Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when attaching the housing member 90 to the body 80 of the faucet 70 in Patent Document 1, since it is necessary to screw three screws 71 into the screw holes 91a of the housing member 90, the attachment work is complicated.

Means for Solving the Problems

[0005] The faucet in embodiment 1 comprises a cylindrical body and a bottomed cylindrical joint inserted into the body, wherein the body and the joint have retaining parts that prevent them from coming loose by engaging with each other.

[0006] With this configuration, the joint can be attached to the body in a secured state by engaging the body's retaining portion with the joint's retaining portion. Since the joint can be secured without using screws, the process of attaching the joint to the body can be simplified.

[0007] Embodiment 2 further includes a rotation-retaining member that restricts the relative rotation of the body and the joint, in addition to the faucet of Embodiment 1. With this configuration, the rotation-retaining member can restrict the relative rotation of the body and the joint.

[0008] Embodiment 3 is a faucet according to Embodiment 1 or Embodiment 2, wherein the body has ribs protruding radially inward, and the joint has a flange protruding radially outward, and the ribs and flange function as the retaining part. With this configuration, the joint can be prevented from coming off the body by engaging the ribs of the body with the flange of the joint.

[0009] Embodiment 4 is the faucet described in Embodiment 3, wherein the body has multiple ribs and the joint has multiple flanges. With this configuration, the joint can be prevented from coming loose at multiple locations using the multiple ribs and multiple flanges. Therefore, the joint can be prevented from coming loose from the body in a more stable manner.

[0010] Embodiment 5 is a faucet according to Embodiment 3 or Embodiment 4, wherein the flange has an outer circumference that follows a circular shape and a notch in which a part of the circular shape is cut out in an arc shape, and the rib has the same shape as the arc shape. With this configuration, when the flange of the joint and the rib of the body engage with each other, the area of ​​engagement can be made relatively larger. Therefore, the joint can be prevented from coming off the body in a more stable state.

[0011] Embodiment 6 is a faucet according to any one of Embodiments 1 to 5, further comprising a cover that houses the body and the joint. With this configuration, the joint can be easily attached to the body in a faucet that has a cover. [Effects of the Invention]

[0012] According to the faucet of the present invention, the installation work of the joint to the body can be simplified. [Brief explanation of the drawing]

Best Mode for Carrying Out the Invention

[0014] An embodiment of the faucet will be described. As shown in FIGS. 1 and 2, the faucet 10 is installed on a wall portion 11 which is a counter of a kitchen cabinet. The faucet 10 includes a faucet body 12 fixed to the wall portion 11, a lever 13 attached to the upper part of the faucet body 12, a water discharge head 19 protruding obliquely upward from the central portion in the axial direction of the faucet body 12, and a cylindrical cover 15 attached to the faucet body 12 from the axial side. Further, the faucet 10 includes a water supply pipe 16, a hot water supply pipe 17, and a water discharge pipe 18 connected to the faucet body 12.

[0015] As shown in FIG. 2, an opening (not shown) penetrating the cover 15 is provided at the central portion in the axial direction of the cover 15. A peripheral wall 15a extending obliquely upward of the cover 15 is provided at a position surrounding the opening. The water discharge head 19 is attached to the tip of the peripheral wall 15a. A hose for water discharge (not shown) is connected to the water discharge head 19. This hose is inserted through the opening of the cover 15 and extends below the wall portion 11, and then is connected to the water discharge pipe 18.

[0016] Each member constituting the faucet body 12 will be described. As shown in FIG. 2, the faucet body 12 has a cylindrical body 20, a bottomed cylindrical joint 30 connected to the upper part of the body 20, and a valve member 40 housed in the joint 30. Further, the faucet body 12 has a fixing nut 50 connected to the joint 30 in a state of abutting against the upper part on the outer peripheral side of the valve member 40, and a stopper member 60 attached to the outer periphery of the body 20 and defining the rotation range of the cover 15 with respect to the body 20. By connecting the fixing nut 50 to the joint 30, the valve member 40 is fixed in a state of being housed in the joint 30. Therefore, the joint 30 is also referred to as a housing member.

[0017] As shown in Fig. 2, since the body 20 is configured in a cylindrical shape, it has openings 20a at both ends on one end side and the other end side in the axial direction. Further, the body 20 also has an opening (hereinafter, also referred to as a side opening 20b) on the side surface of the central portion in the axial direction. The body has a groove 21 extending in the circumferential direction on the other end side with respect to the side opening 20b. This groove 21 extends from the back side of the body 20, which is the rear side toward the faucet 10, along the circumferential direction of the body 20 from both the left and right sides to the front side. On the front side of the body 20, the tips of the grooves 21 extending from both the left and right sides are not connected to each other. That is, the tips of the grooves 21 extending from both the left and right sides are spaced apart from each other. A stopper member 60 is attached to this groove 21. Details of the stopper member 60 will be described later.

