Description

[Technical field]

[0001] The present invention relates to a saddle base and a pipe holding member used to hold a pipe. [Background technology]

[0002] There is a bracket (pipe holding member) for holding multiple pipes that run parallel to the intersection (intersection) of a ceiling and a wall (see, for example, Patent Document 1). The saddle base of the bracket in Patent Document 1 is provided with a fixing plate fixed to the ceiling and a fixing plate fixed to the wall. A saddle for holding the pipes is attached to each of the two fixing plates, and the multiple pipes can be held by the saddles. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2022-172820 Summary of the Invention [Problem to be solved by the invention]

[0004] In some cases, a larger diameter pipe is installed in the room where the ceiling and the wall intersect. In order to hold the larger diameter pipe, a larger saddle is also required. In the saddle base of the bracket in Patent Document 1, even if the bracket is made larger while preventing the bracket from becoming larger in the direction from the room's entrance toward the inside of the room, that is, preventing the bracket from becoming larger in the direction perpendicular to the axis of the pipe, the saddle attached to the ceiling side and the saddle attached to the wall side interfere with each other, making it impossible to achieve a configuration that can hold the larger diameter pipe.

[0005] An object of the present invention is to provide a saddle base and a pipe holding member that are capable of holding large diameter pipes while suppressing an increase in size of the pipe holding member in a direction perpendicular to the axial direction of the pipe. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the saddle base of the invention of claim 1 is a saddle base that is attached to an inlet where a first construction surface and a second construction surface intersect, and to which a plurality of saddles are attached for holding a plurality of parallel pipes, and comprises a first base portion that extends along the first construction surface and has a first saddle mounting portion on the opposite side to the first construction surface, and a second base portion that extends along the second construction surface and has a second saddle mounting portion on the opposite side to the second construction surface, and the first base portion and the second base portion are arranged so as to be offset from each other in the axial direction of the pipes.

[0007] The invention of claim 2 is based on claim 1 and further includes a connecting portion that connects the first base portion and the second base portion, the first base portion, the second base portion and the connecting portion being arranged so as to be offset from each other in the axial direction of the piping, and a cable tie passage is formed in the connecting portion through which a cable tie for holding a third piping can be inserted.

[0008] The invention of claim 3 is based on claim 2, and further comprises an intermediate hole formed in the cable tie passage between two insertion openings through which the cable tie can be inserted.

[0009] The pipe retaining member of the invention of claim 4 is a pipe retaining member that is attached to an intersection where a first construction surface and a second construction surface intersect, and is for retaining multiple parallel pipes, and comprises a first saddle portion that is arranged on the first construction surface and for retaining a first pipe, and a second saddle portion that is arranged on the second construction surface and for retaining a second pipe, and the first saddle portion and the second saddle portion are arranged so as to be offset from each other in the axial direction of the pipes.

[0011] [One embodiment] An embodiment embodied in a saddle base of a bracket used in a piping cover system will be described below.

[0012] As shown in Fig. 1, a horizontally extending plate-shaped molding 94 is disposed at an entrance 93 where a ceiling 91 as a first construction surface and a wall 92 as a second construction surface intersect. A plurality of pipes, i.e., a first pipe 95, a second pipe 96, and a third pipe 97, are attached to the entrance 93 and run in parallel. The first to third pipes 95 to 97 extend in the same direction as the entrance 93 and the molding 94.

[0013] The first pipe 95 is, for example, a pipe for supplying cold water, the second pipe 96 is, for example, a pipe for supplying hot water, and the third pipe 97 is, for example, a pipe for reheating water for bathing. The first and second pipes 95, 96 are large in diameter to increase the flow rate. In the drawings, the axial direction L represents the axial direction of the first to third pipes 95-97.

[0014] 1 and 2, the pipe cover system 1 includes a pipe cover 2 and a bracket 10. In FIG. 1, the pipe cover 2 and first to third pipes 95 to 97 are shown partially cut away to make the configuration of each part easier to see.

