As shown in FIG. 6, the other end of the hydraulic damper 54 is rotatably mounted on a rotation shaft 75 a of a mounting base 75 provided on the inner wall surface of the side plate 12. The hydraulic damper 54 is normally in a locked state and its length is fixed, but when the lock is released by operating the lock releasing means 54a provided on the other end side, the internal elastic body It acts to extend its length. At this time, by applying an external force exceeding the elastic force of the elastic body, the elastic body can be contracted instead of expanded. Further, an operation unit 77 for remotely operating the unlocking means 54a is attached to the outside wall of the side plate 12 outside the storage space A. Note that the foot-side top plate 21 can be rotated only in a direction in which the top plate 21 is lifted by a ratchet mechanism (not shown), and is restricted from turning in other directions.
The inclination angle of the top plate 21 can be held in a plurality of stages. When the top plate 21 is rotated by a predetermined angle or more, the movement restriction in the other direction is released, and the top plate 21 can be returned to the original horizontal state.

In the storage-type bed having the above configuration, each of the top plates 19, 20, and 21 is used in a horizontal state when sleeping. At this time, the stopper mechanism 40 is in the state shown in FIG. 2 and 7 when reclining
The top plates 19 and 21 are raised as shown in FIG. To raise the top plate 19, the operation unit 77 is pulled, the lock of the hydraulic damper 54 is released, and the hydraulic damper 54 is extended. Then, the passive arm 53 rotates about the rotation shaft 50, and the rotation arm 50 rotates.
The support arm 52 also rotates with the rotation of. More specifically, the base end 55 of the support arm 52 rotates together with the rotation of the rotation shaft 50, and the support 57 supported by the restricting portion 62 of the base end 55 rotates with the base end 55. I do. Since the support portion 57 supports the top plate 19 via the wheels 65,
The top plate 19 rises up, and enters a reclining state. When the top plate 19 has reached the desired angle, the operation unit 77 is returned to the original position and the hydraulic damper 54 is locked. The operation unit 77
When the weight is applied to the top board 19 when the lock of the hydraulic damper 54 is released by pulling, the hydraulic damper 54 contracts and the top board 19 can be tilted. The force by which the hydraulic damper 54 raises the top plate 19 applies one end of the hydraulic damper 54 to the passive arm 53.
The mounting holes 70, 71 and 72 can be determined.

When the articles are stored in the storage space A (or when the articles are taken out of the storage space A), the top plate 19 may be raised by the hydraulic damper 54 as described above, but as shown in FIG. The top plate 19 may be lifted greatly by hand.
When the top plate 19 is lifted by hand, the base portion 55 of the support arm 52 remains fixed, so that the support portion 57 is
As a result, it rotates following the top plate 19. This prevents the support portion 57 from becoming an obstacle when storing articles in the storage space A. In addition, the reclining angle is set by lifting the foot-side top plate 21 by hand.

In the above-mentioned storage type bed, the upper body of the lying person can be raised by lifting the head-side end of the head-side top plate 19, and the reclining state can be achieved.
In addition, by lifting the foot-side end of the foot-side top plate 21, the sole of the lying person can be supported, and the posture can be stably maintained. Then, the person lying down can operate the operating section 77 to operate the top plate 19 in the lying state. The hydraulic damper 54 has mounting holes 70 to 7 for the passive arm.
2, the driving force of the hydraulic damper 54 can be easily changed.

Although the hydraulic damper 54 is used as a drive source of the stopper mechanism 40, it may be a gas damper or the like, or may be an electric damper or the like in addition to the manual damper.

[0028]

As described above, in the retractable bed according to the present invention, the reclining angle of the top plate can be easily changed by operating the damper to rotate the support arm. The support arm is divided into a base end and a support part, and the support part is urged by the top plate, so when the top plate is opened without using a damper, the base end is fixed and supported The part rotates following the top plate. Therefore, when the articles are stored in the storage section, it is possible to prevent the support section from hindering the loading and unloading of articles. In addition, since one end of the damper can be detachably attached to a plurality of positions in the longitudinal direction of the passive arm, transmission of the damper driving force to the passive arm can be easily adjusted. Furthermore,
Since the operation unit of the damper is provided outside the storage unit, the operation unit can be operated while the person lies on the bed.
