| 61 | Shovel | US937855 | 1978-08-29 | US4198090A | 1980-04-15 | David Gutman |
| An improved shovel (10) which includes the standard longitudinally extending handle member (12) having a scoop member (14) and a gripping member (16) rigidly secured on opposing longitudinally displaced end sections. The shovel (10) includes an adjustable lever mechanism (30) which is releasably secured and movably displaceable in a direction substantially normal to a longitudinal direction (20) in relation to handle member (12). Adjustable lever mechanism (30) is adapted to interface at a fulcrum point (38) with a base surface (18) to rotationally activate scoop member (14) when material is to be removed from base surface (18). An adjustable grip mechanism (50) is releasably secured and movably displaceable with respect to the handle member (12) and extends above the handle member (12) for providing a secondary gripping portion for a user. | ||||||

| An auxiliary handle for long-handled implements such as shovels, rakes, mops, brooms, snow shovels, and the like and enabling the user to obtain extra leverage without excessively straining himself, is disclosed. The auxiliary handle includes a triangular frame having a pair of rods constituting the legs of the triangle and diverging from closely juxtaposed first ends to relatively widely spaced second ends, and a transverse member pivotally connected to the rods at their second ends to constitute the base of the triangle and having medial members for releasably clamping it to the main handle of such an implement. A hand grip is fixedly secured to the auxiliary handle rods at the apex of the triangular frame, and a rigid cross-brace bar, which may be medially foldable, is swivelly connected at one of its ends to the apex of the frame and is pivotally connected at its other end with members for releasably locking it to the main handle of the implement. The auxiliary handle can be easily adjusted to different positions along the implement handle, and the angular inclination of the triangular frame relative to the implement handle can be varied as desired by the user. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure. | ||||||
