Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
177 words
An ultraviolet ray projector device for use in curing paint which comprises: an elongated reflector; a tubular ultraviolet lamp disposed in said reflector; an elongated casing having an opening port in one side, said reflector and said ultraviolet lamp being disposed in said casing; a truck frame, said casing being attached to said truck frame; a pair of main wheels rotatably attached to said truck frame, said pair of main wheels having a first common axis of rotation; at least one elongated support member having a first end and a second end, said first end being pivotably attached to said truck frame, said elongated support member pivoting about a second axis which is parallel to said first axis; and at least one sub-wheel rotatably attached to said second end of said elongated support member; whereby the elevation angle of the ultraviolet rays produced by said tubular lamp relative to a work surface and the distance from said tubular lamp to said work surface is controlled by pivoting said elongated support member about said second axis of rotation.
Claim 2
Dependent Claim
177 words
An ultraviolet ray projector device for use in curing paint which comprises: an elongated reflector; a tubular ultraviolet lamp disposed in said reflector; an elongated casing having an opening port in one side, said reflector and said ultraviolet lamp being disposed in said casing; a truck frame, said casing being attached to said truck frame; a pair of main wheels rotatably attached to said truck frame, said pair of main wheels having a first common axis of rotation; at least one elongated support member having a first end and a second end, said first end being pivotably attached to said truck frame, said elongated support member pivoting about a second axis which is parallel to said first axis; and at least one sub-wheel rotatably attached to said second end of said elongated support member; whereby the elevation angle of the ultraviolet rays produced by said tubular lamp relative to a work surface and the distance from said tubular lamp to said work surface is controlled by pivoting said elongated support member about said second axis of rotation.
Claim 3
Dependent Claim
41 words
An ultraviolet ray projector device for use in curing paint as recited in claim 1, wherein: said casing is attached to said truck frame such that an axis passing through said tubular lamp is parallel to said first axis of rotation.
Claim 4
Dependent Claim
41 words
An ultraviolet ray projector device for use in curing paint as recited in claim 1, wherein; said casing is attached to said truck frame such that an axis passing through said tubular lamp is perpendicular to said first axis of rotation.
Claim 5
Dependent Claim
60 words
An ultraviolet ray projector device for use in curing paint as recited in claim 1, wherein said reflector comprises: a pair of mirrors, said mirrors each being rotatable about axes parallel to an axis passing through said tubular lamp; and means for rotating said pair of mirrors such that said mirrors alternately form a reflective surface and a shutter mechanism.
Claim 6
Dependent Claim
25 words
An ultraviolet ray projector device for use in curing paint as recited in claim 1, which further comprises: driving means fo propelling said main wheels.
