Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a contact portion structure in which a ring-shaped or spiral-shaped convex portion is formed on a contact portion of an article with the skin. Here, the articles include all articles such as cups, ballpoint pens, spectacle frame moderns, baseball bats and golf clubs that are in constant contact with the skin during use.

(Prior Art) FIG. 7 shows a tip portion of a ball-point pen that has been conventionally used. As shown in the figure, ring-shaped concave grooves are arranged and formed in the tip portion of the ball-point pen. By forming the ring groove in this way, it is possible to prevent slippage during writing, but since it is a concave groove, the slip prevention effect is low, and since the ring groove is injection molded with the main body case, the material However, there is also a problem in that the friction coefficient is high only in this portion, and a flexible material cannot be used.

Further, in the case of a glass cup, depending on its shape, it is very difficult to hold, and a cup that slips easily is also frequently used. Similarly, the plastic modern attached to the tip of the temple of the eyeglass frame also comes into contact with the skin and wears the eyeglass when the eyeglass is worn, but if the modern slips and shifts the position. , The glasses I wear also slip off. Of course, a modern is also known in which the contact surface is made uneven to prevent slippage with the skin, but since it is an injection-molded unevenness, the slip prevention effect is not so great. In addition, forming a concave groove on the surface in this way is
In particular, in the case of an article to which bending stress acts, it results in concentration of stress, which causes a phenomenon such as cracking or cracking.

(Purpose of the Invention) As described above, the grip of an article, a handle, and the like are often slippery in places where they come into contact with the skin, and the present invention aims to solve this problem. That is, the present invention provides a contact part structure in which a kind of anti-slip part is formed on the surface in contact with the skin. On the other hand, the anti-slip portion formed on the surface is provided with a cushioning function, sometimes aiming at a decorative effect.

(Structure of the present invention) In order to solve the above problems, the contact portion structure according to the present invention has a ring or a spiral having an uneven cross section formed on the outer surface of the article, particularly on the grip or the handle. The convex cross section is formed with a smooth curved surface, and the convex ring is not formed at the same time as the article body, but is formed and fixed on the surface as a secondary process. Therefore, the material can be arbitrarily selected, and flexible silicone, urethane, epoxy resin, or the like can be used, and a color that is also suitable for the article can be selected and used.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

(Embodiment) FIG. 1 is an enlarged view of the tip of a ball-point pen, in which convex rings 2, 2, ... Are formed at regular intervals on the outer surface of the main body case 1, and are projected from the surface 3 of the main body case 1. Ring 2
Is rising.

As shown in the enlarged view of part A of FIG. 1 in FIG. 2, the cross section of the convex ring 2 is formed by a smooth curved surface, and the surface 3
The boundary area between and is also continuous with a predetermined curved surface. The convex ring 2 is formed as a secondary process on the surface 3 of the main body case 1. For example, the main body case 1 is rotated and applied while flowing out the fluid resin from a small outflow hole. Each time it is rotated, it is moved by a certain distance in the axial direction, spin-coated again, and then cured. The means for hardening may be either forced hardening by heating or natural hardening. Here, the material used for forming the convex ring 2 is not particularly limited, but a flexible material such as silicone resin or urethane resin is generally suitable. An appropriate color is used in consideration of the harmony between the main body case 1 and the head 4.

Figure 3 shows the convex ring 2 on the modern 5 of the eyeglass frame,
2 is an example in which a flexible resin is applied as in the case of the ball-point pen described in FIG. The modern 5 is inserted into the tip of the vine 6 and then bent as shown in the figure, but it is more convenient to apply the convex ring 2 before the vine 6 is attached. is there. The modern 5 is not a circular cross section like a ball-point pen, but is an ellipse or an ellipse, and the size changes along the longitudinal direction. Therefore, in the resin coating process, the outlet of the coating device is rotated along with the rotation of the modern 5. The position of the applicator is controlled to maintain a constant distance from the modern surface.

FIG. 4 shows an embodiment in which convex rings 2, 2, ... Are formed on the outer peripheral surface 8 of the glass cup 7 at regular intervals. As described above, the convex rings 2, 2, ... May be formed not only on a part of the outer peripheral surface 8 but also on the entire outer surface 8, as long as the convex rings 2, 2, ... For example, the area to be formed may be necessarily limited.

FIG. 5 shows an embodiment in which a convex helix 9 is formed on a baseball bat, and a series of convex helix 9 is formed on the outer peripheral surface 11 of the grip 10.
Are formed and have a non-slip effect.

Fig. 6 has many points that it functions as a protective material rather than aiming at the anti-slip effect, but the tea bowls used for tea ceremony are often artistically expensive, and when not used, lacquer finish There are many cases where it is mounted on a pedestal and used as a kind of figurine. However, since the bowl which is a pottery is very hard and the surface of the pedestal is scratched, a convex ring 14 is formed on the lower end surface 13 of the leg 12 so that it can be received not only by the palm but also by the lower end surface of the pedestal. Considering that 13 does not come into direct contact.

Although it can be applied to various things in addition to each of these articles, as described above, the contact portion structure of the present invention is one in which a convex ring or a convex helix is formed on an appropriate surface in contact with the skin. Such an effect can be obtained.

(Effect) (1) The contact portion structure of the present invention is provided on the surface of the required article,
A convex ring or a convex helix is formed by secondary processing, and by using a material having flexibility and a high coefficient of friction as the convex ring or the convex helix, cushioning and slip resistance Exert an effect.

For example, by forming these at the tip of a writing instrument, it does not require undue force and it is very easy to write, and if it is formed into a modern spectacle frame, the worn spectacles do not slip off and it works from the vine. It is also possible to suppress the pain caused by the pressing force applied.

(2) Since the convex ring and the convex helix of the present invention are formed on the surface of an article, the formation of these does not cause cracks or cracks on the surface, and the convex ring has a smooth cross section. Since it is formed of a curved surface and has no corners, it is easy to remove dust and dirt attached.

(3) On the other hand, these convex rings and convex spirals can obtain a decorative effect in harmony with the article body by giving an appropriate color in addition to the functional effects such as slip resistance and cushioning property.
