DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

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

[0009] 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 a slab T with the first holding member 11 as a base.

[0010] The first holding member 11 is formed with a first holding recess 13 having a semi-cylindrical inner surface. The first holding recess 13 opens toward the side opposite the slab T. The first holding member 11 is formed with a screw hole 14 that 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 a screw (not shown) inserted into the screw hole 14.

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

[0012] In a state in which the second retaining member 12 covers the opening of the first retaining recess 13 (see Figs. 7 to 9), the first retaining recess 13 and the second retaining recess 15 that opens toward the slab T side form a substantially cylindrical retaining portion 16. The retaining portion 16 surrounds the outer periphery of the water supply pipes P1 to P3 in a substantially annular shape. The first retaining member 11 and the second retaining member 12 have first ends 11a, 12a connected to each other via a thin-walled hinge 17, making it possible to open and close the retaining portion 16.

[0013] As shown in Figures 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 is composed of a first rib 18a that is long in the circumferential direction of the first holding recess 13 and is located in the center of the width direction of the first holding recess 13 (the front-to-back direction in Figure 2 and the up-to-down direction in Figure 5), and second ribs 18b that are short in the circumferential direction and located on both sides of the first rib 18a in the width direction. As shown in Figures 1 and 2, a rib 19 that extends 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.

[0014] When holding a water supply pipe (not shown) having an outer surface shape in which large and small diameter sections are alternately provided in the axial direction, these ribs 18, 19 enter the small diameter section of the water supply pipe and abut against it to restrict axial movement of the water supply pipe.

[0015] As shown in Fig. 2, a first engagement portion 21 is provided at the second end 11b of the first holding member 11. The first engagement portion 21 has a plurality of outward engagement claws 21a provided on the outer surface of the second end 11b in the circumferential direction of the first holding recess 13. A second engagement portion 22 is provided at the second end 12b of the second holding member 12. The second engagement portion 22 has a plurality of inward engagement claws 22a provided on the inner surface of the second end 12b in the circumferential direction of the second holding recess 15.

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

[0017] 1, 3, and 5, a pair of guide rails 25 is provided at the second end 11b of the first holding member 11 so as to surround the first engagement portion 21. The pair of guide rails 25 are spaced apart from each other and extend parallel to the slab T in a direction perpendicular to the slab T.

[0018] A guide protrusion 26 is provided on the outer surface of the second end 12b of the second holding member 12. The guide protrusion 26 protrudes from the center of the second holding recess 15 in the width direction and extends in the circumferential direction of the second holding recess 15. The guide protrusion 26 is open on one side surface and on the end surface opposite to the second end 12b in the circumferential direction of the second holding recess 15, forming a space 26a therein. In other words, the guide protrusion 26 is connected to the outer surface of the second end 12b in the vicinity of the second engagement portion 22.

[0019] As shown in Figure 2, when the second holding member 12 is rotated relative to the first holding member 11 from the open state of the holding portion 16 so that the second ends 11b, 12b approach each other, the guide protrusion 26 of the second holding member 12 begins to enter between a pair of guide rails 25 of the first holding member 11, as shown in Figure 9.

[0020] 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 engagement portion 22 with respect to the first engagement portion 21 while the guide protrusions 26 are guided by a pair of guide rails 25. The guiding action of the guide protrusions 26 by the guide rails 25 prevents the engagement between the first engagement portion 21 and the second engagement portion 22 from coming loose in the width direction, and the operation of reducing the inner diameter of the holding portion 16 can be stably performed.

[0021] 2, at the second end 12b of the second holding member 12, a relief hole 28 penetrating between the inner and outer surfaces of the second holding member 12 is formed on the first end 11a side of the second engagement portion 22 and the guide protrusion 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] 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 portion 16 approaches the minimum, some of the multiple outward engaging claws 21a located on the tip side of the first engaging portion 21 are inserted into the escape holes 28 of the second holding member 12 from the inner surface side of the second holding member 12. Furthermore, when the second holding member 12 is rotated relative to the first holding member 11, the outward engaging claws 21a protrude from the outer surface of the second holding member 12 through the escape holes 28, and therefore the inner diameter of the holding portion 16 is allowed to continue to decrease toward the minimum.

[0023] That is, the outward engagement claws 21a on the tip side of the first engagement portion 21 are used when the inner diameter of the holding portion 16 is near the maximum (see FIG. 9), but are not used when the inner diameter of the holding portion 16 is near the minimum (see FIGS. 7 and 8). The outward engagement claws 21a in this unused state are allowed to escape into the escape hole 28 and further to the outside of the second holding member 12 via the escape hole 28.

[0024] In this way, for example, compared to a case where a space for accommodating the outward engaging claws 21a in the unused state is secured inside the second holding member 12, there is no need to make the second holding member 12 bulge outwardly to secure the space, and the pipe holder can be made smaller. In particular, the escape hole 28 is a through hole that allows the outward engaging claws 21a in the unused state to escape to the outside of the second holding member 12, which is more effective in making the pipe holder smaller.

