Abstract
Description
[Technical Field]
[0001] The present invention relates to an interior fixture for attaching thin and lightweight interior items such as mirrors, picture frames, or shelves to a wall surface in a room, and to an interior mounting structure using this interior fixture. [Background technology]
[0002] There are times when it is desirable to attach thin and lightweight interior items such as mirrors, picture frames, or shelves to the interior walls of a house. Various types of interior fixtures for attaching these interior items to interior walls are sold at home improvement stores and the like.
[0003] However, most interior fixtures sold at home improvement stores and similar establishments are attached to the interior walls of homes using wood screws, pins, etc. This means that these interior fixtures can damage the interior walls with the wood screws and pins, etc. When considering moving out of a home, it is important to avoid damaging the interior walls as much as possible.
[0004] Therefore, the inventors have noticed that staples (hereinafter referred to as staples) driven into the interior walls of a house, particularly staples driven into the wall at an angle diagonally downward, can support a fairly large load.
[0005] In other words, the interior of a house is often partitioned and its walls are made of gypsum board. Gypsum board is relatively soft, and it is possible to drive staples into it. A staple driven into gypsum board would likely be able to support interior items weighing as little as a thin, lightweight mirror, picture frame, or shelf.
[0006] Therefore, the present inventors have proposed a novel interior fixture for attaching an interior item to a wall surface inside a house with staples, as shown in Figures 5 and 6. Here, Figure 5 is a perspective view showing an interior item (mirror) attached to a wall surface with staples, and Figure 6 is a cross-sectional view taken along the line BB in Figure 5.
[0007] As shown in these figures, this new interior mounting fixture involves first stacking a wall-hanging aid 14 on a wall 10 inside a house at the location where the interior 12 is to be attached, then driving staples 16 into the stacked wall-hanging aids 14 from the inside of the room toward the wall 10, and attaching the wall-hanging aids 14 to the wall 10 with the driven staples 16.
[0008] Next, double-sided adhesive tape 18 is prepared, the release paper on one side (back side) of double-sided adhesive tape 18 is peeled off to expose the adhesive surface, and the exposed adhesive surface of double-sided adhesive tape 18 is brought into close contact with wall-hanging aid 14 attached to wall surface 10 with staples 16, and double-sided adhesive tape 18 is attached to wall-hanging aid 14.
[0009] Next, the release paper on the other side (front side) of the attached double-sided adhesive tape 18 is peeled off, and the mounting back surface 12a on the back side of the interior 12 is adhered to the exposed adhesive surface of the double-sided adhesive tape 18, and the interior 12 is attached to the wall surface 10.
[0010] Here, the wall-hanging aid 14 comprises a fixed base 14a that contacts the wall surface 10 and a cushioning material 14b that is adhered to the fixed base 14a with an adhesive. The cushioning material 14b is adhered to the fixed base 14a so that the heads 16a of the staples 16 are embedded in the cushioning material 14b and the double-sided adhesive tape 18 can be completely attached to the mounting back surface 12a on the back side of the interior 12.
[0011] After the interior 12 is attached to the wall surface 10, if it becomes necessary to remove the interior 12 from the wall surface 10 at a later date, the interior 12 can be easily removed from the wall surface 10 together with the double-sided adhesive tape 18, the wall-hanging aid 14 and the staples 16 by lifting the interior 12 obliquely upward.
[0012] This interior fixture is fixed to the wall surface 10 only by staples 16, so that after the interior 12 is removed, only holes from the staples 16 remain on the wall surface 10, which are so small as to be negligible, and the wall surface 10 remains very clean after the interior 12 is removed.
[0013] However, a force is constantly acting between the mounting back surface 12a of the interior 12 and the double-sided adhesive tape 18 due to the weight of the interior 12, trying to pull them apart. However, if the interior 12 and the double-sided adhesive tape 18 are in complete contact with each other, the adhesive strength will withstand this force, and the interior 12 and the double-sided adhesive tape 18 will be firmly adhered and connected.
