Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a mounting structure for plate-like members, and more specifically, it relates to a mounting structure for a plate-like member, and more specifically, a plate-like member such as a footrest or garnish, or a The present invention relates to a mounting structure for mounting a member having a shaped portion.

(Prior art) As such a conventional mounting structure, for example, the sixth
To explain the case of attaching the automobile footrest 1 as shown in the figure to the body panel 2, as shown in Fig. 7, a hole 5 for inserting a clip with a stepped part 4 is provided in the footboard part 3 of the footrest 1, and this hole The boss 6 concentric with 5 protrudes to the back side, and the boss 6
A hole 8 for inserting a stud bolt 7 protruding from the body panel 2 is provided in the bottom plate portion of the body panel 2, and a cover plate 10 that fits into the stepped portion 4 is provided at the upper end of a synthetic resin cylindrical clip 9. Each of the shaped bodies was provided with an engaging pawl 11 that protruded toward the inner periphery thereof. As shown in FIG. 8, the clip 9 is inserted into the boss 6 through the hole 5 in advance, and the stud bolt 7 is pushed into the inner circumference of the clip 9 to engage the pawl 11 with the thread groove of the stud bolt 7. The footrest 1 was attached to the body panel 2 by the pressing action of the cover plate 10 of the clip 9 fixed to the body side.

(Problem that the invention attempts to solve) However, in this mounting structure, there are no holes 5 in the tread portion 3.
Since the boundary line between the footrest 1 and the lid plate 10 appears, there is a problem in that the design of the footrest 1 becomes unsightly.

Furthermore, if such a plate-shaped member mounting structure is applied to a panel on the outer surface of a car body (for example, when installing a pillar garnish), it will be difficult to insert the plate-shaped member into a clip during rain or car washing. There was also a problem in which water entered through the joint between the hole and the clip.

Therefore, the technical problem to be solved by this invention is to make it possible to connect the boss of a plate-shaped member and the male screw on the body side through a clip without providing a hole for inserting the clip in the plate-shaped member. do.

Another object of the present invention is to provide a mounting structure for a plate-like member that can be mounted to a panel on the body side without any problem even if the male thread on the body side has a slight inclination.

(Means for Solving the Problem) A technical means for solving the above problem is to provide a concave boss having a diameter sufficiently larger than that of the male screw of the boss provided on the back side of the plate-like member, and having a male screw protruding from the body side. The mounting structure is such that the male thread is inserted into the hole and the male screw and the boss are connected via a clip, and the clip has an elastic shape that is perpendicular to the male thread and has a base plate portion that covers the concave boss hole. The base plate is made of a deformable sheet metal material, and the base plate portion has an inner claw that can engage with a male screw, and an outer claw that can engage with a protrusion or a recess formed on the wall of the boss. and are each provided to be elastically deformable.

(Function) The clip is attached to the boss from the back side of the plate member by covering the concave boss hole. When attaching the boss of the plate-like member to the male screw, the base plate portion is perpendicular to the male screw. The concave boss hole has sufficient room for the male thread. During installation, the claws on the outer circumferential side are elastically deformed and enter into engagement positions with the protrusions or recesses formed on the wall of the boss. Further, the claw on the inner circumferential side is engaged with the male screw.

(Example) Next, a first example of the present invention will be described based on FIGS. 1 to 3.

A boss 13 having a square cross section is integrally provided on the back side of a plate member 12 such as a tread portion of a footrest. 13A is a concave boss hole with an opening at the bottom, and has a sufficiently large diameter for a stud bolt 16, which will be described later. An engaging recess 14 is formed at an appropriate position on the outer peripheral side of the wall of the boss 13.
Note that the front side of the plate member 12 is formed into a single continuous surface.

On the other hand, a stud bolt 16 protrudes from a panel 15 such as an automobile body panel.

