Definitions
- the present invention relates to a device which dampens the vibrations of the strings to which tennis rackets are subjected following a ball impact, and causing articular disorders at the elbow of the player.
- the patent N ° 2.585.257 is of a design modeled on the patent N ° 1.398.833 of 3/31/64, it must be of a mass too important to be really effective because it is supported only on a single mesh of the sieve, furthermore its flyweight is relaxed by the compression of the peripheral meshes, which makes it incapable of damping a mode of vibration.
- the present device makes it possible to remedy these drawbacks by acting coherently on all the modes of vibration of the sieve of the racket.
- the device in its preferred form, consisting of a flexible elastomeric elongating element interweaving in the meshes of the rope by following any path without modifying either the geometry or the tension. Its qualities of flexibility and elasticity also allow it another implementation which is carried out by entwining a turn on Your strings of the sieve, te - dispositff -is provided at its ends with spherical bulges gripping the cord. These prominences can also be used to " tie the device on the intersection of two strands, or to insert them into housings arranged around the perimeter of the frame of the racket. At least one bulge in the middle of the device is intended to stiffen it and to increase its local linear mass in order to give it optimum damping properties during vibrations of the rope.
- the device is made of an elastomeric material based on silicon or natural rubber offering good resistance to tearing and endowed with viscous-elastic property. providing it with good structural damping,
- the device may be hollow.
- FIG. 3 shows the section along A of the elongated element (1)
- FIG. 4 shows the device interwoven in the screen along a transverse axis.
- the frame (5) of the racket has recesses (4) for accommodating the spherical shapes (2).
- Figure 7 shows the device placed in the sieve of the racket embracing the strands, making a turn, in a transverse direction, to the axis of the racket handle.
- Figure 8 shows the other side of the racket of the device enla ⁇ erating the strands of the rope.
- the device according to the invention is simply made of flexible elastomer by molding; the process used can be compression or injection molding.
- the device according to the invention is particularly designed to cancel vibrations on the tannis rackets. It can be interlaced in the sieve taking transverse, longitudinal, diagonal directions, or following a curved path.
