  When the reclining operation is manually performed by the stretcher of Patent Document 1, the caregiver supports the person being assisted on the stretcher with one hand while operating the lock release lever with the other hand, The standing part on the upper body side, which is drowning, is stood up or laid down. Furthermore, when unlocking the mounting part on the upper body side that is the backrest, the lock release lever is operated with the backrest once lifted and held in order to unlock the backrest and the like once. It was necessary and the operation was troublesome and complicated. In particular, if the caregiver is a woman, supporting the weight of the person being supported and the backrest with one hand is a heavy burden, and there is a problem in terms of ensuring safety and reducing the burden of assistance.

  The prior arts of Patent Documents 2 and 3 are reclined by a ratchet mechanism. In order to avoid an increase in size and cost, such a ratchet mechanism is generally built compactly near the rotation shaft to be locked. . However, when the rotation is restricted at a position close to the axis of a relatively long rotating object such as a backrest, the greater the difference in length, the more dimensional accuracy is required, and at the same time, the strength is secured by increasing the moment. It becomes difficult. Also, the stretcher is mainly used in the sleeping position unlike a general chair, and the ratchet mechanism is constantly overloaded, so the lock performance of the ratchet mechanism due to wear and buckling of the teeth. There is also concern about the decline. Furthermore, two conventional ratchet mechanisms usually need to be provided at both ends of the rotating shaft, and it has been technically difficult to synchronize the two mechanisms. For this reason, only one side is locked due to malfunction, and the placing surface of the stretcher is greatly inclined to cause a fall accident, and the rigidity of the stretcher frame is strongly required to ensure the synchronization, and the frame structure of the stretcher is complicated. However, there is a problem that the weight is increased and the operability is further impaired. In addition, the conventional bathing apparatus is provided with reclining mechanisms on the upper body side and the lower body side in order to accommodate both the upper and lower body of the person being assisted. When complicated, not only cleaning becomes difficult, but there is a problem that the cost, the frequency of failure, and the work load such as cleaning increase due to the provision of two reclining mechanisms.

  The present invention has been made in view of the above-mentioned problems, and can be used to safely transport or transport a person being assisted, a patient, or the like, and reduce the burden on a user such as a helper during the transportation. The purpose is to provide equipment.

According to a second aspect of the present invention, the standing / falling regulation member is provided in the vicinity of the substantially center of the movable mounting portion in the width direction.

  According to a third aspect of the present invention, there is provided a lock member in which the standing / falling regulation member has a cam portion and a lock piece on one of the base and the movable mounting portion, and the base and the movable mounting portion. A step portion for rotating the cam portion by contacting the cam portion and a lock piece abutting portion for contacting the lock piece on the other of the portions, and a standing state from the lying state of the movable mounting portion As the cam part rotates, the cam part contacts the step part and rotates in one direction, whereby the lock piece rotates, and then the movable mounting part rotates from the standing state to the lying state. On the way, the lock piece interferes with the lock piece abutment portion, and further falling of the movable placement portion is restricted and locked, and the movable placement portion is turned from the restricted state to the standing state again. When moved, the cam portion is rotated in the same direction as the one direction at the stepped portion. The lock piece is rotated, thereby characterized that the state of the lock by the locking piece is released.

According to a fourth aspect of the present invention, the movable mounting portion is provided in a symmetrical structure on both sides in the longitudinal direction of the base body.

According to the present invention, when the movable mounting portion is erected, the movable mounting portion is held in a state in which the movable holding portion is firmly held by both of the hands without operating the lock release lever as in the prior art. The part can be operated upright, and the standing posture of the movable mounting part can be adjusted safely. Therefore, even if the assistant is a woman or the person being assisted is heavy, the movable mounting portion can be easily laid down.

Further, it is not necessary to provide two standing / falling regulation members at both ends of the rotating shaft as in the conventional ratchet mechanism, and a predetermined distance from the rotating shaft of the movable mounting portion is used to prevent the standing / falling of the movable mounting portion. Since the rotation can be controlled efficiently and reliably and can be supported in a balanced manner, it can be provided as a single unit in the vicinity of the center in the width direction, so the two mechanisms can be synchronized or an excessive moment can be applied. For this reason, it is not necessary to use high-precision and high-strength parts, and it is possible to efficiently and surely regulate the rotation of the movable mounting portion with the simple and inexpensive configuration.

And, since the movable mounting part urges in the lying down direction, that is, the lock piece abuts on the lock piece abutting part and locks it, inertia force such as shaking of the stretcher during transportation of the stretcher, and the transfer device are obstructed Even if an impact force caused by a collision with an object or a force acting on the stretcher by the person being assisted on the stretcher is applied, the lock is not easily released and it is safe. In addition, when the movable mounting part is backrest, vibration during movement is reduced, and the person being assisted is comfortable, and when the stretcher is immersed in hot water in the bathtub, the movable mounting part is covered. In the case where the lower body side of the caregiver is placed, the inconvenience that the movable body portion on the lower body side floats due to buoyancy can be solved.
