"ELECTRICAL DEVICE FOR MOVING VEHICLE STEP"

It is the subject of this Utility Model Patent application for an unpublished "VEHICLE MOVING ELECTRIC DEVICE" especially a device better represented by a simple constructive electric winch coupled to the vehicle chassis in a concentric line with the spare wheel, comprising: electric gearmotor, wire rope and safety hook plate for steppe locking when not in use, can be operated by internal switch or remote control without the need for greater efforts to place and remove the steppe.

The innovative device has as its field of application vehicles with

spare tire under the chassis as an example: cars, trucks, trucks, among others.

On vehicles with a spare tire under the chassis, there is an ergonomic drawback when changing a tire

One has to make an effort beyond the physiologically acceptable limit which is about 10% of body mass.

In these types of steppes it is imperative to use tools and / or

Secret keys that trigger a ratchet mechanism that moves the steppe with it.

Some of these mechanisms are accessed through holes

apparent and unprotected easily accessible by simply inserting the tool to release the spare tire for subtraction.

Others work in the same way as above, but after stepping down they have a plus, ie a secret key to release it sometimes having to lie under the vehicle. This does not solve the problem of theft altogether, as a malicious person even without the secret key could cut the wire rope.

In a way to solve the theft problem many users use

additional chains and padlocks likewise capable of being cut and / or broken.

The constructive simplicity in the system comprising the conventional spare tire holder and the ease of circumvention has drawn the attention of miscreants who place the product stolen in the parallel / illegal market.

Therefore, the conventional system that releases the spare tire from the chassis of the vehicle by simply pushing a device offers no safety,

encouraging, as already commented, the theft of steppes which above all is more profitable for the thief than other items of the vehicle.

Given this situation, it was motivated to develop a

electrical device for moving the spare tire that could at the same time,

easy to handle, simple to construct, and efficient to place and remove the

spare part of the vehicle chassis and prevent theft by means of the

safety, which remains absolutely static due to the gearmotor brake,

in accordance with the focus of this privilege request, has gained space in the

market, which is constantly seeking practical, contemporary and efficient procedures.

the present state of the art anticipates some patent documents dealing with the subject matter, such as MU8802453-9, called ■ CONSTRUCTIVE DOOR ARRANGEMENT “more specifically a steppe door consisting of fixed sleepers to the valve - operated vehicle chassis, pneumatic actuator, airbag, pneumatic pump, roll - over shim and rollers that promote opening and

door step closure which also has the function of locking and unlocking using pin and grind assembly.

The device analyzed above has a complex constructivity, because its operation requires a pneumatic medium such as a compressor.

air vehicles in cargo vehicles, which prohibits their use in air vehicles.

ride

Aware of the state of the art, its shortcomings and limitations, the inventor, after studies and research, has created the "ELECTRICAL VEHICLE DRIVING DEVICE" in question, which, in general, is especially a device of simple constructivity. comprised of electric gearmotor, pulley, wire rope and safety hook plate which are mounted in a machinery box under the vehicle chassis. This device not only ensures safety but also facilitates the removal operation as well as the

replacement of the changed tire and / or spare tire after your concert, with the option of

remote drive.

The immobility of the spare tire when raised, ie not in use, is due to the fact that the gearmotor with the retracted wire rope acts as a brake avoiding

any possibility of forced movement of the steppe for further cutting of the

steel cable.

In normal operation, after the steppe has been lowered, the wire rope is removed from the anchor plate by pressing a hook-type pin that undeniably engages an eye in the inner face of said plate.

In short, the claimed innovation has as its most important advantages

> Simple constructivity - you can use your own electric or vehicle battery;

> Prevents theft of the gearmotor brake steppe;

> No need to use tools, cranks and others to remove and insert the spare tire, so no need to carry them in vehicles;

> Easy handling;

> Provides much comfort - ergonomically suitable;

> Greater agility in steppe replacement;

> Possibility to be used with a protective casing that covers the spare tire.

The following explains the model with reference to the accompanying drawings, in which they are shown by way of illustration and not limitation:

VEHICLE ", which is the subject of this Utility Model Patent Application, relates in particular to a device (1) composed of a machine housing (2) fixed under the chassis (3) of the vehicle, which comprises an electric gearmotor (4) with central pulley (5) and wire rope (6) attached by safety hook (7) to the anchor plate (8) overlapping the steppe (E).

More particularly, the innovative device (1) consists of a machine housing (2) duly fixed under the chassis (3) of the vehicle, which inside contains a sturdy and organized electric motor (3) which moves, down and up, a central sheave (4) from which a wire rope (5) is provided with at its end a safety hook (6) with retractable side (7) that can be fitted to the eye (8) located on the inner side. of the anchor plate (9) overlying the bore (10) of the wheel (11) of the steppe (E). When the steppe (E) is fully raised, ie in a transport position, the anchor plate (9), larger than the hole (10) of the wheel (11), stays close to it due to the tensioning and locking of the wire rope (5) as a result of the gearmotor brake action (3), thus avoiding any possibility of moving the spare tire (E) in order to lower it forcibly.

In one constructive option the device (1) may be equipped with its own battery (12) or in another option fully utilize the electrical system of the

vehicle.

The device can be operated by an internal electric switch or by remote control.

Lastly, the device (1) may be equipped with a protective cover (13) of the steppe (E), in which case the anchor plate (8) is superposed to said envelope.

Therefore, the present utility model patent application is novel and inventive thanks to the possibility of electrically raising and lowering the spare tire in vehicles with emphasis on practicality and safety, which added the industrial application deserves the privilege of

patent.
