Description

These The invention relates to a car capable of motor vehicles in an automated parking lot with different parking spaces too transport. More specifically, the car, as the subject of the invention, can automatically a vehicle from the entrance of the parking lot to a predefined parking space - even with Help of a lift - and then from this parking space out to the exit of the parking lot.

BACKGROUND THE INVENTION

Of the current The prior art includes a car, the motor vehicle in one automated parking lot, such as in US-A-3,435,965, which has an underground car park or includes a parking garage, which includes many parking spaces, where in each one a motor vehicle can turn off. With the help of the car you can the motor vehicle, that of the customer at a transfer point was parked at the entrance, record and in a free parking lot park. In later Consequence, the car can pick up the vehicle again and it for Take off point at the exit. To perform these steps can, the automated car can position itself under the motor vehicle lift it off the ground and carry it on reserved lanes.

With The conventional car can be the front wheels Motor vehicle lift to this from one place to another within to move the park, but the rear wheels on Stay ground.

These Cars can but do not align the motor vehicle and this proves to be especially in automated parks as a problem where the width of each single parking space very limited is and you have the available seats would like to exploit optimally.

to Have time namely Motor vehicle and wagon are aligned by the customer himself by this at the handover of the motor vehicle must ensure that the motor vehicle is correct at the transfer point was positioned. This approach is subjective and therefore not very reliable.

A incorrect positioning of the motor vehicle with respect to the car can cause an imbalance in the moving parts of the car to lead, damage at the Kaftfahrzeug and at the park cause or also a danger for representing the other customers and the staff at the parking lot.

Out that's why in automated parks, the cars without automatic centering the motor vehicles, the parking spaces be very wide. In terms of to the required width no parks with big ones capacity be built.

This Applicant has planned and concretized this invention, difficulties with automated cars - like those that have been used so far - to be overcome and gain further benefits from it.

SUMMARY THE INVENTION

These Invention is disclosed and it is characterized by the main claim out while the ancillary claims describe further innovative features of the invention.

One The object of the invention is to provide a self-propelled cart for automated To provide parks that are capable, fast and completely safe the parking and the return Any car, without regard to the sizes of consideration to have to take.

One Another goal is to reduce the parking space width, which is the capacity of the automated parking system would increase at the same size.

One Another object of the invention is to provide a car that is simple can also be used in existing parks.

With The car of this invention can be any motor vehicle lift and center it in relation to the cart to evenly distribute the load and a danger of clients and a damage on motor vehicles and parks.

Of the Cart - as Subject of the invention - can under the one to be transported Motor vehicle be positioned. He is also with lifting devices equipped with which the motor vehicle to a predefined Height of Floor can be lifted off. Position the alignment devices bring the vehicle correctly to the car and the conveyors it on the reserved lanes of a place of the park to another. The extremely limited maximum width of the car and its Skill in centering the reversed motor vehicle, contribute to the fact that compared to the existing parks receives much narrower parking spaces with conventional cars.

For example, a car lt. He and under working conditions a maximum width of about 180 cm. As a result, the width of the parking space can be reduced to around 200 cm. Comparatively, you need 230-250 cm for the parking space when using the conventional car.

The Lifting devices include according to the invention on each wheel of the motor vehicle a pair of arms positioned at a certain height from the ground which are able to move selectively between a resting position, they do not use the wheels of the motor vehicle and a working position, in they are on the other side in relation to the axis of the wheel to move. They approach gradually one another until they reach the predefined distance to have.

This Distance is below the value of the wheel diameter and the height of the arms from the ground is below the wheel radius.

The Alignment devices according to the invention activate only after all wheels of the motor vehicle were lifted off the ground. They belong to each pair of wheels in opposite position with respect to the longitudinal axis of the motor vehicle, two pushers that are in the opposite direction outward can move in the direction of the respective wheel.