[0015] The pipe cover 2 is for covering the first to third pipes 95 to 97, is made of resin, and has an L-shaped cross section with the space between the inlet 93 as the pipe housing portion 3. The first to third pipes 95 to 97 are housed in the pipe housing portion 3 of the pipe cover 2. The pipe cover 2 includes a flange portion 4, a first fitting claw 5, and a second fitting claw 6. The first fitting claw 5 and the second fitting claw 6 function as an engagement portion for engaging the pipe cover 2 with the bracket 10. The flange portion 4 protrudes from the edge of the pipe cover 2 toward the outside of the pipe cover 2 and extends along the longitudinal direction of the pipe cover 2. The flange portion 4 is used when fixing the pipe cover 2 to the ceiling 91 and the wall 92, and there are a type that is fixed to the ceiling 91 and a type that is fixed to the wall 92.

[0016] The first fitting claw 5 and the second fitting claw 6 are formed near the flange 4 fixed to the ceiling 91, and are also formed near the flange 4 fixed to the wall 92. The first fitting claw 5 and the second fitting claw 6 protrude into the piping accommodating portion 3 and extend in the longitudinal direction of the piping cover 2 so as to be parallel to each other.

[0017] Next, the bracket 10 will be described. Bracket 10 is made of resin and is fixed directly to at least one of ceiling 91 and wall 92. Bracket 10 in this example is fixed directly to both ceiling 91 and wall 92. Bracket 10 functions as a pipe holding member that holds a plurality of pipes such as first to third pipes 95 to 97. As shown in FIG. 2, bracket 10 is located in correspondence with pipe cover 2, and is housed in pipe housing portion 3 formed by pipe cover 2. Bracket 10 holds first to third pipes 95 to 97.

[0018] As shown in FIGS. 1 and 2, the bracket 10 includes a saddle base 20, a first saddle 60, and a second saddle 70. The saddle base 20 can be fixed to both a ceiling 91 and a wall 92. The saddle base 20 includes a first base portion 21 fixed to the ceiling 91, a second base portion 22 fixed to the wall 92, and a connecting portion 23. The connecting portion 23 connects the first base portion 21 and the second base portion 22 together.

[0019] 2, the first base portion 21 is spaced a predetermined distance from the wall 92, and the second base portion 22 is spaced a predetermined distance from the ceiling 91. This prevents the saddle base 20 fixed to the ceiling 91 and the wall 92 from coming into contact with the molding 94. In this embodiment, the distance by which the first base portion 21 is spaced from the wall 92 and the distance by which the second base portion 22 is spaced from the ceiling 91 are equal to each other.

[0020] Next, the first base portion 21 will be described in detail. 2 and 3, the first base portion 21 extends along the ceiling 91 and has a first saddle mounting portion 24 on the opposite side to the ceiling 91. The first saddle mounting portion 24 is formed in a flat plate shape extending parallel to the ceiling 91.

[0021] 3, in the first saddle attachment portion 24, at the end portion opposite the wall 92 side, a small end wall 25 is formed standing in a direction away from the ceiling 91. The position where the end wall 25 is provided is also the end portion of the first base portion 21 opposite the wall 92 side. At the tip of the end wall 25, a first claw 26 is formed that protrudes toward the wall 92 side.

[0022] In the first saddle mounting portion 24, a small mounting piece 27 is formed in a position close to the wall 92 side, and is erected in a direction away from the ceiling 91. A second claw 28 is formed at the tip of the mounting piece 27, protruding toward the opposite side to the wall 92. The two claws 26, 28 are for mounting the first saddle 60 to the saddle base 20 (first saddle mounting portion 24), and function as an engagement portion. Between the two claws 26, 28 in the first saddle mounting portion 24, a positioning protrusion 29 is formed, protruding in a direction away from the ceiling 91. The distance between the positioning protrusion 29 and one of the two claws 26, 28 is shorter than the distance between the positioning protrusion 29 and the other. The positioning protrusion 29 is for positioning the first saddle 60 with respect to the first saddle mounting portion 24 when the first saddle 60 is mounted to the first saddle mounting portion 24 by the two claws 26, 28.

