Description

  The present invention relates to an attachment device for attaching a faucet body to an attachment portion.

  The faucet usually has a faucet body with a built-in valve mechanism (valve device, etc.), an operation section (operating handle, lever, etc.) for operating the valve mechanism, and a fluid (hot water, water, etc.) flowing out from the faucet body. Or water discharge means (such as a currant or a shower head) for discharging water (mixed water obtained by mixing hot water and water).

In such a faucet, the faucet body is attached to an attachment part (base part, wall part, etc.) provided in the use space (kitchen, washroom, bathroom, etc.) and below the attachment part (attachment part) In the case of a base part) or behind the attachment part (in the case where the attachment part is a wall part, etc.), there is a connection between the original pipe and the pipe provided in the faucet (see Patent Document 1, Hereinafter referred to as “conventional example”).
JP-A-8-302769

  According to the faucet according to this conventional example, depending on the situation of the usage space, the work of attaching to the attachment portion may not be performed smoothly and reliably. Hereinafter, this point will be described using a specific example shown in FIG.

  The faucet 100 according to this specific example is a so-called type (deck type) with a faucet body 110 attached to a base part (deck part) 200 for use. A sliding valve device (not shown) is built in the faucet body 110 that constitutes the faucet 100, and a lever handle 120 for operating the sliding valve device is provided above the faucet body 110. Is installed. Further, on the lower end portion side of the faucet body 110, a hot water connection pipe 130 for supplying hot water to the faucet body 110, and a water supply connection pipe 140 for supplying water to the faucet body 110, Is arranged.

  Further, the primary side end of the hot water supply connection pipe 130 is connected to the “terminal portion 211 of the hot water supply original pipe 210 previously set below the base part 200”, and the water supply connection pipe 140 The end on the primary side is connected to “the terminal portion 221 of the water supply main pipe 220 previously installed below the base portion 200”. The lever handle 120 is appropriately rotated and tilted so that hot water (hot water, water, or mixed water in which hot water and water are mixed) can be discharged from the shower head 230. Yes.

  By the way, normally, the construction of the main pipes 210 and 220 and the construction of the faucet 100 are performed by different contractors. In other words, prior to the construction of the faucet 100, the main pipe construction company installs the terminal part 211 of the main pipe 210 for hot water supply and the terminal part 221 of the main pipe 220 for water supply below the base part 200. I do. Both terminal portions 211 and 221 installed by this work are normally in a state of opening vertically upward at a position approximately equidistant from the back wall portion 250 located below the base portion 200. Then, the faucet installer performs the operation of connecting the hot water supply connection pipe 130 and the water supply connection pipe 140 to the terminal portions 211 and 221 installed in this manner.

  However, depending on the mounting mode of the faucet 100 and the state of the base part 200, it may be difficult to smoothly and reliably perform the operation of attaching the faucet body 110 to the base part 200. That is, the faucet 100 is usually attached in a state where the lever handle 120 faces the front front (hereinafter referred to as “basic state”) (see FIG. 27), but depending on the attachment mode of the faucet 100, It may be necessary to orient the axis of the lever handle 120 in an oblique direction or the like.

  For example, as in the faucet 100A shown in FIG. 28, the faucet body 110A may be attached to a portion located obliquely behind the corner portion 302 of the sink water tank 301 on the upper surface portion of the sink 300. In such a case, for the user located in front of the center portion of the sink water tank 301, the lever handle 120 is directed toward the diagonal direction (specifically, the diagonal direction of the sink water tank 301 or a direction closer to the diagonal line). This is because the operability of 120 is improved. In such a case, if the lever handle 120 is facing frontward, the operability of the lever handle 120 is low for the user located in front of the center of the sink basin 301 or the lever handle 120 There are times when it is out of reach. As a next best measure, when the entire length of the lever handle 120A is increased as shown in FIG. 28, the lever handle 120A collides with the wall portion 380 around the sink 300, and the usability of the lever handle 120A is further improved. May be reduced.

  Thus, as in the case of the lever handle 120 of FIG. 28, in order to orient the direction in an oblique direction, it is necessary to change the mounting state of the faucet body 110A with respect to the upper surface portion of the sink 300. For example, as shown in FIG. 28, the faucet body 110A is rotated about 45 degrees around a rotation axis in the vertical direction (a state where the faucet body 110A is rotated about 45 degrees based on the basic state described above, In this case, as shown in FIG. 29, a hot water supply connecting pipe 130 that hangs down from the lower end of the faucet main body 110 is attached to the upper surface of the sink 300. The connection pipe 140 for water supply also rotates about 45 degrees around the aforementioned rotation axis. FIG. 29 shows the positional relationship between the “hot-water supply connection pipe 130 and the water supply connection pipe 140” and the “terminal part 211 of the hot water supply original pipe 210 and the terminal part 221 of the water supply original pipe 220”. FIG. 29A shows a positional relationship before the rotation of both the connecting pipe 130 and the connecting pipe 140, and FIG. 29B shows the both connecting pipe 130 and the connecting pipe. The positional relationship after adding rotation to 140 is shown.

  Thus, when the connection pipe 130 for hot water supply and the connection pipe 140 for water supply are rotated about 45 degrees around the aforementioned rotation axis, the relative positions of the connection pipes 130, 140 and the terminal portions 211, 221 will be described. Therefore, the length of one of the connecting pipes 130 and 140 becomes excessive (excessive when the terminal portions 211 and 221 and the faucet body 110 are connected). There is a possibility of inconvenience such as the other length of the other side becoming insufficient. In this case, it is necessary to cut off an excess portion of one connection pipe 130 (140) in millimeters, and the connection work between the connection pipes 130 and 140 and the terminal portion 211 (221) may be troublesome. is there. Or, the sealing failure between the other connection pipes 130 and 140 and the terminal part 221 (211) occurs, or the connection itself between the other connection pipes 130 and 140 and the terminal part 221 (211) is impossible. This is because there is a possibility of becoming.

  Further, when there is an obstacle below the base part 200, any one of the connecting pipes 130 and 140 is turned into the obstacle by rotating the connecting pipes 130 and 140 about 45 degrees around the rotation axis. There is a possibility of conflict. Even in such a case, it may be difficult to connect the connecting pipes 130 and 140 to the terminal units 211 and 221. That is, in order to connect the connection pipes 130 and 140 to the terminal units 211 and 221, it is necessary to reach the terminal units 211 and 221 while passing through a route around an obstacle. However, this is because the lengths of the connecting pipes 130 and 140 may be insufficient, making it impossible to reach the terminal units 211 and 221 in some cases.

  The above problem has been described by taking the hot and cold water mixing faucet as an example, but the same problem can occur in a single faucet. That is, even when one connection pipe hangs down from the faucet body 110 in order to allow fluid (hot water, water, or mixed water) to flow into the faucet body 110, the connection pipe is rotated around the rotation axis of the faucet body 110. The rotation of the connection pipe may cause a change in the positional relationship between the connection pipe and the terminal portion of the original pipe, and the connection between the connection pipe and the terminal section of the main pipe may not be accurately performed. In addition, the connection pipe rotates around the rotation axis of the faucet body 110, so that there is a possibility that the connection pipe may come into contact (impact) with an obstacle below the base portion 200.

  This invention solves the above-mentioned subject, and provides the attachment apparatus which can perform the operation | work which attaches a faucet to various attachment parts smoothly and reliably irrespective of the condition of use space. With the goal.

The attachment device of the invention of claim 1
An attachment device for attaching a faucet body incorporating a valve mechanism to an attachment portion,
A fixed mounting member fixed to the mounting portion and having a recess for insertion;
A movable mounting member that has an insertion portion that is inserted in a rotatable state with respect to the insertion recess, and that holds the faucet body in an integrally rotatable state;
With
A fluid supply channel is formed in the fixed mounting member, and a reaching channel for allowing the fluid supplied through the fluid supply channel to reach the faucet body is formed in the movable mounting member,
The end on the secondary side of the fluid supply channel that opens at the bottom of the recess for insertion and the end on the primary side of the reaching channel that opens at the outer surface of the insert are the insertion It communicates, being arrange | positioned on the rotating shaft center of a part.

