[0009] 1. One embodiment (overview) A method for renovating a urinal according to one embodiment (hereinafter simply referred to as "the renovation method according to one embodiment") will be described with reference to the accompanying drawings. However, the renovation method according to one embodiment is merely one of various embodiments of the present disclosure, and various modifications are possible depending on the design, etc., as long as the object of the present disclosure can be achieved. Furthermore, each diagram showing the renovation method according to one embodiment is a schematic diagram, and the size and thickness of each component in the diagram, as well as their respective ratios, do not necessarily reflect the actual dimensional ratios.

[0010] The renovation method of one embodiment is a method of renovating an existing urinal 9 shown in, for example, FIG. 2 by attaching a urinal cover 1 made of synthetic resin so as to cover the entire urinal 9.

[0011] (Existing urinal) First, we will explain the structure of the existing urinal 9. The existing urinal 9 is a stall urinal exclusively for urination. In one embodiment, the existing urinal 9 is a wall-mounted type, but the existing urinal 9 may also be a floor-standing type.

[0012] The existing urinal 9 is a ceramic urinal that is long in the vertical direction, and has a bowl portion 92, left and right side walls 94, an upper wall 96, and a drain hole 98. The up and down, left and right, and front and back directions used in explaining the renovation method of one embodiment are based on the state in which a urinal cover 1 is installed to cover the existing urinal 9. The direction in which a user faces the existing urinal 9 and urinal cover 1 is the front, and the up and down, left and right, and front and back directions are perpendicular to each other.

[0013] The bowl portion 92 of the existing urinal 9 has a concavely curved surface. In other words, the surface of the bowl portion 92 is a concavely curved bowl surface. The surface of the bowl portion 92 includes a receiving surface 921 that is long in the vertical direction, and a bottom surface 925 that connects to the lower end of the receiving surface 921. The receiving surface 921 is formed as a concavely curved surface that is recessed backward. The bottom surface 925 is formed as a concavely curved surface that is recessed downward.

[0014] The left and right side walls 94 of the existing urinal 9 are positioned at a distance from each other in the left-right direction. The left and right side walls 94 form the left and right side end portions of the existing urinal 9.

[0015] The upper wall 96 of the existing urinal 9 is located above the bowl portion 92. The upper wall 96 forms the upper end portion of the existing urinal 9.

[0016] The drain hole 98 of the existing urinal 9 is formed in the bottom surface 925 of the bowl portion 92. The existing urinal 9 is originally configured so that urine and flushing water that hits the receiving surface 121 of the bowl portion 92 and flows down is collected on the bottom surface 925 and then discharged through the drain hole 98.

[0017] In the following, the word "existing" will be added to the beginning of each component of the existing urinal 9 to clearly distinguish it from the component of the urinal cover 1. In other words, the existing urinal 9 has an existing bowl portion 92, existing left and right side walls 94, an existing top wall 96, and an existing drain hole 98. In the existing urinal 9, the existing top wall 96 is located above the existing bowl portion 92.

[0018] The existing urinal 9 is made of ceramic, but the material of the existing urinal 9 is not particularly limited, and the existing urinal 9 may be made of, for example, synthetic resin.

[0019] (urinal cover) Next, we will explain the structure of the urinal cover 1. The urinal cover 1 has the outer shape of a stall urinal. In one embodiment, the urinal cover 1 is provided as a wall-mounted type, but it may also be provided as a floor-standing type.

[0020] The urinal cover 1 is a synthetic resin cover that is elongated in the vertical direction and has a bowl portion 12, left and right side walls 14, a top wall 16, and a drain hole 18. The urinal cover 1 is composed of a single resin molded product that is molded as a whole. In other words, the bowl portion 12, left and right side walls 14, and top wall 16 of the urinal cover 1 are molded as a single resin molded product. The urinal cover 1, which is a single resin molded product, can be molded, for example, by deforming a heated resin sheet along a mold. The urinal cover 1 can also be molded by other means, such as injection molding.

[0021] The bowl portion 12 of the urinal cover 1 has a concavely curved surface. In other words, the surface of the bowl portion 12 is a concavely curved bowl surface. The surface of the bowl portion 12 includes a receiving surface 121 that is long in the vertical direction, and a bottom surface 125 that connects to the lower end of the receiving surface 121. The receiving surface 121 is formed as a concavely curved surface that is recessed backward. The bottom surface 125 is formed as a concavely curved surface that is recessed downward.

[0022] When the urinal cover 1 is attached so as to cover the existing urinal 9, the receiving surface 121 of the urinal cover 1 is positioned at a distance in front of the receiving surface 921 of the existing urinal 9 so as to cover and conceal the receiving surface 921. In one embodiment, the front-to-rear distance between the upper half of the receiving surface 121 of the urinal cover 1 and the upper half of the receiving surface 921 of the existing urinal 9 is set to be greater than the front-to-rear distance between the lower half of the receiving surface 121 of the urinal cover 1 and the lower half of the receiving surface 921 of the existing urinal 9.

