Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a radio-controlled paraglider cord operation device that is equipped with aerial spraying of agricultural chemicals and fertilizers, aerial photography equipment, and the like, and is operated by remote control from the ground.

[0002]

[Prior Art]

 Generally, in the case of an aircraft having fixed wings, it is possible to mount a control device that changes the wing characteristics by changing the angle of attack with flaps and ailerons. In the case of paragliders that fly with parachute or canopy as umbrella bodies, it is difficult to mount control equipment such as fixed wings due to the mounting space and weight. Normally, in a paraglider that is remotely controlled by radio, the break cords (direction control ropes) attached to the left and right of the canopy (or parachute) are operated during flight to change the wind resistance received by deforming the canopy. Maneuver to turn and climb. For example, when turning to the right, pulling the right side break cord to increase the resistance on the right side of the canopy, reduce the speed on the right side of the canopy and change direction. When descending, pull both break cords to increase the resistance of the entire canopy.

[0003]

[Problems to be solved by the device]

 By the way, one of the problems with the wireless remote control of the break code is that the amount of break code pulled is relatively large in order to give the canopy the necessary amount of deformation during turning and ascent and descent. For example, in order to displace the canopy on one side by about 20% of the wing span, it is necessary to pull the break cord by about 15 m at maximum. Therefore, in an actual paraglider, a quick winding mechanism consisting of gears and pulleys may be mounted on the servo motor in order to quickly wind a large amount of break cord, but when such a device is mounted, the entire weight of the breaker is reduced. There is a problem that the manufacturing cost will increase. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a radio-controlled paraglider cord manipulating device that can quickly perform a breaking cord pulling operation with a simple device.

[0004]

[Means for Solving the Problems]

 The radio-controlled paraglider cord operating device according to the present invention comprises a device main body, one or more rotary drive sources carried by the main body of the device, and a base end portion connected to an output shaft of the rotary drive source at a predetermined angle range. It has a pulling lever that rotates inside and has a pulley at its tip, and a plurality of break cords that extend from the canopy and that are wound around the pulley and that have their ends locked to the device body. The break code is pulled through the pulley by transmitting and operating a remote control signal and rotating an arbitrary tow lever.

[0005]

[Action]

 A remote control signal is transmitted from the ground to the paraglider in flight. The rotary drive source receives this signal to operate, and the selected traction lever receives rotation from the output shaft of the rotary drive source and rotates within an angular range of, for example, 90 ° at maximum. The break cord whose end is locked by the tilt of the tow lever is pulled through the pulley, and the canopy deforms according to the pulled length. The paraglider rotates or rises and falls due to the deformation of the canopy.

[0006]

【Example】

 Hereinafter, an embodiment of a radio-controlled paraglider cord operation device according to the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the material of the canopy 20 (umbrella) of the embodiment suppresses air permeability in order to have characteristics as a flight wing, and is made of, for example, a polyester-based, nylon-based or polyethylene-based synthetic resin. A cloth such as a woven cloth of a material or a woven cloth of natural fibers is suitable. The canopy 20 manufactured in a plane triangle or in a rectangular shape as in the embodiment is partitioned by a plurality of air-filled chambers (referred to as reams) 23a, 23b. The canopy 20 has a wing width of 2000 mm and a chord of 600 mm, for example.

The line cords 21 (suspension supporting cords) and the break cords 22 extend from the boundaries of the respective reams 23 a, and the same number of bilateral symmetry is distributed from the center of the canopy 20. For example, four sets of break cords 22 are provided on the left and right of the canopy 20 and at the rear. The cord terminal together with the line cord 21 is connected to a device body 10 such as a spraying unit for dropping pesticides or fertilizers in the air, or an aerial photographing unit. The equipment body 10 is equipped with a small engine of, for example, about 0.5 horsepower, can rotate a propeller 11 to obtain a flight thrust, and is also equipped with wheels 12 for takeoff and landing.

As shown in FIG. 3, a cord operating device 30 is provided on the device body 10 side. The device 30 has a servo motor (rotational drive source) 31, and a pulling lever 32 having a length of about 50 mm is connected to an output shaft 31a of the servo motor 31 and can rotate in an angle range of 90 °, for example. Is. The torque of the servo motor 31 is, for example, 1.9 kg m. A pulley 33 is rotatably supported on the tip of the tow lever 32. The end of the break cord 22 is wound around the pulley 33 in the form of a moving pulley, and the wound cord end is attached by a cord stopper 34. It is locked. The device 30 may have a configuration in which two break cords 22a and 22b corresponding to the left and right are operated or one left and right break cords 22a and 22b are operated. When the number of devices 30 is one or two, the motor output shaft 31a is connected to one or more pulling levers 32. In the case of a plurality of traction levers 32, it is necessary to operate each of the traction levers 32 individually or simultaneously, so that a switching mechanism for transmitting the rotation of the servo motor 31 to the selected traction lever 32 is provided.

The following is an example of how a paraglider is maneuvering during flight. When two cord operating devices 30 are installed corresponding to the break cords 22a and 22b which are distributed to the left and right, and only the device 30 on the left side of the figure is operated to turn the paragliter, the paraglider in flight is grounded from the ground. The remote control signal is transmitted. The servo motor 31 receives this signal to operate, and the traction lever 32 selected from the home position as shown in FIG. 3 receives rotation from the motor output shaft 31a and rotates clockwise in an angular range of, for example, 90 ° at the maximum. Rotate with. The break cords 22 (a, b) whose ends are locked by the cord stopper 34 are pulled by the fall of the tow lever 32, and the canopy 20 is deformed corresponding to the pulled length. The paraglider rotates due to the deformation of the canopy 20.

In the embodiment, the pulley 33 is attached to the tip of the traction lever 32 as a “moving pulley”. Instead of the pulley 33, a fixed fulcrum that does not rotate may be provided at the tip of the traction lever 32, the break cord 22 may be wound around this fixed fulcrum, and the traction lever 32 may be tilted and pulled. However, the pulling amount (length) of the break cord 22 pulled by the pulley 33 as a moving pulley is almost twice as large as when pulling through the fixed fulcrum. That is, in the case of a fixed fulcrum, the length of the traction lever 32 needs to be approximately doubled in order to obtain the same pulling amount as the pulley 33. It is clear that the pulley 33 is more advantageous than the fixed fulcrum when the restrictions such as the mounting space are taken into consideration.

[00011]

[Effect of the device]

 As described above, the radio-controlled paraglider cord operating device according to the present invention does not require a complicated cord operating mechanism for quickly winding a break cord, and does not require an output shaft of a rotary drive source such as a servo motor. A simple device equipped with a link-shaped pulling lever and a pulley that acts as a moving pulley at the tip of the device allows the break code to be pulled quickly and with a large pulling amount, which does not restrict the installation space and is low cost. It can be manufactured with.
