Definitions

the present invention can be situated in the technical sector of bodywork and mechanical workshop equipment and relates to a lifting device for vehicles.
the lifting device according to the present invention can be of the scissor type, and/or with two columns and/or or a type with an air spring.
These devices commonly called lifting bridges or simply car lifts, consist of a load-bearing structure that can be anchored to the ground (or over a pit for total or partial embedding of said lift in the floor) and a movable structure, which is fixed to the load-bearing structure, and designed to undergo a translational movement in a vertical direction between two end positions.
the movable structure is designed to be raised/lowered between a lower position, in which it is substantially close to the ground (or flush with the floor in the embedded versions), and an upper position in which it reaches a pre-determined height from the ground (generally less than 2.5 meters).
a plurality of arms is also provided which are anchored to the movable structure and provided with respective terminal elements, commonly called pads, whose upper surface is intended to come into contact with the bottom of the vehicle to be lifted.
the pads constitute the only part of the movable structure that interacts with the vehicle when it is lifted upwards or during its downward descent.
the weight of the vehicle therefore, is borne entirely by the movable structure and the load-bearing structure of the device through the pads and the arms.
the pads (and thus the corresponding arms supporting that support the pads) are equal in number and equally distributed between the right side and the left side of the vehicle to promote a uniform weight distribution of the vehicle over the structure.
the arms that support the pads are hinged to the movable structure to allow their selective rotation by an operator who is preparing to lift the vehicle.
the arms When the lifting device is not in operation, the arms can be placed in a rest position in which they are in contact with (or in proximity to) the movable structure to reduce the overall dimensions of the device.
the operator Before lifting the vehicle, the operator, manually or through an automatic actuation system, will rotate the individual arms up to a final position in which the pad comes into contact with the bottom of the vehicle (usually at the points predefined by the vehicle manufacturer).
This rotation can be caused by a chance interaction of the arms with people and/or with moving objects present in the installation environment of the lifting device.
a chance movement of the arms can be the result of contact between the same and the body of one or more operators who are preparing to work on the bottom of the vehicle, or be caused by an interaction with moving elements such as trolleys, cables, compressed air conducts, etc.
a movement of the arms occurring just prior to the interaction between the pad and the vehicle can be dangerous for the latter and for the operators located in the vicinity of the device.
the pad could come into contact with fragile parts of the bottom or with components of the vehicle not suitable for supporting its weight (portions of the body, components of various types, tube, etc.). Furthermore, the degree of freedom that the arms have during lifting could give rise to an unstable contact between the bottom of the vehicle and the pad.
the present invention intends to overcome the aforementioned technical drawbacks by providing a lifting device for vehicles which is particularly safe and reliable.
the main object of the present invention is to provide a lifting device for vehicles capable of keeping the position of the vehicle stable during its raising and lowering.
a further object of the present invention is to provide a lifting device for vehicles that is simple to manufacture and particularly flexible in terms of its use.
Another object of the present invention is to provide a lifting device for vehicles which exhibits high durability over time and requires reduced maintenance.
the object of the present invention is to provide lifting device for vehicles the configuration of which satisfies all the safety regulations stipulated in various countries with reference to the sector of bodywork or vehicle assistance.
the present invention relates to a lifting device for vehicles which will be indicated in the following description by the reference number 1 .
the device 1 can be used to lift road vehicles with different sizes and functions such as, for example, cars, vans, trucks, buses etc.
Figures 1 to 10 show a preferred embodiment of the lifting device 1 according to the present invention which comprises suitable adaptations and dimensional modifications depending on the size of the vehicle to be raised/lowered (car, truck, bus, caravan, etc.).
the lifting device 1 comprises a stationary structure 2 intended to be placed on the ground S .
the stationary structure 2 can consist of a support base 3 which has a substantially rectangular shape and is designed to be stably anchored to the ground S by means of a plurality of locking screws (not shown in the figures).
the support base 3 can be embedded inside a special recess made in the floor of the installation environment.
a movable structure 4 operatively connected to the stationary structure 2 and operation means 5 designed to promote the selective and controlled lifting or lowering of the movable structure 4 with respect to the stationary structure 2 between two predetermined limit positions.
