Definitions

  • This invention relates broadly to the art of vehicle parking apparatus, and more specifically to vertical vehicle parking structures.
  • a parking tower includes a frame defining vertically positioned cubicles and an elevator for moving vehicles vertically between a ground (street) level and the cubicles.
  • the elevator and the cubicles include horizontal conveyors for moving the vehicles between the elevator and the cubicles when the elevator is positioned respectively adjacent to the cubicles.
  • the horizontal conveyors include a clutch mechanism for providing linkage between the horizontal conveyors so that only one motor assembly is required for moving the horizontal conveyors.
  • a control system controls an elevator drive motor assembly and the horizontal-conveyor motor assembly to automatically move cars between the ground level and a selected cubicle in response to actuation thereof at or near the ground level.
  • the horizontal conveyors are endless conveyors which are mounted on easily removable rollers.
  • idler roller mounts include non-round shafts which slidably engage openings in U-shaped frames.
  • the rollers include bearings allowing the outer surface of the rollers to revolve about the shafts.
  • the control system includes automatic lever- type wheel chocks which are activated by a solenoid.
  • the control system further includes an elevator vertical stopping assembly which has an activated radiation source at a selected floor to inform the elevator when it should stop and a safety stop latch to mechanically latch the elevator to the floor at the correct position and thereby assure engagement of the horizontal-conveyor clutch.
  • a parking tower 10 includes a frame 11 which defines cubicles 12a-t and an elevator shaft 14.
  • the parking tower 10 also includes a vehicle elevator 16 - having an elevator platform 18.
  • the elevator 16 is supported by eight cables 20 which respectively extend about eight pulleys 22 to four counterweights 24.
  • a motor 26 drives the elevator 16 via two grooved pulleys 27 and cables 27a (shown in both solid and dashed lines in Fig. 5A to illustrate positions at different positions of the elevator 16) riding in pulleys 27b.
  • a multiple selection unit 30 is shown in more detail in Fig. 6.
  • the multiple selection unit 30 is connected to the elevator vertical motor 26 via a control unit 32.
  • the control unit 32 is also coupled to a horizontal-conveyor motor and control switches 34 mounted in the elevator platform 18, as well as to radiation sources 28 at each floor and limit switches, sensors and controls 29 at the horizontal conveyor of each cubicle (all connections not shown in Fig. 5).
  • a vehicle operator has a key to a front door of the parking tower 10 and can therefore open the door and drive his vehicle 36 onto the vehicle elevator 16.
  • the operator looks at the multiple selection unit 30 (shown in detail in Fig. 6) and can see from illuminated red or green lights 38 and 40 which cubicle is free, with the buttons 42 numbered 1 through 20 in Fig. 6 corresponding to cubicles 12a-t in Fig. 5.
  • the operator sees which cubicle is free (a cubicle with a green light 40 beside it), he depresses a numbered button 42 corresponding to the cubicle to program the system and a button 44 to activate the system to lift his vehicle 36 and store, or park, it in the chosen cubicle.
  • the control unit 32 (Fig. 5) is now programmed and, in preparation for a coming "action" command, the control unit turns on a radiation source 28 just below the sixth floor (the floor at which the chosen cubicle 12k is located).
  • the operator then depresses the action button 44 on the multiple selection unit 30 and the control unit 32 sends a start signal to the motor 26 which drives the motor 26 to raise the elevator platform 18.
  • a timer 45 in the control unit 32 determines when the platform 18 is nearing the designated sixth floor, at which time, the control unit 32 communicates to the motor 26 to slow down.
  • a sensor 45a on the platform comes adjacent to the radiation source 28 and senses its presence. This sensing is communicated to the control unit 32 which in turn stops the motor 26 and also activates a latch 45b on the elevator.
  • the latch 45b moves to an extended position (not shown) for blocking movement of the platform beyond the designated floor.
  • the platform 18 normally comes to a stop without the latch 45b actually engaging a corresponding stationary member on the frame 11, but the latch 45b is intended as a safety mechanism to insure that the platform 18 does not move beyond the designated floor. In this regard, at this point in the cycle the platform 18 is moving so slowly that even if the latch does come in contact with the blocking member (not shown) the latch is not damaged.
  • control unit 32 Once the control unit 32 is aware that the elevator is at.its desired vertical position, it informs a horizontal-conveyor motor and control switches 34 on the elevator 16 to motivate a horizontal conveyor of the elevator 16 to move the vehicle 36 to the right, as viewed in Fig. 5, toward the cubicle 12k. Once at the cubicle 12k the vehicle 36 is transferred to a horizontal conveyor in the cubicle 12k and continues to be conveyed to the right until the vehicle 36.is fully in the cubicle 12k. Sensor switches 29 monitor the position of the vehicle and inform the control unit 32 when the vehicle is fully in the cubicle 12k. At this point, the horizontal conveyors are deactivated, the latch 45b is deactivated, and the elevator 16 is returned to ground level.
