Description

[Detailed explanation of the idea] The present invention relates to a hinge.

Conventional hinges that connect two parts so that they can be opened and closed, but can be stopped at any opening angle, include those that have the ends of two metal plates bent into a cylindrical shape and tightly penetrate the shaft, and hinges that can be stopped at any opening angle. There are types in which a spring pin made of a metal plate bent into a cylindrical shape is inserted, and types in which a disc-shaped metal spring or elastic material such as rubber is interposed between the opposing surfaces of two parts that pass through the shaft. . According to the first and second examples, since the metal plate is difficult to bend and cannot be finished uniformly, the friction torque on the outer circumferential surface of the shaft or spring pin becomes uneven between the center and both ends, and the amount of tightening on one side becomes uneven. This has the disadvantage that the other one will not work. According to the third example, the number of parts is large, and since the elastic force is applied in the axial direction, it is difficult to obtain a large friction torque, and there are problems with durability with rubber, etc. In either case, there are various disadvantages. It was hot.

The present invention eliminates the above-mentioned drawbacks of the conventional method, and by tightly press-fitting one part and connecting it non-rotatably, and making it possible to slide on the other part, the friction torque of one sliding part is reduced. To provide a hinge that facilitates torque setting and management, has a small number of parts, is simple in structure, and easy to assemble and disassemble.

In the first and second illustrations, 1 and 2 are two parts that are swingably connected. Bearing holes 3, 3 are provided back to back along the same axis at one end of one component 1, and a female screw hole 4 is provided at the bottom of the bearing holes 3, 3 along the same axis. be. The other part 2 has sliding holes 5, 5 formed opposite to the bearing holes 3, 3 and having a larger diameter than the bearing holes 3, 3. Reference numerals 6 and 6 denote sliding bodies, which are made of synthetic resin in this example, and are fitted into the bearing hole 3 and the sliding hole 5.
7, 7 are decorative screws, and the male threaded portions 8, 8 at the tips are decorative screws.
is screwed together with the female screw hole 4.

As shown in FIGS. 3 and 4, one end of the sliding body 6 (the left end in FIG. 3) is a press-fitting part 6a with a circular outer peripheral surface that is tightly press-fitted into the shaft hole 3, and the other end is a press-fitting part 6a that is tightly press-fitted into the shaft hole 3. 5
This is a slip portion 6b that can be slid between. Although the shaft center portion is a hollow shaft center portion 9, the press-fit portion 6a does not need to be hollow, and a cylindrical portion may be provided with a certain length. A cut groove 10 is formed in the axial direction from the slip portion 6b to a part of the press-fit portion 6a. The slip torque of the slip portion 6b is set depending on the gap, length, and wall thickness of the cut groove 10.

When assembling, first align the bearing holes 3 and sliding holes 5 of parts 1 and 2 on the same axis,
One sliding body 6 is inserted from the press-fitting part 6a.
Since the press-fit portion 6a is tightly press-fit into the bearing hole 3,
The sliding body 6 and the component 1 are non-rotatably connected. Furthermore, the space between the slip portion 6b and the sliding hole 5 of the component 2 is compressed radially inward by the groove 10 and expands radially outward, so that the outer circumferential surface of the slip portion 6b and the sliding hole 5 are It is slidable between the inner peripheral surface and the inner peripheral surface.
When the shaft center part is a hollow shaft center part 9, by screwing the decorative screw 7 into the male screw hole 8 and the female screw hole 4, the space in the shaft center is covered, resulting in a good appearance. The other sliding body 6 is also press-fitted in the same manner.

5 to 8 show other examples, in which the sliding body 16 has a press-fit part 16a at the center and slip parts 1 at both ends.
6b and 16b. The kerfs 20, 20 are cut from both ends toward the center, and the center is not cylindrical but has a cylindrical portion 16c so that the axial center is not hollow. In this example, since the outer diameter of the press-fit portion 16a is large, a bearing plate 12a is connected to the other component 12 with screws 21, and a sliding hole 15 is formed in this bearing plate.

Therefore, when assembling, first parts 12
One of the bearing plates 12a is fixed with screws 21.
Next, one opening of the bearing hole 13 of the component 11 and the sliding hole 15 are made to face each other, and the sliding body 16 is inserted from the other opening of the bearing hole 13. Since the press-fitting part 16a is tightly press-fitted into the bearing hole 13, the sliding body 16 and the component 11 are connected in a non-rotatable manner, and at the same time, the slip part 16b is fitted into the sliding hole 15. Next, insert the sliding hole 15 of the other bearing plate 12a into the other slip portion 1.
6b, and attach the bearing plate 12a to the part 12 with screws 2.
Fixed at 1. Thereby, the slip portions 16b, 16b of the sliding body 16 and the sliding holes 15, 15 are slidably connected by being compressed and expanded in the radial direction by the grooves 20.

Note that the cylindrical portion 16c makes the press-fitting state of the press-fitting portion 16c tighter and more stable.

When parts 1 and 2 or 11 and 12 are opened and closed,
Since the sliding body 6 or 16 and the parts 1, 11 cannot rotate, opening and closing are performed by sliding between the sliding body 6, 16 and the parts 2, 12. The setting of the slip torque for stably stopping at a desired opening angle is based on the slip portions 6b, 1 with respect to the inner diameter of the sliding holes 5, 15.
It can be easily set by selecting the outer diameter dimension of 6b, its wall thickness, the width and length of the cut grooves 10 and 20, etc.

In this way, according to the present invention, it is easy to set and manage the slip torque, it is possible to stably stop at the desired opening angle, the number of parts is small,
The structure is simple, and assembly and disassembly are easy. In addition, the press-fit portion has no grooves and maintains the outer peripheral shape of the circumferential surface, so the shaft center position does not move and it is easy to determine the center of oscillation of both parts.
