Summary of the Invention

Problems to be Solved by the Invention

[0004] However, when the cover component is integrally formed with the shower pipe, there is a risk that the cover component may interfere with the wall-side fixture with downward displacement when the shower pipe is inserted into another flow path member. On the other hand, if the cover component is made to have a shape that is one size larger so as not to interfere with the wall-side fixture, it becomes difficult to ensure the contact surfaces between them, and fastening with screws becomes difficult. Therefore, the present invention provides a pipe fixing structure for a faucet that can appropriately fix the pipe material to the wall surface.

Means for Solving the Problems

[0005] To solve the above problems, the pipe fixing structure for a faucet of the present invention takes the following means.

[0006] In other words, the first invention of the present invention is a pipe fixing structure for a faucet that fixes a pipe material extending in the vertical direction to a wall surface, comprising: a wall-side fixing device fixed to the wall surface; and a connecting device that is directly or indirectly connected to the pipe material and is placed over the wall-side fixing device so as to cover its periphery and fastened by screws inserted from above, wherein the connecting device comprises a top plate that is placed over the wall-side fixing device so as to be pressed against it from above, and a bottom plate that is placed over the wall-side fixing device so as to form a gap that separates it downwards, and the wall-side fixing device has a screw hole in the top plate through which the screws passed from above can be fastened.

[0007] According to the first invention, even if the connector is displaced downward and placed over the wall-side fixing device as the pipe material is inserted into another flow channel member, the gap between the bottom plate and the wall-side fixing device prevents interference between them. Furthermore, since the top plate through which screws are passed from above is pressed against the wall-side fixing device having screw holes from above, the contact surface when fastening with screws can be properly secured. Therefore, the pipe material can be properly fixed to the wall surface using the connector.

[0008] The second invention of the present invention is a faucet pipe fixing structure in which, in the first invention described above, the wall-side fixing device has a guide that recesses the area around the opening of the screw hole in a conical shape toward the screw hole so that the tip of the screw is guided toward the wall surface together with the connector when inserted from above.

[0009] According to the second invention, by tightening the screws, the connector that surrounds the wall-side fastener can be fastened to the wall-side fastener while being brought closer to the wall surface. Furthermore, a guide for the screws in this way can be easily formed simply by machining a conical recess around the screw hole of the wall-side fastener.

[0010] The third invention of the present invention is a faucet pipe fixing structure in which, in the first or second invention described above, the connector is placed over the wall-side fixing device while being displaced downward as the lower end of the pipe material is inserted from above into another flow path member, or is pulled away from the wall-side fixing device while being displaced upward as it is removed from the flow path connection with the other flow path member.

[0011] According to the third invention, the coupling device attached to the pipe material can be easily attached to or detached from the wall-side fixing device. Therefore, maintenance such as fixing the pipe material to the wall surface or removing it from the wall surface can be easily performed. [Brief explanation of the drawing]

[0013] Hereinafter, embodiments for implementing the present invention will be described with reference to the drawings.

[0014] <<First Embodiment>> (Schematic Configuration of the Pipe Fixing Structure 1 for a Faucet) First, the configuration of the pipe fixing structure 1 for a faucet according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 12. In the following description, when indicating directions such as front, back, top, bottom, left, and right, the respective directions shown in each figure shall be referred to. The directions shown in each figure are the directions as seen from a user standing facing the wall surface W of the bathroom where the pipe fixing structure 1 for a faucet is provided.

[0015] As shown in FIG. 1, the pipe fixing structure 1 for a faucet according to the present embodiment is a structure for fixing the shower pipe SP to the wall surface W of the bathroom. The shower pipe SP is disposed so as to extend vertically along the wall surface W of the bathroom. Here, the shower pipe SP corresponds to the "pipe material" of the present invention.

[0016] The shower pipe SP is configured as a flow path member for spraying the hot and cold water supplied from the mixing faucet F (see FIG. 12) connected to the lower end portion thereof from an overhead shower (not shown) connected to the upper end portion. Specifically, the shower pipe SP is configured to be divided into a circular tubular upper pipe P1 connected to the overhead shower (not shown) and a circular tubular lower pipe P2 connected to the above-described mixing faucet F (see FIG. 12).

[0017] The connection portion between the upper pipe P1 and the lower pipe P2 of the shower pipe SP is fixed to the wall surface W by the pipe fixing structure 1 for a faucet. Although the shower pipe SP is also fixed to the wall surface W at locations other than the above, detailed description thereof is omitted.

