Definitions

  • the invention relates to a tensioning device for the skins of percussion instruments, consisting of threads provided in bearing blocks seated on the circumference of the instrument casing and of screws which are adjustable therein and act on the tire holding tire, the screws in each clamping position relative to the bearing blocks or the threads therein can be set automatically.
  • a tensioning device of this type is already known from DE-PS 28 13 883. It is used in particular in the case of percussion instruments that only require loosely tensioned skins, as is regularly the case when playing modern music, in particular beat music .
  • the screws are therefore provided on their shank with at least one circumferential flattening or indentation, which can be brought into engagement with a circumferential section of a spring clip under radial prestress within the threaded bushings and thereby rotate with the circumferential flattening or indentation - Forms locking device between screw and threaded bush.
  • SPARE BLADE only a self-locking effect in any rotational position between the screw and the threaded bushing, but it also produces a positive locking action in very specific relative positions between the screws and the threaded bushings, which can be easily felt when the screws are actuated, and thus the respective extent of the adjustment made makes it immediately noticeable or noticeable.
  • Clamping devices are also known in which a nut and a lock nut are provided on the screw shaft.
  • the respective clamping position of the screw can first be fixed against the bearing block by tightening the nut and then the nut can be blocked again against undesired loosening by additionally tightening the lock nut.
  • tensioning devices of the generic type first explained are at least user-friendly or easy to use because the tensioning screw of each tensioning device alone has to be manipulated
  • the tensioning devices of the known type described last are also cumbersome to handle because the Operation of each clamping device always requires the handling of three different actuators in a very specific order.
  • a change in the skin tension on percussion instruments with tensioning devices designed in this way is therefore very cumbersome and time-consuming.
  • the invention aims not only to eliminate the deficiencies inherent in the known tensioning devices.
  • This goal is basically achieved according to the invention by a clamping piece made of elastomeric material, in which a breakthrough is provided which is penetrated directly by the thread of the screw, the smallest opening width of the breakthrough falling below the thread outer diameter of the screw, and wherein Clamping piece on the bearing block and / or directly on the shell body or the like of the percussion instrument carrying it has a rotationally fixed bearing.
  • clamping pieces All materials of rubber-like elasticity that are available for technical use can be used to produce clamping pieces according to the invention.
  • the clamping pieces can be produced from natural rubber, synthetic rubber, rubber-like materials or other plastics.
  • the clamping pieces can be arranged in the length range of the screws which is exposed between the bearing blocks seated on the drum shell and the radial flange of the skin hoop. There you can get your non-rotatable abutment directly on the outer circumference of the drum shell.
  • the opening in each clamping piece has a circular outline shape and its diameter does not fall below the core diameter of the screw.
  • the braking force on the screw is caused solely by the fact that the threads of the screw under elastic intervene in the walls of the opening.
  • the outline shape of the opening in the clamping pieces it is also possible for the outline shape of the opening in the clamping pieces to deviate from the circular shape, and in this case its smallest opening cross-section not or only insignificantly less than the core diameter of the screw.
  • the threads of the screw shank penetrate into the walls of the opening only with limited peripheral areas with elastic deformation, while the other peripheral areas maintain a distance from the boundary walls of the opening.
  • the end section of the clamping piece that is distant from the opening is provided with a support base, the support width of which is at least equal to, but preferably greater than, the distance of the opening from this support base.
  • the purpose of this design measure is to maintain a permanently effective support connection between each clamping piece and the peripheral part of the drum shell that is adjacent to it.
  • a simple adaptability of the clamping pieces to different radii of curvature of the drum casing can be achieved according to the invention in that the support base is formed by two feet delimited from one another by an indentation.
  • REPLACEMENT LEAF is provided because this promotes the flawless appearance of each clamping device.
  • the invention also provides that the clamping pieces have a thickness which is at least a multiple z. B. four times the thread pitch of the screw corresponds to the shape that a relatively large braking surface is available for the engagement of the screw thread.
  • FIG. 1 shows a top view of a device equipped with tensioning devices for the drum or skins
  • FIG. 2 shows a section along the line II-II in FIG. 1 approximately in natural size through a tensioning device of the drum
  • FIG. 3 shows, on a further enlarged scale, a view in the direction of arrow III-III of FIG. 2 of an essential element of the tensioning device according to FIG
  • FIGS. 4 to 10 each show views corresponding to FIG. 3 of modified versions of the essential element of the tensioning device.
