/? '% Wheel devices generally consist of four swivel wheels. Special Publication No. 3-24536, Special Publication No. 56
There is an example of this in Publication No.-34298. When transferring a patient from or to a bed, the general procedure is to roughly push the stretcher into the aisle between the rows of beds and then push it laterally to close the gap between the bed and the stretcher. . This is possible because all four wheels are swivel wheels, but pushing the stretcher sideways and aligning the swivel wheels in that direction is a task that requires considerable force. By the way, the stretchers described in the above two publications all have a function for loading and unloading patients using belts, have complex mechanisms built in, and are naturally user-friendly. Moving this J: Una Stretch A1- laterally through a narrow passageway that makes it difficult to apply force is a considerable burden on a weak female caregiver.

It was also impossible to incorporate a self-propelling function to make long-distance movement easier with the four-wheel swivel system.

<Objective of the Invention> An object of the present invention is to provide a traveling means that can easily move laterally even a heavy patient transport device equipped with special functions.

<Structure of the Invention> The patient transport device of the present invention is equipped with a lateral movement wheel group whose direction is fixed in the direction of lateral movement at the side of the normal movement wheel group. A group of wheels for lateral movement alternates the role of support.

<Example> An example will be explained below based on the figures. In Figure 8,

The scoop bell l-3'I and the crawler 35 are oriented perpendicularly to the longitudinal direction of the moving platform 11. Each movable deck 31, 32, 33 has a motor box 3G at its end: 'FiL, in which a reduction gear (=J motor 37, 38) is housed. For sprockets 1 to 39, install an electric motor (38 beams ['' - 35 rods [1 socket 40
The motors are connected to each other by a non-slip transmission means such as a engine or a timing belt to transmit rotation.The power source for the electric motors 37 and 38 is a battery as in the case of an electric actuator. Each of the movable decks 31, 32 and 33 has a moving guide 41 fixedly installed in the center thereof.

The moving kite 41 is a rectangular pipe-shaped member with a slit on the lower surface to the right, and receives a rail 42 fixed to the upper surface of each support deck 19.20.degree. 21. The shape of the rail 42 is shown in FIG. The portion far from the electric motor box 36 has an overhanging portion 43 at its upper end, and this overhanging portion 7'13 prevents the moving guide 41 from coming off upward. However, there is some space between the overhanging portion 43 and the lower edge of the moving guide 41.
The movable decks 12, 31, 32, and 33 can float within a certain height range. This means that the movable deck can be moved relative to the support deck as shown in FIG. In the illustrated embodiment, the moving guide 41 is
