FIG. 1 is a perspective view of a holder 10 of an embodiment. 2(a) is a perspective view of the holder 10 viewed from the front side, and FIG. 2(b) is a perspective view of the holder 10 viewed from the rear side. 2(a) is a front view of the holder 10, and FIG. 2(b) is a rear view of the holder 10. FIG.

The holder 10 is used to attach the elongated member to the attached member. For example, the holder 10 is used to fix a long member such as a pipe or a bar to a vehicle body panel that is a member to be attached. The holder 10 can hold elongated members of different diameters, such as pipes covered with sponge material and bars with hard surfaces. The attached member is, for example, a vehicle body panel.

The holder 10 includes a fixing portion 20 fixed to the attached member and a holding portion 22 holding the elongated member. The fixed portion 20 has a flange portion 24 , a column portion 26 , a locking claw 28 and a connecting portion 30 . The flange portion 24 is formed in an umbrella shape and abuts on the surface of the vehicle body panel during installation.

A column portion 26 depends from the flange portion 24 . A pair of locking claws 28 are provided and extend from the column portion 26 toward the flange portion 24 . The locking claw 28 is locked to the rear edge of the mounting hole formed in the vehicle body panel. In the embodiment, the fixed part 20 is fixed to the mounting hole formed in the vehicle body panel, but the fixed part 20 may be fixed to a bolt projecting from the vehicle body panel. The connecting portion 30 connects the flange portion 24 and the holding portion 22 .

The holding portion 22 includes a first retaining piece 34 a , a second retaining piece 34 b (referred to as “retaining piece 34 ” when not distinguished), an elastic piece 36 , a projection 38 , a pedestal 40 , and a semi-cylindrical portion 42 . , an insertion opening 44 and a frame portion 46 . The frame portion 46 has a bottom portion 31 , a pair of side wall portions 32 erected from the bottom portion 31 , and an insertion opening 44 for an elongated member opening upward in the pair of side wall portions 32 . A pair of side wall parts 32 extend in parallel. The elongated member is inserted from the insertion opening 44 toward the bottom portion 31 and held between the pair of side wall portions 32 .

A direction in which the pair of side wall portions 32 face each other is called a facing direction F. As shown in FIG. Also, the direction along the central axis direction of the held long member is referred to as the width direction W of the side wall portion 32 . Further, the vertical direction in the drawing and the direction in which the long member is inserted between the holding portions 22 is referred to as an insertion direction I. As shown in FIG. The facing direction F is orthogonal to the width direction W and the insertion direction I, and the width direction W is orthogonal to the insertion direction I.

The retaining piece 34 extends from the upper end portion of the side wall portion 32 on the side of the insertion port 44 relative to the elastic piece 36 and is provided so as to be flexible. to stop The retainer piece 34 extends toward the bottom portion 31 so as to hang down inward in the facing direction F. A pair of retaining pieces 34 are provided, each extending from the pair of side wall portions 32 . The retaining piece 34 has a first retaining piece 34a and a second retaining piece 34b. The first retaining piece 34a and the second retaining piece 34b are separated in the width direction and bend independently. .

The first retainer piece 34a faces the elastic piece 36 in the insertion direction I, and the second retainer piece 34b faces the semi-cylindrical portion 42 in the insertion direction I. The first retainer piece 34a sandwiches the elastic piece 36 and the elongate member, and the second retainer piece 34b sandwiches the half cylinder portion 42 and the elongate member.

The elastic pieces 36 extend from the pair of side wall portions 32 and are flexibly provided. The elastic piece 36 is positioned closer to the bottom portion 31 than the retaining piece 34 and arranged to face the retaining piece 34 . Since the elastic piece 36 is provided so as to be flexible, it is possible to hold the long member even if the diameter of the long member is different.

The protrusion 38 is formed to protrude in the middle of the elastic piece 36 , details of which will be described later. The projecting portion 38 itself is formed like a rigid body, and is formed to be less flexible than the elastic piece 36 . Therefore, the projecting portion 38 can abut on the long member in the held state so as to bite into it, and it is possible to suppress the movement of the long member in the thrust direction (width direction W).

