FIG. 4 is an explanatory view of a state in which the connector 7 is locked to the saddle joint 5 and the saddle joint fixture 6. FIG. 5 is an explanatory view of a state in which the fastener 8 is locked to the saddle joint 5 and the saddle joint fixture 6. FIG. 6 is an explanatory view of a state in which the handle 55 is removed from the fastener 8. Hereinafter, the connection operation of connecting the water tap 3 to the water distribution pipe 2 using the saddle joint unit 10 will be described with reference to FIGS. 1 and 4 to 6.

  In the connection operation, first, the saddle joint 5 to which the water tap 3 is connected is placed on the water distribution pipe 2. That is, the connection pipe portion 22 of the saddle joint 5 and the perforation 4 of the water distribution pipe 2 are stacked, and the concavely curved lower surface of the saddle main body portion 21 is placed on the outer peripheral surface of the water distribution pipe 2. Next, the saddle joint fixture 6 is disposed on the opposite side of the water distribution pipe 2 from the saddle joint 5, and the concavely curved upper surface of the fixing tool main body 31 is brought into contact with the outer peripheral surface of the water distribution pipe 2.

  Then, as shown in FIG. 4, the connector first locking member 42 of the connector 7 is locked to the first joint side flange portion 23 of the saddle joint 5, and the connector second locking member 43 of the connector 7. Is locked to the first fixture side flange portion 33 of the saddle joint fixture 6. That is, the coupler shaft member 41 of the coupler 7 is inserted into the notches 25 and 35 from the tip end side of the first joint side flange portion 23 and the first fixture side flange portion 33, and the coupler first engagement is performed. The first joint side flange portion 23 and the first fixing tool side flange portion 33 are positioned between the stop member 42 and the connector second locking member 43. Then, the connector first locking member 42 is locked to the upper surface 23 a of the first joint side flange portion 23, and the connector second locking member 43 is locked to the lower surface 33 a of the first fixture side flange portion 33. . More specifically, the connector first locking member 42 is locked to the opening edge of the circular opening 25a of the notch 25 of the first joint side flange portion 23, and the connector second locking member 43 is (1) Lock the opening edge of the circular opening portion 35 a of the notch 35 of the fixing tool side flange portion 33. Thus, the connecting member 7 bridged between the first joint side flange portion 23 and the first fixture side flange portion 33 is the upper surface 23 a of the first joint side flange portion 23 and the first fixture side flange portion. A distance between the lower surface 33a of 33 and the predetermined distance D or more is prevented.

  After that, as shown in FIG. 5, the fastener first locking member 52 of the fastener 8 is locked to the second joint side flange portion 24 of the saddle joint 5, and the fastener second locking member 53 is used as a saddle joint The second fixing tool side flange portion 34 of the fixing tool 6 is locked. More specifically, first, the handle 55 is operated to rotate the cam 54 of the fastener 8 to place it in the open position 54B, and the first cam surface portion 65a is made to face the fastener first locking member 52. To Thereafter, the fastener shaft member 51 is inserted into the notches 25 and 35 from the tip end side of the second joint side flange portion 24 and the second fixture side flange portion 34, and the fastener first locking member 52 The second joint side flange portion 24 and the second fixture side flange portion 34 are positioned between the fastener second locking member 53. Thereby, the fastener first locking member 52 is disposed above the opening edge Z1 of the circular opening 25a of the notch 25 of the first joint side flange portion 23, and the fastener second locking member 53 is It arrange | positions below the opening edge Z2 of the circular opening part 35a of the notch part 35 of the fixing tool side flange part 33. As shown in FIG.

  Here, when the first cam surface portion 65a is made to face the fastener first locking member 52 and the first cam surface portion 65a and the fastener first locking member 52 are brought into contact with each other, the fastener first The distance F between the locking member 52 and the fastener second locking member 53 is longer than the predetermined distance D. Therefore, it is easy to position the second joint flange 24 and the second fixing flange 34 between the fastener first locking member 52 and the fastener second locking member 53.

