Definitions

  • the invention relates to a hand cutting knife with a circular knife disc according to the preamble of the main claim for the rolling removal of certain cut shapes or for cutting continuous webs, such as wallpaper or the like.
  • the knife protection cover is designed to be pivotable, as a result of which, after pivoting in the safety position, this protective cover covers the part of the knife disc which is not covered by the trough-shaped, knife-side end of the knife holder.
  • the knife disc is thus between the protective cover and the trough-shaped end of the knife holder, remains freely accessible on one side and can therefore lead to injuries, quite apart from the fact that you can injure yourself when you swivel the protective cover on the knife disc itself.
  • the invention is therefore based on the object to improve a hand cutting knife of the type mentioned in such a way that with simple and risk-free interchangeability of the knife disc, it is arranged so that it is covered absolutely securely in the knife holster and should be free from danger for the cutting process.
  • the knife disc is to a certain extent embedded in a two-part trough, one part being formed by the trough-shaped end of the knife holder and, on the other hand, by the likewise trough-shaped and pivotable protective cover, which is provided with an adjustment handle, with which the pivoting of the protective cover is free of danger can be done.
  • the knife disc, the protective cover and the shaft are assigned to the knife holder in such a way that they can be detached and plugged in, which means that these parts can be detached from one another transversely to the knife disc and can be put together again in the opposite direction, which also precludes any risk during these operations.
  • the pivotable, trough-shaped protective cover is arranged on the same side with respect to the knife disc as the trough-shaped end of the knife holder, but this is not mandatory, since the trough-shaped knife protective cover could also be arranged on the other side of the knife disc, which means that the knife disc is located between the two trough-shaped parts.
  • the above-mentioned arrangement of the two trough-shaped parts on one side of the knife disk is therefore preferred because advantageous developments to be described are thereby easier to implement, which will be explained in more detail below.
  • the pivotable protective cover is namely advantageously mounted on a hub arranged concentrically to the shaft in the trough-shaped end of the knife holder, and the hub and the pivotable protective cover are provided with end stops through which the pivotable protective cover can be snapped exactly in the open and closed positions.
  • the shaft is designed in the form of a plug pin with a larger diameter head and the head-free end of the plug pin is fixed with an attachable locking disk with respect to the trough-shaped end of the protective cover of the holder.
  • the pivotable protective cover 1 is also trough-shaped and has a circumferential web 2 which is guided along a circumferential web 3 of the trough-shaped end 4 of the knife holder 5.
  • This trough-shaped design and assignment of the end 4 of the knife holder 5 and of the protective cover 1 is particularly clear from FIG. 2.
  • the protective cover 1, the knife disc 6 and the shaft 7 are detachably and pluggably assigned to the knife holder 5, specifically, as can also be seen in FIG. 2, by means of the shaft 7 designed as a plug pin 11. These elements all together form the knife head 5 '.
  • FIGS. 1 As can be seen from FIGS.
  • the protective cover 1 is provided with an adjusting handle 8 which is sufficiently far with respect to the overall arrangement and above the cutter disk 6, as can be seen in particular from FIG. 2. Since the cutting edge of the cutter disk 6 is completely shielded from the circumferential webs 2, 3, the actuation of the adjusting handle 8 can be carried out without any risk.
  • the representation in Fig. 1 corresponds to the position of the protective cover 1 ready for cutting, i.e. that is, with its circumferential web 2 parallel to the circumferential web 3 of the trough-shaped end 4 of the knife holder 5.
  • the cut-side boundary edges of the two trough-shaped parts of the knife holder 5 are arranged as shown in dashed lines in order to ensure an unobstructed cut of the knife.
  • the pivotable protective cover 1 is mounted on a hub 9 arranged in the trough-shaped end 4 of the knife holder 5 concentrically with the shaft 7, and the hub 9 and the pivotable protective cover 1 are provided with end stops 10 '.
  • a circularly curved elongated hole 10 "in the protective cover 1 leads to sufficient elasticity of the web 10" which remains between the elongated hole 10 "and the hub attachment opening 9 ', on which the end stops 10' are seated, which, depending on the position and when the protective cover 1 is assigned to the trough of the knife holder 5 cooperate with a corresponding cam-shaped stop 10 on the hub 9.
  • These stops 10, 10 ' are arranged in such a way that the locking of the cam-like stop 10 once the closed position (FIG. 7) and once the open position (FIG. 1) corresponds.
  • the shaft 7 is in the form of a plug pin 11 with a larger diameter head 12, the head-free end 13 of the plug pin 11 being fixed with an attachable locking disk 14 with respect to the trough-shaped end 4 of the knife holder 5, as shown in FIG. 2 becomes clear. From this it can also be seen that only the locking disk 14, which of course has a corresponding sliding gap, only has to be pressed off by the plug pin 11 in order to be able to take the whole structure apart. The release of the locking disk 14 takes place completely safely from the knife disk 6 on the other side of the knife holder 5, so that after loosening the locking disk 14 only the plug pin 11 and the knife disk 6 are to be removed from the trough, replaced and replaced.
  • the shaft 7 and the plug pin 11 are rotatably arranged in the knife holder 5, for which the hub 9, as shown in FIG. 3, is provided with a straight surface 18 within the plug-through hole and the plug 11 itself is also provided with a corresponding surface 17. Since the shaft 7 or the plug pin 11 is thus fixed, the cutter disk 6 rotates on the shaft 7, which elements are therefore provided with a bush 15 rotatably fitted on the shaft 7, the bush 15 being provided with a flange collar 15 'and this is arranged adjacent to the head 12 of the plug pin 11, as is also clear from FIG. 2.
  • the knife holder 5 or the knife head 5 ' on which, as can be seen from FIGS. 1, 2 and 7, a small glass cutting knife 19, as shown, can also be arranged with a connection adapter 16, with which the entire cutter head 5 'can be interchangeably assigned to a suitable cutter handle 20.
