  • Patent number: 6890043
    Abstract: An upright storage cabinet has a lock assembly which operates a vertically movable lock bar to simultaneously lock all drawers of the cabinet. The lock assembly includes a rotatable cam body which has a resiliently deflectable cam that projects radially therefrom. The cam body is rotatable between a locked position wherein the cam rotates a drive element to vertically displace the lock bar into engagement with the drawers, and an unlocked position wherein the cam allows the drive shaft to return to an initial position which disengages the lock bar from the drawers. The cam generates a driving force on the drive shaft during rotation of the cam body and is also resiliently deflectable to accommodate dimensional variations which varies the radial position of the drive shaft relative to the drive element.

  • Publication number: 20040100165
    Abstract: The invention relates to interlocks for file cabinets and the like which generally prevent more than one drawer from being opened at a given time. The interlocks include an elongated, flexible member, such as a cable, which is changeable from a high slack condition to a low slack condition. In the low slack condition, the interlocks prevent their associated drawers that are closed from being opened. In the high slack condition, the interlocks allow their associated drawer to be opened. The interlocks may be used in conjunction with a lock that selectively changes the cable from a high slack condition to a low slack condition and vice versa. The interlocks may be constructed to exert a force on the cable that is a small fraction of the pulling force exerted on a locked drawer.

  • Patent number: 6736468
    Abstract: An article of furniture having a set of lockable drawers, a vertically-actuated lock rod, which has a plurality of extending lock members, and a plurality of dog members. Each of the dog members is coupled to a sidewall of an associated drawer and includes a resilient trailing portion. When the lock rod is positioned in an unlocked position, the lock members and the dog members do not cooperate to inhibit the movement of the drawers. When the lock rod is positioned in a locked position, the lock members are positioned horizontally in-line with the dog members. Contact between a lock member and the trailing edge of a dog member inhibits the opening of a drawer. The resilient construction of the dog member permits the drawers to be closed when the lock rod is positioned in the lock position.

  • Patent number: 6511138
    Abstract: A mechanical system closes and latches one or more drawers in a multiple-drawer cabinet. Drawers which are slightly ajar are grasped by the latching mechanism, pulled fully closed, and locked shut. A latch finger engages a catch connected to the drawer and pulls the drawer closed. The finger is actuated by a crankshaft which, as it rotates, first lowers the latch finger to capture the catch, and then retracts the latch finger and with it the captured drawer. The crankshaft rotates to a position where any pull forces on the finger are nearly in line with the axis of the crankshaft and have little tendency to cause reverse rotation. The crankshaft is then retained in this position, effectively locking the drawer closed. Thus, any drawer which is left slightly ajar, and which may falsely appear to be latched, is subsequently closed and securely locked. The latching mechanism may be motorized or manually operated.

  • Patent number: 6082839
    Abstract: In a drawer control for a file cabinet, a latch member is adapted to rotate via a striker pin attached to the drawer from a release position to an engagement position when the drawer is about to be fully closed. The latch member is urged by a reversing spring which opposes the closing of a drawer until a neutral position adjacent to a fully closed position is reached, and once this neutral position is passed, the reversing spring assists the closing of the drawer to thereby provide a damping action to the drawer movement. Additionally, a moveable member extending across the latch members of the respective drawers can be moved by a cylinder lock so as to engage all the latch members to centrally lock all the drawers, and the moveable member is similarly actuated by opening of one of the drawers so as to interlock the movements of the drawers and permit only one of the drawers to be opened at a time.

  • Patent number: 5988778
    Abstract: An interlock assembly for use with two or more vertically arranged drawers mounted on telescopic slides in a housing such as a cabinet so as to prevent the extension of a drawer once another drawer is opened. The interlocking system interfaces with the stationary members of vertically arranged slides attached to the cabinet. A pair of opposing upper and lower actuator followers are slidably and transversely fitted near the front of the stationary members so that movement of one actuator follower toward the other, displaces the other. A rod connects the upper actuator follower of one slide with the lower actuator follower of a slide directly above it. An actuator is connected to the front ends of the telescopic members of the slides. As a telescopic member is extended, the actuator of that slide makes contact and displaces the upper actuator follower of the slide which results in the upper displacement of the lower actuator followers of the slides directly above the extended slide.

  • Patent number: 5944397
    Abstract: A multi-door enclosure for housing electrical equipment has a mechanical interlock device that interacts with a main primary door of the enclosure and the existing latch mechanisms of each of the remaining secondary doors to prevent such secondary doors from being opened unless the primary door is first opened. The interlock includes a lever arm that engages and is displaced by the primary door when closed. Such movement of the lever arm is transmitted via a mechanical linkage system to move one or more latch disabling members into disabling relation with the latch mechanisms of each of the secondary doors in order to retain the latch mechanisms in their latched positions and thereby lock the secondary doors in the closed position. Opening the secondary door allows the lever arm to return to its initial position which in turn retracts the latching members and allows unlatching and opening of the secondary doors.
