209834/0611

After describing the essential parts of a preferred practical embodiment of the invention the mode of operation of this embodiment will now be described in the following.

If there is no knife blade in the Meseerscheidenkanal> is arranged, the support part 12 is held in its uppermost position by the compression spring "as in Pig * I is shown and in this position the counter pressure beam 19 rests against the upper housing wall 8 and it is preferred that relatively little or no play between the adjacent surfaces of the sharpening device 11 and this Bar 19 is given. Thus, only the tip of a knife blade 4 can be pushed into the recess J52 of the sharpening device 11 before this device with the »support part 12 is moved downwards against the action of the compression spring 10 and on this catfish is between of the blade edge 5 and the sharpening device 11 “Maintained in pressure” essentially over the entire movement of the blade in the knife blade

As the depth or height of the blade 4 generally increases in the direction of the handle 72 of the knife, the carrier portion 12 is progressively moved closer to the bottom when the Blade 4 inserted lengthways into the knife sheath will"

In addition, the engagement between the leading edge 48 of the counter pressure bar 19 and the upper edge 5 (a) of the blade _P causes the counter pressure bar 19 to be held in engagement with the upper housing wall 8, as shown in FIGS. 3 * 9 and 10 * Due the Sohwenkbefestlgung the Gegenruokelementes 1? the area of its engagement with the upper wall 8 shifts progressively when

209834/0811

the depth of the nit the counter pressure beam 19 in engagement Blade 4 is enlarged or reduced and. in this Look at the different positions of the bar 19 in the Pig. 8 and 9 pointed out. The counter pressure element 1? ensures that essentially the full Height of the blade 4 between the lateral guide surfaces is arranged, which are defined between the arms 22 and the flanges 21, at least over the larger part of the length of the blade 4, creating the possibility is largely reduced that the blade 4 is twisted laterally, and between the »support part 12 and the upper Housing wall 8 is stuck.

The counter-pressure element 15 has the further advantage « that the longitudinal force that is required is reduced * to cause an initial penetration of the knife blade 4 into the housing channel J5. This follows from "that Blade 4 initially against the counter pressure beam 19 in one Position is applied "which has a certain distance from the S ohwenkvorSprüngen 27" and it results in a mechanical one Advantage »This means that the upward pressure of the beam 19 against the wall 8 creates a downward pressure directed counterpressure / which is transmitted via the arms 22 and the flanges 21 to the projections 27 «to act on the Support part 12 to act opposite to the influence of the spring IO «and this counter pressure force is due to the Longitudinal distance between the beam 19 and the axis of the Projections 27 enlarged.

If this is desired, "the compression spring 10 can be arranged" in such a way that the upward force exerted by the spring 10 on the carrier part 12 remains essentially constant in all pivoting positions of the carrier part 12. For example, the spring 10 can be slidably engaged, generally on a lower surface of the carrier 12, so that the

209834/0811 ^ßAD

grip zone with the support part 12 generally in the longitudinal direction of the housing with an equilateral pivoting movement of the carrier part 12 is moved «This effect could be achieved by a suitable shaping of the spring 10 and the contour the lower surface of the support part 12 can be reached «which is in engagement with the spring 10»

When the knife blade 4 first recess in the sharpening the sharpening device 11 is inserted, the device 11 is tilted backwards about its pivot axis Moved position «as shown in FIGS 1st · When the blade 4 starts to be pulled out, the sharpening device 11 turns into a moved forward inclined position 'as shown in Fig. 10 is shown. If this is desired, the sharpening device can 11 be arranged in such a way that they have two different cutting angles on the knife blade 4 during the Pushing in and pulling out, this arrangement ensures a fine cutting edge 5.

The guide walls 18 of the support part 12 hold the knife blade 4 in alignment with the sharpening device 11 and the side flanges 21 and the arms 22 of the counter-pressure element 1? hold the blade 4 against excessive lateral Incline in the critical zone near the sharpener 11 «If there is excessive pressure on the knife is generally applied in the longitudinal direction, the buffer spring 34 acts as a compensator and reduces the possibility largely «that the blade 4 jams in the sharpening recess 32 is «The compression spring 10 serves the same purpose in the event« that an excessive downward Force is exerted on the knife "

A removal of the knife sheath housing 2 from the fastening is achieved by the fact that an inwardly

Is there any pressure on the push-button element 6? the catch plate 62 as indicated by arrow A in Pig. Il is shown, whereby the locking bar 65 of the interacting with it Shoulder 63 of the catch plate 62 is released. The housing 2 can then be lifted off at the front end, as shown by arrow B in Fig. 12 and after be pulled in front «around the Ansohl & goberflachen 57 and 58 to separate, after which the housing can be completely removed from the fastening «

The carrier part can be pulled out of the housing 2 in that the compression spring 10 is pulled downward, as shown by the arrow C in FIG. 13, namely in that finger pressure is exerted through the opening 43 in the lower housing wall Although it was mentioned above that such handling of the spring 10 is not required in a somewhat modified (not shown) embodiment, the support part-Sehwenkrippe can then fall out of the bearing recesses 15, so that the support part 12 as a whole through the open front end of the housing 2 can be moved out in the direction indicated by the arrow D in FIG. 14 "The insertion of the support part 12 is in the same way a simple process, since it is only necessary." The support part 12 in the longitudinal direction between the compression spring 10 and the upper wall To push 8 of the housing 2 , rock the pivot rib 14 engages in the bearing recesses 15.

It will be understood that the one described above is preferred The design may be changed materially without departing from the spirit and scope of the invention For example, the printing devices can anneal any of several forms, such as "B * a." or several helical springs * ^ one Luftsaote, one counterweight, magnetic or hydraulic devices »WeI-
