DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fixture for attaching one article to another.

After the commonly used bolts or screws are attached to the item i, they may be loosened or removed with an ordinary spanner or screwdriver or the like by accident.

The fixing device of the present invention was developed to be rounded so that the fastened and fixed state is maintained and will not be loosened unless a special tool is used, and it has the following configuration conditions A to H. It is characterized by That is, (4) it is equipped with a body that presses one article against another; (a rotating member integrally provided with a wire rod extending downward at the bottom of the crane body is rotatably attached to the crane body; (C) Providing a retaining part to which a tool is removably attached to the exposed portion of the rotating member; (G) Providing a pin insertion hole that communicates between the main body and the rotating member. (2) In the pin insertion hole, a driver pin and an operating pin which are biased outwardly by a spring are loosely mounted; straddling the interface of the rotary member and non-rotatably locking the main body and the rotary member; in the working state, the working pin projects a portion into a narrow tool insertion provided in the rotary member; and (
g) When the tool is engaged with the retaining portion of the rotating member, the protruding portion of the working pin is pushed inward against the spring through the driver pin, and the interface between the driver pin and the working pin is It has eight structural conditions: it must match the interface between the main body and the rotating member.

The present invention will be explained below based on embodiments shown in the drawings.

Each member of the fixture of the present invention is usually made of a metal material such as brass or iron, but if strength permits, other materials such as a hard synthetic resin material may be used for part or all of it.

In FIGS. 1 to 4, 1 is the main body of the fixture of the present invention for pressing one article A onto another article B, and its outer shape can be arbitrarily designed. Although the side surface is provided with an inclined retaining part 1a for holding down the article B, if the article B is thin, for example, it can be held down with the bottom surface of the main body l, so the holding part 11 can be used in other shapes. 01b, which can be of the form 1 to a predetermined position accurately, but it is not necessary to provide it.

Reference numeral 2 denotes a cylindrical rotating member which is rotatably attached to the main body 1, and a wire rod 3 extending downward is integrally provided at the center of the bottom portion 2a. This wire rod 3 may be fixed to the rotating member 2 as a separate member, or may be manufactured integrally. The lower half of the rotating member 2 is loosely fitted into a fitting part 1c provided on the main body 1, and the wire rod 3, which is rotated together with the rotating member 2, is continuous with the fitting part 1c of the main body 1. It is loosely fitted into the through hole ld provided so as to protrude downward. The rotating member 2 and wire rod 3 incorporated into the main body 1 in this way are
It is prevented from being pulled out of the body 1 by a retaining ring 4 provided on the protruding part of the wire rod 3 or by other means. Note that the reference numeral 1e is a stepped portion provided at the bottom of the main body 1 for attaching a ring.

The exposed portion of the rotating member 2 is provided with a
For example, a retaining portion 2b having a rectangular cross section is provided, to which a rear-end tool 5 for rotating is removably engaged. A thin tool 5 is used to rotate the retaining portion 2b of the rotating member 2.
A narrow insertion part 2C for a tool is provided, into which a tool is removably fitted.

This insertion portion 2C needs to be made narrower by + so that fingers cannot be inserted into it.

Reference numeral 6 designates a pin insertion hole provided at at least one location (in the illustrated example, two locations) between the main body 1 and the rotating member 2, extending between the two. , from the inside (lower side in FIGS. 2 and 4), the compression spring 7: the driver pin 8 and the working pin 9 are loosely installed. In the normal state where the tool 5 is not engaged (see FIG. 1 or FIG. 4), the driver pin 8
is biased by a compression spring 7 and positioned across the interface P between the main body 1 and the rotating member 2, and prevents the rotating member 2 from rotating relative to the main body 1. On the other hand, the working pin 9 normally projects a part of it, that is, the small diameter part 9&, into the narrow tool insertion part 2C through the small hole 6a provided in the rotating member 2 and communicating with the pin insertion hole 6. That's how it is.