[0023] The first saddle mounting portion 24 has a screw hole 30 formed therein. The first base portion 21 (saddle base 20) is fixed to the ceiling 91 by driving a screw into the ceiling 91 through this screw hole 30. As shown in Fig. 4, the first saddle mounting portion 24 has three holes 31 formed therein in addition to the screw hole 30. These three holes 31 are formed in association with the positioning protrusion 29 and the two claws 26, 28 when the saddle base 20 is manufactured by injection molding.

[0024] 3, the first base portion 21 has a reinforcing wall 32. The reinforcing wall 32 protrudes in a direction away from the ceiling 91 so as to surround the first saddle attachment portion 24 from three directions. The reinforcing wall 32 has a front wall portion 33, a rear wall portion 34, and a side wall portion 35.

[0025] The front wall 33 is located at the end of the first base 21 opposite to the wall 92 side, and is formed continuously from the tip of the end wall 25 of the first saddle mounting portion 24. A step 36 is formed in the front wall 33. A tip 37 in the protruding direction of the front wall 33 and the step 36 are used when engaging the piping cover 2 with the bracket 10. That is, the front wall 33 including the step 36 and the tip 37 is disposed on the ceiling 91 and functions as a first engaging portion for engaging with the piping cover 2. From the viewpoint of engaging with the piping cover 2, the saddle base 20 also functions as a cover base to which the piping cover 2 is attached. The back wall 34 is located at the end of the first base 21 opposite to the front wall 33, that is, the end on the wall 92 side. The side wall 35 extends in a direction perpendicular to the axial direction L so as to connect the front wall 33 and the back wall 34. The side wall portion 35 is formed with an arc-shaped cutout 35a.

[0026] The second base portion 22 extends along the wall 92 and has a second saddle mounting portion 38 on the opposite side to the wall 92. The first base portion 21 and the second base portion 22 have a structure that is rotationally symmetrical with each other about an axis P that passes through the center of the connecting portion 23 and is perpendicular to the connecting portion 23. That is, the second base portion 22 has the same configuration as the first base portion 21 except that the positional relationship in the first base portion 21 is replaced by the wall 92 from the ceiling 91, such as the second base portion 22 being fixed to the wall 92, the second saddle mounting portion 38 extending parallel to the wall 92, the end wall 25 protruding in a direction away from the wall 92, and the reinforcing wall 32 protruding in a direction away from the wall 92. Therefore, a detailed description of the second base portion 22 will be omitted. The front wall portion 33 having the step portion 36 and the tip portion 37 of the second base portion 22 is disposed on the wall 92 and functions as a second engagement portion for engaging with the piping cover 2. In the drawings, in the second base portion 22, the same structures as those in the first base portion 21 are denoted by the same reference numerals.

[0027] Next, the connecting portion 23 will be described. 3, the first base portion 21, the second base portion 22, and the connecting portion 23 are arranged so as to be mutually offset in the axial direction L. In detail, the connecting portion 23 is formed between the first base portion 21 and the second base portion 22, and is inclined at an angle of 45 degrees with respect to the ceiling 91 and the wall 92 as a whole, forming an elongated flat plate shape. The connecting portion 23 is formed with a cable tie passage 40 through which a cable tie 39 for holding the third piping can be inserted, and a first reinforcing piece 41 and a second reinforcing piece 42 protruding from the cable tie passage 40.

[0028] The cable tie passage 40 is disposed between the first base portion 21 and the second base portion 22 in the axial direction L, and extends in a direction intersecting the axial direction L. The cable tie passage 40 extends linearly from the ceiling 91 to the wall 92, and has a guide plate 43 capable of guiding the cable tie 39. In the guide plate 43, a portion on the ceiling 91 side (first base portion 21 side) forms a first guide portion 44, and a portion on the wall 92 side (second base portion 22 side) forms a second guide portion 45. In the cable tie passage 40, an insertion portion 46 is formed between the first guide portion 44 and the second guide portion 45.

