DESCRIPTION OF PREFERRED EMBODIMENT
With reference to the drawings and by way of example only there is provided vehicle stacking apparatus (generally indicated by arrow 1) comprising a plurality of vehicle parking bays (generally indicated by arrows 2), vehicle access points (3a, 3b), and a travelling vehicle lifter (generally indicated by arrow 4).
FIGS. 1 through 3 show two arrays (5a, 5b) of parking bays (2) in a spaced apart disposition to be serviced by a lifter (4) travelling between the arrays (5a, 5b). FIG. 3 shows parking bays (2) positioned in a non-regular arrangement, and wherein different height bays are also provided for differently sized vehicles.
FIG. 4 illustrates the access points (3a, 3b) with the travelling vehicle lifter (4) in a position to receive a vehicle. The parking bay arrays are stored in the building (8), such as also illustrated in FIG. 3. A command entry station (9) is provided for a driver to interface with the system in order to store or retrieve a vehicle. This may include payment means, such as a cash payment mechanism, and/or Electronic Funds Transfer (EFT) reader for banking and/or credit cards, etc. Such payment options are more likely for use in public places. In private garaging, security cards, keypads, and devices, etc. are morely likely to be used. Motion sensing equipment may be provided to ensure a vehicle appears unoccupied before it can proceed to storage.
FIGS. 5 and 6 illustrate a preferred embodiment of a travelling vehicle lifter (4). This comprises a supporting carriage (10) able to travel along rails (11). An electric motor (12) interacts with either a chain or cable to move the carriage (10) horizontally.
A vehicle platform (14) is supported at each corner by a mast (15) along which it can travel vertically; the masts acting as a guide for travel. A chain drive system (not visible) housed within the masts (15) is driven by a pair of electric motors (16) for raising and lowering the platform (14). Accordingly, in response to a control signal, the lifter (4) can travel horizontally while raising the platform (14) vertically for placing or retrieving a vehicle.
FIGS. 7 and 8 illustrate a conveyor assembly as is used in the parking bays (2), accessing points (3) and vehicle platform (14). The wheels of a vehicle (not shown) are positioned on the conveyor's tracks (17). An electric motor (18) driving connected rollers (19) move the tracks (17), as well as any vehicle thereon, either rearwardly or forwardly. By the use of such as arrangement, a vehicle can be transferred between either of an access point (3) or bay (2) and the vehicle platform (14).
FIGS. 9 and 10 illustrate the retrieval (or parking) of a vehicle (24) in a bay. In FIG. 9, the vehicle platform (14) of the lifter (4) is aligned with the bay (2) so that the conveyors (20) and (21) are aligned. The conveyors (20, 21) are operated so the car is moved onto the platform. Sensors may be provided to indicate that the vehicle is suitably positioned. The vehicle (24) is then in the position of FIG. 10. The supporting platform (14) and lifter (4) are operated to take the vehicle to the access point (3), or another position if required (e.g. service bay, or temporary placement), lowering the vehicle while travelling horizontally.
In FIG. 9, one of the bays (30) is a service bay. This may include a manually operated petrol pump operated by a valet. An access point (not visible) may be provided at the rear to allow for service people to retrieve and park vehicles required for servicing. The bay (30) may also comprise or feed to an automated car wash. The same conveyor system may be used for the car wash. 4
Each car parking bay can be modular units, as is shown in FIGS. 9 and 10. Each module can be added or subtracted from the structure, and the control system programmed accordingly. If necessary the tracks (11) for the carriage (10) can be extended.
FIG. 3 illustrates more of a framework type construction, which can be quickly assembled or disassembled for alteration or removal.
FIG. 11 illustrates a multiple depth parking bay structure, where parking bays (52) of more than one vehicle depth are used. The top bay shows where up to three compact cars (41) can be stored. The lower bay illustrates two larger vehicles (40) instead being stored. To accomplish this, multiple conveyors (41a-d) are used to allow individual vehicles to be moved (end one first for retrieval) for placement. This represents a variation for some situations.
FIG. 12 illustrates a curved or part circular parking bay structure, as a variation for certain situations (be it for land and space limitations, aesthetics, or other).
