Description

  The present invention relates to a footrest and a stretching method using a chair-type massage machine provided with an air bag for massaging the footrest and / or the tip of the footrest.

  In a chair-type massage machine equipped with a footrest, stretch the upper body and legs by tilting the backrest backward while restraining the lower leg stored in the footrest or by moving the footrest up and down. Has been proposed (Patent Document 1).

JP 2003-210270 A

In the case of the above-mentioned patent document 1, the state of the seat when stretching the leg is the state when the user gets into the chair type massage machine, that is, the seat is substantially parallel to the floor surface on which the chair type massage is installed. Since it is in a state of being relaxed, it lacks a sense of relaxation.
Further, since the weight of the user acts in a direction substantially perpendicular to the floor surface with respect to the seat, the effect of causing the weight of the user to contribute to the stretch is small.
In addition, some footrests have inflated shin rests and toe rests, and the distance between the foot rests and the seats can be adjusted according to the length of the lower leg of the user. However, even when trying to widen the space between the footrest rest and the seat, the footrest rests on the floor when the footrest is lowered during the pivoting movement, and the footrest rest cannot be extended. Arise.
In addition, there is a risk that the footrest portion collides with a foreign object on the floor surface or causes a trouble of biting the foreign object.
This invention clarifies the stretch method by a chair type massage machine which can solve the said problem.

Claim 1 comprises a reclining seat (12) and a backrest (13), and a footrest (2) that can be moved up and down by rotating around the vicinity of the front end of the seat. And / or air bags (61) (62), (63) (64) for massaging the toes, control of the reclining device of the seat (12), backrest (13) and footrest (2) and air A stretching method by a chair type massage machine having a control unit for controlling expansion and contraction of a bag,
Before inflating the air bag of the footrest (2) and fixing the shin and / or the tip of the footrest (2), the footrest (2) is rotated up and down to stretch the leg of the user (12 ) So that the front part is lifted and the backrest part (13) is tilted backward.

  Claim 2 is the stretching method according to claim 1, wherein the footrest (2) of the chair type massage machine is composed of an inflated shinrest part (3) and a footrest part (4), with respect to the seat part (12). A footrest rest portion (4) is provided so as to be able to approach and separate and to be positioned.

  Claim 3 is the stretch method according to claim 1 or 2, wherein the seat rest (12) is reclined with respect to the floor surface F on which the chair type massage machine is installed until it is inclined 25 ° to 35 °. (2) is turned up and down.

The stretch method using the chair-type massage machine according to claim 4 includes a reclining seat part (12), a backrest part (13) reclining relative to the seat part, and a left and right on the seat part. With a waist airbag (65) (65)

The stretch method of the present invention sits on a chair type massage machine (1) in a reclining state so that the front part of the seat part (12) is lifted and the backrest part (13) is tilted backward. Therefore, compared to the case where the seat portion (12) is substantially parallel to the floor surface and the backrest portion (13) is standing upright, the user is leaning on the backrest portion (13). Legs can be stretched in a relaxed posture that leans backwards.
In addition, since the leg portion is stretched with the front portion of the seat portion (12) raised, the weight of the user always acts backward on the seat portion (12) and faces backward with respect to the leg portion. Force acts. For this reason, the stretch effect with respect to a leg part can be heightened.
In the present invention, when the interval between the seat portion (12) and the footrest rest portion (4) can be adjusted and the interval between the seat portion (12) and the footrest rest portion (4) is increased, the seat portion (12 ), The leg is stretched by rotating the footrest (2) up and down in a state where the front part is largely lifted, that is, a large space is created between the footrest (2) and the floor F. Therefore, it is possible to prevent the footrest (2) from hitting the floor surface F, colliding with a foreign matter on the floor surface, and biting the foreign matter.

In the footrest (2), the opening angle of the footrest portion (4) with respect to the inflated shinrest portion (3) is larger than that in the reset state by the action of the link mechanism (22).

