BACKGROUND OF THE INVENTION
(a) Field of the Invention
The present invention is related to a self-running portable generator, and more particularly, to a new portable system for generating electricity.
(b) Description of the Prior Art
Portable electric power sources, e.g., generators, batteries, are indispensable in our daily life; however, so far all these Portable electric power sources must be dependent on other sources such as fuel or connection to a power source to recharge. Though batteries permit easy portability and convenient use, battery must be continuously replaced or recharged due to the limited storage capacity of the battery. As a result, these Portable electric power sources are not necessarily always readily available; and that could be a problem particularly for those who spend much time on the places with deficient electric supply. Also these power sources cannot be used at some distinct situation. To correct this problem, a new portable system for generating electricity is introduced.
Another problem with conventional concepts of power generation system is, most of the electric appliances and machines draw electricity from wall socket or main supply through a chord; this restricts their portability up to certain area, depending upon length of chord connecting appliance to the power supply socket.
In these respects the portable power system according to present invention substantially departs from conventional concepts of power generation system and in so doing provides a new device developed for the purpose of generating electricity. Furthermore, the present invention may be connected to any electric appliance or device to become another product with different application.
SUMMARY OF THE INVENTION
The general purpose of the present inventions are to provide a new self-running portable generator for uninterrupted power supply that has many novel features that result in a new power generation system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art power generation systems
The principle object of these inventions is to provide new portable devices to generate uninterrupted power supply, which can be used independently anywhere; wherein it can be made run by a part of its own generated electricity.
Another object of present inventions is to provide an independent power source, without continuous requirement of any external source for running and readily available for outdoor usage
The present inventions are not limited in its application and they are capable of other embodiments and of being practiced and carried out in various ways.
A self running portable generator comprising a crank, a gear transmission, a D.C. generator and a D.C. motor with coaxially coupled shafts or coaxially attached shafts. Wherein the crank is coupled to the gear transmission and the gear transmission is coupled to the motor and generator with coaxially coupled shafts or coaxially attached shafts, with a clutch gear.
The clutch gear is connected to a deflection shaft, which in turn is connected to a second shaft disposed in the gear transmission through a connection plate; and both ends of the deflection shaft are located in a deflection groove.
A single gear on the coaxially coupled shafts of motor and generator is attached upon the shaft and that gear engages with the clutch gear.
The gear transmission adopts a three-stage acceleration design to increase revolution speed for coaxially coupled shafts of motor and generator and it includes a first transmission gear, a second double gear, a third double gear, and a fourth double gear; Wherein the first transmission gear is fixed to the crank.
The motor is driven by a part of electric power outputted by the generator, while the remaining power is for the appliances that are need to be powered by generator.
In the present invention, the crank is rotated manually by holding its handle attached at the end of arm to further drive the gear transmission and then the coaxially coupled shafts of generator and motor revolves as driven by the clutch gear to generate electric current. After rotating the crank, when the crank is released, the clutch gear is disengaged from the gear attached on the coaxially coupled shafts of motor and generator; however, With the revolutions provided by the gear transmission, the coaxially coupled shafts of motor and generator revolves for a while to generate power by generator and to start the motor simultaneously. Power generated by generator is sufficient to start the motor while the coaxially coupled shafts are rotating. Once the motor is started during the crank is rotated, motor drives the generator, and motor is driven by the power supplied by generator, while remaining power is for the appliances or small products(depending upon generator’s rated
power and also motor) that are need to be powered by generator; this cycle continues for generating uninterrupted power supply.
The second preferred embodiment of the present invention is more efficient due to low power consuming motor. In the second preferred embodiment of the present invention, the shafts of generator and motor are not coaxially coupled to each other and another gear transmission between generator’s shaft and motor’s shaft is provided, to transmit revolutions by motor to generator. Though this gear transmission consists of only two gears, a gear with smaller diameter is attached to motor's shaft while another gear with large diameter is attached to generator's shaft.
A motor produces a high number of revolutions which are more than sufficient number of revolutions required by a generator to generate its rated power; by usage of another gear transmission between motor and generator, with proper gear ratio, some of the surplus numbers of revolutions from shaft of D.C motor are utilized to enhance torque that ultimately leads to allow the usage of a low power consuming D.C motor
Alternatively, the gear transmission may be comprised of a first revolving gear and a second double gear; wherein the first revolving gear is connected to a shaft and the second double gear is connected to a second shaft; the first revolving gear is fixed to the crank; the first revolving gear engages With a pinion in the second double gear; and a gearwheel of the second double gear engages With the clutch gear.
The present invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the description and drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIGS. 1 and 2 for first preferred embodiment, a Self-running portable generator for uninterrupted power supply of the present invention is comprised of a crank 1, a gear transmission 2, a clutch gear 9, a D.C. motor 3 and a D.C. generator 4 with coaxially coupled shafts or with a common shaft 15 and a switch 18. Wherein, the gear transmission 2 is mounted in a box 16; the crank 1 is connected to an input end of the gear transmission 2 to drive the gear transmission 2; the clutch gear 9 is located at an output end of the gear transmission 2 and engages with the gear 10 attached on the common shaft 15 of motor 3 and generator 4 to drive the shaft 15 to generate Electric power by generator 4 for starting motor 3.
