Description

[Technical Field]

[0001] The present invention relates to a method for renovating a bathtub or washbasin. [Background technology]

[0002] BACKGROUND ART Conventionally, since it is difficult to replace old bathtubs in bathrooms, methods of renovating existing bathtubs have been proposed (see, for example, Patent Documents 1 and 2 listed below).

[0003] Specifically, Patent Document 1 below discloses a renovated bathtub that includes an existing bathtub and a new bathtub cover body that is molded integrally in advance and fixed to the interior of the existing bathtub, wherein the bathtub cover body has a shape similar to the inner surface of the existing bathtub, and multiple ribs are formed on at least the outer peripheral surface of the side wall, and the renovated bathtub is fixed to the inner surface of the existing bathtub by the outermost peripheral portions of the multiple ribs.

[0004] Meanwhile, Patent Document 2 below discloses a method for repairing an enamel bathtub, which is characterized by sequentially carrying out a sanding process to remove deteriorated portions of the enamel bathtub surface, a primer process in which 7.5 to 30 parts by weight of an aminosilane coupling agent is diluted with a solvent and mixed with a curing agent obtained by diluting 100 parts by weight of a resin with a solvent, and the curing agent mixture is then mixed with a bisphenol-based epoxy resin and applied as a paint, and a topcoat process in which a urethane resin paint is applied.

[0012] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, the drawings used in the following description may show characteristic parts in a schematic manner for the sake of convenience in order to make the features easier to understand, and the dimensional ratios of the components may not necessarily be the same as those in reality. Furthermore, the materials, dimensions, etc. exemplified in the following description are merely examples, and the present invention is not necessarily limited to them, and can be implemented with appropriate changes within the scope that does not change the gist of the present invention.

[0013] (First embodiment) A bathtub renovating method according to a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a flowchart illustrating a method for renovating a bathtub 1. FIG. 2 is a perspective view showing the bathtub 1 before a wrapping sheet 2 is attached. FIG. 3 is a perspective view showing the bathtub 1 after a wrapping sheet 2 has been attached. FIG. 4 to FIG. 6 are cross-sectional views illustrating the method for renovating a bathtub 1 in order. FIG. 7 and FIG. 8 are cross-sectional views illustrating another method for renovating a bathtub 1.

[0014] The bathtub renovation method of this embodiment is characterized by carrying out, in the order shown in the flowchart of Figure 1, the steps of preparing a bathtub wrapping sheet 2 large enough to cover the surface of the bathtub 1 (hereinafter referred to as the "preparation step") S101, attaching the wrapping sheet 2 to the surface of the bathtub 1 according to the shape of the bathtub 1 (hereinafter referred to as the "wrapping step") S102, and removing any excess portion of the wrapping sheet 2 attached to the surface of the bathtub 1 (hereinafter referred to as the "finishing step") S103.

[0015] As a result, by attaching the wrapping sheet 2 shown in Figure 3 to the bathtub 1 installed in the bathroom shown in Figure 2, the existing bathtub 1 can be renovated easily and in a short time.

[0016] Specifically, when renovating the bathtub 1, first, in the preparation step S101 shown in Fig. 1, a single-layer or multi-layer resin sheet that is highly waterproof and extensible or stretchable is prepared as the bathtub wrapping sheet 2. Furthermore, it is preferable to thoroughly dry the surface of the bathtub 1 before construction after cleaning.

[0017] The wrapping sheet 2 is made of, for example, a soft vinyl chloride resin sheet, a polyethylene sheet, an EVA sheet, a polyurethane sheet, etc. In this embodiment, the wrapping sheet 2 is made of a soft vinyl chloride resin sheet.

[0018] An adhesive layer (not shown) is provided in advance over the entire back surface of the wrapping sheet 2. The adhesive layer is made of a pressure-sensitive adhesive such as an acrylic adhesive or a rubber adhesive. In this embodiment, an acrylic adhesive is used as the adhesive (adhesive layer).

[0019] On the other hand, wrapping sheet 2 is not necessarily limited to having an adhesive layer on the back surface, and may be one that does not have an adhesive layer. In this case, when attaching wrapping sheet 2 to the surface of bathtub 1 described below, it is also possible to apply adhesive to the surface of bathtub 1 or the back surface of wrapping sheet 2.

[0020] Next, in the wrapping step S102 shown in Fig. 1, double-sided tape 3 for temporary attachment is attached around the entire periphery of the opening of bathtub 1, as shown in Fig. 4. Then, as shown in Fig. 5, a wrapping sheet 2 large enough to cover the surface of bathtub 1 is placed over bathtub 1, and attached around the periphery of the opening of bathtub 1 via double-sided tape 3 for temporary attachment.

[0021] At this time, it is preferable to cover the bathtub 1 with the wrapping sheet 2 loosened from the opening toward the inside of the bathtub 1. The degree of loosening of the wrapping sheet 2 can be adjusted appropriately according to the degree of stretching of the wrapping sheet so that no wrinkles or air bubbles are formed in the wrapping sheet 2 after application. If a wrapping sheet that stretches easily is used, it can be applied without loosening.

