Description

[Detailed Description of the Invention] The present invention relates to a double window for a bathroom, and particularly to the structure of a lower frame for an inner sash frame.

Generally, the bathroom is a hot and humid place where condensation tends to form on the surface of the sash frame and shoji frame.
In particular, when a double sash with an inner sash frame and an outer sash frame connected to each other is used for a bathroom window in order to obtain a heat insulating effect, a large amount of condensed water adheres to the glass of the inner sash frame and the surface of the shoji frame. Conventionally, this condensed water was drained to the outer sash frame, but in severe cold weather,
The problem is that the condensed water freezes, making it impossible to open and close the shoji.

Therefore, the present invention aims to solve these problems and allow the shoji stile to open and close smoothly even when the condensed water flows down.In particular, the structure of the lower frame for the inner sash frame has been devised. , dew condensation water can be smoothly and reliably discharged not to the outside but to the inside of the room, that is, into the bathroom.

That is, in the present invention, the sliding surface of the lower frame that constitutes the inner sash frame of the double sash is sloped downward toward the indoor side, and the lower frame is sloped downward toward the indoor side and protrudes from the indoor side surface of the house wall. A series of smooth protruding walls,
A rising part is provided at the indoor end of the projecting wall, a drainage hole is provided near the outdoor side of the rising part and at a distance from the wall of the house, and a cover is attached to both ends of the projecting wall. It is characterized by:

Hereinafter, the present invention will be explained based on the illustrated embodiment. The lower frame 1 forming the inner sash frame A has two rails 2 for running the shoji on the running surface of the shoji.
3 protrudingly provided, the lower frame 1 has a downward fitting groove 4 at its outdoor end, and a plate-like smooth protruding wall 5 at its indoor end, which is integrally extruded. However, the running surface A of the shoji is formed as a downward slope from the outdoor end to the indoor end,
The protruding wall 5 has a dimension that protrudes from the indoor side surface B of the house wall 6, and has a rising part C projecting upward at the indoor end, and an L-shaped hanging piece 7 hanging from the rising part C. There is. Furthermore, a drain hole 22 is formed in the protruding wall 5 on the outdoor side of the above-mentioned rising portion C and at a distance toward the indoor side from the indoor side surface B of the house wall body 6.

This protruding wall 5 is cut to the same length as the entire length of the inner sash lower frame 1, and a cover 21 is fitted to the cut end in consideration of safety in the bathroom.

A synthetic resin heat insulating material 8 is attached to the fitting groove 4 at the outdoor end, and the heat insulating material 8 is attached to the window sill in the lower frame 9 of the outer sash frame B fixed to the outdoor side of the house wall 6. The lower frame 9 for the outer sash frame and the lower frame 1 for the inner sash frame are stacked on top of the stopper 10, and at this overlapping part, the lower frame 9 for the outer sash frame and the lower frame 1 for the inner sash frame,
A continuous lower frame for the double sash is formed by integrally connecting them with screws, etc., and the continuous lower frame is made of synthetic resin heat insulating material 8. It has the effect of blocking heat conduction,
This prevents condensation on the indoor side.

Further, the continuous upper frame 11 for the double sash frame is also formed with the same structure, but the left and right continuous vertical frames 12 and 13 are formed in advance by forming a vertical frame 14 for the outer sash frame and a vertical frame 15 for the inner sash frame.
are integrally extruded, a heat insulating material 17 is injected and filled into a groove 16 formed at a location where a heat insulating part 2 is to be formed, and after hardening, a connecting wall 18 connecting both vertical frames 14 and 15 is cut out. In this way, the integrity of both the inner and outer vertical frames 14, 15 is cut off, and heat conduction to the outside and inside of the room is cut off.

Although the double sash shown in the figure has such a heat insulating structure, it is difficult for condensed water to adhere to the surfaces of the shoji 19 and 20 attached to the inner sash frame A, especially in a bathroom in a hot and humid environment. Although it is unavoidable, the condensed water that has fallen down the surface of the shoji 19, 20 will flow toward the indoor side and drain into the drainage hole because the shoji running surface A and the protruding wall 5 are inclined toward the indoor side. 22 and definitely flows into the bathroom.

As described above, since the condensed water quickly flows down into the bathroom, there is no condensed water falling on the lower frame 9 for the outer sash frame, and therefore the shoji 2 of the outer sash frame B
3 and 24 will not freeze and become impossible to open and close.
This allows for smooth opening and closing.

Furthermore, the protruding wall 5 can be used as a storage place for small items necessary for the bathroom, but since the protruding wall 5 has a rising part C protruding from the indoor end, the rising part C does not serve as a stopper. , the above-mentioned small items can be stably placed on the protruding wall 5 without slipping down to the indoor side.

Furthermore, although the protruding wall 5 protrudes from the indoor side surface of the house wall 6, the covers 21 are attached to both ends of the protruding wall 5, so that hands, feet, etc. There is no fear of damage, and condensed water, etc. can be prevented from flowing down from both ends of the protruding wall 5, and the condensed water, etc. can be reliably guided from the drain hole 22 into the bathroom.
