Abstract
Abstract A wheel construction having a wheel with an axially extending hold therethrough and having a first diameter. A preassembled bearing housing having a second diameter less than the first diameter is located inside the hole of the wheel. The axis of the bearing housing is concentric with the outside diameter of the wheel. The difference between the first and second diameters defines a spacing therebetween. A moldable synthetic resin material fills the aforesaid spacing and effects a securement of the bearing housing to the wheel.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
111 words
A wheel construction, comprising: wheel means having an axially extending hole therethrough, said hole having a first diameter; bearing means; bearing housing means for housing said bearing means therein and having a second diameter less than said first diameter, said bearing housing means being located inside said hole with the center of said bearing housing means being concentric with the outside diameter of said wheel means, the difference between said first and second diameters defining a spacing therebetween; a moldable, synthetic resin material filling said spacing; and means for positively securing said moldable, elastomeric material in said spacing to effect a securement of said bearing housing means to said wheel means.
Claim 2
Dependent Claim
111 words
A wheel construction, comprising: wheel means having an axially extending hole therethrough, said hole having a first diameter; bearing means; bearing housing means for housing said bearing means therein and having a second diameter less than said first diameter, said bearing housing means being located inside said hole with the center of said bearing housing means being concentric with the outside diameter of said wheel means, the difference between said first and second diameters defining a spacing therebetween; a moldable, synthetic resin material filling said spacing; and means for positively securing said moldable, elastomeric material in said spacing to effect a securement of said bearing housing means to said wheel means.
Claim 3
Dependent Claim
33 words
A wheel construction according to claim 1, wherein said moldable, synthetic resin material occupies the entirety of said spacing from one axially facing side of said wheel means to the other side thereof.
Claim 4
Dependent Claim
14 words
A wheel construction according to claim 1, wherein said synthetic resin material is rigid.
Claim 5
Dependent Claim
15 words
A wheel construction according to claim 3, wherein said synthetic resin material is ABS (acrylonitrile-butadiene-styrene).
Claim 6
Dependent Claim
39 words
A wheel construction according to claim 1, wherein said synthetic resin material is an elastomeric material which is resilient whereby said wheel means is movable relative to said bearing housing means against the resilient urging of said elastomeric material.
Claim 7
Dependent Claim
74 words
A wheel construction according to claim 1, wherein said bearing housing means comprises an axle, a cylindrical sleeve, said bearing means being located between said axle and said cylindrical sleeve to facilitate a rotation of said cylindrical sleeve relative to said axle; and wherein said cylindrical sleeve is made of a second moldable synthetic resin material; and wherein said spacing is located between the outside diameter of said cylindrical sleeve and said wheel means.
Claim 8
Dependent Claim
37 words
A wheel construction according to claim 6, wherein the first-mentioned synthetic resin material has a rigid characteristic; and wherein said second moldable synthetic resin material of said cylindrical sleeve is an elastomeric material having a flexible characteristic.
Claim 9
Dependent Claim
37 words
A wheel construction according to claim 6, wherein the first-mentioned synthetic resin material is an elastomeric material having a flexible characteristic; and wherein said second moldable synthetic resin material of said cylindrical sleeve has a rigid characteristic.
Claim 10
Dependent Claim
25 words
A wheel construction according to claim 6, wherein both of said first-mentioned synthetic resin material and said second synthetic resin material have a rigid characteristic.
Claim 11
Dependent Claim
27 words
A wheel construction according to claim 6, wherein said first-mentioned synthetic resin material and said second synthetic resin material are an elastomeric material having a resilient characteristic.
Claim 12
Dependent Claim
64 words
A wheel construction according to claim 6, wherein said second synthetic resin material is an elastomeric material having a radially flexible characteristic to accommodate an encirclement of different combinations of different diameter axle and bearing means assemblies to result in varying outside diameters for said cylindrical sleeve with each different combination to facilitate a use of the same cylindrical sleeve for said different combinations.
Claim 13
Dependent Claim
28 words
A wheel construction according to claim 11, wherein said second moldable, elastomeric material has a hardness in the range of 75 Shore A to 55 Shore D Durometer.
Claim 14
Dependent Claim
41 words
A wheel construction according to claim 6, wherein said means for positively securing said wheel means to said bearing housing means comprises rib means on at least one of said sleeve and said wheel means and extending radially into said spacing.
Claim 15
Dependent Claim
28 words
A wheel construction according to claim 1, wherein said moldable synthetic resin material has a hardness in the range of 75 Shore A to 55 Shore D Durometer.
Claim 16
Dependent Claim
99 words
A wheel construction, comprising: wheel means having an axially extending hole therethrough, said hole having a first diameter; bearing means; bearing housing means for housing said bearing means therein and having a second diameter less than said first diameter, said bearing housing means being located inside said hole with the center of said bearing housing means being concentric with the outside diameter of said wheel means, the difference between said first and second diameters defining a spacing therebetween; and moldable, synthetic resin means filling said spacing and effecting a securement of said bearing housing means to said wheel means.
Claim 17
Dependent Claim
99 words
A wheel construction, comprising: wheel means having an axially extending hole therethrough, said hole having a first diameter; bearing means; bearing housing means for housing said bearing means therein and having a second diameter less than said first diameter, said bearing housing means being located inside said hole with the center of said bearing housing means being concentric with the outside diameter of said wheel means, the difference between said first and second diameters defining a spacing therebetween; and moldable, synthetic resin means filling said spacing and effecting a securement of said bearing housing means to said wheel means.
