  • Patent number: 8250993
    Abstract: A storage assembly adapted to be secured to a work surface includes an enclosure defining an interior, wherein the enclosure is adapted to be secured around an opening in the work surface. A platform is disposed within the enclosure, and a cover is connected to the enclosure and configured to enclose the interior of the enclosure. The cover is movable between a closed position and an open position, wherein the cover in the closed position forms a top wall for the enclosure, and wherein the cover in the open position exposes the platform. A movement control arrangement is connected between the enclosure, the platform and the cover. The movement control arrangement and the enclosure have cooperating guide slot structure for receiving and guiding the platform, and enabling raising and lowering of the platform within the enclosure in response to movement of the cover between the open and closed positions.

  • Patent number: 8177174
    Abstract: A monitor lift mechanism that can be utilized in connection with a desk having a stationary work surface. The monitor lift mechanism is movable between a retracted position in which a monitor is positioned beneath the work surface, and an extended position in which the monitor is positioned above the work surface for viewing. The monitor lift mechanism includes a lift bar that is movable between a retracted position and an extended position through the use of a block and tackle pulley and lift cylinder arrangement. A latch mechanism holds the lift bar in the retracted position and can be released upon depression of a monitor door coupled to the lift bar.

  • Patent number: 7708347
    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.

  • Patent number: 7607180
    Abstract: A seating furniture assembly that is convertible from a first position to a second position has a seat member and a back member pivotably connected to the seat member. The back member is pivotable from a first position in which the back member extends upwardly from the seat member to form a seat, and a second position in which the back member overlies the seat member and faces upwardly to form a bed. Movement of the back member from the first position to the second position translates the seat member forwardly to provide wall clearance and a support in which the seat member supports a forward area of the back member when the back member is in the second position.

  • Patent number: 7571959
    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.

  • Patent number: 7278360
    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.

  • Patent number: 7096533
    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.

  • Patent number: 6979209
    Abstract: A pivoting utility receptacle assembly for use with a work surface, such as a desktop. The assembly includes a base member positionable within an opening in the work surface and a receptacle member that is pivotally mounted to the base member. A biasing member is engaged between the receptacle member and the base member, and biases the receptacle member to a partially exposed position with respect to the base member. The assembly also has a locking mechanism including a latch on the receptacle member which engages the base member and secures the receptacle member in a closed position with respect to the base member until such time as it is desired to expose the receptacle member. The movement of the receptacle member out of the base member under the influence of the biasing member is controlled by a movement controlling assembly engaged between the receptacle member and the base member.

  • Patent number: 6779856
    Abstract: A storage unit includes a cabinet defining an interior and a door assembly, which has a first door section and a second door section. Each of the door sections is pivotably mounted to the cabinet for movement between an open position and a closed position. The first and second door sections prevent access to the interior of the cabinet when in the closed position and provide access to the interior of the cabinet when in the oven position. The storage unit also includes a link pivotably interconnected between the first and second door sections so as to synchronize movement of the first and second door sections between the open and closed positions. A biasing arrangement counterbalances the door assembly and maintains the first and second door sections in both the open position and closed position and positions therebetween.

  • Patent number: 6644221
    Abstract: A folding sectional table assembly includes a pair of table sections, each of which includes a frame assembly and a table top. Each frame assembly includes inner and outer leg assemblies, and each leg assembly has an upper tubular member pivotably mounted at its ends relative to a pair of apron members secured to the underside of the table top, for providing pivoting movement of the leg assembly relative to the table top. A latch arrangement selectively maintains the table sections in the folded, storage position, and includes a latch member pivotably mounted to one of the table sections and a catch member stationarily mounted to the other of the table sections. A latch actuator is interconnected between the latch member and the apron members, for disengaging the latch member from the catch member when it is desired to move the table sections away from the folded, storage position.
