  By the way, in said patent document 1, since the vertical wall part of a clip attachment seat is long in U shape, and also there is a guide rib, the junction area with the interior goods back of a clip attachment seat becomes large, and it corresponds to the location concerned. Since sink marks are greatly generated on the surface of the interior product due to the difference in thermal shrinkage during molding, a meat stealing portion is recessed in the vertical wall portion of the clip mounting seat and the base end of the guide rib to reduce the joint area with the interior product back surface, The sink marks generated on the interior surface corresponding to these are made inconspicuous.

  However, if the meat stealing part is recessed at the base end of the vertical wall part and the guide rib, the thickness of the part becomes thin, the vertical wall part and the guide rib are easily bent, and the support rigidity of the clip is lowered. When the portion is shallow, the joint area with the back surface of the interior product becomes large, large sink marks are generated on the back surface of the interior product, and the appearance appearance is deteriorated.

  Further, since the clip engaging hole of the clip seating portion is opened to one end side of the clip seating portion by the taper guide portion, the clip seating portion is easily bent, and the clip is attached to the vehicle body panel when the interior product is assembled to the vehicle body panel. When trying to push into the assembly hole, there is a concern that the clip seat is bent and the clip is detached from the clip engagement hole.

  The present invention has been made in view of the above points, and its object is to increase support rigidity so that sink marks are not noticeable on the surface of an assembly panel such as an interior product and the clip does not come off during assembly. It is.

  In order to achieve the above object, the present invention is characterized in that the structure of the vertical wall portion and the clip seat portion in the conventional clip mounting seat is renewed.

  Specifically, the solution provided by the invention according to claim 1 is that a pair of legs are integrally projected at a distance from each other on the back surface of the resin assembly panel, and a bridge is formed at the projecting ends of both legs. The bridge portion is integrally connected so that there is a gap with the back surface of the assembly panel and at least one side end is opened, and the bridge portion includes a clip seat portion having a clip engagement hole and the clip seat portion. And the clip seating portion is positioned farther from the rear surface of the assembly panel than the guide surface portion, and the clip engaging hole is the step difference portion. A slit-like opening is formed in the stepped portion so as to be able to insert the engagement flange portion of the clip so as to communicate with the clip engagement hole. The engagement flange portion of the clip is formed on the guide surface portion. Slide along By lure the slit-shaped opening, characterized in that it is configured to be engaged with clips to clip engagement hole attached to the clip seat.

  The invention according to claim 2 is the invention according to claim 1, wherein the bridge portion is integrally formed so that both side ends are open and a flange is close to the rear surface of the assembled panel at one side end. It is characterized by being.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, when the assembled panel is assembled to the assembled panel, ribs that come into contact with the assembled panel are provided at the projecting ends of both legs. Each of them is integrally projected.

  According to the first aspect of the present invention, the clip seating part is integrally connected to the guide surface part via the step part, and the slit-like opening is formed in the step part and the clip-engaging hole is formed in the slit-like opening. Since the clip seating portion is not easily bent, the support rigidity can be increased so that the clip is not detached when the assembly panel is assembled to the assembly panel.

  Furthermore, the clip can be securely engaged with the clip engagement hole and attached to the clip seat by sliding the engagement flange of the clip along the guide surface portion and guiding it into the slit opening. Workability can be improved. Therefore, the guide rib as in Patent Document 1 is unnecessary, and the joint area with the back of the interior part of the clip mounting seat is reduced by that much, so that the sink marks are not noticeable, and the appearance can be improved.

  According to the invention of claim 2, the flange is separated from the back surface of the assembly panel, and the pair of legs projecting integrally on the back surface of the assembly panel are spaced apart from each other. Compared with the case where the joint portion with the panel is dispersed in two places and the joint portion is one place, the individual joint area is greatly reduced, the occurrence of sink marks can be further suppressed, and the appearance appearance can be improved.

  In addition, the bridge part is reinforced by the flange and is difficult to bend, and since the flange is close to the back of the assembly panel, when assembling the assembly panel to the assembly panel, attach the clip to the assembly panel. If it tries to push in to a hole, a flange will contact | abut to the assembly | attachment panel back surface because a clip seat part will bend by the reaction force. Therefore, the clip seating portion can be prevented from further bending and the clip can be prevented from being detached from the clip engagement hole, and the clip can be securely locked to the assembly hole of the assembly panel to cover the assembly panel. It can be securely assembled to the assembly panel.

