The base 20, the first holding member 30 and the second holding member 40 are integrally molded from synthetic resin such as polypropylene. That is, the first holding member 30 and the second holding member 40 are connected to each other via the base 20 .

The base 20 includes a mounting portion 21 provided with a mounting hole 21a extending in the vertical direction in the center portion in the front, rear, left, and right directions, and a "<"-shaped first columnar portion erected on the right edge of the upper surface of the mounting portion 21. 22 , and a “<”-shaped second columnar portion 23 erected on the left edge of the upper surface of the mounting portion 21 . The base 20 is screwed to the construction surface S through the mounting holes 21 a of the mounting portion 21 . The bottom surface of the base 20 is provided with a sharp-pointed projection 20a that bites into the construction surface S to prevent the long body holder 10 from rotating when the screw is fastened.

A first hinge 22 a made of a thin hinge is provided at the tip of the first columnar portion 22 . A second hinge 23 a made of a thin hinge is provided at the tip of the second columnar portion 23 .

Each of the first holding member 30 and the second holding member 40 has a semi-cylindrical shape. The first holding member 30 has a first holding recess 11a. The second holding member 40 has a second holding recess 11b that forms the holding portion 11 that surrounds the outer periphery of the pipe 100 together with the first holding recess 11a. Between the first end 30a located on the upper side of the first holding member 30 and the first end 40a located on the upper side of the second holding member 40 facing the first end 30a, the holding portion 11 is provided. An inlet 11c is provided for inserting the pipe 100 .

The outer surface of the first holding member 30 in the middle between the upper first end 30a and the lower second end 30b is connected to the first columnar portion 22 via a first hinge 22a. The outer surface of the second holding member 40 is connected to the second columnar portion 23 via a second hinge 23a at an intermediate portion between the first end 40a on the upper side and the second end 40b on the lower side. The inlet 11 c of the holding portion 11 is positioned on the axis of the mounting hole 21 a of the mounting portion 21 . The lateral width of the inlet 11c is larger than the inner diameter of the mounting hole 21a.

On the outer surface of the first holding member 30 on the side of the first end 30a, a plurality of (nine in this embodiment) outward engaging claws 31 are provided at predetermined intervals along the circumferential direction. A finger hook 32 protrudes from the outer surface of the first holding member 30 in the vicinity of the first hinge 22a. A rib 33 extending in the circumferential direction is provided on the inner surface of the first holding member 30 in the vicinity of the first hinge 22a. The ribs 33 prevent the pipe 100 from moving in the axial direction by applying resistance to the pipe 100 accommodated in the holding portion 11 in the axial direction (see FIG. 8).

On the inner surface of the first end 40a of the second holding member 40, a plurality of (the number of which is smaller than the number of the outward engaging claws 31. Three in this embodiment) inward engaging claws 41 are arranged in the circumferential direction. are provided at predetermined intervals along the A step 42 is provided on the outer surface of the second holding member 40 near the second hinge 23a. The second holding member 40 has a front-rear width on the side of the first end 40a bordering on the step 42 that is narrower than a width in the front-rear direction on the side of the second end 40b. A rib 43 extending in the circumferential direction is provided on the inner surface of the second holding member 40 in the vicinity of the second hinge 23a. The ribs 43 prevent the pipe 100 from moving in the axial direction by applying resistance to the pipe 100 held by the holding portion 11 in the axial direction (see FIG. 8).

A semicircular notch 34 is provided at the tip of the second end 30 b of the first holding member 30 . The inner diameter of the notch 34 is larger than the inner diameter of the attachment hole 21 a of the attachment portion 21 . A semicircular notch 44 is provided at the tip of the second end 40 b of the second holding member 40 . The inner diameter of the notch 44 is larger than the inner diameter of the attachment hole 21 a of the attachment portion 21 . The entrance 11c of the holding portion 11 is formed so that the entire cutouts 34 and 44 can be visually recognized when the elongated body holder 10 is viewed from above in the natural state of the first hinge 22a and the second hinge 23a (see FIG. 5). In addition, the width in the left-right direction is widened.

