[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 16, a first elastic member 18, a second base member 12, a second elastic member 14, a fixed portion 20, and a holding portion 22. The first base member 16, the fixed portion 20, and the holding portion 22 are integrally formed. The second base member 12 is pivotally supported by the fixed portion 20 and is rotatable, and is shown in an open state in FIG. 1 .
[0011] The first elastic member 18 and the second elastic member 14 are made of a material that is more flexible than the first base member 16 and the second base member 12, such as a rubber material or a foam material, and are in contact with the elongated member. The first elastic member 18 is supported by the first base member 16, and the second elastic member 14 is supported by the second base member 12.
[0012] The fixing portion 20 is attached to a bolt. The holding portion 22 is located on the opposite side of the first base member 16 across the fixing portion 20. A pair of holding portions 22 are provided in parallel 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 18 and the second elastic member 14 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 pair of arms 22a of the holding portion 22 prevent the third elongated member 28c and the fourth elongated member 28d from coming off. 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 first elastic member 18 holds the second elastic member 14 and the elongated member 28 together by sandwiching them.
[0015] The first elastic member 18 and the second elastic member 14 come into contact with the elongated member 28 held between the first base member 16 and the second base member 12, thereby suppressing vibration between the mounting panel 24 and the elongated member 28. Because vibration of the elongated member 28 can be suppressed, it is possible to prevent the second locking claw portion 36, which will be described later, from coming off the first locking claw portion 50 due to vibration.
[0016] The mounting panel 24 is formed in a flat plate shape. Stud bolts 26 are provided on the mounting panel 24. The fixing portion 20 is fixed to the stud bolts 26. As shown in FIG. 3 , the second base member 12 extends from the fixing portion 20 along the mounting panel 24, and the second 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 fixing portion 20 may be an anchor-leg clip.
[0017] 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 second 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.
[0018] The fixed part 20 has an insertion hole 20a, elastic claws 20b, and a bearing part 20c. A stud bolt 26 is inserted into the insertion hole 20a. As shown in FIG. 4(a), a plurality of elastic claws 20b are formed and are caught in the spiral groove of the stud bolt 26. The bearing part 20c is formed in a semi-cylindrical shape on the side surface of the fixed part 20 and rotatably supports the second base member 12.
[0019] The first base member 16 extends from the fixing portion 20 in the radial direction of the stud bolt 26. The first base member 16 has an erected portion 48, a first locking claw portion 50, a first protrusion portion 52, and a first through-hole (described below). The erected portion 48 is formed like a wall and erects from the tip side of the first base member 16 toward the second base member 12, facing the fixing portion 20. The first locking claw portion 50 is formed to protrude from the erected portion 48 toward the fixing portion 20. The first protrusion portion 52 protrudes toward the first elastic member 18 midway along the first base member 16.
[0020] The first elastic member 18 is disposed between the first base member 16 and the second base member 12. The first elastic member 18 has a first recess 56, a first semi-cylindrical portion 58a, a first semi-cylindrical portion 58b, and a first protrusion. The first semi-cylindrical portion 58a and the first semi-cylindrical portion 58b are disposed side by side, and the first semi-cylindrical portion 58a has a smaller diameter than the first semi-cylindrical portion 58b. The first semi-cylindrical portions 58a and 58b have a plurality of slits cut out radially.
[0021] The first recess 56 is recessed to match the shape of the first protrusion 52 of the first base member 16. The first recess 56 is located between the first semi-cylindrical portion 58a and the first semi-cylindrical portion 58b. The first recess 56 is provided at a position overlapping with the first semi-cylindrical portion 58a and the first semi-cylindrical portion 58b in the extension direction 64 of the first base member 16. In the closed state, the extension direction 64 of the first base member 16 and the extension direction 64 of the second base member 12 are the same.
