Description

Technical Field

[0001] The present invention relates to a sheet attachment set for attaching a protective sheet to a display screen for in-vehicle use and a frame portion surrounding the periphery thereof, and an attachment method for attaching the protective sheet of the sheet attachment set to the display screen and the frame portion surrounding the periphery thereof.

Background Art

[0002] Devices such as a car navigation system having a so-called display screen are mounted on automobiles. When this display screen is equipped with a touch panel, a protective sheet may be attached to prevent the screen from getting dirty or damaged.

[0003] As such a protective sheet to be attached to a display screen, Japanese Patent Application Laid-Open No. 2006-145918 discloses "a protective sheet mounting structure for mounting a protective sheet to be attached to a surface to be protected of an electronic device, wherein the protective sheet has a planar shape covering the surface of the surface to be protected, and is configured by forming an adhesive layer on one surface thereof, and a release sheet that is bonded to the surface of the protective sheet on which the adhesive layer is formed and is peeled off when the protective sheet is attached to the surface to be protected, and has a planar shape larger than the planar shape of the protective sheet, and an alignment portion formed in a shape that can be aligned along at least one side of the surface to be protected, and a handle portion formed to protrude from a side different from the alignment portion."

[0004] However, in recent years, due to the increase in the amount of information and the operation of in-vehicle devices such as air conditioners, the display screen has been enlarged. For example, conventionally, a display screen with a size of 7 inches has now exceeded 11 inches. When the above protective sheet is attached to such a relatively large display screen, problems such as wrinkles forming or dust intrusion not being preventable may occur.

[0005] In addition, the frame portion called the bezel surrounding the display screen may be decorated with so-called piano black, and there is also a demand to prevent dirt or damage to this portion.

[0006] Therefore, not only the display screen but also the frame portion called the bezel surrounding the display screen must be protected from dirt or damage. However, when attaching a protective sheet with such a relatively large area, problems may occur such as further wrinkling or inability to prevent dust intrusion.

Problems to be Solved by the Invention

[0008] The present invention has been made in view of the above points, and the problem is to accurately provide a sheet attachment set for attaching a protective sheet to a display screen, not only for a relatively large display screen but also for the frame portion surrounding the display screen, and a method for attaching the same.

Means for Solving the Problems

[0009] In order to solve the above problems, the protective sheet attachment set according to the first aspect includes a protective sheet having an upper end portion for attaching to a display screen and a frame portion surrounding the periphery thereof, a pair of guide seals attached with a predetermined interval to the upper end portion, and a seal attached between the pair of guide seals attached at a predetermined interval.

[0010] In order to solve the above problems, the protective sheet attachment set according to the first aspect includes a protective sheet having an upper end portion for attaching to a display screen and a frame portion surrounding the periphery thereof, and attached with a predetermined interval to the upper end portionA pair of two instruction seals and a seal attached at a predetermined interval A pair of two instruction seals and has a seal to be attached between them.

[0011] Also, in the second aspect, the protective sheet attachment set of the third aspect is such that the protective sheet has a concave portion for avoiding operation buttons on the display screen.

[0012] Further, in the third aspect, the protective sheet attachment set of the fourth aspect has a handle portion inserted between the protective sheet and the frame portion surrounding the display screen and its periphery, and a dust collecting sheet for attaching dust that has entered between them, in order to remove the dust that has entered between the protective sheet and the frame portion surrounding the display screen and its periphery when the protective sheet is attached to the frame portion surrounding the display screen and its periphery.

[0013] Also, the method of attaching a protective sheet to the display screen of the fifth aspect and the frame portion surrounding the periphery thereof is to use the protective sheet attaching set of the fourth aspect to attach the protective sheet to the frame portion surrounding the display screen and its periphery. The protective sheet with the release sheet attached is applied to the display screen, with the upper end aligned with the upper end of the display screen, and a pair of two indicating seals are attached to the upper end at a predetermined interval in the indicating seal attaching step. In the upper end seal attaching step, a seal is attached between the pair of two indicating seals attached to the upper end at a predetermined interval. In the state where a seal is attached between the pair of two indicating seals, the protective sheet with the release sheet attached is rolled up, the release sheet is peeled off from the protective sheet, and the protective sheet is attached to the frame portion surrounding the display screen and its periphery in the protective sheet attaching step. When dust enters between the protective sheet, the display screen, and the frame portion surrounding the periphery thereof, a handle portion is inserted between the protective sheet, the display screen, and the frame portion surrounding the periphery thereof, and the removed indicating seal is attached so as to overlap the handle portion. The protective sheet is peeled off up to the location where dust has entered to expose the dust in the dust exposure step. In the dust removal step, a dust removal sheet is brought into contact with the exposed dust, and the dust is removed by attaching the exposed dust to the dust removal sheet.

Advantages of the Invention

[0014] Since the present invention is configured and operates as described above, it is possible to provide a sheet attaching set for accurately attaching a protective sheet to a display screen, and a method of attaching the same, not only for a relatively large display screen but also for the frame portion surrounding the display screen.

