Abstract: In a dimensionally precise electronic component mount, electrical terminals are affixed with dimensional precision to a rigid insulative base. An electronic component is affixed in precisely indexed abutment to the rigid insulative base. A protruding wire of the electronic component is conductively affixed within a v-shaped notch adjacent a notch apex in a second electrical terminal. Embodiments of the rigid insulated base include a flat rectangular plate and a hollow tube having a rectangular cross-section. Contact surfaces and contact pins coact respectively with hybrid substrates and printed circuit boards. Web means coupling adjacent iterated embodiments supports and provides dimensional precision during assembly. An embodiment having a plurality of electrical terminals permits accommodation of an electronic component having a plurality of protruding wires. Mechanical affixation is accomplished alternatively by soldering, welding or adhesives.

Abstract: An improved lock strike plate and security chain means are rotatably coupled within a recess within the strike plate means as well as within a recess of the door frame to which the strike plate is mounted. Means are provided within the security chain latching means to inhibit the decoupling of a security chain latched thereto when the door is placed ajar. Further means are provided for exterior key actuation of the chain latch to permit decoupling of the latch from a security chain by a person outside the secured area in an emergency situation. Orthogonal coupling means matingly engaged within the interior of the door frame itself strengthen the strike plate/chain latch assembly, reinforcing the door frame and making that frame a more integral part of the door locking assembly than has been heretofore achieved in the prior art.

Abstract: A door stile lock has a rotary latch bar. The rotary latch bar contains a compression loaded anvil within its interior. The latch bar rotates about the lock cylinder housing. The housing is provided with retention ports for engaging the compression loaded anvil at selected positions to inhibit rotation of the latch bar when the anvil is so engaged. Interior of the cylinder housing is an actuator rotatable by the lock key. The actuator raises the anvil from the retention ports and drives the latch bar about the axis of the cylinder housing between nominal locked and unlocked positions of the latch bar. The compression loaded anvil engages the retention ports in the cylinder housing at both the nominal locked and unlocked positions. A lock body engages the cylinder housing in a non-rotating manner. The lock body is then compressively engaged within the door stile.

Abstract: A deadbolt lock is adaptable for installation in doors of various thicknesses. The lock body and interior rosette are established at a fixed position with respect to the interior surface of the door in which the lock is mounted. A cylindrical threaded coupler is threaded to an extension of the exterior keyway-carrying rosette of the lock and the coupling between the threaded cylinder and the threaded extension of the rosette are adjusted in accordance with the thickness of the door to which the lock is installed. The interior threaded coupling cylinder is then inserted within the bore of the lock, the mounting being achieved without interference with the deadbolt throw/retract mechanism interior of the lock body.

Abstract: A lock body having compressive engagement with the interior of a hollow structural member of a door, such as a hollow stile. A compressive element is coupled to the lock body by means of a screw fastener. The compressive element has limited rotation about the axis of the screw fastener; the friction of the threaded coupling between the screw fastener and the compression element causing the compression element to rotate about the axis of the screw fastener. Such rotation is limited to approximately 90.degree. by an abutment stop provided on the body of the lock. When the compression element is drawn into abutting contact with the stopping abutment, continued actuation of the screw fastener causes the compression element to traverse the axis of the screw fastener.

Abstract: In aid of a person transporting a narrow oblong object traversing obstacles of various heights, the object is supported at one end by a single wheel disposed adjacent the dihedral intersection of a narrow end and a narrow longitudinal side, the rotational plane of the wheel coinciding with a plane of weight symmetry of the narrow oblong object to reduce tipping tendency when support and propulsion is provided by the person manually at an end opposite the wheeled end. Various means are disclosed for coupling the single wheel to the narrow oblong object, including concave socket and clamp means. Adjustment is provided for coinciding wheel rotational plane with the plane of weight symmetry.

Abstract: A protruding lever is releasably attached to a conventional flush-tank pivoted flush handle, extending toward a locus of the user's convenient arm flexure. The user is thereby enabled to actuate the flush lever without contortion from conventional seated position. The invention swings away from the user when inadvertently contacted, while retaining rigidity in the direction of flush actuation. An elbow-conformal recess facilitates confortable actuation by the user's elbow. The invention is releasably clamped to and wholly supported by the conventional flush handle.
