Abstract

A manually operable pliers tool has first and second pressing jaws pivotally connected about a first pivot axis. A first handle extends from the first pressing jaw and a second handle is linked to the second pressing jaw. The second pressing jaw has a u-shaped node element with a base mounted on the first pressing jaw via the first pivot axis and a first limb mounted on the second handle via a second pivot axis. A stop, which is adjustable between a passive position and an active position, is arranged on the first pressing jaw, wherein opening movement of the second handle can be limited by a second limb of the node element coming to a stop on the stop by setting the stop into the active position.

First claim

What is claimed is:

1. A manually operable pliers tool, comprising
a first pressing jaw having a first handle extending therefrom;
a second pressing jaw pivotably mounted on said first pressing jaw about a first pivot axis;
a second handle which can move in a spreadable manner relative to said first handle and which is linked to said second pressing jaw; said second pressing jaw having a u-shaped node element having a base and two limbs extending from said base in the direction of said first and second handles, said base being mounted on said first pressing jaw via the first pivot axis and a first of said limbs being mounted on said second handle via a second pivot axis, sections of said pressing jaws remote from said handles forming a pliers mouth which when opened, pivots a second limb of said node element in the direction of an upper outer rim of said first pressing jaw, said outer rim being remote from said second pressing jaw; and
a stop adjustable between a passive position and at least one active position is arranged on the first pressing jaw, opening movement of said second handle being limited by said second limb of said node element coming to a stop on said stop by setting said stop into the at least one active position, said stop further limiting maximum opening movement of said second handle when said stop is placed in the passive position.

2. The pliers tool as defined in claim 1 , wherein said stop is pivotable about a third pivot axis between the passive position and the at least one active position.

3. The pliers tool as defined in claim 2 , wherein said stop includes an operating member for manually adjusting said stop between the passive position and the at least one active position.

4. The pliers tool as defined in claim 3 , wherein said operating member of said stop protrudes over said outer rim of said first pressing jaw.

5. The pliers tool as defined in claim 1 , wherein said stop has at least one first stopping edge, which, when said stop is positioned into the active position, prevents an opening movement of said second handle into a maximum opening position by limiting a pivot path of said node element.

6. The pliers tool as defined in claim 5 , wherein said stop has several a plurality of edges, which, when said stop is positioned in the active position, enable an opening movement of said second handle only to respective limited opening positions which are smaller than the maximum opening position of said second handle.

7. The pliers tool as defined in claim 6 , wherein said stop has a further stopping edge, which, when said stop is positioned in the passive position, abuts said node element when said second handle is in the maximum opening position.