The Pushers can move the motor vehicle laterally, taking as long as the inner part of the wheel is worked until the longitudinal axis of the motor vehicle and the reference axis of the carriage, for example the middle axis, coincide.

each Push element is located between a pair of arms and contributes to it at that, the wheels slide sideways on the arms.

Corresponding invention, the arms are designed so that the lateral sliding as well as the lifting of the wheels be relieved.

In In one application, the arms comprise at least one roller with a roller dead path that supports the hub of the wheel. The surface, the supporting the lateral sliding of the wheel is done carefully.

In another application of the invention are the opposite Pushers that define the same pair, capable of over the Outstretch cars to the same extent; in this way the longitudinal axes are correct of the car and the motor vehicle when the two pushers touch the respective wheel.

in the preference example the invention is the car with independent front lifting devices and independent front Aligning devices and rear alignment devices provided.

To Another feature of the invention is that the lifting devices rear and the alignment devices behind or the lifting devices the front and the front alignment devices are capable of their Change position along the car, so that they are each Center distance of the wheels adjust the adjusted to be adjusted vehicles.

DETAILED DESCRIPTION OF THE PREFERENTIAL EXAMPLE

The 1 shows an automated parking facility 10 , which includes a vertical structure in which a variety of parking spaces 13 , a transfer point 11 , a collection point 12 , a lift 14 and a car 20 can be accommodated according to the invention.

The car 20 is capable of a motor vehicle 15 from the area of the points 11 and 12 , from the lift 14 and from the parking spaces 13 pick up and this from one point to another within the parking lot 10 to transport.

During the parking process, the car can 20 the motor vehicle from the transfer point 11 in the lift 14 transport and from there to a predefined parking space 13 , When picking up he can the motor vehicle 15 from the mentioned parking space 13 in the lift 14 bring and from there to the collection point 12 ,

The car 20 and the lift 14 move completely automatically and are controlled by a programmable control unit, which is not shown in the drawings.

The car 20 lt. Invention has a support frame 16 whose shape allows it to be under the motor vehicle 15 can position without interference. In this case, the points are 11 and 12 , the parking spaces 13 and the lift 14 with its own channel 19 ( 5 - 13 ) in which the car is 20 over the wheels 17 can move around under the motor vehicle 15 to position.

The front wheels 17 are with an electric motor 22 which is controlled by the control unit on the basis of the signals received from the corresponding limit stops. The end stops, which are not shown here, are located inside the channel 19 or on the frame 16 ,

The motor 22 is equipped with a device that allows you to regulate the acceleration and braking, so that the car 20 no abrupt movements subject to the safety of the motor vehicle 15 could influence.

The frame 16 defines a box-like structure in which the functional parts of the two lifting devices, front 18a and behind 18b , can be accommodated. With these, the motor vehicle 15 from the ground 21 be lifted off. With the help of the two alignment devices, front 23a and behind 23b , the motor vehicle can 15 in relation to the car 20 ( 5 - 9 ) are centered.

In the application shown is the car 20 on each of the two long sides with wheels 24 ( 3 ), with a vertical axis of rotation and a dead path. He can walk along the side walls of the canal 19 slide and thus take along the carrying rack 16 on the mentioned walls ( 5 - 9 ).

Every lifting device 18a and 18b has two pairs of horizontal arms 26 , each on the top of the frame 16 near the long side and on the opposite sides with respect to the longitudinal axis 25 of the carriage 20 ( 2 ) is positioned.

Every arm 26 supports a roller 27 with a dead path perpendicular to the top of a vertical pin 28 is coupled, the - as described above - on a reversible electric motor 29 connected.

The electric motor 29 Controlled by the corresponding end stops, which are not shown here, is capable of the pins 28 to turn to each arm 26 to bring selectively into two different positions: a first position or rest position in which the arm 26 parallel to the longitudinal axis 25 of the carriage 20 is positioned, taking inside the bulk of the support frame 16 held, and a second position, or working position, in which the arm 26 perpendicular to the longitudinal axis 25 is positioned over the support frame 16 protrudes.