[0025] 7 to 9, the outward engaging claws 21a of the first engaging portion 21 and the inward engaging claws 22a of the second engaging portion 22 have a one-way structure that permits relative movement in a direction that reduces the inner diameter of the holding portion 16, but prevents relative movement in a direction that increases 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 a direction that opens the holding portion 16 from a state in which the holding portion 16 is closed.

[0026] In this case, the rotation operation is enabled by inserting the tip of a general-purpose tool (not shown) such as a flat-head screwdriver into the space 26a within the guide protrusion 26 and moving the tip of the tool so that the engaged first engagement portion 21 and second engagement portion 22 move apart radially of the water supply pipes P1 to P3.

[0027] The second holding member 12 has a plate-shaped elastic tongue 31. A first end 31a of the elastic tongue 31 is connected to the inner surface of the second holding recess 15. A second end 31b of the elastic tongue 31 can extend into the first holding recess 13 of the first holding member 11 when the holding portion 16 is in a closed state. The elastic tongue 31 uses its elastic force to press against the outer surfaces of the water supply pipes P1 to P3 held by the holding portion 16, thereby stably holding the water supply pipes P1 to P3.

[0028] 1, the first holding member 11 is provided with a locking claw portion 35 on the inner surface of the first holding recess 13. The locking claw portion 35 has a first locking claw 35a and a second locking claw 35b provided along the circumferential direction of the first holding recess 13. As shown in FIGS. 7 and 8, when the holding portion 16 is in a closed state, the second end 31b of the elastic tongue 31 abuts against and is locked by the first locking claw 35a or the second locking claw 35b, thereby restricting the second end 31b of the elastic tongue 31 from moving toward the second end 11b of the first holding member 11.

[0029] The elastic tongue 31, whose second end 31b abuts against and is locked by the first locking claw 35a or the second locking claw 35b, changes from a cantilevered state at the first end 31a (see FIG. 9) to a double-supported state at the first end 31a and the second end 31b. This prevents the elastic tongue 31 from significantly deforming radially outwardly of the water supply pipes P1, P2. This leads to even more stable holding of the water supply pipes P1, P2.

[0030] Like ribs 18, 19, first locking claw 35a and second locking claw 35b are also used to enter into the small diameter portion of the water supply pipe and abut against it to restrict axial movement of the water supply pipe.

[0031] As shown in Fig. 5, a plurality of first locking claws 35a (three in this embodiment) are provided in the width direction of the first holding recess 13. As shown in Fig. 7, the first locking claws 35a lock the second end 31b of the elastic tongue 31 when the pipe holder holds a water supply pipe P1 with the minimum outer diameter expected for use. Providing a plurality of first locking claws 35a leads to stable locking of the second end 31b of the elastic tongue 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 holding member 11. 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.

[0033] 9, when elastic tongue piece 31 holds water supply pipe P3 having a maximum outer diameter or an outer diameter close to the maximum outer diameter, it is not locked by locking claw portion 35. This is because water supply pipe P3 having a maximum outer diameter or an outer diameter close to the maximum outer diameter abuts against the entire inner surface of first holding recess 13 and can obtain sufficient support. In other words, the dimensions and shape of the inner surface of first holding recess 13 are set so that water supply pipe P3 having a maximum outer diameter or an outer diameter close to the maximum outer diameter abuts with little gap.

[0034] 1, a backup portion 39 is provided on 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 backup surface 39a having a concave curved shape that fits along the back surface of the elastic tongue 31. The first end 31a of the elastic tongue 31 joins 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] 9, backup portion 39 functions to hold water supply pipe P3 having a maximum outer diameter or an outer diameter close to the maximum outer diameter. That is, backup surface 39a abuts and supports the back surface of elastic tongue 31 that has been significantly elastically deformed toward the inner surface of second holding recess 15. This leads to improved durability of elastic tongue 31 and more stable holding of water supply pipe P3.

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

[0037] In this case, by pulling knob 41, first engagement portion 21 and second engagement portion 22 can be separated, and second holding member 12 can be rotated relative to first holding member 11 in a direction in which the inner diameter of holding portion 16 is increased.

[0038] In addition, by making the guide protrusion 26 like 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 and acted on the vicinity of the second engagement portion 22 via the guide protrusion 26, making it even easier to separate the first engagement portion 21 and the second engagement portion 22.

[0039] The escape hole 28 is formed as an escape hole without penetrating to the outer surface of the second holding member 12. In other words, in order to achieve the effect of allowing the unused outward engaging claws 21a to escape as described above, it is sufficient that at least the inner surface of the second holding member 12 is recessed.

[0040] Other application surfaces include the body surfaces of vehicles.

[0041] Other examples of the long pipes include drainage pipes, gas pipes, etc. Examples of the long objects other than pipes include wire harnesses, optical fibers, etc.
