Definitions

  • the invention relates to pliers with two pliers legs, which are connected to one another by means of a hinge pin having an actuating end in the form of an articulated bolt head, the pliers mouth being formed above the crossing region and grip sections on the pliers legs below the crossing region, the one for changing the size of the Forceps jaws in the intersection area relative to the other forceps leg, gradually adjustable forceps legs penetrate a free space of the other forceps leg, further the hinge pin is guided in a bore in the other forceps leg and can be displaced transversely to the lengthwise plane of the forceps and has two cross-sectional areas adjacent to one another in the axial direction of the joint pin, one of which is coupled in the coupled Condition in positive engagement with the profiled flanks of a longitudinal slot of one pliers limb lying in the intersection area and the other cross-sectional area freely in the longitudinal leg litz is movable.
  • Such a pair of pliers is known from EP-A-0 116 305, the hinge pin being composed of a profiled cross-sectional area for positive engagement in correspondingly shaped flanks of a pliers leg and of a substantially thinner cross-sectional area. At its end, the thinner cross-sectional area is formed with a stop collar which, when the hinge pin is actuated in the axial direction, acts on an outside of another pliers leg facing it.
  • pliers according to US Pat. No. 1,885,895 are known in the prior art.
  • the hinge pin of this known Pliers can be operated from both sides. However, only on one of the actuation sides is there a surface recess in the pliers leg. The diameter of this recess corresponds to the diameter of the joint bolt head. The depth of the recess is also only limited to the fact that the actuating end of the hinge pin can retract a little in this recess, but in the actuated state also protrudes beyond the surrounding surface of the pliers leg.
  • the invention is concerned with the technical problem of making pliers as stated at the outset more favorable in terms of handling.
  • a pair of pliers with a particularly high utility value.
  • the thumb is supported and held in the recess when actuated.
  • an actuating stop which is recessed in depth is provided for the joint bolt head.
  • the procedure here is that the free space for pushing through the pliers leg has a recess arranged on the actuating side of the hinge pin, which receives the hinge pin head when the hinge pin is actuated, and that a recessed actuation stop is provided for the hinge pin head.
  • the structural means are simple and functional. It is particularly advantageous that the pivot pin head occurs when actuated below the level of the pliers leg side having the recess.
  • the joint pin head In the basic position, the joint pin head only slightly extends beyond the plane of the pliers leg side having the recess, which makes it easier to feel the joint pin head.
  • the profiled flanks of the one leg of the pliers are designed as a stop.
  • a spring loading of the hinge pin from the side opposite the hinge pin head proves to be particularly advantageous, with which the hinge pin is always shifted back into its basic position after adjustment of the jaw opening. There is thus always a positive connection between the hinge pin and the pliers leg having the profiled flanks in the basic position.
  • the arrangement can also be so be met that the hinge pin is adjustably fixable by means of a locking part acting essentially perpendicular to its direction of displacement, whereby the basic position of the hinge pin is defined.
  • a displacement of the hinge pin for the purpose of changing the pliers jaw width thus takes place against the action of a locking part, which can be provided in the region of the pliers leg having the recess.
  • a relocation of the hinge pin takes place here willingly, the latter being manually moved back until it is fixed by the locking part.
  • the latching part is advantageously designed as a spring-loaded ball which engages in a corresponding recess in the hinge pin.
  • the hinge pin has an intermediate section between the positive-locking cross-sectional area and the hinge pin head, the intermediate section having a constant cross section. The cross section of the intermediate section preferably corresponds to the clear width between the profiled flanks of the one leg of the pliers.
  • the hinge pin head is circumferentially substantially coincident with an annular envelope surface of the hinge pin, which has the consequence that the hinge pin, regardless of its operating position, is securely supported in the axial bores of the fork ends of the other pliers leg.
  • the recess arranged on the actuation side of the other pliers leg is funnel-shaped, this recess merging into the area of the axial bore. This configuration enables the hinge pin to be displaced in terms of handling in a release position, in order to change the clear width of the pliers mouth.
  • the recess eccentrically to the joint pin head, with which the recess has an ergonomically more favorable shape that results in improved handling when the joint pin is displaced.
  • the recess has a thumb size.
  • the latter can also be slightly oval and, as already mentioned, eccentric to the hinge pin. This enables the thumb underside to roll off optimally when the hinge pin is moved.
