Definitions

  • the invention relates to a handle for a racket for ball games, in particular for tennis, squash and badminton rackets.
  • the object of the invention is to provide a handle of the type mentioned in a simple and economically feasible manner and without impairing the stability and weight and the optimal weight distribution such that a particularly effective damping of vibrations and vibrations is achieved and also an occurrence counteracting ventilation is achieved by sweating effects between the handle and the player's hand, so that the grip security and grip quality is significantly improved for the player.
  • This object is essentially achieved in that the volume of the ventilation chamber by the pressure forces exerted by the hand of the respective player during the game is changeable and that at least some of the openings provided in the grip sleeve form a suction or discharge opening for an air flow also caused by the volume changes.
  • the grip surface is preferably supported on the grip body via a plurality of spacer elements, and the variability of the volume of the ventilation chamber can be predetermined by the elasticity of the grip sleeve and / or the spacer elements.
  • the spacer elements By suitably positioning the spacer elements, the radial elasticity can also be specified in a targeted manner over the handle length.
  • the gripping sleeve has extensions or extensions extending to the club head on the front and back sides, in which are formed air inlet or outlet openings which are connected to the ventilation chamber and which in turn have opening cross-sections which are several times larger than those in the actual grip area assigned grip sleeve existing openings.
  • the comparatively large-area air inlet and air outlet openings ensure that both forehand and backhand strokes, the high movement speeds of the racket can also be used to promote air movement or air exchange in the ventilation chamber, since during these stroke movements the pressure at the inflow openings increases significantly compared to the pressure at the rear openings and the pressure difference promotes the desired flow.
  • a handle for sports rackets according to the invention which is characterized by vibration-damping properties and counteracts the formation of sweat in the grip area, consists of a grip body 1, an inner sleeve 2 and an outer sleeve 3 coaxial therewith, 3 holes or slits 4 being provided in the outer sleeve.
  • Spacer elements 6a, 6b are provided between the outer sleeve 3 and the inner sleeve 2. These spacer elements 6a, 6b support the outer sleeve 3 with respect to the inner sleeve 2 or - when working without an inner sleeve 2 - directly against the handle body 1.
  • the cross-sectional shape of the grip sleeve 3 is particularly adapted to the cross-sectional shape of the grip body 1, but this is not a necessity. Rather, it is also possible to choose the outer contour of the grip sleeve 3 independently of the cross-sectional shape of the grip body 1 in order to ensure the best possible grip properties.
  • the openings 4 provided in the grip sleeve 3 can be circular and also the shape of slots or oval Have openings, and the air exchange taking place via these openings 4 counteracts the formation of sweat in the grip area and thereby also improves the quality and safety of the grip of the respective player.
  • the grip sleeve 3 preferably consists of two identical half-shells which are spaced apart from one another via the spacer elements 6a, 6b such that they can be moved towards one another by the respective grip of the player when radial forces are exerted, but at the same time are guided on the handle body.
  • the grip sleeve 3 is provided with an extension on both the forehand side and on the backhand side, in which the air inlet openings 5 are formed.
  • These air inlet openings 5 are preferably designed in the form of lamellae, it being possible for the lamellae to be designed in a directional manner.
  • the spacer elements 6b shown in Fig. 3 preferably have the shape of webs extending in the longitudinal direction of the handle, so that between such webs air guiding areas are created between the inlet openings 5 and the ventilation chamber 8, which ensure that the ventilation chamber 8 is always along its entire length is effective and there is no undesirable shortening of the air flow paths between air inlet 5 and air outlets via openings 4.
  • FIG. 4 shows an example of the configuration of the spacer elements 6a, which can be predefined in terms of their distribution and elasticity as a function of the desired compression behavior of the grip sleeve 3.
  • these are distance elements integrally formed on the inner sleeve 2, so that there is an arrangement that can be attached as a unit on a handle body 1.
  • the inner sleeve 2 is not absolutely necessary, since the spacer elements 6a can also be supported directly on the handle body 1 and thus the ventilation chamber 8 is formed directly between the handle body 1 and the handle sleeve 3.
  • the spacer elements 6a can also be attached to the inside of the grip sleeve 3 or be formed in one piece with it, and it is also possible to use separate support elements which are fixed, for example, by gluing between the grip body 1 and the grip sleeve 3.
  • the extension parts of the grip sleeve 3, which extend towards the club surface and which are provided on the front and back and contain the air inlet openings 5, can be formed in one piece with the grip sleeve 3, but also consist of separate parts which may be made of a different material than the grip sleeve, which are then preferably fixed by clamping over the grip sleeve 3.
  • FIG. 5 shows an embodiment variant in which the air inlet openings are designed in the form of lamellae 7 and in the handle region adjoining the air inlet openings have support elements 6b in the form of a web and thus, together with the grip sleeve 3, an air duct for connecting the air inlet openings 5 to the ventilation chamber 8 establish.
  • Web-shaped support elements can also be molded directly onto the inner surface of the grip sleeve 3, and it is possible by suitable positioning of such web elements Lich to achieve a targeted air distribution within the ventilation chamber 8.
  • the support elements are arranged and, taking into account the inherent elasticity of the gripping sleeve 3 in terms of their elasticity, are selected such that during the game, due to the pressure forces exerted by the hand of the respective player and, in particular, increased prior to the ball impact moment, a pronounced pumping effect by changing the volume of the ventilation chamber 8 results.
  • the air flow which is indicated by arrows in FIG. 5, is above all also promoted by the racket movement, since in the inflow openings 5 provided both on the front side and on the back side, a pressure difference dependent on the racket speed and promoting the flow builds up.
  • FIGS. 6 and 7 show a variant in which the air inlet openings 5 formed by inclined lamellae 7 are displaced through the grip sleeve attachment part 9 into the vicinity of the grip body end 10 on the club head side, the air delivery component being increased due to the inflow speed due to the plurality of air inlet openings can.
  • the handle body 1 In order to be able to optimize the volume of the ventilation chamber 8 with regard to the desired volume changes, it is possible to provide the handle body 1 with corresponding recesses on its flat sides, since the desired outer contour of the handle is defined in a defined manner by the handle sleeve 3 supported on the handle body 1 and thus corresponding modifications of the handle body 1 have no effect on the outer contour of the handle.
  • the grip sleeve 3 preferably consists of a plastic material, the radial elasticity of which can be influenced by the targeted attachment and design of the openings 4.
  • the total radial elasticity of the handle is preferred, however, by the interaction of the grip sleeve, which has a certain basic elasticity, with the spacer elements made of elastic, e.g. spacer elements made of rubber or rubber-like material.
  • the function of the spacer elements can also be provided by suitable density open-cell foam elements.
  • the air intake openings 5 are preferably provided outside the actual grip area and preferably on the club head side, it is also possible within the scope of the invention to provide these air intake openings in the actual grip area or in the region of the front end of the handle, the positioning being chosen in such a way that there is no impairment of the important grip area for the player.
  • the handle according to the invention can also be designed as a retrofittable unit for conventional handle bodies, for which purpose a simple application of this handle is preferred radial expansion elasticity is provided on the handle body.
