Description

  TECHNICAL FIELD The present invention relates to a piping / routing guide bracket for supporting piping such as tubes and hoses arranged in a vehicle or the like and wiring of an electric wire bundle or the like.

  Flexible long objects (referred to as piping / routing in the present invention) consisting of piping such as tubes, hoses, etc., and wire bundles, etc. for transferring air, water, oil, etc., are used in various ways on the vehicle. A large number of these pipes / routings are used to secure the guide brackets fixed in place such as between the chassis frames of the vehicle so that they do not move due to the vibration of the vehicle. I support it.

  FIG. 6 shows an example of the piping / routing 1 provided between the chassis frames of the vehicle, and shows a case where a large number of nylon tubes 1a are arranged along various routes. In order to support such a nylon tube 1a, a guide bracket 2 is fixed at a predetermined position of the vehicle, and is secured by a lashing band 4 hung on a U-shaped notch 3 formed in the guide bracket 2. The nylon tube 1a is supported so as not to swing by being bundled. At this time, the nylon tube 1a that is generally widely used is soft. Therefore, when the nylon tube 1a is strongly tied with the lashing band 4, the nylon tube 1a may be deformed to deteriorate the fluid flow, or may be damaged. There may be a problem of fluid leakage, and when a wire bundle (not shown in FIG. 6) is strongly secured with the securing band 4, there may be a problem such as damage to an internal signal line. The binding band 4 secures the nylon tube 1a or the wire bundle with a predetermined predetermined strength.

  FIG. 7 shows an example of the guide bracket 2. The guide bracket 2 is provided with a fixing member 5 obtained by bending a narrow steel plate material into an L shape, and a support plate 6 is provided at one end 5 a of the fixing member 5. The other end 5b of the fixing member 5 is fixed to a predetermined portion of the vehicle by a fixing tool 7 such as a bolt. The support plate 6 has projecting portions 6a and 6b projecting on both sides in the width direction of the fixing member 5, and at the front and rear edges in the longitudinal direction of the fixing member 5 in the projecting portions 6a and 6b. The cutout portions 3a and 3a ′ having the shape of “<” and the cutout portions 3b and 3b ′ are formed to face each other. That is, FIG. 7 shows a case where a pair of cutout portions 3a and 3a ′ provided in the overhang portion 6a and a pair of cutout portions 3b and 3b ′ provided in the overhang portion 6b are provided. Reference numeral 8 denotes a straight bottom surface that forms the bottom of the U-shaped notches 3a, 3a ′, 3b, 3b ′.

  And the nylon tube 1a of the path | route extended in the width direction of this support plate 6 is mounted in the upper part of the said support plate 6, and the securing band 4 is arrange | positioned in the notch part 3a, 3a 'of the width direction one side. The nylon tube 1a is secured by squeezing with a predetermined strength, and the nylon tube 1a is secured by squeezing the nylon tube 1a with a predetermined strength by disposing a tie strap 4 at the notches 3b, 3b 'on the other side in the width direction Thus, the nylon tube 1a is supported at two locations.

  As what has the structure similar to the said guide bracket, there exists a bolt latching clip for fixing an electric wire bundle, an electrical junction box, piping, etc. to a panel (refer patent document 1).

JP 2001-173630 A

  However, the guide bracket 2 shown in FIG. 7 has the following problems.

  Since the support plate 6 of the guide bracket 2 in FIG. 7 has a configuration in which cutout portions 3a, 3a ′, 3b, 3b ′ are formed symmetrically before and after the widthwise projecting portions 6a, 6b of the fixing member 5. As shown by a solid line in FIG. 8, the nylon tube 1a arranged to extend in the width direction of the support plate 6 can be supported, but as shown by a two-dot chain line in FIG. The nylon tube 1a arranged to extend in an obliquely crossing direction may not be supported. That is, the securing band 4 is arranged in the U-shaped notches 3a, 3a ′, 3b, 3b ′ so as to support the nylon tube 1a extending in a direction obliquely intersecting with the width direction of the support plate 6 on the support plate 6. In this case, as shown in FIG. 8, the lashing band 4 is not caught by the notches 3a ′ and 3b, which may make it difficult to securely fix the nylon tube 1a.

  Further, as shown in FIG. 9, since the lashing band 4 is greatly inclined with respect to the straight bottom surface 8 of the U-shaped cutout portions 3a, 3a ′, 3b, 3b ′, stress is applied to the corner portion 4a. In some cases, the lashing band 4 may break.

  Furthermore, as described above, in the case of the nylon tube 1a arranged extending in a direction obliquely crossing the width direction of the support plate 6, as shown in FIG. The nylon tube 1a, which is generally widely used at this time, may come into contact with the surface of the tube 1a. At this time, the tying band 4 has a high hardness to maintain strength. Therefore, there is a possibility that the nylon tube 1a may be damaged when the corner 4a of the lashing band 4 repeatedly collides with the outer peripheral surface of the nylon tube 1a due to vibration of the vehicle or the like.

