Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hinge mechanism for a compact case having a lid that can be opened and closed.

[Conventional technology]

Conventionally, compact cases have had a structure in which the container housing the cosmetics and the lid are hinged together so that they can be opened and closed freely, and a locking mechanism has been provided to hold the lid in the closed state. . In this locking mechanism, a hook is hung from the lid, and the hook is engaged with the container to hold the lid in a closed state.

[The problem that the idea attempts to solve]

However, in this type of structure, the hook engages with a concave or convex portion provided in the vessel body by pushing into or overcoming it, which is accompanied by elastic deformation of the hook. Therefore, the engagement strength between the lid and the container changes significantly due to variations in the dimensions of the container and the lid, or the hook, etc., and the feeling of unlocking the lid differs from one product to another. It was hot. Therefore,
It was nearly impossible to uniformize the engagement strength to the optimum level.

[Means to solve problems]

Hinge parts are provided at the ends of the container body 1 and the lid body 7 that house the cosmetics 2, and each hinge part is connected to the shaft 10.
In the structure in which the container body 1 and the lid body 7 are connected to each other so as to be openable and closable by being supported by a penetrating shaft, one hinge part has a recess 5 in the center so that the other hinge part is placed between them. establish. A through hole 13 having a larger diameter than the outer diameter of the shaft 10 to be penetrated is bored in the hinge portion located at the center. The shaft 10 has both ends fixed to hinge parts disposed on both sides, and has an elasticity of the through hole 13 to tightly fit the shaft 10.
Wrap the ring 14 around it. High viscosity oil 15 is sealed between the O-rings 14. The present invention has the above structure.

[Effect]

When the lid body 7 is opened and closed, an appropriate resistance is generated due to the frictional resistance of the O-ring 14, which is in close contact with one of the hinges and lubricated by the oil 15, and the viscous resistance of the oil 15, providing a good operating feeling. You can get it. Moreover, the variation in the dimensions of the lid body 7 and the vessel body 1 is as follows:
This is absorbed by the O-ring 14 being elastically deformed.

〔Example〕

The container body 1 has a cosmetic storage space 4 engraved on its upper surface for storing an inner tray 3 filled with cosmetics 2. A pair of container-side hinge portions 6 are provided on both sides of the rear end of the container body 1, and a recess 5 is formed in the center.

The lid body 7 has a mirror 8 attached to its back surface, and a lid side hinge part 9 disposed in the recess 5 between the container side hinge parts 6 at the rear end. A shaft 10 passes through the lid-side hinge portion 9 and the container-side hinge portion 6, forming a hinge 11 that connects the container body 1 and the lid body 7 in an openable and closable manner.

A through hole 13 is bored in the lid side hinge part 9.

Further, the shaft 10 is fixed at both ends to the container-side hinge portion 6, and the portion that passes through the through hole 13 of the lid-side hinge portion 9 between the container-side hinge portions 6 is a shaft support portion whose diameter is reduced. 12, so that a gap is created within the through hole 13. An O-ring 14 is wound around both ends of the shaft support 12, and the O-ring 14 is elastically attached to the inner wall of the through hole 13 of the lid-side hinge portion 6. A high viscosity oil 15 is placed in the gap between the O rings 14.
is included. As a result, the lid-side hinge portion 9 is pivotally supported by the shaft 10 via an O-ring 14 and oil 15. The lid body 7 can be rotated, that is, opened and closed using oil 15 as a lubricant.

Further, a hook 16 hangs down from the tip of the back surface of the lid 7, and a locking mechanism 17 that locks the hook 16 and holds the lid in a closed state is attached to the tip of the container 1.
has been established.

In addition, in the embodiment of the present invention, the container side hinge part 6 of the container body 1
A recess 5 is provided in between, and an O-ring 14 and oil 15 are installed in the lid-side hinge part 9 of the lid body 7, but in other words, the lid-side hinge part 9 is placed on both sides of the rear end, and the The recess 5 is configured, and the container side hinge part 6 is connected to the lid side hinge part 9.
This container side hinge part 6
It is also possible to have a structure in which an O-ring 14 and oil 15 are installed inside.

[Effect of idea]

As described above, the present invention solves uneven engagement strength between the hook 16 of the lid body 7 and the locking mechanism 17 due to variations in the dimensions of the components of the compact case. It is absorbed by elastic deformation, and the engagement strength of the lid body 7 can be made uniform.

Furthermore, when opening and closing the lid body 7, the frictional resistance of the O-rings 14 causes an uncomfortable opening/closing feeling, but the viscous resistance of the oil 15 sealed between the O-rings 14 and the ring 14
The unpleasant operating feeling is eliminated and the operating feeling is adjusted to have appropriate resistance.

Note that since the oil 15 is sealed at both ends by the O-ring 14, the oil 15
5 will not leak outside and contaminate the surrounding area.