  • Fig. 1 is a partially-cut-away top view of the elevator platform 18 when it is positioned at the horizontal level of cubicles 12k and 12L.
  • An arrow 48 illustrates the direction from which a vehicle to be parked is driven onto and off of the elevator 16 when the elevator 16 was at the ground level.
  • the elevator platform 18 includes fixed support members 50 and 52, treads 56 and 58, frame members 60, 60a, 62 and 62a (Fig. 2), endless conveyors 64 and 66, and endless conveyor drive mechanisms 68.
  • a vehicle to be parked is driven across the fixed support member 50, the endless conveyor 64, and the treads 56 and 58, until the front wheels of the vehicle are resting on the endless conveyor 66, and the back wheels thereof are resting on the endless conveyor 64.
  • an automatic chock mechanism 65 (Figs. 1 and 2) is pivoted upwardly to prevent the vehicle from rolling backwardly.
  • the front of the vehicle is also chocked, however, the front-wheel chock 67 is stationary rather than being selectively, automatically operated as with the automatic chock mechanism 65 for the rear wheel.
  • the automatic chock mechanism 65 includes a wheel contact lever 65a (Fig. 2), a pivot joint 65b, a linkage lever 65c and a solenoid 65d.
  • the solenoid 65d is energized to pull backwardly on the linkage lever 65c and thereby cause the rigidly attached wheel contact lever 65a to pivot upwardly about the pivot joint 65b.
  • the linkage lever 65c is approximately 40cm long (although it does not appear so in Fig. 2) while the wheel contact lever 65a is approximately 25cm long.
  • the solenoid 65d pulls with a force of 12 pounds, which is sufficient force, with the mechanical advantage, to prevent undriven vehicles from rolling backwardly.
  • the endless-conveyor drive mechanism 68 (Fig. 1) comprises a motor 70 having a drive shaft 72 with two sprockets 74 and 76 thereon, two chains 78 and 80 which respectively mesh with the sprockets 74 and 76, and sprockets 82 and 84 which are respectively driven by the chains 78 and 80 and which are linked to traction rollers 86,88 and 90,92 via drive shafts 94 and 96.
  • These drive shafts 94 and 96 include rigid couplers 97 which allow the shafts 94 and 96 to be disassembled for removal.
  • the motor 70 is reversible so that it can be ordered by the control unit 32 to drive the endless conveyors 64 and 66 in either direction. With regard to the endless conveyors 64 and 66, they comprise the traction rollers 86, 88, 90 and 92, idler rollers 98, and conveyor belts 100 and 102.
  • the cubicles 12k and 12L also include endless conveyors 104 and 106 (only the structure for cubicle 12L will be described inasmuch as the structures of cubicle 12L and 12k are identical).
  • Traction rollers l08 and 110 respectively of endless conveyors 104 and 106 are driven by a drive shaft 112 which is, in turn, driven by a gear 114.
  • a chain 116 interconnects the drive shaft 112 with an opposite drive shaft 118, via sprockets 120, so as to apply power from both ends of the conveyors 104 and 106 to convey in either direction.
  • the motor 70 is utilized to apply power not only to the elevator-platform endless conveyors 64 and 66, but also to the cubicle endless conveyors 104 and 106.
  • a solenoid 122 (shown in detail in Fig. 4) is energized to pull a plunger 122a to the right, as viewed in Fig. 4, and thereby pivot levers 123 about pins on which they are mounted with slots, to move clutch gears 124 and 126 into intermeshing positions between a gear 128 attached to the drive shaft 96 and the gear 114 attached to the drive shaft 112.
  • FIG. 4 is a simplified view and that not all of the guiding mechanism for guiding the pivoting gears is shown.
  • the clutch gears 124 and 126 transmit power from the gear 128 to the gear 114 to thereby drive the endless conveyors 104 and 106 of the cubicle 121.
  • a spring 130 returns the clutch gears 124 and 126 to inactive positions depicted in Fig. 4.
  • the latches 45b insure that there is proper alignment between the elevator platform 18 and the associated cubicle so that the clutch mechanism can properly engage.
  • the conveyor belts 100 and 102 are mounted on the traction rollers 86, 88, 90 and 92 and on idler rollers 98.
  • Each of the idler rollers 98 are mounted on U-shaped support frame members 60, 60a, 62 and 62a, as is depicted in Fig. 2A, and in more detail in Figs. 8, 9 and 10.
  • the U-shaped support frames 60, 60a, 62 and 62a have holes 129 through opposite arms thereof to slidably, but snugly, receive roller shafts 131 which are held in position in the U-shaped frames by pins 131a extending through the shafts 131.
  • each roller there is a separate shaft 131 at each end of each roller, with the shaft extending through bearings 131b in the roller.
  • an inner race 131c of each of the bearings has an internal bore 131d which has a hexagonal shape to fit the outside shape of the respective shaft 131.
