(2.5) each located on both sides preferably on the upper part of the base structure (2), giving the

load structure (1) a degree of linear freedom of movement along these rails (2.5). The linear movement of the load structure (1) through the rails (2.5) is produced by the action of at least one winch (2. 8) installed at the rear of the base structure (2) and preferably at the same height as the rails (2.5). The steel cable (2.20) of the winch (2. 8) runs through at least one pulley (2. 16) located in a japan

(2.1) on the back of the module (3) of the present invention and said jacena (2. 1) connected to the base structure (2) through two pillars (2. 2) that preferably raise it between 1 and 1 , 5 meters above the rails

(2.5) to then connect the cable (2.20) of the

winch

(2. 8) with other system from pulleys (1.11) located

in

the for you higher from the structure from load (one) the which

remains

connected with the winch (2.8).

In figure 2 where the parts that form the base structure (1) of this example of a winch and unloading module driven by winch (3) are shown, whereby such structure (1) is extensible in length, width and height set that each extensible element of its structure (1) is a preferably metallic and rectangular section tube that contains another tube in its interior with a section smaller than this but of similar lengths and joined the tube of smaller section by one of its ends to the base structure (2) and the larger section tube joined at the opposite end to said structure (2) such that the inner tube runs inside the outer tube when the extension of the structure (2) occurs, and thus being able to adapt to any cargo box (4. 1) of any vehicle (4) that is in its dimensional range.

As shown in Figure 2, to facilitate the

transfer and handling of the charger and unloader module (3) outside

of the vehicle (4), it has been preferably provided with four

folding legs (2.13) with wheels (2.21) at their ends, with

5

a distribution of at least two legs (2. 13) on each side

of the base structure (2). Said legs (2.13) comprise the

less an axis of despondency in its upper part, than to

through at least one spring (2.14), they can after being

Down 90 degrees, return to its original position.

10

The base structure (2) of the charger module and

downloader (3) comprises at its back, at least two

pillars (2. 2) that protrude with a height determined by

above the base structure (2), preferably between 1 and 2

fifteen

meters, which preferably hold by means of screws,

a jacena (2. 1) located at the top of said

pillars (2.2), formed by an extensible metal bar in

length, in which at least one pulley (2.16) is mounted on a

mobile system (2. 15), which surrounding the bar (2.1), is

or bearings (2.17) that are inside

said system (2. 15).

Such structural assembly, formed by the pillars (2.2)

2S

and jácena (2.1), described above, are attached to the

base structure (2) by means of at least one hinge (2.18)

located at the lower ends on both pillars (2.2),

giving them an angle of dejection to be

folded when the charger and unloader module (3) has

30

that transport by road or be stored in garage;

reducing in height, one of its largest structures.

In addition the center of the jacena (2. 1) is articulated

allowing the charger and unloader module (3) to

fold over itself as seen in figure 10 and figure 11.

As contemplated in Figure 2, the structure

The base (2) comprises in its upper part, two rails (2.5) each located on both sides and preferably fixed by screws to the front pillars (2.11) and to the rear pillars (2. 12) of the base structure (2) . The load structure (1) is attached to the base structure (2) through

10 the rails (2. 5), which grant freedom of movement to the load structure (2) along them. Said rails (2.5), preferably have an inclination angle of between 10 to 30 degrees with respect to the ground, with greater height in the rear area and less height in the area

Previous 15 of the rails (2. 5), in this way, the load structure (1) can advance towards the front part of the loader and unloader module (3) by action of the gravity of the earth to which the weight is subjected of this, said advance being controlled with the winch (2. 8), since

20 its cable (2.20) is connected to the pulley system (1. 11) located at the top of the load structure (1).

The rails (2.5) comprise at each of its rear ends a segment of rail (2. 10) with a length 25 preferably between 1 and 0.5 meters, and with the same profile as the rail (2. 5) that precedes; such segments (2. 10) are attached to their respective rails (2.5) by at least one hinge (2.9), for when the module expands in length

loader and unloader (3) these segments (2.10) can be folded to an angle of 0 degrees with their

respective rails (2.5), increasing the length of these.

On the other hand, the rails (2.5) each comprise at their previous ends a curved extension (2,7) with their same profile and joined said extensions (2 .7) to each one

from

these by to the less a hinge (2. 6), for that to the

transport

he module charger Y Downloader (3) by

highway,

East keep up the extensions curves (2.7) from

the

rails (2.5) inside of the vehicle (4) by reasons from

security .

As can be seen in Figure 7, the main function of these extensions (2. 7) in the form of an arc of circumference is to anchor the load structure (1) at its end by the pressure action it exerts in said position on that point of the rail (2.5), and thus adopt a position parallel to the ground that facilitates the loading and unloading of heavy objects with the exterior of the vehicle.

