Japanese Utility Model Publication No. 7-002690 Japanese Patent Laid-Open No. 60-023611 Japanese Utility Model Publication No. 5-001084 Japanese Utility Model Publication No. 50-064874 Japanese Utility Model Publication No. 60-010978 Japanese Utility Model Publication No. 61-096720

  In addition to the above-described known clip configuration, the clip disclosed in Patent Document 1 includes a first elastic piece extending along the first arm from a connecting portion to the first arm inside the ring. A second elastic piece is formed that is connected to the free end of the first elastic piece and folds along the first elastic piece and extends along the first elastic piece. When the first elastic piece is pressed toward the first arm, When the second elastic piece is pressed toward the first elastic piece side, the second elastic piece is centered on the connection portion with the first elastic piece when the second elastic piece is pressed toward the first elastic piece. The first elastic piece and the second elastic piece are formed so that the reaction force obtained by combining the two reaction forces is directed toward the center of the ring. Yes. Accordingly, even if the outer diameter of the long member to be held is different, it is preferable that the long member can be held in contact with a fixed position of the second arm provided with the attachment portion to the attached member. The second arm is provided with an attachment portion that is attached to a member to be attached such as a panel, and the held long member can be fixed to the member to be attached. Even in such a clip, it is desired that the difference in diameter of a long member such as a wire harness can be dealt with in a wider range.

  Since the clip of Patent Document 2 has an elastic piece having a shape similar to the folded shape provided on the first arm of the clip of Patent Document 1, the long member is brought into contact with the long member at a fixed position. However, there is no configuration in which the first arm and the second arm are connected by a hinge and the first arm is pivoted around the hinge with respect to the second arm. Therefore, the clip of Patent Document 2 does not have a wide range of the diameter of the long member that can be held as compared with the clip of Patent Document 1, and is easily opened and held to hold the long member. I can't. The clip described in Patent Document 3 has a configuration in which a first arm and a second arm are connected by a hinge to form a ring, and a long member housed inside the first arm and the second arm is elastic. The elastic piece to hold is formed. The elastic piece of this clip has a shape that does not have a folded shape, its elastic range is not large, and the range of the diameter of the long member that can be held is not wide.

  The clip of Patent Document 4 has a configuration in which a first arm and a second arm are connected by a hinge to form a ring, and a long member housed inside the first arm and the second arm is elastically elastic. An elastic piece to be held is formed. Further, the connecting means of the arm is composed of a lock claw and a lock receiving part formed with a multistage ratchet claw, and the size of the ring can be changed. The elastic piece of this clip consists of a holding piece that holds the circumferential surface of the long member inside the arm, and a pair of parallel leg portions that connect the holding piece to the arm, and is long due to the elastic deflection of the parallel leg portion. The member is elastically held. This clip has a structure that can cope with the difference in the diameter of the long member by locking the lock claw having the ratchet claw and the lock receiving portion, but the holding of the long member by the elastic piece is the deformation deformation of the parallel leg portion. Therefore, the deformation range is not large, and the range of the diameter of the long member that can be held is not wide.

  The clip of Patent Document 5 is composed of a U-shaped main body and a cover for closing the main body opening, and a bridge shape is provided inside the U-shaped main body so as to elastically support the peripheral surface of the long member near the bottom. The elastic piece is provided. Further, one of the covers can be pivoted so that one of the covers is connected to the main body by a hinge and opens and closes the main body opening, and a connecting means is provided on the other end of the cover and the corresponding end of the main body. In order to be able to change the connection height, the first locking piece and the second locking piece have different heights, and both the locking pieces are connected to the end of the main body via a hinge. This clip has a bridge-shaped elastic piece formed on the main body and a difference in diameter of the long member by locking the locking claw of the cover to one of the first locking piece or the second locking piece of the main body. However, the holding of the long member by the elastic piece is due to the bending deformation of the bridge shape, and the difference in length between the first locking piece and the second locking piece cannot be increased. The range of the diameter of the long member that can be produced is not wide. Moreover, since it forms with the 1st locking piece and the 2nd locking piece, it becomes a complicated shape and operation is also troublesome. The clip of Patent Document 6 is a part of the peripheral surface of a long member accommodated by extending a resilient piece that can be bent and deformed radially inward from an inner wall surface of a ring-shaped holding portion to form a convex portion at a free end. Keeps elastic. In one embodiment, there is one elastic piece, but in another embodiment, two opposing elastic pieces are provided to hold the elongated member. The holding of the long member of the clip is based on the bending deformation of the elastic piece, the deformation range of the elastic piece is not large, and the range of the diameter of the long member that can be held is not wide.

