A latch bolt mechanism for tilting window sashes includes an actuating spring that is integrally molded of plastic material in one piece with the latch bolt. The spring has a transversely corrugated configuration, comprised of at least two transversely disposed wave-like spring sections. Each spring section includes a pair of oppositely oriented U-shaped sections having spaced apart semi-cylindrical portions at opposite sides joined by transverse connecting sections. In a relaxed configuration of the spring, the several connecting sections are substantially parallel to each other and are longitudinally spaced apart. In a compressed configuration of the spring the connecting elements lie at an angle to each other and the several semi-cylindrical portions are closely spaced or in contact providing for the required spring compression without excessively stressing the plastic material. Significant production economies are realized with the one-piece, molded construction of the latch bolt and spring.

A fully functioning, pivoting vent stop for sliding windows has only two parts, a housing and a pivoting tumbler, both formed of injection molded plastic material. The tumbler is pivotally mounted in the housing and has integral detent elements cooperating with detent elements on the housing walls to position the tumbler in recessed or extended limit positions. The cooperating detent elements also provide an over-centering spring action as the tumbler is actuated between its limit positions. Assembly of the two-part device is achieved in a highly simplified and economical manner by configuring an internal cavity in the housing with inclined slots in the internal side walls of the housing. This enables the tumbler to be resiliently pressed into the cavity, temporarily displacing the housing side walls outwardly, until the cooperating pivot and detent elements are fully engaged.

A construction toy system comprised of a plurality of molded plastic girders and connectors. The girder elements of generally square cross section, with interlocking elements extending axially from each end. The interlocking elements each comprise a flange of square configuration, a groove structure of squared configuration adjacent the flange, and a generally cylindrical rod-like extension projecting between the end of the girder body and the groove structure. Connector elements are formed with one or more sockets for receiving interlocking elements of the girders. The sockets have one open side into which the interlocking elements can be inserted with a lateral snap-in action. The flange portions are freely received in a slot formed in the socket, and the groove structure engages and cooperates with opposed locking ribs formed on the sidewalls of the connector socket. Opposed axial grooves in the socket sidewalls engage opposite side portions of the rod-like extension with a snap-in locking action. At least certain of the girder elements include positioning and retaining elements for mounting of wall panels as part of an overall structure formed with girders and connectors. The above described elements are compatible with existing K'NEX construction toy sets utilizing rods instead of girders, enabling hybrid structures to be formed with combinations of girders and rods, for example.

Panel and girder system for construction toy

A panel for a multi-part construction toy characterized by having recesses along some or all of its side edges for the locking reception of connector elements of the type incorporated into standard K'NEX multi-part construction sets. The panels are designed for snap-in assembly of the connectors, enabling panels to be joined edge-to-edge to form a substantially continuous wall structure. With right angle connectors, panels can be joined edge-to-edge at right angles. The panels are also provided with central half slots, enabling two panels to be joined with each other in an X-shaped configuration.
