Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
242 words
A retractable head lamp assembly for use in combination with a lightweight vehicle having a cab at the front thereof, said cab having an opening on the top face thereof, comprising: a housing mounted in said cab and pivotable about a first axis to be moved in and out of said opening; said housing including a pair of opposite side walls, a front wall and a top wall having an area substantially equal to that of said opening to cover said opening when said housing is pivoted in a retracted position in said opening; said side walls, said front wall and said top wall being connected together for movement as a unit as the housing pivots about said first axis, each of said side walls having an elongate slot; a light projector mounted in said front wall; a transverse rod means supported on said cab and pivotable about a second axis, said rod means extending through and movable along the lengths of said elongate slots of said side walls; and rod actuating means for causing the pivotal movement of said transverse rod means about said second axis such that upon actuation of said acutating means, said transverse rod means moves in said elongate slots causing the pivotal movement of said housing about said first axis, resulting, in one direction in said slots, in retracting said housing in said cab and, in the opposite direction, in raising said housing out of said cab.
Claim 2
Dependent Claim
242 words
A retractable head lamp assembly for use in combination with a lightweight vehicle having a cab at the front thereof, said cab having an opening on the top face thereof, comprising: a housing mounted in said cab and pivotable about a first axis to be moved in and out of said opening; said housing including a pair of opposite side walls, a front wall and a top wall having an area substantially equal to that of said opening to cover said opening when said housing is pivoted in a retracted position in said opening; said side walls, said front wall and said top wall being connected together for movement as a unit as the housing pivots about said first axis, each of said side walls having an elongate slot; a light projector mounted in said front wall; a transverse rod means supported on said cab and pivotable about a second axis, said rod means extending through and movable along the lengths of said elongate slots of said side walls; and rod actuating means for causing the pivotal movement of said transverse rod means about said second axis such that upon actuation of said acutating means, said transverse rod means moves in said elongate slots causing the pivotal movement of said housing about said first axis, resulting, in one direction in said slots, in retracting said housing in said cab and, in the opposite direction, in raising said housing out of said cab.
Claim 3
Dependent Claim
41 words
A retractable head lamp assembly according to claim 1, said side walls being generally parallel to each othe and generally perpendicular to said front wall, and said top wall lying across the top of the front wall and said side walls.
Claim 4
Dependent Claim
67 words
A retractable head lamp assembly according to claim 2, said slots in the side walls being aligned with each other in a direction transverse to the planes of the parallel side walls, said rods having aligned ends and a U-shaped central portion, the ends of said rods being pivotably mounted in the cab, and the bottom of the U-shaped central portion extending through and between said slots.
Claim 5
Dependent Claim
40 words
A retractable head lamp assembly according to claim 2, the dimensions of said top mating with the said openings so that the top is flush with the top face of the cab when the housing is pivoted into the cab.
Claim 6
Dependent Claim
67 words
A retractable head lamp assembly as defined in claim 1, further including spring means having one end secured to said transverse rod means and the other end secured to said front wall for assisting the pivotal movement of said transverse rod means and for maintaining said transverse rod means in their respective positions when said light projector is in the retracted position and in the open position.
Claim 7
Dependent Claim
25 words
A retractable head lamp assembly as defined in claim 5, including means for adjusting the relative position of said light projector to said front wall.
Claim 8
Dependent Claim
64 words
A retractable head lamp assembly as defined in claim 1, wherein said rod actuating means include a control rod, having one end mounted adjacent the driver station of the vehicle, and a link member pivotally receiving the other end of said control rod at one end thereof and being rigidly fixed to one extremity of said transverse rod means at the other end thereof.
