Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermal insulation type shoji using a horizontal frame made of a metal frame and a resin frame covering a portion of the metal frame exposed on the indoor side.

[0002]

2. Description of the Related Art A thermal insulation type shoji as described above comprises a metal frame,
It is used when a composite sash is constructed by being built on a window frame composed of a resin frame that covers a portion of the metal frame exposed on the side of the metal frame. This kind of composite sash includes Jikken 63-4
No. 9481, JP-A-8-177316 and JP-A-8-178316
Japanese Unexamined Patent Publication No. 177317 is known, which has both weather resistance and strength of a metal material and heat insulation and a design property of a resin material, and matches the exterior and interior with the exterior and interior of a building, respectively. Is being adopted not only in cold regions but also in non-cold regions.

[0003] By the way, in the vertical frame of the heat insulating type shoji, when the shoji is closed, the entire length of the vertical frame is fitted in the groove.
Although it has the strength to withstand strong positive or negative pressure such as typhoons, only the upper or lower part of the horizontal frame such as the upper frame or the lower frame has airtight material on the upper rail or the lower rail. Alternatively, it is merely relatively loosely fitted and supported via a door wheel and an airtight material. Therefore, since a strong wind pressure is apt to be applied, a considerable strength is required for a connection state between the metal frame and the resin frame.

[0004]

However, since the resin frame is poor in impact resistance, when connecting the metal frame and the resin frame with screws or the like, it is necessary to provide a screw through hole in advance on the resin frame side. is there. Therefore, the conventional heat-insulating sash to be joined with screws or the like requires a joining member such as a screw, processing of a through hole, positioning and screwing of the screw or the like, and therefore, the manufacturing cost increases. The metal frame is formed of an aluminum alloy or the like, and the resin frame is formed of vinyl chloride, acrylic, or the like, and has different thermal expansion and contraction rates. Therefore, in the case of coupling through a screw or the like, unless the screw through hole is formed in consideration of the expansion and contraction ratio, inconveniences such as breakage of the screw through portion due to thermal expansion force are likely to occur.

[0005] In order to avoid such difficulties, one of a metal frame and a resin frame is provided with a fitting groove, and the other is provided with an edge which can be fitted in the fitting groove by two frames separated from each other in the height direction of the frame. Formed over the entire length in place, butting the two frames, fitting the pair of fitting grooves and the edges, and then joining the other pair of fitting grooves and the edges by fitting them closer together. A horizontal frame that does not use screws, etc. is adopted.

[0006] However, since the connection is formed by such two pairs of fittings, the bonding strength is limited, and when a strong wind pressure or the like is applied to the horizontal frame, the fitting state deteriorates. There was a risk of distortion or deformation.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to provide a horizontal frame of a heat-insulating type shoji which can easily connect a metal frame and a resin frame at a low cost and with a reliable connection strength. It is an issue.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a heat insulating type shoji using a horizontal frame composed of a metal frame and a resin frame covering a portion of the metal frame exposed on the indoor side. Forming a fitting groove that opens in the resin frame direction in the height direction intermediate portion of the metal frame, and providing a coupling edge extending in the metal frame direction in the height direction intermediate portion of the resin frame, The connection edge is fitted in the fitting groove, and the protruding edge forming the fitting groove is caulked at a plurality of locations to connect the metal frame and the resin frame. According to the above configuration, since the protruding edge is caulked in a state where the joining edge of the resin frame is fitted in the fitting groove of the metal frame, the joining strength between the joining edge and the fitting groove is remarkably enhanced, and Even if a force such as a strong wind pressure is applied to the substrate, the combined state does not deteriorate. Unlike the related art, since accurate processing of the screw hole and screwing of the screw are unnecessary, there is no cost and there is no possibility of damage around the screw hole.

[0009] The metal frame has a tubular portion for providing strength,
Extending vertically from one side surface of the cylindrical portion, and having upper and lower wall portions constituting one side wall of a rail fitting groove and a glass fitting groove, respectively, and forming the cylindrical portion on one of the walls. At a position close to one of the webs, a protruding edge extending parallel to the web is formed, and a fitting groove is formed between the web and the protruding edge. It has upper and lower walls that constitute the other side wall of the groove and the glass fitting groove, is overlapped between the two walls with the web of the metal frame, and the tip fits into the fitting groove of the metal frame. In the state where the joining edge of the resin frame is fitted in the fitting groove of the metal frame, the protruding edge is pressed and deformed at a plurality of locations separated in the longitudinal direction, The joining edge of the resin frame is fixed between the web of the metal frame and the projecting edge. It is desirable to have. According to the above configuration, since the joining edge is firmly held between the swaged protruding edge and the web forming the strong cylindrical portion, the joining strength between the resin frame and the metal frame is further increased.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a sliding door according to an embodiment of the present invention; The present invention can be applied almost similarly to the horizontal frame used for the lower frame. 1 is a sectional perspective view of the upper part of a shoji, FIG. 2 is an exploded front view of only the metal frame of FIG. 1, FIG. 3 is a longitudinal sectional view of a composite sash on which the shoji of FIG. 1 is built, and FIG. FIG.

