  Since the thing of patent documents 1-3 is a thin sheet | seat shape as a whole, as mentioned above, you have to use it by pressing against a display with a fingertip. However, when wiping work while pressing with a fingertip, if the area to be wiped is large, the work is difficult and takes time. For this reason, the wiping target illustrated in Patent Documents 1 to 3 is only about 3 inches even if the screen size is large, such as a display of a mobile phone or a portable game machine. Absent.

  In recent years, with the spread of liquid crystal televisions and the like, large screen displays exceeding 30 inches have become widespread, but even such large screen displays can even wipe off the displays of personal computers around 15 inches, even if not so far. However, the sheet-like material as described above is difficult to handle and takes time.

  The present invention has been made in view of the above, and an object of the present invention is to provide a wiping tool that is easy to perform wiping work and is suitable for wiping off dirt such as a display or a mirror surface having a relatively large screen size.

  In order to solve the above problems, a wiping tool of the present invention includes a cushion material, a sheet material laminated on the cushion material, and having a function of wiping off dirt of an article to be wiped, and the cushion material and the sheet material. A case member that functions as a grip when used, and a bonding layer provided on the case member to store the case member in an appropriate place when not in use. It is characterized by that.

  It is preferable that the sheet-like material is detachably stacked on the cushion material. In addition, the sheet-like object is provided so as to be relatively movable on the surface of the cushion material, and an operation unit is provided on the case member to move the sheet-like material relative to the cushion material. By operating the unit, it is possible to change the wiping surface of the sheet-like object in contact with the article that is the object to be wiped.

  The cushion material is formed in a roller shape and is rotatably supported by the case member, and the sheet-like material is arranged by being wound around the cushion material formed in the roller shape. The cushion material formed in the roller shape can be rotated to change the wiping surface of the sheet-like material.

  A laminated body composed of a combination of the cushion material and the sheet-like material is accommodated in the case member and connected to the case member, and contacts the article to be wiped by separating in order from the outermost one. It can also be set as the structure which changes the laminated body to be made.

  A plurality of the sheet-like materials are stacked on the cushion material, and the sheet-like materials to be brought into contact with the article to be wiped can be changed by sequentially separating the sheet-like materials. .

  The cushion material has at least one acute angle portion on the outer shape of the surface on which the sheet-like material is stacked, and the sheet-like material is provided so as to cover the corner portion of the acute angle portion. Is preferred. The wiper of the present invention is particularly suitable for a display having a screen size of 15 inches or more.

  According to the present invention, the sheet-like material having the wiping function is housed in the case member together with the cushion material. Since the case member functions as a grip portion, the user may hold the case member and move the sheet-like object back and forth and right and left in contact with the display or mirror to be wiped. Since it is not necessary to press the sheet-like material directly with fingers as in the prior art, the resistance is small, and the sheet can be moved back and forth and left and right with a small force, which contributes to the improvement in the workability of the wiping operation. Therefore, it is suitable for wiping work such as a 15-inch or larger display larger than a display screen of a mobile phone or a portable game machine, or a mirror having a size equivalent thereto.

  The sheet-like material is laminated on the cushion material. For this reason, the pressing force when the sheet-like material is pressed against a display or the like can be relaxed, which is suitable for a liquid crystal display or the like. And the wiping tool of this invention is integrally provided with joining layers, such as an adsorption sheet, in the case member. Therefore, when not in use, it can be attached to the display or the like that is the object to be wiped off, for example, on the side or back of the display, or the side of the display stand, etc. You can pick it up quickly.

FIG. 1 is a perspective view showing a wiping tool according to one embodiment of the present invention. FIG. 2 is an exploded perspective view of FIG. FIG. 3 is a view for explaining another aspect of the cushion material. FIG. 4 is a view for explaining another aspect of the wiping tool. FIG. 5 is a view for explaining still another aspect of the wiping tool. FIG. 6 is a view for explaining an aspect of a wiping tool using a cushion roller. FIG. 7 is a view for explaining still another aspect of the wiping tool.

  Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings. 1 and 2 show a wiping tool 1 according to one embodiment of the present invention. The wiping tool 1 includes a cushion material 10, a sheet-like material 20, a case member 30, and an adhesive layer 40.

  The cushion material 10 is not limited as long as it has elasticity that relieves the pressing force when pressed against an article such as a display, and the material thereof is not limited. For example, foamed polyurethane, woven or knitted fabric, nonwoven fabric, etc. What laminated | stacked two or more cloth materials which consist of can be used. Although the thickness is not limited, a thickness of about 5 to 50 mm is usually selected.

  The sheet-like material 20 can wipe off dirt and dust on the surface of the display or mirror, for example, a wiping made of woven or knitted fabric or nonwoven fabric made of ultrafine fibers of 1.1 decitex or less. A cloth can be used. Although thickness is not specifically limited, For example, a 50-1000 micrometers thing can be used.

