Description

[Detailed description of the invention] [Industrial application field] This invention is suitable for crescent locks used on sliding windows and sliding door frames, especially in hard-to-reach places such as kitchen bay windows. This invention relates to a crescent handle used in a crescent lock suitable for locking doors.

[Conventional technology]

As is well known, a crescent lock is made up of a combination of a crescent and a crescent receiver, and by rotating the handle of the male crescent in the direction in which the shoji is facing, the crescent lock locks into the crescent lock. It has an excellent function of locking and pulling the shoji at the same time, and is one of the most convenient door locks, and is widely used for various types of sliding windows and sliding doors.

[Problem that the invention attempts to solve]

However, since the crescent lock is attached to the middle part in the height direction of the connecting frame of the shoji, for example, in the case of the crescent lock K installed on the bay window W of the kitchen as shown in Fig. 5, the crescent lock is attached to the bay window. A sink S is often installed on the floor F in front of W, so when closing the bay window W, it is difficult to reach the handle H of the crescent C, unless you are very tall. There was a problem in that it was difficult to easily open and close the crescent lock K of the bay window W. Therefore,
Some people skilled in the art have attempted to remotely control the Crescent by attaching chains, links, or other power transmission media to the Crescent, or by attaching a servo motor to the Crescent, but these efforts have only made the structure extremely complex. However, to rotate the crescent, significantly different torques are required at the beginning and end of the rotation due to the relationship with the crescent receiver, so it is surprisingly difficult to mechanize and is far from practical. is the current situation.

The purpose of this invention was to use unique creativity in the shape of the handle of the crescent itself, without using a remote control device or electric device, which has a complicated structure and has difficulty in operation, as described above. To provide a new crescent handle that allows anyone to easily lock and unlock a crescent lock attached to it.

[Means for solving problems]

This device was devised to achieve the above-mentioned purpose, and consists of extending the crescent handle several times its normal length, and extending this extension vertically upward in the locking position. It is characterized by being branched into a main rod that protrudes toward the interior, and a sub-rod that projects diagonally upward toward the indoor side.

〔Example〕

Hereinafter, the structure and operation of the crescent handle according to the present invention will be explained in detail with reference to the drawings of the embodiment. There are two types: one that is attached, and one that has an extension part formed integrally with the crescent, so we will first explain the handle _H1 , which is an attachment type that allows you to use the existing crescent as is.

The handle H ₁ in Fig. 1 shows an example of its concrete implementation structure. , 4 are attached to the outer surface of the connecting frame M of the shoji, and in this respect, the structure is exactly the same as that of the conventional crescent, but in the case of this embodiment, the handle connected to the main body 1 of the crescent C An attachment 5 of the handle _H1 is removably connected to the portion 1a by a shaped retaining metal fitting 6 and a set screw 7.
FIG. 3 shows the relationship between the shape of this attachment 5 and the crescent body 1. At the base of the attachment 5, there is a handle 1a of the crescent body 1.
A groove 8 of the same shape that fits into the groove 8 is provided.
Insert the handle 1a of the crescent main body 1 from the side as shown by the arrow, engage the side wall 6b of the retaining metal fitting 6 with the notch 1b provided on one side of the handle 1a, and insert the metal fitting 6 from above. After fitting, the attachment 5 is connected and fixed so that it does not come off from the handle portion 1a of the crescent body 1 by tightening the retaining metal fitting 6 with a set screw 7. The handle _H1 of the attachment 5 has a normal length L,
That is, the handle part 1 provided in the conventional crescent
The extension part 9 is extended to several times the length of a, and the main rod 11 projects vertically upward from the base 10 in the locking position as shown in FIG. The tips 11a and 12a of both the main and sub-rods 11 and 12 are bent inward in consideration of the operability of the handle _H2 , and are suspended downward from the tips of the sub-rods 12. A chain 13 is provided, and a weight 14 is attached to the lower end of the chain 13.

In addition, the handle H ₂ in FIG. 4 shows another similar embodiment of the present invention, and in this case, the lengths of the main rod 11 and the sub-rod 12 of the handle H ₂ and their protruding directions are as described above. Although it is basically the same as the attachment type handle H ₁ , the main and sub-rods 11 and 12 of the handle H ₂ are molded integrally with the crescent body 1 .

Since the handle of the crescent according to the present invention has the above structure, if the handle _H1 is an attachment type, it can be attached to the handle part 1a of the crescent body 1.
Attach the handle _H2 to the handle part 1 as shown in Figure 1.
If the handle is molded integrally with a, use it as is, and when the handle _H1 or _H2 is in the locking position, to unlock the crescent C, it must be connected to the sub-rod 12 on the front side. If you directly pull the chain 13 or sub-rod 12 downward, the crescent body 1 will rotate downward about the pin 2 as shown in Figure 2, and the crescent body 1 will be locked from the crescent receiver (not shown). Since the claws 1c are removed, the shoji can be opened and closed freely. In addition, in order to lock the crescent C after closing the shoji, first rotate the tip 11a of the main rod 11 upward until it reaches a position where you can reach it.
After that, locking is performed by a two-step operation in which the tip end 12a of the sub-rod 12 is further rotated upward.
When the tip 12a of the sub-rod 12 is within reach, the locking can be completed at once by rotating the tip 12a of the sub-rod 12 upward from the beginning.

[Effect of idea]

As described above, if this invention is applied to a crescent lock, the handle of the crescent can be extended several times its normal length, and this extension can be used as a main rod that projects vertically upward in the locked position. It is branched into a sub-rod that protrudes diagonally upward toward the indoor side, so
For example, even if a crescent lock is installed in a hard-to-reach place such as a kitchen bay window, anyone can easily turn and lock it by operating either of the main and sub-rods that protrude diagonally toward the interior of the room. It is very convenient because it can be unlocked, and the handle immediately after unlocking can be used as a pull for the inner shoji to open and close the shoji.Also, the handle of this invention does not have a complicated structure like the conventional one. Crescent's operability has been improved by simply improving the handle itself, without using a remote control device or electric device, which has difficulties in operation.
It has excellent advantages such as simple structure, low production cost, and high practicality.
