Description

[Detailed explanation of the invention] This invention is attached to a meeting frame so that its length can be adjusted freely.
The present invention also relates to a talent holder mounting device that can prevent positional displacement after mounting.

Conventionally, in a crescent lock device that is used by being attached to a matching stile such as a sliding sash, a long hole is drilled in the crescent holder from the mounting base toward the hook, and the fixing screw is inserted into the crescent holder with the long hole. A mounting device for a crescent holder is known in which the crescent holder is inserted into a hole and screwed onto a matching stile so that the crescent holder can be attached and adjusted by the length of the elongated hole.

In addition, attach a female threaded back metal to the back of the crescent bracket, insert the fixing screw into the mounting hole of the stile and the elongated hole of the crescent bracket, screw it into the female screw, and tighten the crescent bracket. There is also known a mounting device for a crescent holder which is intended to prevent displacement of the holder after it is attached.

However, with the former mounting device, after adjusting the length of the crescent bracket and attaching the crescent bracket to the meeting frame, if the fixing screw loosens, the crescent bracket may shift position. There is a drawback that the crescent lock cannot be completely engaged, causing the shoji to shake when the crescent lock is locked.

In addition, in the latter mounting device, a backing metal is attached to the crescent holder to prevent the fixing screws from loosening, so the fixing screws will not come loose immediately, but after many years of use, The fixing screw may become loose and the crescent bracket may become misaligned.

This invention was devised in order to deal with the above-mentioned drawbacks, and it is possible to install the crescent holder in a freely adjustable length, and also to create a crescent that will not shift its position even after being used for many years after installation. The object of the present invention is to provide a mounting device for a receiving metal fitting.

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

In FIG. 2, H indicates a crescent holder.

The crescent holder H is separated from a mounting base 1, a tip 2, and a hook 3.

Reference numeral 4 indicates backing metals, and at least one pair of backing metals are attached to the back side of the crescent holder H so as to face each other.

The back metal 4 is provided with a female screw 5, and the crescent holder H has a mounting base 1 corresponding to the female screw 5.
A long hole 6 facing the hook portion 3 is provided.

In addition, 7 indicates a fixing screw, which is inserted into the mounting hole provided in the matching stile 9 of the shoji 8 and the long hole of the crescent bracket H, and screwed into the female thread 5 of the back metal 4. This is the conclusion.

By the way, at least one pair of backing metals 4 are attached to the back side of the crescent receiving metal fitting H, and each of them is attached to the matching frame 9 using fixing screws 7.

According to the above configuration, the crescent holder H can be attached to adjust its length, and even if the crescent holder H is used for many years, the position of the holder is extremely unlikely to shift.

This is because, as mentioned above, in some conventional examples, a piece of back metal 4 is attached to the back surface of the crescent receiving metal fitting H.

Then, a plurality of fixing screws 7 are inserted into the mounting holes of the frame 9 and the elongated holes 6 of the crescent bracket H, and are screwed into the female screws 5 drilled in each of the back metals 4 for fastening. Ta.

However, in such a conventional mounting device, the backing metal is made of a single plate, so if one of the fixing screws 7 becomes loose, the looseness of the backing metal will affect the other fixing screw. This results in the crescent holder H itself being misaligned.

However, in this invention, the backing metal 4 is attached separately and is attached using fixing screws 7.

Therefore, even if one of the fixing screws 7 loosens and one of the backing plates 4 shakes, this does not affect the fastening of the other fixing screw 7.

Therefore, it can be said that the position of the crescent holder H itself is extremely unlikely to shift even after many years of use.

Next, a further improved mounting device for a crescent holder according to the present invention will be described with reference to FIG. 2.

First, attach at least one pair of opposing back metals 4 to the back surface of the crescent holder H, and drill a female screw 5 in the back metal 4, and attach a mounting base 1 to the crescent holder H in correspondence with the female screw 5. A long hole 6 toward the ratchet portion 3 is provided.

