Description

Application area

The invention relates to the aviation, aviation and sports industry, and specifically to the paramotor (ragato! Og), which is used for motor paragliders (rotegab ragar1ape), is their power, power plant. A motor paraglider, in the sense of the present invention, is an ultralight manned aircraft made constructively in the form of a paraglider, that is, a parachute wing, on the slings of which a paramotor is fixed with a place for the pilot. A motor paraglider, being a safe and easy-to-operate tool for flying at low altitude, can be used for sporting events, as a means of entertainment, for eco-tourism, as a vehicle if you need to conduct any work on the inspection of territories from the air at low altitude, for example, huntsmen, nature reserve inspectors, flora and fauna researchers, as well as in other cases where this type of aircraft may be required.

State of the art

A paramotor is known, the design of which can be attributed to the classical type of paramotors, containing a frame with elements for attaching the paraglider lines, on one side of which there is a place for the pilot, and on the other, an engine with a propeller mounted on the shaft around which there is a guard mounted on the frame screw (BE No. 1011923 A6, IPC B64C, 2000, Fig. 6 and 7).

The construction of this famous paramotor is cumbersome, making it difficult to carry to humans, as well as transported by car.

A more compact design of a paramotor is known, in which an electric motor powered from an autonomous power supply is used as a power plant (ЕК No. 2817827 A1, IPC 7 В64С 31/036, 2002).

This known apparatus also includes a supporting frame, on one side of which a pilot seat is made, made of textile material with a tight seat, and on the other hand, an electric motor and an autonomous power source.

The screw in this known construction is made with three vanes that unfold when rotating under the action of inertia. The screw is removable and mounted on the motor shaft cantilever to ensure the safety of the pilot and the safety of the lines, since the enclosing structure of the screw is absent.

Despite the compactness of the known design, it takes up a lot of space in a passenger car and a special container is needed for its transportation. The weight of the known design is large enough that, despite the absence of a screw guard, makes it not convenient to carry.

In addition, modern autonomous power sources have insufficient resources, which makes the flight time on such a well-known apparatus not long enough.

In the photograph in FIG. 1 shows a collapsible paramotor known as the priority date of the present invention, “Miniplane M” (“M1shr1ape M”; 1Shr: // \\ l \ lg.1shshr1ape.e. /). This is the lightest and most compact paramotor currently available on the market of paramotors.

The known paramotor contains a supporting frame 1. On one side of the frame 1 there is a two-stroke engine 2 mounted on liquid fuel, a fuel tank (not visible in FIG. 1) and a collapsible safety guard 3 of the screw 4. On the other hand, the pilot's seat is fixed on the frame 1 5, made of textile material with a hard seat 6. Paraglider lines (not shown in FIG. 1) are attached to locks 7 on lines 8, with which the pilot fastens to the frame 1 with fixation in place of the pilot 5.

In this known paramotor frame 1 does not understand. When disassembling the device, the protective fence 3, screw 4, engine 2 and fuel tank, as well as the pilot's seat, are removed from the frame. All of these parts are packed in a plastic container, which occupies the fully luggage compartment of a small passenger car. This circumstance indicates the lack of compactness of the structure, the complexity of its transportation by road and the impossibility of prolonged carrying by a person. The dimensions of the plastic container go beyond the limits established for ordinary baggage when transported by air passenger transport.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention is to create a collapsible paramotor design that will allow to form a compact baggage in a disassembled state, convenient not only for transportation by ground, acceptable for transportation by air passenger transport, but also convenient for carrying by a person, which will allow the paramotor to be transported without the use of vehicles and to get the pilot on his own, on foot to hard-to-reach take-off places and get out of approved seats on their own in the event of a forced landing.

The indicated technical problem is solved by a paramotor containing a frame, a power unit and power unit controls, a removable propeller mounted on the output shaft of the power unit, a pilot's seat fixed on the frame, having conjugated back and seat, power belts for docking with the free ends of the paraglider and for pilot insurance as well as struts

- 1 011142 for breeding power belts for docking with the free ends of the paraglider above the seat of the pilot's seat in the direction of its length.

The frame is made of a motor one, on which, on the one hand, the power plant is fixed, and on the other, the pilot’s place, and the supporting parts. The motor and support parts of the frame are made with solid sides and are pivotally or detachably connected with the possibility of arranging at least part of the lengths of the sides of the motor and support parts along geometric ribs obtained by mating the planes of the four side faces of the figure in the volume of which the power plant is located.

Implementation of these conditions allows you to create a product that, when disassembled, will allow you to create a convenient luggage for transportation, the supporting frame of which is formed only from frame elements.

