Description

Field of the Invention

[0001] The present invention relates to a pliers-like cutting tool having a first jaw and a second jaw, the first and second jaws being pivotally interconnected at a joint and having a gripping region respectively on one side of the joint and a working region respectively on the other side of the joint, wherein the jaws have substantially the same continuous thickness along their longitudinal extension in the portions where their working regions are formed, wherein the working region further forms a cutting edge and a clamping surface, and wherein the cutting edges interact in a cutting plane, and wherein the clamping surface is formed further away from the joint than the cutting edge, and wherein the jaws are also formed to extend through the cutting plane along the longitudinal extension to transition into a section forming the clamping surface, and wherein, with reference to a top view in the closed position of the jaws, in which the cutting plane is shown as a line, the jaws also extend through the cutting plane along the longitudinal extension in the case of a direction change in the central plane of the jaws, the central plane being linearly represented in this top view. Background Art

[0002] The aforementioned pliers-like cutting tool is known. For example, reference can be made to document DE 10 2005 008 328 A1. Thereby, a cutting tool that can be used in the field of electrical installation is known. Each working region of the cutting tool has a cutting edge and a clamping surface, which is formed in the free end region of the working region. In order to form the clamping surface, the free ends of the working regions are inclined in opposite directions, wherein each jaw having a working region at the end side partially penetrates the cutting plane while maintaining the thickness of the jaw. After this penetration region of the jaw, the free end of the jaw forming the clamping surface extends in the same direction as the jaw within the working region. The length of the clamping surface in the direction of the cutting plane is greater than the length or width of the lateral clamping surface of the clamping surface. Summary of the Invention

[0003] In view of the above prior art, the technical problem to be solved by the present invention is to further advantageously design a pliers-like cutting tool of the aforementioned type.

[0004] The first concept of the present invention with respect to the pliers-like cutting tool for solving the said technical problem lies in that it is hereby stipulated that the length formed by the clamping surface constituted by the two jaws perpendicular to the cutting plane is greater than the thickness of each jaw.

[0005] Since the length of the clamping surface as observed in its own direction is greater than the thickness of the jaw as observed perpendicular to the cutting plane, the operability of the tool is improved, for example, during the process of clamping and twisting two or more wires. The relevant length of the clamping surface can be, for example, 1.2 times or more of the jaw thickness, for example, about 1.5 to 2 times or more, for example, about 2.1 to 3 times.

[0006] Also preferably, the depth of the clamping surface in the longitudinally extending direction corresponds to the thickness of the jaw legs.

[0007] At least a part of the exposed clamping surface adjacent in the longitudinally extending direction of the jaw legs - starting from the joint towards the free end - which part of the clamping surface forms an end section of the jaw legs, preferably dimensionally matched in terms of thickness to the thickness of the rest of the jaw legs, especially in the region between the joint and the direction change, and its thickness is preferably equivalent to the depth of the clamping surface in the longitudinally extending direction especially in this end section. This can advantageously be achieved by the relevant end section of the bent jaw legs, for example when the jaw legs are constructed as stamped steel parts.

[0008] The central plane passing through the middle of the jaw legs with thickness can also be parallel to the working area, such as the cutting surface in the cutting edge area, and thus further aligned substantially in the longitudinally extending direction of the jaw legs.

[0009] Local sections of the central plane resulting from the direction change can, with reference to the top view, transition into each other with sharp edges in cases including right angles or acute angles, for example, but can also form an arc transition area from a local section of the central plane to an adjacent local section. Also, for example, such an arc transition area occurs when the deflection resulting from the direction change is formed by bending the jaw feet.

[0010] After the direction change, the local sections of the central plane or the central plane formed after bending can extend in a straight line and / or bend along an arc with reference to the top view.

[0011] If, with reference to the extending direction of the central plane in the top view, at the end of the uniform course (such as a straight line and / or at least approximately uniformly curved course) of a local section of the central plane, another local section passing through the cutting surface is adjacent, and this local section has a changed course of the central plane relative to it, then the direction of the central plane changes.

