It is installed. Therefore, this upper body support part 28 can be used as an armrest, especially when using as a chair, as shown in FIG. 2, On the other hand, when preventing or treating a back pain, as shown in FIG. The elbow or flank of 1) is contacted from below, and the upper body 5 of the human body 1 is supported from below, and the weight of the upper body 5 is taken in. Thereby, instead of the lower body 6 of the human body 1, the weight of the upper body 5 can be supported and the lower body 6 can be released from the weight of the upper body 5.

In addition, in order to reliably support the weight of the upper body 5 including the head part 4 in this way, a metal core material is used for this upper body support part, and this is coat | covered with materials, such as a urethane which has cushion characteristics, Moreover, it is preferable to coat and form the surface with a textile material. In addition, it is preferable to install a detachable belt (not shown) on the front surface of the upper body support 28 so that the human body 1 does not deviate forward than the upper body support 28.

On the other hand, as shown in FIGS. 1 and 3, the seat surface portion 14 has the rear end portion 14A of the backrest portion 12 displaced downward (refer to the arrow X in FIG. 1), and the upper body support portion ( The human body 1 is separated from at least a part of the thigh part 3 of the human body 1 supported by the upper body 5 by 28, while at the front end part 14B opposite to the backrest part 12 side. A part of the leg part 7 of) is supported. Thereby, especially as shown in FIG. 3, the health device 10 of this invention uses the upper body support part 28 and the front end part 14B of the seat surface part 14 displaced downward as a point. ), The waist 8 can be made to float. For this reason, the health device 10 of the present invention releases the waist 8 from the gravity of the upper body 5 while installing the chair as a furniture without discomfort in the home and the like, and by the weight of the lower body 6 itself. The spine can be naturally stretched to prevent or treat low back pain very effectively (see arrows in FIG. 3).

In the present invention, as shown in Figs. 1 and 3, the front end portion 14B of the seat surface portion 14 is used as a chair when the rear end portion 14A of the seat surface portion 14 is displaced downward. It is set so that a part of leg part 7 may be supported so that it may displace | deviate upward from the position in (refer to arrow Y of FIG. 1). For this reason, the front end part 14B of the seat surface part 14 which is the support point of the leg part 7 is set to a high position, and can support the waist part 8 which floated in the air from a high position, It is easy to open a waist, and it does not apply an excessive burden to a posture of a user, and can treat or prevent low back pain smoothly.

Similarly, in the present invention, as shown in FIGS. 1 and 3, the front end portion 14B of the seat surface portion 14 serving as the support point of the human body 1 is the rear end portion of the seat surface portion 14. When 14A is displaced downward, it is displaced forward than the position at the time of use as a chair (refer to arrow Y in FIG. 1), and it is set so that a part of leg part 7 may be supported. Thereby, as shown in FIG. 3, as a result of the waist 8 falling down, it supports the knee part (boundary of the thigh part 3 and the calf part 9) which tends to slip forward naturally. Since the front end part 14B of the seat surface part 14 supports the thigh part 3 by a middle part, it does not apply a burden to the thigh part 3, and the user forces the unreasonable posture. It is possible to maintain the state of floating the waist portion 8 naturally because it is not affected, so that the treatment or prevention of low back pain can be performed smoothly.

The displacement of these seat surface portions 14 below [1] rear end 14A, [2] upward of front end 14B, and [3] forward of front end 14B are Although there is no restriction | limiting in particular in the specific embodiment which achieves these, Specifically, it can achieve using the following link mechanism 30. As shown in FIG.

That is, the seat surface portion 14 is supported by a link mechanism 30 having a first swing arm 30A provided on the rear end 14A side and a second swing arm 30B provided on the front end 14B side. have. As shown in Figs. 1 to 4, these rocking arms 30A and 30B are swingably attached to the base frame 16 via a rocking shaft, while the upper end is the rear surface of the seat surface portion 14. Is attached so as to be able to swing through a swing shaft. Therefore, the seat surface portion 14 is supported on the base frame 16 as shown in Figs. 1 to 3, and these first and second swing arms 30A and 30B are seat surface portion 14. By swinging toward the front end portion 14B of (see arrows A and B in FIG. 1), the rear end portion 14A can be displaced downward (see arrow X in FIG. 1).

