Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a pulling lock for pulling an opening / closing door such as a rotating window or a hinged window to a window frame to lock it.

Conventional technology and problems to be solved by the present invention Conventionally, there are various types of pulling locks for pulling and locking a rotating window or an opening window.
No. 57-123461, No. 59-171173, No. 63-44972
No., etc., the rotary shaft part rotatably attached to the handle support and the handle connected to one end of the rotary shaft part and the other end of the rotary shaft part are connected to each other in a direction perpendicular to each other. And a latch part.

Among these known ones, the latch part has a special shape with a cam surface so as to exert a pulling effect, and many parts are provided between the handle and the latch part, so that the manufacturing cost is low. In addition, the latch part is housed in a special case, and the handle's rotating shaft part is housed in a sleeve, so there are many sliding parts between various parts and smooth operation is possible. In some cases, it may not be pulled and locked. Therefore, the present invention aims to provide an inexpensive pulling lock which is simple in structure and hard to break down.

Means for Solving the Problems A pulling lock according to the present invention comprises a rotating shaft part rotatably mounted on a handle support, a handle continuously provided at one end of the rotating shaft part, and a other end of the rotating shaft part. And a shaft rod portion provided with a latch portion at a front end in a direction perpendicular to the shaft rod portion, wherein the latch portion and the shaft rod portion are integrally formed of a metal rod material. The rod portion and the rotary shaft portion are connected by an engaging means, and the shaft rod portion is rotatably supported at two points in the longitudinal direction which are appropriately separated.

EXAMPLE The invention will be described with reference to the illustrated example. The pulling lock A includes a rotating shaft portion 2 rotatably attached to a handle support 1, and a handle 3 connected to one end of the rotating shaft portion 2. It is composed of a shaft rod portion 5 having a latch portion 4 oriented at a right angle at the tip, and the latch portion 4 and the shaft rod portion 5 are integrally formed of a metal rod material. The parts are connected by engaging means composed of an engaged part 6 and an engaging part 7 which are uneven. Further, the shaft rod portion 5 is a flat plate-like support fitting 8
By means of the through holes of the U-shaped support fittings 9, the support fittings 9 can be freely rotated at two points spaced apart in the length direction.

Then, by rotating the handle 3 shown in FIG. 1 in the direction of the arrow, the latch portion 4 opens and projects into the latch receiving latch receiving hole 11 attached to the vertical frame 10a of the opening and closing shoji, and then the latch receiving hole 11
Slidably contact the cam surface 12 provided obliquely as shown in
Lock in the state shown by the alternate long and short dash line. During this period, the vertical frame 10a is attached to the airtight member 1 of the vertical door stop frame 13 during the sliding contact of the cam surface 12.
It is attracted to the 4th person.

This pulling lock consists of two parts, one on the latch side and the other on the handle side. As shown in FIG. 1, the door stop frame 13 of the vertical frame 10b is sandwiched between and fixed by screws. ing. Then, the screw is to be screwed into a mounting screwing portion provided in the handle support base 1 on the handle side through a mounting hole on the latch portion side.

In this case, the illustrated engaging portion 7 on the side of the latch portion engages with the engaged portion 6 at the tip of the rotating shaft portion 2 on the handle side so that the rotation of the handle 3 is transmitted. Has become.

FIG. 4 is an exploded perspective view of the latch portion side. As can be understood from this figure, the latch portion 4 and the shaft rod portion 5 are made of a metal rod material.

The support fittings 8 and 9 for supporting the shaft portion 5 are rotatably supported at two points appropriately separated in the length direction of the shaft portion 5, as shown in the figure.

To attach the shaft rod 5 to the support fittings 8 and 9, there is a through hole for two-point support in the support fittings 8 and 9 for passing the shaft rod 5 as shown in the drawing. At this time, a collar 15 as shown is incorporated between the two points of support. The collar 15 has substantially the same size as the axial dimension of the space in the illustrated support fittings 8 and 9. Each of the shaft rod portion 5 and the collar 15 is provided with a pin through hole for passing a pin, for example, a spring pin 16 having a C-shaped cross section.

The collar 15 is incorporated in the space of the support fittings 8 and 9, the shaft rod portion 5 is passed through this, and then the pin 16 is inserted through the pin insertion hole and fixed.

On the handle side, a rotary shaft portion 2 is internally provided in a handle support base 1, and a handle 3 is integrally connected to one end of the rotary shaft portion 2. If the rotation shaft 2 is provided with a rectangular head and a leaf spring is pressed against it, the handle will be 90
It is possible to rotate by applying an elastic force so as to restrict the rotation to a certain degree.

The reinforcing piece 17 shown in FIGS. 3 and 4 is provided integrally with the support fitting 9 and, as shown in FIG.
Attach to b with screws. In this way, the support fitting 9
The installation is stable, and the function as a pulling lock can be strengthened. Color as shown in Fig. 4
The one with a pinion described later in 15 can be used.

FIG. 5 shows a retractable lock of the present invention in which a pinion 18 is incorporated, which is adapted to be used, for example, in an opening window elongated in the vertical direction as shown in FIG. In this case, pulling locks can be provided at two positions, upper and lower, so that the pulling effect can be efficiently performed in the vertical direction.

It should be noted that both upper and lower pulling locks A are provided with pinions 18, 18 as shown in FIG. 7, only the lower one is provided with a handle as shown in FIG. 6, and the upper one is only on the latch side.

In addition, the connecting rod 19 and the upper and lower racks 20 are placed between the upper and lower pulling locks A and A.
Is a guide groove 21 on the vertical frame 10b (see FIGS. 2 and 5).
It is attached to the vertical direction so that it can reciprocate vertically.

In this way, if the handle of the lower pulling lock is rotated, it is conducted to the pinion → rack → connecting rod → rack → pinion, and the latch portions of the upper and lower pulling locks A and A can rotate simultaneously.

As described above, the device of the present invention can be used as a single pulling lock, or by using a pinion, a rack, and a connecting rod, it is possible to use two sets of pulling locks at the same time. is there.

Effect of the Invention The present invention has the above-mentioned configuration, and since the latch portion and the shaft rod portion, which occupy most of the lock body, are integrally formed by the metal rod material, the number of components is small. Therefore, it is possible to obtain an inexpensive pulling lock that is hard to break down. Since the rotary shaft is rotatably supported at two points spaced apart in the length direction, the handle can be smoothly rotated even though the rotary shaft is made of a metal rod. Moreover, it can be firmly pulled and locked.
