The state which moved to the direction A which leaves | separates from the nut member 31, in other words, the expanded state is shown. The stop cock 30 is shipped in the state shown in FIG. 4, and is installed and used in the state shown in FIGS. 5 and 6 as necessary.

  As shown in these drawings, the nut member 31 is configured such that an outer surface 41 which is a part of the outer peripheral surface thereof is accommodated in the water stopcock body 32, and two O-rings 42 are provided on the outer surface 41. It has.

  The two O-rings 42 are provided in consideration of twisting when assembling the stop cock 30 by fitting the stop cock body 32 to the nut member 31 as will be described later. Even if twisted, water leakage prevention is ensured. The same applies to O-rings 57 and 59 described later.

  The stop cock main body 32 includes a main body 52 fitted with the outer surface 41 on the inner surface 51 which is a part of the inner peripheral surface 43 having a substantially cylindrical shape, and a C ring 65 as an annular member fitted to the inner surface 51. The water stop valve body 53 inserted from the end of the main body 52 opposite to the inner surface 51, the hard rubber valve seat packing 54 fitted to the end face of the water stop valve body 53, and the valve seat packing 54 A bolt 55 and a nut 56 for fixing to the water stop valve body 53 are provided.

  The water faucet body 32 is also provided with two O-rings 57 fitted to the peripheral surface of the water stop valve body 53, a spindle 58 screwed in such a manner that one end thereof is fitted inside the water stop valve body 53, a spindle 58 and two O-rings 59 fitted to the peripheral surface on the other end side.

  The water stopcock body 32 also includes a spindle guide 60 in which the water stop valve 53 and the spindle 58 are rotatably fitted in a state where the spindle 58 is inserted, and a washer 61 interposed between the spindle 58 and the spindle guide 60. , A retaining ring 62 in which the spindle 58 is positioned on the spindle guide 60 in the direction A, a handle 63 as an operating body located at an end of the main body 52 opposite to the inner surface 51, and the handle 63 are fixed to the spindle guide 60. A truss machine screw 64.

  The water stopcock body 32 also has a tubular connection portion 46 to which the connection pipe 14 is attached, and an inner peripheral surface 47 formed in the connection portion 46 so as to communicate with the inner peripheral surface 43. The connecting portion 46 protrudes in a direction perpendicular to the direction A. The inner peripheral surfaces 43 and 47 constitute a water supply path that leads from the water supply pipe 11 to the connection pipe 14.

  As shown in FIG. 8, the stop cock 30 includes a retaining means 70 that prevents the stop cock body 32 from being detached from the nut member 31. In FIG. 8, the code | symbol 66 has shown the latching groove | channel which is recessedly provided in the inner surface 51 and forms the 2nd step part 74 mentioned later.

  In FIG. 8, the C ring 65 is indicated by an imaginary line. As will be described later, the C ring 65 is fitted into the locking groove 66 by attaching the water stopcock body 32 to the nut member 31. For this reason, such a virtual line indicates the C-ring 65 in a mounted state.

  The retaining means 70 includes a protrusion 71 projecting from the outer surface 41 of the nut member 31 so as to have a predetermined width w1 in the direction AB in which the water faucet body 32 advances and retreats with respect to the nut member 31, and a direction AB. , The recess 72 is recessed in the inner surface 51 of the water stopcock body 32 so as to have a width w2 larger than the width w1 of the protrusion 71. Thus, the width w1 of the convex portion 71 is smaller than the width w2 of the concave portion 72.

  The concave portion 72 is located on the upstream side of the first step portion 73 in the direction A and on the upstream side in the same direction on the downstream side in the direction A, and the convex portion 71 on the upstream side in the same direction. And a second stepped portion 74 having a smaller diameter.

  The convex portion 71 has entered the concave portion 72 and is movable between the first step portion 73 and the second step portion 74 and faces the concave portion 72 over the moving range.

  The second step 74 is formed by a C-ring 65 fixed to the inner surface 51 in the locking groove 66. For this reason, the thickness of the C-ring 65 is larger than the depth of the locking groove 66, and the thickness of the C ring 65 is in contact with the convex portion 71 in the portion exposed from the locking groove 66.