The shape of the tool 5 used in combination with the fixture of the present invention can be arbitrarily designed depending on the design of the rotating member 2, but in the illustrated example, it is formed into a thin plate shape. A U-shaped retaining receiving portion 5a corresponding to the rectangular cross-section retaining portion 2b of the rotating member 2 is provided at the tip of the bowl and the tool 5.
A guide groove 5b is provided to guide the working pin 9 so as not to collide with the protruding portion 9a of the working pin 9 when it is inserted into the narrow insertion portion 2c of the rotating member 2. Therefore, when this tool 5 is engaged with the retaining part 2b through the insertion part 2c of the rotating member 2, the protruding part 9a of the working pin 9 slides along the guide groove 5b at the beginning of the insertion of the tool 5, As shown in FIG. 2, in the final stage of insertion, the tool 5 is pushed by the bottom surface and pushed into the small hole 6a and pin insertion hole 6 through the driver pin 8 against the biasing force of the spring 7. It turns out. Here, since the interface Q between the driver pin 8 and the working pin 9 coincides with the interface P between the main body 1 and the rotating member 2, the driver pin 8 locks the main body 1 in a non-rotatable manner. The rotation member 2, which had been held in place, is released from its restraint, and can now be rotated by hand by rotating the tool 5 and by rotating the screw punch 3.

As clearly shown in FIG. 3, the reference numeral 2d is an inclined surface provided on the bottom 4=28 of the rotating member 2 in a continuous manner with the pin insertion hole 6 along the circumferential direction. When in use, rotate the rotating member 2 in the tightening direction (clockwise in Figure 1, counterclockwise in Figure 3).
When the rotating member 2 and the main body 1 are rotated, the engagement between the rotating member 2 and the main body 1 by the driver pin 8 is released. That is, due to the presence of this inclined surface 2d, the rotating member 2 can be rotated by hand in the tightening direction without using the tool 5, and the driver pin 8 can be rotated in the loosening direction of the rotating member 2. It is intended to restrict only the However, whether or not to provide this inclined surface 2d is optional.

Next, with reference to FIGS. 1, 2, and 4, examples of use of the fixture of the present invention will be described.

The fixing device of the present invention can be used to secure a hollow article A as shown in FIG. When attaching another article B to the article A, first, a through hole At is provided at the main fixing device mounting position of the article A, and a corresponding screw member C is screwed into the inside of the article A to screw the screw punch 3. to be fixed. C1 is a female thread provided on the corresponding threaded member C.

The corresponding screw member C does not necessarily need to be fixed. If a female thread is directly cut and provided in the through hole A3 of the article A, it is of course unnecessary to provide the corresponding threaded member C, and a normal nut can also be used as the corresponding threaded member C. Although the screw punch 3 in the illustrated example has a male thread, it is also possible to make the lower part of the screw hole hollow and provide a female screw on the inner wall thereof. Needless to say, the corresponding threaded member in this case is bolt-like.

If necessary, an auxiliary piece or the like is fixed to the above-mentioned article A at a position opposite to the installation position of the main fixing tool, for example, with a pole.

Here, while applying the opposite part B of the other article B to the auxiliary piece, the bottom surface of the other article B is brought into contact with the top surface of one article A. Next, the fixing tool is inserted into the rotating member 2. The tool 5 is fitted into the portion 2c, and the retaining receiving portion 5a at the tip thereof is engaged with the retaining portion 2b of the rotating member 2. Then, a predetermined position B1 of article B
While still holding the fixture body 1, the rotating member 2 and the screw punch 3 are rotated by the tool 5, and the screw punch 3 is screwed into the corresponding screw member C described above, thereby fastening the article B. In addition, if the rotating member 2 has an inclined surface 2d continuous to the pin insertion hole 6 on the bottom 2a, the rotating member 2 and screw punch 3 are manually rotated in the tightening direction with respect to the main body 1. In such cases, the tool 5 can also be used only in the final stages of tightening.

After one article A is fastened to the other article B as described above, the tool 5 is removed from the rotating member 2 of the fixture and stored.

In the fastened state by the fixing device of the present invention, as shown in FIG. Since the screw 3 is restrained by the pin 8, the screw 3 cannot be rotated in the loosening direction unless the tool 5 is used. Since the fixation of the eye is reliably maintained without the use of any special tools, it is possible to loosen the fixing device by fraud or mischief, and to remove the other article B attached to one article A. This is extremely effective in preventing theft.
