Abstract: A trim for a fabric mounting track system as disclosed and claimed in the applicant's prior application, Ser. No. 441,990, filed on Nov. 16, 1982. The trim consists basically of a unitary substantially F-shaped structure having a flat trim portion. There is preferably a retaining portion extending at right angles to the trim portion, as well as an intermediate portion, also extending from the trim portion and at right angles thereto and spaced from the retaining portion. The retaining and intermediate portions are arranged to fit precisely over one of the hinge lock or back support plates of the track mounting system. The trim portion fits over the two plates to provide a pleasing appearance and to lend mechanical rigidity to the mounting track system.

Abstract: A hospital curtain track system utilizing a track switch which permits the use of a single privacy curtain selectively for each of a pair of adjacent bed cubicles. The switch and tracks are of two types, one type being a recessed system installable flush with the underside of and as an integral part of an original ceiling installation, and another type being surface mounted installable upward against the underside of an existing ceiling. Self splicing cubicle tracks provide easy assembly and versatility in space planning. One track switch unit between each two bed environment splices directly with the cubicle track and eliminates extra connecting parts including one complete track leg resulting in minimal installation time and expense. The switch utilizes a pull-chain actuated toggle for shifting a horizontally shiftable switch section into alignment with the desired curtain track.