  • the hinge pin head is structured on the upper side. The latter is designed to be more grippy due to the above-mentioned measure and is therefore favorable in terms of handling.
  • the joint pin head can also be designed as a round button part which is spherically curved upwards.
  • the joint pin head essentially completely fills the opening in the recess in the depressed state.
  • the joint pin head thus has a diameter corresponding to the opening in the recess.
  • the hinge pin head is designed separately, which is advantageously realized in that the hinge pin head is screwed onto the hinge pin base body. Another pin connection can also be provided.
  • the recess provided in the other pliers leg has such a free diameter, or the joint pin head is designed with such a dimension in relation to the free diameter of the recess that a viewing gap is present even when the joint pin head is depressed remains on the profiled flanks of one leg of the pliers.
  • This measure proves to be advantageous, for example, if soiling occurs in the area of the profiled flanks of the one leg of the pliers. The contamination can practically not prevent the actuating head from being completely depressed. They are either pushed into the spaces between the tooth profiles, which open when the hinge pin head is pressed down, or between the edge of the hinge pin head and the edge of the surrounding recess.
  • the pivot pin head in the projection in the area of its largest diameter covers a tooth of the flanks of the pliers leg to about half a tooth depth.
  • the contact area of the joint pin head on the upper transverse surface of the tooth profile, which forms the stop for the joint pin head when pressed down, is thus kept very small. This is conducive to the removal of dirt in the sense described above.
  • the pivot pin head is formed in its base from the overlay of a rounded and rectangular surface, such that the width of the rectangle corresponds approximately to the free distance between the tooth flanks, but its longitudinal extent exceeds the diameter of the rounded surface.
  • the section of the hinge pin or the hinge pin head which corresponds to the rectangular area, extends only within the free area between the tooth flanks of the one leg of the pliers.
  • the rounded or circular surface is formed by the part of the hinge pin, which also forms the protrusion with respect to the tooth profile on the tooth flanks, which produces the abovementioned stop when depressed.
  • the narrow side of the rectangular surface is also preferably rounded. These narrow sides interact directly with the other pliers leg, in which the recess is formed. For this purpose, it is expedient that the radius of the circumferential line of the narrow sides corresponds approximately to the radius of the recess.
  • a protrusion of the rectangular area over the circular area in profile - ie in height - the adjacent circular section of the Joint head surpasses.
  • the pliers 1 have two mutually intersecting pliers legs 2 and 3. The latter are connected to one another in an articulated manner in the region of intersection by means of a hinge pin 4.
  • the pliers legs 2 and 3 each form a grip section 7 and 8 on the side above and below.
  • the joint of the pliers jaw M is at an angle of approximately 45 ° to the handle sections 7, 8.
  • the pliers leg 2 passes through a free space F of the pliers leg 3 corresponding to its thickness.
  • the free space F is designed as a slot lying in the leg pivot plane, which has two on both sides has longitudinal sides 9 of equal thickness. The latter are of greater width than that of the handle section.
  • the penetrating pliers leg 2 also has a width in the area of the free space F that clearly exceeds the width of the grip section 7. This passage area is designated 10. It is approximately at right angles to the jaw 5.
  • the pincer leg 3 which is passed through can be adjusted in stages.
  • the corresponding adjustment device consists of a longitudinal slot 11 penetrated by the hinge pin 4 in the penetrating pliers leg 2.
  • the longitudinal slot 11 is profiled on its longitudinal slot flanks 12 running parallel to one another. It is a sawtooth-like profile.
  • the individual tooth gaps are designated by 13 and, like the hinge pin 4, extend transversely to the pivot actuation plane of the pliers legs 2, 3.
  • the joint pin 4, which is guided in a bore 14 which is congruent with the longitudinal slot 11, is designed to be essentially rotationally symmetrical, viewed axially.
  • the hinge pin 4 is composed of a cylindrically shaped hinge pin head 15 and a hinge pin base part 16, the hinge pin head 15 being firmly connected to the hinge pin base part 16 by means of a screw 17. Both parts have essentially the same diameter.
  • the hinge pin base 16 is symmetrically flattened on diametrically opposite sides, this area a being delimited on the one hand by the hinge pin head 15 and on the other hand by a hinge pin collar 18 of the hinge pin base 16.
