Abstract: A plastic lift arm for toilet flushers having enhanced-function flush handles—such as a Flush Handle Night Light carrying a standard, 9-volt battery—that exerts a torque sufficient to maintain an enhanced-function flush handle in a generally horizontal position when not in use. The plastic lift arm completely encapsulates a steel or iron counterweight and thus eliminates the need to plate the metal to prevent rusting in a moist environment. In order to maximize leverage, the counter-weight is located close to the conventional series of holes for chain clips. The counterweight has a diameter as large as possible consistent with the need to preserve moldable wall thickness. The lift arm may be bent or shortened to conform to almost any existing installation without compromising its ability to maintain the enhanced-function flush handle in a horizontal, at-rest position.

Abstract: An integrally formed means for connecting plastic parts that exploits persistent, resilient deformation through studs that are pressed in and through double-tapered holes wherein a neck smaller in cross section than the corresponding studs has been formed. By varying the relative cross sections of neck and stud connection strength may be adjusted. By providing studs shorter than the double-tapered hole, cavities become available for chemically converting the reversible, frictional cum interference connections into permanent connections. By adjusting the height 11 of the neck relative to the length of the corresponding studs, parts may be kept in registry and their assembly thus eased. Parts having side walls of sufficient height, although connected in principal reversibly, in practical effect become irreversibly connected. Such connective means may reduce the need for ultra-sonic welding, reliably reported to disturb electrical circuitry mounted on parts to be connected.

Abstract: A toilet flusher in which the plastic lift arm normally hidden from view inside a toilet tank comprises a bi-concave segment readily bent by hand, allowing the toilet flusher to integrate well with a wide variety of flush mechanisms already found installed inside toilet tanks. Bending forces are concentrated along a line rather than at a point, so that the inadvertent cracking of the lift arm during on-site modification that sometimes occurs in lift arms having cruciform cross sections is much less likely to occur.

Abstract: A toilet flusher comprising an exterior flush handle and a means for limiting the flush handle's rotation, the means being located entirely within the toilet tank. The means involve both the rear planar as well as the side cylindrical walls of the spud, in order to enhance the spud's strength and rigidity. The means further comprise a bent lift arm within the tank, and a motion limitation hub on the lift arm. The hub is sufficiently distant from the bend of the lift arm that conventional attachment of the toilet flusher to the front wall of a toilet tank, by passing the conventional left-handed nut over the entire visible length of the lift arm, including over the motion limitation hub, and onto the threads of the spud, may be easily accomplished. This is particularly advantageous for enhanced-function flush handles that are designed to be connected removably to the remainder of the toilet flusher and that will thus typically lack space within their housings to accommodate the usual, motion limitation means.

Abstract: A means for attaching a toilet flush actuator to a toilet that allows for quick, easy removal of the actuator from the toilet without the use or a tool or tools. Simultaneously, the means of attachment prevents the actuator from inadvertently slipping off the toilet during everyday use, over many months and years. The means of attachment permits such possible contents of the actuator as, for example, a battery or an air freshener pack, to be changed and/or serviced readily, and further permits the toilet to be flushed even though the actuator itself has been removed.
