Abstract

PROBLEM TO BE SOLVED: To prevent a stay of dew condensation water or the like by respectively arranging mutually opposing joing grooves on the outdoor end of an indoor side section and the indoor end of an outdoor side section by protrusively arranging a pair of upper and lower inclined part pieces, and joining the indoor and outdoor sections to each other by fitting a heat insulating joining material to the joining grooves. SOLUTION: A lower frame A is formed by joining an indoor side section 1 and an outdoor side section 2 to each other through a heat insulating joining material 3. A joining groove 7 in which an upper inclined part piece 5 and a lower inclined part piece 6 are protrusively arranged downward in a parallel shape, is arranged just under a guide rail 4 in the section 1. A joining groove 12 in which an upper inclined part piece 10 and a lower inclined part piece 11 are protrusively arranged upward in a parallel shape, is arranged on the indoor end of the section 2. The joining material 3 is interposed between the section 1 and the section 2, and the sections 1 and 2 are engaged with each other. In this way, a joining part upper surface joined by using the indoor and outdoor sections inevitably becomes an inclined shape. Therefore, the lower frame of a heat insulating sash by which water such as dew condensation water does not infiltrate into a room by staying in a boundary part between the joining material and the sections and which is excellent in water treatment, can be provided.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower frame of an insulating sash having an extruded aluminum profile as a main member.

[0002]

2. Description of the Related Art A structure in which an indoor side member and an outdoor side member are separated and these two members are connected by a heat insulating binder is known, for example, as described in JP-A-8-13531. is there.

In this conventional example, specifically, a pair of upper and lower horizontal pieces are provided at an outdoor end of an indoor side profile and an indoor end of an outdoor side profile, respectively, to form connecting grooves facing each other. A heat insulating connecting material is fitted into the connecting groove to connect the indoor and outdoor profiles to each other.

[0004]

In the prior art described in the above-mentioned publication, the two members are joined by fitting the joining members into joining grooves formed by horizontal pieces provided in the indoor and outdoor profiles. Therefore, when the upper surface of the connecting portion is horizontal, the dew condensation water and rain water easily accumulate, and there is a possibility that the dew condensation water and the like may enter the room through the boundary between the bonding material and the two shaped members.

The present invention pays attention to such a conventional example, and arranges a connecting groove for fitting a bonding material in an inclined direction to prevent dew water or the like from accumulating on an upper surface of a connecting portion, and to reduce the size of the connecting material. Water is prevented from entering the indoor direction through the boundary with the profile.

[0006]

A pair of upper and lower inclined parts are provided at the outdoor end of the indoor side profile and the indoor end of the outdoor side profile, respectively, to form connecting grooves facing each other. A heat-insulating binder is fitted to the inside and the indoor and outdoor profiles are connected to each other.

[0007]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of a lower frame of a heat insulating sash according to the present invention. A lower frame A of the embodiment comprises a window frame of the heat insulating sash by an upper frame and right and left rigid frames. An inner profile 1 and an outdoor profile 2 are connected to each other via a heat insulating binder 3.

[0008] The indoor side profile 1 is a guide rail 4 for the inner shoji 8.
At the outdoor end, and an upper inclined piece 5 just below the guide rail 4.
And the lower inclined piece 6 is provided so as to protrude downward in a parallel manner to provide a coupling groove 7 having an opening on the outdoor surface side.

The outdoor side section 2 has a guide rail 9 for the outer sash 8 'at an intermediate portion in the expected direction, and has an upper inclined piece 10 and a lower inclined piece 11 at the indoor end in a parallel upward direction. A connecting groove 12 is provided in the indoor surface side opening facing the connecting groove 7 provided in the indoor side shape member 1 so as to protrude.

The upper inclined piece 5, which forms the coupling grooves 7, 12,
10 and the lower inclined part pieces 6 and 11 on opposite sides (the coupling grooves 7 and 1).
2), a ridge having a triangular cross section is provided as shown in the figure, and the ridge engages with the groove 13 formed in the bonding material 3 so that the ridge does not come off through the openings of the engaging grooves 7 and 12. It is.

The bonding material 3 is made of a hard synthetic resin (a nylon resin in the embodiment), and is composed of a rod having the groove 13 along the longitudinal direction. The protrusion is engaged with the groove 13. In this way, the indoor and outdoor sections 1 and 2 are engaged with each other, interposed between the indoor section section 1 and the outdoor section section 2.

FIG. 15 shows a cover made of hard rubber.
The cover 15 is arranged at a portion located outside the inner sash 8 when the sash is closed to prevent the binder 3 from irradiating with sunlight and changing over time. It is locked in a locking groove 16 provided directly below the rail 4, and an outdoor end is locked in a locking groove 17 provided in a base of the guide rail 9 of the outdoor side member 2, and arranged as described above. is there.

As shown in FIG. 2, a plurality of connecting members 3 may be used. In this case, connecting grooves 7 and 12 corresponding to the respective connecting members are provided as shown in the drawing.

Further, a drain portion is formed by notching the end of the guide rail 9 of the outer sash 8 'on the rigid frame side, and the upper surface of the joining portion 3A of the two shaped members 1 and 2 by the joining material 3 is formed. Water such as dew on the side is discharged to the outside through the drainage section.

[0015]

The present invention has the configuration described above,
The upper surface of the joint part joined using the joining material of indoor and outdoor shapes,
Inevitably becomes inclined, at the boundary between the binder and the profile,
It is possible to provide a lower frame of a heat insulating sash which is excellent in water treatment so that water such as dew condensation water does not stay and enter a room.
