Description

[Detailed Description of the Invention] The present invention relates to a sash door with a ventilation opening.

Traditionally, satsushi doors used in general buildings completely cut off air between the indoor and outdoor sides, providing soundproofing and heat insulation effects, but these types of doors are used in closed rooms during the winter. When heating equipment is used, the air becomes unnecessarily dry or polluted, which not only has an adverse effect on health, but can also cause carbon monoxide poisoning.

In view of this problem, the present invention provides a receiving hole at the lower edge of the sash door, and a ventilation box is fitted into this receiving hole so that the indoor air is constantly ventilated with fresh air.

An embodiment of the present invention will now be described with reference to the drawings.

A in the figure is a ventilation box, and a semicircular ventilation hole 2 is provided on the front wall of the hollow main body 1 so that the lower edge is on the same plane as the inner bottom surface of the main body 1. A circular ventilation hole 3 is provided so that the edge is located above the inner bottom surface of the main body, and a flange plate 4 is edged on the peripheral edge of the front wall of the main body 1 on the same plane as the front wall.

It should be noted that the ventilation holes of the ventilation box A are arranged in different positions depending on whether the ventilation box A is installed from the outdoor side or the ventilation box A is installed from the indoor side.

That is, as shown in Figure 2 of the drawing, the ventilation box A attached to the sliding door frame 5 on the outdoor side, which will be described later, has a circular ventilation box on the front wall of the hollow main body 1 so that the lower edge is located above the inner bottom surface of the main body 1. A vent hole 3 is provided, and a semicircular ventilation hole 2 is provided on the rear wall surface so that the lower edge is on the same plane as the inner bottom surface of the main body 1, and a ventilation box A is attached to a sliding door frame 5 on the indoor side, which will be described later. As shown in Figure 3 of the drawing,
A circular ventilation hole 3 is formed on the rear wall of the hollow main body 1 so that its lower edge is located slightly above the inner bottom surface of the main body 1.
A semicircular ventilation hole 2 is provided on the front wall surface so that its lower edge is flush with the inner bottom surface of the main body 1.
5 is a sliding door frame that fits into the metal window frame B, and 6 is a receiving hole for one or more ventilation boxes A provided at the lower edge of the sliding door frame 5.

Reference numeral 7 designates a screw hole for fixing the flange plate 4, which is protruded from the periphery of the front wall of the main body A on the same plane as the front wall, to the lower edge of the sliding door frame 5 with screws.

Since the present invention is constructed as described above, the receiving hole 6 provided at the lower edge of the sliding door frame 5 that fits inside the metal window frame B has a ventilation box in which the collar plate 4 is located inside the sliding door frame. The flange plate 4 fits into the receiving hole 6 provided on the lower edge of the sliding door frame 5 which fits on the outside, and the ventilation box located on the outside of the sliding door frame 5 fits. Since there is no contact when opening and closing the ventilation box, there is no need to damage the sash door when installing the ventilation box.In addition, the ventilation hole facing outdoors is flush with the inner bottom surface of main body A, which is formed in a semicircular shape. The part facing indoors is formed in a circular shape and is placed above the inner bottom surface of main body A, so there is no risk of rainwater entering the room, and ventilation of indoor air is performed smoothly. It is highly effective as a satsushi door with ventilation holes.
