Abstract
Abstract An inflatable securing arrangement includes support means having a longitudinally extending annular elastomer body bonded thereto. An annular reinforcing is also secured to the support means and extends longitudinally thereof, and gripping means are carried by the support means, such gripping means extending longitudinally within the elastomer body whereby movement of the elastomer body by fluid pressure inwardly relative to the support means urges the gripping means inwardly relative to the support means for engaging an object positioned in the support means.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
88 words
An inflatable securing arrangement comprising: a. support means; b. an annular elastomer body carried by said support means; c. gripping means carried by said support means and extending longitudinally within said annular elastomer body whereby said elastomer body and gripping means may be moved inwardly relative to said support means; and d. reinforcing means extending longitudinally of said elastomer body, said reinforcing means having a pair of reinforcing sheaths each having first ends secured to said support means and second ends terminaing in spaced relation to each other.
Claim 2
Dependent Claim
88 words
An inflatable securing arrangement comprising: a. support means; b. an annular elastomer body carried by said support means; c. gripping means carried by said support means and extending longitudinally within said annular elastomer body whereby said elastomer body and gripping means may be moved inwardly relative to said support means; and d. reinforcing means extending longitudinally of said elastomer body, said reinforcing means having a pair of reinforcing sheaths each having first ends secured to said support means and second ends terminaing in spaced relation to each other.

Dependent Claim
19 words
The invention of claim 1 wherein said reinforcing sheaths are surround on each side by said annular elastomer body.
Claim 4
Dependent Claim
20 words
The invention of claim 1 wherein said reinforcing sheaths are positioned to contact said elastomer body and said gripping means.
Claim 5
Dependent Claim
29 words
The invention of Claim 1 wherein said reinforcing sheaths are positioned to contact said elastomer body and position said elastomer body between said gripping means and said reinforcing sheaths.
Claim 6
Dependent Claim
118 words
A single unit arrangement for exerting a securing force on a longitudinally extendable member including: a. support means; b. an annular elastomer body thereon and extendable therein: c. gripping means carried by said support means and extending longitudinally of said annular elastomer body whereby said elastomer body and gripping means may be moved inwardly relative to said support means; d. said support means including an annular longitudinally extending member; e. conduit means for supplying fluid pressure between said annular member and said elastomer body for expansion of said elastomer body and gripping means inwardly of said support means to grip the longitudinally extending member; and f. power means for moving said annular member and engaged longitudinal member longitudinally.
Claim 7
Dependent Claim
118 words
A single unit arrangement for exerting a securing force on a longitudinally extendable member including: a. support means; b. an annular elastomer body thereon and extendable therein: c. gripping means carried by said support means and extending longitudinally of said annular elastomer body whereby said elastomer body and gripping means may be moved inwardly relative to said support means; d. said support means including an annular longitudinally extending member; e. conduit means for supplying fluid pressure between said annular member and said elastomer body for expansion of said elastomer body and gripping means inwardly of said support means to grip the longitudinally extending member; and f. power means for moving said annular member and engaged longitudinal member longitudinally.
