TECHNICAL FIELD OF THE INVENTION
The present invention relates to a lower frame insulation structure of a shoji having a structure in which a hanging piece is hung from a lower frame of a sliding door such as a sliding shoji, and the hanging piece is fitted into a slide groove formed on a lower frame upper surface substantially flat lower frame upper surface. .
[0002]
[Prior art]
In sliding doors and sliding windows consisting of outer sliding doors and inner sliding doors, the lower frame consisting of a conventional ridged rail for outer sliding doors and a ridged rail for inner sliding doors has the same There is known a heat insulating sash structure in which a heat insulating member is inserted and connected between rails for a shoji (see FIG. 3 of JP-A-2000-337024).
However, in order to form the upper surface of the lower frame almost flat, for example, as shown in FIG. 7, the hanging pieces are respectively suspended from the lower frame of the outer sash and the lower frame of the inner sash. When a structure in which a sliding groove for a sliding door is formed is used, the upper surface of the lower frame is located at a portion A outside the sliding door from the outer sliding door, at a portion B between the sliding groove between the sliding outer door and the sliding groove inside the inner sliding door, and at the inner side of the sliding groove from the sliding inner sliding door. Part C is divided into three parts.
[0003]
In the case where the lower frame has an insulating structure, as shown in FIG. 7 (a), even if an attempt is made to cut off the heat conduction by the heat insulating member at the inner sliding door sliding groove, the lower sliding door and the inner sliding door are closed when the outer sliding door and the inner sliding door are closed. The portion B on the upper surface of the frame is exposed inside the room, and if this portion is not blocked, heat conduction is large, which may cause dew condensation and the like.
The lower frame upper surface sandwiched between the outer sliding door lower frame hanging piece and the inner sliding door lower frame hanging strip guides the sliding of the sliding door and serves as a rail for the outer sliding door. There is a problem in that forming with resin or the like is weak in strength.
Furthermore, since a person walks or a wheelchair travels on the upper surface of the lower frame, there is also a problem that the resin or the like is easily damaged.
[0004]
In addition, as shown in FIG. 7B, in addition to FIG. 7A, there is a type in which a heat insulating member such as a resin material is inserted and connected also to the sliding slide groove portion of the sliding door. Because of its weakness, the load capacity of the lower frame for the entrance is likely to be insufficient, and it is difficult to secure the strength of the externally attached portion, particularly in a semi-external type sash structure.

[Problems to be solved by the invention]
The present invention has been made in view of the technical problems of the prior art described above, and has a hanging piece that is hung down from a shoji lower frame and is fitted into a slide groove on the upper surface of the lower frame, in which the strength and scratch resistance of the lower frame are reduced. An object of the present invention is to provide a sash structure having a substantially flat upper surface of a lower frame, which is excellent in heat insulation while ensuring the same.
[0007]
[Means for Solving the Problems]
According to the invention of claim 1, the upper surface of the lower frame of the sash formed of the sliding shoji provided in the outdoor opening of the building is formed substantially flat, and the hanging pieces are hung from the lower frame of the outer shoji and the inner shoji. Then, the above-mentioned hanging pieces are fitted into the thin strip-shaped outer sash sliding groove and the inner sash sliding groove provided on the lower frame upper surface, respectively, and the lower frame upper surface located between the outer sash sliding groove and the inner sash sliding groove is removed. An upper member made of metal was formed, and this upper member was attached to the lower frame base member via a heat insulating member.
[0008]
As described above, by providing the heat insulating member between the upper member of the lower frame and the base member of the lower frame disposed between the outer sash sliding groove and the inner sash sliding groove, heat insulation between the sliding grooves of the lower frame is improved. In addition to this, the strength for guiding the sliding of the shoji is ensured, and the lower frame upper member is also prevented from being damaged.
It is to be noted that the purpose of insulating the upper surface member disposed between the outer sash slide groove and the inner sash slide groove is to originally insulate a portion exposed to the indoor side when the sash is closed. .
Therefore, the upper surface member does not necessarily have to be insulated over the entire length, and it is sufficient that at least a portion located on the indoor side is insulated.
