Abstract

The present invention relates to a hinge device, and more particularly, to a hinge device that can continuously and accurately control the opening operation by improving the lubricity of the hinge device. As a general example, the hinge is used to connect the main body and the cover of a portable computer, a mobile phone, etc., so that the cover is used as an appropriate stop means for maintaining a constant angle around the hinge device.

The hinge device of the prior art inserts a lubricant to prevent wear due to friction of the washer portion. However, there is a problem that wear of the friction part occurs due to the limitation of the lubricant applied during long-term use.

Description

Flat Washer for Hinge System {Plane Washer}

The present invention relates to a hinge device, and more particularly, to a hinge device that can continuously and accurately control the opening operation by improving the lubricity of the hinge device. Looking at an example of the hinge device of the prior art, the shaft of the hinge device is equipped with a plurality of cylindrical or disc springs to impart a friction force to the adjacent member by a predetermined elasticity to maintain a fixed angle of the open cover, and A plurality of flat washers is mounted to allow rotation of the hinge shaft.

However, in the prior art, a plurality of flat washers are coated with a lubricant to prevent abrasion due to friction when the shaft is rotated together with the shaft. Had a problem.

The present invention has been made to solve the various problems of the prior art as described above, an object of the present invention is to provide a hinge washer flat washer that can smooth the damage and the shaft caused by the friction of the flat washer in the long-term use of the hinge To provide.

A feature of the present invention for achieving the above object is that the shaft hole is formed so that the shaft can be inserted through the center, and an oval hole is formed around the hole to contain a large amount of lubricant, It is a flat washer for the hinge device to prevent friction and smooth rotation of the shaft.

Hereinafter, a preferred embodiment of a flat washer for a hinge device according to the present invention will be described in detail with reference to the accompanying drawings.

1 to 7 are diagrams for explaining the flat washer for the hinge device according to the present invention.

First, referring to FIG. 1, the hinge device of the present invention includes a bracket 11 having a shaft hole 20 formed at one side of a shaft 10, and a football between the shaft 10 and the bracket 11. A plurality of flat washers 13 and a plurality of disk washers 14 in which a yoke 20 is formed are fitted and fastened by nuts 15.

The spring 17 is fastened between the plates 18 and 19 to form an elastic portion. The plate 18 has a locking jaw 22 to be rotated only at an arbitrary angle by the stopper 21 formed on the bracket 11.

2 and 3, when the bracket 11 rotates together with the shaft 10, a torque is generated by the spring 17, and a friction force is generated by the disc washer 14, and only by a constant force. The shaft 10 rotates. The bracket 11 is fixedly coupled to a coupling hole formed in, for example, a TFT LCD monitor cover to which the hinge device of the present application is applied.

4 and 5, the flat washer 13 has an elliptical hole 30 formed outwardly from the face 32 and the shaft hole 20 and an elliptical hole 31 formed outwardly from the shaft hole 20. A large amount of lubricant is applied to maintain wear and smooth rotation of the shaft 10. Although three oval holes 30 and 31 are shown in the figure, they may be appropriately changed as necessary.

6 and 7, in the prior art, a hole 40 or a pinwheel-shaped hole 41 is formed to contain a lubricant, but in the case of the hole 40, the content of the lubricant is small, and a pinwheel-shaped hole 41 is formed. ) Is not fully lubricated because it is concentrated in the center.

The embodiments described above are merely illustrative of one embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and may be appropriately changed within the claims. For example, the shape and structure of each component specifically shown in the embodiment of the present invention can be modified.

As described above, according to the hinge device according to the present invention, wear of the flat washer is reduced by friction, and smooth operation of the shaft improves the operability and durability of the hinge device.

Claims (1)

A shaft hole 20 through which the shaft 10 penetrates and rotates is formed at the center of the flat washer 13, and an elliptical hole 30 formed outwardly from the shaft hole 20 and an ellipse toward the shaft hole 20 from the outside are formed. A flat washer for a hinge device, characterized in that a hole (31) is formed to contain a large amount of lubricant.
