Description

FOLDING LOADING DEVICE FOR VEHICLES APPLICATION OF THE INVENTION

The present invention relates to a device adaptable to cargo vehicles, which allows loads to be transported that exceed the dimensions of the cargo area of said vehicles or to prevent the cargo from having direct contact with the vehicle body.

BACKGROUND OF THE INVENTION In the presently known ways to adapt racks, shelves or "rads" on the beds of cargo vehicles, there are a large number of structural configurations for building and mounting said devices on the vehicles. One of the main disadvantages that is found in most of the aforementioned loading devices, is that its structure rests on points of the body of the vehicle, which limits its ability to support the maximum weight for which the vehicle was originally built. vehicle, given that the aforementioned points of the body are not designed with the estnictural force to support the main load that has to rest on the frame or chassis of the vehicle.

Another important disadvantage of most known devices is that the fixed structure of other devices limits the use of the bed or box of the cargo vehicle when occupied by the structure of the device itself. In addition to the fact that in cases when cargo is not transported that requires resting on the device and the structure of the device exceeds the height, width and length of the vehicle itself, the device is cumbersome, limits visibility in some way of the driver and becomes aesthetically unpleasant the appearance of the vehicle.

Some of the devices in the state of the art can be found in the following patent documents:

1. "US2016059906A1" .- (2016) US patent application that discloses a modular rack or rack system for request box and parts of the system. The inventor writes as innovative in the system the use of bars and pieces adaptable to the prindpal structure of the shelf to carry additional accessories to the prindpal load that accepts the shelf or rade This is a structure with Unlimited load capacity, being recommended to leave it permanently installed in vehicle, given its complexity of assembly.

2. "US2016096481Al" .- (2016) US Patent SoRdtud that writes the Invention of an expanded loading device to adapt to the aforementioned dimensions of boxes or beds of cargo vehicles. Regardless of whether it is necessary to be carried out on the box or vehicle where it is installed, the novelty is focused on its ability to expand and contract. This quality of expansion limits the load capacity of the dd dspodOvo structure itself when it is required to be manufactured with tubular pieces of different dimensions and sizes that allow it to be made of its extensive or telescopic melt.

3. "US2016197653Al" .- (2014) SoRdtud of a US patent that discloses an abatiole charging device, which points can be assembled and disassembled without tools. B device is mainly composed of tubular pieces joined by clamps. B fully assembled device is mounted on side supports ⁽ refurbished in the vehicle box. Even when it is indicated as an advantage of mounting and disassembly without the use of tools, it really requires the development of great manual ability to perform this task, in addition to the oompiejkfad to identify the location of each piece that makes up the structure. 4. "US6033002AV (2000) Estefotinidense patent that draws a folding device and a hidden storage system for a pick-up bed. The possibility of installing a support installation to the floor of the pick-up box is described, which It can be hidden in the side walls of the box.The structure where the load rests, has means to extend its height and a piece in the upper frame that allows to obtain an extension of the rack above the cabin of the vehicle. down, this device requires the disassembly of some parts to be able to fold it in the box of the vehicle.

5. "US4699131A1" .- (1967) US patent that refers to an abatiole charging device for pick-up. When this device is retracted or folded down, it rests on the side walls of the vehicle case. The main structure is composed of 6 vertical posts where the pairs in the middle and back of the box are hinged to fold over the side walls of the box. The posts have assembly means for mounting and securing the horizontal posts that give the structure a complete shape. The disadvantage of this dsposltivo is that the structure that forms it requires too much time to assemble and disassemble, in addition to being applied for a single person to perform this work. Another disadvantage is that it requires leaning on the vehicle's tan.

In general, most of the loading devices to be installed on the boxes or beds of vehicles, require stictural sections that join the front and rear frames of said devices, having as a disadvantage in all of them the presence of said lateral sections, due to the difficulty of loading and unloading the vehicle laterally, since this process is established in common practice with the use of forklifts of the type * fbrk Hit *.

