Definitions
- the invention relates to a directional W tool with an elongated handle, which carries at least one of its two ends pivotable about a pivot axis, each having two torque transmission flanks head.
- the handle has a Kraftbeetzschungsflanke for introducing a force for generating a torque on the head. The farther the force applying edge is from the head, the greater the torque applied to the head with the same force.
- a screwing tool of the type described above is known from DE 94 04 031 Ul.
- a head having two torque transmitting flanks.
- Each of the two jaws forms a torque transmission edge.
- the two torque transmission flanks approach each other when a torque is applied to the head via the handle.
- a tooth arrangement of the end of the handle engages in a toothed rack arrangement of the movable jaw.
- the prior art further includes WO 2010/002239 A1.
- the invention is based on the object of further developing a screwing tool characterized at the outset in terms of use. [0008] The object is achieved by the invention specified in the claims, wherein the subclaims represent not only advantageous developments of the invention stated in the main claim but also independent solutions to the problem.
- a screwdriving tool in which a head pivotable about a pivot axis is arranged at each end of the handle.
- the handle forms two force loading flanks on which a force can be exerted to apply torque to the head remote from the force loading flank.
- this force application flank is adjacent to a nearby head.
- a narrow side of the head adjacent to the respective force application flank forms an extension of the force application flank.
- Each of the two heads is supported in a Schwenkend ein with a stop on a counter-attack of the handle. In the swivel end position
- the heads each form quasi-rigid extensions of the force-loading flank, which is subjected to force in order to apply torque to the respective other head.
- the narrow side of the head thus forms a pivotally associated with the handle lever extension, which preferably connects flush to the Kraftbeieryerungsflanke the handle.
- the handle has two opposite broad sides and two opposite narrow sides. Through the ends of the two broad sides extend the pivot axes, with which the head is articulated on the handle. One of the two narrow sides forms the Kraftbeaufyerungs- flank.
- Each of the two heads also forms two opposite broad sides.
- the broad sides of the two heads and the handle are preferably in parallel planes. In the broad side plane of the head against the handle is pivotally mounted.
- the head may have a fixed jaw and a movable jaw which is displaceable relative to the fixed jaw. The two jaws can form mutually facing torque transfer flanks.
- the two heads which are each pivotally connected to the handle at the end of the handle, preferably differ from one another in that their minimum distances between the torque transmission flanks in the two first pivot end positions are different from one another.
- the two heads are set up so that they each have hex nuts or screw heads with three or four different key widths. In that the minimum distances between the torque transmission flanks of the two heads are different from each other, the number of key widths to be screwed with the screwing tool can be doubled.
- the movable jaw is coupled for movement with one arm of the handle such that the distance of the two torque transmission flanks or the distance of the movable jaw from the fixed jaw changes when pivoting the head relative to the handle.
- the maximum distance between the two torque transmission edges of the one head may be less than the minimum distance between the two torque transmission edges of the other head.
- the second head of the screwing tool which can be grasped by the user's hand, forms a handle which represents a force introduction point which is at a maximum distance from the second head.
- the material thickness of the two jaws of the head is greater than the material thickness of the handle and in particular the narrow side of the head is wider than the trained from the narrow side of the handle Kraftbeetzyerungsflanke.
- FIG. 3 shows the screwing tool cut according to the line III-III in FIG.
- the screw shown in the drawings T ool has an elongated, steel-made handle 1.
- the handle 1 has a first end 1 'and this second opposite end 1 ".
- the first end 1' befin- to det a first Head 2, which is pivotable about a pivot axis 4 with respect to the handle 1.
- the head 2 has a fixed jaw 13 and a movable jaw 14 displaceable with respect to the fixed jaw 13.
- the fixed jaw 13 forms one on the movable jaw 14 directed torque transmission edge 15 and the movable jaw 14 of the torque transmission edge 15 opposite torque transmission edge 16 from.
- the movable jaw 14 forms with a tooth gap a pressure flange 18, on which a tooth-like arm 17 of the first end 1 'of the handle 1 engages.
- the movable jaw 14 is urged by a spring 12 on the fixed jaw 13.
- the spring 12 holds the head 2 in a first
- Pivot end position in which a stop 8 of the head 2 is supported on a counter-stop 9 of the handle. In this swivel end position, the S1 between the two torque transmission edges 15, 16 mini- mally.
- a second head 3 Secured to the second end 1 "of the handle 1 is a second head 3 which is pivotable about a pivot axis 5 relative to the handle 1.
- the second head 3 has a fixed jaw 13 and a movable movable relative to the fixed jaw 13 Jaw 14.
- the two jaws 13, 14 aufei- to each other to be directed torque transfer flanks 15, 16, which have a minimum distance S2 in a Schwenkend ein the head 3 relative to the handle 1, which is lower than that Distance Sl, so that with the first head 2 hexagonal profiles of a different width across flats than with the head 3 between the torque transmission flanks 15, 16 can be accommodated to apply a torque on screws or nuts.
- the movable jaw 14 of the second head 3 is acted upon by means of the spring 12, so that a stop 8 of the head 3 rests against a counter-stop 9 of the handle 1. Again, a movement coupling between the handle 1 and movable jaw 14 is provided, in which an arm 17 engages a pressure flank 18 of the head 3.
- the narrow sides of the handle 1 each form adjacent to one of the two heads 2, 3 Kraftbeetzleyungsflanken 6, 7 from.
- the Kraftbeetzleyungsflanken 6, 7 bulged slightly concave.
- a force is exerted on the respective force application flanks 6, 7 so that a torque can be exerted on the head 2, 3, which is arranged away from the respective force application flank 6, 7.
- the immediately adjacent head 2, 3 lying close to the force application flank 6, 7 forms, with its narrow side 11, an extension of the force application flank 6, 7.
- the extended Kraftbeaufyerungsflanke 6, 7 thus forms a formed of the narrow side 10, 11 supporting flank, which is flush, ie
- the two narrow sides 10, 11 join the force-loading flanks 6, 7 approximately in the same narrow side width, so that an enlarged pressure surface is formed which, upon actuation of the screwing tool from FIG Handball of the user's hand can be acted upon.
- the user can pick up one of the two heads 2, 3 in the hollow of the hand, the palm of the hand being supported on the narrow side 10, 11.
- the bending between the index finger and the thumb can lie in the convex force application flank 6, 7.
- the transition region between the extended Kraftbeaufschlagungsflanken formed by the head 2, 3 6, 7 substantially rectilinear in the trained by the handle Kraftbeaufschlagungs- flanks 6, 7 passes.
- the two surface sections of the adjoining force application flanks 6, 7 are located on the handle 1. as well as head 2, 3 flush with each other.
- the transition region between the side surface of the handle 1 and side surface of the head 2, 3 is formed on the side of Kraftbeaufschlagungsflanke 6, 7 no kink and no step.
- a screw T ool which is characterized in that
- a screwing tool which is characterized in that the head 2, 3 is held by means of a spring 12 in the pivot end position.
- a screwing tool which is characterized in that the two force application flanks 6, 7 are formed by the same narrow side of the handle 1.
- a screwing tool which is characterized by a fixed on the head 2, 3 fixed jaw 13 and a pivoting of the head it 2, 3 relative to the fixed jaw 13 displacing movable jaw fourteenth
- a screwing tool which is characterized in that the distance between a first torque transmission flank formed by the fixed jaw 13 and a second torque transmission flank 16 formed by the movable jaw 14 in the swivel end position is minimal.