The pedestal portion 40 forms a seat surface between the pair of elastic pieces 36, as shown in FIG. 1(a). The pedestal portion 40 extends uniformly from the semi-cylindrical portion 42 to prevent excessive insertion of the elongated member. As shown in FIG. 1(b), the semi-cylindrical portion 42 is formed in a semi-cylindrical shape between the pair of side wall portions 32 and is positioned offset in the width direction W from the elastic piece 36. As shown in FIG.

FIG. 3 is an enlarged view of the holder 10 and a front view of the holder 22. FIG. The elastic piece 36 has a distal end 36a and a proximal end 36b. A distal end portion 36a of the elastic piece 36 is formed as a column extending along the width direction W. As shown in FIG. A base end portion 36b of the elastic piece 36 is a portion connected to the side wall portion 32 and formed to extend along the opposing direction F. As shown in FIG. By extending the base end side of the elastic piece 36 along the facing direction F, the upper surface 36c along the facing direction F is formed on the base end portion 36b.

The projecting portion 38 protrudes from the elastic piece 36 toward the inner side of the pair of side wall portions 32 . The projecting portion 38 is located closer to the proximal end than the distal end portion 36 a of the elastic piece 36 . That is, the projecting portion 38 is positioned so as not to protrude inward in the facing direction F from the tip portion 36a. As a result, it is possible to prevent the protrusion 38 from being displaced following the distal end portion 36a, thereby suppressing the weakening of the contact force to the long member due to the displacement.

Since the holder 10 is transported in a state where it is positioned and attached to the elongated member, it is preferable that it does not shift in the thrust direction of the elongated member during transportation. With the holding portion 22 holding the elongated member, the retaining piece 34, the tip portion 36a of the elastic piece 36, and the projecting portion 38 are provided so as to contact the elongated member. That is, the distal end portion of the retainer piece 34, the distal end portion 36a of the elastic piece 36, and the projecting portion 38 are arranged in a substantially circumferential direction so as to surround the elongated member. As a result, the projecting portion 38 can be brought into contact with the long member while the retaining piece 34 and the elastic piece 36 hold the long member, and the holder 10 moves in the thrust direction with respect to the long member. can be suppressed.

The projecting portion 38 projects from a position overlapping the base end portion 36b side of the elastic piece 36 when viewed in the width direction W as shown in FIG. That is, the projecting portion 38 is provided at a position overlapping the base end portion 36b of the elastic piece 36 in the opposing direction. Further, the projecting portion 38 is provided so as not to protrude in the insertion direction I from the base end portion 36b. As a result, the projecting portion 38 is arranged on the base end side of the elastic piece 36, so that the projecting portion 38 is prevented from being greatly displaced due to the bending of the elastic piece 36, and the weakening of the contact force to the long member due to the displacement is prevented. can be suppressed.

The projecting portion 38 is positioned so as to be shifted toward the bottom portion 31 from the upper surface 36 c of the base end portion 36 b of the elastic piece 36 . That is, the protrusion 38 does not protrude from the upper surface 36c of the base end portion 36b located on the insertion port 44 side, but protrudes from a position one step lower than the upper surface 36c. As a result, the protruding portion 38 can be arranged at a position away from the insertion opening 44, and the insertion resistance generated by contact with the long member when the long member is inserted can be suppressed. In addition, it is possible to prevent the protrusion 38 from being too close to the base end 36b and not following the bending of the elastic piece 36 at all, thereby preventing the insertion resistance from becoming too high.

The first retaining piece 34a protrudes closer to the bottom 31 than the second retaining piece 34b. That is, the first retaining piece 34a is formed longer than the second retaining piece 34b. The first retainer piece 34 a faces the elastic piece 36 . As a result, when the small-diameter elongated member is held, the long first retaining piece 34a can push the elongated member downward toward the elastic piece 36, and the projecting portion 38 does not come into contact with the small-diameter elongated member. can.