  According to the invention of claim 3, when the assembly panel is assembled to the panel to be assembled, the ribs that are integrally provided at the projecting ends of the both leg portions are in contact with two locations that are separated from the panel to be assembled. Therefore, the assembly panel can be accurately and stably positioned on the assembly panel.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 7 shows an automobile V. Reference numeral 1 denotes a resin side sill protector (assembly panel) provided under the front and rear side doors 3a and 3b of the automobile V. The side sill protector 1 extends upward on the front side of the vehicle body. The front protector 5 constituting a part of the tire house and the rear protector 7 connected to the lower end of the front protector 5 and extending horizontally rearward of the vehicle body are divided, and as shown in FIG. Three screw insertion holes 5b are formed in the vertical wall 5a on the tire house side. In FIG. 3, reference numeral 5 c denotes a connecting portion with the rear protector 7.

  As shown in FIG. 1, the side sill protector 1 is assembled to a vehicle body panel 9 (an assembly panel) by clips 11 and grommets 13. Hereinafter, a case where the front protector 5 is assembled to the vehicle body panel 9 will be described.

  As shown in FIG. 3, a clip mounting seat 15 for attaching the clip 11 for assembling the front protector 5 to the vehicle body panel 9 is integrally formed at the upper end of the back surface of the front protector 5.

  Before describing the configuration of the clip mounting seat 15, the configuration of the clip 11 will be described. The clip 11 is made of resin, and as shown by a phantom line in FIGS. 1 and 4 and a solid line in FIG. 6, a locking part 11b is integrally formed at the tip of the shaft part 11a. A first engagement flange 11c is integrally formed at the base end of 11a, and a second engagement flange 11e is formed integrally with the first engagement flange 11c via a connecting portion 11d.

  As shown in FIGS. 1 and 2, the clip mounting seat 15 includes a pair of leg portions 17 that are integrally projected on the back surface of the front protector 5 with a space between each other, and at the base ends of the both leg portions 17. As a countermeasure against sink marks, the meat stealing portion 17a is recessed. A substantially rectangular bridge portion 19 is integrally bridged at the projecting ends of both leg portions 17, and a gap C <b> 1 is formed between the bridge portion 19 and the back surface of the front protector 5. Both side ends of the portion 19 on the side of the unconnected portion with both the leg portions 17 are open.

  The bridge portion 19 includes a clip seat portion 23 having a clip engagement hole 21 constricted in a substantially “<” shape, and a guide surface portion 27 integrally connected to the clip seat portion 23 via a step portion 25. The clip seat portion 23 is positioned farther from the back surface of the front protector 5 than the guide surface portion 27, and the clip engagement hole 21 extends to the step portion 25.

  The stepped portion 25 is formed with a slit-shaped opening 29 through which the second engaging flange 11 e of the clip 11 can be inserted so as to communicate with the clip engaging hole 21. In addition, vertical walls 31 are integrally formed on both side ends of the guide surface portion 27, both the vertical walls 31 are connected to the clip seat portion 23, and the guide surface portion 27 is behind the front protector 5 with respect to the clip seat portion 23. Is approaching.

  As shown in FIGS. 4 and 5, the bridge portion 19 is integrally formed at one side end of the bridge portion 19 so that the flange 33 is close to the back surface of the front protector 5 and the both leg portions 17 are connected. A gap C2 is slightly formed between the flange 33 and the back surface of the front protector 5. The reason why the flange 33 is formed only at one end on the open side of the bridge portion 19 is that it is necessary to advance and retract the slide mold during molding, and the flange 33 is on both sides of the open side of the bridge portion 19. This is because the slide mold cannot be advanced or retracted at the end.

  When the front protector 5 is assembled to the vehicle body panel 9, as shown in FIG. 1, ribs 35 that come into contact with the vehicle body panel 9 are integrally protruded from the protruding ends of the both leg portions 17.

  To attach the clip 11 to the clip mounting seat 15 configured as described above, as shown in FIG. 6, the second engagement flange portion 11 e of the clip 11 is placed on the guide surface portion 27 along the guide surface portion 27. The first engagement flange 11c and the second engagement flange 11e are clipped by causing the clip 11 to engage the clip engagement hole 21 by sliding to the slit-shaped opening 29 of the step portion 25. The clip 11 is attached to the clip seat portion 23 as shown by the phantom line in FIG.

