Abstract
A power apparatus in which a battery is connected to a dynamo to drive it as a motor and deliver energy to a spiral spring to wind-up the spring. When the spring has been wound to a particular degree a sensor disconnects the motor from the spring which now unwinds and delivers output power. A further sensor detects low charge state of the battery and during unwinding of the spring, some spring energy is delivered to the dynamo, now acting as an alternator, to charge the battery.
Claims18
A power apparatus comprising:
- electrical storing means for storing electrical energy;
- at least one unit for transformation and storage of energy comprising electromechanical means for transformation of said electrical energy from the electrical storing means into mechanical energy and for transforming mechanical energy into electrical energy, and
- spring means for storage of the mechanical energy as potential mechanical energy, said at least one unit being coupled with mechanical means for delivering said mechanical energy, said mechanical means including an inertia mass, said electromechanical means being constructed and arranged to deliver the mechanical energy to said spring means for delivery to said mechanical means and for receiving output from said spring means to supply electrical energy to said electrical storing means.
Apparatus for delivering power comprising
- a rechargeable battery,
- a control unit connected to said battery,
- a power unit connected to said control unit for delivering power output from said battery, said power unit comprising a dynamo operative as a motor and as an alternator,
- a switch connected between said control unit and said dynamo such that in one state the battery drives the dynamo as the motor while in a second state the dynamo acts as the alternator and charges the battery,
- a spring connected on a spring shaft, said spring in said one state storing mechanical energy delivered from said dynamo acting as the motor while in said second state the spring releases stored energy,
- an output shaft for delivering output power from said power unit,
- a gear transmission including a ratchet gear connecting said spring shaft and said output shaft so that in said second state said spring delivers mechanical energy to said output shaft while in said one state said spring receives said mechanical energy and free-wheels with respect to said output shaft,
- a transmission assembly between said spring and said dynamo for delivering said mechanical energy from said dynamo to said spring so that said spring operates in said one state to store the mechanical energy, said transmission assembly including a release mechanism connected to said control unit to interrupt delivery of mechanical energy from the dynamo to the spring in the second state thereof,
- a sensor connected to said battery to detect a charge state thereof, said sensor being connected to said control unit so that when a low charge state is detected in said battery, said transmission assembly is operated to drivingly connect said spring, when in said second state thereof, to said dynamo so that the dynamo is driven as the alterator to produce electrical energy which is supplied via said switch to charge said battery.
