Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
191 words
A sun protection, especially for use with deck chairs, camping chairs, or the like, said sun protection comprising a plurality of U-shaped supporting beams each of which includes a central cross beam, a pair of laterally spaced apart side beams, a pair of angular connections for removably coupling the opposed ends of said central beam to one end of each of said side beams, a mounting ear removably connected to the end of each said side beam that is opposite said respective cross beam, a pair of clamping holders coupled to the end of said side beams opposite said respective cross beam for detachably securing said sun protection to a chair, a pair of clamping bolts adjustably coupling said mounting ears to each other and to a respective one of said clamping holders, said U-shaped supporting beams being angularly displacable with respect to each other and being angularly displacable as a unit with respect to said clamping holders, said clamping holders being formed as angular elements in one of which is removably disposed one of said clamping bolts in a torsion-resistant manner, and a foldable fabric covering said U-shaped supporting beams.
Claim 2
Dependent Claim
191 words
A sun protection, especially for use with deck chairs, camping chairs, or the like, said sun protection comprising a plurality of U-shaped supporting beams each of which includes a central cross beam, a pair of laterally spaced apart side beams, a pair of angular connections for removably coupling the opposed ends of said central beam to one end of each of said side beams, a mounting ear removably connected to the end of each said side beam that is opposite said respective cross beam, a pair of clamping holders coupled to the end of said side beams opposite said respective cross beam for detachably securing said sun protection to a chair, a pair of clamping bolts adjustably coupling said mounting ears to each other and to a respective one of said clamping holders, said U-shaped supporting beams being angularly displacable with respect to each other and being angularly displacable as a unit with respect to said clamping holders, said clamping holders being formed as angular elements in one of which is removably disposed one of said clamping bolts in a torsion-resistant manner, and a foldable fabric covering said U-shaped supporting beams.
Claim 3
Dependent Claim
44 words
The sun protection according to claim 1 whereby said cross beam and said side beams are formed of straight tubes and said angular connections and said mounting ears are formed of elements that are adapted to be detachably inserted under tension into said tubes.
Claim 4
Dependent Claim
21 words
The sun protection according to claim 1 wherein the ends of said side beams that receive said mounting ears are slotted.
Claim 5
Dependent Claim
24 words
The sun protection according to claim 3 wherein said cross beam and said side beams are provided with a plastic coating covering said slots.
Claim 6
Dependent Claim
29 words
The sun protection according to claim 3 wherein said mounting ears are slotted and are open at one side whereby said mounting ears are slidable onto said clamping bolts.
Claim 7
Dependent Claim
43 words
The sun protection according to claim 1 wherein said clamping holders are formed of a viscus elastic plastic material and include a clamping groove that is adapted to engage a portion of the chair on which said sun protection is to be mounted.
Claim 8
Dependent Claim
46 words
The sun protection according to claim 6 wherein said clamping groove of said clamping holder is formed of two sections to thereby define a jaw that is adapted to be clamped to a portion of a chair on which said sun protection is to be mounted.
Claim 9
Dependent Claim
19 words
The sun protection according to claim 1 whereby said angular connections are formed of a viscus elastic plastic material.
Claim 10
Dependent Claim
