Definitions

  • the present invention relates to a handle with an adjusting device for adjusting the racket length of a ball racket according to the preamble of claim 1.
  • Such a handle is known from US-A-3,674,267.
  • the shaft merging into the racket frame is surrounded by a grip sleeve and can be displaced thereon.
  • On the inside of the grip sleeve there are longitudinal ribs that protrude inwards, the end edges of which lie against the shaft.
  • the longitudinal ribs serve to reinforce the grip sleeve.
  • the grip sleeve can be made of hard, resilient material.
  • a tennis racket is known from DE-A-2 106 800, the handle of which has a grip shell which is preferably formed from two half-shells and which is immovably attached to the shaft with the interposition of an insert made of shock-absorbing or vibration-damping material.
  • the two half shells are screwed together, the screws being inserted through bores in the shaft, the diameter of which is larger than the screw diameter.
  • the screws are fixed in position so that they do not touch the wall of the holes. Since the grip shell must not slip on the shaft, the insert must be pressed firmly against the shaft by the screws.
  • the object of the present invention is to provide a ball racket with an adjusting device of the type mentioned at the outset such that the grip sleeve is arranged so that it can be displaced on the shaft in a very stable and torsionally rigid manner, the manufacturing tolerances of the shaft and / or the grip sleeve still being able to be compensated for and still a firm, twist-proof connection between the shaft and the grip sleeve can be achieved.
  • the connection should still be so elastic that hard impacts are still well damped.
  • the displaceable grip sleeve should be adjustable quickly, easily and securely, in particular continuously, so that the grip sleeve can be moved away from or towards the field easily, preferably also during the game.
  • the edges themselves are deflected elastically after the edges rest on the shaft, or the deflectable projections are deflected elastically and rest resiliently under tension on the handle.
  • This resilient support of the edges means that the grip sleeve formed can be moved on the shaft and the grip sleeve is nonetheless fixed in position on the shaft in a manner that prevents it from rotating.
  • the adjustability of the grip sleeve has the advantage that the ball racket itself can be adjusted according to the size, the stature and / or the skill of the player, since this increases the "weight", ie. H. the center of gravity of the racket can be changed at any time.
  • the known handles do not offer this possibility.
  • the invention also provides a very torsionally and flexurally rigid grip sleeve which can simply be pushed onto the shaft and which is practically not deflectable from the longitudinal axis of the shaft. This is achieved by the position fixing elements in connection with the spring elements, the position fixing elements practically essentially finally determining the position of the grip sleeve on the shaft, and the spring elements ensuring tolerance compensation and a permanently firm, but still damping connection of the shaft and grip sleeve.
  • FIG. 1 and 2 show a possible half-shell design and a suitable adjustment device for a ball racket according to the invention.
  • a frame 2 spanning a field of play 1 merges into a shaft 3 at the handle-side end of the ball racket, in particular tennis racket.
  • the latter is preferably rectangular or square in cross section or consists of two rods, for example the rod ends, if the frame consists of a tube or is bent from a stick.
  • a bore 5 with a thread is provided in the shaft end 4, into which an adjusting screw 6 can be screwed.
  • a sleeve 9 formed from two els half-shells 7 and 8 formed sleeve parts is applied on the shaft 3 .
  • the half-shells 7, 8 consist of a hard, practically non-compressible, resilient material, such as hard foam, in particular based on hard polyurethane, hard PVC, polyamide, polypropylene, polyethylene, etc. These materials have the property on which made of wood, metal or plastic shaft 3 to slide relatively well and wear little.
  • the two half-shells 7, 8 placed on the shaft 3 are wrapped with an elastic band 11 shown in FIG. 1a, for example a grip band.
  • an elastic band 11 shown in FIG. 1a for example a grip band.
  • the half-shells 7, 8 are pulled against one another and lie flush against the shaft 3.
  • the grip sleeve 9 thus formed can be moved relatively easily on the shaft 3 with the inner walls of the half-shell 7, 8.
  • the inner walls are provided with longitudinal ribs, which serve as sliding surfaces and at the same time are used for tolerance compensation, as will be described in detail later.
  • the adjusting screw 6 serving as an adjusting device and acting between the handle sleeve 9 and the shaft 3 is provided.
  • the latter is connected to the grip sleeve 9 by a tongue and groove guide, in that the adjusting screw 6 carries a circumferential groove 14 formed between two guide disks 12, 13 at the outer end region. In this engage at the outer ends 15 of the half-shells 7, 8 inwardly projecting teeth or springs 16, which are formed in the illustrated embodiment by inwardly projecting walls with semicircular recesses 17 for the adjusting screw 6.
  • the adjusting screw 6 is not axially displaceable, but is rotatably mounted.
  • the grip sleeve 9 is displaceable in the longitudinal direction of the shaft 3 and thus its position can be adjusted.
  • the grip sleeve 9, the elastic band 11, the hose 20 or the hose sections 21 are then - as usual - wrapped by a suitable grip band, which need not be elastic.
  • the springs 16 are offset somewhat inwards, so that the head 18 of the adjusting screw 6 is arranged recessed in a recess 22.
  • the teeth or springs 16 are provided on special sliding components 28, which consist of highly wear-resistant material with low friction.
  • the material used for this purpose is, for example, polyamide, polycarbonate, aluminum, brass, steel or the like.
  • two sliding components 26 that can be assembled into a disc can be inserted with the springs 16 into the recess 22 at the outer end 15 of the grip sleeve 9 and fastened therein.
  • the attachment is preferably done by screwing and / or
  • the outline of the recess 22 is out of round and the sliding members 26 are adapted to this outline, so that the latter are held in the recess 22 non-rotatably and can be easily attached by snapping and / or gluing.
  • the half-shells 7, 8 can be provided with a soft-elastic layer 27, for example made of foam, foam rubber or the like, or subsequently coated with it, for example by extrusion coating. This gives good damping of hard impacts and shocks so that they are not transmitted directly to the player's striking arm.
  • This embodiment is shown in FIG. 2 using the lower half-shell 8.
  • This layer 27 can, even if it represents a uniform covering, be provided with the expediently elastic grip tape 11 and / or hose 20 or the hose sections 21.
  • At least one expansion joint 29 is provided in at least one wall of the half-shell 7, 8, preferably in the wall 28 present between the separating surfaces 23.

