Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pivoting device suitable for pivoting audio racks and other doors, especially doors made of glass.

As shown in the drawing, a set screw for fixing the door is attached to a pair of opposing walls of the main body formed in a groove shape, and the wall between the opposing walls is used as a pivot support for a door made of glass or the like. Some have support shafts erected on the outside. This involves inserting the end of the door into the main body, fixing it with a set screw, inserting the support shaft into a shaft hole of a box, etc., and attaching the door to the box. Conventionally, such a pivot support body has been formed by bending a metal plate. Therefore, although it is possible to securely fix the door, there are manufacturing problems that require time and effort, such as bending the metal, erecting a support shaft relative to it, and providing screw holes. When the door is made of glass, it is necessary to interpose a plate made of plastic or the like between the opposite wall of the main body and the door. In order to solve these problems, it has been proposed to make the entire body out of synthetic resin, but since synthetic resins generally cause creep,
For example, if the product gets hot while being transported by car with the door attached, the opposite wall of the main unit will creep, which will reduce the force used to secure the door with the set screw, causing the problem of the door separating. Occur. This also occurs with long-term use.

In this invention, the main body of the shaft support is made of synthetic resin,
The purpose is also to maintain the fixing force of the door even when a coolip occurs in the main body, and to eliminate separation of the door.

The present invention has a set screw on one opposing wall of the main body having a concave cross section, and at least the inner surface of the opposing wall having the set screw is an inclined surface with the tip side of the opposing wall tilted inward. The main body is entirely made of synthetic resin.

This shaft support inserts the end of the door into the main body and pressurizes the door with a set screw.
When the door is pressurized with the set screw, the main body is fixed to the door by sufficiently tightening the opposing wall having the set screw to slightly elastically deform outward.

An embodiment of the pivot support of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a main body formed with a concave cross section, the entire opposite wall 2A having approximately the same thickness is inclined inwardly, and the opposite wall 2A is inclined inwardly. The distance between the openings of 2A and 2B is narrower than on the back side. Reference numeral 3 denotes a screw hole provided through the opposing wall 2A, into which a set screw 4 made of synthetic resin is screwed. Reference numeral 5 denotes a support shaft erected on the outer surface of the connecting wall 6 between the main body 1 and the opposing wall 2. and,
The main body 1 and the support shaft 5 are integrally molded of synthetic resin, and the synthetic resin is polyamide resin mixed with about 50% short glass fibers.
Synthetic resins with high hardness and excellent creep properties, for example, Mitsubishi Kosikagaku Co., Ltd.'s trade name "Renny 1032" are used.

To attach the door using this pivot support, as shown in FIG. 1 to the door 7. In this case, it is sufficiently tightened to the extent that the inwardly inclined opposing wall 2A opens outward due to elastic deformation. Then, move the door 7 to the box body 8.
Attach to the shaft.

As described above, the pivot support body 1 is attached to the door by pressing the set screw 4 supported by the opposing wall 2A against the door inserted into the body 1. The opposing wall 2A, which is inclined by the reaction force against the door, is elastically deformed and opens outward. Therefore, even if the main body 1 is left in a relatively high-temperature enclosure in this state or creep occurs on the opposing wall 2A after a long period of time,
The amount of deformation is within a range smaller than the amount by which the opposing wall 2A is elastically deformed in advance, so the opposing wall 2A maintains an elastically deformed state and pressurizes the door 7 via the set screw 4 with its elasticity. This can solve the problem of the door falling off due to the creep of the opposing wall 2A.

Incidentally, the door was inserted into the synthetic resin main body 1, and the set screw 4 was tightened to such an extent that the inclined opposing wall 2A became almost parallel to the surface of the door due to elastic deformation, and heated to 70°C. Although the door was left in the atmosphere for 4 hours, there was almost no change in the condition of the opposing wall 2A, and the door was able to remain firmly fixed.

FIG. 4 shows a second embodiment, in which the inner surface of the opposing wall 2A is
The tip side is tilted inward to form an inclined surface. That is, the opposing wall 2A becomes thicker toward its tip end.

Note that both of the opposing walls 2A and 2B are inclined inward as shown in FIG.
It is also possible to make both inner surfaces sloped as shown in FIG. In the second embodiment as well, the door can be maintained in a firmly fixed state as in the example shown in FIG.

As in the example in Fig. 1, if the entire opposing wall 2A is made to have approximately the same thickness and is slanted inward, when the opposing wall 2A is attached to the door and the opposing wall 2A is opened slightly outward, the opposing wall 2A The entire wall 2A is approximately parallel to the surface of the door, and its appearance can be improved. Set screw 4
Since it is made of synthetic resin, when its tip is pressed against the door, it deforms slightly along the surface of the door, making it possible to pressurize the door more reliably. However, the set screw 4 can also be made of metal. As a material for forming the main body 1, the above-mentioned resins are suitable as synthetic resins in terms of heat resistance, but polyacetal and the like can also be used.

As described above, the fixture of the present invention has a main body 1 made of synthetic resin and an opposing wall 2 having at least a set screw 4.
The inner surface of the main body 1 is sloped so that the width of the opening is narrower than the back side, and the door is inserted into the main body 1, and the facing wall 2 is pushed outward by the force of pressurizing and fixing the door with the setscrew 4. It is elastically deformed, and the door is also fixed by that elasticity.
Therefore, even if creep occurs in the opposing wall 2, by making the amount of deformation smaller than the amount of elastic deformation of the opposing wall 2, even if creep occurs in the opposing wall 2, the amount of deformation will be smaller than the amount of elastic deformation of the opposing wall 2. The door can be strongly fixed, and the door can be prevented from falling off due to creep of the opposing wall 2. When the opposing wall, which is substantially perpendicular to the connecting wall 6, is elastically deformed outward as in a known fixture, the angle between the connecting wall 6 and the opposing wall becomes larger than 90 degrees. , stress concentration is likely to occur at the base of the opposing wall, and creep is likely to occur. However, in the present invention, the opposing wall 2 whose inner surface is sloped is elastically deformed outward. Therefore, when the opposing wall 2 is elastically deformed, the angle with respect to the connecting wall 6 is close to a right angle, stress concentration is less likely to occur on the opposing wall 2, creep is less likely to occur, and the structure can be maintained for a long period of time. It is possible to maintain a firm fixation to the door even at high temperatures.
