[0008] One embodiment of the present invention, which is embodied in a pipe holder used for attaching a long water supply pipe to a building slab as a construction surface, will be described.

[0009] As shown in Figures 1 to 6, the pipe holder is formed by integrally molding a first holding member 11 and a second holding member 12 from synthetic resin. The pipe holder is fixed to the slab T using the first holding member 11 as a base.

[0010] The first retaining member 11 has a first retaining recess 13 having a semi-cylindrical inner surface. The first retaining recess 13 opens toward the side opposite to the slab T. The first retaining member 11 has a screw hole 14 that penetrates between the inner surface of the first retaining recess 13 and the outer surface on the slab T side. The pipe holder is fixed to the slab T via a screw (not shown) inserted through the screw hole 14.

[0011] The second retaining member 12 is a cover that covers the first retaining recess 13 of the first retaining member 11, and is made of a curved plate-like body. The second retaining member 12 has a second retaining recess 15 formed therein, which has a substantially semi-cylindrical inner surface. The second retaining recess 15 corresponds to the first retaining recess 13.

[0012] When the second retaining member 12 covers the opening of the first retaining recess 13 (see Figures 7 to 9), a substantially cylindrical retaining portion 16 is formed by the first retaining recess 13 and the second retaining recess 15 which opens toward the slab T side. The retaining portion 16 surrounds the outer circumference of the water supply pipes P1 to P3 in a substantially annular shape. The first retaining member 11 and the second retaining member 12 are connected at their respective first ends 11a and 12a via a thin-walled hinge 17, allowing the retaining portion 16 to be opened and closed.

[0013] As shown in FIGS. 2 and 5, on the inner surface of the first holding recess 13, a rib 18 is provided 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 is located at the center in the width direction of the first holding recess 13 (the front-back direction in FIG. 2 and the up-down direction in FIG. 5), and second ribs 18b that are short in the circumferential direction and are respectively located on both sides of the first rib 18a in the width direction. As shown in FIGS. 1 and 2, on the inner surface of the second holding recess 15 on the first end 12a side, a rib 19 that extends in the circumferential direction of the second holding recess 15 is provided.

[0014] When holding a water supply pipe (not shown) having an outer surface shape in which large-diameter portions and small-diameter portions are alternately provided in the axial direction, these ribs 18 and 19 enter into the small-diameter portion of the water supply pipe and restrict the movement of the water supply pipe in the axial direction by abutment.

[0015] 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.

[0016] As shown in FIGS. 7 to 9, the first holding member 11 and the second holding member 12 are engaged by the outward engaging claws 21a of the first engaging portion 21 and the inward engaging claws 22a of the second engaging portion 22 meshing with each other, and the holding portion 16 can be maintained in a closed state. The first holding member 11 and the second holding member 12 can hold water supply pipes P1 to P3 with different outer diameters by adjusting the inner diameter of the holding portion 16 by changing the engagement position of the second engaging portion 22 with respect to the first engaging portion 21.

[0017] 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. The pair of guide rails 25 are arranged at an interval and extend in parallel in a direction perpendicular to the slab T.

[0018] On the outer surface of the second end 12b of the second holding member 12, a guide projection 26 is provided. The guide projection 26 protrudes from the central portion in the width direction of the second holding recess 15 and extends in the circumferential direction of the second holding recess 15. The guide projection 26 has a space 26a formed therein with one side surface and the end surface opposite to the second end 12b being open in the circumferential direction of the second holding recess 15. That is, the guide projection 26 is connected to the outer surface of the second end 12b in the vicinity of the second engaging portion 22.

[0019] As shown in FIG. 2, when the second holding member 12 is rotated with respect to the first holding member 11 so that the second ends 11b and 12b approach each other from the state where the holding portion 16 is open, as shown in FIG. 9, the guide projection 26 of the second holding member 12 starts to enter between the pair of guide rails 25 of the first holding member 11.

