Abstract: An adapter for attaching an accessory, such as a light, to a partition frame is disclosed. In one form, the adapter includes two opposed brackets. Each bracket has a base, a side wall extending downwardly from the base, a flange extending inwardly from the side wall, and a wall extending upwardly from the base. The brackets may be installed to the partition frame by inserting the flange of each bracket in a slot in the side of the partition frame. When the brackets are installed to the partition frame, a post structure including the upright walls is formed. The post structure is used for attaching the accessory. In another form, the adapter includes a post and a support member. The support member may mounted to the partition frame or to a mounting bracket attached to the partition frame. The post may be used for attaching the accessory.

Abstract: A floor tile assembly comprises a floor panel supported above a floor surface by at least one frame member, wherein the floor panel includes an aperture, and an insert assembly including a first plate including a top surface, a bottom surface and a side edge having a first indentation, wherein the first plate covers at least a portion of the aperture. A second plate is adjacent to the first plate and includes a top surface, a bottom surface and a side edge located adjacent the side edge of the first plate, wherein the second plate covers at least a portion of the aperture and a side edge of the second plate cooperates with the first indentation of the first plate to form a first opening. A structural reinforcement member is connected to the bottom surface of the first plate and abuts the bottom surface of the second plate, thereby reinforcing the first and second plates against vertically applied loads.