[0029] At each of both ends of the insertion portion 46, an insertion hole 47 through which the cable tie 39 can be inserted is formed. One of the two insertion holes 47 is disposed on the ceiling 91 side (the first base portion 21 side), and the other of the two insertion holes 47 is disposed on the wall 92 side (the second base portion 22 side). Between the two insertion holes 47, an intermediate hole 48 through which the cable tie 39 can be inserted is formed. In the guide plate 43, a portion corresponding to the intermediate hole 48 forms a third guide portion 49. In the insertion portion 46, a side wall 50 is erected adjacent to the third guide portion 49. A hole 51 is formed in the side wall 50. This hole 51 is formed together with the insertion portion 46 when the saddle base 20 is manufactured by injection molding. The first guide portion 44 guides the cable tie 39 to the insertion opening 47 when the cable tie 39 is inserted from the insertion opening 47 on the ceiling 91 side, the second guide portion 45 guides the cable tie 39 to the insertion opening 47 when the cable tie 39 is inserted from the insertion opening 47 on the wall 92 side, and the third guide portion 49 guides the cable tie 39 to the insertion opening 47 when the cable tie 39 is inserted from the intermediate hole 48. In the bracket 10, the third piping 97 can be held by the cable tie 39 inserted through the cable tie passage 40.

[0030] The first reinforcement piece 41 of the connecting portion 23 is connected to the first base portion 21, and the second reinforcement piece 42 is connected to the second base portion, and these reinforcement pieces 41, 42 increase the connection strength between the first base portion 21, the second base portion 22, and the connecting portion 23.

[0031] Next, a description will be given of the first saddle 60. The first saddle 60 is disposed on the ceiling 91 side of the saddle base 20 and attached to the first saddle attachment portion 24, and serves to hold the first pipe 95. As shown in FIG. 4, the first saddle 60 includes a main body 61 and an opening / closing portion 62. The main body 61 has an arc-shaped concave surface 63 for receiving a pipe (the first pipe 95 in this example). The arc shape of this concave surface 63 corresponds to the arc shape of the notch 35a of the side wall portion 35 of the first base portion 21. The opening / closing portion 62 is formed in an arc shape, and one end of the opening / closing portion 62 is connected to a portion of the main body 61 that corresponds to one end of the concave surface 63. The opening / closing portion 62 can open and close with respect to the concave surface 63 of the main body 61, centering on the portion that corresponds to one end of the concave surface 63 of the main body 61.

[0032] A locking claw 64 is formed on the end of the opening / closing part 62 opposite to the end connected to the main body 61. When the opening / closing part 62 is closed relative to the concave curved surface 63 of the main body 61, the locking claw 64 of the opening / closing part 62 becomes hooked on a locked part 65 formed on the main body 61. The locked part 65 has many ridges. These ridges allow the locking claw 64 to be displaced when the opening / closing part 62 is closed. On the other hand, the locking claw 64 is prevented from being displaced when the opening / closing part 62 is opened by being hooked on the ridges.

[0033] Two claw receiving portions 66 are formed at a distance from each other on the side of the main body 61 opposite the concave curved surface 63. The two claw receiving portions 66 are for attaching the main body 61 to the first base portion 21. A screw hole 67 is formed between the two claw receiving portions 66 on the main body 61, and a positioning recess 68 is formed around the screw hole 67. The distance between the positioning recess 68 and one of the two claw receiving portions 66 is shorter than the distance between the positioning recess 68 and the other.

[0034] The second saddle 70 is disposed on the wall 92 side of the saddle base 20, attached to the second saddle attachment portion 38, and serves to hold the second pipe 96. The second saddle 70 has the same structure as the first saddle 60, and therefore a detailed description thereof will be omitted. In this embodiment, the two saddles 60, 70 are large so as to be able to hold the first and second pipes 95, 96, which have large diameters.

[0035] Next, the attachment of the first saddle 60 to the saddle base 20 will be described. The first saddle 60 is attached to the first base portion 21 (first saddle attachment portion 24) using two claws 26, 28, and similarly the second saddle 70 is attached to the second base portion 22 (second saddle attachment portion 38) using two claws 26, 28. Here, the first saddle 60 and the first base portion 21 constitute the first saddle portion, and the second saddle 70 and the second base portion 22 constitute the second saddle portion. The following mainly describes the attachment of the first saddle 60 to the first base portion 21.

