The strings are anchored in an oval hoop that is tightly wedged in the head parts of the frame and which is detachable with respect to frame. In a preferred embodiment, a tennis racket comprises a member bowed to form the head of the racket and two rods extending from the head to form the handle which terminates in a suitable grip.
It is believed that this improvement shall have acceptance when put into practice as due to the characteristics that define same, the system can be applied to all kinds of rackets in general.
The improvement mentioned in the present specification, has solved and removed the above mentioned problems in an easy and ingenious manner, by placing a manually regulated counterweight on a guide, that is very simple and, nevertheless, positively effective, and that does not require the aid of tools for handling. To the foregoing must also be added that the threading of the stem and the counterweight, as well as their assembly implies a relative complication of the system, increasing the production cost. This difficulty can be overcome, although based on the supply of means such as lock nuts or similar, in order to prevent the possibility of the aforesaid displacements.įurthermore, the fact of having to handle nuts and lock nuts implies that the player must have special tools, for example, wrenches, which renders the system unpractical. 198,361 for a counterweight to be set by screwing on a bolt extending in the longitudinal direction of the racket.Īlthough this system is efficient, in practice it evidences some problems: especially, the fact that being screwed on, every serve tends to move the counterweight, screwing and unscrewing it in relation to the function of each impulse, that is to say, displacing same on the stem. It has previously been proposed, according to applicant's Argentine Pat. Said characteristic of a variable counterweight gives the racket an unexpected effect, as it provides same with a perfect balance in accordance with the size, material used, etc., and especially in relation with each player so as to obtain a higher or lower weight in the principal structure of the netting in relation to the command grip. The present invention refers to improvements in tennis rackets, of the type which have a counterweight movable along a guide on the handle to adjust the position of the racket's center of gravity. The tennis racket of claim 1 wherein said handle comprises a pair of rods extending from the racket head and said flat member is a plate fixed between said rods. The tennis racket of claim 1 wherein said means for rotating said screw means is a wing nut.ģ. A tennis racket comprising a racket head and a racket handle extending from said head toward a grip remote from said head, said handle including a flat member defining a longitudinal slot substantially aligned with the longitudinal axis of the handle and a counterweight means movable along said slot for adjusting the position of the center of gravity of the racket, said counterweight means comprising a pair of clamps having edge portions engaging opposite surfaces of said flat member on opposite sides of said slot, screw means connecting said clamps for movement toward and away from each other, and means for rotating said screw means by thumb and finger pressure, said edge portions of said clamps being tightened against said opposite surfaces of said flat member by tightening said screw means and said counterweight means being movable along said slot by loosening said screw means.Ģ. Same shall be put into practice, I hereby claim as myġ.
The nature of the present invention and the manner in which Having thus especially described and determined
