Abstract

The present invention refers to the field of lifts for servicing small vehicles, such as for example motorbikes and particularly quads.

The lift (1) comprises at least two structures (2, 2') each comprising: a flat element (9), on which a vehicle can be positioned, supported by a lifting unit (3) located below the flat element (9); a frame (6) located below the lifting unit (3), acting as a base for the structure (2, 2'); said frame (6) and said flat element (9) can be parallely located one to the other with respect to the centerline of the flat element (9).

Said structures (2, 2') are characterized by the fact that they can be reciprocally moved close or away by sliding means (11) integral with the frame (6) of each structure (2, 2') and engaging corresponding guiding tracks (16).

Description

FIELD OF THE INVENTION

The present invention refers to the field of the lifts for small vehicles such as for examples motorbikes and particularly quads.

STATE OF THE ART

As it is known, for servicing vehicles scissor-like lifts, pantograph-like lifts or lifts with four columns, with an hydraulic or pneumatic pump are used.
Said lifts are substantially formed by a single structure formed by:

a flat element, that is an horizontal surface, on which the vehicles are located by rise/descent ramps;
a lifting unit, centrally located below the flat element, comprising hydraulic or pneumatic cylinders and at least two pairs of levers wherein a stationary lever is articulated to another freely sliding lever;
a frame on which the lifting unit is fixed.

The flat element can be in one piece, or is formed by a plurality of parts.
As an example, patent EP1851160 , describes a scissor-like lift, comprising a single structure with a lifting unit centrally located below the flat element.
It is to be noted that the scissor-like arrangement is preferred when an operator wants to work at an height greater than the ones of the other kinds of lifts but with a decidedly smaller size.
Said flat element is movable and is provided with rise/descent ramps and with containment stops and can be divided by translating on suitable guides. It is to be observed that, as a function of the vehicle to be positioned, the flat element can take different arrangements, such as for example:

closed, for motorbikes;
divided in two parts for four wheels vehicles;
divided in three parts for three wheels vehicles. Unfortunately, the lifts of the prior art, since they comprise a single structure with a single central lifting unit, and therefore schematically just one support point, are unstable. In fact, once a four wheels vehicle, such as a quad, has been positioned, the cantilevered structure can be unstable during the rising and descending steps.

Moreover, it is to be noted that since these lifts have a lifting unit centrally located with respect to said single structure, the servicing operations of the central part below the positioned vehicle are more difficult and limited.

DISCLOSURE AND ADVANTAGES OF THE INVENTION

The object of the present invention consists of solving the above-mentioned problems by providing a further lift, such as a scissor-like lift, formed by at least two structures which in turn are each formed by a flat element, a lifting unit and a frame acting as a base. Sliding means adapted to slide the structures on guiding tracks are fixed to said frames.
A first advantage of the invention is due to the fact that, since the structures translate along the guiding tracks, it is possible to easily perform the servicing operations of four wheels vehicles because it is possible to stay centrally under them and not at the side, as it occurs with the car lifts.
Another advantage consists in the fact that said invention is more stable both during the servicing step and during the rise and descent steps of the flat element.
Said objects and advantages are all met by the lift for motorbikes and quads, object of the present invention, which is characterized by the attached claims.

BRIEF DESCRIPTION OF THE DRAWINGS

This and other characteristics will be better understood by the following description of a preferred embodiment shown in a non limiting exemplifying way in the attached drawings.

Figure 1 illustrates a perspective view of the device.

DESCRIPTION OF THE INVENTION

Particularly referring to figure, 1 generally indicates a lift, particularly a known scissor-type.
Said lift 1 comprises at least two structures 2, 2' each having a lifting unit 3, 3'.
Since said structures 2, 2' are completely identical, in the following, for the sake of simplicity, we will refer just to one of the two.
A structure 2 comprises:

a flat element 9, on which vehicles can be positioned, supported by:
a lifting unit 3 located below the flat element 9;
a frame 6, located below the lifting unit 3, acting as a base for the structure 2, 2'; said frame 6 and said flat element 9 are parallelly located one to the other with respect to the centerline of the flat element 9.

At least one of the two short sides of the flat element 9 is provided with a vehicle rise/descent ramp 10.
Said structures 2, 2' are characterized by the fact that they can be reciprocally moved closed or away by sliding means 11 integral to the frame 6 of each structure 2, 2' and engaging corresponding guiding tracks 16.
Said sliding means 11 can slide along guiding tracks 16 by friction, using runners, or by rolling by means of a plurality of wheels 14 mounted to one of plates 12 fixed by slots 13 to the short sides of the frame 6, as shown in the figure.
The lifting unit 3 is formed by:

at least two levers 4 articulated in a pin 5, one 4a of these pins can freely slide inside the frame 6, the other lever 4b is hinged to the bottom end of the frame 6 itself;
at least a cylinder 7, for example an hydraulic one, acting as a motion transmission member, fixed at one of its ends to the frame 6, and to the other end to the levers 4 by a sector 8.

An example of embodiment provides that the guiding tracks 16 are integral to a platform 17 making the lift 1 easily transportable and locatable.
The sliding means 11, and consequently the structures 2, 2', can be engaged/disengaged from the corresponding guiding tracks 16 by means of an engaging/disengaging system 15, comprising an hydraulic cylinder and a group of leverages.
Operatively, during a motorbike servicing, the structures 2, 2' have a closed arrangement, that is they are close one to the other, the flat elements 9, 9' being longitudinally adjacent.
Instead, when it is desired to position a four wheels vehicle, for example a quad, the structures 2, 2' translate along the guiding tracks 16 by the sliding means 11, and finally take an opened arrangement.
In the shown solution, in this position, by the engaging/disengaging system 15, the wheels 14 can be raised so that the frames 6, 6' directly abut the platform 17, stopping the structures 2, 2' in the desired position.
It is to be noted that the two cylinders 7, 7' are driven by a single driving unit and therefore, for example, by a known hydraulic system, which causes, by the adjustment of a service fluid flow rate, the raising of the stems and in turn of the structures 2, 2'.
