The body is stored in a storage chamber formed in the shaft portion of the pin in the suspended state.

  According to a third aspect of the present invention, on the premise of the second aspect, the engaging edge of the support portion is a slope along the inward support arm of the tilted holding body.

  According to a fourth aspect of the present invention, on the premise of the first to third aspects, the holding body has an outward drop-off preventing claw on the opposite side of the inward support arm, and the flange portion of the grommet has the drop-off preventing claw. It has the hook part which hooks.

  According to a fifth aspect of the present invention, on the premise of the fourth aspect, the upper surface of the hook portion of the flange portion of the grommet has a tapered shape.

  As for invention of Claim 6, on the premise of Claim 4, the hook part which the flange part of a grommet has has an upper wall where the upper surface is tapered, and a lower wall which extends radially below the upper wall, It is characterized in that a drop-off preventing claw of the holding body enters a recessed space defined between the upper wall and the lower wall.

  The invention of claim 7 is based on claim 4 and, at least in the lower end region of the support portion formed on the shaft portion of the pin, the inward support arm of the holding body is movable inward and outward of the support portion, When the inward support arm is moved inward of the support site, the holding body can be prevented from falling off, and when the inward support arm is moved outward of the support site, the support body is prevented from falling off. The nail cannot pass through the hook portion.

  The invention according to claim 8 is based on claim 1 and the head of the pin has a thick upper plate and a thin lower plate, and a tool insertion groove is provided between the upper plate and the lower plate. It is characterized by being defined.

  The invention described in claim 9 is based on the premise of claim 1 and is characterized in that the lower edge of the opening window formed in the body portion of the grommet is in close proximity to the lower surface of the outward holding piece of the holding body.

  As for invention of Claim 10, on the premise of Claim 1, the holding body consists of a pair, and the trunk of the grommet is divided into two or more divided leg pieces by a plurality of slits. An opening window for protruding and retracting the outward holding piece of each holding body is formed on one opposing divided leg piece, and a bulging protrusion that is engaged with the shaft portion of the pin and pressed outward is formed on the inner surface side thereof. It is characterized by that.

  The invention described in claim 11 is characterized in that, on the premise of claims 1 to 10, a pair of movement prevention walls is provided on both side edges of the storage chamber formed in the shaft portion of the pin.

  Therefore, in the first aspect of the invention, when the inward support arm of the holding body is supported by the support portion formed in the shaft portion of the pin, the holding body descends while sliding through the inward support arm. Therefore, when the pin shaft portion is inserted into the grommet body as it is, the pin and the grommet are temporarily placed while the holding body is present inside the body portion. After that, it is inserted into the corresponding mounting holes of the fixing target part, and the shaft part of the pin is further pushed into the grommet body part until the head part of the pin comes into contact with the flange part of the grommet. And the action of the pressure surface on the shaft side causes the outward holding piece of the holding body to protrude outward from the opening window formed in the grommet body, so that the flange portion of the synthetic resin grommet and the metal The fixed pair between the outer holding pieces of the holding body Object is clamped from inside and outside side, when compared with the conventional, and is surely secured with a strong clamping force securing the object with each other.

  In the invention according to claim 2, when the inward support arm of the holding body is engaged with the engaging edge of the support portion formed on the shaft portion of the pin and hung, the holding body itself is attached to the shaft portion of the pin. Inclining in the center direction, the outward holding piece is stored in the storage chamber of the shaft portion, so that it is easy to push the shaft portion of the pin into the grommet body while supporting the holding body. In this state, since the outward holding piece of the holding body is submerged in the opening window formed in the grommet body, the holding body can be inserted into the mounting hole of the fixed object. The outward holding piece of will not get in the way. In the invention described in claim 3, since the engaging edge of the support portion is an inclined surface along the inward support arm of the holding body, the holding body itself is reliably inclined in the center direction of the shaft portion of the pin. It is possible to make it disappear.

