and an air supply device 5 for controlling the operation of the above-mentioned actuating device.

The bed main body 2 has legs 21a below the four corners.
a fixing bed 21 formed in the shape of a substantially rectangular frame integrally erected; and a substantially rectangular fitting recess 2 recessed in the upper surface of one longitudinal end of the fixing bed 21.
The fixed bed 2 is fitted to the fixed bed 1b and is arranged so as to be able to raise the upper body of a doll lying on the bed, for example.
The operating bed 22 is rotatably mounted on the fixed bed 21 and is a part of the bed formed in a substantially rectangular frame shape so as to be able to maintain an inclination at an arbitrary angle toward the center of the bed.

Further, the operating bed 22 is a fixed bed 21.
It is rotatably provided on the center side of the fixed bed 21 via a rotation shaft 23, and is formed to be able to rise and tilt toward the center of the fixed bed 21.
A substantially semi-cylindrical pillow 22a is formed in a bulging manner at the axial end portion of the end portion 1.

On the other hand, the actuating device 3 has a pinion 24 formed in a part of the rotating shaft 23, and is provided with a rack 31a that meshes with the pinion 24, and is oriented in the axial direction of the fixed bed 21. A rack shaft 31 is formed to be able to reciprocate while being guided by a guide 21c provided on the fixed bed 21, and one end (free end) is connected to the rack shaft 31, and the other end is connected to the valve device 4. A bellows made of a flexible material such as rubber or synthetic resin is provided in communication with the rack shaft 31 and expands and contracts according to the increase and decrease of the introduced air pressure controlled by the valve device 4 and the air supply device 5, and reciprocates on the rack shaft 31. It consists of 32.

Further, the valve device 4 has the bellows 3 at one end.
The opening ends of 2 are fitted and locked so that they can communicate with each other, and a main passage 41 is bored in the horizontal direction, and the main passage 4
The main passage 41 is perforated in the vertical direction perpendicular to 1.
Together with this, an introduction passage 42 is formed in a substantially inverted T-shape, and a discharge hole 44 is bored at the upper end of a discharge chamber 43 provided in communication with the main passage 41 so as to communicate with the atmosphere. , and an opening/closing valve 45 is eccentrically and rotatably provided in the discharge chamber 43 and biased by a spring 46 so that the discharge hole 44 can be opened and closed.

Further, a check valve 47 is provided in the main passage 41 between the introduction passage 42 and the passage to the discharge chamber 43,
When compressed air is introduced from the introduction passage 42, it is opened, and when air is discharged from the discharge hole 44 and when air introduction from the introduction passage 42 is stopped, the middle part of the main passage 41 is closed, and air is not allowed to enter the introduction passage 42. prevent backflow.

Note that 48 is a check valve.

Further, the opening/closing valve 45 has an external operating knob 45a projecting outward, and is configured to rotate eccentrically by operating the operating knob 45a to open and close the discharge hole 44.

On the other hand, the air supply device 5 includes an introduction pipe 51 formed in a flexible pipe shape, one end of which communicates with the open end of the introduction passage 42 of the valve device 4 and is fitted and locked therein. The other end of the introduction pipe 51 is connected to the air pump 52, which supplies compressed air to the valve device 4 through the introduction pipe 51. The air pump 52 rotates in mesh with, for example, a motor (not shown), a switch that turns the motor on and off, a reduction gear consisting of a group of gears meshing with the output gear of the motor, and an output shaft of the reduction gear. The pump may be constructed of a cam and a bellows that is actuated by the cam and supplies compressed air to the outside, but the pump is of course not limited to this and may have other constructions.

Note that 21d is a cover that covers the rear end of the operating bed 22, the operating device 3, and the valve device 4 from below the fixed bed 21, and is provided on the lower surface of the fixed bed 21.

Next, its effect will be explained.

First, the on-off valve 45 is closed so as to close the discharge hole 44.
After operating the operating knob 45a, the switch (not shown) of the air pump 52 is turned on to operate the air pump 52 and supply compressed air to the introduction passage 42 of the valve device 4 through the introduction pipe 51.
Then, the compressed air introduced from the introduction passage 42 is introduced into the main passage 41, increases the air pressure within the valve device 4, and is introduced into the bellows 32. At this time, the bellows 32 is gradually expanded as the air pressure inside the bellows 32 increases,
The rack shaft 31 moves forward (forward movement), and the rack shaft 31
The pinion 24 meshing with the rack 31a is rotated. As a result, the shaft 23 on which the pinion 24 is installed also gradually rotates, causing the operating bed 22 to gradually rise from a horizontal state toward the center of the fixed bed 21, thereby changing the inclination angle. As it increases, it begins to tilt to the tilted state shown by the imaginary lines in Figures 1 and 2.

In this case, in order to stop the operating bed 22 at a predetermined inclination angle and maintain the inclination state, the operation of the air pump 52 is stopped by turning off the switch of the air pump 52, and the supply of compressed air to the valve device 4 is stopped. By stopping the operation bed 22 and stopping the rotation of the operation bed 22, the operation bed 22 can be stopped and maintained at a predetermined inclination angle, for example, as shown in the imaginary lines in FIGS.

On the other hand, when returning the operating bed 22 from the inclined state to the horizontal state, the operation knob 45a is operated to rotate the on-off valve 45 to release the discharge hole 44 from the closed state. By communicating with the valve device 4, the compressed air in the valve device 4 is discharged into the atmosphere through the discharge chamber 43 and the discharge hole 44. Then, due to the pressure drop in the valve device 4 due to the discharge of compressed air from the discharge hole 44, the bellows 32 begins to gradually contract, and accordingly the rack shaft 31 also moves backward (backward movement) and engages with the rack 31a. pinion 2
4, the operating bed 22 can be rotated in the horizontal direction and returned to its original horizontal state as shown by solid lines in FIGS. 1 and 2, that is, the state in which it is fitted into the fitting recess 21b.

In this way, by operating the on-off valve 45 of the valve device 4 and the switch of the air pump 52 of the air supply device 5, the air pressure inside the valve device 4 is increased or decreased, and the actuating device 3 is actuated. The operating bed 22 can be maintained at any angle of inclination between a horizontal position and a vertical position.

Therefore, if a doll or the like is laid down on the bed main body 2, the doll or the like can be changed to any desired state from a sleeping state to a state where the upper body is raised.

Since the present invention is configured as described above, it has the following excellent practical effects.

(1) Not only can the bed be kept horizontally, but also the operating bed, which is a part of the bed, can be maintained at an arbitrary inclination angle, resulting in a high-class bed toy.

(2) For example, by placing the doll lying on the bed and activating the actuating bed, the doll can be changed to any desired state from the sleeping state to the state where the upper body is raised. Since you can play with it in a different way than with normal bed toys, you can play with it in a more interesting way when playing with hospital toys.

(3) The operating bed, which is a part of the bed, can be maintained at any desired inclination angle simply by operating the air pump switch and on-off valve operating knob, making it extremely easy to operate and even small children can handle it easily. be able to.

(4) Since the extension and contraction stroke of the bellows is converted into rotational motion by the rack gear and pinion gear to rotate the operating bed, the bellows can be constructed with a small amount of air inflow and outflow, allowing quick rotational operation of the operating bed. It has advantages such as flexibility in the arrangement position and the ability to install it in a location that cannot be seen from the outside, so it will not be damaged by handling by children, etc., and productivity is good because there is flexibility in the shape of the bellows.