[0014] However, due to manufacturing reasons, the mounting back surface 12a of the interior 12 may not be flat, which may result in incomplete adhesion between the interior 12 and the double-sided adhesive tape 18.These incomplete areas may then be the starting point for the aforementioned peeling force to gradually peel away the adhesion between the interior 12 and the double-sided adhesive tape 18, causing the interior 12 to peel off from the wall surface 10.
[0015] Furthermore, the humidity level in a home often changes significantly due to cooking, the use of heaters, the use of humidifiers, etc. If the humidity level changes significantly, the interior 12, if made of wood, may warp, for example, as indicated by arrow A in FIG. 6.
[0016] When the interior 12 warps, the gap H between the rear mounting surface 12a of the interior 12 and the wall surface 10 widens at the warped portion, and the double-sided adhesive tape 18 gradually peels off from the rear mounting surface 12a of the interior 12 and the surface of the cushioning material 14b, which may gradually reduce the strength of attachment of the interior 12 to the wall surface 10.
[0017] Furthermore, even if care is taken, people or objects may occasionally hit the interior piece 12 attached to the wall surface 10 of a room. If people or objects repeatedly hit the interior piece 12 over a long period of time, the adhesion between the mounting back surface 12a of the interior piece 12 and the double-sided adhesive tape 18, and the adhesion between the double-sided adhesive tape 18 and the cushioning material 14b, may loosen, causing the adhesive surface of the double-sided adhesive tape 18 to gradually peel off from the mounting back surface 12a and the wall surface 10, gradually reducing the strength of the attachment of the interior piece 12 to the wall surface 10.
[0018] Furthermore, in the interior fixture described above, wall-hanging auxiliary fixture 14 is made by bonding cushion material 14b to fixed base 14a. However, when the interior fixture is constructed in this manner, cushion material 14b bonded to fixed base 14a must be specially ordered, which raises the problem of increased costs for the interior fixture.

[0019] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-282769 [Patent Document 2] Japanese Patent Application Laid-Open No. 2008-206917 Summary of the Invention [Problem to be solved by the invention]
[0020] The problem to be solved by the present invention is to reduce the cost of interior fixtures and to prevent a decrease in the mounting strength of interior fixtures mounted on a wall surface. [Means for solving the problem]
[0021] The interior fixture of the present invention comprises a sheet-like base forming material that can be attached with staples to the wall surface to which the interior is to be attached, and double-sided adhesive tape for attaching the back of the interior to the base forming material, the base forming material being made of a single-layer EVA foam sheet for sewing.
[0022] In addition, the interior mounting structure of the present invention comprises a sheet-like base forming material attached to a wall surface with staples, double-sided adhesive tape attached to the base forming material, and an interior attached to the double-sided adhesive tape, and the base forming material is made of a single-layer EVA foam sheet for sewing.
[0023] Here, EVA foam refers to a foam primarily made of ethylene-vinyl acetate copolymer. EVA foam for sewing has an expansion ratio of 4 to 6 times and a tear strength of approximately 70 to 100 N / cm. The thickness of the sheet-like base forming material is preferably 1 mm to 2 mm when using No. 10 staples.
[0024] Alternatively, a flat synthetic resin or metal plate may be attached to the back surface of the interior with nails or staples, and the interior may be attached to the double-sided adhesive tape via the synthetic resin or metal plate. When the interior is attached to the double-sided adhesive tape via the synthetic resin or metal plate, the interior adheres strongly to the double-sided adhesive tape, improving the strength with which the interior is attached to the wall surface. [Effects of the Invention]
[0025] The present invention has the advantage that, since the base forming material is made of a sewing EVA foam sheet, even if the humidity in the room changes and the back surface of the interior warps, the base forming material will expand in the thickness direction, maintaining adhesion between the double-sided adhesive tape and the back surface of the attachment, and between the double-sided adhesive tape and the base forming material, thereby maintaining the strength of attachment to the wall surface of the interior.
