  An embodiment of the present invention, which 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, in the pipe holder, the first holding member 11 and the second holding member 12 are integrally molded using a synthetic resin as a material. The pipe holder is fixed to the slab T with the first holding member 11 as a base.

  The 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. The first holding member 11 is formed with a screw hole 14 penetrating 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.

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

  With the second holding member 12 covering 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 can be connected to each other via the 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 side of the first end 11 a with respect to the opening of the screw hole 14. The rib 18 is a first rib 18a which is long in the circumferential direction of the first holding recess 13 and is located at the center of the first holding recess 13 in the width direction (the front and back direction of FIG. 2 and the vertical direction of FIG. It consists of a second rib 18b short in the circumferential direction which is located on both sides in the width direction with respect to the one rib 18a. 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 12 a side.

  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, the ribs 18 and 19 enter the small diameter portion of the water supply pipe and The contact movement of the water supply pipe in the axial direction is restricted.

  As shown in FIG. 2, a first engaging portion 21 is provided at the second end 11 b of the first holding member 11. The first engagement portion 21 has a plurality of outward engagement claws 21 a provided on the outer surface of the second end 11 b in the circumferential direction of the first holding recess 13. A second engaging portion 22 is provided at the second end 12 b of the second holding member 12. The second engagement portion 22 has a plurality of inward engagement 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 the outward engagement claws 21 a of the first engagement portion 21 and the inward engagement claws of the second engagement portion 22. By engaging with 22a, the holding portion 16 can be maintained in the closed state. The first holding member 11 and the second holding member 12 adjust 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, and the outer diameters are different. Water supply pipes P1 to P3 can be held.

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

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

  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 11 b and 12 b approach each other from the state where the holding portion 16 is opened, FIG. As shown, the guide convex portion 26 of the second holding member 12 starts 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 portion 16, the second holding member 12 is guided along the guide convex portion 26 by the pair of guide rails 25. The engagement position of the second engagement portion 22 with respect to the engagement portion 21 is changed. By the guide action of the guide convex portion 26 by the guide rail 25, the engagement between the first engagement portion 21 and the second engagement portion 22 is prevented from being disengaged in the width direction, and the operation to reduce the inner diameter of the holding portion 16 Stable.

  As shown in FIG. 2, on the second end 12 b of the second holding member 12, on the side closer to the first end 11 a than the second engaging portion 22 and the guide convex portion 26, the inner surface and the outer surface of the second holding member 12 A relief hole 28 is formed through the space. The tip end of the second end 11 b of the first holding member 11 is convexly insertable into the escape 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 portion 16 approaches the minimum, the plurality of outward engaging claws Of 21a, a part of the outward engaging claws 21a positioned on the tip end side of the first engaging portion 21 is inserted from the inner surface side of the second holding member 12 with respect to the relief hole 28 of the second holding member 12 Be done. Furthermore, when the second holding member 12 is rotated with respect to the first holding member 11, the outward engaging claw 21a is protruded from the outer surface of the second holding member 12 through the escape hole 28, and thus, the holding is continued. It is acceptable to reduce the inner diameter of the portion 16 to the minimum.

  That is, although the outward engaging claw 21a on the tip end side in the first engaging portion 21 is used when the inner diameter of the holding portion 16 is near the maximum (see FIG. 9), the inner diameter of the holding portion 16 is near the minimum (FIG. 7) And not shown in FIG. The outward engagement claw 21a in the non-use state is released to the outside of the second holding member 12 in the release hole 28 and further through the release hole 28.

  In this way, for example, the second holding member 12 is secured to ensure the space, as compared with the case where the space for housing the outward engaging claw 21a in the non-use state is secured inside the second holding member 12, for example. There is no need to make the shape of the pipe bulging outward, and the pipe holder can be miniaturized. In particular, since the escape hole 28 is a through hole for escaping the outward engaging claw 21 a in the unused state to the outside of the second holding member 12, the pipe holder can be effectively miniaturized.

  As shown in FIGS. 7 to 9, the outward engagement claws 21 a of the first engagement portion 21 and the inward engagement claws 22 a of the second engagement portion 22 are in the direction of reducing the inner diameter of the holding portion 16. Relative movement is permitted, and relative movement in the direction of increasing the inner diameter of the holding portion 16 is blocked. Therefore, the second holding member 12 can not simply be rotated with respect to the first holding member 11 in the direction in which the holding portion 16 is opened from the state where the holding portion 16 is closed.

  In this case, the tip of a general-purpose tool (not shown) such as a flat-blade screwdriver is inserted into the space 26a in the guide convex portion 26 and the first engaging portion 21 and the second engaging portion 22 engaged are supplied with water. The turning operation is enabled by moving the tip of the tool so as to be separated in the radial direction of the pipes P1 to P3.

