Definitions
- the invention relates to a pair of scissors Preamble of claim 1.
- each Opening angle of the Beck with an even joint play good cutting properties and an individually soft adjustable cutting feel achieved.
- a soft cutting feel is provided between the ring and the Oberbeck at least one sliding washer Plastic - preferably made of Teflon - to arrange (claim 2 to 3).
- a corresponding self-locking adjusting nut is provided that the External thread of the head transverse to the longitudinal axis with a Bore is provided, in which a preferably elastic Plastic pin is arranged, the ends of the pin take up part of the external thread.
- This can be a shorter external thread can be provided, with a flatter adjusting nut has a very low profile Scissors can be realized (claim 6).
- the adjusting nut can also be used with a tool adjustable via a tool holder be formed (claim 8).
- the invention is based on three exemplary embodiments described in more detail.
- FIG Shear 1 A first exemplary embodiment is shown in FIG Shear 1 shown, the lower and upper Beck 2, 3rd has, which is rotatable by means of an articulated connection 4 are connected.
- the articulation 4 has one Articulated pin 5 on the one hand with the Unterbeck 2 in is essentially firmly connected and the other one Head 6, the Oberbeck 3 through a bore 7th rotatably holds together.
- For an articulated lash adjuster 8 is the head 6 with an external thread 9 and a corresponding adjusting nut 10 provided. Between the adjusting nut 10 and the Oberbeck 3 is a soft-elastic, arranged first to the head 6 first Ring 11 arranged.
- the self-locking (relative difficult) adjusting nut 10 is for example formed that the external thread 9 of the head 6 with a Circulation groove 13 is provided in which a soft elastic (Rubber-like) second ring 14 is arranged, the Ring 14 occupies part of the external thread and thereby a relative stiffness with the adjusting nut 10 causes.
- This stiffness can be seen in a large Frame by an excess of the diameter of the ring 14 in Specify the ratio to the diameter of the external thread 9.
- the binding must be provided be that the adjusting nut 10 when working with the Scissors 1 do not disconnect themselves from the external thread 9 can adjust, but only by manually adjusting the Adjusting nut 10.
- At least one sliding disc 12 for example made of plastic, preferably made of Teflon.
- two sliding disks 12, 12 arranged one above the other results in an even softer one Cutting feeling with the scissors 1 through a better one Sliding behavior (sliding washer 12 on sliding washer 12 reduces the friction compared to only one sliding washer 12 between ring 11 and a sliding washer 12).
- sliding washer 12 on sliding washer 12 reduces the friction compared to only one sliding washer 12 between ring 11 and a sliding washer 12.
- FIG. 2 A corresponding top view is shown in FIG. 2.
- the second exemplary embodiment according to FIGS. 3 and 4 differs essentially in that the Adjusting nut 15 is sunk into the Oberbeck 3. Thereby becomes, for example, a hooking of hair with the otherwise adjusting nut 10 protruding from Oberbeck 3 prevented.
- the countersunk adjusting nut 10 can be well grip when the diameter of the adjusting nut 10 is equal or is greater than the width of the upper pelvis 3.
- FIGS. 5 and 6 A third exemplary embodiment is shown in FIGS. 5 and 6 shown.
- the difference to the second Embodiment according to Figures 3 and 4 consists in that instead of the circulation groove 13 with the second ring 14 that External thread 9 is provided with at least one transverse bore 18 in which a preferably elastic plastic pin 19 is arranged, the ends of the pin 19 being a part of the external thread 9.
- a preferably elastic plastic pin 19 is arranged, the ends of the pin 19 being a part of the external thread 9.
- the ends of the pin 19 being a part of the external thread 9.
- Depending on the oversize of the ends and choice of material of the pin 19 can be a desired Specify stiffness. This can result in a lower Construction height can be realized because, in contrast, the usable External thread height is not restricted.