  An end of the inner surface 51 on the upstream side in the direction A is a tapered portion 78 that expands toward the upstream side in the direction A.

  The convex portion 71 includes a first step 75 having a small diameter on the downstream side in the direction A, and a second step having a small diameter on the upstream side in the same direction and located on the upstream side of the first step 75 in the direction A. And a stepped portion 76.

  The nut member 31 has a groove portion 77 located on the outer surface 41 on the upstream side of the convex portion 71 in the direction A. The groove part 77 is located upstream of the second step part 76 in the direction A. The diameter of the nut member 31 in the groove part 77 is smaller than the diameter of the nut member 31 in the second step part 76.

  The C-ring 65 is a metal member having a substantially circular shape but having a notch in a part thereof, and having elasticity in a direction to expand when the diameter is the diameter of the locking groove 66.

  The nut member 31 is fixed to the joint 15 by fitting the joint 15 to the inner peripheral surface 45 thereof.

  When assembling the stop cock 30 having such a configuration, when the nut member 31 and the stop cock main body 32 are integrated, the nut member 31 and the stop member are fitted in the state where the C ring 65 is loosely fitted in the groove 77 and accommodated. The faucet body 32 is moved relatively.

  Specifically, the stop cock main body 32 is moved to move in the direction B relative to the nut member 31, or the nut member 31 is moved in the direction A relative to the stop cock main body 32. The nut member 31 is inserted into the stop cock main body 32, and these are fitted to each other.

  At this time, the C ring 65 is urged by the taper portion 78 in a direction in which the diameter decreases, and enters the inner surface 51. When the nut member 31 is further moved in the direction A, the C-ring 65 is fitted into the locking groove 66 due to the elasticity in the expanding direction, and is mounted and fixed in a state of being fitted into the locking groove 66.

  Thereby, the water faucet body 32 is prohibited from moving the second stepped portion 74 upstream of the convex portion 71 in the direction A. In other words, the nut member 31 is prohibited from moving the convex portion 71 to the upstream side in the direction A from the second stepped portion 74. The convex portion 71 is allowed to move in the concave portion 72 by the length w2-w1 in the direction AB. The water faucet body 32 is restricted from relative movement with respect to the nut member 31 by the convex portion 71.

  In this way, the water faucet body 32 accommodates the outer surface 41 of the nut member 31 on the inner surface 51, and allows the convex portion 71 to move only between the first step portion 73 and the second step portion 74. By allowing, the nut member 31 is supported by the stroke of length w2-w1 in a stepless and smoothly movable manner. Moreover, since the inner surface 51 and the outer surface 41 form a circumferential surface, the nut member 31 and the water faucet body 32 are relatively rotatable around an axis along the direction AB.

  In the water stop cock 30 having such a configuration, a water supply path that leads from the water supply pipe 11 to the connection pipe 14 is constituted by the inner peripheral surfaces 43, 44, and 47.

  When the handle 63 is turned, the spindle 58 rotates integrally, and the water stop valve body 53 screwed to the spindle 58 is displaced in the direction AB. At this time, the communication state between the inner peripheral surface 45 and the inner peripheral surfaces 43 and 47 is changed by the valve seat packing 54.

  By such an operation, the handle 63 is configured to open and close the water supply path by driving the water stop valve body 53 by a turning operation. The handle 63 rotates at a fixed position during the rotation operation, and the water stop cock 30 is a so-called non-rising stop cock. Therefore, as the installation space of the stop cock 30, it is sufficient to secure at least a relative movement range between the nut member 31 and the stop cock body 32, and the installation work and the water supply amount adjustment work can be easily performed even in a narrow space. Yes.

  The joint 15 is a tubular member and allows water to pass through the inner peripheral surface 44 thereof. The inner circumferential surface 45 allows water to pass through the nut member 31 attached to the joint 15 and the inner circumferential surfaces 44 and 45 communicating with each other. The inner peripheral surfaces 44 and 45 together with the inner peripheral surfaces 43 and 47 constitute a water supply path that leads from the water supply pipe 11 to the connection pipe 14.

