Description

[Technical Field]

[0001] The present invention relates to a fixture for fastening a long object, such as a pipe, a cable, or another long object, to a structure. [Background technology]

[0002] The elongated body is often fixed to the wall, ceiling, floor, or other structural components of a building. By fixing the elongated body to the structural components, users of the building can effectively use the space that the building comprises.

[0003] The elongated body is fixed to the structure by a fixture for fixing the elongated body. The fixture for fixing the elongated body comprises a support that is fixed to the structure and a holder that is attached to the support and sandwiches the elongated body. As the support, for example, a platform-shaped member having a rear surface that is fixed to the structure and a front surface on which the elongated body is supported is often used. The rear surface of such a support is fixed to the structure with adhesive, screws, or other fastening parts. A holder is attached to the front surface of the support and sandwiches the elongated body.

[0004] For example, Japanese Patent Application Laid-Open Publication No. 2019-044852 (Patent Document 1) discloses a long body fixing tool (mounting jig) for fixing a long body (1) to a structure. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2019-044852 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the support (base A) of the fixture (mounting jig) for a long body described in Patent Document 1 has a fixed size (diameter) of the long body (1) that can be fixed and a fixed position of the long body (1). For this reason, it is desirable to realize a fixture for a long body that allows a large degree of freedom in fixing a long body to a structure. [Means for solving the problem]

[0007] The elongated body fixing device of the present invention is a elongated body fixing device that fixes a elongated body to a structure, and comprises a support that is fixed to the structure, and a retainer that is attached to the support and sandwiches the elongated body, the support having bases that are arranged at intervals in the longitudinal direction and have engageable portions that can engage with engageable portions of the retainer, and the number of engageable portions is greater than the number of engageable portions.

[0008] According to this configuration, the holder can attach the elongated body to any of a plurality of positions in the longitudinal direction of the base, thereby increasing the degree of freedom in attaching the elongated body to the structure.

[0009] Preferred embodiments of the present invention will be described below, but the scope of the present invention is not limited to the preferred embodiments described below.

[0010] In one embodiment, the support has a pair of the engaging portions, and the holder has three or more of the engaged portions.

[0011] According to this configuration, multiple types of holders with different intervals between the pair of engagement parts can be attached to the base. Since the elongated object held by the holder having a pair of engagement parts is positioned between the pair of engagement parts and attached to the base, by attaching fixing devices with different intervals between the pair of engagement parts to the base, elongated objects of various sizes can be fixed to the base.

[0012] In one embodiment, the holder can be selected from multiple types having different lengths between the pair of engaging portions, and the length between adjacent engaged portions corresponds to a common divisor of the lengths between the pair of engaging portions in the multiple types of holder.

[0013] According to this configuration, a plurality of types of holders having different lengths between the pair of engaging portions can be appropriately attached to the base.

[0014] The base further has a connecting portion that can be connected to another base in the longitudinal direction.

[0015] According to this configuration, by connecting one support to another support, it is possible to increase the number of engaged parts arranged in the longitudinal direction and expand the area in which the engaged parts are arranged, thereby increasing the degree of freedom in the position, size, and number of elongated bodies fixed to the structure.

[0016] The holder can be selected from multiple types having different lengths between the pair of engaging portions, and when one base is connected to another base, the length between the pair of engaged portions located on either side of the connecting portion is the smallest length among the lengths between the pair of engaging portions in the multiple types of holder.

[0017] This configuration allows multiple types of holders with different lengths between the pair of engaging portions to be appropriately attached to one support and another support, thereby increasing the degree of freedom in the position, size, and number of elongated objects to be attached to the structure.

[0018] In one embodiment, the support further includes a fixed base disposed between the structure and the base, and the fixed base and the base are configured to be detachable from each other.

[0019] With this configuration, it is easy to make various adjustments to suit the requirements for attaching the elongated body to the structure, such as the fixing position of the elongated body in the vertical direction away from or approaching the structure, the attachment manner of the support to the structure, and other requirements for attaching the elongated body to the structure.

[0020] In one embodiment, the support further includes a fixed base arranged between the structure and the base, the fixed base having a pair of fixed portions each fixed to either the structure or the base, and an intermediate portion connecting the pair of fixed portions to each other, and the thickness of the intermediate portion in the short direction is thinner than the thickness of the base in the short direction.

[0021] According to this configuration, for example, when insulation is performed between a structure and a base, the area where insulation material cannot be installed can be reduced by using an intermediate portion that is thinner than the thickness of the base in the short direction, thereby reducing the area that is considered to be an insulation defect.

[0022] In one embodiment, the support further includes a fixed base arranged between the structure and the base, and the fixed base has an extendable structure that extends and contracts in the vertical direction to move away from or approach the structure.

[0023] According to this configuration, the fixing position of the elongated body in the height direction can be adjusted using the telescopic structure, which eliminates the need to prepare multiple fixing bases with different height dimensions for adjusting the fixing position of the elongated body, thereby reducing the number of parts required to fix the elongated body to a structure.

[0024] In one aspect, in a configuration in which the support includes the fixed base having the expansion and contraction structure, the expansion and contraction structure expands and contracts by a predetermined expansion and contraction amount.

[0025] According to this configuration, since the amount of expansion and contraction of the expansion structure is determined in advance, it is easy to simplify the structure for maintaining the expanded and contracted state of the expansion structure. [Brief explanation of the drawings]

[0027] 1. Overview of the elongated body fixing device of the first embodiment As shown in FIG. 1, the elongated body fixing device 1 is a fixing device for fixing the elongated body 10 to a structural body W. The elongated body 10 can be placed at an edge or corner of a building by being fixed to the structural body W by the elongated body fixing device 1. This allows users of the building to effectively use the space that the building constitutes. FIG. 1 shows the ceiling surface of a building as an example of the structural body W, and piping as an example of the elongated body 10.

[0028] The elongated body fixing device 1 includes a support 2 fixed to the structure W, and a holder 3 attached to the support 2 with the elongated body 10 sandwiched between them. The support 2 is fixed to the structure W, for example, by adhering to the structure W with an adhesive or fastening to the structure W with fastening parts such as screws.

[0029] In order to attach the holder 3 to the support 2, the support 2 and the holder 3 have an engagement structure that engages with each other. As the engagement structure, the holder 3 has an engagement portion 31. The engagement portion 31 engages with an engaged portion 22 formed on the support 2. In this embodiment, the holder 3 has a pair of engagement portions 31. The pair of engagement portions 31 have a holding function that holds the elongated body 10 from a direction intersecting the attachment / detachment direction, in addition to a detachable function that engages with the engaged portion 22. In detail, the pair of engagement portions 31 sandwich the elongated body 10 from a direction intersecting the attachment / detachment direction. An example of a holder 3 that has both an attachment / detachment function and a holding function is a saddle as illustrated in FIG. 1.

[0030] The holder 3 can be selected from a variety of types with different lengths between the pair of engagement portions 31. Specifically, different sizes of holders 3 are selected depending on the size (e.g., outer diameter) of the elongated body 10. The size of the elongated body 10 that can be held by the holder 3 is determined by the distance between the support 2 and the holder 3 in the space where the support 2 and the holder 3 sandwich the elongated body 10 when the holder 3 is attached to the support 2, and the distance between the pair of engaging portions 31. The upper limit of the size of the elongated body 10 that can be held by the holder 3 illustrated in FIG. 1 is determined by the distance between the pair of engaging portions 31. This is because the distance between the pair of engaging portions 31 is larger than the distance between the support 2 and the holder 3 in the space where the support 2 and the holder 3 sandwich the elongated body 10. With this configuration, the worker can determine the holder 3 that corresponds to the size of the elongated body 10 to be fixed to the structure W simply by checking the distance between the pair of engaging portions 31.

[0031] 2. Structure of the support device of the embodiment 1 to 3 and 8, the support 2 includes at least a base 21. The base 21 is a member to which the holder 3 is attached.

[0032] 2-1. Bass In this embodiment, the base 21 extends along the structure W in one direction (longitudinal direction X). The base 21 illustrated in FIGS. 1 to 3 is a box-shaped member. In detail, the base 21 includes a pair of side surfaces 211 extending along a longitudinal direction X, a pair of connecting surfaces 212 arranged along a lateral direction Y intersecting the longitudinal direction X, a fixing surface 213, and an attachment surface 214. The fixing surface 213 is a surface that is fixed directly or indirectly to the structure W. The fixing surface 213 illustrated in FIGS. 1 to 3 is arranged in a position facing the structure W. The attachment surface 214 is a surface to which the holder 3 is attached. The attachment surface 214 illustrated in FIG. 1 is arranged on the opposite side of the structure W with respect to the fixing surface 213. Note that, hereinafter, for ease of explanation, the term "longitudinal direction X" refers to the longitudinal direction X of the base 21, and the term "lateral direction Y" refers to the lateral direction Y of the base 21.

