Description

  The present invention relates to a clip fixed to a mounting hole formed in, for example, a vehicle body panel of an automobile.

  For example, a mounting hole is formed in a body panel of an automobile, and a trim board or the like is attached to the body panel via a clip that is inserted and fixed thereto, or a window frame provided in the body panel Temporary fixing of glass or the like is performed.

  As a conventional clip of this type, the following Patent Document 1 includes a head and a leg, and the leg includes four legs that hang independently from the head.

Japanese Utility Model Publication No. 4-105615 JP 2005-315369 A

  The leg part in the clip of the above-mentioned Patent Document 1 is composed of four legs hanging from the head, and the leg center surrounded by the four legs is a gap, so the leg part is inserted into the hole. In doing so, the four legs are inserted while being deformed inwardly, and can be inserted with a relatively light force. On the other hand, when the unintentional strong pulling force or twisting force acts on the clip while the clip is locked in the hole, the four legs are bent relatively easily, and the clip is pulled out from the hole. There is a fear.

  On the other hand, the clip of Patent Document 2 has a column suspended from the center of the lower surface of the head, and has at least three protrusions radially extending from the column, so that the clip is attached to the mounting hole. Even if a strong pulling force or a twisting force is applied to the clip, the bending of the engagement piece provided between the three protrusions is suppressed, and the clip is held firmly against the mounting hole.

  However, the distal end portion (lower end portion) of each engagement piece is connected in an annular shape through a plurality of protrusions extending from the support column, so that the rigidity is high and the structure is difficult to bend. For this reason, when the leg portion is inserted in a state where the center is shifted with respect to the center of the mounting hole, the insertion resistance may be high and the insertion may be difficult.

  Further, the clip of Patent Document 2 has a plurality of engaging pieces extending along the circumferential direction from at least three protruding parts provided on the leg part. A plurality of gaps are provided along the axial direction of the legs. In order to mold this gap, a plurality of molds that can be removed along the axial direction of the leg portions are required. However, when the inner diameter of the mounting hole is small and the outer diameter of the leg portion is small, the gap is also narrowed, and a plurality of molds that form the gap must be extremely narrowed. Sometimes became a problem.

  Therefore, an object of the present invention is to insert the metal into the mounting hole smoothly with a relatively light force, to obtain a sufficient holding force with respect to the mounting hole, and to mold the internal shape of the leg portion. The object is to provide a clip capable of improving the durability of a mold.

  In order to achieve the above object, a first aspect of the present invention includes a head portion that engages with the front surface side of the mounting hole, and a leg portion that extends from the back surface side of the head portion and engages with the back surface side of the mounting hole. The leg portion is disposed at a predetermined position in the axial direction of the pair of shaft portions and a pair of shaft portions extending substantially in parallel from the back side of the head, and the pair of shaft portions. A connecting portion that connects the shaft portions in a ring shape, and a plurality of elastic pieces that are connected at one end to the shaft portion or the connecting portion and connected at the other end to the back surface of the head. A clip is provided in which an engaging portion that engages with the back surface side of the mounting hole is provided on the outer periphery.

  According to the above invention, when the leg portion is inserted into the mounting hole, the pair of shaft portions and the plurality of elastic pieces are pushed in while being bent inward. And when the engaging part of an elastic piece slips out to the back surface side of an attachment hole, it will be elastically restored and an engagement part will engage with the back surface side of an attachment hole. As a result, since the member to be attached is sandwiched between the head portion engaged with the front surface side of the attachment hole and the elastic piece engaged with the rear surface side, the clip can be fixed.

  In this clip, when inserting the leg portion into the mounting hole, not only the elastic engagement piece but also the pair of shaft portions to which the elastic piece is connected bend inward, so that the insertion resistance is reduced. It can be made relatively low, and the leg portion can be smoothly inserted into the mounting hole.

  In addition, since the pair of shaft portions are connected by an annular connecting portion disposed at a predetermined position in the axial direction and have an appropriate rigidity, unintended pulling force is applied to the clip attached to the mounting hole. Even if a twisting force is applied, these forces are received and a high holding force is obtained for the mounting hole.

  Furthermore, since the inside of the leg is a single continuous space, the shape of the inside of the leg can be molded with a single mold that can slide in the axial direction, maintaining the durability of the mold. Since it becomes easy to do, a leg part can be made into a thinner outer diameter.

  According to a second aspect of the present invention, in the first aspect, the elastic piece has one end connected to the outside of the pair of shaft portions and the other end connected to the back surface of the head, and the corresponding shaft portion. A pair of first elastic pieces arranged with a predetermined gap between them and a pair of second elastic pieces arranged with one end connected to the connecting portion and the other end connected to the back surface of the head A clip composed of a piece is provided.