  The sheet-like material 20 is used by being laminated on the cushion material 10 described above. The lamination method may be performed by simply wrapping the periphery of the cushion material 10 or may be laminated by bonding or the like only on the surface (opposing surface 11) facing the wiping target portion such as a display in the cushion material 10. . In the present embodiment, in the cushion material 10, a notch 12 a is formed from the surface (opposite surface 12) opposite to the opposing surface 11, and the sheet-like object 20 is applied to the opposing surface 11 side, and then both end edges are opposite. It is laminated by turning to the surface 12 side and sandwiching in the notch 12a. If it does in this way, since the sheet-like object 20 becomes detachable with respect to the cushioning material 10, when the sheet-like object 20 becomes dirty, it becomes possible to exchange and use for a new sheet-like object 20. .

  As shown in FIGS. 1 and 2, the case member 30 has a substantially rectangular shape in plan view, and is formed in a substantially concave cross section with a peripheral wall 32 having a predetermined height around the bottom wall portion 31. In the concave portion 33 surrounded by the peripheral wall 32, the above-described cushion material 10 laminated with the sheet-like material 20 is disposed. In the present embodiment, the opposite surface 12 side of the cushion material 10 is housed in the recess 33. Since the edge 20a of the sheet-like material 20 is sandwiched in the notch 12a formed on the opposite surface 12 side, the portion that wraps around the opposite surface 12 side by placing in the recess 33 is the bottom of the case member 30. The sheet-like object 20 is fixed to the cushion material 10 by being sandwiched between the wall portions 31. The concave portion 33 stores the cushion material 10 and a part of the sheet-like material 20 in this way, but the concave portion 33 prevents the cushion material 10 and the sheet-like material 20 from dropping off in the stored state. 33 is formed in a smaller size in width and / or length than the cushion material 10.

  Since the cushion material 10 in which the sheet-like material 20 is laminated in the recess 33 of the case member 30 is disposed, the peripheral wall 32 having a predetermined height protrudes outward from the cushion material 10 and the sheet-like material 20 in a plan view. Will do. Therefore, the user can hold the case member 30 by hand, and the case member 30 functions as a gripping part during use. The shape of the case member 30 and the height of the peripheral wall 32 can be selected from various shapes and heights so that the case member 30 can be easily held by hand. For example, the shape of the case member 30 is substantially elliptical in a plan view, a part thereof is acutely shaped as shown in FIG. 3 to be described later, or the peripheral wall 32 is formed near the opposing surface 11 of the cushion material 10. The wiping surface 21 with the wiping target in the sheet-like object 20 may be exposed from the case member 30.

  A bonding layer 40 is provided on the back surface 31 a of the bottom wall portion 31 of the case member 30. The bonding layer 40 can be attached to a portion near the display or the like to be wiped off, for example, the side surface or the back surface of the display or the side surface of the display stand. And what is necessary is just to be able to adhere to a predetermined part again after use. As long as the bonding layer 40 has such a function, a known pressure-sensitive adhesive sheet or suction sheet can be used. For example, an acrylic polymer sheet having fine bubbles on the surface, specifically, a low-foamed foam having fine bubbles on the surface of 1.5 times, a thickness of about 0.5 mm, It is preferable to use a polymer sheet having a peeling peel strength of about 0.15 kg and a thickness of 500 μm to 800 μm because high adhesiveness can be obtained.

  According to this embodiment, when not in use, the bonding layer 40 is bonded to an arbitrary part, for example, the side surface of the liquid crystal television, and the wiper 1 is held. As described above, since the bonding layer 40 has adhesiveness and adsorbability that can be attached to or peeled from an arbitrary portion, a desired position that is easy for the user to take (for example, the side surface of the liquid crystal television). Can be bonded and held.

  In use, the case main body 30 that functions as a gripping part is grasped by hand, the bonding layer 40 is peeled off from the side surface of the liquid crystal television, and the wiping surface 21 of the sheet-like material 20 is liquid crystal while the case main body 30 is gripped. Touch the TV display and move it up and down or left and right to wipe off dust and finger grease. At this time, according to the present embodiment, the case main body 30 can be held and moved, so that it is possible to easily work without requiring a large force. Therefore, it is suitable for wiping work on a relatively large area wiping object such as a display of 15 inches or more or a mirror having a size corresponding to the display. Further, when wiping off, a slight force is applied in the pressing direction, but since the sheet-like material 20 is laminated on the cushion material 10, the force is relieved by the elasticity of the cushion material 10, thereby causing damage to the display. Is prevented.

  Note that the display (screen) of the liquid crystal television is provided in an outer peripheral frame, and there is usually a step at the boundary between the display and the frame. Therefore, when the display is wiped with the sheet-like object 20, dust or the like may accumulate near the step between the frame body. Therefore, as shown in FIG. 3, an acute angle portion 11 a is formed on at least a part of the outer shape of the cushion material 10 on the facing surface 11 side so that dust or the like that tends to collect near the step can be wiped off. Is preferred. Since the portion covering the acute angle portion 11a of the sheet-like material 20 also has an acute angle, dust or the like that reaches the middle of the step and tends to accumulate near the step can be easily wiped off.

