Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a mounting structure for a kicking plate that fixes the end of a floor carpet at the end of a side sill of a vehicle body.

(Prior art and its problems) Floor carpets are laid on the floors of automobiles and the like from the standpoint of soundproofing and improving appearance quality.

Thus, the front and rear ends of the floor carpet are fixed to a member constituting the interior wall of the vehicle, such as a dash floor panel, and the opposite ends are fixed to the side sills using kicking plates.

Such a conventional mounting structure for a kicking plate is disclosed in, for example, Japanese Utility Model Application No. 59-76432, and FIG. 4 is shown as a conventional example in that application. The side end portion 3a of the floor carpet 3, which is laid with the sound absorbing material 2 interposed on the upper surface, is connected to the cabin side end portion 5a of the kicking plate 5 on the side sill 4 and the upper surface portion of the inner panel 4b of the side sill 4. It is clamped and fixed. Further, 6 is a reinforcing member fixed to the end of the floor carpet 3 to hold the end of the carpet 3.

In this case, the kicking plate 5 is fixed to the upper surface of the outer panel 4a of the side sill 4 via the clip 7, and is fitted and locked into the mounting hole 8 formed in the outer panel 4a. Because there is some clearance between clip 7 and sill side 4, it lacks watertightness and dustproofness.
Rainwater and dust were entering the interior and causing corrosion.

Further, the kicking plate 5 expands and contracts as the temperature rises or falls, which causes problems such as the clip 7 digging into the mounting hole 8 and the plate 5 being deformed.

Furthermore, due to manufacturing errors and construction accuracy, it is difficult to accurately match the positions of the mounting holes 8 and the clips 7 in advance, and when installing the plate 5, the mounting holes 8 are hidden from view by the operator. Therefore, there was a problem that the workability was further reduced.

(Purpose of the invention) The present invention was developed in view of these conventional problems, and improves watertightness and dustproofness, effectively prevents deformation of the tightening plate, and absorbs dimensional errors. The purpose of the present invention is to provide a mounting structure for a locking plate that is easy to install.

(Means for solving the problem) In order to achieve the above purpose, in this invention,
A first mounting member is formed in the shape of a box with an opening at the top and a hollow interior, and has a flange formed on the upper edge of the periphery, and a grommet portion into which a fixing screw is screwed, and the first mounting member is arranged in a longitudinal direction. and a second mounting member formed with a pair of elastic leg pieces that elastically abut and engage with both inner surfaces of the first mounting member. A first mounting member is fitted into a mounting hole drilled in a mounting member such as a vehicle body panel with a flexible waterproof washer interposed between the periphery of the mounting hole and the flange. While engaging the elastic leg pieces from the top opening of the first mounting member,
With the mounting member fitted in a predetermined position and the tightening plate placed on the upper surface of the second mounting member, a fixing screw is inserted into the grommet portion of the second mounting member through the mounting hole formed in the tightening plate. The second mounting member is expanded in the width direction by screwing them together, and the tightening plate is attached to the mounted member by engaging with the mounting hole of the mounted member through the first mounting member. It is characterized by a fixed mounting structure.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

1 to 3 show an embodiment of the present invention, FIG. 1 shows the configuration of the first mounting member 10 according to the embodiment, and FIG. 2 shows the structure of the second mounting member 10 according to the embodiment. FIG. 3 shows the structure of the member 11 and the mounting state of the kicking plate 5. As shown in FIG.

The first mounting member 10 has a substantially rectangular parallelepiped outer shape, is formed into a box shape with a predetermined wall thickness, with an open top surface 12 and a hollow interior, and a flange portion 13 is formed at the periphery of the upper end. .

Further, first locking portions 15 protruding outward are formed near the upper ends of both side walls 14 in the transverse direction, so that they can be engaged with mounting holes of a member to be mounted, which will be described later. There is.

Note that the first mounting member 10 is molded from a synthetic resin material having a predetermined flexibility.

The second mounting member 11 is formed into a shape that can fit into the hollow portion of the first mounting member 10 during use, and the side surface shown in FIG. 2a has a rectangular seat having a predetermined thickness at the top. A plate 16 is provided, and a screw hole 17 for a fixing screw, which will be described later, is formed approximately in the center of the seat plate 16.

In this embodiment, the screw hole 17 is formed in a long hole shape extending in a direction corresponding to the longitudinal direction of the first mounting member 10, as shown in FIG. 2c.

