Definitions

• the invention relates to a device for carrying out a ball game, in particular badminton, which has a handle, a shaft and a racket head.
• Devices of this type are usually designed as a racket which is gripped in the region of the handle with the hand of the user and which is hit with the club head against the ball to be played after a corresponding swinging out.
• the usual racket designs represent a compromise between enabling a sensitive playing style and enabling hard and high-energy shots. Because of this realization as a compromise between different requirements, there is a ne optimal construction with regard to the respective individual requirements.
• the object of the present invention is therefore to construct a device of the type mentioned in the introduction in such a way that improved playability is supported.
• This object is achieved in that a weight is guided in a position-changing manner along at least part of a longitudinal extent of the shaft.
• the weight be resiliently braced relative to a stop.
• a sensitive way of playing at low striking speeds is supported in that the weight is acted upon by a spring element with a spring force oriented in the direction of the handle. It is also advantageous for a sensitive playing style at low impact speeds that a pretensioning force of the spring element prescribes a response threshold for a change in position of the weight along the shaft.
• a defined working area is provided in that a positioning path for the weight of two stops is limited.
• At least one of the stops be designed as a damping element.
• a simple constructive implementation is provided in that the weight is guided on the outside along the shaft.
• a tensioning force of the spring element can be predetermined by an adjusting element.
• a plurality of defined settings are provided in that detents are provided for defining at least two positions of the setting element.
• a simple and compact implementation is also supported in that the spring element is formed from at least two rubber bands.
• the number of components used can be reduced in that the rubber bands of a deflection are interconnected and form a common component.
• Fig. 1 shows an embodiment of the device as
• the device has a handle (1), a shaft (2) and a racket head (3).
• the club head (3) consists of a frame (4) and a bracing
• the frame (4) is attached to the shaft (2) and frames the bracing (5).
• a weight (6) is slidably guided along the shaft (2).
• the stops (8, 9) are preferably made of a damping material, for example rubber or plastic.
• the weight (6) is braced by a spring element (10) against the stop (8), which is arranged facing the handle (1).
• the spring element (10) can be formed from elastic bands. According to the embodiment in FIG. 1, two elastic bands are used.
• the spring element (10) is connected to an adjusting element (11) for specifying a clamping force.
• the adjusting element (11) can be arranged in the region of the extension of the handle (1) facing away from the shaft (2).
• the elastic bands in the area of the handle (1) extend through guide elements (12) which are arranged between a handle body (13) and a handle wrap (14).
• the guide elements (12) can, for example, be tubular or designed as an open guide profile.
• the adjusting element (11) can be fixed in the region of the handle (1) with the aid of a locking device (15).
• the guide element (12) is inserted in some areas into a handle interior (16).
• Fig. 2 shows a side view of the racket according to Fig. 1. It can be seen again in particular that in a basic state, the weight (6) is pulled by the spring element (10) against the stop (8).
• Fig. 3 shows a detailed view of the structure of the setting element (11). It can be seen that the adjusting element (11) is provided with a profile (17) and a central pin (18). In addition, the adjusting element (11) has a transverse bore (19) through which a spring element (10) designed as a rubber band can be passed. This makes it possible to use only one component in order to act on the weight (6) in two places.
• Fig. 4 shows a base element (20) for the setting element (11).
• the base element (20) is inserted into the interior of the handle (16) and has a counter-profiling (21) for the profiling (17).
• the profiling (17) and the counter-profiling (21) together form sam a grid.
• the base element (20) is also equipped with a bore (22) into which the central pin (18) of the adjusting element (11) can be inserted.
• Fig. 5 shows a possible embodiment for the profiling (17) or the counter-profiling (21).
• the respective tension of the spring element (10) can be influenced by appropriate adjustment of the adjusting element (11).
• Fig. 6 shows an enlarged view of a possible design for the shaft (2).
• the shaft (2) is of tubular construction here in order to support a resilient deflection when performing an impact movement.
• Fig. 7 shows an embodiment of the weight (6) with a structure of two half-shells (23).
• the half-shells (23) delimit a central recess (24) through which the shaft (2) is guided.
• the half-shells (23) can be connected to one another using screws (25).
• recesses (26) are provided, through which the ends of the elastic band can extend when the spring element (10) is designed as a rubber band.
• FIG. 9 shows a simplified representation of the outer contour of the half-shells (23).
• 10 and 11 illustrate the structure of the stops (8, 9).
• the stops (8, 9) are each pushed onto the shaft (2) and surround it in a ring.
