  The present invention relates to a clip that is coupled to a through-hole formed in a member. The clip is used for a purpose of fastening a plurality of members formed with through holes to each other, a purpose of closing the through holes, a purpose of coupling other members to the members formed with the through holes, and the like.

  There is a coupling structure in which a through-hole is formed in a plate-shaped member, a clip having a shaft portion is inserted into the through-hole, and the clip is rotated around an axis to couple the clip to the plate-shaped member. The clip has a head portion that also serves as a gripping portion that protrudes radially outward from the proximal end of the shaft portion, and a locking projection that protrudes radially outward from the distal end of the shaft portion. The through hole has a circular hole portion through which the shaft portion can pass and a concave groove that is recessed radially outward from the periphery of the circular hole portion and through which the locking convex portion can pass. The clip has a circular hole between the head and the locking projection by the shaft protruding around the axis after the locking projection passes through the groove and the shaft rotating around the axis. The peripheral edge of the part is held to prevent it from coming off from the through hole. Using such a coupling structure, different plate-like members are stacked on each other, coaxial through-holes and concave grooves are provided in mutually facing portions, and are integrally fastened by clips (for example, Patent Document 1).

  Clips such as those described above have access to the head of the clip for the rotation of the clip, and the work space for performing the rotation is compared with the axial direction of the coupling hole and the periphery around that axis. It needs to be large. Therefore, for example, when there is a wall portion extending in the axial direction of the coupling hole around the coupling hole, the wall portion may be an obstacle to fingers, and it may be difficult to grip and rotate the head. .

  The present invention has been made in view of the above background, and an object of the present invention is to reduce the space required for the mounting operation in the clip coupled to the hole.

  In order to solve the above problems, the present invention provides a clip (1) coupled to a coupling hole (33) formed in a member (31, 32), wherein the central axis (A) is the axis of the coupling hole. A body portion (2) that is inserted into the coupling hole so as to be substantially perpendicular to the coupling hole and is rotatable between a first rotational position and a second rotational position around the central axis in the coupling hole; The main body is loosely fitted into the coupling hole at the first rotation position and is sandwiched between the hole walls of the coupling hole at the second rotation position by rotation about the central axis. It has the outer surface part (3, 4) from which a distance with a hole wall changes, It is characterized by the above-mentioned.

  According to this configuration, the clip is coupled to the coupling hole by rotating around the central axis arranged substantially perpendicular to the axis of the coupling hole. When the clip is rotated around the central axis arranged substantially perpendicular to the axis of the coupling hole, the clip can be rotated by pushing a part of the clip toward the coupling hole from the axial direction of the coupling hole. . Therefore, even when only a relatively small space can be secured around the coupling hole, the clip can be easily coupled to the coupling hole.

  In the above invention, it is preferable that the main body is sandwiched between the hole walls of the coupling hole in a direction orthogonal to the central axis at the second rotational position. In the above invention, the main body has a first length (L1) in a first direction orthogonal to the central axis, is orthogonal to the central axis, and has a predetermined length from the first direction. When having a second length (L2) in a second direction having an angle and being in the first rotation position, facing the hole wall in the first direction and being in the second rotation position, The second direction is preferably opposed to the hole wall in the second direction, and the second length is larger than the first length.

  According to this configuration, the clip can be sandwiched and coupled to the coupling hole by the rotation operation of the clip.

  Further, in the above invention, the main body has a third length (L3) in a third direction perpendicular to the central axis and existing between the first direction and the second direction, The third length is preferably larger than the second length.

  According to this configuration, once the clip is rotated to the second rotation position, the clip is maintained at the second rotation position, and the coupling state between the clip and the coupling hole is stably maintained.

  In the above invention, the first direction and the second direction may be substantially orthogonal to each other. Further, in the above invention, the main body part is formed in a substantially parallelogram in a cross section orthogonal to the central axis, and the first direction has a pair of longer sides of the substantially parallelogram in the cross section. The second direction coincides with a direction in which a pair of shorter sides of the substantially parallelogram of the cross section faces each other, and the third direction corresponds to a pair of substantially rectangular shapes of the cross section. The diagonals may coincide with the directions facing each other.

