  Since this swell is formed with two types of bulging portions, it can be attached to panels having different plate thicknesses.

JP 2004-100901 A

  However, since the conventional fasteners are formed so that the heights of the adjacent bulges are different and the heights of the bulges at the diagonal positions are the same, the bulges at the pair of diagonal positions are the same. In a state where the panel is locked by the portion, the bulging portions at other diagonal positions do not function, and the support state of the panel becomes unstable.

  The present invention has been proposed in view of the above circumstances. That is, it aims at providing the fastener which can latch a board member in the stable state.

  In order to achieve the above object, the present invention provides a column portion and a plurality of elastic leg portions that surround the column portion with a bending margin, and are connected to a head portion and are suspended, In the fastener for locking the penetrated plate member between the elastic leg portion and the head portion, the bending margin is formed by extending in the axial direction from the base portion where the head portion is connected among the elastic leg portions. And the thin plate locking shoulder for locking the thick plate member, which is a thick plate member, is positioned close to the base portion. A slit that is formed at a position far from the base portion and that extends in a width direction from the bending margin is formed in the base portion, and the locking shoulder portion for the thin plate faces the head portion across the slit. It is said.

  Further, the elastic leg portion is formed with an insertion resistance portion raised in the radial direction, and the insertion resistance portion is formed at a position different in the axial direction in the adjacent elastic leg portion.

  Further, the thin plate locking shoulder is formed away from the axis of the base in the width direction.

  Further, the locking shoulder for the thin plate is raised in the radial direction.

  Further, the bending margin is narrow at the base side and is wide at the tip side of the elastic leg.

  In the fastener according to the present invention, the bending margin is formed by extending in the axial direction from the base portion of the elastic leg portion to which the head portion is connected, and the locking shoulder portion for the thin plate that locks the thin plate member that is a thin plate member. The thick plate locking shoulder for locking the thick plate member, which is a thick plate member, is formed at a position far from the base at a position close to the base. With this configuration, the fastener can simultaneously lock plate members having different thicknesses with a plurality of elastic legs. Accordingly, the amount of engagement increases, and plate members having different thicknesses can be stably locked.

  In addition, the elastic leg portion has a slit formed in the base portion in the width direction from the bending margin, and the thin plate locking shoulder portion faces the head portion with the slit interposed therebetween. With this configuration, the locking shoulder for the thin plate is separated from the head by the slit and becomes a free end, so that a moment with the base as a fulcrum acts on the free end, and the elastic leg portion is easily bent. Therefore, the insertion force of the fastener can be reduced.

  In particular, it is preferable that an insertion resistance portion protruding in the radial direction is formed in the elastic leg portion, and the insertion resistance portion is formed at a position different in the axial direction in the adjacent elastic leg portion. With this configuration, the resistance when the fastener is inserted is distributed in two stages. Therefore, the insertion force of the fastener can be reduced.

  In particular, it is preferable that the locking shoulder for the thin plate is formed away from the axis of the base in the width direction. With this configuration, the length of the arm from the base portion serving as the fulcrum to the free end serving as the action point is increased, and the moment acting on the free end is increased so that the elastic leg portion is easily bent. Therefore, the insertion force of the fastener can be further reduced.

  In particular, it is preferable that the locking shoulder for the thin plate is raised in the radial direction. With this configuration, it is possible to ensure engagement with the plate member locked to the fastener. Therefore, the fastener can stabilize the holding force for holding the plate member.

  In particular, it is preferable that the bending margin is narrow on the thin plate engagement shoulder portion side and wide on the distal end side of the elastic leg portion. With this configuration, the elastic leg has a narrower bending margin, so the elastic leg has a wider width on the locking shoulder for the thin plate, and the arm length from the base portion to the locking shoulder for the thin plate is longer. As a result, the moment acting on the free end increases and the bending becomes easier. In addition, the elastic leg portion has a wide bending margin, the width on the tip side becomes narrow, and the elastic leg portion is easily bent. Therefore, the insertion force of the fastener can be further reduced.

  Embodiments of the present invention will be described below with reference to the drawings.

  In FIG. 1, the fastener 10 according to the present embodiment is attached to the head 40 so that the support column 20 and a plurality of elastic legs 30 surrounding the axis of the support column 20 with a bending margin 37 are suspended. It is connected and formed. For the fastener 10, for example, a material such as polyacetal (POM) is used.

