Abstract

The present invention relates to a handle of a cosmetic scissors, and the opening is made of a hole grip (thumb grip) (8) and a finger ring grip body side (9) for attaching a thumb to the handle of the scissors By reducing the overall weight of the handle of the scissors, the operator can reduce the burden on the weight of the scissors when the scissors open and close the scissors. Also, by creating an opening in the side of the handle, the area to be processed is reduced, which reduces the processing time of the handle when the scissors are manufactured. Is significantly shortened and drilled deeply to the thumb grip (2) where the thumb is inserted when machining the stopper (5), which controls the depth of engagement of the tip of the scissors. Because it does not have to be drilled deeply, it can significantly reduce the grinding time of the scissors. This prevents occupational diseases such as fingers, arthritis and fifty dogs.

There are three types of hairdressing scissors: straight handle, camel style handle, and offset set handle.

The first straight handle, also known as eyeglass type, has the same length between the thumb grip and the ring finger grip on the pivot screw, the pivot axis of the scissors. The model was created in the 1960s, when hairdressers were in the early stages.It is the most powerful type of cutting scissors that can be opened and closed on the principle of the lever, but the cutting power is excellent. Due to the difference in the length of the finger, it is characterized by the fact that the opening and closing of the scissors does not open slightly.

Secondly, the camel style handle, also called the semi offset hand, is the connecting leg that connects the pivot screw, which is the central axis of the scissors, to the finger grip of the ring finger. The shank part looks like a camel's back, so it's called a camel style handle.

In the camel-style handle, the distance between the thumb finger and the finger grip is longer than the thumb grip distance from the pivot screw, which is the central axis of the scissors. It is suitable for the style of hairdressing scissors used to cut, so it is possible to open and close the scissors.

Third, the offset set handle is the thumb grip connecting leg, compared to the distance between the finger grip and the pivot finger of the pivot screw, which is the central axis of the scissors. (shank) The part distance is quite short and is made in a line with the scissors blade, pivot screw and the middle part of the ring finger finger. The biggest advantage is that you can open and close the scissors.

Like this, there are three handles of scissors, and the change of design is given by changing the handles of various scissors in three models.

Conventional handles with scissors have an opening in the handle of the camel style, such as a camel, and a bent part that connects the shank and thumb and ring finger. The weight of the scissors is reduced by making an opening in the upper part of the scissors and two parts of the collar, the hooking neck, and the stopper part, and the thumb in the case of the straight handle. The joint where the thumb grip and the finger grip intersect and the shank leg meet. The opening is made in the upper part only in the two parts of the neck, and the offset set handle In the case of the straight handle, as well as the thumb and finger ring fingers that connect the shank legs of the thumb grip where the two necks meet An opening was made from the top of the bay.

This scissors has an opening on the side of the handle of the scissors to apply for a patent, and the hairdressing scissors have a ring-linked neck where the thumb grip and shank leg fit the existing thumb and the ring finger. (neck) If the opening is made only at the connection part, the weight of the scissors in the handle part is limited and the volume is limited, and the processing time is short, while the opening at the side of the handle of the scissors is small. In the case of making the part, the part and the quantity that can reduce the weight are increased, which makes it possible to cut the time of scissors processing considerably, and also reduce the material cost, and also by making the opening on the side of the handle of the scissors The design part also has the advantage of improving.

An opening is made in the outer side of the thumb grip of the scissors and an opening is made in the inner side of the thumb grip of the thumb. It also creates an opening on the side of the stopper that controls the depth of engagement at the end of the blade.

In addition, an opening is made in the side of the shank portion connecting the thumb grip and the finger grip of the ring finger.

An opening is made in the outer side of the finger grip to insert the ring finger, and an opening is made in the inner side of the finger grip to insert the finger.

In addition, openings are also made on the side of the finger brace to increase the stability of the scissors when opening and closing the scissors.
When making the opening of the handle, make a mold to pour the mold called mold, and make the mold according to the measured shape after making 3D stereoscopic measurement. When the core part is inserted into the mold and the external handle is made by pouring the mold into the mold, it is possible to make a scissors handle with an opening in the mold part. .

If you make an opening on the side of the scissors handle, you can considerably reduce the weight of the scissors handle, which can significantly reduce the time of polishing of the handle during the scissors manufacturing process. It is possible to produce scissors by quantity, which can bring about material cost reduction of raw materials of iron.

The operator using the lightly made scissors can prevent occupational diseases such as fingers, arthritis and fifty dogs caused by using the scissors for a long time, and improve the design part by making the opening. There is this.