[0036] As shown in FIG. 4, the two claw receiving portions 66 of the main body 61 of the first saddle 60 are opposed to the two claws 26, 28 of the first base portion 21. In this state, when the main body 61 is brought close to the first base portion 21, the main body 61 is sandwiched between the two claws 26, 28, and the positioning protrusion 29 of the first base portion 21 is inserted into the positioning recess 68 of the main body 61. By sandwiching the main body 61 between the two claws 26, 28 of the first base portion 21, the two claws 26, 28 are caught by the two claw receiving portions 66 of the main body 61. As a result, the main body 61 is attached to the first base portion 21 and is prevented from being separated from the first base portion 21. At this time, the screw hole 67 of the main body 61 is positioned on the same axis as the screw hole 30 of the first base portion 21. In addition, the main body 61 of the first saddle 60 is in contact with the end wall 25 of the first base portion 21. That is, the first saddle 60 is disposed at a position on the first base portion 21 (at the first saddle attachment portion 24) that is farthest from the wall 92 and the second base portion 22.

[0037] The positioning protrusion 29 and the positioning recess 68 are provided to prevent the main body 61 from being attached to the first base part 21 in a state in which the main body 61 is rotated 180° so that the positions of the two claw receiving parts 66 are interchanged. That is, in this case, the positioning protrusion 29 and the positioning recess 68 are misaligned, so that when the main body 61 is brought close to the first base part 21, the positioning protrusion 29 cannot be inserted into the positioning recess 68. As a result, the main body 61 cannot be inserted between the two claws 26, 28, and the main body 61 cannot be attached to the first base part 21. The positioning protrusion 29 and the positioning recess 68 make it possible to keep the opening and closing direction of the opening and closing part 62 constant when the main body 61 is attached to the first base part 21. The method of attaching the second saddle 70 to the second base portion 22 is the same as the method of attaching the first saddle 60 to the first base portion 21.

[0038] Next, we will explain the positional relationship between the first base portion 21 and the second base portion 22, the positional relationship between the first saddle 60 and the second saddle 70, the positional relationship between the first saddle portion and the second saddle portion, and the positional relationship between the first engagement portion (front wall portion 33 of the first base portion 21) and the second engagement portion (front wall portion 33 of the second base portion 22).

[0039] As shown in FIG. 1 and FIG. 4, in the saddle base 20, the first base portion 21 and the second base portion 22 are arranged so as to be mutually offset in the axial direction L, and do not overlap with each other in the axial direction L. More specifically, the first base portion 21 and the second base portion 22 are spaced apart from each other in the axial direction L by the width of the guide plate 43 of the connecting portion 23. Therefore, the first saddle 60 attached to the first saddle mounting portion 24 and the second saddle 70 attached to the second saddle mounting portion 38 are arranged so as to be mutually offset in the axial direction L, and do not overlap with each other. That is, the first saddle portion constituted by the first base portion 21 and the first saddle 60 and the second saddle portion constituted by the second base portion 22 and the second saddle 70 are arranged so as to be mutually offset in the axial direction L. Further, the first engagement portion, which is the front wall portion 33 of the first base portion 21, and the second engagement portion, which is the front wall portion 33 of the second base portion 22, are disposed so as to be shifted from each other in the axial direction L.

[0040] 2, the first base portion 21 and the second base portion 22 are arranged so as to be offset from each other and not overlap each other on a plane perpendicular to the axial direction L. On the other hand, the first saddle 60 and the second saddle 70 are arranged so as to partially overlap each other on a plane perpendicular to the axial direction L.

[0041] Next, an example of how the bracket 10 holds the pipes will be described in detail. 2, in the bracket 10, the first pipe 95 is held by the first saddle 60, the second pipe 96 by the second saddle 70, and the third pipe 97 by the cable tie 39. In detail, in the first saddle 60, the opening / closing part 62 is closed with the first pipe 95 sandwiched between the main body 61 and the opening / closing part 62, and the locking claw 64 of the opening / closing part 62 is hooked onto the locked part 65 of the main body 61, thereby holding the first pipe 95 between the main body 61 and the opening / closing part 62. In a similar state, the second pipe 96 is held by the second saddle 70.

