MODE FOR EMBODYING THE INVENTION

[0054] Hereinafter will be described the present invention with reference to the attached drawings.

[0055] FIGS. 1 to 4 respectively show one embodiment of an oscillating sleep induction bed of the present invention, FIG. 1(a) being a vertical cross-sectional view in the short-length direction, FIG. 1(b) being a vertical cross-sectional view in the longitudinal direction, FIG. 2 being an exploded perspective view showing an oscillating support mechanism, FIG. 3 being a front view in the short-length direction of the oscillating support mechanism, and FIG. 4 being a front view in the longitudinal direction of the oscillating support mechanism.

[0056] An oscillating sleep induction bed 1 of the present invention has a bed body 1a and an oscillating support device 10 for supporting the bed body 1a in a manner allowing oscillation in the lateral direction of the bed. In this embodiment, the oscillating support device 10 is provided in four corner positions of the bed body 1a in total, so that four oscillating devices 10 are supposed to support the bed body 1a stably, while making it possible to oscillate the bed body 1a.

[0057] The oscillating support device 10 is provided with a support part 11 installed on the floor surface, a pendulum member 31 capable of oscillating in the lateral direction of the bed and a link member 21 that links an upper part of the support part 11 and a lower part of the pendulum member 31. In this embodiment, the link member 21 and the pendulum member 31 are installed at the front and rear sides of the support part 11 to increase the stability and also to keep the balance.

[0058] As to the link member 21 that links the upper part of the support part 11 and the lower part of the pendulum member 31, there are provided a plurality of spacedly arranged link members, more specifically, two link members respectively at the front and rear sides of the support part according to this embodiment, and both ends of each link member 21 are in the form of pin joint structure.

[0059] In this embodiment, the support part 11 is formed in the shape of a rectangular parallelepiped support frame body composed of a pair of lower horizontal materials 12 extending in the direction of oscillation, another pair of lower horizontal materials 13 extending in a direction orthogonal to the direction of oscillation and connecting the lower horizontal materials 12 in the direction of oscillation together, four columnar materials 14 uprightly installed on the lower horizontal materials 12 in the direction of oscillation, a pair of upper horizontal materials 15 extending in the direction of oscillation and installed on the upper surface of the columnar materials 14 and another pair of upper horizontal materials 16 extending in a direction orthogonal to the direction of oscillation and connecting the pair upper horizonal materials 15 in the direction of oscillation together.

[0060] With the pendulum member 31 subjected to pin joint to the upper part of the support part 11 constituting the rectangular parallelepiped support frame body, the upper end part of the pendulum member 31 is fixed to the lower surface side of the bed body 1a. By so doing, the pendulum member 31 oscillates with respect to the support part 11, whereby the bed body 1a oscillates in the lateral direction.

[0061] In this embodiment, as shown in FIG. 1., a drive device 40 is provided between the bed body 1a and the upper part of the support part 11 constituting the oscillating support device 10, whereby the bed body 1a supported oscillatably through the link member 21 and the pendulum member 31 is made to oscillate laterally with respect to the support part 11. As the drive device 40, use can be made of a linear servo motor, for instance.

[0062] As to the amplitude D (half amplitude) in the reciprocating motion at the time when the bed body 1a is subjected to oscillation by the drive device 40, amplitude adjustment is performed such that this amplitude D can be set to at most about 10 cm, preferably, a value about within the range of 1.5 cm≤D≤8 cm. Likewise, as to the vibration frequency f in the reciprocating motion of the bed body, vibration frequency adjustment is performed such that this vibration frequency f can be set to at most about 0.8 Hz, preferably, a value about within the range of 0.1 Hz≤f≤0.7 Hz.

[0063] The drive device 40 is operated to oscillate the bed body 40, and as a result, the user S lying on the bed can be efficiently induced to sleep under the control of the drive device.