  • the thickness of the base part 16 of the hinge pin in the region a corresponds to the clear distance y of the longitudinal slot 11 between the longitudinal slot flanks 12, the length of the region a roughly corresponding to the addition of the width of the passage region 10 of the pliers leg 2 and a leg longitudinal wall 9 of the pliers leg 3.
  • two teeth 21 extending from the hinge pin collar 18 are formed on the flattened sides 19, 20 for positive engagement in the tooth gaps 13 of both longitudinal slot flanks 12.
  • the length of the teeth 21 corresponds approximately to three quarters of the width x of the longitudinal slot flanks 12.
  • the cross-sectional area a of the hinge pin base part 16 designed in this way thus serves on the one hand to achieve the positive connection between the hinge pin 4 and the pliers leg 2 and on the other hand when the hinge pin 4 is displaced in the direction z to secure the hinge pin 4 against self-rotation.
  • a recess 22 extending from the bore 14 is arranged in the longitudinal leg wall 9 of the tong leg 3.
  • This recess 22 is realized in the form of a countersink, leaving a remaining section of the bore 14.
  • the recess 22 is therefore circular.
  • the hinge pin 4 is under spring load, that is to say in order to maintain the positive engagement of the profiles.
  • the hinge pin 4 is acted upon by a leaf spring 23 from the free end having a full cross section.
  • the latter is located on the outside of the longitudinal leg wall 9 there.
  • the area of assignment of the leaf spring 23 has a groove 24 corresponding to its shape for its recessed assignment.
  • the leaf spring 23 takes a course adapted to the pliers leg 3, the end region of the leaf spring 23 being angled in the direction of the hinge pin 4.
  • the free end of the leaf spring 23 engages over a sector-shaped recess 25 on the end face of the hinge pin 4.
  • the sector shape takes into account the swivel angle requirement of the pliers legs 2, 3, taking into account the fact that the hinge pin 4 is also non-rotatable in the uncoupled state Longitudinal slot 11 carrying pliers legs 2 is held. A relative movement, that is to say a rotary movement of the hinge pin 4, only takes place in relation to the pliers leg 3 which is penetrated. A screw 26 or another fastening element which penetrates the other end is used to fix the leaf spring 23.
  • the jacket wall of the joint pin head 15 assumes support and guidance within the bore 14 of the right-hand side longitudinal wall 9 and the jacket wall sections 16 'support and guidance on the bore wall of the other side. This ensures that the hinge pin 4 is tilt-proof in any position.
  • the handling of the pliers is as follows: To cancel the mouth width previously used, it is only necessary to move the hinge pin 4 axially from the side having the hinge pin head 15, that is to say transversely to the plane of movement of the pliers legs 2, 3 against spring action.
  • the pivot pin head 15 is received by the recess 22 and with the impact of the pivot pin head 15 on the profiled longitudinal slot flanks 12 (the upper end face) of the longitudinal slot 11, the positive engagement between the teeth 21 of the pivot pin 4 and the tooth spaces 13 of the longitudinal slot 11 is canceled.
  • the hinge pin 4 can now be moved together with the pliers limb 3 displacing it in the direction of extension of the longitudinal slot 11.
  • the spring 23 brings about the desired positive engagement of the profiles, the pivot pin collar 18 serves as a stop on the longitudinal slot flanks 12.
  • FIGS. 8 to 11 Another embodiment of the hinge pin is illustrated with reference to FIGS. 8 to 11. Insofar as the same parts are not explained separately, reference is made to the above statements.
  • the recess 22 or more precisely its smallest diameter d is selected such that when the hinge pin 4 is depressed, a viewing gap s (see also FIG. 9) on the profiled longitudinal slot flanks 12 remains.
  • d in the case of a circular design, as in the exemplary embodiment
  • a viewing gap s see also FIG. 9 on the profiled longitudinal slot flanks 12 remains.
  • the button part 27 covers a tooth of the longitudinal slot flanks 12 approximately half the tooth depth in the projection in the region of its largest diameter d 1.
  • the articulated bolt head 15 consists in its base area of the superimposition of a rounded and a rectangular area.
  • the rounded surface is formed by the separate button part 27.
  • the overlay is further such that the width of the rectangle approximately corresponds to the free distance y between the longitudinal slot flanks 12, but the longitudinal extent exceeds the diameter d1 of the button part 27.
