Description

[Technical field]

[0001] The present invention relates to a saddle unit. [Background technology]

[0002] Patent Document 1 describes a holder (saddle) for holding a cord-like member such as a pipe. Such a holder is screwed to the construction surface. The cord-like member is held by a plurality of holders screwed to the construction surface, and the cord-like member is arranged to extend along the construction surface.

[0003] [Patent Document 1] JP 2023-53583 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, since the holder in Patent Document 1 is fixed to the construction surface with screws, when changing the extension direction of the rope-like member held by the holder, such as changing the degree of bending of the rope-like member, the work required for this is time-consuming. That is, after the screw fastening of the holder to the construction surface is released, the orientation of the holder is changed to match the extension direction of the rope-like member held by the holder. After changing the orientation of the holder in this way, the holder is again fixed to the construction surface with screws. The need for such time-consuming work makes it difficult to change the extension direction of the rope-like member held by the holder. [Means for solving the problem]

[0005] The means for solving the above problems and their effects will be described below. The saddle unit that solves the above problem includes a saddle for holding a rope-like member, and a base plate for fixing the saddle to a construction surface. A mounting hole is formed in the saddle. A shaft-shaped center claw portion is formed in the base plate to be inserted into the mounting hole. The center claw portion is snap-engaged with the saddle by being inserted into the mounting hole. The saddle is capable of rotating around the center claw portion.

[0006] According to the above configuration, when the center claw portion formed on the base plate is inserted into the mounting hole of the saddle, the center claw portion is snap-engaged with the saddle. As a result, the saddle for holding the cord-like member is attached to the base plate. By fixing the base plate to the construction surface, the saddle is also fixed to the construction surface. At this time, the saddle can rotate around the center claw portion relative to the base plate. Therefore, when changing the extension direction of the cord-like member held by the saddle, such as changing the degree of bending of the cord-like member, the extension direction of the cord-like member can be changed through the above-mentioned rotation of the saddle relative to the base plate. As a result, it is no longer necessary to perform a time-consuming task to change the extension direction of the cord-like member held by the saddle, and therefore it becomes easy to change the extension direction of the cord-like member.

[0007] In the saddle unit, the mounting hole extends along the center line of a cylindrical portion formed in the saddle. A circular flange extending around the center line is formed on the outer circumferential surface of the cylindrical portion. A side claw portion is formed on the base plate at a position away from the center claw portion. When the center claw portion is inserted into the mounting hole, the side claw portion is snap-engaged with the flange and is capable of rotating relative to the flange in a rotational direction around the center claw portion in this state.

[0008] According to the above configuration, when the center claw portion of the base plate is inserted into the mounting hole of the saddle, the side claw portion snaps into engagement with the flange of the cylindrical portion of the saddle. In this manner, not only is the center claw portion snapped into engagement with the saddle, but the side claw portion also snaps into engagement with the flange of the saddle, so that the saddle is firmly attached to the base plate. In addition, the side claw portion at this time is capable of rotating relative to the flange in the direction of rotation about the center claw portion. Therefore, the rotation of the saddle attached to the base plate about the center claw portion is not hindered by the snap engagement of the side claw portion with the flange.

[0009] It is considered that a plurality of the side claws are formed at intervals around the center claw. With this configuration, the attachment of the saddle to the base plate is made strong by the snap engagement of the side claws with the flange of the saddle, and the rotation of the saddle relative to the base plate about the center claw is stabilized by the snap engagement of the side claws with the flange of the saddle.

[0010] In the above saddle unit, the center claw portion has a claw for snap-engagement with the saddle when inserted into the mounting hole, and the side claw portion has a claw for snap-engagement with the flange when the center claw portion is inserted into the mounting hole, and the claw of the center claw portion and the claw of the side claw portion face each other.

[0011] According to the above configuration, the center claw portion and the side claw portion, whose claws face each other, snap-engage with the saddle, so that the attachment of the saddle to the base plate by the snap engagement is more secure. Also, the rotation of the saddle about the center claw portion relative to the base plate is more stabilized by the snap engagement of the center claw portion and the side claw portion, whose claws face each other, with the saddle.

