Abstract
The present invention is directed to a mounting member for use in a pulley assembly that is generally U-shaped and includes: (i) a side wall portion; (ii) a base portion; and (iii) a stiffness enhancement portion. The side wall portion is one vertical arm of the U-shape and serves to rotationally mount the pulley. The base portion is the bottom of the U-shape and is generally used to mount the to a structure (for example, a beam in a theatre). The stiffness enhancement portion is the other vertical arm of the U-shape and serves at least to enhance stiffness so that higher capacity pulley assemblies with unitary side plate/base plate members may be achieved.
