Description

An improved structure of a brush}

The present invention relates to an improved structure of a handle, that is, a handle structure of a hand-held tool such as a toothbrush, a carving knife, and the like. The present invention is user-friendly with less force and improved structure, and the design of the structure is also very practical as it is designed for each finger position.

In everyday life, a tool using a handle has a use part and a handle part, and examples thereof include a toothbrush, a shoe brush, a knife, a fruit knife, and a carving knife. For example, a toothbrush that is generally used, for example, only a toothbrush or handle pattern and shape are considered seriously. Because of their strength, they put a strain on the wrist and sometimes cause the toothbrush to fall out of the finger or a very painful wrist. This is one of the drawbacks of toothbrushes with long handles that are commonly used. In addition, in the case of commonly used shoe brush, there is no handle so shoe polish can be easily reached. Conventional structures also have the inconvenience of not being portable due to the long handles in addition to the drawbacks mentioned above.

Commonly used toothbrushes, for example, general toothbrushes only care about the shape and shape of the bristles or handles, but they are often inconvenient to use because they do not consider the width of the handle and the area where the palm contacts. Relying on the power of the wrist will strain the wrist and sometimes cause the toothbrush to fall out of the finger or hurt the wrist. The above is a shortcoming that is commonly experienced with toothbrushes with long handles. Also, in the case of a conventional shoe brush, the shoe polish can be easily reached because there is no handle. In addition to these drawbacks, there is an inconvenience that can not be carried due to the long handle.

Accordingly, the present invention is directed to providing an improved toothbrush structure of a handle that grips such a multipurpose tool. The construction of the present invention will be described below with reference to FIG. 1 with one embodiment attached as follows. First, second, third projections 11, 12, and 13 are formed in the front, middle, and rear subdivisions of the upper surface of the handle 10, respectively, with the first and second concave surfaces therebetween. (18) and (19) are formed. Furthermore, on the lower side, the fourth and fifth protrusions 14 and 15 are formed opposite the first and second protrusions 11 and 12 on the upper side, and a third concave surface 18 'between them. ) And a grip 16 as the first support at the lower middle back of the handle.

If flattening the use section 20, the bristle 21 comes to this part, and this part can come with the desired ones according to its purpose. In the case of a carving knife, the blade of the carving knife will come to this part. And the bristle is inclined at 45 degrees to the front portion 20, the area of the bristle is small, the length is long, because the bristle is a relatively hard bristle bristle (22), this area in a small range or brushing inconvenience You can use

Referring to FIG. 2, the thumb is placed on the second concave portion in the form of wiping dentures, and the index finger and middle finger come between the first support portions 16 to further tighten the handle.

According to Figures 3 and 4, if using the inclined bristle (22) of the handle 10, the middle finger and the ring finger comes between the holding portion 16 as a support portion and the index finger comes to the third concave surface (18 '), The thumb is gripped by the handle 10 in such a way as to come to the first surface 18, or when only the thumb and the index finger are used, the thumb and index finger remain when the first and third surfaces 18 and 18 'are released. Three fingers come to the handle part.

In addition, the bottom end of the handle 10 makes the grip portion 17 as a second support portion, the shape is slightly curved to look so that the finger or pinky finger can come here, but brushing more comfortably You can do In the small hole 171 on the lower surface of the second gripping portion 17, a pointed rod 30 can be inserted to remove dirt caught between teeth when wiping the denture.

The first and third concave surfaces 18 and 18 'of the handle 10 may be curved surfaces 181 and 181' to prevent the thumb or index finger from sliding to the side.

In addition, the middle portion of the handle 10, the second concave surface 19 is made into a long groove 191, the thumb presses the second concave surface 19 when the skin of the thumb enters a long portion between the 191. It is a structure that prevents slipping because it plays a fixed role.

According to Figure 5, the use portion 20 of the present invention can be formed in accordance with the purpose of different uses, respectively, and other tools can be replaced in place of the toothbrush. The drawing is a drawing when a knife comes.

The present invention is designed by ergonomically designed toothbrush (handholding tool), so it can be easily held by hand, and it has the advantage of being able to hold more tightly with less force, which is convenient and reliable for children, the elderly or patients. The handle is shorter than usual and convenient to carry.
