Abstract
The disclosed lateral transfer retroreflectors include three flat reflectors, two of them being united at right angles to form a hollow roof reflector, and a third being carried on a central member at the required offset distance from the roof reflector and in a plane perpendicular to each of the first two reflectors. The parts are related to each other in two embodiments which enable adjustment of the planes of the flat reflectors relative to each other without exacting requirements as to right-angled edges of any of the flat reflectors or as to parallelism of end faces of the central member.
Claims8
A hollow lateral transfer retroreflector, including first and second flat reflector plates disposed to form a roof reflector, a third flat reflector plate, and a central member having first and second opposite ends, each of the flat reflector plates forming the roof reflector being united along two essentially perpendicular edges thereof to said one end of said central member and to the other of said two plates, respectively, and said third flat reflector plate being united to said second end of the central member, the faces of said flat reflector plates being disposed in mutually perpendicular planes, said two edges of each of the roof reflector plates providing edge surfaces, only one of said two edge surfaces being in engagement with a surface of another part of the hollow lateral transfer retroreflector, enabling each said edge surface and said surface engaged thereby to be maintained in mutual contact and in condition to be united through a range of mutual angular adjustments of the roof reflector plates before the parts are united.
A hollow lateral transfer retroreflector, including first and second reflector plates having reflecting flat faces disposed to from a roof reflector, a third reflector plate having a reflecting flat face, and a central member, said third plate being united to a first portion of the central member and being disposed in relation to said roof reflector to constitute therewith a hollow lateral transfer retroreflector, a second portion of said central member spaced from said first portion having a mounting flat face parallel to the reflecting face of said third reflector plate, an edge of said second reflector plate abutting said mounting flat face, an edge of the first reflector plate abutting the reflecting flat face of said second reflector plate, and said mounting face having an edge abutting the reflecting flat face of said first reflector plate, each of said first and second reflector plates and said central member being united where they abut one another.