  Here, in this specification, “mixed water” and “hot water” are defined as follows. In other words, “mixed water” is generated by mixing “hot water (hot water supplied from a hot water source such as a water heater)” and “water (water supplied from a water source such as a terminal of a water pipe)”. Refers to "Yumizu". Also, “hot water” is used as “generic name for fluids handled by faucets”. That is, “hot water” includes “hot water (hot water supplied from a hot water supply source)”, “water (water supplied from a water supply source)”, and “mixed water”. Further, in this specification, “fluid” is used as “a general term for fluids handled by faucets”. That is, since it is used in the same meaning as “hot water”, the “fluid supply channel” of the invention of claim 1 may be a channel through which hot water passes or a channel through which water passes. Alternatively, it may be a flow path through which the mixed water passes.

  The mounting device according to the first aspect of the present invention includes a fixed mounting member fixed to the mounting portion, and a movable mounting for holding the faucet body in a rotatable state while being mounted on the fixed mounting member in a rotatable state. And a member. Regardless of the rotational position of the movable mounting member (insertion portion), the fluid supply flow path of the fixed mounting member and the reaching flow path of the movable mounting member are always in communication. And the faucet body attached to the attachment part using the attachment device connects the end part on the primary side of the fluid supply flow path and the terminal part of the original pipe to a connecting member (for example, a copper tube or a flexible hose). It can be used if it is connected using a connecting pipe constructed by using the connecting pipe).

  In the attachment device according to the first aspect of the present invention, the faucet body can be rotated without changing the positional relationship between the primary side end of the fluid supply flow path and the end of the original pipe. For this reason, fixing to the mounting portion of the fixed mounting member is in a convenient state for connecting the end portion on the primary side of the fluid supply flow path and the terminal portion of the original pipe using the connecting member. Just do it. Then, for example, after the faucet body is supported by the fixed mounting member via the movable mounting member, a desired rotation is applied to the faucet body, so that the “operating portion for operating the valve mechanism” is obtained as desired. It can be directed in the direction.

  Thus, in the mounting device of the invention of claim 1, the fixed mounting member involved in the connection with the terminal portion of the original pipe and the movable mounting member involved in the connection with the faucet body are separated, and the fixed mounting member The movable mounting member can be turned on the basis of. In other words, according to the attachment device of the first aspect of the present invention, the faucet body can be rotated around the rotational axis of the insertion portion according to the situation of the use space. The attaching operation can be performed smoothly and reliably.

  In addition, according to the invention of each claim, it can respond to the reform of the usage space quickly and accurately, and can also accurately correspond to the situation of the usage space (attachment portion) that has been diversified in recent years.

  In other words, even when replacing the existing faucet with another faucet at a predetermined mounting part, this replacement work can be done by replacing the movable attachment member and faucet body or replacing the faucet body. It can be performed. That is, this replacement work can be performed in a state where the fixed attachment member involved in the connection with the terminal portion of the original pipe is attached to the attachment portion. In other words, this replacement operation can be performed while maintaining the connection state using the connection member between the primary side end of the fluid supply flow path and the terminal portion of the original pipe as it is. For example, at the time of renovation etc., it is sufficient to carry out the construction above the mounting part (when the mounting part is a base part) or forward (when the mounting part is a wall part), and below the mounting part (the mounting part is a base). It is not necessary to carry out construction in the case of a part) or behind (when the mounting part is a wall part, etc.). Therefore, according to the first aspect of the present invention, it is possible to quickly and accurately cope with the reform of the use space of the faucet.

  In recent years, the situation of use spaces (mounting portions) has been diversified. For example, a sink may be installed in a part other than the kitchen wall (for example, the center). In this case, the faucet attached to the sink may be operated from a plurality of directions (for example, in front of and behind the sink). Requested. And it can respond to this request exactly by using the attachment device of the invention of each claim. That is, since the faucet body (water faucet) attached to the attachment portion using the attachment device of the invention of each claim can be rotated integrally with the movable attachment member, the direction of the operation portion is a desired direction. It is because it can turn to.

  In this specification, examples of the “use space” include a kitchen, a washroom, a bathroom, a toilet, and a laundry room. In addition, examples of the “attachment portion” of the invention of each claim include a base portion and a wall portion provided in this use space.

  The faucet body (water faucet) of each claim may be integrated with water discharge means or detachably attached thereto. However, the water discharge means may be disposed at a position away from the faucet body (water faucet). In this case, the fluid flowing out from the faucet body (water faucet) is discharged using a predetermined pipe or the like. To reach. Examples of the water discharge means include currants, water discharge heads (shower heads), and the like. Furthermore, a plurality of water discharging means (for example, a currant and a water discharging head) are disposed on the secondary side of the faucet body of the invention of each claim, and a plurality of water discharging means using a valve mechanism built in the water faucet body. It may be possible to select which of these is used for water discharge.

  Various types of valve mechanisms incorporated in the faucet body of the invention of claim 1 can be selected, (1) a valve mechanism for selecting water to be stopped, (2) selection of water to be discharged and selection of water discharge amount (3) A valve mechanism for selecting a water discharge flow path, (4) A valve mechanism for selecting a water discharge flow path and selection of water discharge, (5) Water discharge flow Examples thereof include a valve mechanism for selecting a path, selection of water discharge, and selection of water discharge amount. Further, in this specification, “selection of water discharge flow path” means that a target faucet includes a plurality of water discharge flow paths (for example, a water discharge flow path connected to a currant and a shower water discharge flow path connected to a shower). In this case, it means “selecting the water discharge channel to be used”.

  The “operation unit” of the invention of each claim includes a handle type operation unit (rotation operation) in addition to a lever type operation unit (operation unit to which at least one of rotation operation and tilting operation is performed). Operation part), push type operation part (push switch type operation part), foot switch type operation part, non-contact type operation part (those using non-contact type human sensor, etc.), etc. It can be illustrated. In the present specification, the direction of the lever-type operation unit is determined based on a state where the operation unit is not operated (neutral state). That is, when the operation unit is not operated, the direction in which the tip of the lever faces is the direction of the lever type operation unit.

  In the invention of each claim, the rotation range (rotation range) of the insertion portion inserted into the insertion recess may be unlimited, or may be limited to a certain range. For example, the insertion portion may be rotatable around its rotational axis. Further, the insertion portion may be rotatable by 180 degrees to the left and right with reference to a predetermined rotation position (for example, the rotation position where the operation portion faces the front front) (that is, the insertion portion may be rotated about its rotation axis). It is possible to rotate 360 degrees around the center), and it is possible to rotate by a certain angle smaller than 180 degrees to the left and right with reference to a predetermined rotation position (for example, a rotation position where the operation unit faces the front front). It is good. In an aspect in which the rotation range (rotation range) is limited, whether or not the angle that can be rotated in the right rotation direction with respect to the predetermined rotation position matches the angle that can be rotated in the left rotation direction. It doesn't matter.

The mounting device of the invention of claim 2 is the mounting device of claim 1,
A second fluid supply channel is formed in the fixed mounting member separately from the fluid supply channel, and one of the fluid supply channel and the second fluid supply channel is hot water supply. And the other is a water supply channel,
In the movable attachment member, a second reaching channel is formed separately from the reaching channel, and the fluid supplied through the second fluid supplying channel is passed through the second reaching channel. Reach the faucet body,
An inflow side communication space is provided between the inner wall portion of the insertion recess and the outer surface portion of the insertion portion to draw a substantially annular or substantially arc-shaped path,
An end on the primary side of the second reaching flow path that opens at the outer surface of the insertion portion, and a secondary side of the second fluid supply flow path that opens at the inner wall of the insertion recess. The end portion communicates with the inflow side communication space.

  The mounting device of the invention of claim 2 shows an application example to a hot and cold water mixing faucet. And when constructing a faucet, there are two main pipes that supply fluid to the faucet body (that is, there are a main pipe for hot water supply and a main pipe for water supply). Therefore, it becomes more susceptible to the influence of the usage space. That is, when the faucet body is rotated around a predetermined rotation axis in the vertical direction, as described above, the primary side end of the hot water supply channel and the primary side end of the water supply channel, Deviation occurs in the relative position with respect to the terminal portion of each original pipe (see FIG. 29). For this reason, “a connecting member for hot water supply (connecting pipe for hot water supply) for connecting the end of the primary side of the hot water supply passage and the terminal portion of the original pipe for hot water supply”, “ The length of one of the “primary water supply connecting member (water supply connecting pipe)” for connecting the primary side end of the water supply and the end of the water supply original pipe is excessively small, This is because there is a possibility of inconvenience that the length becomes insufficient.