Each airbag and each reclining drive device of the chair type massage machine is a necessary reclining device by operating a control unit (not shown) and various operation buttons of an operation unit (not shown) such as a remote controller. Can be operated, and a necessary airbag can be expanded and contracted to massage a desired part in a desired posture, or various massage courses can be selected.
About the control method of these massages and a massage course, since various proposals are made and it is well-known, description is abbreviate | omitted.

Next, a stretch course will be described in which the user sits on the seat (12), leans on the backrest (13), and stretches the leg of the user who inserted the lower leg into the footrest (2).
As shown in FIG. 3, the seat part (12) and the backrest part (13) are reclined, and the seat part (12) is inclined by approximately 30 ° with respect to the floor surface. This 30 ° angle is not absolute, and if it is 25 ° to 35 ° from experience, it is possible to obtain a good body feeling for sitting and relaxing as described below.

  The footrest (2) is lifted with the reclining of the seat (12), and a large space exists between the footrest (2) and the floor surface F. The position of the footrest (2) at this time is the leg stretch start position.

  In the case of the embodiment, since the seat (12) and the backrest (13) are operated by separate reclining drive devices (6) and (7), the backrest (13) has an angle with respect to the seat (12). In the initial state (reset state), that is, when the user gets into the chair-type massage machine, the reclining angle is the same as or larger than the angle formed by the seat (12) and the backrest (13). To control.

With each airbag (63) and (64) of the footrest part (4) inflated and the foottips fixed to the footrest (2), the footrest (2) is attached to the front end of the seat part (12). As shown by an arrow A in FIG. 3, the two pivot points 20 and 21 that are close to each other, that is, the vicinity of the front end portion of the seat portion 12 are pivoted up and down.
At this time, the footrest (2) is controlled so as not to fall below the leg stretch start position and to be above the extension of the sitting surface of the seat (12).
In raising and lowering the footrest (2), when the footrest (2) descends, the leg part of the user whose leg is fixed to the footrest (2) is pulled to stretch the leg part.

As in the embodiment, when the footrest (2) is lifted, when the opening of the footrest rest portion (4) is larger than the inflated shinrest portion (3), the foottip is moved to the footrest rest portion (4). If fixed to, the force to stretch the instep acts, so the stretching effect is enhanced.
Moreover, in the present invention, when the footrest (2) is turned up and down, the seat (12) is reclined and the front part is lifted greatly, so that the weight of the user is relative to the seat (12). Since the pulling force acts on the thigh of the user in the rearward direction, the leg of the user can be stretched more effectively.
In the embodiment, the backrest (13) is also tilted backward compared to the reset state of FIG. 4 so that the angle formed with the seat (12) is the same as or larger than that of the reset state. It can be firmly received by the backrest (13), can keep the whole body relaxed, and can effectively stretch the legs while relaxing.
The time required for the stretch course is set by the control unit as a timer.

In the above embodiment, only the foot of the user is fixed to the footrest (2), but the inflated shin is also attached to the footrest (2) by the airbag (61) (62) of the inflated shinrest portion (3). It may be fixed.
Furthermore, it can also be implemented by fixing the footrest (2) only to the inflated shin.
However, it is more effective to fix the toes far from the knee.

In the embodiment, when the control unit ends the leg stretch course or shifts from the course of the leg stretch course to another course, the footrest (2) is placed at the start position of the leg stretch course (leg). Control to automatically return to the stretch start position).
This is because if the leg stretch course is terminated in the middle of the course or if the course is shifted to another course during the course, the footrest (2) position is not constant and the seating posture in the next course is unstable. When stretching or stretching, you may feel uncomfortable, and this problem can be solved by returning the footrest (2) to the starting position of the leg stretch course.

