[0009] FIG. 1 is a perspective view of a retainer 10 in an open state according to an embodiment. The retainer 10 is used to attach an elongated member to a mounting member. For example, the retainer 10 is used to secure a pipe to a mounting panel. The elongated member may be a pipe or a rod.

[0010] The holder 10 comprises a first base member 12, a first elastic member 14, a second base member 16, a second elastic member 18, an attachment portion 20, and a holding portion 22. The second base member 16, the attachment portion 20, and the holding portion 22 are integrally formed. The first base member 12 is pivotally supported by the attachment portion 20 and is rotatable, and is shown in an open state in FIG. 1 .

[0011] The first elastic member 14 and the second elastic member 18 are formed of a material that is more flexible than the first base member 12 and the second base member 16, such as a rubber material or a foam material, and abut against the elongated member. The first elastic member 14 is supported by the first base member 12, and the second elastic member 18 is supported by the second base member 16.

[0012] The mounting portion 20 is attached to a bolt. The holding portion 22 is located on the opposite side of the second base member 16 across the mounting portion 20. A pair of holding portions 22 are provided in parallel to each other and hold the elongated member.

[0013] 2 is a perspective view of retainer 10 holding an elongated member and attached to mounting panel 24. Mounting panel 24 functions as a mounting panel to which retainer 10 is attached, and may be, for example, a body panel or an interior member of a vehicle.

[0014] The first elastic member 14 and the second elastic member 18 hold the first elongated member 28a and the second elongated member 28b, and the pair of holding portions 22 hold the third elongated member 28c and the fourth elongated member 28d. The holding portion 22 prevents the third elongated member 28c and the fourth elongated member 28d from coming off by the pair of arms 22a. When the first elongated member 28a, the second elongated member 28b, the third elongated member 28c, and the fourth elongated member 28d are not particularly distinguished from one another, they are referred to as "elongated members 28." The second elastic member 18 is disposed opposite the first elastic member 14, sandwiching the elongated members therebetween.

[0015] The mounting panel 24 is formed in a flat plate shape. Stud bolts 26 are provided on the mounting panel 24. The mounting portion 20 is fixed to the stud bolts 26. As shown in FIG. 3 , the first base member 12 extends from the mounting portion 20 along the mounting panel 24, and the first base member 12 is disposed facing the mounting panel 24. Note that the retainer 10 is not limited to being attached to the underside of the mounting panel 24, but may be attached to the upper side of the mounting panel 24 or to a mounting panel 24 that intersects horizontally. Also, while the retainer 10 is shown fixed to the mounting panel 24 by the stud bolts 26, the present invention is not limited to this, and the retainer 10 may be fixed to a mounting hole formed in the mounting panel 24. In this case, the mounting portion 20 may be an anchor-shaped clip.

[0016] Fig. 3 is a perspective view of the holder 10 of the embodiment in a closed state. The holder 10 shown in Fig. 3 is in a state in which the first base member 12 is closed. Fig. 4(a) is a front view of the holder 10, and Fig. 4(b) is a top view of the holder 10.

[0017] The mounting portion 20 has an insertion hole 20a, elastic claws 20b, and a bearing portion 20c. A stud bolt 26 is inserted into the insertion hole 20a. As shown in FIG. 4(a), multiple elastic claws 20b are formed and are hooked onto the spiral groove of the stud bolt 26. The bearing portion 20c is formed in a semi-cylindrical shape on the side surface of the mounting portion 20 and rotatably supports the first base member 12.

[0018] The first base member 12 extends from the mounting portion 20. The first base member 12 has a shaft portion 30, a first through hole 32, a support portion 34, and a first locking claw portion. The shaft portion 30 extends across the width of the first base member 12, is formed in a cylindrical shape at the base end of the first base member 12, and is inserted into the bearing portion 20c. The width direction of the first base member 12 is aligned with the longitudinal direction of the elongated member 28.

[0019] The first through-hole 32 is formed in a rectangular shape and penetrates the center of the first base member 12. The support portions 34 are located on the tip side of the first base member 12 and are formed as a pair facing each other. The pair of support portions 34 support first locking claw portions, which will be described later.

[0020] The first protrusion 38 is formed midway on the first base member 12 and protrudes toward the first elastic member 14. Because the first through-hole 32 is located in the center of the first base member 12, a pair of first protrusions 38 are formed spaced apart in the width direction. The first protrusions 38 are formed in a mountain shape.

[0021] The first elastic member 14 has a first protruding portion 40, a first recessed portion 42a, a first recessed portion 42b, a first hollow portion 44, and a contact surface 46. The first protruding portion 40 is formed to protrude upward and protrudes further toward the mounting panel 24 than the first base member 12. In other words, the first protruding portion 40 protrudes from the front side of the first base member 12. This prevents the hard first base member 12 from hitting the mounting panel 24, thereby reducing impact noise caused by contact between the first base member 12 and the mounting panel 24. As shown in FIG. 3, the first protruding portion 40 has a pair of first flexible pieces 40a and is bifurcated.

