Description

[Detailed description of the invention] The present invention relates to a bed relative refraction device.

Conventionally, a vent composed of one piece is the usual concept, but
This requires venting to obtain contact changes with the lying human body.

The present invention provides a bet that obtains the above-mentioned contact change, and will be described in detail in the following embodiments with reference to the drawings. 1st
One end of the pedestal leg 1 and the inner frame 2 in Figures 1 and 3 are pivotally connected (a) so that the inner frame 2 side is bent in one direction. The frame bodies 4 of the bed 3 to be hung are separated by being vertically cut through their central parts, and a connecting piece 5 is provided to connect the frame bodies 4 on both sides separated at the central part.
A pivot shaft 7, which has a long hole 6 provided inside and is pivotally attached to this in the vertical direction, is pivotally suspended from the connecting pieces 5 at both ends.

The bottle 8, which is movably fitted into the elongated hole 6, is provided at the end of the arm 10, which is passed through a worm wheel 9 which is pivoted to the pedestal 1 side. The worm boiler 9 meshes with an Ajz gear 18 which is provided at one end of the bed 8 and is connected via a transmission shaft 12 that communicates with the rotary handle 11. According to the configuration state G, the worm gear 13 and the worm wheel 9, which are engaged with each other by the rotation of the rotary handle 11, rotate the arm 10 in either direction, and the bin 8 is moved to either of the elongated holes 6 of the pivot shaft 7. The center portions of the frame bodies 4 on both sides, which are vertically separated and connected at the center portions, are held and bent in a manner such as “2d” and “e”. Therefore, depending on the refraction of the central portions of the frame bodies 4 of the belt 3, the human body f can be pulled down (e) and lifted up (d) from the horizontal position (g) on which it is placed.

The frame body 4 on both sides of the frame is supported by wheels 14 and supports 15 that are compatible with the inner frame 2.

As mentioned above, the frame 4 of the bed 3 is longitudinally cut through the center and connected to each other, and the longitudinal section is held by an arm lO or the like.
The posture of the human body f can be changed by moving up and down e, etc., and the back pressure on the bed 8 can be changed, thereby preventing bedsores and the like. The lifting (d) and lowering (e) movements described above can be continuously performed to improve the blood flow in the back, and can also be used for opening and closing the human chest. The actuation of the arm 10 of the present invention may be coupled to an electric mechanism.

Claims (1)

[Claims] The frame bodies on both sides are movably supported by pillars that are compatible with the inner frame of the bed, and the connecting pieces and pivots are attached to their relative parts! 1lII
The arm is connected by a long hole provided in the longitudinal direction of the axis between the two connecting pieces, and one is fitted with a pin provided at the end of the arm that is in axis communication with a worm wheel that engages with the ohm carrier. A relative refracting device in which the bottle moves through the elongated hole as the head rotates in either direction in the vertical direction, and the frame on the elongated hole side is bent up and down at the relative center G.
