Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention mainly relates to a fixture used for attaching objects to concrete walls and floors.

(Prior art) Conventionally, for the purpose of attaching an object to a concrete wall or floor, a cylindrical container is provided with a flange with a circular opening on the top surface. A short cylindrical rotating body formed with a long groove is rotatably fitted into the long groove, and a screw (nut) whose rotation is prohibited by both side walls is slidably fitted into the long groove. For example, it is known as Utility Model Application Publication No. 50-26275.

(Problem to be solved by the invention) However, in the above-mentioned conventional fitting, the rotating body into which the screw body is slidably and loosely fitted is loosely fitted into the cylindrical case, so that the screw When tightening your body,
There was a problem in that the rotating body rotated around inside the container, making it impossible to perform the tightening work quickly and smoothly.

The present invention solves the above-mentioned problems, and prevents the rotary body into which the screw body is loosely fitted from rotating inside the container when tightening the screw body, so that the tightening work of the screw body can be performed quickly and smoothly. The purpose is to provide a fixture that can be used.

(Means for Solving the Problems) In order to solve the above problems, the present invention rotates a rotating body that forms a long groove with a flange in a container with an open top surface and a flange. In the mounting device, in which a screw body is slidably and loosely fitted into the long groove and is prohibited from rotating, a part of the side wall of the container is made to protrude inwardly to prevent the container from turning. On the side wall of the box,
A rotation regulating projection for regulating the rotation of the rotating body is provided, and a packing is interposed between the rotating body and the inner bottom surface of the container.

(Function) In use, as shown in Figure 5, the container 1 is buried in the concrete floor 6 and the object 7 is screwed therein with bolts 8. In this case, the mounting holes 7a of the object 7 and Even if there is an error in the mutual position of the containers 1 (fixtures), the rotating body 2 can be rotated,
By sliding the screw body 3 within the long groove 2b, the position of the screw body 3 can be changed over a wide range to match the attachment hole 7a, and the attachment work can be performed easily and quickly. Note that when tightening the screw body 3, the rotation of the rotary body 2 is prevented by a rotation regulating protrusion 4 provided by protruding a part of the side wall 1c of the container 1 inward, and the rotation of the rotary body 2 is prevented. Since loads (frictional resistance and cushioning force) are applied over a wide range to the bottom surface of the screw body 3, the tightening operation of the screw body 3 can be performed quickly and smoothly. Furthermore, since the opening of the container 1 and the long groove 2b of the rotating body 2 are provided with flanges 1a and 2a, respectively, the rotating body 2 and the screw body 3 escape from the opening of the container 1 and the long groove 2b of the rotating body 2. There is nothing you can do.

(Example) Figures 1 to 5 show an example of the present invention,
Reference numeral 1 denotes a cylindrical container having a circular upper surface and a flange 1a. 1b is the bottom cover of the container 1. Reference numeral 2 denotes a short cylindrical rotating body in which a long groove 2b with a flange 2a is formed, and is loosely fitted into the container 1 so as to be horizontally rotatable, and the rotating body is provided in the long groove 2b. A screw body (nut) 3 whose rotation is prohibited by both side walls 2c and 2d of the movable body 2 is slidably fitted with play. Reference numeral 4 denotes a rotation regulating protuberance formed by protruding a part of the side wall 1c of the container 1 inward, which prevents the rotation of the rotating body 2 that is rotatably fitted into the container 1. It regulates the Reference numeral 5 denotes a packing interposed between the rotary body 2 and the bottom cover 1b, which is made of, for example, a plastic foam sheet or other appropriate material, and is designed to apply appropriate loads (frictional resistance and cushioning) to the movement of the rotary body 2. force). 6 is a concrete floor, 7 is an object, 7
A is a mounting hole of the object 7, and 8 is a bolt.

In this embodiment, the screw body 3 is a nut, but the same applies if it is a bolt, and the mounting tool is not limited to being buried in a concrete floor, wall surface, etc. It can be used in all cases where two objects are screwed together, and is attached to one object by screws or other means without embedding if necessary, and to which another object is screwed. You may also wear them.

(Effects) As explained above, according to the present invention, a rotating body having a long groove with a flange is rotatably fitted into the container having an open upper surface and a flange, and In a mounting device in which a screw body, which is prohibited from rotating, is slidably and loosely fitted into a long groove, a part of the side wall of the container is made to protrude inwardly, and the side wall of the container is
Since a rotation regulating projection for regulating the rotation of the rotating body is provided and a packing is interposed between the rotating body and the inner bottom surface of the container, when tightening the screw body, the rotation of the container is Rotation of the rotating body can be restricted by a rotation regulating projection provided on a part of the side wall of the rotating body, and a load (frictional resistance force and cushioning force) can be applied over a wide range to the bottom surface of the rotating body. As a result, the screw body can be tightened quickly and smoothly by the resistance force of the rotation regulating protrusion and the load effect of the packing, and the two objects can be attached easily and quickly. .
