An apparatus for selectively adjusting the angle of inclination of a work surface, such as a desk top, comprising a casing attached to the bottom side of one end of the work surface, with a foot device comprising a circular cylindrical part with positioning channels in the periphery thereof and a foot member extending therefrom and with the cylindrical part contained within the casing, an engaging member projecting in the inside of the casing and for locking selected ones of the channels, and resilient member for holding the cylindrical part against the engaging member, whereby manual rotation of the foot member to different locking positions of the channels and engaging member, enables adjustment of the length and angle of extension of the foot member outside of the casing, and thus determine the space between the work surface and a base, with the other end of the work surface being pivotally connected.

An angle adjusting mechanism for use in selectively adjusting the angle of inclination of a work surface and disposed between said work surface and a base, said mechanism comprising a casing comprising a lower casing and an upper casing, with a pair of elliptical holes formed on opposite side walls

An angle adjusting mechanism for use in selectively adjusting the angle of inclination of a work surface and disposed between said work surface and a base, said mechanism comprising a casing comprising a lower casing and an upper casing, with a pair of elliptical holes formed on opposite side walls of said casing and in the area of the boundary between said upper casing and lower casing, said upper casing being attachable to said work surface and said lower casing being contactable with said base in a level position of said work surface; a foot device positioned within said casing and comprising a cylindrical portion having a plurality of channels in the periphery thereof, a pair of shafts extending from both ends of said cylindrical portion, and a foot member extending from said periphery of said cylindrical portion and having an end thereof contactable with said base in inclined positions of said work surface; an engaging member positioned within and attachable to said upper casing and above said cylindrical portion within contactable distance to said plurality of channels in said cylinder portion to determine the distance between the base and the work surface dependent on the particular one of said plurality of channels to which said engaging member is engaged, said distance determining said angle of inclination of said work surface; and resilient means for urging said cylindrical member against said engaging means, wherein said shafts are positioned within said elliptical holes to be rotatable and vertically movable therein so that in a level locked position of said work surface, said foot member is within the casing and said lower casing contacts said base, and the engaging member is engaged with one of said plurality of channels on the periphery of the cylindrical member, and so that in said inclined positions of said work surface the foot member is manually rotated outside of the casing and against the resilient force of said resilient means to disengage the engaging member from said one or other of said plurality of channels, until the cylindrical member presents another selected channel for engagement and said selected other channel is engaged by the engaging member with said foot member having said end portion thereof thereupon resting on said base at a selected distance from said work surface.
