Abstract

A retractable brace for an ambulance attendant for use in an ambulance is disclosed. A lockable scissors mechanism is used to move an anchoring platform between a fully extended substantially vertical position adjacent the attendant'"'"'s work area for securing the ambulance attendant thereto, and a stowed fully retracted substantially vertical position against the side wall of the ambulance. The plate can be locked in a number of positions.

Claims

1. A retractable brace for an ambulance attendant for use in an ambulance, comprising a plate having two sides and upper and lower ends, said plate being moveable between a fully extended substantially vertical position adjacent the attendant'"'"'s work area, and a stowed fully retracted position against the side wall of the ambulance, further comprising means for locking the plate in at least said extended and said stowed positions, and means for securing the ambulance attendant to said plate.

2. A brace as recited in claim 1, in which said plate is moveable between said extended and said stowed positions by virtue of a scissors mechanism, said mechanism comprising:

at least one first member having two ends, one end being pivotally connected near one end of the plate and defining an acute angle with respect to the plate, and the other end being pivotally connectable to the ambulance;

at least one second member having two ends, said second member being pivotally connected to a central portion of said first member and moveably connected near the other end of the plate from said first member, the end of said second member remote from said plate being moveably connectable to the ambulance, said second member being lockable in at least two fixed positions with respect to said first member, said two positions corresponding to said fully extended position and said stowed position of said plate.

3. A brace as recited in claim 2, in which each said first member is pivotally connected near the upper end of the plate.

4. A brace as recited in claim 2, in which each said second member is lockable by virtue of the end thereof adjacent said plate being moveable along a rail attached to said plate, said brace including means for securing said member on said rail.

5. A brace as recited in claim 4, in which said second member is securable to said rail at a number of positions, whereby said plate may be positioned at a corresponding number of locations.

6. A brace as recited in claim 5, in which said second member is securable by virtue of manual rotation of a slotted camshaft into and out of engagement with a tongued member connected to said second member.
