Handling device with flexible link chains and bars
Handling device of the present invention includes spaced-out transverse bars connected through their ends to endless lateral drive chains made of links. The chains include a series of flexible links connected through bars.
1. A handling apparatus comprising:
a plurality of bars extending in spaced relation to each other; and
a pair of endless drive chains connected to said plurality of bars, said plurality of bars extending in transverse relation to said pair of endless drive chains, each of said endless drive chains comprising:
a plurality of links in which a pair of adjacent links of said plurality of links are connected together by an end of the bar, one of said pair of adjacent links having an end overlying an end of another of said pair of adjacent links, said end of the bar received in a port formed in said ends of said pair of adjacent links such that said pair of adjacent links do not swivel with respect to each other at a linkage axis at said port in said ends of said pair of adjacent links, each of said plurality of links being flexible along a length thereof, each of said plurality of links comprising:
an internal armature formed of a high tensile strength flexible braid, said internal armature having a loop at opposite ends thereof, said loop having a rigid eyelet received therein, said rigid eyelet having said port therein, said internal armature being covered with a flexible coating.
2. The handling apparatus of claim 1 , the bar being removably affixed to the link.
3. The handling apparatus of claim 1 , each of said plurality of links having a bulge on a lateral face thereof between an adjacent pair of said plurality of bars, each of said pair of endless drive chains having a generally uniform width.
4. The handling apparatus of claim 1 , the end of each of said plurality of bars having a polygonal cross-section.
5. The handling apparatus of claim 1 , further comprising:
a component mounted fixedly to the bar between said pair of endless drive chains.
6. The handling apparatus of claim 1 , further comprising:
a component mounted in a tilted manner to the bar between said pair of endless drive chains.
7. The handling apparatus of claim 1 , the end of the bar having a shape that is complementary to the shape of the port.
8. The handling apparatus of claim 2 , further comprising:
a U-shaped fork clip having a pair of flat branches and a bottom extending between said pair of flat branches, said fork clip affixed over the end of the bar.
9. The handling apparatus of claim 8 , said fork clip having an open end opposite said bottom, each of said pair of flat branches having an end bent transversely at said open end.
10. The handling apparatus of claim 8 , one of said pair of flat branches having a lug extending inwardly in a direction toward the other of said pair of flat branches, the bar having an indentation adjacent the end thereof, said lug cooperatively received in said indentation.
11. A handling apparatus comprising:
a plurality of bars extending in spaced relation to each other; and
a pair of endless drive chains connected to said plurality of bars, said plurality of bars extending in transverse relation to said pair of endless drive chains, each of said endless drive chains comprising:
a plurality of links in which a pair of adjacent links of said plurality of links are connected together by an end of the bar, one of said pair of adjacent links having an end overlying an end of another of said pair of adjacent links, said end of the bar received in a port formed in said ends of said pair of adjacent links such that said pair of adjacent links do not swivel with respect to each other at a linkage axis at said port in said ends of said pair of adjacent links, each of said plurality of links being flexible along a length thereof, the bar being removably affixed to the link; and
a U-shaped fork clip having a pair of flat branches and a bottom extending between said pair of flat branches, said fork clip affixed over the end of the bar, one of said pair of flat branches having a flexible tab protruding from an outer face thereof, said port having a notch formed on an internal surface thereof, said flexible tab cooperating with said notch.
12. The handling apparatus of claim 11 , further comprising:
a tapping screw threadedly secured to the end of the bar and to said port.
13. The handling apparatus of claim 12 , said wall of said port having a groove extending parallel to an axis of said port, said tapping screw received partially in said groove.
14. The handling apparatus of claim 13 , said groove having a counterbore formed at an outer face of the link.
15. The handling apparatus of claim 13 , further comprising:
a U-shaped metallic fork having a pair of parallel flat branches extending over the end of the bar, said pair of parallel flat branches each having an end bent transversely thereto so as to overlie an internal face of the link.
