Abstract
A fitting is provided which facilitates the loading of a stretcher onto a platform, such as the bay of an ambulance. The fitting includes a pivotable mounting having a trailing larger diameter wheel and a leading smaller diameter wheel. Pivoting is such that the leading wheel is adapted to ride up onto the platform and then pivot downwardly allowing the trailing wheel to ride up over the rear edge of the platform as the stretcher is pushed into the ambulance. A skid block is preferably formed integrally with the mounting.

A stretcher undercarriage adapted to ride tip over an edge of a surface, comprising, a patient support platform including opposed frame members having a top leading edge and a pair of collapsible wheeled supports, and an arrangement comprising a pair of individually pivotable wheeled devices fitted to said opposed stretcher undercarriage frame members adjacent said top leading edge thereof, wherein each of said devices comprises a pivotable mounting on which a leading wheel and a trailing wheel are co-planarly supported in such a manner that the leading wheel is adapted to ride onto the edge of the surface and then pivot downwardly permitting the trailing wheel to ride up over the edge as the stretcher undercarriage is pushed.
The arrangement for facilitating loading of a stretcher undercarriage onto a surface over an edge thereof, the stretcher undercarriage having opposed frame members with a top leading edge, said arrangement comprising:
- a pair of individually pivotable wheel support devices mountable to the opposed frame members adjacent the top leading edge thereof wherein each of said devices comprises:
- a leading wheel;
- a trailing wheel;
- and,
- a pivotable mounting co-planarly supporting said leading and trailing wheels in such a manner that said leading wheel is adapted to ride onto said surface and then pivot downwardly permitting the trailing wheel to ride up over said edge as the stretcher undercarriage is pushed.
An arrangement for facilitating loading a leading edge of a stretcher undercarriage having upper opposed frame members over an edge and onto a loading bay floor of an ambulance, said arrangement comprising:
- a pair of wheeled devices for fitting to the frame members adjacent the leading edge of the stretcher undercarriage, wherein each of said wheeled devices comprises:
- an attachment for one of said opposed frame member;
- a mounting on which a leading wheel and a trailing wheel are co-planarly supported in such a manner that said leading wheel is adapted to ride onto the floor and then pivot downwardly permitting said trailing wheel to ride up over the edge as the stretcher is loaded into the ambulance;
- and
- a common axle extending into said attachment, said mounting being pivotable on said common axle.