Best Mode for Carrying Out the Invention

[0016] Hereinafter, this example will be described with reference to the illustrated embodiments. The sheet sticking set 10 for sticking the protective sheet 20 to the display screen 300 of this example and the frame part 400 surrounding the circumference thereof includes the protective sheet 20, a pair of two indication seals 60, 60, and a seal 70 to be stuck between the pair of two indication seals 60, 60. Further, it has a peeling sheet 80 detachably attached to the protective sheet 20, and also has a dust collection sheet 90. Furthermore, it may have a handle part 80a.

[0017] The protective sheet 20 has an adhesive layer on its back surface, and is preferably a film-shaped synthetic resin sheet. Further, the protective sheet 20 has an area sufficient to be attached to the in-vehicle display screen 300 and the frame portion 400 surrounding the periphery thereof, and has an upper end portion 21 that is substantially linear and is attached to the frame upper end portion 310 of the frame portion 400 including the upper end portion 210 of the main body of the display screen 300, a right side portion 22 that is attached to the frame right side portion 320 of the frame portion 400 including the right side portion 220 of the main body of the display screen 300, a left side portion 23 that is attached to the frame left side portion 330 of the frame portion 400 including the left side portion 230 of the main body of the display screen 300, and a lower end portion 24 that is attached to the frame lower end portion 440 of the frame portion 400 including the lower end portion 240 of the main body of the display screen 300.

[0018] The right side portion 22 has a semi-elliptical concave portion 221 and a semi-elliptical concave portion 222 that avoid the operation buttons of in-vehicle air conditioners and audio, and an angular concave portion 223. Further, the left side portion 23 has a semi-elliptical concave portion 231 that avoids the buttons for operating the in-vehicle navigation system and in-vehicle accessory devices, and an angular concave portion 232.

[0019] A pair of two indicating seals 60, 60 can use a tack paper having an adhesive layer on its back surface and is in a strip shape. Further, for the seal 70, it is preferable to use a roll-shaped masking tape having an adhesive layer on its back surface.

[0020] Further, the release sheet 80 is preferably a film-shaped synthetic resin sheet. Further, the release sheet 80 is substantially the same shape as the protective sheet 20, and has a release sheet upper end portion 81 that is substantially linear and is attached to the frame upper end portion 310 of the frame portion 400 including the upper end portion 210 of the main body of the display screen 300, a release sheet right side portion 82 that is attached to the frame right side portion 320 of the frame portion 400 including the right side portion 220 of the main body of the display screen 300, a release sheet left side portion 83 that is attached to the frame left side portion 330 of the frame portion 400 including the left side portion 230 of the main body of the display screen 300, and a release sheet lower end portion 84 that is attached to the frame lower end portion 440 of the frame portion 400 including the lower end portion 240 of the main body of the display screen 300.

[0021] Note that the right side portion 82 of the release sheet has a right protrusion 82a that protrudes further in the right direction R than the right side portion 82 of the release sheet at a position slightly lower in the downward D direction from the upper end portion 81 of the release sheet, and a right protrusion 82b that protrudes in the right direction R from the right side portion 82 of the release sheet. Similarly, the left side portion 83 of the release sheet has a left protrusion 83a that protrudes further in the left direction L than the left side portion 83 of the release sheet at a position slightly lower in the downward D direction from the upper end portion 81 of the release sheet.

[0022] In addition, the right side portion 82 of the release sheet 80 in the release sheet has a semi-elliptical concave portion 221 and a semi-elliptical concave portion 222 that avoid the operation buttons 360, 370, and 380 for in-vehicle air conditioners and audio, a rectangular concave portion 223, and release concave portions 821, 822, and 823 that match the shape thereof. Also, the left side portion 83 of the release sheet 80 in the release sheet has a concave portion 231 and a concave portion 232 that avoid the operation buttons 390 and 400 for operating the in-vehicle navigation system and in-vehicle accessory devices, and release concave portions 831 and 832 that match the shape thereof.

[0023] In this way, the release sheet 80 having substantially the same shape as the protective sheet 20 has the above-described right protrusions 82a, 83b and left protrusion 83a protruding from the protective sheet 20. In this way, the release sheet 80 is larger than the area of the protective sheet 20, and the release sheet 80 is in a state of protruding from the protective sheet 20. Therefore, it is easier to peel off the release sheet 80 attached to the protective sheet 20 by a user (not shown) gripping the right protrusions 82a, 82b and left protrusion 83a.

[0024] The dust collection sheet 80 preferably has a tack paper with an adhesive layer on its back surface, and can literally adhere dust and other debris.

[0025] The handle portion 80a functions as a handle for a user (not shown) to grip, and is preferably a film-like synthetic resin sheet. Further, a part of the release sheet 80 which is a film-like synthetic resin sheet can be cut out to create the handle portion 80a.

[0026] Next, a pasting method for pasting the protective sheet 20 onto the display screen 300 and the frame portion 400 surrounding the same using the above sheet pasting set 10 will be described.