[0018] As shown in Fig. 2, the body 20 has an insertion hole 22 through which the threaded portion of the screw 25 is inserted at a position on the front side of the body 20 and on one end side with respect to the side opening 20b. By screwing the screw 25 inserted through this insertion hole 22 into the screw hole 34a of the joint 30 described later, relative rotation of the joint 30 with respect to the body 20 can be suppressed.

[0019] Further, the body 20 has a thread groove 23 on the outer periphery of the end portion on the other end side. By attaching a fixing member (not shown) to this thread groove 23, the body 20 is fixed to the wall portion 11.

[0020] Inside the body 20, a water supply pipe 16, a hot water supply pipe 17, and a drain pipe 18 are inserted. The water supply pipe 16, the hot water supply pipe 17, and the drain pipe 18 are connected to the through holes 33 (see Fig. 4) in the bottom wall 31 of the joint 30, respectively, and thus communicate with the valve member 40. Since the water supply pipe 16 is connected to a water supply source (not shown), it supplies the water supplied from the water supply source to the valve member 40. Since the hot water supply pipe 17 is connected to a hot water supply source (not shown), it supplies the hot water supplied from the hot water supply source to the valve member 40. In the valve member 40, the water supplied from the water supply source and the hot water supplied from the hot water supply source are mixed to form hot water. Therefore, it can be said that the valve member 40 is a hot water mixing valve.

[0021] The discharge pipe 18 is connected to a hose that passes through the inside of the body 20 from a side opening 20b of the body 20. The discharge pipe 18 supplies hot water formed by the valve member 40 to the discharge head 19 via the hose. The body 20 functions as a case through which the water supply pipe 16, hot water supply pipe 17, discharge pipe 18, and hose are inserted.

[0022] As shown in Figure 2, an operating shaft 41 for operating the valve member 40 is provided at the top of the valve member 40. A lever 13 is connected to this operating shaft 41. By operating the lever 13, the valve member 40 can be operated. By operating the valve member 40, it is possible to stop the flow of water from the faucet 10, switch between hot and cold water, and adjust the mixing of hot and cold water.

[0023] <Joint details> As shown in Figures 3 and 4, the joint 30 is configured as a bottomed cylindrical shape. The joint 30 has a circular bottom wall 31 and a cylindrical peripheral wall 32 extending from the outer circumference of the bottom wall 31 in the thickness direction of the bottom wall 31. The joint 30 has a screw groove 32a on the inner circumference of the peripheral wall 32. The joint 30 and the fixing nut 50 are connected when the screw groove 51 (see Figure 2) of the fixing nut 50 is screwed into this screw groove 32a.

[0024] The joint 30 has three through holes 33 in its bottom wall 31. The water supply pipe 16, the hot water supply pipe 17, and the discharge pipe 18 are connected to these through holes 33. The through hole 33a, to which the water supply pipe 16 and the hot water supply pipe 17 are connected, has the same inner diameter. The through hole 33b, to which the discharge pipe 18 is connected, has a slightly larger inner diameter than the other two through holes 33a.

[0025] The joint 30 has a recess 32b formed around its entire circumference on the outer circumference of the bottom wall 31 side, which is the other end of the peripheral wall 32 in the axial direction. A packing and a slip plate (not shown) are placed in this recess 32b. By placing the packing and slip plate in the recess 32b, when the cover 15 is attached to the faucet body 12, a seal can be created between the inner circumference of the cover 15 and the outer circumference of the joint 30, which is the faucet body 12.

[0026] As shown in Figures 3 and 4, the joint 30 has a columnar small-diameter portion 34 that extends in the thickness direction of the bottom wall 31 from the side of the bottom wall 31 opposite to the side on which the peripheral wall 32 extends (hereinafter also referred to as the other end face 31a). The small-diameter portion 34 extends cylindrically from a position on the inner side of the outer peripheral edge of the other end face 31a of the bottom wall 31. The outer diameter of the small-diameter portion 34 is smaller than the outer diameter of the other end face 31a of the bottom wall 31 and the peripheral wall 32. The three through holes 33 of the bottom wall 31 pass through the small-diameter portion 34.