  The second holding member 12 has a plate-like elastic tongue 31. The elastic tongue 31 has a first end 31 a connected to the inner surface of the second holding recess 15. The second end 31 b of the elastic tongue 31 can extend into the first holding recess 13 of the first holding member 11 with the holding portion 16 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 by elastic force.

  As shown in FIG. 1, in the first holding member 11, the locking claw portion 35 is provided on the inner surface of the first holding recess 13. The locking claw portion 35 includes a first locking claw 35 a and a second locking claw 35 b provided along the circumferential direction of the first holding recess 13. As shown in FIGS. 7 and 8, the second end 31b of the elastic tongue piece 31 abuts on and is locked by the first locking claw 35a or the second locking claw 35b in a state where the holding portion 16 is closed. Thus, the movement of the second end 31 b of the elastic tongue 31 toward the second end 11 b of the first holding member 11 is restricted.

  The elastic tongue piece 31 in which the second end 31b abuts on and is engaged with the first locking claw 35a or the second locking claw 35b is a first end from the cantilevered state (see FIG. 9) at the first end 31a. 31a and the second end 31b are in a double-held state. Therefore, it is suppressed that the elastic tongue 31 is largely deformed outward in the radial direction of the water supply pipes P1, P2. This leads to further stable holding of the water supply pipes P1, P2.

  The first locking claws 35a and the second locking claws 35b enter the small diameter portion of the water supply pipe in the same manner as the ribs 18 and 19 so as to abut the movement of the water supply pipe in the axial direction. Used.

  As shown in FIG. 5, a plurality (three in the present embodiment) of the first locking claws 35 a are provided in the width direction of the first holding recess 13. As shown in FIG. 7, the first locking claw 35 a locks the second end 31 b of the elastic tongue 31 when the pipe holder holds the water supply pipe P <b> 1 of the smallest outer diameter assumed to be used. Providing a plurality of first locking claws 35 a leads to stable locking of the second end 31 b of the elastic tongue 31.

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

  As shown in FIG. 9, when the elastic tongue piece 31 holds the water supply pipe P3 having the maximum outside diameter or the outside diameter close to the maximum outside diameter, the elastic tongue piece 31 does not receive the locking by the locking claw portion 35. This is because the water supply pipe P3 having an outer diameter close to the maximum outer diameter or the maximum outer diameter abuts on the entire inner surface of the first holding recess 13 to obtain sufficient support. That is, the dimension and shape of the inner surface of the first holding recess 13 are set so as to abut the water supply pipe P3 having an outer diameter close to the maximum outer diameter or the maximum outer diameter with a small gap.

  As shown in FIG. 1, a backup portion 39 is provided in a protruding manner between the escape hole 28 and the elastic tongue piece 31 on the inner surface of the second holding recess 15. The backup portion 39 has a concave curved backup surface 39 a along the back surface of the elastic tongue 31. It can be said that the first end 31 a of the elastic tongue piece 31 is joined to the proximal end of the backup portion 39 and is connected to the inner surface of the second holding recess 15 through the proximal end.

  As shown in FIG. 9, the backup unit 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 elastically deformed to the inner surface side of the second holding recess 15 is abutted and supported by the backup surface 39a. This leads to the improvement of the durability of the elastic tongue 31 and the further stable holding of the water supply pipe P3.

<Another example>
In addition, the said embodiment can also be changed as follows, for example.
Opening the other side surface of the guide convex portion 26 to open the space 26a even in the corresponding portion. That is, the guide convex portion 26 should be like a flat spring cantilevered at an end portion located on the second end 12 b side of the second holding member 12. Then, the knob portion 41 is provided at an end edge (a free end like a leaf spring) of the guide convex portion 26 on the first end 12 a side.

  In this case, by pulling the knob 41, the first engagement portion 21 and the second engagement portion 22 can be separated, and the second holding portion 11 is moved in the direction of increasing the inner diameter of the holding portion 16 relative to the first holding member 11. The holding member 12 can be turned.

  In addition, the guide convex part 26 can be utilized as a part of knob | pick part 41 by making the guide convex part 26 like a leaf | plate spring. Therefore, the operation force input to the knob 41 can be concentrated on the vicinity of the second engaging portion 22 through the guide convex portion 26 to act on the first engaging portion 21 and the second engaging portion 22. The separation operation is further facilitated.

  ○ The relief hole 28 as a relief recess should be a relief hole without penetrating to the outer surface of the second holding member 12. That is, at least the inner surface of the second holding member 12 may be recessed in order to obtain the effect of releasing the unused outward engaging claw 21a as described above.

  ○ Other construction surfaces include the body surface of the vehicle.

  ○ Other pipes include drainage pipes and gas pipes. Moreover, as a long body other than a pipe, a wire harness, an optical fiber, etc. are mentioned.
