Claims
- 1. A conveyor cart for aiding in the placement of a subject to be x-rayed or treated in position in a radiographic apparatus, comprising, in combination:
- an elongated frame;
- a conveyor belt mounted on said frame and along the length thereof to move a subject placed on said belt along the length on said cart from a first position where said subject can be placed on said cart to a second position on said cart where he can be positioned in said radiographic apparatus; and
- coupling means mounted on said frame and connected to said belt and adapted to be actuated by a movable element in said radiograhic apparatus for moving said belt, and means connected between said coupling means and said conveyor belt for amplifying the motion of such a movable element to cause a greater movement of said belt in response thereto.
- 2. The conveyor cart of claim 1 wherein said amplifying means includes a closed linkage mechanism having opposed parallel members pivotally connected together at their ends to form a parallelogram, the junction of two of said members being pivotally connected to said coupling means and responsive to movement thereof and the junction of two other of said members being pivotally connected to said conveyor belt so that relative movment of said junction towards and away from each other causes movement of said belt.
- 3. The conveyor cart of claim 2 wherein the relative movement of said conveyor belt in response to movement of said coupling means is at least three times the relative movement of said coupling means.
