DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below.
[0010]
The human body support means 3 that swings and pitches while supporting the human body is not particularly limited as long as it provides a relaxed feeling by pitching and swinging, but a simple bed type, a mat type, a chair type, and the like are conceivable.
[0011]
In the embodiment of FIG. 1, the human body support means 3 capable of giving the human body F reciprocal swing in the pitching direction is formed in a bed type, and the human body support means 3 mainly supports the upper body of the human body F. The upper body support part 1 and the lower body support part 2 that mainly support the lower body are formed. The lower body support portion 2 is fixed on the base plate 16, and the upper body support portion 1 is mounted on the base plate 16 so as to be rotatable in the vertical direction with the end on the lower body support portion 2 side as a rotation center. It is.
[0012]
A pair of suspending rods 19 whose upper ends are pivotally supported by a rotating shaft 18 are suspended from the base 4 installed on the floor surface 17, and are suspended from both side ends of the human body support means 3 in the substantially central portion in the longitudinal direction. By fixing the lower end portion of the lowering bar 19, the human body support means 3 is supported in a swingable manner in its longitudinal direction. The vibration means 5 includes a rod 20 that is actuated so as to perform a crank motion by a motor. The rod 20 is connected to the base plate 16 of the human body support means 3. As shown in 1 (a) and 1 (b), the body support means 3 is pitched and swung by operating the vibration means 5.
[0013]
In addition, an angle sensor 6 is provided in the lower body support portion 2 of the human body support means 3, and the swing angle of the lower body support portion 2 when the human body support means 3 is pitched and swung, that is, the lower body support portion 2 and the floor surface 17. The angle θ is measured. The angle sensor 6 is not particularly limited, but various displacement sensors can be used. Further, the upper body support portion 1 of the human body support means 3 is provided with a support angle control means 7 formed by using a spring, a plunger mechanism or the like, and the rising angle of the upper body support portion 1 from the base 4 is determined by this. It is controlled by the support angle control means 7. The support angle control means 7 is operated in conjunction with the pitching swing angle of the human body support means 3 measured by the angle sensor 6.
[0014]
In the relax device formed as described above, when the human body support means 3 is swung by operating the vibration means 5 with the human body F lying on the human body support means 3, the human body support means 3 And the pitching rocking | rocking of the same motion seeing from the base 4 can be given with respect to the human body F supported by the human body support means 3, and the human body F can be guide | induced to a relaxation state or a sleep state. Here, as the pitching swing angle increases forward (toe direction), the foot of the human body F becomes higher and the head becomes lower, and when the pitching swing angle exceeds a predetermined angle, as shown in FIG. The head of the human body F is below the toes with respect to the surface 17. At this time, the user looks like looking up at his / her foot from below, which may cause a sense of slipping backward (overhead direction). There is a high possibility of discomfort such as fear.
[0015]
Therefore, when the human body support means 3 is tilted and swung to the same angle as in FIG. 2, the angle of the upper body support portion 1 is adjusted by the support angle control means 7 so that the foot is viewed from the floor surface 17. Control is performed so that the tip does not become higher than the head. That is, when the swing angle of the lower body support portion 2 of the human body support means 3 measured by the angle sensor 6 becomes an angle at which the foot is higher than the head, the support angle control means 7 is operated in conjunction with this, As shown in FIG. 1B, the head is lifted upward by adjusting the rotation angle so as to raise the upper body support portion 1 so that the head does not become lower than the feet. The timing at which the angle of the lower body support portion 2 is changed by the support angle control means 7 may be changed gradually in conjunction with the swing angle detected by the angle sensor 6. The change may be started when the detected swing angle exceeds a predetermined value. Further, it may be determined in advance so that the angle adjustment by the support angle control means 7 is performed step by step corresponding to the swing angle detected by the angle sensor 6.
[0016]
However, the speed of the angle change of the human body support means 3 adjusted by the support angle control means 7 should not prevent the person sleeping on the human body support means 3 from relaxing. If the angle formed by the upper body support part 1 and the lower body support part 2 changes so much as to prevent the toes from being above the head, the human body F on the human body support means 3 is changed to the abdomen. Since the uncomfortable posture is burdensome and unpleasant feeling is strengthened, the range in which the angle between the upper body support portion 1 and the lower body support portion 2 is changed maintains a shape that can hold the human body F in an unreasonable posture. It is necessary to set the range.
[0017]
In the embodiment of FIG. 1, the support angle control means 7 is formed so as to adjust the angle between the upper body support section 1 and the lower body support section 2 by rotating the upper body support section 1 of the human body support means 3. However, you may form so that the lower body support part 2 may be rotated. Further, the support angle control means 7 may be formed so as to adjust the angle between the upper body support part 1 and the lower body support part 2 by deforming the upper surface of the upper body support part 1. For example, as shown in FIG. 3, an air bag is built in the upper surface portion of the upper body support portion 1, and the upper surface of the upper body support portion 1 is deformed by inflating the air bag so that the upper body of the human body F is raised and the head is raised. Can be kept below the feet.
