Description

  The present invention relates to a protective film suitable for protecting the surface of an object to be protected such as a rubber surface of a table tennis racket from dirt.

  The dirt on the rubber surface of the table tennis racket may adversely affect the rotation of the hit ball. Therefore, when the table tennis racket is not used, a protective film 3 is attached to the rubber surface 2 of the table tennis racket 1 as shown in FIG. 3, thereby protecting the rubber surface 2 from dirt. By the way, this kind of protective film 3 is generally made of a synthetic resin sheet such as PE (polyethylene) having an adhesive layer formed on one side, and is called “adhesive rubber film” or the like and is commercially available at sports equipment stores. ing.

  Specifically, the protective film 3 is a sheet-like separator (not shown) attached to the surface of the adhesive layer of the protective film 3 after removing dirt on the rubber surface 2 of the table tennis racket 1 with a dedicated cleaner. Z)) and is attached to the rubber surface 2 of the table tennis racket 1. At this time, the protective film 3 is matched to the shape of the rubber surface 2 by cutting off the portion protruding from the rubber surface 2 of the table tennis racket 1 using scissors or a cutter. When the table tennis racket 1 is used, the protective film 3 is peeled off from the rubber surface 3 of the table tennis racket 1, attached to the separator, stored, and reused.

  By the way, the conventional protective film 3 is used by adhering the adhesive layer formed on one surface thereof to the rubber surface 2 as described above, and the adhesiveness is gradually lost with repeated use. can not deny. In addition, a part of the adhesive layer (adhesive) may be peeled off from the base made of a synthetic resin sheet and attached to the rubber surface 2. In addition, the protective film 3 has a problem that it is easily torn from, for example, a fine scratched portion or a bent portion generated at the end portion thereof. Incidentally, the protective film 3 is generally used by cutting according to the shape of the rubber surface 2 as described above so that the protective film 3 is not unintentionally peeled off from the rubber surface 2. For this reason, when the end portion of the protective film 3 is rolled up and peeled off from the rubber surface 2 with a toe or the like, the raised end portion may be bent and the end portion may be finely scratched. Such bending or scratches cause damage to the protective film 3.

  The present invention has been made in consideration of such circumstances, and its purpose is to protect the rubber surface (object to be protected) of a table tennis racket from dirt, which is easy to handle and can be used repeatedly over a long period of time. It is in providing a suitable protective film.

In order to achieve the above-mentioned object, the protective film according to the present invention is affixed to a protection object and protects the surface of the protection object,
A foam adsorbing sheet having a sucker layer formed on one surface, and a sheet-like surface material adhered to a surface opposite to the surface on which the sucker layer of the foam adsorbing sheet is formed,
The surface material is characterized by being made of cloth fabric or leather lined with an olefin material.

  In addition, the foamed adsorption sheet having a suction layer formed on one surface is, for example, on one surface of a substrate such as paper or a synthetic resin sheet as disclosed in Japanese Patent Application Laid-Open No. 2006-176893 or Japanese Patent Application Laid-Open No. 1-259043. When a foam (sucker layer) formed with a large number of minute holes, so-called micro-suction cups (also called cell suction cups) is provided, and when adhered to the surface of the object to be protected (adhered body), It consists of what adheres to the surface of the said protection target object (adhered body) by the adsorption | suction effect | action by the said suction cup layer (micro suction cup / cell suction cup).

The cloth fabric refers to a woven fabric or knitted fabric that has been processed into a thin and wide shape by weaving or knitting thread-like natural fibers, regenerated fibers, or synthetic fibers, and also felt or nonwoven fabric. Such a cloth material or leather material lined with an olefin material is used as the surface material in the present invention.
Preferably, the object to be protected is a rubber surface of a table tennis racket, and the foam adsorption sheet has a size covering the entire rubber surface of the table tennis racket.

  In addition, it is preferable that the protective film further includes a sheet-like separator that is adsorbed on the surface of the sucker layer of the foamed adsorption sheet so as to be peelable from the surface of the sucker layer. The separator is peeled off from the foamed adsorption sheet when the protective film is attached to the object to be protected, and the sucker of the foamed adsorbent sheet of the protective film peeled off from the object to be protected It is adsorbed on the surface of the layer and used to protect the suction cup layer.