  Moreover, in the said invention, it is preferable that the corner | angular part arrange | positioned in the said 3rd direction of the said main-body part is chamfered.

  According to this configuration, the catch between the clip and the hole wall of the coupling hole is reduced, and the rotation operation is facilitated.

  According to the above configuration, the space required for the mounting work can be reduced in the clip coupled to the hole.

The locking projection 9 is formed in a substantially rectangular parallelepiped and extends in the first direction.

  As shown in FIG. 1, a concave groove 11 extending in the first direction is formed on the upper surface of the main body 2. The wall portion and the bottom portion of the groove 11 are formed in a curved surface centering on an axis extending in the first direction, and both ends thereof are continuous with the outer surface of the long side wall portion 3.

The upper edge portion 13 of each short side wall portion 4 constitutes the upper end edge of the main body portion 2, is continuous with the upper end of the inclined edge portion 12, and extends in parallel with the first direction.

  The pair of locking pieces 5 extend from the boundary portion between the long side wall portion 3 and the short side wall portion 4 so as to incline in the second direction and upward. Thereby, as shown in FIG. 3, the main-body part 2 and a pair of locking piece 5 are cooperating, and exhibit V shape seeing from a 1st direction. As shown in FIG. 1, the locking piece 5 includes a first side surface 16 that is flush with the outer surface of the long side wall portion 3 at a portion that faces in the left-right direction, and a first side surface 16 that is opposite to the first side surface 16. And a second side surface 17 orthogonal to the short side wall portion 4. Further, the locking piece 5 is provided between the first side surface 16 and the second side surface 17 on the side opposite to the upper side inclined surface 18 and the upper side inclined surface 18 smoothly connected to the curved surface of the concave groove 11, A lower inclined surface 19 extending in parallel with the upper inclined surface 18 from the bottom wall portion 8 to the distal end side is provided.

The escape groove 21 is provided for the purpose of facilitating the deformation of the short side wall portion 4.

  The clip 1 configured as described above has a 180 ° rotationally symmetric shape about the central axis A.

  Next, a usage example of the clip 1 will be described. The clip 1 is coupled to a coupling hole 33 formed by the first member 31 and the second member 32 in cooperation, and fastens the first member 31 and the second member 32 together. As shown in FIG. 5, the first member 31 has a planar coupling surface 36 on which a striker 35 is projected. The striker 35 includes a pair of side columns 37 that are vertically spaced from each other and perpendicular to the coupling surface 36, and a beam 38 that connects the ends of the pair of side columns 37. Each of the pair of side columns 37 and beams 38 has a square cross section. The striker 35 forms an inner hole having a rectangular cross section by the cooperation of the pair of side columns 37, the beam 38, and the coupling surface 36. The second member 32 has a flat plate portion 42 having an insertion hole 41 penetrating in the thickness direction. The first member 31 and the second member 32 are resin molded bodies in the present embodiment, and have flexibility. In other embodiments, the first member 31 and the second member 32 may be made of metal.

  As shown in FIG. 6, when the striker 35 passes through the insertion hole 41, the flat plate portion 42 of the second member 32 is placed on the coupling surface 36 of the first member 31. The insertion hole 41 is a long hole having a rectangular cross section, and each side column 37 is fitted into both ends of the long hole. When the striker 35 is fitted into the insertion hole 41, the flat plate portion 42 is supported so as not to move in the surface extending direction with respect to the coupling surface 36. In this state, the coupling hole 33 is defined by the striker 35 that has passed through the insertion hole 41. That is, the coupling hole 33 which is a through hole is formed by the cooperation of the distal ends of the pair of side columns 37, the beam 38, and the peripheral edge of the insertion hole 41. The axis of the coupling hole 33 extends in parallel with the coupling surface 36.

