Abstract: A convertible peripheral input device comprises a control pad and a multiaxis input device selectably mounted on the edges of the control pad so that the multiaxis input device can be positioned for right-handed use or left-handed use according to the user's preference. The multiaxis input device can be rotated from one position to another by the use of a hinge mechanism with two points of rotation: one for rotation of the multiaxis input device 180 degrees relative to the hinge mechanism and the second point of rotation allowing the hinge mechanism to be rotated 180 degrees relative to the control pad bottom surface. The rotatable hinge mechanism may be used with videogame control pads and joysticks as well as keyboards with mouse controllers.

Abstract: A stack of interfitting sieve trays are held in position on a carrier by an upstanding periperial wall on the carrier which engages the lower portion of the lower sieve tray, and by a plurality of clamp-down units which at their lower ends are pivotally connected to end portions of the carrier and at their upper ends include a lever operated hook mechanisms for engaging upper edge portions of the top sieve tray. Side edge portions of the carrier are provided with upper and lower bearing strips. These edge portions are received between upper and lower sets of cam rollers which are mounted onto web portions of side members which have been fashioned from channel stock. The side members carry bearing strips which contact and guide the side edges of the carrier. The clamp-down units are overweighted on their outer sides so that when released they will fall outwardly against stop means for limiting the amount of outward movement.
