Description

  The present invention is a stretcher that can be folded to narrow the occupied space in a stretcher used for transporting the subject person, bathing, etc. at a care recipient transfer provider, hospital, funeral agent, police, nursing care facility, etc. About.

  Conventionally, a general stretcher has a bed portion disposed above a carriage portion via a pantograph mechanism portion, and the elevating means of the pantograph mechanism portion employs a feed screw system disposed below the bed portion. The bed portion is moved up and down by rotating the handle protruding to the foot side (see, for example, Patent Document 1).

Japanese Patent No. 3543293

  For example, a so-called care taxi that picks up a care recipient to a destination can usually carry two wheelchairs, but some care recipients need to move using a stretcher. Since only the table is placed, after picking up a care recipient using a stretcher, if there is a contact from a caregiver using a wheelchair, you must first return to the office etc. and unload the stretcher. There were issues that had to be resolved, such as being unable to pick up and being able to respond quickly.

  In view of the problem that other care recipients cannot be placed on the stretcher of the feed screw type based on the above-described conventional technology, the bed portion is located at both ends of the bed portion main body portion at the head side portion and the foot side portion. And a feed screw disposed so as to be capable of forward and reverse rotation directly below the bed portion, a feed screw body positioned below the bed body portion, and the feed screw body and a universal joint. Even if there is a feed screw, it has a telescopic connecting rod that is connected below the foot side portion and a handle that is connected to the end of the connecting rod via a universal joint. The bed portion can be folded by reliably swinging the head side portion and the foot side portion upward to solve the above problem.

In short, in the present invention, a bed part is installed above a movable carriage part via an elevating mechanism, and the bed part pivots at both ends of the bed part body part so that the head side part and the foot side part can swing upward. The elevating mechanism crosses in an X-shape, and one end is fixed to be pivotally attached to the carriage and the bed, and the other end is attached to the carriage and the bed so as to be movable in the horizontal direction. It is composed of a pair of pantographs as moving ends and a feed screw portion that is arranged below the bed portion and can be operated on the foot side of the bed portion, and the feed screw portion rotates forward and backward directly below the bed portion. Since it has a feed screw that can be arranged and a nut portion that is provided at the upper moving end and is screwed into the feed screw, it has the same effect as the above-described conventional feed screw type stretcher. It can be made.
In addition, the feed screw includes a feed screw body positioned below the bed body portion, a telescopic connecting rod connected to the feed screw body via a universal joint, and located below the foot side portion. Since it has a handle connected to the end of the connecting rod through a universal joint, it can be in a folded state in which the head side portion and the foot side portion are swung upward by about 90 degrees. If it is folded after use, an empty space will be formed even if it is loaded on the car, so other care recipients can be picked up with the folded stretcher loaded and used for other purposes. However, the space occupied when not in use can be reduced.

  Since the connecting rod has a nested structure with a plurality of cylindrical members having different sizes, and the inner cylindrical member does not rotate around the shaft center with respect to the outer cylindrical member, the connecting rod has a simple structure. It can be realized with a practical effect.

In the foldable stretcher according to the present invention, the bed part 2 is installed above the movable carriage part 1 via the lifting mechanism 3, and the bed part 2 is located on both sides of the bed part body part 4 at the head side. By pivoting the part 5 and the foot side part 6 so as to be swingable upward, specifically, by pivoting the head side part 5 and the foot side part 6 on top of both ends of the bed part body part 4, The downward swing of the head side part 5 and the foot side part 6 in the unfolded state is prevented.

  The elevating mechanism 3 includes a pair of pantographs 7 and 8 crossed in an X shape, and a feed screw portion 9 that is disposed below the bed portion 2 and can be operated on the foot side of the bed portion 2. 7 and 8 head ends are fixed ends that are pivotally attached to the cart unit 1 and the bed unit 2, and the foot ends are attached to the cart unit 1 and the bed unit 2 so as to be movable in the horizontal direction. It is said.

  The feed screw portion 9 is screwed to the feed screw 10 disposed so as to be able to rotate forward and backward immediately below the bed portion 2 and the feed screw 10 provided at the upper moving end (the foot side end portion of the outer pantograph 9). And a nut portion 11 to be used.

  The feed screw 10 is connected to the feed screw main body 12 located below the bed main body portion 4 via the universal joint 13 and the telescopic connecting rod located below the foot side portion 6. 14 and a handle 16 connected to the end of the connecting rod 14 via a universal joint 15.