Therefore, when the elongated body holder 10 is viewed from above in the natural state of the first hinge 22a and the second hinge 23a (see FIG. 5), the mounting hole 21a of the mounting portion 21 is aligned with the first end 30a of the first holding member 30. and the second end 30b and the first and second ends 40a and 40b of the second holding member 40, and the mounting hole 21a is visible through the inlet 11c and the notches 34,44.

Therefore, when the long body holder 10 is screwed to the construction surface S, the mounting portion 21 can be attached from the inlet 11c of the holding portion 11 while the first hinge 22a and the second hinge 23a remain in their natural state. A screw (not shown) can be linearly moved to the hole 21a. Therefore, when the screws are inserted into the mounting holes 21a, for example, the first holding member 30 and the second holding member 40 are tilted by hand, that is, the first hinge 22a and the second hinge 23a are elastically deformed. No hassle.

At the first end 30 a of the first holding member 30 , first engagement marks 35 are provided on the front and rear of the outward engaging claw 31 closest to the entrance 11 c of the holding portion 11 . The first engagement mark 35 is provided so as to extend in the radial direction of the first holding member 30, and has a shape in which the width in the circumferential direction becomes narrower toward the inner side in the radial direction. At the proximal end of the first engagement mark 35, the end face on the side opposite to the entrance 11c is defined as a first reference 35a.

A second engagement mark 45 is provided on the outer surface of the first end 40 a of the second holding member 40 . The second engagement mark 45 is formed of a protrusion and has an isosceles triangle shape in a plan view. The second engagement mark 45 has an isosceles triangle-shaped base located near the inward engaging claw 41 that is farthest from the inlet 11c of the holding portion 11 among the plurality of inward engaging claws 41 . It is set up like this. The bottom side is defined as the second reference 45a.

Now, when the pipe 100 is held by the elongate body holder 10 in the state shown in FIGS. , the pipe 100 is inserted into the holding portion 11 via the inlet 11c (see FIG. 7 in particular). By pressing the pipe 100 inserted into the holding portion 11 against the second end 30b of the first holding member 30 and the second end 40b of the second holding member 40, the first holding member 30 engages the first hinge 22a. As a fulcrum, the second holding member 40 tilts with the second hinge 23a as a fulcrum. As the first holding member 30 and the second holding member 40 tilt, the inner diameter of the holding portion 11 becomes smaller.

Therefore, as shown in FIGS. 8 and 9, the first end 30a of the first holding member 30 and the first end 40a of the second holding member 40 approach each other, eventually closing the inlet 11c and further The outward engaging claws 31 of the first holding member 30 and the inward engaging claws 41 of the second holding member 40 are snap-engaged, and the pipe 100 is held between the first holding member 30 and the second holding member 40. sandwiched.

FIG. 8 is a diagram showing a state in which the long body holder 10 holds the pipe 100 (100A) having the smallest outer diameter among the corresponding pipe 100 sizes. In this state, the inward engaging claw 41 of the second holding member 40 is the outward engaging claw farther away from the inlet 11 c in the circumferential direction than the plurality of outward engaging claws 31 of the first holding member 30 . 31. Therefore, the snap engagement between the outward engaging pawl 31 and the inward engaging pawl 41 is advanced until the reaction force from the pipe 100 (100A) or the like increases to some extent, thereby reducing the inner diameter of the holding portion 11. It is possible to engage all of the plurality of inward engaging claws 41 with the outward engaging claws 31 by using only the outer engaging claws 31 .

