Description

Detailed Description of the Invention The present invention has developed a unique ingenuity for the support and guide structure of door shoji, and allows the door shoji to be installed without installing any structures that would be distracting, such as door pockets or retractable rails, on both sides of the window frame. This invention relates to a new type of double-hung window that can be smoothly opened and closed to a position where the main body of the window completely moves outside the window frame.

As is well known, door shoji such as rain doors or screen doors installed on the outdoor side of double-door sashes or sliding sashes smoothly guide and support the door shoji when opening and closing from side to side. For this reason, door pockets, retractable rails, etc. are installed on both sides of the window frame, but if such structures are attached to the outer wall of the building, the construction is extremely troublesome and of course increases the construction cost. The appearance of buildings, which tend to have a simple design as modern architecture tends to be, may be seriously damaged. If it were possible to completely open and close the internal door shoji across the entire opening width of the window frame by improving the sash itself, the structure of the sash would be simplified, making construction easier, and the exterior of the building would be completely new. This makes it possible to further emphasize the modern beauty of the building.

The inventor of the present invention focused on this point and, as a result of various research over many years, created an integrated structure that protrudes from the upper and lower frames of both shoji doors toward the upper and lower frame bodies of the window frame at the upper and lower ends of the main body of the left and right door shoji. A projecting wall is provided at one end of the projecting wall, and at one end of this projecting wall, a supporting rod is integrally and continuously extended toward the other door shoji in the opposite direction to the opening driving direction of each door shoji, and the entire length of the upper and lower frames of the window frame is A guide path dedicated to each door shoji that supports the support rods of the left and right door shoji so as to be movable in the longitudinal direction is arranged in parallel, and along this guide path, the main body of the left and right door shoji is approximately extended to the outside of the window frame. The above-mentioned problems are solved at once by a completely exquisite structure that combines the support rods of each door shoji and the upper and lower frames of the window frame so that it can be opened and closed to a completely moving position. The company succeeded in providing a double-hung window with new functions that have never been seen before at a relatively low cost.

Hereinafter, this invention will be specifically explained with reference to the drawings of the embodiments.The double-hung window S1 shown in FIGS. 1A, 1B, and 2 is an implementation structure in which the present invention is applied to a triple-panel window with a heat and soundproof function. This example shows a pair of left and right inner shoji 2a, 2b and a middle shoji 3 within the frames of inner and outer window frames 1a, 1b insulated at the middle.
a, 3b, outer shoji 4a, 4b are fitted,
Of these, inner shoji 2a, 2b and middle shoji 3a, 3b
are formed on a sliding type glass-filled shoji, and the upper and lower rails 5 of the window frames 1a and 1b are formed as in the conventional case.
The left and right shoji are installed along the shoji a and 5b so that only half of the opening area of the window frame can be opened. The structure is such that the entire opening area of the window frame can be opened to a position where the main body of the shoji almost completely moves to both sides of the outer window frame 1b without providing door pockets, retractable rails, etc. on both sides of the window frame 1b. .

That is, in the case of this embodiment, the main bodies 6a, 6b of the outer shoji 4a, 4b are made of a material such as foamed synthetic resin that is relatively lightweight and has good heat and sound insulation properties. Upper and lower frames of shaped cross section 8, 8
A key-shaped projecting wall 1 is constructed by attaching left and right rigid frames 9, 9 of a type cross section, and integrally protrudes from the upper and lower frames 8 toward the upper and lower frames 15, 15 of the window frame 1b.
0 means that the vertical wall 11 is inside the left shoji 4a,
The right side shoji 4b protrudes outward in a slightly offset position, and the left and right shojis 4a, 4b have upper and lower projecting walls 10, 10 provided symmetrically, and the above-mentioned projecting wall 10, 10 extends one end of each shoji so as to protrude toward the other shoji in the opposite direction to the opening drive direction of each shoji, and these projecting walls 10, 1
A suitable number of support rods 12a and 12b are formed integrally and continuously with the support rods 12a and 12b, and the inner support rod 12a projects inwardly, and the outer support rod 12b projects outward. The shafts 13a and 13b are fixed, and door wheels 14a and 14b are attached to the peripheral surfaces of the shafts 13a and 13b, respectively.
is rotatably supported. The window frame 1b that supports the outer shoji 4a, 4b has left and right shoji 4 over the entire length of the upper and lower frames 15, 15 of the window frame.
Guide paths 16a, 16b dedicated to each shoji screen are arranged in parallel inside and outside to guide the support rods 12a, 12b of the supports 12a, 4b in the longitudinal direction, and guide the door wheels 14a, 14b provided on the support rods 12a, 12b. Road 16a, 16
b, and the guide paths 16a, 1
Along the 6b, the main bodies 6a, 6 of the left and right shoji 4a, 4b
Each outer shoji 4a, 4b is supported so that it can be opened as shown by the arrow until the shoji 4a, 4b is moved almost completely to the outside of both sides of the window frame 1b.

In the above embodiment, the left and right outer shoji 4a,
The guide paths 16a, 16b for supporting and guiding the support rods 12a, 12b of the support rods 12a, 12b of the support rods 12a, 12b rotatably support a large number of rollers 17, 17 above and below the guide paths 16a, 16b, as shown in FIG. This roller 1
Support rods 12a and 12b with a rectangular cross section formed integrally with the shoji may be movably inserted between the shoji 7 and 17, and a foamed synthetic resin panel 7 is provided inside the main bodies 6a and 6b of the shoji 4a and 4b. Instead, insect screens or armor plates may be fitted and used as screen doors or rain shutters.

Furthermore, FIGS. 4 and 5 show another typical embodiment of the present invention, and the double-hung window S2 in FIG.
6a, 16b are not arranged in parallel rows at the same height inside and outside, but are arranged in parallel rows up and down with different heights, and door wheels 14a, 14b are attached to left and right shoji screens at different heights.
The double-hung window S3 shown in FIG. 5 has the left and right outer shoji 4a, 4b arranged in parallel in a sliding manner so that the window frame 1b can be completely opened to the outside. An example configured as follows is shown below.
Furthermore, in each of the above-mentioned embodiments, the present invention is applied to a triple-panel window with a soundproof and heat-insulating structure, but the double-hung window of the present invention has glass plates fitted inside the shoji main bodies 6a and 6b, and It is sometimes installed in the opening of a building as a casement window.

As described above, the double-hung window according to the present invention has a unique structure that skillfully supports and guides the double-hung type door shoji, and does not require any distracting structures such as door pockets or retractable rails on both sides of the window frame. Since the main body of the door shoji can be opened and closed smoothly to a position where it is completely moved outside the window frame without having to open or close the door, the structure of the casement window is significantly simplified, its construction is easier, and the appearance of the building is improved. It can be renewed and given a modern aesthetic appearance.