  According to the protective film of the above configuration, since the protective film is attached to the surface of the object to be protected using the adsorption action of the adsorbing layer of the foamable adsorbing sheet, like a protective film using a conventional adhesive sheet, There is no problem that a part of the adhesive remains on the surface of the object to be protected, and there is no problem that the adhesive force gradually weakens. In other words, since the protective film according to the present invention uses a foamable adsorbing sheet, when the adsorbing force is reduced due to dirt, the adsorbing force is restored by cleaning the adsorbing layer. Therefore, it can be used repeatedly over a long period of time.

  Further, the protective film according to the present invention has a structure in which a surface material made of cloth fabric or leather lined with an olefin material is bonded to the surface opposite to the surface on which the suction layer of the foamable adsorption sheet is formed. The foamable adsorbent sheet can be made difficult to tear, and the foamable adsorbent sheet can be made difficult to break. In addition, the protective film itself can have a certain thickness and a so-called “koshi” bending strength, and it is also effective in “fraying” and “fluffing” from the edge of the surface material. Can be prevented. Accordingly, it is possible to facilitate the attachment to a protection object (for example, a rubber surface of a table tennis racket) and to facilitate the peeling from the protection object.

The figure which shows the external appearance and magnitude | size of the protective film which concerns on one Embodiment of this invention. The figure which shows schematic sectional structure of the protective film which concerns on one Embodiment of this invention. The figure which shows the racket for table tennis and the protective film affixed on the rubber surface.

Hereinafter, a protective film according to an embodiment of the present invention will be described with reference to the drawings, taking a protective film for protecting a rubber surface of a table tennis racket as an example.
FIG. 1 is a perspective view showing the appearance and size of a protective film according to this embodiment. This protective film 10 is larger than a rubber surface of a table tennis racket to be protected, for example, a size of 17.5 cm square. For example, it has a thickness of about 0.8 to 1.0 mm. In addition, a pattern, a logo mark, etc. are suitably printed on the surface of the protective film 10 in order to enhance the product appeal effect.

  Now, as shown in FIG. 2, the protective film 10 has a foam adsorbing sheet 13 having a sucker layer 12 formed on one surface of a sheet-like substrate 11 made of, for example, an acrylic resin, and the foam adsorbing film. And a sheet-like surface material 14 bonded to the surface of the sheet 13 opposite to the surface on which the suction cup layer 12 is formed. The surface material 14 is made of a cloth fabric (or leather) 16 lined with an olefin material 15, and the fabric material (or leather) 16 is used as the surface side of the foam adsorption sheet 13, specifically, the base material 11. The other side is bonded and integrated, for example, via an acrylic adhesive 17.

  In addition, it may replace with the adhesive agent 17 and you may adhere | attach the foam adsorption sheet 13 and the surface material 14 using a sheet-like, what is called double-sided adhesive tape. Further, a separator 18 made of, for example, a PE (polyethylene) sheet is detachably provided on the surface of the suction cup layer 12 (the back surface of the protective film 10) formed on one surface of the foam adsorption sheet 13. The separator 18 is affixed to the sucker layer 12 using the suction force of the sucker layer 12.

  Incidentally, the foam adsorbing sheet 13 having the suction layer 12 formed on one side is made of, for example, “Zeon AL sheet (trade name)” sold by Nippon Zeon Co., Ltd. It has a structure provided with a foam (sucker layer) 12 in which a large number of (cell suction cups) are formed. By the adsorption action of the suction cup layer (micro suction cup / cell suction cup) 12, an object to be protected (covered) It adheres to the surface of the body).

  In this embodiment, a cotton cloth is used as the cloth material 16 of the surface material 14, but other natural fibers, regenerated fibers, and further a woven fabric made of synthetic fibers in a cloth shape, or a felt or a non-woven fabric may be used. Also, it may be a leather material that has been thinned. Whichever material is used as the cloth dough 16, the cloth dough 16 is lined with an olefin material 15 to give a bending strength called “koshi”, and “fray” from the end portion. The surface material 14 that prevents “fluffing” is realized.