[0022] The second base member 12 has a shaft portion 30, a second through hole 32, a support portion 34, and a second locking claw portion. The shaft portion 30 extends across the width of the second base member 12, is formed in a cylindrical shape at the base end of the second base member 12, and is inserted into the bearing portion 20c. The width direction of the second base member 12 is aligned with the longitudinal direction of the elongated member 28.
[0023] The second through-hole 32 is formed in a rectangular shape and penetrates the center of the second base member 12. The support portions 34 are located on the tip side of the second base member 12 and are formed as a pair facing each other. The pair of support portions 34 support second locking claw portions, which will be described later.
[0024] The second protrusion 38 is formed midway on the second base member 12 and protrudes toward the second elastic member 14. Because the second through-hole 32 is located in the center of the second base member 12, a pair of second protrusions 38 are formed spaced apart in the width direction. The second protrusions 38 are formed in a mountain shape.
[0025] The second elastic member 14 has a second protruding portion 40, a second semi-cylindrical portion 42a, a second semi-cylindrical portion 42b, a second recess 44, and a contact surface 46. The second protruding portion 40 is formed to protrude upward and protrudes further toward the mounting panel 24 than the second base member 12. In other words, the second protruding portion 40 protrudes from the front side of the second base member 12. This prevents the hard second base member 12 from hitting the mounting panel 24, thereby reducing impact noise caused by contact between the second base member 12 and the mounting panel 24. As shown in FIG. 3, the second protruding portion 40 has a pair of second flexible pieces 40a and is bifurcated.
[0026] The second half cylinder portion 42a and the second half cylinder portion 42b are arranged side by side, and the second half cylinder portion 42a is formed to have a smaller diameter than the second half cylinder portion 42b. The second half cylinder portions 42a and 42b have a plurality of slits cut out radially.
[0027] The second recess 44 is recessed to match the shape of the second protrusion 38 of the second base member 12. The second recess 44 is located between the second semi-cylindrical portion 42a and the second semi-cylindrical portion 42b. The second recess 44 and the second protrusion 38 are positioned so as to overlap with the second semi-cylindrical portion 42a and the second semi-cylindrical portion 42b in the extension direction 64 of the second base member 12. The radial slit portion of the second semi-cylindrical portion 42a overlaps with the second recess 44 and the second protrusion 38 in the extension direction 64. The extension direction 64 of the second base member 12 is a direction along the mounting panel 24 and is perpendicular to the opposing direction of the first base member 16 and the second base member 12 in the closed state. The engagement between the second protrusion 38 and the second recess 44 prevents the second elastic member 14 from shifting relative to the second base member 12 in the extension direction of the second base member 12.
[0028] 5 is a cross-sectional view of the holder 10 taken along line AA in FIG. 4(b). The shaft portion 30 of the second base member 12 is received in and journaled in the bearing portion 20c of the fixed portion 20. The second protrusion 40 protrudes from the second through-hole 32.
[0029] The first locking claw portion 50 and the second locking claw portion 36 are locked together. This locking keeps the second base member 12 in a closed state. The second locking claw portion 36 is located between the first locking claw portion 50 and the first elastic member 18, and is biased from the first elastic member 18 toward the first locking claw portion 50 by contacting the inner surface 62 of the first elastic member 18. This makes it difficult for the second locking claw portion 36 and the first locking claw portion 50 to be disengaged, and also reduces rattling of the second base member 12.
[0030] The abutment surface 46 of the second elastic member 14 abuts against the second locking claw portion 36 in the extension direction 64 of the second base member 12. Note that the abutment surface 46 may be adjacent to the second locking claw portion 36. The extension direction 64 of the second base member 12 is perpendicular to the axial direction of the elongated member 28 and perpendicular to the opposing direction of the second elastic member 14 and the second base member 12 with the elongated member 28 sandwiched therebetween. The abutment surface 46 of the second elastic member 14 restricts the movement of the second locking claw portion 36 from disengaging from the first locking claw portion 50 along the locking surface of the first locking claw portion 50. This strengthens the engagement between the first locking claw portion 50 and the second locking claw portion 36, making it difficult for the second base member 12 to disengage from the first base member 16.
