摘要： An engine-driven brush cutter (100) equipped with a safety device (42) that includes an acceleration sensor unit (24) attached to a drive unit (4) in an aslant orientation such that a detection axis (DA) of the sensor unit (24) inclines by an angle (θ1) relative to the right-and-left direction (R-L) of the brush cutter (100). This inclined orientation of the detection axis (DA) contributes to lowering the sensitivity of the sensor unit (24) to impulses in the direction parallel to a moving direction of a cutting blade (40) operated by an operator at work.

摘要： An engine-driven brush cutter (100) equipped with a safety device (42) that includes an acceleration sensor unit (24) attached to a drive unit (4) in an aslant orientation such that a detection axis (DA) of the sensor unit (24) inclines by an angle (θ1) relative to the up-and-down direction (V) of the brush cutter (100). This inclined orientation of the detection axis (DA) contributes to lowering the sensitivity of the sensor unit (24) to engine vibration to which the safety device should not be sensitive so much.

摘要： A transparent plastic shield kit for hand-held weed trimmers of various designs is disclosed. The kit includes a substantially square, transparent, planar shield with a vertical U-shaped slot that divides its upper half in equal parts. Installed on a trimmer shaft by a clamp either with or without an extension arm between the clamp and the shield, the kit allows the trimmer operator to have a protected view of the trimmer cutting head in use, while giving the operator full-body protection from debris thrown by the cutting head.

摘要： Multiple embodiments of a string trimmer debris shield are disclosed. In one embodiment, an L-shaped bracket having a clamp at one end is fitted to a string trimmer so that the bracket may be located to either side of a string head of the trimmer and either above or below a mounting point of the bracket. The bracket is mounted to the shaft near the rotating string, and supports a debris shield between a side of the string head from which debris is shown and legs and feet of a user. In another embodiment the bracket extends horizontally straight from the shaft to either side of the trimmer, and supports a debris shield. In a third embodiment the bracket is mounted to a shaft of a string trimmer and supports a perpendicular debris shield support member which in turn supports a debris shield on a side of the string head from which debris is thrown toward the user. In this embodiment, the debris shield may be rotated about the shaft to either side of the trimmer.

摘要： A string trimmer equipped with a knife and deflector apparatus mounted on the shroud directs cut debris laterally away from a workperson operating the string trimmer. A knife cutting edge located below the shroud cuts vegetation moved by the revolving string into cut debris. An upwardly extended radial deflector mounted on the shroud directs the cut debris laterally away from the shroud and workperson.

摘要： A collapsible protective shield assembly for grass and weed trimmers can be mounted on conventional grass and weed trimmers to keep debris from reaching the operator. When open, the shield assembly can be adjusted to enable the trimmer to get into hard to reach places. When not in use, the shield assembly can be collapsed into a compact configuration for easy storage. The shield assembly is mounted on the trimmer shaft a sufficient distance away from the trimmer cutting head to allow unobstructed operation of the trimmer.

摘要： The present invention provides for an article and method for an improved weed trimmer cover that prevents unwanted projectile and debris distributions. A preferred embodiment of the weed trimmer comprises a domed guard structure that encompasses the effective cutting range of a prior art weed trimmer. Alternative embodiments may comprise elements that protect only portions of front, side and rear cutting areas. Embodiments of the invention also allow a user to lift up a cover element to allow close work among obstructions. Embodiments of the present invention also improve the performance of prior art weed trimmers by increasing cutting performance and preventing flexible materials from wrapping about the cutting elements and shafts.

摘要： A string trimmer having an elongate shaft, a cutting head rotatably mounted on one end of the elongate shaft, at least one cutting member which extends from the cutting head, and a barrier which is capable of being used by an operator to move vegetation away from a path swept out by the cutting member when it rotates. The barrier is in the shape of a truncated sphere, and forms a broad band. There is further provided a guard on the string trimmer mounted on the elongate shaft which surrounds part of the rear of the path swept out by the cutting member as it rotates, wherein the barrier is mounted on the guard.

摘要： A cutting blade safety cover for covering a rear portion of a cutting blade of a portable trimmer. The safety cover includes a roof plate portion and a skirt portion suspended from the roof plate portion. The roof plate portion is separated at a radially middle location thereof into a radially inner portion and a radially outer portion. The radially inner portion and the radially outer portion are detachably attached to each other so that the radially outer portion is replaceable with another radially outer portion having a dimension suitable for covering a cutting blade of a different dimension.
