The present invention concerns the field of the automatic mechanic parking systems. In detail, the present invention concerns a vehicles transferring carriage for a mechanic automatic parking system.
In the mechanic automatic parking systems, the vehicles are left by the user in an entrance/exit room and from here automatically moved in the parking place time by time assigned, by means of transferring devices.
It is known in said parking systems to have a vehicles transferring device, generally composed by one or two transferring carriages, onto which the car to bed or to be extracted from the parking is loaded. The transferring carriage is normally positioned on a vertically and/or horizontally translating platform through which it can be moved into the required position, on the same level or on different levels of the parking.
From said position, the carriage is capable of transferring the vehicle, bringing it from the platform it finds itself to another position, on another translating platform, in the exit rooms or in the park places, as well as it is able to transfer the vehicle by bringing it from another place, on different translating platforms, in the entering rooms or in the park places, for positioning it on the platform onto which it finds itself. The cyclic movement is always of a back and forth type, in the sense that it moves from its platform up to another position for taking or leaving a vehicle for then coming back to the platform with or without the vehicle.
The following documents describe some known automatic mechanic parking systems: U.S. Pat. No. 4,968,208, KR 100696296, EP 1373666, KR100622553.
The applicant has observed that the known carriages, generally, do not realize the centering, taking and raising of the wheels of the car with a single device, thereby resulting complex and expensive to produce.
The document DE 198 42 084 (Stolzer) shows a transferring carriage comprising a frame, means of handling of said carriage and some devices for taking, raising and centering the wheels of a vehicle, wherein the respective movements are realized in different times and with a plurality of devices. In particular, while the taking and the raising of the wheels of the vehicle are realized by the transversal motion of the slides (26) and rotatory of the grippers (28) (29), the centering of the wheels takes place subsequently by means of an alignment of a central support (30) with respect to the longitudinal axis of the transferring carriage. This causes a dilation of the times of centering vehicle and necessitates of a plurality of different actuators.
Furthermore, document DE 198 42 084 shows a transferring carriage (20) suitable for sliding in a trench (18) existing between the supporting wedges (11) of the wheels of the vehicle. The devices for the taking and the raising of the wheels of the vehicle are positioned over the frame (21) of the carriage (20) for avoiding colliding, during their transversal motion, with said frame (21). From this derives a complexity and size of the transferring carriage shown in the aforementioned document due to which this last could not pass under the vehicle if said trench was not present. Consequently, its use requires realizing particular building constructions.
Furthermore, the applicant has noticed that the carriages for known mechanical parking systems do not allow centering, taking and raising the wheels of the car with a single movement that is continuous and composed by means of a single device.
The applicant has, furthermore, noticed that the carriages for known systems of mechanic parking do not allow to reduce satisfactorily the volume that is required for storing vehicles in the automatic mechanic parking systems.
According to the present invention, it is therefore realized a transferring carriage of vehicles for automatic mechanic parking systems comprising:
The applicant considers that not only the width necessary to the recovery of a vehicle is minimized by the automatic centering, but also the height that is necessary to the recovery of the vehicle is minimized thanks to the low thickness of the carriage according to the invention. The carriage according to the present invention can be, in fact, inserted below the vehicle without raising this last with respect to the sliding plane of the carriage itself. Another advantage is constituted by the simplicity of the carriage that by performing the centering, taking and raising of the wheels with a single devices, results lights and economic.
In the context of the present invention:

Furthermore, said method comprises a step of transmission of a stopping signal to a data processing unit supervising said electronic commands of motion of said couple of carriages; said stopping signal coming from position sensing means and causing the automatic activation of the electronic command of activation of said movable supports.
Advantageously, finally, said movable supports push said counterposed centering devices in a symmetrical way.
Further features and advantages of the invention will be clearer from the detailed description of some preferred and not exclusive embodiments of a new transferring carriage of vehicles for systems of automatic mechanic parking according to the present invention.
