Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a projecting window that is rotatably suspended from the upper frame of the window.

[Prior art]

Conventionally, as shown in Fig. 7, a protruding window is provided in which a shoji is rotatably supported by a horizontal supporting shaft b provided integrally with the upper frame a of the window by means of a hook d protruding from the upper stile c. has been widely adopted. The hook d is simply hooked onto the support shaft b of the upper frame a,
The distance cl between the lower surface of the upper frame a and the upper end of the hook d is small, so that even if the shoji is lifted, it will not come off the window frame.

[Problems to be solved by this idea]

With such protruding windows, as mentioned above, in order to prevent the shoji from coming off the window frame, the shoji cannot be attached to the window frame after the window frame has been assembled, so the shoji must be installed in advance at the factory when assembling the window frame. The hook is inserted horizontally from the end of the upper frame and hooked onto the support shaft. Therefore, if the shoji was damaged during construction on site or after completion, it was not possible to remove or replace the shoji.

Furthermore, if the upper frame is provided with a support shaft, the window frame cannot be used for anything other than a projecting window, resulting in a lack of versatility.

[Means for solving problems]

In the projecting window according to this invention, the support shaft is provided on an attachment that is separate from the upper frame, and the attachment is provided with a projecting piece that projects horizontally from the support shaft on the indoor side, and the upper frame is provided with a horizontal protrusion. An engagement groove opening in the direction and a cover portion extending from the engagement groove toward the outdoor side are formed, and a protruding piece of an attachment that suspends and supports a shoji by hooking a hook on a support shaft is connected to the engagement groove. Engage with the groove and screw the attachment to the upper frame to position and fix the support shaft directly under the cover part of the upper frame, so that the hook of the shoji cannot be removed from the gap between the support shaft and the cover part. The above-mentioned problems are solved by making it possible to attach the shoji to the window frame together with an attachment on-site, and by protruding the window frame so that it can be used for purposes other than windows.

〔Example〕

This invention will be explained in detail below based on the embodiments shown in the figures.

In the figure, a projecting window A according to this invention is provided in a curtain wall unit located in the middle of a curtain wall unit having upper and lower fitting windows B, B.

The window frame forming the curtain wall unit is formed by an upper frame 1, left and right vertical frames 2, 2, and a lower frame 3 framed in a rectangular shape. Panel bodies 5, 5 are fitted into the window frame.

In the projecting window A, a horizontal support shaft 6 is formed on the upper frame 1 to rotatably suspend and support the shoji C, but in this invention, the support shaft 6 is an attachment 7 separate from the upper frame 1. is formed. The attachment 7 is a plate-shaped member, and a support shaft 6 is formed continuously in the longitudinal direction so as to protrude upward on the upper surface of an end that becomes an outdoor end when fixed to the upper frame 1. An enlarged portion 8 having a circular cross section and a diameter larger than the thickness of the lower portion is formed over the entire length of the upper end of the support shaft 6.

The attachment 7 has a projecting piece 9 formed in the widthwise intermediate portion of the base piece 40, which projects horizontally when fixed to the upper frame 1. In the embodiment, a rising piece 10 is formed continuously from the base piece 40 in the longitudinal direction, and the upper end of the rising piece 10 protrudes on the opposite side from the support shaft 6 to form a projecting piece 9.

On the back surface of the base piece 40 on which the support shaft 6 and the projecting piece 9 of the attachment 7 are formed, hanging pieces 10a, 10a are formed in parallel at the opposite end in the width direction and at the middle part thereof and continue in the longitudinal direction.

A stopper 11 is fixed to one side of the support shaft 6. The stopper 11 is L-shaped, and a part of the enlarged portion 8 of the support shaft 6 on the protruding piece 9 side is notched, and one surface 13 is fitted into the notch 12 and abuts against the side surface of the support shaft 6. It is fixed to the other surface 14 by a screw 11a screwed into the attachment 7 from the back surface.

