  Hereinafter, a specific configuration of the present invention will be described in detail with reference to the drawings. First, FIGS. 1 to 3 show a first embodiment of a portable communication terminal one-handed operation assisting device according to the present invention. A mat body molded from rubber, synthetic resin, thermoplastic elastomer (preferably styrene thermoplastic elastomer or urethane thermoplastic elastomer), and other substances having both adhesive force and elasticity, and a portable communication terminal (P ) In an arbitrary outline shape (a square of 50 mm × 25 mm in the illustrated example) smaller than the rear surface (11) of the multifunctional mobile phone commonly called a smartphone.

  The thickness (t1) of the mat body (10) is set to be greater than 0.5 mm and less than the thickness (T) of the portable communication terminal (P) to be used for attachment, preferably within the range of 2 mm to 5 mm. To do. Even if it is thinner than 0.5 mm, the fingertip of the operating hand can adhere to the surface of the mat body (10) in a non-slip state, but it cannot withstand the resistance (friction resistance) of the fingertip and is torn. It is inappropriate because of fear.

  On the other hand, if it is thicker than the thickness (T) of the portable communication terminal (P) to be used for pasting, it will become unnecessarily large and bulky in the state of being used for pasting to the portable communication terminal (P). It is difficult to store and carry stably. Therefore, it is most preferable to set the thickness from 2 mm or more to 5 mm which is thinner than the thickness (T) of the mobile communication terminal (P).

  In addition, you may shape | mold the said mat body (10) in the same magnitude | size and outline shape as the back surface (11) of a portable communication terminal (P). In addition, the mat body (10) is given various colored colors such as white, yellow, blue, black, and metal at the time of molding, is given a colorful pattern, or the mat body (10) is made transparent or translucent. May be.

  Then, a masking (protection) sheet (12) preferably made of a transparent or translucent synthetic resin film is bonded and integrated on the surface of the mat body (10) by its own adhesive force. Non-adhesiveness and smoothness are imparted to the surface of the mat body (10). The thickness (t2) of the masking sheet (12) is, for example, 25 μm to 50 μm, and may be set thinner than the thickness (t1) of the mat body (10).

  (13) is a plurality of fingertip insertion holes distributed in the masking sheet (12), and the fingertips of the operating hand inserted therefrom can be adhered to the surface of the mat body (10) in a non-slip state. It is like that. In this respect, in FIGS. 1 to 3, a total of three fingers of a size that can insert any three fingers except the thumb among the five fingers in the operating hand (one hand) are distributed in a circle, but the fingertip of one hand is inserted. As long as the size and shape can be achieved, for example, it may be one oval or two or four or more.

  In that case, the unfinished die-cutting piece in a dotted line state as shown in FIG. 4 or a half-cut state in which the fingertip insertion hole (13) opened in the masking sheet (12) can be completely removed by the fingertip later. It is desirable to close in advance according to (14). This is because it is possible to prevent the surface of the mat body (10) from being exposed through the fingertip insertion hole (13) of the masking sheet (12) and easily attaching and fouling dust.

  On the other hand, on the back surface of the mat body (10), a separate adhesive (15) preferably stronger than its own adhesive strength is used, for example, a paper having a thickness of about 0.5 mm or a synthetic resin film in units of microns. The release sheet (16) made of is peeled off during use, and can be attached and fixed to the back surface (11) of the portable communication terminal (P).

  However, such a release sheet (16) may of course be bonded and integrated on the back surface thereof by the adhesive strength of the mat body (10) itself. As the release sheet (16), the same synthetic resin film as the masking sheet (12) in which the fingertip insertion hole (13) does not open can be adopted.

  1st Embodiment of the one-handed operation assistance tool which concerns on this invention is provided with the said structure, It can provide to a market as a sales goods which packed the plurality in one set, and the user who purchased this uses it. In this case, the release sheet (16) is peeled off from the mat body (10), and the adhesive (15) or the mat body (10) itself has the adhesive strength of the mobile communication terminal (P). What is necessary is just to stick and integrate to a back surface (11). In this regard, in FIG. 3, a rectangular mat body (10) smaller than the portable communication terminal (P) is attached and fixed to the center of the rear surface (11) of the communication terminal (P).

  Then, from the fingertip insertion hole (13) of the masking sheet (12) imparting non-adhesiveness and smoothness to the surface of the mat body (10), for example, the middle finger (F1) of one hand as shown in FIGS. And the ring finger (F2) and the little finger (F3) are inserted, and the fingertips are all adhered to the surface of the mat body (10).