[0012] In the above saddle unit, the saddle and the side claws are formed so that rotation about the center claw of the saddle is limited within a specified range. The saddle and the side claws are formed so that the rotation is restricted by a recessed and projecting engagement between the saddle and the side claws within the above range, and the position of the saddle can be changed within the above range by rotating the saddle about the center claw from the restricted rotation state to release the recessed and projecting engagement.

[0013] According to the above configuration, when the saddle rotates around the center claw portion relative to the base plate, the saddle and the side claw portions engage with each other and then disengage from each other, providing a certain degree of resistance to the rotation of the saddle. Due to the application of such resistance, a certain degree of moderation occurs during the rotation of the saddle. As a result, when changing the direction in which the cord-like member held by the saddle extends, it becomes easier to determine the position of the rotation direction of the saddle relative to the base plate.

[0015] Hereinafter, one embodiment of the saddle unit will be described with reference to Figs. As shown in Fig. 1, the saddle unit 11 includes a saddle 12 and a base plate 13. The saddle 12 is for holding a cord-like member such as a pipe, and can be attached to the base plate 13. The base plate 13 is for fixing the saddle 12 to a construction surface. In detail, by fixing the base plate 13 to which the saddle 12 is attached to the construction surface, the pipe held by the saddle 12 is arranged along the construction surface.

[0016] The base plate 13 is fixed to the construction surface by, for example, applying an adhesive to the base plate 13 and then directly fixing the base plate 13 to the construction surface with the adhesive.

[0017] <Saddle 12> 1 and 2, the saddle 12 includes a support portion 14, two arms 15, a first holding piece 16a, and a second holding piece 16b. The support portion 14 is a portion of the saddle 12 that is directly attached to the base plate 13. The support portion 14 includes a flat plate 17, two standing walls 18, and a cylindrical portion 19.

[0018] The flat plate 17 of the support portion 14 becomes approximately parallel to the base plate 13 when the saddle 12 is attached to the base plate 13. When the saddle 12 is attached to the base plate 13, the two standing walls 18 protrude from the flat plate 17 toward the base plate 13 with a predetermined distance between them.

[0019] As shown in FIG. 2, the cylindrical portion 19 of the support portion 14 is located between the two standing walls 18. When the saddle 12 is attached to the base plate 13, the cylindrical portion 19 protrudes from the flat plate 17 toward the base plate 13. The cylindrical portion 19 includes an intermediate wall 19a. The intermediate wall 19a extends in the left-right direction of FIG. 2 so as to be perpendicular to the two standing walls 18. The cylindrical portion 19 has surfaces that bulge in an arc shape from both sides in the thickness direction of the intermediate wall 19a. The center line of the arc-shaped surface of the cylindrical portion 19 overlaps with the intermediate wall 19a and extends in the up-down direction of FIG. 2. The cylindrical portion 19 is formed with an attachment hole 20 that extends along the center line. The outer peripheral surface of the cylindrical portion 19, i.e., the arc-shaped surface, is formed with a circular flange 21 that extends around the center line.

[0020] A plurality of protrusions 25a, 25b protruding toward the base plate 13 are formed at intervals between each other at a location on the flat plate 17 of the support portion 14 corresponding to the area between the two standing walls 18. A plurality of protrusions 25a, 25b are also formed on the flat plate 17 at a location on the opposite side across the cylindrical portion 19.

[0021] The two arms 15 of the saddle 12 are spaced apart from each other and protrude from the support portion 14 in the direction opposite to the base plate 13. One arm 15 is for supporting a first holding piece 16a, and the other arm 15 is for supporting a second holding piece 16b. The first holding piece 16a and the second holding piece 16b are curved in an arc shape.

[0022] The first holding piece 16a is connected to the one arm 15 at a predetermined position between both ends in the direction in which the curved surface extends. The first holding piece 16a is capable of being displaced in a rotational direction around the point where it is connected to the one arm 15. The second holding piece 16b is connected to the other arm 15 at a predetermined position between both ends in the direction in which the curved surface extends. The second holding piece 16b is capable of being displaced in a rotational direction around the point where it is connected to the other arm 15.

