Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a wake-up type bed device.
[0002]
[Prior art]
Conventionally, a first floor plate, a second floor plate, a third floor plate, and a fourth floor plate supporting a user's back, buttocks, thighs, and legs, respectively, are provided on a frame, and the first floor plate stands on the head side. In the wake-up type bed apparatus in which the leg side of the third floor panel rises in conjunction with the third floor panel, when the first floor panel rises to a predetermined angle (75 degrees), the third floor panel prevents the user from pressing the abdomen. The floorboard descends and shifts to a horizontal position (for example, see Patent Document 1).

[0004]
[Problems to be solved by the present invention]
However, in the above-described wake-up bed device, when the erection angle of the first floor plate reaches a predetermined value (75 degrees), the third floor plate moves down and shifts to a horizontal position, so that the lower body of the user shifts in the direction of the toes. There was a defect.
[0005]
Therefore, it is a technical object of the present invention to provide a wake-up type bed apparatus free of the above-mentioned problems.
[0006]
[Means for Solving the Problems]
The technical measures taken to solve the above-mentioned problems include a first floor plate, a second floor plate, a third floor plate, and a fourth floor plate that respectively support the back, buttocks, thighs, and legs of the user on a frame. In a rising bed apparatus in which the leg side of the third floor panel is raised in conjunction with the rising of the head side of the first floor panel, when the rising angle of the first floor panel becomes a predetermined value, The third floor plate is lowered so as not to be parallel to the floor surface, and the head side of the frame is raised from the floor surface.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0008]
A rectangular frame is formed from the opposing bedboard 1, footboard 2, and main frames 3a and 3b, and first to fourth floor plates 4, 5, 6, and 7 are provided in the frame, and the main frame is formed. A horizontal rod 8 and a rotating shaft 9 are installed between 3a and 3b, and first to third support members 10, 10, 11, 11, 12, and 12 are sequentially fixed to both side walls of the main frames 3a and 3b. . The first to fourth floor plates are pivotally connected by first to third hinge members 13, 13, 14, 14, 15, 15, respectively, and the first floor plate 4 and the third to fourth floor plates 6, 7 are rotatable. The second floor plate 5 is fixed to the first supporting members 10. The lower peripheral edge of the first floor panel 4 on the side of the bed board 1 is engaged with the horizontal rod 8, and a support arm 16 is provided on the lower peripheral side of the first hinge member 13, 13 side of the floor panel 4. A drive shaft 17 is provided on the motor 16 (not shown) so as to be able to move forward and backward, and the first floor plate 4 is formed via a support arm 16 so as to be able to move up and down. A cam member 18 having a shape shown in the figure is provided around the lower surface of the third floor plate 6 on the side of the third hinge members 15, 15, and a rotating arm 20 provided with a roller 19 that engages with the cam member 18 below the rotating arm 20. 9, the supporting arm 16 and the rotating arm 20 are rotatably connected to a connecting rod 21. When the drive shaft 17 advances and retreats, the supporting arm 16 rotates and the rotating arm is connected via the connecting rod 21. 20 is formed to rotate. Wheels 22, 22 are provided on the periphery of the lower surface of the fourth floor panel 7 on the footboard 2 side, and the wheels 22, 22 are mounted on the third support members 12, 12 and are capable of moving forward and backward.
[0009]
A caster 50 is mounted on the foot board 2. The headboard 1 is supported by a lifting actuator 52.
[0010]
When the drive shaft 17 moves forward (screws leftward in FIG. 1) from the state shown in FIG. 1, the connecting rod 21 and the wheels 22, 22 move forward, and the support arm 16 and the rotary arm 20 rotate, and the roller 19 moves forward along the cam member 18, the first floor plate 4 is raised and lowered, and the third and fourth floor plates 6 and 7 are bent upward (FIG. 2). When the drive shaft 17 moves forward, as shown in FIG. 3, the first floor plate 4 has a maximum undulation angle of 45 degrees and the third floor plate 6 has a maximum undulation angle of about 10 degrees. Further, when the drive shaft 17 moves forward and the undulation angle of the first floor plate 4 becomes about 75 degrees, as shown in FIG. 4, the drive shaft 17 stops (the undulation angle of the first floor plate 4 becomes about 75 degrees). ), The undulation angle of the third floor plate 6 is reduced by about a predetermined value from about 10 degrees to a limit not to be horizontal, and the lifting actuator 52 raises the headboard 1 by a predetermined height. Thus, the rise in the predetermined height of the headboard 1 is limited by the angle (5 to 12 degrees) formed by the main frame 3a with respect to the floor.
[0011]
【The invention's effect】
According to the present invention, a first floor plate, a second floor plate, a third floor plate, and a fourth floor plate that respectively support a user's back, buttocks, thighs, and legs are provided on a frame, and the head of the first floor plate is provided. In the wake-up type bed device in which the leg side of the third floor plate is erected in conjunction with the erection of the floor portion, when the erection angle of the first floor plate becomes a predetermined value, the third floor plate becomes parallel to the floor surface. Since the head side of the frame is lifted from the floor surface while being lowered to the extent that it does not become a limit, when the rising angle of the first floor plate reaches a predetermined value, prevention of compression of the thighs and stability of the body The compatibility can be achieved, and a great effect is obtained in practical use.