  The head 40 is formed on the same axis from a substantially cylindrical neck 41 (see FIG. 2) and a small-diameter collar 42, a medium-diameter collar 43, and a large-diameter collar 44 around the neck 41. Has been configured. The small-diameter collar 42, the medium-diameter collar 43, and the large-diameter collar 44 each have a substantially annular shape that extends from the neck portion 41 in the radial direction. These are formed in the order of a small diameter ridge 42, a medium diameter ridge 43, and a large diameter ridge 44 from one end side of the neck portion 41 toward the support column portion 20, and the diameter gradually increases.

  In FIG. 2B, one end side of the neck portion 41 is depressed in the axial direction. The small diameter ridge 42 is extended in the radial direction from the edge on one end side of the neck portion 41. The medium diameter ridge 43 extends in the radial direction from the neck portion 41 with a space in the axial direction with respect to the small diameter ridge 42 and is formed in a substantially letter shape in the longitudinal section. That is, the medium diameter ridge 43 is once inclined in a direction approaching the small diameter ridge 42 from the neck portion 41 and then in a direction away from the small diameter ridge 42. The large-diameter collar 44 extends from the neck portion 41 in the radial direction from the connection portion between the neck portion 41 and the support column 20, and is inclined in a direction away from the medium-diameter collar 43.

  In FIG. 1, the column 20 is formed so as to protrude coaxially from the head 40. Moreover, the support | pillar part 20 is a cross shape with the cross-section of the long plate-shaped piece 21 orthogonally formed integrally (refer FIG.2 (c)), and the front-end | tip part 22 is narrowed in an axial direction. It is formed. Between the plate-like pieces 21, elastic leg portions 30 are respectively provided with bending margins 37.

  The entire shape of the elastic leg portion 30 is substantially rocket-shaped, and the diameter of the elastic leg portion 30 is gradually increased from the distal end portion 22 with the support column portion 20 as a central axis, and is connected to the head portion 40. The elastic leg portion 30 is supported by the tip portion 22 and the head portion 40, and extends in the axial direction from the tip portion 22 of the support column 20 to the head portion 40. As for the elastic leg part 30, the side connected with the front-end | tip part 22 is the front-end | tip base 32, and the side connected with the head 40 is the base 31. The elastic leg part 30 is comprised from the four fan-shaped pieces centering on the support | pillar part 20 in a cross section, and it is formed so that it may become a concentric circle with the head 40 (refer FIG.2 (c)).

  On the surface of the elastic leg portion 30, undulations are formed from the tip base portion 32 to the base portion 31 in the axial direction. This undulation is composed of an insertion resistance portion 36 that becomes resistance when the fastener 10 is inserted into the plate member, and a plate member locking portion 33 that locks the plate member. Further, the insertion resistance portion 36 is composed of a first insertion resistance portion 36a and a second insertion resistance portion 36b that disperse the resistance at the time of insertion in two stages, and the plate member locking portion 33 engages with a thick plate member. It is composed of a thick plate locking shoulder 34 that stops, and a thin plate locking shoulder 35 that locks a thin plate member.

  Here, in order to make it easy to understand the shapes of the undulations of the first insertion resistance portion 36a and the second insertion resistance portion 36b, the thick plate locking shoulder portion 34, and the thin plate locking shoulder portion 35, they are formed on the front side. The undulations formed on the side surface will be described with reference to FIG. 2 (a) viewed from the front, based on FIG. 2 (b) viewed from the side.

  In FIG. 2A, the insertion resistance portion 36 is formed such that the side surface side of the elastic leg portion 30 protrudes in the radial direction with respect to the end of the plate-like piece 21. Here, the insertion resistance portion 36 is different in the position in the axial direction between the adjacent elastic leg portions 30. That is, if the adjacent elastic leg portions 30 are a first elastic leg portion 30a and a second elastic leg portion 30b, respectively, the first elastic leg portion 30a is inserted into the first elastic leg portion 30a at a position approximately half in the axial direction from the distal end base portion 32. The resistance portion 36a is formed on the second elastic leg portion 30b, and the second insertion resistance portion 36b is formed at a position closer to the head portion 40 in the axial direction from the first insertion portion 36a.

  In FIG. 2B, the thick plate locking shoulder 34 is formed on the base 31 side by a first raised portion 39, which is raised on the front side of the elastic leg portion 30 in the radial direction with respect to the plate-like piece 21. It is a slope. Similarly, the thin plate locking shoulder 35 is a slope formed on the base 31 side by a second raised portion 38 that is raised in the radial direction with respect to the plate-like piece 21 on the front side of the elastic leg portion 30. In these, the second raised portion 38 is raised higher in the radial direction than the first raised portion 39.

