Abstract

(57) [Abstract] [Purpose] When the window sliding door is open, the lattice extends to the open part to prevent falling from the window and to prevent illegal intrusion. When the window sliding door is closed, the lattice shrinks. Do not damage the appearance of the windows. [Structure] The front end of a lattice 2 arranged on the outside of a room that expands and contracts by a pantograph mechanism is fixed to the rear part of the indoor shoji 1 in the traveling direction. The front end of the lattice 4 arranged on the indoor side, which expands and contracts by the pantograph mechanism, is fixed to the rear portion in the traveling direction of the outdoor side shoji 3. The rear ends of the lattices 2 and 4 are fixed to the vertical frame of the window frame 5 with bolts 9, respectively. When the indoor shoji 1 is opened, the lattice 2 moves the window frame 5A of the outdoor shoji, and the lattice 4 moves the window frame 5B of the indoor shoji.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a window shoji of a building.

[0002]

[Prior art]

 Conventionally, there is no window shoji with a lattice directly attached to it, and there are those with a lattice fixed to the window frame on the outside of the window shoji and those with a window frame and handrail integrated.

[0003]

[Problems to be solved by the device]

 The lattice fixed to the outside of the window so as to cover the window is very effective in preventing children from falling from the window even when the window is open. In addition, it is effective in terms of crime prevention and can prevent illegal intrusion even with the window open. However, when the windows are closed, the function of the lattice cannot be exerted, which causes the appearance of the building to be impaired. Currently, most of the facilities are not installed except for special facilities. Further, the one with the handrail attached integrally with the window frame has no problem in appearance, but is insufficient in terms of preventing the fall and illegal intrusion.

From the above point of view, the present invention prevents the fall of an infant or the like from the window when the window screen is open and prevents illegal intrusion, and the normal window screen when the window screen is closed. The objective is to provide a window shoji that does not change its appearance and does not impair the appearance.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the window shoji of the present invention has an expandable lattice tip fixed to the rear of the indoor and outdoor shoji in the traveling direction, and the lattice rear end is a vertical frame of the window shoji. The grate fixed and attached to the indoor shoji is movably engaged in the window frame of the outdoor shoji, and the grate attached to the outdoor shoji is movably engaged in the window frame of the indoor shoji. It is characterized by that.

[0006]

[Action]

 The operation of the present invention will be described. When the indoor or outdoor shoji is advanced to the opening side, the rear portion of the indoor or outdoor shoji is opened. Since the expandable lattice is attached to the rear portions of the indoor and outdoor shoji, the lattice is extended to the rear open portion of the indoor or outdoor shoji.

A lattice attached to the outdoor shoji is movably engaged in front of the indoor shoji, and a lattice attached to the indoor shoji is movably engaged in front of the outdoor shoji. Therefore, the indoor and outdoor shoji can be opened until they come into contact with the front lattice.

Therefore, the lattice extends to the open portions of the indoor and outdoor shoji screens, which helps prevent falling and illegal entry. Also, as the indoor and outdoor shoji retract, the respective lattices shrink. Then, when the window shoji is closed, only the reduced lattice attached to the indoor shoji will be visible from the outside slightly along the vertical frame of the window shoji, and it will not spoil the appearance.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of the window shutter of the present invention when it is closed, FIG. 2 is a front view of the window door in the middle of opening, FIG. 3 is a plan view of the same, FIG. 4 is a partially enlarged sectional view of the same, and FIG. It is a rear view.

In the present invention, a lattice 2 that expands and contracts by a pantograph mechanism is provided at the rear of the indoor shoji 1 in the traveling direction, and a lattice 4 that also expands and contracts by the pantograph mechanism is provided at the rear of the outdoor shoji 3 in the traveling direction. There is. Further, the indoor shoji lattice 2 is attached to the window frame 5 on the outdoor shoji window frame portion 5A side, and the outdoor shoji lattice 4 is attached to the window frame 5 on the indoor shoji window frame portion 5B side. It

To install the lattice, pins 6 are provided so as to project on the outdoor side of the rear vertical frame 1A of the indoor side shoji 1 and on the upper side and the lower side of the rear vertical frame 3A of the outdoor side screen 3 on the indoor side. The vertical bars 2A at the tip of the lattice 2 and the vertical bars 4A at the tip of the lattice 4 are respectively attached to the tips of brackets 8 having horizontal slots 7 through which the pins 6 are inserted at the height positions of the pins 6. , The pin 6 is engaged with the long hole 7. The vertical bar 2B at the rear end of the lattice 2 is bolted to the vertical frame of the window frame 5A of the outdoor shoji, and the vertical bar 4B at the rear end of the lattice 4 is bolted to the vertical frame of the window frame 5B of the indoor shoji. It is fixed at 9.

Therefore, when the indoor shoji 1 and the outdoor shoji 3 are opened, the pin 6 inserted into the elongated hole 7 as the indoor shoji 1 and the outdoor shoji 3 are advanced, the tip portion of the elongated hole 7 Move to (forward side) and pull and extend the lattice 2 and the lattice 4. Further, when the indoor shoji 1 and the outdoor shoji 3 are closed, the pin 6 moves to the rear end (retracted side) of the long hole 7 as the indoor shoji 1 and the outdoor shoji 3 retreat, and the lattice 2 and Pull and degenerate the lattice 4.

The length of the long hole 7 is determined by the relationship between the width of the lattice 2 and the lattice 4 when the indoor shoji 1 and the outdoor shoji 3 are closed. When shrinking, the indoor side door 1 and the outdoor side door 3 should be completely closed. Further, a door roller 10 is provided in the lower part of several vertical rails of the lattice 2 and the lattice 4, and a grooved block 11 is provided in the upper portion thereof, so that the door roller 10 of the lattice 2 can be installed in the window frame portion 5A of the outdoor shoji. While being fitted to the lower frame rail 12A, the door roller 10 of the lattice 4 is fitted to the lower frame rail 12B of the window frame portion 5B of the indoor side shoji, and the grooved block 11 of the lattice 2 is the upper frame rail of the window frame portion 5A. 13A, the grooved block 11 of the lattice 4 is fitted to the upper frame rail 13B of the window frame portion 5B, the lattice 2 is in the window frame portion 5A of the outdoor shoji, and the lattice 4 is in the indoor side. It moves in the window frame portion 5B of the shoji screen.

Further, the vertical rails of the grids 2 and 4 have two plate bodies having a U-shaped cross section facing each other in the front and back, and the front and rear plate bodies are screwed 15 through the block 14 at the upper and lower portions. To connect the vertical bars of the grid 2 and the grid 4, the central portions of the equal-length links 16 are crossed at the vertical rails and pivotally attached 17 to the vertical rails, and the ends of the equal-length links 16 are pivotally supported. The pivot 18 is laterally connected by a pantograph mechanism that can move in the vertical rail, and each vertical rail 2A is configured to be expandable and contractable.

[0015]

[Effect of device]

 According to the present invention, when the window shoji is open, the lattice extends to the open part, which prevents children from falling through the window and prevents invasion from the outside. It is effective in crime prevention. Further, when the window shoji is closed, only the lattice of the indoor shoji is present in a contracted state in the corner of the window frame, so that it is not conspicuous and does not spoil the appearance. Therefore, the window can be opened without anxiety even when an infant or the like is allowed to play in the room, which is particularly effective for high-rise apartments.
