Definitions
- the oscillating elements located in a housing whose bottom is in a plane parallel to the plane of the screen have a natural frequency between 100 and 180 Hz while the oscillating elements arranged in a housing whose bottom is in a plane perpendicular to that of the sieve have a natural frequency between 120 and 200 Hz.
- FIG. 3 is a diagrammatic plan view of the second type of bending vibration
- FIG. 4 is a partial perspective representation of a support plate in which four oscillating elements are arranged
- Such a support plate 12, equipped with these oscillating elements 11, is placed in a groove 15 which is formed in the handle 5 of the racket 1. This groove 15 is then closed by the positioning of the grip 16, that is to say -to say of the covering which covers the handle 5 and which is directly in contact with the hand of the player. So that the oscillating elements 11 can oscillate freely, it is important that the height H of the groove is greater than the maximum height h taken by the support plate 12 and by each oscillating element 11 at its maximum amplitude of vibration.
- the weight of each oscillating element 11 was of the order of 0.2 g distributed approximately equally between the polyurethane gel 13 and the lead sheet 14, the said lead sheet 14 having a thickness of the order of 0.2 mm.
- the racket 1 has four grooves equipped with oscillating elements, two grooves 15 in the upper and lower faces parallel to the sieve and two grooves 15 'in the faces lateral 18 perpendicular to the sieve.
- the support plates 12, 12 ' are glued in the bottom of each groove 15, 15' so that the vibrations communicated to the handle 5 are reflected in all the oscillating elements 11, 11 '.
- the applicant has carried out tests with a view to analyzing the reduction in the amplitude of the vibrations due to the installation of the oscillating elements in accordance with the invention.