[0033] The base 21 has engaged portions 22 that can engage with a pair of engaging portions 31 of the holder 3. The engaged portions 22 are arranged at intervals in the longitudinal direction X. The number of engaged portions 22 is greater than the number of engaging portions 31. In this embodiment, the base 21 has three or more engaged portions 22. The engaged portions 22 are formed on a surface that constitutes the base 21. The engaged portions 22 illustrated in FIGS. 1 and 3 are formed on the mounting surface 214.

[0034] In this embodiment, as shown in Fig. 3, the engaged portion 22 includes an engaged piece 221 with which the engaging portion 31 of the holder 3 engages, and an engaged hole 222 adjacent to the engaged piece 221. The engaged piece 221 illustrated in Fig. 3 is a rod-shaped portion extending in the short direction Y. The engaged hole 222 is a through hole that contacts the engaged piece 221 on one side in the longitudinal direction X. In the example of Fig. 3, the multiple through holes formed in the mounting surface 214 are the engaged holes 222, and the member that forms the edge portion on one side in the longitudinal direction X of the engaged hole 222 is the engaged piece 221.

[0035] Preferably, as illustrated in FIG. 4 , the length between adjacent engaged portions 22 (the engaged dimension L22) corresponds to a common divisor of the lengths between pairs of engaging portions 31 (the engaging dimension L31) of multiple types of holders 3. This configuration allows the operator to attach multiple types of holders 3 to the base 21. Additionally, the phrase "one dimension corresponds to another dimension" not only means that one dimension exactly matches the other dimension, but also means that they are roughly the same with some slight differences. A slight difference could be, for example, a dimensional difference due to manufacturing error or a dimension that is acceptable for achieving the purpose. In other words, the phrase "the engaged dimension L22 corresponds to the engaging dimension L31" refers to the concept of both dimensions being different enough to allow multiple types of holders 3 to be attached to the base 21.

[0036] In this embodiment, the inter-engagement dimension L22 is the length from the center of one engaged hole 222 to the center of the adjacent engaged hole 222 across the engaged piece 221. The inter-engagement dimension L31 is the length from the center of one engaging portion 31 to the center of the other engaging portion 31 in a pair of engaging portions 31. FIG. 4 illustrates a first holder 34 capable of holding the first elongated body 11 and a second holder 35 capable of holding a second elongated body 12 that is smaller than the first elongated body 11. Here, if the inter-engagement dimension L31 of the first holder 34 is the first inter-engagement dimension L34 and the inter-engagement dimension L31 of the second holder 35 is the second inter-engagement dimension L35, in this embodiment, the common divisor of the first inter-engagement dimension L34 and the second inter-engagement dimension L35 corresponds to the inter-engagement dimension L22. Therefore, the pair of engaging portions 31 of the first holder 34 and the pair of engaging portions 31 of the second holder 35 engage with any of the multiple engaged portions 22 formed on the base 21. Therefore, both the first holder 34 and the second holder 35 can be attached to the support 2.

[0037] Preferably, the inter-engagement dimension L22 corresponds to the greatest common divisor of the lengths between the pair of engaging portions 31 of the multiple types of holders 3. With this configuration, the inter-engagement dimension L22 is the longest among the inter-engagement dimensions L22 that can accommodate all of the multiple types of holders 3 to be attached to the support 2, making it easier to increase the rigidity of the base 21.

[0038] Preferably, the base 21 further has a connecting portion 24 connectable to another base 21 in the longitudinal direction X, as shown in Fig. 5. In this embodiment, the connecting portion 24 is formed at an end portion of the base 21 in the longitudinal direction X. In the example shown in Fig. 5, one base 21 and another base 21 are arranged along the longitudinal direction X. The connecting portion 24 formed on a connecting surface 212 on one side in the longitudinal direction X of the one base 21 is connected to the connecting portion 24 formed on a connecting surface 212 on the other side in the longitudinal direction X of the other base 21.

[0039] More preferably, the base 21 has a pair of connecting portions 24 on both sides in the longitudinal direction X. With this configuration, different bases 21 can be connected to each other in sequence, and three or more bases 21 can be connected as a whole. Therefore, the base 21 having a pair of connecting portions 24 can increase the degree of freedom in the position at which the elongated body 10 is arranged.

[0040] In this embodiment, a first connecting portion 241, which is one of the pair of connecting portions 24, is configured to fit into a second connecting portion 242, which is the other of the pair of connecting portions 24. In this embodiment, the first connecting portion 241 corresponds to the hole-side structure in the fitting structure, and the second connecting portion 242 corresponds to the shaft-side structure in the fitting structure. The first connecting portion 241 is formed at an end portion in the longitudinal direction X of the base 21 disposed on one side in the longitudinal direction X, and the second connecting portion 242 is formed at an end portion in the longitudinal direction X of the base 21 disposed on the other side in the longitudinal direction X. In FIG. 5 , in the base 21, the connecting portion 24 drawn on the right side as you face the page is the first connecting portion 241, and the connecting portion 24 drawn on the left side as you face the page is the second connecting portion 242.

[0041] In the example shown in FIG. 5, the first coupling portion 241 is a portion recessed from the connection surface 212 in the longitudinal direction X, and the second coupling portion 242 is a portion protruding from the connection surface 212 in the longitudinal direction X. The first coupling portion 241 illustrated in FIG. 5 is recessed in the longitudinal direction X at the connection surface 212, leaving only an edge portion connecting to the side surface 211 and an edge portion connecting to the mounting surface 214. The second coupling portion 242 illustrated in FIG. 5 has a structure in which only a portion that abuts against the first coupling portion 241 protrudes. In detail, the second coupling portion 242 is structured to occupy a portion excluding a center position on the connection surface 212, an edge portion on the connection surface 212 that abuts against the structure W, and a portion that interferes with the first coupling portion 241 when the first coupling portion 241 and the second coupling portion 242 are connected.

[0042] In the present embodiment, the first connecting portion 241 and the second connecting portion 242 further have a restricting structure that restricts relative movement between them in the longitudinal direction X. With this configuration, the first connecting portion 241 and the second connecting portion 242 are firmly connected to each other. The first connecting portion 241 illustrated in FIG. 5 has, as the restricting structure, a groove 24P recessed in a direction intersecting the longitudinal direction X. A pair of grooves 24P are provided opposite each other in the lateral direction Y, and each groove 24P is recessed in the lateral direction Y. The second connecting portion 242 illustrated in FIG. 5 has, as the restricting structure, a protrusion 24D that fits into the groove 24P of the first connecting portion 241.

[0043] In this embodiment, when one base 21 is connected to another base 21, the length between a pair of engaged portions 22 located on either side of the connecting portion 24 is the smallest length among the lengths between a pair of engaging portions 31 in multiple types of holders 3.

[0044] 2-2.Fixed stand Preferably, the support 2 further includes a fixed base 23, as shown in FIGS. 1 and 2. The fixed base 23 is disposed between the structure W and the base 21. The fixed base 23 and the base 21 are configured to be detachable. In this embodiment, the base 21 is indirectly fixed to the structure W via the fixed base 23. This allows the base 21 to be disposed at a position spaced apart from the structure W. With this structure, the support 2 can be fixed to the structure W even when it is necessary to dispose the elongated body 10 at a certain distance from the structure W, as exemplified in FIGS. 1 and 2. An example of such a case is when a heat insulating material is applied to the structure W.

[0045] In this embodiment, the fixed base 23 has a platform portion 231 and a detachable portion 232. The detachable portion 232 is formed in a portion of the platform portion 231 that comes into contact with the base 21.

[0046] The platform portion 231 is a structural member that supports the base 21 on the structure W. The platform portion 231 includes a pair of fixed portions 23P, each fixed to either the structure W or the base 21, and an intermediate portion 23C that connects the pair of fixed portions 23P to each other. The pair of fixed portions 23P are arranged at an interval in the height direction Z, in which the base 21 moves away from or toward the structure W. The intermediate portion 23C determines the height position of the base 21 from the structure W. The thickness of the intermediate portion 23C in the short side direction Y is thinner than the thickness of the base 21 in the short side direction Y.

[0047] According to this configuration, the area where the insulation material cannot be installed can be reduced by the intermediate portion 23C, which is thinner than the thickness of the base 21 in the short direction Y, and therefore the area considered to be an insulation defect can be reduced. In addition, as shown in FIG. 2, by using a fixing base 23 having an intermediate portion 23C of an appropriate length for each construction site, the distance (floating height) from the structure W to the base 21 can be easily adjusted. Therefore, when installing insulation material on the structure W, it is easy to accommodate differences in the thickness of the insulation layer at each construction site.

[0048] Preferably, the thickness of the intermediate portion 23C in the short-side direction Y is thinner than the thickness of the fixed portion 23P in the short-side direction Y. According to this configuration, it is possible to increase the area of ​​the surface of each of the pair of fixed portions 23P that is fixed to the structure W or the base 21. Therefore, it is possible to strengthen the fixation between each of the pair of fixed portions 23P and the structure W or the base 21, while reducing the area of ​​thermal insulation defects in the thermal insulating material.

