Convertible vehicle topwell drainage arrangement
First Claim
1. A topwell assembly drainage arrangement for an automotive vehicle body comprising:
- a molded, rigid shell-like topwell assembly for attachment to the vehicle body and made of plastic material molded to conform to an environment of continuous and non-continuous surfaces, comprising a support floor together with side, front and rear walls projecting upwardly from said floor, said floor having a water discharge recess adapted to receive run-off water drainage;
said recess having a frusto-conical shaped side wall defining an upper large diameter inlet opening in the surface of said floor and terminating in a lower small diameter base wall, said base wall having a concentric central outlet hole therein aligned on a principal axis of symmetry of said recess;
a plurality of fasteners for fixedly installing said topwell assembly floor a predetermined dimension above a subjacent horizontally disposed body support panel having an aperture therein;
a water discharge one-piece fitting mounted in said support panel aperture prior to said topwell assembly being installed thereabove, whereby upon said assembly being installed the center of said support panel aperture is aligned on said recess principal axis;
said fitting having an annular body side wall defining an upper large diameter opening and terminating in a lower bottom wall, a collar extending radially outwardly from said upper opening and said bottom wall formed with a downwardly extending spout defining an axial passageway for water exiting said recess; and
said collar having side edges formed with oppositely facing downwardly projecting tabs adapted for snap-in reception in said support panel aperture.

Abstract
A split-installation drainage arrangement for a convertible vehicle topwell assembly adapted for storage of the top in a downwardly folded position. The plastic shell-like topwell includes a floor molded with right and left side water collecting areas each terminating in a drainage recess. A sub-assembly, adapted for transporting water from an associated recess to the exterior of the vehicle, includes a one-piece discharge fitting and a sealing grommet interconnected by a flexible drain tube. The tube has one end attached to an exit spout of the fitting and its other end adapted for insertion in a body panel aperture by means of a snap-in sealing grommet. The sub-assemblies are readily installed in the vehicle body prior to the installation of the topwell. Each fitting has a collar adapted for snap-in mounting in a body support panel oval-shaped aperture. As a result, the frusto-conical shaped drainage recess exterior male taper surface is located in self-aligned spaced relationship with the interior female taper surface of the subjacent frusto-conical shaped fitting obviating assembly line inter-connections between the floor recess and the support panel fitting.

10. A one-piece discharge fitting adapted for snap-in attachment in an oval-shaped aperture of a body support panel, wherein the aperture defined by a pair of opposed parallel side edges and a pair of opposed half-round end edges having a predetermined radius of curvature, said discharge fitting comprising:
-
a frusto-conical shaped side wall portion defining an upper large diameter opening and terminating in a lower small diameter bottom wall defining a funnel-shaped cup; a rectangular-shaped collar extending outwardly from said upper opening and said bottom wall formed with a downwardly extending spout defining an axial passageway for water exiting said spout; said collar having side and end edges, said end edges being formed with oppositely facing downwardly projecting tabs symmetrically aligned on a major center line axis of said collar; each said tab having an outer face formed with a downwardly and outwardly sloped locking shoulder terminating in an outwardly bowed lead-in self centering cam portion having a radius of curvature substantially equal to but slightly greater than said predetermined aperture half-round end edge border radius of curvature, and whereby the support panel having an upper surface flush with an opposed undersurface of said collar and wherein each said tab locking shoulder adapted to underlie a portion of the support panel. - View Dependent Claims (11)
