DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crescent lock for windows.

[0002]

2. Description of the Related Art A crescent lock is generally used to maintain security and airtightness of a window. Conventionally, a pedestal, an engaging body and a handle are used as main members and integrated, and a sash is used as an inner sash. Most are attached to the side of the frame. In addition, a receiver is attached to the frame of the outer sliding door. By turning the handle of the main body, the engaging body and the receiver are engaged to prevent both sliding doors from opening, and the drawer and pulling functions are airtight. Can be improved.

[0003] Japanese Utility Model Laid-Open Publication No. Hei 6-32641 reports that only an engaging body of a crescent lock is built in a combination frame of a shoji. This is to improve the security surface by making it difficult to visually see the engagement between the engaging body and the receiving part from outside, and the mechanism part is inside the base and integrated with the handle. It is almost the same as Crescent Tablets.

[0004]

A conventional crescent lock has a mechanism for reducing the overall size of the sash because there are mechanical members such as an engaging body, a rotating shaft, and a spring inside the pedestal. As the frame becomes thinner, it is inevitably protruding from the side of the sash, which limits the design and design.

In addition, since the pedestal including the mechanism and the handle are integrated, various types of crescent locks are required in accordance with various sash windows, and the same type of sash window requires different handle lengths and different colors. There are types, and there is a tendency to increase the types of products, there is no progress in common use of parts, and there is a problem in management of inventory and the like.

The pedestal is often a relatively large part because it has a built-in mechanical component and requires strength. Of course, the relatively expensive die-casting product which is currently most frequently used is of course used. However, in the case of other manufacturing methods, it is necessary to apply a surface treatment having a good design appearance, and it can be said that the proportion of the pedestal in the total cost of the crescent tablet is the largest.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a crescent tablet which is more excellent in design, can achieve commonality of parts, reduce types and management, and can reduce the cost. The purpose is to provide.

[0008]

According to the present invention, the following technical means have been adopted in order to achieve the above object. A base seat is provided that can be inserted into the hollow part of the sash's inner frame. A rotating shaft having a connecting portion for connecting to a handle attached from the outside and an engaging body are rotatably assembled to the base seat. Parts such as a spring and a resin ring are also incorporated into the base seat at the same time, and all functions as a crescent lock other than the handle are concentrated in this mechanism main body.

[0009] In the mating frame of the inner sash of the sash, a portion where the engaging body protrudes and retracts and a portion where the base seat and the handle are attached are cut out, and the mechanism main body portion is inserted and fixed in the frame. Similarly, the handle is provided with a connecting portion to the rotating shaft, and the handle is inserted from the side of the frame of the shoji and fixed to the rotating shaft. The sash's outer door frame is also cut out and a receiver is attached.

With such a configuration, it is possible to provide a crescent lock with a detachable handle in which the entire mechanism body is built in the frame. Also, by making the mounting hole cut out in the mold material into an elongated hole, it is possible to draw, draw, and adjust the position in the vertical direction at the mechanism main body and the receiver.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. Figure 1 shows the sash frame with the crescent lock attached. FIG. 2 is an exploded perspective view of the crescent tablet. The outline of the mounting method will be described with reference to FIG. As shown in FIG. 6, a cutout is formed in advance in the joint frame 35 of the inner sash, and the mechanism main body part a is inserted into the hollow portion of the mold from above and below the joint frame 35 of the inner sash and then fixed. By attaching the handle portion b to the rotating shaft 3 of the mechanism main body portion a, the handle 7, the rotating shaft 3 and the engaging body 2 are integrated, and the lock can be unlocked by rotating the handle 7.

Next, each part will be described in detail. Figure 3
FIG. 3 is an exploded perspective view of a mechanism main body part a. The engaging member 2 and the rotating shaft 3 are previously fixed to the engaging member caulking pin 16 and the caulking hole 17.
And integrated by fixing means such as caulking. Next, the integrated engaging body 2 and the rotating shaft 3 are fitted into the base seat 1 and held rotatably and not to come off.