[0023] The first holding piece 16a and the second holding piece 16b are arranged so that their ends close to the support part 14 in the direction in which their curved surfaces extend, and are spaced apart from each other at the opposite ends. As shown in FIG. 1, a recess 22 is formed at each of the ends of the first holding piece 16a and the second holding piece 16b that are close to each other. Of the ends of the first holding piece 16a and the second holding piece 16b that are opposite to the ends where they are close to each other, a locking claw 23 is formed at the end of the first holding piece 16a. In addition, a locked portion 24 consisting of a number of ridges 24a is formed on the outer circumferential surface of the second holding piece 16b.

[0024] A pipe is disposed between the first holding piece 16a and the second holding piece 16b. When the pipe presses the mutually adjacent ends of the first holding piece 16a and the second holding piece 16b toward the support portion 14, the first holding piece 16a and the second holding piece 16b are displaced in a rotational direction around the points where they are connected to the arms 15. In other words, the first holding piece 16a and the second holding piece 16b close. As a result, as shown in FIG. 3, the locking claws 23 of the first holding piece 16a overlap with the multiple ridges 24a that form the locked portion 24 of the second holding piece 16b.

[0025] The ridge 24a allows the displacement of the locking claw 23 when the first holding piece 16a and the second holding piece 16b perform a closing operation. On the other hand, the displacement of the locking claw 23 when the first holding piece 16a and the second holding piece 16b perform an opening operation is prohibited because the locking claw 23 is caught on the ridge 24a.

[0026] Therefore, when the first holding piece 16a and the second holding piece 16b are closed as described above, the locking claw 23 of the first holding piece 16a is caught on the locked portion 24 (ridge 24a) of the second holding piece 16b in a state in which the piping shown by the two-dot chain line is sandwiched between the first holding piece 16a and the second holding piece 16b. As a result, the piping is held between the first holding piece 16a and the second holding piece 16b in the saddle 12.

[0027] <Base plate 13> As shown in Figs. 4 and 5, the base plate 13 has a rectangular plate-shaped main body 26. At one end in the long side direction of the main body 26 of the base plate 13, a first protrusion 33 and a second protrusion 34 protrude so as to extend along the long side direction. At the other end in the long side direction of the main body 26, a first hole 35 is formed at a position corresponding to the first protrusion 33, and a second hole 36 is formed at a position corresponding to the second protrusion 34. The first hole 35 and the second hole 36 can be fitted with the first protrusion 33 and the second protrusion 34 of the main body 26 of another base plate 13. By simultaneously fitting the first protrusion 33 into the first hole 35 and fitting the second protrusion 34 into the second hole 36, a plurality of base plates 13 can be connected to each other.

[0028] A center claw portion 27 is formed on one surface in the thickness direction of the main body 26, i.e., the center of the upper surface in Figs. 4 and 5. As shown in Fig. 6, a number of parallel grooves 26a are formed on the other surface in the thickness direction of the main body 26 so as to extend in the long side direction of the main body 26. The center claw portion 27 is used for attaching the saddle 12 to the base plate 13, and is formed in the shape of a shaft protruding from the center of the upper surface. The center claw portion 27 is formed in a forked shape. A claw 27a is formed on each of the forked ends of the center claw portion 27. A groove 27b extending in the radial direction of the center claw portion 27 is formed on each of the opposing surfaces of the forked ends of the center claw portion 27.

[0029] The center claw portion 27 can be inserted into the mounting hole 20 of the saddle 12. When the center claw portion 27 is inserted into the mounting hole 20 of the saddle 12, the claw 27a snaps the center claw portion 27 to the saddle 12. When the center claw portion 27 is snapped to the saddle 12, the insertion piece 30 is inserted into the tip of the center claw portion 27. By inserting the insertion piece 30 into the tip of the center claw portion 27 in this manner, the snap engagement of the center claw portion 27 to the saddle 12 cannot be released. A protrusion 32 is formed on each of both side surfaces in the thickness direction of the insertion piece 30. When the insertion piece 30 is inserted into the tip of the center claw portion 27 as described above, the protrusion 32 of the insertion piece 30 fits into the groove 27b of the center claw portion 27, so that the insertion piece 30 is prevented from coming out of the center claw portion 27. When the center claw portion 27 is snapped to the saddle 12, the saddle 12 can rotate around the center claw portion 27.