Said description will be hereinafter exposed referring to attached drawings, provided only for exemplificative and therefore non-limiting extent, wherein:
Referring to
Referring to the embodiment shown in the figures the carriage is constituted by a frame 1 provided with supporting free wheels 2 and driving 3 suitable for sliding on a planar surface a surface 4, like the upper surface of a platform of vertical translation and/or horizontal translation of the car parking place.
The free wheels 2 and driving 3 sustain the frame 1 that preferably presents two crossbeams 5 jointed by a central linking 6.
On the two crossbeams 5 are fixed two wheels 7 that drive the transferring carriage in its translation motion.
Preferably, the wheels 7 slide in a rectilinear channel 8 which is fixed to the planar surface 4 of the position of parking.
Preferably, the driving wheels 7 are elastically fixed to the crossbeams 5 by means of angular springs 9. The frame 1 is moved from a first geared motor 10 that through the pinions 11 and the shaft 12 transmits the motion to the driving wheels 3.
A centering, taking and raising device 13 of two wheels of an axle of the vehicle is housed on the frame 1. On the frame 1, the devices of centering 13 are arranged two by two opposed one with respect to the other.
Referring to embodiment shown in the figures, said device 13 of centering, taking or keeping and raising is composed by two movable supports 14 and by two couples of clamp elements 17, a couple for each movable support 14.
Each movable support 14 is preferably U shaped and comprises two tines 34 externally arranged with respect to a crossbeam 35, each prong 34 can slide in a crossbeam 5 of the frame 1.
The tines 34 of each movable support 14, can transversally slide into the crossbeams 5 by means roller wheels 15 which are guided on particular notches obtained in the crossbeams 5.
The movable supports 14 can translate between a resting closed position, shown in
More in detail, the two movable supports 14 are opposed with respect to a longitudinal axis X-X of the carriage 100 and can translate with respect to the longitudinal axis of the carriage X-X between a resting closed position, shown in
The open position is not a fixed position that depends by the structure of the device 13, but a position which changes each time, and being determined by the internal transversal distance between the tyres of the of the wheels of an axle of the vehicle to be transported.
The transversal distance inside the tyres of the wheels of an axle of the vehicle to be transported can be measured as the distance in the transversal distance between the two facing surfaces of the two wheels of an axle of the vehicle.
In other words, it changes according of the vehicle to be transported. For performing the centering of the vehicle, each time said open position is determined in such a way that once the vehicle is centered, the longitudinal axis X-X of the carriage 100 coincides with the longitudinal axis of the vehicle to be transported.
Each of the two movable supports 14 supports, in correspondence to one end a couple of clamp elements 17, each clamp element 17 can rotate of about 90° around a pin 18 which is fixed to the movable supports 14.
Each clamp element 17 being constrained to the pin 18 by means of bearings 19.
Always referring to the embodiment shown in the figures, it can be seen as the clamp element 17 is constituted by an arm 21 and by a lip 20 that, when the clamp element 17 is in the open position, slightly protrudes transversally towards outside of the carriage 100.
The lip 20 is associated to the arm 21 and is shaped so as to, when it is pressed against the tyre of a wheel 32 of the vehicle, tends to make the arm 21 rotate and consequently the clamp element 17 itself, from the open position shown with a dashed line in
Preferably, the arm 21 houses of the free rollers 22 arranged on an inclined plane in such a way to force the wheel 32 of the vehicle, that is grasped simultaneously by a couple of clamp elements 17, to raise.
For that purpose, the inclined planes of two clamp elements 17 of the same couple are counterinclined, when the arms 21 of the same couple of clamp elements 17 are in closure position.
The device 13 of centering, raising and keeping of the wheel 32 of a vehicle is capable of performing the raising and the rigid keeping of the two wheels 32 of an axle of the vehicle by means of a single transversal movement towards outside of the carriage of the movable supports 14 and of the couples of clamp elements 17 integral therewith.