[0031] When the second base member 12 is in the closed state, the first elastic member 18 and the second elastic member 14 are pressed against each other, and a reaction force may be generated in a direction that separates the first elastic member 18 and the second elastic member 14. This reaction force caused by the abutment of the first elastic member 18 and the second elastic member 14 urges the locking surfaces of the first locking claw portion 50 and the second locking claw portion 36 to mate with each other. This makes it more difficult for the first locking claw portion 50 and the second locking claw portion 36 to come out of engagement.
[0032] The first locking claw portion 50 and the second locking claw portion 36 are locked together with their locking surfaces in surface contact. In the locked state, the locking surfaces of the first locking claw portion 50 and the second locking claw portion 36 are inclined so as to rise in the upright direction as they approach the upright portion 48. In other words, the locking surface of the first locking claw portion 50 is inclined so as to hang down as it moves away from the upright portion 48. This makes it more difficult for the first locking claw portion 50 and the second locking claw portion 36 to come loose from their locked state.
[0033] The first through-hole 54 of the first base member 16 is formed in a rectangular shape and penetrates the center of the first base member 16. The first protrusion 60 of the first elastic member 18 is inserted into the first through-hole 54.
[0034] 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.
[0035] The second protrusion 40 protrudes from the second through-hole 32 toward the mounting panel 24. The second protrusion 40 abuts against the inner surface of the second through-hole 32, making it difficult for the second base member 12 and the second elastic member 14 to shift even when subjected to vehicle vibrations.
[0036] The second protrusion 40 engages with the second through hole 32, restricting movement of the second elastic member 14 in the direction in which the second base member 12 moves away from the mounting panel 24. The direction in which the second base member 12 moves away from the mounting panel 24 is the direction in which the second protrusion 40 comes out of the second through hole 32. This allows the second through hole 32 to function both as a means for causing the second protrusion 40 to protrude into the mounting panel 24 and as a means for preventing the second elastic member 14 from coming out. In addition, the second protrusion 40 can be engaged in a state in which it protrudes from the second through hole 32.
[0037] The second through hole 32 has second inclined surfaces 32a on a pair of opposing inner surfaces of the second through hole 32, respectively, which are inclined so as to widen toward the mounting panel 24. The second protrusion 40 has a pair of second flexible pieces 40a formed so as to widen as they approach the mounting panel 24, and a pair of abutment surfaces 40b formed on the outer surfaces of the second 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 second inclined surfaces 32a. In other words, the pair of abutment surfaces 40b are inclined in directions that widen toward the outside of the second through hole 32 and move away from each other.
[0038] The abutment surface 40b engages with the second inclined surface 32a so that the abutment surface 40b comes into surface contact with the second inclined surface 32a. When the pair of second flexible pieces 40a are inserted into the second through-hole 32 in a close state, they spread apart due to a restoring force and are engaged with the second inclined surface 32a. This makes it easy to assemble the second elastic member 14. By arranging the pair of second flexible pieces 40a so that they spread apart toward the mounting panel 24, the second flexible pieces 40a can be easily bent, and sufficient spacing can be secured in the width direction of the second protrusion 40, making it easy to abut against the mounting panel 24.
[0039] The first through-hole 54 of the first base member 16 has a pair of inner surfaces facing each other in the width direction, each of which has a first inclined surface 54a that is inclined so as to widen outward. The first protrusion 60 of the first elastic member 18 protrudes into the first through-hole 54 and engages with the first through-hole 54. The first protrusion 60 does not extend beyond the first base member 16, but is positioned inside the surface of the first base member 16.
