Description

  The present invention relates to a chair used for a table with a heating device, and more particularly to a configuration for preventing outflow of warm air from a lower portion of a seat portion of the chair.

Conventionally, in order to be able to warm the space under the table (such as the feet of the user) in winter or the like, a heating device has been provided on the lower surface side of the top plate, and a table cover has been installed so that it can be used as a kotatsu. A table with a heating device is used. In such a table with a heating device, various chairs suitable for the height of the table can be used. However, depending on the shape of the legs of the chair, an opening is formed at the lower part of the seat of the chair, and the heating device Therefore, there is a problem that the heating efficiency is reduced due to the outflow of warm air from the lower space of the table heated to outside and the inflow of cool air from outside.
In this regard, for example, it is considered to provide a cloth member that hangs down from the seat surface of the seat to close the opening, or to provide a plate member that closes the opening between the legs.

  However, in the case where a cloth member or a plate member hanging from the seat is provided, a chair provided with a cylinder (post) that supports the seat so as to be able to move up and down and rotate may obstruct the lifting and lowering operation and the rotation operation. In addition, depending on the orientation of the seat in accordance with the turning operation, a gap is formed in the lower space of the seat. Moreover, in the case of a cloth member hanging from the seat surface, there is a risk that the user may be displaced when the user is seated. Further, in the case of a chair provided with casters on the legs, a gap is formed in the caster portion, so that there is a problem that the warm air in the lower space flows out from the gap and a problem that a cloth member is entangled with the caster. On the other hand, when no casters are provided, movement of the chair becomes difficult, and the movement of the chair may damage the floor of the room.

  The present invention has been made to solve the above problems, and relates to a chair used for a table with a heating device, which is provided with a support and a caster that supports the seat in a vertically movable and rotatable manner. It is an object of the present invention to provide a chair in which a gap formed at a lower portion is made as small as possible, so that outflow of warm air from a lower space of a table can be appropriately prevented.

  In order to solve the above-mentioned problem, the present invention provides a table with a heating device comprising a seat, a column for supporting the column so as to be able to move up and down and rotatable, and an upper opening box-shaped base on which the column is erected. Chair for closing a space between the seat and the footrest, and a substantially cylindrical windshield member partially or wholly formed so as to be housed in the footrest, It is characterized in that it is mounted so as to surround the outer periphery of the column, and that a caster is provided on the lower surface of the footrest so that the caster can be stored in accordance with the downward movement of the footrest due to the load on the seat.

According to the above configuration, the table chair with the heating device of the present invention has the following effects.
(1) Since a windshield member is provided to close the space between the seat and the footrest, the opening normally formed in the leg of the chair can be closed, and the outflow of warm air from the lower space of the table can be appropriately performed. , The heating efficiency can be increased. In this case, since the windshield member is attached to the lower surface of the seat portion, there is no hindrance when the user sits on the seat portion, and the position does not shift due to the operation of the user. In addition, since a substantially cylindrical windshield member surrounding the column supporting the seat portion is provided, no gap is generated in the lower portion of the seat portion regardless of the orientation of the seat portion due to the rotation operation, and the table It is possible to appropriately prevent the outflow of warm air from the lower space.
(2) In addition, the leg base 3 is formed in a box shape with an upper opening, and a part or all of the windshield member can be stored in the leg base 3 in accordance with the lowering operation of the seat. In addition, it is possible to appropriately prevent the outflow of warm air from the lower space of the table without obstructing the raising / lowering operation of the seat.
(3) In addition, since the casters are configured to be housed in the lower part of the footrest 3, the chair can be easily moved, and the gap caused by the provision of the casters can be eliminated. Etc. can be appropriately prevented.