  Accordingly, an object of the present invention is a clip for holding a long member suitable for holding a long member such as a wire harness and attaching the long member to a mounted member, and is a long member having various diameters. It is in providing the clip suitable for holding.

  In order to achieve such an object, according to the present invention, a curved first arm that holds a part of a circumferential surface of a long member such as a wire harness, and one end of the first arm are connected to each other via a hinge. A curved second arm that holds the other part of the peripheral surface of the elongated member, and the first arm and the second arm are respectively attached to the other end of the first arm and the other end of the second arm. A locking claw for holding a long member provided with connecting means for connecting so as to form a ring with both arms, wherein one of the connecting means of the first arm and the second arm is elongated. The other of the connecting means of the first arm and the second arm is a lock receiving portion having a locking shoulder that receives the lock claw and engages with the locking claw of the lock claw, and the lock claw has a longitudinal direction thereof. At least two locking claws are formed at Thus, when the lock claw is inserted into the lock receiving portion and at least one of the two locking claws is locked to the locking shoulder of the lock receiving portion, the first arm and the second arm are connected to form a ring. The clip is characterized in that the size of the ring is different when one of the at least two locking claws is locked to the locking shoulder and when the other of the at least two locking claws is locked to the locking shoulder. Is provided.

  As described above, since the sizes of the rings formed by connecting the first arm and the second arm are different, it is possible to provide a clip suitable for holding elongate members having various diameters.

  In the above clip, one of the first arm and the second arm is connected to the free end of the first elastic piece and the first elastic piece extending along the one arm from the connecting portion to the one arm inside the ring. And a second elastic piece extending back and extending along the first elastic piece. When the first elastic piece is pressed toward one arm side, the other arm is centered on a connecting portion with one arm. When the second elastic piece is pressed toward the first elastic piece, the second elastic piece is counteracted in the direction of turning toward the other arm centering on the connecting portion with the first elastic piece. The first elastic piece and the second elastic piece are formed so that a reaction force obtained by combining two reaction forces is directed toward the center of the ring. A first elastic piece and a second elastic piece are formed on each of the first arm and the second arm. In this case, a first folded shape formed by the first elastic piece and the second elastic piece of the first arm, and a second folded shape formed by the first elastic piece and the second elastic piece of the second arm, However, it is formed so as to form an axisymmetric shape around the axis in the ring.

  In the clip, one of the first arm and the second arm is formed with an attachment portion attached to a member to be attached for attaching a long member. On the other end of the first arm and the second arm, a finger hook for assisting in connecting the connecting means to the connecting means to one arm is formed at the end adjacent to the connecting means. This finger-hanging part can also be made into the shape which makes the connection cancellation | release easy when removing the hold | maintained elongate member. Furthermore, a pair of harness entry preventing pieces extending toward the center of the hinge so as to cover the hinge is formed in the portion adjacent to the hinge of the first arm and the portion adjacent to the hinge of the second arm. .

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a clip 1 for holding a long member such as a wire harness according to an embodiment of the present invention. The clip 1 is made of an integrally molded product of plastic. 2 to 5 show an operation in which the clip 1 is attached to the panel 2 as the attached member and the wire harness 3 as the long member is held and attached to the panel 2. 6 and 7 show a state where the clip 1 holds the large-diameter wire harness 3A and the small-diameter wire harness 3B.

  In FIG. 1, a clip 1 holds a curved first arm 5 that holds a part of the circumferential surface of a long member such as a wire harness, and another part of the circumferential surface of a long member such as a wire harness. A curved second arm 6 and a thin hinge 7 that rotatably connects one end of the first arm 5 and one end of the second arm 6 are provided. In the illustrated embodiment, a hook-shaped attachment portion 9 that is attached to a hole provided in a panel as a member to be attached is formed on the outer side of the second arm 6 substantially in the middle. An arm 6 is formed as the main body of the clip 1. Therefore, in the illustrated embodiment, the first arm 5 is formed as a cover that covers the open portion of the second arm, which is the main body. The first arm 5, the second arm 6, and the hinge 7 may have any width along the axial direction of the wire harness (the length in the direction perpendicular to the paper surface of FIG. 1). The length is as short as shown in FIG. 2 and the like, and may be short or long as long as there is no obstacle to holding the wire harness. Moreover, although the attaching part 9 is formed in the hook-leg shape in embodiment of illustration, as long as it can attach to a to-be-attached member, another shape attaching means may be sufficient. For example, when a stud bolt is fixed to a panel as a member to be attached, it may be an attaching means for locking to the stud bolt, and when a T stud with a button head is fixed to the panel, It may be an attaching means for locking to the T stud.

