Description

The present invention relates to a long object holder for holding long objects such as pipes used for supplying hot and cold water.

The elongated body holder disclosed in Patent Document 1 comprises a first holding member having a first holding recess, and a second holding member having a second holding recess that constitutes a holding portion surrounding the outer periphery of the elongated body together with the first holding recess. The first and second holding members are connected to each other, allowing the inlet of the water supply pipe in the holding portion to be opened and closed.

The first holding member has multiple outward engaging claws on the outer surface of the entrance end. The second holding member has multiple inward engaging claws on the inner surface of the entrance end that can engage with the outward engaging claws of the first holding member, the number of which is less than the number of outward engaging claws.

The elongated body holder can maintain the holding portion in a closed state by engaging the outward engaging claws with the inward engaging claws, and by changing the outward engaging claws that the inward engaging claws engage with, the inner diameter of the holding portion can be adjusted to hold water supply pipes of different outer diameters.

Japanese Patent Application Laid-Open No. 2018-179223

However, in the elongated body holder disclosed in Patent Document 1, the engagement portion between the outward engaging claws and the inward engaging claws was not highly exposed, making it difficult to visually confirm the engagement portion. Therefore, particularly when holding a water supply pipe with the largest outer diameter, some of the multiple inward engaging claws were not engaged with the outward engaging claws.

The object of the present invention is to provide a long object holder that can reliably engage all inward engaging claws with outward engaging claws.

In order to achieve the above object, the elongated body holder of the invention of claim 1 is used to attach an elongated body to a construction surface, and comprises a first holding member having a first holding recess, and a second holding member having a second holding recess that, together with the first holding recess, forms a holding portion that surrounds the outer periphery of the elongated body, the first holding member and the second holding member are connected to each other so that the entrance of the elongated body in the holding portion can be opened and closed, the outer surface of the entrance end of the first holding member is provided with a plurality of outward engaging claws, and the inner surface of the entrance end of the second holding member is provided with a plurality of inward engaging claws that can engage with the outward engaging claws of the first holding member, the number of which is less than the number of the outward engaging claws, and the outward engaging claws and the front The inward engaging claws engage with the elongated body holder, thereby keeping the entrance closed. Changing the outward engaging claws with which the inward engaging claws engage allows the inner diameter of the holding portion to be adjusted to hold elongated bodies of different outer diameters. The first holding member is provided with a first engaging mark, and the second holding member is provided with a second engaging mark. When the outward engaging claws with which the inward engaging claws engage are changed, the relative positions of the first engaging mark on the first holding member and the second engaging mark on the second holding member are changed, allowing the user to visually confirm that all of the inward engaging claws are engaged with the outward engaging claws by visually checking the relative positions of the first engaging mark and the second engaging mark.

The elongated body holder of claim 2 is the same as claim 1, except that the first engagement mark is provided at the entrance end of the first holding member, and the second engagement mark is provided at the entrance end of the second holding member.

The elongated body holder of the invention of claim 3 is the same as claim 1 or claim 2, in which a pair of first engagement marks are provided, and by changing the relative positions of the first engagement mark and the second engagement mark, the second engagement mark passes between the pair of first engagement marks.

The elongate body holder of the present invention allows the relative positions of the first and second engagement marks to be visually confirmed, ensuring that all inward engagement claws are engaged with the outward engagement claws.

Below, one embodiment of the present invention, embodied in a long-item holder for holding a long-item pipe for supplying hot and cold water, will be described with reference to Figures 1 to 12.

Note that Figure 1 is a front view of the elongated body holder 10, with the up-down direction in Figure 1 being the up-down direction of the elongated body holder 10, the left-right direction in Figure 1 being the left-right direction of the elongated body holder 10, and the front-to-back direction of the paper in Figure 1 being the front-to-back direction of the elongated body holder 10.

As shown in Figures 1 to 7, the elongated body holder 10 comprises a base 20 that is fixed to the construction surface S, and a pair of holding members (a first holding member 30 and a second holding member 40) that are attached to the base 20 and hold the pipe 100. The base 20, the first holding member 30, and the second holding member 40 are integrally molded from a synthetic resin such as polypropylene. In other words, the first holding member 30 and the second holding member 40 are connected to each other via the base 20.