[0018] The faucet pipe fixing structure 1 is configured to also function as a connecting member that connects the upper pipe P1 and the lower pipe P2 to each other in a flow path. The upper pipe P1 and the lower pipe P2 are connected via the faucet pipe fixing structure 1 so as to abut each other in the pipe axis direction (up and down direction).

[0019] As a result, the upper pipe P1 and the lower pipe P2 are configured such that only one seam (joint) is exposed between them. As shown in Figure 2, the faucet pipe fixing structure 1 is fixed inside the upper pipe P1 and the lower pipe P2, and is configured to protrude from an opening Pc formed in the rear peripheral wall of the upper pipe P1 and be fixed to the bathroom wall W.

[0020] The opening Pc of the upper pipe P1 is formed in the inner peripheral wall, which is not visible from the front of the upper pipe P1. Furthermore, as shown in Figure 3, the faucet pipe fixing structure 1 is shaped to fit within the width of the upper pipe P1 and is configured so that it is not visible from the front of the upper pipe P1. As a result, the faucet pipe fixing structure 1 does not expose any seams (joints) as a fixing structure on the front side of the upper pipe P1 or lower pipe P2 as shown in the figure.

[0021] (Composition of each part) The configuration of each part of the faucet pipe fixing structure 1 will be described in detail below. As shown in Figure 4, the faucet pipe fixing structure 1 includes a pipe support 2 that is connected to the upper pipe P1, a wall-side fixing 3 that is fixed to the wall surface W, and a connecting 4 that connects these together to form an integrated unit.

[0022] As shown in Figures 4 and 5, the pipe support 2 has a cylindrical portion 2A that extends in the pipe axis direction (vertical direction) and a protruding portion 2B that extends in a rectangular prism shape from the peripheral wall on the inner side of the cylindrical portion 2A shown in the figure. The pipe support 2 also has a connector 2C that extends in the pipe axis direction and is connected to the flow path of the cylindrical portion 2A from below by screwing it in.

[0023] The cylindrical portion 2A is formed in a cylindrical shape that can be inserted from below into the connection port Pa at the lower end of the upper pipe P1. As shown in Figure 5, the protruding portion 2B is formed in a rectangular prism shape that can be inserted from below into the opening Pc formed in the inner peripheral wall of the upper pipe P1.

[0024] The opening Pc formed in the upper pipe P1 is designed to open continuously from the connection port Pa. More specifically, the opening Pc is formed in a square shape such that when the upper pipe P1 is viewed from the rear, its shape matches the square prism shape of the protruding portion 2B.

[0025] As shown in Figures 6 and 7, the cylindrical portion 2A is inserted from below into the connection port Pa at the lower end of the upper pipe P1, thereby setting it in a state where it is fitted to the inner surface of the upper pipe P1. The protruding portion 2B is inserted from below into the opening Pc in conjunction with the insertion of the cylindrical portion 2A, thereby setting it in a state where it is fitted to the opening Pc.

[0026] Specifically, the protruding portion 2B is inserted into the opening Pc until it abuts against its upper edge. As a result, the protruding portion 2B is fitted in contact with the upper edge of the opening Pc and each side edge in the circumferential direction of the pipe. This positions the cylindrical portion 2A in the diameter direction by fitting it to the upper pipe P1, and also positions it in the axial direction (upward) and circumferential direction by fitting the protruding portion 2B to the opening Pc.

[0027] The cylindrical portion 2A is set so that its cylindrical part fits snugly inside the upper pipe P1 by the above positioning. As shown in Figure 7, the protruding portion 2B is configured to protrude inward from a position slightly above the lower edge of the cylindrical portion 2A. As a result, even if the upper pipe P1 and the lower pipe P2 are connected in a flow path so that they abut each other vertically as shown in Figure 2, the protruding portion 2B does not interfere with the lower pipe P2.

[0028] As shown in Figures 6 and 7, the cylindrical portion 2A and the protruding portion 2B are set on the upper pipe P1 as described above, and then brazed to the upper pipe P1 (welded portion B). Specifically, the upper edge and each of the three sides of the fitting portion between the protruding portion 2B and the opening Pc of the upper pipe P1 are brazed (welded portion B).

[0029] Furthermore, the outer surface of the cylindrical portion 2A is brazed to the inner surface of the upper pipe P1 (welded portion B). Specifically, as shown in Figure 5, an annular groove Aa is formed on the outer surface of the cylindrical portion 2A at a position slightly below its upper edge. The cylindrical portion 2A is fitted into the upper pipe P1 with a ring-shaped brazing material pre-set in this annular groove Aa.

