BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swing bed capable of vertically swinging left and right side portions or head legs.

[0002]

2. Description of the Related Art Conventionally, a cradle has been known as a bed or other bedding that can swing a sleeping person. In the cradle, legs having curved edges projecting downward at the center of the floor-contacting surface were provided between the heads of the bed sides so that the head and the feet were alternately moved up and down. Therefore, the cradles remain stationary unless they are touched by the hands, but when the sleeper moves when he or she rolls over, the rocking motion occurs regardless of whether the sleeper likes it or not I hated that I couldn't maintain my condition.

SUMMARY OF THE INVENTION In view of the above points, the present invention has an object to obtain a bed capable of selecting a swingable state and a fixed state.

[0004]

Means for Solving the Problems An elevating device is interposed between a first frame on which bedding such as a mattress is placed, and a second frame provided below the first frame. Arc-shaped legs projecting downward, and fixed legs that can support the second frame in a stationary state are provided on the second frame, and when the first and second frames approach each other, the arc-shaped legs are on the floor from the fixed legs. Project toward the surface.

[0005]

When the bed according to the present invention is used in a fixed state, the raising / lowering device on the second frame is actuated and the first frame is raised by the raising / lowering device. When the legs of the first frame separate from the floor surface due to the rise of the first frame, the legs of the second frame come into contact with the floor surface instead of the legs of the first frame.
Since the fixed legs of the second frame are provided at the four corners of the frame, for example, it is possible to support the second frame in a stationary state.

When it is desired to use the bed of the present invention in a swing state, conversely to the above, the lifting device is operated, and when the first frame is lowered, the legs of the first frame come into contact with the floor, and the lifting device is operated as it is. And the second frame is the first
Closer to the frame, the legs of the second frame will be spaced from and on the floor. In this state, the leg of the second frame has a downwardly convex arc surface. Therefore, when a vertical force is applied to the edge of the bed, the second frame swings according to the arc surface. Become.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An example of the bed 100 of the present invention will be described below with reference to the drawings. The illustrated example is a bed in which the left and right sides of the bed can be swung up and down.

The bed 100 of the present invention has a first frame 2 and a second frame 3 on which the bedding 1 such as a mattress is placed, and the lifting and lowering device 4 mounted on the second frame 3 supports the first frame. . The lifting device 4 is configured as follows. On the parallel side frames 5 and 6 of the second frame 3, guide rails 7 and 8 having a U-shaped cross section are provided, respectively. Similarly, guide rails 9 and 10 are provided on the lower surface of the first frame 2 at the same intervals as the guide rails 7 and 8 by appropriate means.

Numerals 11 and 12 are X-arms pivotally supported by a shaft 13 so that the crossing angle can be changed, and rolls 14 and 15 respectively provided at the ends are provided with a guide rail 9 of the first frame and a guide rail of the second frame. 7 and 7 are rotatably fitted together. The other ends 16 and 17 of the X-shaped arms 11 and 12 are fixed to the guide rails 7 and 9, respectively. Also,
X-shaped arms 19 and 20 pivotally supported by a shaft 18 are also provided between the guide rails 8 and 10, and rolls 21 and 22 provided at one end of each X-shaped arm 19 and 20 can be freely rolled on the guide rails 8 and 10. Is fitted to. And, the other end has guide rails 8 and 10.
It is fixedly supported by. A beam 23 is provided between the X-shaped arms 12 and 19, and an arm 24 is projected. Second
The frame 3 is provided with a rod 25 which supports the motor M and which is projected or retracted by the rotation of the motor M.
Connect to.

Arc-shaped legs 27, 28 each having an arc-shaped floor contact surface 26 are provided in the width direction of the bed 1 at the head position and the leg position of the first frame 2. The arc-shaped floor contact surface 26 defines the arc-shaped floor contact surface 26 that protrudes most downward in the widthwise center line L of the bed 1. The example shown is arcuate legs 27, 28.
Although a pipe-shaped member is bent to fix the base portion to the first frame 2, a plate-shaped member may be used. In addition, in the lower four corners of the second frame 3, the fixed legs 29, 3
0, 31, 32 (31 is not shown) are provided. The arcuate legs 27, 28 have such a height that they can contact the floor surface instead of the fixed legs 29, 30, 31, 32 when the first frame 2 and the second frame 3 approach each other.

In the above embodiment, the arcuate legs 27, 28 are provided.
The arcuate legs 27, 28 are provided one on each side of the bed frame 2 in the length direction of the bed frame, that is, from the head to the leg direction. Of course, the same swing can be used.

Next, the operation of the bed of the present invention will be described.

The state shown in FIG. 1 shows a state in which the elevating / lowering device 4 is contracted most and the first frame 2 and the second frame 3 are close to each other. At this time, the fixed leg 2 of the second frame 3
Floor contact surface 33 of 9, 30, 31, 32 (31 is not shown)
Is located higher than the most projecting portion of the center of the floor-contacting surface 26 of the arcuate legs 27, 28, and the bed 1 is supported by the arcuate legs 27, 28. Therefore, the bed 1 swings when a vertical force is applied to its side portion.

The bed 1 is fixed as follows. The lifting / lowering device 4 is operated from the state shown in FIG. That is, the motor M is operated, the rod 25 is projected, and the arm 24 is moved through the beam 23 so that the rolls 14, 15 and 21, 22 of the X-arms 11, 12 and 19, 20 are guided by the guide rails 7, 9 and 8 in FIG. Move to the right within 10 and move to X arm 1
Open 1,12 and 19,20. As a result, the second frame 3 descends, the floor contact surfaces 33 of the fixed legs 29 to 32 come into contact with the floor, and when the motor M continues to rotate, the second frame 3 descends further and the arcuate legs 27 of the first frame 2 continue. , 28 are separated from the floor surface 26, and the bed 1 is supported by the fixed legs 29 to 32, so that the bed 1 is immobile.

[0015]

In the bed 1 of the present invention, an elevating device is interposed between a first frame on which bedding such as a mattress is placed and a second frame provided below the first frame. The arc-shaped leg with the floor protruding downward is
The frame is provided with fixed legs that can support the second frame in an immovable state, and when the first and second frames approach each other,
Since the arcuate leg is directed toward the floor surface from the fixed leg and protrudes, the fixed state and the swinging state can be easily changed only by taking the leg in and out.
