Abstract

A securing mechanism for use with a recreational vehicle (RV) slide out assembly. The securing mechanism structurally interconnects the slide out assembly to the RV when the slide out assembly is in a retracted position and when it is in an extended position. Specifically, loads in the RV induced from the road, from passengers, from equipment, and other various sources are distributed through the slide out assembly. Advantageously, flexure of the RV walls around the slide out opening is reduced. As a result, walls and their fixtures are less likely to be damaged due to flexure, seals between the RV walls and the slide out are more likely to stay intact, and the size of slide outs can be increased without compromising the structural integrity of the RV.

Claims

1. A recreational vehicle comprising:

a main housing having a plurality of walls that are joined together so as to define an interior living space, wherein the plurality of walls includes a first wall having an opening formed therein so as to define upper and lower portions of the first wall;

a slide-out housing positioned in the opening in the first wall so as to be movable between a retracted position and an extended position, the slide-out housing having an outer plate that is positioned adjacent the upper portion of the first wall when the slide-out is in the retracted position and an inner plate that is positioned adjacent the upper portion of the first wall when the slide-out is in the extended position;

a securing mechanism having one or more first securing components positioned adjacent the upper portion of the first wall and a plurality of second securing components positioned adjacent the outer and inner plates of the slide-out housing, wherein the plurality of second securing components engage with the one or more first securing components when the slide-out housing is in the retracted position and the extended position thereby allowing forces on the first side wall to be transferred to the slide-out housing to reduce deformation of the first side wall when the slide-out housing is in the retracted position and the extended position; and

wherein the slide-out further includes a lower outer plate that is positioned adjacent the lower portion of the first wall when the slide-out is in the retracted position, and wherein the securing mechanism further comprises one or more third securing components positioned adjacent the lower portion of the first wall and one or more fourth securing components positioned adjacent the lower outer plate of the slide-out housing, such that engagement of the one or more third securing components with the one or more fourth securing components provides additional support against deformation of the first side wall when the slide-out is in the retracted position.

2. The recreational vehicle of claim 1, wherein a given one of the one or more first securing components engages a corresponding second securing component positioned adjacent the outer plate when the slide-out is in the retracted position and a corresponding second securing component positioned adjacent the inner plate when the slide-out is in the extended position.

3. The recreational vehicle of claim 2, wherein each of the one or more first securing components comprises an elongated slot having horizontal and vertical dimensions, and each of the plurality of second securing components comprising a cylindrically shaped post, wherein the horizontal dimension of the elongated slot is selected so as to receive and restrict horizontal movement of the cylindrical shaped post, and wherein the vertical dimension of the elongated slot is greater than the horizontal dimension.

4. The recreational vehicle of claim 1, wherein one of the one or more first securing components and corresponding second securing components positioned proximate a midpoint of the slide-out housing along a longitudinal direction that is generally perpendicular to the lateral direction along which the slide-out moves between its retracted and extended positions.

5. The recreational vehicle of claim 1 wherein each of the one or more third securing components comprises an aperture, and each of the one or more fourth securing components comprises a cylindrically shaped post, wherein the aperture is dimensioned to receive the cylindrical shaped post.