[0049] In this embodiment, one of the pair of fixed portions 23P is fixed to the structure W with an adhesive or the like. The other of the pair of fixed portions 23P is fixed to the base 21 via a detachable portion 232. The pair of fixed portions 23P illustrated in FIGS. 1 and 2 are each plate-shaped and extending in the longitudinal direction X. The middle portion 23C is plate-shaped and extending in the height direction Z.

[0050] Hereinafter, for ease of explanation, the side of the height direction upper side Z1 approaching the structure W will be referred to as the "height direction upper side Z1," and the side of the height direction upper side Z1 moving away from the structure W will be referred to as the "height direction lower side Z2." Additionally, in this embodiment, the attachment / detachment direction in which the support 2 and the holder 3 are attached and detached coincides with the height direction Z. However, the attachment / detachment direction and the height direction Z do not necessarily have to coincide.

[0051] 1 is made up of four claws that protrude from fixed portion 23P toward base 21. Two of the four claws are engaged with one of a pair of side surfaces 211 of base 21, and the remaining two of the four claws are engaged with the other of the pair of side surfaces 211 of base 21. In this way, by providing detachable portion 232 on a surface of base 21 other than the surface on which engaged portion 22 is formed and the surface on which connecting portion 24 is formed, the entire structure of support 2 can be simplified and support 2 can be made smaller.

[0052] 3. Structure of the holder of the embodiment As shown in FIGS. 1 to 3 and 9, the holder 3 has an engaging portion 31 and a restricting portion.

[0053] 3-1.Engagement part As shown in Figure 3, the engaging portion 31 has an engaging piece 311 that engages with the engaged portion 22 to restrict movement of the holder 3 toward the side where it is removed from the support 2, and a deformation structure that positions the engaging piece 311 at an engaging position where the engaging piece 311 engages with the engaged portion 22.

[0054] The deformation structure is deformed by an externally applied force from the engagement position to a disengagement position where the engagement piece 311 does not engage with the engaged portion 22. In this embodiment, the deformation structure is deformed by a force applied to either the engagement piece 311 or the deformation structure to dispose the engagement piece 311 from the engagement position to the disengagement position. Hereinafter, the engagement position and the disengagement position will be explained together with the structure of the engagement piece 311. In addition, the state of the deformation structure when the engagement piece 311 is respectively disposed in the engagement position and the disengagement position will be explained. Hereinafter, for convenience of explanation, the deformation of the deformation structure may be referred to as the deformation of the holder 3.

[0055] 3-1-1. Engagement position When the holder 3 is attached to the support 2, the engaging piece 311, which is positioned at the engaging position, restricts movement of the engaging portion 31 toward the side where the holder 3 is removed from the support 2. In this embodiment, as shown in the lower part of FIG. 6 , the engaging position is a position where the engaging piece 311 provided on the engaging portion 31 is on the upper side Z1 in the height direction relative to the engaged piece 221. The engaging piece 311 is formed to protrude in the longitudinal direction X. Therefore, when the engaging piece 311 positioned at the engaging position is moved downward Z2 in the height direction, the engaging piece 311 comes into contact with the engaged piece 221. As a result, movement of the engaging piece 311 toward the lower side Z2 in the height direction is restricted by the engaged piece 221.

[0056] When the holder 3 is removed from the support 2, it deforms so that the engaging piece 311 can pass through the engaged hole 222 as it moves from the initial position to the engaged position. In this embodiment, as shown in FIG. 3 , the initial position is a position where the engaging piece 311 is on the lower side Z2 in the height direction relative to the engaged piece 221. As the holder 3 moves from the initial position to the engaged position, the engaging piece 311 is pressed against the engaged portion 22. As a result, the force applied to the engaging piece 311 causes the holder 3 to deform into a shape that allows the engaging piece 311 to pass through the engaged hole 222.

[0057] 3 is inclined in the longitudinal direction X so that the surface that presses against the engaged portion 22 approaches the engaged piece 221 from the upper side Z1 in the height direction to the lower side Z2 in the height direction when viewed from the short direction Y. When the engaging piece 311 passes through the engaged hole 222, the force applied to the engaging piece 311 by being pressed against the engaged piece 221 is released. This causes the shape of the holder 3 to be partially or completely restored, and the engaging piece 311 is placed in the engaging position. As a result, the engaging piece 311 comes into contact with the engaged piece 221 from the upper side Z1 in the height direction, and the holder 3 is prevented from coming off the support 2.

[0058] 3-1-2. Disengaged position The non-engagement position is a position of the engaging piece 311 where the engaging piece 311 does not engage with the engaged portion 22 when the engaging piece 311 is moved in the attachment / detachment direction. In this embodiment, the non-engagement position is a position of the engaging piece 311 where the engaging piece 311 can pass through the engaged hole 222 when the engaging piece 311 is moved in the height direction Z. When an external force is applied to the holder 3, the holder 3 is deformed so that the engaging piece 311 is positioned at the non-engagement position in any of the states where the engaging piece 311 is positioned at the initial position, where the engaging piece 311 moves from the initial position to the engaged position, and where the engaging piece 311 is positioned at the engaged position.

[0059] The holder 3 can be deformed by the force of the fingers into a position that releases the engagement between the engaged portion 22 and the engaging piece 311. In detail, when a force is applied by the fingers to the holder 3 with the engaging piece 311 arranged in the engagement position in a direction that moves the engaging piece 311 away from the engaged piece 221, the holder 3 deforms into a shape in which the engaging piece 311 moves away from the engaged piece 221, as shown in the lower part of Fig. 7. In this state, the holder 3 can be removed from the support 2 by moving the holder 3 toward the removal side (in this embodiment, the lower side Z2 in the height direction) in the attachment / detachment direction.

[0060] 3-1-3. Deformation structure In this embodiment, as shown in FIGS. 1 to 3 , the deformation structure has engagement legs 312, retention legs 313, flexible portions 314, and side walls 315. The engagement legs 312 are portions on which the engagement pieces 311 are formed. The retention legs 313 are portions that hold the engagement legs 312. The flexible portions 314 connect the engagement legs 312 and the retention legs 313. The side walls 315 hold the retention legs 313 and the engagement legs 312 connected to the retention legs 313. The engagement legs 312, retention legs 313, flexible portions 314, and side walls 315 that constitute the deformation structure are formed as a whole in a box shape that opens to the lower side Z2 in the height direction.

[0061] In this embodiment, the engagement leg 312 is a member that extends in the attachment / detachment direction. The engagement leg 312 illustrated in Fig. 3 is a member that extends in the height direction Z. In this embodiment, the engagement leg 312 is formed in a thin plate shape that is thinner than the holding leg 313. The engagement piece 311 protrudes in the longitudinal direction X from a portion of the engagement leg 312 on the upper side Z1 in the height direction.

[0062] In this embodiment, the holding leg 313 is disposed at an interval in the longitudinal direction X from the engaging leg 312 and is a member extending in the attachment / detachment direction. The holding leg 313 illustrated in Fig. 3 is disposed on the opposite side of the engaging leg 312 from the side from which the engaging piece 311 protrudes, and extends in the height direction Z. The holding leg 313 illustrated in Fig. 3 is connected to the engaging leg 312 at an end on the upper side Z1 in the height direction by a flexible portion 314 that is folded back in a hairpin shape.

[0063] In this embodiment, the flexible portion 314 connects the engagement leg 312 to the holding leg 313 so as to bend in a direction approaching the holding leg 313. In this embodiment, as shown in Fig. 3, the flexible portion 314 connects an end of the engagement leg 312 on the upper side Z1 in the height direction to an end of the holding leg 313 on the upper side Z1 in the height direction.

[0064] In this embodiment, the side wall 315 is disposed on either side of the retaining leg 313 and the engaging leg 312 in the short-side direction Y, and is connected to the retaining leg 313. The engaging leg 312 and the side wall 315 are separated by a slit 316 as shown in FIG. 1 . According to this configuration, when a force is applied to the engaging leg 312 with a finger in the longitudinal direction X toward the retaining leg 313, the flexible portion 314 is flexibly deformed so that the tip of the engaging leg 312 (the end on the lower side Z2 in the height direction) approaches the tip of the retaining leg 313 (the end on the lower side Z2 in the height direction). In this way, the deformable structure of this embodiment is formed into a box shape as a whole, but only the engaging leg 312, which forms one of the walls, is primarily deformed. In this embodiment, a pair of side walls 315 are provided, and are disposed separately on both sides in the short-side direction Y.

[0065] Preferably, the engagement leg 312 further has a holding piece 31P that can be grasped with the fingers. The holding piece 31P is provided on the removal side in the attachment / detachment direction (in this embodiment, on the lower side Z2 in the height direction) with respect to the flexible portion 314 and the engagement piece 311. According to this configuration, when the engagement piece 311 is placed in the engagement position, the holding piece 31P is exposed to the outside of the support tool 2. This makes it easier to grasp the holding piece 31P with the fingers, and the operator can easily deform the engagement leg 312 in the longitudinal direction X toward the holding leg 313.