In this case, as shown in FIGS. 1 and 3, the first swing arm 30A toward the rear end 14A is slightly toward the front end 14B between the base frame 16 and the seat surface 14. It is installed at an angle (see (θ1) in FIG. 1) and is attached to a position slightly closer to the front end portion 14B than the rear end portion 14A of the seat surface portion 14. Therefore, this 1st swinging arm is arrange | positioned substantially in line with the seat surface part 14, when the rear end part 14A of the seat surface part 14 is displaced downward, as shown to FIG. 1 and FIG. While displacing the rear end portion 14A downward to the position, the rear end portion 14A is in contact with the rear surface of the seat surface portion 14 in that state, while supporting the seat surface portion 14, and further downward of the rear end portion 14A. Displacement can be suppressed. In addition, although the inclination angle (refer to ((theta) 1) of FIG. 1) of this 1st oscillation arm 30A depends also on the length of the said oscillation arm 30A, etc., it is preferable to set it to about 15 degrees, for example.

On the other hand, as shown in Figs. 1 and 3, the second swing arm 30B on the front end portion 14B is perpendicular to the base frame 16 and the seat surface portion 14 so as to be perpendicular to these. At the same time, the position of the rear end portion 14A side of the seat surface portion 14 rather than the front end portion 14B, more specifically, when seated on the seat surface portion 14 as shown in Fig. 3 It is attached to the back surface of the seat surface part 14 in the place corresponded to the substantially center vicinity of the part 3.

Therefore, this second swing arm 30B reliably supports the load applied to the seat surface portion 14 when used as a chair, while the rear end 14A of the seat surface portion 14 is displaced downward. By making the swing axis 30b of the second swing arm 30B on the rear surface of the seat surface portion 14 as a point, the front end portion 14B of the seat surface portion 14 can be displaced upwards than when used as a chair. have.

In addition, the second swing arm 30B is inclined forward with the first swing arm 30A in response to the swing toward the front end portion 14B of the first swing arm 30A, and thus, the front end portion 14B. Can be displaced forward from the position at the time of using as a chair. In this case, as shown in FIGS. 1 and 3, the second swing arm 30B has a seat surface portion 14 more than the distance between the first swing arm 30A on the base frame 16. 1 and FIG. 1 and FIG. 1 because the distance between the first swinging arm 30A on the back surface of the upper side is shorter, and as a result, the displacement amount of the second swinging arm 30B is smaller than that of the first swinging arm. As shown in Fig. 3, even if the first swinging arm 30A on the rear end 14A side is inclined toward the maximum amount and disposed substantially in a straight line with the seat surface portion 14, the second swinging arm 30B is there. The seat surface portion 14 can be supported while the inclined angle is given to the seat surface portion 14 without being inclined until it can be maintained. Therefore, by adjusting the attachment position, the inclination angle, the length, and the like of these rocking arms 30A and 30B, the rear end portion 14A of the seat surface portion 14 is displaced downward with respect to the base frame 16. Inclination angle etc. can be set suitably.

As shown in Figs. 1 to 4, the link mechanism 30 further includes an actuator 32 connected to the first swing arm 30A on the rear end 14A side. The actuator 32 supports the first swinging arm 30A from being unintentionally displaced from a predetermined position, and contracts the first swinging arm 30A toward the front end 14B of the seat surface 14. While rocking, the first rocking arm 30A can be rocked toward the back 12 by stretching. Since the second swing arm 30B is connected to the first swing arm 30A via the base frame 16 and the seat surface portion 14, the second swing arm 30B interlocks with the swing of the first swing arm 30A. You can swing.

The actuator 32 can be operated by a controller (not shown) electrically connected to the actuator 32. The seat surface portion 14 is turned on by switching the actuator 32 on and off. The seating position (approximately when using as a chair: but not necessarily horizontally, may be slightly inclined in order to ensure comfortable stability) and the seat surface part 14 shown in FIG. The rear end 14A of the can be switched to a position displaced downward (when preventing or treating back pain). Moreover, it is also possible to set it as the setting which can adjust the displacement amount of this actuator 32, and can arbitrarily adjust the displacement amount of 14 A of rear end parts of the seat surface part 14 arbitrarily.

