Abstract

Lifting device for automobiles, which being specially designed for the elevation of the same at the level of any of its wheels before a puncture or other similar event, is characterized because it is constituted by four jacks, preferably electric, hydraulic or pneumatic, integrated in the vehicle chassis itself in the vicinity of their respective wheels, said jacks being operable independently through a set of double push-buttons, namely a double push-button for each jack, determining the elongation and shortening thereof.

Description

Lifting device for cars.

Object of the invention

The present invention relates to a device that has been specially designed to achieve the auto-lift of a car, when necessary to replace some of its wheels on it, due to a flat tire or to any other cause.

The object of the invention is to integrate into the own vehicle said lifting means, and that these are of Extremely easy and comfortable drive.

Background of the invention

As is known, for the replacement of a wheel any of a motor vehicle is necessary, after a maneuver initial loosening of the corresponding screws, raise the corresponding area of the vehicle for the wheel to separate from the ground and can be extracted and replaced by another.

Regardless of the systems used in workshops to mobilize the vehicle when it comes to conducting cover changes, and for the specific problem of suffering a flat tire on the road or anywhere else where the user of the vehicle must be the one that proceeds to change the wheel, the car manufacturers supply with each of them a cat mechanical, that introducing it conveniently under the chassis of the vehicle, between it and the ground, allows the intended and necessary elevation.

While these cats meet satisfactorily with the function for which they have been planned, in practice Two problems arise that can become important:

-

Is relatively frequent for vehicle users to use their cat for other purposes and that with relative often do not place the cat again, after use, in the inside the vehicle, so that at the moment it arises the aforementioned problem, that is, for example, a road prick, no jack available to raise the vehicle, which can lead to long waiting periods up to get another motorist to stop and accept the waste of time which means waiting for the change of the wheel. In other cases the Cat absence is due to theft or other causes.

-

The jack actuation maneuver, especially in the phase of vehicle lift is difficult for people with certain physical characteristics, such as for elderly people, people with certain disabilities physical, etc.

Description of the invention

The device proposed by the invention resolves in a fully satisfactory way the problem previously exposed, in the two aspects commented.

To do this, more specifically and in order to solve the first problem, the availability of the cat, has provided that said device materializes in four jacks, one for each wheel of the vehicle, fixedly mounted on the chassis of the latter, so that the availability of cat before any problem on any of the wheels of the vehicle remains insured

These jacks can be manually operated, with the contest of an appropriate lever, but to solve the second of the aforementioned problems it is expected that said cats are electrically or hydraulically operable, with the collaboration of a single appropriate keypad or multiple control, which can stand on the dashboard of the vehicle or anywhere else That is deemed convenient.

In this way a simple group of four double pushbuttons allows the vehicle to be raised and lowered at will in correspondence with any one of its four wheels.

Obviously the placement of these cats in the vehicle context will be the most suitable, specifically where the characteristics of the vehicle allow its implementation in withdrawal or inoperative situation, without affecting others vehicle elements, such as immediately ahead of its rear wheels and immediately behind its wheels front.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows a representation lower floor schematic of the lifting device than the invention proposes properly implanted on a vehicle car.

Figure 2.- Sample, also according to a schematic representation, now in elevation, the whole of the previous figure at the level of one of the lifting jacks.

Preferred Embodiment of the Invention

In view of the figures outlined, and in special figure 1, can be seen as the device that The proposed invention is embodied in four cats (1), conveniently fixed to the chassis (2) of the vehicle in correspondence with its four wheels (3), cats that in the example of performance chosen are hydraulic, so each of them  is connected, through the corresponding conduction (4), with a hydraulic compressor (5) located in any available space of the vehicle and fed at the expense of the latter's engine.

In this specific case the compressor will be put into operation at the discretion of the driver of the vehicle acting on the corresponding switch, while the double push buttons previously mentioned will in turn move solenoid valves fluid to each of the cats (1), in the sense of elevation or descent of them.

Figure 2 shows the clarity of the arrangement of each of the cats (1), materialized in a hydraulic or pneumatic cylinder that corresponds to the own reference (1), whose stem (6) remains normally retracted, at the level of the wheel hub, so that it does not hinder the normal vehicle circulation, but which is likely to move telescopically down to the position shown in the cited figure 2, in which the wheel (3) is raised from the ground and It can be disassembled and replaced by another.

As previously said cats (1) they can be electrically operated, in which case each of they will be assisted by an equally electric motor, which through of a proper transmission supplies the movement to the cats, in one way or another, at the expense of the corresponding double button.

In order to ensure the stability of the vehicle during the wheel change maneuver, it is planned that the said rod (6) defined in the cat (1) is auctioned off by its free end in a rubber shoe (7) or other material anti-slip.

Claims (4)

1. Lifting device for cars, which being specially designed for lifting them at the level of any of its wheels before a puncture or other similar eventuality, is characterized in that it is constituted by four jacks, preferably electric, hydraulic or pneumatic, integrated in the vehicle's own chassis in the vicinity of their respective wheels, said jacks being independently operable through a set of double push-buttons, specifically a double push-button for each jack, determining the lengthening and shortening thereof. 2. Lifting device for cars, according to claim 1, characterized in that when the jacks are hydraulic or pneumatic, they are connected through back and forth conduits with a compressor in turn hydraulic or pneumatic, fed at the expense of the vehicle's engine, being established in said conduits solenoid valves governed from the aforementioned double push button panel. 3. Lifting device for cars, according to claim 1, characterized in that when the jacks are electric, each of them incorporates an electric motor, directly operable in one or the other direction by means of the corresponding double button. 4. Lifting device for cars, according to claim 1, characterized in that optionally the jacks can be manually operated, by means of the corresponding levers.
