[0003] [Patent Document 1] Utility Model Registration No. 3218775 Summary of the Invention [Problem to be solved by the invention]

[0004] Doors installed in closets and other areas of homes are covered with a resin film or other protective covering. The resin film is adhered to, for example, the bottom or top surface of the door, which is the end grain. After the door is installed in the home, the resin film is removed from the door. At this time, some of the resin film may remain on the end grain. In particular, there is a problem in that the resin film remaining on the bottom surface of the door is difficult for workers to remove because the gap between the bottom surface of the door and the floor is narrow. In addition, when removing the resin film with a blade such as a cutter, the resin film is cut by the blade, making it difficult to remove all of the resin film.

[0005] The present invention has been made in view of the above problems, and has an object to provide a film remover that can easily remove a resin film adhering to the underside of a door. [Means for solving the problem]

[0006] (1) A film remover according to the present invention comprises a plate having a main surface, and a protrusion protruding from the main surface of the plate and tapering to a tip.

[0007] The plate is inserted between the underside of the door and the floor, and when the plate is slid with the protrusion pressed against the underside of the door, the protrusion moves while biting into the resin film attached to the underside of the door, causing the resin film that the protrusion has bitten into to peel off from the underside of the door.

[0008] (2) The protrusion may be elastically deformable in the thickness direction of the plate body.

[0009] The force of the protrusion pressing against the underside of the door causes the protrusion to elastically deform, making it less likely for the protrusion to abut against the underside of the door. Also, even if the plate moves slightly away from the underside of the door when sliding, the protrusion will remain in contact with the underside of the door.

[0010] (3) The plate and the protrusion may be an integrally molded product made of synthetic resin, and the protrusion may be plate-shaped.

[0011] Since both the plate body and the projections are made of resin, manufacturing costs can be reduced.

[0012] (4) The film remover may further include a protrusion protruding from the plate body.

[0013] The protrusion serves as a handle, making it easy to slide the plate when it is inserted between the underside of the door and the floor.

[0014] (5) The tip of the convex portion may be located on the side from which the protrusion projects relative to the main surface of the plate body.

[0015] The tip of the convex portion is separated from the floor surface, making it easy to hold the tip of the convex portion.

[0016] (6) The convex portion may be spaced apart from the projection.

[0017] The protrusion abuts against the underside of the door while the protrusion is separated from the surface of the door, providing good operability.

[0018] (7) The protrusions may be plural and aligned in a first direction along the main surface.

[0019] By inserting the plate between the underside and the floor so that the first direction is the thickness direction of the door, one of the protrusions can easily bite into the resin film attached to the underside of the door.

[0020] (8) Some of the plurality of protrusions may protrude from the main surface toward the tip so as to have a component in one direction in a second direction intersecting the first direction and the thickness direction of the plate body, and other some of the plurality of protrusions may protrude from the main surface toward the tip so as to have a component in the other direction in the second direction.

[0021] Whenever the plate body is slid in either of the second directions, the tip of one of the projections bites into the resin film.

[0022] (9) The plurality of protrusions may be triangular and cut out from the plate body, and the protrusions may be aligned in the second direction, and adjacent protrusions in the second direction may have different positions in the first direction.

[0023] Since the through holes formed by cutting and raising the protrusions from the plate are relatively far apart, cracks and the like are unlikely to occur in the plate around the through holes.

[0024] (10) In the protrusions arranged in the first direction, of the two interior angles other than the tip of the protrusion located at at least one end, one interior angle located on the one end side may be larger than the other interior angle and may be less than a right angle.

[0025] Since the distance between the tips of the protrusions located at both ends in the first direction is close to the overall length of the protrusions lined up in the first direction, the protrusions also easily dig into the resin film located at the ends in the thickness direction of the door. [Effects of the Invention]

[0026] According to the present invention, the resin film adhering to the underside of the door can be easily removed. [Brief explanation of the drawings]

[0028] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. Note that the embodiment described below is merely an example of how the present invention is realized, and it goes without saying that the embodiment can be modified as appropriate without departing from the spirit and scope of the present invention.