It should be noted that the distance between the inflated shin rest part (3) and the toe rest part (4) of the footrest (2) can be adjusted according to the length of the lower leg part of the user, etc. The structure which can adjust the space | interval of a part (12) and a footrest rest part (4) is employable.
As in the present invention, the footrest (2) is reclined and the front is greatly lifted, that is, a large space is created between the footrest (2) and the floor F. When the leg is stretched by rotating up and down, the front part of the seat (12) is lifted even if the distance between the footrest (4) and the seat (12) is increased. Since the leg stretch course is started, it is possible to prevent the footrest (2) from hitting the floor surface F, colliding with a foreign material on the floor surface, or biting the foreign material.

6 and 7 show a chair type massage machine that can fold the footrest (2) and store it under the seat (12) and can stretch the Achilles tendon.
The footrest (2) is composed of an inflated shinrest portion (3) and a foot tip rest portion (4) in the same manner as described above, and the inflated shinrest portion (3) is a fulcrum (20) on the seat portion (12). It can sneak under the seat (12) by rotating around the center.
The footrest portion (4) is supported so as to be rotatable about a connecting portion (40) located at the lower end of the inflated shinrest portion (3).
In the embodiment, a roller (not shown) that rolls on the floor surface is attached to the footrest portion (4).

As shown in FIG. 7, the footrest retractor (80) connected to the inflatable shinrest portion (3) is rotated around the fulcrum (20) by the footrest retracting device (80). When retracted downward, the footrest rest portion (4) follows this and is retracted below the seat portion (12) and stored.
At this time, since the toe rest part (4) forms a V-shape with an angle of 90 ° or less with respect to the inflated shin rest part (3), the toe is bent to the shin side, and the Achilles tendon is stretched. Is made.
In addition, air bags (61) (62) (63) (64) are arranged in the inflated shin rest part (3) and the footrest rest part (4) as in the embodiment of FIG. When stretching the Achilles tendon, these airbags (61), (62), (63), (64), especially the airbags (63), (64) of the footrest part (4), are inflated and the toes move. It is fixed as if
It should be noted that the joint part (40) of the inflated shin rest part (3) and the foot toe rest part (4) is connected to the floor of the foot toe rest part (4) regardless of the inclination angle of the inflated shin rest part (3). For example, a long hole and a shaft that fits into the long hole (both not shown) are configured so as to be movable parallel to the surface.

  8 and 9 show that the waist of the user is clamped and fixed from both the left and right sides by the airbags (65) and (65) provided on the inner surfaces of the armrests (14) and (14) of the massage machine. FIG. 8 is a diagram illustrating a reset state of the massage machine, and FIG. 9 illustrates a use state.

A stretching method with the user's waist fixed will be described.
With the waist of the user fixed by the waist airbags (65) and (65), the seat (12) is reclined 25 to 35 ° from the reset state and then returned to the reset state. Repeat this.
Since the waist position does not shift, the waist is bent and stretched repeatedly, resulting in a waist stretching exercise.

In the above waist stretch method, when the seat (12) is reclined, the backrest (13) may also be reclined, that is, tilted backward.
In the reset state, the chair type massage machine (1) has the backrest (13) upright and the footrest (2) in a substantially vertical state with respect to the floor surface F. After getting up, the legs are in a state where the legs from the thighs to the toes are facing downward.
When the seat part (12) and the backrest part (13) are reclined, the upper body of the user is tilted backwards and the whole body is turned back. As a result, the user is particularly stretched by stretching the back muscles with his upper body bent backwards. At this time, if the waist is fixed to the armrests (14) and (14) with the waist airbags (65) and (65), the whole body can be stretched. If the heel and / or the tip of the foot of the user are fixed to the footrest (2), the stretch effect is further enhanced.

  Moreover, when the seat part (12) returns to the reset state, the backrest part (13) may be reclined backward and the footrest (2) may be reclined in a downward direction. In this case, the above-described stretching is performed also on the leg portion. If the leg is fixed to the footrest (2), a tensile force acts on the leg, so that the stretching effect on the whole body as well as the leg can be enhanced.

  Furthermore, a massage can be used in combination with the above-described stretching exercise by a massage device provided in the seat (12) or the backrest (13).