[0066] In this embodiment, as described above, the holder 3 has a pair of engaging portions 31. When the holder 3 has attached the elongated body 10 to the support 2, the pair of engaging portions 31 are positioned to sandwich the elongated body 10 in the longitudinal direction X. In the pair of engaging portions 31, the respective engaging legs 312 are positioned on opposite sides of the elongated body 10 with the holding legs 313 in between. Hereinafter, to simplify the explanation of the positional relationship of the various parts of the holder 3, the side closer to the space between the pair of holding legs 313 in the longitudinal direction X with respect to the holding legs 313 will be referred to as the longitudinal inner side X1, and the side opposite to the longitudinal inner side X1 will be referred to as the longitudinal outer side X2.

[0067] 3-2.Regulation Department When the restricting portion is attached to the support 2 with the elongated body 10 sandwiched therebetween, the restricting portion restricts movement of the elongated body 10 in the attachment / detachment direction in which the support 2 and the holder 3 are attached / detached. In this embodiment, each of the plate-like body 32 and the connecting portion 33 shown in Figs. 1 to 3 is an example of the restricting portion.

[0068] As shown in FIG. 3 , the plate-like body 32, which is an example of a restricting portion, is connected to the holding legs 313. The plate-like body 32 is disposed between the pair of holding legs 313. In this manner, when the holder 3 and the elongated body 10 are attached to the support 2, the radial movement of the elongated body 10 is restricted by the attachment surface 214 of the base 21, the plate-like body 32 of the holder 3, and the pair of holding legs 313. With the support 2 and holder 3 illustrated in FIG. 3 , the movement of the elongated body 10 toward the upper side Z1 in the height direction is restricted by the attachment surface 214, the movement toward the inside X1 in the longitudinal direction is restricted by the pair of holding legs 313, and the movement toward the lower side Z2 in the height direction is restricted by the plate-like body 32. Therefore, the elongated body 10 is appropriately held to the structure W by the holder 3 and the support 2.

[0069] Preferably, each of the pair of engaging portions 31 has a plurality of engaging pieces 311 spaced apart in the attachment / detachment direction. The engaging portion 31 illustrated in FIG. 3 has two engaging pieces 311 spaced apart in the height direction Z. Therefore, the holder 3 illustrated in FIG. 3 can hold two types of elongated bodies 10 of different sizes. In detail, when the engaging piece 311 on the upper side Z1 in the height direction is engaged with the engaged piece 221, the larger of the two types of elongated bodies 10 can be held by the holder 3. On the other hand, when the engaging piece 311 on the lower side Z2 in the height direction is engaged with the engaged piece 221, the smaller of the two types of elongated bodies 10 can be held by the holder 3.

[0070] The plate-like body 32 is configured to be flexible and deformable along the outer shape of the elongated body 10. Therefore, when the engaging portion 31 is placed in the engaging position, the plate-like body 32 presses the elongated body 10 against the mounting surface 214 of the base 21. Therefore, the elongated body 10 is fixed in a stable state by the support 2 and the holder 3.

[0071] Preferably, the plate-like body 32 is formed continuously from each of the pair of holding legs 313 . A gap smaller than the outer dimension of the elongated body 10 in the longitudinal direction X is provided between the pair of plate-like bodies 32. According to this configuration, when the holder 3 is attached to the support 2, the plate-like bodies 32 are easily deformed to fit the outer shape of the elongated body 10.

[0072] Furthermore, preferably, the plate-like body 32 has a convex arc shape on the side away from the structure W (in this embodiment, the lower side Z2 in the height direction) in the attachment / detachment direction. Furthermore, as shown in FIGS. 1 and 3, the pair of plate-like bodies 32 are formed such that the central portion of the semi-cylindrical shape is slightly cut and raised toward the upper side Z1 in the height direction. When viewed from the short-side direction Y, the curvature of the plate-like body 32 is smaller than the curvature of the connecting portion 33, which will be described later. This configuration makes it easy to increase the area of ​​contact between the plate-like body 32 and the elongated body 10, so the plate-like body 32 can appropriately regulate the elongated body 10.

[0073] The connecting portion 33, which is an example of a restricting portion, is a portion that connects an end portion on the lower side Z2 in the height direction of one holding leg 313 to an end portion on the lower side Z2 in the height direction of another holding leg 313. The connecting portion 33 illustrated in Fig. 1 has an arc-shaped semi-cylindrical shape that is convex on the lower side Z2 in the height direction in a cross-sectional view.

[0074] Preferably, the connection portions 33 are integrated perpendicularly to a pair of side walls 315 that sandwich the space in which the elongated body 10 is placed, and function as ribs, thereby contributing to improving the strength of the holder 3. In this embodiment, there are a pair of connection portions 33. Each connection portion 33 is integrated with a pair of side walls 315 that are arranged on one side of the holding leg 313 in the short direction Y.

[0075] 4. Method of Using the Elongated Body Fixing Device of the First Embodiment A method of using the elongated body fixing device 1 of this embodiment will be described with reference to the drawings. Hereinafter, the procedure for attaching the elongated body 10 to the supporting device 2 using the holding device 3 after the supporting device 2 has been fixed to the structure W will be described with reference to Fig. 6. The procedure for removing the holding device 3 from the supporting device 2 will be described with reference to Fig. 7.

[0076] Before attaching the elongated body 10 to the support 2, the worker selects a holder 3 corresponding to the size of the elongated body 10. Such a holder 3 may have, for example, a pair of holding legs 313 whose distance between them is approximately equal to the outer diameter of the elongated body 10. The worker determines the position at which to attach the holder 3 relative to the support 2. In detail, the worker selects, from among multiple (three or more in this embodiment) engaged portions 22 formed on the support 2, an engaged portion 22 that is located in a position suitable for attaching the elongated body 10. The worker then engages the pair of engaging portions 31 of the holder 3 with the selected engaged portions 22.

[0077] As shown in the upper part of FIG. 6 , the worker places the elongated body 10 between the pair of engaging portions 31 of the holder 3, and then engages each of the pair of engaging portions 31 of the holder 3 with the engaged portion 22 of the support 2. Specifically, the pair of side walls 315, the flexible portion 314, the holding leg 313, and the engaging leg 312 of the engaging portion 31 are inserted into the engaged hole 222 of the engaged portion 22. In this case, the engaging piece 311 moves in the attachment / detachment direction (in this embodiment, upward in the height direction Z1). Then, the inclined portion of the engaging piece 311 is pressed against the engaged piece 221. As a result, a force is applied to both of the flexible portions 314 that hold the pair of engaging legs 312 in the inward longitudinal direction X1 via the inclined portions of the engaging leg 312 and the engaging piece 311. Therefore, both of the pair of flexible portions 314 deform from themselves as starting points such that each of the pair of engaging legs 312 is inclined inward in the longitudinal direction X1. Such deformation of the flexible portion 314 causes the engaging piece 311 to move to a non-engaged position where it fits into the engaged hole 222 , and as a result, the engaging piece 311 passes through the engaged hole 222 and is positioned inside the base 21 .

[0078] As shown in the lower part of FIG. 6, when the engaging piece 311 is positioned on the upper side Z1 in the height direction relative to the engaged piece 221, the force applied from the engaged piece 221 to the engaging leg 312 via the inclined portion of the engaging piece 311 is eliminated. As a result, the shape of the flexible portion 314 is restored so that the end of the engaging leg 312 on the lower side Z2 in the height direction moves outward in the longitudinal direction X2. In the example shown in the lower part of FIG. 6, the shape of the flexible portion 314 does not completely restore, but rather restores until the engaging leg 312 positioned in the engaged hole 222 abuts against the engaged piece 221. As a result, the engaging piece 311 is positioned at an engagement position where it abuts against the engaged piece 221 located on the lower side Z2 in the height direction relative to the engaged hole 222. Meanwhile, the plate-like body 32 moving toward the support 2 abuts against the surface of the elongated body 10 on the lower side Z2 in the height direction, which abuts against the mounting surface 214 of the base 21. The plate-like body 32 then deforms to fit the shape of the surface that it comes into contact with in the elongated body 10. As a result, the elongated body 10 is held by the attachment surface 214 of the support 2, and the pair of holding legs 313 and the plate-like body 32 of the holder 3.

[0079] When removing the elongated body 10 attached to the elongated body fixing device 1 shown in the upper part of Fig. 7 from the elongated body fixing device 1, the worker pinches the pair of holding pieces 31P of the holder 3 and deforms the flexible portion 314 toward the longitudinal inward direction X1, as shown in the lower part of Fig. 7. This causes the engaging legs 312 to tilt toward the longitudinal inward direction X1 from the flexible portion 314 as a starting point, and the engaging pieces 311 move in the height direction Z to a disengaged position where they fit into the engaged holes 222. In this state, the holder 3 and the elongated body 10 can be removed by moving the holder 3 to the removal side in the attachment / detachment direction (in this embodiment, toward the lower side Z2 in the height direction).

[0080] As described above, the elongated body fixing device 1 of this embodiment has a high degree of freedom in the position and size of the elongated body 10 that can be fixed to the structure W, and the elongated body 10 can be attached and detached without the use of tools.

