Description

[Technical Field]

[0001] The present invention relates to a pipe fixing device and a pipe fixing structure for fixing a protective pipe for a cable or the like to an installation target such as a wall surface. [Background technology]

[0002] Conventionally, when laying pipes on the wall of a building, the pipes are fixed to the wall at predetermined intervals. A pipe fixing device is used to fix the pipes. The pipe fixing device has a holding part that holds the pipes and a fixing part that fixes the holding part to the wall.

[0003] As such a piping fixture, for example, a saddle having a substantially U-shaped holding portion and fixing portions formed on both sides of the holding portion has been proposed (Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2-107890 Summary of the Invention [Problem to be solved by the invention]

[0005] However, conventional pipe fixtures have an unsightly appearance because the fixing portion protrudes from the pipe when the pipe is held by the holding portion. In particular, the pipe fixtures must be installed in multiple locations at predetermined intervals, making them conspicuous.

[0006] Furthermore, since space is required to fasten the piping fixture, the piping can only be installed in locations where there is space available to install the piping fixture.

[0007] On the other hand, by limiting the fixing part to one place, the fixing part becomes less noticeable, but when the pipe is fixed, the force from the pipe may cause the pipe fixing device to rotate, causing the pipe to meander, which may result in a poor appearance. For this reason, a pipe fixing structure with a good appearance is desired.

[0008] The present invention has been made in view of the above problems, and has as its object to provide a piping fixture or the like that can provide a piping fixing structure that is aesthetically pleasing. [Means for solving the problem]

[0009] In order to achieve the above-mentioned object, the first invention is a piping fixture comprising a holding portion for holding a piping and a fixing portion for fixing the holding portion to an installation object, wherein the pair of fixing portions are arranged so as to protrude from the holding portions in the axial direction of the piping to be held, and when the piping is held in the holding portions, the piping can be held so that the fixing portions are hidden by the piping.

[0010] On the bottom surface of the piping fixing device, the vicinity of both ends in the width direction of the fixing portion and the holding portion perpendicular to the direction in which the pair of fixing portions are arranged may protrude toward the installation target compared to other portions.

[0011] The holding portion may be a clip having an opening in the center, and the opening may be opened by elastic deformation, allowing the pipe to be inserted into the holding portion.

[0012] The holding portion may be disposed offset upward with respect to an upper surface of the fixing portion.

[0013] A positioning mark may be formed on the outer surface of the holding portion substantially at the center in the axial direction of the pipe to be held, facing in the circumferential direction.

[0014] A positioning mark may be formed on the upper surface of the fixing portion at approximately the center of the width direction of the fixing portion, which is perpendicular to the axial direction of the pipe to be held, in the axial direction of the pipe to be held.

[0015] According to the first aspect of the present invention, the pair of fixing portions are arranged so as to protrude from the holding portion in the axial direction of the pipe to be held, so that when the pipe is held in the holding portion, the fixing portions can be hidden by the pipe. This results in a good aesthetic appearance. Furthermore, because the fixing portions do not protrude in the width direction of the pipe, they do not interfere with other structures, etc., and there is a high degree of freedom in the layout of the pipe.

[0016] Furthermore, by protruding the pair of fixing portions and the vicinity of both widthwise ends of the holding portion on the bottom surface of the piping fixture toward the installation target, it is possible to fix the other portions away from the installation target surface. Therefore, even if the installation target surface is slightly uneven, the impact can be suppressed. Furthermore, since the entire surface does not contact the installation target surface, the contact area can be reduced, and the surface pressure on the contact surface can be increased. In this way, by firmly pressing the vicinity of both ends of the holding portion perpendicular to the pair of fixing portions against the contact target surface, even when force is applied to the piping fixture, it is possible to suppress misalignment and deformation, and to more stably fix the piping fixture to the installation target surface.

[0017] Furthermore, by making the shape of the holding part a clip with an opening in the center, the opening can be opened by elastic deformation of the holding part, making it possible to easily insert the pipe into the holding part, which improves the workability of laying the pipe.

[0018] Furthermore, by offsetting the holding part upward from the upper surface of the fixing part, interference between the fitting and the installation surface can be prevented even when a fitting or the like is connected to the piping. Furthermore, when a fixing member such as a screw is used for the fixing part, interference between the fixing member and the piping can be suppressed.