[0022] From this state, as shown in Figure 6, the wrapping sheet 2 is stretched to fit the shape of the bathtub 1 and attached to the surface of the bathtub 1. At this time, the wrapping sheet 2 is attached to the surface of the bathtub 1 while removing the air between the surface of the bathtub 1 and the wrapping sheet 2 using a jig 101 such as a roller or squeegee to prevent wrinkles or air bubbles from forming in the wrapping sheet 2.

[0023] In addition, for areas where it is difficult to attach the wrapping sheet 2, such as the corners of the bathtub 1, it is preferable to use a heater 102, such as a heat gun, to apply heat to the wrapping sheet 2, making it easier to stretch the wrapping sheet 2, and then attach the wrapping sheet 2 to the surface of the bathtub 1.

[0024] In addition, to make it easier to attach the wrapping sheet 2 to the surface of the bathtub 1, for example, water with a small amount of neutral detergent dissolved in it may be sprayed onto the surface of the bathtub 1, and then the wrapping sheet 2 may be attached to the surface of the bathtub 1.

[0025] It is also preferable to apply the wrapping sheet 2 from the center, where the surface to be applied is larger, toward the edges. It is also preferable to apply the wrapping sheet 2 from the bottom surface of the bathtub 1 toward the side, and also from the bottom to the top of the side of the bathtub 1. Finally, after removing the double-sided tape 3, the wrapping sheet 2 is applied to a position that covers the periphery of the opening of the bathtub 1. However, if necessary, it is not necessary to remove the double-sided tape 3.

[0026] Next, in the finishing step S103 shown in FIG. 1, the excess portion of the wrapping sheet 2 attached to the surface of the bathtub 1 is cut and removed using a blade (not shown) such as a cutter.

[0027] Specifically, as shown in Figure 3, the excess portion of the wrapping sheet 2 is cut and removed along the edge around the opening of the bathtub 1, and the excess portion of the wrapping sheet 2 is cut and removed along the edge around the drain outlet 1a of the bathtub 1. By going through the above steps, the renovation of the bathtub 1 is completed.

[0028] In the method for renovating a bathtub 1 of this embodiment, by attaching a wrapping sheet 2 to the bathtub 1 installed in the bathroom described above, it is possible to renovate the bathtub 1 relatively easily and in a short time without replacing the existing bathtub 1.

[0029] In addition, since there is no need to discard the existing bathtub 1, waste is reduced and it is environmentally friendly. Furthermore, it can be installed regardless of the size or shape of the bathtub 1. Furthermore, it is possible to prepare a wide variety of colors and designs for the wrapping sheet 2.

[0030] Furthermore, the wrapping sheet 2 has high chemical resistance and can withstand long-term use. Furthermore, the wrapping sheet 2 can be repeatedly replaced on the bathtub 1.

[0031] As described above, the method for renovating the bathtub 1 of this embodiment is easy to carry out and can be completed in a short time.

[0032] The present invention is not necessarily limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0033] Specifically, in the wrapping step S102 shown in FIG. 1, the air between the surface of the bathtub 1 and the wrapping sheet 2 may be forcibly removed using a vacuum pump 103 as shown in FIG.

[0034] In this case, with duct 103a connected to vacuum pump 103 connected to drain outlet 1a of bathtub 1, it is possible to firmly attach wrapping sheet 2 to the surface of bathtub 1 while sucking out air between the surface of bathtub 1 and wrapping sheet 2. Note that vacuum pump 103 may also be connected to a water supply port.

[0035] The duct 103a of the vacuum pump 103 can be connected to the drain outlet 1a of the bathtub 1 from the back side of the bathtub 1 through a maintenance hole (not shown) provided in the bathroom. Alternatively, the connection can be made from the front side of the bathtub 1 through a portion obtained by cutting off the excess portion of the wrapping sheet 2 around the drain outlet 1a of the bathtub 1.

[0036] 1, the wrapping sheet 2 may be attached to the surface of the bathtub 1 while hot water (or room temperature water) W is poured into the bathtub 1, as shown in Fig. 8. This allows the wrapping sheet 2 to be attached along the shape of the bathtub 1 while being stretched by the water pressure and heat from the hot water W.

[0037] (Second embodiment) A method for renovating a washbasin according to a second embodiment of the present invention will be described with reference to FIGS. 1, 9 and 10. FIG. 9 is a perspective view showing the washbasin 50 with the wrapping sheet 2 attached thereto. FIG. 10 is a cross-sectional view showing the washbasin 50 with the wrapping sheet 2 attached thereto.

[0038] In this embodiment, as shown in FIGS. 9 and 10, when renovating a washbasin 50, the same renovation method as when renovating the bathtub 1 can be applied.