  On the other hand, in the mounting device according to the second aspect of the present invention, “the positional relationship between the primary side end of the hot water supply channel and the terminal portion of the hot water supply original pipe” and “1 of the water supply channel” The water faucet body can be rotated (rotated) by a predetermined amount without changing the positional relationship between the “positional relationship between the end on the next side and the terminal portion of the original pipe for water supply”. In the mounting device according to the second aspect of the present invention, since the “inflow communication channel” is provided, the second fluid supply channel and the second fluid flow channel are provided even if the faucet body (insertion portion) is rotated by a predetermined amount. It is possible to maintain the communication state with the reaching flow path.

  For this reason, the fixing mounting member is fixed to the mounting portion by using a hot water connection member between the primary side end of the hot water supply flow path and the terminal portion of the original hot water supply pipe, and for water supply. What is necessary is just to carry out so that it may be in a convenient state when connecting using the connection member for water supply with the edge part of the primary side of a flow path, and the terminal part of the original piping for water supply. Then, for example, after the faucet body is supported by the fixed mounting member via the movable mounting member, a desired rotation is applied to the faucet body, so that the “operating portion for operating the valve mechanism” is obtained as desired. It can be directed in the direction.

  Thus, also in the attachment device of the invention of claim 2, the fixed attachment member involved in the connection with the terminal portion of the original piping and the movable attachment member involved in the connection with the faucet body are separated and fixed attachment. The movable attachment member can be rotated with respect to the member. Therefore, according to the attachment device of the invention of claim 2, the faucet body can be rotated around the rotational axis of the insertion portion according to the situation of the use space, so that the faucet can be attached to various attachment portions. Installation work can be performed smoothly and reliably. Further, in the invention of claim 2, as described above, it is possible to respond quickly and accurately to the reformation of the usage space, or to accurately respond to the diversified usage space (attachment portion) in recent years. .

  Various types of valve mechanisms built into the faucet body of the invention of claim 2 can be selected, (a) a valve mechanism for adjusting the water discharge temperature, (b) adjusting the water discharge temperature and selecting the water discharge. The valve mechanism for this can be illustrated. Moreover, in the valve apparatus of (b), selection of the amount of water discharge may be performed with selection of the water discharge. Furthermore, the faucet body of the invention of claim 2 may include a plurality of valve mechanisms. For example, you may provide the valve mechanism for adjusting water discharge temperature, and the valve mechanism for selecting the water discharge while being arrange | positioned at the secondary side of this valve mechanism. Further, the “valve mechanism for selecting water discharge” may select the water discharge amount.

  In the invention of claim 2, the primary side end of the second reaching flow path and the secondary side end of the second fluid supply flow path are eccentric from the rotation axis of the insertion portion. Open to position.

  The “inflow side communication space” according to the second aspect of the invention is a substantially annular path or substantially along the direction of rotating around the outer surface portion (outer peripheral portion) of the insertion portion (the direction of rotation around the rotational axis of the insertion portion). It is formed in a state of drawing an arcuate path. Further, the method for forming the “inflow side communication space” of the invention of claim 2 can be selected in various ways. For example, (1) at least one of the inner wall portion of the insertion concave portion and the outer surface portion of the insertion portion is rotated on the insertion portion. A concave portion that draws a substantially circular path or a substantially arc-shaped path around the dynamic axis is formed, and an “inflow side communication space” is formed between the inner wall portion of the insertion concave portion and the outer surface portion of the insertion portion by the concave portion. Aspect, (2) An aspect in which the outer diameter of the insertion portion is narrowed to provide a space between the inner wall portion of the insertion recess and the outer surface portion of the insertion portion, and this space forms an “inflow side communication space”, or ( A mode of forming an “inflow side communication space” by both 1) and (2) can be exemplified.

  In addition, when the “inflow side communication space” draws a substantially annular (circular) path, the second fluid supply channel and the second fluid supply channel and the second flow path are independent of the rotation position (rotation amount) of the faucet body and the insertion portion. It is possible to always communicate with the reaching channel. Further, when the “inflow side communication space” draws a substantially arc-shaped route, the communication state between the second fluid supply channel and the second reaching channel can be maintained according to the central angle of the route. “Rotation amount of faucet body and insertion part” is determined. The central angle of the path of the substantially arc is preferably 60 degrees or more, more preferably 120 degrees or more, and still more preferably 180 degrees or more (less than 360 degrees). However, the communication state between the second fluid supply flow channel and the second reaching flow channel can be intentionally canceled by making the central angle of the substantially circular arc path smaller than 360 degrees. . In other words, according to the attachment device of the second aspect of the present invention, the water faucet body is rotated by a specific amount, and the communication state between the second fluid supply channel and the second reaching channel is released, thereby A mixed faucet can also be used like a single faucet.

  In addition, when the “inflow side communication space” draws a substantially arc-shaped path, the “circumferential width of the primary side end of the second reaching flow path (around the rotation axis of the insertion portion). Width along the direction in which the second fluid supply channel is disposed, and the width in the circumferential direction of the second fluid supply channel (the width along the direction of the circumference of the rotation axis of the insertion portion). However, it is desirable to be smaller than “a circumferential width of the inflow side communication space (a width along a direction around the rotation axis of the insertion portion)”.

  In the mounting device according to the second aspect of the present invention, a flow passage portion for supplying hot water to the faucet body (hereinafter referred to as “flow passage portion for hot water supply”) and a flow passage portion for supplying water to the faucet body ( Hereinafter, the space between the “water supply flow path portion” and the like is sealed using a seal member (packing or the like). For example, the seal member is mounted in a mounting groove formed in a circular shape (annularly formed) on the inner wall portion of the insertion recess or the outer surface portion of the insertion portion, and the inner wall portion of the insertion recess and the outer surface portion of the insertion portion. The gap that may occur between the two will be closed.

  In other words, this seal member is attached to the inner wall portion of the insertion recess or the outer surface portion of the insertion portion, and “the end portion on the secondary side of the fluid supply channel, the end portion on the primary side of the reaching channel, and "Inflow side communication space" and "secondary end of the second fluid supply channel, primary end of the second reaching channel and second inflow communication space" Sealing in between. For example, a seal member is disposed on both sides of the inflow side communication space (both sides along the axial direction of the insertion portion), and the second fluid supply is performed in a region sandwiched between the seal members. The end on the secondary side of the flow path for opening and the end on the primary side of the second reaching flow path are opened.

The attachment device of the invention of claim 3 is the attachment device of claim 1 or claim 2,

A secondary side end of the passage channel that opens at the outer surface of the insertion part and a primary side end of the outflow channel that opens at the inner wall part of the insertion recess are the outflow side. It is characterized by communicating through a communication space.

  The invention according to claim 3 shows a mode in which a flow channel portion (hereinafter referred to as “flow channel portion for outflow”) through which the fluid (hot water) flowing out from the faucet body passes is provided in the attachment device. Since the attachment device according to the third aspect includes the “outflow side communication space”, the passage channel and the outflow channel communicate with each other even if the faucet body is rotated by a predetermined amount.

  The “outflow side communication space” of the invention of claim 3 is also a substantially annular path or substantially along the direction of rotating around the outer surface portion (outer peripheral portion) of the insertion portion (the direction of rotation around the rotation axis of the insertion portion). It is formed in a state of drawing an arcuate path. Further, the method for forming the “outflow side communication space” of the invention of claim 3 can be selected in various ways. For example, (a) the insertion portion is arranged on at least one of the inner wall portion of the insertion recess and the outer surface portion of the insertion portion. A concave portion that draws a substantially annular path or a substantially arc-shaped path around the dynamic axis is formed, and this concave portion forms an “outflow side communication space” between the inner wall portion of the insertion concave portion and the outer surface portion of the insertion portion. Aspect, (b) An aspect in which the outer diameter of the insertion portion is narrowed down to provide a space between the inner wall portion of the insertion recess and the outer surface portion of the insertion portion, and this space forms an “inflow / outflow communication space”, or the like, An example in which the “inflow side communication space” is formed by both (a) and (b) can be exemplified.

  When the “outflow side communication space” draws a substantially circular (circular) path, the passage channel and the outflow channel are always connected regardless of the rotation position (rotation amount) of the faucet body and the insertion portion. Can communicate. In addition, when the “inflow side communication space” draws a substantially arc-shaped route, the “water faucet body and the insertion portion that can maintain the communication state between the passage channel and the outflow channel according to the central angle of the route” Rotation amount "is determined. The central angle of the path of the substantially arc is preferably 60 degrees or more, more preferably 120 degrees or more, and still more preferably 180 degrees or more (less than 360 degrees).

