Abstract

A handheld apparatus includes a handle at least partially engaging around a housing. The housing extends along a longitudinal axis from the back to the front end. The apparatus possesses a longitudinal plane which in a storage position runs perpendicular to the horizontal plane and contains the longitudinal axis. An operator-control region has a handle opening penetrating fully through the housing in the direction transverse to the longitudinal plane. The handle opening has in the direction of the longitudinal axis a distance point with the largest distance to the back end. The operator-control region extends in the direction of the longitudinal axis from the back end up to the distance point. The housing possesses an imaginary tangential plane which is only tangent to the housing, runs perpendicular to the longitudinal plane and is tangent to the handle. The imaginary plane is tangent to the housing in the operator-control region.

First claim

The invention claimed is:

1. A handheld, battery-operated work apparatus comprising:
a housing;
a work tool arranged on said housing;
a bale handle which at least partially engages at least one of around and over said housing;
said housing having a back end to which an operator-control region of said housing is assigned;
said housing having a front end on which said work tool is arranged;
said housing extending along a longitudinal axis from said back end to said front end;
an operator-controlled element for operation of an electric motor of the work apparatus arranged in said operator-control region;
wherein the work apparatus is configured so that it can be stored in a storage position on a horizontal plane;
wherein the work apparatus defines a longitudinal plane which in said storage position runs perpendicular to said horizontal plane and contains said longitudinal axis;
said operator-control region defining a handle opening which penetrates fully through said housing in a direction transverse to the longitudinal plane;
said handle opening having, in a direction of the longitudinal axis, a distance point with a largest distance measured in the direction of the longitudinal axis to said back end of said housing;
said operator-control region extending in the direction of the longitudinal axis from said back end of said housing up to said distance point;
said housing having a frontal region extending in the direction of the longitudinal axis from said distance point up to said front end;
said housing defining an imaginary tangential plane which is only tangent to said housing;
said imaginary tangential plane running perpendicular to said longitudinal plane;
said imaginary tangential plane being tangent to said bale handle; and,
said imaginary tangential plane being tangent to said housing in said operator-control region of said housing.

2. The work apparatus of claim 1 , wherein said imaginary tangential plane is tangent to said housing in said operator-control region of said housing at a touch point.

3. The work apparatus of claim 2 further comprising:
a further operator-controlled element disposed in said operator-control region;
said further operator-controlled element being configured to unlock said operator-controlled element or to hold a locking element in an unlocking position; and,
said touch point lying between said further operator-controlled element and said frontal region in relation to the direction of said longitudinal axis.

4. The work apparatus of claim 1 , wherein said tangential plane has a first side and a second side; said first side faces said horizontal plane in said storage position; and, said frontal region of said housing is arranged exclusively on said first side of said imaginary tangential plane.

5. The work apparatus of claim 1 , wherein said frontal region has a frontal region distance to said imaginary tangential plane; and, said frontal region distance is small and said work apparatus is configured such that said frontal region of said housing can contact said horizontal plane in an event of an impact of the work apparatus with said imaginary tangential plane on said horizontal plane.

6. The work apparatus of claim 5 , wherein said frontal region distance is smaller than 100 of a distance of said touch point to said horizontal plane.

7. The work apparatus of claim 1 , wherein said frontal region of said housing has an impact projection; said impact projection protrudes in a direction of said tangential plane; and, said frontal region has in a region of said impact projection a smallest distance to said tangential plane.

8. The work apparatus of claim 1 , wherein a battery shaft is arranged in said frontal region of said housing so that said housing can enclose a battery.

9. The work apparatus of claim 8 , wherein said frontal region of said housing has an impact projection; and, said impact projection is part of said battery shaft.

10. The work apparatus of claim 9 , wherein said impact projection forms an outer wall of said battery shaft.

11. The work apparatus of claim 8 , wherein said battery shaft is configured to receive the battery in an insert direction running parallel to said longitudinal plane.

12. The work apparatus of claim 8 , wherein said battery shaft defines an insertion opening; and, said insertion opening in said storage position is arranged on the side of the work apparatus facing away from said horizontal plane.

13. The work apparatus of claim 1 , wherein said operator-control region has a hand guard for bearing a hand when actuating said operator-controlled element; and, said imaginary tangential plane is tangent to said operator-control region on said hand guard.

14. The work apparatus of claim 13 , wherein said hand guard is formed as a projection of said operator-control region.

15. The work apparatus of claim 14 , wherein said hand guard is hump-shaped.

16. The work apparatus of claim 1 , wherein the work apparatus is a motor chainsaw, hedge shears or an angle grinder.

17. A handheld, battery-operated work apparatus comprising:
a housing having a front end;
a work tool arranged on said front end of said housing;
said housing having a back end to which an operator-control region of said housing is assigned;
said housing extending along a longitudinal axis from said back end to said front end;
an operator-controlled element for operation of an electric motor of the work apparatus being arranged in said operator-control region;
the work apparatus being configured so that it can be stored in a storage position on a horizontal plane;
the work apparatus defining a longitudinal plane which in said storage position runs perpendicular to said horizontal plane and contains said longitudinal axis;
said housing having a battery shaft;
a further operator-controlled element disposed in said operator-control region of said housing;
said further operator-controlled element protruding out of an operator-controlled element opening in said operator-control region in said storage position in a direction away from said horizontal plane;
a hand guard for bearing the hand when actuating said operator-controlled element formed by said housing in said operator-control region;
said operator-controlled element opening, in said storage position in a side view perpendicular to said longitudinal plane, having a low point corresponding to a point of the operator-controlled element opening having a smallest distance (d 2 ) to said horizontal plane;
the work apparatus defining an imaginary touch plane running perpendicular to said longitudinal plane through said low point and tangent to the battery shaft; and,
said hand guard protruding beyond said imaginary touch plane.

18. The work apparatus of claim 17 , wherein said operator-controlled element opening in said storage position is arranged on a side of said operator-control region facing away from said horizontal plane.

19. The work apparatus of claim 17 , wherein said battery shaft has an outer wall which is tangent to said imaginary touch plane.

20. The work apparatus of claim 17 , wherein said hand guard is formed as a projection of said operator-control region of said housing.