[0039] That is, the method for renovating a washbasin to which the present invention is applied follows the flowchart shown in Figure 1 above, and includes the following steps in this order: a preparation step S101 of preparing a washbasin wrapping sheet 2 large enough to cover the surface of the washbasin 50; a wrapping step of attaching the wrapping sheet 2 to the surface of the washbasin 50 according to the shape of the washbasin 50; and a finishing step S103 of removing any excess portion of the wrapping sheet 2 attached to the surface of the washbasin 50. In this way, by attaching the wrapping sheet 2 to the washbasin 50 installed on the sink, it is possible to easily and quickly renovate an existing washbasin 50.

[0040] Specifically, when renovating the washbasin 50, first, in the preparation step S101 shown in Fig. 1, the wrapping sheet 2 is prepared as a wrapping sheet for the washbasin. Furthermore, it is preferable to thoroughly dry the surface of the washbasin 50 before construction after cleaning.

[0041] 1, double-sided tape 3 (not shown) for temporary attachment is attached around the entire periphery of the opening of washbasin 50. After that, a wrapping sheet 2 large enough to cover the surface of washbasin 50 is placed over washbasin 50, and then attached around the periphery of the opening of washbasin 50 via double-sided tape 3 to temporarily secure it.

[0042] At this time, it is preferable to place the wrapping sheet 2 in a loosened state from the opening of the washbasin 50 toward the inside of the washbasin 50. The degree of loosening of the wrapping sheet 2 can be adjusted appropriately depending on the degree of stretch of the wrapping sheet so that no wrinkles or air bubbles are formed in the wrapping sheet 2 after application. If a wrapping sheet that stretches easily is used, it can be applied without loosening.

[0043] From this state, wrapping sheet 2 is stretched to fit the shape of washbasin 50 and attached to the surface of washbasin 50. At this time, using a jig 101 such as a roller or squeegee, wrapping sheet 2 is attached to the surface of washbasin 50 while removing air between the surface of washbasin 50 and wrapping sheet 2 so as to prevent wrinkles or air bubbles from forming in wrapping sheet 2.

[0044] In addition, for areas of the washbasin 50 where it is difficult to attach the wrapping sheet 2, it is preferable to use a heater 102, such as a heat gun, to apply heat to the wrapping sheet 2, making it easier to stretch the wrapping sheet 2, and then attach the wrapping sheet 2 to the surface of the washbasin 50.

[0045] In addition, to make it easier to attach the wrapping sheet 2 to the surface of the washbasin 50, for example, water with a small amount of neutral detergent dissolved in it may be sprayed onto the surface of the washbasin 50, and then the wrapping sheet 2 may be attached to the surface of the washbasin 50.

[0046] It is also preferable to apply the wrapping sheet 2 from the bottom to the top of the washbasin 50. Finally, after removing the double-sided tape 3, the wrapping sheet 2 is applied to a position that covers the periphery of the opening of the washbasin 50. However, if necessary, the double-sided tape 3 does not need to be removed.

[0047] Next, in the finishing process S103 shown in Figure 1, after the wrapping sheet 2 is attached, the excess portion of the wrapping sheet 2 attached to the surface of the washbasin 50 is cut and removed using a blade such as a cutter (not shown).

[0048] Specifically, the excess portion of the wrapping sheet 2 is cut and removed along the edge around the opening of the washbasin 50, and the excess portion of the wrapping sheet 2 is cut and removed along the periphery of the drain outlet 50a of the washbasin 50. By going through the above steps, the repair of the washbasin 50 shown in FIGS. 9 and 10 is completed.

[0049] In the method for renovating the washbasin 50 of this embodiment, the air between the surface of the bathtub 1 and the wrapping sheet 2 may be forcibly removed using the vacuum pump 103 described above.

[0050] In this case, with the duct 103a connected to the vacuum pump 103 connected to the drain outlet 50a of the washbasin 50, it is possible to firmly attach the wrapping sheet 2 to the surface of the washbasin 50 while sucking out the air between the surface of the washbasin 50 and the wrapping sheet 2.

[0051] Furthermore, in the method for renovating the washbasin 50 of this embodiment, the wrapping sheet 2 may be attached to the surface of the washbasin 50 while pouring hot water (or room temperature water) W into the washbasin 50. This allows the wrapping sheet 2 to be attached along the shape of the washbasin 50 while being stretched by the water pressure and heat from the hot water W.

[0052] As described above, in the method of renovating a washbasin 50 of this embodiment, by attaching a wrapping sheet 2 to the washbasin 50 installed on the above-mentioned sink, it is possible to renovate the existing washbasin 50 relatively easily and in a short time without replacing it.

[0053] In addition, since the existing washbasin 50 does not need to be discarded, waste is reduced and it is environmentally friendly. Furthermore, it can be installed regardless of the size or shape of the washbasin 50. Furthermore, it is possible to prepare a wide variety of colors and designs for the wrapping sheet 2.

[0054] Furthermore, the wrapping sheet 2 has high chemical resistance and can withstand long-term use. Furthermore, the wrapping sheet 2 can be repeatedly replaced on the washbasin 50.

[0055] As described above, the method for renovating the washbasin 50 of this embodiment is easy to implement and can be completed in a short time. [Explanation of symbols]