  In addition, when the “outflow side communication space” draws a substantially arc-shaped path, the “circumferential width of the secondary side end of the passage for passage (in the direction of circling around the rotation axis of the insertion portion) ”And the“ circumferential width of the primary side end of the outflow channel (the width along the direction of the circumference of the rotation axis of the insertion portion) ”. It is desirable to make the width smaller than the circumferential width of the side communication space (width along the direction of the circumference of the insertion portion around the rotation axis).

In the movable joint 20, a portion where the “secondary end 23 b of the hot water outflow passage 23” opens is a communication groove 30 n that is recessed inward in the radial direction of the movable joint 20 compared to the upper and lower portions thereof. It is said that. The communication groove 30n is formed so as to go around the outer peripheral portion of the movable joint 20, and a secondary end 23b is opened at the bottom of the communication groove 30n (see FIG. 8). Further, as shown in FIG. 6, the primary side end 21 a of the hot water supply reaching channel 21, the primary end 22 a of the hot water reaching channel 22, and the hot water outflow channel 23 The end 23b on the secondary side opens to a position having a predetermined distance from each other along the direction of the rotational axis J of the insertion portion 20e (a position where a positional deviation has occurred).

  A male screw portion 25 is formed on the upper end side of the outer peripheral portion of the movable joint 20. Further, in the large-diameter portion 20a, circumferential mounting grooves 26a and 26b are formed in the portion located above and below the portion "the end portion 23b on the secondary side of the hot water outflow passage 23". Sealing members (packings) P1 and P2 are mounted in the mounting grooves 26a and 26b (see FIG. 4). In the present embodiment, so-called “X packing (packing having a substantially X-shaped cross section)” is used as the seal members P1 and P2. Thereby, the frictional resistance between the inner peripheral part of the support cylinder part 51 and seal member (packing) P1, P2 is reduced, and rotation of the water discharge pipe member 50 (rotation around the axis of the support cylinder part 51) is easy. It is supposed to be.

  Further, in the outer peripheral portion of the movable joint 20, a portion (the lower half portion of the outer peripheral portion of the medium diameter portion 20 b) located above the “primary side end portion 22 a of the water supply reaching flow path 22” and “water supply Circumferential mounting grooves 26 c and 26 d are also formed in a portion (outer peripheral portion of the small diameter portion 20 d) located above the “primary side end portion 22 a” of the reaching channel 22. Seal members (packings) P3 and P4 are also mounted in the mounting grooves 26c and 26d. In the present embodiment, so-called “O-rings (packings having a substantially circular cross section)” are used as the seal members P3 and P4. Thereby, the watertightness between the inner wall part (inner wall part 13g of the recessed part 13 for insertion) of the fixed joint 10 and the outer peripheral part of the insertion part 20e is improved.

  Thus, “the frictional resistance between the seal members (O-rings) P3 and P4 mounted in the mounting grooves 26c and 26d and the inner wall portion of the fixed joint 10” is “mounted in the mounting grooves 26a and 26b. The frictional resistance between the seal members (X packing) P1 and P2 and the inner peripheral portion of the support cylinder portion 51 is set to be larger, that is, the fluid force of the “flow path for allowing fluid to flow into the faucet body 30”. Is much higher than the fluid pressure of the “flow path for allowing the fluid to flow out to the faucet body 30”. That is, in the present embodiment, “the hot water supply pressure in the hot water supply flow path including the hot water supply flow path 14 a and the hot water supply arrival flow path 21” and “the water supply flow path 14 b and the hot water supply arrival flow path 22 are configured. The “water supply pressure in the water supply system flow path” is higher than the “fluid pressure in the water discharge system flow path including the hot water outflow flow path 23 and the like”.

  Nevertheless, in the present embodiment, the hot water supply system flow path and the water supply system flow path are “a plurality of flow paths provided in separate members (fixed joint 10 and movable joint 20) arranged to be relatively rotatable”. (A combination of the hot water supply flow path 14a and the hot water supply reaching flow path 21, and a combination of the water supply flow path 14b and the hot water supply reaching flow path 22). For this reason, in the flow path of the hot water supply system and the flow path of the water supply system, the portions where the flow paths of the separate members (the fixed joint 10 and the movable joint 20) are combined (the hot water supply flow path 14a and the hot water supply reach flow path 21 communicate with each other). It is necessary to maintain particularly strong water tightness in a portion where the water supply channel 14b and the water supply reaching channel 22 communicate). Therefore, the hot water supply system flow path and the seal portion targeting the water supply system flow path are configured using “seal members P3 and P4 (O-rings) having high sealing performance.

  Furthermore, a circular retaining groove 27 is formed in the upper half of the outer peripheral portion of the medium diameter portion 20b. As will be described later, the distal end portion of the shaft portion M1 of the retaining screw M is inserted into the retaining groove 27 to prevent the movable joint 20 from being detached from the fixed joint 10 (see FIG. 4).

  Next, a construction example of the hot and cold water mixing faucet S using the attachment device T will be described. In this construction example, first, as shown in FIG. 4, a connecting pipe 5 for hot water supply and a connecting pipe 6 for water supply are connected to the fixed joint 10. In this connection, the secondary side end of the hot water supply pipe 5 is connected to the primary side end of the hot water supply channel 14a, and the water supply channel is connected to the primary side end of the water supply channel 14b. This is done by connecting the end of the secondary side of the connecting pipe 6. When this connection is made, the hot water connection pipe 5 and the water supply connection pipe 6 protrude from the fixed joint 10, and the protruding amounts of both the connection pipes 5 and 6 are made equal. In addition, the manufacturer etc. which manufactured the fixed joint 10 may complete the connection to the fixed joint 10 of both the connecting pipes 5 and 6 outside a construction site.

  Next, as shown in FIG. 8, the fixed joint 10 is attached to the sink 80. That is, the lower end portion of the fixed joint 10 (the lower end portion of the main body portion 11) is positioned above the mounting hole 80d of the base portion 80a, and the portions protruding from the fixed joint 10 in the connecting pipes 5 and 6 are the mounting holes. The main body 11 is inserted into the mounting hole 80d while being inserted through 80d. However, since the inner diameter of the mounting hole 80d is smaller than the outer diameter of the flange portion 12, the seal member 18 mounted on the lower surface of the flange portion 12 abuts on the base portion 80a (the peripheral portion of the mounting hole 80d). At this point, the insertion is complete.

  Further, as shown in FIG. 8, after the seal member 88a is mounted on the fixed joint 10 from below the base portion 80a, the fixed nut 88b is screwed onto the outer peripheral surface (the male screw portion 10m) of the fixed joint 10. Then, the mounting operation of the fixed joint 10 is completed by sandwiching the base portion 80a between the flange portion 88c of the fixed nut 88b and the flange portion 12 of the fixed joint 10.

  However, in this mounting operation, the fixed joint 10 is rotated about its axis (axis oriented in the vertical direction), and the alignment between the connection pipes 5 and 6 and the terminal portions 85H and 85C is performed. Done (see FIG. 2). In other words, the primary side end 14c of the hot water supply flow path 14a and the terminal portion 85H of the hot water supply original pipe H are connected using the hot water supply connection pipe 5 and the primary of the water supply flow path 14b. The rotational position of the fixed joint 10 is determined so as to be in a convenient state for connecting the end portion 14g on the side and the terminal portion 85C of the source pipe C for water supply using the connection pipe 6 for water supply. .

  For example, as shown to Fig.10 (a), the distance along the horizontal direction between the edge part 14c of the primary side of the flow path 14a for hot water supply, and the terminal part 85H of the original piping H for hot water supply, and water supply The rotational position of the fixed joint 10 is determined so that the distance along the horizontal direction between the primary end 14g of the flow path 14b and the terminal portion 85C of the water supply main pipe C is equal. In other words, the rotational position is determined so that both the connecting pipes 5 and 6 protruding from the fixed joint 10 can be connected to the terminal portions 85H and the terminal portions 85C under the same conditions.

  Thus, when the fixed joint 10 is attached to the base part 80a, below the base part 80a, the terminal part 85H of the main pipe H for hot water supply and the end part on the primary side of the connecting pipe 5 for hot water supply And the connection between the terminal portion 85C of the water supply main pipe C and the water supply connection pipe 6 are performed. Further, when the fixed joint 10 is attached to the base portion 80a, the insertion recess 13 is opened above the base portion 80a.