The base 20 comprises a mounting portion 21 with a mounting hole 21a extending vertically in the center in the front-to-back and left-to-right directions, a first V-shaped columnar portion 22 erected on the right edge of the upper surface of the mounting portion 21, and a second V-shaped columnar portion 23 erected on the left edge of the upper surface of the mounting portion 21. The base 20 is secured to the construction surface S with screws via the mounting hole 21a in the mounting portion 21. The underside of the base 20 is provided with a sharp protrusion 20a that bites into the construction surface S, preventing the elongated body holder 10 from rotating when secured with the screws.

A first hinge 22a, which is a thin hinge, is provided at the tip of the first pillar-shaped portion 22. A second hinge 23a, which is also a thin hinge, is provided at the tip of the second pillar-shaped portion 23.

The first holding member 30 and the second holding member 40 are each semi-cylindrical. The first holding member 30 has a first holding recess 11a. The second holding member 40 has a second holding recess 11b, which together with the first holding recess 11a forms a holding portion 11 that surrounds the outer periphery of the pipe 100. An entrance 11c for inserting the pipe 100 into the holding portion 11 is provided 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, opposite the first end 30a.

The outer surface of the first holding member 30, located midway 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, located midway between the upper first end 40a and the lower second end 40b, is connected to the second columnar portion 23 via a second hinge 23a. The entrance 11c of the holding portion 11 is located on the axis of the mounting hole 21a of the mounting portion 21. The left-right width of the entrance 11c is greater than the inner diameter of the mounting hole 21a.

The first holding member 30 has multiple (nine in this embodiment) outward engaging claws 31 arranged at predetermined intervals along the circumferential direction on the outer surface of the first end 30a side. A finger hook 32 protrudes from the outer surface of the first holding member 30 near the first hinge 22a. A circumferentially extending rib 33 is provided on the inner surface of the first holding member 30 near the first hinge 22a. The rib 33 applies axial resistance to the pipe 100 housed in the holding portion 11, preventing the pipe 100 from moving in the axial direction (see Figure 8).

The second holding member 40 has multiple inward engaging claws 41 (fewer than the number of outward engaging claws 31; in this embodiment, three) spaced at predetermined intervals along the circumferential direction on the inner surface of the first end 40a. A step 42 is provided on the outer surface of the second holding member 40 near the second hinge 23a. The front-to-rear width of the second holding member 40 on the first end 40a side, bounded by the step 42, is narrower than the front-to-rear width of the second holding member 40 on the second end 40b side. A circumferentially extending rib 43 is provided on the inner surface of the second holding member 40 near the second hinge 23a. The rib 43 applies axial resistance to the pipe 100 held by the holding portion 11, preventing the pipe 100 from moving in the axial direction (see Figure 8).

A semicircular notch 34 is provided at the tip of the second end 30b of the first holding member 30. The inner diameter of the notch 34 is larger than the inner diameter of the mounting hole 21a of the mounting portion 21. A semicircular notch 44 is provided at the tip of the second end 40b of the second holding member 40. The inner diameter of the notch 44 is larger than the inner diameter of the mounting hole 21a of the mounting portion 21. The entrance 11c of the holding portion 11 is wide in the left-right direction so that the entire notches 34, 44 can be seen when the elongated body holder 10 is viewed from above with the first hinge 22a and second hinge 23a in their natural state (see Figure 5).

Therefore, when the elongate body holder 10 is viewed from above with the first hinge 22a and the second hinge 23a in their natural state (see Figure 5), the mounting hole 21a of the mounting portion 21 is not hidden by the first end 30a and second end 30b of the first holding member 30 or the first end 40a and second end 40b of the second holding member 40, and the mounting hole 21a is visible through the entrance 11c and the notches 34, 44.

Therefore, when fastening the elongate body holder 10 to the construction surface S with a screw, the first hinge 22a and the second hinge 23a remain in their natural state, and a screw (not shown) can be moved linearly from the entrance 11c of the holder portion 11 to the mounting hole 21a of the mounting portion 21. Therefore, when inserting the screw into the mounting hole 21a, there is no need to tilt the first holding member 30 or the second holding member 40 by hand, for example, i.e., to keep the first hinge 22a and the second hinge 23a in an elastically deformed state.