[0030] The insertion piece 30 before being inserted into the tip of the center claw portion 27 is integrally formed with the main body 26 via the portion to be cut 31 as shown in Figures 4 and 5. At this time, the insertion piece 30 is located corresponding to a plane intersecting with the plane of the main body 26 on which the center claw portion 27 is formed. In other words, the main body 26 of the base plate 13 includes the insertion piece 30 integrally formed as described above. This insertion piece 30 is separated from the main body 26 by cutting the portion to be cut 31. Then, the insertion piece 30 separated from the main body 26 can be inserted into the tip of the center claw portion 27 as shown in Figure 6.

[0031] A plurality of side claws 28 are also formed on one surface in the thickness direction of the main body 26, i.e., the upper surface in Figs. 4 and 5. The side claws 28 are used for mounting the saddle 12 to the base plate 13, similar to the center claws 27, and protrude in the same direction as the center claws 27 at a position away from the center claws 27. A claw 28a is formed on the tip of the side claws 28 so as to face the claw 27a of the center claws 27. When the center claws 27 are inserted into the mounting hole 20 of the saddle 12 as shown in Fig. 6, the side claws 28 are snap-engaged with the flange 21 of the cylindrical portion 19 of the saddle 12 by the claws 28a. At this time, the side claws 28 can rotate relative to the flange 21 in the rotation direction around the center claws 27. The side claws 28 are formed at intervals from one another around the center claws 27.

[0032] 7 and 8, when the saddle 12 rotates in one direction or the other around the center claw portion 27, the side claw portion 28 comes into contact with the standing wall 18 of the support portion 14 of the saddle 12. This contact of the side claw portion 28 with the standing wall 18 limits the rotation of the saddle 12 around the center claw portion 27 to within a set range. In other words, the saddle 12 and the side claw portion 28 are formed such that the rotation of the saddle 12 around the center claw portion 27 is limited to within a set range.

[0033] As shown in FIG. 2, the flat plate 17 in the support portion 14 of the saddle 12 has two projections 25a and 25b formed on the surface of the flat plate 17 facing the side claw portion 28, as described above. On the other hand, a slope 28b is formed on the tip of the side claw portion 28 in the protruding direction relative to the main body 26, narrowing the width of the side claw portion 28 toward the end face in the protruding direction. When the side claw portion 28 is snap-engaged with the flange 21, the tip of the side claw portion 28 is positioned between the two projections 25a and 25b, so that the saddle 12 and the side claw portion 28 are fitted together with a concave-convex shape. This restricts the rotation of the saddle 12 around the center claw portion 27. That is, the saddle 12 and the side claw portion 28 are formed so that the rotation is restricted by the concave-convex fit.

[0034] Furthermore, when the saddle 12 is rotated around the center claw portion 27 from the state in which the rotation is restricted as described above, the concave-convex engagement is released through the rotation. More specifically, the side claw portion 28 is guided by the slope 28b to ride over the protrusions 25a, 25b during the rotation, and the concave-convex engagement is released. This allows the position of the saddle 12 to be changed within the above range in the rotation direction. That is, the saddle 12 and the side claw portion 28 are formed so that the concave-convex engagement can be released in this manner, and the restriction on rotation due to the release of the concave-convex engagement can be released.

[0035] <How to use saddle unit 11> The saddle 12 is attached to the main body 26 of the base plate 13. More specifically, the center claw portion 27 of the main body 26 is inserted into the mounting hole 20 in the support portion 14 of the saddle 12 shown in Fig. 6. At this time, the tip of the fork-shaped center claw portion 27 shown in Figs. 4 and 5 elastically deforms so as to shrink. After passing through the mounting hole 20, the tip of the center claw portion 27 elastically expands. As a result, the center claw portion 27 is snap-engaged to the saddle 12 by the claw 27a, as shown in Fig. 6.

[0036] Furthermore, when the center claw portion 27 is inserted into the mounting hole 20 of the saddle 12, the side claw portion 28 is snap-engaged with the flange 21 of the cylindrical portion 19 of the saddle 12 by the claw 28a. When the side claw portion 28 is snap-engaged with the flange 21 in this manner, the tip of the side claw portion 28 is positioned between the two protrusions 25a, 25b as shown in Fig. 2. This results in a concave-convex fit between the saddle 12 and the side claw portion 28. This concave-convex fit between the saddle 12 and the side claw portion 28 restricts rotation of the saddle 12 around the center claw portion 27.

