In order to improve nail beauty skills, a hand model (hereinafter referred to as a "hand model") that satisfies a predetermined standard is necessary. In addition, when using a hand model in a practical test for skill evaluation, it is particularly important from the standpoint of fairness and fairness that it satisfies a predetermined standard. The present invention has been made in view of such circumstances. The aim is to provide a hand model that meets predetermined criteria.

A hand model according to an aspect of the present application comprises a cylindrical wrist, a flat instep connected to the wrist, and a plurality of bar-like members extending from the flat instep in a direction opposite to the wrist. It includes fingers, a nail tip removably attached to the end of each finger, and a certification label.

According to one aspect of the present application, it is possible to provide a hand model that satisfies a predetermined standard.

Embodiments will be described below with reference to the drawings. FIG. 1 is a perspective view showing an example of a hand model. The hand model 1 includes five finger portions 11 , an instep portion 12 , a wrist portion 13 and a base portion 14 . When using the hand model 1, the nail tip 2 is attached to the tip of each finger part 11. - 特許庁

Each finger 11 is rod-shaped. Each finger 11 has a structure in which a metal core (not shown) is wrapped in resin. It is desirable that the resin has a texture and feel similar to that of human skin, and is formed of rubber, polyvinyl chloride, thermoplastic elastomer, or the like. Each finger part 11 has the flexibility to be bent by applying a slight force to the hand model 1 and the shape retainability to keep the shape as it is. To achieve this, for example, the core is made of aluminum wire with a thickness of 1 to 3 mm. The core may be omitted as long as the required flexibility and shape retention can be obtained. The five finger parts 11 are different in length and thickness, and imitate a human thumb, index finger, middle finger, ring finger and little finger.

The back part 12 imitates the back of the hand and the palm of the hand. The wrist part 13 has a cylindrical shape and imitates a human wrist. A certification label 3 is attached to the base portion 14 . The certification label 3 indicates that the hand model 1 and the nail tip 2 are models that satisfy a predetermined standard and have been certified by a certification organization. The accreditation body is independent from the manufacturer of the hand model 1 and nail tip 2 . The certifying body inspects whether the hand model 1 and the nail chip 2 meet predetermined standards from a neutral and impartial standpoint. Note that the certification label 3 may be attached to the wrist portion 13 . A certification number is printed on the certification label 3 . The certification number may be represented by a barcode or two-dimensional code and printed on the certification label 3 .

FIG. 2 is a perspective view showing an example of a tip of a finger. The nail bed portion 111 is a portion covered with the nail tip 2 . The side nail contour portion 112 is a portion that contacts the longitudinal side portion of the nail tip 2 . The rear nail fold 113 is the tip of the portion where the nail tip 2 is fixed. The nail epithelial portion 114 is a thin cloth extending from the rear nail fold portion 113 in the distal direction. The epithelial portion 114 of the nail is a portion imitating a so-called cuticle or cuticle.

Nail chip 2 is an artificial nail. The nail tip 2 has a rectangular shape with rounded corners in plan view. The cross section of the claw tip 2 is arcuate. The nail tip 2 is made of, for example, nylon resin, ABS resin, acrylic resin, or the like. The nail tip 2 has multiple sizes. For example, three sizes of S, M, and L are attached to the finger portion 11 and used as S for the little finger, M for the index finger, middle finger and ring finger, and L for the nail of the thumb. The size of the nail tip 2 is not limited to three. Five sizes of nail tips 2 corresponding to each finger may be produced.

FIG. 3 is an explanatory view showing how the nail tip is attached to the finger. One longitudinal end of the nail chip 2 is inserted from between the nail bed portion 111 and the nail epithelial portion 114 . A space in which the nail tip 2 is accommodated is formed in the lower inside of the rear nail contour portion 113, and the nail tip 2 is tentatively fixed. Double-faced tape is applied to the nail bed portion 111 or an adhesive is applied before inserting the nail chip 2 into the nail epithelial portion 114 so that the nail chip 2 can be securely fixed. The nail chip 2 may be fixed using a material other than the double-sided tape and the adhesive as long as the nail chip 2 can be securely fixed.