At the first end 30a of the first holding member 30, first engagement marks 35 are provided in front of and behind the outward engagement claw 31 that is closest to the entrance 11c of the holding portion 11. The first engagement marks 35 are provided so as to extend in the radial direction of the first holding member 30, and have a shape in which their circumferential width narrows as they move radially inward. At the base end of the first engagement mark 35, the end face opposite 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 40a of the second holding member 40. The second engagement mark 45 is a protrusion and has an isosceles triangle shape in a plan view. The second engagement mark 45 is provided so that the base of the isosceles triangle is located near the inward engagement claw 41 that is located farthest from the entrance 11c of the holding portion 11 among the multiple inward engagement claws 41. This base is the second reference 45a.

Now, when holding a pipe 100 in the elongated body holder 10 in the state shown in Figures 1 to 7 (assuming that the screws have been fastened to the construction surface S, and the first hinge 22a and second hinge 23a are in their natural state), the pipe 100 is inserted into the holding portion 11 through the entrance 11c (see Figure 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 tilts around the first hinge 22a as a fulcrum, and the second holding member 40 tilts around the second hinge 23a as a fulcrum. As the first holding member 30 and second holding member 40 tilt, the inner diameter of the holding portion 11 becomes smaller.

Therefore, as shown in Figures 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 entrance 11c, and then the outward engaging claws 31 of the first holding member 30 and the inward engaging claws 41 of the second holding member 40 snap together, clamping the pipe 100 between the first holding member 30 and the second holding member 40.

Figure 8 shows the state in which the elongated body holder 10 holds the pipe 100 (100A) with the smallest outer diameter of the corresponding pipe 100 size. In this state, the inward engaging claw 41 of the second holding member 40 is engaged with the outward engaging claw 31 of the multiple outward engaging claws 31 of the first holding member 30 that is the furthest circumferentially from the inlet 11c. Therefore, by simply progressing the aforementioned snap engagement between the outward engaging claw 31 and the inward engaging claw 41 until the reaction force from the pipe 100 (100A) etc. becomes sufficiently large and reducing the inner diameter of the holding portion 11, it is possible to engage all of the multiple inward engaging claws 41 with the outward engaging claws 31.

Furthermore, when the tip of the first end 30a of the first holding member 30 (the end face of the first engagement mark 35) abuts against the step 42, it can be confirmed that the inner diameter of the holding portion 11 is suitable for holding the pipe 100 (100A) with the smallest outer diameter.

Here, Figure 9 shows the state in which the elongated body holder 10 holds the pipe 100 (100B) with the largest outer diameter of the corresponding pipe 100 size. In this state, the inward engaging claw 41 of the second holding member 40 is engaged with the outward engaging claw 31 of the multiple outward engaging claws 31 of the first holding member 30 that is closest to the inlet 11c. Therefore, as shown in Figure 11, for example, it may not be possible to engage all of the multiple inward engaging claws 41 with the outward engaging claws 31 by judging only by the feel of the snap engagement between the outward engaging claw 31 and the inward engaging claw 41 until the reaction force from the pipe 100 (100B) or the like becomes sufficiently large.

In this case, as shown in Figures 11 and 12, the first engagement mark 35 of the first holding member 30 and the second engagement mark 45 of the second holding member 40, which were separated laterally when the entrance 11c was open (see Figure 1), approach each other as the entrance 11c is closed, but the second reference 45a of the second engagement mark 45 does not reach the gap between the first references 35a of the pair of first engagement marks 35. Therefore, by visually confirming that the second reference 45a of the second engagement mark 45 has not reached the gap between the first references 35a of the pair of first engagement marks 35, the worker can confirm that some of the multiple inward engagement claws 41 are not engaged with the outward engagement claws 31.

When the worker confirms that the inward engaging claws 41 are incompletely engaged with the outward engaging claws 31, he or she further advances the snap engagement between the outward engaging claws 31 and the inward engaging claws 41, thereby reducing the inner diameter of the holding portion 11. Therefore, as shown in Figures 9 and 10, the second reference 45a of the second engagement mark 45 will nearly reach the gap between the first references 35a of the pair of first engagement marks 35 as the inner diameter of the holding portion 11 decreases. By visually confirming that the second reference 45a of the second engagement mark 45 has nearly reached the gap between the first references 35a of the pair of first engagement marks 35, the worker can confirm that all of the inward engaging claws 41 are engaged with the outward engaging claws 31, easily avoiding incomplete engagement of multiple inward engaging claws 41 with the outward engaging claws 31.