As a rule, the frame is made of metal rods.

Detailing of the construction is illustrated by the following particular cases of its implementation.

In the first embodiment, the motor part of the frame has a rectangular shape with protruding rods located perpendicular to its plane at two angles on one side, and hinges for connecting to the supporting part of the frame at its two corners on the other side.

The supporting part of the frame in this embodiment also has a rectangular shape with protruding rods located perpendicular to its plane at two angles on one side, the ends of which the supporting part is connected to the hinges of the motor part.

In addition, the frame in this case includes a locking element in the form of two parallel rods rigidly connected at the ends on one side of the parallel rods with a perpendicular rod. With the free ends of the parallel rods, the fixing element is pivotally fixed on the lateral sides of the motor part, and the ends connected by a perpendicular rod are detachably fixed on the supporting part of the frame, ensuring the perpendicular arrangement of the planes of the motor and supporting parts.

In addition, in this version of the frame, each spacer is made of short and long rods rigidly connected at right angles. The spacers with the free ends of the long rods are detachably fixed on hinges on the motor part along its opposite lateral sides with the possibility of rotation around the sides of the motor part, as well as around an axis perpendicular to these sides.

In the second embodiment, the motor part has a rectangular shape with protruding connecting rods located perpendicular to the plane of the motor part at its two corners on one side. The supporting part also has a rectangular shape with protruding connecting rods located perpendicular to the plane of the supporting part at its two corners on one side, and with protruding supporting rods located perpendicular to the plane of the motor part at its two corners on the other hand, the ends of which are connected by a crossbar.

The free ends of the connecting rods of the motor and support parts in this second embodiment are pairwise connected by hinges.

In the third embodiment, the motor and support parts have rectangular shapes and are detachably connected to an arrangement in the same plane.

The supporting part is made with protruding supporting rods located perpendicular to its plane at two angles from the side opposite to the side mating with the motor part, the ends of the supporting rods being connected by a crossbar.

Each strut in the third embodiment is made of short and long rods rigidly connected at right angles, while the struts with the free ends of the long rods are fixed at two angles of the motor part from the side opposite to the side mating with the support part, with the possibility of rotation around axes parallel to the lateral sides motor part.

The above-described forms of implementation of the paramotor frame construction make it possible to obtain a rigid and strong structure of the luggage carcass when the frame is brought into transport position, which will be shown in more detail in the examples below. In this case, a structure will be formed that is similar to the part of the backpack or backpack structure with an easel frame adjacent to the human back, which greatly facilitates the carrying of such baggage.

An important development of the design is in the form of a pilot seat. The back and seat of the pilot seat are associated with the possibility of relative rotation. The back of the pilot seat is made with turnable side sections, and the pilot seat is made in the form of folding sections. In this case, a shell of the structure brought to the transport position can be formed from the pilot’s position, which eliminates the use of an additional container for transporting the folded paramotor.

In all embodiments, the design may include a protective guard for the removable propeller in the form of radial bearings fixed by the ends on the motor part, and arcs associated with the second ends of the radial bearings to form a protective circle around the screw. A variant is possible when the arcs of the removable propeller guard located adjacent to it are fixed on the supporting part of the frame.

For the manufacture of motor and supporting parts of the frame, metal can be used.

- 2 011142 rods in the form of segments of hollow profiles or pipes made of steel, titanium or aluminum alloy. Similar sections can be used for radial bearings of the protective guard of a removable propeller. The arcs of the protective guards of the removable propeller can be made of pieces of hollow profiles or pipes made of elastic material.

The product can be equipped with straps associated with the motor part of the frame and located on the back of the pilot's seat, which are used to manually carry the product in its transport state as shoulder baggage (satchel, backpack). In flight straps are used for additional insurance for the pilot.

In FIG. 14, 15 show the frame construction made according to the third embodiment; on fig. 14 in flight condition, and on fig. 15 - in the folded transportation state.

The paramotor contains a frame made of two paired motor 9 and supporting 10 parts. On the motor part 9, a power plant 11 is installed with a removable propeller 12 on its output shaft. The power plant controls are not illustrated in the drawings.

The motor 9 and the supporting 10 parts are made with solid sides 13, 14 formed by metal rods.

On the motor part 9 from the side opposite to the attachment point of the power plant 11, a pilot seat is fixed having a conjugate backrest 15 and a seat 16.