Next, the specifications required for the hand model 1 will be described. FIG. 4 is an explanatory diagram showing the state of skin-up and skin-down. FIG. 4A shows the appearance of skin-up. Skin-up means pushing and pulling the back nail fold of the finger toward the base of the finger (in the direction of the wrist). This makes it easier to treat nail epithelium hidden in the posterior nail fold. In the hand model 1, the material constituting the back nail fold 113 has the same softness as human skin and is elastically deformable so that the practice of skin-up can be performed.

FIG. 4B shows the state of skin-down. Skin down deforms the lateral nail fold by applying a downward force to the lateral nail fold, exposing the side of the nail plate (longitudinal side) that normally contacts the lateral nail fold. be. This makes it possible to care for the sides of the nail plate more easily. In the hand model 1, an elastic body having the same softness as human skin and being elastically deformable is adopted as the material constituting the side nail fold 112 so that the practice of skin-down can be performed.

FIG. 5 is a side view showing an example of a finger attached with a nail tip. In the hand model 1 shown in FIG. 5, the thin film 4 is attached on the nail tip 2 after the nail tip 2 is attached. The thin film 4 is in the form of a seal with one surface being an adhesive surface. In FIG. 5, the thin film 4 is drawn thick so that it can be visually recognized. The thin film 4 has a thickness smaller than that of the nail epithelial portion 114 or a thickness equivalent to that of the nail epithelial portion 114 . The thin film 4 imitates the keratinous part of the nail epithelium (also called loose cuticle), which is a part of keratin generated from the nail epithelium and attached to the surface of the nail plate. Since the thin film 4 is thin and difficult to handle, an auxiliary film may be attached to the upper surface of the thin film 4 when it is not in use and is attached to a backing paper. When the thin film 4 is attached to the nail chip 2, the thin film 4 to which the auxiliary film is attached is peeled off from the mount and attached to the nail chip 2.例文帳に追加Then peel off the auxiliary film. The auxiliary film enables the thin film 4 to be attached to the nail chip 2 without wrinkling. The thin film 4 may be formed by applying a liquid resin or the like. The thin film 4 may be formed on the nail tip 2 in advance, or may be formed after the nail tip 2 is attached to the finger portion 11 . For example, the thin film 4 is formed as follows. A thin film 4 can be formed by thinly applying a resin dissolved in a volatile solvent to the surface of the nail tip 2 with a brush or the like and drying it. Alternatively, the thin film 4 can be formed by thinly applying a liquid ultraviolet curable resin to the surface of the nail tip 2 with a brush or the like and curing the resin with ultraviolet rays. The thin film 4 may be formed by other methods as long as the cuticle of the nail epithelium can be reproduced, or the thin film may be formed of a material other than resin.

Since the thin film 4 imitates nail epithelial keratin, it is formed of a material having a lower hardness than the nail tip 2.例文帳に追加This is to enable practice of treatments called push-up and push-back for pushing up the keratin of the nail epithelium toward the nail epithelium. This is because it is desirable that the surface of the nail tip 2 after practicing push-ups and push-backs is not excessively damaged.

The hand model 1 according to the present embodiment configured as described above has the following effects. It has sufficient functions as a practice tool for improving skills related to nail beauty. In addition, the hand model 1 can be used to perform skin-up, skin-down, push-up, push-back, and other treatments in the same manner as those applied to human hands and nails, so skills related to nail beauty can be evaluated. Satisfy the prescribed criteria that can be used in the certification practical test. And it has a certified label 3 indicating it.

The technical features (components) described in each embodiment can be combined with each other, and new technical features can be formed by combining them.
The embodiments disclosed this time are illustrative in all respects and should not be considered restrictive. The scope of the present invention is indicated by the claims of the utility model registration rather than the above-mentioned meaning, and is intended to include all changes within the meaning and range equivalent to the claims of the utility model registration. In addition, the scope of claims for utility model registration uses a format in which claims referencing two or more other claims (multi-claim format), but is not limited to this. It may be described using a format for describing multiple claims (multi-multi-claims) that cite at least one multiple claim.