[0042] The cable tie 39 is inserted through the cable tie passage 40 (specifically, the two insertion holes 47) so as to pass between the ceiling 91 and the first pipe 95 and between the wall 92 and the second pipe 96. The cable tie 39 binds the third pipe 97 together with the first and second pipes 95, 96, and holds the third pipe 97.

[0043] 2, as shown in Fig. 5, the cable tie 39 can be inserted into the cable tie passage 40 (specifically, the intermediate hole 48 and the insertion opening 47 on the second base portion 22 side) so as to pass between the first pipe 95 and the second pipe 96 and between the wall 92 and the second pipe 96. In this state, the cable tie 39 binds the second pipe 96 and the third pipe 97 together, and holds the third pipe 97.

[0044] Next, a procedure for installing the pipe cover system 1 will be described. The saddle base 20 of the bracket 10 is fixed by screws to a portion of the recess 93 where the piping cover 2 is to be disposed. The fixing of the saddle base 20 at this time may be performed without attaching the saddles 60, 70 to the saddle base 20, or may be performed by attaching at least one of the two saddles 60, 70 to the saddle base 20. When the above fixing is performed with the two saddles 60, 70 attached to the saddle base 20, screws are driven into the ceiling 91 or wall 92 through the screw holes 67 of the saddles 60, 70 and the screw holes 30 of the saddle base 20.

[0045] Thereafter, the first to third pipes 95 to 97 are held in the socket 93 using the bracket 10. Specifically, the first and second pipes 95, 96 are held by the two saddles 60, 70, and then the third pipe 97 is held using a cable tie 39.

[0046] Here, when the third pipe 97 is held in the state shown in FIG. 2, the cable tie 39 is inserted between the first saddle 60 and the second saddle 70 (i.e., between the first base portion 21 and the second base portion 22) in the axial direction L, and between the ceiling 91 and the first pipe 95 in the direction perpendicular to the axial direction L. Then, the cable tie 39 is guided by the guide plate 43 (specifically, the first guide portion 44) to the insertion opening 47 on the first guide portion 44 side and inserted. At this time, in the axial direction L, the cable tie 39 is guided by the side wall portion 35 of the first base portion 21 adjacent to the first guide portion 44. When the cable tie 39 is further pushed forward, it is also inserted into the insertion opening 47 on the second guide portion 45 side. The third pipe 97 can be held using the cable tie 39 inserted into the cable tie passage 40 in this manner.

[0047] Alternatively, when the third pipe 97 is held in the state shown in FIG. 5, the cable tie 39 is inserted between the first saddle 60 and the second saddle 70 in the axial direction L and between the first pipe 95 and the second pipe 96 in the direction perpendicular to the axial direction L. Then, the cable tie 39 that has passed through the intermediate hole 48 is guided by the guide plate 43 (specifically, the third guide portion 49) to the insertion opening 47 on the second guide portion 45 side and inserted. At this time, in the axial direction L, the cable tie 39 is guided by the side wall 50 adjacent to the third guide portion 49 and the side wall portion 35 of the second base portion 22 adjacent to the second guide portion 45. The third pipe 97 can be held using the cable tie 39 inserted through the cable tie passage 40 in this manner.

[0048] After the first to third pipes 95-97 are held in the recess 93 by the bracket 10, the pipe cover 2 is engaged with the bracket 10. More specifically, the bracket 10 and the first to third pipes 95-97 are covered with the pipe cover 2, and the first fitting claws 5 and the second fitting claws 6 of the pipe cover 2 are positioned corresponding to the front wall portion 33 of the bracket 10 and pressed in, whereby the first fitting claws 5 and the second fitting claws 6 of the pipe cover 2 sandwich the step portion 36 and the tip portion 37 of the front wall portion 33 of the bracket 10. This engages the pipe cover 2 with the bracket 10.

