Abstract

An ergonomic scoop assembly including a scoop subassembly and scoop support subassembly. The scoop assembly is preferably detachably connectable to the scoop support subassembly. The scoop support subassembly includes a saddle member for contacting the ventral side of a user'"'"'s forearm and structure for releasably securing the scoop support subassembly to the user'"'"'s forearm. The scoop support subassembly further includes a rear portion to which the saddle member is attached and a fore portion attached to a handle of the scoop subassembly. When the scoop support subassembly is attached to the user'"'"'s forearm the handle of the scoop subassembly defines an angle with respect to the longitudinal axis for the user'"'"'s forearm of between about 115° to about 125°. The scoop assembly enables the user to comfortably and effectively perform scooping operations for prolonged periods of time with minimal fatigue and at considerably reduced potential for cumulative trauma injury to the user'"'"'s upper extremities versus conventional scoop designs.

Claims

1. A manually operated scoop assembly comprising:

a scoop subassembly comprising a bowl portion and a handle portion rearwardly from said bowl portion, wherein said bowl portion is upwardly open and comprises a base defining a leading edge, side walls contiguous with said base and a substantially vertical rear wall connected to said base and side walls, wherein said handle portion projects downwardly and rearwardly from said rear wall to define a handle angle of between 30°

to about 60°

with respect to said rear wall;

a scoop support subassembly for connecting said scoop subassembly to a user'"'"'s forearm; and

means for attaching said handle portion to said scoop support subassembly such that said handle portion and longitudinal axis of a user'"'"'s forearm define an angle φ

between about 115°

to about 125°

when said scoop assembly is connected to a user'"'"'s forearm.

2. The assembly of claim 1 wherein said angle φ

is about 118°

.

3. The assembly of claim 1 wherein said attaching means comprise means for releasably attaching said handle portion to said scoop support subassembly.

4. The scoop assembly of claim 1 wherein said handle angle is about 45°

.

5. The scoop assembly of claim 1 wherein said scoop support subassembly comprises a rigid frame member, a saddle member connected to said rigid frame member and adapted to contact the ventral side of a user'"'"'s forearm, and means for releasably securing said scoop support subassembly to a user'"'"'s forearm.

6. The scoop assembly of claim 5 further comprising means for adjustably securing said saddle member with respect to said rigid frame member.

7. The scoop assembly of claim 5 wherein said means for releasably securing comprise at least one strap attached to said saddle member and adapted to releasably fasten said saddle member into abutting contact with the ventral side of a user'"'"'s forearm.

8. The scoop assembly of claim 5 wherein said rigid frame member comprises a rear portion having a first longitudinal axis extending substantially parallel to the longitudinal axis of a user'"'"'s forearm when said scoop support subassembly is secured to a user'"'"'s forearm, wherein said rigid frame member further comprises a fore portion having a second longitudinal axis extending at said angle φ

from said first longitudinal axis, and wherein said attaching means comprises means for attaching said handle portion to said fore portion.

9. The scoop assembly of claim 8 wherein said attaching means comprises means provided in said handle portion for releasably receiving said fore portion.

10. The scoop assembly of claim 9 wherein said means for releasably receiving comprise a socket dimensioned to substantially matingly receive said fore portion.

11. The scoop assembly of claim 10 wherein said fore portion and said socket are substantially square in cross-section.

12. An implement support apparatus for use with a manually operated implement whose operative motions comprise thrusting and lifting, said apparatus comprising:

a rigid frame member, which comprises a rear portion having a first longitudinal axis extending substantially parallel to the longitudinal axis of a user'"'"'s forearm when said support axis is secured to a user'"'"'s forearm, wherein said rigid frame member further comprises a fore portion having a second longitudinal axis extending at an angle φ

from said first longitudinal axis,

a saddle member connected to said rigid frame member and adapted to contact the ventral side of a user'"'"'s forearm;

means for releasably securing said implement support apparatus to a user'"'"'s forearm;

means for attaching a handle of an implement to said fore portion of said rigid frame member such that the implement handle and the longitudinal axis of a user'"'"'s forearm defines said angle φ

of between about 115°

to about 125°

when the implement handle is attached to said rigid frame member and said implement support apparatus is secured to a user'"'"'s forearm.

13. The implement support apparatus of claim 12 further comprising means for adjustably securing said saddle member with respect to said rigid frame member.

14. The implement support apparatus of claim 12 wherein said means for releasably securing comprise at least one strap attached to said saddle member and adapted to releasably fasten said saddle member into abutting contact with the ventral side of a user'"'"'s forearm.