[0081] 5. Second embodiment of elongated body fixing device The elongated body fastener 1 of the second embodiment differs from the first embodiment in that the support device 2 expands and contracts in the height direction Z. Hereinafter, with reference to Figures 10 and 11, the differences between the elongated body fastener 1 of the second embodiment and the first embodiment will be mainly described, and the same points between the second embodiment and the first embodiment will not be described. In addition, after describing the structure of the elongated body fastener 1 of the second embodiment, a method of using the elongated body fastener 1 of the second embodiment will be described.

[0082] 5-1. Structure of the elongated body fixing device of the second embodiment The elongated body fixing device 1 of the second embodiment differs from that of the first embodiment in the structure of the fixing base 23 provided in the support device 2. In this embodiment, the fixing base 23 is disposed between the structure W and the base 21, as in the first embodiment. However, in this embodiment, the fixing base 23 has an expandable structure 233 that expands and contracts in the height direction Z, as shown in FIG. 10 . With this configuration, the distance in the height direction Z from the structure W to the engaged portion 22 can be adjusted by expanding and contracting the expandable structure 233. Therefore, the worker can adjust the distance in the height direction Z from the structure W to the elongated body 10 and fix it to the structure W using a single type of fixing base 23.

[0083] The telescopic structure 233 includes a first fixable body 4 fixed to the structure W and a second fixable body 5 fixed to the base 21. The first fixable body 4 and the second fixable body 5 are connected so that their relative positions in the height direction Z (hereinafter simply referred to as "relative positions") are movable. Therefore, an operator can appropriately adjust the relative positions of the first fixable body 4 and the second fixable body 5. By adjusting the relative positions of the first fixable body 4 and the second fixable body 5, the relative positions of the structure W and the base 21 in a state in which the first fixable body 4 is fixed to the structure W and the second fixable body 5 is fixed to the base 21 are adjusted.

[0084] The first fixed body 4 has a first fixed portion 41 that is fixed to the structure W, and a first connecting portion 42 that extends from the first fixed portion 41 along the height direction Z toward the second fixed portion 51. In this embodiment, as shown in Fig. 10, the first fixed portion 41 is disposed on the upper side Z1 in the height direction relative to the second fixed portion 51, and therefore the first connecting portion 42 extends from the first fixed portion 41 to the lower side Z2 in the height direction. The first fixed portion 41 is fixed to the structure W, for example, by bonding it to the structure W with an adhesive or by fastening it to the structure W with a fastening part such as a screw.

[0085] In this embodiment, the first fixed portion 41 has a plate shape extending along the longitudinal direction X, and the first connecting portion 42 has a plate shape extending along the height direction Z. The first fixed portion 41 is fixed to the structure W with its wide surface abutting the structure W, and the wide surface of the plate-like first connecting portion 42 faces the longitudinal direction X. In the example shown in FIG. 10 , the first fixed portion 41 and the first connecting portion 42 have an integral structure. Therefore, the structure connecting the first fixed portion 41 and the first connecting portion 42 is simplified.

[0086] The second fixed body 5 has a second fixed part 51 fixed to the base 21 and a second connecting part 52 extending from the second fixed part 51 toward the first fixed part 41 along the height direction Z. In this embodiment, the second fixed part 51 is disposed on the lower side Z2 in the height direction relative to the first fixed part 41, and therefore the second connecting part 52 extends from the second fixed part 51 to the upper side Z1 in the height direction. The second fixed part 51 is fixed to the base 21 via the detachable part 232 described in the first embodiment. The detachable part 232 has four claws that engage with the base 21, as in the first embodiment. In the example shown in FIG. 10, the second fixed part 51 and the second connecting part 52 are integrally formed.

[0087] In this embodiment, the second fixed portion 51 has a plate shape extending along the longitudinal direction X. The second fixed portion 51 is arranged so that its wide surface abuts against the upper part of the base 21. The second connecting portion 52 has a plate shape extending along the height direction Z from the second fixed portion 51. The wide surface of the second connecting portion 52 faces the longitudinal direction X. In this embodiment, the pair of second connecting portions 52 are arranged with a gap between them in the longitudinal direction X. The gap between the pair of second connecting portions 52 is a distance approximately equal to the thickness of the first connecting portion 42 in the longitudinal direction X. The first connecting portion 42 is arranged between the pair of second connecting portions 52.

[0088] The first connecting portion 42 and the second connecting portion 52 are connected by maintaining their relative positions. For this reason, in this embodiment, the extension / contraction structure 233 further includes an extension / contraction restricting structure 6 that restricts relative movement between the first connecting portion 42 and the second connecting portion 52. In this embodiment, the extension / contraction restricting structure 6 is a structure that causes the first connecting portion 42 to engage with the second connecting portion 52 in the height direction Z, and includes a first restricting portion 61 provided in the first connecting portion 42 and a second restricting portion 62 provided in the second connecting portion 52.

[0089] In the example shown in FIGS. 10 and 11 , the first restricting portion 61 is a convex portion protruding from the first connecting portion 42 to at least one side in the longitudinal direction X. The second restricting portion 62 is a recessed portion provided on a surface of the second connecting portion 52 facing the first restricting portion 61. The second restricting portion 62 has a shape that can accommodate at least a portion of the first restricting portion 61. The second restricting portion 62 has a pair of surfaces that are spaced apart in the height direction Z, and these surfaces restrict movement of the first restricting portion 61 in the height direction Z. For example, the first restricting portion 61 abuts against the surface of the pair of surfaces included in the second restricting portion 62 that is on an upper side Z1 in the height direction, thereby restricting movement of the first restricting portion 61 toward the upper side Z1 in the height direction. On the other hand, the first restricting portion 61 abuts against the surface of the pair of surfaces included in the second restricting portion 62 that is on a lower side Z2 in the height direction, thereby restricting movement of the first restricting portion 61 toward the lower side Z2 in the height direction.

[0090] In this embodiment, the first restricting portions 61 protrude from the first connecting portion 42 on both sides in the longitudinal direction X, and the second restricting portions 62 are provided on both opposing surfaces of the pair of second connecting portions 52. The second restricting portion 62 provided on one second connecting portion 52 is arranged so as to be at the same position in the height direction Z as the second restricting portion 62 provided on the other second connecting portion 52. With this configuration, relative movement between the first connecting portion 42 and the second connecting portion 52 is restricted at two different positions in the longitudinal direction X, making it easy to maintain a stable position of the first connecting portion 42 relative to the second connecting portion 52.

[0091] As described above, it is preferable that a plurality of sets of the first connecting portion 42 and the pair of second connecting portions 52 are provided at intervals in the longitudinal direction X. With this configuration, bending deformation of the first connecting portion 42 around the connection portion of the first connecting portion 42 with the first fixed portion 41 can be suppressed. This makes it easier to stabilize the position of the elongated body 10. In particular, it is preferable that two sets of the first connecting portion 42 and the pair of second connecting portions 52 are provided. With this configuration, bending deformation of the first connecting portion 42 can be suppressed to the minimum necessary, and manufacturing is easier than when there are three or more sets of the first connecting portion 42 and the pair of second connecting portions 52.

[0092] Preferably, as shown in Figures 10 and 11, the expansion and contraction structure 233 expands and contracts by a predetermined amount. For example, when a heat insulating material is disposed between the structure W and the base 21, the expansion and contraction amount is set in consideration of the required heat insulating performance. The expansion and contraction amount may vary depending on the position in the height direction Z, or may be the same. In order for the expansion and contraction structure 233 to expand and contract by the predetermined expansion and contraction amount, a plurality of first restricting portions 61 or second restricting portions 62 are provided at intervals in the height direction Z. The distance in the height direction Z between the first restricting portions 61 or second restricting portions 62 adjacent in the height direction Z (restriction interval DL) is the expansion and contraction amount.

[0093] In this embodiment, as shown in Figures 10 and 11, one first restricting portion 61 is provided and a plurality of second restricting portions 62 are provided. Specifically, three second restricting portions 62 are provided at intervals in the height direction Z. In Figures 10 and 11, the distance from the center of one second restricting portion 62 in the height direction Z to the center of the second restricting portion 62 adjacent to this second restricting portion 62 in the height direction Z is illustrated as the restricting distance DL. Furthermore, if the distance from the surface of the first fixed portion 41 facing the second fixed portion 51 to the surface of the second fixed portion 51 facing the first fixed portion 41 is defined as the fixing base height L, the fixing base height L shown in Figures 10 and 11 can be adjusted in three stages.

[0094] 5-2. Method of using the elongated body fixing device of the second embodiment The method of using the elongated body fixture 1 of the second embodiment includes the step of adjusting the fixture base height L of the fixture base 23, as shown in Figures 10 and 11. The step of adjusting the fixture base height L can be performed either before or after attaching the elongated body 10 to the elongated body fixture 1, allowing the elongated body 10 to be properly attached to the elongated body fixture 1. However, it is preferable to perform the step of adjusting the fixture base height L before attaching the elongated body 10 to the elongated body fixture 1. This is because the adjustment of the fixture base height L can be easily performed when the elongated body 10 is not attached to the base 21.