[0030] Then, as shown in Figures 6 and 7, after setting the cylindrical part 2A on the upper pipe P1, the upper pipe P1 is heated from the outside, causing the brazing material to melt and flow into the gap between it and the upper pipe P1. The subsequent cooling then joins the two parts together. As a result, a ring braze Br is formed between the cylindrical part 2A and the upper pipe P1, brazing them together in a ring shape.

[0031] As shown in Figures 4 and 5, the connector 2C is formed in a stepped cylindrical shape that can be inserted from above into the connection port Pb at the upper end of the lower pipe P2. As shown in Figures 6 and 7, the connector 2C is set in a state where it is fitted to the inner circumferential surface of the lower pipe P2 by inserting the larger diameter portion of the cylinder at the lower end of the lower pipe P2 into the connection port Pb at the upper end of the lower pipe P2 from above.

[0032] Specifically, as shown in Figure 7, the connector 2C is inserted into the connection port Pb of the lower pipe P2 until it abuts against the stepped portion Pd where the inner diameter of the lower pipe P2 is reduced. As a result, the connector 2C is positioned in the cylindrical direction by fitting with the lower pipe P2, and also in the pipe axis direction (downward) by abutting against the stepped portion Pd.

[0033] As a result of the above positioning, the connector 2C is set so that the larger diameter portion of its lower cylinder fits snugly inside the lower pipe P2, while the smaller diameter portion of its upper cylinder protrudes from the upper end of the lower pipe P2. After the connector 2C is set in the lower pipe P2, it is brazed to the lower pipe P2 (welded portion B). Specifically, the outer surface of the connector 2C is brazed to the inner surface of the lower pipe P2 (welded portion B).

[0034] More specifically, as shown in Figure 5, an annular groove Ca is formed on the outer surface of the connector 2C, slightly above its lower edge. The connector 2C is fitted into the lower pipe P2 with a ring-shaped brazing material pre-set in this annular groove Ca.

[0035] Then, as shown in Figures 6 and 7, after setting the connector 2C on the lower pipe P2, the lower pipe P2 is heated from the outside, causing the brazing material to melt and flow into the gap between the connector and the lower pipe P2. The subsequent cooling then joins the two. As a result, a ring braze Br is formed between the connector 2C and the lower pipe P2, brazing them together in a ring shape.

[0036] After the connector 2C is fixed to the lower pipe P2 as described above, the small diameter portion of the cylindrical part that protrudes upward is screwed from below into the cylindrical part 2A fixed to the upper pipe P1 to connect to the flow path. An annular recessed mounting groove Cb is formed on the outer surface of the small diameter portion of the connector 2C that is screwed into the cylindrical part 2A.

[0037] An O-ring (not shown) is fitted into this mounting groove Cb, and the space between them is sealed when the connector 2C is screwed into the cylinder of the cylindrical part 2A (see Figure 2). Screwing the connector 2C into the cylindrical part 2A can be easily done by screwing the lower pipe P2, which is integrated with the connector 2C, into the upper pipe P1, which is integrated with the cylindrical part 2A.

[0038] Through the above screwing process, the connector 2C is connected to the cylindrical portion 2A in a state where the insides of both cylinders are in communication. These connectors 2C and cylindrical portion 2A function as flow path members that form the internal flow paths of the lower pipe P2 and the upper pipe P1.

[0039] Furthermore, the connector 2C is sealed by being brazed around its entire circumference to the lower pipe P2 using a ring rod Br. The cylindrical portion 2A is also sealed by being brazed around its entire circumference to the upper pipe P1 using a ring rod Br.

[0040] As shown in Figures 4 and 6, the connector 4 consists of a rectangular cylindrical member extending in the front-rear direction. The connector 4 has a connecting portion 4A at the front end of the cylinder shown, which is connected to an overhang 2B that extends from the upper pipe P1 toward the rear. As shown in Figures 8 and 9, the connecting portion 4A is fitted to the overhang 2B so as to surround it from the rear side shown.

[0041] Then, as shown in Figure 9, the connector 4 is fixed to the protruding part 2B by inserting two first screws T1, one above and one below, from the rear side shown in the figure into the corresponding through holes 4C and fastening them to the screw holes B1 of the protruding part 2B. After the above connection, as shown in Figures 10 to 11, the connector 4 is placed over the wall-side fixing device 3, which is fixed to the wall surface W, from the front side shown in the figure, and fixed by inserting and fastening the second screws T2 from above.