Loud 2 are the arms 26 that the same pair of lifting devices ( 18a or 18b ), ie those on the same side of the car 20 are positioned, able to move against each other to a wheel 55 of the motor vehicle 15 to grab and off the ground 21 ( 3 ).

The wheel 55 is lifted without causing damage to the tires or other parts of the vehicle 15 arises as the rollers 27 with a dead path are able to the profile of the wheel 55 to follow, regardless of the width and diameter "D", and in constant contact with him.

The poor 26 are able to approach each other at a distance "x", which is below the diameter "D" of the wheel 55 and its height "h" from the ground 21 off lies below the radius "r" of the wheel 55 ( 3 . 5 ).

In this case, the engine is 29 via a kinematic chain with the four vertical pins 28 connected. The kinematic chain includes two bevel gears 31 with which the shaft 30 of the motor 29 with the respective lower transverse waves 32 and two bowden cables 50 can be connected, for example, formed by bands or chains, which are each lower cross-shaft 32 with the upper cross shaft 33 can connect.

The two ends of the upper cross shaft 33 are about the respective bevel gear 34 , with the corresponding vertical pin 28 the two arms 26 connected, mirror-like to the longitudinal axis 25 ( 6 ) are.

While the lifting device 18a with the support frame 16 firmly connected, can in the car 20 the invention, the rear lifting device 18b along the same frame 16 between a position in the 3 indicated by a dashed line, in which they are at a minimum distance "d1" from the front lifting device 18a is located and a position in the 3 is characterized by a continuous line in which it is at a maximum distance "d2" from the front lifting device 18 ° move. This allows the adaptation of the car 20 at the wheelbase of the wheels 55 of the motor vehicle 15 and therefore the lifting and carrying of each type of motor vehicle.

In this case, the lifting device 18b on a sliding surface 35 installed where they are on the rack 16 by means of lower wheels 36 which are capable of on the lower inner wall of the frame 16 to stay and by means of side wheels 37 which are able to slide on the lateral inner walls of the frame 16 to stay ( 9 ).

The sliding surface 35 comes with a reversible electric motor 38 , the fix on the frame 16 is, along the frame 16 postponed.

In this case, the engine is 38 over the chains 40 with two parallel threaded rods 39 connected, which are coupled to the two ends and free on the support frame 16 ( 2 ) can rotate.

The two threaded rods 39 are in the respective elements 41 used, which are provided with nut screws and fixed to the sliding surface 35 are connected.

In this way comes the rotation of the engine 38 in one direction or the other, and as a result the two threaded rods also rotate 39 so that the rear lifting device 18b from the front lifting device 18a removed or approaching.

The front 18a and the rear lift 18b differ from each other in that the front 18a firmly on the support frame 16 is located while the rear device on the sliding surface 35 is installed.

In addition, the rear lifting device has 18b over a pair of inner arms 26 and a pair of outer arms 26 , in the direction of the carriage length 20 that are autonomous because they are equipped with independent engines; the first engine 29 Can the pair of interior arms 26 control while the second engine 52 the pair of outer arms 26 can control.

The front 23a and the rear alignment device 23b differ from each other because of the front alignment device 23a firmly with the carrying frame 16 connected while the rear alignment device 23b on the sliding surface 35 is installed.

Each alignment device 23a and 23b includes two push elements 42 at the outer end with the appropriate anchoring elements 51 are provided, which consist for example of elastic material or rubber.

The push elements 42 are parallel to each other. You can get by an electric motor 43 at right angles to the longitudinal axis 25 of the carriage 20 move each element in the opposite direction.

More precisely, every push element is 42 between a retraction position, in the 2 shown with a solid line in which the abutment 51 within the side edge of the car 20 located and a maximum extraction position in the 2 represented by a broken line in which the abutment 51 over a defined segment with respect to said side edge, protrudes, slidable.