[0095] In the process of adjusting the fixing base height L, the first connecting portion 42 and the second connecting portion 52 are connected so that the extension / contraction restricting structure 6 restricts relative movement between the first connecting portion 42 and the second connecting portion 52. In this embodiment, the first connecting portion 42 and the second connecting portion 52 are arranged as shown in FIG. 10 so that the first restricting portion 61 and the second restricting portion 62 engage with each other. The example shown in FIG. 10 shows the case where the fixing base height L is at its shortest. In this case, the first restricting portion 61 engages with the second restricting portion 62 that is closest to the second fixed portion 51.

[0096] When changing the fixed base height L, the relative positions of the first connecting portion 42 and the second connecting portion 52 are changed when the extension / contraction restricting structure 6 restricts the first connecting portion 42 and the second connecting portion 52. In this embodiment, as shown in FIG. 11 , the second restricting portion 62 with which the first restricting portion 61 engages is changed. FIG. 11 shows an example of a state in which the fixed base height L is increased by the amount of extension / contraction compared to the fixed base height L illustrated in FIG. 10 . When changing the state of the fixed base 23 from the state of FIG. 10 to the state of FIG. 11 , at least one of the first connecting portion 42 and the second connecting portion 52 is moved in the short-side direction Y to release the engagement between the first restricting portion 61 and the second restricting portion 62. In this case, the worker temporarily separates the first fixed body 4 and the second fixed body 5 by moving them in the short-side direction Y until they are spaced apart from each other. Then, the worker re-engages the first restricting portion 61 with a second restricting portion 62 that is different from the second restricting portion 62 that was engaged with the first restricting portion 61 before the engagement between the first restricting portion 61 and the second restricting portion 62 was released. This adjusts the fixed base height L. Preferably, the fixed base 23 is attached to the structure W after the fixed base height L of the fixed base 23 to which the base 21 is attached has been adjusted. In this way, the adjustment of the fixed base height L can be easily performed without the fixed base 23 being attached to the structure W.

[0097] 6. Third embodiment of elongated body fixing device The elongated body fixation device 1 of the third embodiment differs from the second embodiment in that the extension / contraction structure 233 extends and contracts without separating the first fixation target 4 and the second fixation target 5. With this configuration, the support device 2 does not separate into multiple parts when the worker uses it, making it easier for the worker to manage the support device 2. Hereinafter, with reference to FIGS. 12 to 17, differences between the third embodiment and the second embodiment will be mainly described, and similarities between the third embodiment and the second embodiment will not be described. In addition, after describing the structure of the elongated body fixation device 1 of the third embodiment, a method of using the elongated body fixation device 1 of the third embodiment will be described.

[0098] 6-1. Structure of the elongated body fixing device of the third embodiment

[0099] In this embodiment, similar to the second embodiment, the first connecting portion 42 and the second connecting portion 52 maintain their relative positions with the first restricting portion 61 and the second restricting portion 62 engaged with each other. In this embodiment, at least one of the first connecting portion 42 and the second connecting portion 52 deforms so that the first restricting portion 61 and the second restricting portion 62 move away from their engaged state. With this configuration, the engagement between the first restricting portion 61 and the second restricting portion 62 can be released without separating the first fixed body 4 and the second fixed body 5.

[0100] 12 and 13, only the first connecting portion 42 deforms to release the engagement between the first restricting portion 61 and the second restricting portion 62. The first connecting portion 42 is plate-shaped with a wide surface facing the longitudinal direction X and is disposed adjacent to one side of the second connecting portion 52 in the longitudinal direction X. The first fixed portion 41 is connected to an end of the first connecting portion 42 on an upper side Z1 in the height direction, and the first restricting portion 61 is disposed on a lower side Z2 in the height direction relative to the first fixed portion 41. More specifically, as illustrated in FIG. 13, the first restricting portion 61 is provided at an end of the first connecting portion 42 on the lower side Z2 in the height direction. The first restricting portion 61 illustrated in FIG. 13 protrudes from the first connecting portion 42 toward the second connecting portion 52 along the longitudinal direction X. The first connecting portion 42 is bent and deformed around one end portion, which is the connection portion with the first fixed portion 41, in a direction such that the other end portion is separated from the second connecting portion 52. In the example shown in Fig. 13, the second connecting portion 52 is a plate-shaped member with a wide surface facing the longitudinal direction X, and the second restricting portion 62 is a through-hole that penetrates the second connecting portion 52 in the longitudinal direction X. The first restricting portion 61 and the second restricting portion 62 are engaged with each other by inserting the first restricting portion 61 into the second restricting portion 62.

[0101] 13, the pair of second connection portions 52 are arranged at an interval in the short-side direction Y. The second restriction portion 62 is provided on both of the pair of second connection portions 52, and the first connection portion 42 is provided with a pair of first restriction portions 61 that engage with the pair of second restriction portions 62, respectively. The second restriction portion 62 provided on one of the pair of second connection portions 52 is arranged so as to be at the same position in the height direction Z as the second restriction portion 62 provided on the other of the pair of second restriction portions 62. According to this configuration, the pair of first restriction portions 61 each engage with the pair of second restriction portions 62 at different positions in the short-side direction Y, thereby stabilizing the orientation of the first connection portion 42 around the longitudinal direction X.

[0102] As described above, it is preferable that a plurality of sets of a first connecting portion 42 and a pair of second connecting portions 52 are provided at intervals in the longitudinal direction X. In particular, it is preferable that two sets of a first connecting portion 42 and a pair of second connecting portions 52 are provided. In this case, it is preferable that the first connecting portion 42 is deformable to release the engagement between the first restricting portion 61 and the second restricting portion 62, and that the pair of second connecting portions 52 included in each of the two sets are arranged to sandwich the two pairs of first connecting portions 42 therebetween. According to this configuration, a structure can be achieved in which the engagement between the first restricting portion 61 and the second restricting portion 62 can be released by pressing the two pairs of first connecting portions 42 simultaneously, making it easier to adjust the fixing base height L.

[0103] 6-2. Telescopic auxiliary structure In this embodiment, the telescopic structure 233 further includes an extension / retraction auxiliary structure 7 that assists in the extension / retraction of the extension / retraction structure 233. The extension / retraction auxiliary structure 7 includes a guide rail 71, a pressed portion 72, a limiting piece 73, and a restricting piece 74. The guide rail 71 guides the relative positional movement of the first fixed body 4 and the second fixed body 5 in the height direction Z. The pressed portion 72 is provided to facilitate deformation of the first connecting portion 42. The restricting piece 73 limits excessive deformation of the first connecting portion 42. The restricting piece 74 restricts separation of the first connecting portion 42 and the second connecting portion 52. Note that the guide rail 71, the pressed portion 72, the limiting piece 73, and the restricting piece 74 may all be included in the extension / retraction auxiliary structure 7, or only some of them may be included in the extension / retraction auxiliary structure 7.

[0104] [Guide rail] The guide rail 71 guides the relative movement of the second connection portion 52 in the height direction Z with respect to the first connection portion 42. As shown in FIG. 13 , in this embodiment, the guide rail 71 has a first rail portion 711 extending from the first fixed portion 41 toward the second fixed portion 51 along the height direction Z, and a second rail portion 712 extending from the second fixed portion 51 toward the first fixed portion 41 along the height direction Z. The first rail portion 711 and the second rail portion 712 engage with each other so that relative movement in the longitudinal direction X and the lateral direction Y is restricted. The first rail portion 711 includes a first surface 71A facing the longitudinal direction X and a second surface 71B facing the lateral direction Y. Although not shown in detail, the second rail portion 712 forms an insertion space into which the first rail portion 711 can be inserted from an upper side Z1 in the height direction. The insertion space is surrounded by walls that abut both the first surface 71A and the second surface 71B. According to this configuration, when the first rail portion 711 and the second rail portion 712 are engaged with each other, the relative positions of the first connecting portion 42 and the second connecting portion 52 can be changed in a stable posture. In the example shown in FIG. 13 , the dimension of the first rail portion 711 in the height direction Z is larger than that of the first connecting portion 42, and the dimension of the second rail portion 712 in the height direction Z is larger than that of the second connecting portion 52. Therefore, when the first fixed body 4 and the second fixed body 5 are connected, the first rail portion 711 and the second rail portion 712 are engaged with each other.

[0105] [Pressure receiving part] The pressed portion 72 is provided on the side of the first connection portion 42 or the second connection portion 52 that is more likely to deform. Specifically, the pressed portion 72 protrudes from either the first connection portion 42 or the second connection portion 52 toward the other of the first connection portion 42 or the second connection portion 52. The pressed portion 72 is disposed at a position that does not overlap with the first connection portion 42 or the second connection portion 52 when viewed from at least one of the longitudinal direction X and the lateral direction Y. The protruding surface of the pressed portion 72 is recessed and curved to fit the surface shape of the finger. The pressed portion 72 illustrated in FIG. 13 protrudes from an end of the first connection portion 42 on the lower side Z2 in the height direction toward the second connection portion 52 along the longitudinal direction X. The dimensions of the pressed portion 72 in the height direction Z and the lateral direction Y are set to correspond to the size of the finger. In addition, when viewed from the longitudinal direction X, the pressed portion 72 is disposed between a pair of second connecting portions 52 that are disposed at an interval in the short direction Y. In addition, the protruding surface of the pressed portion 72 is disposed so as to protrude from the second connecting portions 52 on the opposite side to the first connecting portion 42 in the longitudinal direction X. With this configuration, the worker can deform the first connecting portion 42 without being hindered by the second connecting portions 52.

