Abstract: A sectional parabolic reflector of improved construction comprising two similar parabolically curved half-reflector sections each having a longitudinal parabolic axis and a reflecting surface, a mount for said half-reflector sections, said mount and said half-reflector sections being separately formed, said mount and said half-reflector sections being formed for manual manipulation together at joints, said mount and half-reflector sections when manipulated together at said joints locking against movement of the half-reflector sections towards each other when they assume an operational position wherein their reflecting surfaces combine in a common parabolic surface, locking means extending between each of said half-reflector sections at a location spaced from said joints and for locking said joints to maintain said half-reflector sections with their reflecting surfaces in said operational position.

Abstract: The invention is a clip used to clip the edge of a web that forms a seat or back of a lawn chair having a tubular frame. The clip is made from a single piece of wire bent into a T-shape with a stem the T-stem having a hook and a C-shaped hole searching lead section which is designed to engage the inside wall of a tube in use to maintain the axis of a hook section extending in a forward direction.