  According to the above invention, the four elastic pieces including the pair of first elastic pieces and the pair of second elastic pieces can be arranged substantially evenly in the circumferential direction, and the elastic pieces are engaged with the back surface side of the mounting hole. When combined, a substantially uniform engaging force can be obtained without deviation in the circumferential direction, so that the clip can be stably fixed to the mounting hole.

  According to a third aspect of the present invention, in the first or second aspect of the invention, the pair of shaft portions provide a clip extending in an axial direction from the connecting portion.

  According to the said invention, since a pair of axial part is extended in the axial direction rather than the connection part, it becomes a guide at the time of inserting a leg part in an attachment hole, and can make it easy to insert. Further, by extending the pair of shaft portions long, a bending moment acts greatly when pressed against the inner periphery of the mounting hole, so that the pair of shaft portions can be more easily bent.

  A fourth aspect of the present invention provides the clip according to any one of the first to third aspects, wherein the pair of shaft portions has a shape protruding a predetermined amount toward the inner peripheral side of the annular coupling portion. It is.

  According to the above invention, since the pair of shaft portions has a shape protruding a predetermined amount toward the inner peripheral side of the annular connecting portion, the pair of shaft portions are pressed and excessively bent inward when the mounting hole is inserted. In this case, the inner peripheries of the pair of shaft portions abut against each other and can be prevented from further bending, and damage and loss of the pair of shaft portions can be prevented.

  According to the present invention, when the leg portion is inserted into the mounting hole, not only the elastic engagement piece but also the pair of shaft portions to which the elastic engagement piece is connected bend inwardly. Can be made relatively low, and the legs can be smoothly inserted into the mounting holes.

  In addition, since the pair of shaft portions are connected by an annular connecting portion disposed at a predetermined position in the axial direction and have an appropriate rigidity, unintended pulling force is applied to the clip attached to the mounting hole. Even if a twisting force is applied, these forces are received and a high holding force is obtained for the mounting hole.

  Furthermore, since the inside of the leg is a single continuous space, the shape of the inside of the leg can be molded with a single mold that can slide in the axial direction, maintaining the durability of the mold. Since it becomes easy to do, a leg part can be made into a thinner outer diameter.

The outer portion of 41b protrudes outward at a predetermined height and is formed thicker than the base portion 41a (see FIG. 2).

  Further, as shown in FIG. 1, the outer periphery of the tip portion 41b of the shaft portion 41 has a shape that is gradually reduced in diameter toward the tip. Furthermore, the axial side predetermined position of a pair of axial parts 41 and 41, in this embodiment, the base part side of the front-end | tip part 41b WHEREIN: The adjacent side parts of both the axial parts 41 and 41 are each in the flake-like connection part 45. As a whole, the pair of shaft portions 41 and 41 are connected in a ring shape (see FIGS. 1 and 5). As a result, the tip portions 41 b of the pair of shaft portions 41, 41 have a structure extending in the axial direction from the connecting portion 45, and the pair of shaft portions 41, 41 are provided on the inner peripheral side of the connecting portion 45. It has a shape protruding by a predetermined amount.

  Further, the leg portion 40 is provided with a plurality of elastic pieces 50 including a first elastic piece 51 and a second elastic piece 55.

  As shown in FIGS. 1-4, the 1st elastic piece 50 is arrange | positioned through predetermined space | gap S2 and S2 on the outer side of a pair of axial parts 41 and 41 (refer FIG.4 (b)), The one end ( The lower end is connected to the outer peripheral surface of the base end side of each tip end portion 41 b of the pair of shaft portions 41, 41, and the other end (upper end) is connected to the back side of the flange portion 27 of the head 20. A step-like engagement portion 51 a that engages with the rear side periphery of the mounting hole 3 is formed on the outer periphery on the upper end side of the first elastic piece 51. Further, the upper end portion 51 b of the first elastic piece 51 connected to the flange portion 27 has a thin piece shape provided substantially parallel to the axis of the leg portion 40.

  On the other hand, the second elastic piece 55 is located on both sides of the pair of first elastic pieces 51, 51, one end (lower end) thereof is connected to the connecting portion 45, and the other end (upper end) is the head. The structure is connected to the back surface side of the 20 flange portions 27 (see FIG. 4A).

It is arranged via predetermined gaps S3 and S3 with respect to the side portion. In addition, since each second elastic piece 55 is arranged on both sides of each first elastic piece 51, the shaft portion 41 and the first elastic piece 55 with respect to the gap S <b> 2 between the shaft portion 41 and the first elastic piece 51. The space S3 between the two elastic pieces 55 is disposed orthogonally (see FIG. 6). These gaps S3 and S3 are connected orthogonally to both ends of the space S1 between the shaft parts 41 and 41, and as shown in FIGS. Is provided.

