  • Patent number: 11076699
    Abstract: A movable tablet for use with a chair is disclosed. The movable tablet is part of a mounting assembly that allows the tablet to be used with different types of chairs. The mounting assembly includes a stationary pivot rod and an outer housing that surrounds the pivot rod. A lower bearing is positioned between the outer housing and a mounting plate secured to a back face of the tablet. A guide hub of the lower bearing travels within a guide track on the mounting plate secured to the tablet to limit the pivoting movement of the tablet. An upper bearing is positioned between the mounting plate and the tablet such that the upper and lower bearings are positioned between metallic elements of the mounting assembly. A friction disc is positioned within the mounting assembly to control and adjust the pivoting movement of the tablet relative to the stationary pivot bar.

  • Publication number: 20080041281
    Abstract: A desk system with power and/or communication capability includes a series of interconnected desk sections. Each desk section includes a pair of leg that support a worksurface, and one or more stanchions extend upwardly from the worksurface. A primary power distribution system is located below the worksurface. The primary power distribution system includes receptacles mounted to a beam that extends between the pair of legs. Openings are formed in the legs for enabling the primary power distribution system to pass from one desk section to another. Each stanchion defines an open interior and is mounted above an opening formed in the worksurface. Each stanchion includes a mounting plate, and one or more power and/or communication supply blocks are adapted for securement to the mounting plate. Flexible cords or cables extend from each mounting block through the opening in the worksurface, and are plugged into the receptacles or the primary power distribution system located below the worksurface.

  • Publication number: 20070182222
    Abstract: A student desk includes a base that supports a seat and a worksurface. The base includes transverse front and rear base members, with a central base member extending therebetween. A worksurface support and a seat support are mounted to and extend upwardly from the base, and the worksurface and seat are mounted to the worksurface and seat supports, respectively, so as to be adjustable in elevation. Casters are mounted to the front and rear transverse base members to facilitate movement of the desk on a support surface such as a floor. Certain of the casters may be constructed so as to lock in position when the desk is occupied. The seat includes a handle area, so that the desk can be quickly and easily repositioned in a classroom with minimal effort.

  • Publication number: 20060186718
    Abstract: An article of seating furniture includes a base, a seat and a back. The back includes a reclining mechanism. The seat is interconnected with the reclining mechanism such that reclining movement of the back moves the seat forwardly and upwardly. When the back is fully reclined and the seat is fully raised, an upper surface of the seat is coplanar with an upper surface of the back. A footrest is movable between a retracted position and an extended position. When extended, the footrest is generally coplanar with the seat. The back includes a spine having a lower end pivotably interconnected with the base. The spine includes a seat mounting extension to which the seat is pivotably mounted. Mounting links between the seat and the base provide movement of the seat when the back is reclined.

  • Publication number: 20050273973
    Abstract: A locking roller assembly includes a housing adapted for mounting to an article of furniture. A wheel is rotatably mounted to the housing via a mounting arrangement that accommodates relative vertical movement between the wheel and the housing. The wheel is mounted to an axle, which in turn is secured to an axle carrier. A biasing member, such as a spring, is engaged between the housing and the axle carrier to bias the housing toward a raised position. When a load is applied to the article of furniture, the spring is compressed so as to allow the housing to move vertically downward toward the wheel. The housing includes an engagement surface that engages the wheel when the load is applied and the housing is moved downwardly, to prevent rotation of the wheel and to thereby prevent movement of the article of furniture.
