Patent ID: 7946012

Claim:
A waste disposal sink mount installation system, the installation system for temporarily fixing a flanged drain collar, the temporarily fixed drain collar for enhancing manual installation of a mount-retaining snap ring fastener thereupon, the installation system comprising, in combination: a system-supporting sink basin, the sink basin comprising a drain aperture; a flanged drain collar, the drain collar being receiveable in the drain aperture and comprising an outwardly extending sink-engaging flange, an inwardly extending cap-engaging flange, and a ring-receiving recess intermediate the sink and cap-engaging flanges, the sink-engaging flange for supporting the drain collar at the sink basin; a spring-actuable snap ring fastener, the snap ring fastener being actuably receivable in the ring-receiving recess; a ring-cap assembly, the ring-cap assembly being receivable in the flanged drain collar and comprising a drain-sealing cap and a hook ring, the cap-engaging flange for supporting the ring-cap assembly in the flanged drain collar; a waste disposal upper mounting assembly, the upper mounting assembly comprising a mounting ring, and a plurality of fasteners, the fasteners being attachable to the mounting ring and downwardly extendable in parallel relation to one another; and an installation apparatus, the installation apparatus comprising a guide rail and a carriage assembly, the guide-rail and comprising a hooked end and a notched face, the carriage assembly comprising a centralized rail guide aperture, a plurality of fastener-engaging arm assemblies, and a spring-actuable notch stop, the guide aperture receiving the guide rail, the spring-actuable notch stop being engageable with the notched face for enabling a user to selectively prevent carriage translation relative to the guide rail, the arm assemblies comprising a plurality of parallel fastener-receiving ports, the upper mounting assembly being receivable about the guide rail, the fasteners being receivable in the fastener-receiving ports, the hooked end being hookable upon the hook ring, the carriage assembly being translatable toward the flanged drain collar along the guide rail, the upper mounting assembly thereby being positionable intermediate the sink-engaging flange and the ring-receiving recess, the spring-actuable notch stop for locking the carriage assembly upon the guide rail with the upper mounting assembly fixedly positioned intermediate the sink-engaging flange and the ring-receiving recess and for temporarily fixing the flanged drain collar, the installation apparatus thus for enhancing an installer's ability to manually install the snap ring fastener upon the flanged drain collar, the snap ring fastener, thus installed, for preventing downward displacement of the mounting assembly relative to the flanged drain collar, the mounting assembly, thus positioned, for enabling proper waste disposal unit mounting.
