Drain installation apparatus

A drain installation apparatus for installing a drain assembly in a drain hole of a plumbing fixture, said apparatus comprising:

• an upper holding-assembly for positioning above and bridging over the drain hole in the plumbing fixture, said upper holding assembly comprising:
• a bridging member for bridging over the drain hole, said bridging member having a central portion and a pair of end portions, a hole being formed in said central portion of said bridging member, said bridging member having a substantially U-shaped configuration with said end portions extending away from said central portion in a substantially parallel orientation to each other, a central axis of said hole being substantially parallel to each of said end portions;
• a support member for extending toward the drain hole when said bridging member is positioned over the drain hole, said support member being selectively advanceable toward the drain hole, said support member being positioned in said hole in said bridging member, an exterior of a portion of said support member and an interior of said hole in said bridging member being threaded such that rotation of said support member advances said support member through said hole in said bridging member, said support member having a first end and a second end;
• a holding member for engaging a top of the drain assembly, said holding member being rotatably mounted on said first end of said support member;
• a handle member being mounted on said support member for being gripped by a hand of a user to rotate said support member, said handle member being mounted on said second end of said support member;
• and
• an attachment member being mounted on said bridging member for releasably mounting on an inner surface of the plumbing fixture adjacent to the drain hole, one said attachment member being mounted on each of said end portions of said bridging member;
• a lower holding assembly for positioning under the drain assembly below the drain hole in the plumbing fixture, said lower holding assembly comprising:
• a cup member for engaging an upper portion of the drain assembly, said cup member defining a cavity for receiving the drain assembly, said cup member having a central wall and a peripheral wall extending from said central wall, said peripheral wall having an edge defining an opening into said cavity, a plurality of notches being formed in said edge, said notches being substantially uniformly separated along said edge and a circumference of said opening such that said notches coincide with an upper fastener, wherein said cup member is positionable over the upper portion of the drain assembly until said notches fully receive the upper fastener to facilitate securing the upper fastener to a first threaded portion of the drain assembly.
• a lower handle member mounted on said cup member for gripping by the hand of the user to produce rotation of said cup member, said lower handle including a post member extending from said cup member and a cross member mounted on said post member, said cross member being mounted on said post member in a manner such that said cross member is oriented substantially perpendicular to said post member, said post member being mounted on said central wall of said cup member;
• an engaging member for engaging a lower portion of the drain assembly, said engaging member being removably mountable on said cup member, said engaging member having an inner perimeter edge defining an aperture, a shape of said aperture being generally the same as a shape of a lower fastener, said engaging member having an outer diameter generally equal to an inner diameter of said opening in said cup member such that said engaging member is positionable in said cup member, a pair of tabs extending radially outward from said engaging member for engaging a number of said notches in said cup member, said pair of tabs extending from diametrically opposite locations on said engaging member, wherein said engaging member is positionable over the lower portion of the drain assembly until said aperture fully receives the lower fastener to facilitate securing the lower fastener to a second threaded portion of the drain assembly.