  On the other hand, when it is used, dirt such as dust accumulates on the wiping surface 21 of the sheet-like material 20 and the wiping performance deteriorates. Therefore, a long sheet is prepared in advance as the sheet-like material 20 and wound around the cushion material 10, and the surplus portion is sandwiched in the cut 12a. And if dirt accumulates in the portion used as the wiping surface 21, the sheet-like object 20 is removed from the cushion material 10 and shifted, and the non-dirty surface is positioned on the opposing surface 11 of the cushion material 10, Make the surface a new wiping surface. Thereby, the sheet-like material 20 of 1 sheet can be used without waste.

  Further, instead of shifting only the sheet-like object 20, the unused surface of the sheet-like object 20 is displayed on the display by changing the surface stored in the recess 33 of the case member 30 for each cushion material 10. It can also be used as a new wiping surface for wiping.

  Further, as shown in FIG. 4, a plurality of laminated bodies 100 and 100 a obtained by laminating the cushion material 10 and the sheet-like object 20 are connected to each other, and the sheet of the laminated body 100 according to the first set located on the outermost side. If the product 20 becomes dirty, the first set of laminates 100 may be separated from the next set of laminates 100a to expose the sheet-like product 20 of the next set of laminates 100a. . Thereby, the unused sheet-like object 20 can be easily exposed one after another. In addition, it is preferable that the laminated bodies 100 and 100a can be easily separated, for example, by connecting only a part of the periphery.

  Moreover, as shown in FIG. 5, the cushion material 10 is made into one and it can also be set as the structure which laminated | stacked the several sheet-like object 20 on the opposing surface 11 so that peeling was possible mutually. In this case, if the outermost sheet-like material 20 becomes dirty, the sheet-like material 20 is separated and used so that the next sheet-like material 20 is exposed.

  FIG. 6 shows a case member 30 provided with a cushion material (cushion roller 50) formed in a roller shape. The case member 30 has an end wall surface opened, and a part of the cushion roller 50 is opened from the opening. (Front) is exposed. Further, a support roller 60 is disposed in the case body 30 at a predetermined interval with respect to the cushion roller 50, and an operation unit 61 that can rotate the support roller 60 is provided on a side surface of the case body 30. Then, the sheet-like object 20 is looped between the cushion roller 50 and the support roller 30.

  During normal use, the operation unit 61 is locked so that the support roller 60 does not rotate. In this state, the sheet-like material 20 is placed on the front surface of the cushion roller 50 exposed from the case member 30. The portion to be positioned (wiping surface 21) is pressed against the display for wiping. On the other hand, if the wiping surface 21 that has been used becomes dirty, the operation unit 61 is unlocked and the operation unit 61 is operated to rotate the support roller 60 and the cushion roller 50. The use surface is positioned in front of the cushion roller 50 and used as a new wiping surface. When such a cushion roller 50 is used, it is very easy to make the unused surface of the sheet-like material 20 a new wiping surface.

  FIG. 7 shows a wiping tool according to still another aspect. In this aspect, two support rollers 70 and 80 are arranged in a substantially rectangular parallelepiped case member 30 at a predetermined interval. The sheet-like material 20 is looped between the supporting rollers. The surface of the case member 30 (upper surface in FIG. 7) is an opening surface, and a part of the sheet-like material 20 that is looped from the opening surface is exposed, and that portion becomes the wiping surface 21. Yes. A cushion material 10 is disposed on the back side of the wiping surface 21.

  In the embodiment of FIG. 7, as in the embodiment of FIG. 6, during normal use, the operating portion 81 is locked so that the support roller 80 does not rotate. Of these, the wiping surface 21 exposed to the outside is pressed against the display for wiping. On the other hand, if the used wiping surface 21 becomes dirty, the operation unit 81 is unlocked and the operation unit 81 is operated to rotate the support rollers 70 and 80, and the unused surface of the sheet-like material 20. Is used as a new wiping surface. According to this aspect, it is possible to secure a wiping surface having a larger area than in the case of FIG.

  Although not shown in the drawings, in the modes shown in FIGS. 3 to 7, a bonding layer such as an adsorption sheet is provided on the outer surface of the case member 30 for holding when not in use. This is the same as the second embodiment.

  Further, the shapes of the cushion material 10 and the case member 30 described above are merely examples, and are not limited to those illustrated. Further, means for changing the wiping surface 21 of the sheet-like object 20 is not limited to the above-described aspect.

  Furthermore, in the above description, the case where it is mainly used for a display of a liquid crystal television is given as an example. However, the present invention is not limited to this, and it is used not only for a display for a personal computer but also for wiping work such as a mirror. It is also possible.