[0023] When the urinal cover 1 is attached to cover the existing urinal 9, the bottom surface 125 of the urinal cover 1 is positioned above and spaced apart from the bottom surface 925 of the existing urinal 9 so as to cover and conceal the bottom surface 925.

[0024] The left and right side walls 14 of the urinal cover 1 are positioned at a distance from each other in the left-right direction. The left and right side walls 14 form the left and right side end portions of the urinal cover 1. In one embodiment, the left and right side walls 14 each have an arc-shaped curve that bulges outward in a plan view.

[0025] The upper wall 16 of the urinal cover 1 is located above the bowl portion 12. The upper wall 16 forms the upper end of the urinal cover 1. In one embodiment, the upper wall 16 has a bow-shaped outer shape in a plan view. The upper wall 16 has a peripheral portion that bulges out in an arc shape toward the rear, and an upright piece 165 protrudes upward from this peripheral portion. The upright piece 165 has an arc-shaped curved shape in a plan view so as to smoothly connect the left and right side walls 14.

[0026] The drainage holes 18 of the urinal cover 1 are formed in the bottom surface 125 of the bowl portion 12. The urinal cover 1 is configured so that urine and flushing water that hits the receiving surface 121 of the bowl portion 12 and flows down are collected on the bottom surface 125 and then discharged through the drainage holes 18.

[0027] (Renovation method) As shown in Figure 3, in one embodiment of the renovation method, a urinal cover 1 made of synthetic resin is attached so as to completely cover an existing urinal 9 that has been previously fixed to a wall W1. The urinal cover 1 is, for example, a wall-mounted type and is installed by being fixed to the wall W1, but the urinal cover 1 may also be a floor-standing type. In one embodiment of the renovation method, the existing water supply pipe 4 and drainage pipe 5 that were used for the existing urinal 9 are still used after the renovation.

[0028] When the urinal cover 1 is attached so as to cover the existing urinal 9, the bowl portion 12 of the urinal cover 1 covers the existing bowl portion 92 of the existing urinal 9 from the front. In this case, the drain hole 18 provided in the bowl portion 12 of the urinal cover 1 is preferably located above the existing drain hole 98 of the existing urinal 9. The drain hole 18 of the urinal cover 1 may be located directly above the existing drain hole 98, or may be located diagonally above in front of or above in rear of the existing drain hole 98.

[0029] Similarly, when the urinal cover 1 is attached to cover the existing urinal 9, the left and right side walls 14 of the urinal cover 1 cover and conceal the left and right existing side walls 94 of the existing urinal 9 from the left and right outer sides, respectively. When the urinal cover 1 is attached to cover the existing urinal 9, the top wall 16 of the urinal cover 1 covers and conceals the top wall 96 of the existing urinal 9 from above.

[0030] In one embodiment of the renovation method, a urinal cover 1 is attached to cover the existing urinal 9, and the renovation is performed so that drainage occurs through the drainage hole 18 of the urinal cover 1 and the existing drainage hole 98 of the existing urinal 9.

[0031] Specifically, the drain pipe 2 prepared for the renovation is connected to the drain hole 18 of the urinal cover 1. The drain pipe 2 is, for example, a pipe made of synthetic resin. The drain pipe 2 connected to the drain hole 18 can be pulled downward by passing it through the existing drain hole 98 of the existing urinal 9, and then connected to the existing drain piping 5 provided in the wall W1.

[0032] As shown in Figure 3, the upstream end 21 of the drain pipe 2 connected to the drain hole 18 of the urinal cover 1 is located in the gap formed between the bowl portion 12 of the urinal cover 1 and the existing bowl portion 92 of the existing urinal 9 located below it. The drain pipe 2 has a trap portion 25 that is bent in a U-shape. The trap portion 25 of the drain pipe 2 is located inside the existing urinal 9.

[0033] When the urinal cover 1 is attached to cover the existing urinal 9, a space S1 for storing equipment is formed between the upper wall 16 of the urinal cover 1 and the existing upper wall 96 of the existing urinal 9 located below it. Equipment 7 can be stored in the space S1.

[0034] The device 7 is, for example, a housing that houses a circuit board and an electromagnetic valve, and has the function of supplying water supplied through a water supply pipe 4 installed on the wall W1 to the bowl portion 12, and the function of controlling the supply of water to the bowl portion 12 based on the detection results of a human body.

