Definitions

  • the present invention relates to a bridge for a ball game racket and a ball game racket with the bridge according to the invention.
  • Racket frames for ball game rackets typically include a handle portion, a club head, and a heart portion disposed therebetween, the heart portion being formed by two frame spars extending from the handle portion and a bridge.
  • the bridge takes over several, essential for the playing behavior of the ball game rackets functions.
  • the bridge usually absorbs several longitudinal strings of the clothing and thus influences the behavior of the clothing. In particular, for geometric reasons, these are the central longitudinal strings that run through the so-called "sweet spot" and thus have a decisive influence on the player's perceived feel of the game.
  • the bridge closes the club head to an annular structure, which has a decisive influence on the deformability of the club head.
  • the bridge also stabilizes the two frame spars and thus affects the overall stability of the ball game racket frame.
  • the invention is directed to a bridge for a ball game racket, the bridge having a central portion and two edge portions intended to be connected to the frame of a ball game racket. At least one lower web and at least two upper webs extend from the middle section on both sides to the two edge sections.
  • the middle section has first passage openings for receiving longitudinal strings. At least two further passage openings for receiving longitudinal strings are arranged such that the longitudinal strings to be received by them extend in each case between the corresponding two upper webs.
  • the directions “down” and “up” refer to the orientation of the bridge in the assembled state, ie, when the bridge is connected to the rest of the frame of a ball game racket, the ball game racket is oriented so that the handle portion below and the club head located at the top.
  • the two lower webs are on the handle portion facing side of the bridge and the four upper webs on the head portion facing side of the bridge.
  • the middle section together with the two lower webs preferably has the function of a regular bridge, wherein in particular the central section has passage openings for receiving longitudinal strings and is preferably provided for deflecting one or more longitudinal strings in the region of the central section.
  • the two lower webs also each have passage openings for receiving longitudinal strings, wherein the longitudinal strings do not necessarily have to be deflected in the region of the lower webs. Rather, one or more longitudinal strings can each be passed through one of the lower webs and up to the corresponding frame members of the ball game racket frame.
  • the at least four upper webs are preferably not the recording or deflection of strings, but rather the stabilization of the bridge through a connection further up the club head.
  • the connection of the bridge to the racket frame by means of the four upper webs and the two lower webs on the one hand allows a good application of force acting on the bridge forces in the club head and on the other hand excellent stabilization against torsional deformation.
  • the bridge is formed substantially mirror-symmetrical, wherein in the assembled state of the bridge, the string plane formed by the covering forms the associated Speigel composition.
  • the bridge is designed such that the longitudinal strings to be received by the at least two second through openings each extend without contact between the corresponding two upper webs.
  • the webs are preferably geometrically separate elements, which are preferably spaced from each other. It is preferred that each of the lower web between the central portion and the corresponding edge portion is connected to neither of the two upper webs. Furthermore, the two upper webs between the middle section and the corresponding edge section are preferably not connected to each other. Preferably, the distance between the two upper webs at least in sections at least 5 mm, preferably at least 10 mm and more preferably at least 15 mm, wherein the distance between two opposite outer surfaces of the webs, measured perpendicular to the clothing plane is meant. In other words, the distance between the webs corresponds to the extent of the gap between the two webs.
  • the projection of the distance between in each case one of the upper webs and the lower web is at least partially at least 5 mm, preferably at least 10 mm and particularly preferably at least 15 mm, on the clothing plane formed by the clothing.
  • this distance is to be understood as a distance between the opposite outer surfaces of the respective webs and thus refers to the dimensions of the gap between adjacent webs (projected on the string plane).
  • a passage opening is formed in each case between the two upper webs and the lower web, which appears in a viewing direction perpendicular to the clothing plane as a passage opening.
  • the visible cross-sectional area of this passage opening is preferably at least 1.5 cm 2 , more preferably at least 2 cm 2 and more preferably at least 2.5 cm 2 .
  • the bridge structure makes the bridge not only lighter overall, but also acts through the through holes formed between the webs less massive and therefore provides a particularly aesthetic overall impression.
  • the passage openings are also aerodynamically advantageous.
  • the distance between each one of the two upper webs and the lower web from the center distance to the corresponding edge portion increases. It is further preferred that in each case the distance between the two upper webs increases from the middle section to the corresponding edge section in order to make the middle section of the bridge as narrow as possible, but on the other hand to connect the two upper webs in the region of the outer sides of the frame section forming the club head enable.
  • the two edge portions of the bridge can each be formed by the outer ends of the webs, wherein the outer ends of the webs of both edge portions can be connected to each other or can be separated from each other.
  • the edge portions of the bridge or these outer web ends can then be connected in any way with the rest of the frame of the ball game racket, for example by screwing, welding, gluing, etc.