This embodiment can also achieve the following effects: (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 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 confirmed with minimal eye movement, improving workability.

(2) A pair of first engagement marks 35 are provided, and tilting of the first holding member 30 and the second holding member 40 causes the second engagement mark 45 (second holding member 40) to pass between the pair of first engagement marks 35. Therefore, it is easy to accurately grasp the relative positions of the first engagement mark 35 and the second engagement mark 45, and the guiding action of the pair of first engagement marks 35 makes it possible to accurately and easily snap-engage the outward engagement claw 31 and the inward engagement claw 41.

(3) The second end 30b of the first holding member 30 and the second end 40b of the second holding member 40 each have a notch 34, 44 that allows the mounting hole 21a of the mounting portion 21 to be visible from the entrance 11c side. Therefore, by pressing the pipe 100 against the portion of the second end 30b, 40b where the notch 34, 44 is not provided, the first holding member 30 and the second holding member 40 can be tilted to close the entrance 11c. In other words, it is possible to achieve a high level of both ease of screwing the mounting portion 21 and the functionality of a so-called one-touch pipe clamp.

(4) The finger hook 32 and step 42 provide a guide for the operator when further advancing the snap engagement between the outward engaging claw 31 and the inward engaging claw 41, making the operation easier.

(Another Example) The present invention can also be implemented in the following manner, for example. When holding a pipe 100 to a long body holder 10 installed on a high-altitude construction surface S, a synthetic resin work tool 200, as shown in Figures 13 to 16, is used. The work tool 200 is used in combination with a long rod 300 that the worker holds. The rod 300 is a cylindrical body made of metal, synthetic resin, or wood.

The power tool 200 comprises a cylindrical connecting portion 210 into which the tip of the rod body 300 is press-fitted, 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 comprises a pair of holding pieces 221. The holding pieces 221 removably clamp and hold the pipe 100 by elastic deformation. An engaging claw 221a is provided on the outer surface of the tip of each holding piece 221. An anti-slip rib 221b is provided on the inner surface of each holding piece 221 to prevent the pipe 100 from moving in the axial direction.

As shown in Figure 17, when holding a pipe 100 in a long body holder 10 installed on a high construction surface S, the pipe 100 is pushed into a pair of holding portions 220 of the work tool 200 from the tip side of each holding piece 221, and the pipe 100 is clamped between the corresponding pair of holding pieces 221. The work tool 200, which is holding the pipe 100, is lifted by operating the rod body 300 and brought closer to the long body holder 10.

Then, using the gap formed between the pair of holding portions 220, the portion of the pipe 100 located between the pair of holding portions 220 is pressed against the elongated body holder 10 while avoiding interference between the elongated body holder 10 and the power tool 200, engaging the outward engaging claws 31 of the first holding member 30 with the inward engaging claws 41 of the second holding member 40 (see Figures 7 and 8). After this engagement is complete, the rod body 300 is operated to pull the power tool 200 downward, elastically deforming each holding piece 221 and releasing each holding portion 220 of the power tool 200 from the pipe 100.

Conversely, when removing a pipe 100 from an elongated body holder 10 installed on a high construction surface S, the work tool 200 is lifted by operating the rod body 300 and brought closer to the elongated body holder 10, and the engaging claw 221a of one of the holding pieces 221 is hooked onto the first end 40a of the second holding member 40 on the elongated body holder 10. Then, by operating the rod body 300 to pull the work tool 200 downward, the area near the first end 40a of the second holding member 40 elastically deforms, and the outward engaging claw 31 of the first holding member 30 and the inward engaging claw 41 of the second holding member 40 are disengaged.

After the engagement is released, the pipe 100 may be allowed to fall under its own weight, or the pipe 100 attempting to fall may be caught by the tips of the holding pieces 221 of the power tool 200, and the pipe 100 may be slowly lowered together with the power tool 200.

The work tool 200 (and rod 300) shown in Figures 13 to 17 allows the pipe 100 to be attached and detached to the elongated body holder 10 installed on the construction surface S at a high altitude without using a stepladder or the like, improving the efficiency of the work and also providing advantages in terms of safety during the work.

