Abstract: First and second operable wall panel faces are positioned with respect to one another by vertical and horizontal brackets which include corner portions positioning the panel faces in compressed relation with vertical and horizontal flexible vinyl seals extending about the entire perimeter of the panel faces, so as to provide increased impact resistance, reduced noise transmission, and easier manufacture.

Abstract: An operable wall panel is fitted at its top with retractable load transfer bolts and at its bottom with a floor engagement member. The load transfer bolts are normally biased to engage the panel guide track, while the floor engagement member provides an acoustic gasket having a serrated edge for engaging the mating edge of a floor-mounted insert. A lever and cable system provides one-step retraction of both the load transfer bolts and floor engagement member.

Abstract: An operable wall system having a primary track and several storage tracks intersecting said primary track can be improved by the use of rotary switches at the intersections of the primary and storage tracks and by the use of a positioning structure carrying holders capable of being actuated so as to engage and disengage wall sections or panels being moved between said primary and said storage tracks. When such an operative wall structure is employed to move a wall section or panel on to the primary track from the storage tracks the panel to be moved is engaged by the holders and then these holders are moved through the movement of the positioning structure so as to place the section or panel being moved on to the switches. The holders are then disengaged from the panel or section and the switches are manipulated so as to allow the panel to be moved along the primary track. In storing panels the reverse of this series of operations is employed.

Abstract: An operable wall system which is especially desirable for use with large and/or heavy wall panels can be constructed so that each panel in the system is supported from a track structure by two separate trolleys. The track structure includes a terminal section having two parallel end sections joined to the main portion of the track structure through a junction. This junction is provided with cams which cooperate with differently oriented flange wheels on successive trolleys so that the panels can be moved between a position in which they are aligned with one another beneath the main portion of the track structure and a position in which they are suspended from the end sections and are located in side by side relationship.

Abstract: A suspension system primarily designed for use with operable walls and partitions can be constructed utilizing a plurality of identical tracks joined together in a system having a junction between such tracks and a trolley which is movable along the tracks and across the junction. Each of the tracks includes a pair of first spaced, parallel flanges and a second pair of spaced, parallel flanges located beneath the first pair. The trolley includes a bearing plate carrying a plurality of downwardly extending spherical bearings and a support plate located parallel to and underneath the bearing plate and the downwardly extending bearings. The trolley is adapted to be positioned in any of the tracks with bearings on the trolley supporting the trolley on the first pair of parallel flanges and with the support plate being located between the pairs of flanges.
