening/closing lid 2;
passes through a hole 1c provided in the opening 1b of the box body 1, and has a stopper portion at its lower end that engages with the hole 1c to prevent the opening/closing lid 2 from opening beyond a predetermined opening degree.

Reference numeral 4 denotes a torsion spring formed in a U-shape, the horizontal part of which is supported by a retaining plate 5 screwed together with the hinge piece 2c on the back surface of the opening 1b of the box body 1, and The lower end is engaged with the box body 1, and the other leg portion 4b is engaged with the lower end of the stay 3.

The torsion spring 4 is configured to press the stay 3 in the opening direction due to its torsional stress when the opening/closing lid 2 is closed, thereby biasing the opening/closing lid 2 in the opening direction.

Further, the torsion spring 4 is arranged so that its horizontal portion is as close as possible to the hinge portion to reduce the relative displacement between the leg portion 4b and the stay 3 when the lid 2 is opened and closed.

With the above configuration, by simply adding the torsion spring 4 and releasing the locking device (not shown) of the opening/closing lid 2, the opening/closing lid 2, which is pivoted by the thin-walled hinge, is biased from the fully closed position and becomes light. can be opened.

In the above embodiment, the opening/closing lid 2 is biased in the opening direction, but it can also be biased in the closing direction.

As explained above, according to the present invention, a torsion spring is used as a spring means for biasing the opening/closing lid pivotally connected by a thin hinge in one direction, and this torsion spring is used as a spring means for biasing the opening/closing lid between the box body and the opening/closing lid. Since the torsion spring is engaged with the stay, even when the opening/closing lid is fully opened, the torsion spring will not protrude above the opening of the box body. Therefore, even if a torsion spring is added, the thin hinge There is no need to cut out a part of the hinge or narrow the width, and there is no adverse effect such as damage to the hinge.

In addition, the above-mentioned tritortion spring does not protrude above the opening of the box body, and the hinge piece with the thin hinge can be fixed to the opening, so that the fixing screws etc. can be fixed to the box body. It is not exposed on the side of the main unit.

Furthermore, the present invention is an extremely useful invention that has various effects such as the space occupied by the torsion spring being small and the structure being simple, in addition to the above-mentioned effects.

Claims (1)

[Scope of utility model registration request] In a storage box in which a synthetic resin opening/closing lid is pivotably opened and closed via a thin hinge integrated with the opening/closing lid, a torsion spring is provided near the opening/closing lid of the storage box with its horizontal portion extending along the thin hinge. The torsion spring is arranged and supported, one end of the torsion spring is engaged with the storage box body, and the other end is engaged with a stay protruding from the opening/closing lid, thereby biasing the opening/closing lid in one direction. Box opening/closing lid.
