"Thinning scissors" f

The innovation concerns a thinning scissors, the bcjde Scissor basins have a tooth-shaped profile due to recesses running from the cutting edge to the back.

Such thinning scissors with relatively fine teeth, i.e. with 20 or more teeth, have been known for many years.

For some time now have been for special fashion cuts Thinning scissors are also known that have relatively few, i.e. about 5 to 10 teeth, with the gaps between the teeth

, ^ about the same width as the teeth. With these ] Scissors is just a Scherenbeck toothed in this way,

while the other Scherenbeck is either a smooth, continuous cutting edge or a cutting edge with only sghr small depressions opposite the recesses or Has tooth gaps in the other cutting edge.

In the case of certain fashion haircuts, however, it is desirable that the thickest strands of hair ¹ * remain uncut. In this case, it should be avoided that these thick, uncut strands of hair are squeezed when closing the scissors and block or spread them, so that especially in the area of the tip of the scissors cleaner (I * cut is more possible. Also, pulling out

the closed scissors with jammed, uncut; strands of hair painful, although could? Thought about that

to provide their Scherenbeck with recesses. Like this Known from the fine-toothed thinning scissors. Through this There was more space to take in the uncut Hair scissors created, but it has been shown that with thinning scissors, in which both scissor basins wide and have deep recesses or tooth gaps, the elasticity of the scissor basin is so great that a cleaner Cut up to the tip of the scissors is no longer achievable. Furthermore, it has been found that such thinning scissors there is a not inconsiderable risk of breakage, etc. because of the recesses usually made by milling all end on the same line parallel to the back of the Scherenbeck and in this area at the hardening that follows milling by heating and quenching creates stresses in the material.

The innovation is therefore based on the task of creating thinning scissors of the type mentioned at the beginning, which can be provided with a relatively small number of teeth and large gaps to accommodate thick strands of hair, without that as a result, the break resistance of the scissors and the cleanliness of the cut suffer.

This object is achieved according to the invention in that along each cutting edge recesses of greater and lesser depth alternately follow one another and that in each case a recess of great depth in one Scherenbeck is opposite a recess of lesser depth in the other Scherenbeck.

This avoids the formation of a continuous line of weakness parallel to the RÜGken of the Scherenbeck ala also counteracts the risk of elastic bending of the Schererbeck during the cutting process, although much larger gaps are created to accommodate correspondingly thicker strands of hair, more comparable than with thinning scissors that are only toothed on one side Number of teeth is the case.

Especially with such thinning scissors with only relatively few teeth, however, is the desired ease of movement the closing or cutting movement cannot easily be achieved. In other words are already the well-known thinning scissors, in which only one Scherenbeck does not have coarse teeth rarely stiff. According to the innovation, this disadvantage is in a preferred embodiment of the Thinning scissors helped that the lying between the recesses tooth-shaped parts of the Cut at least one of the Scherenbeck's inside with a gap of approx. 3 to 5 mm Undercut starting from the cutting edge and running towards the back of the Scherenbeck exhibit.

In the drawing the thinning scissors are after the Innovation shown, etc. at the top in the open position including a cross-section along the line A-B, and below in the closed position including a cross section along the line C-D.

Both scissor basins 1, 2 have alternating tooth gaps or recesses la or 2a larger Depth and tooth gaps or recesses Ib or 2b of lesser depth between the remaining ones Cutting parts or teeth Ic or 2c. The succession the recesses of one Scherenbeck, however, are opposite to those of the other Scherenbeck offset by one step, so that in each case a recess of great depth in one of the Scherenbeck recesses opposite to the shallower depth in the other Scherenbeck. In this way it is achieved that in When the scissors are closed, large gaps for picking up thick strands of hair remain, but that pro Scherenbeck the length of the areas with the smallest material cross-section (i.e. the added width of the recesses great depth) is less than half as large as it would be,

When creating large gaps, recesses throughout * The large gaps thus created are in the direction of the The longitudinal axis of the scissors is alternately slightly offset from one another laterally. The desired ease of movement becomes achieved by the undercut recognizable in the section A-B at the angle oi, which is at least one Scherenbeck, but is preferably provided on the inside of both scissor basins 1 and 2 (see section C-D), etc. so that the relief is only in one certain distance of, for example, 2 to 6 mm from the cutting edge - or in the area of the recesses from the imaginary cutting edge - begins and extends to the back of the

relevant Scherenbeck runs. 15th

Claims (2)

Protection claims 1. Thinning scissors, the two scissors basins have a tooth-shaped profile due to recesses running from the cutting edge to the back, characterized in that along each cutting edge recesses of greater and lesser depth alternately follow one another, and that in each case a recess of great depth (la) in the one Scherenbeck ( 1) a recess of lesser depth (2b) in the other Scherenbeck (2) opposite. overrides. 2.