  The faucet body 30 and the like are attached to the fixed joint 10 attached to the pedestal 80a via the movable joint 20, and prior to this attachment, the attachment of the movable joint 20 to the faucet body 30 and the movable joint 20 The water discharge pipe member 50 is attached in this order. Here, as shown in FIG. 8, the mounting of the movable joint 20 to the faucet body 30 is performed by screwing the male screw portion 25 of the movable joint 20 into the female screw portion 31 a of the outer shell portion 31.

  Thereby, the faucet body 30 is held by the movable joint 20 so as to be integrally rotatable. However, at the time of the male screw portion 25 to the female screw portion 31a, the faucet body 30 and the movable joint 20 are aligned around the axis (rotation axis J described later) of the movable joint 20 as follows. Is done. That is, the secondary side end 21b of the hot water supply reaching channel 21 communicates with the hot water supply hole (not shown) of the fixed disk 32a, and the secondary side end 22b of the hot water reaching channel 22 is While communicating with a water supply hole (not shown) of the fixed disk 32a, the primary end 23a of the hot water outflow passage 23 is aligned with the outlet 32d of the fixed disk 32a.

  In order to smoothly perform this alignment, it is desirable to provide a regulating means for regulating the screwing amount of the movable joint 20 between the faucet body 30 and the movable joint 20. For example, the abutted portion is provided in the faucet body 30, the abutting portion is provided in the movable joint 20, and when the amount of screwing of the movable joint 20 to the faucet body 30 becomes an appropriate amount, the abutting portion is changed. The contacted portion may be brought into contact with the rotation direction of the movable joint 20 (rotation direction at the time of screwing) and the further rotation direction (screwing) of the movable joint 20 may be restricted.

  On the other hand, the attachment to the water discharge pipe member 50 to the movable joint 20 is performed by inserting the movable joint 20 into the support cylinder part 51 from the lower end side thereof, and the insertion part from the opening at the lower end of the support cylinder part 51. Complete by projecting 20e. With this attachment, as shown in FIG. 8, the through hole 51 a of the support cylinder 51 and the end 23 b on the secondary side of the hot water outflow channel 23 are aligned in the radial direction of the movable joint 20. For this reason, the end 23b on the secondary side of the hot water outflow passage 23 and the inside of the water discharge pipe 52 communicate with each other through the communication groove 30n and the through hole 51a.

  Further, when the water discharge pipe member 50 is attached to the movable joint 20, as shown in FIG. 8, the seal member P1 attached to the attachment groove 26a above the "secondary end 23b of the hot water outflow passage 23". Is attached in a watertight manner to a portion of the inner peripheral surface of the support cylinder portion 51 located above the through hole 51a, and the mounting groove below the “secondary end 23b of the hot water outflow passage 23”. The seal member P2 attached to 26b abuts in a watertight manner on a portion of the inner peripheral surface of the support cylinder portion 51 that is located below the through hole 51a. For this reason, the watertightness between the movable joint 20 and the water discharge pipe member 50 is maintained. Further, when the water discharge pipe member 50 is attached to the movable joint 20, the water discharge pipe member 50 can be rotated around its axis, but the inner peripheral surface of the water discharge pipe member 50 from the seal members P1, P2 above and below the through hole 51a. Friction is applied to For this reason, the water discharge pipe member 50 is prevented from rotating randomly.

  As shown in FIG. 8, the movable joint 20 to which the water discharge pipe member 50 is attached while holding the faucet body 30 is attached to the fixed joint 10. That is, an operation of inserting the “insertion portion 20e protruding from the lower end of the support cylinder portion 51” into the insertion recess 13 opened above the base portion 80a is performed. This insertion operation is completed when the bottom surface of the large-diameter portion 20a of the movable joint 20 contacts the upper end surface of the fixed joint 10.

  At this time, the retaining groove 27 and the screw hole 13 f of the fixed joint 10 are aligned in the radial direction of the movable joint 20. For this reason, when the retaining screw M is screwed into the screw hole 13f, the distal end portion of the shaft portion M1 enters the retaining groove 27. Accordingly, the insertion portion 20e can be prevented from coming off from the insertion recess 13. In this state, the insertion portion 20e inserted into the insertion recess 13 can be rotated 360 degrees with reference to the axis (rotation axis J).

  However, when the screwing amount of the retaining screw M is increased and the tip portion of the shaft portion M1 is brought into contact with the bottom portion of the retaining groove 27, the insertion portion 20e is prevented from rotating in the insertion recess 13. That is, the retaining screw M functions as a stopper having a retaining function and a rotation preventing function for the insertion portion 20e.

  As described above, when the movable joint 20 is attached to the fixed joint 10, as shown in FIG. 8, the medium diameter portion 20b is inserted into the medium diameter space portion 13c, and the taper portion 20c is inserted into the large diameter space portion 13e. At the same time, the small diameter portion 20d is inserted into the small diameter space portion 13d. As a result, the primary end 21a of the hot water supply flow channel 21 and the secondary end 14d of the hot water flow channel 14a are disposed on the rotational axis J of the insertion portion 20e. While communicating up and down. For this reason, even if the insertion portion 20e is rotated 360 degrees around the rotation axis J, the hot water supply use flow path 21 and the hot water supply flow path 14a are always in communication.

  Further, when the movable joint 20 is attached to the fixed joint 10 in this way, as shown in FIGS. 8 and 9, the primary side end 22a of the water supply reaching flow path 22 and the water supply flow path 14b are connected. The secondary side end portion 14h communicates with the "inflow side communication space 20R formed in a state of circling the taper portion 20c". That is, the inflow side communication space 20R is constituted by an annular space portion 131e located around the taper portion 20c in the large diameter space portion 13e. The inflow side communication space 20R is formed in a state in which an annular path is drawn along the direction of turning around the outer surface of the insertion portion 20e (the direction of turning around the rotation axis J). 9A and 9B, even if the insertion portion 20e is rotated about the rotation axis J, the water supply reaching flow path 22 and the water supply flow path 14b are still on the inflow side. It always communicates via the communication space 20R. At this time, when the insertion portion 20e is rotated by a predetermined amount around the rotation axis J, the primary side end 22a of the water supply reaching channel 22 and the secondary side end of the water supply channel 14b 14h opposes along the radial direction of the insertion part 20e. Further, when the movable joint 20 is attached to the fixed joint 10, the primary end 22a of the water supply reaching flow path 22, the secondary end 14h of the water supply flow path 14b, and the second inflow side. The axial center position of the communication space 20R (the position along the axial center J direction of the insertion portion 20e) is aligned.

  The inflow-side communication space 20R is configured by inserting a tapered portion 20c that reduces the outer diameter downward into a large-diameter space portion 13e having an increased inner diameter. Therefore, since the cross section of the flow path of the inflow side communication space 20R is sufficiently large, the water flowing out from the water supply flow path 14b is smoothly guided toward the water supply reaching flow path 22.

  When the movable joint 20 is attached to the fixed joint 10, as shown in FIG. 8, the seal member P3 attached to the attachment groove 26c of the intermediate diameter portion 20b is “the inner wall of the intermediate diameter space portion 13c in the fixed joint 10. The seal member P4 that is in watertight contact with the “part constituting the portion” and is attached to the attachment groove 26d of the small diameter portion 20d is the “part of the fixed joint 10 that constitutes the inner wall portion of the small diameter space portion 13d”. Abuts in a watertight manner. For this reason, the watertightness between the “flow channel portion for hot water supply” and the “flow channel portion for water supply” is maintained.

  As described above, when the hot and cold water mixing faucet S is attached to the sink 80, the terminal portion 85H of the hot water supply main pipe H and the hot water supply hole (not shown) of the fixed disk 32a are connected to the hot water supply connecting pipe 5 and The hot water supply flow path 14a and the hot water supply arrival flow path 21 communicate with each other, and the terminal 85C of the original water supply pipe C and the water supply hole (not shown) of the fixed disk 32a are connected to the water supply pipe. 6 and the water supply flow path 14b and the water supply reaching flow path 22 are brought into communication. And these communication states are always maintained irrespective of the rotation position of the faucet main body 30 (insertion part 20e).

