Description

[Detailed description of the invention] (Industrial application field) This invention can be attached to the legs of a Japanese-style kotatsu (hereinafter referred to as kotatsu legs) with relatively low heights, such as round bar legs, and adjusted to a predetermined height. This relates to adjustable legs. Furthermore, the table is not limited to the kotatsu legs, and may be a table with low legs.

(Prior art) In the case of conventional Japanese-style kotatsu legs, for example, short legs can be attached structurally.
If long legs are attached to this kotatsu, it will wobble and be unstable.

(Problem to be solved by the invention) Therefore, this invention utilizes a Japanese-style kotatsu with legs attached to short circles, and can be used as a Western-style kotatsu by attaching adjustable legs that fit snugly. It provides height adjustable legs.

(Means for Solving the Problems) In order to achieve the above object, this invention has an upper end 10a having a diameter into which the leg 4 is inserted, a recess 12 at a right angle position in the upper end, and a recess 12 in the recess. A pipe-shaped adjustment leg 10 is provided with a screw hole 11 at the lower end thereof, and a leg cap 15a made of rubber or synthetic resin is attached to the lower end, and screw holes 13a are provided on the left and right at intervals of the screw holes 11 of the pair of adjustment legs 10. It has a mounting part 13b that engages with the recess 12, and is composed of a connecting rod 13 that connects the pair of adjusting legs 10. After inserting the leg 4 into the upper end 10a of the adjusting leg 10, the adjusting legs 10 are connected to the connecting rod. 13 and fixed with screws 14.

Hereinafter, an embodiment of this invention will be explained based on the drawings.

Kotatsu with height-adjustable legs according to this invention 1
This is composed of a commercially available kotatsu 2, adjustable legs 10 into which the kotatsu legs 4 of the kotatsu 2 are inserted, and a connecting rod 13 that connects the adjustable legs to each other.

The kotatsu leg 4 is generally a circular or rectangular rod-shaped body that is processed to be slightly thinner than the kotatsu attachment part, but the upper end 10a of the adjustable leg 10 allows the entire kotatsu leg 4 to be inserted easily when inserted. It is made of a pipe with a diameter that is large enough to prevent it from coming out.

Note that the lower end portion of the adjustable leg 10 may be thinner than the upper end portion. Alternatively, the part into which the kotatsu legs 4 are inserted may be made hollow, and the other parts may be made of a rod-shaped material having the necessary strength, by finishing both ends of the round bar as shown in Figures 3 and 4 in order to provide strength. It is.

Further, the cross section of the upper end portion 10a is set to correspond to the cross-sectional shape of the kotatsu leg 4.

The upper end portion 10a is provided with recesses 12 at positions perpendicular to each other slightly downward from the upper edge, and screw holes 11 are provided in the recesses 12.

In addition, the adjustment leg 10 may be a vinyl chloride pipe or a metal pipe, and the surface of this pipe may be colored.

In addition, the length of the adjustable legs 10 can be set to any length depending on the purpose. For example, when used while sitting on a sofa, a length of about 51 cm is best, and it is selectable. Various lengths are available.

The kotatsu 2 is equipped with a heater section 5 with a wire mesh cover, a cord 6, a temperature adjustment switch 7, an intermediate switch 8, a plug 9, and a hanging tool 9a.

On the other hand, a non-slip leg cap 15a made of rubber or synthetic resin is attached to the lower end of the adjustable leg 10.
A leg cap 15a that fits into the leg portion 15 or a leg cap 15a that covers the leg portion 15 may be used.

Next, the connecting rod 13 connects the pair of adjusting legs 10 and prevents them from wobbling.
This connecting rod 1 is made of the same material as 0.
Attachment portions 13b having screw holes 13a at both ends of 3.
is provided. Note that this connecting rod 13 may be attached to the adjustable legs 10 on four sides, or one side may be removed and three sides may be connected.

The mounting portion 13b has a shape corresponding to the recess 12, and when the screw 14 is secured to the recess 12, the mounting portion 13b
The surface of 3b is prevented from protruding, and this screw 1
4 so as not to touch the surrounding kotatsu futon 2a or clothing, or cause injury to the human body.

Furthermore, for the same reason, a screw whose head does not protrude is used for the screw 14.

When installing it on the kotatsu 2, after inserting it into the upper end 10a of the kotatsu leg 4 and attaching it securely,
Attach the mounting portion 13b of the connecting rod 13 to the recess 12 with the screw 14.
It can be assembled by stopping.

(Effects of the invention) According to this invention configured as described above, the kotatsu legs attached to the kotatsu are used to attach the adjustable legs to the kotatsu legs, and in addition, the adjustable legs are connected to each other by connecting both ends of the round bar. Since it is connected with a rod, the kotatsu will not wobble, and if you hang the kotatsu futon,
It can be used in the same way as a traditional kotatsu. Moreover, since there are many adjustable legs of arbitrary lengths, you can select one of them, and the height can be adjusted by using the adjustable legs of the length according to the usage condition.

Furthermore, the adjustable legs can be easily and quickly attached, and can be easily removed when not in use, making this an extremely useful device.
