DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 is a sash for windows, for example, and the sash 1 is provided with a sash frame 2 attached to a frame of an opening of a building. The sash frame 2 is assembled by assembling the left and right vertical frames 2a and 2b, the upper frame 2c and the lower frame 2d, which are made of a shape material such as aluminum alloy, into a rectangular shape by screwing.

In the sash frame 2, in this embodiment, the inside and outside 2
The shoji screens 3a and 3b are attached so that they can be opened and closed horizontally.
It has a so-called sliding shoji construction. Explaining the shoji screens 3a, the shoji screens 3a and 3b are, for example, left and right vertical frames 4a and 4 made of a shape material such as aluminum alloy.
As shown in FIG. 2, the upper frame 4c, the lower frame 4c, and the lower frame 4d are assembled by assembling the glass 6 through the packing 5 made of an airtight material such as rubber or soft resin, and screwing it into a rectangular shape. Has been. The vertical stiles 4a and 4b are concretely the overlapping portions of the door stiles 4a which are in contact with the vertical frames 2a and 2b of the sash frame 2 and the adjacent shoji 3a and 3b when the shoji 3a and 3b are closed. It is distinguished from the fitting frame 4b.

The shoji screens 3a and 3b are provided with pulleys that run on rails formed on the lower frame 2d of the sash frame 2 and crescents that are locking devices. These are the same as existing ones. The illustration is omitted because it is present. Also, shoji 3
In order to ensure the airtightness of the closed shoji 3a, 3b between the a and 3b and the sash frame 2, and between the inner and outer shoji 3a, 3b, for example, as shown in FIG. An airtight material such as a seal member 8 made of, for example, rubber or soft resin provided on the rib 7 on the inner surface is provided.

A lever for forcibly opening the closed shoji 3a which is difficult to open due to wind pressure or the like is provided at a substantially middle portion in the height direction of the door frame (the vertical frame on the closing side) 4a of the external shoji 3a. A shoji opening unit 11 which is a unit including the member 9 and the pressing member 10 is attached. As shown in FIGS. 2 to 5, the shoji opening unit 11 includes a box-shaped casing 12 made of metal such as stainless steel or synthetic resin having a small thickness.

One end (the right end in the illustrated example) of the casing 12 is open, and a flange portion 14 that is in contact with the inner surface of the door end frame 2a is formed on the peripheral portion of the open portion 13. Further, the inside of the casing 12 is divided into an upper chamber 16 and a lower chamber 17 by a partition wall 15, and the other end (the left end in the illustrated example) of the casing 12 has the pressing member 10 housed in the lower chamber 17 in the horizontal direction. A possible opening 18 is formed.

The lever member 9 is rotatably attached to the open portion 13 in the casing 12 via a support shaft 19 made of metal such as stainless steel. The lever member 9 is formed of, for example, a synthetic resin in an approximately L shape, and a portion of the operating side (input side) 9a that rises at a right angle is formed as a handle 20 for opening the shoji 3a. Further, a protrusion 21 is formed at the base of the handle 20 of the lever member 9 so as to extend the operating side 9a of the lever member 9, and the lever member 9 housed in the casing 12 is described later. When the operating side 9a of the above is pulled out from the opening portion 13, it can be easily pulled out by this projection portion 21.

The output end 9b, which is the end of the lever member 9 opposite to the operating side 9a, is formed in a circular shape so that it can slide smoothly when the pressing member 10 is pressed,
The output end 9b is arranged on the lower chamber 17 side in the casing 12, and the support shaft 19 is arranged near the output end 9b. In this way, by disposing the support shaft 19 on the output end 9b side and making the operating side 9a longer than the output end 9b, a large pressing force can be output with a small operating force.

Further, as shown in FIG. 3, the lever member 9 abuts against the end of the partition wall 15 in the casing 12, thereby standing upright in the casing 12 and opening the opening 13.
Is closed (at this time, the handle 20 is stored in the upper chamber 16 side in the casing 12), and the operating side 9
By rotating a from the open portion 13 to the outside of the casing 12, FIG.
When the output end 9b comes into contact with the lower surface of the partition wall 15 as shown in FIG. 5, the operation side 9a is extended to the outside of the casing 12 in a substantially horizontally extended state.
In order to project the operating side 9a of the lever member 9 in the storage position to the outside of the casing 12, the output end 9b of the lever member 9 is used.
It suffices to push in, and thereby the protrusion 21 of the lever member 9
The lever causes the protrusion of the casing 12. A gap s is provided between the output end 9b of the lever member 9 and the pressing member 10 to allow the output end 9b to be pushed.

The pressing member 10 is made of, for example, a synthetic resin in an oval shape so that the lower chamber 17 in the casing 12 has a tip (the left end in the illustrated example) protruding and retracting from the opening 18 to the outside of the casing 12. It is housed so as to be slidable horizontally. Further, in order to allow the pressing member 10 to move in the horizontal direction and prevent the pressing member 10 from falling out of the opening 18 of the casing 12, the pressing member 10
As shown in FIG. 6, projecting shaft portions 22 are provided on both sides of the
On both side walls of the casing 12, elongated holes 23 are formed in the horizontal direction in which the protruding shaft portions 22 are slidably engaged.

