Abstract

Hook device for towing perfected and characterized because it is constituted by at least the following elements: (1). Body of the device, constituted by a cylindrical body, with two inner diameters, the outer one of smaller diameter, (2). Hook itself, consisting of a cylindrical piece in the shape of "L" and topped by a spherical thickness (8) that will be where the traction part of the trailer is adapted, (3). Internal thread, made inside the hook (2) and along the entire length of the horizontal part thereof, (4). Stop of the hook (2) constituted by a cylindrical thicknessing located at its opposite end to the spherical thicknessing (8), (5). Shank with thread, integral with the head of the shank (6), (7) electric motor. (Machine-translation by Google Translate, not legally binding)

Description

5 OBJECT OF THE INVENTION

The recommended invention relates to a perfected tow hook device for those that can be installed in motor vehicles that can be used as a point of support and traction for any type of trailer and a

Once its towing function has been fulfilled, it is hidden under the body of the motor vehicle in order to avoid the dangers of the existence of said hook protruding from the body for other vehicles, users, and pedestrians.

FIELD OF THE INVENTION

The field of the invention is that of manufacturers of accessories for motor vehicles.

BACKGROUND OF THE INVENTION

There is some background to the system described in this specification.

Some of them have been studied, almost all of them in a similar way because of the homologation requirements.

Likewise, the existence of some complicated concealment systems has been detected in special car body cubicles, but none of the antecedents offer such a simple and efficient arrangement.

30 as the one advocated by the invention.

On the part of the inventor there is no known priority that incorporates the provisions presented by the present invention, nor the advantages that such provision entails.

DESCRIPTION OF THE INVENTION

The recommended invention relates to a trailer hook device perfected from those that can be installed in motor vehicles that allow any type of trailer to be used as a support and traction point and, once its towing function has been fulfilled, is hidden under the body of the trailer. motor vehicle in order to avoid the dangers of the existence of said hook protruding from the body for other vehicles, users, and pedestrians and which is constituted by 1) .- body of the device, consisting of a body

10 cylindrical, with two inner diameters, the outer one of smaller diameter and the hook itself, constituted by a cylindrical piece in the form of "L" and finished off by a spherical thickening that will be where the traction part of the trailer is adapted.

15 Inside the hook (2) and along the entire length of the horizontal part of the hook there is a thread and at its end a stop of the hook constituted by a cylindrical thickening located at its opposite end to the spherical thickening.

20 The rest of the elements are constituted by a threaded rod, integral with the head which in turn is moved by an electric motor and said rod running through the inside of the solidarity hook with the thread there existing.

25 The operation is simple, once the hook has finished the towing work, the electric motor that rotates the rod head is activated, which, being integral with the threaded rod, causes the hook to move backwards until it stops the head and so that at this time, the hook that has been hidden by rotation is in a horizontal position, so that the

30 spherical thickening is always in a horizontal position so that it can be hidden under the vehicle body without disturbing at all

DESCRIPTION OF THE DRAWINGS

For a better understanding of the invention, a sheet of drawings is attached which shows the following

FIGURE 1.-Schematic view of the hook device in its two arrangements, in working position and collected.

FIGURE 2.-Schematic side view of the device in working position.

FIGURE 3.-Schematic side view of the device in the collected position.

And in these figures, with the same reference they are called identical elements, among which we distinguish:

(1) .- device body, (2) .- hook, (3) .- internal thread, (4) .- cap, (5) .- stem with thread, (6) .- stem head, (7) .- electric motor, (8) .- spherical thickening

PREFERRED EMBODIMENT OF THE INVENTION.

The recommended invention relates to a trailer hook device perfected from those that can be installed in motor vehicles that allow any type of trailer to be used as a support and traction point and once it has fulfilled its towing function it is hidden under the vehicle body car in order to avoid the dangers of the existence of said hook protruding from the body for other vehicles, users, and pedestrians and which is constituted by the following elements:

(1) .- body of the device, constituted by a cylindrical body, with two inner diameters, the outer one of smaller diameter

(2) .- hook proper, consisting of a cylindrical piece in the form of "L" and topped by a spherical thickening (8) that will be where the traction part of the trailer is adapted,

(3) .- internal thread, made inside the hook (2) and along the entire length of the horizontal part thereof

(4) .- hook stop (2) constituted by a cylindrical thickening located at its opposite end to the spherical thickening (8).

(5) .- threaded rod, integral with the rod head (6),

(7) .- electric motor.

The operation is simple, once the hook has finished the towing work, the electric motor (7) that rotates the head of the rod (6) is activated, which, being integral with the threaded rod (5), makes the hook (2) move backwards until it stops with the head (6) and so that at this time, the hook that has been hidden by rotation is in a horizontal position, so that the spherical thickening (8) is always in horizontal position so that it can be hidden underneath the vehicle body without disturbing at all

Describing sufficiently the nature of the invention, as well as the way of putting it into practice, it should be noted that the provisions indicated above and represented in the attached drawings are subject to modifications in detail as long as they do not alter its fundamental principles, established in the paragraphs above and summarized in the following claims.
