  • Patent number: 6851226
    Abstract: A freestanding partition panel for dividing a floor space includes a rigid partition frame having vertical side frame members and first and second horizontal frame members extending between the vertical side frame members to form a vertically enlarged opening through the frame, and an open space within the panel. At least one intermediate horizontal cross member extends across the vertically enlarged opening and defines upper and lower openings through the frame. The intermediate cross member and at least a selected one of the first and second horizontal frame members include a plurality of horizontally spaced apart attachment locations defining a plurality of discrete, serially adjacent mounting spaces. The partition panel further includes a utility unit that is mountable in a selected one of the mounting spaces.

  • Patent number: 6748710
    Abstract: A partition and wall system includes a partition with trim piece(s) securely attached to a top edge and vertical side edges of the partition. One or both of the trim piece(s) have a T-slot running along their length, to which accessories can be secured by use of T-fasteners that extend into the slot and engage blind surfaces at a bottom of the slot. The accessories include such things as screens, hooks, lights, panels, shelves, wire managers, utility-using devices, and the like, and can be easily arranged by office workers in optimal and customized arrangements, thus improving efficiency and adding function and value to the office arrangement.

  • Patent number: 6701677
    Abstract: A partition includes a partition frame having a face and a cavity behind the face, and a covering attached to the partition frame that aesthetically covers the face. The covering includes an access slit through which the cavity can be accessed, and is sufficiently flexible so that the slit can be opened to access the cavity. A pouch can be attached to the covering material along the slit, so that a purse-like pouch is created for holding personal items and/or excess electrical wiring. A zipper or closure device can be used on the access slit. In one form, the skin is releasably attached with hook-and-loop material, so that a corner of the skin can be pulled loose for accessing the cavity.

  • Publication number: 20030183349
    Abstract: A partition includes a top edge and vertical end edges covered by trim pieces. One or more of the trim pieces include an elongated base member made of durable material, such as metal, with side flanges defining a longitudinal channel. A strip insert is positioned in the channel where it is protected by the side flanges. When both top and end edges of a partition are covered, the end of one protrudes across an end of the other, with the side flanges of the protruding portion being radiused to prevent formation of a sharp corner. The insert can be aesthetic, such as wood, brushed metal, painted sheet, plastic, or light-transmissive glass or plastic, or the insert can be functional, such as tackable material, erasable markerboard material, a light-transmissive “light-pipe” material, or a mating “U” channel defining a hidden passageway on the base member for wire management.

  • Publication number: 20030182871
    Abstract: A prefabricated system for outfitting a building space includes an architectural product (such as a full-height permanent building wall, a post-and-beam product with overhead frame, and a drywall-covered wall), a furniture product (such as a partial-height wall, a partition, and a desking system), and a plurality of accessories. The architectural product includes a structural member with horizontal and vertical accessory-mounting T-slots, and the furniture product includes structural trim pieces with identical vertical and horizontal accessory-mounting T-slots. The plurality of accessories are constructed to stably engage any of the accessory-mounting slots at a selected location along the slots. Some accessories can be attached to and extend between the two products, such as an accessory screen that extends between a post of a post-and-beam system and an end of a partition system.
