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

As shown in FIGS. 1 to 6, the pipe holder includes a first holding member 11 and a second holding member 12 integrally formed of 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. As shown in FIG. 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 screws (not shown) inserted through 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 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, A substantially cylindrical holding portion 16 is formed. The holding portion 16 surrounds the outer peripheries of the water supply pipes P1 to P3 in a substantially annular shape. First ends 11a and 12a of the first holding member 11 and the second holding member 12 are connected to each other through a thin hinge 17 so that the holding portion 16 can be opened and closed.

As shown in FIGS. 2 and 5 , ribs 18 are provided on the inner surface of the first holding recess 13 on the first end 11 a side with respect to the opening of the screw hole 14 . The rib 18 includes a first rib 18a elongated in the circumferential direction of the first holding recessed portion 13 and positioned at the center of the first holding recessed portion 13 in the width direction (the front and back direction in FIG. 2 and the vertical direction in FIG. 5). It consists of the 2nd rib 18b short in the said circumferential direction which is each located in the both sides of the said width direction with respect to the 1st 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 side of the first end 12a.

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 the small diameter portion of the water supply pipe, It abuts and regulates 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 11 b 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 12 b 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 arranged such that the outward engaging claw 21a of the first engaging portion 21 and the inward engaging claw of the second engaging portion 22 are connected to each other. 22a are engaged with each other, and the holding portion 16 can be maintained in a closed state. By changing the engaging position of the second engaging portion 22 with respect to the first engaging portion 21, the first holding member 11 and the second holding member 12 can adjust the inner diameter of the holding portion 16 to have different outer diameters. of 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 spaced apart and extend 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 protrusion 26 protrudes from the widthwise central portion of the second holding recess 15 and extends in the circumferential direction of the second holding recess 15 . The guide projection 26 has one side surface and 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 therein. That is, the guide protrusion 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.

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 opened, the state shown in FIG. As shown, the guide protrusion 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 projections 26 by the pair of guide rails 25 and moves toward the first position. The engagement position of the second engagement portion 22 with respect to the engagement portion 21 is changed. The guiding action of the guide projections 26 by the guide rails 25 prevents the engagement between the first engaging portion 21 and the second engaging portion 22 from being disengaged in the width direction, thereby reducing the inner diameter of the holding portion 16. can be stably performed.

As shown in FIG. 2 , at the second end 12 b of the second holding member 12 , the inner surface and the outer surface of the second holding member 12 are located closer to the first end 11 a than the second engaging portion 22 and the guide protrusion 26 . A relief hole 28 is formed penetrating between the . The tip of the second end 11 b of the first holding member 11 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, the plurality of outward engaging claws Some of the outward engaging claws 21a positioned on the distal end side of the first engaging portion 21 out of 21a are inserted into escape holes 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 with respect 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, thereby continuing to hold. It is permissible to reduce the inner diameter of the portion 16 to a minimum.

That is, the outward engaging claw 21a on the distal end 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 is used when the inner diameter of the holding portion 16 is near the minimum (see FIG. 7). and FIG. 8) are not used. The outward engaging claw 21a in the unused state is allowed to escape to the inside of the relief hole 28 and to the outside of the second holding member 12 via the relief hole 28. As shown in FIG.

In this way, the second holding member 12 can be arranged to secure the space, for example, compared to the case where the space for accommodating the outward engaging claw 21a in the unused state is secured inside the second holding member 12 . It is not necessary to have a shape that bulges outward greatly, and the size of the pipe holder can be reduced. In particular, the release hole 28 is a through hole for releasing the outward engaging claw 21a in the unused state to the outside of the second holding member 12, so that the size reduction of the pipe holder is more effective.

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 move in the direction of decreasing the inner diameter of the holding portion 16. relative movement is permitted, and relative movement in the direction in which the inner diameter of the holding portion 16 is increased is blocked. 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 slotted 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 with each other are supplied with water. By moving the tip of the tool away from the pipes P1 to P3 in the radial direction, the turning operation is enabled.

The second holding member 12 has a plate-like 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 . A second end 31 b 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 closed. The elastic tongue piece 31 presses the outer surface of the water supply pipes P1 to P3 held by the holding portion 16 with an elastic force, thereby stabilizing the holding of the water supply pipes P1 to P3.

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 recessed portion 13 . The locking claw portion 35 has a first locking claw 35 a and a second locking claw 35 b provided along the circumferential direction of the first holding recessed portion 13 . As shown in FIGS. 7 and 8, when the holding portion 16 is closed, the second end 31b of the elastic tongue piece 31 abuts and is locked by the first locking claw 35a or the second locking claw 35b. Thus, the movement of the second end 31b of the elastic tongue piece 31 toward the second end 11b of the first holding member 11 is restricted.

The elastic tongue piece 31, whose second end 31b abuts and is locked by the first locking claw 35a or the second locking claw 35b, shifts from the cantilevered state at the first end 31a (see FIG. 9) to the first end Both ends 31a and 31b are supported. Therefore, the elastic tongue piece 31 is restrained from largely deforming radially outward of the water supply pipes P1 and P2. This leads to further stable holding of the water supply pipes P1 and P2.

Like the ribs 18 and 19, the first locking claws 35a and the second locking claws 35b also enter into the small-diameter portion of the water supply pipe to abut and restrict the 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 claw 35a locks the second end 31b of the elastic tongue 31 when the pipe holder holds the water supply pipe P1 with the smallest 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 spaced apart 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.

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, which has the maximum outer diameter or an outer diameter close to the maximum outer diameter, abuts on the entire inner surface of the first holding recess 13 and can be sufficiently supported. That is, the dimensions and shape of the inner surface of the first holding recess 13 are set so as to abut against 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 protrudes 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 concavely curved backup surface 39 a along the back surface of the elastic tongue piece 31 . The first end 31a of the elastic tongue piece 31 joins 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 portion 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 that has been largely 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 improved durability of the elastic tongue piece 31 and more stable holding of the water supply pipe P3.

<Extra example>
It should be noted that the above embodiment can be modified, for example, as follows.
o By opening the other side surface of the guide convex portion 26, the space 26a can be opened for that portion as well. In other words, the guide protrusion 26 is formed like a leaf spring that is cantilevered at the end located on the second end 12b side of the second holding member 12 . A knob portion 41 is provided on the edge of the guide convex portion 26 on the side of the first end 12a (a leaf spring-like free end).

In this case, by pulling the knob 41 , the first engaging portion 21 and the second engaging portion 22 can be separated from each other, so that the inner diameter of the holding portion 16 is increased to increase the second position relative to the first holding member 11 . The holding member 12 can be rotated.

By making the guide projection 26 like a leaf spring, the guide projection 26 can be used as a part of the knob 41 . Therefore, the operating force input to the knob portion 41 can be concentrated in 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 are separated. The separation work becomes easier.

o The relief hole 28 should be a relief hole without penetrating to the outer surface of the second holding member 12 . In other words, at least the inner surface of the second holding member 12 should be recessed in order to achieve the effect of releasing the unused outward engaging claws 21a as described above.

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

○Other pipes include drainage pipes and gas pipes. Wire harnesses, optical fibers, and the like are examples of elongated bodies other than pipes.