In FIG. 1, h denotes an upper frame, and a metal frame 1
0 and a resin frame 20 that covers a portion of the metal frame exposed on the indoor side. The metal frame 10 is formed of a shape material such as an aluminum alloy and has excellent weather resistance and mechanical strength. The resin frame 20 is formed of vinyl chloride, acrylic, or the like, and is excellent in heat insulation and design.

The metal frame 10 has a cylindrical portion 11 for providing strength at an intermediate portion in a height direction, extends upward from an outdoor side wall of the cylindrical portion, and fits an upper rail (not shown) of a window frame. Upper wall 12 constituting an outdoor side wall of rail fitting groove 30 for
It has a lower wall 13 extending downward and constituting an outdoor side wall of a glass fitting groove 40 for fitting an upper end of a shoji glass 50, and an upper rail on the upper end of the upper wall 12. There is formed a dovetail groove 14 for attaching an airtight material (not shown) which is brought into press contact with the groove. Also, the cylindrical portion 11 of the metal frame 10
In the web 15 on the rail fitting groove side which is the upper wall of the metal frame 10, the metal frame 10 is screwed through the metal frame of a vertical frame (not shown) of the sliding door and the metal frame of the combination frame. A screw hole 16 for screwing a screw penetrating from the outside of the door bottom side is formed.

On the indoor side surface of the upper wall 12, a protruding edge 17 protruding in the indoor direction near the web 15 is provided.
Is formed, and a fitting groove 18 that opens in the indoor direction is formed between the protruding edge and the web 15. Further, a fitting groove 110 that opens downward is provided at the indoor end of the web 19 on the glass fitting groove side, which is the lower surface wall of the cylindrical portion 11.

The resin frame 20 has a joining edge 21 extending in the outdoor direction at a middle portion in the height direction, and an upper wall 22 extending upward from the joining edge and constituting an indoor side wall of the rail fitting groove 30.
And a lower wall 23 extending downward from the coupling edge 21 and constituting an indoor side wall of the glass fitting groove 40. In addition, a dovetail groove 24 for attaching an airtight material (not shown) to be pressed against the upper rail is formed at the upper end of the upper wall 22. Further, a coupling edge 25 for fitting into the fitting groove 110 of the metal frame is provided at a middle portion in the height direction of the outdoor side surface of the lower wall 23.

In order to join the two frames 10, 20,
The following two methods are possible. One of them is both frames 10,
20 are placed in parallel, first, the tip of the upper joint edge 21 of the resin frame 20 is pushed into the upper fitting groove 18 of the metal frame 10, and at the moment when the resin frame is pushed down by using its elasticity, Connect the lower joining edge 25 of the resin frame to the lower fitting groove 1 of the metal frame.
10 is fitted. When the pressing force against the resin frame is released, the lower connecting edge is slightly returned upward by the elastic restoring force, so that the connecting edge 25 is tightly fitted and fixed in the fitting groove 110. Another method of joining is that the upper and lower joining edges 21 and 25 of the resin frame are fitted on the upper and lower sides of the metal frame with the opposite ends in the longitudinal direction of the two frames 10 and 20 on substantially a straight line facing each other. The mating grooves are fitted in the grooves 18 and 110, and both frames are relatively moved in opposite directions to each other so that each connecting edge is fitted in each fitting groove.
Fix it.

After the two frames are connected by fitting as described above, the protruding edges 17 of the metal frame 10 are caulked at a plurality of locations in the longitudinal direction thereof with a caulking machine (see FIG. 1).
a), the upper coupling edge 21 is strongly clamped between the projection 17 and the web 15; In this case, it is important that the caulking speed and the caulking strength by the caulking machine are such that the bonding edge 21 made of resin is not broken.