  The protective film 10 having such a layer structure is peeled off the separator 18 and attached to the rubber surface 2 of the table tennis racket 1 which is the object to be protected, and serves to prevent the rubber surface 2 from being stained. Incidentally, attachment of the protective film 10 to the rubber surface 2 of the table tennis racket 1 is performed as follows. First, the rubber surface 2 of the table tennis racket 1 is cleaned using a dedicated cleaner, and the dirt adhering to the surface is removed. Next, the separator 18 of the protective film 10 is peeled off to expose the sucker layer 12 of the foamed adsorption sheet 13, and the exposed sucker layer 12 is adhered to the rubber surface 2 of the table tennis racket 1 to protect the rubber surface 2. A film 10 is pasted.

  When the protective film 10 is attached to the rubber surface 2, for example, it is preferably performed from one end side of the rubber surface 2 while being gradually closely adhered so that air does not enter between the rubber surface 2 and the protective film 10. . Further, when the protective film 10 is used for the first time, the protective film 10 is larger than the rubber surface 2, and therefore, after the pasting is finished, a portion of the protective film 10 that protrudes from the rubber surface 2 using scissors or a cutter is used. It is desirable to remove and match the protective film 10 to the shape of the rubber surface 2. If the protective film 10 is cut in accordance with the shape of the rubber surface 2 in this way, the protective film 10 does not protrude from the edge of the rubber surface 2, so that the end is bent due to unintended external force, Alternatively, problems such as rising from the rubber surface 2 can be effectively prevented.

As described above, the table tennis racket 1 with the protective film 10 attached to the rubber surface 2 is stored in a racket case (not shown). At this time, it is desirable to store the separator 18 peeled from the protective film 10 together.
When the table tennis racket 1 is used, the protective film 10 affixed to the rubber surface 2 is lifted from the end and peeled off from the rubber surface 2. And the protective film 10 peeled from the rubber surface 2 is affixed and stored on the separator 18 peeled from the protective film 10 first, and is used again.

  At this time, if the adsorbing layer 12 of the protective film 10 peeled off from the rubber surface 2 is contaminated and its adsorbing power is reduced, the adhering layer 12 is removed by washing the protective film 10 (adsorbing layer 12) with water. Then, after sufficiently drying, it is attached to the separator 18 and stored as described above. Since the adsorption force of the adsorption layer 12 is restored simply by removing the dirt of the adsorption layer 12 by such washing with water, the protective film 10 can be used repeatedly over a long period of time.

  According to the protective sheet 10 according to the present invention described above, the adhesive force of the foamed adsorption sheet 13 is applied to the rubber surface 2 of the table tennis racket 1, so that the adhesive sheet is different from the conventional “adhesive rubber film”. Such a pressure-sensitive adhesive is not required, and a problem such as a part of the pressure-sensitive adhesive sticking to the rubber surface 2 does not occur. In addition to this, a layer structure in which the surface material 14 mainly composed of the cloth fabric 16 is bonded to the surface of the foam adsorption sheet 13 increases the overall thickness (volume) and improves the feeling of handling. Can be facilitated.

  Moreover, since the cloth material 16 lined with the olefin material 15 is used as the surface material 14, the surface material 14 can have a bending strength called “koshi”, and the end of the surface material 14 can be given. “Fraying” and “fluffing” from the part can be effectively prevented. As a result, the surface material 14, and thus the protective film 10, can be made difficult to tear and can be made difficult to break at the same time, so that the protective film 10 is effectively prevented from being damaged when the protective film 10 is peeled off from the separator 18 or the rubber surface 2. Can do. Therefore, effects such as the ability to stably and repeatedly use the protective film 10 over a long period of time under simple handling are exhibited.

  The present invention is not limited to the embodiment described above. Here, the protective film 10 that protects the rubber surface 2 of the table tennis racket 1 from dirt has been described as an example, but it can also be realized as a protective film for protecting the display surface of a portable notebook computer from dirt, for example. It is. In this case, it is also useful to use a synthetic resin transparent body as the surface material 14.

  It can also be realized as a protective film for optical recording media such as CD and DVD. In this case, it is also useful to realize a so-called storage case in which a plurality of protective films are overlapped and one end thereof is bound, and an optical recording medium (optical disk) is adsorbed to each protective film and stored. In such a storage case, the above-described surface material 14 also functions as a cushion material positioned between a plurality of optical recording media, and thus has a great advantage. In addition, the present invention can be variously modified and implemented without departing from the scope of the invention.