[0106] [Restriction piece] The limiting piece 73 is provided at a position where it will be positioned by deformation of the first connecting portion 42 and the second connecting portion 52. That is, when the first connecting portion 42 deforms, the limiting piece 73 is provided at a position spaced apart from the first connecting portion 42 and at a position where it will be positioned by deformation of the first connecting portion 42. On the other hand, when the second connecting portion 52 deforms, the limiting piece 73 is provided at a position spaced apart from the second connecting portion 52 and at a position where it will be positioned by deformation of the second connecting portion 52. The distance between the first connecting portion 42 or the second connecting portion 52 and the limiting piece 73 is determined according to the allowable deformation amount of the first connecting portion 42 or the second connecting portion 52. This configuration prevents the first connecting portion 42 or the second connecting portion 52 from deforming beyond the allowable amount. The allowable amount is determined, for example, as an upper limit of the deformation amount at which plastic deformation of the first connecting portion 42 or the second connecting portion 52 begins. This allows the first connecting portion 42 and the second connecting portion 52 to maintain their appropriate shapes.

[0107] The limiting piece 73 illustrated in FIG. 14 is disposed on a side of the first connecting portion 42 that is farther from the second connecting portion 52 in the longitudinal direction X than the first connecting portion 42 because the first connecting portion 42 deforms. The restricting piece 74 extends from the first fixed portion 41 toward the second fixed portion 51 along the height direction Z. The dimension of the restricting piece 74 in the height direction Z is greater than the dimension from the first fixed portion 41 to the end of the first connecting portion 42 on the lower side Z2 in the height direction. This configuration limits the amount of movement of the free end of the first connecting portion 42, which is cantilevered relative to the first fixed portion 41. This allows the distance between the first connecting portion 42 and the restricting piece 73 to be narrower than in a configuration in which the first connecting portion 42 is disposed midway between the free end and the fixed end of the first connecting portion 42. This facilitates miniaturization of the fixing base 23.

[0108] [Regulation piece] The restricting piece 74 restricts relative movement of the first connecting portion 42 and the second connecting portion 52 beyond a certain limit in a direction in which the first connecting portion 42 and the second connecting portion 52 separate when the first connecting portion 42 and the second connecting portion 52 are coupled together. In the present embodiment, as shown in FIG. 15 , when the first connecting portion 42 and the second connecting portion 52 are coupled together, the restricting piece 74 is spaced apart from the first restricting portion 61 and the second restricting portion 62 in the height direction Z and is disposed on the side in the height direction Z where the first connecting portion 42 and the second connecting portion 52 separate. In the example shown in FIGS. 14 and 15 , the restricting piece 74 is disposed on the upper side Z1 in the height direction relative to the first restricting portion 61 and the second restricting portion 62. With this configuration, the first connecting portion 42 and the second connecting portion 52 are prevented from coming off while allowing relative movement between them in the height direction Z.

[0109] The restricting piece 74 has a restricting surface 741 that restricts movement of the first connecting portion 42 or the second connecting portion 52 in the height direction Z, and a guide surface 742. The guide surface 742 is a surface that guides movement of the first connecting portion 42 or the second connecting portion 52 so that the first connecting portion 42 and the second connecting portion 52 change from a separated state to a connected state. In this embodiment, the restricting piece 74 is provided at a position on the second fixed body 5 where it is difficult to deform so that its relative position with respect to the second connecting portion 52 is fixed. With this configuration, the position of the guide surface 742 is stable with respect to the second fixed body 5, and therefore the guide surface 742 can appropriately guide the deformation of the first connecting portion 42 compared to a configuration in which the guide surface 742 deforms due to contact with the first restricting portion 61.

[0110] The restricting surface 741 is disposed at a position overlapping one of the first connecting portion 42 and the second connecting portion 52 that deforms as viewed from the height direction Z, and is spaced apart in the height direction Z from the other of the first connecting portion 42 and the second connecting portion 52. The distance between the restricting surface 741 and the other of the first connecting portion 42 and the second connecting portion 52 is larger than the dimension in the height direction Z of the first restricting portion 61 or the second restricting portion 62 provided on the deformable one of the first connecting portion 42 and the second connecting portion 52. In this embodiment, the restricting surface 741 restricts movement of the first restricting portion 61 upward in the height direction Z1. The restricting surface 741 illustrated in FIG. 14 is disposed at a position overlapping the first connecting portion 42 as viewed from the height direction Z. The distance in the height direction Z between the second connecting portion 52 and the restricting surface 741 is larger than the dimension in the height direction Z of the first restricting portion 61. According to this configuration, when the first fixed body 4 and the second fixed body 5 are changed from a separated state to a connected state, the first regulating portion 61 can pass between the regulating surface 741 and the second connecting portion 52 and move to a position overlapping with the regulating surface 741 when viewed from the height direction Z.

[0111] The guide surface 742 is provided on the side of the restriction surface 741 where the first connection portion 42 and the second connection portion 52 are separated in the height direction Z. In the example shown in FIGS. 14 and 15 , the guide surface 742 is provided on the upper side Z1 in the height direction relative to the restriction surface 741. When the first connection portion 42 and the second connection portion 52 are changed from a separated state to a connected state, the guide surface 742 deforms either the first connection portion 42 or the second connection portion 52, whichever is to be deformed, into a shape necessary for being positioned on the lower side Z2 in the height direction relative to the restriction surface 741. In this embodiment, the guide surface 742 deforms the first connection portion 42.

[0112] The guide surface 742 is inclined from one of the first restricting portion 61 and the second restricting portion 62 that overlaps with the restricting surface 741 toward the other when viewed from the height direction Z. The inclination of the guide surface 742 is formed such that the guide surface 742 approaches the other of the first restricting portion 61 and the second restricting portion 62 from one that overlaps with the restricting surface 741 as the first connecting portion 42 and the second connecting portion 52 approach each other in the height direction Z when viewed from a position where the first connecting portion 42 and the second connecting portion 52 appear adjacent to each other. In this embodiment, the guide surface 742 is inclined from the first restricting portion 61 to the second restricting portion 62 as it approaches the lower side Z2 in the height direction when viewed from the short direction Y. The guide surface 742 illustrated in FIG. 14 is continuously connected to the restricting surface 741 at an end portion on the side closer to the second restricting portion 62 along the longitudinal direction X when viewed from the short direction Y.

[0113] 6-3. Method of using the elongated body fixing device of the third embodiment Unlike the first embodiment, the method of using the elongated body fixation device 1 of the third embodiment includes a connecting step of connecting the first connecting portion 42 and the second connecting portion 52 of the fixing base 23, and a step of adjusting the height of the fixing base 23. The step of adjusting the height of the fixing base 23 can be performed more easily than in the second embodiment. Hereinafter, with reference to Figures 14 to 16, the differences between the method of using the elongated body fixation device 1 of the third embodiment and the first and second embodiments will be mainly described, and a description of the same points as in the first and second embodiments will be omitted.

[0114] 14 , in the connecting step, the first connecting portion 42 and the second connecting portion 52 are brought closer together in the height direction Z with the first restricting portion 61 or the second restricting portion 62 in contact with the guide surface 742. In this manner, the deforming sides of the first connecting portion 42 and the second connecting portion 52 deform along the guide surface 742. In this embodiment, the first restricting portion 61 is in contact with the guide surface 742, and the first connecting portion 42 is deformed around the connection portion with the first fixed portion 41 toward a position where the tip of the first connecting portion 42 overlaps with the second connecting portion 52 as viewed in the height direction Z.

[0115] When the first connecting portion 42 or the second connecting portion 52 is further brought closer to each other while the first connecting portion 42 or the second connecting portion 52 is in a deformed state, the first restricting portion 61 or the second restricting portion 62 moves away from the guide surface 742, and the first connecting portion 42 or the second connecting portion 52 returns to its pre-deformation shape. The first restricting portion 61 or the second restricting portion 62 is then disposed in a position overlapping the restricting surface 741 as viewed from the height direction Z. In this embodiment, the first connecting portion 42, which has returned to its pre-deformation shape by bringing the first connecting portion 42 and the second connecting portion 52 closer to each other, overlaps the guide surface 742 as viewed from the height direction Z and is disposed in a position on the lower side Z2 in the height direction relative to the guide surface 742. Meanwhile, even if an attempt is made to move the first connecting portion 42 upward in the height direction Z1 relative to the restricting surface 741, the movement of the first connecting portion 42 is restricted as the first restricting portion 61 abuts against the restricting surface 741.