When the lever member 9 is in the retracted position as shown in FIG. 3, the pressing member 10 is almost entirely contained in the lower chamber 17 in the casing 12, and as shown in FIG. When 9 is rotated to the operation end position, the tip portion is pushed out to the maximum from the opening 18 of the casing 12 toward the vertical frame 2a of the sash frame 2. Then, as a result of the reaction force by which the tip end portion of the pushing member 10 pushed in this way presses the inner surface of the vertical frame 2a of the sash frame 2 in the left direction in the drawing, the external shoji 3a moves in the drawing as shown in FIGS. It can be opened to the right. In addition, on the inner surface of the vertical frame 2a of the sash frame 2 which is pressed by the tip of the pressing member 10, the pressing member 1 is provided for the purpose of preventing damage or the like of the pressing member 10.
A backing plate 24 made of the same material or hardness as 0 is attached.

The shoji opening unit 1 configured as described above
In order to attach 1 to the door frame 4a of the outer screen 3a, the indoor side of the door frame 4a is formed by increasing the thickness from the glass 6 surface, and the screen opening unit 11 is formed in this portion.
Is formed with an opening 25 for housing the casing 12 of the door frame 4a so as to horizontally penetrate from the inner surface to the outer surface of the door frame 4a,
The casing 12 is attached to the door frame 4a by bringing the flange portion 14 into contact with the inner surface of the door frame 2a and fixing it with the screw 26 in the housed state.

In the sash 1 having the above structure, when the shoji 3a, 3b in the closed state are difficult to open due to wind pressure or the like,
First, as shown in FIG. 3, the output end 9b of the lever member 9 in the storage position is pushed in to project the projection 21 of the operating side 9a from the opening 13 of the casing 12, and the projection 21 allows the operating side of the lever member 9 to be operated. It suffices to further pull the 9a out of the casing 12 and apply a force to the operating side 9a to rotate the support shaft 19 downward as a fulcrum until the operation is completed as shown in FIG.

By the rotation of the lever member 9, the output end 9b
By the lever action, the rear end of the pressing member 10 is pushed, and the front end of the pressing member 10 is pushed out to the maximum from the opening 18 of the casing 12 in the vertical frame 2a direction of the sash frame 2. As a result, the tip portion of the pressing member 10 presses the inner surface of the vertical frame 2a of the sash frame 2 via the contact plate 24, and the reaction force causes the external shoji 3a to be forcibly opened. Since the shoji 9a is forcibly opened by the reaction force of the pressing member 10 pushed out by the lever action of the lever member 9, the shoji 3a, which is difficult to open due to wind pressure or the like, can be easily opened by a simple operation. You can

In this way, if the outside shoji 3a is opened even a little, the inside and outside are communicated as shown in FIG. 5, the pressure difference between the inside and the outside due to the wind pressure is eliminated, and the close contact state of the airtight material such as the seal member 8 is eliminated. So, after that, shoji 3a, 3b
Can be easily opened. In this case, since the handle 20 is formed on the lever member 9, the shoji 3a can be opened as it is without moving the hand.
When closing the shoji screen 3a, the lever member 9 may be housed in the casing 12 and then the shoji screen 3a may be closed.
The pressing member 10 is attached to the inner surface of the vertical frame 2a of the sash frame 2 with a contact plate 24.
It is pushed back into the casing 12 by abutting via the.

In the above embodiment, as a means for preventing the falling of the pressing member 10 while allowing it to move, the pressing member 10 is provided with the protruding shaft portion 22 and the casing 12 is provided with the elongated hole 23.
In contrast to this, the casing 12 may be provided with a shaft and the pressing member 10 may be provided with an elongated hole 27 as shown in FIG. 7, or the pressing member 10 may be simply opened by a stopper or the like. The portion 18 may not be projected beyond a predetermined amount. Further, the shoji opening unit 11 is attached to a substantially middle portion in the height direction of the door frame 4a of the external shoji 3a. The shovel opening unit 11 is mounted at the mounting position of the door frame 4a.
It may be located at any position in the height direction of the sliding door, and the sliding door opening unit 11 may be attached to the door frame 4a of the internal sliding door 3b instead of the external sliding door 3a.
May be attached.

Further, although the handle 20 is provided on the lever member 9, the handle 20 does not necessarily have to be provided.
Further, although the lever member 9 is manually housed in the casing 12, the lever member 9 is automatically housed in the casing 12 by utilizing a force or a spring which pushes the pressing member 10 back when the door is closed. It may be stored. The output end 9b of the lever member 9 is connected to the sash frame 2 via the pressing member 10.
Although the vertical frame 2a of the sash frame 2 is indirectly pressed, the output end 9b of the lever member 9 is directly pressed against the vertical frame 2a of the sash frame 2 without using the pressing member 10 as described below. May be. In addition, the vertical frame 2a of the sash frame 2
The backing plate 24 attached to is not necessarily required.
