发明名称 Shield assembly for a power tool
摘要 The present invention is directed toward a shield assembly for a handheld tool device such as an angle grinder. The shield assembly is selectively repositionable with respect to the cutting tool. A lock mechanism secures the shield assembly in discrete rotational positions relative to the cutting tool. The shield assembly includes a guard member and a bumper member, and an alignment feature configured to align the relative positions of guard member and the bumper member, thereby positing the members in a predetermined relative orientation. With this configuration, the shield assembly is selectively repositionable via a “hands-free” mechanism that permits a user to adjust the position of the shield assembly by simply contacting the shield assembly against a work surface.

主权项 1. A guard lock for a powered apparatus, the powered apparatus having a neck extending from a gear case, the guard lock comprising: a guard member, the guard member having a body portion for at least partially surrounding a working member of the power tool and a collar connected to and extending from the body portion, the collar including multiple windows that are spaced from one another, a stop lever coupled to the gear case via a fastener about which the stop lever may pivot, the stop lever including an engagement portion and a distant arm portion, the engagement portion including an angled surface and a straight surface, the fastener disposed between the engagement portion and the distal arm portion, and a biasing member for biasing the engagement portion of the stop lever toward a window of the collar, wherein when the engagement portion is positioned within a window, rotation of the collar is permitted in a direction of the angled surface but is prevented in a direction of the straight surface, and wherein a depression of the distal arm portion toward the collar pivots the engagement portion away from the window.
