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 holder (exterior restriction member B) of the elongate body fixing device (mounting jig) described in Patent Document 1 requires a tool to remove it from the support (base A) that can hold it. Therefore, when changing the position of the holder attached to the support, a tool is required to remove the holder from the support. The work of preparing a tool to change the position of the holder attached to the support reduces the efficiency of the overall work of fixing the elongate body to a structure. For this reason, it is desirable to realize a elongate body fixing device that can efficiently perform the entire work of fixing the elongate 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 holder that is attached to the support and sandwiches the elongated body, the holder having a pair of engaging portions that can engage with a plurality of engaged portions provided on the support, and the pair of engaging portions each have an engaging piece that engages with the engaged portion to restrict movement of the holder toward the side that removes it from the support, and the holder can be deformed into a position that releases the engagement between the engaged portion and the engaging piece by the force of the fingers.

[0008] According to this configuration, when an operator positions the holder at the attachment position on the support, the engaging portion engages with the engaged portion, and conversely, when the operator deforms the engaging legs of the holder attached to the support with their fingers, the engagement between the engaging portion and the engaged portion is released. Therefore, the operator does not need to use tools to remove the holder from the support, and the entire process of fixing the elongated body to the structure can be performed efficiently.

[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 aspect, the engagement portion further has an engagement leg on which the engagement piece is formed and a retaining leg that retains the engagement leg, the elongated body is arranged between the pair of retaining legs, the engagement leg is arranged on the opposite side of the elongated body across the retaining leg, and is capable of flexibly deforming in the direction approaching the retaining leg.

[0011] According to this configuration, each of the pair of engaging legs is positioned outside the space between the pair of holding legs, allowing the worker to grasp the pair of engaging legs with the fingers of one hand. In this state, narrowing the distance between the fingers deforms the pair of engaging legs, positioning the engaging portion at a position where the engaging portion disengages from the engaged portion, making it easy for the worker to perform the disengagement operation. As a result, for example, if it becomes necessary to change the position of the holder, this can be done easily, and the entire process of fixing the elongated body to the structure can be performed efficiently.

[0012] In one aspect, the holding device further includes a regulating portion that, when attached to the support device by sandwiching the elongated body, regulates the movement of the elongated body in the attachment / detachment direction in which the support device and the holding device are attached / detached, and each of the pair of engaging portions has multiple engaging pieces spaced apart in the attachment / detachment direction.

[0013] According to this configuration, by adjusting the position of the holder in the attachment / detachment direction and changing the engaging portion that engages with the engaged portion, the holder can hold a variety of elongated objects of different sizes. Therefore, in order to fix multiple types of elongated objects of different sizes to a structure, it is not necessary to prepare holders corresponding to elongated objects of each size, and the entire process of fixing the elongated objects to a structure can be performed efficiently.

[0014] In one embodiment, the restricting portion is configured as a plate-like body that is flexible and deformable along the outer shape of the elongated body.

[0015] According to this configuration, the restricting portion deforms along the outer shape of the elongated body to match the position of the holder relative to the support, allowing the holder to properly hold the elongated body. Therefore, the holder properly holds the elongated body regardless of the size of the elongated body being fixed, so there is no need to perform a separate operation to properly hold the elongated body, and the entire operation of fixing the elongated body to the structure can be performed efficiently.

[0017] 1. Overview of the elongated body fixing device according to the 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.

[0018] 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.

[0019] 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.

[0020] The holder 3 can be selected from a variety of types, each with a different distance between the pair of engaging portions 31. Specifically, holders 3 of different sizes are selected according to the size (e.g., outer diameter) of the elongated body 10. The size of the elongated body 10 that the holder 3 can hold 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 the holder 3 illustrated in FIG. 1 can hold 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 identify 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.

[0021] 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.

[0022] 2-1. Bass In this embodiment, the base 21 extends in one direction (longitudinal direction X) along the structure W. 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 the 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 positioned opposite 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 positioned on the opposite side of the structure W with respect to the fixing surface 213. In the following description, for ease of explanation, the term "longitudinal direction X" refers to the longitudinal direction X of the base 21, and the term "transverse direction Y" refers to the transverse direction Y of the base 21.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] In order for the holder 3 to deform into a shape that allows the engaging piece 311 to pass through the engaged hole 222, the engaging piece 311 illustrated in FIG. 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 toward the lower side Z2 in the height direction, as viewed from the short side 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 partially or completely restore, and the engaging piece 311 is positioned at the engaged position. As a result, the engaging piece 311 abuts against the engaged piece 221 from the upper side Z1 in the height direction, preventing the holder 3 from coming off the support 2.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] Preferably, the plate-like bodies 32 are 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 4. Method of using the elongated body fixing device of this 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.

[0066] 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.

[0067] 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 .

[0068] 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.

[0069] 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).

[0070] 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.

[0071] 5. Other embodiments (1) In the present 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.

[0072] (2) In the present 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.

[0073] (3) In the present 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. Furthermore, the fixed portion 23P may be fixed to the base 21 with an adhesive or the like.

[0074] (4) In the present embodiment, the intermediate portion 23C of the platform portion 231 in the fixed base 23 has been described as being plate-shaped 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.

[0075] (5) In the present 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.

[0076] (6) In the present embodiment, it has been described that the shape of the flexible portion 314 does not completely return to its original state when the engaging portion 31 engages with the engaged portion 22. However, the flexible portion 314 may be configured to completely return to its original state when the engaging portion 31 engages 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 engages with the engaged portion 22.

[0077] (7) In this embodiment, it has been described that there are 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.

[0078] 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 .

[0079] (8) In the present 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.

[0080] (9) In the present 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.

[0081] (10) In this embodiment, it has been described 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.

[0082] 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 .

[0083] (11) 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.
