Description

[Detailed Description of the Invention] This invention relates to an improvement of a chair that allows muscle exercises, particularly those of the upper body such as arms and shoulders, to be performed while sitting on the chair.

In general, office workers and workers who mainly do manual labor spend most of the day working while sitting in a chair, which results in a lack of exercise and a feeling of mental and physical fatigue. It's something to remember.

This idea was developed by the above-mentioned clerks and workers on the spot.
The purpose of this chair is to improve the chair so that it is easy to exercise the upper body, mainly exercising the muscles of the arms and shoulders, thereby improving health and work efficiency.

Second, this invention is an improvement on the conventional general chair, and can be used in general households, and in particular, provides a chair that doubles as an exercise tool for people with physical disabilities at home. This is what I am trying to do.

To explain an embodiment of this invention with reference to the drawings, FIG. 1 shows a general office rotating chair A comprising a master member 1, a backrest member 2, and leg members 3. A support tube 5 of the armrest member 4 is fixed.

One end of the armrest member 4 is rotatably supported relative to the master member 1 so as to open outward.

Further, on the other end of the armrest member 4, there is removably screwed an extensible rod-like member B provided with an elastic member 6 such as a spring having sufficient strength to resist arm strength and restore its original shape. There is.

Note that 7 is a fixture for the armrest member.

2 to 4 show another embodiment, in which a mounting rod 11 of a rod-like member B is provided at the tip of the armrest member 4 so that it can rotate relative to the armrest member 4. , are fixed with screws 12 via a meshing device C.

The distal end of the mounting rod 11 has a U-shaped opening 13, and a rod-shaped member B is rotatably supported under the U-shaped opening 13 via a bearing 14 as shown by the arrow.

Further, a fixing ring 16 having an outward U-shaped opening 15 is fixed to the upper side of the tip of the mounting rod 11.

Furthermore, when the rod-shaped member B is rotated from the temporary line position to stand up, a rotating ring 18 having a U-shaped opening 17 that coincides with the opening 15 of the fixing ring 16 is engaged with the fixing ring 16. It matches.

Therefore, the rod-shaped member B is erected, the rotating ring 18 is rotated, and the U-shaped opening 17 is connected to the opening 15 of the fixed ring 16.
The rod-shaped member B is fixed by positioning it on the opposite side.

In order to securely fix the ring, the fixed ring 16 and the rotating ring 18 may be screwed together.

Although not shown, in the case of a chair that does not have the armrest member 4, the mounting rods 11 of the second embodiment may be directly attached to the left and right ends of the master member 1.

To use the chair of this invention, first, the rod-shaped member B is mounted or erected, stretched to an appropriate height, and then the armrest member 4 or the mounting rod 11 is opened and fixed at an appropriate position.

Next, bend your arm into a Y-shape, grasp the tip of the rod-shaped member B, and push or surround it in the front and back, right and left, or in a circle against the restoring force of the elastic member 6. You can easily exercise your muscles.

Also, by sitting shallowly on a chair, stretching the rod-shaped member B as much as possible within reach, grasping its tip, and tilting or twisting the entire upper body back and forth and left and right against the restoring force of the rod-shaped member B, You can train your arms, shoulders, chest, stomach, and back muscles.

Performing these exercises at the same time also has the effect of improving the function of internal organs.

This idea is a slight improvement on the conventional chair as mentioned above, without sacrificing its original function as a chair.
It can be used as an exercise tool for the upper body, including arm and shoulder muscle exercises.

Therefore, without having to prepare special exercise equipment or health equipment, it is extremely easy to use, not only for general office workers and workers, but also for housewives while watching TV, and even for people with physical disabilities. It is something that can be used and provides effective exercise.

Furthermore, since the chair is a daily necessity, it can be used as a chair even when not being used as an exercise tool, so it has the advantage that it does not require the effort of putting it in and taking it out or requires a storage space.
