Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating device, and more particularly to a heating device for warming the legs of a human body.

The kotatsu has long been known as a device of this type, but with a kotatsu, you generally sit on the floor and insert your legs into the kotatsu to keep yourself warm. Therefore, staying in the same position for a long time causes physical pain,
The drawback is that it is not suitable for long-term use.

This drawback can be overcome by using a so-called hori-kotatsu, which has a downward step on the floor and allows the user to sit on the floor as if sitting on a chair.

However, with this horigotatsu, the heat source is placed at a fixed location, so the kotatsu itself cannot be moved to a desired location, which is inconvenient.

The purpose of the present invention is to provide a heating device for warming the legs of the human body that eliminates the drawbacks of conventional kotatsu. A seat is provided at a suitable location near the periphery of the frame, the seat is rotatable in a plane parallel to the floor and is at a height where the user can sit with his or her knees without being obstructed by the frame; The planar shape of is such that an appropriate number of chairs are arranged in a non-fixed manner, and a portion of the circular shape at the tip is notched enough to fit the knees of a seated user within the circular shape, and the chairs are placed in a predetermined usage position. In some cases, in order to substantially close the space existing between the upper surface of the frame and the floor, a suitable flexible heat leakage prevention member is suspended from the upper surface of the frame toward the floor so as to reach at least the seat of the chair. At the same time, the gap remaining between the heat leakage prevention member and the floor surface is such that an extremely narrow gap is provided on both sides of the chair to ensure rotation of the chair and prevent heat leakage. A closing member that is fixedly placed on the floor surface and whose side surface on the chair side is recessed in the shape of an arc groove following the rotational surface of the seat, and a space between these closing members that is in contact with each of the closing members or is extremely narrow. The closed space is almost closed by a closing plate placed with a gap therebetween, and an appropriate heat source is disposed within this nearly closed space, and the inside of the closed space is heated by the heat released from this heat source. It is located where it is configured.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The seat is set at a position where the user can sit down without being obstructed by the seat, and its planar shape is formed into a notched circular shape in which a portion of the circle at the distal end is cut out enough to fit the knees of the seated user within the circle. ing.

This notched circle corresponds to each of the recessed portions 6a, 6f, 6b,
6 g, 6 C, 6 h, 6 d.

The radius is slightly smaller than the radius forming the arc 6e.

And each chair 7a, 7b, 7C. 7d, each of the seat portions 10a, 10b, 10C, 10d (7) has a circumferential surface corresponding to the recessed portion 6a, 6f, 6b, 6g, 6C of each of the support stands 4a, 4b, 4C, 4d. ,6h,6d,6
It is placed on the floor surfaces F and L with an extremely narrow gap that allows it to rotate with e.

Each chair 7a, 7b, 7C, 7d has its own seat portion 10.
The state in which the notches a, 10b, 10c, and 10d are shown in solid lines in the figure and facing toward the frame 1 is the usage position.

Although each of the support stands 4a, 4b, 4C, and 4d and each of the chairs 7a, 7b, 7C, and 7d are movable with respect to the floor surfaces F and L, they must be made sufficiently so that they do not move due to a slight impact. It has weight.

Since the present embodiment is configured as described above, a person who wants to keep warm can operate the electric heater 14 and rotate the seat 10b of the desired chair, for example, the chair 7b, by 90° to 180°, and move the support base 4b. Create a gap between the chair 7b and the recessed part 6b (or the recessed part 6g of the support base 4C), and after sitting down, rotate the chair 7b in the opposite direction to the usage position and place the futon 13 on your knees. It can keep your legs warm.

Here, since the seat portion 10b is cut out to prevent the user's knees from protruding, the chair 7b can be rotated extremely smoothly after sitting down without contacting the support base 4b or 4C. Since the user does not come into contact with the frame 1, the other chair 7a.

Even if someone else is already seated in 7C or 7d, there is no risk of causing discomfort due to impact or vibration.

When leaving the chair 7b, move the seat 10 while sitting on it.
What is necessary is to rotate b by 90° to 180° and stand up in the gap created between the recess 6b of the support base 4b (or the recess 6g of the support base 4C).

In this way, the present invention is economical because it heats only a predetermined closed space, and since the user gets a cold head and warm feet, it is ideal for studying or working while seated. Since it warms you while sitting on a chair, you won't feel any pain even if you use it for a long time.Furthermore, since the device can be moved, you can use it in any desired position indoors, and there is no need for heating. It can have many effects such as being able to be used in the same way as a normal table and chair combination.

Although various explanations have been given above with reference to preferred embodiments of the present invention, it goes without saying that the present invention is not limited to the above-mentioned embodiments. The shape of the chair can also be circular or other polygonal, and the number of chairs can be changed depending on the size of the frame, etc. The shape of the part may be any shape, and the support base may be not only block-shaped but also casing-shaped. In this case, the support of the frame can be supported by fixing members such as anchor bolts. The frame may be supported directly on the floor by supports, and the blocking plate may not only be attached to the chair itself or the chair, but may also be supported via a hinge on an adjacent blocking member. It goes without saying that many modifications can be made without departing from the spirit of the invention.