  Then, since these three fingertips are kept in a non-slip state with adhesive force, even if the lateral width (W) of the body in the portable communication terminal (P) is wide, the back surface (11) It is possible to securely hold a single width from the center of the hand with the above-mentioned fingertip of one hand, and the thumb (F) remaining on one hand is moved upward (front side) to the screen (17) of the portable communication terminal (P) As a result, the target part of the screen (17) can be touched smoothly over a wide range.

  In that case, the surface of the mat body (10) may be elastically deformed by receiving the fingertip of one hand, but since it is restored when the fingertip is released, it does not hinder repeated use. It is also possible to peel off from the back surface (11) of the mobile communication terminal (P) and replace it with a new one-handed operation assisting tool.

  In FIG. 3, a smaller rectangular mat body (10) is attached to the center of the back surface (11) of the portable communication terminal (P), but the attachment site is selected as desired by the user. be able to. Further, the size and contour shape of the mat body (10) are formed the same as those of the back surface (11) in the portable communication terminal (P) as shown in FIG. 10, and the entire back surface (11) is formed. It is also possible to use it by pasting.

  In particular, as suggested in FIG. 11, the large mat body (10) surrounds not only the rear surface (11) of the mobile communication terminal (P) but also the front / rear surface and the entire left and right side surfaces. By sticking and using as described above, it is possible to protect the mobile communication terminal (P) from physical shocks or scratches that are accidentally received. Further, the mat body (10) is attached to the whole or a part of the rear surface of the protective cover (18) made of rubber or synthetic resin that protects the mobile communication terminal (P) from physical impact as shown in FIG. May be used.

  Next, FIGS. 13 and 14 show a second embodiment of the one-handed operation assisting device according to the present invention. In this embodiment, the mat body (10) is made of acrylonitrile butadiene rubber (NBR) and polypropylene glycol having adhesiveness and elasticity. (PPG), the same size and outline shape as the back surface (11) of the multifunctional mobile phone which is also commonly called a smartphone in the mobile communication terminal (P), or the back surface ( It is created in an arbitrary contour shape smaller than 11).

  Moreover, the mask body (12) having the fingertip insertion holes (13) as in the first embodiment is not bonded to the surface of the mat body (10), and the surface is exposed. However, the surface of the mat body (10) has adhesive strength as a surface treatment film (19) by surface degreasing and surface oxidation with a solvent, surface roughening, adhesion of powder, adhesion of silicone resin, and other methods. It is in a smooth state that has been lost or weakened, and has the same non-adhesiveness and smoothness as the masking sheet (12) of the first embodiment.

  Then, one piece which is depressed by a certain depth (d) from the smooth surface treatment film (19) having no or weak adhesive force on the surface of the mat body (10) toward the inside of the mat body (10). Alternatively, a plurality of fingertip insertion grooves (20) are cut out. Since the inside of the concave groove (20) is exposed as a notch surface (cut surface) of the mat body (10), the mat body (10) itself exerts its adhesive force.

  As a result, if the fingertip of one hand is inserted here, the fingertip can also be fixed and maintained in a non-slip state by the adhesive force of the mat body (10) itself, which is accompanied by the configuration of the first embodiment. An effect equivalent to the effect can be obtained.

  Furthermore, in any of the first and second embodiments, the mat body (10) of the one-handed operation assisting tool is a relatively thin flat plate body having elasticity, and the adhesive surface is the first. Since it is secured on a non-adhesive smooth surface by the masking sheet (12) of the first embodiment or the surface treatment film (19) of the second embodiment, it is very easy to handle and is attached to the mobile communication terminal (P). It is convenient because it can be safely stored inside clothes pockets and bags even when used.

  A release sheet (16) made of a synthetic resin film or paper is attached to the back surface of the mat body (10) by the adhesive strength of the mat body (10) itself or via a separate adhesive (15). For example, the attachment and separation of the attachment to the back surface (11) of the mobile communication terminal (P) are substantially the same as the configuration of the first embodiment. The thickness (t3) of the surface treatment film (19) that gives non-adhesiveness and smoothness to the surface of the mat body (10) is the same as the thickness (t2) of the masking sheet (12) shown in the first embodiment. Set it. The same applies to the depth (d) of the fingertip insertion groove (20).