The operation of the swinging arms 30A, 30B by this actuator 32 is advantageous in that the user can handle the health appliance 10 by simple operation, but swings the swinging arms 30A, 30B. There is no restriction | limiting in particular in the power to make, and unlike the Example shown, otherwise, for example, the rocking lever which is not shown to the 1st rocking arm 30A is connected, and this rocking lever is a front end part of the seat surface part 14, for example. The first swing arm 30A swings toward the front end portion 14B of the seat surface portion 14 by being pushed toward the side 14B, while the first swing arm 30A is turned back toward the backrest portion 12. It may be made to swing to the back part. In this case, the swing lever may be operated by the user himself or by mechanical operation.

Moreover, as shown in FIG. 4, these rocking arms 30A and 30B can support the seat surface part 14 reliably so that at least the 2nd rocking arm 30B of the seat surface part 14 may be carried out. Near the left and right ends, the first swing arm 30A connected to the actuator 32 is provided near the center of the seat surface portion 14, and the left and right sides of the seat surface portion 14 are located above the actuator 32. It can be installed to extend near the end, and can be attached to the seat surface portion 14. However, as long as the installation number, installation place, and shape of these rocking arms 30A, 30B, and the actuator 32 can reliably support the seat surface part 14, there will be no limitation in particular, For example, Unlike the illustrated embodiment in which the second swing arm 30B is provided at the left and right ends of the seat surface portion 14, and the first swing arm 30A is located near the center of the seat surface portion 14, the first swing arm 30A is provided. ) May be provided near the left and right ends of the left asbestos portion 14, and the second swing arm 30B may be provided near the center of the seat surface portion 14, and three places may be located near the left and right ends of the seat surface portion 14 and the center thereof. WHEREIN: The 1st and 2nd swinging arms 30A and 30B can also be provided, respectively. In this case, a power source can also be set for each pair of the angular swinging arms 30A and 30B. For example, one of the swinging arms 30A and 30B can be set to either the central link mechanism 30 or the like. The power source may be installed only in the case of) and the other swinging arm may be interlocked.

Moreover, there is no restriction | limiting in particular in the specific form of displacing the seat surface part 14 including the power source, the whole link mechanism 30, and if the displacement of the said seat surface part 14 can be ensured, another It is also possible to form. As an example, for example, in the illustrated embodiment, the actuator 32 is connected to the first swinging arm 30A. However, the actuator 32 is disposed from the rear side of the health apparatus 10 toward the front side, and thus the seat surface portion. It may be connected to the second swinging arm 30B on the front end portion 14B side of (14). In any case, in the present invention, only a relatively simple configuration such as the swinging arms 30A and 30B and the power source can obtain a high prevention or treatment effect of low back pain. Can be used.

In addition, in this invention, it is preferable to provide the ottoman part 34 provided so that it may be bent and extended from the front end part 14B of the seat surface part 14, as shown to FIG. As shown in FIGS. 2 and 3, the ottoman portion 34 can support the calf portion 9 of the human body 1, and therefore, of course, in particular, when used as the ordinary chair shown in FIG. 2, Even in the prevention or treatment of low back pain shown in FIG. 3, the user can leave the weight of the calf part 9 to the ottoman part 34 so that the lower back posture can be maintained comfortably, thereby treating or preventing low back pain. It can be performed smoothly.

In addition, this ottoman part 34 is integrally formed with the seat surface part 14 in the Example shown, Therefore, as shown to FIG. 1 and FIG. 3, the rear end part 14A of the seat surface part 14 is shown. In response to the downward displacement of the, the ottoman portion 34 is displaced upward. However, unlike the embodiment shown in the figure, the ottoman portion 34 is pivotably connected to the seat surface portion 14 so that the inclination angle between the seat surface portion 14 and the seat surface portion 14 can be adjusted to an angle at which the user feels comfortable. It is also possible to set.
