Abstract
Abstract A lift for installation against a substantially vertical wall, comprising a support adapted to be mounted against said wall so as to extend substantially vertically along said wall, a plurality of shaft sections adapted for unilateral mounting one above the other against said support so as to form a continuous shaft, guide members in each shaft section positioned so that the aligned guide members of the successive shaft sections form a continuous guideway extending alongside said support, and a lift car adapted to be unilaterally guided along said guideway.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
166 words
A lift for installation against a substantially vertical wall, comprising a support adapted to be mounted against said wall so as to extend substantially vertically along said wall, a plurality of shaft sections each formed of interconnected peripheral elements surrounding an interior of the shaft section, means for interconnecting said shaft sections in axial alignment one above the other so as to form a continuous shaft, means for securing said shaft sections to said support, guide members within the interior of each shaft section positioned so that the aligned guide members of the successive shaft sections form a continuous guideway within the interior of said shaft, the guide members of each shaft section comprising two parallel guide beams, the cross section of each of which comprises a closed rectangular part plus a channel part facing the other beam and a channel part facing away from said other beam, a lift car within the interior of said shaft, and means movably interconnecting said car and said guideway.
Claim 2
Dependent Claim
166 words
A lift for installation against a substantially vertical wall, comprising a support adapted to be mounted against said wall so as to extend substantially vertically along said wall, a plurality of shaft sections each formed of interconnected peripheral elements surrounding an interior of the shaft section, means for interconnecting said shaft sections in axial alignment one above the other so as to form a continuous shaft, means for securing said shaft sections to said support, guide members within the interior of each shaft section positioned so that the aligned guide members of the successive shaft sections form a continuous guideway within the interior of said shaft, the guide members of each shaft section comprising two parallel guide beams, the cross section of each of which comprises a closed rectangular part plus a channel part facing the other beam and a channel part facing away from said other beam, a lift car within the interior of said shaft, and means movably interconnecting said car and said guideway.
Claim 3
Dependent Claim
198 words
A lift for installation against a substantially vertical wall, comprising a support adapted to be mounted against said wall so as to extend substantially vertically along said wall, a plurality of shaft sections each formed of interconnected peripheral elements surrounding an interior of the shaft section, means for interconnecting said shaft sections in axial alignment one above the other so as to form a continuous shaft, means for securing said shaft sections to said support, guide members within the interior of each shaft section positioned so that the aligned guide members of the successive shaft sections form a continuous guideway within the interior of said shaft, a lift car within the interior of said shaft, and means movably interconnecting said car and said guideway, each shaft section comprising at least one horizontal rectangular frame and four upstanding posts, all of which are formeD by hollow rectangular section beams which are connected at right angles in the corners of the box like structure, recesses being formed at the ends of at least some of the hollow beams of each shaft section such that lateral arms of multi-armed connecting plugs inserted into the hollow beams can extend through said recesses.
Claim 4
Dependent Claim
198 words
A lift for installation against a substantially vertical wall, comprising a support adapted to be mounted against said wall so as to extend substantially vertically along said wall, a plurality of shaft sections each formed of interconnected peripheral elements surrounding an interior of the shaft section, means for interconnecting said shaft sections in axial alignment one above the other so as to form a continuous shaft, means for securing said shaft sections to said support, guide members within the interior of each shaft section positioned so that the aligned guide members of the successive shaft sections form a continuous guideway within the interior of said shaft, a lift car within the interior of said shaft, and means movably interconnecting said car and said guideway, each shaft section comprising at least one horizontal rectangular frame and four upstanding posts, all of which are formeD by hollow rectangular section beams which are connected at right angles in the corners of the box like structure, recesses being formed at the ends of at least some of the hollow beams of each shaft section such that lateral arms of multi-armed connecting plugs inserted into the hollow beams can extend through said recesses.
Claim 5
Dependent Claim
36 words
A lift according to claim 2, in which the recesses for the lateral arms of the connecting plugs are provided at the two inwardly facing sides of the lower vertical hollow beam of each corner connection.
Claim 6
Dependent Claim
141 words
A lift for installation against a substantially vertical wall, comprising a support adapted to be mounted against said wall so as to extend substantially vertically along said wall, said support comprising a pair of vertical box shaped beams connected at regular spacings by cross beams, a plurality of shaft sections each formed of interconnected peripheral elements surrounding an interior of the shaft section, means for interconnecting said shaft sections in axial alignment one above the other so as to form a continuous shaft, means for securing said shaft sections to said support, guide members within the interior of each shaft section positioned so that the aligned guide members of the successive shaft sections form a continuous guideway within the interior of said shaft, a lift car within the interior of said shaft, and means movably interconnecting said car and said guideway.
Claim 7
Dependent Claim
141 words
A lift for installation against a substantially vertical wall, comprising a support adapted to be mounted against said wall so as to extend substantially vertically along said wall, said support comprising a pair of vertical box shaped beams connected at regular spacings by cross beams, a plurality of shaft sections each formed of interconnected peripheral elements surrounding an interior of the shaft section, means for interconnecting said shaft sections in axial alignment one above the other so as to form a continuous shaft, means for securing said shaft sections to said support, guide members within the interior of each shaft section positioned so that the aligned guide members of the successive shaft sections form a continuous guideway within the interior of said shaft, a lift car within the interior of said shaft, and means movably interconnecting said car and said guideway.
Claim 8
Dependent Claim
25 words
A lift according to claim 4, in which the support comprises a plurality of sections mounted in line with and on top of each other.
Claim 9
Dependent Claim
183 words
