Description

The The invention relates to a utility knife for the craft sector with adjustable and exchangeable blade and writing function. Universal knife of this type exist for the craft sector from a knife shaft, with a guide and a Locking device for the adjustable and replaceable Blade and with a guide and a fixation for a write element is provided.

A universal knife of this kind is among others by the DE 196 23 167 A1 known. At a small distance above the guide for the knife blade in the knife shaft a guide for a conventional ballpoint pen refill, a writing element is provided, which is fixed by means of a press fit in the blade shank. The writing head of the ballpoint pen refill protrudes at the tip of the knife blade opposite side, the knife shaft.

A Such design and arrangement of the writing elements on the knife is disadvantageous in many respects. When handling the knife is It is necessary regularly with the palm of your hand pressure to exercise on the knife shaft. The tip of the pen refill is a major obstacle.

In the usual Field of application of the universal knives are often materials rough, dirty and porous surface. or processed. The ballpoint pen refill fulfills its writing function there not or only to a limited extent. This Utility knife is therefore only in the office or with restrictions can be used in the household.

However, writing tools are also known in this area of application ( DE 24 14 317 A1 ), in which a plurality of writing elements or a knife element from a cavity in the shaft can be selectively brought into a common guide and in working position and locked. The stability of such a writing instrument is sufficient for writing functions, but not for demanding cutting functions.

The The object of the invention is to provide a utility knife with cutting and to propose writing for the craft sector, that's easy in all functions with high stability, reliable and easy to handle.

According to the invention the problem solved by the features of claim 1.

The Arrangement of the guide for a commercial Pin whose active writing element can be positioned above the knife tip is, and a locking device on the measuring shaft for the pen, the pen of different length in different Positions can also fix the use of Pens with hefty graphite leads, which are on almost every ordinary Material to leave visible marks. The top of the mine hinders not the handling of the knife.

The Invention will hereinafter be an embodiment be explained. In the accompanying drawings demonstrate.

The knife shaft 1 The universal knife for the craft sector has a guide 11 for the knife blade 2 and a guide 14 for a pen 3 , The leadership 11 for the knife blade 2 is a locking device 12 assigned to the usual type. The knife blade 2 can be moved back to the working position after fixing a blunt knife section and fixed there.

The leadership 14 for the pen 3 is parallel to the leadership 11 the knife blade 2 and arranged above it. Their cross section is the shape of the usual pens 3 customized. The central portion of the guide is preferably open on one side so that you can move the shaft of the pin by hand axially. In the front section of the guide 14 is in the wall of leadership 14 a threaded hole 141 for the clamping screw 1511 the locking device 151 intended. The locking device 151 is a special form of fixation device 15 that allows the tip of the writing element 31 of the pens 3 at different length of the pin 3 in different positions relative to the active tip of the knife blade 2 to position.

Instead of a clamping screw 1511 you can also locking devices - similar to the usual locking devices 12 for knife blades 2 use. The pencils 3 are usually writing elements 31 - like mines that are guided and fixed in a shaft. The shank can be a usual wooden shaft, which surrounds the mines - usually made of graphite - positively and adhesively. To these pencils 3 include commercial pencils and the so-called carpenter pencils. Are used mainly round pins or pins with regular polygonal Cross sections, it is useful in the rear section of the knife shaft 1 a common point device 16 provided.

It But it is also conceivable that pens in the form of pens or the like can be used. But that is only appropriate if the materials to be machined with the utility knife the Dye of the mines or writing elements also reliable accept.

To reduce the cross section of the blade shank 1 can be in the context of the invention, the back of the knife blade 2 Involve in the leadership of the pen. It is also conceivable, the back of the knife blade 2 as a writing element ( 31 ) train. The knife blade 2 then becomes the shaft of the pen at the same time 3 ,