[0026] In addition, since the base forming material of the present invention is made of a sewing EVA foam sheet, even if a person or object hits the interior and an impact is applied that causes the adhesion to peel off between the back surface of the interior and the double-sided adhesive tape, or between the double-sided adhesive tape and the base forming material, the base forming material will stretch in the thickness direction, maintaining the adhesion between the back surface of the interior and the double-sided adhesive tape and between the double-sided adhesive tape and the base forming material, thereby having the advantage of maintaining the strength of attachment to the wall surface of the interior.
[0027] Furthermore, since the base forming material of the present invention is formed from a single layer of sewn EVA foam sheet, there is no need to incur the expense of custom-made products in which cushioning material is bonded to a fixed base, as was done in the past, and therefore there is an advantage in that interior fittings can be provided at low cost.
[0028] In addition, in the present invention, since the base forming material is formed from a single layer of sewing EVA foam sheet, the base forming material can be made thin, the legs of the staples that penetrate the base forming material can be made long, and the staples can be inserted deep into the wall, which has the advantage that the base forming material can be firmly attached to the wall surface and the interior can be firmly attached to the wall surface. [Brief explanation of the drawings]
[0029] [Figure 1] FIG. 1 is a perspective view showing an interior (shelf) attached to a wall surface with staples (Example 1). [Figure 2] 2 is a cross-sectional view taken along the line AA in FIG. 1. (Example 1) [Figure 3] Fig. 3 is an enlarged view of the main part of Fig. 2 (Example 1) [Figure 4] FIG. 4 is an enlarged view of the main part of the second embodiment. (Second embodiment) [Figure 5] FIG. 5 is a perspective view showing an interior (mirror) attached to a wall surface with staples. [Figure 6] FIG. 6 is a cross-sectional view taken along the line BB in FIG. DETAILED DESCRIPTION OF THE INVENTION
[0030] To achieve the object of attaching lightweight interior items such as mirrors, picture frames or small shelves to a wall surface at a minimum cost without leaving any noticeable damage on the wall surface. [Example]
[0031] FIG. 1 is a perspective view showing an interior (shelf) attached to a wall surface with staples, FIG. 2 is a cross-sectional view taken along the line AA in FIG. 1, and FIG. 3 is an enlarged view of the main part of FIG. 2. As shown in these figures, a small shelf (interior 12) is attached to a wall surface 10 using an interior mounting fixture according to the present invention.
[0032] That is, as shown in Figures 2 and 3, a base forming material 20 is fixed to the wall surface 10 with a plurality of staples 16. Here, the base forming material 20 is made of an EVA foam sheet for sewing. EVA foam refers to a foam made mainly of ethylene-vinyl acetate copolymer (Ethylene-Vinyl Acetate). The EVA foam for sewing has a high tear strength of 70 to 100 N / cm and an expansion ratio of about 4 to 6 times.
[0033] In this example, the EVA foam sheet for sewing is "5x foam for sewing" manufactured and sold by Daiichi Chemical Co., Ltd., but equivalent products from other companies may also be used as long as their tear strength is within the above numerical range.
[0034] Any size of staple 16 may be used, but size 10 staple 16 is preferred because it is desired to make the hole after removing staple 16 as small as possible. When using size 10 staple, the allowable range for the thickness of base forming material 20 is 0.5 mm to 2.5 mm.
[0035] If the thickness of the base forming material 20 is less than 0.5 mm, the heads 16a of the staples 16 are difficult to embed inside the base forming material 20, and the heads 16a of the staples 16 protrude from the base forming material 20, making it difficult to achieve complete adhesion between the double-sided adhesive tape 18 and the base forming material 20, and between the double-sided adhesive tape 18 and the interior.
[0036] If the thickness of the base forming material 20 exceeds 2.5 mm, the length of the legs 16b of the staples 16 that penetrate into the gypsum board will be shortened, reducing the holding power of the legs 16b of the staples 16. Taking these factors into consideration, a more preferable thickness of the base forming material 20 is 1 mm to 2 mm.
[0037] The staples 16 may be driven either vertically or horizontally, but when the staples 16 are driven horizontally, the support strength to the interior 12 is increased by driving the legs 16b of the staples 16 at an angle diagonally downward inside the wall surface 10.
