Abstract
A hand-held edger capable of suppressing wear of a cover without an increase in the number of parts. The hand-held edger comprises a main rod supported by an operator's hand; a gear case supported at one end portion of the main rod; a rotating blade connected to a gear in the gear case; a power unit mounted to the other end portion of the main rod, for driving the rotating blade via the gear in the gear case; a resin-made cover attached to a flange of the gear case, for covering the rotating blade; and a wheel supported by the cover, and an outer periphery of the flange is coplanar with the periphery of at least the lowermost portion of the cover or diametrically outwardly protruded therefrom.
Claims9
A hand-held edger comprising:
- a main rod configured to be supported by an operator's hand;
- a gear case supported at one end portion of the main rod, the gear case having a protruded portion;
- a rotating blade connected to an output shaft extending from the gear case;
- a power unit mounted to an opposite end portion of the main rod, the power unit being configured to drive the output shaft and the rotating blade;
- a resin-made cover coupled to the gear case, the cover at least partially covering the rotating blade, the cover having a boss portion for securing the cover to the gear case, the boss portion being formed so as to surround the output shaft, the boss portion including a lower portion positioned between the output shaft and a ground surface during use;
- and
- a wheel mounted to the cover, wherein
- the protruded portion of the gear case has an outer periphery that is coextensive with, or protruding relative to, an outer periphery of the lower portion of the boss portion.
A hand-held edger comprising:
- a main rod configured to be supported by an operator's hand;
- a gear case positioned at one end portion of the main rod;
- a rotating blade connected to and output shaft extending from the gear case;
- a power unit mounted to an opposite end portion of the main rod, the power unit being configured to drive the output shaft and rotating blade;
- a resin-made cover attached to the gear case, the cover being adapted to at least partially cover the rotating blade, the cover having a boss portion for securing the cover to the gear case, the boss portion being formed at a lower portion of the cover so as to surround the output shaft;
- and
- a wheel mounted to the cover;
- a metal reinforcement plate embedded in the cover, wherein,
- a lower periphery of the metal reinforcement plate is positioned adjacent an outer periphery of a lower portion of the boss portion.
A hand-held edger, comprising:
- a main rod having a power unit positioned adjacent a first end, the power unit being operatively connected to a gear case positioned adjacent a second end of the main rod, the gear case having an output shaft configured to drive a rotating blade;
- a cover coupled to the gear case, the cover being configured to at least partially cover the blade during rotation, a portion of the cover surrounding the output shaft, such that a lower portion of the cover is positioned intermediate the output shaft and a ground surface during operation;
- a wheel mounted to the cover, the wheel being configured to support the edger when placed against a ground surface, such that the lower portion of the cover is adjacent the ground surface during operation;
- and
- a flange positioned intermediate the gear case and cover, an outer periphery of the flange being formed to be coextensive with, or protruding relative to, an outer periphery of the lower portion of the cover.