[0049] When the piping cover 2 is engaged with the bracket 10, the first to third pipes 95-97 are accommodated in the pipe accommodating portion 3 between the piping cover 2 and the ceiling 91 and wall 92, and are shielded by the piping cover 2. Thereafter, the piping cover 2 is fixed to the ceiling 91 and the wall 92 with screws.

[0050] Next, the effects of the bracket 10 of this embodiment will be described. (1) In the saddle base 20, the first base portion 21 and the second base portion 22 are disposed so as to be shifted from each other in the axial direction L. If, unlike this embodiment, the first base portion 21 and the second base portion 22 were configured to be disposed at the same position in the axial direction L, then in order to maintain the size of the bracket 10 in a direction perpendicular to the axial direction L, the two large saddles 60, 70 attached to the two base portions 21, 22 would interfere with each other, making it impossible to provide two saddles 60, 70. In order to provide two saddles 60, 70, it would be necessary to position at least one of them farther away from the ceiling 91 or wall 92, which would result in the bracket 10 becoming larger in the direction perpendicular to the axial direction L and protruding further from the recess 93 toward the inside of the room.

[0051] However, in the bracket 10 of this embodiment, the first base portion 21 and the second base portion 22 are offset from each other in the axial direction L, so that even if the first and second saddles 60, 70 are large, they do not interfere with each other, and large diameter pipes 95-97 can be held while preventing the bracket 10 (saddle base 20) from becoming larger in the direction perpendicular to the axial direction L.

[0052] (2) The first base portion 21, the second base portion 22, and the connecting portion 23 are arranged so as to be offset from one another in the axial direction L. The cable tie passage 40 is formed in the connecting portion 23 arranged in this manner. Therefore, the cable tie 39 can be smoothly inserted through the cable tie passage 40 without interfering with the first and second saddles 60, 70 attached to the first and second base portions 21, 22.

[0053] (3) In the cable tie passage 40, an intermediate hole 48 through which the cable tie 39 can be inserted is formed between the two insertion holes 47. As shown in Fig. 2, when the cable tie 39 is inserted through both of the two insertion holes 47, the third pipe 97 can be held in a stable state. Alternatively, as shown in Fig. 5, when the cable tie 39 is inserted through one of the insertion holes 47 and the intermediate hole 48, even a short cable tie 39 can hold the third pipe 97. In this way, the cable tie 39 has a high degree of freedom in holding the third pipe 97.

[0054] (4) The first saddle portion formed by the first saddle 60 and the first base portion 21, and the second saddle portion formed by the second saddle 70 and the second base portion 22 are arranged so as to be mutually offset in the axial direction L. As a result of this configuration, as with the above-described (1), even if the first and second saddle portions are large, they do not interfere with each other, and large diameter pipes 95-97 can be held while preventing the bracket 10 from becoming large in size in the direction perpendicular to the axial direction L.

[0055] (5) The cable tie passage 40 is disposed between the first base portion 21 and the second base portion 22 in the axial direction L, and extends in a direction intersecting the axial direction L. When the cable tie 39 is inserted after the first and second pipes 95, 96 are held, the first and second saddles 60, 70 attached to the first and second base portions 21, 22 are present on both sides of the cable tie passage 40, making it easy to position the cable tie 39 in the axial direction L and facilitate the insertion of the cable tie 39.

[0056] (6) A side wall portion 35 of the first base portion 21 and a side wall portion 35 of the second base portion 22 are provided adjacent to the cable tie passage 40. Furthermore, a side wall 50 is provided in the cable tie passage 40 adjacent to the third guide portion 49. When the cable tie 39 is inserted into the cable tie passage 40, the two side walls 35 and the side wall 50 function as guides in the axial direction L, making it easy to insert the cable tie 39.

[0057] (7) The first claw 26 is formed on the end wall 25 provided on the end of the first base portion 21 opposite to the wall 92 side. When the first saddle 60 is attached to the first saddle attachment portion 24, the first claw 26 engages with the main body 61 of the first saddle 60 in a state of contact with the end wall 25, and the first saddle 60 is disposed at a position on the first base portion 21 farthest from the second base portion 22. In addition, the second saddle 70 attached to the second base portion 22 holds the second pipe 96. Therefore, the first saddle 60 is disposed so as to be farthest from the second pipe 96 within the range of the first base portion 21. Therefore, interference between the first saddle 60 and the second pipe 96 can be suppressed. Similarly, a first claw 26 is formed on an end wall 25 provided at the end of the second base portion 22 opposite the ceiling 91 side, thereby preventing interference between the second saddle 70 and the first piping 95.