The motor part 9 has a rectangular shape with protruding rods 17 (Fig. 3), perpendicular to the plane of the motor part 9 at its two corners 18 on the one hand, and hinges 19 for connection with the supporting part 10 at its two corners 20 (Fig. 2) on the other hand.

The supporting part 10 also has a rectangular shape with protruding rods 21 located perpendicular to the plane of the supporting part 10 at its two corners 22 on one side, the ends of which 23 the supporting part is connected to the hinges 19 of the motor part 9.

On the motor part 9, on the sides 13 in their middle part, the ends 24 of the fixing element having two parallel rods 25 connected on the other side by a rigidly perpendicular rod 26 are pivotally fixed. The ends 27 of the parallel rods 25 are detachably fixed to the supporting part 10.

On the lateral sides 13 of the motor part 9, spacers are fixed with the short 28 and long 29 rods rigidly connected at right angles by means of hinges 30 (Fig. 2).

The kinematic diagram of the hinges 30 is shown in FIG. 4. The hinges 30 enable the spacers (28, 29) to rotate around the axis 31, which ensures their rotation around the sides 13 of the motor part 9, as well as around the axis 32, perpendicular to the sides 13.

Spacers (28, 29) are connected to the hinges by detachable connections 33 (Fig. 2). The spacers (28, 29) are made with the possibility of connecting the short rod 28 with the protruding rod 17 of the motor part 9 in its continuation, and the end of the long rod 29 with the supporting part 10 in the continuation of its side 14.

The length of the rods 28, 29 of each strut (28, 29) is selected from the condition that if the struts (28, 29) are connected with the protruding rod 17 of the motor part 9 and with the side 14 of the supporting part 10 of the frame 9, 10 in the frame prepared for transportation state forms each side 13, 14 of both of its parts 9, 10 and the corresponding spacers (28, 29) rectangles that form

- 3 011142 rut the perimeters of the two sides of the baggage into which the paramotor is transformed in a state prepared for transportation. In this way, a structure is formed when at least part of the length of the lateral sides 13 and 14 of the motor 9 and the supporting 10 parts are located along geometric ribs obtained by mating the planes of the four side faces of the figure, in the volume of which the power plant 12 is located.

Radial bearings 34 of the protective guard of the propeller 12 are fixed by the ends 35 (Fig. 2) on the motor part 9, and at their ends 36 are fixed by the connecting elements 37 of the arc 38. Adjacent supporting parts 10 of the arc 38 are fixed by the ends 39 on the rod 26 of the fixing element (25 , 26).

The backrest 15 of the pilot's seat and the seat 16 are interconnected with the possibility of relative rotation at the same level with the hinges 19, connecting the motor 9 and the supporting 10 parts.

The length of the backrest 15 is equal to the length of the motor part 9, and the back of the pilot seat is made with folding lateral rectangular sections 42, the width of which is equal to the length of the protruding rods 21.

The length of the pilot seat seat 16 is equal to the length of the protruding rods 21 of the support part 10, and the seat 16 is made with three consecutive rectangular sections 44 connected along the outer edge 43 (Fig. 5), the total length of the first two of which is equal to the length of the motor part 9 and the length of the backrest 15 of the pilot seat, and the length of the third, extreme - the length of the protruding rods 21 of the supporting part and the aforementioned seat length 15.

After disconnecting the radial bearings 34, arcs 38, the removable propeller 12 and the spacers (28, 29), the rod 26 of the locking element (25, 26) is released, which moves in the direction of the protruding rods 17 of the motor part 9, and then moves on the hinges 19 supporting part 10.

Each spacer (28, 29) is connected by the end of the short rod 28 with the protruding rod 17 of the motor part 9, and the end of the long rod 29 with the supporting part 10 along its side 14. The assembled structure is reinforced with a fixing element fixed inside (25, 26). Hinges 30 rotate inward.

The nodes 45 of the connection of the motor part 9 with the protruding rods 17 and the nodes 46 of the connection of the support part 10 with the protruding rods 21 have inside the angles formed by the joined parts reinforcing the connection of the part 47, which are made with grooves 48 (Fig. 3), facing away from the vertices of the aforementioned corners. The disconnected radial bearings 34 and arcs 38 are inserted into the grooves 48 in packages 48 (Fig. 8).

The backrest 15 of the pilot's seat remains in the place where it is fixed on the motor part 9 in flight condition. Folding lateral rectangular sections 42 close the structure on the sides. The 16th seat of the pilot is located below. Associated with the seat 16, the two first folding rectangular sections 44 are located along the rear of the structure, and the extreme section 44 covers the structure from above (Fig. 10). The connection of the elements of the pilot's seat 15, 16, 42, 44 in the folded position can be provided with a zipper fastener.

