A combination serving tray, bed tray and bathtub tray. A “U-shaped”leg is hinged at each end of an elongated tray, to swing from a closed position underneath the tray frame down into a generally upright position. In this position, the legs hold the tray a predetermined height above the surface on which the legs are supported. A cammed latch is provided beneath the bottom surface of the tray, positioned to engage the resiliently bendable bight portion of each “U”-shaped leg when the leg is swung up from its open position to its closed position. Handles are provided at each end of the tray, slidably engaged with the tray frame and movable outward a predetermined maximum distance but no farther. In its preferred form, the cammed latch includes a spherical body that engages the resiliently bendable bight portions of the “U”-shaped legs to hold them in their closed positions.

In a combination serving tray, bed tray and bathtub tray, the subcombination which comprises: (a) an elongated tray frame providing a support surface for objects to be placed on the tray; (b) a “U”-shaped leg hinged at each end of the tray to swing from a closed position located underneath the tray frame, in which position the leg is substantially parallel to the bottom surface of the tray, downward into a vertical position and then beyond into an over-center, open position, in which position the leg is generally upright, said “U”-shaped leg having a bight portion that is normally stiff but is resiliently bendable under pressure; (c) stop means for each of said “U”-shaped legs, said stop means being configured to limit the leg from moving beyond said over-center, open, generally upright position, in which position the two “U”-shaped legs hold the tray at a predetermined height above the surface on which the legs are supported; and (d) latch means located on the underside of the tray, said latch means including a camming surface associated with each of said “U”-shaped legs, each of said camming surfaces facing an end of the tray in a position to engage the bight portion of its associated “U”-shaped leg when the leg is swung up from its open position to its closed position, said camming surface being configured to bend said resiliently bendable bight portion of the leg as the bight portion (i) is pushed toward the bottom of the tray by the user of the tray, (ii) slides across said camming surface, and (iii) after riding over the camming surface, snaps back to its normal shape to hold the leg in its closed position beneath the tray.