[0058] (8) The first engagement portion, which is the front wall portion 33 of the first base portion 21, and the second engagement portion, which is the front wall portion 33 of the second base portion 22, are arranged to be mutually offset in the axial direction L. In this configuration, compared to a configuration in which the first engagement portion and the second engagement portion are arranged at the same position in the axial direction L, the width of the area in which the two engagement portions and the piping cover 2 engage in the axial direction L is wider, and the piping cover 2 can be held in a more stable state.

[0059] [Other embodiments] The above embodiment can be modified, for example, as follows: The above embodiment and the following modified examples can be combined with each other to the extent that no technical contradiction occurs.

[0060] 5, the third pipe 97 may be held by bundling the first pipe 95 and the third pipe 97 together with the cable tie 39. In this case, the cable tie 39 is inserted into the intermediate hole 48 of the cable tie passage 40 and the insertion port 47 on the first base portion 21 side so as to pass between the first pipe 95 and the second pipe 96 and between the ceiling 91 and the first pipe 95.

[0061] As long as the first saddle 60 and the second saddle 70 are shifted from each other in the axial direction L so as not to interfere with each other, the first saddle attachment portion 24 and the second saddle attachment portion 38 may partially overlap each other in the axial direction L. In other words, the first base portion 21 and the second base portion 22 may be configured to partially overlap each other in the axial direction L.

[0062] The first saddle 60 and the second saddle 70 may be configured to be arranged so as to be offset from each other on a plane perpendicular to the axial direction L and not overlap each other. The saddle base 20 may be configured so that the first saddle 60 is not in contact with the end wall 25. For this purpose, for example, in the first saddle mounting portion 24, instead of the first claw 26 provided on the end wall 25, a structure similar to the mounting piece 27 and the second claw 28 may be provided.

[0063] In the saddle base 20 , the first base portion 21 may be fixed to the wall 92 , and the second base portion 22 may be fixed to the ceiling 91 . The second base portion 22 may have a different structure from the first base portion 21 .

[0064] The distance that the first base portion 21 is spaced from the wall 92 and the distance that the second base portion 22 is spaced from the ceiling 91 may be different. The cable tie passage 40 may be formed in a location other than the connecting portion 23. For example, in FIG. 4 , the cable tie passage 40 may be formed on the left side of the first base portion 21, and the first base portion 21 may be disposed between the cable tie passage 40 and the second base portion 22.

[0065] The cable tie passage 40 does not have to be formed in the saddle base 20. In the bracket 10, the saddle base 20, the first saddle 60, and the second saddle 70 may be integrally formed.

[0066] The saddle base 20 may be made of a material other than resin. For example, the saddle base 20 may be made of metal. The number of pipes held by the bracket 10 is not limited to three. The number of pipes held may be one, two, or four or more.

[0067] The bracket 10 (saddle base 20) may not hold any piping, and the saddle base 20 may function only as a cover base. The pipe cover 2 does not have to be attached to the bracket 10.

[0068] The pipes held by the bracket 10 may be ones through which gas flows. The pipes held by the bracket 10 may be other than those arranged in an entrance where a ceiling and a wall meet. For example, the bracket 10 may be used to hold a plurality of pipes that are arranged in an entrance where two walls meet and extend vertically.

[0069] [Note] The technical ideas that can be understood from the above embodiment will be described. (1) A cover base to which a cover for covering an inlet piping where a first construction surface and a second construction surface intersect is attached, a first engagement portion disposed on the first construction surface and adapted to engage with the cover; a second engagement portion disposed on the second construction surface and adapted to engage with the cover; A cover base in which the first engagement portion and the second engagement portion are arranged so as to be offset from each other in the axial direction of the pipe.
