Claims22
A ball game racket frame comprising a head portion (1), a handle portion (2) and a throat (3) connecting the head portion (1) to the handle portion (2) and comprising two throat beams (4), wherein each of the throat beams (4) merges into the handle portion (2) at a respective first transition cross-section (5) and merges into the head portion (1) at a respective second transition cross-section (6), wherein, at a distance of 10 mm from the respective first transition cross-section (5), each of the throat beams (4) has a first cross-sectional profile (7) having a first frame width (A) and a first frame height, wherein, at a distance of 10 mm from the respective second transition cross-section (6), each of the throat beams (4) has a second cross-sectional profile (8) having a second frame width (B) and a second frame height, wherein the ratio of the second frame width (B) to the first frame width (A) is at least 1.15 and the longitudinal extension (C) of the throat (3) is at least 105 mm.
A ball game racket frame comprising a head portion (1), a handle portion (2) and a throat (3) connecting the head portion (1) to the handle portion (2) and comprising two throat beams (4), wherein each of the throat beams (4) merges into the handle portion (2) at a respective first transition cross-section (5) and merges into the head portion (1) at a respective second transition cross-section (6), wherein, at a distance of 10 mm from the respective first transition cross-section (5), each of the throat beams (4) has a first cross-sectional profile (7) having a first frame width (A) and a first frame height, wherein, at a distance of 10 mm from the respective second transition cross-section (6), each of the throat beams (4) has a second cross-sectional profile (8) having a second frame width (B) and a second frame height, wherein the ratio of the second frame width (B) to the first frame width (A) is at least 1.10 and the first frame width is at most 12.5 mm.