  In addition, the base end portion of the pair of side columns 37, the hole wall of the insertion hole 41, and the coupling surface 36 cooperate to form a locking recess 44 that is a bottomed hole continuous to the coupling hole 33. . The locking recess 44 is formed in the hole wall of the coupling hole 33 so that its axis is orthogonal to the axis of the coupling hole 33. The coupling hole 33 formed as described above has a rectangular cross section, and has a first width W1 (distance between both side columns 37) and a second width W2 (the upper surface of the flat plate portion 42 and the lower surface of the beam 38). ) And depth (hole length) D. The coupling hole 33 and the clip 1 are configured to satisfy the relationships of L1 <W1 ≦ L2, L4 <W2 ≦ L5 <L6, and D <L1 <L2. Note that W1 is preferably set to be slightly larger than L1 and slightly smaller than L2. Further, W2 is preferably set to be slightly smaller than L5.

  With the striker 35 inserted into the insertion hole 41 and the first member 31 and the second member 32 being combined to form the coupling hole 33, the clip 1 is inserted into the coupling hole 33 and the clip 1 is coupled to the coupling hole 33. . For convenience of explanation, the direction in which the axis of the coupling hole 33 extends is defined as the front-rear direction, and the direction in which the side pillars 37 are separated is defined as the left-right direction. As shown in FIG. 6, the clip 1 is disposed so that one of the pair of short side wall portions 4 faces the coupling hole 33, and is inserted into the coupling hole 33 from the tip of the one locking piece 5. At this time, the clip 1 has a length L1 in the left-right direction, which is smaller than the first width W1 of the coupling hole 33, but has a length L6 in the vertical direction, and the second of the coupling hole 33. It becomes larger than the width W2. Therefore, the clip 1 is moved along the arc locus (see the broken arrow in FIG. 6) to avoid interference between the locking piece 5 and the hole wall of the coupling hole 33. Specifically, the clip 1 is first arranged so that the front end of the locking piece 5 faces the coupling hole 33 and the extending direction of the locking piece 5 is substantially parallel to the axis of the coupling hole 33. FIG. As shown, the clip 1 is rotated with respect to the coupling hole 33 so that the distal end of the locking piece 5 moves upward on the back side of the coupling hole 33 while the locking piece 5 is inserted into the coupling hole 33 from the distal end. At this time, the concave groove 11 secures a gap between the main body 2 and the hole wall (beam 38) of the coupling hole 33 so that the clip 1 can be inserted along the arc locus.

  As shown in FIGS. 8 to 10, when the clip 1 is inserted into the coupling hole 33, one locking piece 5 passes through the coupling hole 33 and is disposed in front of the striker 35. The part enters the inside of the coupling hole 33, and the concave groove 11 and the beam 38 forming a part of the hole wall of the coupling hole 33 face each other. At this time, the locking convex portion 9 of the clip 1 enters the locking concave portion 44, and the front end portion and the rear end portion of the bottom wall portion 8 of the main body portion 2 are arranged on the flat plate portion 42 arranged before and after the locking concave portion 44. Surface contact is possible on the top surface. This state is called a temporarily fixed state. In the temporarily fixed state, the center axis A of the clip 1 extends in the vertical direction and is orthogonal to the axis of the coupling hole 33. The rotation position of the clip 1 around the central axis A in the temporarily fixed state is defined as a first rotation position. In the first rotation position, the front end and the rear end of the main body portion 2 project outside the coupling hole 33, the pair of upper edge portions 13 are disposed outside the coupling hole 33, and the hole wall (beam 38) of the coupling hole 33. It is away from.

  In the temporarily fixed state, when the upper inclined surface 18 of the pair of locking pieces 5 hits the peripheral edge portion (beam 38) of the coupling hole 33, or the locking convex portion 9 hits the wall surface of the locking concave portion 44. The back-and-forth movement with respect to one coupling hole 33 is restricted to a predetermined range. Further, when the long side wall portions 3 of the clip 1 abut against the hole walls (both side pillars 37) of the coupling hole 33, the left-right movement of the clip 1 with respect to the coupling hole 33 is restricted within a predetermined range. Further, when the wall surface of the concave groove 11 abuts against the hole wall (beam 38) of the coupling hole 33 or the bottom wall portion 8 abuts against the flat plate portion 42 of the second member 32, the clip 1 moves up and down with respect to the coupling hole 33. Is regulated within a predetermined range. As described above, the clip 1 is loosely fitted in the coupling hole 33 in the front-rear direction, the left-right direction, and the vertical direction. In order to detach the clip 1 from the coupling hole 33 in the temporarily fixed state, it is necessary to move the clip 1 along an arc locus as in the insertion.

