No. 7-32353

  In the mounting structure of Patent Document 1, both the clamping surface of the flange 4 and the stepped portion 3a which is the clamping surface of the locking piece 3 are flat surfaces, and the hole edge 5a of the drain hole is clamped between the flat surfaces. To do. For this reason, in this mounting structure, for example, if a drain hole or mounting hole is provided on the curved surface portion 7a of the mounted plate 7 as illustrated in FIG. A stable mounting state cannot be obtained. Conventionally, when such a drain hole or attachment hole is provided in the curved surface portion, it has been produced as a single point uniform clip corresponding to the curved surface, that is, as a dedicated clip.

  The object of the present invention is to solve the above-described problems, and is stable even if the mounting hole (including a drain hole) is provided in the curved surface portion of the plate to be mounted or the curvature of the curved surface portion is different. It is to be able to obtain the attached state. Other purposes will be clarified in the following description.

In order to achieve the above object, the present invention has a flange-shaped head and a rectangular locking leg projecting from the head, and a mounting hole provided in the curved surface of the mounted plate. A clip that is attached in a state in which the locking leg is inserted, and a protrusion that is provided on the back surface of the head and contacts the surface side of the mounting plate, and a U-shaped slit on both side walls of the locking leg The mounting plate is sandwiched by a projection provided at a free end of the locking piece partitioned by the contact and abutting on the back side of the mounting plate, and the head is provided on the back surface and the locking leg. An insertion piece portion that is inserted into the attachment hole before the locking leg and is in contact with the back surface of the attached plate, and an elastic portion that is formed on the side facing the insertion piece portion is provided. And the said to-be-attached board is clamped by the said insertion piece part and the said elastic part, It is characterized by the above-mentioned.

  In the present invention described above, the “attached plate” includes, for example, an automobile panel, a water tank, a wall member constituting a housing or casing of a device, and the like. The “mounting hole provided in the curved surface portion” is not limited to the configuration in which the entire hole of the mounting hole is provided in the curved surface portion as illustrated in FIG. 1, and a part of the mounting hole is provided over the curved surface portion. Including configurations.

The present invention as described above is more preferably embodied as in the following claims 2 to 4 .
(1) The projection of the head and / or the projection of the locking leg has a configuration in which a tip end surface is formed in a substantially circular arc shape with a smaller (curvature) cross section than the curvature of the curved surface portion of the mounted plate ( Claim 2).

(2) The protrusion of the locking leg and the protrusion of the head are opposed to each other, and one or more of the protrusions are formed.

On the other hand, the fourth aspect specifies that the above clip is used as a sound insulating material or a sealing material attached to a drain hole provided in a vehicle structural plate. However, it is needless to say that the use of the clip of the present invention is not limited to the sound insulating material and the sealing material as long as the mounting hole is provided in the curved surface portion.

According to the first aspect of the present invention, the protrusion provided on the back surface of the head and abutting on the surface side of the mounting plate, and the free ends of the locking pieces defined by the U-shaped slits on both side walls of the locking leg. The mounted plate is clamped by a projection provided and abutting against the back side of the mounted plate. In this mounting structure, even if the mounting hole is provided on the curved surface of the mounted plate, the mounting plate, that is, the hole edge of the mounting hole, is sandwiched between the small projections on the surface, so it is several steps more stable than before. Accordingly, a fixing force as designed can be applied.

  Further, according to the present invention, the locking leg is provided at a distance from the locking leg and is inserted into the mounting hole and comes into contact with the back surface of the mounted plate. The insertion piece part can be inserted first when inserting it so that the insertion operation can be performed easily, or the movement of the entire clip is regulated by the contact state of the insertion piece part with the mounting plate, so that a more stable fixing force can be obtained. Make it maintainable.

In addition, in this invention, in addition to clamping the mounting plate between the protrusions, the mounting plate is also clamped by the insertion piece portion and the elastic portion, so that, for example, even when the head is relatively large as in the embodiment A stable fixing force can be applied.

According to the second aspect of the present invention, since the tip end surface of the protrusion on the head and / or the tip end surface of the locking leg is formed in a substantially arc shape in cross section smaller than the radius of curvature of the curved surface portion of the mounted plate, Compared to the structure sandwiched between the surfaces, it becomes easier to adjust to the curvature of the curved surface portion, and accordingly the fixing force can be increased.