the movable structure 4 can comprise a platform 6 made of a metallic material and having an upper surface 7 which is substantially flat and horizontal.
the platform 6 is connected to the support base 3 by means of two pairs of parallel side members 8 , 9 having a lower end 10, 10 ' fixed or hinged to the base 3 and an upper end 11 hinged to the platform 6 .
the lower end of a pair of side members 8 will be hinged to the base 3 in a fixed position while the lower end 10 of the other pair of side members 9 is anchored to the base 3 to be able to translate along a substantially horizontal direction X .
each side member is arranged on opposite sides with respect to a vertical centerline plane passing through the platform 6 and indicated in the figures by the symbol ⁇ .
the pairs of side members 8 , 9 are joined together via a horizontal crosspiece 12 arranged in a position substantially equidistant from the ends 10, 10' and in correspondence with the centerline plane ⁇ , as is better visible in Figures 2 and 3 .
the operation means 5 comprises a piston 13 provided with a movable rod 14 whose head 15 is hinged to a bracket 16 which is in turn connected to the crosspiece 12 in a rotatable manner.
the progressive extension (or return) of the rod 14 of the piston 13 allows the counterclockwise (or clockwise) semi-rotation of the bracket 16 by promoting the translational movement of the crosspiece 12 upwards (or downwards) along the centerline plane ⁇ .
the cylinder 17 of the piston 13 is constrained to the base 3 and during its operation the lower end 10 ' of the side members 9 can translate towards the inside of the base 3 (in the case of a forward movement of the rod 14 ) or towards the outside of the base 3 (in the case of a return movement of the rod 14 ).
pairs of side members 8, 9 are free to move between a position in which they are substantially horizontal and parallel to each other (complete lowering of the movable structure, maximum retraction of the rod 14 ) to a position in which they are arranged according to a symmetrical "X" shape with respect to the centerline plane (complete raising of the movable structure, maximum extension of the rod 14 ).
the piston 13 can be of the oleodynamic or pneumatic type and can be replaced by any linear actuator of a different nature (i.e., electrical) adapted to promote the translational and bidirectional movement of a thrust element which can be anchored to the crosspiece 12 .
the platform 6 translates vertically between a lower limit position, in which it is substantially placed in proximity to the support base 3 , and an upper limit position in which it is placed at a predetermined height from the ground S .
the platform in the upper limit position can reach a height h that does not exceed two meters.
the lifting device 1 further comprises a plurality of arms 18 provided with one end 19 hinged to the movable structure 4 and a free opposite end 20 to which is associated a pad 21 designed to come into contact with the bottom of the vehicle to be lifted.
the device 1 typically comprises an even number of arms 18 uniformly arranged along the side edges 22 , 23 of the platform 6 .
the use four arms 18 distributed in pairs along the respective edges 22, 23 of the platform 6 is envisaged.
Each arm 18 is consequently free to selectively rotate around a respective substantially vertical hinge axis Y between an inactive position and an active position.
the arms 18 can be substantially straight and, in the inactive position (not visible in the figures), they can be collected in proximity of the side edges 22 , 23 of the platform 6 to reduce the overall dimensions of the device 1 .
the angle ⁇ can be the same for all arms 18 or can be different for one or more of them.
the active position can be the same for all the arms 18 or can vary for one or more arms, according to the requirements.
the rotation of the arms 18 between the two inactive/active positions can be performed manually by an operator or can be carried out in an automatic or semiautomatic manner through the use of suitable actuators.
the configuration of the invention illustrated in the figures refers to this second case, in which four small pistons 24 having the bottom of the cylinder hinged to the platform and the head 25 of the rod hinged to the respective arm 18 are provided.
the pads 21 can be fixed to the arms 18 in a removable manner and their vertical position with respect to the latter can be manually adjusted by the operator.
the upper surface 26 of the pads 21 is intended to come into contact with the bottom of the vehicle and for this reason is located at a height from the ground h' slightly higher than the height h of the platform 6 , generally higher by a few centimetres.
the vehicle interacts exclusively with the pads 21 while the platform 6 is designed to never come into contact with the bottom or with other parts of the means of transport, which is raised with respect to the ground S .
the pads 21 are generally made of a semi-rigid material suitable for supporting the weight of the vehicle, generally rubber or other similar polymeric materials.