  Next, the clip 1 is rotated clockwise around the central axis A from the first rotation position (based on the state viewed from above). At this time, when the locking projection 9 abuts against the hole wall of the locking recess 44, the back-and-forth movement of the clip 1 with respect to the coupling hole 33 is suppressed within a predetermined range. The rotation is performed up to a position (referred to as a second rotation position) that is regulated by the second side surface 17 of each locking piece 5 striking against both side pillars 37 that are the hole walls of the coupling hole 33. This state after rotation is called a coupled state. As shown in FIGS. 11 to 14, in the second rotational position, the clip 1 is in a state in which both short side wall portions 4 are disposed in the coupling hole 33, that is, the second direction is parallel to the left-right direction. It will be in an arranged state. The clip 1 has a length L2 in the second direction, and is larger than the first width W1 of the coupling hole 33. Therefore, in the second rotation position, at least one of the clip 1 and the hole wall of the coupling hole 33 is elastically deformed, the pair of short side wall portions 4 of the clip 1 abuts on the hole wall of the coupling hole 33, and the clip 1 is coupled. It is clamped from the left-right direction by the hole wall of the hole 33. As a result, the clip 1 is coupled to the coupling hole 33 without rattling in the left-right direction.

  Further, the clip 1 rotates from the first rotation position to the second rotation position, whereby the upper edge portion 13 is disposed in the coupling hole 33. The clip 1 has a length L5 in the vertical direction at the portion where the upper edge portion 13 is located, and the length is equal to or greater than the second width W2 of the coupling hole 33. Therefore, at least one of the hole walls (mainly the side pillars 37 and the beams 38) of the clip 1 and the coupling hole 33 is elastically deformed, and the upper edge portion 13 and the bottom wall portion 8 of the clip 1 are in contact with the hole wall of the coupling hole 33. In contact therewith, the clip 1 is sandwiched by the hole wall of the coupling hole 33 from the vertical direction (direction along the central axis A). As a result, the clip 1 is coupled to the coupling hole 33 without rattling in the vertical direction.

  Further, when the clip 1 rotates from the first rotation position to the second rotation position, one of the pair of locking pieces 5 is disposed on the front side of the hole edge (beam 38) of the coupling hole 33, and the other is the coupling hole. It is arranged on the rear side of 33 hole walls (beam 38). As a result, the clip 1 is restricted from moving in the front-rear direction with respect to the coupling hole 33 when the locking piece 5 abuts against the hole wall (beam 38) of the coupling hole 33 from the front and rear. Further, as described above, since the clip 1 is in contact with the hole wall of the coupling hole 33 at the pair of the short side wall portion 4, the upper edge portion 13 and the bottom wall portion 8, the frictional force acting on these contact portions. Thus, the back and forth movement of the clip 1 with respect to the coupling hole 33 is restricted. Note that the pair of locking pieces 5 may be configured to simultaneously contact the edge of the coupling hole 33. Further, at the second rotational position, the locking projection 9 extends in the front-rear direction and is sandwiched from the front and rear by the locking recess 44. At this time, it is preferable that at least one of the locking projection 9 and the locking recess 44 is elastically deformed and pressed against each other. Thereby, the back-and-forth movement of the clip 1 with respect to the coupling hole 33 is restricted.

