No- wear scissors for hair cut and the like application occasions

Abstract

The pair of cutting blades are pin joined to each other at their terminal webs which are joined to bow handles. A ball bearing is mounted to the pivot pin by way of an antifriction spacer for providing a permanent spacing between the terminal webs in order to prevent the same from abrasion and consequent uneven wear. A clamp is coupled at one end to the pivot pin projecting from one of the terminal webs, and anchored at another end to the other terminal web, in order to bear the component of cutting resistance which tends to spread the pair of blades in opposite directions away from their parallel planes of motion.

Description

technical field [0001] The present invention generally relates to scissors including those articles generally classified as shearing implements. In particular, the present invention relates to non-abrasive, light-acting, long-life scissors suitable for hairdressing salons or barbershops, which allow cutting and trimming of hair using the latest, up-to-date technology for haircutting, although not necessarily limited to this particular application. Background technique [0002] In the simplest form of man-made tool, scissors consist essentially of two blades with handles connected together by a pin in an intermediate position for pivotal movement in two parallel planes. When the handle is closed, the blades or their precise cutting edges slide past each other to provide the cutting action. When cutting, the blades encounter resistance not only in the direction preventing the handles from closing, but also in the direction of opening the pair of blades in opposite directions...

AI Technical Summary

Problems solved by technology

Scissors with worn contact areas will not provide the well-running, even and clean cut that they would without wear

Of course, uneven wear of the blades can be repaired, or avoided by regular overhauls, but for these purposes the scissors must often be returned to the manufacturer, at the cost of significant time and expense

Local repair services often prove unsatisfactory or even cause damage
