  • Patent number: 7527335
    Abstract: An armrest structure includes a tubular support, and an armrest having a tubular end telescopingly engaging the tubular support. A support plate engages bottom walls of the tubular support and the tubular end in a laminar arrangement. A clamping bolt slides through a top hole and into aligned holes in the laminar arrangement, with its head abutting the aligned holes. A clamping handle on a bottom of the bolt is rotatable between a clamping position tensioning the bolt to secure the arrangement, and a release position de-tensioning the bolt. By this arrangement, remaining walls of the tubular support and the tubular end are not deformed even when the clamp is clampingly pressing the adjacent sidewall sections together. An adjustable back with actuator handles at a lower edge of the back, and a seat assembly with fingers that retain an upholstery cover tight against concave areas are also shown.

  • Patent number: 7210270
    Abstract: An elevated raceway for routing utility lines in a vertically spaced relationship above the upper edge of a partition. The raceway includes an elongated passageway configured to retain utility lines in a horizontally extending manner. A first support member extends downwardly from the raceway, and has a connector spaced apart from the raceway a first vertical distance. The connector is configured to attach to a partition frame. A second support member extends downwardly from the raceway, and has a connector spaced apart from the raceway a second vertical distance that is different from the first vertical distance, such that the raceway is supported at a generally uniform vertical height above an upper edge of a partition having sections with different heights.

  • Patent number: 6984320
    Abstract: The present invention provides a WTS closure assembly that is easily and quickly secured to and removed from the filter chamber of a WTS. The closure assembly of the present invention provides a bail handle attached to the closure and which utilizes a mechanical advantage, preferably in the form of a pivoting handle which presses a plurality of cams onto the WTS housing, thereby breaking a seal between the closure assembly and the WTS filter chamber, and lifting the closure away from the filter chamber.