[0018]
In the embodiment of FIGS. 4 and 5, the human body support means 3 is formed as a reclining chair that can give the human body F reciprocal swing in the pitching direction. The human body support means 3 is mainly composed of an upper body support portion 1 that supports the upper body of the human body F and a lower body support portion 2 that mainly supports the lower body. The lower body support portion 2 mainly includes the buttocks and thighs. It is formed of a seat portion 8 that supports and a footrest portion 9 that mainly supports the lower leg portion. The upper body support portion 1 is connected to one end of the seat portion 8 with a rotation shaft 21, and the footrest portion 9 is connected to the other end of the seat portion 8 with a rotation shaft 22 so as to be rotatable in the vertical direction. Each of the rotating shafts 21 and 22 is electrically driven. A supporting angle control means 7 is formed by the rotating shafts 21 and 22, and the upper body support portion 1 with respect to the seat portion 8. And the angle of the footrest portion 9 can be adjusted. In addition, an angle sensor 6 is provided at the seat 8 of the lower body support 2, and the swing angle of the seat 8 when the human body support means 3 is pivoted, that is, between the seat 8 and the floor surface 17. The angle is measured.

An armrest 33 is further provided on the backrest 32. Further, a mechanism for controlling the angle of the backrest portion 32 and footrest portion 9 of the upper body support portion 1 of the human body support means 3 with respect to the seat portion 8 by the support angle control means 7 and a mechanism for swinging the human body support means 3 are shown in FIG. And can be formed in the same manner as in FIG.
[0022]
And in the relaxation apparatus formed by such a reclining chair type human body support means 3, the human body support means 3 is operated by operating the vibration means 5 while the human body F is seated on the human body support means 3. By swinging, the human body F sitting on the human body support means 3 can be pitched and swinged, and the human body F can be led to a relaxed state or a sleep state. Here, as the pitching swing angle increases forward (toe direction), the toe of the human body F becomes higher and the head becomes lower, and when the pitching swing angle exceeds a predetermined angle θ, it is shown in FIG. In this way, the head of the human body F is below the toes with respect to the floor surface 17.
[0023]
Therefore, in the embodiment of FIG. 7, when the human body support means 3 is pitched and swung to the angle of FIG. 6B in this way, the support angle control means 7 uses the footrest part 9 of the lower body support part 2. By adjusting the angle, control is performed so that the toes do not rise above the head when viewed from the floor surface 17. That is, when the swing angle of the seat portion 8 of the lower body support portion 2 of the human body support means 3 measured by the angle sensor 6 becomes an angle at which the foot is higher than the head, the support angle control means 7 is interlocked with this. And the angle of the footrest 9 is adjusted so that the footrest 9 is rotated downward, so that the tip of the foot is directed downward, so that the head does not become lower than the foot. If the footrest portion 9 is thus rotated so that only the tip of the human body F is directed downward, the angle of the abdomen of the human body F on the human body support means 3 is not changed, and the human body F This prevents the posture from becoming an unreasonable posture that places a burden on the abdomen.
[0024]
In the embodiment of FIG. 8, the support angle control means 7 adjusts the angle of the upper body support portion 1 so that the foot tip does not rise above the head when viewed from the floor surface 17. I do it. That is, when the swing angle of the seat portion 8 of the lower body support portion 2 of the human body support means 3 measured by the angle sensor 6 becomes an angle at which the foot is higher than the head, the support angle control means 7 is interlocked with this. The head is lifted upward by adjusting the rotation angle so as to raise the upper body support portion 1 so that the head does not become lower than the feet. Further, in the embodiment of FIG. 9, an air bag is incorporated as the support angle control means 7 in the upper surface portion of the upper body support portion 1, and the upper surface of the upper body support portion 1 is deformed by inflating the air bag so that the human body F The upper body is raised so that the head does not fall below the feet. When the angle of the upper body support portion 1 is adjusted as described above, the angle of the seat portion 8 is adjusted to an angle at which the load on the abdomen of the human body F is not easily applied, or the angle of the armrest 33 is set at an angle at which the load on the elbow is not easily applied. The human body support means 3 can be adjusted to change the angle in order to hold the human body F in a comfortable posture even if it is not related to the height of the head and toes of the human body F. It is good to be able to do it.
[0025]
In the embodiment of FIG. 10, the support angle control means 7 adjusts the angle by which the upper body support portion 1 is rotated upward, and at the same time, the support angle control means 7 rotates the footrest portion 9 of the lower body support portion 2 downward. By adjusting the angle, control is performed so that the toes do not rise above the head when viewed from the floor surface 17. If the head of the human body F is lifted and the tip of the foot is lowered in this manner, the tip of the foot does not rise above the head even when the pitching swing angle of the human body support means 3 is further increased. Thus, the control can be easily performed.
[0026]
Further, as shown in FIG. 11A, when the pitching swing angle increases backward (overhead direction), the human body F is given a feeling of sliding forward (toes), but in this case, As shown in FIG. 11 (b), the upper body support portion 1 is moved downward by the support angle control means 7 in conjunction with the swing angle of the seat portion 8 of the lower body support portion 2 of the human body support means 3 measured by the angle sensor 6. At the same time as adjusting the angle of turning to the right, the angle of turning the footrest part 9 of the lower body support part 2 with the support angle control means 7 can be adjusted so as not to cause a feeling of sliding forward. It is.
[0027]
