Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a window structure useful for smoke exhaust windows, ventilation windows, etc. of buildings.

Conventionally, windows that open and close in the vertical direction, which are used for smoke exhaust windows and ventilation windows, have a rigid frame 1 of the window as shown in Figure 1.
Upper and lower protrusions 2 and 3 are provided, and the frame 4 is provided with a groove 5 in which the protrusions 2 and 3 slide.
There is also a diagonal groove 6 that keeps the window open.
There are grooves a and 6b, and the window is structured to move up and down to open and close according to these grooves.

According to this structure, the frame 4 must have a thickness equivalent to two windows, and the frame must be approximately twice the height of the window, which is extremely difficult for the size of the window. This has the drawback that the frame becomes large and the opening of the structure also becomes large accordingly.

The present invention aims to solve the above-mentioned drawbacks, and has one vertex of a triangular support having three vertices attached rotatably to the upper, middle or lower part of the window frame, and the other two vertices A protrusion is provided on the structure, and this protrusion is fitted into a groove in the frame. When opening the window, the window protrudes outside the wall of the structure and descends. This reduces the possibility of the frame being damaged. It is characterized by a window structure that can be small in size.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

Reference numeral 7 denotes a dogleg-shaped or roughly triangular supporting metal part, whose one vertex is rotatably supported by a shaft 9 on the window's rigid frame 8, and protrusions 10, 11 is installed protrudingly. Such supporting metal fittings 7 are rotatably attached to the upper and middle portions of the left and right frames as described above.

Reference numeral 12 denotes a groove formed in the frame 13, in which inclined grooves 14 and 15 are continuously formed upward toward the indoor side at the upper and middle portions.

Reference numeral 16 denotes an operating wire with one end fixed to the upper end of the rigid frame 8, and the other end wound around a drum 18 connected to a drive source such as a motor via a pulley 17.

Therefore, the solid line in FIG. 2 shows the window closed, the protrusions 10 are accommodated in the inclined grooves 14 and 15, the protrusion 11 is located in the groove 12, and the operating wire 16 is wound up by the drum 18. They keep the windows open.

To open the window from the above state, rotate the drum 18 and loosen the operating wire 16, and the window will begin to descend due to its weight, at which time the projection 10 will follow the inclined grooves 14 and 15. sliding,
Accordingly, the window is rotated by the shaft 9 and protrudes outside the wall, and the window continues to descend with the protrusion 10 entering the groove 12 as shown by the dashed line, and the window is attached to the support metal fitting 7. It is supported and descends parallel to the wall surface. After lowering the window to the desired position, turn drum 1
Stop the rotation of 8 and maintain the open state.

To close the opened window, the drum 18 is driven to wind up the operating wire 16 to raise the window. The protrusions 10 and 11 move along the grooves 12 and the window rises, and the protrusions 10 move along the inclined grooves 14 and 15. As the projection 10 enters the end of the inclined grooves 14 and 15, the window rotates by the shaft 9 and approaches the frame 13.
3 as shown by the solid line, and the operation wire 16
The window is held and locked by stopping the drum 18.

Note that various methods can be considered for forming the inclined groove and the lower end stopper in the above embodiments. For example, the block may be fixed to the frame material in which the groove is formed so as to form the inclined groove; A large block with inclined grooves formed thereon may be fixed to the frame material, or a structure may be employed in which the grooves and inclined grooves are integrally formed in the entire frame.

The window is operated by an operating wire wrapped around a drum, and this drum is connected to a drive source such as a motor as described above, but a crank or the like is attached so that the drum can be rotated manually. Furthermore, the drive source may be electrically connected to a smoke detector or the like so that smoke evacuation can be performed automatically in the event of a fire.

Further, the protrusion in the above embodiment may be a rotatable roller on the supporting hardware, or may be a roller having a U-shaped sliding surface in cross section, and the groove of the frame may be a corresponding rail.

According to the present invention having the above-described configuration and operation, the supporting metal piece having three vertices that moves in the groove is rotatably attached to the window stile, so that when the window is opened, it is supported by the supporting metal piece. As the window moves down the outside of the wall parallel to the wall surface, the window will come out of the frame. Therefore, the frame size may be small and the height of the frame may be low, resulting in an inexpensive window structure.

Furthermore, since the function of the window to open and close by moving up and down is similar to that of conventional windows, it is extremely useful as a smoke exhaust window and a ventilation window.

Claims (1)

[Claims] 1. In a vertically movable window structure in which the end of the operating wire wound around a drum connected to the drive source is attached to the upper end of the rigid frame, and the window is opened and closed by the rotation of the drum, the upper part of both rigid frames of the window and A V-shaped or roughly triangular supporting metal piece is rotatably attached near one apex at two places in the middle, and protrusions or rollers provided near the other two apexes of this supporting metal piece are connected to grooves provided in the frame. A window structure characterized in that the window structure is fitted into the window and is provided with an inclined groove upward toward the indoor side at the upper and middle portions of the groove.