[0029] Hereinafter, directions related to the film removal tool 1 will be referred to as an up-down direction 7, a front-rear direction 8, and a left-right direction 9. The front-rear direction 8 and the left-right direction 9 are all perpendicular to the up-down direction 7 and are mutually perpendicular. The up-down direction 7 is the thickness direction of the plate body 10 (see FIG. 4), and is the direction in which both main surfaces of the plate body 10 face. The front-rear direction 8 is a direction along the main surfaces of the plate body 10, and is a direction along the short side of the plate body 10, which has a rectangular outer shape in a plan view. The left-right direction 9 is a direction along the main surfaces of the plate body 10, and is a direction along the long side of the plate body 10, which has a rectangular outer shape in a plan view. The up-down direction 7 is an example of a second direction. The front-rear direction 8 is an example of a first direction.

[0030] [Configuration of Resin Film 200 and Door 100] First, a resin film 200 and a door 100 to be removed by the film removal tool 1 will be described. As shown in Fig. 1, the door 100 is, for example, a wooden board 10, and is attached to, for example, a closet or a room entrance in a house. One of the main surfaces of the door 100 is covered with a resin film 200 or the like for protection. The resin film 200 is heat-welded to the top and bottom surfaces 110 of the door 100.

[0031] 1 does not show knobs and other components of the door 100. Although the resin film 200 covers only half of the rear area of the lower surface 110 of the door 100 in FIG. 1, it may cover the entire upper and lower surfaces 110. The resin film 200 may cover both main surfaces, or may cover at least a portion of the upper and lower surfaces 110 along the edges in the front-to-rear direction 8. The resin film 200 may be attached to the upper and lower surfaces 110 with an adhesive instead of by thermal welding. When the door 100 shown in FIG. 1 is attached to a closet or the like, the rear main surface covered by the resin film 200 is attached so that it faces outward.

[0032] The door 100 is attached to an opening such as a closet while being covered with the resin film 200. The resin film 200 is removed from the door 100, for example, when the house is handed over. As shown in FIG. 2, the distance between the lower surface 110 of the door 100 and the floor surface F is narrow, for example, 1 cm or less. When the resin film 200 is removed from the door 100, a part of the resin film 200 (hereinafter referred to as "resin film 210") may remain attached to the lower surface 110. The film remover 1 is used to remove the resin film 210 remaining on the lower surface 110 of the door 100.

[0033] As shown in FIG. 1, the side along the left - right direction 9 on the lower surface 110 of the door 100 is referred to as the long side L3. The side along the front - rear direction 8 on the lower surface 110 of the door 100 is referred to as the short side L4. As shown in FIG. 6, the dimension along the up - down direction 7 of the gap between the lower surface 110 of the attached door 100 and the floor surface F is referred to as the dimension D1.

[0034] [Configuration of Film Remover 1] The film remover 1 is insertable between the lower surface 110 of the door 100 and the floor surface F, and by sliding along the lower surface 110 of the door 100, it scrapes out and removes the resin film 210. The film remover 1 is, for example, a molded product integrally formed of synthetic resin. Examples of the synthetic resin include acrylic, polyethylene terephthalate, or polypropylene. As shown in FIGS. 3 to 5, the film remover 1 includes a plate body 10, a protrusion 20, and a convex portion 30.

[0035] [Plate Body 10] The outer shape of the plate body 10 in plan view is rectangular. As shown in FIG. 3, the long side L1 of the plate body 10 extends along the left - right direction 9 (an example of the second direction). The left - right direction 9 is the direction in which the film remover 1 slides along the lower surface 110 of the door 100. The long side L1 of the plate body 10 is shorter than the long side L3 (see FIG. 1) on the lower surface 110 of the door 100 (L1 < L3). The length of the long side L1 of the plate body 10 is, for example, about 5 to 10 cm.

[0036] The short side L2 of the plate body 10 extends along the front-rear direction 8. The short side L2 of the plate body 10 is longer than the short side L4 (see FIG. 1) on the lower surface 110 of the door 100 (L2 > L4). The length of the short side L2 of the plate body 10 is, for example, about 2 to 3 cm. The thickness of the plate body 10 is smaller than the dimension D1 between the lower surface 110 of the attached door 100 and the floor surface F (D1 < R1, see FIG. 6).