[0037] However, when the saddle 12 is rotated around the center claw portion 27 from the state in which the rotation is restricted as described above, the tip of the side claw portion 28 passes over the projections 25a, 25b through the rotation, and the above-mentioned concave-convex fit between the saddle 12 and the side claw portion 28 is released. This makes it possible to change the position of the saddle 12 within a set range in the rotation direction around the center claw portion 27. The position of the saddle 12 at this time is adjusted to a predetermined position within the set range.

[0038] Thereafter, the insertion piece 30 is separated from the main body 26 of the base plate 13 shown in Figures 4 and 5 by cutting the portion to be cut 31. The insertion piece 30 separated from the main body 26 is inserted into the tip of the center claw portion 27 as shown in Figure 6. This makes it impossible to release the snap engagement of the center claw portion 27 with the saddle 12. Furthermore, the insertion piece 30 is prevented from slipping out of the center claw portion 27 by the engagement between the protrusion 32 of the insertion piece 30 and the groove 27b of the center claw portion 27. In this manner, the saddle 12 is attached to the base plate 13.

[0039] As shown in FIG. 9, the saddle unit 11 is fixed to the installation surface 37 using an installation tool 38. The installation tool 38 includes a first fixing portion 39, a second fixing portion 40, a saddle inserting portion 41, and a pipe holding portion 42. The first fixing portion 39 and the second fixing portion 40 are formed in a rod shape that intersects at a substantially right angle. The saddle inserting portion 41 is formed so as to protrude on an extension line of the first fixing portion 39 from the intersection of the first fixing portion 39 and the second fixing portion 40. The pipe holding portion 42 is formed so as to protrude on an extension line of the second fixing portion 40 from the intersection of the first fixing portion 39 and the second fixing portion 40.

[0040] When fixing the saddle unit 11 to the application surface 37, the first fixing portion 39 of the application tool 38 is inserted into the end of the long pipe 43. Then, the first fixing portion 39 is screwed to the end of the pipe 43, thereby fixing the application tool 38 to the end of the pipe 43. Then, the saddle insertion portion 41 of the application tool 38 is inserted between the first holding piece 16a and the second holding piece 16b of the saddle 12, and further between the recesses 22 formed at the adjacent ends of the first holding piece 16a and the second holding piece 16b.

[0041] In this state, when the tube 43 is raised so that the saddle insertion portion 41 faces upward, the saddle insertion portion 41 supports the support portion 14 of the saddle 12, and the intersection of the first fixing portion 39 and the second fixing portion 40 supports the first holding piece 16a and the second holding piece 16b of the saddle 12. At this time, the saddle unit 11 is in a state in which the saddle 12 is facing downward and the surface opposite the saddle 12 is facing upward. In the example of Fig. 9, the base plate 13 of the saddle unit 11 supported by the tube 43 is connected to the base plate 13 of another saddle unit 11.

[0042] Then, after applying adhesive to the surface of the base plate 13 of the saddle unit 11 opposite the saddle 12, the saddle unit 11 is pressed against the application surface 37 by the tube 43 so that the surface comes into contact with the application surface 37. This fixes the saddle unit 11 to the application surface 37 by the adhesive. Since the surface of the body 26 of the base plate 13 to which the adhesive is applied has a large number of grooves 26a (FIG. 6) formed thereon, the saddle unit 11 is firmly fixed to the application surface 37 by the adhesive. Thereafter, the tube 43 is moved together with the application tool 38 in a direction away from the application surface 37, whereby the saddle insertion portion 41 of the application tool 38 is pulled away from the saddle 12.

[0043] The saddle 12 of the saddle unit 11 fixed to the application surface 37 is capable of holding a pipe 45 shown in Fig. 10. An application tool 38 is also used for the task of holding the pipe 45 on the saddle 12. That is, after inserting the second fixing part 40 of the application tool 38 into the end of the pipe 43, the second fixing part 40 is screwed to the end of the pipe 43, whereby the application tool 38 is fixed to the end of the pipe 43. The pipe holding part 42 of the application tool 38 is capable of holding the pipe 45 by placing it thereon.