[0035] The device 7 can be placed, for example, on the existing upper wall 96 of the existing urinal 9 via an appropriate structure such as an installation board, or directly. A water supply pipe 31 is connected between the device 7 and the existing water supply pipe 4 provided in the wall W1. Water supplied through the water supply pipe 4 is supplied to the device 7 via the water supply pipe 31.

[0036] A water supply pipe 32 is connected between the device 7 and the water outlet 17 installed at the upper end of the bowl part 12 of the urinal cover 1. Water supplied to the device 7 through the water supply piping 4 is supplied to the water outlet 17 via the water supply pipe 32.

[0037] Water discharger 17 has the function of diffusing and discharging water onto the upper end of receiving surface 121 of bowl portion 12. The water discharged from water discharger 17 onto receiving surface 121 flows down along receiving surface 121 as cleaning water, is collected on bottom surface 125, and then is discharged through drainage hole 18.

[0038] (Action and effect) According to the renovation method of one embodiment, there is no need to dismantle and remove the existing urinal 9 as in the conventional technology described above, and it is instead possible to renovate the urinal by effectively utilizing the existing urinal 9. Therefore, according to the renovation method of one embodiment, it is possible to make effective use of resources, and further to improve the efficiency of the renovation work and reduce the cost of the renovation work.

[0039] 2. Variations The above embodiment is merely one of various embodiments of the present disclosure, and various modifications can be made to the above embodiment.

[0040] Modifications of the above embodiment will be described below. In the description of the modifications, the same components as those described in the above embodiment will be assigned the same reference numerals and detailed description will be omitted. The various modifications listed below can be applied in appropriate combination.

[0041] In the above embodiment, the urinal cover 1 is configured to cover the entire existing urinal 9 when attached, but this is not limited to this, and the urinal cover 1 may be configured to cover at least the existing bowl portion 92 of the existing urinal 9 when attached, and to expose another part of the existing urinal 9. For example, the urinal cover 1 may be configured so that when attached, parts of the existing left and right side walls 94 of the existing urinal 9 are exposed to the sides.

[0042] In the above embodiment, the urinal cover 1 is configured from a single resin molded product that is molded as a whole, but the form of the urinal cover 1 is not limited to this. For example, the urinal cover 1 may be configured by combining multiple resin molded products, or the urinal cover 1 may be configured by combining one or more resin molded products with one or more metal parts.

[0043] In the above embodiment, the device 7, which has the function of supplying water from the water supply pipe 4 toward the bowl portion 12, is placed between the upper wall 16 of the urinal cover 1 and the existing upper wall 96 of the existing urinal 9, but the location of the device 7 is not limited to this. The device 7 can also be placed in another space formed between the urinal cover 1 and the existing urinal 9, or it can be placed inside the existing urinal 9.

[0044] In the above embodiment, the top wall 16 of the urinal cover 1 is molded integrally with the bowl portion 12 and the left and right side walls 14. However, at least a portion of the top wall 16 may be molded separately from the bowl portion 12 and the left and right side walls 14. In this case, it is also preferable that at least a portion of the top wall 16 of the urinal cover 1 is configured to be detachable from other portions of the urinal cover 1. In other words, it is also preferable that at least a portion of the top wall 16 of the urinal cover 1 is configured as a detachable lid. According to this modification, by removing the portion of the top wall 16 that forms the lid, an opening that communicates with the space S1 is formed, and it is possible to install a device 7 in the space S1 through this opening or to inspect the device 7 through this opening. It is also preferable that at least a portion of the top wall 16 of the urinal cover 1 is configured to be openable and closable from other portions of the urinal cover 1. In other words, it is also preferable that at least a portion of the top wall 16 of the urinal cover 1 is configured as a lid that can be opened and closed, for example, by rotating or sliding. According to this modification, by opening the portion of the upper wall 16 that constitutes the lid, an opening that communicates with the space S1 is formed, and it is possible to install the device 7 in the space S1 through this opening, and to inspect the device 7 through this opening. The portion of the upper wall 16 that constitutes the lid is preferably located above the space S1. In other words, the portion of the upper wall 16 that constitutes the lid is preferably located above the device 7 that will be installed in the space S1, and is also preferably located above the existing upper wall 96 of the existing urinal 9.

[0045] In the above embodiment, with the urinal cover 1 attached so as to cover the existing urinal 9, drainage occurs through the drain hole 18 of the urinal cover 1 and the existing drain hole 98 of the existing urinal 9, but drainage may also occur without passing through the existing drain hole 98 of the existing urinal 9. Specifically, rather than pulling the drain pipe 2 connected to the drain hole 18 of the urinal cover 1 into the existing urinal 9 through the existing drain hole 98, it is possible, for example, to route the drain pipe 2 rearward through the gap formed between the urinal cover 1 and the existing urinal 9 (particularly the gap formed below the existing urinal 9) and connect it to the existing drainage piping 5 in the wall W1.