The movement of the two push elements 42 same alignment device 23 via two pinions 45 that by an electric motor 43 to be controlled. Each one is capable on the respective rack 44 latch on, located on the inside of the two pushers 42 befandet.

In this case, the first pinion 45 at the top of a vertical shaft 48 wedged by the engine 43 via a bevel gear 47 controlled becomes. The second pinion 45 is on a vertical wave 49 wedged over a chain 46 is controlled and able to move on two gears that are on the shaft 48 or on the shaft 49 are wedged, to close.

The alignment devices 23a and 23b are activated after the motor vehicle 15 through the two lifting devices 18a and 18b lifted off the ground.

When this happens, then approach the two anchoring elements 51 same alignment device 23a or 23b the respective wheel 55 the same axis of the motor vehicle 15 ,

The first of the two anchoring elements 51 which the respective wheel 55 touches, it hits, as it does the entire motor vehicle 15 pushes outwards until the second anchoring element 51 the respective wheel 55 touched.

This is done in safe conditions and without any damage to the motor vehicle 15 arise because the anchoring elements 51 on the inner part of the wheel tire 55 Act.

The sliding of the tires on the rollers 27 the poor 26 is also due to the careful finish of the rollers 27 facilitated.

The two push elements 42 protrude equally over the overall structure of the car 20 in addition and if the two anchoring elements 51 the respective wheels 55 of the motor vehicle 15 Touch, then the center of the wheel axle 55 vertical with the longitudinal axis 25 of the carriage 20 aligned.

When this happens, both in accordance with the front alignment device 23a , as well as in accordance with the rear alignment device 23b , then the longitudinal axis of the motor vehicle is correct 15 with the longitudinal axis 25 of the carriage 20 match.

This allows perfect centering of the motor vehicle 15 on the car 20 and therefore he can park at the car park 10 be moved absolutely safely.

Now the different steps are analyzed, which the car 20 under the supervision of the programmable control unit is able to perform.

The collection and parking cycle helps keep the car 20 under the motor vehicle 15 that at the delivery point 11 was parked, positioned. This with the help of the arms 26 the lifting devices 18a and 18b in the rest position and the sliding surface 35 at the maximum distance to the front lifting device 18a is positioned. Then the arms will 26 the front lifting device 18a put into working position, leaving the front wheels 55 of the motor vehicle 15 be lifted from the ground. At this point are the arms 26 , which relates to the rear lifting device 18b in a reset position, in the working position of the engine 52 brought while the advanced are left in the resting position.

The lifting area 35 becomes the front lifting device 18a moved until the arms 26 in a reset position, the rear wheels 55 of the motor vehicle 15 touch. Then also the arms become 26 in advanced working position from the engine 29 brought into working position, so that the rear wheels 55 of the motor vehicle 15 from the ground 21 be lifted.

Now the car is 15 entirely from the ground 21 lifted. But before it gets to the parking space 10 is transported, it must be on the car 20 be centered.

For this purpose, the front alignment device 23a and the rear alignment device 23b activated at the same time, so that all anchoring elements 51 the pushers 42 the respective wheel 55 of the motor vehicle 15 touch. Under these conditions, the car can 20 from the delivery point 11 to the lift 14 and from this to a parking space 13 ,

When the car 20 the parking space 13 has reached, then the two push elements 42 brought into a retraction position and the two lifting devices 18a and 18b are disabled, for example, the rear 18b first and then the front 18a so the wheels 55 of the motor vehicle 15 in the parking space 13 stay on the ground and the car 20 to the transfer point 11 can return to start a new collection park cycle.

The collection cycle of the motor vehicle 15 from the parking space 13 and the subsequent handover at the collection point 12 is substantially as described above, except for centering the motor vehicle 15 on the car 20 , which may prove unnecessary if the motor vehicle 15 already in relation to the channel 19 the parking space 13 in a correct position.

