Abstract
Abstract A collapsible building which is mounted on the platform of a conveyance has a first elongated unit which is mounted on the platform, and a pair of collapsible elongated units which flank the first unit when the building is fully erected. Each collapsible unit has a base portion including a floor and sidewalls, and a separable roof. The roof is connected to the respective base portion by two pairs of links at the front and rear ends of the respective collapsible unit and each base portion is pivotable relative to the first unit about a horizontal axis extending along the respective side adjacent to the bottom of the first unit. The links compel the roofs to move relative to the respective base portions when the base portions are pivoted by hydraulic motors between upright positions adjacent to the respective sides of the first unit and second positions in which they confine of the first unit. The roofs remain at least substantially horizontal during pivoting of the respective base portions and the roofs overlie the first unit in the second positions of the respective base portions.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
185 words
A collapsible building, comprising a first unit having a first side and a second side; a second unit including a base portion and a roof which is separable from said base portion; a joint pivotally connecting said base portion to said first unit for movement about a horizontal axis which is adjacent to and extends along one side of said first unit so that said base portion is movable through a plurality of intermediate positions between an upright first position adjacent to said one side of the first unit and a second position in which one of said units is at least substantially within the confines of the other of said units; and guide means for imparting to said roof a movement along a predetermined path relative to said base portion and in response to movement of said base portion so that the roof is located at a level above the base portion in the first position and above said first unit in the second position of said base portion, the movement of said roof having a component in a direction transversely of said axis.
Claim 2
Dependent Claim
185 words
A collapsible building, comprising a first unit having a first side and a second side; a second unit including a base portion and a roof which is separable from said base portion; a joint pivotally connecting said base portion to said first unit for movement about a horizontal axis which is adjacent to and extends along one side of said first unit so that said base portion is movable through a plurality of intermediate positions between an upright first position adjacent to said one side of the first unit and a second position in which one of said units is at least substantially within the confines of the other of said units; and guide means for imparting to said roof a movement along a predetermined path relative to said base portion and in response to movement of said base portion so that the roof is located at a level above the base portion in the first position and above said first unit in the second position of said base portion, the movement of said roof having a component in a direction transversely of said axis.
Claim 3
Dependent Claim
29 words
The building of claim 1, wherein said roof is at least substantially flat and is at least substantially horizontal, at least in the second position of said base portion.
Claim 4
Dependent Claim
69 words
The building of claim 2, wherein said first unit has a front side and a rear side and said guide means comprises a first pair of links at the front side and a second pair of links at the rear side of said first unit, each of said links having a first portion articulately connected to said base portion and a spaced-apart second portion articulately connected to said roof.
Claim 5
Dependent Claim
55 words
The building of claim 3, further comprising a bearing disposed between the first and second sides of said first unit at a level below said roof, said guide means further comprising an elongated connecting member having a first end portion articulately connected to said bearing and a second end portion articulately connected to said roof.
Claim 6
Dependent Claim
21 words
The building of claim 4, further comprising a mobile platform for said first unit, said bearing being provided on said platform.
Claim 7
Dependent Claim

The building of claim 1, further comprising means for moving said base portion between said first and second positions, including at least one fluid-operated motor having two components which are movable relative to each other, one of said components being connected to said first unit and the other of said components being articulately connected to said second unit.
Claim 8
Dependent Claim
40 words
The building of claim 6, wherein said motor is disposed at a level below said first unit and said second unit further comprises an arm provided on said base portion and articulately connected to the second component of said motor.

The building of claim 6, wherein said second component forms part of said guide means.
Claim 12
Dependent Claim
57 words
The building of claim 6, wherein said guide means comprises an elongated connecting member having a first end portion pivotable about a fixed axis and a second end portion articulately connected to said roof, said second component being arranged to pivot said connecting member and to thereby move said base portion between said first and second positions.
Claim 13
Dependent Claim
47 words
The building of claim 1, further comprising means for moving said base portion between said first and second positions, including a lever pivotable about a fixed axis and having an arm, a link coupling said base portion with said arm, and motor means for pivoting said lever.
Claim 14
Dependent Claim
31 words
The building of claim 12, wherein said lever has a second arm and said motor means includes a double-acting cylinder and piston assembly located at a level below said first unit.
Claim 15
Dependent Claim
201 words
The building of claim 1, further comprising a third unit including a base portion and a roof which is separable from the respective base portion, a joint pivotally connecting the base portion of said third unit to said first unit for movement about a horizontal axis which is adjacent to and extends along the other side of said first unit so that the base portion of said third unit is movable through a plurality of intermediate positions between an upright first position adjacent to said other side of the first unit and a second position in which one of said first and third units is at least substantially within the confines of the other of said first and third units, and guide means for imparting to the roof of said third unit a movement along a predetermined path relative to the base portion of said third unit in response to movement of the base portion of said third unit so that the roof of said third unit is located at a level above the base portion of the third unit in the first position and above said first unit in the second position of the base portion of said third unit.
Claim 16
Dependent Claim
