Description

The utility model relates to transport engineering, namely to the frame of awnings mounted on bodies, mainly on small vehicles and trailers.

The widespread use of frames for tents of small trucks used for mobile transportation of goods in urban environments, where frequent re-installation of the frame is required depending on the particularity of the transported cargo and providing maximum access to the loading and unloading space of the body using special equipment to reduce time and costs in the process of work performed. In this case, the carcasses of the vehicle body must correspond to reliability and strength in order to withstand the impact of the load on the road.

Known folding awning of the vehicle (USSR author's certificate No. 1310248, publ. 05/15/1987, bull. No. 18, IPC B60J 7/12), containing a frame comprising a flexible bearing covering, transverse arcs, movably mounted on longitudinal guides and connected interconnected by pairs of pivotally connected levers, while inside the tent frame there are compressed air sources with an air system to prevent the lateral parts of the tent (flexible coating) from falling into the movable levers.

The disadvantage of this design is its complexity and bulkiness, while the useful volume of the body is reduced and additional operating costs for maintaining the air system are required.

The closest technical solution and the achieved technical result is a folding awning for the vehicle (copyright certificate No. 981025, publ. 12/15/1982, bull. No. 46, IPC B60J 7/12). The folding frame of the awning of the vehicle body includes arcs located one after another, supporting the awning, which are movably mounted on longitudinal guides with a longitudinal groove, located along the body, articulated with levers, the latter are interconnected in pairs.

The disadvantages of this design are

 insufficient reliability of the structure and its functioning, since the open parts of the moving structural elements kinematically connected to each other when moving and sliding along arcs are subject to precipitation and dust, which entails premature wear and the possibility of jamming, and various contaminants getting into the upper longitudinal a groove of guides in which the ends of the movable arcs and drive elements are placed leads to a malfunction of the folding frame;

 insufficient rigidity and vibration resistance of the structure, since the upper parts of the arcs are not supported by each other;

 lowered upper folds of the flexible coating down during loading reduce the useful volume of the body, and falling rain in the form of rain, snow, dust between the folds of the tent and also because of the folding of the tent repeatedly leads to premature wear;

 the possibility of getting the side of the tent into the lever system, which leads to disruption of the folding frame.

The objective of the utility model is to create a compact design of a folding car body tent frame, improving its operational characteristics by increasing the degree of reliability of its operation with minimal labor costs for its maintenance in difficult road operating conditions.

The technical result is an increase in the rigidity and vibration resistance of the structure, an increase in its operational reliability, as well as the ability to move the block or individual sections along the side of the vehicle body during loading and unloading, the possibility of building sections of the side of the body.

This is achieved due to the fact that the folding frame of the awning of the vehicle body, including arcs located one after another, bearing the awning, which are movably mounted on longitudinal guides with a longitudinal groove, located along the body, pivotally connected to the levers, the latter are pairwise connected between by itself, according to the utility model, arcs are combined into pairs of arcs, each pair of which is movably connected in the upper part with the introduced parallelogram mechanism, and pairs of levers pivotally interconnected They are at the same level without sliding along the arcs, while they are made of the same length and are set back and forth between the said pair of arcs in a horizontal position with the possibility of their rotation to the vertical position by an articulated joint between the levers upward, and the movably mounted pairs of arcs kinematically connected by parallelogram mechanisms and levers contact with each other, forming a block of similar sections, while the sections are interconnected by latches, and the front section of the block is latched to the front fixed b mouth of the body.

The levers and arcs can be box-shaped and interconnected by hinges attached between the levers to their lower walls, and along the edges of the levers to the side and upper walls of the corresponding arches and levers.

The ends of the levers pivotally connected to the arcs can be installed in the U-shaped guiding elements that are fixed on the arches, and at the junction of the levers, the introduced U-shaped guiding elements are mounted on one of the levers.

The longitudinal groove of the longitudinal guides can be made on the outside of the vehicle body.

A cable for tightening them can be installed in the upper part of the block of similar sections, passing through the front and rear arches of the section block through the inserted clamps located in two places of the above arcs, and the ends of the cable are fixed by the inserted turnbuckles to the installed rotary arch of the rear side of the vehicle body.

On the outside of the arcs, handles can be installed.

Each of the guide elements, mounted on one of the levers, can be equipped with a release mechanism, which ensures that the levers turn up.

The lower ends of the arcs of each section can be mounted on movable elements that are selected from known standard devices for this purpose, for example, rollers.

The folding frame of the awning of the vehicle body contains arcs 1 on which the awning 2 is mounted. The arcs 1 are movable on longitudinal guides 3 with a longitudinal groove 4 made on the outside of the body 5, while the longitudinal guides 3 are fixed in the lower part of the body 5. Arcs 1 are pivotally connected to levers 6 and pairwise interconnected. Arcs 1 are combined into pairs of arcs, each pair of which is movably connected in the upper part by a parallelogram mechanism 7, and pairs of levers 6 pivotally connected to each other are mounted at the same level without sliding along arcs 1 and are made of the same length. The levers 6 are installed in opposition between the aforementioned pair of arcs 1 in a horizontal position with the possibility of their rotation in a vertical position by a swivel between the levers 6 up. The front pair of arcs 1 is also connected to the front of the vehicle body 5, moreover, the movably mounted pairs of arcs 1 kinematically connected by parallelogram mechanisms 7 and levers 6 are in contact with each other, forming a block of similar sections 8, while sections 8 are interconnected by latches 9, and the front section of the block is connected by a latch 10 with the front fixed side of the body 5.

