Abstract
A conveyor comprises a plurality of interconnected cradles and a rotatable member mounted in each cradle. The rotatable members extend above the respective cradle for rolling contact with an object placed on the conveyor to allow the objects to move relative to the conveyor.
Claims20
A conveyor comprising:
- a plurality of cradles, each of said plurality of cradles further having a substantially "H" shape;
- a plurality of rotatable members mounted in spaced relationship to said plurality of rotatable cradles, each of said rotatable members further being mounted on each side of the bridge of the "H" shape of each of said plurality of cradles;
- and
- means for rotatably mounting each of said rotatable members in each of said plurality of cradles such that each of said rotatable members extends above each of said plurality of cradles for rolling contact with an object placed on the conveyor.

A conveyor for moving an object, said conveyor comprising:
- a plurality of cradles, each of said plurality of cradles comprising:
- at least two parallel support members;
- and
- transverse spacer means connecting said at least two parallel support members to form a generally "H" shaped cradle;
- a plurality of rotatable members mounted in spaced relationship to said plurality of cradles, each of said plurality of rotatable members having an outer diameter extending above said plurality of cradles for rolling contact with the object placed thereon;
- and
- means for pivoting at least one of said plurality of cradles with respect to at least one other of said plurality of cradles so as to form the conveyor, said pivoting means mounted to said at least two parallel support members of each of said plurality of cradles such that when an object is placed on the conveyor, the object contacts only said plurality of rotatable members for unobstructed rolling contact therewith thereby moving the object along the conveyor without contacting said plurality of cradles.
4 more elements
A conveyor comprising:
- a plurality of cradles each of said plurality of cradles having at least two links, each of said at least two links has, when viewed in plan, a substantially "H" shape with the bridge of the "H" extended to project laterally outwards from the arms of the "H," the links being arranged in parallel transverse rows, the links of adjacent rows being staggered with respect to each other and the arms of adjacent rows overlapping each other when viewed in a transverse direction, such that each cradle is formed by the bridge and one end of the arms of a first link of one row and a bridge extension portion together with one arm of each of a pair of adjacent links on an adjacent row, a plurality of rotatable members mounted in spaced relationship to said plurality of cradles;
- and means for rotatably mounting each of said plurality of rotatable members in each of said plurality of cradles such that each of said plurality of rotatable members extend above each of said plurality of cradles for rolling contact with an object placed thereon.