[0022] The first recess 42a and the first recess 42b are arranged side by side, and the first recess 42a is formed to have a smaller diameter than the first recess 42b. The first recesses 42a and 42b have a plurality of slits cut out radially.

[0023] The first recess 44 is recessed to match the shape of the first protrusion 38 of the first base member 12. The first recess 44 is located between the first recess 42a and the first recess 42b. The first recess 44 and the first protrusion 38 are positioned so as to overlap with the first recess 42a and the first recess 42b in the extension direction 64 of the first base member 12. The radial slit portions of the first recess 42a overlap with the first recess 44 and the first protrusion 38 in the extension direction 64. The extension direction 64 of the first base member 12 is a direction along the mounting panel 24 and is perpendicular to the opposing direction of the first base member 12 and the second base member 16 in the closed state. The engagement between the first protrusion 38 and the first recess 44 prevents the first elastic member 14 from shifting relative to the first base member 12 in the extension direction of the first base member 12.

[0024] The second base member 16 extends from the mounting portion 20 in the radial direction of the stud bolt 26. The second base member 16 has an erected portion 48, a second locking claw portion 50, a second protrusion portion 52, and a second through hole. The erected portion 48 is formed like a wall and erects from the tip side of the second base member 16, facing the mounting portion 20. The second locking claw portion 50 is formed to protrude from the erected portion 48 toward the mounting portion 20. The second protrusion portion 52 protrudes toward the second elastic member 18 midway along the second base member 16.

[0025] The second elastic member 18 has a second recess 56, a second recess 58a, a second recess 58b, and a second protrusion. The second recess 58a and the second recess 58b are arranged side by side, and the second recess 58a has a smaller diameter than the second recess 58b. The second recesses 58a and 58b have multiple slits cut out radially.

[0026] The second recessed portion 56 is recessed to match the shape of the second protrusion 52 of the second base member 16. The second recessed portion 56 is located between the second recessed portion 58a and the second recessed portion 58b. The second recessed portion 56 is provided at a position overlapping with the second recessed portion 58a and the second recessed portion 58b in the extension direction 64 of the second base member 16. In the closed state, the extension direction 64 of the first base member 12 and the extension direction 64 of the second base member 16 are the same.

[0027] 5 is a cross-sectional view of the holder 10 taken along line AA in FIG. 4(b). The shaft portion 30 of the first base member 12 is received in and journaled in the bearing portion 20c of the mounting portion 20. The first protrusion 40 protrudes outward from the first through-hole 32.

[0028] The first locking claw portion 36 is locked with the second locking claw portion 50. This locking maintains the first base member 12 in a closed state. The first locking claw portion 36 is located between the second locking claw portion 50 and the second elastic member 18, and is biased from the second elastic member 18 toward the second locking claw portion 50 by contacting the inner surface 62 of the second elastic member 18. This makes it difficult for the first locking claw portion 36 and the second locking claw portion 50 to be disengaged, and also reduces rattling of the first base member 12.

[0029] The movement of the first locking claw portion 36 away from the second locking claw portion 50 along the locking surface of the second locking claw portion 50 is restricted by the abutment surface 46 of the first elastic member 14. This makes it difficult for the first base member 12 to come off the second base member 16.

[0030] The second through-hole of the second base member 16 is formed in a rectangular shape and penetrates the center of the second base member 16. The second protrusion 60 of the second elastic member 18 is inserted into the second through-hole .

[0031] Fig. 6 is a cross-sectional view of the holder 10 taken along line BB shown in Fig. 4(b) . Fig. 6 shows the holder 10 attached to the mounting panel 24.

[0032] The first protrusion 40 protrudes from the first through-hole 32 toward the mounting panel 24. The first protrusion 40 abuts against the inner surface of the first through-hole 32, making it difficult for the first base member 12 and the first elastic member 14 to shift even when subjected to vehicle vibrations.

[0033] The first protrusion 40 engages with the first through hole 32, restricting movement of the first elastic member 14 in the direction in which the first base member 12 moves away from the mounting panel 24. The direction in which the first base member 12 moves away from the mounting panel 24 is the direction in which the first protrusion 40 comes out of the first through hole 32. This allows the first through hole 32 to function both as a means for causing the first protrusion 40 to protrude into the mounting panel 24 and as a means for preventing the first elastic member 14 from coming out. In addition, the first protrusion 40 can be engaged in a state in which it protrudes from the first through hole 32.