[0044] With the piping 45 placed on the pipe holding portion 42, the pipe 43 to which the construction tool 38 is fixed is moved as follows: That is, the piping 45 placed on the pipe holding portion 42 is inserted between the first holding piece 16a and the second holding piece 16b of the saddle 12, and further, the ends of the first holding piece 16a and the second holding piece 16b that are close to each other are pressed against the construction surface 37. As a result, the first holding piece 16a and the second holding piece 16b are displaced in a rotational direction about the points where they are connected to the respective arms 15, thereby performing a closing operation.

[0045] As a result, as shown in Fig. 3, with the piping 45 sandwiched between the first holding piece 16a and the second holding piece 16b, the locking claw 23 of the first holding piece 16a is caught on the locked portion 24 (ridge 24a) of the second holding piece 16b. In this way, the piping 45 is held between the first holding piece 16a and the second holding piece 16b in the saddle 12. Thereafter, the construction tool 38 is separated from the piping 45 by moving the pipe 43 (Fig. 10) downward.

[0046] Next, the effects of the saddle unit 11 of this embodiment will be described. (1) When the center claw portion 27 formed on the main body 26 of the base plate 13 is inserted into the mounting hole 20 of the saddle 12, the center claw portion 27 is snapped into engagement with the saddle 12. This attaches the saddle 12 to the base plate 13. By fixing the base plate 13 to the installation surface 37, the saddle 12 is also fixed to the installation surface 37. The saddle 12 can rotate about the center claw portion 27 relative to the base plate 13. Therefore, when changing the extension direction of the pipe 45 held by the saddle 12, such as by changing the magnitude of the bend of the pipe 45, the extension direction of the pipe 45 is allowed to be changed through the above-mentioned rotation of the saddle 12 relative to the base plate 13. As a result, it is no longer necessary to perform a laborious operation to change the extension direction of the pipe 45 held by the saddle 12, and therefore it becomes easy to change the extension direction of the pipe 45.

[0047] (2) When the center claw portion 27 is inserted into the mounting hole 20 of the saddle 12, the side claw portion 28 of the main body 26 of the base plate 13 is snap-engaged with the flange 21 of the cylindrical portion 19 of the saddle 12. In this manner, not only is the center claw portion 27 snap-engaged with the saddle 12, but the side claw portion 28 is also snap-engaged with the flange 21 of the saddle 12, so that the attachment of the saddle 12 to the base plate 13 is strong. In addition, the side claw portion 28 at this time can rotate relative to the flange 21 in the rotation direction about the center claw portion 27. Therefore, the rotation of the saddle 12 attached to the base plate 13 about the center claw portion 27 is not hindered by the snap engagement of the side claw portion 28 with the flange 21.

[0048] (3) A plurality of side claws 28 are formed at intervals around the center claw 27. Therefore, the attachment of the saddle 12 to the base plate 13 is made strong by the snap engagement of the plurality of side claws 28 with the flange 21 of the saddle 12. Furthermore, the rotation of the saddle 12 about the center claw 27 with respect to the base plate 13 is stabilized by the snap engagement of the plurality of side claws 28 with the flange 21 of the saddle 12.

[0049] (4) The center claw portion 27 has a claw 27a for snap-engagement with the saddle 12 when inserted into the mounting hole 20. The side claw portion 28 has a claw 28a for snap-engagement with the flange 21 when the center claw portion 27 is inserted into the mounting hole 20. The claw 27a of the center claw portion 27 and the claw 28a of the side claw portion 28 face each other. In this case, the center claw portion 27 and the side claw portion 28, whose claws 27a and 28a face each other, snap-engage with the saddle 12, so that the attachment of the saddle 12 to the base plate 13 by the snap engagement is more secure. In addition, the rotation of the saddle 12 about the center claw portion 27 with respect to the base plate 13 is more stabilized by the snap engagement of the center claw portion 27 and the side claw portion 28, whose claws 27a and 28a face each other, with the saddle 12.

[0050] (5) The saddle 12 and the side claws 28 are formed so that the rotation of the saddle 12 around the center claw 27 is limited within a set range. When the saddle 12 rotates around the center claw 27 relative to the base plate 13, the saddle 12 and the side claws 28 engage with each other and then disengage from each other, providing a certain degree of resistance to the rotation of the saddle 12. Due to the application of such resistance, a certain degree of moderation occurs during the rotation of the saddle 12. As a result, when changing the direction in which the piping 45 held by the saddle 12 extends, it becomes easier to determine the position of the saddle 12 in the direction of the rotation relative to the base plate 13.