  In order to assemble the front protector 5 (attached to the rear protector 7) with the clip 11 attached to the clip mounting seat 15 in this way to the vehicle body panel 9, first, as shown in FIG. In a state where 5 corresponds to the assembly position of the vehicle body panel 9, the portion corresponding to the clip mounting seat 15 of the front protector 5 is pressed from the front side, and the clip 11 is pushed into the assembly hole 9a of the vehicle body panel 9 to engage the locking portion 11b. Is engaged with the periphery of the assembly hole 9a, so that the front protector 5 is assembled to the vehicle body panel 9 (temporary assembly state). In this state, a screw hole (not shown) of the grommet 13 attached to the vehicle body panel 9 corresponds to the screw insertion hole 5 b of the vertical wall 5 a of the front protector 5.

  Next, the front protector 5 is screwed to the vehicle body panel 9 by inserting the screw 37 into the screw insertion hole 5b on the front protector 5 side, and screwing the screw 37 into the screw hole of the grommet 13 on the vehicle body panel 9 side. Assembly is complete. In addition, although description is abbreviate | omitted, the assembly | attachment to the vehicle body panel 9 of the rear side protector 7 is performed similarly.

  Thus, in this embodiment, the bridge portion 19 that bridges the protruding ends of the both leg portions 17 is formed to have a step between the clip seat portion 23 and the guide surface portion 27, and the slit-shaped opening 29 is formed as described above. Since the stepped portion 25 between the clip seating portion 23 and the guide surface portion 27 is formed so as to communicate with the clip engagement hole 21 of the clip seating portion 23, the support rigidity of the clip seating portion 23 is increased and is difficult to bend. When assembling 5 to the vehicle body panel 9, the clip 11 can be prevented from being detached.

  Further, in this embodiment, since the second engaging collar 11e of the clip 11 is slid along the guide surface portion 27 and guided into the slit-shaped opening 29, the clip 11 is clip-engaged with the clip seat portion 23. It can be reliably engaged with the hole 21, and the clip 11 can be easily attached to the clip seat portion 23 (clip attachment seat 15). Therefore, the guide rib as in Patent Document 1 is unnecessary, and the joint area between the clip mounting seat 15 and the back surface of the front protector 5 can be reduced by that much, so that the sink marks can be made inconspicuous, and the appearance can be improved.

  Further, in this embodiment, the flange 33 is separated from the back surface of the front protector 5, and the pair of leg portions 17 are integrally protruded from the back surface of the front protector 5 at a distance from each other so that two joint portions with the front protector 5 are provided. Since it is dispersed in the places, it is possible to greatly reduce the individual joining area as compared with the case of one joining place, further suppress the occurrence of sink marks and improve the appearance of the appearance.

  Furthermore, since the flange 33 is integrally formed at one side end of the open side of the bridge portion 19 so as to be close to the back surface of the front protector 5, the bridge portion 19 can be reinforced by the flange 33 so that it is difficult to bend. . In addition, since the flange 33 is close to the back surface of the front protector 5, when the front protector 5 is assembled to the vehicle body panel 9, the clip seat portion 23 is bent by the reaction force of the pushing force of the clip 11, so that it contacts the back surface of the front protector 5. The contact can be prevented from further bending, and the clip 11 can be prevented from coming off from the clip engagement hole 21. Further, the clip 11 can be reliably locked in the assembly hole 9 a of the vehicle body panel 9, and the front protector 5 can be reliably assembled to the vehicle body panel 9.

  In addition, in this embodiment, the ribs 35 are integrally projected at the projecting ends of the both leg portions 17, and when the front protector 5 is assembled to the vehicle body panel 9, the ribs 35 are spaced apart from the vehicle body panel 9. Since it is made to contact | abut at the location, the clip seating part 23 can be positioned to the vehicle body panel 9 accurately and stably.

  Further, in this embodiment, the meat stealing portion 17a is recessed at the base ends of the both leg portions 17, and measures against sink marks are taken, but the leg portion 17 tends to become unstable due to the meat stealing portion 17a. Stabilization can be achieved by connecting both leg portions with the bridge portion 19 and the flange 33.

  In this embodiment, both ends of the bridge portion 19 are opened. However, if sink marks are not so noticeable, the flange 33 is joined to the back surface of the front protector 5 so that only one side end is opened. The support rigidity of the clip seat portion 23 (clip mounting seat 15) can be further increased, which is preferable.

  Moreover, in this embodiment, although the case where the front side protector 5 was assembled | attached to the vehicle body panel 9 was shown, a pillar trim, a door trim, etc. may be sufficient, Furthermore, it can apply also to panel assembly structures other than automobile parts. Is.