  • the narrow sides 30, 31 of the joint pin head 15 are rounded.
  • the rounding corresponds to the inner free rounding of the recess 22.
  • the recess 22 is composed in detail of a cone section 32, which has an angle of inclination of approximately 30 °, and a cylindrical section 33.
  • the narrow sides 30, 31 are raised such that they are in any case in the edge region in profile, i.e. in terms of height, exceed the adjoining edge region 34 of the button part 27, protrusion U 1.
  • the button part 27 is arranged sunk in the hinge pin 4 with respect to the narrow sides 30, 31. In the depressed position which is also shown in FIG. 10, it is clear that this projection U 1 prevents the hinge pin 15 or an edge region 34 of the button part 27 from being pushed under the bore 14 of the pliers leg 9 when it is moved.
  • the intermediate section Z between the positive cross-sectional area (teeth 21) and the joint pin head 15 with a constant cross section even continues in the area of the button part 27 and at least partially projects beyond it, namely to the Narrow sides 30 and 31.
  • FIG. 12 A modification is shown in FIG. 12 with regard to the recess 22 which surrounds the button part 27.
  • the recess 22 is designed so that an elliptical edge line 35 results.
  • the ellipse is irregular insofar as the focal points are generated by circles of different sizes and the ellipse in the lower area here resembles a parabola, in the upper area essentially an exact semicircle.
  • the button part 27 is arranged concentrically with a focal point or a center point of the semicircle line 35 a.
  • the boundary line 35 is also not pronounced in the area of the strongest curvature of the parabola, due to a penetration with an elongated hole 36 in the pliers leg 3.
  • the recess 37 of the embodiment of the pliers 1 shown in FIG. 15 is of exactly circular design, the center point AM being arranged eccentrically to the center point GM of the hinge pin 4.
  • the recess 37 offers an optimal support for the underside of the thumb when the pivot pin 4 is displaced.
  • the recess 37 in an elliptical shape (similar to the recess shown in FIG. 12), the upper region of the ellipse being arranged concentrically to the center point GM of the hinge pin 4.
  • the joint pin head 38 is designed as a round button part 39 which is spherically curved upwards.
  • the recess 22 is composed of a conical section 32 and a cylindrical section 33.
  • the articulation pin head 38 in the depressed state essentially completely fills the cylindrical section 33 of the recess 22 in its projection.
  • FIGS. 18 and 19 A modification is shown in FIGS. 18 and 19 with regard to the design of the joint pin head 40 and the recess 22 which surrounds the joint pin 4.
  • the recess 22 has a cone section 32 and a cylindrical section 33, but the cone section 32 has an inclination angle of approximately 60 °.
  • the joint pin head 40 is designed as a head part 41 structured on the upper side. This structuring is composed of a plurality of circular sections arranged concentrically and offset in height from one another, so that a step pyramid-shaped surface of the head part 41 is formed.
  • This design of the head part 41 serves primarily for the safe handling of the pliers 1 when the jaw width changes. Slipping of the thumb with a dirty joint pin head 40 is thus successfully counteracted.
  • the profiled flanks 12 form a limit stop for the joint pin 4 to be actuated, which is supported with the underside of the joint pin head 38 or 40 on the longitudinal slot flanks 12 mentioned.
  • FIGS. 20 and 21 an embodiment is shown in which the hinge pin 4 has none of the hinge pin heads mentioned.

  • FIGS. 22-24 show an alternative to this.
  • the hinge pin 4 can be fixed by means of a latching part 42 acting perpendicular to the direction of displacement of the hinge pin 4.
  • This locking part 42 is composed essentially of a compression spring 43 and a locking ball 44.
  • the compression spring 43 is in this case mounted in the longitudinal leg wall 9 opposite the recess 22 in a blind bore 45 which is open in the direction of the bore 14 and loads the ball 44 in the direction of the cylindrical end section of the pivot pin 4.
  • the pivot pin 4 is in this area with a corresponding Provide recess 46 for entry of ball 44 in the basic position.
  • the basic position of the hinge pin 4 is thus clearly defined. An unintentional release of the positive connection between the teeth 21 of the hinge pin 4 and the profiled longitudinal slot flanks 12 is hereby successfully counteracted.