  A connection for connecting the first arm 5 and the second arm 6 to each free end of the first arm 5 and the second arm 6 which are pivotably connected by a hinge 7 so as to form a ring with both arms. Means are provided. In the illustrated embodiment, the connecting means of the second arm 6 is an elongated lock claw 10, and the connecting means of the first arm 5 receives the lock claw 10 and engages the locking claw (14 </ b> A or 14 </ b> B) of the lock claw 10. It is the lock receiving part 13 which has the latching shoulder 11 latched to. The lock claw 10 is formed with at least two locking claws 14A and 14B which are separated in the longitudinal direction. The lock claw 10 is inserted into the lock receiving portion 13 and any of the at least two locking claws 14A and 14B is formed. When the hook is locked to the locking shoulder 11 of the lock receiving portion 13, the first arm 5 and the second arm 6 are connected so as to form a ring, and at least one of the two locking claws (14A) is locked. The size of the ring is different between the case where it is locked to the shoulder 11 and the case where the other of the at least two locking claws (14B) is locked to the locking shoulder 11 (see FIGS. 6 and 7). The number of locking claws of the lock claw 10 is arbitrary as long as it is two or more, and may be three or four, for example. Further, the lock receiving portion 13 elastically presses the lock claw 10 to the side facing the engagement shoulder 11 in order to securely engage the engagement claws 14A and 14B of the received lock claw 10 with the engagement shoulder 11. An elastic support piece 15 is provided.

  The first arm 5 and the second arm 6 are formed with folded elastic holding pieces that elastically hold the wire harness inside the ring. In the first arm 5, the first elastic piece 17 is connected to the free ends of the first elastic piece 17 and the first elastic piece 17 extending along the first arm 5 from the connecting portion adjacent to the base of the lock receiving portion 13. A second elastic piece 18 that is folded back and extends along the line 17 is formed. In the second arm 6, the first elastic piece is connected to the free ends of the first elastic piece 17 </ b> A and the first elastic piece 17 </ b> A extending along the second arm 6 from the connecting portion where the attachment portion 9 is provided. A second elastic piece 18A extending back and extending along 17A is formed. The elastic holding piece composed of the first elastic piece and the second elastic piece may be one of the first arm 5 or the second arm 6, but in the illustrated embodiment, it is provided on both arms, thereby The wire harness can be held over a wider range with respect to the difference in holding force of the wire harness and the diameter of the wire harness. In the illustrated embodiment, the second elastic piece 18 (18A) is formed with a plurality of projections 19 spaced in the longitudinal direction on the surface facing the wire harness (the surface facing inward). As a result, the force that prevents the held wire harness from rotating about the axis is increased.

  Furthermore, the first elastic piece 17 (17A) and the second elastic piece 18 (18A) are preferably formed so as to elastically hold the wire harness with a specific elastic force. That is, the first elastic piece 17 is formed so as to generate a reaction force in the direction of turning to the second arm 6 around the connecting portion with the first arm 5 when pressed to the first arm 5 side. The second elastic piece 18 is formed such that when it is pressed toward the first elastic piece 17 side, a reaction force is generated in a direction of turning to the second arm 6 side around the connecting portion with the first elastic piece 17. The first elastic piece 17 and the second elastic piece 18 are formed so that a reaction force obtained by combining two reaction forces is directed toward the center of the ring. The relationship between the elastic forces of the first elastic piece 17 and the second elastic piece 18 of the first arm 5 is the same in the relationship between the first elastic piece 17A and the second elastic piece 18A of the second arm 6. . Further, as shown in FIG. 1, the first folded shape formed by the first elastic piece 17 and the second elastic piece 18 of the first arm 5, the first elastic piece 17A of the second arm 6 and the second elastic piece 17A. The second folded shape formed by the elastic piece 18A is symmetrical about the axis in the ring formed by the first arm 5 and the second arm 6 (or point symmetric about the axis). Is formed. By these, the force with which the elastic holding pieces (17, 18, 17A, 18A) hold the wire harness is maintained high, and it is possible to cope with a wider range of differences in the diameter of the wire harness.

  Further, the first arm 5 is provided with an engaging claw 14A or 14B of the lock claw 10 by bringing the lock receiving part 13 close to the lock claw 10 of the second arm at an end adjacent to the lock receiving part 13 which is a connecting means. A finger hook portion 20 is formed to assist in locking the locking shoulder 11. It is preferable that the shape of the finger-hanging portion 20 be a shape that facilitates the release of connection when the held long member is removed. Further, a pair of harness entry preventing pieces 21 extending toward the center of the hinge 7 so as to cover the hinge 7 is formed in a portion adjacent to the hinge 7 of the first arm 5 and a portion adjacent to the hinge 7 of the second arm 6. Is formed. The harness entry preventing piece 21 prevents the wire harness from coming into contact with the thin hinge 7 and prevents the hinge 7 from being broken by the wire harness.