[0027] Apply the protective sheet 20 with the release sheet 80 attached thereto onto the display screen 300, align the upper end portion 21 with the upper end portion of the display screen 300, and in this state, attach a pair of two indicating seals 60, 60 at a predetermined interval to the upper end portion 21 (indicating seal attaching step).

[0028] Next, in the above indicating seal attaching step, attach a seal 70 between a pair of two indicating seals 60, 60 attached to the upper end portion 21 at a predetermined interval (upper end portion seal attaching step).

[0029] In the above upper end portion seal attaching step, when the protective sheet 20 with the release sheet 80 attached thereto is fixed to the display screen 300, roll up the protective sheet 20 with the release sheet 80 attached thereto, peel off the release sheet 80 from the protective sheet 20, and attach the protective sheet 20 to the display screen 300 and the frame portion 400 surrounding the same (protective sheet attaching step). At this time, attach the protective sheet 20 while pressing it with a spatula (not shown) so that no air enters between the protective sheet 20, the display screen 300, and the frame portion 400, and remove the pair of two indicating seals 60, 60 and the seal 70. Note that since the above right protruding portions 82a, 83b and the left protruding portion 83a protrude at a position slightly downward in the D direction from the upper end portion 81 of the release sheet, they are easy to hold and it is easy to peel off the release sheet 80 from the protective sheet 20.

[0030] At this time, during the protective sheet attachment process, dust G may enter between the protective sheet 20, the display screen 300, and the frame portion 400. In this case, if the dust G is not removed, the display screen 300 and the frame portion 400 to be protected may be scratched or the appearance may be damaged. Therefore, the handle portion 80a is inserted between the protective sheet 20 and the frame portion 400. Note that it is preferable to insert the handle portion 80a between the corner portion where the upper end portion 21 and the right side portion 22 of the protective sheet 20 intersect, and the frame portion 400. Also, the removed instruction seal 60 is attached so as to overlap the handle portion 80a from above. Note that when the handle portion 80a is inserted between the corner portion where the upper end portion 21 and the right side portion 22 of the protective sheet 20 intersect, and the frame portion 400, the instruction seal 60 is attached so as to overlap the handle portion 80a from above the corner portion where the upper end portion 21 and the right side portion 22 of the protective sheet 20 intersect. In this case, the handle portion 80a and the instruction seal 60 are attached with the protective sheet 20 sandwiched therebetween. In this state, a user (not shown) holds the handle portion 80a and the instruction seal 60, peels off the protective sheet 20 to the location where the dust G has entered, and exposes the dust G (dust exposure step). At this time, since the user (not shown) holds the handle portion 80a and the instruction seal 60, fingerprints do not adhere to the protective sheet 20.

[0031] The dust removal sheet 80 is wound around the finger of a user (not shown) and brought into contact with the exposed dust G, and the exposed dust G is removed by adhering it to the dust removal sheet 80 (dust removal step). In this way, the dust G adhering to the protective sheet 20, the display screen 300, or the frame portion 400 can be removed by the dust removal sheet 80.

[0032] Thereafter, the user (not shown) holds the handle portion 80a and the instruction seal 60, reattaches the peeled-off protective sheet 20 to the display screen 300, and removes the handle portion 80a and the instruction seal 60, thereby completing the attachment of the protective sheet 20.

[0033] Thus, in each of the above steps, that is, in order to attach the protective sheet to the display screen 300 and the frame portion 400 surrounding the display screen 300 using the protective sheet attachment set 10, the protective sheet 20 with the release sheet 80 attached is applied to the display screen 300, the upper end portion 21 is aligned with the upper end portion 310 of the display screen 300, and a pair of two indicating seals 60, 60 are attached to the upper end portion 21 at a predetermined interval, which is the indicating seal attachment step; an upper end seal attachment step of attaching a seal between the pair of two indicating seals 60, 60 attached to the upper end portion 21 at a predetermined interval; a protective sheet attachment step of rolling up the protective sheet 20 with the release sheet 80 attached while a seal is attached between the indicating seals 60, 60, peeling off the protective sheet 20 with the release sheet 80 attached, and attaching the protective sheet 20 to the display screen 300 and the frame portion 400 surrounding the display screen 300; when dust G enters between the protective sheet 20, the display screen 300, and the frame portion 400 surrounding the display screen 300, inserting the handle portion 81a between the protective sheet 20, the display screen 300, and the frame portion 400 surrounding the display screen 300, attaching the removed indicating seal 60 so as to overlap the handle portion 81a, peeling off the protective sheet 20 up to the location where the dust G has entered to expose the dust G, which is the dust exposure step; and a dust removal step of bringing the dust removal sheet 90 into contact with the exposed dust G and attaching the exposed dust G to the dust removal sheet 90 to remove the dust G. By sequentially executing these steps, it is possible to attach the protective sheet 20 to the relatively large-area display screen 300 and its frame portion 400 easily even for a beginner while removing the dust G.