  In FIG. 1 and FIG. 2A, the thin plate engagement shoulder 35 and the thick plate engagement shoulder 34 are formed at different positions in the axial direction. That is, in the axial direction, the thin plate engagement shoulder 35 is formed at a position close to the head 40 and the thick plate engagement shoulder 34 is formed at a distant position.

  The thick plate locking shoulder 34 is curved and formed in an arc shape in the width direction of the elastic leg 30, and continues to the second raised portion 38. The thick plate locking shoulder 34 is continuous with the base 31 in the axial direction. The second raised portion 38 is formed by a thin plate locking shoulder portion 35 that stands up and protrudes in the radial direction and inclines against the head portion 40.

  The thin plate locking shoulder portion 35 is opposed to the head portion 40 with a gap, since a slit 4 described later is formed in the base portion 31. The second raised portion 38 (thin plate locking shoulder 35) is spaced from the slit 4 and the bending margin 37 where the slit 4 is connected to the plate-like piece 21 and the head 40. The base portion 31 is a free end that bends toward the support column 20 side.

  In FIG. 1, the bending margin 37 is provided so as to be spaced between the support column 20 and the elastic leg 30, and extends in the axial direction from the base 31 side to the tip base 32. In the bending margin 37, a long hole in the axial direction penetrates the elastic leg 30 from the front side toward the center of the support column 20, and a long groove in the axial direction extends from the side to the center of the support column 20. The long hole and the long groove communicate with each other. The bending margin 37 is wide on the front base 32 side and narrow on the thin plate locking shoulder 35 side on the front side of the elastic leg 30. Further, on the side surface side, the elastic leg portion 30 and the plate-like piece 21 are formed in parallel.

  The slit 4 is formed in the base 31 so as to leave a space between the head 40 and the thin plate locking shoulder 35, and continues from the bending margin 37 in the width direction.

  The base 31 is formed near the end of the elastic leg 30 in the width direction by forming the slit 4. Thereby, the base 31 is formed away from the second raised portion 38 (the thin plate locking shoulder 35) in the width direction.

  The present embodiment is configured as described above. Next, a method of attaching the trim board to the automobile door panel 1 as a thin plate member that is a plate member will be described using the present embodiment, and the operation of the present embodiment will be described. The trim board is not shown.

  The trim board is usually formed with a substantially gourd-shaped hole. The hole is constituted by an insertion hole having substantially the same diameter as the small-diameter flange 42 of the head 40 and a locking hole having substantially the same diameter as the neck portion 41.

  The fastener 10 is inserted into the insertion hole from the small-diameter collar 42 side, and the neck portion 41 is inserted into the insertion hole. The fastener 10 is moved, the neck portion 41 is slid from the insertion hole to the locking hole side, and the removal direction of the locking tool 10 is regulated by the small-diameter ridge 42 having a shape larger than the locking hole. In this way, the neck portion 41 is locked in the locking hole, and the fastener 10 is attached to the trim board.

  In this state, the fastener 10 is attached to the door panel 1. When the elastic leg 30 penetrates the door panel 1, the fastener 10 is sandwiched between the elastic leg 30 and the head 40 and locked. Hereinafter, in order to facilitate understanding of the operation of the present embodiment, the state of the insertion resistance portion 36 will be described with reference to FIG. 3 as viewed from the front, and the state of the plate member locking portion 33 with reference to FIG. 4 as viewed from the side.

  In FIG. 3A, the fastener 10 is inserted into the mounting hole 2 formed on the door panel 1 from the front end 20 side and having a diameter smaller than the head 40 and slightly larger than the width of the plate-like piece 21. For example, if the diameter of the mounting hole 2 is 8.5 mm, the width of the plate-like piece 21 is about 8.3 mm. When the fastener 10 is inserted into the attachment hole 2 to approximately half, the fastener 10 is clogged in the attachment hole 2 by the elastic leg portion 30 that is gradually expanded in diameter from the distal end portion 22. That is, the first insertion resistance portion 36 a that protrudes in the radial direction from the plate-like piece 21 comes into contact with the edge of the mounting hole 2, and becomes resistance when the fastener 10 is inserted. On the other hand, the second elastic leg portion 30b adjacent to the first elastic leg portion 30a is in contact with the edge of the attachment hole 2 at this point because the position of the second insertion resistance portion 36b is formed closer to the head 40. In other words, there is no resistance when the fastener 10 is inserted.

