The characteristics of the stretcher

A second aspect of the invention is a stretcher characterized in that the sliding of the slide mechanism is made by the expansion and contraction of a constant force spring. By using a constant force spring in the slide mechanism for changing up/down the height of the stretcher, the up/down movement is performed smoothly. As a result, an effect is that a patient can be free from uneasiness or pain during the up/down movement.

A fourth aspect of the invention is a medical stretcher characterized in that the front caster is an un-turnable fixed caster. By adopting the un-turnable fixed caster for the front casters, it is possible to prevent the stretcher from staggering resulting in a stable conveyance.

A fifth aspect of the invention is a stretcher characterized in that a stopper is disposed to the right and left front fixed casters respectively, and the right and left stoppers are interlocked with each other. The front casters are un-turnable fixed casters, and the right and left casters are provided with stoppers, and these right and left stoppers are interlocked. Accordingly, by stepping on either one stopper of these right and left front fixed casters, the right and left casters can be fixed at the same time. As a result, the stretcher can be stopped stably.

A sixth aspect of the invention is a ambulance stretcher characterized in that the litter can be fixed by a key-like hook of the upper frame. When the litter is placed on the stretcher, the litter can be fixed and unfixed easily by means of the key-like hooks provided to the upper frame. Further, since the fixing means are disposed at the outer sides of the upper frame, it is easily checked whether the litter is fixed. As a result, the litter with a patient thereon can be fixed to the stretcher and be conveyed with security.

A seventh aspect of the invention is a stretcher characterized in that front leg and rear leg slide mechanisms are provided in a lower portion of the upper frame. By disposing the front leg and rear leg non-step stopper mechanisms in a lower portion of the upper frame, it is possible to prevent the stopper mechanism from being exposed to the external. As a result, such a danger as a foreign matter is caught by the stopper mechanism during operation is eliminated and a satisfactory appearance is realized as well.