the pad 21 can be anchored directly to the arm 18 or can be associated with the latter in a removable manner, as better illustrated in Figures 2 , 4 , 5 and 8 .
the pad 21 is integral with a section of profiled tube 27 (generally having a rectangular cross-section) having an internal cavity 28 inside which the end portion of the arm 18 can be inserted in a sliding manner.
the section of tube 27 can be fixed to the arm 18 by means of rapid connection means (for example the insertion of a pin into suitable holes formed on the arm and on the tube) or with other fastening elements known per se and not described in the following description.
locking means 29 designed to selectively and automatically lock the plurality of arms 18 when the latter are in the active position are provided.
the presence of the locking means 29 prevents the arms from rotating inadvertently and/or suddenly from their active position during their interaction with the vehicle floor, or during the raising/lowering of the vehicle itself.
locking means used in the present description is intended to refer to means of reversible type, which can be selectively operated to effect both the rotational locking of one or more arms in an active position, as well as the unlocking of the same in order to allow them to rotate from the active position to the inactive position.
the locking means 29 can be configured to selectively lock one or more arms 18 in the active position, for example two out of four arms.
the locking means 29 can be configured to selectively lock all arms 18 in the active position.
the locking means 29 can promote the locking of all arms 18 in the active position substantially in simultaneous, i.e., at the same moment in time.
the locking means 29 can be configured to promote the locking of the arms 18 at different moments in time, for example one after the other or in accordance with a precise locking sequence.
the locking means 29 can comprise a plurality of first locking elements 30 rigidly connected to the hinged end 19 of a respective arm 18 .
the first locking elements 30 can thus be designed to rotate around the hinge axis Y of the corresponding arm 18 when a movement between the active position and the inactive position (or vice versa) is conveyed to the arm 18 .
the first locking elements 30 are positioned on the outer surface 31 of the platform, above the respective arm 18 .
first locking elements 30 can be manufactured with a plate of reduced thickness and are integral with the hinge pin 32 passing through the end 19 of the respective arm 18 .
the locking means 30 comprise a plurality of second locking elements 33 placed in proximity to the first locking elements 30 .
Said second locking means 33 are better visible in particular in Figures 4 - 6 .
Each first locking element 30 can be associated with a corresponding second locking element 33 and the latter can be integral with the movable structure 4 .
the second locking elements are anchored to the upper surface 31 of the platform 6.
the second locking element 33 can be obtained from a section of metal profile with a reduced thickness (flat profile).
each second locking element 33 can have an elongated shape that extends along a respective direction of extension W substantially horizontal and orthogonal to the hinge axis Y of the respective arm 18 .
the second locking element 33 can be located in proximity of the side edges 22, 23 of the platform 6 and its extension direction W can be substantially parallel to said edge.
each pair of second locking elements 33 is arranged to define a single direction W along which both elements 33 extend.
first locking elements 30 and the second locking elements 33 have respective end edges 34 , 35 arranged in a mutually facing position.
Said edges 34 , 35 are provided with respective shaped portions 36 , 37 having at least one section with a complementary shape to each other.
the complementary shape of the shaped portions 36, 37 therefore allows the edges 34, 35 to mutually commit to each other when they come into contact.
the first locking element 30 has a substantially semicircular edge facing the second locking element 33 .
a toothing 38 (clearly visible in Figure 6 ), the extension of which is chosen so that the teeth are always facing the second locking element 33 , is formed at a portion 36 of said edge.
the toothing 38 performed on the edge portion 36 of the first locking element 30 always faces the second locking element 33 , regardless of the rotation angle ⁇ chosen to determine the active position of the corresponding arm 18 .
the second locking element 33 has an edge portion 37 which is also semicircular and faces the toothed edge portion 36 of the first locking element 30 .
the semicircular edge portion 37 of the second locking element 33 has a radius substantially equal to that of the toothed semicircular edge portion 36 of the first locking element 30 .
the edge portion 37 of the second locking element 33 likewise includes a toothing 33 the pitch and the shape of the teeth of which is substantially the same as that chosen for the toothing 38 formed on the edge portion 36 of the first connecting element 30 .
first locking element 30 and/or the second locking element 33 are movable with respect to each other between a first position and a second position.
