Abstract: A cigarette holder for assisting a smoker in stopping smoking has an outer tube whose rear end is provided with a mouthpiece and whose front end is provided with a metal snuffing collar. Inside this other tube is another tube that acts as a stop for a cigarette inserted into the outer tube, and that is provided with break formations such as grooves or notches so that it can be shortened. This inner tube is therefore periodically shortened so that the amount of cigarette that can be inserted or received within the holder and in back of the snuffing collar increases. Thus the amount of each cigarette that can be smoked with the holder can be decreased step-wise to allow the user to reduce the amount of each cigarette smoked. Ultimately cigarette smoking can thus be stopped.

Abstract: A vehicle whose interior is accessible from the outside through openable doors is provided with an enclosure extension formed with a support fixed on the vehicle in the vicinity of and generally above the aperture formed by the doors and generally within the vertical projection of the vehicle. A full-suspension frame is displaceable on the support between a retracted position generally within the support and an extended position extending from the support and from the vehicle above the aperture. A pair of side walls formed as hinged-together panels, a top wall, and a bottom wall are carried on the frame and displaceable therewith.

Abstract: A mobile rectangular base constituted by a motor home, trailer, or the like is overlain by a congruent cover. A foldable post is provided extending between each corner of the cover and the corresponding corner of the base so that when unfolded they rigidly support the cover well above the base. Walls constituted by a plurality of rigid panels can be pulled from the base or from the cover and slid along guides on the posts to enclose the structure. Hydraulic cylinders are provided to fold and unfold the posts so as to lower and raise the cover. When the walls are locked in place the entire assembly is rigid and self-supporting.