[0042] The connector 4 has a cylindrical end on the rear side of the diagram which is fitted over the wall-side fixing device 3 from the front side of the diagram, forming a cover portion 4B. After the cover portion 4B is fitted over the wall-side fixing device 3, the second screw T2 is inserted from above and fastened, causing it to be pulled closer to the wall surface W and fixed in a gap-free state.

[0043] Specifically, as shown in Figure 11, the connector 4 is moved toward the wall surface W as the second screw T2 is inserted, and the second screw T2 is pressed from above against the inclined surface of the conical recessed guide 3D formed in the wall-side fixing device 3, guiding it toward the wall surface W. As a result, the connector 4 is fixed between itself and the wall surface W without any gaps. Here, the second screw T2 corresponds to the "screw" of the present invention.

[0044] As shown in Figure 10, the wall-side fixing device 3 has a flat base 3A that is placed against the wall surface W, and a flat projection plate 3B that extends from the upper and lower middle part of the base 3A toward the front in the figure. The wall-side fixing device 3 is fixed to the wall surface W by placing the base 3A against the wall surface W, and then inserting two third screws T3 from the front in the figure into the base 3A and fastening them.

[0045] As described above, the connecting member 4 is fixed to the wall surface W by being placed over the wall-side fixing member 3 from the front side as shown in the diagram, and then positioned close to the wall surface W. First, the rear covering portion 4B of the connecting member 4 is placed over the wall-side fixing member 3 from the front side as shown in the diagram, surrounding it. Next, the second screw T2 is inserted from above into the through hole 4D formed in the center of the top plate 4F of the covering portion 4B.

[0046] As a result, as shown in Figure 11, the inserted end of the second screw T2 is pressed against the inclined surface on the front side of the guide 3D, which is recessed in a conical hole shape formed on the upper surface of the protruding plate 3B of the wall-side fixing device 3. Consequently, as the second screw T2 is inserted, it is guided along the inclined surface of the guide 3D toward the rear wall surface W shown in the figure.

[0047] The second screw T2 is guided into the screw hole 3C formed in the center of the conical recess of the guide 3D by being inserted into the conical recess of the guide 3D. Therefore, by inserting and screwing in the second screw T2, it can be screwed into the screw hole 3C and fastened. This allows the connector 4 to be brought closer to the wall surface W and fixed in place.

[0048] As the second screw T2 is fastened, the top plate 4F of the cover portion 4B of the connector 4 is pressed against the upper surface of the base 3A by the head of the second screw T2. As a result, the connector 4 is fixed in place so that the top plate 4F is sandwiched between the head of the second screw T2 and the wall-side fixing device 3.

[0049] When the connector 4 is fastened to the wall-side fixing device 3 by the second screw T2, the top plate 4F of the cover portion 4B is pressed against the upper surface of the base 3A, and the bottom plate 4E of the cover portion 4B is placed over the lower surface of the base 3A with a gap T in the height direction. The connector 4 is designed so that such a gap T is formed when it is fastened to the wall-side fixing device 3, making it easy to attach and detach from the wall-side fixing device 3 even though it is an integral part of the shower pipe SP.

[0050] Specifically, as shown in Figure 12, the connector 4 is fastened to the wall-side fixing device 3 by being placed over it, starting from a state where it is integrally connected with the shower pipe SP. First, the shower pipe SP is tilted slightly towards the front, and its lower end is inserted from above into the connecting pipe section F1 that protrudes from the upper surface of the mixing faucet F to connect the flow path. Here, the connecting pipe section F1 corresponds to the "other flow path member" of the present invention.

[0051] Then, as the shower pipe SP is inserted, the connector 4 is gradually raised inward while the connector 4 is placed over the wall-side fixing device 3. As a result, the connector 4 is placed over the wall-side fixing device 3 with a downward displacement. At this time, the connector 4 has a configuration with the gap T described above in Figure 11, which allows the bottom plate 4E to slide under the base 3A of the wall-side fixing device 3 without interfering with the base 3A.

[0052] Furthermore, as shown in Figure 12, the connector 4 is designed to be easily removed from the wall-side fixing device 3 without interfering with it. Specifically, first, the shower pipe SP is tilted towards the front and pulled upward to disconnect it from the flow path connection of the connecting pipe F1 of the mixing faucet F. Then, in conjunction with this pulling, the connector 4 is detached from the wall-side fixing device 3 towards the front.