  The mounting device T of this embodiment is a movable joint that holds the faucet body 30 in an integrally rotatable state while being attached to the stationary joint 10 in a rotatable state, and the fixed joint 10 fixed to the base portion 80a. And a joint 20. Regardless of the rotational position of the movable joint 20 (insertion portion 20e), the hot water supply channel 14a and the hot water supply reaching channel 21 are in communication with each other, and the water supply channel 14b and the water supply reaching channel are connected. 22 is in communication.

  Therefore, according to the attachment device T of the present embodiment, as shown in FIGS. 10A and 10B, “the positional relationship between the terminal portion 85H of the hot water supply source pipe H and the hot water supply connection pipe 5”. The faucet body 30 can be rotated without changing the “positional relationship between the terminal portion 85C of the water supply main pipe C and the connection pipe 6 for water supply”. Here, FIG. 10 shows “a connecting pipe 5 for hot water supply (however, the upper end portion is shown) and a connecting pipe 6 for water supply (however, the upper end portion is shown)” and “a terminal portion of the main pipe H for hot water supply” It is a schematic top view which shows the positional relationship with 85H and the terminal part 85C of the main piping C for water supply. 10A shows a positional relationship before applying rotation to the faucet body 30, and FIG. 10B shows a positional relationship after applying rotation to the faucet body 30, 10 (a) and 10 (b), even if the faucet body 30 is rotated, “the positional relationship between the terminal portion 85H of the hot water supply source pipe H and the hot water supply connection pipe 5” and “ The “positional relationship between the terminal portion 85C of the water supply source pipe C and the water supply connection pipe 6” does not change.

  For this reason, the fixing joint 10 is fixed to the base portion 80a by “connecting the terminal portion 85H of the hot water supply original pipe H and the hot water supply flow path 14a using the hot water supply connection pipe 5 and What is necessary is just to carry out so that it may be in the "good state for connecting the terminal part 85C of the piping C and the water supply flow path 14b using the connection pipe 6 for water supply."

  Then, for example, after the faucet body 30 is supported by the fixed joint 10 via the movable joint 20, a desired rotation is applied to the faucet body 30, thereby “the lever for operating the sliding valve device 32. The handle 60 "can be directed in a desired direction. That is, in this embodiment, as shown in FIG. 1, the faucet body 30 is located obliquely forward to the right when viewed from the user G located in front of the center front of the water tank 82. The lever handle 60 is oriented in the direction of the user G by rotating about 45 degrees around the pivot axis (that is, the axis of the lever handle 60 is substantially oriented in the direction of the user G). )

  Thus, in the attachment device T of the present embodiment, the fixed joint 10 involved in the connection with the terminal portions of the original pipes H and C and the movable joint 20 involved in the connection with the faucet body 30 are separated. The movable joint 20 is rotatable with respect to the fixed joint 10. That is, according to the attachment device T of the present embodiment, the faucet body 30 can be rotated around the rotation axis J of the insertion portion 20e according to the state of the use space (kitchen D). The operation of attaching the faucet S to various attachment portions can be performed smoothly and reliably.

  In addition, the attachment apparatus T of a present Example functions effectively also when performing water pumping etc. using the hot-water mixed tap S. That is, as shown by a broken line in FIG. 1, even when a bucket 500 or the like is inserted into the water tank 82 and hot water is poured into the bucket 500 or the like from the hot water / mixing tap S, the faucet body 30 can be pivoted on its rotating shaft. The lever handle 60 and the water discharge pipe portion 52 can be removed from above the water tank 82 by rotating around the center (that is, around the rotation axis J of the insertion portion 20e) (reference numerals 60L and 52L in FIG. 1). See). In this case, the operation of taking out the bucket 500 or the like from the water tank 82 can be smoothly performed without being disturbed by the lever handle 60, the water discharge pipe portion 52, or the like.

  Further, according to the mounting device T of the present embodiment, the faucet body 30 can be rotated with the fixed joint 10 as a reference, so that it can appropriately cope with the situation of recently used spaces (mounting portions). Can do. For example, as in application example 1 shown in FIG. 11A, it is possible to accurately cope with the case where the sink 80 is disposed in a portion (for example, the central portion) other than the wall portion of the kitchen D.

  That is, a specific example in which the hot and cold water mixing faucet S is attached to the portion located between the right and left water tanks 81 and 82 in the base portion 80a of the sink 80 of the application example 1 is shown. Yes. In this application example 1, when the user G in the center front of the right water tank 82 uses the hot water mixing faucet S, the user G1 in the center rear of the left water tank 81 uses the hot water mixing faucet S. Also in this case, the lever handle 60 faces the direction of the user G, G1 by rotating the faucet body 30 around the pivot axis (that is, around the pivot axis J of the insertion portion 20e). (See lever handles labeled 60B and 60C).

  In the application example 1, even when the user G2 at the center rear side of the right water tank 82 uses the hot / cold water faucet S, the faucet body 30 is moved around its rotation axis (that is, the insertion portion 20e). The lever handle 60 can also be directed in the direction of the user G2 (see the lever handle denoted by reference numeral 60D).

  In this embodiment, after the faucet body 30 is rotated around the pivot axis (that is, around the pivot axis J of the insertion portion 20e) by a "desired angle", the retaining screw M When the screwing amount is increased and the tip of the shaft portion M1 is brought into contact with the bottom of the retaining groove 27, the rotational position of the faucet body 30 (the rotational position around the rotational axis J of the insertion portion 20e) is fixed. be able to.

  Moreover, according to the attachment device T of the present embodiment, the faucet body 30 can be rotated with reference to the fixed joint 10, so that hot water is smoothly supplied to other faucet-related devices adjacent to the attachment portion. be able to. For example, application example 2 shown in FIG. 11 (b) shows a specific example in which a tap faucet S is attached to the attachment portion E <b> 2 selected from the base portion E <b> 1 of the washstand E using the attachment device T. . The mounting portion E2 is located on the right side of the wash bowl E3 in the upper surface portion of the wash basin E (especially, it is desirable to be obliquely rearward to the right). And in this application example 2, the washing machine F is installed on the right side of the washstand E. However, the attachment portion E2 can be provided on the left side of the wash bowl E3 in the upper surface portion of the wash stand E, and the washing machine F can be installed on the left side of the wash stand E.

  According to this application example 2, the faucet body 30 is rotatable with respect to the fixed joint 10 so that hot water discharged from the hot / cold water faucet S (especially, “hot water” used for removing dirt) is desirable. .) Can be smoothly supplied to the washing machine F.

  Moreover, according to the attachment device T of the present embodiment, the faucet body 30 can be attached to and detached from the fixed joint 10, so that it is possible to quickly and accurately cope with the renovation of the use space.

  For example, as shown in application example 3 and application example 4 in FIGS. 12B and 12C, the hot and cold water mixing tap S may be replaced with another type of single lever hot and cold water mixing taps S3 and S4. it can. That is, by making the dimensions (external dimensions, internal dimensions, etc.) of the fixed joint 10 and the movable joint 20 used for “another faucet to be replaced” common, the water above the movable joint 20 is increased. It is possible to change the faucet to various specifications by exchanging the plug portion. Therefore, even if there is a sudden change in the faucet specifications after construction, it can be easily changed if it is not in use, and even during renovation, faucets of various specifications can be used without changing the piping. Can be selected freely. That is, renovation and the like can be performed smoothly by construction only on the upper side of the base portion 80a (that is, “upper construction”).

  Specifically, in this embodiment, as shown in FIG. 12A, a lever handle 60 is disposed on the upper part of the faucet body 30, and the currant (that is, the water discharge pipe portion 52) is attached to the faucet body 30. Although the aspect arrange | positioned below was illustrated, using the same attachment apparatus T, it can also attach to another type of single lever type hot and cold water mixing taps S3 and S4 to an attachment part (base part 80a). For example, as shown in application example 3 of FIG. 12B, a hot water / water mixing faucet S3 in which a currant (water discharge pipe portion 52) is protruded from the side of the faucet body 30 is attached, or as shown in FIG. As shown in the application example 4, the hot water / water mixing faucet S4 in which the currant (the water discharge pipe portion 52) protrudes from the upper portion of the faucet body 30 and the lever handle 60 is disposed on the side portion of the faucet body 30 may be attached. it can.

  In this embodiment, a single lever type hot and cold water mixing faucet is illustrated as the hot and cold water mixing tap S. However, the type of the hot and cold water mixing faucet to which the mounting device T of this embodiment is attached is a single lever type. For example, a thermostat type or a two-handle type may be used. Here, the application example 5 of FIG.13 and FIG.14 has shown the example of application to the 2 handle type hot-and-water mixing tap S5.

