  In the conventional pantograph-type clip described in Patent Document 1, when the head is pulled toward the shaft, the head may pull the connecting portion with the second arm toward the shaft. Rather than holding the mounting member in a state where the arm overlaps the first arm, the holding member is recessed (inverted) into the mounting hole of the mounting member, so that the holding of the mounting member may be impaired. there were.

  The clip described in Patent Document 2 is not a pantograph-type clip, but a flange, a shaft portion extending from the flange, a pair of pressing pieces hinged to the tip of the shaft portion, and a state in which the pressing pieces project outward in the radial direction. It consists of the head to hold | maintain, and consists of a structure attached to a mounting member with a flange and a pair of pressing piece. Also in the case of this clip, when the head is pulled toward the shaft, the head may pull the connecting part with the holding piece toward the shaft, and the holding piece protrudes radially outward From there, there is a risk that the holding of the mounting member may be impaired due to being tilted inward (that is, inverted) so as to enter the mounting hole of the mounting member.

  The clip described in Patent Document 3 is not a pantograph-type clip, and is different from the clip described in Patent Document 2. This clip is composed of a flange, a shaft portion extending from the flange, and a pair of elastic pressing pieces formed to be inclined toward the flange side while projecting radially outward at the tip of the shaft portion. The pressing piece and the shaft portion are pushed in, the flange is brought into contact with one surface of the mounting member, the pressing piece is brought out on the other surface of the mounting member, and the surface is pressed to be attached to the mounting member. Further, the clip is provided with a reversal prevention protrusion for preventing the pressing piece from reversing at the tip of the shaft portion, so that the pressing piece does not reverse even if the pressing piece is pulled into the shaft side. . This clip is not a pantograph-type clip, and the holding piece is not hinged to the shaft portion. Therefore, the configuration for preventing the inversion of the pantograph type clip in which the first arm and the second arm are hinge-connected is not shown. The slip stopper described in Patent Document 4 is completely different from the pantograph type clip in structure, and is composed of a first ring part and a second ring part, and the clip that holds the mounting member from both sides with both ring parts. It is. This clip has a plurality of protrusions that engage with the mounting member on the surface that presses the mounting member.

  An object of the present invention is to prevent a head of a pantograph-type clip from being pulled toward a shaft portion and the second arm from entering the mounting hole of the mounting member in a reverse state due to the pulling of the head. It is in.

  In order to achieve such an object, according to the present invention, a shaft portion that is inserted into a mounting hole of a mounting member such as an insulator, a flange that is provided at one end of the shaft portion and holds one surface of the mounting member, and a shaft A pair of first arms provided on the other end side of the portion and extending so as to extend the shaft portion when extended, and connected to the first arm so as to extend from the first arm via a hinge, together with the first arm It consists of a pair of second arms forming a pantograph shape, and a head connected to each of the ends of the pair of second arms, and the first arm and the second arm project outwardly about the hinge. Are folded and overlapped with each other to hold the other surface of the mounting member. When the head is pressed against the shaft, the first arm and the second arm move around the hinge. Locking to keep folded and overlapping each other The clip is provided with a step, and the head is pulled toward the shaft when the first arm and the second arm are folded around the hinge and overlapped with each other. There is also provided a clip characterized in that a stopper is formed which contacts the second arm and prevents the head from being pulled.

  With the above clip, the stopper of the head of the pantograph type clip abuts against the second arm to prevent the head from being pulled in, so that the second arm is not pulled in so as to be submerged by the head. It is possible to prevent the arm from entering the mounting hole of the mounting member in a reversed state.

  In the clip, the stopper is formed in a shape that holds the second arm together with the first arm toward the flange when the first arm and the second arm are folded around the hinge and overlap each other. In one embodiment, the stopper is a triangular rib that is provided at a position adjacent to the second arm on the side surface of the head and has a wide shape from the top surface of the head toward the second arm. The flange has a projection that engages with the mounting member on the surface facing the mounting member. When the stopper presses against the flange, the projection bites into the mounting member, and the clip rotates around the mounting hole. Can be prevented, and can be prevented from coming off due to displacement when the mounting hole is a long hole. The flange and the shaft part are formed with cavities for receiving rod-like studs formed with locking means such as threads or circumferential grooves. The inner wall surface of the shaft part cavity is associated with the stud locking means. A locking claw for stopping is formed. Thus, the clip can be used to attach the attachment member to the attached member.

