Description

[Detailed explanation of the invention] This invention is installed under the seat of a chair to prevent the knees, back of the calves, ankles, and soles of the feet from getting cold when a person is sitting on the chair during winter. Regarding chair heaters used to prevent heat rays, the heater body is equipped with a radiation/discharge port for heat rays or hot air currents on the front surface, and an appropriate space is provided between the heater body and the top surface of the main body. A heat shielding plate that covers a wide area of the upper side is attached, and the front part of the heat shielding plate has a structure in which a plate material with a corrugated cross section and easy to bend is attached to a bendable beam body, and the front part is bent downward. A heater for a chair, characterized in that it is formed in the shape of an eave that is curved or bent toward the front, and can be installed under the seat of the chair with the radiation/emission port directed toward the front of the seat of the chair. .

If you try to keep the heating in a room to a minimum in order to save energy in the winter, the air in the room at a lower location will inevitably have a lower temperature than the air at a higher location in the room. Due to the lack of sufficient heat-retaining clothing, when a person attempts to sit on a chair for a long time, the knees, back of the calves, and ankles become cold and can cause pain. There are quite a few. For this reason, heating equipment for people sitting on a chair has been devised that allows the lower body to be completely stored inside a bag-like heater equipped with a heater, but this restricts the freedom of the lower body. It is unsightly and difficult to use in offices. The present invention can be used unsightly on office chairs and can be easily attached as an accessory to the chair, and while the backs of the knees will not be overheated, the calves and ankles can be heated as desired. To provide a simple chair heater devised to provide warmth.

The present invention will be described below with reference to drawings showing embodiments thereof.

As shown in FIGS. 1 and 2, the electric heater 7 is equipped with an electric heater 7 and a reflector 8 inside.
While reflecting the heat rays or hot air flow from the reflector plate 8, the heat rays or hot air flow are radiated/released to the outside via the heat ray or hot air flow radiation/discharge port 2 provided with the protective metal fence 9 provided on the front part 1. A heat shielding plate 5 is attached to the main body 3 of the heater in such a manner as to broadly cover the upper side of the radiation/discharge port 2 while providing a space 4 of an appropriate width between the top surface of the main body 3 and the upper surface of the main body 3. As shown in FIG. 6, the front part 6 of the heat shielding plate 5 can be bent or bent to an appropriate inclination or angle as needed by using an appropriate number of thick copper wires or flexible tubes. By attaching a plate material 22, which has a corrugated cross-section and is easy to bend, such as a corrugated iron plate, to the beam body 21 of the beam body 21, the degree of curvature of the front part 6 can be easily adjusted at any time. The front part 6 of the heat shielding plate 5 is formed into an eave shape that gently curves downward as appropriate, and the main body is placed under the seat of the chair. 3. Radiation of heat rays or hot air currents
This heater for a chair can be installed with a discharge port 2 directed toward the front of the chair seat.

In addition, numeral 10 in the drawing indicates a power supply wire, and the method of attaching the heat shield plate 5 to the heater main body 3 is as follows.
A shielding plate support 11 fixed to the lower surface of the heat shielding plate is fixed to the side surface of the main body 3 with fixing bolts 12, and the support 11 is provided with a number of bolt holes 13 as shown in FIG. In addition to being able to adjust the width of the space 4 between the heat shield plate 5 and the upper surface of the main body 3 as indicated by the dashed-dot line, the angle at which the main body 3 is fixed to the support 11 is also indicated by the dashed-double line in FIG. It can be adjusted as appropriate. Furthermore, what is shown by the two-dot chain line in FIG. 1 is a reflective door 20 that is attached to the front part of both sides of the main body 3 so as to be rotatable in the direction of the arrow shown in the figure, if necessary. It is installed as appropriate to prevent the flow from escaping to the side.

As shown in FIGS. 3 and 4, such a chair heater can be installed on the seat 15 of an appropriate chair 14.
The heat rays or hot air currents are directed to the front of the seat 15 through a suitable mounting device 18 below, a mounting belt 16 as shown by the dashed-dotted line in FIG. If installed in a tilted manner, when a person sits on the seat, the heat rays or hot air currents will hit the person's calves and ankles just right, making it possible to comfortably heat those areas. While the heating temperature of the calves and ankles can be freely changed and adjusted by moving the position back and forth as appropriate, the area around the knees, which cannot be easily moved once you are seated, A heat shielding plate 5 that exists apart from a space 4 of an appropriate width from the top surface of the heater body 3 and a downwardly curved or curved eave-shaped front part 6 of the heater body 3 prevent heat rays radiated from the front surface of the heater body 5 or Since it successfully blocks the flow of hot air from directly hitting or touching the area around the knee, the knee area is not overheated at all, and is warmed gently and indirectly using only the hot air from the surrounding area. Therefore, in the winter, the area below the knees gets cold, making it difficult to work while sitting on a chair, or conversely, the situation where the heater burns or burns the back of the knees can be avoided very conveniently. be.

Further, the heat shielding plate 5, which is present across the space 4 from the heater body, catches easily twisted items such as rags that fall from below the seat 15 of the chair 14, and prevents them from touching the heater body and igniting. It also helps prevent it from happening.

What is indicated by a dashed line in FIG. 1 is a non-twisted shielding plate or woven fabric 19 such as plasterboard, asbestos board, or glass fiber cloth attached to the upper surface of the front part 6 of the heat shielding plate 5. This is to prevent the risk of burning even if clothing that covers the area gets attached.

Furthermore, FIG. 5 shows that there is a case where the heater of the present invention is installed and fixed under the seat while the part of the heat shield plate 5 excluding the front part is used as the bottom plate of the seat 15 of the chair. It shows.

In the above-mentioned embodiment, the heat source of the heater body 3 was an electric heater, but it goes without saying that this heat source can be replaced with an infrared lamp, a small kerosene stove, a heater using exhaust hot air from an internally twisted engine, or water vapor. .
