Rotating and / or extending hand-driven tool and associated systems and methods
View Patent ↗The disclosed apparatus, systems and methods relate to an improved extendable and rotatable shovel for use in various applications such as the shoveling of snow. Users can modify the shovel to accommodate their stature and personal preferences. The shovel is selectively rotatable and extendable, so as to be capable of a range of acute driving positions, such that a user can position the handle on or at the shoulder of the user in an upright driving position.
1. A drivable, ergonomic handheld shovel, comprising:
a. a telescoping elongate shaft comprising:
i. a proximal tubular portion having a proximal end;
ii. a distal tubular portion having a distal end; and
iii. a plurality of openings defined in the telescoping elongate shaft that are constructed and arranged to accept detents to secure the elongate shaft in a plurality of positions;
b. a shovel disposed at the distal end and defining a tool axis; and
c. a D-plus grip disposed at the proximal end and defining a handle axis, the D-plus grip comprising first and second side members and an end member disposed triangularly and angled ergonomic ends configured to cradle the shoulder of a user,
wherein:
a. the telescoping elongate shaft is constructed and arranged for:
i. selective, locking rotation relative to the handle axis, and
ii. selective, locking extension, such that the handle axis and tool axis can be selectively locked into parallel and perpendicular orientations, at a range of acute driving angles from the ground such that the D-plus grip is positionable adjacent to the shoulder of an upright user while maintaining an acute driving angle.
2. The tool of claim 1 , wherein the D-plus grip side members and end member define a handle opening.
3. An extendable, rotatable ergonomic shovel, comprising:
a. an elongate, telescoping shaft having proximal and distal ends;
b. a rotatable D-plus grip comprising first and second side members and an end member disposed triangularly, the end member comprising first and second angled ergonomic ends adapted to cradle the shoulder of a user;
c. a rotating collar in locking communication with the grip; and
d. a shovel disposed at the distal shaft end,
wherein:
i. the grip can be selectively rotated and the elongate shaft can be extended to a range of acute driving angles relative to the shovel, and
ii. the first and second ergonomic ends are shaped and arranged to be positionable in an armpit of an upright user.
4. The shovel of claim 3 , wherein the rotating collar comprises internal threads.
5. The shovel of claim 3 , wherein the rotating collar is configured to be in linear communication with the elongate shaft via rotation of the rotating collar.
6. The shovel of claim 5 , wherein the rotating collar is configured to secure the grip in a fixed rotational position.
7. The shovel of claim 3 , comprising
a coupling portion adapted to be attached to an elongate shaft.
8. The shovel of claim 7 , wherein the rotating collar is configured to be in linear communication with the elongate shaft via rotation of the rotating collar.
9. The shovel of claim 8 , wherein the rotating collar is configured to secure the handle in a fixed rotational position.
10. The shovel of claim 7 , wherein the rotating collar and coupling portion are in rotational communication via threads.
11. The shovel of claim 3 , wherein the D-plus grip further comprises one or more projections constructed and arranged to selectively mate with shaft openings to secure the D-plus grip in various rotated positions.
