Description

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

Conventional hinges that connect two parts in a swingable manner that can be stopped at any opening angle include those that have two metal plate parts bent into a cylindrical shape with the ends tightly passed through the shaft, and a hinge that can be stopped at any opening angle. There are those in which a spring pin made of a metal plate bent into a cylindrical shape is inserted into the shaft, and those in which a disc-shaped metal spring or elastic material such as rubber is interposed between the opposing surfaces of two parts that penetrate the shaft. be. 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 conventional drawbacks, provides a sliding body that cannot rotate with one part and can slide with the other part, and manages the friction torque of one sliding part. It is easy to set up and manage, has a small number of parts, is easy to configure, and is easy to assemble and manage.
This provides a hinge that is easy to 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. A groove 5 is formed in a part of the inner peripheral surface of the bearing holes 3, 3 in the axial direction as a rotation stopper. The other part 2 has sliding holes 6, 6 formed opposite to the bearing holes 3, 3 and having a larger diameter than the bearing holes 3, 3. Reference numerals 7 and 7 are sliding bodies, which in this example are made of synthetic resin, and which are connected to the bearing hole 3.
and is fitted into the sliding hole 6. Reference numerals 8, 8 are decorative screws, and the male threaded portions 9, 9 at the tips are screwed into the female threaded hole 4.

As shown in FIGS. 3 and 4, the sliding body 7 has a cylindrical shape with a flange, and one side of its outer peripheral wall has a bearing hole 3.
The shaft part 11a fits into the shaft part 11a, and the other measuring part is the sliding hole 6.
The sliding flange portion 11b fits into the sliding flange portion 11b. A slit 12 traverses the outer circumferential wall in the axial direction, so that it has spring properties in the radial direction. The shaft portion 11a is provided with a protrusion 1 which is a rotation stopper and can be fitted into the groove 5.
3 is formed. Note that the protrusion 13 is the sliding collar portion 1
It does not protrude beyond the outer periphery of 1b. It is desirable that the slit 12 and the protrusion 13 be formed at symmetrical positions with respect to the axis. A tapered surface 14 is formed at the insertion side corner of the shaft portion 11a, sliding collar portion 11b, and protrusion 13 to facilitate insertion. 15 is the sliding collar part 1
This is a groove formed in the end face of 1b.

When assembling, first align the bearing holes 3 and sliding holes 6 of parts 1 and 2 on the same axis,
The sliding body 7 is inserted into the hole from the shaft portion 11a. At this time, in order to match the protrusion 13 and the groove 5,
For example, by locking a driver in the groove 15 and rotating the sliding body 7, the protrusions can be easily aligned with the grooves. When the shaft portion 11a is inserted into the bearing hole 3 and the sliding collar portion 11b is inserted into the sliding hole 6, the sliding body 7 is pressed into the slit 12 in a compressed state. Since the slit 12 and the protrusion 13 are located at symmetrical positions with respect to the axis, the state of engagement between the protrusion 13 and the groove 5 is not affected by the compressed state of the sliding body due to the compression of the slit. The rotation stop is kept stable. In this way, the sliding body 7 is non-rotatably connected to the component 1 by the protrusion 13, and is slidable between the outer circumferential surface of the sliding collar 11b and the inner circumferential surface of the sliding hole 6 with respect to the component 2. connected to. Thereafter, the screw 8 is inserted into the central axis portion 10, and the male threaded portion 9 and the female threaded hole 4 are screwed together. This screw 8 serves only as a decoration when the bearing hole 3 and the shaft portion 11a are tightly fitted together, but also functions as a retainer when the fit between the two is somewhat loose. It is something.

When parts 1 and 2 are opened and closed, sliding body 7 and part 1
Since it cannot rotate, it slides between the sliding body 7 and the component 2 to open and close it. Setting the slip torque to stably stop at a desired opening angle is determined by selecting the outer diameter of the sliding collar 11b, its wall thickness, the width of the slit 12, etc. relative to the inner diameter of the sliding hole 6. Therefore, it can be easily set.

Note that the sliding body may have a cylindrical shape without a flange, and one side may be a shaft portion and the other side may be a sliding portion.

As described above, according to the present invention, it is easy to set and manage the slip torque, it is possible to stably stop at a desired opening angle, the number of parts is small, and the slip torque can be easily set and managed.
It has a simple configuration and is easy to assemble and disassemble. Also, since the rotation stopper is provided on the opposite side of the slit,
Even in the compressed state, the position of the rotation stopper does not change, and the non-rotatable state with respect to one component is maintained stably.