[0020] As shown in FIGS. 7 and 8, when the rotation is further advanced to reduce the inner diameter of the holding portion 16, the second holding member 12 changes the engagement position of the second engaging portion 22 with respect to the first engaging portion 21 while the guide projection 26 is guided by the pair of guide rails 25. The guiding action of the guide projection 26 by the guide rails 25 prevents the engagement between the first engaging portion 21 and the second engaging portion 22 from coming off in the width direction, and the operation of reducing the inner diameter of the holding portion 16 can be stably performed. <0000'01> As shown in FIG. 2, at the second end 12b of the second holding member 12, a relief hole 28 penetrating between the inner surface and the outer surface of the second holding member 12 is formed on the side closer to the first end 11a than the second engaging portion 22 and the guide projection 26. The tip of the second end 11b of the first holding member 11 is convex so as to be insertable into the relief hole 28.

[0022] Therefore, as shown in Figures 7 and 8, when the second retaining member 12 is rotated relative to the first retaining member 11 and the inner diameter of the retaining portion 16 approaches its minimum, some of the outward-facing engaging claws 21a, which are located on the tip side of the first engaging portion 21, are inserted into the relief hole 28 of the second retaining member 12 from the inner surface side of the second retaining member 12. Furthermore, when the second retaining member 12 is rotated relative to the first retaining member 11, these outward-facing engaging claws 21a protrude from the outer surface of the second retaining member 12 through the relief hole 28, thereby allowing the inner diameter of the retaining portion 16 to continue to decrease toward its minimum.

[0023] In other words, the outward-facing engaging claw 21a at the tip of the first engaging portion 21 is used when the inner diameter of the holding portion 16 is near its maximum (see Figure 9), but not when the inner diameter of the holding portion 16 is near its minimum (see Figures 7 and 8). This unused outward-facing engaging claw 21a is designed to be released into the relief hole 28, and further out to the outside of the second holding member 12 via the relief hole 28.

[0024] In this way, compared to, for example, securing a space inside the second retaining member 12 to accommodate the unused outward-facing engaging claw 21a, it is not necessary to make the second retaining member 12 a shape that bulges outward to secure the space, and the pipe holder can be made smaller. In particular, the relief hole 28 is a through hole that allows the unused outward-facing engaging claw 21a to escape to the outside of the second retaining member 12, so it is even more effective in making the pipe holder smaller.

[0025] As shown in Figures 7 to 9, the outward-facing engaging claw 21a of the first engaging portion 21 and the inward-facing engaging claw 22a of the second engaging portion 22 have a unidirectional structure that allows relative movement in the direction of decreasing the inner diameter of the holding portion 16, but prevents relative movement in the direction of increasing the inner diameter of the holding portion 16. Therefore, the second holding member 12 cannot be simply rotated relative to the first holding member 11 in the direction of opening the holding portion 16 from a closed state.

[0026] In this case, the rotation operation is made possible by inserting the tip of a general-purpose tool (not shown), such as a flathead screwdriver, into the space 26a within the guide projection 26, and moving the tip of the tool so that the engaged first engaging portion 21 and the second engaging portion 22 are separated radially from each other in the direction of the water supply pipes P1 to P3.

[0027] The second retaining member 12 has a plate-shaped elastic tongue 31. The first end 31a of the elastic tongue 31 is connected to the inner surface of the second retaining recess 15. When the retaining portion 16 is closed, the second end 31b of the elastic tongue 31 can extend into the first retaining recess 13 of the first retaining member 11. The elastic tongue 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 retaining portion 16 with elastic force.

[0028] As shown in Figure 1, the first retaining member 11 is provided with a locking claw portion 35 on the inner surface of the first retaining recess 13. The locking claw portion 35 has a first locking claw 35a and a second locking claw 35b, which are provided along the circumferential direction of the first retaining recess 13. As shown in Figures 7 and 8, when the retaining portion 16 is closed, the second end 31b of the elastic tongue piece 31 abuts against and locks with the first locking claw 35a or the second locking claw 35b, thereby restricting the movement of the second end 31b of the elastic tongue piece 31 toward the second end 11b of the first retaining member 11.