In the invention of claim 3, the protrusion of the locking leg and the protrusion of the head face each other, and one or more protrusions of both protrusions are formed as illustrated in FIG. 3B. For example, in a specification in which the clip and the attachment hole are large, it is easy to maintain a stable clamping mode.

The invention of claim 4 specifies the above uses, can provide each of the advantages described above as a clip, and can also provide reliability.

It is a figure which shows the attachment aspect of the said clip corresponding to FIG. 2 as a modification which changed the curvature of the curved surface part of the said to-be-attached board. (A) And (b) is explanatory drawing which shows the structure of patent document 1. As shown in FIG.

  Embodiments of the present invention will be described with reference to the drawings. In this description, the structure of the clip, its usage example, and the modification will be described in detail in this order. Each figure is considerably enlarged from the prototype of the invention.

(Structure) The clip 1 of the embodiment is a resin injection-molded product as shown in FIGS. 1 to 7, and includes a flange-shaped head 2, a locking leg 3 projecting from the head 2, and an engagement. It has elastic locking pieces 4 provided on both side surfaces of the fixed leg 3 and is mounted in a state in which the fixed legs 3 are inserted into the substantially rectangular mounting holes 8 provided in the curved surface portion 7a of the mounted plate 7. Type.

  The main main parts are provided on the back surface of the head 2 so as to be in contact with the front surface side of the mounting plate 7 and are inserted into the mounting holes 8 so as to be in contact with the back surface side of the mounting plate 7. The mounting plate 7 is clamped by the protrusion 14a provided on the locking piece 4 of the leg 3, and the head 2 is provided at a distance from the locking leg 3 and inserted into the mounting hole 8 to be mounted. 7 has an insertion piece portion 5 abutting against the back surface, the head 2 is formed with an elastic portion 11 on the side facing the insertion piece portion 5, and the attached plate 7 is connected to the insertion piece portion 5. For example, it is sandwiched between the elastic portions 11. These details will be clarified below.

  As can be seen from FIG. 2, the head 2 is curved in the same direction as the curved surface portion 7 a of the mounting plate 7, is formed relatively thick, and protrudes from the locking leg 3 and the insertion piece 5. The upper and lower parts of the main body 10 include a thin-walled elastic portion 11 formed by extending the side facing the insertion piece portion 5. The elastic portion 10 is in pressure contact with the surface of the attachment plate 7 with the clip 1 attached to the attachment hole 8.

  The main body 10 has a dimension that covers the mounting hole 8 with a margin. The main body 10 is provided in the middle of the width of the plurality of lateral ribs 13 provided on the outer surface 10 and the rear surface 10b and faces the base 5a of the insertion piece 5. The vertical rib 10c, the stepped portion 6 provided at the end opposite to the elastic portion 11 in a state where the locking leg 3 is inserted and attached to the mounting hole 8, and a plate of the stepped portion 6 It has an opening 19 provided in the middle of the width and communicating with the inside of the locking leg 3, and a protrusion 15 that is located on both sides of the base of the locking leg 3 and abuts on the surface side of the mounted plate 7. Further, for example, in FIGS. 5 (b) and 6 (c), reference numeral 20 is a vertical rib projecting from the inner bottom surface of the locking leg 3 on the back surface 10b of the main body, and reference numeral 21 is a back surface 10b of the main body. And a vertical rib projecting between the locking leg 3 and the insertion piece 5.

  Among these, the lateral rib 13 is a slip stopper that makes it easy to hold the clip during the clip mounting operation. The vertical ribs 10c are for allowing by attaching a line at the center when the mounted plate 7 such as a panel is curved in the horizontal direction of FIG. The point is the rib 10c that avoids the clip 1 because the clip 1 floats when it is faced. As shown in FIG. 1A, the stepped portion 6 forms a gap for drainage between the mounting hole 8 and the corresponding end side in a state where the locking leg 3 is inserted and attached to the mounting hole 8. The opening 19 makes it easy to discharge the liquid that has entered the locking leg 3.

