Definitions

  • the present invention relates to a damping device for a ball sports racket provided with a frame and stringing, with an elastically deformable base body, which has a groove for receiving a string of stringing on at least two opposite side surfaces.
  • Ball sports rackets such as tennis rackets for practicing tennis are well known.
  • Other ball sports rackets are badmington rackets, racquetball rackets, squash rackets, etc.
  • Damping devices of this type also known as vibration dampers, are used to dampen vibrations in the strings when the string is struck. In particular, this should reduce the risk of an injury to the elbow, which can lead to so-called "tennis elbow".
  • the damping devices have an elastically deformable base body on at least two opposite side surfaces, preferably on three side surfaces each has a groove for receiving a string of the stringing. For insertion into the stringing, the base body is deformed until the grooves snap into two opposite, parallel strings and, if necessary, a cross string.
  • a damping device according to claim 1, wherein a limp safety line is firmly connected to the base body and is adapted to be releasably connected to a frame of a ball sports racket.
  • the safety line can be connected to the frame of the ball sports racket in such a way that the base body (the actual damper) cannot be lost, even if it slips out of the stringing, e.g. if the ball is badly hit.
  • the racquet can also be played with a high level of consistency without any changes in the impact characteristics.
  • the safety line does not interfere.
  • the safety line has a loop.
  • the loop can be placed around a web of the frame of the ball sports body.
  • the loop can be made by placing one end of such a safety line around a web of the frame and then knotting it.
  • the safety line is designed as such as a loop.
  • both ends of the safety line are connected to the base body.
  • the base body is usually made of a thermoplastic material which has elastic properties.
  • the end or ends of the safety line can be cast in during manufacture, so that a firm connection is achieved between the safety line and the base body.
  • the safety line is designed as a loop overall, the loop as such can be placed around a web of the frame and the base body can then be passed through a protruding section of the loop in order in this way to create a knot-free yet detachable connection between the To realize base body and the frame of the ball sports racket.
  • the length of the loop is preferably 8 cm to 20 cm, in particular 10 cm to 18 cm and particularly preferably 12 cm to 16 cm.
  • the safety line is designed as a loop, ensures that on the one hand the attachment of the safety line to the frame of the ball sports racket is easy. On the other hand, it ensures that the safety line does not "wobble around" when it is hit. It is of particular advantage if the safety line is designed to be elastically deformable in the direction along its extension.
  • the safety line can preferably be stretched slightly when the damping device is connected to the frame. In particular with the dimensions mentioned above, this can be guaranteed for different types of racquets.
  • the safety line is preferably made of a plastic material. It is particularly preferred if the safety line is made of a transparent or an opaque material. In this case, the safety line is largely "invisible” and not annoying. On the other hand, however, the safety line can also be made of a signal-colored material, just to point out the safety aspect.
  • the base body has a first main surface and an opposite second main surface, which are connected by side surfaces, with at least one end of the safety line being connected to the base body in such a way that the safety line is made of the first or the second main surface exit.
  • the end of the safety line inside the base body is firmly connected to this, for example.
  • an injection molding process By an injection molding process.
  • At least one end of the safety line is connected to the base body in such a way that the safety line emerges from a side surface.
  • the latter has the advantage that any logo applied to the main surface is not disturbed.
  • the safety line emerges from a side surface of the base body that has no groove for receiving a string.
  • a ball sports racket with a frame and stringing, with a damping device of the type according to the invention being arranged between two strings of the stringing, such that the two strings engage in the grooves on opposite sides of the base body, wherein the base body is detachably connected to the frame by means of the safety line.
  • FIG. 1 shows a schematic representation of a ball sports racket with a damping device according to the invention
  • FIG. 2 shows the damping device of FIG. 1 in a state in which it is detached from the frame of the ball sports racket;
  • FIG. 3 shows a further schematic view of a damping device in a further embodiment
  • FIG. 4 shows a schematic sectional view through the damping device of FIG. 3;
  • FIG. 5 shows a schematic representation of a further embodiment of a damping device according to the invention.
  • a ball sports racket such as a tennis racket, a squash racket, a badmington racket or a racquetball racket is shown schematically and denoted by 10.
  • the ball sports racket 10 has a frame 12 to which stringing 14 is attached.
  • the stringing 14 consists of at least one string 16, the string(s) being tensioned in a longitudinal direction and a transverse direction.
  • the frame 12 has a shaft portion 18 at one end (not shown) of which a handle is provided. Furthermore, the frame 12 has an annular head section 20 on which the stringing 14 is provided.
  • the shank section 18 merges into the head section 20 via a heart 22 with a heart opening 24 .
  • a damping device 30 is also shown.
  • the damping device 30 has a base body 32 made of an elastically deformable material.
  • the base body 32 has a first major surface 34, a second major surface 36 and four side surfaces 38a-38d. Grooves are formed on at least two opposite side surfaces 38a, 38c, which run parallel to the main surfaces 34, 36 and which are dimensioned such that a string 16 can be received therein.
  • the base body 32 has at least one further groove on a further side face 38b, as indicated schematically in FIG. 1 by dashed lines.
  • the damping device 30 can be accommodated between two longitudinally tensioned strings 16, and the third groove can grip a transversely tensioned string.
  • Damping devices 30 of this generally described type are also generally known and are used to reduce or avoid vibrations in the stringing 14 during impacts or after impacts using the ball sports racket 10 .
  • the damping device 30 also has a flexible safety line 42 which has a first end 44 and a second end 46 .
  • the ends 44, 46 are firmly connected to the base body 32 (e.g. injected).
  • the safety line 42 forms a loop or is designed as a loop, as can be seen particularly easily in FIG. 2 .
  • the safety line 42 is designed to be elastically deformable in its longitudinal direction and is made of a plastic material.
  • the safety line is preferably designed as a bungee cord or the like.
  • the safety lines can also consist of a number of fine latex fibers which are elastic in the longitudinal direction.
  • the safety line can also be designed as a rubber thread or rubber cord.
  • the safety line forms a loop. Accordingly, the safety line can be inserted into the heart opening 24 and the base body 32 can be passed through the protruding part of the loop on the other side of the frame, so that a releasable connection with the frame of the ball sports racquet is created, as shown in Fig. 1 is shown.
  • the damping device 30 can then be inserted into the stringing 14, as described above.
  • FIG. 3 and 4 show a damping device 30' with a base body 32' to which a safety line 42', which emerges from a main surface 34, is attached.
  • the other end (second end 46) is connected to a clip 50 which is generally U-shaped and elastically expandable.
  • the internal cross-section of clip 50 is included selected in such a way that typical frame cross-sections can be accommodated therein, particularly in the area of the heart 22 of the frame 12.
  • the clamp 50 can be clipped onto the frame 12 from the inside and grips it elastically, so that a detachable connection with the ball sports racket is also thereby possible 10 is created.
  • FIG 5 shows a further embodiment in which, as in the embodiment of FIGS. 3 and 4, a first end 44 of a safety line 42" is connected to the base body 32".
  • the second end 46" is designed as a free end.
  • the free second end 46" is placed around the frame and then knotted, as indicated by a knot 52 in FIG enables a releasable attachment of the damping device 30" to the frame.