FIG. 4 is a cross-sectional view of the holder 10 shown in FIG. 3 taken along line AA. The pedestal portion 40 and the semi-cylindrical portion 42 are continuous. The semi-cylindrical portion 42 is positioned apart from the elastic piece 36 in the width direction W. As shown in FIG.

The width of the protrusion 38 is smaller than the width of the elastic piece 36 . That is, the length in the width direction W of the protrusion 38 is shorter than the length in the width direction W of the elastic piece 36 . As a result, the surface pressure when the protrusion 38 comes into contact with the long member can be increased.

The projecting portion 38 protrudes radially inward from the semi-cylindrical portion 42 and is arranged closer to the semi-cylindrical portion 42 side in the width direction W. That is, the projecting portion 38 is arranged closer to the center side of the side wall portion 32 in the width direction W. As shown in FIG. As a result, the projecting portion 38 abuts on the elongated member at the center side in the width direction W, so that the holder 10 is prevented from tilting with respect to the elongated member when it is conveyed while being held by the elongated member. be able to.

5A and 5B are diagrams for explaining the operation of the holder 10 when the holder 10 holds the long member 12. FIG. FIG. 5(a) shows a state in which the long member 12 is inserted into the insertion opening 44, contacts the retaining pieces 34, and bends so that the pair of retaining pieces 34 spreads.

In FIG. 5B, the elongated member 12 is further inserted into the bottom portion 31 side, and the pair of retainer pieces 34 are expanded so as to be able to pass through the elongated member 12 . FIG. 5(c) shows a state in which the long member 12 passes through the pair of retaining pieces 34 and abuts against the elastic piece 36, causing the elastic piece 36 to bend.

FIG. 5(d) shows a state in which the retaining piece 34 and the elastic piece 36 have returned, and the distal end portion 36a of the retaining piece 34 and the elastic piece 36 and the protrusion 38 are in contact with the long member 12. . As a result, the holding portion 22 holds the long member 12 at six points, and in particular, the protrusions 38 come into contact with the long member 12 so as to bite into the long member 12, thereby suppressing the movement of the holder 10 and the long member 12 in the thrust direction. be able to.

FIG. 6 shows a cross-sectional view of the holder 10 holding the small-diameter elongated member 12a. FIG. 6(a) shows a cross section along the facing direction F and the insertion direction I passing through the elastic piece 36, and FIG. cross section.

In FIG. 6A, the tip of the first retaining piece 34a, the tip 36a of the elastic piece 36, and the projection 38 are in contact with the long member 12a. 6(b), the long member 12a is retained by the second retainer piece 34b, but has a gap with respect to the semi-cylindrical portion 42. As shown in FIG.

FIG. 7 shows a cross-sectional view of the holder 10 holding the large-diameter elongated member 12b. 7(a) shows a cross section passing through the elastic piece 36 as in FIG. 6(a), and FIG. 7(b) shows a cross section passing through the semi-cylindrical portion 42 as in FIG. 6(b). .

In FIG. 7(a), the long first retaining piece 34a hits the long member 12b and does not return completely, and as shown in FIG. 7(b), the long member 12b is retained by the short second retaining piece 34b. . The distal end portion of the second retaining piece 34b, the distal end portion 36a of the elastic piece 36, and the protrusion 38 are in contact with the long member 12b to hold the long member 12b. In this way, even if the elongated member 12b has a large diameter, the protrusion 38 abuts against the elongated member 12b, so that the elongated member 12b and the holder 10 are restrained from moving in the thrust direction.

The large-diameter elongated member 12b is held on the semi-cylindrical portion 42 side, and the small-diameter elongated member 12a is held on the elastic piece 36 side. Therefore, there is a possibility that the elongated member 12 in the held state is tilted, but since the protrusion 38 is positioned on the center side in the width direction W, the inclination of the elongated member 12 is suppressed.

FIG. 8 is a front view of a holder 100 of a modified example. The holder 100 of the modification differs from the holder 10 shown in FIG.
