Abstract
Abstract A locking ring having a number of arched metal segments and a number of arched rubber segments positioned between the metal segments. The rubber segments are fixedly connected with the metal segments by vulcanization. The locking ring when in mounted position is axially fixed in at least one direction to a surface and being resiliently expandable and/or compressible against the action of the rubber material.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
107 words
A locking ring for axially fixing an annular member to a substantially cylindrical member where one of the members is provided with an annular groove and the other member is provided with a shoulder, the locking ring comprising a plurality of arched metal segments and a plurality of arched elastic segments, each adjacent pair of metal segments being separated by and bonded to an intervening elastic segment to form a generally flat resilient annular ring, the ring being deformable to place an annular part thereof in the annular groove with another annular part thereof engageable with the shoulder to limit relative axial movement of the two members.
Claim 2
Dependent Claim
107 words
A locking ring for axially fixing an annular member to a substantially cylindrical member where one of the members is provided with an annular groove and the other member is provided with a shoulder, the locking ring comprising a plurality of arched metal segments and a plurality of arched elastic segments, each adjacent pair of metal segments being separated by and bonded to an intervening elastic segment to form a generally flat resilient annular ring, the ring being deformable to place an annular part thereof in the annular groove with another annular part thereof engageable with the shoulder to limit relative axial movement of the two members.
Claim 3
Dependent Claim
63 words
The locking ring of claim 1 wherein the cylindrical member is a shaft and is the member provided with the annular groove and wherein the annular member comprises a two ring bearing one ring of which comprises the said shoulder, the arched elastic segments being circumferentially expandable to allow the ring to be passed over the shaft and into position in the groove.
Claim 4
Dependent Claim
66 words
The locking ring of claim 1 wherein the cylindrical member comprises a shaft having a two ring bearing thereon forming the said shoulder and wherein the annular member receives the shaft and bearing and is the member provided with the annular groove, the arched elastic segments being circumferentially compressible to allow the ring to be passed into the annular member and expand into the annular groove.
