Abstract
Abstract An illuminating reflector is composed of a stick which is adapted to be detachably inserted into a stick holding aperture formed in an illuminator, an actuating runner which pivotally connects a plurality of dome ribs and is slidably inserted onto the stick, a reflection sheet which is put on the ribs and cause diffusingly reflection of light, a fixed collar secured at the top portion of the stick, and struts which are pivoted at their opposite ends respectively to the fixed collar and to the midway of the ribs. Therefore, the reflector can be opened by displacing the runner toward the fixed collar to flare the reflection sheet in a shape of a box, while when removing the runner counterwardly, the reflector can be folded into a compact form. The reflector further comprises a flexible cover which is provided in succession to a narrow end of the reflection sheet and to the flared open end of the reflection sheet being attached a light permeable diffuser screen so that an illuminant of the illuminator is accommodated within the box-shaped reflector.

Claim 1
Independent Claim
328 words
An illuminating reflector which comprises: (a) a stick having a rearward end and a forward end, the rearward end of said stick being adapted to be detachably inserted into a stick holding aperture in an illuminator; (b) an acuating runner slidably disposed on said stick; (c) means for selectively fixing said actuating running in either a first position on said stick or in a second position on said stick, said first position being forward of said second position; (d) a plurality of dome ribs each of which has a rearward end and a forward end, the rearward end of each of said plurality of dome ribs being pivotally connected to said actuating runner; (e) a fixed collar secured to the forward end of said stick; (f) a plurality of struts each of which has a rearward end and a forward end, the forward end of each said plurality of struts being pivotally connected to said fixed collar and the rearward end of each plurality of struts being pivotally connected to a corresponding one of said plurality of dome ribs intermediate the rearward and forward ends thereof; (g) a flexible reflection sheet having a forward end and a rearward end, said flexible reflection sheet being mounted on said plurality of dome ribs; (h) a flexible cover having a forward end and a rearward end, the forward end of said flexible cover being attached to the rearward end of said flexible reflection sheet and the rearward end of said flexible cover being adapted to prevent light from the illuminator from leaking out rearwardly; and (i) a diffuser screen detachably attached to the forward end of said flexible reflection sheet, whereby, when said actuating runner is fixed in its first, forward position, said struts force said plurality of dome ribs outwardly, opening the illuminating reflector, and when said actuating runner is fixed in its second, rearward position, said struts pivot inwardly and rearwardly and said dome ribs pivot inwardly and forwardly.
Claim 2
Dependent Claim
328 words
An illuminating reflector which comprises: (a) a stick having a rearward end and a forward end, the rearward end of said stick being adapted to be detachably inserted into a stick holding aperture in an illuminator; (b) an acuating runner slidably disposed on said stick; (c) means for selectively fixing said actuating running in either a first position on said stick or in a second position on said stick, said first position being forward of said second position; (d) a plurality of dome ribs each of which has a rearward end and a forward end, the rearward end of each of said plurality of dome ribs being pivotally connected to said actuating runner; (e) a fixed collar secured to the forward end of said stick; (f) a plurality of struts each of which has a rearward end and a forward end, the forward end of each said plurality of struts being pivotally connected to said fixed collar and the rearward end of each plurality of struts being pivotally connected to a corresponding one of said plurality of dome ribs intermediate the rearward and forward ends thereof; (g) a flexible reflection sheet having a forward end and a rearward end, said flexible reflection sheet being mounted on said plurality of dome ribs; (h) a flexible cover having a forward end and a rearward end, the forward end of said flexible cover being attached to the rearward end of said flexible reflection sheet and the rearward end of said flexible cover being adapted to prevent light from the illuminator from leaking out rearwardly; and (i) a diffuser screen detachably attached to the forward end of said flexible reflection sheet, whereby, when said actuating runner is fixed in its first, forward position, said struts force said plurality of dome ribs outwardly, opening the illuminating reflector, and when said actuating runner is fixed in its second, rearward position, said struts pivot inwardly and rearwardly and said dome ribs pivot inwardly and forwardly.
