Description

  The present invention is a protective film for avoiding the damage and failure of a word processor or a personal computer (hereinafter simply referred to as a personal computer) keyboard due to scattering of dust, drinks, etc. The present invention relates to a keyboard protective film that can easily cover the keyboard simply by sticking it to a suitable position of the keyboard if the protective film to be cut is cut out.

  A conventional keyboard protective film is formed by forming an uneven surface on a plastic sheet so as to match a key layout for each model of a personal computer or the like, and is sold under a name such as a keyboard dustproof cover. This is a model in which a different unique key shape and key arrangement for each model of a personal computer is molded into a plastic sheet (hereinafter referred to as a sheet), and when the sheet is put on a keyboard such as a personal computer, the concave portion of the sheet And the convex portions of the keyboard are aligned with each other and are completely fitted. Therefore, when the model of the personal computer or the keyboard or the shape of the keyboard is different, the uneven surface of the keyboard and the keyboard do not match, so the keyboard dust cover has a drawback that it is extremely difficult to divert to other models. there were.

  However, even after a model change of a personal computer or the like, for a customer who wants a seat of the target model, a large number of such sheets are stocked in the distribution market for a long time, and the manufacturer needs to preserve the mold for a long time. was there. Furthermore, in schools and offices that use various types of personal computers and the like, having a large number of spare seats for each model has resulted in significant waste of money and resources.

  As a technique for eliminating these defects, the applicant of the present application has proposed a protective film that can be attached to any keyboard by providing an adhesive tool on the keyboard frame in Japanese Patent Laid-Open No. 2003-208830. In consideration of the point that a part of the protective film of Japanese Patent Application Laid-Open No. 2003-208830 is adhered to the keyboard frame, the protective film has a two-layer structure of the front and back surfaces, or a keyboard for which the entire back surface is given adhesiveness. A protective film is commercially available.

  However, such a two-layer structure or a protective film imparted with tackiness has the following problems when actually used. The first point is that since the entire surface is an adhesive layer, all surfaces are sticky when pasting this protective film, so that the parts that come into contact with the keyboard are easy to stick together and parallel to the vertical length of the keyboard. In addition, it was very difficult and difficult to handle. Furthermore, the second point is that the entire surface is an adhesive layer, so the adhesive part of the keyboard frame, for example, is adhered without a gap, and the heat of the PC body loses its escape, so the protective film is clouded by heat. It sometimes happened.

  Therefore, in the present application, only the two sides of the upper side, the lower side, the left side, and the right side of the substantially rectangular film body, the upper side being the left side or the right side, or the lower side being the left side or the right side are spaced apart at a fixed interval. A protective film was considered. If the two sides forming such a right angle were fixed, the entire protective film could be fixed, and the other two sides played a role in promoting air permeability, and heat did not accumulate. In addition, since only two sides are fixed, if this protective film is attached to the mount, and the board is drawn in various rectangles of various sizes, using the intersection of the two sides as a base point, It was possible to cut out and match various types of personal computers and keyboards.

  In addition to such a structure, the above-described problem is solved by using a resin material having a water-repellent and breathable material for the protective film itself.

  If the protective film of the present invention is used, it is fixed at two sides, and only the portion that contacts the keyboard frame is adhered, so that the protective film can be easily attached.

  In addition, since the fixed part is two sides and the other side is free, there is a suitable gap between the protective film and the keyboard frame, and the protective film becomes cloudy because it has good air permeability and does not accumulate heat. Very easy to use.

  According to the keyboard protective film of the present invention, the damaged protective film can be easily peeled off from the keyboard frame. Therefore, if the film of the present invention is used, it can be simply attached to the keyboard frame at an appropriate position. Re-covering is possible. In addition, the film body is affixed to various keyboards, keyboard frame shapes, and mounts depicting standard shapes by manufacturer so that it can be adapted to various keyboards. Can be cut out easily. Accordingly, there is no need to stock various types of keyboard covers for each model as in the prior art, and no maintenance management is required for this, and a great saving can be achieved both economically and in resources.

  The basic structure of the keyboard protective film of the present invention is that a film body that protects a keyboard of a personal computer has an adhesive material attached to an end of the film body, and the adhesive material is used to position the keyboard frame at a suitable position. The film body can be detachably attached.

  The film body is affixed to a mount on which various types of keyboards and keyboard frame shapes, or standard shapes by manufacturer are drawn, corresponding to the target model and keyboard size, etc., and fits the target model The film body to be cut was easily cut out from the top of the mount with a scissors or the like.

  Furthermore, the film body has no adhesiveness to keys and keyboards, can be touched smoothly without impairing the heat dissipation of the PC, is made of a material that does not adsorb dust due to static electricity, and has an appropriate thickness. A plastic film that can be easily cut out is suitable.

  EXAMPLES Hereinafter, although this invention is demonstrated based on an Example, unless it deviates from the summary of invention, it is not limited to these examples. In other words, FIG. 1 is an image of a keyboard of a general desktop personal computer, and shows a partial perspective view of a keyboard and a film body as an example of an embodiment of a universal keyboard protective film according to the present invention. A large number of keys 10 are arranged on the keyboard to form a keyboard frame 8. The film body 6 is cut out in accordance with the shape of the keyboard frame body 8, the adhesive material 2 is attached to the right end portion, and a pasting expected portion 4 corresponding to this is secured. There is an adhesive material 1 in a direction perpendicular to the adhesive material 2, and a pasting prospective portion 5 corresponding thereto. The film body 6 is in a standby state before being attached so as to cover the keyboard frame 8.

