Description

[Detailed Description of the Invention] The present invention relates to a device for connecting upper and lower frames of a stepped window for a temporary house, which is constructed by stacking a sash frame on top of a sash frame.

Generally, temporary houses have a short assembly and dismantling cycle, so it is important that the step windows of temporary houses can be installed and removed easily and quickly.

However, in the conventional structure of a stepped window, in order to connect the lower frame of the upper sash frame and the upper frame of the lower sash frame, a connecting metal fitting was interposed between the two and screwed together. The work is extremely complicated and the workability is poor, and
Attachment has the drawback that the screws are exposed, spoiling the appearance, and if a batten is attached to hide the screws, the work becomes even more complicated.

Furthermore, temporary houses are often assembled and dismantled in a rough manner, so damage is particularly likely to occur at the connections between the upper and lower frames.
There was a drawback that it caused problems in repeated use.

Therefore, the present invention does not use any screws or battens for installation, and can connect the upper and lower frames extremely simply, quickly, and firmly, and is also easy to disassemble, even if the upper and lower frames are connected and disassembled repeatedly. In order to provide a step window that does not get damaged and has a good appearance, the upper and lower frame connection structure has been specially devised.

That is, the connecting device according to the present invention has two leg pieces hanging down from the lower surface of the lower frame constituting the upper sash frame, and a short leg piece facing the indoor side of the indoor side leg piece at a certain distance. The locking pieces are arranged in a row, the tips of the locking pieces are bent toward the indoor side, the locking pieces and the indoor leg pieces form a downward fitting groove, and the lower part is inserted into the fitting groove. At the same time as inserting the tip of the engagement piece provided upright on the indoor side of the upper frame of the upper frame constituting the section sash frame,
It is characterized in that the legs of the book are secured to the upper surface of the upper frame.

Hereinafter, the present invention will be explained based on illustrated embodiments.

The upper and lower frames constituting the upper and lower sash frames A and B have exactly the same shape, and neither of the sash frames A and B
The lower frame 1 of the upper sash frame A is provided with a hollow part 4 on the lower surface of the stepped inner and outer shoji running parts 2 and 3 toward the indoor side. Leg pieces 5 and 6 are provided vertically on the indoor side of the lower surface of the hollow portion 4 and on the lower surface of the outer shoji running portion 3, respectively, and an overhang horizontally protrudes from the indoor end of the lower surface of the hollow portion 4 toward the indoor direction. At the tip of the section, a short L-shaped locking piece whose lower end bends toward the outdoor side is vertically provided opposite to the indoor leg piece 5, and the locking piece and the indoor leg piece 5 are connected downwardly. It features a fitting groove 7.

In addition, the upper frame 8 of the lower sash frame B has a shoji guide 9.10,
An engaging piece 14 that fits into the fitting groove 7 is provided upright on the indoor end of a substrate 13 on which the fittings 11 and 12 are vertically arranged.

In addition, the two leg pieces 5 and 6 of the lower frame 1 are attached to the lower sash frame B.
As shown in the lower frame 1a, a fitting groove 15 for swallowing the upper end of the panel P is formed, and the engagement piece 14 of the upper frame 8 is formed as shown in the upper frame 8a of the upper sash frame A. It also has the function of engaging and supporting the interior surface of the lower end of the panel P.

Therefore, in constructing the stepped window, the tip of the upper frame engaging piece 14 of the lower sash frame B is fitted into the lower frame fitting groove 7 of the upper sash frame A, and the lower frame legs of the upper sash frame A are fitted. pieces 5, 6
The upper frame 8 and the lower frame 1 are firmly and immovably connected by fitting the engagement piece 14 into the fitting groove 7, and the lower frame 1 is fixed to the upper base plate 13 of the lower sash frame B. book leg piece 5
, 6 on the upper frame 8,
In addition, since no screws are used for installation at all in the polymer connection of the two, it has the advantage that the connection or disassembly of the two can be done extremely easily and quickly, and it also gives a good appearance. Give.

Furthermore, since the fitting groove 7 is provided downward in the lower frame 1, dust etc. blown in when the shoji is opened will not accumulate in the fitting groove 7, so that the upper frame 8 and It has the effect that the bottom frame 1 can be reliably stacked vertically without causing any trouble in connecting and fitting the bottom frame 1, and the tip of the locking piece that makes up the fitting groove 7 is bent to improve rigidity. Therefore, even if the upper and lower frames 1 and 8 are repeatedly connected and disassembled when assembling and disassembling the step window, there will be no damage, and the opening of the fitting groove 7 will always be kept constant, and the upper frame 8 will not be damaged. This has the effect of reliably and easily fitting the engaging piece 14.