Hereinafter, a chair for a table with a heating device according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view illustrating a chair according to the present embodiment, FIG. 2 is a perspective view illustrating a seat lower surface side of the chair according to the present embodiment, and FIG. 3 is a perspective view of the chair according to the present embodiment. It is a principal part side view which shows a footrest.
As shown in each of the drawings, a chair 1 according to the present embodiment is configured by a seat 2 having a backrest and an armrest, a gas-pressure cylinder, and the like, and a column (for supporting the seat 2 to be able to move up and down and rotate). (Not shown) and a footrest 3 on which the column is erected.
In the present embodiment, a substantially cylindrical windshield member 4 surrounding the outer peripheral side of the column is provided so as to close the space between the seat portion 2 and the footrest 3. A plurality of casters 5 are provided on the lower surface side of the footrest 3.
The windshield member 4 is formed using, for example, a soft member made of a resin material such as PVC having a heat insulating property. The outer diameter and the height are set so that the seat 2 can be accommodated, so that it does not hinder the raising / lowering operation and the rotating operation of the seat 2. In this case, it is preferable that the outer diameter of the windshield member 4 be large enough to contact the inner peripheral surface of the leg base 3 in order to minimize the gap generated between the seat 2 and the leg base 3. Further, it is preferable that the height of the windshield member 4 is such that no gap is formed between the lower end of the windshield member 4 and the footrest 3 when the seat 2 is fixed at the uppermost position.
As shown in FIG. 2, on the lower surface of the seat portion 2, a column mounting portion 2 a is provided at a substantially central position, and a plurality of surfaces corresponding to a surface fastener (not shown) provided at an upper end portion of the windshield member 4. The fasteners 2b are arranged and fixed at predetermined intervals so as to form a substantially circular shape centering on the column mounting portion 2a.
The footrest 3 includes casters 5 near four corners on the lower surface, and is configured to be movable in the front-rear direction. A shaft (not shown) that supports the caster 5 is supported via an elastic member such as a spring. The elastic member opposes the weight of the chair 1 and pushes up the chair 1 as a whole. Part or all protrude from the lower surface of the footrest 3. On the other hand, when the user sits on the seat 2, the elastic member contracts due to the weight, and as shown in FIG. The casters 5 are stored in the storage section 3a.

A method of using the chair 1 according to the present embodiment configured as described above will be described.
As shown in FIG. 3, before the user is seated, the caster 5 protrudes from the lower surface of the leg base 3 and can rotate as shown by a solid line by pushing the whole chair upward by the elastic member. Therefore, the chair 1 is movable in the front-back direction.

You. As a result, the lower surface of the footrest 3 comes into contact with the floor surface, so that the movement of the chair 1 is prevented by the frictional force.
In addition, since the windshield member 4 is attached between the seat 2 and the footrest 3, the gap between the feet is substantially closed, so that the outflow of warm air from the space under the table is appropriately prevented. It is possible to do.
In the summer, by removing the windshield member 4 attached to the lower surface of the seat 2, ventilation at the feet can be improved.

As described above, the chair 1 for a table with a heating device according to the present embodiment includes the windshield member 4 that blocks the space between the seat portion 2 and the footrest 3. Since the opening formed can be closed and the outflow of warm air from the lower space of the table can be appropriately prevented, the heating efficiency can be improved. In this case, since the windshield member 4 is attached to the lower surface side of the seat 2, there is no hindrance when the user sits on the seat 2, and there is no displacement or the like due to the operation of the user. . In addition, since the substantially cylindrical windshield member 4 surrounding the column supporting the seat portion 2 is provided, a gap may be formed in the lower portion of the seat portion 2 regardless of the orientation of the seat portion 2 due to the rotation operation. Can be prevented. Further, since the footrest 3 is formed in a box shape with an upper opening, and a part or all of the windshield member 4 can be stored in the footrest 3 in accordance with the lowering operation of the seat 2, This does not hinder the raising / lowering operation of the seat portion 2 and can more appropriately prevent the outflow of warm air from the lower space of the table.
Further, since the casters 5 are configured to be able to be stored in the lower part of the footrests 3, the chair 1 can be easily moved, and the gaps caused by the provision of the casters 5 can be eliminated. Etc. can be prevented more appropriately.

In addition, the chair for the table with the heating device according to the present invention is not limited to the one according to the embodiment, and various changes can be made without changing the gist.
For example, the attachment method of the windshield member is not necessarily limited to the hook-and-loop fastener, and another method such as a double-sided adhesive tape may be used. Further, the windshield member is not limited to the soft resin material, and other members such as a cloth member and a synthetic member may be used.