The push elements 42 In any case, they can be brought into the pull-out position to ensure that the motor vehicle is stable during the transport phase.

The 10 - 13 show two under different applications, both at the transfer point 11 , as well as at the collection point 12 and at the lift 14 Can be used to the channel 19 close when the car 20 not available.

In the application of 10 becomes the channel 19 through two moving plates 53 closed. These can approach each other as long as they are on the center line of the canal 19 to meet.

In the variant of the 11 - 13 on the other hand is a shutter 54 provided at the two end, which is the channel 19 can close on its entire length.

According to this invention, the car 20 able to open and close the moving plates 53 or the shutter 54 to steer when it comes from the place or leaves where the moving plates 53 or the shutters 54 are mounted.

The 14 - 18 show another application of the car 20 according to the invention.

In this example, the electric motor 22 with a reduction unit 56 connected directly to the axle of the wheels 17 of the carriage 20 ( 14 and 16 ) connected is.

Every arm 26 is capable of using the corresponding reversible electric motor 57 that with a reduction gear 58 connected to which a vertical pin 28 connected to be moved ( 14 . 17 . 18 ).

The movement of the pushers of the alignment devices 23a and 23b is in this case by two reversible electric motors 59 ensures, with one with the longitudinal axis 25 is aligned and one is oblique to her.

Every electric motor 59 is capable of moving on the pushers 42 thanks to the corresponding bevel gearbox 60 to transfer that to the respective vertical shaft 61 acts.

The respective pinions 62 are on two vertical waves 61 attached, with each on the racks 43 the pushers 42 same alignment device 23a . 23b is engaged.

The sliding surface 35 always shifts thanks to an electric motor 38 that with a single threaded rod 39 is connected, which is in the axial position and with the corresponding element 41 , which is provided with a nut is connected.

The 19 and 20 show a variant of the invention in which each arm 26 the lifting devices 18a and 18b moved by the corresponding fluid-dynamic actuator 63 becomes.

In this example, every actuator is 63 with the respective arm 27 via a rocker arm 64 connected, which is capable of the vertical pin 28 on which the arm 27 is mounted, to turn.

Specifically, if the rods of the actuators 63 expand, then become the arms 27 in the rest position parallel to the longitudinal axis 25 of the carriage 20 held.

If, however, the rods of the actuators 63 retract, then turn the rocker arms 64 and also bring the vertical pin 28 to rotate and the arms 27 , which are in the working position, are perpendicular to the axis 25 ( 19 ).

In another variant, which is not shown here, also the pushers 42 moved over the fluid-dynamic actuators.

Of course you can modified this invention or with additions be provided. However, these have within the intended objectives to be done.

For example, the engines can 22 . 29 . 38 . 43 and 52 be connected to the respective parts so that they can be moved over the kinematic chains - which are of a different type than those shown here.

In addition, the sliding surface 35 be moved on the guides, as on rails, and not on the wheels. The sliding surface 35 may also be moved over systems other than those described herein (such as hydraulic or similar).

Also the rear lift 18b as well as the front lifting device 18a , can with only one engine 29 and be provided with decoupling devices connected to the shaft 30 connected, can be activated individually, so that the front and the rear arm 26 are independent of each other.

In addition, you can replace the moving plates 53 or the shutter 54 to access other means to the channel 19 in the absence of the car 20 to close; In another possible example, these means comprise a platform that can be selectively raised via hydraulic actuators or the like.

Although it is not shown or described here, it is also clear that the car 20 equipped with safety devices with end stops that precisely adjust each maneuver as well as photocells, sensors and micro-switches, the control unit the different phases of the car 20 signal.

Furthermore It is clear that even if the description on a concrete Example, a relevant Professional sure many more equivalent forms for automated Dare to find cars, but that these are always within the scope of objectives to move this invention, the here in the claims are defined.