[0012] Other features of the present invention are described below, also in the description of the drawings and in the drawings, usually in their preferred assignment relationship with the solution or other features described in principle. However, these features can also have inventive significance when combined only with a single described feature or each of the other described features, or can also have independent inventive significance separately.

[0013] Therefore, according to a preferred design, the direction change can be achieved by the jaw legs straddling substantially perpendicular to the cutting surface with reference to the top view. The free end section of the jaw legs forming the clamping surface can accordingly extend substantially perpendicular to the rest of the jaw legs, for example, with reference to the top view of the closed position of the jaw legs, after the direction change.

[0014] Further preferably, after the (first) direction change, the jaw legs extend in opposite directions in the region of their free ends with reference to the top view, so that the two jaw legs bend through the cutting plane when bent, for example, around an imaginary axis that forms a point in the top view. In addition, with reference to the top view, the jaw leg ends forming the clamping surfaces preferably overlap in their respective longitudinal extension directions. According to the (first) direction change, the jaw legs preferably completely pass through the cutting plane. The jaw legs have two longitudinally extending edges, which are given according to the thickness of the jaw legs in the top view.

[0015] According to an improvement, the jaw legs can also pass through the cutting plane in the case of two direction changes in the longitudinal extension direction, namely the first direction change and the second direction change. Here, further preferably, each jaw leg can pass through the cutting plane in the region of the first direction change and also in the region of the second direction change, preferably completely passing through the cutting plane in the above sense. With reference to the top view perpendicular to the cutting plane, alternatively, it can also pass through the cutting plane at an acute angle of, for example, 30 to 60°, or also, for example, about 45°. Correspondingly, the free ends of the jaw legs can extend relative to the cutting plane on the side where the relevant jaw legs also extend, for example, in the region of their cutting edges. Due to the two direction changes, with reference to the top view, the first jaw leg extends from one side of the cutting plane to the other side of the cutting plane, while the second jaw leg extends on the other side of the cutting plane, that is, especially in the region of its cutting edge, and finally returns to the original side of the cutting plane. Thereby, a relatively large, overlapping clamping surface can be achieved.

[0016] Even if two direction changes are formed, in a further preferred embodiment, the two jaw legs still extend in opposite directions with reference to the top view. Therefore, in the direction perpendicular to the cutting plane, the lengths of the clamping surfaces of the two jaw legs are overlapped, which can be equivalent to 2 times or more than 2 times the thickness of the jaw legs, such as 3 times or 4 times or even 5 times or more than 5 times.

[0017] In a further preferred embodiment, each time the direction of the jaw legs changes, it is designed as a whole according to the occurring bend. Therefore, the jaw legs are designed as a whole according to the direction change occurring in the central plane. In addition, this method can also be preferably used in the case of only one direction change. The jaw legs preferably pass through the cutting plane over their entire width. Considering the perpendicular to their thickness, it is further preferred to substantially maintain the thickness of the jaw legs at the same time, and the thickness of the jaw legs also remains unchanged in the region of one or more direction changes.

[0018] The clamping legs can define a boundary of a given gap that overlaps with the cutting plane between a first-direction change and a second-direction change. Referring to the top view, the gap can also preferably occur on both sides of the pivot plane. The pivot plane passes through the continuous gap. This gap further preferably has the same shape on both sides of the pivot plane. In this regard, the gap can be divided into two ideal halves. Correspondingly, there is preferably a gap extending in the width direction of the clamping legs between the clamping legs. For example, this can be used to clamp a wire or the like, and can also be used, for example, to bend a wire inserted into the gap.

[0019] Preferably, this gap is completely surrounded by the clamping legs in the top view. This enables the boundary of the gap to be surrounded by the clamping legs with reference to the top view.