[0038] Commercially available staples can be used as staples 16, but stainless steel staples are preferable if possible because the gypsum board that forms wall surface 10 is alkaline. Wall materials other than gypsum may also be used as long as they form a flat, hard surface.
[0039] Double-sided adhesive tape 18 is attached to the front surface of base forming material 20 fixed with staples 16. While commercially available strong double-sided adhesive tape is preferred, tape that can be easily peeled off after application is particularly preferred. The mounting back surface 12a of interior 12 is attached to the front surface of double-sided adhesive tape 18 attached to base forming material 20.
[0040] In this embodiment, a small shelf is used as an example of the type of interior item 12, but any lightweight item that can be attached to the wall surface 10, such as a mirror or picture frame, can be used. The allowable size range for the interior item 12 that can be attached in this invention is a thickness:height ratio of 1:3 to 5, with a thickness:height ratio of approximately 1:3 being particularly preferable. The allowable weight limit for the interior item 12 that can be attached to the wall surface with staples 16 is approximately 10 kg.
[0041] Next, a method for attaching an interior to a wall surface using the interior fixture according to the present invention will be described.
[0042] First, the base forming material 20 is attached to the wall surface 10 at the location where the interior 12 is to be attached using a plurality of staples 16. The staples 16 are driven evenly across the entire surface of the base forming material 20. If the staples 16 are driven diagonally downward, the downward pulling strength is improved, allowing a heavier interior 12 to be attached.
[0043] The heads 16a of the staples 16 driven into the base forming material 20 are embedded inside the base forming material 20, and the front surface of the base forming material 20 becomes flat as a whole except for the area around the heads 16a of the staples 16.
[0044] Next, a double-sided adhesive tape 18 is prepared, the release paper on one side of the double-sided adhesive tape 18 is peeled off to expose the adhesive surface, and the exposed adhesive surface of the double-sided adhesive tape 18 is brought into close contact with a base forming material 20 attached to the wall surface 10 with staples 16, and the double-sided adhesive tape 18 is attached to the base forming material 20.
[0045] Next, peel off the release paper on the other side (front side) of the attached double-sided adhesive tape 18. The adhesive surface on the front side of the double-sided adhesive tape 18 is not pushed up by the staple heads and remains flat.
[0046] The mounting back surface 12a on the rear side of the interior 12 is brought into close contact with the exposed adhesive surface of the double-sided adhesive tape 18, and the interior 12 is attached to the wall surface 10. The mounting back surface 12a on the rear side of the interior 12 is in perfect contact with the double-sided adhesive tape 18.
[0047] In the interior fixture of the present invention, the base forming material 20 is made of a sewing EVA foam sheet with high tear strength, so even if the base forming material 20 is pulled strongly, the heads 16a of the staples 16 will not come out of the base forming material 20, and the base forming material 20 will not tear due to scratches or holes made by the legs 16b or heads 16a of the staples 16.
[0048] When it is desired to remove the interior 12 attached to the wall surface 10 from the wall surface 10, the interior 12 is removed together with the double-sided adhesive tape 18 attached to the back surface of the interior 12, the base forming material 20 to which the double-sided adhesive tape 18 is attached, and the staples 16 stuck in the base forming material 20. Here, if the staples 16 have been driven diagonally downward into the wall surface 10, the interior 12 is lifted up to remove it from the wall surface 10. [Example]
[0049] If the interior 12 is made of wood and the mounting back surface 12a on the rear side of the interior 12 is rough, the adhesive strength between the interior 12 and the double-sided adhesive tape 18 may be weakened. Fig. 4 is an enlarged view of a main part of Example 2. As shown in the figure, a thin synthetic resin plate 22 or metal plate may be attached to the mounting back surface 12a on the rear side of the interior 12 with nails 24 or screws.
[0050] If a thin synthetic resin plate 22 or a metal plate is firmly attached to the mounting back surface 12a on the rear side of the interior 12 with nails 24 or screws, the interior 12 will be completely adhered to the double-sided adhesive tape 18 via the synthetic resin plate 22 or the metal plate.
