Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 This invention relates to a double sliding door device for fittings of buildings such as houses and nursing homes.

[0002]

[Prior art]

 In conventional fittings, double sliding doors are either provided with a groove in the sill that supports the sliding door, or with a door wheel at the bottom of the sliding door and a rail on the sill, so that the right sliding door and the left sliding door are opposed to each other. It was provided at the entrance of a passage or room.

[0003]

[Problems to be solved by the invention]

 If you pull the right sliding door to the right, you can open the entrance to the right by the distance you pull it, but the left sliding door remains stationary. In addition, there was a drawback that the left sliding door had to be pulled to the left to open the left entrance.

[0004]

[Means for Solving the Problems]

 The conventional sill grooves and rails for double sliding doors have been completely abolished, and sliding door hanging brackets have been fixed above each of the right and left sliding doors. The sliding door is suspended by a sliding door hanging bracket so as to be movable left and right, and a pulley is provided on at least one of the upper left and right ends of the sliding door movement, and the other end of the wire having one end fixed to the hanging bracket of the right sliding door is connected to the pulley. If the right sliding door is pulled to the right by hanging, making a U-turn, and fixing to the hanging bracket of the left sliding door, a means is provided to simultaneously pull the left sliding door to the left by wire.

【Example】

 Hereinafter, a detailed description will be given based on the drawings of the embodiments. FIG. 1 is a front view of the double sliding door device of the present invention. The right sliding door 1 is fixed with hanging metal fittings 2 and 3 and a handle 4 is provided. The left sliding door 5 has sliding door hanging brackets 6 and 7 fixed thereto and a handle 8 provided thereon. A frame-shaped rail fitting 9 is fixed to a wall surface 10 above the sliding door, and a roller 14 rotatably supported by the sliding door hanging fitting 2 is engaged with a rail surface 13 of the U-shaped cross section shown in FIG. At the same time, the sliding doors 1 and 5 are suspended from the frame-shaped rail fitting 9 so as to be movable left and right. As shown in FIG. 2, an inverted U-shaped guide frame 15 is provided at the lower portion of the sliding door over the entire width of the sliding door, and a rotatable roller 16 engaged with the inside of the guide frame 15 is provided with a sliding door stopper 17. Then, the steady rest 17 is fixed to the floor surface 20 outside the passage at the left end 18 of the room entrance and the right end 19 of the room entrance shown in FIG.

The pulley 11 is rotatably supported on a support shaft 22 shown in FIG. 3 on the left end wall surface of the frame rail fitting 9, and the support shaft 22 is fixed to the wall surface 10. A wire fixing hole 23 shown in FIG. 2 is provided in the sliding door hanging bracket 2 of the sliding door 1, and one end of a wire (not shown) is appropriately fixed, and the other end of the wire is hung on the pulley 11 shown in FIG. Then, it is appropriately fixed to the wire fixing hole 24 shown in FIG. 2 provided in the sliding door hanging bracket 7 of the sliding door 5.

The operation of the double sliding door device according to the present invention having the above-described configuration will be described. In FIG. 1, if the handle 4 of the sliding door 1 is pulled to the right, the sliding door 1 moves to the right, and at the same time, the sliding door 5 is pulled to the left via the pulley 11 by the wire fixed to the sliding door hanging bracket 2 of the sliding door 1, and the guide frame is provided. When the roller 15 and the roller 16 of the steady rest 17 are engaged, the rail smoothly moves to the left on the rail, and the entrance opens right and left.

Next, when closing the entrance, pull the handle 8 of the sliding door 5 to the right, make a U-turn through a pulley 11 with a wire fixed to the sliding door hanging bracket 7, and simultaneously pull the sliding door hanging bracket 2 of the sliding door 1. Sliding to the left, sliding doors 1 and 5 stop at the center of the entrance and stop, closing the entrance.

If necessary, in addition to the pulley 11 shown in FIG. 1, a support shaft 22 for rotatably supporting the pulley 12 is fixed to the right end wall surface, and the wire fixing hole 2 shown in FIG. 3, one end of a wire (not shown) is fixed, the other end of the wire is hung on a pulley 12, U-turned, and a wire fixing hole 24 shown in FIG. It can also be carried out with the ends fixed. In this case, pulling the handle 4 to the right opens the entrance to the left or right as described above, and pulling the same handle 4 to the left makes a U-turn through the pulley 12 with the wire fixed to the sliding door hanging bracket 3. The sliding door hanging bracket 6 of the sliding door 5 is pulled to the right, and the entrance is closed from the left and right. That is, in this case, the double sliding door device can be opened and closed by operating the same handle 4 or 8 left and right.

The sliding door hanging brackets 2, 3, 6, and 7 are not limited to the configuration shown in FIG. The configuration shown in FIG. 4 can also be implemented. That is, if the roller 26 engaging with the lower surface 25 of the frame-shaped rail fitting 9 shown in FIG. 4 is rotatably supported on the sliding door hanging fittings 2, 3, 6 and 7, the sliding doors 1 and 5 can be further smoothened. You can move left and right. Further, a guide plate 27 is fixed to the lower surfaces of the sliding doors 1 and 5 shown in FIG. 4, a long hole 28 is provided in the guide plate 27 in the width direction of the sliding door, and a run-out engaging with the long hole 28 which moves with the movement of the sliding door. The stopper 29 may be fixed to the floor surface 20 for implementation.

[Effect of the invention]

 In the double sliding door device of the present invention, the frame rail for the sliding door is fixed to the upper part of the wall surface, so there is no obstacle on the floor that prevents the elderly from walking or moving the wheelchair, and it is barrier-free. A sliding door device can be provided. In addition, when the sliding door 1 is pulled to the right by half the width required for passing through the wheelchair, such as when the entrance of the sliding door is opened in a wheelchair, the sliding door 5 automatically shifts to the same distance. Moving to the left, the entrance opens right and left, and the wheelchair can pass through the entrance, making it very convenient. Similarly, if the entrance is open to the left and right, if the sliding door 5 is pulled to the right by half the opening distance and closed, the sliding door 1 will also move to the left half the opening distance and closed. Is closed. In other words, the double sliding door device of the present invention can provide a very convenient double sliding door device in which the opening and closing operation distance of the handle of the sliding door is half that of the conventional double sliding door device, which is a socially beneficial breakthrough. It is a conceptual device.
