Abstract

A harness has a support base and a support strap unit for the support base, and a holding device for releasably holding a battery pack in a support position on the support base. The holding device has a docking mechanism on the support base for pivotably docking the battery pack in a docking position, and a securing mechanism for securing the battery pack in the support position pivoted in towards the support base with respect to the docking position. The docking mechanism is arranged on a lower region of the support base, and the securing mechanism has a securing slide which is arranged displaceably on the support base between a release position and a securing position and has a securing hook, or a securing lever which is arranged pivotably on the support base between a release position and a securing position and has a securing bow. The securing hook or securing bow is designed to engage securely behind a corresponding mating securing element of the battery pack in the support position.

First claim

What is claimed is:

1. A harness, comprising:
a support base;
a support strap unit for the support base; and
a holding device for releasably holding an object in a support position on the support base,
wherein
the holding device comprises a docking mechanism on the support base for pivotably docking the object in a docking position, and a securing mechanism on the support base for securing the object in the support position pivoted in towards the support base with respect to the docking position,
the docking mechanism is arranged on a lower region of the support base, and
the securing mechanism comprises:
a securing lever which is arranged pivotably on the support base between a release position and a securing position and has a mechanically rigidly connected securing bow, which is designed to engage securely behind a corresponding mating securing element of the object in the support position.

2. The harness according to claim 1 , wherein the docking mechanism comprises a pivot axis, substantially parallel to an underside of the support base, for the pivoting movement of the object into the support position.

3. The harness according to claim 1 , wherein the securing bow comprises a run-on face extending in an arc shape with a non-constant spacing from a pivot axis of the securing lever, the mating securing element being configured to be placed against the run-on face with a spacing from the pivot axis, which spacing decreases with increasing pivoting of the securing lever in the direction of the securing position.

4. The harness according to claim 1 , wherein the securing bow comprises a run-on face extending in an arc shape with a non-constant spacing from a pivot axis of the securing lever, the mating securing element being configured to be placed against the run-on face, wherein the run-on face extends from a start point as far as an end point corresponding to the securing position of the securing lever, and a spacing of a run-on contact point of the run-on face with the mating securing element from the pivot axis of the securing lever decreases with increasing pivoting of the securing lever in the direction of the securing position from the start point until reaching an inflexion point of the run-on face, and the run- on face is designed at the inflexion point to provide a reversal of a torque, which is exertable on the securing lever by the mating securing element, from a torque acting in the direction of the release position to a torque acting in the direction of the securing position.

5. The harness according to claim 1 , wherein the securing lever comprises an ejector contour which, during the pivoting of the securing lever in the direction of the release position, is designed to exert on the object an ejector force acting in the direction of the docking position.

6. The harness according to claim 5 , wherein the ejector contour comprises at least one of an ejection pressure face acting on a mating contact face of the battery pack, on a side of the securing bow directed away from the run-on face, and an ejection pressure face acting on the mating securing element of the object, on a side of an ejector cam of the securing lever directed towards the run-on face.

7. The harness according to claim 1 , wherein the securing lever comprises a user-actuated control element which is located on a side of the support base directed away from an object coupling side of the support base.

8. The harness according to claim 1 , wherein the holding device comprises a cushioning spring arrangement which provides the object, in the support position, with elastic cushioning having a resilience acting in the outward pivoting direction.

9. The harness according to claim 1 , wherein the support strap unit comprises a shoulder strap unit, a waist strap unit and a joint unit which connects the waist strap unit to the support base in an articulated manner, wherein the joint unit comprises a double joint by which the waist strap unit is connected to the support base so as to be pivotable about two pivot axes, wherein one of the two pivot axes runs substantially parallel to a plate plane of the support base, and the other pivot axis runs substantially perpendicularly with respect to the plate plane of the support base.

10. The harness according to claim 9 , wherein the joint unit is formed by an autonomous component which is fastened on the one hand to the waist strap unit and on the other hand to the support base.

11. The harness according to claim 9 , further characterized in that one pivot axis runs substantially between and parallel to two mutually facing side edges of the waist strap unit and of the support base, and the other pivot axis runs, offset with respect to this pivot axis, in the direction away from the waist strap unit.

12. The harness according to claim 1 , wherein the support strap unit comprises at least one shoulder strap unit, which is releasably connectable to the support base, and comprises at least one flexurally stiff strap holder which, by means of a latch mechanism, is configured to be releasably locked at several different heights on the support base, and at least one flexible strap web connected to the strap holder.

13. The harness according to claim 12 , wherein the latch mechanism provides several latches for the at least one strap holder at different heights on the support base, wherein the respective latch comprises a latch release position and, upwardly offset in relation to the latch release position, a latch holding position, between which positions the strap holder is vertically displaceable on the support base.

14. The harness according to claim 12 , wherein the latch mechanism comprises a releasable snap-in lock, which holds the at least one strap holder locked in the respective latch holding position.

15. The harness according to claim 1 , wherein the object is a battery pack configured to be worn on the back and to supply electrical energy to hand-held electrical tools.

16. A tool kit, comprising:
a harness; and
a battery pack configured to be worn on the back and to be secured to the harness, said battery pack supplying electrical energy to hand-held electrical tools, wherein the harness comprises:
a support base;
a support strap unit for the support base; and
a holding device for releasably holding an object in a support position on the support base,
wherein
the holding device comprises a docking mechanism on the support base for pivotably docking the object in a docking position, and a securing mechanism on the support base for securing the object in the support position pivoted in towards the support base with respect to the docking position,
the docking mechanism is arranged on a lower region of the support base, and
the securing mechanism comprises:
a securing lever which is arranged pivotably on the support base between a release position and a securing position and has a mechanically rigidly connected securing bow, which is designed to engage securely behind a corresponding mating securing element of the object in the support position.

17. The tool kit according to claim 16 , further comprising:
a hand-held electrical tool configured to be supplied with electrical energy from the battery pack.

18. The tool kit according to claim 17 , wherein the electrical tool is an electrically powered gardening tool or forestry tool.

19. A harness, comprising:
a support base;
a support strap unit for the support base; and
a holding device for releasably holding an object in a support position on the suppo
