Run-through shears
In order for run-through shears in the case of which the user's hand is located at a distance from the workpiece during cutting, comprising a shears head which is formed by a first shears-head limb with a first cutting blade and by a second shears-head limb with a second cutting blade, also comprising a first handle part and a second handle part, a first handle-part/shears-head-limb combination and a second handle-part/shears-head-limb combination being formed and at least one handle part being disposed in an angled manner relative to the shears head, and further comprising a rotary bearing for pivoting the handle-part/shears-head-limb combinations relative to one another, to be improved such that they can be produced cost-effectively and have a low weight, it is provided that the cutting blades are individual parts which are fixed on cutting-blade retaining regions of the associated shears-head limbs, and that the parts forming the cutting blades are spaced away from the rotary bearing.
1 . Run-through shears in the case of which the user's hand is located at a distance from the workpiece during cutting, comprising:
a shears head which is formed by a first shears-head limb with a first cutting blade and by a second shears-head limb with a second cutting blade;
a first handle part and a second handle part;
wherein a first handle-part/shears-head-limb combination and a second handle-part/shears-head-limb combination are formed; and
wherein at least one handle part is disposed in an angled manner relative to the shears head; and
a rotary bearing for pivoting the handle-part/shears-head-limb combinations relative to one another;
wherein the cutting blades are individual parts which are fixed on cutting-blade retaining regions of the associated shears-head limbs, and the parts forming the cutting blades are spaced away from the rotary bearing.
2 . Run-through shears according to claim 1 , wherein the sliding surfaces of the rotary bearing are located outside the parts forming the cutting blades.
3 . Run-through shears according to claim 1 , wherein a sliding surface of the rotary bearing, said sliding surface being formed on the associated handle-part/shears-head-limb combination, is formed outside the associated cutting-blade retaining region.
4 . Run-through shears according to claim 1 , wherein the cutting blades are made of metal.
5 . Run-through shears according to claim 1 , wherein the handle parts are produced from a plastics material.
6 . Run-through shears according to claim 1 , wherein the shears-head limbs are produced from a plastics material.
7 . Run-through shears according to claim 1 , wherein the first handle-part/shears-head-limb combination is formed in one piece.
8 . Run-through shears according to claim 1 , wherein the second handle-part/shears-head-limb combination is formed in one piece.
9 . Run-through shears according to claim 1 , wherein the shears head has one or more guiding surfaces for spaced-apart guidance of cut material past the rotary bearing.
10 . Run-through shears according to claim 9 , wherein the first shears-head limb has a guiding surface for cut material.
11 . Run-through shears according to claim 9 , wherein the second shears-head limb has a guiding surface for cut material.
12 . Run-through shears according to claim 9 , wherein the guiding surface or guiding surfaces is or are spaced away from the rotary bearing in a height direction.
13 . Run-through shears according to claim 9 , wherein a guiding surface extends in the direction along a cutting edge of the associated cutting blade and in a direction which is at least approximately parallel to the axis of rotation of the rotary bearing.
14 . Run-through shears according to claim 9 , wherein a guiding surface extends laterally outward on a shears-head limb, in the direction away from the associated cutting blade.
15 . Run-through shears according to claim 9 , wherein a cutting blade projects beyond the associated guiding surface.
16 . Run-through shears according to claim 1 , wherein the rotary bearing is disposed in an extension of the first cutting blade in a direction away from a distal end.
17 . Run-through shears according to claim 1 , wherein the first handle-part/shears-head-limb combination has a recess in which the second handle-part/shears-head-limb combination is disposed in a rotatable manner.
18 . Run-through shears according to claim 17 , wherein the recess is bounded toward one side by the cutting-blade retaining region of the first shears-head limb.
19 . Run-through shears according to claim 18 , wherein the recess is bounded toward the other side by the first handle part.
20 . Run-through shears according to claim 17 , wherein the recess provides a blocking surface which limits the extent to which the shears head opens.
21 . Run-through shears according to claim 17 , wherein a depth direction of the recess is parallel to the axis of rotation.
22 . Run-through shears according to claim 1 , wherein a bearing recess with a sliding surface is formed on one handle-part/shears-head-limb combination, and a shaft stub with an associated sliding surface is seated in a rotationally fixed manner on the other handle-part/shears-head-limb combination.
23 . Run-through shears according to claim 1 , wherein the cutting blades are fixed on the associated shears-head limb via one or more fastening elements.
24 . Run-through shears according to claim 23 , wherein the fastening elements are positively locking elements.
25 . Run-through shears according to claim 23 , wherein cutting blades are fixed in from their surface.
26 . Run-through shears according to claim 1 , wherein, in the case of the second handle-part/shears-head-limb combination, the second handle part, or an element connected to the second handle part, is connected substantially at right angles to the second shears-head limb.
27 . Run-through shears according to claim 1 , wherein a compression spring is disposed between the two handle-part/shears-head-limb combinations, said spring opening in the non-loaded state the shears head.
28 . Run-through shears according to claim 1 , wherein a locking device, by means of which a closed position of the shears head can be fixed, is provided.
