Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a hinge structure that connects a lid and a main body.

``Prior Art'' It is convenient in terms of operation to be able to open and close caps attached to the mouthpiece of containers, lids, etc. attached to the bodies of compact containers with a single touch.

Therefore, for example, a method is used in which a torsion spring is attached to a hinge portion that connects the main body and the lid.

That is, the closure of the lid is ensured by locking the ends of the main body and the lid, and when the locks are released, the torsion spring, whose both ends are in elastic contact with the main body and the lid, is unwound. The force acts as an opening force and opens the lid.

With this configuration, the lid can be opened by simply releasing the lock, and the lid can be locked by simply closing the lid, making it extremely easy to handle.

``Problem that the invention aims to solve'' However, in this case, when connecting the main body and the lid with a hinge, a torsion spring must be attached at the same time, and the torsion spring is elastically deformed in the direction in which the coil is wound. Since the main body and the lid have to be brought into elastic contact with each other and assembled, the work is extremely time-consuming.

As a solution to this dissatisfaction,
As shown in Japanese Patent No. 192580, a structure in which a torsion spring is temporarily attached to a hinge piece of a cylindrical lid body has been proposed, but this Utility Model Application Publication No. 1983-
The torsion spring assembly structure shown in Publication No. 192580 is
Since the other extended end of the torsion spring that comes into elastic contact with the main body side is located at the other open end of the hinge piece, the end of the torsion spring connected with this other extended end protrudes outside the hinge piece. Therefore, when the torsion spring is elastically deformed, the torsion spring alone cannot appropriately achieve the elastic deformation form of the protruding end of the torsion spring.
Since there is a high risk of improper deformation, it has been necessary to provide a structure in which the torsion spring is externally mounted on the hinge shaft in order to regulate the elastic deformation form of the torsion spring to a constant level.

For this reason, in the case of a conventional hinge structure in which a torsion spring is assembled, it is necessary to have a structure in which the torsion spring is externally mounted on the hinge shaft, which poses the problem that it can only be applied to a structure that uses a single hinge shaft. Ta.

Therefore, the present invention was devised to solve the above-mentioned problems in the conventional technology, and the technical problem was to assemble a torsion spring into a hinge structure independently of the hinge shaft. The purpose is to simplify the built-in hinge structure and to simplify the work of assembling this hinge structure.

"Means to solve problems" The configuration of the present invention will be explained below with reference to the drawings.

The present invention is composed of a main body 1, a lid 14 that is fitted into the upper end of the main body 1 so as to be openable and closable, and a torsion spring 27 that is installed between the lid 14 and the main body 1.

A recess 5 that is open from above to the rear is provided on the upper surface of the rear end of the main body 1, and a hinge piece 1 hanging down from the lower surface of the rear end of the lid body 14 is inserted into the recess 5.
6 is fitted and supported.

This hinge piece 16 has a cylindrical shape, and a notch groove 21 is provided in the lower cylinder wall portion 18 along the length direction, and a locking recess 2 is provided at one end inside the hinge piece 16.
2 is provided, and a notch fitting groove 23 is provided at the other end of the hinge piece 16 in succession to the notch groove 21.

Additionally, a torsion spring 27 incorporated into the hinge piece 16
The other end is inserted into the notch groove 21 and inserted into the cylindrical hinge piece 16, one end is locked in the locking recess 22, and the other end is inserted into the notch fitting groove 23. It is inserted into the main body 1 and comes into elastic contact with the locking part 7 of the recess 5 of the main body 1.

"Operation" In the above-described configuration, the torsion spring 27 is fitted into the cylindrical hinge piece 16, one end of which is engaged with the locking recess 22, and the other end of which is engaged with the notch fitting groove 23. Since the hinge piece 16 is held in this holding position, it is sufficient to fit the hinge piece 16 into the recess 5 of the main body 1 and pivotally support it.

In this case, the other end of the torsion spring 27 protruding from the notch insertion groove 23 is elastically deformed in the winding direction of the torsion spring 27 when the lid body 14 is in the closed position, so as to come into elastic contact with the locking part 7 of the recess 5. Therefore, the lid body 14 is always biased in the opening direction.

Further, the torsion spring 27 is entirely connected to the hinge piece 16.
Since it is inserted and assembled inside, its elastic deformation form is constantly and stably regulated to an appropriate form by the hinge piece 16, so that it always performs stable and constant elastic deformation. Become.

In this way, the torsion spring 27, which has been completely inserted and assembled into the hinge piece 16, has its elastic deformation properly regulated by the hinge piece 16, and therefore, in order to keep the elastic deformation constant, the torsion spring 27 is attached to the hinge shaft. There is no need to combine them at all.