[0020] Also preferably, the clamping surface is provided with teeth. Here, it is also preferably possible to define the orientation of the teeth, wherein the edges of the teeth extending at intervals from each other in the transverse direction of their extension direction are oriented substantially perpendicular to the cutting plane. In addition, the toothed regions of each clamping leg can be transverse to the cutting plane once, multiple times, especially twice. Thus, the toothed regions can extend beyond the direction-change regions or the two direction-change regions and the free end sections of the respective clamping legs.

[0021] The ranges and value ranges or multiple ranges shown above and below also include all intermediate values in terms of the disclosure, especially at intervals of one tenth of each dimension, and can also be dimensionless where possible. For example, 1.2 to 2 times also includes the disclosure of 1.3 to 2 times, 1.2 to 1.9 times, 1.3 to 1.9 times, etc., and 30 to 60° also includes the disclosure of 30.1 to 60°, 30 to 59.9°, 30.1 to 59.9°, etc. The present disclosure serves to define the lower and / or upper boundaries of the ranges, but alternatively or additionally also relates to the disclosure of one or more individual values of each range.

[0037] Figure 1 Disclosed and described is a pliers-like cutting tool 1 having a first jaw leg 2 and a second jaw leg 3.

[0038] The two jaw legs 2 and 3 are pivotally interconnected with each other about a resulting geometric pivot axis x in a joint 5 formed by a joint pin 4. Starting from the joint 5, each jaw leg 2, 3 forms a gripping area 6 or 7 on one side of the joint 5 along the respective longitudinal extension direction L of the jaw leg, and forms a working area 8 or 9 on the other side of the joint 5.

[0039] The gripping areas 6, 7 and the working areas 8, 9 of the jaw legs 2 or 3 are integral and preferably constructed of a uniform material, preferably starting from a steel plate stamping. Also preferably, each of the working areas 8, 9 has a continuously identical thickness d when viewed in the direction of the pivot axis x, and this thickness is also preferably provided continuously in each of the gripping areas 6 or 7 and preferably in agreement with the thickness d of the working area. The entire jaw legs 2, 3 can be formed starting from a single stamping.

[0040] Starting from the joint 5 in the direction of the free ends 10, 11 of the working areas 8 and 9, the cutting tool 1 preferably first has a first cutting area 12, then preferably a second cutting area 13, and finally, on the first and / or second cutting areas 12, 13, a clamping area 14 forming a flat jaw area adjoins at the ends of the working areas 8 and 9, and this clamping area has clamping surfaces 15 and 16.

[0041] The first cutting area 12 consists of the cutting edges 17, 18 of the jaw legs 2 and 3. This first cutting area 12 is also preferably designed in the form of side cutters, for example for cutting electric wires or the like.

[0042] The cutting edges 17 and 18 interact on a cutting plane E extending perpendicular to the pivot axis x. In this cutting plane E, the facing flat inner surfaces 19 and 20 of the working areas 8 and 9 can at least substantially abut each other in the cutting areas 12 and 13, such that during the pivoting movement of the jaw legs 2 and 3 from Figure 4 the shown open jaw leg position to Figure 3 the shown closed jaw leg position, the cutting edges 17 and 18 can slide past each other in a scissor-like manner.

[0043] In the transition from the working area to the gripping area, a crank 21 or 22 can be provided in the direction of the cutting plane E, if necessary at least partially penetrating the cutting plane E. After the crank, the corresponding gripping area can extend freely outwards. Each of the gripping areas 6 and 7 is preferably provided with a gripping sleeve 23, 24.

[0044] The second cutting area 13 is preferably designed as a wire stripping area and preferably also has a plurality of cutting configurations, and if necessary each cutting configuration is formed by two interacting first cutting edges 25 and second cutting edges 26 which are correspondingly superimposed on the first jaw leg 2 or the second jaw leg 3. In order to visually and haptically subdivide the cutting configurations and quickly and intuitively find the cutting configurations important for wire stripping, even under low light conditions, for example, separating joints 27, 28 are also provided on the first jaw leg 2 and the second jaw leg 3, and these separating joints subdivide the cutting configurations into three groups as shown, for example, with two or one cutting configuration in each group. As Figure 3As shown in the closed position of the pliers, the separating joints 27 and 28 pass through the intermediate plane M which is perpendicular to the cutting plane E and accommodates the pivot axis x, and abut against the opposite flat inner surfaces 19 or 20 of the other plier leg.

