Abstract

<P>PROBLEM TO BE SOLVED: To eliminate the inconvenience that a lack of transparency and troublesome attachment/detachment are caused though air packing is generally attached to a glass door so as to reduce the amount of heat discharge from a room using a heater. <P>SOLUTION: An energy-saving door using a transparent plastic plate or plastic film is installed in place of a wire screen, so that the amount of the heat discharge from the glass door can be reduced in such a manner that good visibility and easy attachment/detachment can be brought about. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

According to the present invention, an energy saving door made of a transparent plastic is attached to the outside of a glass door, thereby reducing the amount of heat released from the room and preventing condensation on the glass door.

In order to reduce the heating cost at home, it is common practice to attach an air packing to the glass door to reduce the amount of heat released from the glass door and prevent condensation.

When the air packing is affixed to the glass door, there is a problem that the line of sight is deteriorated and further, it takes time to mount and remove the air packing.

In order to solve this problem, the invention according to claim 1 is a heat-insulating air layer in which an energy-saving door in which a transparent plastic film is attached to a transparent plastic plate such as acrylic or a lightweight frame such as aluminum is installed outside the glass door. The amount of heat released from the room is reduced and condensation is prevented.

Further, the invention of claim 2 can eliminate the need for an appliance for mounting the energy-saving door by attaching the energy-saving door of claim 1 to the screen door mounting bracket instead of the screen door that has been removed out of season. It becomes.

Further, the invention of claim 3 requires ventilation when using an oil stove or gas stove, and may require entry and exit, and an opening / closing window is provided to save the trouble of removing the energy-saving door each time. This allows ventilation and human access.

According to the present invention, it is possible to reduce the heating cost by installing a heat insulating door that has good visibility and is light and easy to remove.

In addition, since the screen door mounting bracket after being removed is used as it is, it is possible to eliminate costs other than the energy saving door.

An embodiment relating to an energy-saving door of the present invention will be described.
This embodiment is described for better understanding of the gist of the invention, and does not limit the present invention unless otherwise specified.

FIG. 1 is a front view and a side view of an energy saving door in which a transparent acrylic film 2 is pasted on both sides of an aluminum frame 1. A groove for attaching the acrylic film 2 is cut in the aluminum frame 1, and the acrylic film 2 is sandwiched between the rubber straps 3 for fixing the sheet. On the upper part of the aluminum frame 1, a spring-loaded door wheel 4 is attached for easy installation. A rubber packing 5 for blocking outside air is attached to the outer periphery of the aluminum frame.

When reducing heat dissipation from a glass door by air packing, the transparency is lost, and there is a disadvantage that it is difficult to apply to a glass door in a room with a view of the garden such as a tatami room. Any glass door can be installed in any room, thus saving energy.

It is explanatory drawing which shows the front view and side view of a heat insulation door which use a transparent acrylic film.
