Description
Background and Summary of the Invention
The present invention relates to a haircutting angle indicator for use with scissors or the like.
Previously, barbers have relied on eye measurement to hold the scissors at a desired angle during haircutting work. This conventional way requires a great deal of skill to perform correctly.
It is an object of the present invention to provide a haircutting angle indicator which is adapted to be mounted on scissors or the like and is very helpful for quick, accurate haircutting.
The haircutting angle indicator according to the present invention are provided with an angle gauge with which the barber can hold the scissors easily at any desired angle. With the invention, haircutting can be expedited and performed correctly.

Detailed Description of the Preferred Embodiments
Referring now to FIGS. 1 and 2, the first embodiment of the present invention includes an attachment 1 removably secured to the handle of the scissors A by means of screws. A square hole 2 is formed in the attachment 1 to receive a square bar 3. The square bar is provided with an axial opening or hollow 4 on one end thereof and with a tripod 5 on the other end. A disk-shaped angle gauge 6 provided with a leg 7 is adapted to rotatably fit in the top hollow 4 in the square bar.
The angle gauge 6 is provided with a needle 8 loosely mounted on a pivot 9 provided in the center thereof. By the force of gravity, the needle 8 is adapted to point vertically downward at all times. The angle gauge 6 is marked with two sets of graduations which indicate angles measured both clockwise and counterclockwise from the zero point 10 in the center.
The square bar 3 is marked with graduations to indicate the height of the scissors from the head when the feet of the tripod 5 is put on the head of a person who is having her hair cut. At the position where each of these graduations is marked, a transverse hole 11 is provided in the square bar 3.
The first embodiment of the present invention further includes a projection 12 which is of an inverted L-shape. When the square bar 3 is mounted in the square hole 2 in the attachment 1, the end of the projection 12 is adapted to fit in one of the holes 11 to determine the height of the scissors.
In use, the square bar 3 is firstly mounted in the square hole 2 in the attachment 1. Then the projection 12 is fitted in one of the holes 11 to prevent rotation of the attachment 1 relative to the square bar 3 and to set the scissors A at a desired height from the head of a person. When a barber wishes to cut the hair at a desired angle during the haircutting work, he has only to incline the scissors A until the needle 8 comes to the desired angle.
Referring now to FIGS. 3, 4 and 5, the second embodiment of the present invention differs from the first one in that the angle gauge 6' is mounted on the haircutting scissors A by means of an angle gauge holder 16, which is provided with a square-headed portion 17 on one end and with an opening or hollow 18 on the other end. On the latter end, the angle gauge holder 16 is marked with graduations 19 which represent angles measured in both directions from a zero point and provide an indication of the angle of the cutting direction about the pivot axis of the scissors. The zero point 10 on the angle gauge extends downwardly into an extension line. The square-headed portion 17 is adapted to fit in the square hole 2' in the attachment 1'. Rubber bands 20 fit on the leg 7' of the angle gauge 6'. The leg with the rubber bands is adapted to fit in the hollow 18 in the holder 16.
The second embodiment of the present invention still further differs from the first one in that on both sides of the angle gauge 6' are provided a needle 8 and graduations.
In use of the second embodiment, the square-headed portion 17 of the angle gauge holder 16 is mounted in the square hole 2' in the attachment 1'. Then a setscrew 21 is tightened to fasten the angle gauge holder 16. Then the leg 7' of the angle gauge 6' is put in the hollow 18 in the angle gauge holder 16. As long as excessive turning force is not applied to the angle gauge 6', movement of the angle gauge relative to the angle gauge holder 16 is prevented by friction caused by the rubber bands 20.
FIG. 6 shows a case where a barber holds the scissors A with the angle gauge 6' disposed above the scissors.
FIG. 7 shows how the hair is cut obliquely downward or upward at a desired angle .theta..sub.1 and .theta..sub.2. Firstly the scissors A is held so that the graduation 19 on the angle gauge holder 16 points the desired angle .theta..sub.1 (e.g. 45.degree.). Then the scissors is gradually inclined to an angle of .theta..sub.1 on the angle gauge with the holder 16 at a horizontal position and the angle gauge at a vertical position. Further, the hand is twisted so that the needle 8 on the angle gauge 6' will point to an angle .theta..sub.2 (e.g. 135.degree.). Now the scissors will be at the desired position.
If a barber looks askance at the scissors A while haircutting, the angle gauge 6' can be turned about the axis of the leg 7' until the extension line from the zero point comes to such a graduation on the holder that he can see the angle gauge easily. The indicator of the present invention may be used with a haircutting razor as well as with scissors.
While two embodiments of the present invention have been disclosed, it is to be understood that they are described by way of example only and not in a limiting sense, various other modifications being apparent from the above description.