  In the invention of claim 4, under the temporarily fixed state of the pin and the grommet, the drop-out preventing claw of the holding body is hooked on the hook portion of the flange portion of the grommet, so that the temporarily fixed state is released, There is no worry about falling apart. In the invention of claim 5, when the shaft portion of the pin is inserted into the body portion of the grommet, the holding-off drop-off pawl supported by the shaft portion of the pin is guided by the taper shape of the hook portion. Therefore, the temporary fixing work is facilitated. In the invention according to claim 6, under the temporarily fixed state of the pin and the grommet, the drop-out preventing claw of the holding body enters into the recessed space defined between the upper wall and the lower wall of the hook portion. Therefore, in particular, the drop-off preventing claw of the holding body is reliably hooked to the hook portion of the flange portion.

  In the invention according to claim 7, under the state where the drop-out prevention claw of the holding body has moved inward of the support portion, the drop-off prevention claw can pass through the hooking portion of the flange portion of the grommet. When temporarily fixing the grommet, it is possible to easily temporarily fix it with a small force.On the contrary, after the temporary fixing, the drop-off prevention claw is moved under the condition that the drop-off prevention claw has moved to the outside of the support part. Since it cannot pass through the hook part of the flange part, even if it tries to pull out the shaft part of the pin from the body part of the grommet, it cannot be pulled out and there is no fear that the temporarily fixed state can be easily released.

  In the invention according to claim 8, the tip of a pin such as a screwdriver is inserted into the insertion groove defined between the thick upper plate and the thin lower plate of the pin head, Since the shaft part is pulled out from the grommet body part, the drawing work is facilitated. On the other hand, the inwardly supporting arm and the drop-off preventing claw of the holding body can be concealed by the thin lower plate.

  In the invention according to claim 9, since the lower edge of the opening window formed in the trunk portion of the grommet is in close proximity to the lower surface of the outward holding piece of the holding body, the holding object is held by the outward holding piece. In the state, the outward holding piece can be backed up at the lower edge of the opening window, and a reliable holding force of the outward holding piece can be provided. In the invention according to claim 10, when the divided leg piece of the grommet trunk is expanded outward, the lower edge of the opening window formed in the divided leg piece is the outward holding piece of the holding body. Therefore, the backup force for the outward holding piece can be obtained more effectively.

  In the eleventh aspect of the present invention, since the pair of movement preventing walls project from the both side edges of the storage chamber formed in the shaft portion of the pin, the shaft portion of the grommet is supported while the pin shaft portion supports the holding member. When inserting into the part, there is no fear that the holding body protrudes left and right outward from the storage chamber. As a result, the insertion operation into the grommet is always performed smoothly.

  In the present invention, the fastener itself is composed of three parts of a synthetic resin pin, a synthetic resin grommet, and a metal holding member, and when fixing an object to be fixed, the flange portion of the synthetic resin grommet By holding with the outward holding piece of the metal holding body, it is possible to firmly fix the fixed object as compared with the conventional one.

  Hereinafter, the present invention will be described in detail on the basis of preferred embodiments shown in the drawings. The stopper according to the first embodiment is different from the conventional one, and as shown in FIG. It consists of three parts, a resin grommet 11 and a metal holding body 21, but is characterized in that the following configuration is adopted for each of the parts 1, 11, and 21. In addition, regarding the metal holding body 21, it shall be used with a pair of relationship.

  Therefore, first, the synthetic resin pin 1 will be described. As shown in FIG. 2, the pin 1 includes a disk-shaped head 2 and a columnar shaft portion 3. It has a thick upper plate 2a and a thin lower plate 2b, and defines an annular insertion groove 2c into which the tool tip is inserted between the upper plate 2a and the lower plate 2b. Is formed with support grooves 4 as four support portions for supporting an inward support arm 22 of a holding body 21 to be slidable in the axial direction on each of one opposing side surfaces of the upper side, On each of the other opposing side surfaces, two pressing surfaces 5 for pressing outwardly holding gripping pieces 24 of the holding member 21 to be described later are formed outward, while holding members are provided on the intermediate part side continuing from each pressing surface 5. 21 is configured to form two storage chambers 6 that store the outward holding piece 24 side of 21 toward the center of the shaft portion 3. For each of the support grooves 4, an engagement edge 4 a is formed on the lower end side of the support body 21 to hang by engaging the inward support arm 22 of the support body 21, and the support body 21 tilts the engagement edge 4 a. In addition, a configuration of a continuous slope along the inward support arm 22 is employed.