[0019] In addition, by forming a positioning mark in the circumferential direction on the outer surface of the holding part at the axial center of the pipe to be held, the axial installation position and orientation of the pipe fixing device can be aligned with a marking line, etc.

[0020] Similarly, by forming a positioning mark on the upper surface of the holding part, approximately in the center of the width of the holding part, in the axial direction of the piping to be held, the installation position and orientation of the piping fixing device in the width direction can be aligned with the marking line, etc.

[0021] A second invention is a structure for fixing piping to an installation target, comprising a piping fixture fixed to the installation target, and piping held by the piping fixture, wherein the piping fixture has a holding portion and a fixing portion, the piping is held by the holding portion, the fixing portions are arranged so as to protrude from the holding portion in the axial direction of the piping, the piping fixture is fixed to the installation target by a pair of the fixing portions, and the fixing portions are hidden by the piping and cannot be seen from the front.

[0022] According to the second aspect of the present invention, when the piping is held by the holding portion, the fixing portion can be hidden by the piping, resulting in a good aesthetic appearance. [Effects of the Invention]

[0023] According to the present invention, it is possible to provide a pipe fixing device or the like that can provide a pipe fixing structure with excellent aesthetics. [Brief explanation of the drawings]

[Figure 6] 1A is a diagram showing a process of attaching a pipe 21 to a pipe fixture 1, and FIG. 1B is a diagram showing a pipe fixing structure 20 in which a pipe 21 is attached to the pipe fixture 1. FIG. [Figure 7] FIG. 2 is a front view showing the piping fixing structure 20. [Figure 8] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0025] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1(a) is an upper perspective view showing a piping fixture 1, and Fig. 1(b) is a lower perspective view showing the piping fixture 1. Fig. 2(a) is a plan view of the piping fixture 1, Fig. 2(b) is a side view of the piping fixture 1, and Fig. 3 is a front view of the piping fixture 1. The piping fixture 1 is integrally formed from, for example, resin, and is composed of a holding portion 3, a fixing portion 5, etc.

[0026] The holding part 3 is a part that holds the pipe, and is shaped like a clip having an opening 7 in the center at the top and a pair of holding arms 4 arranged opposite each other. When inserting a pipe with a diameter larger than the opening width of the opening 7 from above, the opening 7 is pushed open by the elastic deformation of the holding arms 4, and the pipe can be inserted into the holding part 3. When the pipe is inserted into the holding part 3, the elastic deformation of the holding arms 4 is restored to the original width of the opening 7, and the pipe is held by the holding part 3.

[0027] The inner surface of the holding portion 3 (holding arm 4) has an arc shape corresponding to the outer shape of the circular pipe. Furthermore, a pipe fitting protrusion 9 that protrudes inward is provided on the arc-shaped portion of the holding portion 3. The pipe fitting protrusion 9 is formed to a predetermined length along the arc shape. As will be described in detail later, when a corrugated pipe in which large diameter portions and small diameter portions are repeatedly formed in the longitudinal direction is placed in the holding portion 3, the pipe fitting protrusion 9 fits into the small diameter portion, thereby suppressing axial displacement of the pipe. Note that the holding portion 3 may have a form other than the holding arm 4 as long as it is capable of holding the pipe.

[0028] The fixing portion 5 is a portion for fixing the holding portion 3 to an installation target. The fixing portion 5 is formed with a hole 11 for inserting a fixing member such as a screw.

[0029] 2(a) and 2(b), the axial direction of the pipe held by the holding part 3 is defined as the X direction. That is, when the pipe is fixed as described above, the opening 7 is pushed open and elastically deformed in the Y direction (FIGS. 2(a) and 3) perpendicular to the axial direction X of the held pipe.

[0030] 2(a), the pair of fixing portions 5 are arranged so as to protrude in the axial direction X of the pipe being held relative to the holding portion 3. That is, in a plan view, the pair of holding arms 4 of the holding portion 3 that hold the pipe and the pair of fixing portions 5 are arranged so as to be perpendicular to each other.

[0031] The width of the fixed part 5 (width in the Y direction) is sufficiently smaller than the inner surface width of the holding part 3 (the distance between the inner surfaces of the opposing holding arms 4). Furthermore, the hole 11 formed in the fixed part 5 is elongated in the width direction (Y direction) of the fixed part 5 to facilitate position adjustment.

