Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to an improvement of a bed apparatus, more specifically to an improvement of a wake-up bed apparatus, a hospital treatment bed, Used for home reclining, etc.

(Prior Art) As a conventional wake-up type bed device, as described in Japanese Utility Model Publication 57-4558.
There is one as shown in Japanese Patent Publication No. 84, which has first to fourth floor plates connected from the head toward the legs, and the first floor plate on the head side is the fixed second floor plate. Rotatably, the third floor plate is also rotatably pivoted on the second floor plate, and the fourth floor plate is rotatably pivoted on the third floor plate. In addition, the first floor plate is connected to the third floor by the link mechanism.
When the first floor body is undulated in cooperation with the floor plate of No. 3, the third floor plate is also undulated, and the third to fourth floor plates are formed to be bent upward.

(Problems to be solved by the invention) In the conventional bed apparatus, when the undulating angle of the first floor plate on the head side becomes about 75 degrees, the back of the user and the legs are bent at a substantially right angle. The person felt very oppressive and distressed. Therefore, the present invention has been made to solve such a problem, and the undulation angle of the first floor plate on the head side is about 7 mm.
It is a technical issue to make it possible for the user to comfortably use the product even if it reaches 5 degrees without feeling pressure.

[Constitution of device]

(Means for Solving the Problems) The technical means of the present invention is to provide a support arm on the first floor plate on the head side, provide a cam member on the third floor plate, and engage the cam member below the cam member. Providing a rotating arm with matching rollers,
That is, the supporting arm and the rotating arm are connected by a connecting rod.

(Operation) When the first floor plate is undulated, the roller advances along the cam member and the third to fourth floor plates bend upward. Further, when the first floor plate continues to undulate and is interlocked with the maximum undulation angle, the roller engages with the third floor plate, and the third to fourth floor plates fall horizontally and the second to second floor plates fall.
4 Floorboard is held horizontally.

(Embodiment) FIGS. 1 to 4 show an embodiment of a bed apparatus according to the present invention, in which a rectangular frame body is formed from a bed board 1, a foot board 2 and main frames 3a and 3b which face each other, and The first to fourth floor plates 4, 5, 6, 7 are arranged in the main frame 3a, 3b, and the horizontal rod 8 and the rotary shaft 9 are installed between the main frames 3a, 3b. The receivers 10, 10, 11, 11, 12, 12 of 1 to 3 are sequentially fixed. The first to fourth floor plates are pivoted by the 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 provided.
Is rotatably formed, and the second floor plate 5 is the first receiving member 1
It is fixed to 0 and 10. The lower edge of the first floor plate 4 on the bedboard 1 side engages with the horizontal rod 8, and a support arm 16 is provided on the lower surface circumference of the first hinge plate 13 on the first hinge member 13 side. 16 has a drive shaft 17 that can move forward and backward
Is provided, and the first floor plate 4 is formed so as to be able to rise and fall via the support arm 16. A semi-disc shaped cam member 18 is provided on the lower surface peripheral edge of the third floor plate 6 on the third hinge member 15, 15 side.
Is provided, and a rotating arm 20 provided with a roller 19 which engages with the cam member 18 is pivotally provided on the rotating shaft 9 below, and the supporting arm 16 and the rotating arm 20 are rotatably connected to the connecting rod 21. When the drive shaft 17 moves forward and backward, the support arm 16 rotates, and the rotary arm 20 rotates via the connecting rod 21. Wheels 22, 22 are provided on the lower surface peripheral edge of the fourth floor plate 7 on the footboard 2 side.
2, 22 are placed on the third receiving members 12, 12 and can move forward and backward.

When the drive shaft 17 moves forward, the connecting rod 21 and the wheels 22,
22 moves forward, the support arm 16 and the rotary arm 20 rotate, the roller 19 moves forward along the cam member 18, the first floor plate 4 undulates, and the third to fourth floor plates 6 and 7 move. Bend upwards. Further, when the drive shaft 17 moves forward and the undulation angle becomes about 75 degrees, the roller 19 engages with the third floor plate 6, and the third to fourth floor plates 6 and 7 fall horizontally to the second to fourth floor plates.
The floor boards 5, 6, and 7 are held horizontally. After that, when the drive shaft 17 retreats, the roller 19 retreats along the cam member 18, the first floor plate 4 falls, and the third to fourth parts are laid down.
When the floor plates 6 and 7 of No. 3 are bent upward and the drive shaft 17 is further retracted, the 3rd to 4th floor plates 6 and 7 lie down horizontally,
The fourth floor plates 4, 5, 6, 7 are held horizontally. In this embodiment, the undulation angle of the first floor board 4 is 45 degrees, the undulation angle of the third floor board 6 is maximum at about 10 degrees, and the final undulation angle of the first floor board 4 is about 75 degrees, and the third to the fourth floors. The floor boards 6 and 7 become substantially horizontal. In addition, by changing the shape of the cam member 18,
The refraction of the floor plates 6 and 7 of No. 4 changes.

Another embodiment is shown in FIG. 5, in which a roller 19 is provided at the end of the connecting rod 21 and a rail 23 which engages with the roller 19 is provided below, and the rest is formed in the same manner as the above embodiment. The same operation as that of the above-described embodiment is achieved.

[Effect of device]

According to the present invention, when the head-side floor plate starts to undulate, the leg-side floor plate also undulates to prevent the user's body from moving, and when the final undulation angle is reached, the leg-side floor plate lays down horizontally for use. Eliminates the oppressive feeling of the person.
