Description

[Detailed description of the invention] This invention relates to the improvement of a chair, and is particularly designed to allow exercise of the legs and hips.

Originally, walking, running, and jumping are the basic and best ways to exercise the legs and hips, but with the development of cars and other means of transportation, there are fewer opportunities for such activities, and the density of office work has increased.
I tend to lack exercise.

Therefore, recently various health tools have been developed, but because of their special shapes, their use is limited to health tools, and it is difficult to use them at regular workplaces or at home during breaks from work. Ta.

This invention is a slight improvement on the conventional general chair, and it can be easily used at any time as needed without compromising the function of the conventional chair, and allows you to exercise your legs and hips. This is what I did.

An embodiment based on this invention will be described with reference to the drawings. A frame 2 having a concave cross section is fixed to the lower central part of the platen member 1.

This concave frame 2 may be formed integrally with the platen support member 1'.

A rotary tube 3 is suspended from the bottom surface 21 of the concave frame 2, and is rotatably supported by a support 4' of a leg member 4 via a bearing or the like like a conventional rotary chair.

Further, sliding elongated holes 5 are provided in both side walls 22 of the concave frame 2, and a support rod 6 is telescopically inserted into the support rod 6. Fixed at any angle in the hanging position (details of the fixing device are not shown).

) is now possible. Petals 88, 8b are rotatably supported on the left and right sides of the tip of the petal rod 7,
Betaru 88 on either the left or right side is the betal 88 on the other side.
It can be fixed by rotating 180 degrees to the same side.

This is to make it easier to store the petal rod 7 under the platen member 1.

Furthermore, the petal rod 7 has the required pin holes 90, 9°, 9
3, 94 are provided, and are adjustable and fixed with pins 11 in the fixing hole 10 provided at the tip of the support rod 6.

Note that the bottle hole 9 is a hole in which the entire length of the petal rod 7 is inserted into the support rod 6, and the person using this chair is asked to adjust the length of the petal rod 7 and the support rod 6. - If the structure is such that it can be stored under the platen member (for example, Fig. 3), the bottle hole 9□ is not necessary.

In addition, the length of the petal rod 7 is adjusted by connecting the support rod 6 with a pin. The length l from the front end of the platen member 1 to the petal position may be adjusted.

Fig. 3 shows another embodiment in which the support rod is folded and attached to the lower part of the platen member, and since there is no obstruction under the platen member 1, the petal rod 7 is pulled out. It can be rotated and stored.

Reference numeral 13 indicates a hook for fixing the support rod when folded or folded.

Since this invention has the above-mentioned structure, when using it as an original chair, the petal 8 should be placed on the same side (the second
(see figure) and rotate toward the petal rod 7 side, insert the petal rod 7 into the support rod 6, align the pin hole 9□ with the fixing hole 10, and fix it with the pin 11.

Next, by loosening the fixing device 12 of the support rod 6, storing the support rod 6 in the concave frame 2, and fixing it 12', the chair can be used in exactly the same way as a conventional chair.

Also, when performing leg and hip exercises, reverse the above operations, i.e.,
Loosen the fixing device 12', pull out the support rod 6 from the concave frame 2, then pull out the petal rod 7 from the support rod 6 by using the pin 11, and fix it in the pin hole at the position that matches your height. Replace one side of 8 to the normal position.

Next, the strength of the movement is selected and fixed by the angle of the support rod 6.

All you have to do is sit on a chair and rotate the bicycle pedals with your feet.

In this case, if the support rod 6 is placed in a horizontal position, the strongest exercise can be performed, and the entire body can be exercised, not only the feet but also the lower back and abdomen.

As described in detail above, this idea allows you to easily exercise your legs and hips at work, at home, or anywhere a chair is installed, without compromising the original function of the chair. Moreover, since the structure is simple, it is inexpensive and can be used as a general chair in many workplaces and homes, and its practical effects are extremely large.
