| Title: |
Shutter Lock for Specialized Lighting Fixtures |
| Abstract: |
A specialized lighting fixture, such as a framing projector provided with
a plurality of adjustable framing shutters, is modified to incorporate a
pair of locking rings, surrounding the body of the lighting fixture and
positioned on opposite sides of outwardly projecting portions of the
framing shutters. After initial adjustment of the framing shutters has
been completed, the locking rings are tightly compressed together, as by
locking screws positioned between adjacent pairs of framing shutters, to
lock the shutters in position against unintended dislodgment. For
lighting fixtures of non-uniform shape, the locking rings may be made in
two parts, preferably hinged together, which are secured together after
being positioned on the housing of the lighting fixture. The locking
rings are particularly adapted for retrofit installation on lighting
fixtures of existing design.