[0029] When the elastic tongue 31, with its second end 31b in contact with and locked against the first or second locking claw 35a or 35b, is cantilevered at the first end 31a (see Figure 9), it changes to a double-supported state at both the first end 31a and the second end 31b. As a result, the elastic tongue 31 is prevented from deforming significantly radially outward from the water supply pipes P1 and P2. This leads to even more stable support of the water supply pipes P1 and P2.

[0030] Furthermore, the first locking claw 35a and the second locking claw 35b, like the ribs 18 and 19, are also used to fit into the small-diameter portion of the water supply pipe and restrict its axial movement by contacting it.

[0031] As shown in Figure 5, multiple (three in this embodiment) first locking claws 35a are provided in the width direction of the first retaining recess 13. As shown in Figure 7, the first locking claws 35a lock onto the second end 31b of the elastic tongue piece 31 when the pipe holder holds a water supply pipe P1 of the smallest outer diameter intended for use. Providing multiple first locking claws 35a leads to stable locking of the second end 31b of the elastic tongue piece 31.

[0032] The second locking claw 35b is provided at a distance from the central first locking claw 35a, on the second end 11b side of the first retaining member 11. As shown in Figure 8, the second locking claw 35b locks the second end 31b of the elastic tongue piece 31 when holding the water supply pipe P2 which has an outer diameter slightly larger than the minimum outer diameter.

[0033] As shown in Figure 9, when the elastic tongue 31 holds the water supply pipe P3 with its maximum outer diameter or an outer diameter close to its maximum outer diameter, it is not locked by the locking claw portion 35. This is because the water supply pipe P3 with its maximum outer diameter or an outer diameter close to its maximum outer diameter can contact the entire inner surface of the first retaining recess 13 and obtain sufficient support. In other words, the dimensions and shape of the inner surface of the first retaining recess 13 are set so that it contacts the water supply pipe P3 with its maximum outer diameter or an outer diameter close to its maximum outer diameter with minimal gaps.

[0034] As shown in Figure 1, a backup portion 39 is provided protruding from the inner surface of the second retaining recess 15 between the relief hole 28 and the elastic tongue 31. The backup portion 39 has a concave curved backup surface 39a that follows the back surface of the elastic tongue 31. The first end 31a of the elastic tongue 31 is joined to the base end of the backup portion 39 and can be said to be connected to the inner surface of the second retaining recess 15 via the base end.

[0035] As shown in Figure 9, the backup section 39 functions when holding the water supply pipe P3 with an outer diameter of the maximum or near-maximum outer diameter. Specifically, the back surface 39a contacts and supports the back surface of the elastic tongue 31, which has been significantly elastically deformed toward the inner surface of the second holding recess 15. This leads to improved durability of the elastic tongue 31 and further stable holding of the water supply pipe P3.

[0036] <Another example> The above embodiment can also be modified as follows, for example. ○By opening the other side of the guide projection 26, the space 26a is also opened in that portion. In other words, the guide projection 26 is made to resemble a leaf spring, cantilevered at the end located on the second end 12b side of the second holding member 12. Furthermore, a knob 41 is provided on the end edge (free end of the leaf spring) on ​​the first end 12a side of the guide projection 26.

[0037] In this case, by pulling the gripping portion 41, the first engaging portion 21 and the second engaging portion 22 can be separated, and the second holding member 12 can be rotated relative to the first holding member 11 in a direction that increases the inner diameter of the holding portion 16.

[0038] Furthermore, by making the guide projection 26 like a leaf spring, the guide projection 26 can be used as part of the gripping portion 41. Therefore, the operating force input to the gripping portion 41 can be concentrated near the second engaging portion 22 via the guide projection 26, making it even easier to separate the first engaging portion 21 and the second engaging portion 22.

[0039] ○ The relief hole 28 should not penetrate all the way through to the outer surface of the second retaining member 12, but should be a relief hole. In other words, in order to achieve the effect of providing relief for the unused outward-facing engaging claw 21a as described above, it is sufficient that the inner surface of the second retaining member 12 is recessed.

[0040] Other areas where work can be done include the vehicle body.

[0041] Other types of pipes include drainage pipes and gas pipes. Other long items besides pipes include wire harnesses and optical fibers.