The present invention relates to a mechanical device or device that allows it to be mounted on the loading points of the bed or box of a vehicle, having a foldable configuration to lie on the vehicle box when it is not required to carry load on the device, remaining hidden from outside view of) vehicle and releasing cargo sword from the vehicle itself. □ present otsposiPYo is conosono to adapt in oiseno, structural resstenaa and dimensions to load different types of objects, such as construction materials, bicycles, motorcycles, canoes and boats to navigate, including the ability to exchange the frames of the device so that they are the ideal ones to the type of load that is tried to take in the vehicle.

B device consists of two main stitches (1 and 2), which are each made up of a frame made of two parallel tubular pieces (la and 2a) that make the smelter of vertical posts when the device is deployed to receive load, and a superior crossbar (le and

2c) on which the load rests, each frame has a second crossbar (le and 2e) to increase the structural strength of said frames. Each of these frames (1 and 2) has at d extreme opposite to the location of the upper crossings (le and 2c) transverse perforations within which it is housed internally and in a hidden way a dubricular tubular section as bushing (lg ) through which rods or thymes are passed, which serve to hold the frames to bases that are fixed to the bed or box of the vehicle in which the device is installed, said hinge rods being used to fold the frames onto the dd bed vehicle, when cargo is not required. The posts (the and 2nd) of the frames (1 and 2) of the device, each have a straight section and an oblique section (Ib and 2b) with respect to the vertical. The ends of each upper crossbar (le and 2c) are open to allow a telescopic extension (lf) to be inserted at each end in order to extend the loading surface width of each upper crossbar

(lc and 2c) and prevent the load from moving laterally and falling from the vehicle (5). The upper crossbars (le and 2c) and the telescopic extensions (10 have a series of holes (10c) that pass side by side through their side faces, where metal pins (100c) are placed perpendicularly, which serve as a safe way to choose different distances from the position of the telescopic extensions (lf) to expand or reduce the width of the surface of the upper crossings (le and 2c) to reduce load.

B lower traverse (le and 2e) of each frame (1 and 2) is located at d point where each of the first straight sections (la and 2a) end,

Right where they join the base of the oblique sections (Id and 2d). This configuration of obOcua section of the frames (1 and 2) is ideal for folding them down when the bed (5a) of the vehicle (5) is not completely flat, this is generally due to the space occupied by the rear wheels of the vehicle (area of the manshafts) ), allowing to completely lower each frame

(1 and 2) on the bed (5a) of the vehicle (5). When the bed (5a) of the vehicle is completely flat, the frames (1 and 2) can be manufactured with the vertical posts (la and 2a) completely straight, without the need for oblique sections (Hg. 16).

Each frame of the device is reinforced structurally, according to the need and the carrying capacity of the vehicle (5), by sharpening at least one reinforcement post (Id) that is installed perpendicularly between the upper crossbar (le and 2c) and the lower crossbar (Id and 2d) of each frame (1 and 2), helping the dead weight of the load to be distributed among the two crossbars of each frame and right load is not supported only by the upper crossings (le and 2c).

The rear frame (2) has substantially the same structure as the front frame (1), and its posts (la and 2a) can have a completely square shape in cases where the bed (5a) of the vehicle (5) is completely flat ( Rg. 16).

The base (3) where the front frame (1) of the vehicle (5) is fastened, is coriformed by a pair of vertical metal sections (3a) of type V profile each joined at its ends Lower than a pair of metal plates

