074047000 | Crank and lever | 13 |
20090151484 | Folding crank handle for hose reel - A crank assembly having a crank arm with a handle member pivotally coupled thereto is provided. The handle member includes a lock assembly with a crank component and a handle component. The crank component includes a latch surface on a crank arm outer surface. The lock assembly handle component is, preferably, at least one extension extending from the handle member and structured to engage the latch surface. The lock assembly handle component further has a release device structured to disengage the at least one extension from the latch surface. The release device is accessible from the crank arm outer surface. In this configuration, a user may easily access the release device because the release device is located on the outer surface of the crank arm. | 06-18-2009 |
20090193914 | Torque Transfer Device - A torque transfer device for efficiently increasing the torque transferred from a drive unit to another device (e.g. transmission, sprocket, etc.). The torque transfer device generally includes a drive unit, a first rotating member rotatably attached to the drive unit, wherein the drive unit rotates the first rotating member, a receiving unit, a first rotating member rotatably attached to the receiving unit and a connecting arm attached to a first attachment point of the first rotating member and a second attachment point of the second rotating member. The first attachment point is offset from a first rotational axis of the first rotating member and the second attachment point is offset from a second rotational axis of the second rotating member. | 08-06-2009 |
20090272208 | WINDOW WIPER SYSTEM WITH A WINDOW WIPER DRIVE, IN PARTICULAR FOR A REAR WINDOW WIPER OF A MOTOR VEHICLE WITH A GEAR ARRANGEMENT WHICH CAN BE EXCHANGED IN A MODULAR MANNER - The invention relates to a window wiper system with a window wiper drive ( | 11-05-2009 |
20110000327 | Linear Kinetic Energy to Rotational Kinetic Energy Converter - An energy conversion system that converts linear kinetic energy to rotational kinetic energy is disclosed. A force is applied to a coil spring, compressing the spring. The spring drives an arm forward as the spring returns to its uncompressed state. The arm, in turn, causes the driving portion of an over-running clutch to rotate forward and drive an output shaft. The linear motion of the arm being driven forward by the spring is converted to rotational kinetic energy in the output shaft. The output shaft may then be connected to an external device to drive that device. | 01-06-2011 |
20120042739 | SYSTEMS FOR TRANSMITTING DRIVE FORCE - The disclosure provides new crankshaft configurations for various purposes. In one embodiment, new crankshaft configurations are provided that are believed to be particularly suitable with internal combustion engines. Exemplary mechanisms convert a linear sinusoidal motion to a rotational one. In another embodiment, new crankshaft configurations are provided that are believed to be particularly suitable with manually operated drive systems, such as on bicycles. Exemplary mechanisms convert elliptic or linear reciprocating motion into angular motion. | 02-23-2012 |
20120272757 | DRIVE DEVICE IN A WINDSHIELD WIPER UNIT OF A VEHICLE - A drive device in a windshield wiper unit comprises a crank arm ( | 11-01-2012 |
20130125679 | KITCHEN APPLIANCE - A kitchen appliance includes a base body, a pivot arm which is disposed in a pivotable manner on the base body and a lever facility for assisting a pivoting movement of the pivot arm. An adjusting mechanism is operably connected to the lever facility to set a degree of assistance for the pivoting movement. | 05-23-2013 |
20130139620 | DRIVE UNIT - A drive unit includes an output shaft, a drive source, which causes the output shaft to rotate in a reciprocating manner within a first angular range, an arcuate movement portion, which performs arcuate movement about the axis of the output shaft as the shaft is rotated, a pivot shaft, and a lever member, which is rotational about the axis of the pivot shaft. As the arcuate movement portion performs arcuate movement, the lever member is rotated, in a reciprocating manner within a second angular range, while changing the engaging position with the arcuate movement portion. | 06-06-2013 |
20130199317 | DIRECT DRIVE FOR EXERCISE MACHINES - An exercise machine includes a support structure, a crank shaft rotatably mounted on the support structure, a first planetary gear set operatively coupled to the crank shaft so that the crank shaft provides an input for the first planetary gear set, a second planetary gear set operatively coupled to the first planetary gear set so that an output of the first planetary gear set provides an input for the second planetary gear set, and a flywheel rotatably operatively coupled to the second planetary gear set so that an output of the second planetary gear set rotates the flywheel. | 08-08-2013 |
20150020621 | ELECTRIC BICYCLE - An electric bicycle is provided that can increase the diameter of the joining section between a crankshaft and a crank arm, suppress an increase in manufacturing cost, and minimize a size increase of a hanger with a torque sensor disposed in the hanger. A crankshaft | 01-22-2015 |
20150082921 | Robotic Sign Waving Device - A robotic sign waver has a chassis including a main plate which mounts a drive train. The drive train includes a motor and a gearbox coupled to the motor. The gearbox has an output shaft that drives a crank arm with a linkage rod attached thereto. The linkage rod drives a rocker plate that is mounted on the main plate for repetitive motion. An elongated waving arm is mounted on the rocker plate for repetitive motion with the rocker plate. The rocker plate is robust to withstand the stress and wear of repetitive motion while the waving arm is relatively light to minimize its load on the drive train. A counterweight is attached to the rocker plate on the opposite side of the main plate from the rocker plate by means of connectors extending through slots in the main plate. A reversible connector plate allows attachment of the chassis to either vertical or angled sign boards. | 03-26-2015 |

20120216636 | ANTI-BACKLASH/ANTI-RATTLE LEVER - An anti-backlash assembly of the type for transferring motion via a pin movable along a slot. The assembly comprises a pivot lever and a second lever member. The pivot lever comprises a body portion and a pivot lever portion extending from the body portion to a pivot lever distal end. The pivot lever portion defines a pin engagement slot extending from adjacent the pivot lever distal end toward the body portion. A pair of fingers extend in parallel and spaced relationship from the pivot lever distal end of the pivot lever portion toward the body portion to engage opposite sides of a pin of the engagement arm. Each of the fingers includes a pin engaging section extending to an inwardly extending distal end and a spring section extending in a for urging the fingers into clamping engagement with the pin. | 08-30-2012 |
20130255409 | SPRAYER ACTIVATION DEVICE - The sprayer activation device contains a base member, a cover member, and a transmission assembly. The base member provides an accommodation space, an axle, a positioning piece, a through hole, and a number of positioning pins. The transmission assembly contains a motor and a number of engaging transmission gears in the accommodation space. The motor axle is threaded though the through hole of the base member and has an axle gear engaging a transmission gear. A pin is configured on another transmission gear. The cover member seals the accommodation space, and has a positioning pieces and a through slot. A crank is provided with a positioning opening and an axle hole at its two ends, and a hammer is configured at a side of the crank. The hammer is moved up and down as the transmission assembly drives the crank. | 10-03-2013 |
