Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
115 words
Tool comprising a force-producing device having at least one inflatable thrust producing member displaceable so as to apply a given force, a pivotally displaceable member engageable by said inflatable thrust producing member and pivotally displaceable thereby and a member on which said pivotally displaceable member is pivotally mounted on an axis about which the displaceable member pivots, and wherein said pivotally displaceable member is a lever handle movable relative to another member and forming tongs, and wherein said other member is another lever handle, with said inflatable thrust producing member being disposed between both said lever handles, and including resilient means connected to said lever handles for restoring the tongs to their initial open position.
Claim 2
Dependent Claim
115 words
Tool comprising a force-producing device having at least one inflatable thrust producing member displaceable so as to apply a given force, a pivotally displaceable member engageable by said inflatable thrust producing member and pivotally displaceable thereby and a member on which said pivotally displaceable member is pivotally mounted on an axis about which the displaceable member pivots, and wherein said pivotally displaceable member is a lever handle movable relative to another member and forming tongs, and wherein said other member is another lever handle, with said inflatable thrust producing member being disposed between both said lever handles, and including resilient means connected to said lever handles for restoring the tongs to their initial open position.
Claim 3
Dependent Claim
10 words
Tool according to claim 1 wherein said tongs are pincer-formed.
Claim 4
Dependent Claim
16 words
Tool according to claim 1 wherein said inflatable member comprises a hose having pressure-tightly closed ends.
Claim 5
Dependent Claim
51 words
Tool according to claim 3 wherein said hose ends are closed by a cap respectively extending over said hose ends and by a respective corresponding elastic body received in the interior of said hose, said cap having a crimp therein form-locking both said cap and said elestic body with said hose.
Claim 6
Dependent Claim
15 words
Tool according to claim 1 wherein said inflatable member is formed of elastic profile material.
Claim 7
Dependent Claim
128 words
Tool comprising a force-producing device having at least one inflatable thrust producing member displaceable so as to apply a given force, a pivotally displaceable member engageable by said inflatable thrust producing member and pivotally displaceable thereby and a member on which said pivotally displaceable member is pivotally mounted on an axis about which the displaceable member pivots, said inflatable thrust producing member being disposed between said pivotally displaceable member and said mounted member, means for securely retaining said inflatable member in the tool and wherein said retaining means is a holder member, and including another member cooperating with said holder member for securing said inflatable member in the tool, one of said members comprising a pin and the other formed with an eye wherein said pin is receivable.
Claim 8
Dependent Claim
128 words
Tool comprising a force-producing device having at least one inflatable thrust producing member displaceable so as to apply a given force, a pivotally displaceable member engageable by said inflatable thrust producing member and pivotally displaceable thereby and a member on which said pivotally displaceable member is pivotally mounted on an axis about which the displaceable member pivots, said inflatable thrust producing member being disposed between said pivotally displaceable member and said mounted member, means for securely retaining said inflatable member in the tool and wherein said retaining means is a holder member, and including another member cooperating with said holder member for securing said inflatable member in the tool, one of said members comprising a pin and the other formed with an eye wherein said pin is receivable.
Claim 9
Dependent Claim
128 words
Tool comprising a force-producing device having at least one inflatable thrust producing member displaceable so as to apply a given force, a pivotally displaceable member engageable by said inflatable thrust producing member and pivotally displaceable thereby and a member on which said pivotally displaceable member is pivotally mounted on an axis about which the displaceable member pivots, said inflatable thrust producing member being disposed between said pivotally displaceable member and said mounted member, means for securely retaining said inflatable member in the tool, and wherein said retaining means is a holder member, and including another member cooperating with said holder member for securing said inflatable member in the tool, one of said members comprising a ledge and the other formed with a groove wherein said ledge is receivable.
Claim 10
Dependent Claim
128 words
Tool comprising a force-producing device having at least one inflatable thrust producing member displaceable so as to apply a given force, a pivotally displaceable member engageable by said inflatable thrust producing member and pivotally displaceable thereby and a member on which said pivotally displaceable member is pivotally mounted on an axis about which the displaceable member pivots, said inflatable thrust producing member being disposed between said pivotally displaceable member and said mounted member, means for securely retaining said inflatable member in the tool, and wherein said retaining means is a holder member, and including another member cooperating with said holder member for securing said inflatable member in the tool, one of said members comprising a ledge and the other formed with a groove wherein said ledge is receivable.