[0045] Preferably, according to Figure 3 The closed position of the plier legs can also be the cutting tool locking position, in which the plier legs are locked to each other. For this purpose, a locking tongue 29 is provided which can rotate about a geometric axis y extending parallel to the pivot axis x. The locking tongue is rotatably mounted, for example, on a pin 30 fixed to the first plier leg 2. The locking tongue 29 can be rotated from the locking position to the release position by a tongue-shaped operating member 31 and can be rotated back, wherein in the locking position the locking projection 32 contacts a corresponding positioning and configured locking shoulder 33 of the other plier leg, here the second plier leg 3 (see Figure 3 ).

[0046] In addition, as Figure 3 shown, the plier legs 2 and 3 can move in the direction from the Figure 4 shown open position of the plier legs towards the closed position of the plier legs against the spring force. For this purpose, a cylindrical spring 34 can also be provided as shown, which is embedded in the window-shaped through holes 35 and 36 of the plier legs 2 and 3, and the through holes can be stacked in the direction of the pivot axis x. Due to the surrounding of the projections, the compression spring 34 is fixed at its ends to the projections 37, 38 of the plier legs 2 or 3, which projections extend into the corresponding through holes 35 or 36.

[0047] In order to form the clamping area 14, each plier leg 2, 3 preferably completely penetrates the cutting plane E in the region of its free ends 10, 11, wherein with reference to Figure 5 the top view of the closed position of the cutting tool 1 shown, in which the cutting plane E is represented as a line, when the direction of the central plane H1 of the plier leg 2 or the central plane H2 of the plier leg 3 changes, the plier leg 2 or 3 penetrates the cutting plane E, and in this top view the central plane H1 or the central plane H2 is linearly represented (also see Figure 9 ).

[0048] According to Figures 12 to 14 the second embodiment shown, when only a bend is formed by the change of direction (the first change of direction A1 of the first plier leg 2 and the first change of direction A1' of the second plier leg 3) on each plier leg 2 and 3, a right-angled change of direction of the orientation of the central plane H1 or H2 can be achieved, for example, with reference to the top view.

[0049] Here, the first central plane section H1' of the jaw 2 in the cutting regions 12 and 13 extends substantially parallel to the cutting plane E at the center of the jaw thickness d. In the present embodiment, after the central plane H1 passes through a transition section 44 of at least an approximate angle, a second central plane section H1'' appears in the region of the end section 39, with reference to Figure 14 The top view preferably forms a right angle with the first central plane section H1''. Therefore, the intersection angle α between the local section H1'' or the entire central plane H1 and the cutting plane E is preferably 90°. The central plane H2 of the jaw 3 extends equivalently and is mirror-imaged with respect to the extension direction of the central plane H1 of the jaw 2 with reference to the cutting plane E. In this top view, the cutting plane E is linear.

[0050] As Figure 14 shown, the mutually facing clamping surfaces 15 and 16 in the curved end sections 39 or 40 can be arranged to completely overlap in the vertical projection in the top view. This enables the length l of the clamping surfaces 15 and 16 to be perpendicular to the pivot plane E. In particular, the overlapping sections of the clamping surfaces 15 and 16, as long as these parts do not completely overlap, in the Figure 14 embodiment shown, the length l is approximately equal to twice the thickness d of the jaw 2 or 3.

[0051] Here preferably, the clamping surfaces 15 and 16 have teeth 41, 42, wherein each tooth is preferably in the direction perpendicular to the cutting plane E. For example, as can be seen from Figure 13 it is possible to form corresponding teeth 41, 42 in the direction of the clamping surfaces 15, 16 outwardly towards and up to the possible second cutting region 13 if necessary.

