An embodiment in which the present invention is embodied in a pipe holder used for attaching a long water supply pipe to a slab of a building as a construction surface will be described.

As shown in FIGS. 1 to 6, the pipe holder is formed by integrally molding a first holding member 11 and a second holding member 12 using synthetic resin. The pipe holder is fixed to the slab T using the first holding member 11 as a base.

A first holding recess 13 having a semi-cylindrical inner surface is formed in the first holding member 11 . The first holding recess 13 opens toward the side opposite to the slab T. A screw hole 14 is formed in the first holding member 11 and penetrates between the inner surface of the first holding recess 13 and the outer surface on the slab T side. The pipe holder is fixed to the slab T via screws (not shown) inserted into the screw holes 14.

The second holding member 12 is a lid that covers the first holding recess 13 of the first holding member 11, and is made of a curved plate. A second holding recess 15 having a substantially semicylindrical inner surface is formed in the second holding member 12 . The second holding recess 15 corresponds to the first holding recess 13 .

In the state where the second holding member 12 covers the opening of the first holding recess 13 (see FIGS. 7 to 9), the first holding recess 13 and the second holding recess 15 opening toward the slab T side, A substantially cylindrical holding portion 16 is formed. The holding portion 16 surrounds the outer circumferences of the water supply pipes P1 to P3 in a substantially annular shape. The first holding member 11 and the second holding member 12 are connected at their first ends 11a and 12a via a thin hinge 17, so that the holding portion 16 can be opened and closed.

As shown in FIGS. 2 and 5, a rib 18 is provided on the inner surface of the first holding recess 13 on the first end 11a side with respect to the opening of the screw hole 14. The rib 18 includes a first rib 18a that is long in the circumferential direction of the first holding recess 13 and a first rib 18a that is located at the center of the first holding recess 13 in the width direction (the front and back directions in FIG. 2 and the vertical direction in FIG. 5). The second rib 18b is short in the circumferential direction and is located on both sides of the first rib 18a in the width direction. As shown in FIGS. 1 and 2, a rib 19 extending in the circumferential direction of the second holding recess 15 is provided on the inner surface of the second holding recess 15 on the first end 12a side.

When holding a water supply pipe (not shown) having an outer surface shape in which large diameter parts and small diameter parts are provided alternately in the axial direction, these ribs 18 and 19 enter into the small diameter part of the water supply pipe and enter the water supply pipe. The contact restricts the movement of the water supply pipe in the axial direction.

As shown in FIG. 2, a first engaging portion 21 is provided at the second end 11b of the first holding member 11. The first engaging portion 21 has a plurality of outward engaging claws 21a provided in the circumferential direction of the first holding recess 13 on the outer surface of the second end 11b. A second engaging portion 22 is provided at the second end 12b of the second holding member 12. The second engaging portion 22 has a plurality of inward engaging claws 22a provided in the circumferential direction of the second holding recess 15 on the inner surface of the second end 12b.

As shown in FIGS. 7 to 9, the first holding member 11 and the second holding member 12 are an outward engaging claw 21a of the first engaging portion 21 and an inward engaging claw of the second engaging portion 22. 22a, the holding portion 16 can be maintained in a closed state. The first holding member 11 and the second holding member 12 have different outer diameters by adjusting the inner diameter of the holding part 16 by changing the engagement position of the second engaging part 22 with respect to the first engaging part 21. Water supply pipes P1 to P3 can be held.

As shown in FIGS. 1, 3, and 5, a pair of guide rails 25 are provided at the second end 11b of the first holding member 11 so as to surround the first engaging portion 21. As shown in FIGS. The pair of guide rails 25 are arranged at intervals and extend parallel to the slab T in the perpendicular direction.

A guide protrusion 26 is provided on the outer surface of the second end 12b of the second holding member 12. The guide convex portion 26 is provided in a protruding manner at the widthwise central portion of the second holding recess 15 and extends in the circumferential direction of the second holding recess 15 . The guide protrusion 26 is open at one side surface and at an end surface opposite to the second end 12b in the circumferential direction of the second holding recess 15, and a space 26a is formed inside. That is, the guide convex portion 26 is connected to the outer surface of the second end 12b in the vicinity of the second engaging portion 22.