edge portions 36 , 37 associated with the first locking element 30 and the second locking element 33 are spaced apart and disengaged from each other.
the first locking element 30 can freely rotate around its own hinge axis Y when a rotation is convey to the respective arm 18 .
the edge portions 36, 37 are mutually in contact so as to be mutually engaged and promote the locking of the first locking element 30 (and thus of the respective arm) with respect to the second locking element 33 .
the locking means 29 illustrated in Figures 1 to 9 exhibits locking elements 30, 33 with the corresponding edge portions 36, 37 in the second position.
the first locking element 30 although free to rotate with respect to its own hinge axis Y , is constrained with respect to any other movement, including a translation towards the second locking element 33.
the first locking element 30 is fixed with respect to the second locking element 33 inasmuch as it cannot approach or move away from the latter.
the second locking element 33 is mounted on the platform 6 in to be free to perform a selective and controlled translation along its extension direction W .
the range of this translation will be such to allow the edge portion 37 to approach/move away from the edge portion 36 of the first locking element 30 so as to move between the first position of disengagement (in which the toothing 38, 39 formed on both elements 30, 33 are distal to each other) and the second position of engagement (in which the meshing of the toothing 38, 39 formed on both elements 30, 33 occurs).
the second locking element 33 includes an elongated seat 40 inside which a fixed pin 41 integral with the platform 6 is inserted.
the pin 41 slides inside the seat 40 to guide the translational movement of the element between the first and second position.
the locking means 29 further comprise at least one actuator 42 suited to selectively move the edge portion 37 of the second locking element 33 between the first position and the second position (and vice versa).
two piston type actuators 42 are provided, each of which has a cylinder 43 connected to the platform 6 and ends (respectively constituted by the head of the rod 44 and the bottom 45) connected to the pair of second locking elements 33 arranged along the same side of the platform 6 .
the head of the rod 44 and the bottom 45 of the actuators are free to translate along a direction substantially parallel to the direction of extension W of the second locking element 33 .
the head of the rod 44 and the bottom 45 are arranged on opposite sides with respect to the centerline plane ⁇ .
ends 44, 45 of the piston 42 are connected to the end portions of the second locking elements 33 by means of a screw 46 passing through an elongated seat 47 suitably obtained in the platform 6 (clearly visible in Figure 9 ).
the shaped edge 37 of the second locking elements 33 will move away from the shaped edge 36 of the first locking elements 30 , to the position of disengagement.
a single actuator 42 can promote the movement of a pair of second locking elements 33 arranged on the same side of the platform 6 .
the device 1 it is possible to provide for the installation of a single actuator 42 designed to control the movement of all the second locking elements 33 or for the use of a plurality of actuators 42 that can be operated independently, each being associable with a single connecting element 33.
the actuators 42 can be operated simultaneously so as to promote the simultaneous movement of the edge portion 37 of the second locking elements 33 into the second position (corresponding to the mutual engagement of the toothing 38, 39 ).
the actuators 42 can be operated at different times to promote the selective engagement 36, 37 of the edges of the locking elements 30, 33 at staggered or different times.
Figure 10 shows a different configuration of the elements 30, 33 which constitute the locking means 29 .
edge portions 36, 37 of the respective locking elements 30, 33 do not have a toothing, but a particular "coupling" shape substantially designed to replicate that of a "male-female” type.
the first locking element 30 is in fact provided with a plurality of recesses 48 arranged along radial directrices R which extend starting from the centre of the element (which is placed in correspondence with the hinge axis Y of the respective arm 18) .
Each radial directrix R is designed to define a certain active position of the arm 18, i.e., the angular position of the directrix R defines a corresponding angle of rotation ⁇ .
the active positions of the arm 18 are discrete inasmuch as they refer to a predetermined angle of rotation ⁇ at which a corresponding recess 48 has been formed on the first locking element 30.
the second locking elements 33 have an elongated edge portion 37 with a shape substantially counter-shaped the recesses 48 formed on the first locking element 30.
the recesses 48 and the elongated edge portion 37 are spaced apart to allow the rotation of the arm 18 around the hinge axis Y; however in the second position the elongated edge portion 37 of the second connecting element 33 is inserted inside a corresponding recess 48 formed on the edge 37 of the first connecting element 30.
