Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a support fitting for attaching a panel lattice to an aluminum sash window installed in a concrete wall such as a so-called RC wall or an ALC wall.

(Prior art) As shown in FIG. 3, the conventional support fitting 1 of this kind has a short piece 5a which is fixed to the inward flange 3 of the vertical sash frame 2 with screws 4, and a short piece 5a which is fixed to the horizontal bar 7 of the surface lattice 6 with screws 8. Since the structure is such that the long piece 9a faces the long piece 9a, the L-shaped large and small bending pieces 5 and 9 are constructed in combination so that the long piece 9a does not interfere with driver operation when the short piece 5a is screwed. When attaching the surface grating 6, first the short piece 5a of the small refracting piece 5 was fixed to the inward flange 3 with screws 4, and then the large refracting piece 9 was fixed to the small refracting piece 5 with screws 10. This not only increases the cost of assembling them as a pair, but also requires additional assembly work, which makes it time-consuming to install the grid.Furthermore, the assembly screws 10 are visible from the outside, making it easier to operate with a screwdriver to loosen the screws 10. Therefore, there was a drawback that it was inconvenient in terms of crime prevention.

(Purpose of the invention) This invention solves the above-mentioned drawbacks.
The purpose of the present invention is to provide a support fitting that, although integrally molded, can be screwed to the inward flange of a vertical frame without any problem, and can be used to attach a surface grid that cannot be easily removed from outside the window. It is.

(Structure of the invention) In order to achieve the above object, the present invention is a support that has a U-shaped bent integral shape with long and short pieces facing each other, and a hole for operating a screwdriver is provided at the base end of the long piece. The purpose is to suggest metal fittings.

(Example) Next, an example of the present invention will be described with reference to FIGS. 1 and 2.

The support fitting P is integrally formed by bending a single iron plate, and has a substantially U-shaped bent shape with a short piece 11 and a long piece 12 facing each other and a connecting piece 13 between them. A pair of through holes 15 for screws 14 are provided, and a pair of left and right screws 16 are provided in the long piece 12.
A through hole 17 is provided.

In addition, a pair of upper and lower holes 18, 18 are provided in the bent part of the base end of the long piece 12 for operating the screwdriver.
The through holes 15, 15 are provided at the height positions corresponding to the through holes 15, 15, and the extraction holes 18, 18 are formed across both the long piece 12 and the connecting piece 13, so that both the extraction holes 18, 18
In between, a rib 19 is formed by punching out the inner corner.

An aluminum sash 22 is fitted into the window 21 where the concrete wall 20 is opened, and the sash vertical frame 23
It has an inward flange 24 at the outdoor end that extends toward the inside of the frame. Moreover, the surface lattice 25 is made up of a large number of vertical bars 27 arranged in a row on the upper and lower horizontal bars 26, 26 and secured with screws.
The horizontal beam 26 has a substantially C-shaped cross section, and a groove 28 is opened on the indoor side surface.

Therefore, when attaching the surface lattice 25 using the support fittings P, first fix the short pieces 11 to the inward flange 24 of the vertical frame 23 with the screws 14, and then attach the horizontal bars 26 of the surface lattice 25 to the long pieces 12 with the screws 16. Attach. However, even if the screws 14 are screwed directly into the inward flange 24 of the vertical frame 23, the mounting strength is not reliable due to the material, so it is preferable to use the auxiliary plate 29 having female threads 35. Further, since the horizontal bars 26 of the surface lattice 25 have a C-shaped cross section, an auxiliary plate 30 that hangs on the inside of the groove 28 is used to fasten the horizontal bars 26 with screws.

In any case, the short piece 11 is connected to the inward flange 24.
When fastening with the screws 14, a screwdriver can be inserted into the extraction hole 18 and the screw 14 can be operated. However, when the face grating 25 is attached, the extraction hole 18 is crushed by the horizontal bar 26, and the screwdriver can be inserted into the extraction hole 18. Since the screw 14 cannot be inserted, the screw 14 cannot be operated from the outside.

In addition, attach the horizontal bar 26 of the surface lattice 25 to the long piece 12 with screws 1.
When stopping at 6, the short pieces 11 do not interfere with the driver's operation, so the face grill 25 can be easily installed, but once the face grill 25 is installed, the screws 16 are hidden behind the horizontal bars 26 and cannot be seen from the outside. ,
Since it is difficult to operate the screwdriver because it is supported by the screen door 31 or the shoji 32, the screw 16 cannot be removed from the outside in this case as well.

Note that if the connecting piece 13 of the support fitting P is joined to the inner peripheral surface of the window of the concrete wall 20, the surface lattice 25
Provides stability that prevents it from shaking from side to side.

Further, by joining the connecting piece 13 to the inner circumferential surface of the window in this manner, the door end groove 34 of the vertical stile 33 of the screen door 31 can be deeply accommodated in the inward flange 24. Regarding this, a conventional support fitting 1 as shown in FIG.
In this case, since the connecting part between the short piece 5a and the long piece 9a was double thick, it was not possible to insert the door end groove 41 of the screen door 40 deeply, but in this embodiment, the door end groove 41 was made in a single layer, so the door end groove 41 could not be inserted deeply in this embodiment. The groove 34 can be deeply seated in the inward flange 24.

(Effects of the invention) The support metal fittings for installing the surface lattice according to the invention are as follows:
As explained above, the short piece fastened to the inward flange of the vertical sash frame with screws and the long piece fastened to the horizontal crosspiece of the face lattice with screws face each other. At the end, there is a hole for operating a screwdriver that screws the short piece at the position where the horizontal crosspiece of the face lattice hits, so it can be easily screwed to the inward flange of the vertical sash frame. Once installed, it is extremely difficult to loosen the screws, and the grid cannot be easily removed from the outside, making it extremely safe from a crime prevention perspective. In addition, since the troublesome work of assembling short pieces and long pieces is not required, it is easy to attach the surface grid, and the integrated molding allows for mass production and provides advantages such as being inexpensive.
