Abstract
Abstract A connecting member is movably connected to a carrying case body and connected to a carrying case cover and operable to move said cover relative to said body between a closed position and a position for use. A mirror is carried by and substantially rigid with said cover and extends substantially parallel thereto. The cover is arranged to define in said closed position with said case body an interface extending substantially in a plane. Said case body, connecting member and cover define for said cover an axis of rotation, which is spaced outwardly from said case body and parallel to said interface and about which said cover is movable between said closed position and said position for use.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
190 words
An arrangement for use in projection, which comprises a carrying case body, a carrying case cover, a connecting member connected to said cover and movably connected to said case body and operable to move said cover relative to said body between a closed position and a position for use, and a mirror which is carried by and substantially rigidly connected with said cover and extends substantially parallel thereto, said cover being arranged to define in said closed position with said case body an interface extending substantially in a plane, said case body, connecting member, and cover defining for said cover an axis of rotation which is spaced outwardly away from said case body and parallel to said interface and about which said cover is movable between said closed position and said position for use, a second mirror, which is hinged to said connecting member and arranged to be pivotally movable from an inoperative position to an operative position in response to a movement of said connecting member from a position corresponding to the closed position of said cover to a position corresponding to the position for use of said cover.
Claim 2
Dependent Claim
190 words
An arrangement for use in projection, which comprises a carrying case body, a carrying case cover, a connecting member connected to said cover and movably connected to said case body and operable to move said cover relative to said body between a closed position and a position for use, and a mirror which is carried by and substantially rigidly connected with said cover and extends substantially parallel thereto, said cover being arranged to define in said closed position with said case body an interface extending substantially in a plane, said case body, connecting member, and cover defining for said cover an axis of rotation which is spaced outwardly away from said case body and parallel to said interface and about which said cover is movable between said closed position and said position for use, a second mirror, which is hinged to said connecting member and arranged to be pivotally movable from an inoperative position to an operative position in response to a movement of said connecting member from a position corresponding to the closed position of said cover to a position corresponding to the position for use of said cover.
Claim 3
Dependent Claim
44 words
An arrangement as set forth in claim 1, which comprises spring means urging said connecting member toward its position corresponding to the position for use of said cover and spring means urging said second mirror toward said operative position relative to said connecting member.
Claim 4
Dependent Claim
182 words
An arrangement for use in projection, which comprises a carrying case body, a carrying case cover, a connecting member connected to said cover and movably connected to said case body and operable to move said cover relative to said body between a closed position and a position for use, and a mirror which is carried by and substantially rigidly connected with said cover and extends substantially parallel thereto, said cover being arranged to define in said closed position with said case body an interface extending substantially in a plane, said case body, connecting member, and cover defining for said cover an axis of rotation which is spaced outwardly away from said case body and parallel to said interface and about which said cover is movable between said closed position and said position for use, a substandard motion picture projector accommodated in said case body, and switch means connected to said connecting member and arranged to render said projector ready for operation in response to a movement of said connecting member to its position corresponding to the position for use of said cover.
Claim 5
Dependent Claim
182 words
An arrangement for use in projection, which comprises a carrying case body, a carrying case cover, a connecting member connected to said cover and movably connected to said case body and operable to move said cover relative to said body between a closed position and a position for use, and a mirror which is carried by and substantially rigidly connected with said cover and extends substantially parallel thereto, said cover being arranged to define in said closed position with said case body an interface extending substantially in a plane, said case body, connecting member, and cover defining for said cover an axis of rotation which is spaced outwardly away from said case body and parallel to said interface and about which said cover is movable between said closed position and said position for use, a substandard motion picture projector accommodated in said case body, and switch means connected to said connecting member and arranged to render said projector ready for operation in response to a movement of said connecting member to its position corresponding to the position for use of said cover.
Claim 6
Dependent Claim
40 words
An arrangement as set forth in claim 3, in which said switch means are adapted to energize said projector in response to a movement of said connecting member to its position corresponding to thE position for use of said cover.
Claim 7
Dependent Claim
191 words
An arrangement for use in projection, which comprises a carrying case body, a carrying case cover, a connecting member connected to said cover and movably connected to said case body and operable to move said cover relative to said body between a closed position and a position for use, and a mirror which is carried by and substantially rigidly connected with said cover and extends substantially parallel thereto, said cover being arranged to define in said closed position with said case body an interface extending substantially in a plane, said case body, connecting member, and cover defining for said cover an axis of rotation which is spaced outwardly away from said case body and parallel to said interface and about which said cover is movable between said closed position and said position for use, said carrying case body comprises a first axis, about which said connecting member is pivoted, said connecting member comprises a second axis, about which said carrying case cover is pivoted, and said axis of rotation results from a pivoting movement of said connecting member about said first axis and from a pivoting movement about said second axis.
Claim 8
Dependent Claim
191 words
An arrangement for use in projection, which comprises a carrying case body, a carrying case cover, a connecting member connected to said cover and movably connected to said case body and operable to move said cover relative to said body between a closed position and a position for use, and a mirror which is carried by and substantially rigidly connected with said cover and extends substantially parallel thereto, said cover being arranged to define in said closed position with said case body an interface extending substantially in a plane, said case body, connecting member, and cover defining for said cover an axis of rotation which is spaced outwardly away from said case body and parallel to said interface and about which said cover is movable between said closed position and said position for use, said carrying case body comprises a first axis, about which said connecting member is pivoted, said connecting member comprises a second axis, about which said carrying case cover is pivoted, and said axis of rotation results from a pivoting movement of said connecting member about said first axis and from a pivoting movement about said second axis.
