Abstract

A vehicle elevator and conveyor arrangement in a parking building of the kind in which the vehicle is intended to be conveyed in the building without the assistance of a driver. The conveyor arrangement includes a so-called transfer carriage which is intended to raise and lower all wheel of the vehicle and which can be moved in a horizontal plane in the building and also in a vertical direction by means of the elevator arrangement, which elevator arrangement includes an elevator platform for supporting a transfer carriage. Each of the stories or floors of the parking building on which a transfer carriage (31) is intended to be moved is provided with two parallel rails (50, 51) which form a horizontal transfer-carriage conveyor path or track (71). One or more elevator shafts (61, 62) are positioned along the longitudinal extension of the rails. The wheel (52-59) of the transfer carriage can be displaced from a position (55') in which the track width of the transfer carriage (31) corresponds to the distance between the running or bearing surfaces of the rails (50,51) to a position (55") in which the track width is smaller than this distance. The elevator platform includes a plate whose length (L) is shorter than the distance between the rails (50, 51). Lifting attachments project from the elevator platform (40) in the longitudinal direction thereof. The rails (50, 51) are interrupted in the vicinity of respective elevator shafts, so as to allow vertical passage of the lifting attachments. The longitudinal extension of each interruption in the rails (50, 51) is shorter than the axle distance between the wheels (52-59) of each wheel pair of the transfer carriage (31), so that a transfer carriage is able to pass an elevator shaft in the horizontal direction.

Vehicle elevator and conveyor arrangements for cars, in a multi-storied vehicle parking building of the kind in which a vehicle is moved to a parking space in said building, which includes a plurality of parking spaces, without the assistance of a driver and without being rolled, said conveyor arrangement including at least one transfer carriage which comprises a transport carriage, which in turn includes lifting devices constructed to raise and lower all wheels of the vehicle, said at least one transfer carriage being movable in a horizontal plane in the parking building and also in a vertical direction in said building by means of an elevator arrangement, which elevator arrangement includes an elevator platform for supporting a transfer carriage, characterised in that each of the floors or stories of the parking building on which a transfer carriage (31) is intended to be moved is provided with two mutually parallel rails (50, 51;

50', 51') which form a horizontal conveyor path (71) for said at least one transfer carriage (31), said at least one transfer carriage (31) being intended to be moved on said rails (50, 51;
50', 51.dbd.) by means of two wheel pairs (52, 53;
54, 55;
56, 57;
58, 59) located on each side of a transfer carriage which depicts a track width of said transfer carriage;
in that one or more elevator shafts (61, 62) are positioned at locations along the longitudinal extension of the rails;
in that the wheels (52-59) of a transfer carriage can be moved from a position (55') in which the track width of a transfer carriage (31) corresponds to the distance between the bearing surfaces of the rails (50, 51) to a position (55.vertline.) in which the track width of a transfer carriage is smaller than said distance;
in that the elevator platform (40) includes a plate whose length (L) is shorter than the distance between said parallel rails (50, 51);
in that lifting attachments (42-45) extend from the platform (40) in the longitudinal direction thereof;
in that said parallel rails (50, 51) are interrupted in the vicinity of each elevator shaft (61, 62) such as to allow vertical passage of the lifting attachment (42-45);
in that the longitudinal extension (46) of each interruption in the parallel rails (50, 51) is shorter than the distance between the axles of the wheels (52-59) of each wheel pair of a transfer carriage (31);
and in that elevator-platform lifting devices (48) are mounted on said lifting attachment (42-45).
