Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
87 words
A load-bearing pallet comprising a pair of substantially identical frame members having a plurality of spaced openings therein which are positioned to be vertically aligned and connectors members received into said openings for interconnecting said frame members, each of said connector members including a substantially circular hollow central core member having a plurality of flexible tangs extending from opposite ends thereof and received into said openings of respective frame members to releaseably interconnect said frame members, and an inwardly-directed force-absorbing flange intermediate opposite ends of said core.
Claim 2
Dependent Claim
87 words
A load-bearing pallet comprising a pair of substantially identical frame members having a plurality of spaced openings therein which are positioned to be vertically aligned and connectors members received into said openings for interconnecting said frame members, each of said connector members including a substantially circular hollow central core member having a plurality of flexible tangs extending from opposite ends thereof and received into said openings of respective frame members to releaseably interconnect said frame members, and an inwardly-directed force-absorbing flange intermediate opposite ends of said core.
Claim 3
Dependent Claim
44 words
A load-bearing pallet as defined in claim 1, in which said frame members are substantially rectangular with connector members at least each corner of said frame members, said connector members maintaining said frame members spaced from each other to define forklift tine receiving slots.
Claim 4
Dependent Claim
51 words
A load-bearing pallet as defined in claim 1, in which each connector member has a plurality of integral spokes extending from the core between said tangs with a sleeve integral with the free ends of said spokes, said spokes and sleeve defining planes that engage adjacent surfaces of respective frame members.
Claim 5
Dependent Claim
29 words
A load-bearing pallet as defined in claim 3, in which said sleeve has tapered portions between adjacent pairs of spokes and in which alternating tapered portions are reversely tapered.
Claim 6
Dependent Claim
29 words
A load-bearing pallet as defined in claim 1, in which said core has inner longitudinal ribs extending from said flange to a free end of each of said tangs.
Claim 7
Dependent Claim
40 words
A load-bearing pallet as defined in claim 5, in which said tangs on respective ends of said core are circumferentially offset from each other and each tang has a tapered barb on an outer surface aligned with an inner rib.
Claim 8
Dependent Claim
94 words
A load-bearing pallet as defined in claim 3, in combination with a separator tool for separating said connector from said frame members, said tool comprising a main body that is tapered from substantially a point at one end with a slot extending from said one end, said slot having a width that is greater than the diameter of said core so that said tool can be forced between said plane and an adjacent surface of said frame member to apply sufficient force to flex said tangs and release said connector from said frame member.
Claim 9
Dependent Claim
80 words
A connector for use in interconnecting a pair of frame members to form a pallet, comprising a central hollow core member having slots extending from opposite ends to produce a plurality of flexible tangs at opposite ends of said core member, a plurality of spokes extending from the periphery of said core member between said tangs, a sleeve surrounding said core member and being integral with outer ends of said spokes and an inwardly-directed integral force-absorbing flange between said tangs.
Claim 10
Dependent Claim
80 words
A connector for use in interconnecting a pair of frame members to form a pallet, comprising a central hollow core member having slots extending from opposite ends to produce a plurality of flexible tangs at opposite ends of said core member, a plurality of spokes extending from the periphery of said core member between said tangs, a sleeve surrounding said core member and being integral with outer ends of said spokes and an inwardly-directed integral force-absorbing flange between said tangs.
Claim 11
Dependent Claim
28 words
A connector as defined in claim 8, in which said hollow core member is circular and said slots terminate in close proximity to planes defined by said spokes.
Claim 12
Dependent Claim
46 words
A connector as defined in claim 9, in which each of said tangs has a barb formed adjacent a free edge thereof, each of said barbs having a lower flat edge extending substantially parallel to said planes and being tapered toward free ends of said tangs.
Claim 13
Dependent Claim
28 words
A connector as defined in claim 9, in which said sleeve has tapered portions between each adjacent pair of spokes and in which alternating portions are reversely tapered.
Claim 14
Dependent Claim
22 words
A connector as defined in claim 10, in which said core member has integral reinforcing ribs aligned with each of said barbs.
Claim 15
Dependent Claim
16 words
A connector as defined in claim 8, in which said connector is injection molded from plastic.
Claim 16
Dependent Claim
137 words
A load-bearing pallet comprising a pair of substantially identical frame members having a plurality of spaced openings therein which are positioned to be vertically aligned and connector members received into said openings for interconnecting said frame members, each of said connector members including a substantially circular central core member having a plurality of flexible tangs extending from opposite ends thereof, each connector member having a plurality of integral spokes extending from the core between said tangs with a sleeve integral with the free ends of said spokes, said spokes and sleeve defining planes that engage adjacent surfaces of respective frame members, said sleeve having tapered portions between adjacent pairs of spokes and in which alternating tapered portions are reversely tapered, said tangs being received into said openings of respective frame members to releasably interconnect said frame members.
Claim 17
Dependent Claim
137 words
A load-bearing pallet comprising a pair of substantially identical frame members having a plurality of spaced openings therein which are positioned to be vertically aligned and connector members received into said openings for interconnecting said frame members, each of said connector members including a substantially circular central core member having a plurality of flexible tangs extending from opposite ends thereof, each connector member having a plurality of integral spokes extending from the core between said tangs with a sleeve integral with the free ends of said spokes, said spokes and sleeve defining planes that engage adjacent surfaces of respective frame members, said sleeve having tapered portions between adjacent pairs of spokes and in which alternating tapered portions are reversely tapered, said tangs being received into said openings of respective frame members to releasably interconnect said frame members.