  In addition, an annular large-diameter groove 7 that engages a split leg piece 17 of a grommet 11 (described later) is formed below the storage chamber 6 on the lower side of the shaft portion 3, and tapered from the large-diameter groove 7. An annular small-diameter groove 9 continuous through the surface 8 is formed, and a tapered guide protrusion 10 is suspended at the tip thereof. The shaft portion 3 is smoothly inserted into a trunk portion 13 of the grommet 11 described later.

  Next, as shown in FIG. 3, the synthetic resin grommet 11 includes a disk-shaped flange portion 12 and a cylindrical body portion 13, and the former flange portion 12 has a central portion of the body portion 13. While forming the opening 14 connected with a hollow area, it becomes the structure which forms a pair of hook part 15 which hooks the drop-off prevention nail | claw 23 of the clamping body 21 mentioned later on the opposing outer periphery, The upper wall 15a continues in the circumferential direction, the lower wall 15b extends in the radial direction below a part of the upper wall 15a, and the concave space 15c defined between the upper wall 15a and the lower wall 15b. In addition, the taper shape which guides the drop-off prevention nail | claw 23 of the clamping body 21 mentioned later shall be positively provided with respect to the upper surface of the upper wall 15a continuous in the said circumferential direction.

Further, the latter body portion 13 divides the peripheral wall into four divided leg pieces 17 through the slits 16 in the axial direction, and one of the four divided leg pieces 17 has one opposed divided leg piece 17. In addition, the opening window 18 for projecting and retracting the tip of the outward holding piece 24 of the holding body 21 is individually formed, and the outward holding of the holding body 21 is formed on the inner surface from the upper end edge of each divided leg piece 17 to the opening window 18. A concave groove 19 that allows the movement of the tip of the piece 24 is formed, and the large-diameter groove 7 and the small-diameter groove 9 of the shaft portion 3 of the pin 1 described above are engaged with the inner surfaces of the four split leg pieces 17. The bulging protrusion 20 is formed.

  Finally, the metal holding bodies 21 are used symmetrically as a pair, and as shown in FIG. 4, a bifurcated inwardly bent inward at the upper end edge of the vertically long main body 21a. The support arm 22 is formed, and an outward drop prevention claw 23 is formed on the opposite side of the inward support arm 22, while an outward holding piece 24 that is bent outward is formed at the lower end edge of the main body 21a. It has a configuration. In addition, the convex part 22a which faces in the support groove | channel 4 of the above-mentioned pin 1 shall be provided in the front-end | tip inner surface of the said bifurcated inward support arm 22. As shown in FIG.

  Then, when the pair of holding bodies 21 support the bifurcated inward support arms 22 in the corresponding support grooves 4 of the pin 1, the engagement width of the support grooves 4 is utilized using the groove width of the support grooves 4. While being supported by the edge 4a, the inward support arm 22 is supported so as to be movable inward and outward of the support groove 4. However, when the inward support arm 22 is moved inward of the support groove 4, In the state where the dropout prevention claw 23 of 21 can pass through the hooking portion 15 of the grommet 11 described above and the inward support arm 22 is moved outward of the support groove 4, the dropout prevention claw 23 is hooked on the grommet 11. It is set so that it cannot pass through the section 15.

  Therefore, when the trim board P1 which is an automobile interior part is fixed to a predetermined vehicle body panel P2 using the stopper having such a configuration, first, the support groove formed in the shaft portion 3 of the pin 1 is used. 4, when the bifurcated inward support arms 22 of the holding bodies 21 are engaged from the outside, the holding bodies 21 are lowered through the inward support arms 22 until they come into contact with the engaging edges 4 a. However, as described above, since the engaging edge 4a of the support groove 4 is a continuous downward slope, the pair of holding bodies 21 are arranged in the center direction of the shaft portion 3 as shown in FIG. While tilting, the main body 21 a side including the outward holding piece 24 is supported in a state of being housed in the housing chamber 6 of the corresponding shaft portion 3.