[0027] The joint 30 has one screw hole 34a on the side of the small diameter portion 34. The inner circumference of the screw hole 34a is provided with a female thread for screwing in a screw 25 (see Figure 2). Alternatively, the screw hole 34a may not have a female thread, and the groove may be cut as the screw 25 is screwed in. The joint 30 also has a groove 35 extending along the circumferential direction of the small diameter portion 34 on the other end of the small diameter portion 34 in the axial direction from the screw hole 34a. With respect to the axial direction of the joint 30, the distance from the other end face 31a of the bottom wall 31 to the groove 35 is approximately equal to the distance from one end of the body 20 (described later) to the upper surface of the rib 24 (one end of the rib). The width of the groove 35 is slightly larger than the thickness of the rib 24 of the body 20.

[0028] As shown in Figures 3 and 4, the joint 30 has a flange 36 projecting radially outward at the end on the other side of the groove 35. The flange 36 projects radially outward with respect to the bottom of the groove 35. The flange 36 has an outer circumference that follows a circular shape. The flange 36 also has a notch 36a in which a part of the circular outer circumference is cut out in an arc shape. The end face of the notch 36a extends in a straight line. Three notches 36a are formed at approximately equal intervals along the circumferential direction of the small diameter portion 34.

[0029] The flange 36 has three flange portions 37, each having a circular outer circumference, positioned between three notches 36a along the circumferential direction of the small-diameter portion 34. In other words, the joint 30 has multiple flanges. The three flange portions 37 do not have to be formed completely independently of each other. The three flange portions 37 may be connected to each other on the inner circumference side of the groove 35. That is, the three flange portions 37 may appear to be configured as a single plate. The flange 36 has three flange portions 37 because it is divided circumferentially by the notches 36a.

[0030] The three flange portions 37 are also formed at approximately equal intervals along the circumferential direction of the small-diameter portion 34. Furthermore, the three flange portions 37 have the same shape. Therefore, the three flange portions 37 are rotationally symmetrical on the same circumference. The three flange portions 37 function as retaining parts, which will be described later. The material of the joint 30 is not particularly limited, but it is preferable if it is made of metal because it has excellent strength and heat resistance. In addition, it is preferable that at least the side of the water supply pipe 16, hot water supply pipe 17, and discharge pipe 18 that is connected to the joint 30 is made of metal. Furthermore, it is preferable that they are brazed to the joint 30.

[0031] <Body Details> As shown in Figures 5 and 6, the body 20 is cylindrical. The inner diameter of the opening 20a located at one end of the body 20 is slightly larger than the outer diameter of the small-diameter portion 34 of the joint 30, and smaller than the outer diameter of the other end face 31a of the bottom wall 31 of the joint 30.

[0032] The body 20 has ribs 24 projecting radially inward on its inner circumference at a position between the axial side opening 20b and the insertion hole 22. Three ribs 24 are formed on the inner circumference of the body 20 at approximately equal intervals on the same circumference. The tip surfaces of the ribs 24 extend in a straight line.

[0033] As shown in Figure 6, when the body 20 is viewed from above, the ribs 24 have an arched shape that forms part of a circle. The three ribs 24 have the same shape. Therefore, the three ribs 24 are rotationally symmetrical on the same circumference. The arched shape of the ribs 24 is the same as the arched shape cut out in the notch 36a of the flange 36 of the joint 30. Note that "same shape" means that the shapes are approximately the same, and a slight error is allowed. The three ribs 24 function as retaining parts, which will be described later. Because the three ribs 24 have the same shape as the arched shape cut out in the notch 36a of the flange 36 of the joint 30, the area of ​​engagement between the three ribs 24 and the three flange parts 37 can be made relatively larger when they engage with each other. This allows the joint 30 to be retained from the body 20 in a more stable state. The material of the body 20 is not particularly limited, but it is preferable to use resin because it is lightweight and easy to mold.

[0034] <Mechanism to prevent joint detachment from the body> As shown in Figure 7, when attaching the joint 30 to the body 20, the body 20 and the joint 30 are positioned so that the axial direction of the body 20 and the axial direction of the joint 30 are on the same axis.

[0035] Figures 7 and 8 show a cross-sectional view of the joint 30 in the plan view of the body 20, specifically the position where it engages with the rib 24 of the body 20.

[0036] As shown in Figure 7, next, the circumferential positions of the body 20 and the joint 30 are adjusted so that the three ribs 24 of the body 20 and the three flange portions 37 of the joint 30 do not overlap along the axial direction of the body 20. Then, the small diameter portion 34 of the joint 30 is brought close to the opening 20a at one end of the body 20 and inserted into the opening 20a at one end of the body 20. The other end face 31a (see Figure 4) of the bottom wall 31 of the joint 30 is brought into contact with the end of the body 20 at one end.

