[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 the like in houses are covered with a resin film or the like for protection. The resin film is adhered to, for example, the bottom or top surface of the door, which is the end surface. After the door is installed in the house, the resin film is removed from the door. At that time, a part of the resin film may remain on the end surface of the door. In particular, there is a problem 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 consideration 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) The 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 having a tapered tip.

[0007] The plate is inserted between the bottom surface of the door and the floor, and the plate is slid with the protrusion pressed against the bottom surface of the door, causing the protrusion to move while biting into the resin film attached to the bottom surface of the door. As a result, the resin film that the protrusion has bitten into is peeled off from the bottom surface of the door.

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

[0009] The force of the projection pressing against the underside of the door causes the projection to elastically deform, so the underside of the door is less likely to be damaged by the projection abutting against it. Also, even if the plate moves slightly away from the underside of the door when it is slid, the projection will remain in abutment against the underside of the door.

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

[0011] Since both the plate 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 protruding portion serves as a handle, making it easy to slide the plate when it is inserted between the bottom surface of the door and the floor surface.

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

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

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

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

[0018] (7) The protrusions may be multiple 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 multiple protrusions may protrude from the main surface toward their tips so as to have a one-sided component in a second direction intersecting the first direction and a thickness direction of the plate, and other some of the multiple protrusions may protrude from the main surface toward their tips so as to have a other-sided component in the second direction.

[0021] No matter which direction the plate body is slid in in the second direction, the tip of one of the projections bites into the resin film.

[0022] (9) The multiple protrusions may be triangular and cut out from the plate, 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 projections from the plate are relatively far apart, cracks or the like are unlikely to occur in the plate around the through holes.

[0024] (10) Of the two interior angles of the protrusions aligned in the first direction 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 smaller 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 bite into the resin film located at the ends in the thickness direction of the door. Effect of the Invention

[0026] According to the present invention, the resin film attached to the lower surface of the door can be easily removed. [Brief description of the drawings]

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

[0029] Hereinafter, the directions related to the film removal tool 1 are indicated 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 perpendicular to each other. 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 surface of the plate body 10, and is a direction along the short side direction 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 surface of the plate body 10, and is a direction along the long side direction 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 upper and lower surfaces 110 of the door 100.

[0031] In FIG. 1, a knob and the like of the door 100 are omitted. In FIG. 1, the resin film 200 covers a half area located at the rear on the lower surface 110 of the door 100, but it may cover the entire upper and lower surfaces 110. The resin film 200 may cover both main surfaces, and may cover at least a part of the upper and lower surfaces 110 along the edges in the front-rear direction 8 on the upper and lower surfaces 110. The resin film 200 may be attached to the upper and lower surfaces 110 with an adhesive instead of heat welding. When the door 100 shown in FIG. 1 is attached to a closet or the like, the main surface on the rear side covered by the resin film 200 is attached so as to be the front surface.

[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 called the long side L3. The side along the front - rear direction 8 on the lower surface 110 of the door 100 is called the short side L4. As shown in FIG. 6, the dimension along the vertical direction 7 of the gap between the lower surface 110 of the attached door 100 and the floor surface F is called 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 molded 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 is rectangular in plan view. 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) of 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 about 2 to 3 cm, for example. 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 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 surfaces 11 of the plate body 10, the protrusions 20 located in the right region 11a protrude 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 surfaces 11 of the plate body 10, the protrusions 20 located in the left region 11b protrude 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 and has 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 bends 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 removing tool 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 protrusions 20 located on the most rear - 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 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. A 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] A distance R2 in the up-down direction 7 from the tip 31 of the protrusion 30 to the lower surface 12 of the plate body 10 is large enough for a user to insert a finger between the tip 31 and the floor surface F to pick up the tip 31. The distance R2 is larger than a height H1 (see FIG. 6) in the up-down direction 7 from the upper surface 11 of the plate body 10 to the tip 21 of the protrusion 20 (R2>H1). A length L7 in the front-rear direction 8 of the tip 31 of the protrusion 30 is long enough for a user to pick up 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 in the center of the plate body 10 in the left-right direction 9. A surface 32 (see FIG. 4) facing forward 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 remover 1) Next, an example of a method for removing the resin film 210 using the film remover 1 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 lower surface 110 of the door 100 and is sandwiched between the lower surface 110 and the floor surface F. First, the tip portion 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 FIG. 6 and FIG. 7, the film remover 1 held by the user is inserted between the lower surface 110 of the door 100 and the floor surface F to the left of the right end of the lower surface 110 of the door 100. For example, the front end of the plate body 10 is moved forward, so that the plate body 10 and the protrusion 20 are inserted between the lower surface 110 of the door 100 and the floor surface 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 bottom surface 110 of the door 100 in the front-rear direction 8. After the 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 bottom surface 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 bottom surface 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 bottom surface 110 of the door 100.

