Definitions

  • the invention relates to a hand lever with a fastening element for a spindle, axle or the like, the hand lever and the fastening element being axially non-rotatably coupled in the longitudinal direction of the lever axis of rotation by means of two coupling elements, and the hand lever made of a softer material than that made of metal Fastening element is made and the hand lever-side coupling element consists of metal and is anchored in the material of the hand lever in a rotationally fixed manner, coupling members of the hand lever-side coupling element being able to be coupled to coupling counter-members of the fastening element-side coupling element.
  • a hand lever with fastening element is known from DE-B-1 278 860.
  • the coupling is designed as a snap-in coupling and is located inside the spindle, which is equipped with a central blind hole. Because this hand lever is rotationally symmetrical, special alignment in the direction of rotation with respect to the axis or the like need not be taken into account. In theory, due to the special design of the locking coupling connection, there are two mounting options offset by 180 °.
  • a hand lever in particular provided with a radially projecting handle, has to assume a predetermined position before the start of the rotation or possibly also after a certain partial rotation with respect to the spindle, axis or the like.
  • a preferred field of application are clamping levers, such as those used in technology, in particular in connection with machine tools, or clamping devices for holding workpieces which are to be machined on such machine tools.
  • Another hand lever with fastening element has become known from CH-A-309 659, which allows the hand lever to be moved relative to the spindle or axis by small angles of rotation.
  • a hand lever-side coupling element is inserted into a hole in the hand lever and is therefore not held in a rotationally fixed manner in the direction of rotation. Due to the thin walls of this sleeve and the displaceable mounting of the fastener located therein, a tight press fit with a corresponding frictional force is out of the question.
  • the external support of the spring for the axially loaded coupling is also problematic there.
  • the object of the invention is to develop a hand lever with a fastener according to the preamble of claim 1 so that it is possible to move the hand lever relative to the fastener by small angles of rotation, the coupling of both parts should be robust while securely holding the two coupling elements on the hand lever on the one hand and on the fastener on the other.
  • the hand lever with fastening element is designed according to the preamble of claim 1 in accordance with the characterizing part of this claim. Because the coupling members are formed in a manner known per se by an internal and an external toothing, the hand lever can be displaced in relation to the fastening element by small angles of rotation in accordance with the tooth pitch. The spring loading of the axial coupling ensures that it locks into place after adjustment. The spring force is safely transmitted to the fastening element on the one hand and the coupling element of the hand lever on the other hand.
  • the coupling element on the hand lever side is securely anchored in the comparatively softer material of the hand lever due to the anchoring elements, so that, for example, when using this hand lever as a tensioning lever, the necessary manual force can also be safely released.
  • the use of metal for the two coupling elements makes it possible to transmit the force in a deformation-resistant manner within the usual loads of such a hand lever.
  • the clutch disengages in the axial direction of the fastening element with simultaneous tensioning of the helical compression spring. After releasing the hand lever and preceding relative rotation with respect to the fastening element, your force then ensures that the coupling engages.
  • plastic for the hand lever gives the usual known advantages, in particular the low weight and the low manufacturing price. There is also no need for surface finishing and, if necessary, processing.
  • the shape and size of the anchoring elements depends not least on the material of the hand lever and the type of fastening on the hand lever side Coupling element in the material of the hand lever.
  • the hand lever-side coupling element is expediently extrusion-coated with the plastic of the hand lever. It goes without saying that the clutch teeth are kept free, so that reworking is not necessary at this point.
  • the formation of the coupling via an internal toothing and an external toothing leads to teeth of maximum size and thus to a heavy-duty tooth connection.
  • the support member for the spring element remote from the fastening element can be, for example, a screw, the underside of the head of which forms the support surface for the compression spring which is advantageously designed as a compression coil spring. This allows the unit to be assembled in a particularly simple manner.
  • the axial relative movement between the hand lever and the fastening element can be limited in that the spring is in a block position after a predetermined pressure movement of the hand lever.
  • the anchoring elements of the coupling element on the hand lever side consist of pins, warts or the like which protrude evenly on the outer circumference.
