Abstract
Abstract Roller for rolling drawer guides with a wheel journaled on a stud (24) fastened to the running and/or guiding rail of the drawer guide, the wheel having a rim concentric with the longitudinal central axis of the stud (24). The wheel is divided into a hub (16) journaled on the stud (24) and a rim (18) disposed concentrically on the hub, and the rim (18) is mounted on the hub (16) for displacement in the direction of the roller axis of rotation. The rim (18) is held on the hub (16) preferably against rotation in the direction of rotation of the roller.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
84 words
A roller for a running or guide rail of a drawer guide of a piece of furniture, comprising: a stud to be mounted to the rail and having a central axis; and a wheel; said wheel having a hub mounted on the stud so as to be rotatable about said central axis, and also having a rim mounted on the hub so as to be non-rotatable with respect to the hub but displaceable relative to the hub in the direction of the central axis.
Claim 2
Dependent Claim
84 words
A roller for a running or guide rail of a drawer guide of a piece of furniture, comprising: a stud to be mounted to the rail and having a central axis; and a wheel; said wheel having a hub mounted on the stud so as to be rotatable about said central axis, and also having a rim mounted on the hub so as to be non-rotatable with respect to the hub but displaceable relative to the hub in the direction of the central axis.
Claim 3
Dependent Claim
24 words
A roller according to claim 1, wherein the rim and hub have bearing surfaces which are slidable one on the other under slight pressure.
Claim 4
Dependent Claim
30 words
A roller according to claim 2, wherein said hub and said rim have multiple groove connections so as to be displaceable axially but non-displaceable circumferentially with respect to each other.
Claim 5
Dependent Claim
15 words
A roller according to claim 3, wherein the multiple groove connection forms a spline-shaft coupling.
Claim 6
Dependent Claim
16 words

Claim 7
Dependent Claim
39 words
A roller according to claim 5, wherein the key coupling has keys on the hub and keyways on the rim, said keys and keyways having complementary dovetail-shaped cross sections, said keyways having sides biased against flanks of the keys.
Claim 8
Dependent Claim
34 words
A roller according to claim 6, wherein at least the rim consists of a resilient plastic, and wherein the rim has sections between the sides of adjacent keyways, said sections being resiliently flexible walls.
Claim 9
Dependent Claim
18 words
A roller according to claim 7, wherein the walls are formed by arcuate cut-outs extending through the rim.
Claim 10
Dependent Claim
25 words
A roller according to claim 1, wherein the hub and the rim consist of different materials, the material of the rim having noise reducing qualities.
