JPS58738Y2 - Clamp for long press - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a long-press clamp used to temporarily tighten the long-press to the lintel when the long-press is attached and fixed to the lintel.

Conventionally, there has been a clamp of this type as shown in Fig. 1, in which an inverted rJJ-shaped receiver has a substantially right triangular bracket 2' fitted onto a member 1' so as to be able to move up and down and rotate freely. The bracket 2' is secured by a wing nut 3' screwed onto the lower end of the member 1', and the bracket 2' is stopped by a bolt 4', which saves time and effort in long-press tightening. Moreover, since the line of action of the upper tightening blade of the wing nut 3' does not face the surface 1a of the receiver of the member 1', the upper tightening blade cannot be fully utilized, resulting in wasted force. There was a drawback that I had to add.

The object of the present invention is to provide a device that can eliminate the above-mentioned drawbacks.

Hereinafter, an example of the implementation of the present invention will be explained in accordance with the drawings. As shown in Fig.
It is folded back at an angle of 80 degrees to form an inverted J-shape, and the receiver surface 1a is placed or bent at a right angle at the folded end.

The lower end of the long side of the member 1 is shaped like a round bar, and the bracket 2
Elongated holes 2a formed on three sides of the bracket 2 are rotatably fitted into the bracket 2, and the bracket 2 is prevented from falling off by a nut 5 screwed under the bracket 2.

A fastener 3 made of a threaded rod is screwed onto the free end of the bracket 2 in parallel to the longitudinal direction of the receiving member 1, and a backing plate 3b such as a rubber disc is attached to one side of the upper end of the fastener 3. Glued tightening plate 3
A is rotatably attached, and a grip 3c is fixed to the bottom end.

The fastener 3 is provided at a predetermined position on the free end of the bracket 2 so that the receiver of the member 1 can be positioned directly f of the surface 1a.

The bracket 2 has a click stop mechanism 4 for stopping the fastener 3 and the receiver from easily rotating relative to the member 1 when the receiver is located directly below the surface 1a.

Here, in the mechanism 4, a hole 4a shallower than a hemisphere is recessed in the circumferential surface of the member 1, and the fastener 3 is inserted into the surface 1a of the member 1.
When located directly below the hole 4a? The ball 4b into which the iB is inserted is accommodated in a small hole 4c formed in the peripheral wall of the long hole 2a of the bracket 2, and the ball 4b is subjected to the pressure of a plate spring 4d having a C-shaped cross section and an annular shape wound around the bracket 2. It has a vertical structure.

To explain how to use and operate the clamp of the present invention according to the above structure 6, first, as shown by the imaginary line in FIG. The receiver is located on the opposite side to the surface 1a, and the receiver 1a of the member 1 is moved over the rising part of the long press 6 and brought into contact with the horizontal part.

This operation is easy because bracket 2 is facing backwards.

Next, flip the bracket 2 180 degrees so that it faces forward.
As shown in FIG.
Holding it in place, place the uke directly below 1a.

At this time, the ball 4b of the clix [ruff mechanism 4] is pushed into the hole 4a of the receiver member 1 by the leaf spring 4d, so the bracket 2 can be easily and precisely stopped at the position. .

Subsequently, the tightening tool 3 is turned through the grip 3c, the tightening plate 3a is pressed against the lower surface of the lintel 1 through the contact plate 3b, and the lintel 7 and the long press 6 are strongly tightened.

At this time, since the line of action of the fastener 3 coincides with the face 1a of the receiver, all of its acting force is effectively applied to the lintel 7 and the long press.

Incidentally, since the tightening plate 3a is rotatably attached to the fastener 3 and is independent of the rotation of the fastener 3, it does not interfere with tightening.

As explained below, the present invention provides various effects such as being able to quickly, reliably, and firmly fasten the long press to the lintel with an extremely simple operation.