  In the process of rotating from the first rotation position to the second rotation position, the clip 1 passes through the pair of curved surface portions 6 entering the coupling hole 33. Since the length L3 between the pair of curved surface portions 6 is larger than the first width W1 of the coupling hole 33, elastic deformation of at least one of the main body portion 2 and the hole wall of the coupling hole 33 is required during rotation. Since the length L3 between the pair of curved surface portions 6 is longer than both L1 and L2, the clip 1 does not rotate spontaneously between the first rotation position and the second rotation position. That is, the clip 1 rotates when a rotational force of a predetermined value or more is applied. For this reason, the clip 1 is maintained in the second rotational position after being in the coupled state, and maintains the coupling with the coupling hole 33.

  The clip 1 according to the present embodiment can be coupled to the coupling hole 33 by a simple operation of being inserted into the coupling hole 33 and rotated about the central axis A that is substantially perpendicular to the axis of the coupling hole 33. The rotation operation of the clip 1 can be performed only by pushing a part of the clip 1 (for example, the locking piece 5) into the side pillar 37 side of the striker 35, and the work space required for the rotation operation is reduced. In this embodiment, the clip 1 is inseparable from each other, that is, the first member 31 and the second member 32 can be separated from each other by coupling to the coupling hole 33 formed by combining the first member 31 and the second member 32. Keep it connected. Since the clip 1 has a simple configuration and can be coupled to the coupling hole 33 which is a through hole, the clip 1 is highly versatile.

(Second Embodiment)
Next, the clip 50 according to the second embodiment will be described with reference to FIGS. The clip 50 according to the second embodiment is different from the clip 1 according to the first embodiment only in that it does not have the locking projection 9, and the other configurations are the same. In the clip 50 according to the second embodiment, the same components as those of the clip 1 according to the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  The clip 50 is coupled to a coupling hole 53 formed by the cooperation of the first member 51 and the second member 52, and fastens the first member 51 and the second member 52 together. The first member 51 and the second member 52 have plate-like portions 55 and 56 stacked on each other, and have through-holes 57 and 58 having the same shape at positions corresponding to each other of the plate-like portions 55 and 56. Each through-hole 57, 58 penetrates each plate-like portion in the thickness direction and has a rectangular cross section. The through holes 57 and 58 face each other and communicate with each other to form one continuous coupling hole 53 having a first width W1, a second width W2, and a depth D. The dimensional relationship among the first width W1, the second width W2, and the depth D is the same as that of the coupling hole 33 according to the first embodiment.

  As shown in FIG. 15, the clip 50 according to the second embodiment, like the clip 1 according to the first embodiment, has an arc locus in order to avoid contact between the locking piece 5 and the peripheral edge of the coupling hole 53. Is inserted into the coupling hole 53 so as to be in a temporarily fixed state shown in FIG. In this state, the pair of locking pieces 5 abut against the first member 51 or the second member 52 from the front-rear direction, thereby preventing the clip 1 from coming off from the coupling hole 53. Then, by rotating clockwise around the central axis A from the temporarily fixed state, the clip 1 is in a coupled state and coupled to the coupling hole 53 as shown in FIG. In the coupled state, the clip 1 is omitted from the clip 1 according to the first embodiment in the coupling structure of the locking projection 9 and the locking recess 44, but the pair of short side walls 4 and the bottom wall Due to the frictional force between the portion 8 and the upper edge portion 13 and the hole wall of the coupling hole 53 and the contact between the pair of locking pieces 5 and the first member 51 and the second member 52, the clip 1 is coupled to the coupling hole 53. Back and forth movement is regulated.

  Thus, the clip 50 can be coupled to the coupling hole 33 even if the coupling structure by the latching convex portion 9 and the latching concave portion 44 is omitted. In the second embodiment, the coupling hole 53 is formed using the two members of the first member 51 and the second member 52. However, the coupling hole may be formed by forming a through hole in one flat plate.

