Abstract: An active interlocking fastener system is adapted to control an interlock in response to an external stimulus. The interlocking fastener system includes a first element including a plurality of first interlocking fasteners. The interlocking fastener system also includes a second element including a plurality of second interlocking fasteners configured to couple to the first plurality of interlocking fasteners. The plurality of first interlocking fasteners or the plurality of second interlocking fasteners includes a reactive material configured to vary a mechanical engagement between the plurality of first interlocking fasteners and the plurality of second interlocking fasteners as a function of the external stimulus.
Abstract: A recreational vehicle (RV) includes a slide-out compartment that increases a size of an interior living space. The slide-out compartment extends from and retracts into a rear side of the RV. The slide-out compartment includes a plurality of panels coupled to a rear double door structure. The plurality of panels configured to extend from the RV in an open state and recede into the RV in a closed state. The double door structure is configured to recess into a rear door jamb of the RV and form a weather seal with the rear door jamb when the slide-out compartment is in a closed state and detach from the door jamb when the when the slide-out compartment is not in a closed state.