[0116] In the process of adjusting the height of the fixed base 23, the first connecting portion 42 and the second connecting portion 52 are connected so that the extension / contraction restricting structure 6 maintains a state in which the relative movement of the first connecting portion 42 and the second connecting portion 52 in the height direction Z is restricted. In this embodiment, the first connecting portion 42 and the second connecting portion 52 are arranged as shown in FIG. 15 so that the first restricting portion 61 and the second restricting portion 62 engage with each other. The example shown in FIG. 15 shows a case in which the height of the fixed base 23 is at its shortest. In this case, the first restricting portion 61 engages with the second restricting portion 62 that is closest to the second fixed portion 51.

[0117] When the height of the fixed base 23 is changed, the position at which the extension / contraction restricting structure 6 restricts the first connection portion 42 and the second connection portion 52 is changed. In this embodiment, as shown in FIG. 16 , the second restriction portion 62 with which the first restriction portion 61 engages is changed. FIG. 16 shows an example of a state in which the height of the fixed base 23 is increased compared to the height of the fixed base 23 illustrated in FIG. 15 . When changing the state of the fixed base 23 from the state of FIG. 15 to the state of FIG. 16 , in order to release the engagement between the first restriction portion 61 and the second restriction portion 62, the worker presses the surface of the pressed portion 72 to deform the first connection portion 42 or the second connection portion 52 toward the restricting piece 73. In this embodiment, when the worker presses the pressed portion 72, the first connection portion 42 is deformed so that the first restriction portion 61 moves away from the second restriction portion 62. Then, while pressing the pressed portion 72, the worker relatively moves the first connecting portion 42 and the second connecting portion 52 along the height direction Z, and aligns the position of the first restricting portion 61 in the height direction Z with the second restricting portion 62 that is different from the second restricting portion 62 that was engaged with the first restricting portion 61 before the first connecting portion 42 and the second connecting portion 52 were separated. After this, the worker releases the pressure on the pressed portion 72, and the first restricting portion 61 is housed in the second restricting portion 62 that is different from the state in FIG. 15 , and the relative movement between the first connecting portion 42 and the second connecting portion 52 is restricted.

[0118] 7. Other embodiments (1) In the above embodiment, when attaching the elongated body 10 to the elongated body fixing device 1, the worker places the elongated body 10 between the pair of holding legs 313 and then engages the elongated body 10 with the pair of engaged portions 22 of the support device 2. However, the worker may place the elongated body 10 between the pair of holding legs 313 after the pair of engaging portions 31 of the holder 3 have been inserted to a certain extent into the pair of engaged holes 222, respectively.

[0119] (2) In the above embodiment, when attaching the elongated body 10 to the elongated body fixture 1, the engaging piece 311 is positioned in the engagement position by utilizing the deformation of the flexible portion 314 caused by contact between the inclined portion of the engaging piece 311 and the engaged piece 221. However, the worker may engage the engaging portion 31 with the engaged portion 22 in a state in which the flexible portion 314 is deformed so that the engaging piece 311 fits into the engaged hole 222. In this way, the worker can insert the engaging portion 31 into the engaged hole 222 without resistance.

[0120] (3) In the above embodiment, one of the pair of fixed portions 23P is fixed to the structure W with an adhesive or the like, and the other of the pair of fixed portions 23P is fixed to the base 21 via the detachable portion 232. However, each of the pair of fixed portions 23P may be fixed by any method as long as it is fixed to the structure W or the base 21. For example, the fixed portion 23P may be fixed to the structure W via another component. Alternatively, the fixed portion 23P may be fixed to the base 21 with an adhesive or the like.

[0121] (4) In the first embodiment, the intermediate portion 23C of the platform portion 231 in the fixed base 23 is described as being plate-shaped and extending in the height direction Z. However, the intermediate portion 23C may be formed by forming a recess in the short-side direction Y. Furthermore, a through-hole, a groove, or the like may be further formed in the intermediate portion 23C. With this configuration, the area of ​​thermal insulation defect can be made smaller.

[0122] (5) In the above embodiment, the holder 3 has been described as having the plate-shaped body 32 and the connecting portion 33 as the restricting portion. However, the restricting portion may have any structure as long as it can restrict the movement of the elongated body 10 in the attachment / detachment direction. For example, the holder 3 may have a structure including only either the plate-shaped body 32 or the connecting portion 33.

[0123] (6) In the above embodiment, it has been described that the shape of the flexible portion 314 is not completely restored when the engaging portion 31 is engaged with the engaged portion 22. However, the shape of the flexible portion 314 may be completely restored when the engaging portion 31 is engaged with the engaged portion 22. For example, the structure of the flexible portion 314 or its surrounding area may be set so that the engaging leg 312 does not come into contact with the engaged piece 221 when the engaging portion 31 is engaged with the engaged portion 22.

[0124] (7) In the above embodiment, it was explained that there were more engaging portions 31 than engaged portions 22. However, without being limited to such a configuration, this specification also discloses an elongated body fixation device 1 in which the number of engaging portions 31 is the same as the number of engaged portions 22, and an elongated body fixation device 1 in which the number of engaging portions 31 is fewer than the engaged portions 22. Such an elongated body fixation device 1 has the following configuration.

[0125] A long body fixing device 1 for fixing a long body 10 to a structure W, A support 2 fixed to the structure W and a holder 3 attached to the support 2 with the elongated body 10 sandwiched therebetween, The support 2 includes a base 21 that is arranged at an interval in the longitudinal direction X and has an engaged portion 22 that can be engaged with an engaging portion 31 of the holder 3 .

[0126] (8) In the above embodiment, the holder 3 has been described as having a pair of engaging portions 31. However, the number of engaging portions 31 is not limited to a pair, and may be one or three or more. For example, when there is one engaging portion 31, one end of the holder 3 (the end not provided with the engaging portion 31) may be integrally connected to the support 2.

[0127] (9) In the above embodiment, the holder 3 is described as attaching one elongated body 10 to the support 2. However, the number of elongated bodies 10 attached to the support 2 by the holder 3 is not limited to one. The holder 3 may be configured to attach multiple elongated bodies 10 to the support 2. For example, in the case of a holder 3 having a pair of engaging portions 31, the spacing between the pair of engaging portions 31 may be set so that multiple elongated bodies 10 can be positioned between the pair of engaging portions 31. Furthermore, in the case of a holder 3 having three or more engaging portions 31, the spacing between each pair of engaging portions 31 may be set so that one or multiple elongated bodies 10 can be positioned between adjacent pairs of engaging portions 31. In addition, the holder 3 may be configured so that a partition is provided between the pair of engaging portions 31 and one or multiple elongated bodies 10 are positioned on both sides of the partition in the longitudinal direction X.

[0128] (10) In the above embodiment, it was explained that the holder 3 can be deformed by the force of the fingers into a position that disengages the engaged portion 22 from the engaging piece 311. However, without being limited to such a configuration, this specification also discloses an elongated body fixation device 1 that includes a holder 3 that requires a force stronger than that of the fingers to deform into a position that disengages the engaged portion 22 from the engaging piece 311. Such an elongated body fixation device 1 has the following configuration.

[0129] A long body fixing device 1 for fixing a long body 10 to a structure W, A support 2 fixed to the structure W and a holder 3 attached to the support 2 with the elongated body 10 sandwiched therebetween, The holder 3 has an engaging portion 31 that can engage with a plurality of engaged portions 22 provided on the support 2, The engaging portion 31 has an engaging piece 311 that restricts movement of the holder 3 toward the side where it is removed from the support 2 by engaging with the engaged portion 22 .

[0130] (11) In the first embodiment, the fixing base 23 has been described as having the intermediate portion 23C. However, the fixing base 23 may have a structure in which the pair of fixing portions 23P are integrated without the intermediate portion 23C.

[0131] (12) In the second and third embodiments, the first fixed portion 41 is described as being integral with the first connecting portion 42, and the second fixed portion 51 is described as being integral with the second connecting portion 52. However, the first fixed portion 41 may be a separate structure from the first connecting portion 42. Similarly, the second fixed portion 51 may be a separate structure from the second connecting portion 52.

[0132] (13) In the second and third embodiments, the first restricting portion 61 and the second restricting portion 62 are described as engaging with each other. However, the first restricting portion 61 and the second restricting portion 62 may have a structure other than an engaging structure as long as they can restrict relative movement of each other in the height direction Z. For example, the first restricting portion 61 and the second restricting portion 62 may be fastened with a fastening part such as a bolt to fix their relative positions in the height direction Z.

[0133] (14) In the second and third embodiments, it has been described that the stretchable structure 233 stretches and contracts in stages according to the structure of the stretch-restricting structure 6. However, the stretchable structure 233 may be structured to stretch and contract continuously.

[0134] (15) The configurations disclosed in the above-described embodiments (including the above-described embodiments and other embodiments; the same applies hereinafter) can be applied in combination with configurations disclosed in other embodiments, as long as no contradiction occurs. Regarding other configurations, the embodiments disclosed in this specification are illustrative in all respects and can be appropriately modified within the scope of the present disclosure. [Industrial Applicability]