The tip of the first end 30a of the first holding member 30 (the end surface of the first engagement mark 35) contacts the step 42, so that the inner diameter of the holding portion 11 is reduced to the minimum outer diameter of the pipe 100 (100A). It can be confirmed that it is suitable for holding

Here, FIG. 9 is a diagram showing a state in which the long body holder 10 holds the pipe 100 (100B) having the largest outer diameter among the sizes of the corresponding pipes 100. As shown in FIG. In this state, the inward engaging claws 41 of the second holding member 40 are engaged with the outward engaging claws 31 closer to the inlet 11c among the plurality of outward engaging claws 31 of the first holding member 30. are combined. Therefore, as shown in FIG. 11, for example, the snap engagement between the outward engaging pawl 31 and the inward engaging pawl 41 is performed until the reaction force from the pipe 100 (100B) or the like increases to some extent. In the judgment, it may not be possible to engage all of the plurality of inward engaging claws 41 with the outward engaging claws 31 .

In this case, as shown in FIGS. 11 and 12, the first engagement mark 35 of the first holding member 30 and the second holding member 40, which are separated in the left-right direction when the inlet 11c is open (see FIG. 1), are separated from each other. The second engagement mark 45 is that the second reference 45a of the second engagement mark 45 reaches between the first references 35a of the pair of first engagement marks 35 while approaching by closing the entrance 11c. not be a state. Therefore, the operator visually confirms that the second reference 45a of the second engagement mark 45 does not reach between the first references 35a of the pair of first engagement marks 35, thereby enabling the plurality of inward engagements. It can be seen that some of the claws 41 are not engaged with the outward engaging claws 31 .

The operator confirming that the inward engaging claw 41 is incompletely engaged with the outward engaging claw 31 further advances the snap engagement between the outward engaging claw 31 and the inward engaging claw 41 and holds the engagement. The inner diameter of the portion 11 is made small. Therefore, as shown in FIGS. 9 and 10, the second reference 45a of the second engagement mark 45 becomes the first reference of the pair of first engagement marks 35 as the inner diameter of the holding portion 11 becomes smaller. It almost reaches between 35a. By visually confirming that the second reference 45a of the second engagement mark 45 has almost reached between the first references 35a of the pair of first engagement marks 35, the operator confirms that all the inward engaging claws 41 are engaged. Engagement with the outward engaging claws 31 can be confirmed, and incomplete engagement of the plurality of inward engaging claws 41 with the outward engaging claws 31 can be easily avoided.

In this embodiment, the following effects can also be obtained.
(1) The first engagement mark 35 is provided on the first end 30a of the first holding member 30 on the inlet 11c side. The second engagement mark 45 is provided on the first end 40a of the second holding member 40 on the inlet 11c side. Therefore, while performing the work of inserting the pipe 100 into the holding portion 11, the change in the relative position between the first engagement mark 35 and the second engagement mark 45 can be visually recognized with a small movement of the line of sight, and workability is improved.

(2) A pair of the first engagement marks 35 are provided, and by tilting the first holding member 30 and the second holding member 40, the second engagement mark 45 ( This is a configuration through which the second holding member 40) passes. Therefore, it is easy to accurately grasp the relative positions of the first engagement mark 35 and the second engagement mark 45 . The operation of snap engagement with the dowel 41 can be performed accurately and easily.

(3) The second end 30b of the first holding member 30 and the second end 40b of the second holding member 40 are provided with cutouts 34, 44 that make the mounting hole 21a of the mounting portion 21 visible from the entrance 11c side, respectively. is provided. Therefore, by pressing the pipe 100 against the portions of the second ends 30b, 40b where the notches 34, 44 are not provided, the first holding member 30 and the second holding member 40 are tilted to close the inlet 11c. can be done. In other words, it is possible to achieve both the ease of screwing the mounting portion 21 and the function of a so-called one-touch pipe clamp at a high level.

(4) The finger hook 32 and the step 42 serve as a handhold for the operator when further advancing the snap engagement between the outward engaging claw 31 and the inward engaging claw 41, thereby facilitating the work.

(Another example)
For example, the present invention can also be implemented in the following aspects.
o When holding the pipe 100 on the elongated body holder 10 installed on the construction surface S of a high place, use a synthetic resin work tool 200 as shown in FIGS. 13 to 16. The work tool 200 is used in combination with an elongated stick 300 for the operator to handle. The bar 300 is a cylindrical body made of metal, synthetic resin, or wood.