  The protrusions 15 on both sides are provided on the coaxial line. In addition, each protrusion 15 is formed in a substantially arc-shaped cross section with at least a distal end surface having a curvature smaller than the curvature of the curved surface portions 7 a and 7 b of the mounted plate 7. In this example, the whole is bowl-shaped. Such a shape is stable even when the curvature of the curved surface portions 7a and 7b is different because the main body 10 abuts on the surface side of the mounting plate 7 via the arc surface of each projection 15, that is, in line contact. Keep state. Each vertical rib 20 and 21 is for reinforcement.

  The locking leg 3 has a bottomed cylindrical shape with a rectangular cross section corresponding to the mounting hole 8. On both side walls of the locking leg 3, the elastic locking pieces 4 are defined by a U-shaped slit, that is, two vertical slits 16 and a lower slit 16 a connecting the slits 16. When viewed from above, each locking piece 4 protrudes outward as it goes downward, and is attached with elastic displacement to the inner side of the locking leg 3 with the upper connecting portion as a fulcrum in the process of insertion into the mounting hole 8. It passes through the hole 8 and is restored to the original state simultaneously with the passage. Reference numeral 17 denotes a stepped portion provided on the upper end side of the lower wall portion of the locking leg 3, and reference numeral 18 denotes an anti-slip device provided on the outer surface of the lower wall portion of the locking leg 3.

  Further, as shown in the enlarged views of FIGS. 2 and 5 (a), the free end of each locking piece 4 has a protrusion 14a that contacts the back side of the mounting plate 7, and a protrusion 14a. A pair of small protrusions 14b are provided so as to protrude to the back side.

  The protrusion 14a is opposed to the protrusion 15 with a slight gap, and the tip end surface is formed in an R shape or a substantially arcuate cross section smaller than the curvature radius of the curved surface portions 7a and 7b of the mounted plate 7. In such a shape, in a state where the locking leg 3 is inserted into the mounting hole 8, it comes into contact with the back surface side of the mounted plate 7 through the arc surfaces of the protrusions 14 a on both sides, that is, point contact or line contact. Thus, a stable contact state is maintained even if the curvature of the curved surface portions 7a and 7b is different. This is the same as the protrusion 15.

  On the other hand, each small protrusion 14b is positioned one step deeper than the protrusion 14a, that is, closer to the inside of the locking leg 3, and inside the mounting hole 8 with the locking leg 3 inserted into the mounting hole 8. It is a place to be inserted into.

  The insertion piece 5 is connected to the base 5a and the base 5a on the back surface 10b of the main body and connected to the locking leg 3 with a predetermined gap as shown in FIGS. 3 and 6A. And a tip portion 5b extending from the elastic portion 11. The base 5 a has an arc shape, one end of the arc is connected to the back surface 10 b, and the other end of the arc maintains a predetermined gap with the main body 10. The tip portion 5 b is substantially parallel to the elastic portion 11 in the molded state and extends longer than the elastic portion 11.

(Usage example) In the above clip 1, as shown in FIGS. 1 and 2, the mounted plate 7 has a curved surface portion 7a, and is fixed to the mounting hole 8 provided in the curved surface portion 7a. Moreover, it is also fixed to the mounting hole 8 provided in the curved surface portion 7b illustrated in FIG. That is, FIG. 7 is a modified example in which the curved surface portion 7b is different from the curvature of the curved surface portion 7a, and the rest is the same as the above embodiment. The mounting hole 8 also serves as a drain hole similar to that of Patent Document 1. Therefore, the clip 1 is an example that acts as a sound insulating material that suppresses sound intrusion or a seal material that suppresses liquid intrusion when the clip 1 is mounted in the attachment hole 8, but is used for other purposes except for the attachment structure. Can also be deployed. Next, the procedure for the mounting operation will be described.

(A) In the mounting operation of the clip 1, first, the distal end of the insertion piece 5 is inserted into the mounting hole 8. In that case, when the insertion piece 5 is slightly inserted into the attachment hole 8, the elastic portion 11 hits the surface side of the attachment plate 7, so that the attachment plate 7 is sandwiched between the insertion piece 5 and the elastic portion 11. Become. From this state, when the head 2 is pushed forward along the elastic portion 11 and the entire clip 1 is moved a little, the locking leg 3 is also automatically inserted into the mounting hole 8.

