[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a fastening device for a sash including an outer sash and an inner sash, such as a sash with a twill door.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 12 to 14, a fastening device for a sash having an outer sash and an inner sash is used to move a connecting member 21 up and down through a spur gear and a rack by operating a handle 20 provided on the sash. , And the latch 22 is moved up and down in conjunction therewith, so that the outer sash and the inner sash can be opened and closed integrally or separated so that only the inner sash can be closed.

That is, if the handle 20 is at the lower position as shown in FIG.
13 is held down, and the cam 18 of the handle 20 is locked in the frame-side receiver 19 as shown in FIG. When the handle is turned 90 degrees to occupy the horizontal position, the cam 18 is released from its receiver 19 and released, and the latch 22 moves to the position of C1, but retains the receiver 23, and the outer and inner sashes are separated. Kept together.

[0004] When the handle is further turned 90 degrees and placed in the upper position, the latch moves to the position C2, releases the receiver 23, the outer sash and the inner sash are separated, and therefore only the inner sash can be closed. . In such a conventional sash, the maximum dimensions are 800 mm for a shoji width, 1650 mm for a shoji height, and a wind pressure strength of 240 kg / sq.m. Tightening, that is, locking of the sash, as described above, is performed by the cam 18 and the receiver 19 located at the position of the handle.
This was a one-point tightening performed in one place.

[0005]

[Problem to be solved by the invention]
Windows tend to be larger, but with such a single point tightening, if the height of the building is increased and the size of the windows is increased, the wind resistance will exceed the limit, and the height and the size of the windows will increase. I can not cope. For this purpose, it is necessary to increase the number of tightening points. However, since the conventional product has a structure based on one-point tightening, it is impossible to perform multi-point tightening.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art, and to provide a sash tightening device capable of tightening at a plurality of points.

[0007]

The feature of the sash tightening device according to the present invention is that the outer sash and the inner sash are integrally opened / closed by operating a handle provided on the inner sash, or these sashes are separated to form only the inner sash. And a rod 12 provided on the vertical frame of the sash, which is moved up and down by operating the handle, and is fixed at an appropriate position of the rod, preferably at an upper part and a lower part thereof. And a strike 16 installed on the frame side so as to be able to engage with the lock piece. The rod 12 has a notch 6a of a handle latch and a connecting shaft 13 of the rod.
It is moved by engagement with.

[0008]

With this tightening device, the outer and inner sashes can be opened and closed integrally as in the past, the inner sash can be closed separately, and when locked, the lock is locked at the position of the handle. Are engaged with the corresponding strikes 16 and are locked by tightening at a plurality of points.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a cross section of an example of a sash. In FIG.
Are glass sliding doors as outer sliding doors, which are fitted in the frame 3. The door 1 is provided with a handle 4 and each shoji is pivoted on the opposite side of the handle. In this sash, similarly to the conventional case, the ami door 1 and the glass shoji 2 can be opened and closed integrally, and as shown in FIG. 1, these sashes can be separated and only the ami door can be closed. .

Therefore, as shown in FIG. 2, the handle 4 can be turned 180 degrees from below to above.
A spur gear 5 is coaxially fixed to the end of the handle on the mounting side, and the gear rotates together with the handle. Reference numeral 6 denotes a latch for holding a glass shoji receiver, and a spur gear 5 is a latch 6
The rack 7 is provided integrally with the rack 7.

FIG. 3 shows a state in which the latch 6 is mounted. The mounting portion of the latch 6 is formed with an elongated hole 8 extending vertically, and a plurality of shafts 9 which pass through the elongated hole loosely. , And the cover plate 10 is fixed to the door 1. The latch 6 is held by the head of the shaft 9. Rack 7
Is fixed in parallel to the long hole 8 by a screw 11 or the like, and the handle 4 is engaged with the spur gear 5 of the handle and the rack 7.
Is rotated, the latch 6 moves up and down, and the movement is guided by the shaft 9 and the elongated hole 8.

In this tightening device, as shown in FIGS. 2 and 3, the latch 6 is provided with a locking portion or notch 6a. On the other hand, as shown in FIG. 8, a groove is provided in the vertical frame of the glass shoji 2, and a rod 12 is fitted into the groove so as to be vertically movable. Further, as shown in FIGS. 4A and 4B, a connecting shaft 13 is fixed to the rod by a plate 14. This connecting shaft engages with the notch 6a of the latch,
Therefore, the rod 12 moves up and down together with the latch 6.

The upper and lower portions of the rod 12, that is, the handle 4
Locking pieces at appropriate positions above and / or below the
In this example, a roller 15 is attached as shown in FIG.
Further, a strike 16 is fixed to a position corresponding to the roller on the frame 3 side, that is, a position to be engaged with the roller 15 when the sash is locked. FIG. 4 shows the periphery of the handle 4 and the upper part thereof, but the lower part of the handle 4 is similarly provided.
La 15 and strike 16 may be installed.

FIG. 5 shows a state where the glass shoji 2 having the rod 15 and the amidoor 1 are combined.
Is a receiver attached to the glass shoji, which is held by a latch 6 in a locked state. By rotating the handle 4, the latch 6 moves up and down via the spur gear 5 and the rack 7, and at the same time, the rod 12 also moves up and down by the engagement of the connecting shaft 13 and the notch 6 a of the latch. From the state where the handle 4 is in the lower position as shown in FIG.
The latch 6 moves to the position C1 when rotated by 0 degrees, and moves to C2 when further rotated by 90 degrees.

When the handle 4 is in the lower position, as shown in FIG. 6, the latch 6 holds the glass door holder 17, the door 1 and the glass door 2 are held together, and The existing cam 18 and receiver 19 are engaged, and each roller 15 of the rod 12 is engaged with a corresponding strike 16 as shown in FIGS. Therefore, if the roller 15 is located vertically, as shown in FIG. 9, it is locked in a three-point tightening state.

When the handle 4 is turned 90 degrees to move to the horizontal position and the latch 6 moves to C1, the cam 18 at the position of the handle and the receiver 19 are disengaged, and the connection shaft 13 is moved by the movement of the latch. The rod 12 also moves simultaneously, and the respective rollers 15 are released from the corresponding strikes 16 as shown in FIG. 4 (B), but are released as shown in FIG. , The glass door and the glass door are held together.

When the handle 4 is further turned by 90 degrees and moved to the upper position, the latch 6 is moved to the position C2, and FIG.
As shown in FIG. 1, the latch 6 releases the receiver 17, so that the glass shoji 2 is separated from the door 1. Therefore, in this state, it is also possible to close only the door.

In the above embodiment, the outer sash is made of glass sash and the inner sash is made of amidoor. However, it goes without saying that the outer sash and the inner sash may have other structures. . In this embodiment, the upper and lower sides of the handle are also tightened to provide three-point tightening. However, in some cases, the upper or lower side may be provided with two-point tightening. Enables tightening.

[0019]

As described above, according to the present invention, it is possible to open and close the outer sash and the inner sash as a single unit as in the conventional case, and to separate them. Locking by tightening at a plurality of points is possible, so that the wind resistance can be increased. Therefore, it is possible to adapt to the increase in the height of the building and the size of the windows.
