Abstract

An ergonomic sweeping device that can be used with one hand while providing a user with proper biomechanical alignment and support, which can reduce muscular strain, fatigue, and the potential for injury.

Claims (32)

1. A tool, comprising:

an elongated member having a distal end and a proximal end and wherein an angled offset region delineates a proximal portion and a distal portion;

a handle with a grip portion coupled with the proximal portion of said elongated member and oriented such that the transverse midpoint of the grip portion is substantially aligned with the central longitudinal axis of the distal portion of said elongated member;

a forearm support coupled with the proximal portion of said elongated member and located superior to said handle and oriented in substantially linear alignment with said handle along an axis substantially parallel to the central longitudinal axis of said proximal portion of said elongated member; and

a pivoting connector coupled with said distal end of said elongated member, said pivoting connector having a range of rotational motion up to 90-degrees in each direction with respect to said distal end of said elongated member;

wherein said elongated member has an adjustable length and further comprises a length adjustment mechanism in said proximal portion of said elongated member between said handle and said forearm support.

2. The tool of claim 1 , further comprising a bristle assembly coupled with said pivoting connector.

3. The tool of claim 1 , wherein said elongated member has an adjustable length and further comprises a length adjustment mechanism in said distal portion of said elongated member.

4. The tool of claim 3 , wherein said length adjustment mechanism comprises a spring-loaded locking button device.

5. The tool of claim 1 , wherein said length adjustment mechanism comprises a spring-loaded locking button device.

6. A sweeping device, comprising:

an elongated member having a proximal portion, an offset portion, and a distal portion, said offset portion being coupled between said proximal portion and said distal portion and having a central longitudinal axis that is angled relative to said proximal portion's central longitudinal axis and said distal portion's central longitudinal axis;

a handle coupled with said proximal portion between said offset portion and a proximal end of said proximal portion, said handle having a grip with a transverse midpoint that is substantially aligned with said distal portion's central longitudinal axis;

a forearm support coupled with said proximal portion between said handle and said proximal end, said forearm support being oriented in substantially linear alignment with said handle along an axis substantially parallel to said proximal portion's central longitudinal axis; and

a bristle assembly pivotally coupled with a distal end of said distal portion;

wherein said proximal portion comprises an adjustment mechanism, said adjustment mechanism being configured to adjust the length of said proximal portion between said handle and said forearm support.

7. The sweeping device of claim 6 , wherein said forearm support is selectively rotatable relative to said elongated member.

8. The sweeping device of claim 6 , wherein said handle is selectively rotatable relative to said elongated member.

9. The sweeping device of claim 6 , wherein said distal portion comprises an adjustment mechanism configured to adjust the length of said elongated member.

10. The sweeping device of claim 9 , wherein said adjustment mechanism comprises a spring-loaded locking button device.

11. The sweeping device of claim 6 , wherein said adjustment mechanism comprises a spring-loaded locking button device.

12. The sweeping device of claim 6 , wherein said bristle assembly is selectively detachable from said distal end.

13. A tool, comprising:

an elongated member having a proximal portion, an offset portion, and a distal portion, said offset portion being coupled between said proximal portion and said distal portion and having a central longitudinal axis that is angled relative to said proximal portion's central longitudinal axis and said distal portion's central longitudinal axis;

a handle coupled with said proximal portion between said offset portion and a proximal end of said proximal portion, said handle having a grip with a transverse midpoint that is substantially aligned with said distal portion's central longitudinal axis;

a forearm support coupled with said proximal portion between said handle and said proximal end, said forearm support being oriented in substantially linear alignment with said handle along an axis substantially parallel to said proximal portion's central longitudinal axis; and

a pivoting connector coupled with a distal end of said distal portion, said pivoting connector having a range of rotational motion up to 90-degrees in each direction with respect to said distal end of said elongated member;

wherein said proximal portion comprises an adjustment mechanism, said adjustment mechanism being configured to adjust the length of said proximal portion between said handle and said forearm support.

14. The tool of claim 13 , further comprising a bristle assembly coupled with said pivoting connector.

15. The tool of claim 13 , wherein said distal portion comprises an adjustment mechanism configured to adjust the length of said elongated member.

16. The tool of claim 15 , wherein said adjustment mechanism comprises a spring-loaded locking button device.

17. The tool of claim 13 , wherein said adjustment mechanism comprises a spring-loaded locking button device.
