  • Patent number: 11369057
    Abstract: The invention is directed to an outdoor device, preferably a string trimmer, having a hinged pole for folding the string trimmer. The hinge has an easy to use lock that allows for repeated folding of the trimmer for easy transport and storage. The string trimmer has a battery at a rear end of the pole near the handle, and a motor at a front end on the cutting head. An electrical cable is run from the battery to the motor to provide power to the motor. The hinge provides a protective sheath around the cable to protect it from damage when the string trimmer is folded and the cable might otherwise be exposed. Additionally, the string trimmer includes a guard around the cutting head that contacts a battery housing to secure the string trimmer in a folded position.

  • Patent number: 10694672
    Abstract: Systems and methods for using interchangeable tool attachments in multi-use tools. In one embodiment, a multi-use tool includes a motor, a shaft and a shaft adapter at the end of the shaft. The motor has user controls (e.g., on/off switch or throttle) that control the motor to drive the shaft and cause it to rotate. The shaft may include a rigid tubular outer member with a flexible inner shaft. The shaft adapter is coupled to the end of the rotating portion of the shaft. The shaft adapter has a mounting flange that rotates with the adapter at the end of the shaft. An interchangeable tool attachment is secured to the mounting flange, and rotation of the shaft adapter and mounting flange causes the tool attachment to rotate as well. Many different tool attachments can be interchangeably secured to the mounting flange to provide corresponding, different functions to the tool.

  • Patent number: 7302871
    Abstract: The invention relates to an oscillation generating device for use in a soil compacter with a tipping moment compensation device. A second unbalance shaft pair with oppositely rotating unbalance shafts is arranged adjacent to a first unbalance shaft pair as a tipping moment compensation device. Diagonally opposite unbalance shafts rotate in the same direction. In this way, centrifugal forces and torques on the two unbalance shaft pairs reciprocally cancel each other out so that no tipping moment occurs parallel to the axes of rotation of the unbalances.

  • Patent number: 6997268
    Abstract: A trimmer comprises a cutting head (1) housing a cutter (5), and a shaft (2) for supporting the cutting head. A large diameter wheel (8) is rotatably mounted with respect to the cutting head (1), and a motor is provided for driving the cutter (5) via an output shaft (7). The cutting head (1) is connected to the shaft (2) by a joint (3) permitting the cutting head (1) to be positioned with its cutter (5) either substantially horizontal or substantially vertical. The wheel (8) is sized to contact the ground when the cutter (5) is substantially vertical and to circumscribed the axis of the output shaft (7). The arrangement is such that the cutter (5) extends beyond the circumference of the wheel (8).

  • Patent number: 6968906
    Abstract: An electric tilling machine has a motor mounted on a machine body for rotationally driving a tilling shaft provided with tilling claws. A housing/cleaning box has an upper opening and is configured to receive therein the tilling shaft and tilling claws with the machine body closing the opening of the box. Front and rear locking sections lock the machine body to the housing/cleaning box with the tilling shaft and tilling claws housed in the box. A control section keeps the motor in a controllably operable condition while the machine body is locked in the housing/cleaning box so that the motor can be operated to rotate the tilling shaft and tilling claws within the box in a cleaning mode.

  • Patent number: 6955227
    Abstract: An auger to assist in ground-burrowing or mixing paint or concrete, is used by attaching it to an electric or cordless power source. The major advantages over previous augers are: a hex head design prevents slipping in the drill chuck, an offset boring tip provides better digging, and a removable extension allows for the digging holes from a sitting or standing position possible without straining. The cutting edge of the auger's discs is sharpened for easier digging in hard soil. A single spring pin lock connects a first shaft to the extension shaft.

  • Patent number: 6766866
    Abstract: A tiller includes an engine, a transmission mechanism, and a rotor shaft having tillage tines mounted thereon. The transmission mechanism transmits a motive power of the engine to the rotor shaft to thereby cause the tillage tines to perform a tilling operation. The tiller also includes a tranmission case having the transmission mechanism housed therein, and a fender disposed to cover the tillage tines. The fender is mounted to the tranmission case by bolts. Each bolt has a portion projecting downwardly from the fender. The tiller further includes a guard member extending downwardly from the transmission case to a level lower than the downwardly projecting portion of each bolt. The guard member guards the bolts against a foreign object thrown upwardly by the tillage tines during the tilling operation.
