Abstract: An apparatus and method is provided for mounting a support column to a chair base having a cavity formed therein and tilt-control housing having a hub defining a core. The support column has a top portion and a bottom portion. The apparatus includes a support structure, a vertical shaft and a mass positioned within a vertical housing. In operation, the base is supported by the support structure. The bottom portion of the support column is placed in the cavity of the base and the hub of the tilt-control housing is placed on the top portion of the support column. An impact force is applied against the tilt control housing to simultaneously press fit the top portion of the support column within the hub and the bottom portion of the column within the cavity.

Abstract: A cart for transporting materials along a floor having a base positioned parallel to the floor. Positioned above the base is a rectangular cover having a first side edge, a second side edge and a back edge defining three sides of a rectangle. A first side support, a second side support and a back support each extend from the base to the cover. Four vertical supports extend from the base to contact the cover at four points substantially aligned with a first diagonal of the rectangle.

Abstract: An adjustable arm rest assembly for use on a chair including a support member, an arm rest member, a locking element and an adjustment member. The support member is attached to the chair and extends substantially upward therefrom. The arm rest member extends substantially coaxially with the support member. The locking element is attached to one of the support member and the arm rest member. A projecting portion extends from an end portion of the locking element and includes a first mating element. The adjustment member is attached to the other of the support member and the arm rest member. The adjustment member and the locking element are movable with respect to one another. A plurality of vertically spaced flanges form a plurality of recesses within the adjustment member. Each recess is sized to receive the projecting portion of the locking element and has a second mating element corresponding to the first mating element.

Abstract: A device for adjusting the backrest of a chair to any of a plurality of locked positions comprising a continuous track formed in one member and a slot formed in a second member that is slidable relative to the first member. A locking pin follows along the track and traverses across the slot as the backrest is raised and lowered in the process of moving the backrest to its series of locked positions. The locking pin must circumnavigate the continuous track to complete the adjustment cycle and the person doing the adjustment has a feeling of control and confidence that the adjustment process is progressing properly throughout the adjustment cycle.

Abstract: A mechanism is provided for adjusting the height of the backrest relative to a chair seat. The adjustment mechanism for releasably retaining the backrest in a plurality of selected positions relative to a seat permits the chair to be shipped in a "knocked down" condition and easily assembled by the consumer. The adjustment mechanism includes a channel member that is secured to the backrest, and a support member carried by the chair that is slidably received in the channel member and rigidly locked in selected positions. The support member has vertically aligned rack teeth and the backrest has a movable catch having pawls that are adapted to engage the rack teeth. Movement of the catch places the pawls into engagement with the rack teeth to prevent the downward movement of the backrest from a selected vertical position.

Abstract: A lock system for a container having a first side wall and a second side wall. The lock system comprises a first component supported on a first track which defines a path for the first component to move from a closed position to an open position. The lock system comprises a first locking bar movable from a first position to a second position allowing the first component to move along the first track to the open position. The lock system comprises a second component supported on a second track defining a path for the second component to move from a closed position to an open position. A second locking bar is movable from a first position to a second position allowing the second component to move along the second track to the open position.

Abstract: There is disclosed an electrified wall panel system having a power distribution server locatable within a wall panel unit. The power distribution server has four receptacle module ports oriented in an H-shaped configuration in which a first receptacle port on a first side of the wall panel unit opens toward a first end of the wall panel unit, a second receptacle port on the first side of the wall panel unit opens toward a second end of the wall panel unit, a third receptacle port on a second side of the wall panel unit opens toward the first end of the wall panel unit, and fourth receptacle port on the second side of the wall panel unit opens toward the second end of the wall panel unit. First and second harnesses are each electrically connected at first ends thereof to the power distribution server, extend to opposite ends of the wall panel unit, and include connector ports on the second ends thereof for providing electrical interconnection of adjacent wall panel units.

Abstract: An apparatus is provided for adjusting the position of a backrest relative to a chair seat. The backrest includes an elongated stem having a curved lower portion. Preferably, a spring operably engages the stem to bias it in an upward direction. A housing is adapted to slidably receive the curved portion of the stem and guide the spring. A latch mechanism is adapted to engage the stem to lock the backrest in a desired position, and an actuator member is adapted to move the latch mechanism between an engaged and disengaged position. In operation, the latch mechanism is disengaged to allow the backrest stem to move in a curvilinear path to a desired height and corresponding angular position, and reengaged to lock the backrest stem in said position.

Abstract: A raceway cable retention and accommodation apparatus which has a support surface and a bracket. The bracket comprises a mounting portion, a first leg connected to the mounting portion, a second leg connected to the first leg, and a third leg connected to the second leg. The mounting portion and the first, second, and third legs are configured so as to define a J-shaped structure. The bracket is attached to the support surface by a mounting device. A panel for a panel system which has five surfaces. The panel has a first surface, a second surface connected to the first surface, and a third surface connected to the second surface. Furthermore, the panel has a fourth surface connected to the third surface and a fifth surface connected to the fourth surface. The panel is configured such that the first and second surfaces are mirror images of the fourth and fifth surfaces with respect to a plane which is perpendicular to the third surface.

Abstract: A lock assembly for locking a door to a frame element, comprising a rotatable locking element and a locking rod connected to the rotatable locking element. Rotation of the locking element in one sense results in the locking rod moving toward a first side of the frame element and rotation in the other sense results in the locking rod moving away from the first side of the frame element. The lock assembly also comprises a pin having a first end and a second end, wherein the first end selectively engages the rotatable locking element at an engagement position so that the locking element is prevented from rotating. The lock assembly comprises a pin actuating mechanism for moving the pin from the engaged position to a disengaged position wherein the pin does not engage the locking element.

Abstract: A work station particularly adapted for use in a uniform open floor plan. The work station has a horizontal work surface having a front edge and a rear edge, a support member for supporting the horizontal work surface, a first trough located in an area beneath the horizontal work surface, and a second trough at a location displaced vertically below the first trough whereby the first and the second troughs define separate substantially horizontal passageways for the laying-in of cabling. In a further aspect, there is provided an office furniture system comprising a plurality of like work station modules aligned along a linearly extending course, each work station module occupying substantially the same area.
