Abstract: An improved brake and tilt 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 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 releases the locating mechanism and permits adjustment of the tilt or attitude of the keyboard platform relative to the linkage arms.

Abstract: A counterbalance table includes telescoping members for supporting the table. The telescoping members are augmented by gas cylinders which may be locked to preclude engagement with the table or unlocked so as to engage the table and facilitate supporting the table and a load thereon.

Abstract: A cushion and stop detent member for a drawer slide includes cushioning arms, a detent projection and a frictional ramp or surface all embodied in a single element positioned to engage telescopic slide members of a drawer slide construction in a manner which cushions the movement of the slide members to the closed position, reduces any rebound, and provides a detent closure retention of the slide in the closed position.

Abstract: Anti-rebound drawer slide includes a leaf spring positioned at the inner end of the slide cooperative with a cam that receives an inner slide channel. Rotation of the cam by engagement with the slide channel is controlled and an anti-rebound effect is achieved by virtue of the engagement of the leaf spring with the cam.

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 releases the locking mechanism and permits adjustment of the tilt or attitude of the keyboard platform relative to the linkage arms.

Abstract: A storage and security case for a personal computer comprises a housing with fold over side platforms which 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: There is disclosed an adjustable tilt mechanism for a keyboard support platform. The keyboard support platform is of the type that includes a linkage for connecting the platform to a work surface. The linkage further includes connecting arms which pivotally connect the keyboard support platform to the work surface. The adjustable tilt mechanism of the present invention includes a tilt adjustment member that is movable transversely relative to the pivot axis of the platform. Engaging the tilt adjustment member is an angled shaft which is fixed to the platform between the sides of the platform. The tilt adjustment member is also pivotal about a second fixed shaft that is parallel to the pivot axis of the platform. A releasable latching member is mounted on the connecting arms for engaging and releasing the tilt adjustment member.

Abstract: An improved padlock assembly is provided which includes a lock body, a shackle with a pair of opposed legs fitting into the lock body, and the lock body including an interior chamber in which are positioned a pair of reciprocal lock plates. A first lock plate operates in response to the manipulation of the lock cylinder, while the second lock plate operates in response to a lock pin to keep it in a locked and/or unlocked position. The entire shackle may be removed by first removing the first shackle leg from locking engagement with the first lock plate, moving the first lock plate back to its locked position, afterwhich the lock pin may then be removed to move the second lock plate to its unlocked position in order to free the second leg of the shackle and thereby remove the entire shackle.

Abstract: A pin tumbler mechanical lock includes an electronic component incorporated in the key which connects to an axial lead aligned to mechanically engage the spring biased contact of the key whereby in order to operate the lock both the mechanical pin tumblers and the electronic signal provided by the key are necessary.

Abstract: An axial pin tumbler lock and key assembly comprise a housing with an axial pin tumbler barrel fixed within the housing and including passages for storage of key change tumblers. A rotatable forward barrel and spindle include axial pin tumblers movable in response to the insertion of an appropriate key of the type having a hollow cylindrical barrel for engagement with the tumblers. The key includes detents on the inside surface of the cylindrical barrel and radial ribs on the outside surface thereof for actuation of the front barrel.

Abstract: A removable core, axial pin tumbler lock includes an inner cylinder assembly which is retained within a housing for the lock by means of a spring biased disc which may be decoupled from the housing by means of insertion of a pick through a passageway defined in the inner cylinder assembly when the components parts of the assembly are appropriately aligned.
