Abstract: An anti-tip linkage mechanism for vertical file cabinets of the type having drawers and/or pivotal front panels includes molded polymeric cam follower housings that snap-fit onto each of the slide channels for the drawers or panels and non-circular connecting rods attached to cam actuators that enable interaction of the anti-tip mechanisms incorporated with each slide channel. Lock actuated auxiliary cam mechanisms and panel locking assemblies controllable by a single cabinet lock are connected with a cabinet lock by linkage bars or cables.

Abstract: A drawer slide includes a first slide channel telescopically mounted for longitudinal movement in a second slide channel. The first channel includes a cantilever spring latch which engages the second slide channel when the first slide channel is extended to a fully telescoped position associated with a fully open drawer supported by the first channel. The first slide channel further includes a longitudinally movable manual release lever, which is slidable to engage and release the spring latch and thus allow the first channel to be slidably translated into the second channel thereby allowing the attached drawer to be moved to the closed position. The first slide channel further includes a second cantilever spring latch that limits the opening movement of the first channel. Both spring members may be released by an auxiliary release lever.

Abstract: A locking and release mechanism for a slide assembly comprised of multiple telescoping channel members interacting, opposing cantilever springs mounted on the telescoping slides or channel. The mechanism can be made of plastic, spring steel or other alternative materials. The mechanism can be used on ball bearing or friction telescoping drawer slide assemblies.

Abstract: A storage and security case for a personal computer comprises a housing with fold over side platforms, which operate a mechanism to raise and lower a support platform within the case to cover a personal computer stored within the case or expose the personal computer. The side platforms provide additional functions such as a storage tray for various materials and a mouse platform.

Abstract: An improved brake and tilt adjustment control mechanism for a keyboard support platform includes a telescoping shaft connect between the keyboard platform and a housing supported on linkage arms that support the platform and connected the platform to a desk or support surface. The shaft is engaged by an encircling coil spring retained in the housing to lock the mechanism. Flexing the spring release locking mechanism and permits adjustment of the tilt or attitude of the keyboard platform to the linkage arms.

Abstract: A keyboard support arm assembly includes the keyboard platform having a planar surface and upon which is projected a virtual keyboard the projection being by means of a projection device having virtual image capability and having the capability of reading on a site-by-site basis the position and existence of or status of any manual digit input signal.

Abstract: A drawer slide assembly has at least three telescoping slide channels, including an outer channel, an intermediate channel and an inner channel. A mechanism is provided to control the sequential movement of the channels between the open and closed positions including a retention lock between the two inner most channels which is released upon sliding movement of those channels together toward the open position and engagement of a lever mounted on the intermediate channel with a raceway of the outer channel to thereby release the inner channel.

Abstract: There is disclosed an improved rotatable cylinder lock having a removable lock core. The lock core is removable from the lock housing for locking applications that require the lock to have up to 180° of lock core rotation. The invention is accomplished through the use of a specially designed lock housing, lock core, adapter, and shifter. The lock housing has a cylindrical opening defining a groove and rotational slot. Inserted within the cylindrical opening in the lock housing is an adapter having a stop lug and tumbler block, a shifter having a drive slot, and a lock core having a block restrictor relief. In use, the stop lug on the cylindrical adapter rotatably engages with the rotational slot in the housing while the tumbler block on the adapter rotatably engages with the block restrictor relief on the lock core. The assembly of the present invention thereby permits the lock core to be rotated 180° within the lock housing while also permitting the removal of the lock core.

Abstract: An improved brake and tilt adjustment control mechanism for a keyboard support platform includes a telescoping shaft connect between the keyboard platform and a housing supported on linkage arms that support the platform and connected the platform to a desk or support surface. The shaft is engaged by an encircling coil spring retained in the housing to lock the mechanism. Flexing the spring release locking mechanism and permits adjustment of the tilt or attitude of the keyboard platform to the linkage arms.

Abstract: A panel lock includes a housing with a pivotal face plate arranged to engage a bolt upon pivotal movement of the face plate. A rotatable plug assembly may be rotated between a locking and unlocking position to restrain or release the push plate.

Abstract: An adjustable hanging file system for a drawer having side panels utilizes frame members comprised of spaced skirts with a connecting crown to thereby define a u-shaped cross section and bracket members inserted between the skirts to support the frame members. Additional hanging bracket members incorporated with cross rail frame members support the cross rail frame members on frame members attached to a file drawer.

Abstract: A customer key actuated lock includes a retention mechanism which prevents counterrotation of the customer key plug to roation from the locked position toward the unlocked position and further includes a release mechanism to disengage the retention mechanism.

Abstract: An adaptor bracket for attaching a keyboard arm having a plate to a base frame wherein the adaptor bracket includes a housing having a projecting hook at one end and a projecting flange at the other end and the hook is adapted to fit over a slide member of the base frame and further wherein the adaptor is connectable to the slide member by engaging the hook with the slide member and attaching the flange to the slide member with a fastener.

Abstract: A lock for attaching a cover to a platform includes first and second pivotally mounted latch bars which spread to engage side walls of a strike opening in response to actuation of a key actuated rotatable plug mounted in the housing of the lock. The latch bars are mechanically spread to engage the strike in a positive manner and do not rely upon biasing means to maintain the lock in the locked position.