  • the shafts 131 are not round so that they will not turn in the snug holes 129 of the U-shaped support frames 60, 60a, 62 and 62a.
  • the purpose of this arrangement is to allow the idler rollers 98 to be easily removable from the frame by simply removing the pins 131a from the shafts 131 and sliding the shafts 131 longitudinally away from the rollers 98.
  • the U-shaped support frames have a width of approximately 8cms and the tolerance between holes through the frame and the shafts are l/2mm.
  • the U-shaped support frames 60, 60a, 62 and 62a are constructed of 14 gauge steel sheets which are cut in flat blanks, punched to make the hexagonal-shaped, shaft-receiving holes 129, and then bent to the U-shaped configuration depicted in Figs. 8 and 9.
  • the traction rollers 86, 88, 90 and 92 are not mounted in this manner because their shafts 94 and 96 must be driven and, therefore, the shafts 94 and 96 must rotate in support frames. Thus, the shafts 94 and 96 for these rollers are round.
  • vertical slots 135 are cut in the U-shaped support frames 60 and 60a for allowing the round shafts 94 and 96 to be easily mounted in and dismounted from the support frames 60 and 60a.
  • Bearings 135a are bolted or screwed to the frames 60 and 60a at the slots 135 for rotatably mounting the shafts 94 and 96.
  • the shafts 94 and 96 are removed from the frames 60 and 60a by unscrewing the bearings 135a from the frames 60 and 60a and disassembling the shafts 94 and 96 at the rigid couplers 97 (Figs. 1 and 2).
  • adjustable idler rollers 131e are also somewhat different in that these rollers can be moved laterally for tightening the belts 100 and 102.
  • the U-support frame openings for supporting the adjustable idler rollers 131e are slots 133 in which shafts 131f can slide laterally.
  • the shafts 131f are hexagonal in cross-sectional shape throughout most of their length until they reach the outside wall 131g of the U-shaped frame 131a. At this point, the shafts 131f turn into a threaded shaft 131h.
  • a nut 131k can be screwed onto this threaded shaft 131h to clamp the shafts 131f to the outside wall 131g of the U-shaped support frame 60a.
  • This arrangement allows the adjustable shafts 131f to be used to tighten the belts 100, 102 and 106, and also allows the adjustable idler rollers 131e to be easily removable by unscrewing the nuts 131k and sliding the adjustable shafts 131h into the adjustable idler rollers 131e.
  • this drawing depicts a motor-driven contact unit which is part of the control unit 32.
  • a motor 132 is energized to rotate a contact drum 134.
  • the motor 132 continues to rotate the drum 134 until appropriate contacts 136 close with contacts 138 to start the next procedure (for example to order the elevator position sensor and controller 28 to raise the elevator 16 to a certain level).
  • the contact-unit motor 132 turns off and waits for the appropriate function to take place, after which the motor 132 again turns on until appropriate circuits are closed to begin a new function.
  • the parking tower of this invention is uncomplicated in structure, but yet highly efficient and useful in operation. It should be noted that the parking tower, although it performs many functions, only requires two motor assemblies, one to drive the elevator 16, and the other to drive all of the horizontal conveyors.
  • the parking tower of this invention is automated to the point that it can be operated by vehicle drivers themselves without requiring the services of maintenance personnel. In addition, the drivers need not go with their vehicles to the parking places.
  • the parking tower of this invention provides a great deal of parking space although it uses very little ground space.
  • the structure described in this invention is sturdy, but yet is relatively easy to build.
  • the conveyor structure allows the horizontal endless conveyor to be relatively easily disassembled for repair.
  • controlling system of this automotive vehicle parking tower has redundant and safety features built in, although the overall system is not unduly complicated.
  • the parking tower of Fig. 5 has a 8.50 meter front by 6.50 meter depth.
  • the tower has a 10-level height, with each level being 2.20 meters in height (interior height).
  • the tower could also have a depth up to 19.50 meters so as to provide a plurality of cubicles on each side of the elevator shaft 14 at each level.
  • the tower is generally structured in a quadrangular prismatic shape, however it could be constructed in a multiple variety of shapes, measures and thicknesses.
  • the tower is capable of allowing parking for 20, 40, etc. automobiles, depending on the depth of the tower, without the assistance of service personnel.
  • switchboard, or multiple selection unit 30 is normally mounted on the exterior of the tower, adjacent the access gate of the tower, numerous other positions therefor could be used. However, it is desirable that a vehicle operator not have to accompany his vehicle to a parking space, as is set forth above.
  • an access door to the tower will usually remain closed, only to be opened upon insertion of a corresponding key in the switchboard, or multiple selection unit 30.
  • a control card could also be used.
  • Red and green lights on the multiple selection unit 30 change accordingly when vehicles occupy, or vacate, cubicles.
  • the tower is made of steel beams which are covered by sheet steel.