  The basic usage mode of the hot and cold water mixing tap S5 is the mode shown in FIG. That is, below the mounting portion (the base portion 80a), the terminal portion 85H of the main pipe H for hot water supply is disposed on the left side when viewed from the user, and the terminal of the main pipe C for water supply is disposed on the right side when viewed from the user. The portion 85C is disposed (hereinafter, this situation is referred to as “normal piping”). In the upper part of the faucet body 30A, a handle for adjusting the amount of hot water (hereinafter referred to as "hot water side handle") 65H is disposed on the left side when viewed from the user, and for adjusting the amount of water on the right side when viewed from the user. 65C (hereinafter referred to as “water-side handle”) 65C is disposed.

  Also in this application example 5, the direction of the faucet body 30A can be changed by rotating the faucet body 30A around the rotation axis J of the insertion portion 20e. That is, when the basic posture is such that the front portion 31A of the faucet body 30A faces the front front, the faucet body 30A is rotated about the rotation axis J of the insertion portion 20e of the faucet body 30A, and the front portion 31A is inclined forward. It can also be directed. In particular, as in the present embodiment, in the aspect in which the faucet body 30A is installed in a portion (oblique rear portion) located obliquely behind the water tank 82, the front portion 31A is disposed obliquely forward (the user at the center front of the water tank 82). Direction).

  In Application Example 5, as shown in FIG. 14, the faucet body 30A is rotated 180 degrees around the rotation axis J of the insertion portion 20e so that the hot water side handle 65H is located on the right side as viewed from the user. The water side handle 65C is disposed on the left side as viewed from the user. In this case, for example, it is suitable as a mixed water tap S5 for left-handed users. As described above, in the “two-handle type hot and cold water mixing faucet S5” to which the invention of each claim is applied, by rotating the faucet body 30A around the rotation axis J of the insertion portion 20e, the right side In addition, the positional relationship between the hot water handle 65H and the water handle 65C (left and right positional relationship as viewed from the user) can be selected according to the characteristics, preferences, requirements, etc. of each user.

  Depending on the situation of the usage space, the terminal portion 85H of the hot water supply main pipe H and the terminal portion 85C of the water supply main pipe C may be arranged in the left and right directions (hereinafter, this situation is referred to as “reverse”). "Piping"). However, according to the application example 5, even in such a case, the faucet body 30A can be appropriately dealt with by rotating 180 degrees around the rotation axis J of the insertion portion 20e. That is, when the faucet body 30A is rotated 180 degrees, the hot water side handle 65H is disposed on the left side when viewed from the user, and the water side handle is positioned on the right side when viewed from the user. 65C is disposed. However, in this case, the hot water connection pipe 5, the hot water supply flow path 14 a, and the hot water supply arrival flow path 21 are used for water supply, and the water supply connection pipe 6, the water supply flow path 14 b, and the water supply arrival flow are used. The path 22 is used for hot water supply. Further, the application example to the “reverse piping” is applicable not only to a two-handle type hot water / water mixing tap, but also to a single lever type or thermostat type hot water / water mixing tap.

  The scope of each invention is not limited to the specific modes shown in the above-described embodiments, and various modifications can be exemplified within the scope of each invention.

  Furthermore, in this embodiment, the movable joint 20 is prevented from being detached from the fixed joint 10 by the retaining groove 27 and the retaining screw M. However, the movable joint 20 may be prevented from being detached from the fixed joint 10 in place of the method using the retaining screw M or using another method together with the method using the retaining screw M. For example, as in Modification 1 shown in FIG. 15, the flange 20F for retaining the protrusion protrudes from the outer peripheral portion on the lower end side of the large diameter portion 20a, and the cylindrical portion 10T extends concentrically from the upper end portion of the fixed joint 10. Set up. And the external thread part 10M is provided in the outer peripheral part of the cylindrical part 10T.

  Further, the nut main body 10P having a female screw portion 10N that can be screwed to the male screw portion 10M, and the nut main body 10P from the axially inner side (portion where the female screw portion 10N is not formed) in the inner peripheral portion of the nut main body 10P. A retaining nut 10N having a presser portion 10R projecting in the radially inward direction is prepared. Then, the female screw portion 10N is screwed into the male screw portion 10M of the cylindrical portion 10T, and the flange 20F is sandwiched between the cylindrical portion 10T and the holding portion 10R, thereby preventing the movable joint 20 from coming off from the fixed joint 10. Can also be planned.

  Furthermore, although the specific example which attaches the hot / cold water mixing faucet S to the base part 80a was shown in the present Example, the invention of each claim can be used also when attaching a faucet to another attaching part. For example, as in the second modification shown in FIGS. 16 and 17, the attachment device T of the embodiment is also used when the same hot water / water mixing faucet S as that of the embodiment is attached to the wall portion (particularly, the wall surface panel) W. Can be used.

  In the second modification, the rotation axis J of the insertion portion 20e is oriented in the horizontal direction. Therefore, when an operation (rotation operation) for adjusting the temperature is performed with the lever handle 60, as shown in FIG. 17A, the lever handle 60 has a pendulum shape in the left and right direction (when viewed from the front of the lever handle 60). Will swing. For this reason, as shown in FIG. 17B, when an obstacle (other wall portion or the like) X exists on the side of the lever handle 60, the swinging lever handle 60 is There is a possibility of collision with X. However, in the second modification, the lever faucet body 30 is rotated about the rotation axis J of the insertion portion 20e, and the swing path of the lever handle 60 is changed to a state avoiding the obstacle X, whereby the lever A collision between the handle 60 and an obstacle (such as another wall) X can be avoided. Furthermore, in the second modification, the direction of the lever handle 60 can be changed to a direction that is easier to use for each user. For example, it is easy to install the lever handle 60 upward while the handle is installed downward.

  In the embodiment, as described above, since the faucet body 30 is detachable from the fixed joint 10, the hot and cold water mixing faucet S can be replaced with one having a branching faucet when renovating the use space. Further, in the mounting device T of the embodiment, the movable joint 20 can be exchanged when the usage space is reformed. For example, as shown in Modification 3 in FIG. 18, the movable joint 20 including the branch plugs 28a and 28b can be replaced.

  The movable joint 20 of the third modification includes a “hot water side branch plug 28 a” for branching the hot water supply reaching channel 21 and a “water side branch” for branching the hot water reaching channel 22. Plug 28b ". Then, for example, a dishwasher (or a dishwasher / dryer) is connected to the branch channel branched from the hot water supply reaching channel 21 via the hot water side branch plug 28a. The branch channel branched from the water supply reaching channel 22 via 28b is connected to a water purifier, for example. However, the branch plug provided in the movable joint 20 may be one of the “hot water side branch plug 28a” and the “water side branch plug 28b”.

  Moreover, in an Example, as shown in the modification 4 of FIGS. 19-21, the positioning means for positioning the rotation position of the faucet main body 30 (movable joint 20) may be added. In the fourth modification, as shown in FIG. 19, three engaging recesses 29 a, 29 b, 29 c are formed on the outer peripheral portion of the movable joint 20, and the engaging protrusion 13 T protrudes from the inner wall portion of the insertion recess 13. ing. The engaging recesses 29a, 29b, and 29c show specific examples of the engaging portion for restriction, and the engaging protrusion 13T has a specific example of the engaging portion for restriction.

  The engaging protrusion 13T is configured by using the ball B1 of the ball plunger B attached to the fixed joint 10. That is, as shown in FIG. 20, the ball plunger B is disposed in a bottomed cylindrical housing BH, urging means (coil spring) B2 accommodated in the housing BH, and an opening of the housing BH. And a ball B1. The ball B1 protrudes outside the housing BH by approximately a hemisphere, but when it receives pressure from the front of the opening of the housing BH, the ball B1 moves back into the housing BH against the urging force of the urging means B2. In addition, the amount of protrusion to the outside of the housing BH can be reduced.

  On the other hand, the movable joint 20 is formed with a recess 20H in which a part of the outer diameter along the circumferential direction is reduced in a step shape. The recess 20H and the engaging protrusion 13T can be aligned in the radial direction of the insertion portion 20e. That is, the recess 20H whose outer diameter is reduced is a position traced 45 degrees to the left and right along the rotation axis J with the portion located directly behind the lever handle 60 as the center. In the following description, “the engagement protrusion 13T in the movable joint 20 is a portion that can be aligned in the radial direction of the insertion portion 20e, except for the recess 20H”, that is, “the outer diameter is stepped. The portion that is not reduced is referred to as a normal portion 20J.

