JPS603265Y2 - Bottom frame of inner satsushi for bathroom - Google Patents

Description

[Detailed explanation of the invention] This invention is a double sash used in a bathroom.The inner sash of the double sash used in the bathroom has a lower frame shaped like a cross section, and has a downward slope toward the outside of the room. This relates to a lower frame of an inner sash for a bathroom, which is intended to allow water droplets generated to flow down naturally.

Conventionally, double sash with high sound insulation and heat insulation performance has been used for windows in buildings, and double sash is often used for bathroom windows to insulate them from the outside temperature. Due to the inner sway, water droplets adhering to both sides of the glass plate, especially the inner window surface, flow down to the lower frame, but if the flow from the lower frame is poor, it is undesirable in winter as it may cause freezing at night.

In the conventional double sash for bathrooms, the lower frame of the inner sash is such that the entire lower frame member is inclined toward the inside of the bathroom.
Because the gradient in which water droplets flow is maintained, the flow of water droplets that occur on the intermediate air layer side of the double sash (outside the shoji of the inner window) is poor, which poses a problem in terms of drainage on the bottom frame. Ta.

However, in this invention, the lower frame of the inner sash of the double bathroom sash is made into a cross-sectional shape, and a rail for the outer shoji is installed near the top of the lower frame to create a watershed, so that water droplets that occur on the inner window can be easily removed. The ones inside the bathroom flow down into the bathroom through the bottom frame of the outside shoji rail (inside the bathroom), and the ones on the middle air layer flow down the bottom frame of the outside shoji rail (outdoor side). Since the water flows down through the lower frame of the outer window sash to the outside, it has excellent drainage, eliminates the cause of freezing, and solves the problems of the conventional method.

That is, to explain an example of this invention, it is a cross section of the inner window sash of a double sash for a bathroom! A rail 3 for the outer shoji 2 of the inner window is protruded from the top of the rib-shaped lower frame 1, and a rail 3a for the inner shoji 2a of the inner window is protruded from the inclined part 1a inside the rail 3 (inside the bathroom). The outside (outdoor side) of the rail 3 is used as the sloped part 1b to constitute the lower frame of the inner sash for the bathroom, and the outside (outdoor side) of the inner sash is adjacent to a normal outside window sash. , a protrusion 1c protruding from the inner end 4a of the lower frame 4 of the outer window sash and the lower part of the inclined part 1b of the lower frame 1 of the inner window sash.
These are fixedly connected with screws 6 through a backing 5.

In the figure, 7 is a rail for the outer shoji 8 of the outer window, and 7a is a rail for the inner shoji 8a of the outer window.

The drainage effect when using the lower frame of the bathroom sash according to this invention is that as for the outer window, rainwater, etc., flows down the lower frame 4 of the outer window sash along the slope toward the outside, preventing rainwater from entering. In addition, the rail 3 for the outer shoji of the lower frame 1 of the inner sash can act as a watershed, so the outer shoji 2 of the inner sash
Water droplets generated on the inside (inside the bathroom) A and the inside and outside of the internal shoji 2a flow down on the slope 1a as shown by the arrow 9, and enter the bathroom through the bent part 11 protruding from the inside end of the lower frame. Water droplets that are drained and generated on the outside (outdoor side) B of the inner outer shoji 2 flow down on the inclined part 1b as shown by the arrow 10, and go to the outside through the bent part 12 protruding from the outer end of the lower frame. It flows down on the bottom frame of the window sash and drains water.

That is, according to this invention, the outer shoji rail of the lower frame of the inner sash of the double sash for bathrooms is used as a watershed, so water droplets generated on the inner window surface etc. can be drained well, and the structure with a curved cross section prevents rainwater etc. However, the drainage of rainwater, etc. that has entered against one's will is as good as the drainage of water droplets, and there are various effects such as easy drainage during cleaning.
