Abstract: A lock release for folding tables and shelves in which the locking mechanism to prevent accidental pivoting of the top from a horizontal unfolded position to a generally vertical folded position includes a pivotal link member with guiding edges or surfaces for slidably directing a connector element along the link as the top is folded and unfolded. Most advantageously, the lock is double-acting--that is, two distinct manipulations are required to release the locking mechanism. In a preferred embodiment, the link member has an L-shaped guide slot with an elongated main portion and a relatively short end portion. When the top is horizontal, the connector element is located within the slot's end portion and, to permit the connector element to enter the elongated main portion of the slot, the link member must be shifted about its pivotal axis by the user.

Abstract: An infant bathing bassinet with a wheeled tub support and a wheeled supply cabinet that nests with this tub support from a frontal direction. A coupler temporarily joins the tub support and supply cabinet so they can be wheeled about as a unit. The supply cabinet has a pair of openable front doors which can widely swing open through an angle of approximately 270.degree. without interferring with the tub support structure.

Abstract: A pole attached to a hospital stretcher or the like for supporting an intravenous solution container. This pole has an improved collapsible construction attaching it to the stretcher so such pole does not interfere with any stretcher operation.
