Abstract

Abstract A platform conveyor having two laterally adjacent, interconnected rows each having a plurality of flat panel members of plastic material hingedly connected together along transversely extending edges thereof, the upper surface of the interconnected panel members forming a load supporting surface, a plurality of integrally formed eyes along each transversely extending edge of each of the panel members and being aligned to receive an interconnecting transverse bar member which connects both rows of the panel members together to form the conveyor belt, the eyes on one transversely extending edge of each panel being staggered relative to the eyes on the opposite edge thereof, the transverse bar member extending to a stop at one side of a panel member forming one edge of the conveyor belt, and at the other edge of the conveyor belt being retained by a pin inserted through a transverse aperture in the eye, and at least one hook attached to one side of the panel members which engages a web at the edge of the laterally adjacent panel member.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 177 words
In a platform conveyor, the combination comprising two laterally adjacent, interconnected rows each having a plurality of flat panel members of plastic material hingedly connected together along transversely extending edges thereof, the upper surface of said flat panel members being adapted to support a load, a plurality of integrally formed eyes along each transversely extending edge of each of said panel members and being aligned to receive an interconnecting transverse bar member which connects both rows of said panel members together to form a conveyor belt, the eyes on one transversely extending edge of each panel being staggered relative to the eyes on the opposite edge thereof, said transverse bar member extending to a stop at one side of a panel member forming one edge of the conveyor belt, and at the other edge of the conveyor belt being retained by a pin inserted through a transverse aperture in said eye, and at least one hook attached to one side of said panel members, which hook engages a web at the edge of the laterally adjacent member.
Claim 2
Dependent Claim 177 words
In a platform conveyor, the combination comprising two laterally adjacent, interconnected rows each having a plurality of flat panel members of plastic material hingedly connected together along transversely extending edges thereof, the upper surface of said flat panel members being adapted to support a load, a plurality of integrally formed eyes along each transversely extending edge of each of said panel members and being aligned to receive an interconnecting transverse bar member which connects both rows of said panel members together to form a conveyor belt, the eyes on one transversely extending edge of each panel being staggered relative to the eyes on the opposite edge thereof, said transverse bar member extending to a stop at one side of a panel member forming one edge of the conveyor belt, and at the other edge of the conveyor belt being retained by a pin inserted through a transverse aperture in said eye, and at least one hook attached to one side of said panel members, which hook engages a web at the edge of the laterally adjacent member.
Claim 3
Dependent Claim 23 words
Platform conveyor of claim 1 wherein said hooks are removable so as to provide an assembled belt without projections on both edges thereof.
Claim 4
Dependent Claim 23 words
Platform conveyor of claim 1 wherein the panel members have a trapezoidal shape thereby enabling said conveyor to travel in a curved path.
Claim 5
Dependent Claim 20 words
Platform conveyor of claim 1 wherein the integral eyes are interconnected by sturdy webs on the underside of said panels.