  Next, the handle 55 is operated to rotate the cam 54 of the fastener 8 so that the second cam surface portion 65 b faces the fastener first locking member 52. The state in which the second cam surface portion 65b of the cam 54 is opposed to the fastener first locking member 52 is the state shown in FIG.

Here, the second distance D2 between the second cam surface portion 65b and the rotation axis L1 is longer than the first distance D1 between the first cam surface portion 65a and the rotation axis L1, and the second cam surface portion 65b Is projected to the outer peripheral side than the first cam surface portion 65a. Therefore, when the cam 54 is rotated to make the second cam surface portion 65b face the fastener first locking member 52, as shown by the arrow in FIG.
5 contacts the fastener first locking member 52 to move the fastener first locking member 52 to the side of the fastener second locking member 53. And in the state where the 2nd cam surface part 65b and the fastener first locking member 52 abut, the distance between the fastener first locking member 52 and the fastener second locking member 53 is predetermined. Or slightly smaller than the predetermined distance D. Therefore, the saddle joint 5 and the saddle joint fixture 6 hold the water distribution pipe 2 from both sides in the vertical direction Z. Accordingly, the saddle joint 5 is fastened to the water distribution pipe 2. Thus, the water tap 3 is connected to the water distribution pipe 2.

  Thereafter, as shown in FIG. 6, the lock pin 75 is caused to penetrate through the through holes 68 provided in the pair of cam plates 61 and 62 of the cam 54 to cause the lock mechanism 56 to function. Also, the handle 55 is removed from the cam 54.

  In this example, the fastener 8 is engaged with the saddle joint 5 and the saddle joint fixing tool 6 so that the rotation axis L1 of the cam 54 extends in the left-right direction X. The posture may be made such that the rotational axis L1 of the cam 54 is directed in the left-right direction X by locking the saddle joint 5 and the saddle joint fixing tool 6 by rotating the rotation axis L1 of the cam 54 by 90 °. In this case, when fastening the saddle joint 5 to the water distribution pipe 2, the handle 55 is operated in the front-rear direction Y along the water distribution pipe 2.

  Further, the fastener 8 is engaged with the first joint side flange portion 23 and the first fixing side flange portion 33, and the coupling is engaged with the second joint side flange portion 24 and the second fixing side flange portion 34. Of course, it may be stopped.

  Furthermore, the long hole 32 provided in the fixing tool main body 31 of the saddle joint fixing tool 6 can be omitted.

(Action effect)
According to this embodiment, the first fastener lock member 52 is locked to the saddle joint 5 and the second fastener lock member 53 is locked to the saddle joint fixture 6, and then the cam 54 is rotated. Then, when the second cam surface portion 65b is made to abut on the fastener first locking member 52, the saddle joint 5 and the saddle joint fixing tool 6 hold the water pipe 2 therebetween. Therefore, the saddle joint 5 can be fastened to the water distribution pipe 2 without using a bolt and a nut. As a result, since it is not necessary to fasten the bolt, it is possible to quickly perform a fastening operation of fastening the saddle joint 5 to the water distribution pipe 2.

  Further, the distance (tightening amount) in which the saddle joint 5 and the saddle joint fixing tool 6 approach when the cam 54 is rotated corresponds to the difference between the first distance D1 and the second distance D2. Therefore, it can be avoided that the tightening amount varies by the worker performing the construction, and the management of the construction becomes easy.

  Furthermore, even if it becomes necessary to release the fastening between the saddle joint 5 and the water distribution pipe 2 after the construction, the release is easy and the reuse of the fastener 8 is also easy. That is, if the cam 54 is rotated after construction so that the first cam surface portion 65a is in a posture to face the fastener first locking member 52, the fastener first locking member 52 and the fastener second locking member The distance between them and 53 is separated to a distance F longer than a predetermined distance D. Accordingly, the fastener 8 can be easily removed from the saddle joint 5 and the saddle joint fixture 6. Moreover, since the fastener 8 is not damaged at the time of releasing the fastening, reuse of the fastener 8 is easy.