[0037] [Protrusion 20] The protrusion 20 protrudes from the upper surface 11 of the plate body 10. The upper surface 11 is one of the main surfaces of the plate body 10. The protrusion 20 has a mountain-shaped outer shape. The protrusion 20 tapers toward the tip 21 extending from the upper surface 11. A plurality of protrusions 20 are located on the upper surface 11 of the plate body 10. The plurality of protrusions 20 are arranged in the front-rear direction 8 and the left-right direction 9 on the upper surface 11 of the plate body 10. Among the protrusions 20 arranged in the front-rear direction 8, the protrusions 20a to 20d located on the front side of the upper surface 11 are separated from the front end 10F of the plate body 10 in the front-rear direction 8. Among the protrusions 20 arranged in the front-rear direction 8, the protrusions 20e to 20h located on the rear side of the upper surface 11 are separated from the rear end 10R of the plate body 10 in the front-rear direction 8.

[0038] Among the protrusions 20 arranged in the left-right direction 9, adjacent protrusions 20 have different positions in the front-rear direction 8. As a result, the tips 21 of adjacent protrusions 20 are at different positions in the front-rear direction 8. Among the protrusions 20 arranged in the left-right direction 9, the positions of the protrusions 20 located in the right region 11a on the upper surface 11 of the plate body 10 and the positions of the protrusions 20 located in the left region 11b on the upper surface 11 of the plate body 10 are line-symmetric in a plan view with respect to the symmetry axis P extending in the front-rear direction 8 along the upper surface 11 of the plate body 10.

[0039] The protrusions 20 form four rows in the left-right direction 9. In the first row and the fourth row, three protrusions 20 are located in the front-rear direction 8. In the second row and the third row, two protrusions 20 are located in the front-rear direction 8. The tips 21 of the two protrusions 20 located in the second row and the third row are each located between the tips 21 of the three protrusions 20 located in the first row and the fourth row in the front-rear direction 8.

[0040] Each of the protrusions 20 is a triangular plate shape cut and raised from the plate body 10. Among the upper surface 11 of the plate body 10, the protrusion 20 located in the right region 11a protrudes from the upper surface 11 of the plate body 10 toward the tip 21 so as to have a component directed to the right. Among the upper surface 11 of the plate body 10, the protrusion 20 located in the left region 11b protrudes from the upper surface 11 of the plate body 10 toward the tip 21 so as to have a component directed to the left. When each of the protrusions 20 is cut and raised from the plate body 10, a through hole 24 (see FIG. 5) that penetrates in the vertical direction 7 with the same shape as the shape of the protrusion 20 is located in the plate body 10.

[0041] Each of the protrusions 20 is elastically deformable in the vertical direction 7. The elasticity of the protrusion 20 may be, for example, such that it can be bent by the force of a human pressing the plate body 10 against the lower surface 110 of the door 100. The sum of the height H1 along the vertical direction 7 from the upper surface 11 of the plate body 10 to the tip 21 of the protrusion 20 and the thickness R1 of the plate body 10 is smaller than the dimension D1 (see FIG. 6) between the lower surface 110 of the door 100 and the floor surface F (H1 + R1 < D1). Thereby, with the protrusions 20 standing up from the plate body 10, the film remover 1 is inserted between the lower surface 110 of the door 100 and the floor surface F.

[0042] Among the protrusions 20 arranged in the front-rear direction 8, the protrusions 20a to 20d located on the most front end side are in a right triangle shape with the side along the upper surface 11 of the plate body 10 as the opposite side 22 and the side located on the front end side as the adjacent side 23. Among the protrusions 20 arranged in the front-rear direction 8, the protrusion 20 located on the most rear end side is in a right triangle shape with the side along the upper surface 11 of the plate body 10 as the opposite side 22 and the side located on the rear end side as the adjacent side 23. That is, in the front-rear direction 8, the length L5 between the tips 21 of the protrusions 20a and 20e located at both ends is equal to the total length L6 of the protrusions 20a to 20e arranged in the front-rear direction 8 on the upper surface 11 of the plate body 10.

[0043] [Convex portion 30] 3 to 5, the protrusion 30 protrudes from the rear end of the plate body 10. As shown in FIG. 4, the cross-sectional shape of the protrusion 30 is an L-shaped plate extending in the up-down direction 7 and the front-rear direction 8. The protrusion 30 protrudes upward from the rear end of the plate body 10 and extends rearward from the upper end. The tip 31 of the protrusion 30 extending rearward is located on the side (upper side) from which the projection 20 protrudes relative to the upper surface 11 of the plate body 10 in the up-down direction 7.

