Description

[Detailed description of the invention] A. Field of industrial application: The present invention relates to an improvement of a door fastening fitting used in construction, which consists of a mounting seat, a catch, and a moving rod.

B. Conventional technology: As shown in Figure 6, conventional door locking fittings use a moving rod rotatably pivoted on a mounting seat to temporarily tighten the door by hooking it onto a hook on the catch, and then tightening the moving rod from the outside. The set screw was turned so that the tip of the screw engaged with the groove so that the screw could not be raised.

Therefore, when the door is opened, the moving rod hangs freely, and when the door is opened and closed, the moving rod moves around unsteadily, giving an unsightly appearance and sometimes preventing damage to the door or pillars. There was also the drawback that if the set screw was not fully tightened, the door could be locked by raising the movement lever from the outside.

C. Purpose of the invention: The purpose of the invention is to provide a door clamp that is not much different in usage from conventional door clamps, is easy to use, has a reliable crime prevention effect, and can be used for a variety of purposes.

D. Structure of the invention: The structure of the invention will be explained with reference to the drawings. 1 is a mounting seat, 2 is a catch seat, and 3 is a moving rod.

A support shaft 4 is protruded from the center of the mounting seat 1, and a barrier 5 is curved and protruded integrally with the mounting seat 1 from one longitudinal side. Also, the center of barrier 5 is the moving rod 3
A notch 6 is formed by cutting out a width slightly larger than the width of the notch.

A hanging piece 7 is provided on the catch seat 2 in a curved manner.

A knob 8 is fixed to one end of the moving rod 3, and a long hole 9 in the length direction of the moving rod 3 is provided at the other end.

The elongated hole 9 is fitted onto the support shaft 4 and lightly caulked 1.
It is set to 0. Therefore, although the movable rod 3 is slidable and rotatable relative to the support shaft 4, the movable rod 3 cannot be separated from the support shaft 4. The washer 11 is fitted in order to make the movement of the moving rod 3 smooth.

In addition, regarding the relationship between the size of the mounting seat 1 and the size of the moving rod 3, the distance D from the center of the support shaft 4 to the barrier 5 and the size of half the width of the moving rod 3 are defined as D>. There is. Therefore, when the movable rod 3 is rotated upward by 90 degrees, a gap of D- is necessarily created between the movable rod 3 and the barrier 5.

In addition, 12 is a door, 13 is a column 14 is a door 12 and a column 1
3, 15 is a groove, and 16 is a set screw.

E. Effects: Since the present invention is constructed as described above and shown in the drawings, it has the following effects.

As shown in Figure 1, hold the moving rod 3 horizontally and hang it on the hook 7 of the catch seat 2, push the moving rod 3 to the right, and move the right end of the moving rod 3 to the right from the notch 6 of the barrier 5 of the mounting seat 1. If it protrudes, even if you insert a thin iron plate, the tip of a screwdriver, etc. into the gap 14 between the door 12 and the pillar 13, lift the moving rod 3 upwards, and try to remove the moving rod 3 from the hanging piece 7, the moving rod 3 will not move. The edge hits the barrier 5 and the moving rod 3 cannot be rotated.

In addition, when the door fastener of this invention is not used, the moving rod 3 can be rotated 90 degrees upwards (the position indicated by the one-dot chain line) and then lowered (the position indicated by the two-dot chain line). There is only a small gap between the moving rod 3 and the barrier 5, so even if the door 12 is violently opened and closed, the moving rod 3
It doesn't swing around.

Effect of the invention: If the moving rod 3 is fitted into the notch 6 of the barrier 5, the moving rod 3 cannot be illegally rotated from the outside, so the crime prevention effect is extremely high.

Further, when the door 12 is left open, if the moving rod 3 is turned up 90 degrees and lowered, the moving rod 3 will not swing around and the metal fittings will fit better.
In addition, it does not prevent damage when opening and closing the door, and it does not damage the door or pillars.

Furthermore, as shown in Fig. 5, if a male thread is cut into the support shaft 4 of the mounting seat 1 and a nut 17 is screwed into this, the crime prevention effect and the effect of stopping the swinging of the moving rod 3 will be more secure. Become.

In addition, the proposed door fastener, excluding the catch 2, can be attached to the lower frame of a window or shutter and used as an ``Otoshizaru'' (Otoshizaru).