Further, similarly to the conventional crescent, the engaging body 2
However, it is better to urge the wire spring 6 so that it comes to a completely returning position or a completely locked position. By sandwiching the resin ring 4 between the rotating part of the rotating shaft 3 and the base seat 1, the rotation can be made smooth and the wear of the rotating part can be prevented. Further, a projection such as a cut-and-raised portion is provided on the base seat 1 so that the engagement body 2 rotates 180 degrees only in a necessary direction, thereby restricting the rotation range of the engagement body 2. In this way, all the mechanical parts of the crescent lock, including the attachment points to the frame, are incorporated into the mechanism main part a.

FIG. 6B shows a cut-out state for attaching a crescent lock to the combination frame 35 of the inner shoji.
The base seat mounting slot 18 for mounting the mechanism main body part a is provided at two places on the side of the inner frame 35 for the inner shoji. In addition, a handle mounting slot 19 for fixing the rotating shaft 3 and the handle portion b is provided therebetween. Notch 2 for engaging body protruding / retracting on the inner surface of inner frame 35
0, a handle mounting screw insertion hole 21 for fixing the handle 7 and the rotating shaft 3 is provided.

Next, the mechanism main body part a is inserted from above and below the mating frame 35 for the inner shoji, and the base seat mounting screw 1 is inserted.
5 is passed through the elongated hole 18 for mounting the base seat, screwed into the screw hole 10 for mounting the base seat, and fixed so as to sandwich the shape member. Therefore, within the range of the length of the base seat mounting slot 18, the left and right adjustment of the mechanism body portion a becomes possible. The right / left adjustment of the mechanism main body portion a at this time is an adjustment of the pulling direction.

As shown in FIG. 2, the receiving back plate 9 is inserted into the combination frame 34 of the shoji, and the receiving member 8 is screwed in such a manner as to sandwich the profile. FIG. 6-1 shows a cutout of the stile 34 for attaching the shroud 8 for attaching the receiver 8. Two notches 25 are provided at the top and bottom of the receiving mounting notch 25, and receiving notch 26 is provided between the receiving side engaging members. Further, if the notch 25 for mounting is widened in the up, down, left, and right directions, the position of the up, down, left, and right can be adjusted. At this time, the right and left direction is the adjustment of the draw, and the up and down direction is the engagement body 2.
This is adjustment of the degree of engagement between the support 8 and the receiver 8 in the height direction.

FIG. 4 shows the mechanism main body part a and the receiver 8 in the locked state.
FIG. Since the built-in mechanism body portion a is not visible at all from the outside when the crescent lock is assembled, there is almost no need to consider the design. Receiver 8 and engaging body 2
Also, compared to conventional crescent tablets, it is hard to see as incomparably, so there is less need for coloring according to the color of the mold. In other words, these portions can be used as common portions for any color or shape of the sash, so that the number of types can be reduced and the components can be shared.

FIG. 5 shows a mechanism body part a and a handle part b.
It is a side sectional view in the state where it attached to the frame. The mechanism main body part a is fixed to the combination frame 35 of the inner shoji with the two base seat mounting screws 15. Next, the handle-side fitting portion 11 of the handle portion b is fitted into the rotary shaft-side fitting portion 22 having the back of the handle mounting slot 19, and the handle mounting screw 14 is used to remove the handle from the inner surface of the inner sliding door frame 35. It is screwed and fixed to the handle connection screw hole 23 in the frame through the mounting screw insertion hole 21.

Therefore, the part visible from the outside is the handle 7
And only the side of the head of the base seat mounting screw 15. Note that the base seat mounting screw 15 is desirably a flat-head screw. Further, as shown in FIG. 7, the handle 7 is covered with both the base seat mounting screws 15 at the time of locking and unlocking, and is formed in such a shape that the screw head is not visible from the front.

FIG. 7 shows the relationship between the shape of the handle 7 and the base seat mounting screw 15. The base seat mounting screw 15 needs to be loosened even after the handle portion b is mounted for adjusting the drawing direction. Therefore, it is preferable that the setting is made such that the upper and lower two base mounting screws 15 appear simultaneously with the handle 7 rotated 90 degrees. At this angle, the engaging body 2 and the receiver 8 come to the position where they just start to engage, so that the pulling position can be easily adjusted.