(3b) that have at least one hole (30c) through which threads (300a) are passed to fix this base (3) d bed floor (5a) od vehicle chassis (5). Each vertical section (3a) of this base (3) each day has a pair of transverse perforations, a Lower (30b) and a superior (30a), serving the Lower (30b) to pass a stem or tomiHo (100b ) which in turn is passed through the lower perforation (10b) of each post (the), making the hinge function to fold down the front frame (1) on the bed (5a) of the vehicle (5) and, in each upper perforation (30a) of each of these vertical sections (3a) a rod or screw (100a) is passed, which pass through each upper perforation (10a) of each post (the) when the frame (1) is It is deployed or in a position to redraw cargo, allowing that a frame (1) remains in position and does not get caught when receiving cargo or putting the vehicle (5) in motion. Each stem or thyme (100a and 100b) used is of a diameter sufficiently small d of the holes (30a and 30b) in the base (3) and d of the holes (10a and 10b) in frame d (1), to allow them to said rods or holes (100a and 100b), slide freely inside d of the recessed holes but with the minimum clearance between d outer diameter of the rods (100a and 100b) and d inside diameter of the holes (30a and 30b) . Inside each hole A metal bushing (lg) is installed at the bottom of the vertical posts to give greater load resistance to said vertical posts.

The vertical sections (3a) of the base (3) that supports the front frame (1) are joined at their upper ends by a metal profile section

(3c) installed perpenolcularly with respect to two vertical sections (3a), the profile (3c) of the section preferably being a metal angle, the Inner face of said angle section (3c) being oriented towards the vehicle cabin (5) and at a height that allows it to be attached to the edge of the box (5a) of the vehicle (5), giving greater structural support to the base (3) and a firmer support for the front frame (1) when it is deployed to receive cargo .

The internal part of the "c" profile of each vertical section (3a) of the base (3) is slightly wider than the width of each post (the) of the front frame (1) so that when deploying said frame (1) , these posts (la) are within the form dd profile "c", with the perforations (10a and 10b) of the posts (la) and the perforations (30a and 30b) of the vertical sections (3a) of the base ( 3), aligned so that the rods or screws (100a and 100b) connecting the front frame (1) with the base (3) can be shifted through days.

B rear frame (2) dd device is attached to the bed (5a) dd vehicle (5) by means of two socket bases (4) that are previously installed on the sides of the internal rear area of the bed (5a) dd vehicle (5) . Each of these bases (4) is made up of a lateral vertical section (4a) constructed with a metal profile joined lengthwise in one of its edges to the outer face of a section of profile type "c" (4b), forming both pieces a square that is reinforced with at least one pair of metal plate triangles (4c) welded on the inside of said square. At the bottom of each base (4) is attached to the square The vertical metal sections (4a and 4b) form a metal plate (4d) which has at least one hole (40) through which a thyme (400) is held that holds each base (4) to the vehicle floor (5) ). This plate (4d) of the base (4) has on its rear edge an eyebrow that is coupled to the rear edge of the bed (5a) of the vehicle (5) to give greater fixation to said base (4) and a firm hold on the rear frame (2) when installed in the bed (5a) of the vehicle (5).

The profile section type "c" (4b) of the bases (4) supporting the rear frame (2) each has a top hole (200a) and a bottom hole (200b), substantially similar to coughs presenting the vertical sections (3a) of the front base (3), with the lower holes (200b) having the hinge cast to fold the rear frame (2) onto the bed (5a) of the vehicle (5) and the upper holes (200a) ) the die to keep the rear frame (2) in position once deployed to reduce load.

The internal part of the profile "c" (4b) of each rear base (4) is slightly wider than the width of each post (2a) of the rear frame (2) so that when said frame (2) is deployed, these posts (2a) are within the form of the profile V (4b), with the perforations (20) of the posts (2a) and the perforations (200a and 200b) of the "c" profiles (4b), set so that they allow sliding through coughs or stems (50) that join the back frame (2) with each of these bases (4).

The lateral vertical section (4a) of each rear base (4) has at least one hole (60) through which dummies (600) that fix these bases (4) laterally to the box (5a) of the vehicle ( 5). The upper crossings (le and 2c) of each frame (1 and 2) can be located at the same height to align horizontally with the load or remain d upper crossbar (2c) gives rear frame (2) slightly by oeoajo oe the height of the upper crossing (le) of the front frame (1), to end the vehicle loading and unloading process (5) from the rear of said vehicle (5).