  The clip 10 having the above structure can be manufactured by a mold shown in FIG. This mold slides in the direction of arrow E, opens and closes in the direction of arrows F1 and F2 in the mold 60 that molds the shape of the inner side of the above-described leg portion 40, and the outer shape of the clip 10 (the plate-like portion of the head 20). And a pair of dies 61 and 61 for forming the shape up to the upper end of the rim 21.

  The mold 60 has a substantially H-shape comprising a plate-like intermediate rib 60a and a pair of both-side ribs 60b, 60b connected orthogonally to both ends of the intermediate rib 60a. Shaped voids. Further, the pair of molds 61, 61 is provided with a protrusion 61 a that forms a gap S <b> 2 between the shaft portion 41 and the first elastic piece 51. The upper surface shape of the plate-like portion 21 of the head 20 is formed by a mold (not shown) that slides in the same direction as the mold 60.

  When the clip 10 is molded, the pair of molds 61 and 61 are closed, the mold 60 and a mold for molding the upper surface of the plate-like portion 21 (not shown) are set at predetermined positions, and then a synthetic resin is put into the cavity in the mold. The clip 10 is injection-molded by injection molding.

  In the clip 10, the inner side of the leg portion 40 forms a substantially H-shaped gap and forms a single continuous space. Therefore, the die 60 is slidable in the axial direction of the leg portion 40. Thus, the inner shape of the leg portion 40 can be molded, the durability of the mold 60 can be easily maintained, and the leg portion 40 can have a thinner outer diameter. In the mold 60 of this embodiment, since the pair of both side ribs 60b and 60b are connected by the intermediate rib 60a, even if the leg portion 40 is thinned and the both side ribs 60b and 60b become small, the intermediate rib 60a connected thereto. Thus, the rigidity of the mold 60 can be maintained.

  In addition, the pair of first elastic pieces 51, 51 are respectively disposed outside the pair of shaft portions 41, 41 via the pair of gaps S2, S2, and the pair of second elastic pieces 55, 55 are The inner gaps S3 and S3 are arranged so as to be orthogonal to the gaps S2 and S2 (see FIG. 6). Therefore, as shown by arrows F1 and F2, a pair of first elastic pieces 51 and 51 are formed by the protrusions 61a and 61a of the pair of molds 61 and 61 that slide in parallel to the direction connecting the pair of gaps S3 and S3. The inner shape can be molded.

  Furthermore, since the pair of second elastic pieces 55, 55 are disposed on both sides of the pair of first elastic pieces 51, 51, the inner gaps S3, S3 are formed of the pair of shaft portions 41, It communicates with the space S1 between 41. For this reason, the inner shape of the second elastic piece 55 can be simultaneously formed by the mold 60 for forming the inner shape of the pair of shaft portions 41, 41.

  Thus, the second elastic piece is formed by one mold 60 that molds the inner shape of the pair of shaft portions 41 and a mold 61 that slides in a direction perpendicular to the mold 60 (here, a direction connecting the pair of gaps S3 and S3). Since the inner shape of 55 and the 1st elastic piece 51 can be shape | molded, respectively, a type | mold structure can be simplified.

  Next, a method of using the clip 10 of the present invention having the above configuration will be described with reference to FIGS.

  As described above, the clip 10 is for temporarily fixing the glass 5 to the attached member 1. When the clip 10 is bonded to the glass 5, the adhesive G is applied to the upper surface of the plate-like portion 21 of the head 20, and then pressed against the glass 5, so that the adhesive G is spread and spread. It spreads to the periphery of 21. At this time, even if the adhesive G is about to overflow, it accumulates in the first annular recess 21a, so that the protrusion is prevented. When the clip 10 is further pressed against the glass 5, the clip 10 is joined to the glass 5 in a state where the peripheral wall portion 21c of the plate-like portion 21 is in contact with the glass surface (see FIG. 8A).

  After the above operation is repeated and the plurality of clips 10 are attached to the glass 5, the leg portions 40 of the clips 10 are aligned and pushed into the round hole-like attachment holes 3 provided in the attached member 1.

  Then, the pair of shaft portions 41 and 41 are inserted while being in sliding contact with the inner periphery of the mounting hole 3. At this time, since the pair of shaft portions 41, 41 extend in the axial direction from the connecting portion 45, the pair of shaft portions 41, 41 serves as a guide when the leg portion 40 is inserted into the mounting hole 3. Can be easy to insert.

  When the clip 10 is further pushed in, the pair of shaft portions 41 and 41 are pressed against the inner periphery of the attachment hole 3 and inserted while being bent inward. At this time, since the pair of shaft portions 41, 41 extend longer than the connecting portion 45, the bending moment acts greatly when pressed against the inner periphery of the mounting hole 3, so the pair of shaft portions 41, 41 Can be more easily bent.

