DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a footrest mounted on a leg portion of a chair.

[Conventional technology]

In general, ordinary office work and light work on a desk are performed while sitting on a chair, especially when operating recent office automation equipment, etc., stay away from the front of the equipment until the work is complete. In many cases, he has to sit on a chair for a long time because he cannot.

In the conventional chairs used for the above work, the legs of the person sitting on the chair are naturally thrown forward in front of the chair. A backrest is attached and the weight of the seated person is distributed and supported by the seat plate and backrest of the chair.

[Problems to be solved by the device]

However, if you sit on a conventional chair for a long time,
In many cases, the ischial bone of a seated person, especially the lumbar vertebra, bends back and hurt the part, or the posture of the body collapses, resulting in a so-called stoop.

Therefore, with a conventional chair, it is difficult for a seated person to maintain a correct posture and continue a work that requires tension for a long time. could not.

The main reason for this is that the weight of the upper body of the seated person is distributed and supported by the seat plate and backrest of the chair.
This is due to the structure of conventional chairs in which the legs have to be naturally thrown forward of the chair.

However, it is difficult to maintain the correct posture with the conventional chair as described above.

In view of the problems caused by the structure of the conventional chair described above, the present invention can be easily attached to the conventional chair so that a seated person can continue office work and work for a long time in a correct posture. The object is to provide a tool that can be used.

[Means for Solving the Problems]

The configuration of the present invention completed to solve the above problems is
Characterized by providing a leg support of a chair, which is provided with a leg-shaped foot rest on which the insteps or shins of the left and right feet of a person who hangs the chair abut, respectively, can be rocked back and forth. It is what

[Action]

The chair foot rest of the present invention is attached to a conventional chair, and the mounting height and the tilt of the rest are adjusted according to the length of the legs of the person sitting on the chair, etc. It can be supported on the instep side or the shin side, the weight of the upper half of the body of the person can be distributed to the femur side, the weight on the hip bone can be reduced, and the person sitting on the chair can be stably supported.

〔Example〕

1 and 2 show an example of the implementation of the footrest for a chair of the present invention.
It will be described with reference to the drawings.

FIG. 1 is a perspective view showing a state where the chair footrest of the present invention is attached to the chair, and FIG. 2 is a side view showing a usage state of the footrest on the chair shown in FIG.

In FIG. 1, 1 is a conventional chair, 2 is a seat plate of the chair 1, 3 is a backrest of the chair 1, 4 is a leg in a leg portion of the chair 1, and 5 is a leg support in the leg portion. is there.

6 is a foot rest for a chair of the present invention, 7 is a mounting portion of the foot rest 6 to the leg column 5, 7a is a locking screw for the leg support 5 of the mounting portion 7, 8a is a right foot rest, and 8b is The left foot mounting base 9a is a right support rod that pivotally supports the right foot mounting base 8a on the mounting portion 7 so as to be vertically tiltable, and 9b is a left support rod that vertically supports the left foot mounting base 8b on the mounting portion 7.

Then, the chair foot rest 6 is fixed to an appropriate position by externally fitting the mounting portion 7 to the leg support 5 and sliding it vertically on the support 5.

The fixing of the mounting portion 7 to the leg column 5 is performed by fixing the tip of the locking screw 7a screwed to the female screw (not shown) formed on the side wall of the mounting portion 7 to the leg column 5. It is performed by pressing.

Further, the right foot mounting base 8a and the left foot mounting base 8b are formed by a trapezoidal member in which a pad material is appropriately attached to the upper surface of a vertically long plate material, and the substantially central portions of the lower surfaces thereof are the right support rod 9a and the left support rod 9b, respectively. It is pivotally supported at.

Next, referring to FIG. 2, a usage mode of the footrest table 6 will be described.

In FIG. 2, P is a person sitting on the chair 1, 10 is the instep of the person P, 11 is the sciatic part, and 12 is the spine. Now, the foot of this person P is from the knee to the lower side of the seat plate 2 of the chair 1.
Bending backward at the lower part of the left and right, the left and right insteps 10 are placed on the upper surfaces of the left and right foot rests 8a and 8b.

It is desirable that the left and right foot rests 8a and 8b be continuously tilted up and down with some resistance due to the inclination of the instep or shin side of the person P who is seated, but stepwise. It may be configured to be locked to.

Thus, the posture of the person P who is seated is such that the spine 12 extends straight and at the same time, the posture of the person P leans forward toward the desk or the like. It is dispersed on the thighs and stably supported on the entire surface of the seat plate 2.

In the above embodiment, the size of the foot rests 8a and 8b is set to a length and width that allow the instep of the foot to be placed. However, the size of the foot rests 8a and 8b according to the present invention is It is optional to form the length and width so that it can be placed from the instep to the shin.

Further, the above embodiment is an example in which the foot rest 6 of the present invention is attached to the leg support 5 of a so-called swivel chair, but the foot rest 6 can be formed so as to be attached to a four-legged chair.

That is, although not shown for a four-legged chair, the attachment portion 7 of the above example is formed into a rod shape that can be detachably attached to the front and rear legs on the left and right of the four-legged chair, and To the attachment part of the left and right support rods 9a,
A beam-like support rod having a form in which 9b is integrally formed is attached, and left and right foot rests 8a and 8b are attached to the insides of both ends of the support rod so as to be swingable.

[Effect of device]

As described above, the chair footrest of the present invention can be easily attached to a chair currently in general use by one person, so that it is not necessary to manufacture a new dedicated chair, which is extremely economical. .

In addition, the posture of the person who sits down is maintained in the correct posture with the spine straightened, and the weight of the upper body of this person is stably supported on the entire seat plate of the chair. The posture is almost the same as that of a person who does not hurt his waist or loses his posture even during long-time office work or work. In addition, it can be used as an instrument for rehabilitation of such a person.

Since the footrest of the present invention rests the foot of the person sitting on the chair on the instep side or the shin of the foot, it can be used without soiling the footrest even with shoes on.

Further, the structure of the chair foot rest according to the present invention is very simple, so that it is easy to manufacture, and there is an advantage that it can be mass-produced and the manufacturing cost is low.