  A pantograph clip 1 according to an embodiment of the present invention will be described below with reference to the drawings. 1 to 3 show the clip 1 alone, FIGS. 4 to 7 show the operation of attaching the clip 1 to the attachment member 2, and FIGS. 8 and 9 show an insulator and a dashboard. The effect | action of the clip 1 attached to attachment members 2, such as a dash pad, is shown.

  The configuration of the clip 1 will be described with reference to FIGS. The clip 1 is integrally formed of hard plastic. 1 shows a front view of the pantograph-shaped clip 1 with the first arm 7 and the second arm 10 extended, and FIG. 2 shows the first arm 7 and the second arm 10 around the hinge 9. FIG. 3 shows a front view of the clip 1 in a state of being folded and overlapping each other, and FIG. 3 is a plan view of the clip 1 in the overlapping state of FIG. 1 to 3, a clip 1 is provided at a shaft portion 5 inserted into a mounting hole 3 of a mounting member 2 such as an insulator, and one end of the shaft portion 5 (lower end in FIGS. 1 and 2). 2 is provided on the other end side (upper end side in FIGS. 1 and 2) of the flange portion 6 that holds one surface (the lower surface of the mounting member 2 in FIGS. 4 to 7). A pair of first arms 7, 7 extending in a diametrical direction of the shaft portion 5, extending so as to extend the portion 5, and connected to the first arm 7 so as to extend from the first arm 7 via a hinge 9. The first arm 7 includes a pair of second arms 10 and 10 that form a pantograph shape, and a head 11 connected to each of the ends of the pair of second arms 10.

  When the clip 1 folds so that the first arm 7 and the second arm 10 project outwardly about the hinge 9 and overlap each other (see FIGS. 2 and 7), the other surface of the attachment member 2 ( The upper surface of the mounting member 2 in FIGS. 4 to 7 is held. The connecting portion 13 between the first arm 7 and the shaft portion 5 and the connecting portion 14 between the second arm 10 and the head portion 11 are thin portions so that the first arm 7 and the second arm 10 can overlap each other. Formed by a hinge.

  Further, in the clip 1, when the head 11 is pressed against the shaft 5, the first arm 7 and the second arm 10 are folded around the hinge 9 and overlap each other. In the illustrated embodiment in which a locking means for holding is provided, the shaft portion 5 is provided with a pair of locking portions 15 protruding toward the head portion 11, and the head portion 11 has a shaft A pair of locking claws 17 projecting toward the locking part 15 of the part 5 are provided. Therefore, as shown in FIG. 2, when the first arm 7 and the second arm 10 are folded around the hinge 9 and overlap each other, the locking portion 15 and the locking claw 17 are locked, The overlapping state is maintained.

  Further, the flange 6 and the shaft portion 5 are formed with cavities 18 and 19 for receiving rod-shaped studs (not shown) having locking means such as threads or circumferential grooves formed on the outer peripheral surface. On the inner wall surface 21 of the five cavities 19, a pair of locking claws 22 that are locked to the stud locking means are formed. Thus, the clip 1 is used to attach the attachment member 2 to a member to be attached (not shown).

  In the clip 1, even when the head 11 is pulled toward the shaft portion 5 when the first arm 7 and the second arm 10 are folded around the hinge 9 and overlap each other, A pair of stoppers 23 that are in contact with the two arms 10 and prevent the head 11 from being pulled in are formed in accordance with the second arm 10. The stopper 23 is formed in a shape that holds the second arm 10 together with the first arm 7 toward the flange 6 when the first arm 7 and the second arm 10 are folded around the hinge 9 and overlap each other. Has been. In the illustrated embodiment, the stopper 23 is provided at a position adjacent to the connecting portion 14 of the second arm 10 on the side surface 25 of the head 11, and is directed from the top surface side of the head 11 toward the second arm 10. It consists of triangular ribs with a wide shape that gradually protrudes in the radial direction. Accordingly, even when the head 11 is pulled toward the shaft portion 5 when the first arm 7 and the second arm 10 are folded around the hinge 9 and overlap each other, the stopper 23 remains in the second arm 10. The head portion 11 is reliably brought into contact with the portion of a certain length, the head 11 is reliably prevented from being pulled in, and the second arm 10 together with the first arm 7 is reliably pressed toward the flange 6.

