Abstract: A bracket system for mounting a support rod, such as a closet rod, a shower curtain rod, a towel bar, or the like, between two support surfaces. The bracket system includes a bracket member and a cover member. The bracket member includes a base portion and a rod support member. The rod support member includes a support portion that supports the support rod and a spring portion that facilitates coupling of the bracket member to the cover member. The spring portion is compressed or deformed and then the cover member is slid over the spring portion. Upon release of the compression on the spring portion, the spring portion exerts an outward restoring force onto the cover member to couple the cover member to the bracket member. The support rod is supported by the support portion of the rod support member and extends through an opening in the cover member.

Abstract: A collapsible ladder having rungs of a relatively strong and thin material with integral stand-off projections that allow the ladder to be safely descended and of a cross-section that allows the ladder rungs to nest to a high degree of compactness. The ladder is readily deployed by means of a cover having two sets of temporary fasteners. In an emergency, the ladder is deployed by partially unwrapping the cover to a first state which allows an attaching member to be removed and placed over a window sill. After insuring that narrow fabric supports, which attach the attaching member to the rungs, are not twisted between the attaching member and a top rung of the ladder, the multiple rungs (still wrapped by the cover and secured by a second set of temporary fasteners) are supported using a handle attached to the cover. The handle is then held outside the window and dropped.