For this reason, even when the shaft portion 3 of the pin 1 is inserted into the trunk portion 13 of the grommet 11, the presence of the pair of holding bodies 21 does not get in the way. However, in terms of dimensions, the tip portion of the outward holding piece 24 of each holding body 21 protrudes slightly outward from the outer peripheral surface of the shaft portion 3, and the protrusion of the outward holding piece 24 is inserted into the body portion 13. At this time, since it can be absorbed by the concave groove 19 of each of the divided leg pieces 17 described above, there is no problem.

  Therefore, next, the shaft portion 3 of the pin 1 that supports the pair of holding bodies 21 while being tilted is inserted into the body portion 13 of the grommet 11. In this case, the holding portion that slightly protrudes outward is provided. When the distal end portion of the outward holding piece 24 of the body 21 and the concave groove 19 are inserted in alignment, each holding body 21 is guided while being guided by the taper shape of the upper wall 15a constituting the hooking portion 15 on the grommet 11 side. 6 is moved inward at the lower end portion of the support groove 4, so that the drop prevention claws 23 of the holding bodies 21 can smoothly pass through the upper wall 15a, as shown in FIG. The guide protrusion 10 of the pin 1 protrudes outward from the distal end edge of the body portion 13 of the grommet 11, and the pin 1 and the grommet 11 are temporarily fixed.

In this case, as shown in the drawing, the bulging protrusion 20 of each split leg piece 17 of the trunk portion 13 is engaged with the small diameter groove 9 of the shaft portion 3, so that each split leg piece 17 is still expanded. Although not opened, the outward holding pieces 24 of the holding bodies 21 are completely submerged in the trunk portion 13 of the grommet 11 without protruding outward from the corresponding opening windows 18.

Further, the contact of the guide projection 10 with the tip edge of the body portion 13 prevents the pin 1 from coming off, but in addition to this, the drop-out preventing claw 23 of the holding body 21 is provided with the hook portion 15. After passing through the upper wall 15a, the inward support arm 22 of each holding body 21 moves outward at the lower end of the supporting groove 4 on the slope of the engaging edge 4a of the supporting groove 4, and Since the drop-off preventing claw 23 enters the recessed space 15c defined between the upper wall 15a and the lower wall 15b, the pin 1 is prevented from coming off, and the three parties 1, 11, 21 are There is no worry of falling apart carelessly.

Therefore, after obtaining the temporarily fixed state of the pin 1 and the grommet 11, the trim board P1 is overlaid on the vehicle body panel P2, and the trunk portion 13 of the grommet 11 is inserted into the matching mounting holes H1 and H2. Further, when the shaft portion 3 of the pin 1 is completely pushed into the body portion 13 of the grommet 11 until the head portion 2 of the pin 1 comes into contact with the flange portion 12 of the grommet 11, the storage chamber 6 of the shaft portion 3 is now turned on. The outward holding piece 24 side of each holding body 21 stored in the inside is pressed by the pressing surface 5 of the shaft portion 3, and the outward holding piece 24 of each holding body 21 is formed on the split leg piece 17 facing the grommet 11. 7 so that the trim board P1 and the vehicle body panel P2 hold the flange portion 12 of the synthetic resin grommet 11 and the metal holding body 21 outwardly as shown in FIG. Is sandwiched between the 24, both P1 · P2 may have a strong clamping force obtained from a synthetic resin and a metal, and be firmly polymerization fixed. For this reason, in this embodiment, the reliability in the fixed state is further improved.

  Further, in this fixed state, as shown in the figure, when the pin 1 is pushed in, the bulging protrusion 20 of each divided leg piece 17 is now engaged with the large-diameter groove 7 formed in the shaft portion 3 of the pin 1. As a result, the trim board P1 and the vehicle body panel P2 can be held by the spread of the divided leg pieces 17. Accordingly, this also helps to support a strong fixed body, but the split leg piece 17 without the opening window 18 is positively held especially on the side where the metal holding body 21 does not exist. Since it becomes involved, a uniform holding force can be obtained over the entire circumference.

  Furthermore, when the outward holding piece 24 of the holding body 21 protrudes outward from the opening window 18 of the split leg piece 17, the lower edge of each opening window 18 comes close to the lower surface of the outward holding piece 24. However, in this case, when the corresponding divided leg piece 17 is expanded outward, the lower edge of the opening window 18 formed in the divided leg piece 17 supports the lower surface of the distal end portion of the outward holding piece 24 of the holding body 21. Therefore, the backup force for the outward holding piece 24 can be obtained more effectively, and the metallic outward holding piece 24 will not be bent.