[0034] The first through hole 32 has first inclined surfaces 32a on a pair of opposing inner surfaces of the first through hole 32, respectively, which are inclined so as to widen toward the mounting panel 24. The first protrusion 40 has a pair of first flexible pieces 40a formed so as to widen toward the mounting panel 24, and a pair of abutment surfaces 40b formed on the outer surfaces of the first flexible pieces 40a. The pair of abutment surfaces 40b are inclined so as to widen toward the mounting panel 24 and engage with the pair of first inclined surfaces 32a. In other words, the pair of abutment surfaces 40b are inclined in directions that widen toward the outside of the first through hole 32 and move away from each other.

[0035] The abutment surface 40b engages with the first inclined surface 32a so that the abutment surface 40b comes into surface contact with the first inclined surface 32a. When the pair of first flexible pieces 40a are inserted into the first through-hole 32 while they are close to each other, they spread apart due to a restoring force and are engaged with the first inclined surface 32a. This makes it easy to assemble the first elastic member 14. By arranging the pair of first flexible pieces 40a so that they spread apart toward the mounting panel 24, the first protrusions 40 can be easily bent, sufficient spacing can be secured in the width direction, and the first protrusions 40 can be easily abutted against the mounting panel 24.

[0036] The second through-hole 54 of the second base member 16 has second inclined surfaces 54a that are inclined outward and widen on a pair of inner surfaces facing each other in the width direction. The second protrusion 60 of the second elastic member 18 protrudes into the second through-hole 54 and engages with the second through-hole 54. The second protrusion 60 does not extend beyond the second base member 16, but is positioned inside the surface of the second base member 16.

[0037] The second protrusion 60 has a pair of second flexible pieces 60a formed so as to move apart outward, and a pair of contact surfaces 60b formed on the outer surfaces of the second flexible pieces 60a. The pair of contact surfaces 60b are inclined so as to widen outward and engage with the pair of second inclined surfaces 54a. This prevents the second elastic member 18 from coming off the second base member 16.

[0038] When the first base member 12 is in the closed state, the second elastic member 18 is pressed against the first elastic member 14. This allows the first elastic member 14 to be maintained in a state protruding from the first base member 12.

[0039] 7 is a diagram for explaining the operation of retainer 10 in the attached state. Resilient claw portion 20b of mounting portion 20 is engaged with threaded portion 26a of stud bolt 26, and retainer 10 is attached to mounting panel 24. Note that elongated member 28 is not shown, but in reality retainer 10 is attached to mounting panel 24 while holding elongated member 28.

[0040] The holder 10 may tilt when subjected to an input from the elongated member 28, and in FIG. 7, it is tilted with the mounting portion 20 as a fulcrum. At this time, the first protrusion 40 hits the mounting panel 24, preventing the first base member 12 from hitting the mounting panel 24.

[0041] 8A and 8B are diagrams illustrating the operation of closing the first base member 12. Fig. 8A shows the first base member 12 rotating to approach the second base member 16. The first locking claw 36 of the first base member 12 is in contact with the second locking claw 50 of the second elastic member 18. The first locking claw 36 slides over the sliding surface 50a of the second locking claw 50 and gets over the tip of the second locking claw 50. The sliding surface 50a is inclined so as to hang down toward the mounting portion 20.

[0042] 8(b), the first locking claw portion 36 climbs over the second locking claw portion 50 and further sinks into the inner surface 62 of the second elastic member 18. In this way, the second elastic member 18 can absorb the overstroke that occurs when the first locking claw portion 36 locks onto the second locking claw portion 50.

[0043] 9 is a perspective view of the holder 10 with the first elastic member 14 and the second elastic member 18 removed. The pair of first protrusions 38 and the pair of second protrusions 52 protrude toward each other.

[0044] The first protrusion 38 has an apex 38a, a first inclined surface 38b, and a first inclined surface 38c. The first inclined surface 38b slopes downward as it moves away from the apex 38a toward the mounting portion 20, and the first inclined surface 38c slopes downward as it moves closer to the mounting portion 20.

[0045] The second protrusion 52 has an apex 52a, a second inclined surface 52b, and a second inclined surface 52c. The second inclined surface 52b slopes downward as it moves away from the apex 52a toward the mounting portion 20, and the second inclined surface 52c slopes downward as it moves closer to the mounting portion 20.

[0046] The first inner surface 39 of the first base member 12 shown in FIG. 9 faces the first elastic member 14 and extends along the extension direction 64 of the first base member 12. The second inner surface 66 of the second base member 16 faces the second elastic member 18 and extends along the extension direction 64 of the second base member 16. The first inclined surfaces 38b and 38c are formed contiguous to the first inner surface 39. The second inclined surfaces 52b and 52c are formed contiguous to the second inner surface 66. In other words, the first inclined surfaces 38b and 38c are directly continuous with the flat first inner surface 39. This allows the first protrusion 38 and the second protrusion 52 to be rigid, mountain-shaped bodies. Furthermore, the first elastic member 14 and the second elastic member 18 can be configured to slide slightly relative to the first protrusion 38 and the second protrusion 52, reducing the load on the first elastic member 14 and the second elastic member 18. Even if one of the first elastic member 14 or the second elastic member 18 shifts in a direction perpendicular to the axial direction of the elongated member 28, that movement is guided along the inclination of the first protrusion 38 or the second protrusion 52 and hits the other of the first elastic member 14 or the second elastic member 18 and is compressed, thereby reducing changes in the positional relationship between the elongated members 28.