(B) Finally, when the portion of the head 2 directly above the locking leg 3 is pushed in the direction of the mounting hole 8, the locking pieces 4 on both sides pass through the mounting hole 8 while elastically reducing the diameter. At the same time, the original state is restored. As a result, the clip 1 holds the mounting plate 7, that is, the hole edge of the mounting hole 8 between the projection 15 on the back surface 10 b side of the main body and the projection 14 a on the locking piece 4 side, and inserts the mounting plate 7 into the insertion piece. It is sandwiched between the part 5 and the elastic part 11. The former clamping force particularly restricts the periphery of the locking leg 3 in the head 2, and the latter clamping force particularly restricts the side of the head 2 away from the locking leg 3 in the longitudinal direction. Technically, the removal force is generated by the locking leg 3 (that is, the clamping force by the projection 15 and the projection 14a), and the attached plate 7 is in a positional relationship between the insertion piece 5 and the clamping by the elastic portion 11. R, that is, the rotation of the clip 1 with respect to the curved surface portions 7a and 7b is suppressed.

(C) In other words, the clamping force of the former is relatively small even if the mounting hole 8 is provided in the curved surface portions 7a and 7b because the projection 15 and the projection 14a are easily adapted to the curvature of the curved surface portions 7a and 7b. Since the mounted plate 7 is clamped between the protrusions 14a, 15, the clamping mode is more stable than the conventional one, and accordingly, a fixing force as designed can be reliably applied. Further, in this structure, the distal end surface of the protrusion 5 on the head 2 side and / or the distal end surface or the contact surface of the protrusion 14a on the locking piece 4 side provided on the locking leg 3 is the radius of curvature of the curved surface portions 7a and 7b. Since the cross section is formed in a substantially circular arc shape, it becomes easier to adjust to the curvature of the curved surface portion than in the conventional structure sandwiched between flat surfaces, and the fixing force can be improved accordingly.

(D) The latter clamping force is applied to the mounting hole 8 because the insertion piece 5 is provided at a distance from the locking leg 2 and is inserted into the mounting hole 8 and comes into contact with the back surface of the mounted plate 7. When the stop leg 3 is inserted, the insertion piece 5 can be used as an insertion guide, thereby facilitating the insertion operation. Further, by forming a contact state of the insertion piece portion 5 with respect to the mounted plate 7, the movement of the entire clip is restricted, and a more stable fixing force can be maintained. In addition, since the mounted plate 7 is sandwiched between the insertion piece 5 and the elastic portion 11 in addition to the clamping between the former projections 15 and 14a, the head 2 is, for example, as in the embodiment. Even when it becomes relatively large, a more stable fixing force can be applied.

(Modification) The above-described clip 1 can be modified as follows as required.
First, as illustrated in FIG. 3B, the protrusions 15 are formed so as to be opposed to the protrusions 14 b of the locking leg 3 and to form two or more protrusions 15. In this case, two or more protrusions 14a may be formed instead of the protrusion 15, or two or more of both the protrusion 15 and the protrusion 14a may be formed. For example, it becomes easy to maintain a stable clamping mode in a specification in which the clip 1 and the mounting hole 8 are large. In the case of forming two or more protrusions 15 or protrusions 14a is a curvature of the curved portion 7a and 7b may be by Ru varied as required Unishi the size of each projection in consideration.

Second, the shapes of the protrusions 15 and the protrusions 14a may not be substantially arc-shaped in cross section, but may be triangular or the like.
Thirdly, the head 2 includes a shielding portion or a cover (not shown) that covers a gap for draining formed between the stepped portion 6 and the corresponding end side of the mounting hole 8 so that the drainage can be drained right above. Is added as necessary.

Fourth, the use of the clip 1 is as an example other than the form. For example, the clip 1 is configured as a holder by forming a holding portion for holding a wire or the like on the head 2, or a hook or the like for hooking a small article. You may make it comprise for a latching tool by forming a part.

  As described above, the clip of the present invention only needs to have the configuration specified in each claim, and details can be changed or developed with reference to this form and modification.