  When the clip 10 is further pushed in from the above state, the pair of shaft portions 41 and 41 are pushed inwardly while being bent inwardly. Since it has a shape that protrudes by a predetermined amount on the peripheral side, even if the pair of shaft portions 41, 41 is excessively bent inward, the inner periphery thereof is prevented from colliding with each other and further bending is prevented. The breakage and loss of the pair of shaft portions 41, 41 can be prevented.

  When the connecting portion 45 reaches the mounting hole 3, the connecting portion 45 is pressed and bent to the inner periphery of the mounting hole 3, and when the base portion 41 a of the leg portion 40 reaches the mounting hole 3, it is shown in FIG. As described above, the outer circumferences of the pair of first elastic pieces 51, 51 and the pair of second elastic pieces 55, 55 are pressed against the inner circumference of the attachment hole 3 and are pushed in while being bent inward.

  At this time, since each elastic piece 51, 55 starts from the upper end portions 51b, 55b having a thin piece shape, the elastic pieces 51, 51 are bent as shown in FIG. 8 (a). The elastic pieces 51 and 55 can be bent relatively easily. Even in this case, as shown in FIG. 8B, the elastic pieces 51 and 55 are excessively bent by the pair of shaft portions 41 and 41 disposed inside the elastic pieces 51 and 55, respectively. Are suppressed, so that their breakage or loss is prevented.

  Then, when the engaging portions 51 a and 55 b of the elastic pieces 51 and 55 come out to the back side of the mounting hole 3, the engaging pieces 51 and 55 are elastically restored and are engaged with the engaging portion on the rear surface side periphery of the mounting hole 3. 51a and 55a are engaged with each other, the seal flange 29a of the head 20 is elastically engaged with the front peripheral edge of the attachment hole 3, and the attached member 1 is sandwiched between the both, and FIG. As shown in (b), the clip 10 is fixed to the mounting hole 3. As a result, the glass 5 can be fixed to the attached member 1 via the clip 10. Thereafter, a sealing agent (not shown) is filled between the outer periphery of the opening of a member 1 (not shown) such as a window frame and the peripheral edge of the glass 5, and the glass 5 is formed in the opening by curing it. Is fixed.

  As described above, in the clip 10, when the leg portion 40 is inserted into the mounting hole 3, only the pair of first elastic pieces 51 and 51 and the pair of second elastic pieces 55 and 55. In addition, since the connecting portion 45 to which the second elastic piece 55 is connected and the pair of shaft portions 41 and 41 to which the first elastic piece 51 is connected bend inward, the insertion resistance should be relatively low. The leg portion 40 can be smoothly inserted into the mounting hole 3.

  9A and 9B show a state in which the clip 10 is attached to the attachment hole 3. At this time, the pair of shaft portions 41, 41 of the clip 10 are connected by an annular connecting portion 45 disposed at a predetermined position in the axial direction and have an appropriate rigidity, so that the clip 10 is not intended. Even if a pulling force or a twisting force is applied, these forces are effectively received and a high holding force can be obtained for the mounting hole 3.

  By the way, in the said embodiment, although the leg part 40 of the clip 10 is being fixed with respect to the round hole-shaped attachment hole 3, in this clip 10, not only the round hole-shaped attachment hole 3 but other shapes It can be fixed to the mounting holes.

  For example, the clip 10 can be attached also to the elongated attachment hole 3a shown in FIGS. 10 (a) and 10 (b) where both ends are arcuate. That is, when the pair of second elastic pieces 55, 55 of the leg portion 40 of the clip 10 is inserted so as to be parallel to the long axis direction of the mounting hole 3a, it is shown in FIG. Thus, a pair of 1st elastic pieces 51 and 51 engage with the back side peripheral edge of the attachment hole 3a. Although not shown, when the pair of first elastic pieces 51, 51 are inserted in parallel to the long axis direction of the mounting hole 3a, the pair of second elastic pieces 55, 55 is now the back side of the mounting hole 3a. Engage with the periphery.

  Further, when the elastic pieces 51 and 55 are inserted without being aligned in the major axis direction of the mounting hole 3a as described above, as shown in FIG. 51a and 55a engage with the back side peripheral edge of the attachment hole 3a in half.

  In any case, in the clip 10 of this embodiment, since the pair of first elastic pieces 51, 51 and the pair of second elastic pieces 55, 55 orthogonal thereto are provided, the leg portion 40 is inserted into the mounting hole 3a. At this time, any one of the elastic pieces 51 and 55 can engage with the attachment hole 3a, and the clip 10 can be fixed to the attachment hole 3a.

  Further, in the clip 10 of this embodiment, the four elastic pieces 51, 51, 54, 54 are arranged substantially evenly in the circumferential direction and engage with the back side of the inner circumference of the mounting holes 3, 3a almost evenly. Therefore, the fixing force with respect to the attachment holes 3 and 3a can be obtained stably.