  • a drum 1 can be seen as an application example of the invention, which has an annular casing 2, over one end of which the skin 3 is placed. With its edges is there the skin 3 is fastened in a strip 4 which surrounds the upper end of the jacket 2 with concentric play.
  • the tire 4 has a radial flange 5 on which several, according to FIG. 1 for example eight clamping devices 6 act, which are arranged uniformly distributed over the circumference of the drum 1.
  • Each tensioning device 6 has a bearing block 7 which is rigidly seated on the outer side of the drum shell 2.
  • Either a nut thread 8 is incorporated directly into this bearing block 7, or else — in the case of a more complex construction of the tensioning device — is non-rotatably in the bearing block 7 , but against the force of a spring axially displaceable, a threaded bushing with a corresponding nut thread is used.
  • the shaft 9 of a screw 10 is engaged with the nut thread 8 and has a radial adjustment slot 12 in its head 11, for example. With the head 11, the screw 10 acts on the upper side of the radial flange 5 provided on the tire 4.
  • a rotation of the screw 10 by means of a suitable socket wrench leads to the fact that this shifts axially with its shaft 9 in the nut thread 8, with the result that the tension of the skin 3 supported on one end of the drum shell 2 changes via the tire 4 can be.
  • These securing arrangements consist of a clamping piece 13 which contains an opening 14 which is penetrated directly by the thread of the shaft 9 of the screw 10.
  • the clamping piece 13 consists of elastomeric material, for example rubber, synthetic rubber or plastic.
  • the clamping piece 13 is designed such that it receives a non-rotatable abutment either on the bearing block 7 or, as can be seen in FIGS. 2 and 3, directly on the drum casing 2 carrying the latter, when the opening 14 is removed from the shaft 9 of the screw 10 is axially penetrated.
  • the support base 15 can also easily adapt to different radii of curvature of the drum shell 2 and to different distances of the screws 10 from the drum shell 2, it is expedient that these are separated from one another by two feet 17 and 18 is formed.
  • This design allows the clamping piece 13 to be used for a wide variety of sizes and types of percussion instruments. For a perfect appearance of the clamping piece, it is still from
  • the thickness of the clamping pieces 13 should be dimensioned, at least in the area of their opening 14, in such a way that it corresponds to a multiple of the thread pitch on the shaft 9 of the screw 10, it having proven to be advantageous to adapt this thickness to at least four times the thread pitch.
  • the braking forces exerted on the thread flanks are so great that the screw 10 can only be manipulated using a suitable adjustment key, while an automatic adjustment is impossible.
  • FIGS. 4 to 10 It can be seen from FIGS. 4 to 10 that the formation of the opening 14 in the clamping piece 13 can be varied in accordance with different needs.
  • FIG. 4 it can be seen, for example, that the opening 14, which has a circular outline in accordance with FIG. 3, is surrounded at a distance by a ring made up of many small round holes 20 in order to increase the elasticity of the walls of the opening 14.
  • the opening 14 has a square outline shape, with the result that only four limited circumferential areas of the thread on the shaft 9 of the screw 10 penetrate the breakthrough walls with elastic deformation, while circumferential areas lying in between remain free from this engagement.
  • the opening 14 has a hexagonal outline, while according to FIG. 7 it is present with an octagonal outline.
  • each opening 14 again has an essentially circular outline, whereby however, at several evenly distributed circumferential locations there are radially inwardly directed knobs or beads 21. While the largest diameter of the openings 14 according to FIGS. 8 and 9 should at least correspond to the outer diameter of the shaft 9 of the screw 10, the knobs or beads 21 can be designed in such a way that they narrow the passage cross section to a dimension which corresponds to that Core diameter on the shaft 9 corresponds to the screw 10 or even falls short of it.
  • FIG. 10 shows a design of an opening 14 in a clamping piece 13 which is further developed from FIGS. 8 and 9.
  • the opening 14 has an approximately star-shaped shape, which is delimited on the one hand by six inwardly projecting beads or knobs and on the other hand by six intervening recesses.
  • the opening 14 is expediently designed such that its largest diameter dimension exceeds the outside diameter of the thread on the shaft 9 of the screw 10, while the smallest or free diameter has a smaller dimension than the core diameter of the thread on Shank 9 of screw 10.
