Definitions

  • the invention relates to a tuning mechanism for stringed instruments, in particular for guitars or electric basses, with the features specified in the preamble of claim 1.
  • Such tuning mechanisms are known to be mounted with their housing on the top plate at the end of the instrument neck, wherein they have a housing part designed for insertion into corresponding bores. In this case is an upwardly protruding from it
  • Winding axle rotatably mounted, which has an insertion opening for attachment of a string end. Furthermore, a manual rotary drive for the winding axis is provided in the housing.
  • the string end is guided through the insertion opening and the tuning mechanism is actuated by rotating the winding axis until a plurality of turns of the string end lie on the winding axis and the string is fixed in the tensioned state.
  • the end of the string is therefore self-locking due to the string tension on the winding axis.
  • the above-mentioned rotary drive for the winding axle has a manually operable rotary handle and a transmission gear arranged between the rotary handle and the winding axle-as a rule a worm gear.
  • the transmission is designed to be self-locking, so that a certain position of the winding axis is maintained even under the influence of the string tension to keep the mood of the string.
  • the transmission gearbox can be displaced, in particular in the case of external shocks, resonances or other heavy loads, such as those associated with modern playing techniques, such as bending, tabing or tremolo, as a result can be out of tune with the string mechanics.
  • the object of the invention is to improve a tuning mechanism so that a set pitch of the string can be more reliably and permanently maintained.
  • the locking device on a clamping chuck in which a drive shaft of the transmission gear rotatably and locked by clamping the clamping chuck sits.
  • the clamping chuck is locked by a clamping nut which is designed as a union nut, wherein the clamping nut and clamping arms of the clamping chuck act on each other in particular via wedge surfaces.
  • Such clamping constructions are known as such, for example, in the case of telescopic rods which can be adjusted steplessly, as in the case of microcontrollers, ski and hiking poles or the like, and have a good clamping effect with a simple and compact design.
  • the clamping nut and the actual rotary handle for the tuning mechanism are formed by coaxially sitting, essentially cylindrical knobs of the same outside diameter.
  • the operating part of the tuning mechanism with adjustment and locking function is ergonomically operable and has a "tidy" Appearance.
  • FIG. 1 is a schematic sectional view of a tuning mechanism in a first embodiment
  • FIG. 2 is a schematic sectional view of the tuning mechanism from Pfeilrich ⁇ tion II of FIG. 1st
  • Fig. 3 is a schematic sectional view in Fig. 2 analogous direction of a tuning mechanism in a second embodiment.
  • the designated as a whole with 1 tuning mechanism sits in a hole 2 in a head plate 3 of a guitar not shown, an electric bass or the like.
  • the housing 4 of the tuning mechanism 1 is constructed in several parts with a gear box 5, an axle socket 6 attached thereto and a retaining flange 7 which can be screwed onto it.
  • a Wiclcelachse 8 is rotatably mounted for a dash-dot line indicated in the drawing 9, which is defined in a fürsteck ⁇ opening 15 of the winding shaft 8 with its end.
  • the wrapping Axle 8 extends from the gearbox 5 to beyond the retaining flange 7 addition.
  • a manual rotary drive 10 with an actuation shaft 11 and a worm gear 12 is installed in the gearbox 5.
  • a rotary knob 16 with which the actuating shaft 11 can be set into rotary motion with the worm wheel 13 of the worm gear 12, is seated on the actuation shaft 11.
  • the worm wheel 13 engages with the gearwheel 14 fastened to the winding axle 8, whereby the rotational movement of the actuating shaft 11 is transmitted to the winding axle 8.
  • a locking device designated as a whole by 17 for the rotary drive 10 is provided between the gear box 5 accommodating the worm gear 12 and the rotary knob 16.
  • this locking device 17 has a clamping chuck 18 seated around the actuating shaft 11, which is attached to the gearbox. 5 is set. Adjacent to this gear box 5, the clamping chuck 18 is provided with an external thread 19. This is followed by the clamping arms 21 applied by longitudinal slots 20 incorporated. These are each provided at their free ends with wedge surfaces 22 whose Einhüll ⁇ end is a frusto-conical lateral surface.
  • the clamping chuck 18 is acted on by a clamping nut 23 screwed onto the external thread 19, which in turn has inwardly pointing wedge surfaces 24.
  • the latter cooperate with the wedge surfaces 22 on the clamping chuck 18.
  • the actuating shaft 11 releases.
  • the tuning mechanism 1 can be adjusted via the knob 16 until the string has received their correct mood. Subsequently, the Sparxnmutter 23 is tightened again, the actuating shaft 11 is thereby lubarretiert about the clamping chuck 18.
  • the tuning mechanism 1 'shown in FIG. 3 is intended for a guitar. It differs from the tuning mechanism 1 according to FIGS. 1 and 2 essentially only in the design of the rotary knob, which here is a substantially cylindrical rotary knob 25. This in turn is rotatably coupled via a Fixierschrautoe 26 with the actuating shaft 11.
  • the external diameters d of the clamping nut 23 and rotary knob 25 are identical so that, together with the coaxial alignment of these two components, a uniform, compact appearance of the two functionalities "voices" and "locking" results.
