摘要:
A tool with a driver (32) and a motor assembly (30) for selectively translating the driver along an axis. The driver has a driver blade (502) and a driver body (510) that is coupled the driver blade. The driver body can be formed of titanium and can include an engagement surface (590) with a plurality of teeth (600) that matingly engage respective teeth (360) that are formed on the edge of a flywheel (42) that is associated with the motor assembly.

A tool with a driver (32), a motor (40), a structure to which the motor is coupled and a return cord (1052) assembly. The driver that is translatable along an axis between an extended position and a retracted position. The motor is configured to translate the driver from the returned position to the extended position. The return cord assembly is coupled to the driver and the structure and includes a spring (1082) and an elastomeric return cord (1080) that are employed to return the driver from the extended position to the retracted position.

The invention relates to an actuating element (5) that is mounted on electrical appliances in such a way that it can pivot about a pivoting axis (19) in the switching direction of a switch, in order to switch a function of an electrical appliance (1) by actuating the switch (22), and comprises a slide (16) provided with an actuating surface (15) that is displaceably guided along a slide path (18) provided on the actuating element in order to adjust an operating parameter. The aim of the invention is to create an operating rocker/slide, enabling uniform forces to be introduced into the operating rocker during the displacement of the slide. To this end, the actuating element (5) is embodied in such a way that the slide path (18) and the pivoting axis (19) extend at least essentially parallel to each other. The parallel orientation of the pivoting axis and the slide path enables the same length of lever arm to be obtained in relation to the pivoting axis of the actuating element, in each position of the slide, during the introduction of forces into the actuating surface of the slide. As a result of one such constant lever arm, the regulation between the slide and the operating rocker can be carried out in an especially reliable manner.

A method for calibrating a power tool having a roller (852), a driver (32) and a solenoid (810,44). The solenoid has a body and a rod (820) and is coupled to the roller so as to be capable of selectively advancing the roller toward the driver. The method includes: locating the roller onto a predetermined portion of the driver; moving the body of the solenoid in a first direction until the occurrence of a first predetermined condition, the first direction being in a direction that causes the roller to be driven toward the driver; after the occurrence of the first predetermined condition, moving the body of the solenoid in a second direction opposite the first direction until the occurrence of a second predetermined condition and thereafter securing the body of the solenoid to inhibit further movement of the body of the solenoid.

A power tool with a flywheel (42), an activation arm (806), a driver (32), a cam and a clutch (800). The activation arm can have a first arm, a second arm, which can be pivotally mounted to the first arm, and a roller (808) that can be coupled to the second arm. The driver can be disposed between the roller and the flywheel. The cam can be moveable in a predetermined direction for causing the activation arm to rotate about a pivot to drive the roller against the driver so that the driver frictionally engages the flywheel. The clutch can cooperate with the cam to inhibit the cam from moving in a direction opposite the predetermined direction in response to a reaction force that is applied by the driver onto the activation arm.