The base structure (2) represented in Figure 2, comprises at least one winch (2.8) mounted on a mobile system (2, 3), very similar to the mobile system (1.10) with the pulley (1. 11) of the structure loading (1); said system

(2.3) it is mounted on a jácena (2. 4) supported by the rear pillars (2.11) of the base structure (2) and attached thereto preferably by at least one screw at each end; in this way, the mobile system (2.3) gives the winch (2. 8) a degree of freedom of movement along the japan (2. 4), by the action of bearings (2.17) positioned inside the system mobile (2.3) and surrounding the jacena (2. 4) by its surface. Said Jacena

(2.4) It has a rectangular section, extensible in length and is articulated in its half to allow the loading and unloading module (3) to fold over itself as seen in figure 10 and figure 11.

As shown in Figure 2, all the bars contained in the width of the base structure are articulated in half, so that in this way, the loading and unloading module (3) of the present invention can be folded on itself, reducing its width considerably, so that in this way it occupies less space in the place where it is intended to be stored, as contemplated in Figure 10 and Figure 11.

Figure 1 shows the load structure (1) of the loader and unloader module (3), which comprises at least two pillars (1.2), which are joined at their upper ends to a jácena (1.1) preferably by the minus one screw (1.9) at each end. The jácena (1.1) located at the top of the load structure (1) can be extended allowing said structure (1) to be able to increase its width preferably between 1 and 0.5 meters.

Furthermore, said structure (1) comprises a set of pulleys (1.11) mounted on at least one mobile system (1.10), which surrounds the jácena (1.1), being able to move

he

set from pulleys (1.11) next to mobile system (1.10) to

the

long from is. He system mobile (1.10) be moves to

through

from the jacena (1.1) by means, medium from nail wheels or

bearings (1,13) that are inside said system (1.10), allowing the latter a degree of freedom of movement along the surface of the jacena (1.1).

To facilitate the folding of the module (3) on itself as shown in Figure 10 and Figure 11, the jácena

(1.1) it has at one of its ends a joint (1. 7) by means of a safety pin (1.8) so that when the joint is removed (1.7), the jácena (1.1) can detach from the pillar

(1.2) And placed at an angle of 0 degrees with respect to the other pillar (1.2) And thus allow the folding of the loading and unloading module (3) of the present invention.

In the embodiment of Figure 1, each pillar (1.2) of the load structure (1) comprises at its lower end at least one base tube (1.5), an angular regulation tube

(1.4) and a support bar (1.3) with rectangular and preferably metallic sections, arranged in a triangular shape; which fulfill the function of giving stability to the pillars (1. 2) of the load structure (1) by having each pillar (1.2) rest on the upper end of each of the support bars (1. 3) , giving the pillars (1.2) an inclination angle preferably, between 70 and 50 degrees with respect to the rails (2, 5), in order to be able to adjust said angle according to the slope of the terrain to which the loader module is subjected and downloader

(3), so that, at a greater slope of the terrain, a smaller angle would adopt the position of the pillars (1.2) of the load structure (1) with respect to the rails (2.5).

As seen in figure 1, each base tube (1, 5) comprises at each of its ends two ex is made of steel

(1.14) perpendicular to it, and in turn, each axis (1.14)

understands

in its extreme opposite to the tube base (1.5), a

Bearing

linear (1. 6), he which goes inserted in its

respective

rail (2.5), for So endow from movement to the

structure

from load (one) to the long from the rails (2.5)

located on the sides of the base structure (2).

Each pillar (1.2) of the load structure (1) is connected through a steel shaft (1 .14) to one of the two ends of its respective base tube (1, 5), and in turn, through the same

point of attachment between the pillar (1.2) and the base tube (1.5), goes

also joined by one of its ends, the regulation tube

angular (1.4), allowing an axis of rotation between these

structural elements in the same direction as the axis of

S

steel (1.14) that acts as a union.

The angular adjustment tube (1. 4) at its end

opposite to the union with the pillar (1.2) and the base tube (1, 5),

stays attached to the support bar (1.3) through one

10

of the angular adjustment holes (1.15) made at

along said bar (1.3), by means of at least one bolt or

pin (1.16), as and as contemplated in figure 1,

allowing to regulate the degree of inclination of the pillars

(1.2) of the load structure (1) depending on the hole

lS

(1. 16) to which said end of the regulating tube fits

(1.4).

As can be seen in figure 5 in this example of a

winch and loader module powered by winch (3),

twenty

shown as it is installed in a vehicle (4) with box

cargo (4.1), which in this case is a trailer (4). He

operator after adjusting the structure of the charger module and

unloader (3) with the same dimensions as the interior

that the cargo box (4 .1) of the vehicle (4), this is

2S

introduced by the back of said vehicle (4) to

through the front of the charger and unloader module

(3), pushing it into the loading area (4.1) of the

vehicle (4) and while the module (3) advances towards the

inside, the legs (2.13) are folded until they are

30

parallel to the floor of the loading area (4. 1) and the module (3)

completely introduced, to later adjust the

anchor structure (2. 22) that connects the base structure

(2) of the charger and unloader module (3) with the chassis (4.2)

of the vehicle (4) through an inverted T-shaped structural element (2.23) located at the end of said anchoring structure (2.22) and being traversed below the chassis (4.2) preventing the front part of the module from being lifted (3), due to the lever effect generated by the moment of loading weight when it is unloaded or picked up by the rear of the vehicle (4).

