Towable transport and rescue blank. - Dragbar transport-och räddningsackja.

The invention relates to a pullable transport and rescue blank comprising a base extending substantially beyond human length, acting as a sliding surface, in the central region of which there is a bending weakening, in which area the base can be bent into an arc so that the base in front of the bend forms an angle to the rear.

A conventional transport and rescue blank is rigid along its entire length and is equipped with 1-foot legs 11a at the rear. Supporting the front end of the barn requires considerable force, and the barn is not otherwise off-road. This well-known rescue tank is only suitable for short transfers from the scene of an accident to an ambulance. This known rescue element is not suitable for longer human transport by terrain. On the other hand, sledge-like slings are known, which rest on the ground with their entire sliding base and are pulled by a rope. Such conveyors are well suited for towing by snowmobile, but for heavy hauling it is heavy. One person cannot properly pull another person to be rescued in terrain conditions (closed, uphill).

Collapsible ovens with a transverse bending joint in the central region are also known. However, they do not provide any protection or attachment to the person or goods being transported, the bending joint cannot be stiffened if necessary, and no attention has been paid to the fact that the cradle can be easily pulled by manpower.

The object of the invention is to provide a new type of towable transport and rescue unit which is easy and light to pull by manpower in off-road conditions, which has versatile operating characteristics and is also suitable as a snowmobile towable transport unit. A further advantage of the invention is that the container can be folded to a small size for storage.

The object of the invention is achieved on the basis of the features of the invention set out in the appended claim 1. Other claims set forth preferred embodiments of the invention.

In the following, an embodiment of the invention will be described in more detail with reference to the accompanying drawing, in which Fig. 1 shows a shelf according to the invention seen from above, Fig. 2 shows a shack seen from the side and Fig. 3 shows a cross section of the shelf.

The plate-like base 1 of the kiln is made of one piece as a plastic lever cross. The bottom is in the shape of a low cross-section gutter and its front end 10 curves upwards. The edges of the sole have reinforcing ribs 8, which give the otherwise thin and light sole the necessary 1 stiffness.

In the central region of the base there is a bending weakening 3, in the area of which the base can be bent to a gentle arc. In the area of the bending point 3, the side edge reinforcements 8 are cut or weakened so that the cross section of the base at the bending point 3 can be straightened straight (the edges 8 bend outwards and downwards) when the base 1 is bent from the bending point 3.

The kiln is also provided with a cover 6, which may be a water-repellent plastic fabric. The cover 6, alone or together with the base, forms a bag or tube in which the person or goods to be transported can be placed. The cover 6 is attached to the base 1 near the edges 8 of the base. The bag-like cover 6 can be folded and attached with a velcro fastening 7 to the desired tightness around persons or goods of different sizes. The mouth opening of the cover is provided with a groove strip 13 to close the mouth of the cover bag.

Attached to the front end of the base 1 is a cover flap 12 which has a double function. It serves, on the one hand, as a cover flap for the mouth opening of the cover bag 6 and, on the other hand, as a fastening base for the carrier and traction straps 14. The carrying and pulling straps 14 can be placed over the shoulders of the person pulling the crotch, whereby the cover flap 12 rests against the back of the puller. In this case, the base 1 is bent from the bending point 3 so that the front part 4 of the base faces obliquely upwards and the front end 10 of the base rests against the lumbar spine. In this case, the person to be rescued is located in the crankcase in a semi-sitting position, the upper body on the front part 4 of the base and the lower body on the rear part 2 of the base, which acts as a sliding surface against the ground. Of course, it is possible to place sliding aids under the rear part 2 of the base, e.g. on molten ground for traction. With such accessories, the use of the kiln can be extended even to molten asphalt roads.

In order to use the ingot as a rigid, straight transport ingot along its entire length, e.g. when pulling the ingot on a snowmobile, tensioning straps 9 are attached to the edges 8 of the base 1, allowing the base 1 to be pulled more trough so that the base 1 stiffens in the bending point 3. Attached to the front end of the base is a pivotally hinged towing eye 5 and at the rear end of the base there is a towing loop 15, whereby several boilers can be connected in series for towing by a snowmobile.

The furnace according to the invention is also suitable for military use and camping purposes. Ahkio can also serve as a sleeping pad by placing a sleeping bag in the cover bag 6.

For the storage of the blank or, for example, for transport in public transport, the blank can be folded twice by a bending point 3, whereby the blank takes up a small space and is easily portable.

Claims (7)

A towable transport and rescue blank comprising a base (1) acting substantially as a human length as a sliding surface, in the central region of which there is a bending weakening (3), in the region of which the base can be bent so that the base (4) in front of the bending point (3) forms at an angle to the rear of the base, characterized in that a cover (2) is attached to the base (1), which alone or together with the base forms a bag or tube in which the person or goods to be transported can be placed, and carrying and pulling straps are attached to the front end ( 14), which can be placed over the shoulders of the person pulling the blank, and that the side edges (8) of the base (1) are provided with tensioning straps (9) by means of which the base (1) can be pulled into a trough so that the base also stiffens in said bending point (3).