The first transmission gear 5 is fixed to the crank 1 for the crank 1 to directly drive the first transmission gear 5 to revolve shaft 15; the first transmission gear 5 engages with a pinion in the second double gear 6; a gearwheel of the second double gear 6 engages with a pinion in the third double gear 7; a gearwheel of the third double gear 7 engages with a pinion in the fourth double gear 8. And gearwheel of the fourth double gear 8 engages with the clutch gear 9 to further increase the revolution speed.The input revolution obtained by crank 1 is increased through the series transmission executed by the gear transmission 2
When crank 1 is rotated to further drive the gear transmission 2, the clutch gear 9 engages with the gear 10 attached on the common shaft 15 to drive both motor 3 and generator 4 simultaneously and generate power to drive motor 3. When the crank 1 is released, gear transmission 2 stops rotating and the force acting upward as produced by the fourth double gear 8 upon the clutch gear 9 also disappears and thus, the deflection shaft 14 is pushed downward and the clutch gear 9 disengages from the gear 10 attached on the common shaft 15; but the common shaft 15 of the motor 3 and generator 4 continues to revolve for generating power, this is owing to running motor which is started when the crank 1 is rotated.
A part of the output power of generator is send back to motor’s terminals 20 to drive motor 3 while remaining power at generator’s terminals is for the appliances or machines that are need to be powered by generator 4. When crank 1 is rotated, the motor 1 starts by power generated by generator 4, and continues to run the shaft 15 with receiving power. The motor 3 continues to revolve the common shaft 15 and getting the power form generator 4, it can be switched off by operating switch 18.
Referring to FIG. 3 and 4, the connection plate 11 holds the clutch gear 9 to prevent its axial angle from deflection and the clutch gear 9 connected to a deflection shaft 14 which is connected to the second shaft 13 in the gear transmission 2 through a connection plate 11. While both ends of the deflection shaft 14 are disposed in a deflection groove 17. When the crank 1 is rotated in clockwise direction to drive the gear transmission, the fourth double gear 8 rotates anticlockwise for its gearwheel to drive the clutch gear to revolve. Since the clutch gear 4 is situated in a non-fixation status, the fourth double gear 8 will drive the clutch gear to deflect clockwise for the clutch gear 9 to engage with the gear 10 attached on the common shaft 15 to drive both motor 3 and generator 4 simultaneously by revolving the common shaft 15.
referring to FIG. 5, 6, 7 and 8, In second preferred embodiments of present invention, the shafts of generator 4 and motor 3 are not coaxially coupled to each other and another gear transmission 27 between generator’s shaft 26 and motor’s shaft 25 is provided, to transmit revolutions by motor 3 to generator 4, though the gear transmission 27 consists of only two gears 23 and 24; the gear 23 with small diameter is attached on motor’s shaft engages with gear 24 attached on generator’s shaft 26 to enhance torque by a low power motor 3 by decreasing the revolution speed.
When crank 1 is manually rotated, an increased revolution speed is supplied to shafts 26 and 25 of generator 4 and motor 3 respectively, through gear transmission 2. The rotating shaft 26 of generator 4 leads to power generation. A part of generated power is send back to motor’s 3 terminals to drive motor 3, in this way both motor 3 and generator 4 starts simultaneously during the crank 1 is rotated. When the crank 1 is released, the force acting upward as produced by the fourth double gear 8 upon the clutch gear 9 also disappears and thus, deflection shaft 14 is pushed to downward which cause the clutch gear 9 to disengage from the gear 24
After the motor is started by generated power, the generator’s shaft 26 receives suitable number of rotations through gear transmission 27 and the generator 3 generates power, which is continuously supplied to motor’s 3 terminals to drive motor , while remaining power at terminals is for the appliances or machines that are need to be powered by generator 4.
The third and fourth preferred embodiments of present invention are same as first and second embodiments respectively, but the gear transmission 2 is different as shown in FIG.9 and 10.
In third and fourth preferred embodiment of the present invention as illustrated in FIG. 9 and 10, a gear transmission 2 is comprised of a first transmission gear 5 and a second double gear 6. Wherein, the first transmission gear 5 connected to a shaft 12; the second double gear 6 connected to a second shaft 13; the first transmission gear is fixed to a crank 1; and the first transmission gear 5 engages with a pinion in the second double gear 6. The gear transmission in the preferred embodiment delivers only a regular acceleration.
However, the electrical connection between generator’s and motor’s terminals as shown in drawings is illustrative only and changes may be made in specific construction for transmitting output electric power from generator to motor. Furthermore, the D.C. motor used in the present invention consumes less power than the output power of generator.
The quantity of gears to be provided in the present invention is not restricted and the quantity may be added or reduced as applicable.
