Description

The invention relates to a compact multifunctional tool for use when staying in nature such as when practicing hunting, fishing, hiking or nature camping, which consists of a tool holder with a handle that is intended as a magazine and carrier for selected specific tools.

State of the art

Combinable universal tools are known in order to avoid having to carry several individual tools, such as an axe, a spade, a knife and/or others, when practicing hunting, fishing, hunting, hiking or nature camping in order to carry out the tasks that arise in nature. They are lighter than the sum of the individual tools. Various types of work can be carried out with them. The most common universal tools are called folding knives. In addition to a blade, you have other tools at your disposal. They can be folded out individually and are blocked in their working position. The equipment of such knives depends on the specific areas of application of the user.

When subjected to heavy loads, however, the individual tools often cannot withstand higher loads or limit their manual handling. For example, a multi-tool camping tool is known that is equipped with a fold-out hammer or an ax. However, the dimensions of these individual tools are so small that the hand gripping the handle is injured during use and the impact force of the user cannot be optimally transferred to the tool.

To achieve a higher impact effect with a hammer and an ax is from the reference DE 20 2009 001 0376 U1 known a multifunction tool that can be attached to a handle. It consists of a sufficiently stable and easy-to-handle handle as a handle, which is suitable for twist-proof accommodation of various tool attachments with a screw cap.

One such tool attachment is a head piece that is hammer-like in shape and can alternately receive a compact wear-resistant striking head for use as a hammer or a blade for use as an axe. Other tool attachments with adapted connections, such as a knife or a saw, can be attached to the handle as required. Another specifically designed multifunction tool is from the publication DE 20 2006 015 859 U1 known. It also consists of a hollow handle as a handle to which various specially designed tool attachments can be attached. The main tool is a spade blade designed according to the basic principle of a folding spade, which is provided with a digging edge, a cutting edge, a sawing edge and a reinforcing edge. The spade blade also accommodates other tools designed for specific jobs, such as a multi-purpose mandrel, a hammer, a fork, a crowbar and others. To use the multifunction tool, the spade blade and hollow handle are secured against twisting and screwed together.

object of the invention

It is the object of the invention to create a multifunctional tool which is suitable both for the use of various fold-out individual tools and a solid tool attachment and which has advantageous usage properties. It should be able to be adapted in specific versions to the needs of different areas of application.

This task is solved by a combination of a multifunctional tool consisting of individual tools that can be folded out and a multifunctional attachable tool that can be pulled out and pushed in. For small, flat tools that are subject to low stress, the arrangement is provided with a locking mechanism, as with the knife edge of a folding knife; the pull-out and push-in variant is selected for the arrangement of tools that are subject to higher stress.

The tool holder consists of a handle that is U-shaped in cross section and accommodates a tool insert consisting of blade-like tools that can be folded out individually. Furthermore, the handle takes on a push-in and pull-out multifunctional attachment tool.

The slip-on tool consists of a tubular handle with a spade blade arranged on the side. This spade blade can be slightly curved, has a front digging edge, is reinforced on the sides and has a cutting edge for use as an axe. A formation for use as a hammer head is provided between the cutting edge and the handle.

The tube of the handle of the slip-on tool can be almost completely accommodated by the handle when pushed in. For using the individual tools of the attachment tool, it is pulled out of the handle to a certain length and held and fixed by means of a spring catch. Thus, when using the attachment tool as a spade, hammer or axe, the user can use the entire handle length and at least half the length of the tubular handle.

The tool insert housed inside the handle is designed like a folding knife. It consists of individually fold-out individual tools that can be a knife, fish scaler, nail remover, linear, saw, minus screwdriver, can opener, bottle opener, file, Phillips screwdriver or another blade-shaped individual tool, depending on the intended area of application. A tool blade can be designed for one, two or more areas of application. These individual tools can be moved independently of one another and are fixed individually in the folded-in rest position and in the folded-out working position.

The tool holder is designed ergonomically and in a length adapted to the intended scope of use with the aim of optimal handling. So that the respective tool attachment can be attached to the tool holder and released again in a simple manner and can withstand the loads it is subjected to, the attachment option is designed to be compact and robust.