(Third embodiment)
Next, the clip 60 according to the third embodiment will be described with reference to FIGS. The clip 60 according to the third embodiment is different from the clip 1 according to the first embodiment in that it does not have the locking protrusion 9 and the groove 11 and the shape of the locking piece 63 is different. Other configurations are the same. In the clip 60 according to the third embodiment, the same components as those of the clip 1 according to the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  As shown in FIG. 18, the main body 2 of the clip 60 is formed in a substantially rectangular cross section perpendicular to the central axis A, like the clip 1, and has a pair of long side walls 3 and a pair of short side walls 4, It has a bottom wall portion 8 and an upper wall portion 61. The upper wall portion 61 is formed in parallel with the bottom wall portion 8.

  The pair of locking pieces 63 extend from the boundary between the long side wall 3 and the short side wall 4 along the second direction. That is, the locking piece 63 is disposed between the upper wall portion 61 and the bottom wall portion 8 in the vertical direction. Thereby, when it sees from a 1st direction, the main-body part 2 and a pair of latching piece 63 are extended in linear form. The locking piece 63 is provided in parallel with the first side surface 65 on the side opposite to the first side surface 65 on the side facing the outer surface of the long side wall portion 3 on the portion facing the left and right direction, and on the side opposite to the first side surface 65. It has the 2nd side surface 66 orthogonal to the side wall part 4. As shown in FIG.

  The clip 60 is coupled to a coupling hole 72 formed in the flat plate member 71. The coupling hole 72 has a rectangular cross section, and has a first width W1, a second width W2, and a depth D. The dimensional relationship among the first width W1, the second width W2, and the depth D is the same as that of the coupling hole 33 according to the first embodiment. Further, when the length in the vertical direction of the main body 2 (the distance between the upper wall 61 and the bottom wall 8) is L7, the length L7 is L7 ≦ W2.

  The clip 60 is arranged so that one short side wall 4 faces the coupling hole 72 and is inserted into the coupling hole 72 from the tip of one locking piece 63 along the axial direction of the coupling hole 72. As shown in FIG. 19, the clip 60 is inserted until the center axis A is disposed at the center of the coupling hole 72, and is temporarily fixed. As in the first and second embodiments, the clip 60 is coupled clockwise as shown in FIG. 20 by rotating the clip 60 clockwise from the first rotation position to the second rotation position about the central axis A from the temporarily fixed state. It becomes a state. In the coupled state, at least one of the clip 60 and the coupling hole 72 is elastically deformed, the pair of short side wall portions 4 and the hole walls of the coupling hole 72 are pressed against each other, and the clip 60 is sandwiched by the coupling hole 72 from the left-right direction. Further, the clip 60 is restricted from moving in the front-rear direction by one of the locking pieces 63 abutting against the front surface of the member 71 and the other abutting against the rear surface of the member 71. Similarly to the first and second embodiments, the clip 60 has a length L3 between the curved surface portions that is longer than L1 and L2, and therefore does not spontaneously rotate from the second rotational position to the first rotational position. In addition, the coupling state with the coupling hole 72 can be stably maintained.

  The clip 60 preferably has a length L7 in the vertical direction slightly smaller than the second width W2 of the coupling hole 72 so that the coupling hole 72 can be sealed without gaps in the vertical direction. The clip 60 can be used as an anchor for connecting another member to the member 71 or a hole plug for closing the connecting hole 72. When used as an anchor, other members may be coupled to the clip 60 in advance so as not to hinder the rotation of the clip 60 relative to the coupling hole 72. Moreover, you may use the clip 60 as a fastener which fastens a some member like 2nd Embodiment.

  Although the description of the specific embodiment is finished as described above, the present invention is not limited to the above embodiment and can be widely modified. For example, in the above-described embodiment, the example in which the cross-sectional shape of the coupling hole is rectangular has been described, but the cross-sectional shape may be other shapes such as a polygon, an ellipse, and a circle. In this case, what is necessary is just to determine the shape of the main-body part of a clip according to the shape of a joint hole. In the present embodiment, the cross-sectional shape orthogonal to the central axis A of the main body 2 is substantially rectangular (the shape in which the long side wall 3 and the short side wall 4 are orthogonal), but the cross-sectional shape of the main body 2 is L2. Since it may be a shape satisfying the relationship of> L1, it may be a parallelogram, an ellipse, or the like.
