Description

The invention relates to a user-portable machining system. The EP 3 023 201 A Disclosing a chainsaw arrangement comprising a chainsaw and a battery connected to a drive motor of the chainsaw via a power cable, wherein the chainsaw has an elastic safety element which is fixed to a housing of the chainsaw by a fastening means, and wherein a connection device is provided for connecting the safety element to the operator. One object of the invention is to create a user-portable machining system which has improved properties. This problem is solved by the subject matter of the independent patent claim. Preferred embodiments are the subject matter of the dependent patent claims. A user-portable machining system according to the invention comprises a battery pack, in particular a replaceable one, for storing electrical energy. The machining system is portable by a user, particularly for work at height; that is, the user can carry the machining system while working at height. The machining system includes an electric chainsaw, which is separate from the battery pack and can be operated by means of electrical energy from the battery pack. The chainsaw, in particular, forms a hand-held and/or hand-guided machining device of the machining system. Furthermore, the machining system comprises an electrical wiring device, which serves to electrically connect the chainsaw and the battery pack. The machining system also has a locking element, which serves to transmit power between the chainsaw and the battery pack. The functions of the electrical connection and the power transmission connection can therefore each be fulfilled by different and/or separate components of the machining system. The machining system also has a casing for enclosing at least one section of the wiring device and at least one section of the locking element. The casing includes an intermediate wall for separating the enclosed section of the conductor assembly from the enclosed section of the fuse element. The intermediate wall can, in particular, run directly between the enclosed section of the conductor assembly and the enclosed section of the fuse element. In this way, particularly through separation by means of the partition, the adhesion and/or rubbing of the wiring and the safety element against each other can be reduced or even completely avoided. This can be particularly advantageous if the chainsaw of the user-friendly power tool is dropped by the user, especially accidentally or intentionally during a drop test. In this case, it is desirable that the chainsaw and the battery pack move away from the user together without interrupting the electrical connection or the power transmission connection. By reducing or even avoiding the adhesion and/or rubbing of the safety element and the wiring, an interruption of the electrical connection at the battery pack side can be advantageously prevented. The electric battery pack can be an electric battery pack, especially one with multiple electric battery cells. The safety element can be referred to synonymously as a "strop". Alternatively or additionally, the safety element can form and/or feature a safety strap. The safety element can be designed to be textile and/or cut-resistant and/or electrically insulating. Advantageously, the securing element may be made of or consist of polyester. It is understood that other fibers, in particular synthetic fibers, and/or combinations of different fibers may also be suitable for the securing element. The securing element may, at least in some areas, comprise a woven and/or braided and/or knitted fabric, in particular with or made of fibrous material. The securing element may, in particular, be designed similarly to a lashing strap. The casing is not designed to transmit power between the chainsaw and the battery pack. The casing may be loosely movable along the covered section of the cable assembly and/or along the covered section of the safety element. In one embodiment of the invention, the sheathed section of the conductor assembly and the sheathed section of the locking element run essentially parallel to each other. Alternatively or additionally, the sheathed section of the conductor assembly and the sheathed section of the locking element are essentially parallel to each other, in particular by means of the sheath. In particular The wiring is not wound around the safety element. In a further embodiment of the invention, the locking element is elastically designed. Alternatively or additionally, the locking element has a total locking element length, particularly a maximum length, that is less than the total length of the cable assembly. Under longitudinal tensile stress on the locking element and the cable assembly, the locking element can thus advantageously reach its total locking element length before the cable assembly is fully stretched to its total length. In a further embodiment of the invention, the casing has a first chamber, in particular a channel
