An SCBA frame for mounting self-contained breathing apparatus bottle vertically such that the frame can articulate with the back of a user, comprising an upper plate, intermediate plate and a lower plate each connected by attachment mechanisms. Each of the plates may comprise a top edge, a bottom edge, and a pair of sides. A first coupling mechanism coupled to the bottom edge of the upper plate and a top edge of the intermediate plate and a second coupling mechanism coupled to the bottom edge of the intermediate plate and the top edge of the lower plate. The first and second coupling mechanisms allow the upper plate, intermediate plate, and lower plate to move about the horizontal axis and torsionally in line with the user's movement. The first and second coupling mechanism comprises a pair of attachment mechanisms located proximate the sides of the upper plate and intermediate plate.

Disclosed is a vacuum cleaner assembly (10) including a harness assembly having a support bracket (11) and a vacuum cleaner (12) supported by the brackets (11). The brackets (11) are intended to be worn by a user so that the vacuum cleaner (12) is positioned adjacent the back of the user.

A harness for a back-pack comprises a chest harness A, a strut mechanism in the form of a flexible spine B and a hip belt C. The flexible spine B provides a sprung, damped connection between the chest harness A and the hip belt C, so that the load of the backpack is transferred through the flexible spine B to the hip belt C, while the flexible spine can extend to accommodate movement of the wearer's body. The chest harness A comprises straps 12, 15 which are interconnected at the front of the wearer by a buckle 14. Abdominal straps 15 are connected to the buckle 14 by flexible wands 16 which flex under the breathing action of the wearer to retain the load securely against the wearer's back without restricting breathing.

A wearable battery pack is provided. The wearable battery pack includes a battery pack body, a battery cell and a housing accommodating a battery cell and a wearable device capable of wearing so that the battery pack body at least be worn on a user's back. The battery pack body has a heat dissipation channel running through one side of the battery pack body to the opposite side; the side of the battery pack body which is penetrated by the heat dissipation channel is located between the back of the user and the other side when the user carries the battery pack body. The invention provides a wearable battery pack that can be carried by users. The wearable battery pack has achieved good heat dissipation performance and can be carried by users comfortably.