  An engagement recess (hereinafter referred to as “first engagement recess”) 29a is formed in the center of the recess 20H (that is, the position behind the lever handle 60), and one end of the recess 20H. The remaining one engaging recess (hereinafter referred to as “second engaging recess”) 29b is formed in one end portion along the rotation axis J along the direction of circling the insertion portion 20e. The other engaging recess (hereinafter referred to as “third engaging recess”) on the other end of the place 20H (the other end along the direction of the insertion portion 20e along the rotation axis J). ) 29c is formed. As shown in FIG. 20, in the second engaging recess 29b and the third engaging recess 29c, the edges 291b and 291c that are located away from the first engaging recess 29a are the side walls of the recess 20H. Units 20V and 20W are integrated.

  Since any of the engaging recesses 29a, 29b, and 29c can be aligned along the radial direction of the engaging projection 13T and the insertion portion 20e, the axis of the lever handle 60 is engaged with the position extended rearward. When the combining protrusion 13T (ball B1) exists, the engaging protrusion 13T (ball B1) is urged in the direction of the lever handle 60 by the urging means B2, and engages with the first engaging recess 29a. Hereinafter, the rotational position of the movable joint 20 (water faucet body 30) and the lever handle 60 at this time is referred to as a basic position.

  When the movable joint 20 (water faucet body 30) is in the basic position, as shown in FIG. 21A, the user rotates the lever handle 60 in one direction of rotation (the direction of arrow Y in the figure). Then, since the movable joint 20 (water faucet body 30) also rotates, the engaging protrusion 13T (ball B1) escapes from the first engaging recess 29a against the urging force of the urging means B2. At this time, a so-called “click feeling (notch feeling)” is transmitted to the user's hand.

  Then, as shown in FIG. 21A, when the rotation amount of the lever handle 60 reaches 45 degrees, the engaging protrusion 13T (ball B1) engages with the second left engaging recess 29b. At this time, since the so-called “click feeling (notch feeling)” is transmitted to the user's hand, the user has changed the rotation position of the lever handle 60 by 45 degrees (45 degrees in one rotation direction) from the basic position. In addition, the rotational position of the lever handle 60 is determined by the engagement between the engagement protrusion 13T (ball B1) and the second engagement recess 29b. Hereinafter, the rotational position of the movable joint 20 (water faucet body 30) and the lever handle 60 at this time is referred to as a first rotational position.

  Furthermore, as shown in FIG. 21B, when it is desired to increase the rotation amount of the lever handle 60 in one rotation direction, “when the lever handle 60 is changed from the basic position to the first rotation position”. It is necessary to apply a force larger than the “force applied to the lever handle 60” to the lever handle 60. In order to increase the rotation amount, it is necessary that the engaging protrusion 13T (ball B1) escapes from the recess 20H and reaches the outer peripheral portion of the normal portion 20J. At that time, the engagement protrusion 13T (ball B1) is moved in the radially outward direction of the movable joint 20 by an amount obtained by adding the “depth of the second left engagement recess 29a” and the “depth of the recess 20H”. That is, it is necessary to compress the biasing means B2 by an amount obtained by adding the “depth of the second left engaging recess 29a” and the “depth of the recess 20H”. is there.

  When the turning position of the lever handle 60 is returned to the basic position, the engaging protrusion 13T (ball B1) engages with the first engaging recess 29a, so that the turning position of the lever handle 60 is positioned at the basic position. At the same time, a so-called “click feeling (notch feeling)” is transmitted to the user's hand.

  Although illustration is omitted, when the user rotates the lever handle 60 in the other rotation direction when the position of the movable joint 20 (water faucet body 30) is the basic position, the rotation of the lever handle 60 is performed. When the amount becomes 45 degrees, the engagement protrusion 13T (ball B1) engages with the third left engagement recess 29c. At this time, the rotation position of the lever handle 60 (hereinafter referred to as “second rotation position”) is positioned, and at that time, a so-called “click feeling (notch feeling)” is transmitted to the user's hand. Further, when it is desired to increase the rotation amount of the lever handle 60 in the other rotation direction, it is more than “the force applied to the lever handle 60 when the lever handle 60 is changed from the basic position to the second rotation position”. It is necessary to apply a large force to the lever handle 60.

  In the fourth modification, the embodiment has been described in which the engagement recesses 29a, 29b, and 29c are directly provided in the movable joint 20. However, as in the modification 5 in FIG. The engagement portion forming member 290 is separately attached to the movable joint 20 using a method such as screwing.

  Further, in the embodiment, each application example, and each modification, the movable joint 20 (water faucet body 30) is illustrated as being capable of rotating 360 degrees around the rotation axis J of the insertion portion 20e. As shown in Modification 6 shown in a) and Modification 7 shown in FIG. 23 (b), the rotation amount by which the movable joint 20 (water faucet body 30) can be turned is set within a range of 360 degrees or less. it can. That is, the modification 6 shows a specific example in which the rotation amount is 90 degrees, and the modification 7 shows a specific example in which the rotation amount is 180 degrees.

  That is, a groove 600 having a central angle of 90 degrees is formed in the movable joint 20 of the modified example 6, and the ball plunger B attached to the fixed joint 10 is inserted into the groove 600. In addition, a groove 610 having a central angle of 180 degrees is formed in the movable joint 20 of Modification Example 7, and a ball plunger B attached to the fixed joint 10 is inserted into the groove 610. And in the modification 6 and the modification 7, it is in the range until the housing BH of the ball plunger B contact | abuts to the side wall part of the groove | channels 600 and 610 (that is, the range which the housing BH can move in the groove | channels 600 and 610). The rotation range of the movable joint 20 (the faucet body 30) is restricted.

  Furthermore, in the examples, each application example, and each modification example, the application example to the hot and cold water mixing faucet (S, etc.) has been described. However, as shown in the modification example 8 in FIG. It can also be illustrated. Here, the attachment device T of the modification 8 is different from the embodiment in the following points. That is, in the fixed joint 10 of the modification 8, the flow path used as the hot water supply flow path 14a in the embodiment is used as the mixed water flow path 14A that allows the hot water whose temperature is adjusted in advance on the primary side of the fixed joint 10 to pass therethrough. In the embodiment, the flow path used as the water supply flow path 14b is used as the outflow flow path 14B. The mixed water channel 14A is another specific example of the “fluid supply channel” shown in claim 1. Moreover, in the modification 8, the connection pipe | tube 5A for mixed water for connecting with the terminal part of mixed water supply piping and the mixed water flow path 14A is used.

  Further, in the movable joint 20 of the modified example 8, the hot water outflow passage 23 in the movable joint 20 of the embodiment is excluded, and the flow passage used as the hot water supply reaching passage 21 in the movable joint 20 of the embodiment is used. The channel used as the mixed water reaching channel 21A and used as the water supply reaching channel 22 in the movable joint 20 of the embodiment is used as the passing channel 22A. The mixed water reaching channel 21A is another specific example of the “arriving channel” shown in claim 1. Moreover, in the modification 8, 6 A of communication piping for connecting the outflow flow path 14B and the water discharging means (a currant, a shower head, etc.) are used. Further, in the mounting device of the modified example 8, the flow path used as the inflow side communication space 20R in the embodiment is used as an “outflow side communication flow path (not shown)” constituting a specific example of the invention of claim 3. .

  In other words, the faucet body (not shown) held by the movable joint 20 of Modification 8 incorporates a valve device for selecting stop water and selecting the stop amount. The mixed water supplied to the faucet body after passing through the connecting pipe 5A for mixed water, the mixed water flow path 14A, and the mixed water arrival flow path 21A in this order is operated by an operation unit attached to the faucet body. Depending on the situation, it will flow out of the faucet body. The mixed water flowing out from the faucet body passes through the hot water supply reaching channel 21, the “outflow side communication channel (not shown)”, and the outflow channel 14B in this order, and further, the communication pipe 6A. The water is discharged from the water discharging means.

  In the invention of each claim, as shown in Modification 9 of FIG. 25 (a), the position of the bottom 13a of the insertion recess 13 of the fixed joint 10 is eccentric from the rotational axis J of the insertion portion 20e. Alternatively, the secondary end 141B of the second fluid supply channel 14B may be opened.
