Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
126 words
In a flash attachment comprising a body, mounting means connected to said body for fixedly securing said flash attachment to a camera, said body containing a discharge circuit and power supply means for providing electric charge to said discharge circuit, a flash head including a light-emitting discharge element; the improvement of an extendable member connecting said flash head and said body, said extendable member defining a longitudinal axis running between a first point at which said extendable member connects to said body and a second point at which said extendable member connects to said flash head, said extendable member being selectively extendable along said longitudinal axis, and conducting means electrically connecting said body and said flash head for supplying electric charge to said light-emitting discharge element.