On the contrary, when the trim board P1 and the vehicle body panel P2 are released from the fixed state as necessary, the tip of a tool such as a flat-blade screwdriver is inserted into the insertion groove 2c defined on the side surface of the head 2 of the pin 1. (Not shown), when the shaft portion 3 of the pin 1 is pulled up from the body portion 13 of the grommet 11 to the temporarily fixed state described above, the pressure surface 5 formed on the shaft portion 3 of the pin 1 is pressed. In addition, since the outward holding piece 24 side of each holding body 21 is stored again in the storage chamber 6 of the shaft portion 3, the distal end portion of the outward holding piece 24 is submerged in the trunk portion 13 of the grommet 11. After the inward support arms 22 of the pair of holding bodies 21 are moved inwardly in the support groove 4, each drop-out preventing claw 23 can pass through the upper wall 15a of the hook portion 15. In this state, the shaft 3 of the pin 1 together with the holding body 21 When completely pulled out from the body 13 of the rommet 11, the pin 1 and the grommet 11 as well as the pin 3 and the shaft 3 of the pin 1 from the body 13 of the grommet 11 are not deformed unnecessarily. It can be pulled out with a small force. Therefore, this also makes it possible to reuse the stopper itself.

  Next, the stopper according to the second embodiment will be described. The second embodiment is basically the same as the first embodiment described above. As shown in FIG. 8, a pair of movement prevention walls 30 are integrally projected in a parallel state on both side edges of the two storage chambers 6 formed on the shaft 3 side of the pin 1, while the head of the pin 1. The lower plate 2b constituting the lower plate 2b is cut at the peripheral edge on the side of the support groove 4 and at the position directly above the edge of the cut 31, a ridge 32 parallel to the cut 31 edge is provided on the upper plate 2a. It is a thing.

  Therefore, in the second embodiment, when the holding body 21 is supported by the shaft portion 3 of the pin 1 and inserted into the trunk portion 13 of the grommet 11 due to the presence of the pair of movement preventing walls 30 described above. As shown in FIG. 9, since the holding body 21 never protrudes from the storage chamber 6 in the left-right direction, the insertion operation is always performed smoothly. Note that the pair of movement prevention walls 30 are provided so as to protrude in a vertical direction on the mold structure, but the present invention is not limited to this, and as shown in FIG. It is also possible to integrally project over the entire area of both side edges of each storage chamber 6.

Further, the formation of the cut 31 on the lower plate 2b makes it easy to insert the tip of a tool such as a flathead screwdriver into the lower surface of the upper plate 2a, so that the pin 1 can be pulled out from the body portion 13 of the grommet 11. In particular, in this case, since the cut 31 is formed on the support groove 4 side avoiding the holding body 21, the holding body 21 is damaged at the tip of a tool such as a minus screwdriver when the pin 1 is pulled out. Can also be prevented.

Furthermore, the provision of the ridge 32 parallel to the edge of the cut 31 on the upper plate 2a means that the tool tip can be moved from the direction perpendicular to the ridge 32 when the tool tip such as the above-mentioned minus driver is inserted. It is possible to insert them to the depth just below the ridges 32 in parallel, so that the tool tip can be inserted as far as possible without interfering with the holding body 21 and damaging it. By doing so, the pin 1 can be pulled out more easily and with a light force. In the second embodiment, as shown in FIG. 8 and FIG. 9, the ridge 32 is provided as a mark at the time of this operation, but the present invention is not limited to this. As shown in FIG. 10, it is possible to make the mark as a concave stripe 33. However, in addition to the convex stripe 32 and the concave stripe 33, the marking is applied to the position corresponding to the edge of the cut 31 on the upper plate 2a. There may be.
Other configurations, functions, and effects are the same as those in the first embodiment, and thus description thereof is omitted here.

  Since the fastener according to the present invention can firmly fix the object to be fixed with a strong holding force by positively using a metal holding body, in particular, an interior / exterior part of an automobile is attached to a predetermined body panel. In the case of fixing, it is convenient.
