Retro-reflective marker
View Patent ↗The present application relates to a reflector body ( 10 ), particularly a spherical retro-reflective marker, comprising a plurality of reflector body segments ( 11 ), and the individual reflector body segments ( 11 ) comprised by such a reflector body ( 10 ), and methods for producing the reflector body segments ( 11 ) and the reflector body ( 10 ). The reflector bodies ( 10 ) comprise a coating having a reflection film ( 12 ), by which the reflector body segments ( 11 ) of the reflector body ( 10 ) are uniformly spanned, performed by suitably selecting the geometric shape of the reflector body segment ( 11 ) to be spanned, by injecting molding behind the reflection film ( 12 ) in an injection molding process and/or by producing the reflector body segments ( 11 ) in a forming process.
1. Reflector body which forms a marker, comprising one or more reflector body segments, wherein each reflector body segment has a coating which comprises a reflection film which, by itself on a single surface, reflects light directly back to a source of said light in a direction substantially parallel to incident light from said source, and producing each reflector body segment in an injection molding process, comprising the steps of:
providing an injection mold with a contact element, which has a contact surface, which defines a cavity of the injection mold in an area, and an injection orifice,
injection molding behind the reflection film by injecting a molding material through the injection orifice into the cavity.
2. Reflector body according to claim 1 , wherein the reflector body has a substantially spherical reflection surface.
3. Reflector body according to claim 2 , wherein the reflector body has two hemispherical elements, wherein one hemispherical element has at least one reflector body segment and the other hemispherical element has at least two reflector body segments.
4. Reflector body according to claim 2 , wherein the reflector body has a sphere segment-shaped base segment with an adapter receptacle,
wherein the base segment has at least one reflector body segment, and
wherein the reflector body furthermore has at least two further reflector body segments, which together with the sphere segment-shaped base segment form a spherical shape.
5. Reflector body according to claim 1 , wherein the reflector body segments are connected to each other by at least one of:
form-fitting,
friction-fitting,
bonding and
welding.