However, when the crescent lock is viewed from the side, the side of the head of the base seat mounting screw 15 is inevitably visible. Also, the end of the notched handle mounting slot 19 may be visible when the pulling is adjusted extremely. For these problems, a thin adjusting plate 33 is used as shown in FIG. When the mechanism main body part a is mounted, it is mounted so as to sandwich the mold with the adjustment plate 33. At this time, if the base seat mounting screw 15 is a countersunk head, or if a countersink is applied to a portion of the adjustment plate 33 where the screw head enters, the screw head will not be visible. In addition, the cutout portion of the mold member can be completely hidden by the adjustment plate 33.

Further, by using the adjusting plate 33, the vertical adjustment of the crescent lock can be performed by the mechanism main body portion a. FIG. 10B shows a cutout shape of the inner frame 35 for the inner shoji when the adjustment plate 33 is used. The size of the adjustment plate may be set so that the cutout is hidden so that the cutout can be hidden in any position. In this case, since the vertical adjustment of the receiver 8 is not required, an elongated hole 28 for mounting is provided as shown in FIG. 10A, which can be adjusted only by drawing, and the receiving back plate 9 is not used. May be attached from the inside of the combination frame 34.

In the method of attaching and detaching the handle portion b, the method of attaching and detaching by the fixing method using screws has already been described.
FIG. 8 shows a method of making attachment / detachment easier and one-touch. A catching mechanism is provided in the square-shaft handle-side fitting portion 30 so that the spring 31 allows the ball 31 to come and go. Also, a rotary shaft side square hole fitting portion 29 is provided, and the handle 7
A hole is provided so that the ball 30 can protrude at a predetermined position when the ball is inserted.

Normally, when the handle 7 is fitted, the handle 7 is held by the bias of the spring 32.
When the handle 7 is pulled forward by the force of the spring 32 holding the ball 31 or more, the ball 31 is depressed and the handle portion b can be removed from the mechanism body portion a. Handle part b
When attaching the square shaft-shaped handle-side fitting portion 30, it is only necessary to press the fitting portion 30 to a predetermined position. If the handle portion b is removed after locking the crescent lock and stored in another place, the engagement body 2 cannot be returned, so that higher security can be obtained. The hooking mechanism for attachment / detachment may be not only a method using a spring and a ball, but also any other method. Further, the hooked portion may be on the rotating shaft side instead of the handle side as shown in FIG.

[0025]

The mechanism of the crescent lock is built into the frame of the sash frame, so that the handle can only be seen as if it were in contact with the side surface of the frame, and the sense of unity with the frame was improved. A certain slim shape, etc. is made possible and the design is excellent.

The mechanism part and the handle part are detachable. Since the mechanism part is built in and cannot be seen, the mechanism part is standardized, and by simply changing the design and size of the handle, all kinds of sash windows can be used. Since it is possible to cope, the number of parts can be reduced and the number of parts can be reduced, and it is also advantageous in terms of production management.

In a conventional crescent tablet, a pedestal, which is a relatively large part having a built-in mechanism, is subjected to a surface treatment such as high-grade painting using a die-cast molded product, or a stainless steel is processed to be oxidized and colored. Since the surface treatment is often performed, the proportion of the total cost tends to be high, but since the mechanism part of the crescent lock of the present invention is built in the frame, it is a high-grade for improving the design. No special surface treatment is required, and only anticorrosion treatment is required. Therefore, it can be manufactured at a low cost.

In the type in which the handle portion can be easily attached and detached, it is very effective in terms of crime prevention if the handle is removed and stored in another place when leaving home for a long time. It is impossible to unlock the crescent lock by breaking the window glass near the crescent lock, and the window cannot be opened except by separately preparing the same handle.

Since the mechanism is built in the frame, the thickness of the crescent lock can be made extremely smaller than that of a conventional pedestal. That is, the size of the opening when the window is fully opened can be increased, and the stop piece for preventing the crescent lock from colliding with the sash frame can be reduced.