  An operation of attaching the wire harness 3 as the long member to the panel 2 as the attached member using the clip 1 having the above configuration will be described with reference to FIGS. In FIG. 2, the clip 1 is in an open state in which the first arm 5 is not connected to the second arm 6. The attachment portion 9 of the clip 1 is inserted into the attachment hole 22 of the panel 2. As a result, the clip 1 is attached to the panel 2. In FIG. 3, the wire harness 2 is accommodated inside the arms 5 and 6 from the open portion of the first arm 5 and the second arm 6 in the open state in the clip 1 attached to the panel 2. Then, a part of the peripheral surface is arranged so as to contact the second elastic piece 18A of the second arm 6. Next, as shown in FIG. 4, when an operator applies a force as indicated by an arrow 23 by placing a finger on the finger-holding portion 20 of the first arm 5, the first arm 5 moves around the hinge 7 to the second arm. Then, the lock receiving portion 13 is pushed in so as to receive the lock claw 10 (see the broken arrow 25).

  By the above pushing, as shown in FIG. 5, the second elastic piece 18 and the first elastic piece 17 that are in contact with a part of the peripheral surface of the wire harness 3 are pressed and deformed toward the first arm 5, The reaction force accompanying this deformation is applied to the wire harness 3, and the wire harness 3 receiving the reaction force presses the second elastic piece 18A of the second arm 6 and further directs the first elastic piece 17A toward the second arm. Is pressed and deformed to generate a reaction force. By these reaction forces, the wire harness 3 is held with a high support force in the ring formed by the first arm 5 and the second arm 6. In addition, the lock receiving portion 13 that has received the lock claw 10 has its engagement shoulder 11 engaged with the engagement claw 14 </ b> A or 14 </ b> B of the lock claw 10, and the ring formed by the first arm 5 and the second arm 6. Keep it as it is. When the locking claw 14A is locked to the locking shoulder 11, it is a large-diameter wire harness, and when the locking claw 14B is locked to the locking shoulder 11, it is a small-diameter wire harness. Even if the locking shoulder 11 and the locking claw 14A or 14B try to move in the direction in which the locking is released due to the vibration of the clip 1 or the wire harness 3, the elastic supporting piece 15 of the lock receiving portion 13 engages with the locking shoulder 11. Locking with the pawl 14A (or 14B) is reliably maintained. In this way, the wire harness 3 is attached to the panel 3 by the clip 1. When the wire harness 3 is to be removed, in the state shown in FIG. 5, if the finger hooking portion 20 is pushed in the direction opposite to the direction of connection (arrow 26), the locking shoulder 11 and the locking claws 14 </ b> A (or 14 </ b> B) The lock is released, the connection can be released as shown in FIG. 4, and the wire harness 3 can be removed.

  With reference to FIG. 6 and FIG. 7, a state in which the clip 1 holds the large-diameter wire harness 3 </ b> A and the small-diameter wire harness 3 </ b> B will be described. In FIG. 6, a large-diameter wire harness 3 </ b> A is held by the clip 1. In this case, the locking claw 14A on the distal end side of the lock claw 10 is locked to the locking shoulder 11 of the lock receiving portion 13 to form a large ring formed by the first arm 5 and the second arm 6. . In addition, the first elastic piece 17 and the second elastic piece 18 of the first arm 5 are greatly deformed, and the first elastic piece 17A and the second elastic piece 18A of the second arm 6 are also greatly deformed, so that a large-diameter wire harness is formed. 3A is accommodated without difficulty and securely held.

  In FIG. 7, a small-diameter wire harness 3 </ b> B is held by the clip 1. In this case, not the locking claw 14A on the distal end side of the lock claw 10 but the second locking claw 14B is locked to the locking shoulder 11 of the lock receiving portion 13, and the first arm 5 and the second arm 6 are locked. The ring formed by is formed small. Further, the deformation of the first elastic piece 17 and the second elastic piece 18 of the first arm 5 is reduced, and the deformation of the first elastic piece 17A and the second elastic piece 18A of the second arm 6 is also reduced. Even if the deformation of the first elastic piece 17 (17A) and the second elastic piece 18 (18A) is small, the ring formed by the first arm 5 and the second arm 6 is formed small. The harness 3B is accommodated and securely held with a sufficient holding force.

  As described above, the size of the ring formed by connecting the first arm 5 and the second arm 6 is changed, and the first elastic piece and the second elastic piece inside the first arm 5 and the second arm 6 are changed. Since sufficient holding force is generated, it is possible to hold wire harnesses (elongate members) having various diameters.
