Abstract

A modular molding system is provided for mounting at a wall-ceiling interface in a structure, such as an RV, and around a window opening in the structure. The system includes a mounting component and a trim component removable mountable to the mounting component. The mounting component is configured in one embodiment to be mounted to the wall-ceiling interface and in another embodiment to be mounted around a window opening. The molding system includes a functional component separate from the function of the molding system. In one embodiment, the functional component is an LED lighting strip and, in another embodiment, the functional component is a guide channel for a screen or sunshade of a window valence. A snap-fit engagement is provided between the mounting component and the trim component. The mounting component and the trim component are extruded plastic so that that the components can be cut to size as desired.

Claims (22)

1 . A modular molding system for providing an aesthetic feature to a wall and/or ceiling structure, comprising:

a mounting component including;

an elongated base track configured to be seated at the interface between a vertical wall surface and a ceiling surface, and including a vertical fastener panel configured to engage said vertical wall surface and a horizontal fastener panel configured to engage said ceiling surface; and

at least one functional component providing a function different from the aesthetic feature of the molding system;

a trim component including an elongated trim panel sized to conceal the mounting component when the trim panel is engaged to the mounting component and the mounting component is fastened to the wall and/or ceiling surface, wherein the trim component has a width along the elongated trim panel and includes an end panel at each opposite edge of said width, each end panel extending inward and generally perpendicular from said trim panel; and

a removable snap-fit connection between the base track and the trim panel, wherein the removable snap-fit connection includes:

a pair of retention arms defined by the base track and projecting outward from said fastener panel;

a first pair of resilient prongs projecting from an inner surface of the trim panel, said first pair of resilient prongs configured to be deflected relative to each other upon selective snap-fit engagement with the pair of retention arms, thereby exerting a spring force to hold the prongs in engagement with the retention arms; and

a second pair of resilient prongs projecting from said inner surface of the trim panel and spaced apart from said first pair of resilient prongs, said second pair of resilient prongs configured to be deflected relative to each other upon selective snap-fit engagement with the pair of retention arms, thereby exerting a spring force to hold the prongs in engagement with the retention arms,

wherein said first pair of resilient prongs is arranged so that the end panel at a first one of said opposite edges is in contact with said vertical wall surface when the first pair of resilient prongs are engaged with the pair of retention arms, and the end panel at a second one of said opposite edges is spaced apart from said ceiling surface to define a first gap; and

wherein said second pair of resilient prongs is arranged so that the end panel at a second one of said opposite edges is in contact with said ceiling surface when the second pair of resilient prongs are engaged with the pair of retention arms, and the end panel at said first one of said opposite edges is spaced apart from said vertical wall surface to define a second gap.

2 . The modular molding system of claim 1 , wherein:

the base track defines at least two mounting surfaces separate from the fastener surface, a first one of said mounting surfaces arranged to align with said first gap, and a second one of said mounting surfaces arranged to align with said second gap; and

the functional component includes an LED lighting strip configured to be mounted on any of said at least two mounting surfaces, said LED lighting strip configured to generate light to pass through one of said first gap and said second gap depending on the arrangement of the trim component on the mounting component.

3 . The modular molding system of claim 1 , wherein:

the base track defines a mounting surface separate from the fastener surface; and

the functional component includes an LED lighting strip configured to be mounted on said mounting surface.

4 . The modular molding system of claim 3 , wherein said base track defines a wiring channel for receiving wiring associated with said LED lighting strip.

5 . The modular molding system of claim 4 , wherein:

said elongated base track defines an elongated fastener channel extending from each of said vertical and horizontal fastener panels, each elongated fastener channel configured to guide an elongated fastener to the corresponding fastener panel; and

said fastener channels and said fastener panels defining said wiring channel.

6 . The modular molding system of claim 1 , wherein said elongated base track defines an elongated fastener channel extending from each of said vertical and horizontal fastener panels, said elongated fastener channel configured to guide an elongated fastener to the corresponding fastener panel.