  As described above, the guide bracket 2 in FIG. 7 is effectively used only when supporting the nylon tube 1a in the path extending in the width direction of the support plate 6. Therefore, the nylon tube 1a extends in the other direction. In the case of being arranged, it is necessary to manufacture and support a new guide bracket 2 in which the support plate 6 is fixed to the fixing member 5 so that the width direction of the support plate 6 matches the path of the nylon tube 1a. is there.

  Therefore, since the conventional guide bracket 2 needs to be designed for each path in which the nylon tube 1a is arranged, there is a problem that the number of parts increases and the production becomes small, resulting in high cost.

  In addition, when the nylon tube 1a does not pass the planned route due to variations due to the tension of the nylon tube 1a when the actual vehicle is assembled, it is necessary to replace it with a new guide bracket 2 that matches the new route. There is a problem that the number of rework steps increases and productivity decreases.

  The present invention has been made in view of the above-described conventional problems, and intends to provide a pipe / routing guide bracket that can support pipes / routings arranged in different paths with a single guide bracket. Is.

Piping and-installing guide bracket of the present invention has a supporting lifting portion at one end of the plate-shaped fixing member, the periphery of the support portion, which is formed opposite in the longitudinal direction before and after the fixing member At least a pair of lashing band arrangement cutouts, and at least a pair of lashing band arrangement cutouts formed facing each other in a direction crossing the longitudinal direction of the fixing member,
The support portion has a circular shape, an elliptical shape, or a polygonal shape whose area is expanded so as to protrude in the width direction of the fixing member,
The cutout portion and the additional cutout portion are formed on the outer periphery of the support portion so as to include a plurality of lashing band arrangement directions in different directions .

  In the pipe / routing guide bracket of the present invention, the pipe / routing extending in the direction perpendicular to the longitudinal direction of the fixing member and arranged in the support portion is a notch formed facing the front and rear of the periphery of the support portion. Piping and wiring arranged in the support part extending in a direction crossing at an angle other than perpendicular to the longitudinal direction of the fixing member can be supported by the support part by arranging a lashing band in the part. A securing band can be arranged at an additional notch formed opposite to the longitudinal direction of the fixing member at the periphery to be supported by the support.

  In the piping / routing guide bracket, it is preferable that a bottom side of the notch portion forms a curved bottom surface.

  According to the pipe / routing guide bracket of the present invention, pipes / routings arranged in a plurality of different paths can be supported by using one guide bracket. Can be reduced and the cost can be reduced by mass production.

  By making the bottom of the notch part a curved bottom surface, even if the securing band supporting the piping / routing is deviated from a right angle, stress is concentrated on the securing band by adapting the securing band to the curved bottom surface. This can prevent problems that occur.

  Further, since the fixing member and the support portion are integrally formed by punching a plate material, there is an effect that the productivity of the guide bracket can be further increased and the cost can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows an embodiment of a pipe / routing guide bracket according to the present invention. The guide bracket 10 has an area extending from the one end 11a of a plate-like fixing member 11 in the width direction of the fixing member 11. A support portion 12 having, for example, a circular shape is formed integrally. The other end 11b of the fixing member 11 is bent into an L shape, and the other end 11b is fixed to the vehicle by a fixing tool 7 such as a bolt. It is fixed in place.

  Similarly to FIG. 7, the support portion 12 includes a pair of cutout portions 3 a and 3 a ′ and a pair of cutout portions 3 b and 3 b ′ that are opposed to each other in the longitudinal direction of the fixing member 11. ing.

  Furthermore, a pair of additional cutouts 13a and 13a ′ are provided on the periphery of the support portion 12 so as to face each other in a direction crossing the longitudinal direction of the fixing member 11 at an angle other than 90 °. A pair of additional cutout portions 13b and 13b ′ formed to face each other at an angle different from the additional cutout portions 13a and 13a ′. In the embodiment of FIG. 1, the case where two pairs of additional cutout portions 13a, 13a ′, 13b, and 13b ′ are provided is illustrated. However, the additional cutout portions are at least a pair within a range in which the strength of the support portion 12 is maintained. Any number can be provided. The support portion 12 may have an elliptical shape in addition to a circular shape, or may have a polygonal shape.

  Further, in the embodiment shown in FIG. 1, the cutout portions 3a, 3a ′, 3b, 3b ′ and the additional cutout portions 13a, 13a ′, 13b, 13b ′ are formed as a curved bottom surface 14 whose bottoms are recessed in a curved shape. . The curved bottom surface 14 may be a semicircle or a semi-ellipse.

  The guide bracket 10 can be manufactured such that the fixing member 11 and the support portion 12 are integrally formed by punching a plate material.

  The operation of the above embodiment will be described below.

  2 shows a first case where a nylon tube 1a, which is an example of a piping / routing 1 extending in a direction orthogonal to the longitudinal direction of the fixing member 11, is arranged with respect to the support portion 12 of the guide bracket 10 of FIG. In this case, the lashing band 4 is disposed at the notches 3a, 3a ′, 3b, 3b ′ formed in the front and rear of the periphery of the support 12 so as to have a predetermined strength. By squeezing, the nylon tube 1 a is supported by the support portion 12.

  FIG. 3 shows a second support example when the nylon tube 1a is disposed at an angle of about 45 ° from the upper right to the lower left of the fixing member 11 with respect to the support portion 12 of the guide bracket 10 of FIG. In this case, contrary to the inclination of the nylon tube 1a, the lashing band 4 is disposed at the notch 3a and the additional notch 3b 'formed on the upper left and lower right of the periphery of the support part 12 and predetermined. The nylon tube 1a is supported by the support portion 12 by squeezing with the strength of.

  4 shows a third example of support when the nylon tube 1a is disposed at an angle of about 45 ° from the upper left in the longitudinal direction of the fixing member 11 to the lower right with respect to the support 12 of the guide bracket 10 in FIG. In this case, contrary to the inclination of the nylon tube 1a, the securing band 4 is disposed at the notch 3b and the additional notch 3a 'formed at the upper right and lower left of the periphery of the support 12 to obtain a predetermined strength. By narrowing down, the nylon tube 1a is supported by the support portion 12. Here, the notches 3a, 3a ′, 3b, 3b ′ and the additional notches 13a, 13a ′, 13b, 13b ′ are arranged so that the nylon tube 1a and the lashing band 4 are positioned as orthogonal as possible. Select and place the lashing band 4.

  As shown in FIGS. 2 to 4, by using one guide bracket 10, the nylon tube 1 a arranged in three different paths can be supported. Thus, since the guide bracket 10 can support the nylon tube 1a arranged in a plurality of different paths with one guide bracket 10, the types of the guide bracket 10 can be reduced by common parts, and mass production is possible. Can reduce costs.

  Further, as shown in FIGS. 3 and 4, the nylon tube 1a arranged to be inclined with respect to the support portion 12 has a cutout portion 3a and an additional cutout portion 3b ′ so as to be orthogonal to the inclination of the nylon tube 1a. And the notch 3b and the additional notch 3a ′ are supported by the securing band 4 so that the notch 3a and the additional notch 3b ′ and the notch 3b and the additional notch 3a ′ It can get in and support it reliably. Furthermore, since the binding direction of the nylon tube 1a can be selected and secured so that the securing band 4 is substantially orthogonal to the nylon tube 1a, the securing band 4 is parallel to the outer peripheral surface of the nylon tube 1a. Accordingly, as shown in FIG. 10, it is possible to prevent the problem that the corner portion 4a of the lashing band 4 contacts the outer peripheral surface of the nylon tube 1a and damages the nylon tube 1a.

  Further, the lashing band 4 is supported by the curved bottom surface 14 provided in the notches 3a, 3a ′, 3b, 3b ′ and the additional notches 13a, 13a ′, 13b, 13b ′. When supporting the piping / routing 1 in a direction crossing the longitudinal direction obliquely, the lashing band 4 becomes familiar with the curved bottom surface 14, and therefore, as shown in FIG. By hitting 3, the problem that stress concentrates on the lashing band 4 and breaks can be prevented.

  As described above, when the nylon tube 1a is secured by hanging the securing band 4 on the cutout portion having the curved bottom surface 14 and tightening with a predetermined strength, there is a problem that the securing band 4 is damaged. It has been empirically obtained that there is no problem and that the nylon tube 1a is not damaged. Therefore, the freedom degree of the position which arrange | positions the lashing band 4 can be expanded.

  FIG. 5 shows a modification of the guide bracket 10 of FIG. 1. In FIG. 1, the bottoms of the cutouts 3a, 3a ′, 3b, 3b ′ and the additional cutouts 13a, 13a ′, 13b, 13b ′ are curved bottoms. 14 in contrast to the straight bottom 8 in FIG. As described above, even when the straight bottom surface 8 is used, when the piping / routing 1 in a direction obliquely crossing the longitudinal direction of the fixing member 11 is supported, the lashing band 4 and the nylon tube 1a are as orthogonal as possible. Thus, since the securing band 4 can be arranged by selecting an arbitrary notch portion, the nylon tube 1a can be safely supported by generating a large stress in the securing band 4 and preventing problems.

  Since the guide bracket 10 is manufactured by punching a plate material so that the fixing member 11 and the support portion 12 are integrally formed, the strength of the guide bracket 10 can be increased and the productivity can be further increased to reduce the cost. You can go down.

  In the above embodiment, the case where the nylon tube 1a is supported by the guide bracket 10 as an example of the piping / routing 1 is illustrated. However, the guide bracket 10 is a tube other than the nylon tube, piping such as a hose, and a wire bundle. The present invention can be similarly applied to a case where various flexible elongated objects such as routing are supported.

  The piping / routing guide bracket of the present invention is not limited to the above-described embodiments, and is not limited to the number of notches, and various other modifications are within the scope of the present invention. Of course, changes can be made.
