Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to closing a window hole by drawing a window plate into the inside of a window hole made through the wall of a building, and then inserting the window plate from the window hole into the wall. This invention relates to an opening/closing device for a protruding elevating window, which opens a window hole by protruding from the outdoor surface of a body and lowering it.

Problems to be Solved by the Prior Art and the Invention Conventionally, such a protruding elevating window opening/closing device has a frame body having a vertical guide rail inside a window hole cut through a wall of a building. The frame body is attached so as to be freely movable between two positions on the outdoor side and the indoor side, and a window plate that closes the window hole is attached to the frame body by its guide rail to an upper position corresponding to the window hole and the window hole is opened. The window board was mounted so that it could be freely raised and lowered between the lower positions, and was suspended by a wire rope that was paid out from a payout device attached to the wall and hung downward by turning a pulley supported by the frame. When opening a window, first the window board is pushed out from the window hole by manually pushing the frame to the outdoor side of the wall, and then the window board is removed by letting out the wire rope from the feeding device. The window is opened by lowering the window, and when closing the window, the winding device winds up the wire rope, raises the window board to the position corresponding to the window hole, and then pulls the frame indoors. The window board was supposed to be pulled inside the window hole, but
Such an opening/closing device has the disadvantage that the window opening/closing operations are complicated because the window panels must be extended and retracted and the window panels raised and lowered by separate operations.

Means for Solving the Problems As a means for solving the above-mentioned problems, the present invention provides a means for solving the above-mentioned problems by installing a vertical guide body inside a window hole cut through a wall of a building, and facing the outdoor side of the wall. The window plate that closes the window hole is attached to the guide body so as to be freely movable between two positions on the indoor side, and can be moved up and down freely between an upper position corresponding to the window hole and a lower position that opens the window hole. The window plate is fed out from a feeding device with a speed suppressing mechanism attached to the wall body, and a rope or chain is turned downward by turning a turning pulley or sprocket supported on the guide body. A biasing device for biasing the guide body toward the outdoor side of the wall body with at least a biasing force greater than the tension acting on the rope or chain due to the dead weight of the window plate is attached to the wall body and the guide body. It was configured to be worn between the body.

Functions and Effects of the Invention The opening/closing device for a projecting elevating window of the present invention has the above-mentioned structure, and when the rope or chain is let out from the feeding device, the guide body moves toward the outdoors by the biasing force of the biasing device, and during the movement of the guide body, , a resistance force against the biasing force of the biasing device acts on the rope or chain, and this resistance force is greater than the tension exerted by the window plate's own weight, so the window plate does not descend relative to the guide body and is placed in the upper position. When the window board is pushed out to the outside of the wall while being maintained at Or, pull out the chain and lower it to the lower position to open the window hole.

When the rope or chain is pulled in by the feeding device in this state, contrary to the above, the window plate first rises and reaches the upper position corresponding to the window hole, and when the window plate stops corresponding to the window hole, the guide body moves. By being drawn toward the indoor side against the biasing force of the biasing device, the window board is drawn inside the window hole and the window hole is closed. This can be done only by letting out and retracting the rope or chain, which has the effect of simplifying the opening and closing operations of the window.

Embodiment 5 An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference character a is a window hole inserted through the wall of the building, and elongated frames 1.1 are fixed vertically and oppositely to the left and right inner peripheral surfaces of the window hole a, respectively. In front of the frame 1, there are upper end portions of guide plates 2.2 which face each other parallel to each other with an interval left and right, and a movable frame formed by passing connecting members 3 and 4 between the upper ends, respectively, and connecting them together. 5 connects each guide plate 2 to a parallel ruler mechanism 6 consisting of two links each.
A guide plate 7 is attached to each frame 1 so that it can move freely in the horizontal direction, and is fixed at right angles to the upper and lower center of each guide plate 2. The guide member 8 fixed to each frame 1 is guided by a guide plate 7. The movable frame 5 is inserted into the hole so as to move stably, and on the front side of the movable frame 5 there are cross-sectional panels attached to both sides of the window plate 11 on which the window glass 10 is fitted. The vertical guide members 12, 12 each having a letter shape are fitted into vertical rails 14 formed on the opposing inner sides of both guide plates 2, respectively, and are mounted so as to be freely movable up and down. On the outside, sprockets 15 and 16 for turning are supported at the upper and lower ends, respectively, and sprockets 17 for hanging are attached to the window board 11 on both left and right sides of the lower end of the window board 11. Each chain 20, which is supported by a support plate 18 and whose negative end is connected to the upper end of each frame 1, is connected to the movable frame 5.
The upper sprocket 15 is turned to hang down, and the hanging portion is turned upward by turning each sprocket 17 of the window plate 11 to suspend the window plate 11, and the lower side of the movable frame 5 is Rotate each sprocket 16 of each frame 1
The lower end of each frame l has an internal sprocket 24 and an external sprocket 2.
A chain case 23 supporting a sprocket 21 that rotates integrally with the frame 1 is attached to each chain case 23, and each chain 20 turned toward each frame 1 is turned to a sprocket 24 in each chain case 23 through a through hole in each frame 1. The ends of each of these free ends are supported within the chain case 23, and the central part of the rear end of the mounting plate 22 is fixed across the upper ends of both frames 1.1. A gear box 25 is attached to the gear box 25, and both ends of an output shaft 26 that penetrates and is supported by the gear box 25 are rotatably supported by brackets protruding from the chainless case 23. The outer sprocket 2 of each chain case 23 is attached to the outside of the chain case 23.
Sprockets 27 corresponding to 1 and 27 are connected to each other, and endless chains 28 are passed between the corresponding sprockets 21 and 27 on both sides, and connected to the gear box 25 via a reduction gear to an output shaft 26. A handle (not shown) is coupled to the protrusion of the input shaft 26, and a damper mechanism for suppressing the rotational speed of the output shaft 26 and a locking mechanism for the output shaft 26 are made of material, and a release button 30 of the locking mechanism is made of the material. protrudes from the top surface of the gear box 25,
When the handle of the gear box 25 is turned, the output shaft 26 is decelerated and rotated through the reduction gear, and this rotation is transmitted to each sprocket 21 connected to the sprockets 27 at both ends through an endless chain 28. The sprockets 24 in the chain cases 23 on both sides rotate, and the chains 20 on both sides rotated by the sprockets 24 are pulled in, thereby driving the window plate 11 upward and retracting the movable frame 5. A door wheel 29 is supported on both sides of the lower surface of the movable frame 5, so that when the movable frame 5 approaches each frame 1, the door wheel 29 rests on the upper surface of the mounting plate 22 at the lower end of both frames 1 and rotates.

A biasing device 31 is installed at an upper portion and a lower portion between each frame 1 and each guide plate 2 corresponding to the front thereof, and this biasing device 31 is connected to a rod inserted into a cylinder 32. 33 is a device in which the rod 33 is urged in a direction to protrude from the cylinder 32 by the pressure of high-pressure gas filled in the cylinder 32, and each urging device 31 is placed sideways.
The base end of the cylinder 32 is connected to the guide plate 2, and the tip of the rod 33 is connected to the bracket 34 protruding from the rear of the frame 1. The movable frame 5 is biased toward the outdoor side of the wall, and when the rods 33 of each biasing device 31 protrude the most, as shown in FIGS. 3 and 4, the front surface of the movable frame 5 Window board 1 suspended by both chains 20.20
