Abstract
Abstract A self-supported mobile housing unit comprising an upper part including a box-like framed structure that is supported on the ground by wheels attached by supports to the framed structure. The upper part has stationary walls. A lower part, that is interconnected with the upper part, has a horizontally extending floor and at least one upper and one lower wall section. The lower part is vertically moveable so as to be contained in the upper part upon actuation of a lifting mechanism carried by the framed structure. Upon movement of the lower part including the floor, the lower wall section and upper wall section move vertically into a telescopic nested position with the stationary walls of the upper part to allow a motor vehicle to be received under the upper part between the supports and coupled to the mobile housing unit. The walls of the upper part and lower part may be provided with openings and a telescoping door to provide egress from and ingress to the mobile housing unit.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
143 words
A door for a mobile housing unit having an upper part and a lower part with an opening in each of said parts to define an entrance to said mobile housing unit, said door comprising at least two panels interconnected to allow for vertical movement between an extended position with one panel being in a contiguous relationship with respect to the other panel to a telescopic nested position with one panel being received within the other panel, said panels in an extended position closing off the openings in the upper part and the lower part and in a nested position said panels closing off only one of said openings, said one panel being hingedly connected to said mobile housing unit to allow for pivotal movement of said door between open and closed positions so as to allow access to said mobile housing unit.
Claim 2
Dependent Claim
143 words
A door for a mobile housing unit having an upper part and a lower part with an opening in each of said parts to define an entrance to said mobile housing unit, said door comprising at least two panels interconnected to allow for vertical movement between an extended position with one panel being in a contiguous relationship with respect to the other panel to a telescopic nested position with one panel being received within the other panel, said panels in an extended position closing off the openings in the upper part and the lower part and in a nested position said panels closing off only one of said openings, said one panel being hingedly connected to said mobile housing unit to allow for pivotal movement of said door between open and closed positions so as to allow access to said mobile housing unit.
Claim 3
Dependent Claim
189 words
A door for a mobile housing unit having an upper part and a moveable lower part, said lower part comprising at least one upper wall section and a lower wall section, openings being provided in said upper part, said upper wall section and said lower wall section to define an entrance to said mobile housing unit, said door comprising a first panel, a second panel, and a third panel interconnected to allow for vertical movement between an extended position and a nested position with said first panel being in a contiguous relationship with said second panel and said second panel being in a contiguous relationship with said third panel when in the extended position, and the third panel telescopically received in said second panel and said second panel telescopically received in said first panel when in the nested position, said panels when in an extended position closing off said openings in the upper part, said upper wall section and said lower wall section of said lower part, said panels, when in a nested position, closing off only one of said opening, said door hingedly connected to said upper part.
Claim 4
Dependent Claim
189 words
A door for a mobile housing unit having an upper part and a moveable lower part, said lower part comprising at least one upper wall section and a lower wall section, openings being provided in said upper part, said upper wall section and said lower wall section to define an entrance to said mobile housing unit, said door comprising a first panel, a second panel, and a third panel interconnected to allow for vertical movement between an extended position and a nested position with said first panel being in a contiguous relationship with said second panel and said second panel being in a contiguous relationship with said third panel when in the extended position, and the third panel telescopically received in said second panel and said second panel telescopically received in said first panel when in the nested position, said panels when in an extended position closing off said openings in the upper part, said upper wall section and said lower wall section of said lower part, said panels, when in a nested position, closing off only one of said opening, said door hingedly connected to said upper part.
Claim 5
Dependent Claim
144 words
The door for a mobile housing unit as described in claim 2 and which is further characterized in that said first and said second panels are hollow and has a guide system contained within said first and second panels, said guide system interconnecting said first panel to said second panel and said second panel to said third panel, said guide system being arranged so as to allow said panels to be telescopically positioned with the third panel telescopically received in said second panel and said second panel telescopically received in said first panel when said first, second, and third panels are in the nested position, and to allow said panels to be moved to the extended position so that said third panel is in a contiguous relationship with said second panel and said second panel is in a contiguous relationship with said first panel.
Claim 6
Dependent Claim
56 words
The door for a mobile housing unit as described in claim 3 and which is further characterized in that said guide system maintains said first panel, said second panel, and said third panel in one rigid vertical plane when in an extended position, said door being hingedly connected to said upper part at said first panel.
Claim 7
Dependent Claim
56 words
The door for a mobile housing unit as described in claim 3 and which is further characterized in that said first panel, said second panel, and said third panel when in the nested position closing off the opening in the upper part only, said door being hingedly connected to said upper part at the first panel.