The upper frame 1 has an engagement groove 15 that opens in the horizontal direction;
A cover portion 16 extending toward the outdoor side is formed on the outdoor side of the engagement groove 15 . In the embodiment, the engagement groove 15 is formed facing toward the outdoor side, and the engagement groove 1
A protruding cover portion 16 is formed on the outside of the vehicle 5. Even if the cover part 16 is not in the shape of a protrusion, the lower surface of the hollow upper frame 1 may be used as the cover part 16.

The shoji C has an upper stile 17, left and right stile 18, 18, and a lower stile 19 assembled into a rectangular shape, and the lower surface of the upper stile 17 and the upper surface of the lower stile 19 have panel insertion grooves 20, 2, respectively.
0 is formed, and a panel body 5 such as a glass plate is fitted with a sealing material 21 interposed therebetween. Vertical stile 18,
18 is positioned on the indoor side of the panel body 5, and the panel body 5 is bonded to the outdoor side surfaces of the vertical frames 18, 18 with an adhesive 22 such as structural sealing. 23 is a backup material.

A hook 24 is provided on the upper surface of the upper stile 17 and continuously protrudes upward in the longitudinal direction. The upper end of the hook 24 is bent toward the indoor side to have an arcuate cross section.
The inner diameter of the bent portion 25 is the same as that of the attachment 7 described above.
It is approximately the same as the outer diameter of the enlarged portion 8 of the support shaft 6. A notch 26 is formed in a portion of the bent portion 25 in the longitudinal direction of the hook 24 and on the indoor side. The width of the notch 26 is approximately the same as the width of one side 12 of the stopper 11 described above.

Next, the assembly work of the projecting window having the above structure will be explained.

The attachment 7 is fixed to the upper frame 1 with the hook 24 of the shoji C being hooked onto the support shaft 6 of the attachment 7. When the hook 24 is hooked on the support shaft 6, the stopper 11 is engaged with the notch 26 of the hook 24 to prevent the shoji C from shifting from side to side. Therefore, the shoji C is always in an accurate position and comes into contact with the airtight material of the window frame when closed. The attachment 7 positions the support shaft 6 on the outdoor side, engages the projecting piece 9 with the engagement groove 15 of the upper frame 1, and brings the attachment 7 into contact with the lower surface of the upper frame 1. A screw 27 is screwed through the attachment 7 and the upper frame 1 to fix the attachment 7 and install the shoji C.

When the shoji C is attached, the hooks 24 of the shoji C are located directly below the cover part 16. At this time, the height h from the upper end of the hook 24 of the shoji C to the lower end of the bent part 25 bent toward the indoor side is
4. Reduce cl between the upper end and the cover part 16.
This prevents the hook 24 from coming off the support shaft 6 of the attachment 7, and there is no danger that the shoji C will fall from the window frame.

As described above, the shoji C can be attached to the window frame on site even after the window frame is assembled using the attachment 7.

Furthermore, instead of fixing the attachment 7 on which the support shaft 6 is formed to the upper frame 1, as shown in FIG. The window frame can also be used for folding windows. The shoji C can be tilted outward by a hinge 30 connecting the lower stile 19 and the lower frame 3.

FIG. 5 shows another embodiment in which a draining piece 28 made of soft synthetic rubber or the like is attached downward to the lower surface of the outdoor end of the cover part 16 of the upper frame 1 to drain rainwater. It can also prevent infiltration.

[Effect of idea]

Since the projecting window according to this invention has the above-described configuration, the following effects can be obtained.

○B It is now possible to attach the shoji to the window frame on-site by separating the attachment with the spindle from the upper frame, so even if the shoji is damaged during delivery or construction, it is easy to remove and replace it. It is possible.

○B The support shaft can be attached to the upper frame by fixing the attachment to the upper frame.If the window frame is used for an extending window, an outward-folding window, etc. that does not require a support shaft, a separate attachment is required. It is possible to make the window frame versatile by attaching it or not attaching anything at all.

○C The attachment is fixed with screws with the protrusion engaged with the engagement groove of the upper frame, so the weight of the shoji is supported by the upper frame via the protrusion and the engagement groove, so without applying a large load,
Screws etc. will not be damaged.

○D The space between the hook of the shoji and the cover of the upper frame is such that the hook cannot be removed, so the shoji will not fall off the window frame.