[0032] 3, in the height direction Z, the lower end position H2 of the holding part 3 is offset upward with respect to the height position H1 of the upper surface of the fixing part 5. In other words, the piping held by the holding part 3 is positioned at least above the lower end of the holding part 3 (the upper surface of the bottom of the holding part 3), so that the piping can be held at a position higher than the upper surface of the fixing part 5.

[0033] On the bottom side of the piping fixture 1 (see FIG. 1(b)), protrusions 15a and 15b are formed near the tip of the fixing portion 5 and near both ends of the holding portion 3 in the width direction perpendicular to the direction in which the pair of fixing portions are arranged. Protrusions 15a and 15b are portions that protrude downward (toward the installation target) compared to other portions on the bottom surface. In other words, when the piping fixture 1 is installed on the installation target surface, gaps are formed between the installation target surface and the portions other than protrusions 15a and 15b.

[0034] 2(b), a groove 13a is formed in the outer peripheral surface of the holding portion 3 in the outer circumferential direction. The groove 13a is formed linearly in the approximate center (center in the X direction) of the holding portion 3. The groove 13a functions as a mark for indicating the positioning and orientation of the piping fixture 1 in the X direction.

[0035] Similarly, groove 13b is formed on the top surface of fixing part 5 in the axial direction X of the pipe. Groove 13b is formed linearly at approximately the center of the width direction (Y direction) of fixing part 5. Groove 13b functions as a mark for indicating the positioning and orientation of piping fixture 1 in the Y direction.

[0036] Next, a method of using the piping fixture 1 will be described. Fig. 4(a) is a front view showing the state in which the piping fixture 1 has been fixed to a wall surface 19, which is the installation surface, and Fig. 4(b) is a side view of the wall surface 19. As described above, the piping fixture 1 is fixed to the wall surface 19 by inserting fixing members 17 such as screws into the holes 11 of the pair of fixing parts 5. At this time, since the holding arms 4 of the holding parts 3 and the like are not above the holes 11, the work of screwing in the fixing members 17 with a tool is easy.

[0037] Furthermore, for example, when a marking line A (position in a direction perpendicular to the laying direction of the pipe) and a marking line B (position of the laying axis of the pipe) are provided on the wall surface 19, the grooves 13a and 13b described above are arranged to align with the marking lines A and B. In this way, the pipe fixing device 1 can be fixed to the wall surface 19 in the correct position and orientation.

[0038] 5 is a conceptual diagram showing the contact portions between wall surface 19 and piping fixture 1 when piping fixture 1 is fixed to wall surface 19. As described above, only protrusion 15a on the bottom side of fixing portion 5 and portions corresponding to protrusions 15b near both ends in the width direction of holding portion 3 come into contact with wall surface 19, and other portions do not come into contact with wall surface 19.

[0039] In this way, by preventing the entire bottom surface of piping fixture 1 from contacting wall surface 19, it is possible to install piping fixture 1 while avoiding slight irregularities in wall surface 19. Furthermore, compared to when the entire bottom surface of piping fixture 1 is in contact, the contact area with wall surface 19 can be made smaller, allowing for greater surface pressure.

[0040] In particular, since the pair of fixing parts 5 are arranged at positions spaced apart with the holding part 3 therebetween, it is possible to position the contact parts of the pair of protrusions 15a with the wall surface 19 at separate positions. Furthermore, since the protrusions 15b are arranged at separate positions near the ends in the direction perpendicular to the pair of fixing parts 5, it is possible to position the contact parts of the pair of protrusions 15b with the wall surface 19 at separate positions.

[0041] In this way, by positioning the contact portions of the piping fixture 1 with the wall surface 19 at positions spaced apart from each other in four directions, the piping fixture 1 and the wall surface 19 are brought into close contact with each other, and misalignment and tilting of the piping fixture 1 can be efficiently suppressed.

[0042] Next, as shown in FIG. 6(a), the pipe 21 is inserted through the opening 7. FIG. 6(b) is a diagram showing the pipe fixing structure 20 in which the pipe 21 is held by the pipe fixing device 1 and fixed to the wall surface 19. As described above, the outer diameter of the pipe 21 is larger than the width of the opening 7 of the holding part 3, so that the holding arm 4 can be elastically deformed to insert the pipe 21 into the holding part 3 and hold the pipe 21 by the holding part 3. In other words, the pipe 21 is fixed to the pipe fixing device 1.