[0044] The distance R2 in the up-down direction 7 from the tip 31 of the protrusion 30 to the underside 12 of the plate body 10 is large enough for a user to insert their fingers between the tip 31 and the floor F to grasp the tip 31. The distance R2 is larger than the height H1 (see FIG. 6) in the up-down direction 7 from the upper side 11 of the plate body 10 to the tip 21 of the protrusion 20 (R2>H1). The length L7 of the tip 31 of the protrusion 30 in the front-rear direction 8 is large enough for a user to grasp the tip 31. The tip 31 of the protrusion 30 has an outer shape that is long in the left-right direction 9 in a plan view. The length of the tip 31 in the left-right direction 9 is shorter than the length L1 of the long side of the plate body 10. The tip 31 of the protrusion 30 is located at the center of the plate body 10 in the left-right direction 9. A front-facing surface 32 (see FIG. 4) of the protrusion 30 is separated from the protrusions 20e to 20h located on the rear end side in the front-rear direction 8.

[0045] (An example of how to use the film removal tool 1) Next, an example of a method for using the film remover 1 to remove the resin film 210 will be described with reference to FIGS.

[0046] As shown in FIG. 2, a case will be described as an example in which a resin film 210 is attached to the right end of the underside 110 of the door 100 and is sandwiched between the underside 110 and a floor F. First, the tip 31 of the protrusion 30 is held by a user with the upper surface 11 of the plate body 10 facing upward. As shown in FIGS. 6 and 7, the film remover 1 held by the user is inserted between the underside 110 of the door 100 and the floor F to the left of the right end of the underside 110 of the door 100. For example, by moving the front end of the plate body 10 forward, the plate body 10 and the protrusion 20 are inserted between the underside 110 of the door 100 and the floor F from the side of one main surface of the door 100 (for example, the rear).

[0047] Next, the tips 21 of the protrusions 20 aligned in the front-rear direction 8 are aligned with the underside 110 of the door 100 in the front-rear direction 8. After alignment, the tips 31 of the convex portions 30 are lifted upward, so that the plate body 10 and the protrusions 20 are pressed against the underside 110 of the door 100. As a result, the plate body 10 is elastically deformed in the up-down direction 7 with the tips 21 of the plate body 10 and the protrusions 20 pressed against the underside 110 of the door 100. In this state, the user moves the tips 31 of the convex portions 30 to the right. As a result, the tips 21 of the protrusions 20 move rightward while being pressed against the underside 110 of the door 100.

[0048] When the tips 21 of the protrusions 20 reach the position of the resin film 210, either of the tips 21 of the protrusions 20 located in the left region 11b on the upper surface 11 of the plate body 10 bites into the resin film 210 or enters between the resin film 210 and the underside 110 of the door 100. When the film removal tool 1 is further slid rightward, the resin film 210 moves rightward together with the tips 21 of the protrusions 20. As a result, the resin film 210 is peeled off from the underside 110 of the door 100. As shown in FIG. 8 , the resin film 210 peeled off from the underside 110 of the door 100 is separated from the door 100 together with the film removal tool 1 while entangled with the tips 21 of the protrusions 20. As a result, the resin film 210 is scraped off and removed from the underside 110 of the door 100.

[0049] Although not explained in detail using drawings, when the film removal tool 1 is moved to the left in the left-right direction 9, one of the tips 21 of the protrusions 20 located in the right-hand region 11a on the upper surface 11 of the plate body 10 bites into the resin film 210 or penetrates between the resin film 210 and the underside 110 of the door 100, thereby scraping and removing the resin film 210 from the underside 110 of the door 100.

[0050] (Effects of the embodiment) When the plate body 10 is inserted between the lower surface 110 of the door 100 and the floor surface F and the protrusion 20 is pressed against the lower surface 110 of the door 100, the plate body 10 is slid, and the tip 21 of the protrusion 20 moves while biting into the resin film 210 attached to the lower surface 110 of the door 100. As a result, the resin film 210 into which the tip 21 of the protrusion 20 has bitten is peeled off from the lower surface 110 of the door 100.

[0051] The force pressing the protrusions 20 against the underside 110 of the door 100 causes the protrusions 20 to elastically deform, so that the underside 110 of the door 100 is less likely to be damaged by contact with the tips 21 of the protrusions 20. Furthermore, even if the plate 10 moves slightly away from the underside 110 of the door 100 when the plate 10 is slid, the state in which the tips 21 of the protrusions 20 contact the underside 110 of the door 100 is maintained.

[0052] Since both the plate body 10 and the projections 20 are made of resin, the manufacturing cost can be reduced.