[0037] As shown in Figure 8, the joint 30 is then rotated relative to the body 20 in the circumferential direction, as indicated by the arrow. The three ribs 24 of the body 20 are then aligned with the three flange portions 37 of the joint 30 along the axial direction of the body 20. Note that in Figure 8, the three flange portions 37 are aligned with the back of the plane of the three ribs 24.

[0038] Figure 9 is a side view of the state shown in Figure 8. The body 20 is shown in a partial cross-sectional view. As shown in Figure 9, when the rib 24 of the body 20 is aligned with the flange portion 37 of the joint 30 along the axial direction of the body 20, the flange portion 37 of the joint 30 is positioned on the other end of the rib 24 of the body 20. The rib 24 of the body 20 is then inserted into the groove 35 of the joint 30. As a result, the rib 24 of the body 20 and the flange portion 37 of the joint 30 engage with each other and are prevented from coming apart.

[0039] Furthermore, the insertion hole 22 of the body 20 and the screw hole 34a of the small diameter portion 34 of the joint 30 are in the same position. As shown in Figure 9, the through-hole 22 is composed of a large-diameter portion into which the head of the screw 25 (see Figure 2) can be inserted, and a small-diameter portion through which the threaded portion of the screw 25 is inserted without the head being inserted. This ensures that the head of the screw 25 is positioned radially inward from the circumferential surface of the body 20. The through-hole 22 may also be configured with only the small-diameter portion, by omitting the large-diameter portion. In this configuration, the head of the screw 25 protrudes from the circumferential surface of the body 20. The through-hole 22 is elongated along the circumferential direction of the body 20 so that the position in which the screw 25 is attached can be finely adjusted along the circumferential direction of the body 20. The shape of the through-hole 22 may be a perfect circle or an elongated shape that is long in the axial direction of the body 20.

[0040] The three ribs 24 located on the same circumference and the three flange portions 37 located on the same circumference engage with each other, making it possible to relatively reduce the dimensions (length) of the area where the body 20 and joint 30 engage in the axial direction. In other words, the three ribs 24 engage with each other through one identical circumference and the three flange portions 37 engage with another identical circumference. Therefore, the dimensions (length) of the area where the body 20 and joint 30 engage in the axial direction are contained within the thickness of the two circumferences. This contributes to miniaturization of the faucet body 12 in the axial direction compared to a configuration where the three ribs 24 are formed at different axial positions on the body 20 and the three flange portions 37 are formed at different axial positions on the joint 30.

[0041] From the state shown in Figure 9, the threaded portion of the screw 25 is further inserted through the insertion hole 22 of the body 20, as shown in Figure 2, and the screw 25 is screwed into the threaded hole 34a of the small diameter portion 34 of the joint 30. This suppresses the relative rotation of the joint 30 with respect to the body 20. The screw 25 functions as a rotation-preventing member that restricts the relative rotation of the body 20 and the joint 30. By screwing in the screw 25, it becomes more difficult to release the engagement between the rib 24 of the body 20 and the flange portion 37 of the joint 30.

[0042] <Mechanism for defining the rotation range of the cover using a stopper member> As shown in Figure 2, the stopper member 60 has a pair of plate-shaped arms 61 that curve and extend along a substantially circular shape, and protrusions 62 that project from the base ends of the pair of arms 61 toward the outer circumference of the pair of arms 61. The total length of the pair of arms 61 is shorter than the length of the groove 21 that runs along the circumferential direction of the body 20. The stopper member 60 overcomes the outer circumference of the body 20 as the tips of the pair of arms 61 elastically deform and expand in diameter. Furthermore, the tips of the pair of arms 61 elastically deform and contract in diameter to fit into the groove 21 of the body 20.

[0043] Furthermore, the cover 15 of the faucet 10 has a recess (not shown) on its inner circumference into which the convex portion 62 of the stopper member 60 engages. Therefore, when the cover 15 is attached to the faucet body 12, the convex portion 62 of the stopper member 60 engages with the recess of the cover 15. As a result, when the cover 15 is rotated circumferentially relative to the faucet body 12, the stopper member 60 also rotates together with the cover 15. The pair of arms 61 of the stopper member 60 can rotate the cover 15 within the range in which movement is permitted within the groove 21 of the body 20. This allows the rotation range of the cover 15 relative to the body 20 to be defined as a certain range. By rotating the cover 15 within a certain range, it becomes possible to change the direction of the water outlet head 19 and use the faucet 10.

