In order to achieve the above-mentioned object, the invention according to claim 1 is provided in a chair having a horizontal seat plate, and the posture of a person sitting on the chair is determined by the thigh. It is intended to maintain a state of being inclined upward from the base portion toward the knee, comprising a footrest portion located forward and below the seat plate and capable of adjusting the height from the floor surface. It is a low back pain healing device for chairs.

According to a second aspect of the present invention, there is provided the low back pain healing device for a chair according to the first aspect, wherein the footrest portion can be retracted to a position where the footrest of a person sitting on the chair does not touch the foot. It is a feature.

According to a third aspect of the present invention, there is provided the back pain healing device for a chair according to the first aspect, wherein the device is detachable from the chair.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a low back pain healing device 1 for a chair according to an embodiment of the present invention, FIG. 2 is a view showing a state where the low back pain healing device 1 for a chair is mounted on a chair 101, and FIGS. FIG. 4 is an explanatory diagram of a method of using the device 1.

As shown in FIG. 2, the low back pain healing device 1 for a chair is removably mounted on a chair 101 having a horizontal seat plate 102. As shown in FIG. A plate-shaped seat portion 2 mounted on the upper portion, a pair of pipe-shaped guide members 3 and 3 extending vertically downward from both sides of the front end portion of the seat portion 2, and the guide members 3 and 3 are slidable vertically. And a foot rest 4 attached to the main body.

The footrest 4 comprises a plate-like base 5 and a pair of vertically extending rods 6, 6 pivotally attached to the rear ends of both sides of the base 5. The base 5 is moved by a known locking mechanism (not shown) into a horizontal state protruding forward as shown in FIG. 1A and a vertical state as shown in FIG. 1B. It can be stationary. The upper portions of the rods 6 are slidably accommodated in the guide member 3, respectively, and the height of the base 5 from the floor surface F (see FIG. 3) is adjusted by sliding the rods 6 up and down. can do. Positioning screws 7 are provided on the guide pipes 3 so that the rods 6 can be fixed at arbitrary positions.

Next, a method of using the low back pain healing device 1 for a chair having the above-described configuration will be described. The user is seated on the seat plate 2,
When both feet are placed on the base 5 of the footrest 4, the thighs are inclined upward from the base to the knee as shown in FIG. The inclination angle of the thigh is
The height can be easily adjusted by changing the height of the base 5 from the floor surface F. The height of the base 5 from the floor F is not particularly limited, but may be about two telephone directories (about 5 to 1).
It has been found that good results can be obtained by setting the distance to about 5 cm). When the chair 101 is rotated, the back pain healing device 1 for a chair also rotates together with the chair 101, so that the foot rests
, And the user can always maintain the posture of FIG.

As shown in FIG. 4, when the base 5 of the foot rest 4 is vertically raised, the base 5 is retracted to a position where the foot 5 does not touch the user's foot. You can sit down. Further, in the present embodiment, since the low back pain healing device 1 for a chair is detachable from the chair 101, it can be removed from the chair 101 when not in use.

The present invention is not limited to the above embodiment, but can be implemented in various forms.

For example, the low back pain healing device for a chair of the present invention may be integrally mounted on a chair.

In addition, the present invention can be implemented in various forms without departing from the technical matters described in the claims.

[0017]

As described above, according to the present invention,
The posture of a person sitting on a chair with a horizontal seat is always
Since the thigh is maintained in a state of being inclined upward from the base to the knee, low back pain can be cured.
Also, by changing the height of the footrest from the floor,
The inclination angle of the thigh can be easily adjusted.

According to the second aspect of the present invention, since the footrest can be retracted to a position where the footrest of the person sitting on the chair does not touch the foot, the chair can be seated in a normal posture.

According to the third aspect of the present invention, since it is detachable from the chair, it can be detached from the chair when not in use, which is convenient.
