  • Patent number: 5400560
    Abstract: An element of an office panel includes a back support member closed at either end by molded end pieces. The molded end pieces in combination with the back support member define a front opening recess into which a filler material is inserted. A decorative facing material is applied over the filler material and attached to the back support member and the molded end pieces, whereby the facing material forms a finish face of the element. With this arrangement, the back support member is more easily manufactured, as it is open at either end and the molded end pieces can easily be inserted within the back support member to effectively close the member and provide a complete support for the element. According to an aspect of the invention, the molded end pieces include molded components thereon by means of which the element can be effectively supported by an office panel frame.

  • Patent number: 5022316
    Abstract: A newspaper bundler comprises a rigid frame assembly (FIGS. 1 and 2) for enabling newspapers to be easily stacked into a pile (12). The frame includes a U-shaped crosswise holder (14) whose upstanding opposing side arms are made of sheet metal or plastic channels (22). A stack of paper bundling straps (26) is positioned on the crosswise portion. The channels each have a pocket for holding fan-folded end portions (30) of the stack of paper straps. One end portion of each strap is coated with adhesive (32) so when the end portions of a strap are pulled from their pockets, they can be attached together around the pile of papers to securely bundle them so that they can be carried easily with one hand (FIG. 5). The entire bundle is recyclable at a paper mill. In lieu of sheet metal side channels with pockets, the side pockets can be formed of tubular members (FIG. 6) bent and shaped to form pockets for the fan-folded ends of the straps.

  • Patent number: 5013112
    Abstract: An office panelling system is advantageously combined with fiber optic communication cable wherein the panels of the system are generally open in the center thereof and the vertical space of the panel is advantageously used for reducing the curvature of the cable between panels disposed at an angle. The panels have a metal framework onto the sides of which cover members are secured such that the interior of the framework is generally open. The framework includes a host of distributed passage ports therethrough for allowing communication cables and the like to pass through the framework where desired.

  • Patent number: 4942805
    Abstract: A modular office panelling system has been improved by providing an air circulation arrangement of selectively cool or remove heat from a particular area defined by the panelling system. Fans are provided in removable panel cover portions which can advantageously be secured in the office panelling system in the same manner as fabric covered removable cover portions. Thus, the air circulation arrangement may be provided as an original specification or added as a retrofit in the field. The interior of the panel is also used as a large inlet plenum whereby the flow of air into the panel is at a slow velocity.

  • Patent number: 4881349
    Abstract: Securement and cooperation between panels of an office panelling system is improved by mechanically connecting panels in a manner to maintain a particular orientation and to allow transfer of loads therebetween. The mechanical fasteners are advantageously combined with compressible strips between panels which not only deform during fastening of the fasteners, but engage the panel and distribute the clamping force to a larger area thereby adding structural rigidity.