Furthermore, when attaching or detaching the pipe 100 to the elongated body holder 10, the pair of holding portions 220 hold the pipe 100 on both sides of the elongated body holder 10. Therefore, the pipe 100 can be pressed against the elongated body holder 10 and held in place stably.

The work tool 250 shown in Figure 18 is the work tool 200 shown in Figures 13 to 17, with a notch 221c provided on the inner surface of the tip of each holding piece 221. The pair of holding parts 220 can clamp and hold both longitudinal ends of the rectangular substrate 50 via the notches 221c. Multiple (two in this embodiment) elongated body holders 10 are fixed to the substrate 50 by screwing, bonding with an adhesive, or adhering with double-sided tape. The substrate 50 with multiple elongated body holders 10 fixed thereto is held by the holding parts 220 so that the multiple elongated body holders 10 are positioned between the pair of holding parts 220, in other words, with the multiple elongated body holders 10 upside down.

Then, after applying adhesive or applying double-sided tape to the surface of the substrate 50 opposite the elongated body holder 10, the substrate 50 and work tool 250 are lifted to a high position by operating the rod 300, and the substrate 50 is pressed against the construction surface S to secure it. After the substrate 50 has been secured to the construction surface S, in other words, after the installation of the elongated body holder 10 has been completed, the work tool 250 is pulled downward by operating the rod 300, and the holding portion 220 of the work tool 250 is detached from the substrate 50. The elongated body holder 10 thus installed on the construction surface S at an elevated location is used to hold the pipe 100 in the same manner as the work tool 200 shown in Figures 13 to 17.

18 , the work tool 250 allows the elongated body holder 10 and the pipe 100 to be installed on the construction surface S at a high altitude without using a stepladder or the like, improving the efficiency of the work and also providing advantages in terms of the safety of the work. In this sense, the work tool 250 can also be understood as a work tool for holding the elongated body holder 10. Note that another method of using the work tool 250 is to first hold the pipe 100 on the elongated body holder 10, then lift the pipe 100 together with the substrate 50 and the elongated body holder 10 to a high altitude at the same time, and install the entire set on the construction surface S in a single operation.

The power tool 260 shown in Figures 19 to 27 includes a cylindrical first connecting portion 270 that is press-fitted and fixed to the tip of a cylindrical rod body 300, and a cylindrical second connecting portion 271 that is press-fitted and fixed to the tip of the rod body 300. The first connecting portion 270 and the second connecting portion 271 are positioned such that their central axes are perpendicular to each other. The common portion where the first connecting portion 270 and the second connecting portion 271 intersect is called the intersection portion 272. Note that the outer surfaces of the first connecting portion 270, the second connecting portion 271, and the intersection portion 272 are each hollowed out to reduce the weight of the power tool 260.

On the opposite side of the intersection 272 from the first connecting portion 270, a first holding portion 280 for holding the pipe 100 is provided. The first holding portion 280 has a pair of holding pieces 281. The holding pieces 281 are designed to removably clamp and hold the pipe 100 by elastic deformation. An engaging claw 281a is provided on the outer surface of the tip of each holding piece 281. Each engaging claw 281a performs the same function as the engaging claw 221a of the power tools 200, 250 shown in Figures 13 to 18 (disengaging the outward engaging claw 31 and the inward engaging claw 41). Guides 281b are provided on both sides of the engaging claw 281a of each holding piece 281. The guides 281b prevent the engaging claw 281a from coming off the first end 40a of the elongated body holder 10 when the engaging claw 281a is hooked onto the first end 40a to fulfill its function. The inner surface of each holding piece 281 is provided with anti-slip ribs 281c to prevent the pipe 100 from moving in the axial direction.

The outer surface of the intersection 272 opposite the second connecting portion 271 (the surface other than the hollowed-out portion) forms a semi-cylindrical surface centered on the central axis of the first connecting portion 270, and this semi-cylindrical portion of the intersection 272 forms the second retaining portion 285. An insertion protrusion 285a is provided on the second retaining portion 285, on the central axis of the second connecting portion 271.

As shown in Figure 26, when holding a pipe 100 in an elongated body holder 10 installed on a high-altitude construction surface S, the first connecting portion 270 of the work tool 260 is press-fitted and fixed to the tip of the rod body 300, and the pipe 100 is held by the first holding portion 280 in the same manner as the work tools 200, 250 shown in Figures 13 to 18.