By the way, the plurality of back metals 4 are attached in advance to the back surfaces of both ends in the width direction of the crescent receiving metal fitting H via support pins 10, and are rotatable about the support pin portions as fulcrums.

Further, the female screw 5 of the back plate 4 is bored at its tip.

Further, the elongated hole 6 of the crescent holder H is located inside the support pin portion.

In the above configuration, the fixing screws 7 are inserted into the mounting holes of the matching frame 9 and the elongated holes 6 of the crescent holder H, and are screwed into the female threads 5 of the back metal 4 to be fastened.

Therefore, the installation of the crescent holder H is completed.

Therefore, with such a mounting device for a crescent holder, the position of the crescent holder H is extremely unlikely to shift even if it is used for many years.

Here, the misalignment of the crescent bracket H means that the mounting base 1
This refers to a situation in which the crescent holder H slides toward the hook portion 3, the fixing screw 7 loosens, and the crescent holder H swings back and forth.

However, in this mounting device, the sliding of the crescent holder H is prevented not only at the fastening portion of the fixing screw 7 but also at the support pin portion.

Further, the above-mentioned rocking is prevented by the relationship between the mounting state of the back plate 4 and the fixing screw 7.

That is, to explain in detail with reference to FIG. 4, the crescent holder H is attached in the state shown in FIG. 4a.

Attach the crescent bracket H to the matching frame 9 here.

The two fixing screws 7 both have clockwise screws.

For example, when the upper fixing screw 7 is loosened, the crescent holder H and the backing metal 4 assume a positional relationship as shown in FIG. 4.

Here, when the back plate 4 is moved, a rotational force as shown by arrow A is applied to the upper fixing screw 7, while the upper fixing screw 7
Although the lower fixing screw 7 is subjected to a rotational force as shown by arrow B when the back plate 4 is moved, the fastening force is further improved.

Therefore, the crescent holder H does not swing back and forth as described above.

In addition, in the figure, 11 indicates a locking protrusion, but the protrusion 11 that snaps is attached to the back metal 4 attached in advance to the back of the crescent holder H.
This is provided at a position where it can come into contact with the side wall of the crescent holder H to facilitate the screwing of the fixing screw 7 into the female thread 5 and to prevent excessive rotation of the back metal 4 after the crescent holder H is attached.

The crescent holder H is attached to the matching frame 9 by inserting the fixing screw 7 into the mounting hole and elongated hole 6 of the matching frame, and screwing it into the female thread 5 of the back metal 4 to tighten it. However, it is troublesome to screw the fixing screw 7 into the female thread 5, especially in the field.

Therefore, the protrusion 11 is provided so that the back metal 4 is locked when the female screw 5 is in a position corresponding to the elongated hole 6.

Therefore, the fixing screw 7 can be easily screwed into the female thread 5.

Furthermore, the locking protrusion 11 also serves to prevent excessive rotation of the back metal 4 after the crescent holder H is attached.

Thus, this invention has the above structure, but according to the mounting device for the crescent holder according to this invention, ■ At least a pair of backing metals are attached to the crescent holder, and the holder is assembled with each fixing screw. Since it is attached to the frame, even if one of the fixing screws loosens, the other fixing screw will be tightened, so there is no risk of the crescent holder being misaligned.

■ Furthermore, attach a pair of backing metals to the crescent holder in advance using support pins, insert fixing screws into the mounting holes of the stile and the long holes of the crescent holder, and screw them into the female screws provided at the tips of the backing metals. If they are joined together, it is possible to completely prevent the crescent holder from shifting even after many years of use after it is installed.

That is, even if one fixing screw becomes loose, the other fixing screw will be further tightened by the rotational force of the back metal.

■ In addition, if a locking protrusion is provided on the back of the crescent holder so that it comes into contact with the side wall of the backing metal that has been installed in advance, there are advantages such as making it extremely easy to screw the fixing screw into the female thread of the backing metal. have

Therefore, the practical value of this idea is extremely great.
