Abstract

A carrier assembly for a harness for carrying a motor-driven power tool, the carrier assembly including a back plate and an interface plate including connections for shoulder straps. The back plate includes a coupling interface on a front face arranged to be removably connected to a corresponding coupling interface on a rear face of the interface plate. The coupling interface of the back plate is adapted to be connected to and disconnected from the coupling interface of the interface plate in an at least partially translational or linear movement which is substantially parallel to the back plate.

First claim

The invention claimed is:

1. An adjustable carrier assembly for a harness for carrying a motor-driven power tool, the adjustable carrier assembly comprising a back plate and an interface plate including connections for shoulder straps, wherein the back plate comprises a coupling interface on a front face thereof arranged to be removably connected to a corresponding coupling interface on a rear face of the interface plate, wherein the coupling interface of the back plate is adapted to be connected to and disconnected from the coupling interface of the interface plate in an at least partially translational or linear movement which is substantially parallel to the back plate;
wherein the back plate further comprises a plurality of locking projections arranged in two parallel rows extending in a direction parallel to the longitudinal extension of the back plate, wherein the interface plate comprises a pair of resilient locking tabs arranged to come into locking engagement with a corresponding pair of locking projections to lock the position of the interface plate with respect to the back plate.

2. The adjustable carrier assembly according to claim 1 , wherein the coupling interface of the back plate comprises two parallel raised ridges extending in a substantially longitudinal direction of the back plate, each having at least one overhanging flange and presenting an L-shaped cross section with the flanges facing towards or away from each other, and the coupling interface of the interface plate comprises corresponding raised ridges, each having at least one overhanging flange and presenting an L-shaped cross section with the flanges of the interface plate facing in the opposite direction of the flanges of the back plate, wherein the raised ridges are arranged such that when the back plate and the interface plate are aligned with each other and brought together in a translational or linear movement parallel to the raised ridges, the flanges are slid into locking engagement with each other to retain the interface plate on the back plate.

3. The adjustable carrier assembly according to claim 1 , wherein the resilient locking tabs are formed as ribs extending in a direction parallel to the raised ridges on the interface plate into an opening therein and each comprises a main portion having a lateral projection adapted to engage the locking projections of the back plate, and a web portion connecting a distal end of the main portion to a central rib arranged between and at a distance from the locking tabs.

4. The adjustable carrier assembly according to claim 3 , wherein the central rib comprises a flange and has a T-shaped cross section, wherein the back plate comprises a central through-going slot arranged to receive the central rib when the back plate and the interface plate are aligned with each other and brought together in a translational or linear movement parallel to the raised ridges such that the flange is slid into locking engagement with a surface on a rear face of the back plate.

5. The adjustable carrier assembly according to claim 1 , wherein a proximal side of the locking projections in an insertion direction of the interface plate has a bevelled or chamfered surface.

6. The adjustable carrier assembly according to claim 1 , wherein a distal side of the resilient locking tabs in an insertion direction of the interface plate has a bevelled or chamfered surface.

7. The adjustable carrier assembly according to claim 4 , wherein leading and/or trailing edges of the flanges in an insertion direction of the interface plate has a bevelled or chamfered surface.

8. A harness comprising an adjustable carrier assembly according to claim 1 .
