  • Patent number: 7407015
    Abstract: A safety mechanism for a hedge trimmer is disclosed. Thumb catches 1032, 1048, together with corresponding locking members are initially biased downwardly relative to corresponding actuator levers 1010, 1014, as a result of which actuation of a motor of the hedge trimmer is prevented. This prevents inadvertent one-handed actuation of the hedge trimmer. In order to actuate the hedge trimmer, the user holds one of the actuator levers 1010, 1014 the corresponding thumb catch 1032 or 1048 upwardly, which causes movement of the other thumb catch towards its release position to allow pivotable movement of the actuator levers 1010, 1014 relative to a handle of the hedge trimmer. Movement of one of the actuator levers 1010, 1014 relative to the handle brings the lever 1018 into engagement with the electrical switch assembly 1008 to actuate the motor of the hedge trimmer.

  • Patent number: 7360311
    Abstract: A drive mechanism for a power tool having a housing, a motor, and an output shaft moving in a reciprocating motion. The drive mechanism comprises a gear plate (34) adapted to rotate about a first axis (Z-Z) and having a plurality of elongate first teeth (33) extending perpendicular to the first axis; and a drive conversion mechanism cooperating with the gear plate (34) to cause reciprocating movement of the output shaft in response to rotation of the gear plate about the first axis. Conventional drive mechanisms having an output shaft with a reciprocating motion generally have bevel gears with teeth formed at 45° to the axis of rotation of the gears. By providing a gear plate and a drive conversion mechanism which provides a reciprocating drive force for an output shaft with teeth formed at 90° to the axis of rotation of the gear, the gear is cheaper and easier to make as the gear teeth do not have to be formed as accurately as prior art inclined gear teeth.

  • Patent number: 6826837
    Abstract: A sleeve for surrounding a power cord, in whole or in part, for appliances such as hedge trimmers. The sleeve, preferably composed of a lightweight polymeric material in corrugated, convoluted, or similar form, has relatively large radial dimensions compared to the cord and therefore resists the insertion of the sleeve and the cord into appliances (such as a hedge trimmers cutting blades) thereby preventing damage to the sleeve and the cord and preventing other undesired results. The relatively large size of the sleeve tends to increase the user's awareness of the sleeve and cord. Also the sleeve's increased rigidity compared to the cord aids in preventing the cord from being entangled in the appliance and assists in managing and manipulating the cord. The sleeve includes at least one aperture to facilitate the dissipation of heat generated by the power cord.

  • Publication number: 20030192186
    Abstract: A vibrator motor has a stationary piece and a moving piece hinged at one end. The moving piece does not generate substantial internal spring forces under the influence of an electromagnetic field, because it does not have a tail bracket. Other parts of conventional motors are also eliminated, so the motor is easier and less expensive to manufacture. In addition, the motor can be assembled and tuned before installation, which increases the ability to automate assembly.

  • Publication number: 20030041461
    Abstract: A sleeve for surrounding a power cord, in whole or in part, for appliances such as hedge trimmers. The sleeve, preferably composed of a lightweight polymeric material in corrugated, convoluted, or similar form, has relatively large radial dimensions compared to the cord and therefore resists the insertion of the sleeve and the cord into appliances (such as a hedge trimmer's cutting blades) thereby preventing damage to the sleeve and the cord and preventing other undesired results. The sleeve is tough enough to resist damage to the cord from cutting tools such as electric chain saws during incidental contact. In addition, the relatively large size of the sleeve tends to increase the user's awareness of the sleeve and cord. Also the sleeve's increased rigidity compared to the cord aids in preventing the cord from being entangled in the appliance and assists in managing and manipulating the cord.