  • At least the pins 31 are expediently tapered slightly towards the end, for example at an angle of 1 to 5 degrees, so that they wedge when pressed into the bushing 30.
  • the thickness of the pins 31 and the width of the bores of the bushes 30 and the length of the wall parts 32 of the half-shells 7, 8 adjoining the dividing line 23 are expediently dimensioned such that when the half-shells 7, 8 abut the shaft 3, a small gap between adjacent ones Parting surfaces 23 remain and bushes 30 and pins 31 already result in a fixed plug connection, which holds the grip sleeve 9 thus obtained on the shaft 3.
  • the length of the adjusting screw 6 and the depth of the bore 5 are dimensioned such that the grip sleeve 9 is displaceable on the shaft 3 by approximately 20 mm to 40 mm. As a rule, however, an adjustment of ⁇ 10 mm from the normal setting is sufficient, as tests have shown.
  • connecting elements 30, 31 can again be provided and / or an elastic sheath 27 surrounding the grip sleeve 9 can be used for this purpose, which in FIG. 6 consists of an overmolded soft plastic material, for example softly set polyurethane foam, whereby at In this arrangement according to the invention, the separating surfaces 23 do not abut or meet one another. There is therefore always a small gap between these separating surfaces 23 which, in conjunction with the pressure caused by the elastic covering 27, ensures that the grip sleeve 9 and thus also the grip on the shaft 3 are held securely.

  • the central ribs are 33 'directly against the upper or lower side wall 34 of the shaft 3 directed.
  • Such or a similar embodiment is special suitable for good displaceability of the grip sleeve 9 on the shaft 3.
  • the vertical arrangement of the ribs 33 ', 33 "towards the bottom 36 enables simple manufacture of the half-shells 7, 8 in a two-part injection mold.
  • the covering 27 is achieved here by means of a rubber hose or a plurality of rubber bands or by means of a grip band to be wound up.

This gives good damping of hard impacts and shocks so that they are not transmitted directly to the player's striking arm.
  • the gripping sleeve 9 on the inside and the shaft 3 on the outside would have to be adapted very precisely to one another.