  The elastic leg portion 30 (30a) extending in the axial direction while leaving a margin 37 to bend in the radial direction with respect to the support column 20 is regulated by the edge of the mounting hole 2, so that the central axis with the distal end base portion 32 and the base portion 31 as a base point Is bent inward toward the support column 20 and is reduced in diameter. The fastener 10 is further inserted while reducing the diameter of the elastic leg portion 30 (30a) until it has substantially the same diameter as the mounting hole 2.

  In FIG. 3B, the fastener 10 is again clogged in the mounting hole 2 by the elastic leg portion 30 whose diameter is increased as it approaches the head 40. In other words, the second insertion resistance portion 36 b bulging in the radial direction from the plate-like piece 21 comes into contact with the edge of the attachment hole 2, and becomes resistance when the fastener 10 is inserted. The elastic leg 30 (30b) is regulated by the edge of the mounting hole 2 so as to bend inward toward the support 20 which is the central axis with the distal end base 32 and the base 31 as a base point, and the diameter thereof is reduced. The fastener 10 is further inserted while the elastic leg 30 (30b) is reduced in diameter until it has substantially the same diameter as the mounting hole 2.

  4A and 4B, the elastic leg portion 30 is clogged in the mounting hole 2 by the first raised portion 39 and the second raised portion 38 that are raised in the radial direction from the plate-like piece 21. In particular, the second raised portion 38 that is raised higher in the radial direction than the first raised portion 39 comes into contact with the mounting hole 2, but the elastic leg 30 is regulated by the edge of the mounting hole 2, so that the tip base 32 and The base portion 31 is bent inward toward the support column 20 which is the central axis.

  Specifically, the second raised portion 38 (thin plate locking shoulder portion 35) that is separated in the width direction with the base portion 31 as an axis and that is a free end draws an arc-shaped track with the base portion 31 as a base point, and the column portion 20 side. As the plate-like piece 21 is bent, the restoring force that is within the attachment hole 2 and returns to the original diameter is regulated (see FIG. 5B). When the fastener 10 is further inserted, the second raised portion 38 passes through the mounting hole 2 and the restriction is released, and the elastic leg portion 30 returns to the original diameter by the restoring force. At the same time, the front end of the large diameter flange 44 comes into contact with the surface of the door panel 1, and the thin plate locking shoulder 35 formed at a position near the large diameter flange 44 contacts the back surface of the door panel 1. The large diameter rod 44 is bent so as to approach the horizontal, and the inclination angle is widened. In particular, since the second raised portion 38 is raised in the radial direction, the diameter of the elastic leg portion 30 is larger than the diameter of the mounting hole 2, and the fastener 10 is deeply locked to the door panel 1.

  In the fastener 10, the elastic leg portion 30 whose diameter has been reduced returns to its original diameter due to the restoring force, and the locking shoulder portion 35 for the thin plate formed at a position close to the large diameter flange 44 contacts the back surface of the door panel 1, The large-diameter rod 44 bent so as to approach the angle tries to return to the original inclination angle. In this way, a repulsive force due to elasticity is generated from the radial direction and the axial direction, and the fastener 10 is locked to the attachment hole 2 and attached to the door panel 1.

  Next, the state which attached the fastener 10 to the door panel 3 as a thick board member is demonstrated. In addition, since it is the same as that of the case of the door panel 1 as a thin plate member about an attachment method and an effect | action, description is abbreviate | omitted and only a different point is demonstrated.

  5A and 5B, the fastener 10 inserted into the mounting hole 2 of the door panel 3 is locked to the mounting hole 2 and attached to the door panel 3. The second raised portion 38 (thin plate locking shoulder portion 35) that is free in the width direction with the base portion 31 as an axis is bent toward the support column portion 20 side by drawing an arc-shaped track with the base portion 31 as a base point. As it approaches the piece 21, the restoring force that fits in the mounting hole 2 and returns to the original diameter is restricted. In particular, the elastic leg portion 30 having a large radius is greatly bent as the second raised portion 38 is raised in the radial direction. Further, the fastener 10 is bent so that the thick plate engagement shoulder 34 contacts the back surface of the door panel 3, the tip of the large diameter ridge 44 contacts the surface of the door panel 3, and the large diameter ridge 44 approaches the horizontal. The inclination angle is spreading.

