Description

[Detailed explanation of the idea] The present invention relates to a satsushi lower frame with an integrated shutter frame.

Japanese Utility Model Publication No. 48-38285, which preceded the filing of the present application, discloses a conventional Domura Satsushi window frame in which a rain door board is integrally attached, but there is a structure in which there is a space between the screen door board and the rain door board. Therefore, it was unavoidable that the depth and width of the lower frame of the satsushi would become extremely large.

In contrast, the present invention is based on a semi-external sash bottom frame, which eliminates the need for such putty space, is effective in dispersing the load of the sash door, screen door, and storm door, and is also effective in distributing the load of the sash door, screen door, and storm door. To provide a sash lower frame with an integrated shutter frame that can be installed in an efficient position.

The present invention will be explained below according to the drawings showing the embodiments.
1 is a sash lower frame with an integrated shutter frame according to the present invention, and this lower frame A is assembled into a rectangular shape together with an upper azalea (not shown) and left and right vertical frames, and a door pocket is integrated on one side of the vertical frame. installed and used.

In the above-mentioned integral sash lower frame A with a shutter frame, a substrate 2 for an inner shoji 1 installed on the lower frame B of a house opening, and a base plate 2 for the inner shoji 1
The boards 2, 4, 6.8 of the board 4 for the outer shoji 3, the board 6 for the screen door 5, and the board 8 for the rain door 7, which are immediately connected to the board 2 for the sliding door 2, are arranged adjacent to each other in a step-like manner that descends forward. shaped substrate 9
is formed.

Projecting rails 10, 11, 12 are provided on the boards 2, 4 for each shoji door 1, 3 and the board 6 for the screen door 5, and the shutter 7
A substantially U-shaped groove rail 13 is formed on the board 8, and guides the opening and closing of each of the shoji 1, 3, screen door 5, and storm door 7, respectively.

From the bottom surface of the board 4 for the outer shoji 3, there is a board 2 for the inner shoji 1.
A downward supporting protrusion 14 is located at an intermediate position between the two, while an L-shaped inward supporting protrusion 1 is located from the lower surface of the shutter 7 substrate 8.
5 are provided protruding from each other.

These supporting protrusions 14 and 15 are integrally connected in the middle of the downward supporting protruding piece 14, and the outer shoji 3 base plate 4,
A stepped hollow reinforcing portion 16 is formed on the lower side of the stepped portion formed by the screen door 5 substrate 6 and the storm door 7 substrate 8 by the lower surface of the stepped substrate 9 and the inner surfaces of each of the supporting protrusions 14 and 15. ing.

Further, the downward supporting protrusion 14 is connected to the lower frame B of the house opening.
is formed so as to be in contact with the outer surface of the

In addition, in the figure, 17 is an L-shaped supporting protrusion installed for the armrest window, 18 is a fixed piece that is the lower part of the downward supporting protrusion 14, 19 is a drainer, and 21 is a connecting block with the door bag bottom frame 20. 22 is the exterior mortar.

Although the embodiments of the present invention have been constructed as described above, the gist of the present invention is to describe the scope of the claims for registration of a utility model, and the present invention is not limited to the above-mentioned embodiments.

The present invention is a sash lower frame with an integrated storm door frame.Based on the semi-external sash, the inner shoji board is installed on the house opening lower frame, while the inner shoji board, the outer sash board, Since the screen door board and the rain door board are arranged in a step-like manner, each board is reinforced by the step-like structure, and the rigidity of the lower frame of the sash is improved compared to a structure in which each board is arranged in a slanted manner. You can improve it further.

In addition, a stepped hollow reinforcing portion is provided below the stepped portion formed by the external shoji substrate, the screen door substrate, and the storm door substrate that protrude outdoors, using the stepped substrate and each supporting protrusion. In addition to improving the rigidity of the lower frame by providing a hollow reinforcing part in the protruding part, the cross-sectional area of each part of the hollow reinforcing part is larger than that of a sloped board that does not have a stepped shape. The resistance to the load of the shoji, screen door, and storm door is increased, and since the stepped hollow reinforcing portion is also formed on the lower side of the storm door substrate, the rigidity of the storm door substrate can be further improved.

Moreover, since the downward supporting protrusion comes into contact with the outer surface of the lower frame of the house opening, these loads can be dispersed over the house.

Furthermore, since each board is adjacent to each other at the front, there is no dead space, which reduces the depth, and since the door opening for the door pocket is located at the location of the board for the storm door, the space required for the door pocket is reduced. A space can be formed between the housing and the outside surface of the house to form a space for an exterior material such as mortar.