[0053] As a result, the connector 4 is removed from the wall-side fixing device 3 with an upward displacement. At this time, because the connector 4 has the gap T described above in Figure 11 relative to the wall-side fixing device 3, the bottom plate 4E can be pulled out towards the front of the base 3A of the wall-side fixing device 3 without interfering with the base 3A.

[0054] The connector 4 is fastened by screwing the second screw T2 into the screw hole 3C formed in the wall-side fixing device 3, thereby fixing it in a manner that prevents slippage relative to the wall-side fixing device 3. Therefore, the connector 4 can be properly fixed to the wall-side fixing device 3.

[0055] In summary, the faucet pipe fixing structure 1 according to the first embodiment has the following configuration. The reference numerals in parentheses below correspond to the respective components shown in the above embodiment.

[0056] In other words, the faucet pipe fixing structure (1) for fixing a vertically extending pipe material (SP) to a wall surface (W) comprises a wall-side fixing device (3) fixed to the wall surface (W), and a connecting device (4) that is directly or indirectly connected to the pipe material (SP) and is placed over the wall-side fixing device (3) so as to cover its periphery and fastened by screws (T2) inserted from above. The connecting device (4) comprises a top plate (4F) that is placed over the wall-side fixing device (3) so as to be pressed against it from above, and a bottom plate (4E) that is placed over the wall-side fixing device (3) so as to form a gap (T) that separates it downwards. The wall-side fixing device (3) has a screw hole (3C) through which screws (T2) passed from above can be fastened in the top plate (4F).

[0057] With the above configuration, even if the connector (4) is displaced downward and placed over the wall-side fixing device (3) as the pipe material (SP) is inserted into another flow path member (F1), the gap (T) between the bottom plate (4E) and the wall-side fixing device (3) prevents them from interfering with each other. Furthermore, the top plate (4F), through which the screws (T2) are passed from above, is brought into contact with the wall-side fixing device (3) which has screw holes (3C) from above, thereby ensuring a proper contact surface when fastening with the screws (T2). Therefore, the pipe material (SP) can be properly fixed to the wall surface (W) using the connector (4).

[0058] Furthermore, the wall-side fixing device (3) has a guide (3D) that recesses the area around the opening of the screw hole (3C) toward the screw hole (3C) so that the tip of the screw (T2) is guided toward the wall surface (W) together with the connector (4) as it is inserted from above. With the above configuration, the connector (4) that surrounds the wall-side fixing device (3) can be fastened to the wall-side fixing device (3) while being brought toward the wall surface (W) by tightening the screw (T2). Moreover, the guide (3D) that guides the screw (T2) in this way can be easily formed by simply machining a conical recess around the screw hole (3C) of the wall-side fixing device (3).

[0059] Furthermore, the connector (4) is displaced downward and placed over the wall-side fixing device (3) when the lower end of the pipe material (SP) is inserted from above into another flow channel member (F1), and displaced upward and pulled away from the wall-side fixing device (3) when it is removed from the flow channel connection with the other flow channel member (F1). With the above configuration, the work of placing the connector (4) connected to the pipe material (SP) over the wall-side fixing device (3) and pulling it away can be easily performed. Therefore, maintenance such as fixing the pipe material (SP) to the wall surface (W) and removing it from the wall surface (W) can be easily performed.

[0060] Regarding other embodiments: Although an embodiment of the present invention has been described above using one embodiment, the present invention can be implemented in various forms as shown below, in addition to the above embodiment.

[0061] 1. The pipe fixing structure for faucets of the present invention may be configured such that the connector is directly joined to the pipe material by welding or the like, without the need for a pipe support.

[0062] 2. The wall-side fixing device may not have a configuration that includes a guide to direct the connector toward the wall surface by fastening screws. If a guide is formed on the wall-side fixing device, the guide may consist of a conical hole that creates a conical recess for the contact surface with the screw, or it may consist of an inclined surface that tilts the contact surface with the screw toward the wall surface.

[0063] 3. The pipe material fixed by the faucet pipe fixing structure may be cylindrical or rectangular. In addition, the pipe material may be a shower pipe or a slide bar that allows the mounting position of the shower hook on the wall to be changed in the height direction.

[0064] The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of the present invention is indicated by the claims rather than by the description of the embodiments above, and all modifications within the meaning and scope equivalent to the claims are intended to be included.
