Claims

[Claims for Utility Model Registration] 1. A synthetic fiber-containing frame having an opening at one end constituting an arcuate portion and a handle pallet at the other end, wherein the handle pallet can be molded into a soft, dense indexable shape. formed from a non-rigid cellular foam material, the arcuate portion being formed to have a normal cross-sectional shape located around a majority of the arcuate portion and extending in the direction of the axis of the arcuate portion, and having a soft, durable structure. A tennis racket comprising a grommet strip formed from a certain wear-resistant material and secured around a majority of the radially outer edge of the bow. 2. The molding material of the handle pallet has a uniformly increasing density, with a higher density adjacent to the outer surface of the handle pallet material and a lower density adjacent to the frame. The tennis racket according to claim 1. 3 The handle pallet is about 6 on shore A scale.
3. A tennis racket according to claim 2, which is molded from urethane having a durometer hardness of 0 to 80. 4. A tennis racket according to claim 3, wherein the handle pallet is preferably formed from urethane having a durometer hardness of about 60 to 70 on the Shore A scale. 5. A tennis racket according to claim 4, wherein the handle pallet is most preferably molded from urethane having a durometer hardness of about 65 on the shore A scale. 6 The cross section of the arcuate part over most of its length is approximately 1

．． A tennis racket according to claim 1 having an axial to radial ratio of 50 to 1.83:1. 8 The cross section of the arcuate part over most of its length is approximately 1
．． 8. The tennis racket of claim 7 having an axial to radial ratio of 67 to 1. 9. The tennis racket of claim 1, wherein the grommet strips are molded from a polyurethane-polycarbonate blend having a durometer hardness of about 52 to 62 on the Shore D scale. 10. The tennis racket of claim 9, wherein the grommet strips are molded from a polyurethane-polycarbonate blend having a durometer hardness of about 57 on the Shore D scale. 11 a recess on the radially outer edge of the arc for most of its length for receiving a damping strip and extending through said arc for receiving a hollow string-receiving tube formed as part of said damping strip; 2. A tennis racket according to claim 1, further comprising a radial hole. 12. A tennis racket according to claim 11, wherein the grommet strip is axially enlarged across the head end of the bow to define a buffer strip. 13. The tennis racket of claim 12, wherein the grommet strip is provided with a string receiving tube adapted to be received within a radial hole formed as part of the grommet strip and extending through the arc. 14 A frame having an opening at the head end constituting an arcuate portion and a handle pallet at the handle end, the handle pallet being indexable into a soft, dense indexable material having a durometer hardness of about 60 to 70 on the shore A scale. urethane, the arcuate portion being enlarged in the direction of the axis of the aperture, located around the majority of the aperture, and having a radial dimension of about 12 mm and an axial dimension of about 20 mm ± about 10%. formed to have a cross-sectional shape of
A glue molded from a soft, durable, abrasion-resistant polyurethane-polycarbonate blend having a durometer hardness of approximately 57±5 on the shore D scale and secured to the radially outer edge of the arc around the majority of the aperture. A tennis racket with mesh strips. 15. The tennis racket of claim 14, wherein the frame is made from graphite fibers and other materials.