[0051] (6) When the center claw portion 27 of the base plate 13 is inserted into the mounting hole 20 of the saddle 12, the tip of the fork-shaped center claw portion 27 shrinks. Then, when the tip of the center claw portion 27 passes through the mounting hole 20, the tip spreads, causing the center claw portion 27 to snap-engage with the saddle 12. When the insertion piece 30 is inserted into the tip of the center claw portion 27 while the center claw portion 27 is in this snap-engaged state with the saddle 12, it becomes impossible to release the snap engagement of the center claw portion 27 with the saddle 12. This makes it difficult for the saddle 12 to come off the base plate 13.

[0052] (7) The insertion piece 30 is integrally formed with the main body 26 of the base plate 13 via the portion to be cut 31. This insertion piece 30 is cut off from the main body 26 of the base plate 13 at the portion to be cut 31 when in use. The cut-off insertion piece 30 is then inserted into the tip of the center claw portion 27. Since the insertion piece 30 is thus integrally formed with the main body 26 of the base plate 13 before use, loss of the insertion piece 30 before use is suppressed.

[0053] 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. The base plate 13 may be fixed indirectly to the construction surface as follows: The base plate 13 may be screwed to a piece of plywood or the like, an adhesive may be applied to the plywood, and then the plywood and the base plate 13 may be fixed to the construction surface together with the adhesive.

[0054] The insert piece 30 does not necessarily have to be formed integrally with the main body 26 of the base plate 13 . The insert piece 30 may be omitted.

[0055] When the insertion piece 30 is omitted, the center claw portion 27 does not necessarily have to be formed in a fork shape. The recessed and projecting engagement between the saddle 12 and the side claw portion 28 does not necessarily have to be performed.

[0056] The claw 27a of the center claw portion 27 and the claw 28a of the side claw portion 28 do not necessarily need to face each other, and may be misaligned in the rotation direction around the center line of the center claw portion 27. Only one side claw portion 28 may be formed.

[0057] The side claw portion 28 may be omitted. In this case, it is not necessary to form the flange 21 on the saddle 12. The saddle unit 11 may hold a cord-like member other than the pipe 45 .

[0058] Next, the technical concept that can be understood from the above embodiment will be described. (A) In the saddle unit according to claim 1, The center claw portion is formed with a fork shape so that when the center claw portion is inserted into the mounting hole, the center claw portion is snap-engaged with the saddle, the base plate includes an insertion piece that can be inserted into a tip of the center claw portion, The insertion piece is inserted into the tip of the center claw portion while the center claw portion is snap-engaged to the saddle, thereby making it impossible to release the snap engagement of the center claw portion with the saddle.

[0059] According to the above configuration, when the center claw portion of the base plate is inserted into the mounting hole of the saddle, the tip of the split-tip shaped center claw portion shrinks. Then, when the tip of the center claw portion passes through the mounting hole, the tip expands, and the center claw portion snaps into the saddle. When the insertion piece is inserted into the tip of the center claw portion while the center claw portion is snap-engaged to the saddle in this manner, it becomes impossible to release the snap engagement of the center claw portion with the saddle. This makes it difficult for the saddle to come off the base plate.

[0060] (B) The saddle unit according to (A), wherein the insertion piece is integrally formed with the base plate via a portion to be cut.

[0061] According to the above-mentioned configuration, the insert piece is cut off from the base plate at the intended cutting portion. Then, the cut-off insert piece is inserted into the tip of the center claw portion. Since the insert piece is integrally formed with the base plate before use, the loss of the insert piece before use is suppressed.

[0062] (C) A saddle for holding a cord-like member and a base plate for fixing the saddle to a construction surface, The saddle is provided with a mounting hole. The base plate is formed with a shaft-shaped center claw portion that is inserted into the mounting hole, The center claw portion is formed in a fork shape, so that when the center claw portion is inserted into the mounting hole, the center claw portion is snap-engaged with the saddle, The saddle is rotatable about the center claw portion, the base plate includes an insertion piece that can be inserted into a tip of the center claw portion, The insertion piece is inserted into the tip of the center claw portion while the center claw portion is snap-engaged to the saddle, thereby making it impossible to release the snap engagement of the center claw portion with the saddle.