  The connecting pipe 14 has a cap nut 48 that is screwed into the connecting portion 46 at the tip. The main body of the connecting pipe 14 is made of a highly rigid material. This is because the toilet 10 has a built-in warm water washing device, and therefore the load due to the water pressure applied to the connecting pipe 14 during water supply is large, so that this load can be endured.

  The inner peripheral surface 49 of the cap nut 48 has a tapered portion 50 that expands toward the stop cock body 32 side. Therefore, when the cap nut 48 is to be screwed into the connection portion 46, the cap nut 48 can be smoothly fitted into the connection portion 46, and then can be shifted to the screwing operation. When the cap nut 48 is screwed into the connecting portion 46 and fastened, the connecting pipe 14 is fixed to the stop cock main body 32, and the gap between the stop cock 30 and the connecting pipe 14 becomes watertight, thereby preventing water leakage.

  Therefore, the connection pipe 14 is easily fixed even in a narrow space. The connecting pipe 14 is made of a material having high rigidity because the toilet 10 is a built-in warm water washing device, so that it is difficult to bend, but the stopcock body 32 has a high degree of freedom of movement. Therefore, the fixing work of the connecting pipe 14 is easy. Moreover, since the stop cock main body 32 is prevented from being detached from the nut member 31 by the retaining means 70, the installation work can be performed with confidence.

  In the toilet device 100 and the toilet water supply device 20 configured as described above, the water stopcock 30 assembled by integrating the nut member 31 and the stopcock main body 32 after the water supply pipe 11 is installed is provided. The toilet 10 with the cover 12 not attached is installed at a predetermined position on the floor.

  The other end of the connecting pipe 14 having one end connected to the toilet 10 side is fixed to the stop cock body 32 by a cap nut 48. At this time, the stop cock main body 32 is appropriately slid or rotated in the direction AB with respect to the nut member 31 as necessary from the state shown in FIG. By adopting the state shown in FIG. 6, an easy-to-connect position to the connection pipe 14 is obtained.

  After the connection pipe 14 is fixed, the handle 63 is rotated to adjust the open / close state of the class water channel so that an appropriate amount of water is supplied to the toilet bowl 10. The cover 12 is attached and the toilet water supply device 20 is concealed in the concealing unit 13.

  The stop cock 30 has a direction AB substantially similar to the fact that the connecting pipe 14 extends laterally from the toilet 10 and the connecting portion 46 projects in a direction perpendicular to the direction AB. It is installed in a direction that extends in the vertical direction.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to such specific embodiments, and various modifications and changes can be made within the scope of the gist of the present invention described in the claims. It can be changed.

  For example, the configuration of the toilet water supply device 20 can be changed according to the installation form of the water supply pipe 11. In the above embodiment, the water supply pipe 11 is installed on the floor surface. However, when the water supply pipe 11 is installed on the wall surface as shown in FIGS. 9 to 11, as shown in FIG. The faucet 30 is attached upside down from the above configuration. FIG. 9 is a view corresponding to FIG. 2 and shows a state in which the cover 12 is removed as in FIG. 10 and 11 correspond to FIGS. 4 and 5, respectively.

  Also in this case, the stop cock 30 is installed so that the direction AB extends in a substantially vertical direction for the reason described above. Along with this, the joint 15 has an L-shape, and one end projects vertically from the wall surface and the other end extends in a substantially vertical direction.

  Even when the water supply pipe 11 is installed on the wall surface, depending on the installation position of the water supply pipe 11, such as when the installation position is close to the floor surface, the stop cock 30 is installed in the same manner as the above embodiment. There are things to do.

  In the form shown in FIGS. 9 to 11, the stroke in the direction AB of the water stopcock body 32 with respect to the nut member 31 is longer than that in the above-described form. Thus, the stroke can be changed by changing the widths w1 and w2 as necessary.

  In addition, when the relative rotation between the nut member 31 and the water faucet body 32 is unnecessary or when it is desired to prohibit the relative rotation, the outer surface 41 of the nut member 31 and the inner surface 51 of the water faucet body 32 are other than the circumferential surface. It can be a shape.

  The annular member is not limited to the C-ring, and may be an annular packing or the like formed of rubber or the like as long as it can prevent removal. The locking groove is not limited to an annular shape as long as an annular member can be fitted and attached to the water faucet body.