[0043] 7 is a front view of pipe fixing structure 20. As described above, fixing portion 5 is formed in the axial direction of pipe 21 and has a width narrower than the outer diameter of pipe 21, so that when pipe 21 is held by holding portion 3, pipe 21 can be held so that fixing portion 5 is hidden by pipe 21. In other words, pipe fixing structure 20 cannot be seen from the front because fixing portion 5 is hidden by pipe 21.

[0044] Here, if the width of the opening 7 of the piping fixture 1 is narrowed, it becomes difficult to insert the piping 21, and the holding portion 3 becomes noticeable when the piping fixing structure 20 is viewed from the front. On the other hand, if the opening 7 is widened, the holding force of the piping 21 is weakened. For this reason, as shown in FIG. 6(b), when the outer diameter of the piping 21 is D (the outer diameter D of the piping 21 roughly coincides with the maximum distance between the arc-shaped portions of the pair of holding arms 4), it is desirable that the width C of the opening 7 (the distance between the pair of holding arms 4 at the opening 7) be approximately 75 to 95% of the piping diameter D.

[0045] As described above, the lower end of the holding portion 3 is located above the upper surface of the fixing portion 5. That is, the height F to the lower end of the pipe 21 is greater than the thickness E of the fixing portion 5. Therefore, in the pipe fixing structure 20, a gap (FE) is formed between the lower end of the pipe 21 and the upper surface of the fixing portion 5. Therefore, the fixing member 17 does not interfere with the pipe 21. Furthermore, the pipe 21 can be fixed at a distance F from the wall surface 19.

[0046] 8 is a diagram showing a state in which fitting 23 is connected to a portion of pipe 21. The outer diameter of fitting 23 is larger than the outer diameter of pipe 21. However, with pipe fixing device 1, pipe 21 can be positioned a predetermined distance (F in FIG. 6(b)) away from wall surface 19. This makes it possible to prevent fitting 23 from interfering with wall surface 19. This allows pipe 21 to be fixed to wall surface 19 in a straight line without meandering.

[0047] As described above, according to this embodiment, most of the piping fixture 1, and especially the fixing portion 5, is hidden by the piping 21, resulting in a good aesthetic appearance. Furthermore, because the piping 21 can be fixed away from the wall surface 19, even when the fitting 23 and the like are connected, the piping 21 can be arranged straight, including the fitting 23. This makes it possible to prevent the piping 21 from becoming wavy, or otherwise deteriorating the appearance.

[0048] Furthermore, by arranging the fixing portions 5 in two locations spaced apart from each other, it is possible to suppress rotation of the piping fixture 1. For example, if the pipe 21 is bent and placed on the wall surface 19, the pipe fixture 1 may be subjected to the restoring force of the pipe 21 and rotate (shift in orientation), but by fixing the pipe fixture 1 to the wall surface 19 at two locations spaced apart from each other, rotation of the pipe fixture 1 is suppressed and the orientation of the pipe 21 can be accurately maintained. In this case, even if the spacing between the pair of fixing portions 5 is wide, it is hidden by the pipe 21 and does not spoil the appearance.

[0049] Furthermore, because the fixing portion 5 does not protrude on either side of the piping fixture 1 (in the direction perpendicular to the axial direction of the piping 21), the piping fixtures 1 can be placed close to each other. Therefore, for example, even when adding a new pipe next to an existing pipe, the new pipe can be placed close to the existing pipe. Furthermore, because the piping fixture 1 can be installed in the corner of a wall surface 19, there are fewer restrictions on where it can be installed.

[0050] Furthermore, since the undersides of fixing part 5 and holding part 3 come into contact with wall surface 19 at four spaced apart locations, installation is easy even if part of the surface of wall surface 19 is uneven. Furthermore, because the contact area can be reduced, the surface pressure increases, making it possible to suppress displacement of piping fixture 1 due to the force from piping 21 described above.

[0051] Furthermore, by providing grooves 13a and 13b in visible locations when installing piping fixture 1, it is easy to align the installation position and orientation of piping fixture 1. This makes installation of piping fixture 1 easy.

[0052] Although the embodiments of the present invention have been described above with reference to the accompanying drawings, the technical scope of the present invention is not limited to the above-described embodiments. It is clear that those skilled in the art can conceive of various modifications and alterations within the scope of the technical ideas described in the claims, and it is understood that these modifications and alterations also fall within the technical scope of the present invention.