[0063] According to the above configuration, when the center claw portion formed on the base plate is inserted into the mounting hole of the saddle, the tip of the split-tip shaped center claw portion shrinks. Then, when the tip of the center claw portion passes through the mounting hole, the tip expands, and the center claw portion snaps into the saddle. When the insertion piece is inserted into the tip of the center claw portion while the center claw portion is in this snap-engaged state with the saddle, it becomes impossible to release the snap engagement of the center claw portion with the saddle. In this way, the saddle for holding the cord-like member is attached to the base plate. By fixing this base plate to the construction surface, the saddle is also fixed to the construction surface.

[0064] At this time, the saddle can rotate around the center claw portion relative to the base plate. Therefore, when changing the extension direction of the cord-like member held by the saddle, such as changing the degree of bending of the cord-like member, the extension direction of the cord-like member can be changed through the above-mentioned rotation of the saddle relative to the base plate. As a result, since it is no longer necessary to perform a time-consuming task to change the extension direction of the cord-like member held by the saddle, it becomes easy to change the extension direction of the cord-like member. In addition, since the insert piece is inserted into the tip of the center claw portion, it becomes impossible to release the snap engagement of the center claw portion with the saddle, so that the saddle is less likely to come off the base plate.

[0065] (D) The saddle unit according to (C), wherein the insertion piece is integrally formed with the base plate via a portion to be cut.

[0066] According to the above-mentioned configuration, the insert piece is cut off from the base plate at the intended cutting portion. Then, the cut-off insert piece is inserted into the tip of the center claw portion. Since the insert piece is integrally formed with the base plate before use, the loss of the insert piece before use is suppressed.

[0067] (E) A base plate for fixing a saddle capable of holding a cord-like member to a construction surface, The base plate is formed with a shaft-shaped center claw portion that is inserted into a mounting hole formed in the saddle, The center claw portion is formed into a fork shape so that when inserted into the mounting hole, the base plate is snap-engaged with the saddle so that the saddle can rotate around the center claw portion.

[0068] According to the above configuration, when the center claw portion formed on the base plate is inserted into the mounting hole of the saddle, the tip of the split-shaped center claw portion shrinks. Then, when the tip of the center claw portion passes through the mounting hole, the tip expands, and the center claw portion snaps into engagement with the saddle. In this way, the saddle for holding the cord-like member is attached to the base plate. By fixing this base plate to the construction surface, the saddle is also fixed to the construction surface.

[0069] At this time, the saddle can rotate about the center claw with respect to the base plate. Therefore, when changing the extension direction of the cord-like member held by the saddle, such as changing the degree of bending of the cord-like member, the extension direction of the cord-like member can be changed by the rotation of the saddle with respect to the base plate. As a result, it is no longer necessary to perform a time-consuming task to change the extension direction of the cord-like member held by the saddle, and it becomes easy to change the extension direction of the cord-like member.

[0070] (F) an insert piece that can be inserted into a split end portion of the center claw portion that is snap-engaged with the saddle; The base plate described in (E) is configured so that the insertion piece is inserted into the tip of the center claw portion while the center claw portion is snap-engaged to the saddle, thereby making it impossible to release the snap engagement of the center claw portion with the saddle.

[0071] According to the above configuration, when the center claw portion of the base plate is inserted into the mounting hole of the saddle, the tip of the split-tip shaped center claw portion shrinks. Then, when the tip of the center claw portion passes through the mounting hole, the tip expands, and the center claw portion snaps into the saddle. When the insertion piece is inserted into the tip of the center claw portion while the center claw portion is snap-engaged to the saddle in this manner, it becomes impossible to release the snap engagement of the center claw portion with the saddle. This makes it difficult for the saddle to come off the base plate.

[0072] (G) The base plate according to (F), wherein the insertion piece is integrally formed via a portion to be cut.

[0073] According to the above-mentioned configuration, the insert piece is cut off from the base plate at the intended cutting portion. Then, the cut-off insert piece is inserted into the tip of the center claw portion. Since the insert piece is integrally formed with the base plate before use, the loss of the insert piece before use is suppressed. [Explanation of symbols]