  • “on the outer circumference” does not mean that the pins or the like have to protrude in the radial direction, rather, in particular in the exemplary embodiment of the invention, a protrusion in the axial direction from the ring surface in question is provided.
  • a further embodiment of the invention consists in that the coupling counter-members of the fastening element-side coupling element are formed by the teeth of a pinion with external toothing attached, in particular molded, to the inner end of the fastening element, the teeth of the coupling members and coupling counter-members being able to be engaged and disengaged in the tooth longitudinal direction are and the clutch is spring-loaded axially in the snap-in direction Due to the spring load, the hand lever and the fastening element are always non-rotatably coupled, so that when the fastening element is connected to a spindle, axis or the like in a rotationally fixed manner, turning the hand lever or rotating the spindle or. The like causes.
  • the hand lever If, however, the hand lever is to be displaced in the direction of rotation relative to the current position of the spindle or the like, it is lifted against the fastening element, for example upwards, against the resistance, and is rotated by the intended angle of rotation.
  • the teeth only allow a gradual shift. However, this is without disadvantage in most applications.
  • the fastening element is designed as a sleeve or cup-shaped element with an inner pot base, which is mounted so as to be longitudinally displaceable and rotatable in a sleeve-shaped extension of the hand lever.
  • a central nut thread can be provided in the pot base for screwing in the screw.
  • the screw expediently has a thread only over part of its shank, so that the screw-in depth can be determined over the length of the threaded part.
  • the hand lever 1 consists of a material of comparatively low hardness, in particular of plastic. At its end facing the fastening element 2, it has a sleeve-like shape, which is followed by a handle piece with a U-shaped cross section. The free end has slightly longer U flanks and it is reinforced by an intermediate wall 3.
  • the fastening element 2, as shown in particular in FIG. 1, has an essentially sleeve-like shape. It has a nut thread 4 at its outer end and a nut thread 5 at its inner end. The latter is considerably shorter and smaller in diameter than the nut thread 4. It receives the threaded shaft part 6 of a screw 7.
  • the threadless shaft part 8 is surrounded by a conical helical compression spring 9. Its smaller end is supported on the underside of the screw head 10, while the larger spring end rests on the facing annular surface of a coupling element 11 on the lever side.
  • hand lever-side coupling element 11 which is shown in detail, is embedded in the material or plastic of the hand lever 1 or of the sleeve-shaped hand lever part 12 or is partially extrusion-coated with the plastic.
  • the coupling element 11 On its side facing away from the fastening element (2), the coupling element 11 carries, in particular, evenly distributed peg-shaped or wart-shaped anchoring elements 13 on the circumference, which serve for anchoring in the plastic material Molded teeth.
  • the latter accordingly extend parallel to the axis 16 of a spindle 17 or the like to be connected to the fastening element 2 and they form coupling counter-elements.
  • the fastening element 2 is on the upwardly projecting spindle end screwed on its mother thread 4.
  • a coupling element 18 on the fastening element side is molded onto the inserted, inner end of the fastening element 2 pointing upwards. It has the shape of a pinion with external teeth. The teeth 19 of this pinion correspond in shape, size and pitch to those of the ring gear 14.
  • the pinion and the ring gear are in engagement with one another due to the force of the compression spring 9, i. H.
  • the hand lever and the fastening element 2 are coupled to one another via these two parts.
  • To disengage pull the hand lever 1 in the direction of arrow 20 while the spindle 17 is held tight, whereby the spring 9 may be compressed to the block position. You can then turn the hand lever 1 perpendicular to the image plane relative to the fastening element 2 by a predetermined angle. As soon as the teeth and tooth gaps of the two coupling parts are again in a suitable assignment, the coupling is engaged again when the hand lever 1 is released due to the tension of the spring 9.
  • the fastening element 2 consists of a solid or hard material, preferably metal
  • the hand lever-side coupling element 11 is also made of metal, for example as a die-cast part
  • this tooth coupling can transmit large forces.
  • Secure anchoring of the hand lever-side coupling element 11 in the material of the hand lever 1 can be achieved via the anchoring elements 13.
  • An additional or alternative anchoring could also be achieved via a roughened outer cylinder circumference or anchoring elements attached there.
