An embodiment of the present invention embodied in a pipe holder used for attaching a water supply pipe as a long body 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 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 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 to 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 through the screw hole 14.

The second holding member 12 is a lid body 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.

In a 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 are formed. 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 open and close the holding portion 16 by connecting the first ends 11a and 12a of each other via a thin hinge 17.

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

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

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 on the outer surface of the second end 11b in the circumferential direction of the first holding recess 13. 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 on the inner surface of the second end 12b in the circumferential direction of the second holding recess 15.

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. The holding portion 16 can be maintained in a closed state by engaging with the 22a by engaging with the 22a. The first holding member 11 and the second holding member 12 adjust the inner diameter of the holding portion 16 by changing the engaging position of the second engaging portion 22 with respect to the first engaging portion 21, and have different outer diameters. 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 on 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 intervals and extend parallel to the slab T in the direction perpendicular to the direction.

A guide convex portion 26 is provided on the outer surface of the second end 12b of the second holding member 12. The guide convex portion 26 projects 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. In the guide convex portion 26, one side surface and the end surface on the side opposite to the second end 12b are opened 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 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, FIG. 9 shows. As shown, the guide convex portion 26 of the second holding member 12 starts approaching 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 in order to reduce the inner diameter of the holding portion 16, the second holding member 12 is guided by the pair of guide rails 25 while guiding the guide convex portion 26 to the first. The engagement position of the second engaging portion 22 with respect to the engaging portion 21 is changed. An operation of reducing the inner diameter of the holding portion 16 by preventing the engagement between the first engaging portion 21 and the second engaging portion 22 from being disengaged in the width direction by the guiding action of the guide convex portion 26 by the guide rail 25. Can be performed stably.

As shown in FIG. 2, in the second end 12b of the second holding member 12, the inner surface and the outer surface of the second holding member 12 are located on the first end 11a side of the second engaging portion 22 and the guide convex portion 26. A relief hole 28 penetrating between the holes 28 is formed. In the first holding member 11, the tip of the second end 11b has a convex shape so that it can be inserted into the relief hole 28.

Therefore, as shown in FIGS. 7 and 8, when the second holding member 12 is rotated with respect to the first holding member 11 and the inner diameter of the holding portion 16 approaches the minimum, a plurality of outward engaging claws are used. Of the 21a, a part of the outward engaging claws 21a located on the tip end side of the first engaging portion 21 is inserted into the relief hole 28 of the second holding member 12 from the inner surface side of the second holding member 12. Will be done. Further, when the second holding member 12 is rotated with respect 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, and thus is continuously held. It is permissible to reduce the inner diameter of the portion 16 toward the minimum.

That is, the outward engaging claw 21a on the tip side of the first engaging portion 21 is used when the inner diameter of the holding portion 16 is near the maximum (see FIG. 9), but the inner diameter of the holding portion 16 is near the minimum (FIG. 7). And see FIG. 8). The outward engaging claw 21a in the unused state is released to the inside of the relief hole 28 and further to the outside of the second holding member 12 through the relief hole 28.

By doing so, for example, as compared with the 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 is secured in order to secure the space. It is not necessary to make the shape of the pipe bulge outward, and the pipe holder can be miniaturized. In particular, since the relief hole 28 is a through hole that allows the outward engaging claw 21a in an unused state to escape to the outside of the second holding member 12, it is effective to reduce 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 directed toward reducing the inner diameter of the holding portion 16. It is a unidirectional structure that allows relative movement of the holding portion 16 and 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 with respect to the first holding member 11 in the direction in which the holding portion 16 is opened from the state in which 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 that are engaged are supplied with water. By moving the tip of the tool so as to be separated in the radial direction of the pipes P1 to P3, the rotation operation is possible.

The second holding member 12 has a plate-shaped elastic tongue piece 31. The elastic tongue piece 31 has a first end 31a connected to the inner surface of the second holding recess 15. In the elastic tongue piece 31, the second end 31b can extend into the first holding recess 13 of the first holding member 11 in a state where the holding portion 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 by the 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. 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, with the holding portion 16 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. As a result, the movement of the second end 31b of the elastic tongue piece 31 to the second end 11b side of the first holding member 11 is restricted.

The elastic tongue piece 31 in which the second end 31b is in contact with the first locking claw 35a or the second locking claw 35b and is locked is the first end from the cantilever state at the first end 31a (see FIG. 9). It is in a double-sided state at 31a and the second end 31b. Therefore, it is possible to prevent the elastic tongue piece 31 from being significantly deformed outward in the radial direction of the water supply pipes P1 and P2. This leads to further stable maintenance of the water supply pipes P1 and P2.

The first locking claw 35a and the second locking claw 35b, like the ribs 18 and 19, also enter the small diameter portion of the water supply pipe to restrict the movement of the water supply pipe in the axial direction. Used.

As shown in FIG. 5, a plurality of (three in the present 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 claw 35a locks the second end 31b of the elastic tongue piece 31 when the pipe holder holds the water supply pipe P1 having the minimum outer diameter assumed to be used. Providing a plurality of first locking claws 35a leads to stable locking of the second end 31b of the elastic tongue piece 31.

The second locking claw 35b is provided at a distance on the second end 11b side of the first holding member 11 with respect to the central first locking claw 35a. 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 comes into contact with the entire inner surface of the first holding recess 13 to obtain sufficient support. That is, the dimensional shape of the inner surface of the first holding recess 13 is set so as to come into contact with the water supply pipe P3 having the maximum outer diameter or an outer diameter close to the maximum outer diameter with a small gap.

As shown in FIG. 1, a backup portion 39 is provided so as to project 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 concave curved backup surface 39a along the back surface of the elastic tongue piece 31. It can be said that the first end 31a of the elastic tongue piece 31 joins the base end portion of the backup portion 39 and is connected to the inner surface of the second holding recess 15 via the base end portion.

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, which is greatly elastically deformed toward the inner surface side of the second holding recess 15, is abutted and supported by the backup surface 39a. This leads to an improvement in the durability of the elastic tongue piece 31 and a further stable holding of the water supply pipe P3.

<Another example>
The above embodiment can be changed as follows, for example.
〇 By opening the other side surface of the guide convex portion 26, the space 26a is opened even in that portion. That is, the guide convex portion 26 is shaped like a leaf spring that is cantilevered and supported by an end portion located on the second end 12b side of the second holding member 12. Then, a knob portion 41 is provided at the end edge (leaf spring-like free end) on the first end 12a side of the guide convex portion 26.

In this case, by pulling the knob portion 41, the first engaging portion 21 and the second engaging portion 22 can be separated from each other, and the inner diameter of the holding portion 16 is increased in the direction of increasing the inner diameter of the holding portion 16. The holding member 12 can be rotated.

By making the guide convex portion 26 like a leaf spring, the guide convex portion 26 can be used as a part of the knob portion 41. Therefore, the operating force input to the knob portion 41 can be concentrated on the vicinity of the second engaging portion 22 via the guide convex portion 26, and the first engaging portion 21 and the second engaging portion 22 can be brought into contact with each other. The work of separating them becomes easier.

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

○ Other construction surfaces include the vehicle body surface.

○ Other pipes include drainage pipes and gas pipes. Further, examples of a long body other than a pipe include a wire harness and an optical fiber.