Next, the clip 17 is integrally formed by punching and bending a sheet metal material that can be elastically deformed, and is attached to the left and right sides of the base plate 18, which has approximately the same shape and size as the cross section of the boss 13. A pair of clamping plates 19 are raised up from the side ends so as to be inclined slightly inward from the perpendicular direction. The base plate 18 becomes a portion that covers the concave boss hole 13A. A rectangular punched portion 21 is formed in the center of the base plate 18 from which four engaging claws 20 of a predetermined shape are protruded centripetally. Each pawl 20 projects slightly upwardly, and a circular space 22 for insertion is left between the tips of the four pawls 20, the diameter being slightly smaller than that of the stud bolt 16. Further, rectangular punching portions 23 are provided near the upper ends of the sandwiching plates 19, and the portions above the punching portions 23 are folded back to the outside.
An engagement pawl 24 corresponding to the engagement recess 14 projects downward and inward from the upper edge.

The mounting structure of this embodiment is formed by the boss 13, stud bolt 16, and clip 17 as follows. That is, first, the clip 17 is attached to the boss 13 from the back side of the plate member 12. At this time, use the outward folded portion provided at the upper end of the pair of clamping plates 19 as a guide, and use the pair of clamping plates 19 as a guide.
While elastically deforming the clip 9 outward, the clip 17 is fitted to the outer peripheral wall of the boss 13 so as to fit over the concave boss hole 13A. Then, as shown in FIG. 3, the claw 24 is engaged with the recess 14. Since the claw 24 receives an inward biasing force from the clamping plate 19, it does not come out of the recess 14.

Next, this clip 17 is assembled to the stud bolt 16. That is, the stud bolt 16 is inserted into the insertion circular space 22 at the center of the clip 17 from below. At this time, the stud bolt 16 advances while pushing the claws 20 apart. When the footrest is inserted to a predetermined depth (for example, when the base of the footrest lands on the body panel), the pawl 20 bites into the thread groove of the stud bolt 16 at that position. Since the pawl 20 is inclined upward, it resists the stud bolt 16 from coming off.

In this way, the plate member 12 is attached via the clips 17 to the panel 15 provided with the stud bolts 16. Therefore, there is no need to provide a hole for inserting a clip on the front side of the plate member 12.

In this embodiment, instead of the recess 14, a protrusion that can be engaged with the claw 24 may be provided on the outer peripheral side of the wall of the boss 13. Further, the boss 13 and the clip 17 are not limited to having a rectangular cross-sectional shape or a planar shape. The clip 17 is not limited to one made of sheet metal.

Next, a second embodiment of the present invention will be described based on FIGS. 4 and 5.

A thin engagement wall 27 is formed along the lower end of the inner peripheral side of the wall of the boss 26, which is integrally provided on the back side of the plate member 25 and has a rectangular cross section, and a convex portion 28 is formed at an appropriate position on the wall surface. has been done. 26A is a concave boss hole that is open at the bottom and has a larger diameter than the stud bolt 16.

Next, the clip 29 is made of a sheet metal material that can be elastically deformed, and has claws 3 that can engage the recess 28 from the four sides of the rectangular base plate 30 corresponding to the boss 26.
1 is made to protrude slightly downward and outward. The rectangular punched portion 21 provided at the center of the base plate 30 and the four engaging pawls 20 provided therein have the same configuration as in the first embodiment.

In this embodiment, as shown in FIG. 5, the clip 29 is fitted into the engagement wall 27 by engaging its pawl 31 into the recess 28, and then the clip 29 is inserted into the stud. It is attached to the bolt 16.

The other aspects of the structure, operation, and effects of this embodiment are the same as those of the first embodiment.

(Effects of the invention) According to the mounting structure of the invention, there is no need to provide a hole for inserting a clip on the front side of the plate-like member. Water ingress can be avoided.

In addition, when the clip in the present invention is fitted over the concave boss hole, it becomes perpendicular to the male thread, and since the concave boss hole has a sufficiently large diameter relative to the male thread, there is some inclination to the male thread on the body side. Even if the plate member is tilted, it can be attached to the body panel without any problem.