As shown in FIG. 2, when the second holding member 12 is rotated relative to the first holding member 11 so that the second ends 11b and 12b approach each other from the open state of the holding part 16, the state shown in FIG. As shown, the guide protrusion 26 of the second holding member 12 begins to enter between the pair of guide rails 25 of the first holding member 11.

As shown in FIGS. 7 and 8, when the rotation is further advanced to reduce the inner diameter of the holding part 16, the second holding member 12 is guided by the guide convex part 26 by the pair of guide rails 25, The engagement position of the second engagement part 22 with respect to the engagement part 21 is changed. The guiding action of the guide convex portion 26 by the guide rail 25 prevents the first engaging portion 21 and the second engaging portion 22 from disengaging in the width direction, thereby reducing the inner diameter of the holding portion 16. can be performed stably.

As shown in FIG. 2, at the second end 12b of the second holding member 12, the inner and outer surfaces of the second holding member 12 are located closer to the first end 11a than the second engaging portion 22 and the guide convex portion 26. A relief hole 28 is formed passing through the space. The tip of the second end 11b of the first holding member 11 has a convex shape that can be inserted into the relief hole 28.

Therefore, as shown in FIGS. 7 and 8, when the second holding member 12 is rotated relative to the first holding member 11 and the inner diameter of the holding part 16 approaches the minimum, the plurality of outward engaging claws 21a, some of the outward engaging claws 21a located on the distal end side of the first engaging portion 21 are inserted into the relief hole 28 of the second holding member 12 from the inner surface side of the second holding member 12. be done. Further, when the second holding member 12 is rotated relative to the first holding member 11, the outward engaging claw 21a is projected from the outer surface of the second holding member 12 through the relief hole 28, so that the holding member 12 continues to be held. It is permissible to reduce the inner diameter of the portion 16 toward the minimum.

In other words, the outward engaging pawl 21a on the tip side of the first engaging part 21 is used when the inner diameter of the holding part 16 is around the maximum (see FIG. 9), but when the inner diameter of the holding part 16 is around the minimum (see FIG. and FIG. 8). This outward engaging claw 21a that is not in use is allowed to escape into the escape hole 28 and further to the outside of the second holding member 12 through the escape hole 28.

In this way, for example, compared to a case where a space for accommodating the outward engaging claw 21a in the unused state is secured inside the second holding member 12, the second holding member 12 There is no need to make the pipe holder have a shape that bulges outward, and the pipe holder can be made smaller. In particular, since the escape hole 28 is a through hole that allows the outward engaging claw 21a that is not in use to escape to the outside of the second holding member 12, it is more effective in reducing the size of the pipe holder.

As shown in FIGS. 7 to 9, the outward engaging claw 21a of the first engaging portion 21 and the inward engaging claw 22a of the second engaging portion 22 are arranged in a direction that reduces the inner diameter of the holding portion 16. It has a one-way structure that allows relative movement of the holding part 16 and prevents relative movement in the direction of increasing the inner diameter of the holding part 16. Therefore, the second holding member 12 cannot be simply rotated relative to the first holding member 11 from the state in which the holding portion 16 is closed to the direction in which the holding portion 16 is opened.

In this case, insert the tip of a general-purpose tool (not shown) such as a flathead screwdriver into the space 26a in the guide convex part 26, and the first engaging part 21 and the second engaging part 22 that are engaged with each other are connected to the water supply. The rotation operation is made possible by moving the tip of the tool so as to separate it in the radial direction of the pipes P1 to P3.

The second holding member 12 has a plate-shaped elastic tongue piece 31 . The elastic tongue piece 31 has a first end 31 a connected to the inner surface of the second holding recess 15 . The second end 31b of the elastic tongue piece 31 can extend into the first holding recess 13 of the first holding member 11 when the holding part 16 is closed. The elastic tongue piece 31 stabilizes the holding of the water supply pipes P1 to P3 by pressing the outer surfaces of the water supply pipes P1 to P3 held by the holding portion 16 with elastic force.

As shown in FIG. 1, the first holding member 11 is provided with a locking claw portion 35 on the inner surface of the first holding recess 13. As shown in FIG. The locking claw portion 35 includes a first locking claw 35a and a second locking claw 35b, which are provided along the circumferential direction of the first holding recess 13. As shown in FIGS. 7 and 8, when the holding part 16 is closed, the second end 31b of the elastic tongue piece 31 comes into contact with the first locking claw 35a or the second locking claw 35b and is locked. This restricts the movement of the second end 31b of the elastic tongue piece 31 toward the second end 11b of the first holding member 11.