Further, in the present example, a handle 55 that protrudes in a direction orthogonal to the rotation direction of the cam 54 is detachably attached to the cam 54 of the fastener 8. If such a handle 55 is provided, it becomes easy to rotate the cam 54 about the rotation axis L1. Therefore, the fastening operation of fastening the saddle joint 5 to the water distribution pipe 2 is facilitated. Further, since the handle 55 is detachable, if the handle 55 is removed from the cam 54 after the fastening operation is completed, the handle 55 does not interfere with the surroundings after construction. Moreover, it can prevent that the fastening with the saddle joint 5 and the distributing pipe 2 is cancelled | released by operation of the handle 55 accidentally.

  Furthermore, in the present example, the cam 54 moves the first cam surface portion 65 a from the closed position 54 A where the second cam surface portion 65 b is in contact with the fastener second locking member 53 to the fastener second locking member 53. A locking mechanism 56 is provided that prevents rotation towards the opposite open position 54B. Therefore, if the cam 54 is locked by the lock mechanism 56, it is possible to prevent the engagement of the saddle joint 5 with the water distribution pipe 2 from being released unintentionally.

  In the above example, the upper surface 23a of the first joint side flange portion 23 of the saddle joint 5 and the upper surface 24a of the second joint side flange portion 24 are located on the same imaginary plane, but on the same imaginary plane It does not have to be located at Similarly, the lower surface 33a of the first fixture side flange portion 33 of the saddle joint fixture 6 and the lower surface 34a of the second fixture side flange portion 34 are located on the same virtual plane, but on the same virtual plane It does not have to be located at

  For example, when the water tap 1 with a saddle is fixed to the water distribution pipe 2, the first joint side flange portion 23 is inclined downward Z2 from the end edge of the left side X1 of the saddle main body 21 toward the left side X1. Thus, the upper surface 23a can be an inclined surface that inclines downward Z2 toward the end of the left side X1. Similarly, the second joint side flange portion 24 is inclined downward Z2 from the end edge of the right side X2 of the saddle main body portion 21 toward the right side X2, and the upper surface 24a is inclined downward Z2 toward the end of the right side X2 Can be inclined. And, in this case, the first fixture side flange portion 33 of the saddle joint fixture 6 is inclined in the downward Z2 direction from the end edge of the left side X1 of the saddle body 21 toward the left side X1, and the lower surface 33a thereof. Is an inclined surface that inclines downward Z2 toward the end of the left side X1. Similarly, the second fixture side flange portion 34 of the saddle joint fixture 6 is inclined in the downward Z2 direction from the end edge of the right side X2 of the saddle main body portion 21 toward the right side X2, and its lower surface 34a is the right side X2 It is an inclined surface that inclines downward Z2 toward the end.

  Even in this case, when the saddle joint 5 and the saddle joint fixing tool 6 are arranged so as to sandwich the water distribution pipe 2 in the vertical direction Z, the first joint side flange portion 23 and the first fixing tool side flange It can be made to oppose the part 33 at intervals in the up-down direction Z. Further, the second joint side flange portion 24 and the second fixture side flange portion 34 can be opposed to each other by opening a gap in the vertical direction Z. Furthermore, with the water distribution pipe 2 sandwiched between the saddle joint 5 and the saddle joint fixture 6, the upper surface 23a of the first joint side flange portion 23 and the lower surface 33a of the first fixture side flange portion 33 are parallel to each other. The upper surface 24a of the second joint flange 24 and the lower surface 34a of the second fixing flange 34 can be parallel to each other. In addition, the distance between the upper surface 23a of the first joint flange 23 and the lower surface 33a of the first fixing flange 33, and the upper surface 23a of the second coupling flange 24 and the first fixing flange The distance between the lower surface 33a and the lower surface 33a can be a predetermined distance D. Therefore, the saddle fitting 5 can be fastened to the water distribution pipe 2 by bridging the connector 7 and the fastener 8 between the saddle joint 5 and the saddle joint fixture 6.
