Embodiment Construction

[0025] The illustrated tongs 1 have two tong arms 2, 3 which can lie in a plane of rotation E (see especially figure 2 ) are connected to each other at a hinged joint 8 in a relatively rotatable manner.

[0026] Each tong arm 2 , 3 has a handle region G at which, in principle, a hand can be gripped on the tong arm for actuation.

[0027] A handle recess 4 , 5 or 6 , 7 each having a longitudinal length L is formed on both sides of the plane of rotation E and on the two clamp arms 2 , 3 . A handle recess 4 , 5 , 6 , 7 is preferably formed with a length dimension greater than its width dimension, in particular the length dimension is preferably 1.5 to 3 times the width dimension. The grip recesses 4 , 5 , 6 , 7 are arranged relative to the length of the grip region G in such a way that the grip region G of the tong arm protrudes at least the width of a finger on the side of the articulation region. In this example, the figure 1 The protrusion marked with the length section G1...

Abstract

The pliers (1) have two pliers journals (2,3) with a grip area and are connected with each other in a hinge area for pivoting in a pivot plane. Recessed grips (4,5) are formed at the pliers journals, possibly at a grip cover, in which the pliers journals are received. An extension of the grip area is given at the hinge area side of the recessed grips in the closed position of the pliers. The extension corresponds the finger width.

Description

technical field [0001] The invention relates to a tongs with two tong arms, wherein the tong arms each have a handle area and are connected to each other in an articulation area for rotation in a swivel plane, wherein also on the tong arms, Optionally, a handle recess is formed in each case on the handle sleeve which accommodates the tong arm. Background technique [0002] Various configurations of such clamps are known. For this, reference is made, for example, to European patents EP 228032A2 and EP 970781A2. [0003] In the known tongs, handle recesses are assigned to the respective one articulation-side end region of the handle region of the tong arms. Thus, when the tong arms are tightly closed together in the closed or almost closed state of the tongs, an advantageous support, in particular of the thumb, may also be achieved in an advantageous manner, possibly on both sides of the tong arms extending side by side. in the recess of the handle. [0004] On the other h...