In such a way, the frame 1 always rests axially oriented along the longitudinal axis X-X of the carriage 100. This advantageously allows to use the present invention in closed spaces like the modern underground car parks, wherein the carriages are made sliding on guiding rails and for which saving the lateral space necessary for letting the carriages pass is of a fundamental importance. The carriage 100 enjoys greater compactness also in height with respect to the solutions that were protected in the known art, also because the complex and unique motion which is operated by the device 13 of centering, raising and keeping of the wheel rests fixed on a same horizontal plane, fundamentally coinciding with the one of the frame (1) of carriage, and does not change height. The carriage 100 furthermore does not necessitate of a trench, passing under the vehicle by laying on the road plane or the pavement.
In this extent, the transversal motion of the U-shaped movable supports 14 is performed by means of a second geared motor 23 and by the pinions 24 thereof, which make rotate two worm screws 25.
Advantageously, therefore, only two geared motors are present, of which a first geared motor 10—is devoted to translate longitudinally the carriage 100 along the longitudinal axis X-X, while the second-second geared motor 23—is entirely devoted to control of the transversal motion of the movable supports 14.
The geared motors are electrically controlled by a data processing unit that advantageously is configured for driving in sequence first the first geared motor 10 for the positioning in correspondence of the wheels of the vehicle and subsequently for driving the second geared motor 23 for the transversal motion of the movable supports 14.
Referring to the embodiment shown in figure, it can be seen that—of the two worm screws 25—one has right-handed threading, while the other has left-handed threading.
The inverse rotation of the two worm screws 25 moves, preferably symmetrically, two pushing anchors 26 towards the outside or towards the inside of the carriage 100.
Preferably, each pushing anchor 26 is constituted by a cross-head nut 27 and by a quill with crossed crossbeam 28 at whose ends are fixed pins 29 onto which two pushing rod 30 are hinged.
The two pushing rods 30 are hinged at the opposite end of the pins 31 of each couple of clamp elements 17.
The pushing anchors 26 axially move towards inside or outside of the carriage 100 the movable supports 14 and consequently the couples of clamp elements 17 integral therewith.
Moving transversally towards outside, the movable supports 14 bring the lips 20 to stop against lo tyre of the wheel of the vehicle 32 and when the lips 20 axially push towards outside the tyre of the wheel of the vehicle 32 by triggering the rotation of the clamp elements 17 of each couple and consequently the taking and the raising of the wheel of the vehicle 32.
When the user conducts the vehicle into the entering room for the automatic parking, he leaves the vehicle itself in an area which is specifically delimited. The position of the vehicle axles can be detected using known devices like load cells, photocells, photoelectric cells barriers, laser scanners, cameras or others. Since the carriage 100 according to the present invention can raise two wheels 32 of an axle, the operation of transferring of a vehicle shall be realized by using two carriages 100 according the present invention, arranged in sequence in the longitudinal direction and, eventually, specifically connected each other.
In a first step, each carriage 100 will be positioned, by means of a control of the position and of motion realized with known methods, in such a way to have the own transversal axis coinciding in the neighborhood of the axle of a couple of wheels 32 of the vehicle.
The position of the two wheels 32 of the vehicle, being normally the longitudinal axis of this last not coinciding with the longitudinal axis of the carriage 100, will be such that, as shown in
In the
In detail, in
At this point, through the symmetrical pushing towards outside of the two devices 13, the operation of centering, raising and keeping of the wheels is started.
In a second and subsequent phase, one of the two devices 13 of centering, raising and keeping encounters first a wheel 32 (
Not being able to move further the second wheel 32 towards outside, being the transversal internal distance among the wheels 32 fixed, and consequently not being able to move neither the first wheel 32, the devices 13 of centering, raising and keeping actuate, in the continuity of motion of the pushing anchors 26, the rotation movement of the clamp elements 17 of the two couples.
In particular, the rotation movement of the clamp elements 17 of each couple is triggered by the reaction force exerted by the wheels 32 on the lips 20.
Said reaction force, making the clamp elements 17 slightly rotate around the pins 18, provides that the axis of the pushing rods 30 instead of passing by the axis of the pin 18, around which the clamp elements 17 rotate, moves slightly so as to create a couple that triggers a rotation movement of the clamp elements 17 and that increases always more with the rotatory movement of these last up to obtaining the raising of the wheels 32, as shown in
The