As shown in Figure 27, when installing a substrate 50 to which multiple (two in this embodiment) elongated body holders 10 are fixed on a high construction surface S, the second connecting portion 271 of the work tool 260 is press-fitted and fixed to the tip of the rod body 300, and the second holding portion 285 is inserted into the holding portion 11 of one of the multiple elongated body holders 10 through the entrance 11c. Because the width (outer diameter of the semi-cylindrical surface) of the second holding portion 285 is larger than the width of the entrance 11c, the second holding portion 285 is tightened between the first holding member 30 and the second holding member 40 at the entrance 11c, and the elongated body holder 10 is held by the second holding portion 285.

Here, in the work tool 260, the surfaces that abut against the first holding member 30 and second holding member 40 of the elongated body holder 10 are semi-cylindrical similar to the outer surface of the pipe 100, which allows for smooth insertion of the second holding portion 285 into the elongated body holder 10 (holding portion 11). Furthermore, because the outer surface of the second holding portion 285 is hollowed out, the second holding portion 285 better catches on the first holding member 30 and second holding member 40 of the elongated body holder 10, ensuring reliable retention of the elongated body holder 10 by the second holding portion 285.

When the elongated body holder 10 is held by the second holding portion 285, the insertion protrusion 285a of the second holding portion 285 is inserted between the notches 34 and 44 of the elongated body holder 10. Therefore, the insertion protrusion 285a of the work tool 260 abuts against the inner edges of the notches 34 and 44 of the elongated body holder 10, preventing the elongated body holder 10, or in other words the substrate 50, from tilting relative to the work tool 260 or shifting in the direction of the central axis of the first connecting portion 270, thereby ensuring reliable installation (adhesion) of the substrate 50 to the construction surface S.

The work tool 260 shown in Figures 19 to 27 has separate connecting portions (first connecting portion 270 and second connecting portion 271) to which the rod body 300 is fixed when holding the pipe 100 against the elongated body holder 10 installed on the construction surface S at a high altitude, and when installing the base plate 50 to which the elongated body holder 10 is fixed on the construction surface S. This allows for more space to be allocated to the first holding portion 280 for holding the pipe 100 and the second holding portion 285 for holding the elongated body holder 10, increasing the degree of freedom in the design of each of the first holding portion 280 and the second holding portion 285.

- Integrating the connecting portion 210 and the rod body 300 of the power tools 200, 250, for example by integrally molding the connecting portion 210 with the rod body 300.

○ The first engagement mark 35 should be located near the outward engagement claw 31 that is located farthest from the entrance 11c among the multiple outward engagement claws 31.

- The second engagement mark 45 should be located near the inward engagement claw 41 that is closest to the entrance 11c among the multiple inward engagement claws 41.

The number of outward engaging claws 31 should be less than or more than three times the number of inward engaging claws 41. In particular, if the number of outward engaging claws 31 is more than twice the number of inward engaging claws 41, the number of outward engaging claws 31 that are not in use and are exposed when holding the pipe 100 (100B) with the largest outer diameter will be large, in other words, the number of outward engaging claws 31 that are not engaged with the inward engaging claws 41 will be large, making it difficult to accurately determine this number. Therefore, without using the first engagement mark 35 and the second engagement mark 45, it will be difficult to confirm that all inward engaging claws 41 are engaged with their corresponding outward engaging claws 31. In other words, the present invention is particularly effective when the number of outward engaging claws 31 is more than twice the number of inward engaging claws 41.

○ The outward engagement claw 31 and/or second engagement mark 45 can be provided by recessing or painting.

○ Changing the first hinge 22a and/or the second hinge 23a to a hinge using an axis member.

The elongated body holder 10 in the above embodiment was a so-called one-touch pipe clamp that used the force of inserting the pipe 100 into the holding portion 11 to tilt the first holding member 30 and the second holding member 40 to close the entrance 11c. This can be modified to create a elongated body holder 10 that, after inserting the pipe 100 into the holding portion 11, allows the operator to directly tilt the first holding member 30 and the second holding member 40 with their fingers to close the entrance 11c.

○Other application surfaces include vehicle body surfaces.

○Other pipes include drainage pipes and gas pipes. Long objects other than pipes include wire harnesses and optical fibers.