The work tool 200 includes a cylindrical connecting portion 210 to which the tip of the rod 300 is press-fitted and fixed, and a holding portion 220 connected to the connecting portion 210 to hold the pipe 100 . A pair of holding portions 220 are provided spaced apart in the axial direction of the pipe 100 . Each holding portion 220 has a pair of holding pieces 221 . The holding piece 221 is for detachably holding the pipe 100 by elastic deformation. An engaging claw 221 a is provided on the outer surface of the tip of each holding piece 221 . The inner surface of each holding piece 221 is provided with a non-slip rib 221b for suppressing the movement of the pipe 100 in the axial direction.

As shown in FIG. 17, when the pipe 100 is held by the long body holder 10 installed on the work surface S at a high place, the pair of holding portions 220 of the work tool 200 are held respectively. The pipe 100 is pushed in from the tip side of the piece 221 to be sandwiched between the corresponding pair of holding pieces 221 . The work tool 200 holding the pipe 100 is lifted by manipulating the rod 300 and brought closer to the elongated body holder 10 .

Using the gap formed between the pair of holding portions 220, the portion of the pipe 100 positioned between the pair of holding portions 220 is removed while avoiding interference between the long body holder 10 and the work tool 200. By pressing against the elongated body holder 10, the outward engaging claws 31 of the first holding member 30 and the inward engaging claws 41 of the second holding member 40 are engaged (see FIGS. 7 and 8). . After the engagement is completed, the work tool 200 is pulled downward by manipulating the rod 300 , thereby elastically deforming the holding pieces 221 and separating the holding portions 220 of the work tool 200 from the pipe 100 . removed.

Conversely, when the pipe 100 is removed from the long body holder 10 installed on the construction surface S at a high place, the work tool 200 is lifted by manipulating the rod 300 and placed against the long body holder 10. Then, the engaging claw 221 a of one of the holding pieces 221 is hooked to the first end 40 a of the second holding member 40 in the elongated body holder 10 . By pulling the work tool 200 downward by manipulating the rod 300, the vicinity of the first end 40a of the second holding member 40 is elastically deformed, and the outward engaging claw 31 of the first holding member 30 is elastically deformed. and the inward engaging claws 41 of the second holding member 40 are released.

After the engagement is released, the pipe 100 may be dropped by its own weight, or the tip of each holding piece 221 of the work tool 200 may receive the pipe 100 about to drop, and the pipe 100 may be dropped into the work tool. 200 may be lowered slowly.

According to the work tool 200 (and rod 300) shown in FIGS. 13 to 17, the pipe 100 can be attached to and detached from the elongated body holder 10 installed on the construction surface S at a high place without using a stepladder or the like. It is possible, the efficiency of the work is improved, and the safety of the work is also advantageous.

Further, when the pipe 100 is attached to or detached from the long-body holder 10 , the pipe 100 is held on both sides of the long-body holder 10 by the pair of holding portions 220 . Therefore, it is possible to stably hold the pipe 100 against the long object holder 10 by pressing it.

A working tool 250 shown in FIG. 18 is different from the working tool 200 shown in FIGS. The pair of holding portions 220 can suitably hold both ends of the rectangular substrate 50 in the longitudinal direction through the cutouts 221c. A plurality of (two in the present embodiment) elongate body holders 10 are fixed to the substrate 50 by screwing, bonding with an adhesive, or sticking via double-sided tape. The substrate 50 to which the plurality of elongated body holders 10 are fixed is arranged such that the plurality of elongated body holders 10 are positioned between the pair of holders 220 , in other words, the plurality of elongated body holders 10 are positioned between the pair of holders 220 . is held by the holding portion 220 in a state in which it is turned upside down.