Figure 7 shows the different positions that the load structure (1) can acquire through the rails (2.5) of the base structure (2) by the action of the winch (2.8) indicating the position parallel to the continuous line floor of the load structure (1) for the unloading or collection of heavy objects by the rear of the vehicle (4), and in a broken line the different positions of the load structure (1) until completing its route through the rails (2.5) longitudinally transporting said load to any part of the interior of the vehicle (4).

As shown in Figure 8, in this example of a winch and loader module driven by winch (3), the transverse movement that can be performed is indicated by simply moving manually the mobile system (2.3) of the winch to the along the jacena (2. 4) where it is subject, which transmits said movement to the mobile system (2. 15) with pulley (2.16) of the base structure

(2) and to the mobile system (1.10) with pulleys (1. 11) of the load structure (1) through the steel cable (2.20) of the winch (2.8) that connects this whole assembly, and thus, together the longitudinal movement of the cargo structure (1) along the rails (2.5) of the base structure (2), it is allowed to subtract or place the cargo at any point in the cargo area (4.1) of the vehicle (4) ).

It can be seen in figure 7 of this example or of a module

loader and unloader (3), a cylindrical body (2.24)

preferably metallic, jointly and severally connected to the cable

(2. 20) of the winch in the area near the hook (2.25);

5

so that the cable (2.20) when picked up by the winch

(2. 8), the cylindrical body (2.24) comes into contact with the

locking device (1.12) preferably electronic and

controlled by remote control that is installed

around one of the pulleys (1.11) of the structure of

10

load (1), which catches the cylindrical body (2. 24) to

then the load structure (1) was unlocked from the rail

(1) and the winch (2.8) through the cable (2.20) pull

the load structure (1) generating the displacement of

this along the rails (2.5). This device

fifteen

electronic (1.12) blocks the end of the cable (2.20) by the

clamp that creates in the cylindrical body (1.12) so that in

if the module (3) is loaded, the load is maintained

suspended in the air held by the hook (2.25) without the

possibility of rushing uncontrollably on

twenty

vehicle (4).

As shown in Figure 2, of this example of a

winch and loader module powered by winch (3)

comprises on the top of one of the rails (2, 5) of

~

the base structure (1) a series of holes (2. 26)

made at the same distance along said rail

(2.5), so that when placing the load structure (1) in the

area where you want to deposit or subtract any cargo

from the cargo box (4.1) of the vehicle (4), the operator can

30

insert a bolt into the hole (4. 1) that is between

the two bearings (1.6) located at the lower end

of the pillar (1. 2) of the load structure (1) that matches

with that rail (2.5) and thus produce the blocking of said

structure (1) at that point of the rail (2.5) to then be able to remotely release the disc body (2. 24) together with the cable (2. 20) of the winch (2. 8) that was anchored in the locking device (1.12), and thus being able to deposit or subtract the desired cargo from the loading area (4.1) of the vehicle (4) making the hook

(2.25) raise or lower controlled by the winch action

(2.8).

As shown in Figure 9, in this example of a loader and unloader module (3) after placing the load structure (1) at the rear end of the rails (2.5) and then fold it forward resting on the base structure ( 2) and then remove the respective bolts (1.16) of each angular adjustment tube (1.14) and folding the support bar (1.3) and the regulation tube

(1.14) backwards, the load structure (1) is left. The highest part of the base structure (2) is folded forward by the joint through the hinges (2.18) that are located at the lower ends of the pillars

(2.2) being supported on the load structure (1). The segments (2. 7) located at the front ends of the rail are (2.5) in the form of an arc of circumference protruding from the vehicle (4) fold inward, so that all the highest and protruding parts of the vehicle (4) are collected inside the cargo box (4. 1) so that the module (3) can be transported by road installed in the cargo area (4. 1).

As can be seen in this example of a winch-loaded loader and unloader module (3) of figure 10 and figure 11 in which it appears folded over itself in width and height, since all the elements

Structural elements that are located in a transverse position to the loader and unloader module (3) contain in their middle part a joint (2.19) that allows them to be folded, except for the jácena (1. 1) of the structure of S load (1) that the bolt (1.8) must be removed from the joint with one of its pillars (1.2) to be placed parallel to each other and folded over the base structure (2), and the raised structure that is located at the back of the structure base (2) is folded back in height and 10 later folded in width inward as its jacena

(2.1) is articulated in its half; in this way the module (3) is folded in width and height to occupy less space in the place where it is intended to be stored.