[0047] The first protrusions 38 are formed as a pair spaced apart in the width direction of the first base member 12. The second protrusions 52 are formed as a pair spaced apart in the width direction of the second base member 16. The first through hole 32 is formed between the pair of first protrusions 38. The second through hole 54 is formed between the pair of second protrusions 52. As a result, the first elastic member 14 and the second elastic member 18 are disposed between the pair of first protrusions 38 and the pair of second protrusions 52, and movement in the width direction is suppressed by the pair of first protrusions 38 and the pair of second protrusions 52.

[0048] The first protrusion 38 is located between both edges of the first through hole 32 in the extension direction 64, for example, in the center between both edges of the first through hole 32 in the extension direction 64. When the first through hole 32 becomes longer in the extension direction 64, even if the first protrusion 40 hits both edges of the first through hole 32 in the extension direction 64, the central portion of the first elastic member 14 will be displaced relative to the first base member 12. The engagement between the first protrusion 38 and the first recess 44 prevents the central portion of the first elastic member 14 from being displaced.

[0049] As shown in FIG. 3 , the first recess 44 of the first elastic member 14 has an inclined surface into which the first protrusion 38 is inserted and engages with the first inclined surfaces 38b and 38c. The second recess 56 of the second elastic member 18 has an inclined surface into which the second protrusion 52 is inserted and engages with the second inclined surfaces 52b and 52c. As shown in FIG. 3 , the first recess 44 is inclined according to the shape of the first protrusion 38 and engages with the first protrusion 38 in a surface-to-surface contact manner. The second recess 56 is inclined according to the shape of the second protrusion 52 and engages with the second protrusion 52 in a surface-to-surface contact manner. This prevents the first elastic member 14 from shifting relative to the first base member 12, and the second elastic member 18 from shifting relative to the second base member 16. Furthermore, because the inclined surfaces of the first protrusion 38 and the first recess 44 meet, slight slippage is permitted. This reduces the load on the first elastic member 14 and improves durability compared to when perpendicular walls are engaged with each other. The second elastic member 18 also provides the same effect as the first elastic member 14.

[0050] As shown in FIG. 4( a), the first protrusion 38 is formed between the pair of first recesses 42a, 42b, and the second protrusion 52 is formed between the pair of second recesses 58a, 58b. The first protrusion 38 protrudes to a height overlapping the pair of first recesses 42a, 42b when viewed in the extension direction 64 along the first base member 12. The second protrusion 52 protrudes to a height overlapping the pair of second recesses 58a, 58b when viewed in the extension direction 64 along the second base member 16. When the elongated member 28 attempts to move in the extension direction 64, the first protrusion 38 and the second protrusion 52 function as stoppers via the first elastic member 14 and the second elastic member 18, thereby suppressing the movement of the elongated member 28 in the extension direction 64.

[0051] The present invention is not limited to the above-described embodiments and modifications, and various design changes and other modifications may be made to the embodiments and modifications based on the knowledge of those skilled in the art, and such modified embodiments may also be included within the scope of the present invention.

[0052] In the embodiment, two holding portions 22 are provided side by side, but the number is not limited to this. For example, the number of holding portions 22 may be one, or may be three or more. Also, the holding portion 22 may be omitted.

[0053] In the embodiment, the first protrusion 40 passes through the first through-hole 32, but the present invention is not limited to this, and the first protrusion 40 may protrude from the side of the first base member 12 toward the mounting panel 24. Also, the present invention is not limited to this, and the first protrusion 40 may be engaged with the first through-hole 32, but the present invention is not limited to this, and the first base member 12 and the first elastic member 14 may have a different engaging structure. For example, the first base member 12 and the first elastic member 14 may be bonded together.

[0054] While the embodiment in which both sides of the first protrusion 38 are formed with the first inclined surfaces 38b, 38c has been shown, this is not limiting, and either one may be the first inclined surface. The same applies to the second protrusion 52. That is, the first protrusion 38 has first inclined surfaces 38b, 38c that incline as it approaches or moves away from the top 38a of the first protrusion 38 toward the mounting portion 20. The second protrusion 52 has second inclined surfaces 52b, 52c that incline as it approaches or moves away from the top 52a of the second protrusion 52 toward the mounting portion 20.
