Abstract
Abstract An eye protector (e.g. for squash players) comprises a screen slitted in the eye region of the wearer and with at least one thickened region adjacent to the slit(s) to reinforce the screen and prevent a resilient object (e.g. a squash ball) intruding through the slit and contacting a wearer's eye. Thickened regions can be provided above and below the slit(s) on the outward facing surface of the screen and the upper region can be thicker than the lower. An elasticated band can hold the screen over the wearer's eye region.

Total Claims: 6
Claim 1
Independent Claim
136 words
A squash player's eye protector comprising a slitted screen of transparent plastics material and means to support the screen across the face of a squash player to overlie the eye region of a player's face, said screen being formed with a first rigid thickened region on the outwardly facing surface of the screen defining the upper extremity of the salt and a second rigid thickened region on the outwardly facing surface of the screen defining the lower extremity of the slit, said first and second thickened regions being spaced apart at widest part of said slit by a distance which is at least 20 mm but which is less than the diameter of a squash ball, and the first thickened region defining the upper extremity of the slit projects forwardly further than the second thickened region.
Claim 2
Dependent Claim
136 words
A squash player's eye protector comprising a slitted screen of transparent plastics material and means to support the screen across the face of a squash player to overlie the eye region of a player's face, said screen being formed with a first rigid thickened region on the outwardly facing surface of the screen defining the upper extremity of the salt and a second rigid thickened region on the outwardly facing surface of the screen defining the lower extremity of the slit, said first and second thickened regions being spaced apart at widest part of said slit by a distance which is at least 20 mm but which is less than the diameter of a squash ball, and the first thickened region defining the upper extremity of the slit projects forwardly further than the second thickened region.
Claim 3
Dependent Claim
172 words
A squash player's eye protector comprising a curved screen of transparent plastics material and an elasticated strap for supporting the screen on the head of a squash player so that the screen overlies the eye region of the face of the player, means defining an opening in the screen in front of each eye of the player, a first rib defining the upper extremity of each opening and projects forwardly of the screen away from the face of the player, a second rib defining the lower extremity of each opening, said second rib also projects forwardly of the screen away from the face of the player but by a lesser amount than said first rib, the spacing apart of the ribs at the widest part of each opening being at least 20 mm and each rib being such that a squash ball is prevented from contacting an eye of the player through either opening, irrespective of the angle of approach of the ball to the screen or the speed of that approach.
Claim 4