The levers 6 and arcs 1 are box-shaped and interconnected by arcs with hinge hinges 11, which are fixed between the levers 6 to their lower walls, and along the edges of the levers 6 to the side and upper walls of the corresponding arcs 1 and levers 6.

The ends of the levers 6, pivotally connected to the arcs 1, are installed in the guide elements 12 of the U-shaped, which are fixed on the arcs 1, and at the joints of the levers 6 are installed inserted guide elements 12 of the U-shaped, mounted on one of the levers 6 .

A longitudinal groove 4 of the longitudinal guides 3 is made on the outside of the vehicle body 5 to prevent contaminants from entering the movable elements 13.

In the upper part of the block of similar sections 8, a cable 14 is installed for tightening them, passing through the front and rear arcs 1 of the block of sections 8 through clamps 15 located in two places of the above arcs 1, and the ends of the cable 14 are secured by lanyards 16 to the rotary arc 17 of the rear side of the body 5 vehicles. On the outer part of the arcs 1 mounted handles 18, 19.

Each of the guide elements 12, mounted on one of the levers 6, is equipped with a release mechanism 20, providing the rotation of the levers 6 up.

The lower ends of the arcs 1 of each section 8 are mounted on movable elements that are selected from known standard devices for this purpose, for example, rollers 13.

In the transport position, the folded frame is blocked from movement, for example by a stopper (not shown in the drawing).

Folding frame awning vehicle body works as follows.

When filling the body 5 with the load, the frame is unfolded (see Fig. 1). After removing the stopper, the block of sections 8 in the folded state, secured by latches 9 between the sections 8 and the latch 10 with the front fixed side of the body 5 by means of the handle 18, is moved along the longitudinal guides 3 with the side longitudinal groove 4 on the rollers 13 to the rear side of the body 5. Under the action of tensile the efforts of one person or a special drive with a large number of sections 8 (not shown in the drawing) stretch parallelogram mechanisms 7, linking the arc 1 in the upper part of the frame. Arranged between themselves and the arcs 1, the levers 6 under the action of tensile forces and their own weight are moved from a vertical position to a spacer between the arcs 1 in a horizontal position, linking the arcs 1 to each other in the middle part of the frame. The ends of the levers 6 are lowered into the guide elements 12.

Through the clamps 15 located at the edges of the upper horizontal part of the front and rear arcs 1, the cables 14 are passed. The ends of the cables 14 with lanyards 16 are fixed to the rotary arc 17, additionally connecting sections 8 to each other in the upper part of the frame.

On the cables 14, the awning panel 2 unfolds or unfolds by the efforts of one person. Awning 2 bends around the perimeter of the arched top of the arcs 1, while longitudinal and side curtains are fixed to its lower edges, enveloping part of the tent 2 (not shown in the drawing). The edges of the side curtains with an inlet are tucked under the longitudinal curtains. Awning 2, having grommets, brackets and other accessories of furniture, through which cables are used to fasten the tent to the vehicle body 5.

To unload the body 5, folding of the frame is performed (see Fig. 2).

After disconnecting the awning 2 from the body 5, the canopy of the awning 2 is folded up or wrapped on the cables 14 and retracted into the body 5. Using the lanyards 16 and clamps 15, the tension of the cables 14 is loosened, the ends of which release from fastening to the rotary arch 17. To bring the frame into position for folding it, the levers 6 are moved from a horizontal position to an inclined position in order to achieve a minimum angle that ensures the subsequent movement of the levers 6 into a vertical position using a release mechanism 20 with manual or a mechanical drive for each pair of levers 6. By means of the handle 18, the block of sections 8 is moved to the front side of the body without unfastening the latches 9 and 10, while the parallelogram mechanism 7 of each section 8 is compressed until the levers 6 move into a vertical position with a loop hinged 11 up. The freed ends of the cable 14 are fixed to the rear arc 1. In the folded state, the frame is blocked from moving by the stopper during transport operations.

A feature of this design is that to ensure maximum access to the body 5 during loading and unloading, using the handles 18,19 and disconnecting the latch 10, the entire block of sections 8 can be moved along the entire length of the body 5. By disconnecting the latches 9 using the handles 18, it is possible move individual sections 8 of the block or in any combination thereof.

The above-mentioned features of the frame make it possible to increase its operational characteristics, making it possible to fully utilize the volume of the cargo space of the body by moving the block or individual sections along the length of the body during loading and unloading operations.

It is possible to build the frame in separate sections and dismantle them with minimal labor costs when servicing the frame with one person.

The presence of connecting elements that increase the connection of the arcs of each section according to their height, as well as among themselves, increases the rigidity and reliability of the structure as a whole. The folding frame is made of the same parts, which simplifies its design and reduces labor costs in its production.

This design made it possible to obtain the claimed technical result on a prototype manufactured by the authors on a Gazelle small-capacity vehicle.