[0009]
According to the invention of claim 2, the upper surface of the lower frame of the sash formed of the sliding sash provided in the outdoor opening of the building is formed substantially flat, and the hanging pieces are hung from the lower frame of the outer sash and the inner sash. Then, the above-mentioned hanging pieces are fitted into the thin strip-shaped outer sash sliding groove and the inner sash sliding groove provided on the lower frame upper surface, respectively, and the lower frame upper surface located between the outer sash sliding groove and the inner sash sliding groove is removed. An upper surface member made of a low heat conductive material such as resin was formed, and a metal protective cover member was attached to the upper surface member.
[0010]
In this manner, the lower frame upper surface member is formed of a low thermal conductive material such as a resin to secure heat insulation between the slide grooves of the lower frame, and the upper surface thereof is formed of, for example, a protective cover member made of a SUS material. The cover prevents the surface from being damaged.
Here, it is preferable that the cross-sectional shape of the protective cover member is formed into a substantially L-shape, a substantially U-shape, or the like, and attached from the upper surface of the upper member to the side.
[0011]
According to the invention of claim 3, the upper surface of the lower frame of the sash formed of the sliding shoji provided in the outdoor opening of the building is formed substantially flat, and the hanging pieces are hung from the lower frame of the outer shoji and the inner shoji. In the lower frame structure in which the above-mentioned hanging pieces are respectively fitted in thin strip-shaped outer sash sliding grooves and inner sash sliding grooves provided on the upper surface of the lower frame, the outdoor member is formed with the lower frame bordering the inner sash sliding groove. And the indoor-side member, and the outdoor-side member and the indoor-side member were connected to each other at the upper part of the frame mounting surface by using a heat insulating member.
[0012]
As described above, when the connecting portion using the heat insulating member of the lower frame is provided on the upper portion of the skeleton mounting surface, the load of the sash is not directly applied to the heat insulating member portion, but is applied to the skeleton mounting surface, and the stability of the heat insulating member portion is stabilized. It becomes easy to secure.
[0013]
According to a fourth aspect of the invention, the configuration of the third aspect of the invention is added to the configuration of the first or second aspect of the invention to prevent the formation of dew on the indoor side of the lower frame.
[0014]
In this way, by performing heat insulation while securing the strength of the lower frame exposed to the indoor side, it is possible to prevent the occurrence of dew condensation on the indoor side.
[0015]
According to the fifth aspect of the present invention, the protective cover members are respectively attached to the upper surfaces of the lower frames divided by the outer sash sliding groove and the inner sash sliding groove.
[0016]
Thus, for example, the lower frame base member and the upper surface member are made of an aluminum alloy extruded material, so that the productivity is high. In addition, by covering the lower frame upper surface with a hardly scratchable protective cover member such as a SUS material, the overall design and the scratch resistance are improved. Stickiness is improved.
Further, the number of types can be easily increased so that the color and pattern of the upper surface of the lower frame can be selected according to the interior.
[0017]
According to a sixth aspect of the present invention, in the first aspect of the invention, the heat insulating member sandwiched between the metal upper member and the lower frame base member is divided into an outdoor side portion and a lower portion of the upper member. The heat insulating member on the outdoor side was made of a soft resin or rubber material.
[0018]
Accordingly, the gap between the side of the upper surface member and the lower frame base member is sealed by attaching a heat insulating member made of a soft resin or a rubber material so as to be in close contact therewith, thereby preventing water or dust from entering.
That is, since a large load is applied to the lower portion of the upper member when walking or the like, the heat can be insulated with a hard resin such as hard vinyl chloride resin, and the outdoor side portion of the upper member has better sealing performance than load resistance. As required, an elastic material can be used.
Further, when the heat insulating member in the lower part is divided in the longitudinal direction, a drainage channel of the inner sliding door slide groove can be formed by using the division.
[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a longitudinal sectional view of a sash structure according to the present invention, and FIG. 2 is a transverse sectional view thereof.
FIG. 3 is an enlarged view of the lower frame portion.
The lower frame 10, the upper frame 20, and the right vertical frame 30 and the left vertical frame 40 from the room to the outside form a substantially rectangular frame body at the opening of the building, and the openings are sequentially formed at the openings from the outside. , A screen door 70, an outer sash 50, and an inner sash 60 are slidably opened and closed.
The screen door is attached as needed.
Further, in the case of the sliding sash shown in the figure, there are two sliding doors, an outer sliding door and an inner sliding door, but the present invention is also applied to a sliding door having four sliding doors or the like.
[0020]
