Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
115 words
A portable light comprising a battery case, a lamp housing and means for mounting said lamp housing to said battery case for movement between a closed position and an open position, said battery case including a generally planar upper face panel and a back panel generally paralleling said face panel in spaced relation thereto, substantially continuous peripheral wall means between and joining said panels and defining a battery compartment therebetween, said lamp housing defining a bulb compartment with an open face, said lamp housing in the closed position overlying said upper face panel with the open face of said bulb compartment substantially engaged with and closed by said upper face panel of the battery case.
Claim 2
Dependent Claim
115 words
A portable light comprising a battery case, a lamp housing and means for mounting said lamp housing to said battery case for movement between a closed position and an open position, said battery case including a generally planar upper face panel and a back panel generally paralleling said face panel in spaced relation thereto, substantially continuous peripheral wall means between and joining said panels and defining a battery compartment therebetween, said lamp housing defining a bulb compartment with an open face, said lamp housing in the closed position overlying said upper face panel with the open face of said bulb compartment substantially engaged with and closed by said upper face panel of the battery case.
Claim 3
Dependent Claim
57 words
The portable light of claim 1 including means for forming an electrical circuit between said battery case and said lamp housing, and switch means responsive to movement of said lamp housing for opening said circuit in said closed position of said lamp housing and closing said circuit upon movement of said lamp housing from said closed position.
Claim 4
Dependent Claim
65 words
The portable light of claim 2 wherein said means for mounting said lamp housing to said battery case comprises a pivot mount fixed to and extending from said upper face panel, and complementary means on said lamp housing pivoting said lamp housing to said pivot mount whereby said movement of said lamp housing between said closed position and said open position is a pivotal movement.
Claim 5
Dependent Claim
42 words
The portable light of claim 3 wherein said pivotal movement is adjacent said peripheral wall, said lamp housing, in said open position, extending from said upper face panel at an angle to said upper face panel of up to approximately 180 degrees.
Claim 6
Dependent Claim
53 words
The portable light of claim 4 wherein said pivot mount comprises a pair of laterally spaced posts, said complementary means on said lamp housing including a projecting extension received between said posts, and projecting lugs and receiving sockets on said extension and posts retaining said extension between said posts for relative pivotal movement.
Claim 7
Dependent Claim
43 words
The portable light of claim 5 including passage means through at least one of said posts communicating with the interior of said extension for the accommodation of wiring as a component of said electrical circuit between said battery case and said lamp housing.
Claim 8
Dependent Claim
67 words
The portable light of claim 6 wherein said switch means includes a flexible reed biased into engagement with a complementary contact, and a push button on said reed extending through the face panel of the battery case and positioned for engagement and depression by said lamp housing in the closed position of said lamp housing for deflecting said reed away from said contact and opening said circuit.
Claim 9
Dependent Claim
65 words
The portable light of claim 1 wherein said means for mounting said lamp housing to said battery case comprises a pivot mount fixed to and extending from said upper face panel, and complementary means on said lamp housing pivoting said lamp housing to said pivot mount whereby said movement of said lamp housing between said closed position and said open position is a pivotal movement.
Claim 10
Dependent Claim
42 words
The portable light of claim 8 wherein said pivotal movement is adjacent said peripheral wall, said lamp housing, in said open position, extending from said upper face panel at an angle to said upper face panel of up to approximately 180 degrees.
Claim 11
Dependent Claim
30 words
The portable light of claim 9 wherein said lamp housing, in the closed position thereof, is completely within the peripheral confines of the battery case in overlying parallel relation thereto.
