Abstract

PURPOSE:To prevent a shock being applied to a towing device and construct it small and light by solidly combining an engine with a transmission equipped with a centrifugal clutch, coupling the transmission side of an in-frame accommodated power unit with a frame, fitted with a guide pulley, through a spring for sensing the tension, the thereby towing the object towed with a constant towing force. CONSTITUTION:An engine 11 and transmission 12 of a power unit 10 are coupled together using a common case 13, and a takeup drum 15 is fixed to the output shaft 14 of this transmission 12, and a brake 16 is provided. With rotation of this drum 15 in the direction of arrow, a towing cable 8 is wound included downward, and with its reaction force a tension sensing spring 20 is compressed upward and senses the tension, while the towing cable is given an elasticity to relieve the shock applied to a flier F. Eventual variation of the relative position with the device proper due to gliding of a paraglider concerned does not disturb application of a constant force to the paraglider because a caster type guide pulley 7 changes its direction while complying with the towing cable 8 in a wide range.

Paraglider P and flyer F are towed and glided. The towing speed is mainly controlled by operating the throttle lever <<-28, but it can be delicately controlled by operating the brake lever 27 while operating the brake 16. After the glider P ascends, the engine 11 is set to idle and the clutch 40 is made non-transmissive, so that the traction cable 8 is pulled out by the glider P and the winding drum I5 rotates in the opposite direction. Towing cable 8 at this time
The feeding speed is determined by the brake l6 with the brake lever 27.

These control methods are illustrated in the flowchart shown in FIG. That is, depending on the rotational speed of the engine, the torque applied to the winding drum 151 is reversed, causing the drum 15 to rotate forward or backward; however, in the case of forward rotation, the traction force of the traction cable 8 is controlled by the throttle lever 28 and brake lever 27. In case of reverse rotation, it is controlled only by the brake lever 27. The traction force required for the paraglider P to glide varies depending on the weight A or B as shown in FIG. 7, but it can be adjusted to an appropriate value by adjusting both levers 27 and 28. In addition, as shown in FIG.
It is also possible to adopt a method of controlling the engine rotation speed as feedback for La. Even if the position of the device changes as the glider glides, the caster-shaped guide boob 7 follows the traction cable 8 over a wide range and changes direction, making it possible to apply a constant traction force to the glider. can. Moreover, even if the traction tension suddenly changes due to a gust of wind or the like, the tension detection spring 20 expands and contracts to reduce the impact on the flyer F.