  Even if the head 11 is strongly pulled toward the shaft portion 5 by the stopper 23, the second arm 10 is inverted in the mounting hole of the mounting member (in the radial direction so as to sink into the mounting hole of the mounting member). The state where the second arm 10 is brought into the mounting hole of the mounting member 2 can be prevented. Further, since the stopper 23 holds the second arm 10 together with the first arm 7 toward the flange 6, the clip 23 is securely clamped in cooperation with the flange 6, whereby the clip 1 is attached to the mounting member 2. Is held securely.

  In the clip 1, a protrusion 26 that engages with the attachment member 9 is formed on the flange 6 on the surface facing the attachment member 2. The position and number of the protrusions 26 are arbitrary, but in the illustrated embodiment, two protrusions 26 are provided at positions facing the first arms 7 corresponding to the pair of first arms 7. Since the stopper 23 presses the second arm 10 and the first arm 7 toward the flange 6, the protrusion 26 can surely bite into the mounting member 2 and prevent the clip 1 from rotating around the mounting hole. Even when the mounting hole 3 of the mounting member 2 is a long hole, the clip 1 does not shift in position, so that it is prevented from shifting to the long axis side of the long hole. Can be surely stopped.

  An operation procedure for attaching the clip 1 having such a configuration to the attached member 2 will be described with reference to FIGS. First, in FIG. 4, the clip 1 or the mounting member 2 is positioned so that the head 11 of the clip 1 in which the first arm 7 and the second arm 10 are extended passes through the mounting hole 3 of the mounting member 2 ( FIG. 4). After the positioning, the clip 1 or the mounting member 2 is pushed into the mounting hole 3 with the head 11, the second arm 10, the first arm 9 and the shaft portion 5 of the clip 1 as it is, and the flange 6 is mounted as shown in FIG. The lower surface of the member 2 is brought into contact with the lower surface. At this time, if the mounting member 2 is a member made of a soft material, the protrusion 26 bites into the mounting member 2. Next, as shown in FIG. 6, the head 11 is pushed in the direction of the arrow 27 to bring the locking claw 17 of the head 11 closer to the locking portion 15 of the shaft portion 5. At the end of the pushing, the first arm 7 and the second arm 10 are folded around the hinge 9 and overlap each other as shown in FIG. At this time, the locking claw 17 of the head 11 is locked by the locking portion 15 of the shaft portion 5, and the first arm 7 and the second arm 10 are folded around the hinge 9 and held in a mutually overlapping state. Is done. As a result, the clip 1 is attached to the attachment member 2.

  After the clip 1 is attached, a case where a force for the head portion 11 to be strongly pulled toward the shaft portion 5 acts as shown by an arrow 29 will be described with reference to FIG. When the first arm 7 and the second arm 10 are folded around the hinge 9 and overlap each other in the head 11, even if the head 11 is pulled toward the shaft 5, A stopper 23 is provided that contacts and prevents the head 11 from being pulled. Therefore, even if a strong force is applied to the head 11 in the direction of the arrow 29, the stopper 23 comes into strong contact with the second arm 10 and the second arm 10 is inverted in the mounting hole 3 of the mounting member 2 (the mounting member In a state of being tilted inward in the radial direction so as to sink into the mounting hole. This reliably prevents the second arm 10 from entering the mounting hole 3 of the mounting member 2.

  Further, since the stopper 23 holds the second arm 10 together with the first arm 7 toward the flange 6, the clip 23 is securely clamped in cooperation with the flange 6, whereby the clip 1 is attached to the mounting member 2. Is held securely. And by this strong clamping, the protrusion 26 formed in the flange 6 bites into the attachment member 2 as shown by an arrow 30 in FIG. In this state, even if a force for rotating the clip 1 in the mounting hole 3 acts as shown by an arrow 31 in FIG. As described above, since the clip 1 can be prevented from rotating around the axis of the mounting hole 3, even when the mounting hole 3 of the mounting member 2 is a long hole, the clip 1 is not displaced, and the clip The first arm 7 and the second arm 10 are prevented from shifting to the long axis side of the long hole, and therefore, the disconnection due to the positional deviation of the clip 1 can be reliably prevented.
