Abstract: A multi-directional mounting bracket for adjustably mounting an object to a structure, such as a loudspeaker is disclosed. The mounting bracket incorporates a ball and socket mounting arrangement. Locking means including an array of indentations is provided, wherein the indentations define a plurality of predetermined positions.

Abstract: An interlock structure of the cable type for stacked plural drawer cabinet structures which limits the opening of drawers to a single drawer and prevents plural drawers being opened at the same time. An elongate base or frame is mounted in the cabinet adjacent to the drawers. The frame supports plural (one for each drawer) eccentric blocker elements and adjacent follower elements and supports at one end a provided slider element having limited movement. A cable is attached at one end to the slider and at the other end to the frame with an intermediate loop which provide two cable courses, one of said courses threaded on the successive blockers and the other course operably threaded over the respective adjacent followers maintaining the respective blockers and followers in operative engagement. The blockers are moved by interference engagement by a selected drawer.

Abstract: A spring biased hinge for refrigerator doors and the like includes a stationary mounting bracket, a bent-wire spring mounted between the door and bracket, and a pivot pin for pivotally mounting the door to the mounting bracket. The mounting bracket is reversible so that it can be used on either side of the door, and includes a slot for receiving an end of the spring, the slot and spring being located so that as the door is opened, the door travels through a first arcuate segment where the spring is compressed and oriented to bias the door closed, through a second arcuate segment where the spring is compressed and oriented to bias the door open, and a third arcuate segment where the spring is not compressed but rather slides in the slot allowing the door to swing freely open until an end of the slot is engaged to limit the maximum door open movement. The hinge is characterized by its low profile and low number of parts.

Abstract: A drawer interlock structure having a channel-like plural station frame supporting at each station a cam on one side of the frame and an operably connected slider movable by the cam on the other side of the frame. A trip pin is attached to each drawer and is located in the opening and closing of each drawer to operably engage the cam. As the cam moves and the slider is displaced a taut strap of flexible material is displaced against a spring force at opening of any one drawer and the spring is limited in its extension by a blocker whereby no other drawers can be opened until closure of the one opened drawer and whereby simultaneous movement of plural drawers are blocked by the limitedly blocked spring loaded strap. The withdrawal of the slider from a positive block against the cam is prevented until the single opened drawer is closed. Simple locking of the structure is by means of a lock device disabling any movement of the strap.
