Floor conveyor system
First Claim
1. A floor conveyance system for transporting goods along a preselected conveyance path, said system comprising in combination:
- a drag chain conveyor defining a first surface;
a skid conveyor having one end adjacent said drag chain conveyor and defining a second surface disposed at a level higher than said first surface of said drag chain conveyor, said drag chain and skid conveyors together defining said conveyance path;
conveying frame means operatively engageable in said drag chain and said skid conveyors for supporting goods thereon and to convey said goods along said conveyance path, said frame means including a frame, front and rear pairs of wheels journally mounted to said frame to permit rolling movement across said first surface, said front and rear pairs of wheels being separated in the longitudinal direction by a predetermined dimension, and a pair of elongated parallel skid members fixedly mounted to said frame interiorly with respect to said front and rear pairs of wheels and each skid having a longitudinal length less than said predetermined dimension, said pair of skid members defining a contact surface at a level higher than the rolling contact of said front and rear pairs of wheels with said first surface, said contact surface establishing sliding contact with said second surface when said conveying frame is conveyed along said skid conveyor, and wherein,said front and rear pairs of wheels contact said first surface when said frame means is conveyed along said path by said drag conveyor while said pair of skid members are inoperative, and said front and rear pairs of wheels are disengaged from said rolling contact with said first surface when said pair of skid members come into engagement with said second surface of said skid conveyor.

Abstract
A floor conveyance system for transporting goods along a preselected conveyance path includes a drag chain conveyor defining a first surface and a skid conveyor having one end adjacent to the drag chain conveyor and defining a second surface disposed at a higher level than the first surface of the drag chain conveyor. A conveying frame is operatively engageable with the drag chain and skid conveyors for supporting goods thereon and includes front and rear pairs of wheels to permit for rolling movement of the conveying frame across the first surface and a pair of elongated parallel skid members mounted interiorly with respect to the front and rear pairs of wheels and each having a longitudinal length less than the separation dimension between the front and rear pairs of wheels. The parallel skid members establish sliding contact with the second surface when the conveying frame is conveyed along the skid conveyor. Thus, the front and rear pairs of wheels contact the first surface when the frame is conveyed by the drag conveyor while the pair of skid members are inoperative, and the front and rear pairs of wheels are disengaged from the first surface when the pair of skid members come into engagement with the second surface of the skid conveyor.
