Multi-cutting hairdressing scissors with internal spring-loaded mechanism and thumb ring activation

Abstract

This invention relates to a professional hairdressing scissors that is capable of performing several consecutive cuts mechanically, in addition to the normal function of opening and closing the blades, with the help of an internal spring-charging mechanism, without the need for electricity or a motor. In these scissors, energy is stored by an internal torsion spring and is charged by the natural movement of the hairdresser's hand during work. The compressed spring is placed in the standby state by a retaining latch. The mechanism is activated with just a twist or a small tap on the thumb ring, releasing the latch and initiating rapid movement of the movable blade. As a result, the blades open and close several times in succession, allowing for fast, even, and precise cuts. The scissors are designed in such a way that all the components of the mechanism are hidden inside the body, and their appearance remains completely similar to that of ordinary hairdressing scissors.

Description

Description of the invention Title of the invention Multi-blade hairdressing scissors with internal spring-loaded mechanism and thumb ring activation Technical background of the relevant invention This invention falls into the field of hand-held cutting tools and hairdressing equipment, and specifically relates to the structure and operating mechanism of professional hairdressing scissors. The technical field of this invention includes mechanical motion transmission mechanisms, spring energy storage systems, conversion of rotary motion into reciprocating motion, and the design of hand-held tools with multi-stage operation capability. This invention helps to improve the technology available in hairdressing scissors and improve the speed, quality, and accuracy of the hair cutting process, and is classified as a mechanical tool without the need for electrical energy. Technical problem and stating the objectives of the invention Existing hairdressing scissors are only capable of making one cut per opening and closing of the blade, and all cutting operations depend on the hand strength and physical skill of the hairdresser. In many hairdressing techniques, making fast, uniform, and consecutive cuts is of great importance, but existing tools do not provide such a capability. Increasing the speed of work is usually accompanied by increased hand fatigue and decreased accuracy, because the hairdresser is forced to constantly repeat the opening and closing motion of the scissors to make consecutive cuts. Also, in existing scissors, there is no possibility of storing mechanical energy and its controlled release without the use of electricity or a motor. The purpose of this invention is to provide hairdressing scissors that can make multiple quick cuts with just a small movement of the thumb ring, reduce the hairdresser's hand fatigue, increase the speed and uniformity of cutting, and at the same time remain similar to the appearance and use of conventional scissors. A description of the state of the prior art and the history of developments related to the claimed invention. Conventional hairdressing scissors are based on a simple mechanism of manually opening and closing the blades and do not have any energy storage system or internal mechanism to make quick and consecutive cuts. In some hand tools, a spring is used only to return the blade to its original position, but these structures are not capable of making multiple cuts in a row. Tools equipped with motors or ratchet systems are also not suitable for delicate hairdressing applications due to their large size, high weight and the need for external energy. In previous technologies, a structure that can store the mechanical energy from the natural operation of the scissors in an internal spring and then release it with just a small movement of the thumb ring is not seen. Therefore, an innovative solution is needed to increase the speed and efficiency of hairdressing scissors. Providing a solution to an existing technical problem along with an accurate, sufficient, and integrated description of the invention In this invention, a fully mechanical and compact mechanism is built into the body of the scissors that is capable of storing and releasing mechanical energy. This mechanism includes a torsion spring, a charging gear, a retaining latch, and a motion transmission member. The mechanical energy resulting from the natural opening and closing of the scissors during normal use is gradually stored in the torsion spring. After charging, the spring is held in a ready-to-use state by the latch. By applying a limited movement or a small blow to the thumb ring, the release lever is activated and the latch is released. As a result, the energy stored in the spring is released and transferred to the movable blade through the motion transmission member, causing the blade to open and close quickly and continuously. All components of the mechanism are designed to be located inside the body of the scissors and do not affect the appearance and normal use of the tool. Explanation of shapes, maps and diagrams Figure (1) shows a side view of a barber's scissors in its normal position, showing the fixed blade, movable blade, central axis, finger rings, and little finger rest. Figure (2) shows a cutaway view of the internal mechanism of the scissors, showing the spring charging components, retaining latch, and motion transmission system. Figure (3) shows how to activate the multi-cutter mechanism, showing the internal release lever, the activation protrusion on the thumb ring, and the path of movement of the thumb ring. A clear and precise statement of the advantages of the claimed invention over prior inventions. The present invention is capable of performing multiple rapid and consecutive cuts without the need for electricity or a motor. Its internal mechanism is completely hidden inside the body and the appearance of the scissors remains similar to that of ordinary scissors. This structure increases the speed and uniformity of cutting, reduces the fatigue of the hairdresser's hand and increases the efficiency of professional work, while previous tools lack such capabilities. Description of at least one implementation method for implementing the invention The scissors according to the present invention are normally used by the hairdresser and during the normal opening and closing, the spring charging mechanism gradually stores energy. After charging, the hairdresser can activate the multi-cutting mechanism with just a small movement of the thumb ring, if necessary, and perform several quick and consecutive cuts, without having to manually repeat the opening and closing motion of the scissors. Explicit mention of the industrial application of the invention This invention can be used in the hairdressing and hairdressing industry as a professional cutting tool and has the capability of mass production in the hairdressing tool manufacturing industry.

Claims

Complaint What is claimed: Claim 1) 1. Multi-blade barber scissors consist of a fixed blade and a movable blade connected to each other by a central axis and have a completely mechanical internal mechanism for charging and releasing energy, including a torsion spring, a spring retainer, and a motion transmission member, in such a way that the mechanical energy resulting from the normal operation of the scissors is stored in the spring, and by activating the release mechanism through the thumb ring, the stored energy is released and causes rapid and continuous movement of the movable blade.
