Abstract

A harness for a battery pack that can be worn on the back and that supplies electrical energy to hand-held electrical tools includes a support base and a support strap unit for the support base, as well as 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 on the support base 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.

First claim

What is claimed is:

1. A harness for an object configured to be worn on the back, the harness comprising:
a support base;
a support strap unit for the support base; and
a holding device for releasably holding the 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,
the securing mechanism comprises a securing slide which is arranged displaceably on the support base between a release position and a securing position and comprises a securing hook, which is designed to engage securely behind a corresponding mating securing element of the object in the support position, or
the securing mechanism comprises a securing lever which is arranged pivotably on the support base between a release position and a securing position and comprises a securing bow, which is designed to engage securely behind a corresponding mating securing element of the object in the support position,
the securing slide or 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.

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, when the object is not docked, the securing slide is located in the securing position, and the securing slide comprises a run-on bevel which is designed, by interaction with the mating securing element, to displace the securing slide automatically in the direction of the release position when the docked object is pivoted inwards in the direction of the support 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, against which run-on face the mating securing element can be placed with a spacing from the pivot axis, which spacing decreases with increasing pivoting of the securing lever in the direction of the securing position.

5. 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 with a resilience acting in the outward pivoting direction.

6. The harness according to claim 1 , wherein the object is a battery pack configured for supplying electrical energy to hand-held electrical tools.

7. A harness, comprising:
a support base; and
a support strap unit for the support base, 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,
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.

8. The harness according to claim 7 , 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.

9. A harness, comprising:
a support base; and
a support strap unit for the support base, 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,
the harness is configured for carrying an object to be worn on the back, said harness comprising a holding device for releasably holding the 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, and the docketing mechanism is arranged on a lower region 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. A harness, comprising:
a support base; and
a support strap unit for the support base, wherein the support strap unit comprises at least one shoulder strap unit, which is releasably connectable to the support base,
wherein
the shoulder strap unit comprises at least one structurally rigid strap holder which is configured, by means of a latch mechanism, to be releasably locked at several different heights on the support base, and at least one flexible strap web connected to the strap holder.

12. The harness according to claim 11 , 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.

13. The harness according to claim 11 , 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.

14. The harness according to claim 11 , wherein the harness is configured for carrying an object to be worn on the back, said harness comprising a holding device for releasably holding the 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, and the docketing mechanism is arranged on a lower region of the support base.

15. The harness according to claim 11 , wherein the support strap unit comprises 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 to 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 plan