The projecting edge on the outdoor side forming the lower fitting groove 110 may be swaged at a position spaced apart in the longitudinal direction. In the present specification, the term “caulking” means deforming the protruding edge of the metal frame by physical force, and does not matter what means.

According to the above-described embodiment, since the protruding edge is simply pressed and deformed at an arbitrary position, compared with the case where the protruding edge is fixed with a screw or the like, there are no parts, holes at predetermined positions, screwing work of the screw, and the like. It is no longer necessary and costs are significantly reduced.
Then, since the connection is made by caulking, the integrated value in the longitudinal direction of the difference between the thermal expansion and contraction of the resin frame and the metal frame is absorbed in the caulked portion. Therefore, the problem of destruction of the fixing portion due to screws or the like is eliminated.

FIGS. 3 and 4 show an example of a composite sash on which the above-mentioned heat insulating sash is built. In FIG. 3, Hm is a metal frame formed of a metal having excellent weather resistance and mechanical strength, for example, aluminum or the like, and constituting a portion exposed to the outdoor side of the upper frame H of the window frame. Has mounting edges 1 and 2 for fixing the upper and lower sides to the building frame,
The outer rail ro, which guides the upper frame h of the shoji screen Do, has a hanging edge 3 which constitutes an outdoor side portion. Hp is a resin frame which is formed of a resin such as vinyl chloride or acrylic and has excellent heat insulation and design properties, and covers a portion of the metal frame Hm exposed to the indoor side. In the position where the outer rail ro is not formed, a hollow portion 4 is provided to form a double wall structure, and the inner rail Ro has the same strength as the outer rail ro in order to obtain as large a strength as possible within the restricted thickness range. Except for having a hollow inner rail ri having a cross-sectional shape,
The drooping edge 5 and the drooping edge 6 at the end on the indoor side of the indoor side portion o are formed to have a single thickness so that the expected width of the upper frame H is made as small as possible. The outer rail ro of the upper frame H has the same cross-sectional shape as the inner rail ri between the hanging edge 3 of the metal frame Hm and the hanging edge 5 of the resin frame Hp.

Sm is a metal frame that constitutes a portion of the lower frame S exposed to the outside, and has mounting edges 7 and 8 for fixing the lower frame to the building frame at two locations above and below. Shoji D
It has inner and outer rails ri and ro for guiding the lower frame s of i and Do. Since the lower frame S supports the load of the window frame itself and the entire load of the shoji, the highest strength is required among the window frames. Therefore, the metal frame Sm has substantially the same shape as the metal frame of the conventional lower frame. And has an inverted L-shaped rain return wall 9 which is locked to a window sill or a table board at the indoor side end. A groove 10 between the rain return wall 9 and the inner rail ri and a resin frame Sp that covers the upper surface of the rain return wall 9 of the metal frame Sm are fitted and mounted in the groove 10.

Jm is a metal frame that constitutes a portion of the left and right vertical frames J1 and J2 exposed to the outside of the window frame, and has a required strength. The resin frame Jp is fitted to the inner surface corresponding to the inner shroud Di of the metal frame Jm at two locations inside and outside, and the screw 11 at the portion where the metal frame Jm and the resin frame Jp overlap each other is formed. They are connected by fastening. Since the vertical resin frame Jp does not have a hollow portion and has a single wall structure, the vertical frames J1 and J
2 is reduced to fit the upper frame H and the lower frame S.

Next, the upper frame h and the lower frame s of the sliding sliding doors Di, Do built on the window frame F are metal frames hm, sm and the exposed portions of the metal frames on the indoor side, respectively. It consists of covering resin frames hp and sp. The metal frames hm and sm are formed as thin as before, and the resin frames hp and sp do not have a hollow portion on the indoor side. It is formed as thin as possible. The vertical frame j1 on the door end side (door stop side) may receive a strong collision force from the vertical frames J1 and J2 of the window frame via the pulling member b when opening and closing the shoji, or generate strong wind pressure in the closed state. In order to withstand the impact force and wind pressure, the resin frame jp1 of the vertical frame j1 on the side of the door should have the required strength.
Has a hollow portion td having a minimum thickness.

[0023]

As described above, according to the present invention, the resin frame and the metal frame are connected by caulking at a plurality of longitudinal positions of the protruding edge to which the connecting edge is fitted.
The coupling can be easily performed, and the coupling strength is remarkably enhanced. In addition, the problem based on the difference in the expansion and contraction rate between the resin frame and the metal frame is skillfully solved.