[0053] Since the protrusion 30 serves as a handle, the plate 10 can be easily slid while inserted between the lower surface 110 of the door 100 and the floor surface F.

[0054] Since the tip 31 of the protrusion 30 is separated from the floor surface F, the tip of the protrusion 30 is easy to hold.

[0055] The protrusion 20 abuts against the underside 110 of the door 100 while the protrusion 30 is separated from the surface of the door 100, providing good operability.

[0056] By inserting the plate body 10 between the underside 110 and the floor surface F so that the front-to-rear direction 8 is the thickness direction of the door 100, one of the protrusions 20 can easily bite into the resin film 210 attached to the underside 110 of the door 100.

[0057] When the plate body 10 is slid in either the left or right direction 9, the tip 21 of one of the projections 20 bites into the resin film 200.

[0058] Since the through holes 24 formed by cutting and raising the projections 20 from the plate 10 are spaced apart relatively far from each other, cracks and the like are unlikely to occur in the plate 10 around the through holes 24 .

[0059] Since the distance between the tips 21 of the protrusions 20a, 20e located at both ends in the front-to-rear direction 8 is close to the overall length of the protrusions 20a to 20e lined up in the front-to-rear direction 8, the protrusions 20 also easily dig into the resin film 200 located at the end of the door 100 in the thickness direction.

[0060] (Variation) In the above embodiment, the outer shape of the plate body 10 is rectangular in plan view, but is not limited to this. As long as a plurality of protrusions 20 are arranged in the front-rear direction 8 and the left-right direction 9, various shapes such as a disk shape or a polygonal shape may be adopted as the shape of the plate body 10.

[0061] Furthermore, in the above embodiment, the entire film removal tool 1 may be integrally molded from synthetic resin, but this is not limited to this. The plate body 10 and the protrusion 20 may be integrally molded from synthetic resin, and the convex portion 30 may be attached to the plate body 10 as a separate body. The film removal tool 1 may also be formed by cutting and folding a synthetic resin plate, or may be molded using an injection molding machine, a compression molding machine, or the like. The entire film removal tool 1 is not limited to being made from synthetic resin, and may be integrally molded from metal, or a combination of synthetic resin and metal.

[0062] Furthermore, in the above embodiment, it has been described that the protrusions 20 located in the right region 11a on the top surface 11 of the plate body 10 protrude from the top surface 11 of the plate body 10 toward the tip 21 so as to have a rightward component. Also, it has been described that the protrusions 20 located in the left region 11b on the top surface 11 of the plate body 10 protrude from the top surface 11 of the plate body 10 toward the tip 21 so as to have a leftward component, but this is not limited to this. Without being limited to the right region 11a and the left region 11b on the top surface 11 of the plate body 10, some of the protrusions 20 may protrude from the top surface 11 of the plate body 10 toward the tip 21 so as to have a rightward component. Other parts of the protrusions 20 may protrude from the top surface 11 of the plate body 10 toward the tip 21 so as to have a leftward component.

[0063] In the above embodiment, the protrusion 30 protrudes from the rear end of the plate body 10, but this is not limiting. The protrusion 30 may protrude from the front end of the plate body 10.

[0064] In the above embodiment, the protrusions 20 are described as having a triangular shape, but this is not limiting. The protrusions 20 may be, for example, rectangular. The tips 21 of the protrusions 20 may be wavy tips 21 that combine multiple tapered structures. The protrusions 20 may also be pyramidal, such as triangular pyramids, quadrangular pyramids, or cones. The protrusions 20 may be attached to the upper surface 11 of the plate 10 by combining an elastic body such as a spring or rubber with a tapered tip 21. The protrusions 20 may also be needle-like bodies with tapered tips 21.

[0065] In the above embodiment, the cross section of the protrusion 30 is L-shaped, but this is not limiting. Various structures can be employed as long as the tip 31 of the protrusion 30 is located on the side where the projection 20 protrudes from the upper surface 11 of the plate body 10 in the vertical direction 7. For example, the protrusion 30 may be configured to have a curved cross section.

[0066] In the above embodiment, the protrusions 20 arranged in the front-rear direction, and the protrusions 20 located at the front and rear ends, are described as having a right-angled triangle shape, but this is not limited thereto. As shown in Fig. 9, of the two interior angles A1, A2 other than the interior angle located at the tip 21 of the protrusion 20, the interior angle A1 located at one end may be larger than the other interior angle A2 (A1 > A2) and smaller than a right angle.