A paramotor transformed into a fully enclosed container, which is illustrated in FIG. 11, provides for the presence of straps 49 located on the back side 15 of the pilot's seat for carrying the product. In flight, straps 49 are used for additional insurance for the pilot.

The suspension system of the power belts shown in FIG. 2 includes locks 50 for securing the lines 51 of the paraglider, supporting belts 52 of the suspension system, foot 53 and chest straps 54 with locks 55 (Fig. 5). The chest circumference 54 and the bearing belts 52 are moved apart by struts (28, 29) in the direction along the seat length 16 of the pilot's seat.

Elements of the suspension system when bringing the paramotor to the transport position are retracted inward. The straps 49 remain outside for carrying the product by man, and in the case of transportation by any means of transport can also be removed inside.

The invention provides for various embodiments of the frame.

In FIG. 12 and 13 show an embodiment including the execution of the motor part 56 of a rectangular shape with protruding connecting rods 57 located perpendicular to the plane of the motor part 56 at its two corners 58 on one side.

The supporting part 59 also has a rectangular shape with protruding connecting rods 60 located perpendicular to the plane of the supporting part 59 at its two corners 61 on the one hand, and with protruding supporting rods 62 located perpendicular to the plane of the motor part 56 at its two corners 62 on the other hand the ends of which are connected by a crossbar 63.

The free ends of the connecting rods 57 and 60 are pairwise connected by hinges 64.

The frame is brought into a folded state by turning the support part 59 relative to the motor part 56 on the hinges 64 until it contacts the upper part 65 of the motor part 56, as a result of which, as in the first embodiment, a frame is formed when the sides 66 and 67, respectively, of the motor 56 and the supporting 59 parts are located along geometric ribs obtained by mating the planes of the four side faces of the figure, in the volume of which the power plant 12 is located (not shown in FIGS. 12 and 13).

In FIG. 14 and 15 show a third possible embodiment of a paramotor frame in accordance with the invention. In this embodiment, the motor 68 and the supporting 69 parts are rectangular in shape and connected

- 4 011142 yen detachable with the same plane in zones 70 and 71.

The supporting part 69 is made with protruding supporting rods 72 located perpendicular to its plane at two angles 73 from the side opposite to the side mating with the motor part 68. The ends of the supporting rods 72 are connected by a crossbar 74.

Spacers in this embodiment are made of short rods rigidly connected at right angles to a short 75 and a long 76. The spacers (75, 76) with the free ends 77 of the long rods 76 are fixed at the corners 78 of the motor part 68 with the possibility of rotation around axes parallel to the lateral sides 79 of the motor part 68.

Bringing the frame in this embodiment into a folded state is done by disconnecting the support part 69 and then securing it with the ends 72 to the place of the initial interface with the motor part 68, but already perpendicularly. Then the spacers (75, 76) are rotated 180 ° and are connected by the free ends of the short rods 75 along the lateral sides 80 of the support part 69, resulting in a closed frame inside which the power plant is located (not shown in Figs. 14 and 15).

When carrying out the invention in any of the embodiments of the frame as a power unit 12, it is possible to use a two-stroke liquid fuel engine with an integrated gearbox or electric motor. The fuel tank 81 for the first case or the power source in the second case is fixed on the motor part 9, 56, 68, but can be fixed on the supporting part 10, 59, 69.

For the manufacture of the frame in all its variants, metal rods are used in the form of segments of hollow profiles or pipes made of steel, titanium or aluminum alloy, which are connected by welding. Similar segments can be used for radial bearings 34. Arcs 38 are made of segments of hollow profiles or pipes of an elastic material, for example polyamide.

Pluggable connections may vary. In the manufacture of parts from hollow pipe segments, these can be joints in the form of segments that fit one into another, fixed by rod parts, fixed forcibly, or self-fixed. To fasten the radial bearings 34, tie ropes (not shown in the drawings) can be used with locks to ensure the tension of the cables and their fixation.

The pilot's seat is made of canvases of flexible material, which can be used canvases made of woven material made of synthetic fiber or canvases made of sheet polymer material.

Thus, the implementation of the invention allows to obtain a design with low weight and small overall dimensions when folded, there is no need for a special container for transporting a paramotor in a transport state. All elements necessary for ground transportation of the paramotor are also present in its flight configuration. The assembled and packaged paramotor turns into a compact convenient baggage, a satchel that can be transported using the services of passenger airlines, as well as easily transported to a person over their shoulders for considerable distances on foot.
