Definitions

  • the invention relates to a method for producing a handle for devices that require firm access and precise guidance, consisting of a flexible sheath arranged around a core of the handle, which holds a filler that adapts to each gripping hand around the core.
  • Such handles can be found in particular on sports equipment, such as tennis rackets, golf clubs, weights, or even handlebars of bicycles.
  • the invention can be used advantageously on all other devices that require firm access and precise guidance, such as tools or other items of daily use.
  • DE 26 34 656 B1 discloses a method for producing a handle, in particular for tools and sports equipment.
  • the handle is adapted to the anatomy of the hand of the user before the first use.
  • a plastic mixture made of at least 2 components is filled into the closed space between the stem and the casing. After curing the plastic ischung Shell removed from the hardened plastic body. This method should be able to be carried out by the user himself.
  • the shape of the handle can only be changed until the plastic mass has hardened.
  • DE 38 05 997 A1 proposes to use a one-component tooth filling compound which is preactivated and suitable for light curing. Since this material can cure even in daylight, the device can be stored until the first use, despite being filled with the one-component mass, by means of an opaque packaging.
  • a device handle is known, the cavity between the core and the shell is filled with granular material that moves under the pressure of the gripping hand.
  • Anatomical adaptation to the gripping hand takes place within certain limits, but not in the manner of an impression, as is the case with the other device handles.
  • the grains change their position again after use. There is therefore only a temporary adjustment to a gripping hand, which can also change continuously during use, depending on the force applied. Precise and safe guidance is therefore not guaranteed in every case.
  • FR 24 03 172 relates to a handle of the elastic type, which deforms under the pressure of the gripping hand and adapts to the gripping hand within certain limits, but is not dimensionally stable and according to need to return to its original shape or at least change its shape. Further examples of handles of the elastic type can be found in German Patent 39 33 831 and German Offenlegungsschrift 33 241 45.
  • Handles with the same consistency of fillers can be continuously adapted to different gripping hands, but in contrast to the non-deformable hardening handles they are not very dimensionally stable and can therefore change during use due to external influences such as heat and pressure. Depending on the choice of filler, such a handle is either elastic and therefore returns to its starting position after use or changes its original shape slightly due to external influences.
  • the invention has for its object to provide a method for producing a handle for devices that avoids both the disadvantages of a filler with a consistent consistency and that of a hardening filler, so that when using the method a repeated individual, yet permanent and dimensionally stable adjustment of the handle to each gripping hand is possible.
  • the method according to the invention for producing a handle which avoids both the disadvantages of a filler with constant consistency and that of a hardening filler, results from the features of claim 1.
  • a hardening one- or two-component mass nor uses a flexible one-component mass, but rather a relatively fine-grained filling material that would not adapt permanently without further treatment of the gripping hand. Only when the pressure inside the casing is reduced compared to the external pressure does the fine-grained filling material solidify and adapt permanently to every gripping hand. Partitions dividing the shell into chambers prevent the filler from being distributed evenly in the handle under the pressure of the gripping hand.
  • the handle adapts optimally to the gripping hand when the second step of the evacuation is only initiated when the handle is ergonomically adapted to the gripping hand in the first step.
  • the handle is adapted to a different gripping hand or, for example, to a changed handle position.
  • This method optimally combines the dimensional stability of curing one-component compositions with the possibility of changing non-curing compositions of constant consistency.
  • the fine-grained filling material only acquires the property of a filler that permanently adapts to each gripping hand through the evacuation treatment.
  • Filling materials with high coefficients of friction between the individual grains are particularly suitable for carrying out the method.
  • the size and shape of the filling material should be matched to the properties of the casing in order to prevent the filling material from being pressed through.

  • Fig. 1 shows the handle generally designated 1 for a golf club. At its lower end, the handle opens into the shaft 2 of the golf club handle, which is only partially shown in FIG. 1 and which extends as the core 3 into a casing 4 of the handle 1.
  • the sleeve 4 consisting of rubber in the exemplary embodiment is essentially closed by an inner sleeve 5, which forms a cavity for receiving the core 3.
  • the flexible sleeve 4 holds a filler 6 around the core 3.
  • the filler is already adapted to the gripping hand.
  • the recessed grips 7 which can be seen in FIGS. 1 and 2 as an imprint of the gripping hand illustrate the difference from a conventional golf club grip, as is shown, for example, in FIGS. 3 and 4.
  • the upward-opening conical shape of the handle 8 and its roughened surface produce the necessary force closure to counteract the centrifugal forces during the club rotation.
  • a support bead 9 located in FIG. 5 on a handle manufactured according to the invention extends the lever arm a ⁇ to the dimension .2, SO so that the gripping hand exerts a greater moment either with the same force or a same moment with less force over the handle transfers the racket. This effect significantly improves club management.
  • FIG. 7 shows a handle for a golf club with a connected vacuum hand pump.
  • the sleeve 19 made of rubber encases a granular, granular filling which is initially unshaped around the core 21 of the handle 22 in the sleeve 19.
  • a connection adapter 23 with an integrated valve 24 the air enclosed by the casing 19 escapes under the pressure of the gripping hand.
  • the granular filling material 25 adapts to the gripping hand.
  • a vacuum hand pump 26 placed on the connection adapter 23 serves for the further evacuation of the space 27 enclosed by the casing 19. The further decreasing pressure solidifies the filling material in the form of the handprint.
  • valve 24 By opening the valve 24, the user can again allow air to flow into the cavity 27 at any time and adapt the shape of the handle 22 again.
  • the filling material can be filled in via an opening (not shown in the figures).

Abstract

L'invention concerne un procédé de fabrication d'une poignée pour outils nécessitant une prise ferme et un guidage précis, comprenant une enveloppe flexible (4, 19) disposée autour d'une âme (3, 21) du manche (1, 22), ladite enveloppe maintenant, autour de l'âme (3, 21), une charge (6, 25) susceptible de s'adapter à la manière d'exercer une prise manuelle. On évite ainsi les inconvénients d'une charge à consistance uniforme, ainsi que d'une charge durcissante, de sorte que le présent procédé permet d'avoir une adaptation individuelle, de façon répétée, à différentes manières d'exercer une prise manuelle, suivant les utilisateurs, et cela de façon durable et stable.
