Abstract

PURPOSE:To make a low table adjustable in height corresponding to user's purpose or figure by providing a lifting device capable of moving the low table up and down. CONSTITUTION:A nut 4 and a threaded rod 5 serve as a female screw and a male screw respectively and when the threaded rod 5 is turned, the nut 4 is moved up or down corresponding to the rotating direction. To settle a low table 1 at a desired height, the threaded rod 5 is turned in the normal direction to move low table receptacles 3 upward and reversed to move the receptacles 3 downward. Therefore, the low table 1 can be used as a dining table or a writing desk or adjusted to a desired height corresponding to user's sitting height. When the low table 1 is descended to the lower limit, the low table 1 including a top board 1b can be easily stowed in a recessed foot warmer main body 1.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a kotatsu that is installed by opening the floor of a room or the like.

0002

[Prior Art] The conventional horigotatsu shown in FIG.
The leg portions 101a of 01 are fixed to a rectangular lower frame 108, and the lower frame 108 is supported by a frame 104 on the outer periphery. The kotatsu main body 103 provided at the lower part of the lower frame 108 has a box shape with an open top, and has a drainboard 102 at the bottom.

0003

[Problems to be Solved by the Invention] Due to the above structure, the height of the low table, that is, the height from the floor 110 to the top plate 101b, is constant, and depending on the purpose of use and body shape of each person, it may be too high or it may be too high. Too low and not convenient to use. An object of the present invention is to provide a horigotatsu whose height can be adjusted according to the user's purpose and body shape.

0004

[Means for solving the problem] The horigotatsu of this invention is
The shape is such that the low table can be stored inside the main body of the kotatsu. A low table support for supporting a low table is provided inside a horigotatsu main body so as to be freely raised and lowered, and a lifting device for driving the low table support up and down is provided inside the horigotatsu main body. A pair of approximately L-shaped lifting device storage parts with the L-shaped lower tips facing the center are arranged on both sides of the kotatsu main body.

[0005]

[Function] The horigotatsu of this invention allows you to adjust the height of the low table as you like by raising and lowering it freely, and you can easily store the low table including the top board inside the horigotatsu body. can.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1 to 4. The horigotatsu of this embodiment shown in FIGS. 1 and 2 has a grating 2 provided at the bottom of the horigotatsu main body 12,
A low table support 3 that supports a low table 1 and is movable up and down is installed so as to protrude inward from an approximately L-shaped lifting device housing part 6 of a kotatsu main body 12. The low table 1 has a shape that can be stored inside the horigotatsu main body 12, and the total height including the lower frame 8 and the top plate 1b is as follows.
It should be shorter than the lifting range of the low table support 3. Four table supports 3 are provided at the four corners so as not to get in the way of people's legs. A lifting device 9 for driving the table support 3 up and down is provided inside the kotatsu main body 12.

FIGS. 3 and 4 show a vertical sectional view and a horizontal sectional view of the lifting device 9, respectively. The lifting device 9 is installed inside a pair of approximately L-shaped lifting device housings 6 with the L-shaped lower tip 6a facing the center of the kotatsu main body 12, and the motor 13 and The speed reduction mechanism 14 is housed horizontally. Therefore, compared to the case where both are installed in a straight line in the vertical direction, the floor surface is increased by the amount occupied by the motor 13.
It is possible to set a deep elevation range from 0. The low table support 3 supports the low table 1 via a base 30 fixed to one end 31, and a nut 4 is provided at the center of the other end 32. The nut 4 is threadedly engaged with the threaded rod 5. The threaded rod 5 is supported at both ends by bearings 15 fixed to the top and bottom of the lifting device storage section 6, respectively, and is connected to a drive source constituted by a speed reduction mechanism 14 consisting of a pair of helical bevel gears and a motor 13. are doing. A constricted portion 33 is formed between both end portions 31 and 32, and is inserted into a vertical elongated hole 7 bored in the elevating device storage portion 6. By providing the constricted portion 33, the elongated hole 7 can be made into an elongated shape, and dust and the like can be prevented from entering the elevating device 9.

[0008] The operation will be explained. The nut 4 and the threaded rod 5 have a female thread-male thread relationship. Therefore, when the threaded rod 5 is rotated, the nut 4
rises or falls. When setting the low table 3 to a desired height position, the low table support 3 is raised by rotating the threaded rod 5 in the normal direction, and lowered by rotating the low table 3 in the opposite direction. Explain how to use it. The height of the low table can be set arbitrarily depending on the purpose of use and body shape of each person, such as whether it is used as a dining table, a desk, or the sitting height. In addition, when the low table support 3 is lowered and set to the lower limit, the top plate 1b
The entire low table 1 including the kotatsu can be easily stored inside 11 of the kotatsu main body 12.

[0009]

Effects of the Invention Since the sunken kotatsu of the present invention is equipped with a lifting device for driving the low table up and down, the height of the low table can be arbitrarily adjusted according to the purpose of use and body shape of each person. By simply setting the low table to the lower limit, the entire low table including the top plate is incorporated into the main body of the kotatsu, making it easy to store the low table. Furthermore, since the approximately L-shaped lifting device housing section is provided within the main body of the kotatsu, the range of elevation is widened, the space inside the kotatsu main body can be used effectively, and maintenance and inspection of the lifting device is easy.
