Description

[Detailed Description of the Invention] This invention relates to an improvement of a chair, in which a rowing exercise device is attached to an armrest member or a master member so as to allow exercise of the arms and upper body.

Conventional rowing exercise equipment has been developed as specific exercise equipment or health equipment, so it is not versatile and can only be used by healthy people.

This idea is a conventional general chair with some improvements and a rowing exercise device attached to it.It is normally used as a general chair, but can also be used as an exercise or health tool when necessary. This is what I did.

To explain the embodiment of this invention in detail with the drawings, in a chair A, an armrest member 2 supported by an armrest support rod 1 includes an armrest support 3 and a cover part 4 including an armrest cushion.
It is divided into two parts, and is hinged at the rear so that it can be opened and closed.

At the front of the armrest support 3, there is a base 5 of a rowing rod support rod 5;
is removably fitted to a polygonal shaft 6 implanted in the armrest support 3.

On the other end 5□ of the rowing rod support rod 5, the rowing rod 7, which is configured to be extendable and retractable by a grip 7□ and a fulcrum adjustment rod 72, is rotatably supported with the grip facing inward. .

Further, a spring 8 is engaged with one end of the fulcrum adjustment rod 7□.
The other end of the spring 8 is locked to the base 5□ of the rowing rod support rod 5.

In the figure, 9 is a fixed handle of the rowing rod support rod, 10 is a stopper of the rowing rod, 11 is a support shaft of the rowing rod, and 12 is a master member.

This device has the above-mentioned structure, and if you hold the grips 7□ of the left and right rowing rods with each hand on a chair and pull each rowing rod 7 toward you against the tension of the springs 8, the springs will release. 8
is the movement Y' of the fulcrum Y, which is displaced around the support shaft 11, and
Also increases drag.

Therefore, by repeating this rowing exercise, you can exercise your upper body, especially your arms.

Incidentally, the drag of the rowing rod can be adjusted by extending and contracting the fulcrum adjustment rod and changing the length L.

When using it as a general chair, open a part of the armrest cover and remove the rowing rod 7 from the support shaft 11 as shown in Fig. 2, then loosen the fixed handle 9 and remove the rowing rod support rod 5. ,
By changing the clothes so that it is positioned on the armrest support 3, it can be stored in the armrest member as shown in FIG.

Figures 5 and 6 show the rowing rod 7 facing upward (from 15° to 4°).
The rowing rod support rod is formed in a truss shape and protrudes from the armrest member 2, seat 4, and plate member 12.

With this invention, as described in detail above, by making an extremely simple modification to a conventional chair, rowing exercise can be performed, and the arms and upper body can be exercised effectively.

Furthermore, when the chair is not used as an exercise tool, it can be removed or stored inside the armrest, so its function as a chair is not impaired.

Furthermore, since the boat can be rowed while seated, it can be easily used even by people with physical disabilities, and its practical effects are extremely large.
