Description

[Detailed description of the invention] The present invention relates to an opening/closing device for windows such as revolving windows and projecting windows, which can open/close shoji and attract the shoji to the window frame after closing the window by operating a bundle. The aim is to provide equipment.

Hereinafter, the structure of the present invention will be explained in detail with reference to the drawings showing one embodiment.

Reference numeral 1 denotes a bundle, which is attached to a bundle rod 2 at right angles, and the bundle rod 2 is inserted into a bundle rod insertion tube 3.
A pin 5 passing through the elongated hole 4 of the insertion tube 3 is installed so as to be rotatable and non-removable.

The bundle rod insertion tube 3 is rotatably supported on a seat plate 7 fixed to the window frame 6 by a shaft 8.

Reference numeral 9 denotes an interlocking mechanism case, which is fixed to the shoji 10, and includes a pinion 11 and a pair of rack plates 1 that mesh with the pinion 11.
2.12 is provided.

A rotating shaft 14 that protrudes from the front of the case 9 and has a square cutout groove 13 is connected to the pinion 11, and each rack plate 12.
12 is provided with an actuation piece 15 that protrudes toward the rear of the case 9.

A square shaft portion 16 is formed at the tip of the bundle rod 2 and engages with a square notch groove 13 of the rotating shaft 14.

Reference numeral 17 denotes an arm, one end of which is supported by a shaft 18 in the bundle rod insertion tube 3, and the other end supported by a bearing piece 19 of the actuation mechanism case 9.
It is removably attached to via a shaft 20.

That is, the bearing piece 19 is fitted and attached to the small diameter portion 22 of a shaft 20 which is protruded from the arm 17 by a spring 21, and is detached from the bearing piece 19 when the shaft 20 is retracted.

Reference numerals 23 and 23 are sliding rods that operate a pulling mechanism, etc., and are slidably fitted to the lower frame 24 of the shoji 10, respectively.
An actuation pin 25 provided on the top surface engages with a notch 26 of the actuation piece 15.

Reference numeral 27.27 is a drawing body, which has a protruding part 28 and an inclined part 29, and is fixed to the window frame 6.

A protrusion pin 30 provided on the lower surface of the sliding rod 23 is slidably engaged with and disengaged from the protruding portion 28 of the attracting body 27.

Next, the effects of the present invention having the above-mentioned configuration will be explained with reference to FIG.

FIG. 2 shows the shoji 10 in its closed state from the open state, with the rotating shaft 14 in a position where the opening of the square notch groove 13 faces downward, and the operating piece provided on the rack plate 12.12. 15.15 are slid to positions close to each other, and each sliding rod 23 connected thereto is also slid in the same direction.

Further, the attracting pins 30 provided on each sliding rod 23 are also removed from the attracting bodies 27, and the shoji is not attracted.

In this state, when the handle 1 is rotated in the circumferential direction of the handle rod 2, the actuating pieces 15.15 slide in a direction away from each other via the rotating shaft 14, pinion 11 and rack plate 12.12. The sliding rods 23 connected to the sliding rods 23 slide in the same direction, and the drawing pins 30 are guided by the inclined parts 29 of the drawing bodies 27 and engage with the protruding parts 28, and the shoji 10
is attracted toward the window frame 6.

Also, in the state shown in Fig. 2, the handle 1 is attached to the handle rod 2.
When the handle rod 2 is rotated in the direction of the shoji 10 around the shaft 8 through the
When the shoji 10 is pushed out by the arm 17 connected to the handle rod insertion tube 3, the rotating shaft 14 is moved to the corner shaft of the handle rod 2. 16 and is fenestrated.

In this state, when the arm connecting shaft 20 is retracted against the spring 21, the arm 17 comes off from the bearing piece 19, so that the shoji 10 can be further opened manually.

In the embodiment, a pinion rack is used as a mechanism for interlocking the rotating shaft 14 and the sliding piece, but the present invention is not limited to this, and for example, a link mechanism or the like may be used.

In addition, as an engagement structure between the handle rod and the rotation shaft, in the embodiment, a square notch groove was formed on the rotation shaft and a square shaft portion was formed at the tip of the handle rod. A structure in which a square shaft portion is formed and engaged with each other may also be used.

In this case, it goes without saying that the position of the notched groove must be upside down.

Further, the mechanism operated by the sliding piece is not limited to the attracting mechanism, but may also be a locking mechanism.

As described above, the present invention allows the shoji to be easily pulled toward the window frame by rotating the handle in the circumferential direction of the handle rod when the window is closed. The window can be opened by rotating it so that it stands up, and its major feature is that these operations can be performed with a single handle.

Claims (1)

[Scope of utility model registration request] A bundle rod 2 having a bundle 1 is rotatably attached to a bundle rod insertion tube 3 rotatably attached to a window frame 6,
On the other hand, the shoji frame 10 has a sliding rod 23 that operates a pulling mechanism, etc.
A rotating shaft 1 that interlocks the sliding rod 23 by rotating with
4, and the rotation shaft 14 is engaged with the bundle rod 2 by forming a square notch groove on one side and a square shaft part on the other side so that the bundle rod 2 can be separated when the pulling mechanism etc. are not activated. The window opening/closing device is further characterized in that the bundle rod insertion tube and the shoji frame are connected to each other by an arm 17 that is pivotally supported.
