This application claims the benefit of priority under 35 U.S.C. ยง 119 of German Application DE 10 2004 061 661.2 filed Dec. 22, 2004, the entire contents of which are incorporated herein by reference.
The present invention pertains to a carrying device for a respirator product.
A carrying device for carrying loads on the back has become known from DE 299 19 705 U1. A rocker is fixed to a carrying plate on the back of a carrier in a height-adjustable and rotatably movable manner. The rocker has two belt fasteners on its top side for a one-piece carrying belt extending from the rocker back to the rocker via two eyelets on the underside of the carrying plate. The one-piece carrying belt has a favorable effect on the use of the carrying device, because the extension of one shoulder belt exactly corresponds to the shortening of the other shoulder belt and the carrying device is always in a uniformly firm contact with the carrier's back. Differences in the length of the back and torsional movements of the upper body are compensated with the rocker arranged in a height-adjustable and rotatably movable manner.
The basic object of the present invention is to provide a carrying system with improved mobility for the carrier.
According to the invention, a carrying device is provided for a respirator product with a back plate and a rocker fastened to the back plate in a height-adjustable manner. A belt fastener and a second belt fastener are provided with a carrying belt extending from a first belt fastener via eyelets on the underside of the back plate to the second belt fastener. U-shaped shoulder supports made of a solid material are provided through which is led the carrying belt.
The shoulder supports are adapted to the shoulder and to the back of the carrier in a U-shaped pattern according to the present invention at the carrying belts. The shoulder supports consist of a solid material, preferably a hard plastic, so that they are lightweight, on the one hand, and can be deformed to a very limited extent only.
Compared to a shoulder support made of a flexible material, the subjective impression that the weight of the respirator product burdens the carrier's back is no longer created with the shoulder supports formed of a solid material. In addition, a greater distance can be better set between the carrier's back and the back plate of the carrying device with undeformable shoulder supports, which markedly increases the carrier's freedom of movement.
A carrying belt length adjustment means is advantageously provided for on the right-hand side of the belt only, because it can be operated in a simple manner there and a shortening of the length of the carrying belt on one side also affects the other side correspondingly.
The carrying properties are further improved when the shoulder supports are attached directly to the rocker. The carrying belts may be led now either through the shoulder support to the belt fasteners at the rocker or they are attached to the shoulder supports.
To further improve the carrying properties, a limiting stop, by which the shortening of the length of a shoulder belt is limited, especially when the carrying device is put on, is arranged at the carrying belt between the eyelets on the back plate through which the carrying belt is passed. The limiting stop may also be combined with the length adjusting means of the carrying belt.
The shoulder supports may advantageously contain fastening means for components of the respirator product. These components may be a pressure reducer or a pressure gauge for the cylinder pressure.
An exemplary embodiment of the present invention is shown in the drawings and will be explained in greater detail below. The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference is made to the accompanying drawings and descriptive matter in which preferred embodiments of the invention are illustrated.

Referring to the drawings in particular,
While a specific embodiment of the invention has been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
