Abstract: A mobile home includes two hingedly connected habitable parts each comprising a room-like enclosure mounted on a rectangular perimeter frame. Two braced posts are provided on adjacent end corners of each frame with corresponding posts of the two frames side by side when the parts of the mobile home are aligned end to end. Hinges connect adjacent first posts of the two frames and releasable catches connect the other posts of the two frames thereby allowing the habitable parts to maintain an end to end relationship for towing and alternative side by side relationship for living quarters. Door openings in the habitable parts allow person communication between the habitable areas within the enclosures when the parts are side by side. Wheels are provided on one perimeter frame along with a towing device on an end of the other perimeter frame opposite to that having the posts.

Abstract: A roller shutter door comprised of a plurality of horizontal panels with interengaged curled longitudinal edges to provide hinge action between the panels. There are strips of resilient material under a compressive load in the hinge joints to substantially eliminate slackness in the hinge joints. The invention also provides a method of assembling such doors, the method involving inserting a strip of resilient material in the curl of a first panel and applying a longitudinal load to the material to cause it to adopt a reduced cross-sectional size followed by the longitudinal insertion of the curl of a second panel into the curl having the stressed material therein and then releasing the load on the material to allow it to urge the curls of the interengaged panels into firm contact one with the other.
