Description

[Detailed Description of the Invention] The present invention relates to an inner sash mounting structure for retrofitted double-glazed windows.

In retrofitted double-glazed windows in which an inner sash is retrofitted to an opening in the frame where an outer sash is already installed, the inner sash is usually attached by attaching a framed window frame to the opening in the frame.

However, since the dimensions of the frame opening vary depending on the region, it is necessary to manufacture an inner sash that matches the dimensions of each frame opening, which increases the number of parts and makes production and inventory management troublesome. I become confused.

The present invention was developed in view of the above circumstances, and its purpose is to provide an inner sash for a retrofitted double-glazed window that can be reliably installed even if the dimensions of the frame opening differ.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a longitudinal cross-sectional view, and FIG. 2 is a cross-sectional view.
The frame opening A has a rectangular shape with a lintel 1, a sill 2, and left and right pillars 3, 3.

B is an outer sash attached to the outside of the frame opening A, and a window frame 7, which has a rectangular shape from the upper frame 4, lower frame 5, and left and right vertical frames 6, 6, is attached to the outer side of the frame opening A, and Inside the window frame 7, outer and inner shoji screens 8 and 9 are installed alternately.

C is an inner sash installed inside the frame opening A, which includes an upper frame 10, a lower frame 11, and left and right vertical frames 12, 1.
Inner and outer shoji 14, 15 are installed in a sliding manner in a window frame 13 which is framed in a rectangular shape.

The upper frame 10 has upper and lower walls 16, 17 and outer and inner walls 1.
8 and 19 form a hollow shape, and an upper rail 20 is integrally formed on the lower wall 17, and the upper wall 1
6 is bent into a substantially crank shape to form an outward stepped portion 21, and an upwardly directed groove 22 is formed at a position near the outside of the upper frame 10.

The lower frame 11 has upper and lower walls 23, 24 and outer and inner walls 2.
5 and 26 form a hollow shape, a lower rail 27 is integrally formed on the upper wall 23, and the lower wall 24 is bent into a substantially crank shape to form an outward step 28, and the outer side of the lower frame 11 A downward groove 29 is formed at the offset position.

The vertical frame 12 has left and right walls 30, 31 and outer and inner walls 2.
2 and 33, the right wall 31 is bent into a substantially crank shape to form an inward step 34, and an outward groove 3 is formed at the outer side of the vertical frame 12.
5 is formed.

Reference numeral 40 denotes an upper mounting member, which includes a vertical piece 41 facing into the upward groove 22 of the upper frame 10 and a mounting piece 42 attached to the inner surface 1b of the lintel. A mounting groove 43 is formed therein.

Reference numeral 50 designates a lower mounting member in which horizontal pieces 52 and 53 are formed on the upper and lower sides of a vertical piece 51, and a rising piece 54 is formed on the upper horizontal piece 52. The elastic member 55 is fitted into the groove 29, and a mounting groove 56 for the elastic member 55 is formed to open outward.

Reference numeral 60 denotes a vertical mounting member, which is approximately L-shaped with a vertical piece 61 that fits into the outward groove 35 of the vertical frame 12 and a mounting piece 62, and the vertical piece 61 has a mounting groove 64 for the elastic material 63 on the outside. It is formed with an opening.

Therefore, in order to attach the window frame 13 inside the frame opening A, first, the vertical piece 51 of the lower attachment member 50 is fixed to the inner wall 5a of the lower frame 5 with screws 70, and then attached to the sill 2.

On the other hand, the upper frame upward concave groove 22 of the framed window frame 13
The vertical piece 41 of the upper mounting member 40 is inserted and fixed therein via an elastic member 44 so as to be movable up and down, and the vertical piece 61 of the vertical mounting member 60 is inserted into the vertical frame outward concave groove 35 via an elastic member 63. Insert and fix it so that it can be moved left and right.

Then, the window frame 13 is built into the frame opening A so that the lower frame downward groove 29 is fitted into and fixed to the rising piece 54 of the lower mounting member 50 via the elastic member 55.

Thereby, the window frame 13 is positioned in the inside-outside direction and in the up-down direction.

At this time, upper and lower elastic members 45,
57 and a vertical elastic member 65 are provided, and the upper and lower elastic members 45, 57 are pressed against the lintel inner surface 1a and the sill inner surface 2a, and the vertical frame elastic material 65 is pressed against the column inner surface 3a.

In this state, the mounting piece 42 of the upper mounting member 40 is fixed to the lintel inner surface 1b with screws 71, and the mounting piece 62 of the vertical mounting member 60 is fixed to the column inner surface 3b with screws 72.

At this time, the upper mounting member 40 moves up and down along the upward concave groove 22 according to the vertical dimension of the body opening A, and the vertical mounting member 60 moves outwardly in accordance with the horizontal dimension of the body opening A. It moves left and right along the groove 35.

As described above, even if the vertical and horizontal dimensions of the frame opening A are different, the window frame 13 can be reliably installed, and the window frame 13 can be made common, reducing the number of parts and making manufacturing and inventory management easier. It becomes easier.

In addition, since the window frame 13 is attached to the frame opening A through each of the elastic members 44, 55, 64 and 45, 57, 65, it can be attached firmly and stably, and there is no gap in the attachment part. Foreign matter such as dust does not enter the mounting portion (that is, between the frame opening A and the window frame 13).

The present invention is as described above, and even if the dimensions of the frame opening A are different, the installation can be ensured, and the elastic materials 45, 56 are provided between the upper and lower frames 10, 11 and the vertical frame 12 and the inner surface of the frame body opening. 65, it can be mounted stably and reliably, and foreign substances such as rubber will not enter the mounting part.