Then, after applying an adhesive or attaching a double-sided tape to the surface of the substrate 50 opposite to the elongated body holder 10, the substrate 50 and the work tool 250 are attached to each other by a rod. By the operation of 300, the substrate 50 is lifted to a high place, and the substrate 50 is pressed against the construction surface S and fixed. After the fixing of the substrate 50 to the construction surface S, in other words, the installation of the elongated body holder 10 is completed, the working tool 250 is pulled downward by operating the rod 300 to hold the working tool 250 . Part 220 is removed from substrate 50 . The pipe 100 is held by the long body holder 10 installed on the work surface S at a high place in this manner in the same manner as the working tool 200 shown in FIGS.

According to the work tool 250 shown in FIG. 18, the long body holder 10 and the pipe 100 can be installed on the work surface S at a high place without using a stepladder or the like, and the efficiency of the work is improved. It is also advantageous in terms of safety during the work. In this sense, the work tool 250 can also be understood as a work tool for holding the long body holder 10 . As another method of using the work tool 250, the pipe 100 is previously held by the elongated body holder 10, and the pipe 100 is moved to a high place together with the substrate 50 and the elongated body holder 10 at once. It is also possible to lift and install these sets on the construction surface S in one operation.

A work tool 260 shown in FIGS. 19 to 27 includes a cylindrical first connecting portion 270 press-fitted and fixed to the tip of a cylindrical rod 300, and a cylindrical first connection portion 270 press-fit and fixed to the tip of the rod 300. and a second connecting portion 271 . The first connecting portion 270 and the second connecting portion 271 are arranged in a positional relationship in which their central axes are perpendicular to each other. A common portion where the first connecting portion 270 and the second connecting portion 271 intersect is defined as an intersection portion 272 . The outer surfaces of the first connecting portion 270, the second connecting portion 271, and the intersecting portion 272 are hollowed to reduce the weight of the work tool 260. As shown in FIG.

A first holding portion 280 for holding the pipe 100 is provided on the opposite side of the intersection portion 272 to the first connecting portion 270 . The first holding portion 280 has a pair of holding pieces 281 . The holding piece 281 is for detachably holding the pipe 100 by elastic deformation. An engaging claw 281 a is provided on the outer surface of the tip of each holding piece 281 . Each engaging claw 281a has the same function as the engaging claw 221a of the work tools 200 and 250 shown in FIGS. 13 to 18 (disengages the outward engaging claw 31 from the inward engaging claw 41). It is what makes up. Each holding piece 281 is provided with guides 281b on both sides of the engaging claw 281a. The guide 281b is for preventing the engaging claw 281a from coming off the first end 40a of the long body holder 10 when the engaging claw 281a is hooked on the first end 40a of the long body holder 10 in order to fulfill this role. be. The inner surface of each holding piece 281 is provided with a non-slip rib 281c for suppressing the movement of the pipe 100 in the axial direction.

The outer surface of the crossing portion 272 on the opposite side of the second connecting portion 271 (the surface other than the hollowed portion) has a semi-cylindrical surface shape centered on the central axis of the first connecting portion 270. A semi-cylindrical portion serves as the second holding portion 285 . An insertion protrusion 285 a is provided on the second holding portion 285 on the center axis of the second connecting portion 271 .

As shown in FIG. 26 , when the pipe 100 is held by the elongated body holder 10 installed on the work surface S at a high place, the first connecting portion 270 of the work tool 260 is attached to the tip of the rod 300 . , and the pipe 100 is held by the first holding portion 280 in the same manner as the work tools 200 and 250 shown in FIGS.

As shown in FIG. 27, when installing the substrate 50 to which a plurality (two in this embodiment) of the elongated body holders 10 are fixed, on the work surface S at a high place, a working tool 260 is used. The second connecting portion 271 is press-fitted and fixed to the tip of the rod 300, and the second holding portion 285 is inserted into the holding portion 11 through the inlet 11c for one of the plurality of elongated body holders 10. do. Since the width of the second holding portion 285 (the outer diameter of the semi-cylindrical surface) is larger than the width of the inlet 11c, the second holding portion 285 is positioned between the first holding member 30 and the second holding member 40 at the inlet 11c. By tightening, the elongated body holder 10 is held with respect to the second holding portion 285 .
