MULTIPURPOSE POWER GENERATING APPARATUS

Technical Field

[1] The present invention relates to a power transmission apparatus for transmitting power to a riding device by using organic dynamic relation of a pulley. More particularly, the present invention relates to a multipurpose power generating apparatus, which can be used as a power generating apparatus of a bicycle, a hang glider, and a generator, and comprises elements for transmitting power to a rotary shaft by the application of a kinetic force, such as a pair of symmetric pedals acting as leverages, a fixed pulley for converting the direction of a force, a rotary pulley for improving a force, and wires for connecting the above elements. Background Art

[2] In general, since the power generated by a conventional pedal is identical at the input side and the output side, when such pedal power is used in a bicycle, it is used re- strictively to exercise means for drilling a body and transporting means for reciprocating near distance. In particular, when an excessive load is applied from the burden loaded on the upper end of a rear wheel of a bicycle, the operator becomes easily tiresome due to increase of the treading force applied to the pedal.

[3] Accordingly, to solve such problems, there has been proposed a Korean utility model gazette No. 76-30 entitled with "A propulsion device for a bicycle", and a utility model gazette No. 81-2137, and the like. In other words, the former devise was to propel a large burden with small force by the rotation of an operation rod and a motored gear, and the like with using a principle of leverage by making the gear of the bicycle large, and the latter is to propel the upward and downward movement of the pedal of the bicycle by the pulley and a latch, and the like, which is mounted at the rear wheel shaft. However, there occur problems in that a shaft center is complicated, and the organic structure of the lever and the latch, and the like is complicated, thereby requiring high degree minuteness, and the manufacturing process is complicated, thereby reducing the economic efficiency.

[4] The present inventor has developed a multipurpose power generating apparatus to solve such conventional problems, and to provide a sky cycle for sufficiently empowering lifting force, and a wind force generator operating with small blades, by combining a pair of pedals acting as leverage, a fixed pulley for converting the direction of a force, a rotary pulley for improving a force, and wires for connecting the above elements, and the like into a frame, so that they can be operated in coupled relation to control the length of the wire, the size of the pulley, and the angle and the length of the pedal, according to their objects.

[78] Mode for the Invention

[79] Hereinafter, the preferred embodiments of the present invention will be described in detail with reference to the appended drawings.

[80] Embodiment 1

[81] The multipurpose power generating apparatus 1 of the present invention comprises, as shown in FIG. 1, largely a frame, a pulley, a wire, and a lever. In this regard, it should be noted that all of the pulley, the wire and the lever for rotating the pulley, except the frame, the rotation member, and the rotary pulley, are provided as one pair to correspond to each other.

[82] Also, identical elements are represented by identical numerals and repeated explanations thereabout will be omitted.

[83] The main frame 10 is made of round metal pipe, and is formed with securing portions 12, 12' at the front and rear end thereof. Also, the securing portions 12, 12' are formed with holes 12a, in which a bearing (not shown) is disposed, and a shaft 13 and a crank shaft 13' are disposed at the inside of the bearing. In addition, the shaft 13 is provided with a rotation member 20, and the crankshaft 13' is provided with a rotary pulley 80.

[84] Moreover, the rotation member 20 is provided with a first lever 30 at one side of the center upper end thereof and secured by welding means so that it diverges by a predetermined angle, and is provided with a second lever 30' and secured integrally by welding at a side opposite to the first lever 30 and is lower than a position where the first lever is installed. Pedals 31, 31' are also provided at one end of the first and second levers 30, 30' so that the operator can tread with his feet.

[85] Also, first and second support frames 40, 41 are formed integrally at a position adjacent to the main frame 10 to correspond to each other in a ladder shape, and a first auxiliary frame 43 is integrally formed at one end of the first support frame 40 and the main frame 10 in an in versed triangular shape.

[86] In this instance, securing pieces 45 are respectively provided at one end of the second auxiliary frame 41, the first frame 40, and the auxiliary frame 43 so that they can be secured and supported to the bottom. Also, a securing frame 42 is integrally formed between the first and second support frames 40, 41, and an elongate hole 42a is formed horizontally at the securing frame 42.

[87] In addition, the first and second support frames 40, 41 are formed with first and second securing shafts 40a, 41a opposing to each other at both sides thereof, and first and second rotary shafts 40b, 41b are formed fixedly at the lower side of the securing shafts.

[88] Also, a third securing shaft 42b is formed at one side of the elongate hole 42a formed at the securing frame 42, and a movable shaft 42c is installed and secured in the elongate hole 42a elastically by a spring S.

[89] In addition, a first pulley 60 is rotatably installed at the third securing shaft 42b, which is formed at both sides of the securing frame 42 constructed as above, and a second pulley 61 is rotatably installed at the movable shaft 42c.

[90] In this instance, each of guide pulleys 70, 71 is rotatably provided at the first rotary shaft 40b, 41b formed at the first and second support frames 40, 41.