  2 and 3 show an example of an embodiment of a keyboard protective film according to the present invention, and are partially enlarged views as seen from the front of the keyboard, respectively. In FIG. 2, the adhesive material 2 is attached to the end of the film body 6, and the adhesive surface 3 of the adhesive material 2 faces the keyboard 8 and is in a standby state before being attached to the keyboard frame body 8. Since release paper is attached to the adhesive surface 3, there is no problem with no adhesiveness to others during handling. If the release paper is peeled off, it can be easily attached to the keyboard frame 8. Here, the film body 6 is attached to the keyboard frame 8 in a standby state, and shows a key 10 and a key hitting surface 10a before a stroke. The film body 6 is parallel to the key hitting surface of each key and is in a standby state. I understand that there is.

  In FIG. 3, the key adjacent to the key 10 is shown as the key hitting surface 10b after the stroke. Here, it can be seen that the film body 6 at the place where it is driven is lowered to the position of the key hitting surface 10b. Even when the film body 6 sinks to the height of the key striking surface 10b when the key is driven, the film body 6 is tensioned because it is fixed by the adhesive material 2. Therefore, the height (thickness) of the adhesive material 2 is preferably intermediate between the height of the key 10a and the height of the key surface 10b. The design of the height (thickness) of the adhesive material 2 is preferably set between the key 10a and the key 10b. Further, the film body 6 is preferably a plastic film having an appropriate elasticity so as to function with a minimum tension.

  In general, a keyboard for a desktop computer has a large keystroke. In a notebook computer, the keyboard hitting surface is generally as high as the surface of the keyboard frame 8 because it has a liquid crystal screen as a lid. The keystrokes are small. Therefore, the level difference between the key 10 and the keyboard frame 8 is small, and the gap through which air moves is small. Therefore, the stick-shaped adhesive material 2 having a certain thickness is suitable for the desktop keyboard frame 8, but the notebook-type keyboard frame 8 is thin and has a tape-shaped adhesive material. 2 is preferred. Furthermore, when the key height is large, such as a keyboard for a desktop personal computer, there is a large gap between the film body 6 and the keyboard frame body 8, so every time the key is driven, The film body 6 sinks into the position of the key hitting surface 10b and crawls the film body 6, so that the movement of air is promoted and a certain degree of heat dissipation can be expected.

  FIG. 4 is an image diagram showing a keyboard of a notebook computer, and shows a plan view of the notebook computer as an example of an embodiment of a keyboard protective film according to the present invention. Here, the film body 16 is cut out in an intricate shape so as not to cover the touch pad 12 in accordance with the shape of the keyboard frame body 18 and is in a standby state before being attached. The keyboard frame 18 shows a prospective attachment portion 14 of the adhesive material 22 surrounded by a two-dot chain line at a relative position of the adhesive material 22. The number of attachments of the adhesive material 22 may be considered depending on the size of the keyboard frame 18 and the like.

  It can be seen that an adhesive material 22 is attached to the end portion of the film body 16, and each pasting expected portion 14 is secured at a position opposite to the keyboard frame 18. The main adhesive material 22 is preferably provided at a position where the enter key of the personal computer is located, that is, usually near the right end of the keyboard frame 18. That is, the enter key is generally the most frequently driven and the film body 16 is easy to move each time the key is touched. Therefore, the position where the film body 16 is fixed is preferably close. .

  As described above, in the notebook computer, when the film body 16 adheres to the keyboard frame 18 or the key 20 or the like, there is no escape space for the heat generated by the personal computer body, the heat radiation range is obstructed, and the operation time of the ventilation fan is reduced. Will increase. This is a fatal defect that significantly accelerates battery drain and must be avoided as much as possible. The proposed protective film is designed so that all of these problems can be cleared.

  FIG. 5 shows the attachment positions of the cutting line 24 and the adhesive material 22 drawn on the mount as viewed through the free-size film body 16 attached to the mount. Since the cutting line 24 depicts various keyboard patterns and the like, it shows that a shape suitable for the target keyboard 18 can be cut out using a scissors or the like in the manner of taking a pattern. And since the adhesive material 22 is attached to the edge part of the cut-out film body 16, the release paper is removed from the adhesive surface 3 of the adhesive material 22, and only attached to a suitable position of the keyboard frame 18. Thus, simple re-covering is possible.

  The film body 16 may be made of a plastic material having appropriate flexibility and transparency and no self-adhesiveness. For example, if a film body made of a material such as nylon or ethylene vinyl acetate is attached to a base paper that also serves as a pattern paper, for example, in the form of a masking film, it is very convenient when cutting into an arbitrary shape with a scissors or the like. That is, it is preferable that the mount is provided with weak adhesiveness, and the film body 16 is attached thereto as a protective film.

  For the mount that also serves as the above-mentioned pattern, for example, several types of keyboard shapes for each manufacturer can be printed with multiple lines, for example, with different colors. It can correspond to. Further, if the film body as described above is subjected to a surface treatment or the like for preventing static electricity or reducing reflection of light, the usability is further improved.

  In addition, as the adhesive material 22, a material that is generally not too strong is suitable. For example, a material having a soft adhesive property such as a latex system or a gelling agent-added system is re-stretched or repeatedly pasted. Suitable for use.

  As described above in detail, according to the present invention, a protective film suitable for a target keyboard can be cut out from a flat film body of a free size regardless of the model or shape of a personal computer or the like. It is possible to easily cover the keyboard. There is no need for a wide variety of stocks and manufacturing as in the past, and it is effective for resource conservation while achieving both economic cost and maintainability.