[0048] When the tip 21 of the projection 20 reaches the position of the resin film 210, either of the tips 21 of the projections 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 lower surface 110 of the door 100. When the film removal tool 1 is further slid rightward, the resin film 210 moves rightward together with the tip 21 of the projection 20. As a result, the resin film 210 is peeled off from the lower surface 110 of the door 100. As shown in FIG. 8, the resin film 210 peeled off from the lower surface 110 of the door 100 is separated from the door 100 together with the film removal tool 1 in a state where it is entangled with the tip 21 of the projection 20. As a result, the resin film 210 is scraped off and removed from the lower surface 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-side 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) The plate body 10 is inserted between the bottom surface 110 of the door 100 and the floor surface F, and the plate body 10 is slid with the protrusions 20 pressed against the bottom surface 110 of the door 100, whereby the tips 21 of the protrusions 20 move while biting into the resin film 210 attached to the bottom surface 110 of the door 100. As a result, the resin film 210 into which the tips 21 of the protrusions 20 have bitten is peeled off from the bottom surface 110 of the door 100.

[0051] Since the projection 20 is elastically deformed by the force of pressing the projection 20 against the underside 110 of the door 100, the underside 110 of the door 100 is less likely to be damaged by contact with the tip 21 of the projection 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 tip 21 of the projection 20 remains in contact with the underside 110 of the door 100.

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

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

[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] Since the projection 20 abuts against the lower surface 110 of the door 100 while the protruding portion 30 is separated from the surface of the door 100, the operability is good.

[0056] By inserting the plate 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, any 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 any 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 relatively far apart, cracks or 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-rear direction 8 is close to the overall length of the protrusions 20a to 20e aligned in the front-rear direction 8, the protrusions 20 easily dig into the resin film 200 located at the thickness-wise end of the door 100.

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

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

[0062] In the above embodiment, it has been described that the protrusion 20 located in the right region 11a on the top surface 11 of the plate body 10 protrudes 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 protrusion 20 located in the left region 11b on the top surface 11 of the plate body 10 protrudes 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 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 protrusion 20 is described as being triangular, but is not limited thereto. The protrusion 20 may be, for example, rectangular. The tip 21 of the protrusion 20 may be a wavy tip 21 that combines a plurality of tapered structures. The protrusion 20 may also be a pyramid such as a triangular pyramid, a quadrangular pyramid, or a cone. The protrusion 20 may be attached to the upper surface 11 of the plate body 10 by combining an elastic body such as a spring or rubber with a tapered tip 21. The protrusion 20 may be a needle-like body with a tapered tip 21.

[0065] In the above embodiment, the cross section of the protrusion 30 is L-shaped, but this is not limited thereto. 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, various structures can be adopted. 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 are in the shape of a right triangle at the front end and the rear end, but this is not limited thereto. As shown in Fig. 9, among the two interior angles A1, A2 other than the interior angle at the tip 21 of the protrusion 20, the one interior angle A1 located at one end may be larger than the other interior angle A2 (A1>A2) and smaller than a right angle. This also makes it possible to make the protrusion 20 bite into the resin film 200 located near both main surfaces of the door 100, compared to the case where the protrusion 20 is in the shape of an isosceles triangle.

[0067] In the above embodiment, the protrusions 20 are multiple, but the present invention is not limited to this. There may be only one protrusion 20. One protrusion 20 may protrude from the upper surface 11 of the plate body 10 toward the tip 21 so as to have a component facing to the right or left.