[91] Accordingly, a first wire Wl mounted to the first pulley 60 is secured at one end thereof to the first securing shaft 40a, and is secured at the other end thereof to the rotation member 20 via the first pulley and the first guide pulley 70 installed to the first rotary shaft 40b. Also, the second wire W2 mounted to the second pulley 61, which is provided at the movable shaft 42c disposed at both sides of the securing frame 42 to oppose to each other, is secured at one end thereof to the second securing shaft 41a, and is integrally secured at the other end thereof to both ends of the crank shaft 13' disposed at rear side of the main frame 10 via the second pulley 61 and the second guide pulley 71 mounted to the second rotary shaft 41b. In addition, a third wire W3 is mounted between the third securing shaft 42b and the movable shaft 42c provided at the securing frame 42 with predetermined interval there-between.

[92] Therefore, in the multipurpose power generating apparatus 1 as constructed above, when the pedal 31 is treaded, it functions as a lever so far as it is bent and as long as the length of the lever, thereby producing a large force from a small force to draw the rotation member 20 forward, result in the drawing of the first pulley 60. In this instance, the requiring drawing force is reduced to half of its original force by means of a principle of the first pulley 60. Then, the second pulley 61 is drawn by the half reduced force again, thereby also reducing the required force.

[93] In this instance, as the first wire wl is secured to the first securing shaft 40a, the first pulley 60 is rotated as long as the moving distance of the lever 30, thereby concurrently rotating the second pulley 61 installed to the movable shaft 42b.

[94] In other words, if the second pulley 61 moves toward the first pulley 60 to draw a crank shroud 81a formed integrally with the crank shaft 61 when one end of the second wire w2 is secured to the second securing shaft 41a, and the drawing force is converted into rotation movement to rotate the rotary pulley 80, and the rotation movement can be applied to wheels of a bicycle, a generator, and an electric fan, which have several shafts P connected to a belt V.

[95] Thus, the application direction of the force reduced several times of its required force is converted by using the guide pulleys 70, 71, which are installed a little lower than the center point of the rotary pulley 80 to draw the crank shroud 81a to the lower side. In this instance, the required force can be further reduced by the application of the principle of a slope. Thus, the transferred reduced force rotates the crank shroud 81a, and the force finally rotates the respective available shaft P.

[98] Herein, the power transmission device 90 comprises a blade 91 rotated by wind force, a first gear box 92 connected to a shaft of the blade, a main shaft 93 rotated by the first gear box, and a second gear box 94 for transmitting the rotation force of the main shaft to a pair of levers 30, 30'.

[125] Then, at the state as described above, the rider puts back the backrest 131 of the seat at the time of high speed operation (confer FIG. 7).

[126] Next, if the rider holds the handle 4 and treads right and left pedals alternately in the direction "a" shown in FIG. 4 when he rides the bicycle, the torque transmission bar 170 installed integrally with the pedal bundle 160, becomes to rise in the direction of "b" thereby drawing the first wires Wl, Wl' in the direction c by the rising of the torque transmission bar 170.

[127] Then, the first wires Wl, Wl' draw the first and the second movable pulleys 200,

210 via the rotary pulleys 180. In this instance, since the first wires Wl, Wl' are secured to the securing portion 230, the first and the second movable pulleys 200, 210 progresses in the direction of the arrow "d" along the elongate hole 191 formed at the support bracket 190 and rotate in the direction "d" instantly. Then, the rotation force draws the second wires W2, W2' installed at the rear wheel 3 in the direction of the arrow "e", and the crank gear 260 is rotated by the drawing force in the direction of "f". Then, the rotation force is transmitted to the gear G installed at the rear wheel via the chain C, thereby progressing the rear wheel, result in the driving of the bicycle.

[128] Undoubtedly, while the present invention has been described with regard to one direction so far, the present invention can be explained with regard to the opposite direction identically.

[129] In this instance, the crank rotation bar 260 rotates by 180° by the drawing of the second wire W2, and as the other second wire W2' rotates by 180°, so that the crank rotation bar 261 secured to the second wire W2 is returned to its original state in order, thus repeating the operations to move the rear wheel forward.

[130] Meanwhile, when the rider rotates the handle to the right or to the left at the driving state as described above, the steering bars 150 installed at both lower sides of the handle securing rotary shaft 140 and both sides of the front fork 120 move the front wheel 2 to the right or left direction, result in the converting of the direction. Industrial Applicability

[131] As described above, according to the multipurpose power generating apparatus of the present invention, it is possible to make the bicycle with quick speed, the sky cycle with enough lifting force, and the wind power generator, and the like into realization by adjusting the length of the wire, the size of the pulley, and the length and angle of the pedal according to the applications.

[132] Thus, the restricted use of the bicycle is solved by the improved action and effect of the present invention, and the bicycle was made to be an important transportation means to contribute to the saving of the energy and environmental protection, in addition to the drastic change about the traffic policy.

[133] Also, if the present invention is applied to the sky cycle, it will be used advantageously as novel transportation means and contribute to the bringing up of the leisure industry, and if the present invention is applied to the wind power generator, it is possible to contribute to the energy saving and the environmental protection because the size of the blade can be drastically reduced, thereby making it possible to mass produce the household wind force generator with low price and good capacity.

[134] Also, it is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention, and such modifications are wholly pertained to scope of the appending claims.
