Abstract

An on-site reglazable window assembly suitable for mounting in an aperture in a wall of a recreational vehicle and comprising a stationary glass panel, a slidable glass panel, a slidable screen panel, and slidable storm panels. All of the panels are removably positioned within a generally rectangular frame formed of a unitary metal extrusion having a plurality of flanges which provide glazing channels for the panels and means for mounting the frame to the vehicle wall. One of the exterior flanges includes a key-shaped slot which receives a correspondingly keyed flexible gasket along the entire perimeter of the frame. The gasket has a plurality of splines attached to a compressible tube so that the splines and tube are compressed between the inner surface of the exterior flange and the outer surface of the vehicle wall. The slidable screen and storm panels slide within respective channels of a removable multiple channel track. The relative position of the stationary and slidable glass panels permits employment of a centrally located latch assembly. The frame employs a sloped base to permit drainage of rain water and the like through at least one slot or weep hole in the bottom edge of the window assembly. A removable track used for the slidable glass panel employs widely separated support legs disposed to rest upon track ledges which lie within an intermediate glazing channel but displaced above the base surface to preclude obstruction of the draining water by the track support legs. In one form of the invention, the frame is hingedly connected to the motor home wall and may be rotatably swung out about hinges.

An improved window assembly adapted for installation in an aperture of a recreational vehicle wall structure and comprising:

a. a metal frame having a base and a plurality of approximately parallel inwardly extending flanges integral with and transverse to said base and surrounding said frame to form a plurality of channels therein of which the base provides a common floor, said frame also having an outwardly facing circumferential flange for surrounding said aperture and for lapping the outer surface of said wall structure adjacent said aperture, said floor being sloped with respect to a plane perpendicular to said wall structure, at least one of said channels having opposed ledges elevated above the floor of said channel and being adapted to support a flexible track member elevated above said floor, at least the two outermost flanges being slotted along a common axis adjacent said base to provide aligned drainage apertures through which any water in said one of said channels drains along said sloped floor to the exterior of said wall structure;
b. a stationary removable glass panel positioned in the outermost one of said channels, a slidable removable glass panel positioned in an inner one of said channels for sliding therein;
c. securing means positioned at the approximate center of said window assembly, said securing means comprising a latch member attached to a vertical edge of said slidable window panel and a catch member attached to a corresponding vertical edge of said stationary window panel whereby said latch member and said catch member may be securely interlocked for securing said window assembly in a closed configuration;
and
d. a flexible track member having a channel therein for slidably receiving one of said panels, said flexible track member being positioned in the said one of said channels having opposed ledges, said flexible track member having two separate legs, each such leg being positioned on a channel ledge whereby said track member is elevated above said channel floor to permit unobstructed drainage along the floor and through said aligned drainage apertures.
