Abstract
An adjustable table includes a base having an upright post with two vertical rows of openings therein. A tubular member is telescopically slidably supported on the post and has a downwardly facing bearing surface adjacent each row of openings in the post. A vertical lever is supported on the tubular member for pivotal movement about a horizontal axis, the pivotal support having a degree of vertical play, and has two locking members thereon each engageable with the openings in a respective row thereof and with a respective bearing surface on the lever. A table top is pivotally supported on the upper end of the tubular member for movement about a substantially horizontal axis and first locking means is fixably mounted on the tubular member. A leaf spring has one end fixedly secured to the undersurface of the table top and has second locking means thereon at a location spaced from the one end, the second locking means being movable between positions engaging and spaced from the first locking means by flexing the leaf spring. A selectively actuable disabling mechanism can render the leaf spring inoperative when the first and second locking means are engaged.
