DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
[0010]
FIG. 1 is a side view of a state in which the head support plate of the bed according to the present invention is raised, and FIG. 2 is a state in which both the head support plate and the back support plate of the bed according to the present invention are raised. 3 is a side view of the bed according to the present invention, and FIG. 4 is an explanatory view showing the function of the bed of the present invention. FIG. It is explanatory drawing showing the function.
[0011]
As shown in FIGS. 1 to 3, the bed according to the present invention includes a bed frame body 1, a floor plate 2 arranged on the frame body 1, and a telescopic actuator 3 for raising and lowering the floor plate 2. In general, a mattress 4 is placed on the floor board 2, and a lying person 5 who needs nursing or care, such as a patient, a bedridden elderly person, etc., goes to bed on the mattress 4.
[0012]
The floor plate 2 is divided into five parts: a head pad 6, a back pad 7, a buttocks pad 8, an upper leg pad 9, and a lower leg pad 10, for example, hinges 11, 12, 13, 14 are configured to be foldable and connected at end portions adjacent to each other.
[0013]
The actuator 3 is, for example, a telescopic hydraulic cylinder, and is arranged with one end 3 a fixed to the back surface of the head pad 6 and the other end 3 b fixed to the bed frame 1 so as to be rotatable.
[0014]
The back pad 7 is connected to the bed frame 1 via a link A 15 in the vicinity of the side adjacent to the buttocks 8. At this time, the link A15 is connected, of course, so as to be rotatable.
[0015]
The buttocks support plate 8 is connected to the substantially central portion of the link A15 via a bracket 16 in the vicinity of the side adjacent to the back support plate 7 and in the vicinity of the side adjacent to the upper leg support plate 9 or the upper leg support. The connecting portion with the plate 9 is connected to the bed frame 1 via a link B17. The connection of the link B17 is also rotatable. 18 is a stay, 19 is a stopper.
[0016]
In the operation of the bed according to the present invention having the above-described configuration, as shown in FIG. 1, when the cylinder portion of the actuator 3 is first extended, the force of the actuator 3 acts in the direction of the arrow, thereby fixing to the bed body 1. The other end 3b thus rotated rotates to raise the head rest plate 6 in the direction of the arrow.
[0017]
Further, as shown in FIG. 2, when the actuator 3 is further extended, the head pad 6 rises further in the direction of the arrow, but due to the action of the stopper 19, the head pad 6 rises to a specific position. In place of this, the back pad 7 starts to rise.
[0018]
Furthermore, as shown in FIG. 3, when the actuator 3 is further extended, the head pad 6 and the back pad 7 further rise in the direction of the arrow while keeping the angle formed between them constant, Eventually, the lying person 5 on the mattress 4 raises the upper body completely. The position states of the head pad 6 and the back pad 7 at this time are shown in FIG.
[0019]

As shown in FIG. 4, the horizontal position drawn by the solid line changes to the inclined position drawn by the broken line.
[0020]
Further, at this time, the connecting portion of the upper leg portion abutting plate 9 and the lower leg portion abutting plate 10 is raised in a mountain shape as shown in FIGS.
[0021]
As a result, as shown in FIG. 3, the recumbent person 5 on the mat 4 has its upper body fully raised, and the buttocks support plate 9 is slightly inclined in the buttocks direction, so that the buttocks are prevented from slipping forward. In addition, the leg portion is lifted upward by the rise of the connecting portion formed by the upper leg portion abutting plate 9 and the lower leg portion abutting plate 10, and can be comfortably raised on the bed.
[0022]
The bulge of the connecting portion is formed by being pulled by the operation of the ring B17. Further, although not shown, it can also be formed by separately pushing up another actuator.
[0023]
Further, by contracting the above-described actuator 3, contrary to the above-described operation, the head pad 6 and the back pad 7 are brought down, the buttocks pad 8 is returned horizontally, and the upper leg pad 9 The floor plate 2 can be tilted horizontally with the bulge formed by the lower leg plate 10 being lowered, and the standing recumbent person 5 can be returned to its original state.
[0024]
【The invention's effect】
The above-described present invention has the following effects.
(1) As shown in FIG. 1, first, only the head pad 6 rises slightly, so that the lying person 5 on the mattress 4 is raised and the anxiety is resolved.
[0025]
(2) Next, as shown in FIG. 2 and FIG. 3, while keeping the angles of the head pad 6 and the back pad 7 constant, these are further raised to raise the upper body of the lying person 5. At this time, since the buttock pad 9 is tilted so that the buttock direction is lowered while being pulled in the buttock direction of the lying person 5, the lying person 5 does not fall off the buttock pad 9.
[0026]
(3) Furthermore, since the connecting portion of the upper leg pad 9 and the lower leg pad 10 is pulled up by the link B17, the lying person 5 can lift the leg on the bed when getting up. Because of this, you can get up comfortably on the bed.
[0027]