[0052] Figures 1 to 11 The embodiment shown in Figure 9 provides for two successive direction changes of the central plane H1 or H2 to form the clamping region 14. With particular reference to the detailed view in Figure 9 a first direction change Al or Al' occurs first after the second cutting region 13. Here, the jaws 2 and 3 respectively completely penetrate the cutting plane E, wherein, with reference to the

[0053] top view of Figure 14 the jaws 2 and 3 cross each other in the projection perpendicular to this plane.

[0054] Different from the embodiment shown in

[0055] After the first-direction change A1 or A1' of the first jaw 2 or 3, a second-direction change A2 or A2' of the central plane H1 or H2 follows. Due to the second-direction change, the end sections 39 or 40 of the jaws 2 or 3 are preferably oriented perpendicular to the cutting plane E and return to one side of the cutting plane E through the cutting plane E, where the relevant jaw extends additionally. Accordingly, the jaws facing the relevant free ends are shaped hook-like and penetrate the cutting plane E twice completely.

[0056] In the present embodiment, during the first-direction change A1 of the jaw 2, a rounded transition 44 is produced between a first central-plane section H1' of the jaw 2, which preferably extends substantially parallel to the cutting plane E, and an adjacent second central-plane section H1'' that penetrates the cutting plane E. For example, due to the bending of the relevant jaw area about a fictitious geometric axis z (or z' relative to the jaw 3) extending in the height direction of the jaw, the fictitious geometric axis is represented as a point in a top view. By the bending, a first bending section 46 is formed on one side of the jaw 2, as shown in the figure, followed by a straight section 47 that penetrates the cutting plane E at the above-mentioned acute angle α, for example 45°.

[0057] As shown in the figure, the second-direction change A2 of the same jaw 2 can also be achieved by a kink produced by the bending of the relevant jaw area about another fictitious geometric axis u (or u' relative to the jaw 3) that extends parallel to the fictitious axis z. By the bending, a second bending section 48 adjacent to the straight section 47 is produced, which can extend, for example, at an angle of about 135°, and preferably the overall orientation of the second bending section is opposite to the direction of the cutting plane E. Accordingly, the second-direction change A2 also produces a curved extension transition 45 of the central plane H1 between the second central-plane section H1'' and a third central-plane section H1''' that is the last connecting central-plane section of the straight-extending end section 39. In the top view, the third central-plane section H1''' preferably extends at an angle of 90° to the cutting plane E.

[0058] In the present embodiment, the central plane H2 of the jaw 3 also extends and, with reference to the straight cutting plane E in the top view, is mirror-symmetrical to the extension direction of the central plane H1 of the jaw 2. Accordingly, curved sections are also formed, and straight sections that penetrate the cutting plane E are formed between these curved sections.

[0059] Especially from Figure 9It can further be seen that the imaginary axes u and u' of the second bending section are substantially coincident in the regions of the second directional changes A2 and A2' of the central planes H1 and H2, and can further extend substantially in the cutting plane E in the closed position of the jaws. Thus, between the corresponding first and second directional changes, the jaws 2 and 3 can further delimit, substantially in the region of the second bending section, the boundary of a gap 43 that overlaps the cutting plane E, and preferably completely encloses the gap 43. The gap 43 can also preferably extend approximately concentrically with the imaginary axis u or u'.

[0060] The length l of the clamping surfaces 15 and 16, which are formed in the end sections 39 and 40 and are substantially coincident in the vertical projection, can be approximately 2.5 to 3 times the thickness d of the jaws. Viewed in the longitudinal extension direction L of the jaws 2 and 3, the depth t of the clamping surfaces 15 or 16 in the region of the inclined end sections 39 or 40 corresponds to the thickness d of the respective jaws 2 or 3.

[0061] The above-described embodiments are used to illustrate the invention as a whole included in the application, which invention extends the prior art independently at least by the following combinations of features, wherein two, several or all of the feature combinations can also be combined with each other, namely:
