Japanese Utility Model Publication No. 6-35823 (Claim 1 etc.)

  By the way, in recent years, if the pipes have different diameters by about 1 to 2 mm, the pipes having different diameters are held by one holding member, and the cost is reduced by sharing the holding member. In this case, if a holding member as described in Patent Document 1 is used to hold a pipe having a diameter slightly smaller than the diameter of the recess, the pipe can be pressed with a lip, but the pressing force is insufficient and the pipe is There is a problem that it is easy to move in the axial direction. Such a problem is likely to occur particularly when the pipe and the holding member are attached to the vehicle with the pipe held on the holding member.

  Accordingly, an object of the present invention is to solve the above-mentioned problems of the prior art, and to provide a holding member that can hold and suppress a shift in the axial direction of a pipe.

  The holding member according to the present invention is a holding member that holds and holds a pipe, and is provided so as to be opposed to the groove part on which the pipe is placed and from both ends in the width direction of the groove part. The groove portion and a pair of sandwiching portions for holding the piping by elastic force thereof are provided, and a concave portion is provided in the center portion in the width direction of the groove portion. The holding member of the present invention can hold the piping by pressing it against the center portion in the width direction of the groove portion by the pair of holding portions. Since the recess is provided in the central portion in the width direction of the groove portion, the pipe is brought into contact with the recess, so that a frictional force is generated between the pipe and the edge of the recess so that the axial displacement is prevented. Can be suppressed.

  It is preferable that the recesses are arranged in line along the longitudinal direction of the pipe. By being provided in this way, more concave portions are brought into contact with the pipe, the frictional force is increased, and the shift in the axial direction can be reliably suppressed.

  It is preferable that an elastic body is embedded in the recess. Since the elastic body is embedded, the frictional force generated between the pipe and the edge of the recess is increased, and the shift in the axial direction can be more reliably suppressed.

  According to the holding member of the present invention, it is possible to obtain an excellent effect that the holding in the axial direction can be suppressed.

(Embodiment 1)
Embodiment 1 of a holding member is demonstrated using FIGS. 1-4. The holding member in this embodiment is for holding piping, such as a brake tube of a vehicle, for example, and arranging piping to a vehicle by being attached to a vehicle in this state.

  As shown in FIG. 1, the holding member 1 includes a base 11, a groove portion 12, and a support portion 31 and a sandwiching portion 33 (details will be described later) provided as a pair with the groove portion 12 interposed therebetween. The holding member 1 is molded from a resin such as ABS resin. As shown in FIG. 2, when the cylindrical pipe I is installed on the holding member 1, the base 11 that is orthogonal to the axial direction and the axial direction is the direction that coincides with the axial direction of the pipe I when viewed from above. The direction that coincides with the width direction is defined as the width direction.

  A groove 12 is provided along the axial direction at the center of the base 11 in the width direction. The groove part 12 is comprised from the curved surface from which the cross section of the width direction becomes a substantially semicircle shape. A cylindrical pipe I that substantially matches the diameter of the groove 12 is disposed in the groove 12 (see FIG. 2). In the present embodiment, the entire wall surface of the groove portion 12 is the bottom surface of the groove portion 12.

  In the central portion R in the width direction of the wall surface of the groove portion 12, a plurality (five in this embodiment) of concave portions 21 are arranged at predetermined intervals along the axial direction. Each of the recesses 21 has a circular opening, and the opening of each recess 21 has the same shape. In addition, in this embodiment, although the recessed part 21 is not penetrated, each may be a through-hole.

  At both ends in the width direction of the base 11, support portions 31 are extended in the opposite direction to the groove portion 12 (that is, upward in the state of FIG. 2). Each support part 31 is provided over the axial direction at the end of the base 11. Each support portion 31 is bent toward the inside of the base 11 at a bent portion 32. Each support portion 31 is provided with a clamping portion 33 on the inner side of the bent portion 32. That is, a pair of sandwiching portions 33 that are formed symmetrically are extended from both ends of the base 11 in the width direction so as to face the groove portion 12.

  As shown in FIG. 3, each of the holding portions 33 extends obliquely downward in FIG. 3 from the bent portion 32 toward the groove portion 12. The front end of the clamping part 33 is a claw part 34 that is slightly wider, and the claw part 34 clamps the pipe I between the groove part 12. That is, the clamping part 33 is clamped by pressing the pipe against the groove part 12 at the part where the claw part 34 is widened by the elastic force. In addition, when the piping I is inserted, these clamping part 33 and the nail | claw part 34 bend | fold further inside in the bending part 32, and, thereby, the piping I is inserted in the groove part 12. FIG.

  The pipe I is clamped by a pair of clamping parts 33 (claw parts 34) on both sides thereof, so that the pipe I has a substantially equal shape in the opposite direction from the claw part 34 (clamping part 33) to the diagonally downward direction in the width direction. Force is input. Since the directions in which the forces from the respective claw portions 34 are input are opposite to each other, the forces in the width direction are balanced, and a vertically downward force F is generated on the pipe I toward the groove portion 12. Thereby, the piping I is pressed vertically downward, and the piping I is clamped and fixed by the groove portion 12 and the clamping portion 33.

  And when the piping I is pressed by the vertically downward force F, the piping I will be pressed by the center part R located in the lowest part among the wall surfaces which comprise the groove part 12. FIG. In this case, since the concave portion 21 is provided in the central portion R of the groove portion 12 as described above, a frictional force is generated between the pipe I and the edge of the concave portion 21 when the pipe I is likely to slide in the axial direction. Since the pipe I is less likely to move in the axial direction, the displacement of the pipe I in the holding member 1 in the axial direction can be suppressed.

  As described above, in the present embodiment, the concave portion 21 is formed in the central portion R of the groove portion 12 to which the force by the clamping portion 33 is most applied, so that the axial movement of the pipe I is most efficiently regulated. The piping I can hardly be displaced in the axial direction. This is not only in the case of holding a pipe that substantially matches the diameter of the groove portion 12 as in the pipe I, but even if a pipe having a diameter smaller than the diameter of the groove portion 12 is arranged, the movement in the axial direction is ensured. Can be regulated.

  This point will be described with reference to FIG. FIG. 4 is a schematic diagram showing a case where the holding member 1 holds the pipe II having a slightly smaller diameter (about 1 to 2 mm) than the pipe I.

  As shown in FIG. 4, when a pipe II having a diameter smaller than that of the pipe I is disposed on the holding member 1, a gap is generated between the wall surface of the groove 12 and the pipe II and the contact portion is reduced. Moreover, since the pressing force from the clamping part 33 also reduces, holding | maintenance force will fall rather than the case where the piping I is hold | maintained.

  However, in the case of the holding member 1 of the present embodiment, even in the case of the pipe II, the pipe II can be held in a state of being pressed against the groove part 12 by the elastic force of the pair of sandwiching parts 33 (claw parts 34). . That is, similar to the pipe I shown in FIG. 3, substantially equal force is input to the pipe II in the opposite direction from the claw part 34 toward the diagonally downward direction in the width direction by the elastic force of the clamping part 33. A vertical downward force F directed to the pipe II is generated on the pipe II. As a result, the pipe II is sandwiched and held between the pair of sandwiching portions 33 and the groove portion 12.

  And the piping II is pressed by the center part R located in the lowest position among the wall surfaces which comprise the groove part 12 by the piping II being pressed by the downward force F. That is, even when the pipe II having a slightly different diameter is placed in the groove portion 12, the pipe II is pressed against the central portion R and comes into contact with the concave portion 21 provided in the central portion R. If it seems to slip, a frictional force will arise between the piping II and the edge of the recessed part 21, and the shift | offset | difference to the axial direction in the holding member 1 of the piping II can be suppressed.

  Therefore, in the present embodiment, for example, even when the pipe diameter is slightly smaller than the groove portion 12, the pipe can be reliably held, and the pipe is fixed to the vehicle with the holding member 1 fixed. Even if the pipe is likely to be displaced in the axial direction, the recess 21 can suppress the displacement in the axial direction.

(Embodiment 2)
The present embodiment is the same as the first embodiment except that the shape of the holding member 2 is partially different. This embodiment will be described with reference to FIGS. Note that the same reference numerals are assigned to the same components as those in the first embodiment. In addition, when a cylindrical pipe I is installed as shown in FIG. 6, as in the first embodiment, a direction that coincides with the axial direction of the pipe I when viewed from above is an axial direction and a base orthogonal to the axial direction. The direction coinciding with the width direction of the table 11 is defined as the width direction.

  In the present embodiment, the groove portion 12 of the base 11 is further provided with a base recess 41 at the bottom thereof. The base recess 41 is formed at both ends of the groove 12 in the axial direction, and is open at both ends of the base 11 in the axial direction. Each base recess 41 is rectangular in top view and is isolated by a wall 42. A plate-like portion 43 is provided on the wall portion 42 that isolates each base recess 41. The plate-like portion 43 has a rectangular plate shape provided in the axial direction and is separated from the base 11. The central portion of the plate-like portion 43 is supported by the wall portion 42, and both end portions in the axial direction are free ends. A pipe I (see FIG. 6) is placed on the plate-like portion 43. That is, the plate-like portion 43 functions as the bottom surface of the groove portion 12.

  As shown in FIG. 8, the plate-like portion 43 is located slightly above the central portion supported by the wall portion 42 at both ends in the axial direction when the pipe I is not provided. That is, the plate-like portion 43 is substantially V-shaped in the axial direction. And the recessed part 21 is formed in the both ends in the axial direction of the plate-shaped part 43. As shown in FIG.

  In the second embodiment, when the pipe I is installed on the holding member 2, the portion where the concave portions 21 at both ends of the plate-like portion 43 are pressed back by the pipe I, that is, the wall portion. It acts like a leaf spring around 42. Therefore, since the force for clamping the pipe I between the pair of clamping parts 33 and the groove part 12 is further increased, in this embodiment, the diameter of the pipe is slightly larger than the diameter of the pipe I, that is, the diameter of the groove part 12. Even if becomes smaller, the plate-like portion 43 pushes back the pipe I, so that it can be held more reliably. That is, even if the diameter of the pipe is different from the diameter of the pipe I, the pipe I can be pressed against each other by the claw part 34 and the plate-like part 43, and the holding force with respect to the pipe rather than the holding member 1 of the first embodiment. Can be secured.

Also in such a holding member 2, as shown in FIG. 7, when the pipe I is installed, the pair of clamping parts 33 (claw parts 34) with respect to the pipe I toward the central part R of the plate-like part 43. A vertically downward force F is applied. A vertical upward force F ₂ is applied to the pipe I from the plate-like portion 43. As a result, the pipe I is fixed and held from above and below.

  And the recessed part 21 is each provided in the both ends in the axial direction of the plate-shaped part 43 so that it may be located in the center of the width direction. In the present embodiment, the concave portion 21 is a circular through hole in a top view. The shape of the through hole is not limited to a circle. Since the concave portion 21 is formed at a position in contact with the pipe I regardless of the diameter of the pipe I, even if the pipe I is likely to be displaced in the axial direction, The axial displacement can be more reliably prevented by the frictional force. That is, according to the present embodiment, the concave portion 21 is provided in the central portion in the width direction of the plate-like portion 43 constituting the bottom surface of the groove portion 12 on which the pipe I is placed, so that the pipe portion I is placed in the groove portion 12. When the piping I is held by the sandwiching portion 33 and the plate-like portion 43 of the groove portion 12, the concave portion 21 is pressed more strongly against the piping I, so that the displacement in the axial direction can be more reliably suppressed. it can.

(Embodiment 3)
In the present embodiment, the holding member 3 is different from the first embodiment in that an elastic body is provided in the recess 21. Note that the same reference numerals are assigned to the same components as those in the first embodiment.

  As shown in FIG. 9, in the present embodiment, rubber 51 as an elastic body is provided in each recess 21 arranged in the center portion R in the width direction of the bottom surface of the groove portion 12. The rubber 51 can suppress the displacement of the pipe I in the axial direction when the pipe I is installed in the groove portion 12.

  The rubber 51 is provided so as to protrude from the surface of the groove 12 where the recess 21 is formed in a state before use. By protruding in this way, the rubber 51 first contacts the pipe I when the pipe I is inserted into the groove 12 of the holding member. Since the frictional force between the rubber 51 and the pipe I is further improved by the contact between the rubber 51 and the pipe I, the shift in the axial direction of the pipe I in the groove portion 12 can be more reliably suppressed.

  In this case, for example, a rubber plate may be attached to the central portion R. However, when the rubber plate is attached, the rubber may be crushed when the pipe I is installed, and it may be difficult to insert the pipe I. It is done. In addition, the frictional force is greater when the protruding rubber 51 is in contact as in this embodiment than in contact with a surface such as a rubber plate. Therefore, it is preferable to provide the rubber 51 in the recess 21 as in this embodiment.

  It should be noted that providing the rubber 51 in the recess 21 in this manner can be performed on the recess 21 of the holding member 2 according to the second embodiment, for example.

  According to the present embodiment, the recess 21 is provided at the center in the width direction of the groove 12 where the pipe I is placed, and the elastic body (rubber 51) is further embedded in the recess 21, so that the groove 12. Since the frictional force with respect to the piping I is improved when the piping I placed on the holding portion 33 and the groove portion 12 is held, the displacement of the piping I in the axial direction can be most effectively suppressed.

  The shape and number of the recesses 21 are not limited to the above-described embodiment. For example, if the base 11 is provided short in the axial direction, only one recess 21 may be provided. Moreover, although the shape of the opening part of the recessed part 21 is circular in this embodiment, it is not limited to this. For example, it may be formed in a polygonal shape when viewed from above, but is preferably a circular shape in view of ease of manufacturing.

  The present invention is not limited to the embodiment described above. For example, the shapes of the holding members 1, 2, and 3 are not limited as long as the object of the present invention can be achieved.

  In the present embodiment, a brake tube is used as an example of piping, but the present invention is not limited to this. Any pipe may be used as long as it is used inside the vehicle, or it may be a pipe used in other devices. The pipe may be a metal pipe or a resin tube.