[0044] <Operation and Effects of This Embodiment> (1) The faucet 10 comprises a cylindrical body 20 and a bottomed cylindrical joint 30 inserted into the body 20. The body 20 and the joint 30 have ribs 24 (retaining parts) and flange parts 37 (retaining parts) that engage with each other to prevent them from coming loose. By engaging the ribs 24 of the body 20 and the flange parts 37 of the joint 30 with each other, the joint 30 can be attached to the body 20 in a state where it is prevented from coming loose. Since the joint 30 can be prevented from coming loose without using screws, the work of attaching the joint 30 to the body 20 can be simplified.

[0045] (2) The faucet 10 is equipped with a screw 25 (rotation-preventing member) that restricts the relative rotation of the body 20 and the joint 30. The screw 25 restricts the relative rotation of the body 20 and the joint 30. Therefore, it is made more difficult for the engagement between the rib 24 of the body 20 and the flange portion 37 of the joint 30 to be released. In addition, since the relative rotation can be restricted using one screw 25, the work can be simplified compared to the configuration in which three screws are used to restrict the relative rotation.

[0046] (3) The faucet 10 can be secured in multiple places using the three ribs 24 and the three flange portions 37. Therefore, the joint 30 can be secured to the body 20 in a more stable manner.

[0047] (4) The flange 36 of the joint 30 has an outer circumference that follows a circular shape and a notch 36a in which a part of the circular shape is cut out in an arc shape. The rib 24 of the body 20 has the same shape as the arc shape. When the flange portion 37 of the joint 30 and the rib 24 of the body 20 engage with each other, the area of ​​engagement can be made relatively larger. Therefore, the joint 30 can be prevented from coming off the body 20 in a more stable state. In addition, the strength of the area where the rib 24 of the body 20 and the flange portion 37 of the joint 30 engage can be improved.

[0048] (5) The faucet 10 includes a body 20 and a cover 15 that houses the joint 30. Therefore, in a faucet 10 that includes a body 20 and a cover 15 that houses the joint 30, the joint 30 can be easily attached to the body 20.

[0049] <Example of changes> This embodiment can be implemented with the following modifications. This embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0050] In this embodiment, the joint 30 was configured as a bottomed cylindrical shape, but it is not limited to this configuration. The joint 30 may be a bottomed cylindrical shape other than a cylindrical shape. That is, the outer shape of the peripheral wall 32 of the joint 30 may be rectangular, elliptical, oval, or the like. Similarly, the body 20 is not limited to a cylindrical shape. Similar to the peripheral wall 32 of the joint 30, the outer shape of the body 20 may be a cylindrical shape other than a cylindrical shape. It is preferable that the inner shape of the peripheral wall 32 of the joint 30 and the inner shape of the body 20 have cylindrical inner surfaces.

[0051] In this embodiment, the ribs 24 of the body 20 and the flange portion 37 of the joint 30 were engaged with each other, and then a screw 25, which serves as a rotation-preventing member, was screwed into the screw hole 34a of the joint 30. This is how the joint 30 was attached to the body 20, but the embodiment is not limited to this. The screw 25 may be omitted. That is, the joint 30 may be attached to the body 20 simply by engaging the ribs 24 of the body 20 and the flange portion 37 of the joint 30 with each other.

[0052] As shown in Figure 2, the body 20 is fixed to the wall 11 by fixing members (not shown). The water supply pipe 16, the hot water supply pipe 17, and the discharge pipe 18 are connected to the joint 30. Therefore, rotation in the circumferential direction of the body 20 and the joint 30 is unlikely. As a result, the joint 30 can be attached to the body 20 simply by engaging the rib 24 of the body 20 with the flange portion 37 of the joint 30, without using screws 25 as anti-rotation members. Since there is no need to screw in screws 25, the installation work of the joint 30 to the body 20 can be further simplified.

[0053] In this embodiment, the three ribs 24 of the body 20 and the three flange portions 37 of the joint 30 were engaged with each other, but the embodiment is not limited to this. The ribs 24 of the body 20 may be one, two, or four or more. Similarly, the flange portions 37 of the joint 30 may be one, two, or four or more.

[0054] The ribs 24 of the body 20 and the notched shape of the notch 36a in the joint 30 do not have to be the same shape. Also, these shapes do not have to be arched. The outer circumference of the flange portion 37 does not have to follow a circular shape. Also, the three flange portions 37 do not have to be the same shape.

[0055] In this embodiment, the rib 24 of the body 20 and the flange portion 37 of the joint 30 are engaged with each other, but the embodiment is not limited to this. Any shape other than the rib 24 and flange portion 37 is acceptable as long as the body 20 and the joint 30 are configured to engage in a retaining state by rotating relative to each other. For example, a groove may be provided on the inner circumference of the body 20, extending axially from one end to the other end and bending in the circumferential direction.