The elastic tongue piece 31 whose second end 31b abuts and is locked with the first locking claw 35a or the second locking claw 35b changes from the cantilevered state at the first end 31a (see FIG. 9) to the first end. 31a and the second end 31b are held at both ends. Therefore, the elastic tongue piece 31 is suppressed from deforming significantly outward in the radial direction of the water supply pipes P1, P2. This leads to further stable maintenance of the water supply pipes P1 and P2.

Note that, like the ribs 18 and 19, the first locking claw 35a and the second locking claw 35b are also used to enter into the small diameter portion of the water supply pipe and contact and restrict movement of the water supply pipe in the axial direction. used.

As shown in FIG. 5, a plurality (three in this embodiment) of the first locking claws 35a are provided in the width direction of the first holding recess 13. As shown in FIG. 7, the first locking pawl 35a locks the second end 31b of the elastic tongue piece 31 when the pipe holder holds the water supply pipe P1 with the minimum outer diameter expected to be used. Providing a plurality of first locking claws 35a leads to stably locking the second end 31b of the elastic tongue piece 31.

The second locking pawl 35b is provided on the second end 11b side of the first holding member 11 at a distance from the first locking pawl 35a at the center. As shown in FIG. 8, the second locking claw 35b locks the second end 31b of the elastic tongue piece 31 when holding the water supply pipe P2 having an outer diameter slightly larger than the minimum outer diameter.

As shown in FIG. 9, the elastic tongue piece 31 is not locked by the locking claw portion 35 when holding the water supply pipe P3 having the maximum outer diameter or an outer diameter close to the maximum outer diameter. This is because the water supply pipe P3 having the maximum outer diameter or an outer diameter close to the maximum outer diameter can come into contact with the entire inner surface of the first holding recess 13 and obtain sufficient support. In other words, the dimensions and shape of the inner surface of the first holding recess 13 are set so that the first holding recess 13 comes into contact with the water supply pipe P3 having the maximum outer diameter or an outer diameter close to the maximum outer diameter with little clearance.

As shown in FIG. 1 , a backup portion 39 is provided protrudingly between the relief hole 28 and the elastic tongue piece 31 on the inner surface of the second holding recess 15 . The backup portion 39 has a concavely curved backup surface 39a along the back surface of the elastic tongue piece 31. The first end 31a of the elastic tongue piece 31 is joined to the base end portion of the backup portion 39, and can be said to be connected to the inner surface of the second holding recess 15 via the base end portion.

As shown in FIG. 9, the backup part 39 functions when holding the water supply pipe P3 having the maximum outer diameter or an outer diameter close to the maximum outer diameter. That is, the back surface of the elastic tongue piece 31, which is largely elastically deformed toward the inner surface of the second holding recess 15, is abutted and supported by the backup surface 39a. This leads to improved durability of the elastic tongue piece 31 and further stable holding of the water supply pipe P3.

<Another example>
Note that the above embodiment can also be modified as follows, for example.
By opening the other side of the guide convex portion 26, the space 26a is also opened in that portion. In other words, the guide convex portion 26 is shaped like a leaf spring supported by a cantilever at the end located on the second end 12b side of the second holding member 12. A knob 41 is provided on the edge of the guide convex portion 26 on the first end 12a side (a free end like a leaf spring).

In this case, by pulling the knob 41, the first engagement part 21 and the second engagement part 22 can be separated, and the second The holding member 12 can be rotated.

Note that by forming the guide protrusion 26 in the shape of a leaf spring, the guide protrusion 26 can be used as a part of the knob 41. Therefore, the operating force input to the knob 41 can be concentrated in the vicinity of the second engaging part 22 via the guide convex part 26, and the first engaging part 21 and the second engaging part 22 can be The work of separating them becomes easier.

- Make the relief hole 28 a relief hole without penetrating it to the outer surface of the second holding member 12. That is, in order to achieve the effect of releasing the unused outward engaging claws 21a as described above, at least the inner surface of the second holding member 12 needs to be recessed.