  That is, the fastener 10 is formed at a position far from the large-diameter flange 44 by the second raised portion 38 pressing the inner side of the mounting hole 2 so that the elastic member 30 having a reduced diameter tries to return to the original diameter by a restoring force. The thick plate locking shoulder 34 comes into contact with the edge of the mounting hole 2 from the back surface of the door panel 3, and the large-diameter flange 44 presses the surface of the door panel 3. In this way, a repulsive force due to elasticity is generated from the radial direction and the axial direction, and the fastener 10 is locked to the mounting hole 2 and attached to the door panel 3.

  As described above, according to the present embodiment, the fastener 10 is locked to the door panel 3 at the position where the thin plate locking shoulder 35 to be locked to the door panel 1 is close to the large diameter flange 44 in the axial direction. Thick plate locking shoulders 34 are formed at positions far from the large-diameter flange 44, respectively. With this configuration, the fastener 10 can simultaneously lock either the door panel 1 or the door panel 3 having different thicknesses with all four elastic legs 30. Specifically, the thickness of the plate member that the fastener 10 can accept is 0.65 mm to 1.5 mm in the thin plate locking shoulder 35, and 1.4 mm to 2 mm in the thick plate locking shoulder 34. 3 mm. That is, the fastener 10 can accept a plate member having a thickness of 0.65 mm to 2.3 mm. Therefore, the amount of engagement increases and the door panels having different thicknesses can be stably locked.

  The elastic leg 30 is formed by extending a bending margin 37 in the axial direction from the base 31, the slit 4 is formed in the base 31 in the width direction from the bending margin 37, and the locking shoulder 35 for the thin plate is formed by the slit. 4 is opposed to the head 30. With this configuration, since the thin plate locking shoulder 35 is separated from the head 30 by the slit 4 to become a free end, a moment with the base 31 as a fulcrum is generated by the second raised portion 38 (thin plate locking shoulder 35). ), The elastic leg 30 is easily bent. Therefore, the insertion force of the fastener 10 can be reduced.

  Further, the elastic leg portion 20 is formed with an insertion resistance portion 36 protruding in the radial direction, and the first insertion resistance portion 36a and the second insertion resistance portion 36b are located at different positions in the axial direction in the adjacent elastic leg portions 30. Is formed. With this configuration, the insertion resistance portion 36 comes into contact with the edge of the mounting hole 2 at the time of insertion, and the resistance at the time of insertion of the fastener 10 is distributed in two stages between the first insertion resistance portion 36a and the second insertion resistance portion 36b. The Therefore, the insertion force of the fastener 10 can be reduced.

  Further, the second raised portion 38 (thin plate locking shoulder portion 35) is formed away from the base portion 31 in the circumferential direction. With this configuration, the length of the arm from the base portion 31 serving as a fulcrum to the second raised portion 38 serving as the action point (the thin plate locking shoulder portion 35) is increased, and the second raised portion 38 (the thin plate locking shoulder portion). 35), the moment acting on 35) is increased, and the elastic leg 30 is easily bent. Therefore, the insertion force of the fastener 10 can be further reduced.

  Further, the second raised portion 38 (thin plate locking shoulder portion 35) is raised in the radial direction. With this configuration, the fastener 10 has a larger amount of engagement because the diameter of the elastic leg portion 30 is larger than the diameter of the mounting hole 2 because the second raised portion 38 is raised. Since the fastener 10 has a large engagement margin, when the thin plate engagement shoulder 35 is engaged with the door panel 1, a deep engagement with the door panel 1 can be secured, and the removal direction is restricted. In addition, when the thick plate locking shoulder 34 is locked to the door panel 3, the second raised portion 38 comes into contact with the inside of the mounting hole 2, so that the elastic leg portion 30 having a larger radius is formed. Greatly bends to increase the resilience. Therefore, the fastener 10 can stabilize the holding force of the door panel.

  Further, the fastener 10 has a bending margin 37 that is narrower on the thin plate engagement shoulder portion 35 side and wider on the distal end base portion 32 of the elastic leg portion 30 on the front side. With this configuration, on the thin plate locking shoulder 35 side, the elastic margin 30 is widened by the narrow bending margin 37, and the length of the arm from the base 31 serving as the shaft to the thin plate locking shoulder 35 is increased. Becomes longer and the moment acting on the second raised portion 38 (the thin plate locking shoulder portion 35) is increased, so that it becomes easier to bend. Further, on the distal end base portion 32 side, the width of the elastic leg portion 30 is narrowed as the bending margin is wide, and the bending becomes easy. Therefore, the insertion force of the fastener 10 can be further reduced.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to the said embodiment. The present invention can be modified in various ways without departing from the scope of the claims.
