Abstract:
Described is a spring mechanism. The spring mechanism includes a leaf spring housing with leaf springs radially disposed within the leaf spring housing. The leaf springs being flexible between a rest state and tension state. A winding mechanism is engaged with the leaf springs for causing the leaf springs to flex from the rest state to the tension state. The winding mechanism includes a pushing pin wheel with a plurality of pushing pins protruding therefrom that rest against the leaf springs. The pushing pin wheel is rotatable such that rotation of the pushing pin wheel causes the leaf springs to flex from the rest state to a tension state. Release of the tension (i.e., when the leaf springs return to the rest state from the tension state) causes rotation of the leaf spring housing, which causes rotation of a corresponding release gear set and output drive.
Abstract:
An energy capture system includes a transducer element and an energy storage device. The transducer element moves in response to current in one or more conductors in a set of electrical power lines. The energy storage device accumulates mechanical energy from movement of the transducer element.

Abstract:
A spring motor for driving a driving shaft, comprising a spring operating gear; a spring about a rotation axis; a gear train; and a coupling arm connecting the rotation axis to the driving shaft by the gear train to transmit energy released by the spring from the rotation axis to the driving shaft, activating the driving shaft into rotation at a first speed. This spring motor allows storing energy in a spring; transmitting the stored energy to a driving shaft by linking an axis of the spring to the driving shaft by engaging the gear train; and reloading the spring; and reloading the spring by using a motor or transmitting energy from the driving shaft to the spring.
Abstract:
An automatic hinge module and apparatus for opening and closing a toilet bowl. The module includes: a motor, which generates a driving force; a housing, of which one end is coupled to a body of the motor; a drive shaft, which is rotatably coupled to the housing, and which has one end coupled to an output shaft of the motor, such that the centers of rotation of the drive shaft and the output shaft coincide, to allow the drive shaft to transfer the driving force to the exterior; and a spring, one end of which is coupled to the housing, and the other end of which is coupled to the drive shaft, such that the spring provides an elastic force to the drive shaft in a direction of rotation of the drive shaft. Using this module, the cover and seat of a toilet can be opened and closed automatically.
Abstract:
The electro-mechanical drive includes an electric motor, a transmission and a restoring spring. To improve the capacity to close the door, particularly in the event of a power failure, a large coil spring used as the restoring spring surrounds the electric motor and transmission. The electric motor is short circuited when not powered in order to create a generator effect with consequent damping during movement of the door.
Abstract:
Tensioning device for the energy store of an electrical switch, the energy store including a drive spring and the switch having a turn-on lock provided with a blocking latch of the turn-on lock of the switch, the device including:a rotatable drive shaft having a crank articulated to the drive spring, the drive shaft being rotatable into an end position at which the spring is tensioned and the drive shaft is supported at the blocking latch;a rotatable tensioning shaft and a displacement-producing mechanism carried by the tensioning shaft;a directional coupling device disposed on the drive shaft and coupled to the displacement-producing mechanism for rotating the drive shaft in steps in a selected direction in repsonse to rotation of the tensioning shaft;a spring member disposed for maintaining the coupling operative engagement with the displacement-producing mechanism;a setting member associated with the drive shaft for uncoupling the directional coupling device from the displacement-producing mechanism when the drive shaft is in its end position; andan additional energy source which is charged before the drive shaft reaches its end position and which is connected to hold the setting member in a position to maintain the directional coupling device uncoupled from the displacement-producing mechanism.
Abstract:
An improved spring wound prime mover capable of use with toys is provided. A plastic resin housing member comprises a pair of housing shells having complementary locking pawls and keeper members to permit a snap together assembly. The housing member further supports a spring member that can be selectively connected to a gear train assembly having a first and second gear ratio. The first gear ratio includes gears with a higher degree of mechanical strength than those engaged in the second gear ratio whereby a durable gear transmission is provided that can run smooth for driving the vehicle.
Abstract:
A child's electric swing includes a pre-wound wind-up mechanical escapement type motor having spring-biased retainer and driving pawls, the latter being connected to a pivotally mounted hanger supporting the swing seat. The pawls engage a mainspring-driven ratchet wheel which periodically impulses the driving pawl to maintain the seat in oscillation. The mainspring is rewound periodically by rotating the ratchet wheel in the opposite direction by a battery-operated motor through a gravity-operated one-way clutch after the ratchet wheel rotates only about 180.degree. so that the prewound spring is always under tension. Also the pawls are moved out of engagement with the wheel during such rewinding to eliminate noise and drag on the wheel.
Abstract:
A prewound retractor spring housing assembly for mounting to a preassembled safety belt retractor having a storage reel shaft end protruding from a side wall of the retractor, the shaft end having a retraction spring end receiving slot, has a spring mounting base means for receiving a retractor coil spring to be prewound thereon, spring cup means for encompassing the coil spring when prewound on the base means and for cooperating with the base means to prewind the spring to a desired prewound condition, means for locking the cup means to the base means and means for mounting the assembly to the safety belt retractor in a manner to automatically place the prewound spring in biasing relation to the safety belt reel.