[0040] The first protrusion 60 has a pair of first flexible pieces 60a formed so as to move apart outward, and a pair of abutment surfaces 60b formed on the outer surfaces of the first flexible pieces 60a. The pair of abutment surfaces 60b are inclined so as to widen outward and engage with the pair of first inclined surfaces 54a. This prevents the first elastic member 18 from coming off the first base member 16.
[0041] When the second base member 12 is in the closed state, the first elastic member 18 is pressed against the second elastic member 14. This allows the second elastic member 14 to maintain a state in which it protrudes from the second base member 12.
[0042] 7 is a diagram for explaining the operation of retainer 10 in an attached state. Resilient claw portion 20b of fixing 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.
[0043] The holder 10 may tilt when subjected to an input from the elongated member 28, and in FIG. 7 it is tilted with the fixing portion 20 as the fulcrum. At this time, the second protruding portion 40 hits the mounting panel 24, preventing the second base member 12 from hitting the mounting panel 24.
[0044] 8A and 8B are diagrams illustrating the operation of closing the second base member 12. FIG. 8A shows the second base member 12 rotating to approach the first base member 16. The second locking claw 36 of the second base member 12 is in contact with the first locking claw 50 of the first elastic member 18. The second locking claw 36 slides over the sliding surface 50a of the first locking claw 50 and passes over the tip of the first locking claw 50. The sliding surface 50a is inclined so as to hang down toward the fixed part 20.
[0045] 8(b), the second locking claw portion 36 climbs over the first locking claw portion 50 and further sinks into the inner surface 62 of the first elastic member 18. In this way, the first elastic member 18 can absorb the overstroke that occurs when the second locking claw portion 36 locks onto the first locking claw portion 50. In particular, the inclined locking surfaces of the first locking claw portion 50 and the second locking claw portion 36 can absorb the increased overstroke.
[0046] 9 is a perspective view of the holder 10 with the second elastic member 14 and the first elastic member 18 removed. The pair of second protrusions 38 and the pair of first protrusions 52 protrude toward each other.
[0047] The second protrusion 38 has an apex 38a, a second inclined surface 38b, and a second inclined surface 38c. The second inclined surface 38b slopes downward as it moves away from the apex 38a toward the fixed portion 20, and the second inclined surface 38c slopes downward as it moves closer to the fixed portion 20.
[0048] The first protrusion 52 has an apex 52a, a first inclined surface 52b, and a first inclined surface 52c. The first inclined surface 52b slopes downward as it moves away from the apex 52a toward the fixed portion 20, and the first inclined surface 52c slopes downward as it moves closer to the fixed portion 20. The second protrusion 38 protrudes from the flat inner surface 39 of the second base member 12, and the first protrusion 52 protrudes from the flat inner surface 66 of the first base member 16.
[0049] As shown in FIG. 3 , the second recess 44 is inclined according to the shape of the second protrusion 38 and engages with the second protrusion 38 in a surface-to-surface contact manner. The first recess 56 is inclined according to the shape of the first protrusion 52 and engages with the first protrusion 52 in a surface-to-surface contact manner. This prevents the second elastic member 14 from shifting relative to the second base member 12 and the first elastic member 18 from shifting relative to the first base member 16. Furthermore, since the second protrusion 38 and the second recess 44 meet at their inclined surfaces, a slight degree of slippage is permitted. This reduces the load on the second elastic member 14 and improves durability compared to when vertical walls engage with each other. The first elastic member 18 also achieves the same effects as the second elastic member 14.
[0050] 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.
[0051] 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.
[0052] In the embodiment, the second protruding portion 40 passes through the second through-hole 32, but this is not limiting, and the second protruding portion 40 may protrude from the side of the second base member 12 toward the mounting panel 24. Also, while the embodiment shows the second protruding portion 40 engaging with the second through-hole 32, this is not limiting, and the second base member 12 and the second elastic member 14 may have a different engaging structure. For example, the second base member 12 and the second elastic member 14 may be bonded together. [Explanation of symbols]