From the lower surface of the seat plate 16, a pair of leg walls 18, 18 are integrally extended so that the end edge of the screw hole 17 and its inner surface are flush with each other, and a grommet portion G is formed.
is formed.

That is, when a fixing screw (described later) is screwed into both leg walls 18 of the grommet portion G, the gap between the inner surfaces of both leg walls 18 is formed to be slightly smaller than the diameter of the screw, so that the two leg walls 18 are 18 are adapted to expand outward.

Further, on the outer surface of both leg walls 18, the first mounting member 18 is provided at a position facing the pair of first locking portions 15 of the first mounting member 10 when the first mounting member 10 is fitted. A second locking portion 1 having a shape corresponding to the first locking portion 15
9 are respectively protruded and formed.

Furthermore, as shown in FIGS. 2a to 2c, when the first mounting member 10 is fitted, the first mounting member 10 faces both inner surfaces 20, 20 (see FIG. 1b) in the longitudinal direction. A pair of flexible elastic leg pieces 2 extend from the lower end of each side of the leg walls 18.
1 and 21 are integrally formed in a protruding manner.

Further, 22 in FIG. 1 is a flexible waterproof washer of a predetermined thickness, which is attached in advance to the back circumferential surface of the flange 13 of the first mounting member 10.

In this embodiment, the waterproof washer 22 is made of neoprene closed foam.

Next, the first mounting member 10 and the second mounting member 1 are
The mounting structure of the locking plate according to this embodiment using the waterproof washer 1 and the waterproof washer 22 will be explained.

Reference numeral 23 in FIG. 3 is an outer panel of the sill side which is a member to be attached, and the outer panel 23
A mounting hole 24 into which the first mounting member 10 can be fitted is formed in advance at a predetermined position.

Then, the first mounting member 10 with the waterproof washer 22 attached thereto is pressed from the outside into the mounting hole 24,
When fitted, the waterproof washer 22 is flexible and therefore contracts slightly in the thickness direction, and the pair of first locking portions 15 of the flexible first mounting member 10,
15 is also elastically deformed and fitted into the mounting hole 24, and then engages with the inner edge of the mounting hole 24 due to elastic restoring force.

Next, the second mounting member 11 is fitted into the hollow interior of the first mounting member 10 through the upper surface opening 12.

At this time, both second locking portions 19 of the second mounting member 11
The leg walls 18 are slightly elastically deformed inward and engaged with the corresponding first locking portions 15 of the first mounting member 10, respectively.

In addition, in parallel with this, a pair of elastic leg pieces 21
advance into the interior while engaging with the inner side surfaces 20 of both longitudinal walls of the first attachment member 10, respectively.

In this case, assuming that the insertion position of the second mounting member 11 in the longitudinal direction of the first mounting member 10 is shifted from the normal position, the elastic leg piece 21 on that side will be lower than the other leg piece 21. Since the second mounting member 11 is also largely elastically deformed, the elastic restoring force becomes larger than that of the other leg piece 21, and due to the difference in the restoring forces, the second mounting member 11 moves to a position where both elastic restoring forces are balanced, that is, the normal mounting position. This eliminates the need to check and correct the mounting position each time.

After the second mounting member 11 is fitted into the predetermined position and the seat plate 16 at the top abuts and engages with the flange 13 of the first mounting member 10 to complete the mounting, the kicking plate 5 is 2 placed on the mounting member 11,
A mounting hole 25 previously formed at a predetermined position of the locking plate 5 is aligned with the threading hole 17 of the second mounting member 11, and a fixing screw 26 is screwed into the mounting hole 25 from outside.

At this time, one end of the kicking plate 5 is brought into contact with a side end of a floor carpet (not shown), as in the conventional example shown in FIG. 4 described above.

When the fixing screw 26 is screwed into the grommet part G of the second mounting member 11, both leg walls 18, 18 expand slightly outward, so that the second locking part 19 of both leg walls 18 The first mounting member 10 in contact with
The first locking portion 15 is pressed outward, and the first locking portion 15 is slightly elastically deformed outward and is firmly fixed to the periphery of the attachment hole 24 of the outer panel 23.

This completes the attachment of the kicking plate 5 to the outer panel 23.

In the mounting structure according to this embodiment, since the first mounting member 10 is mounted to the mounting hole 24 of the outer panel 23 via the waterproof shower 22, the joint between the first mounting member 10 and the mounting hole 24 is It is effectively sealed by the waterproof shower 22, and sufficient watertightness and dustproofness can be ensured.

Therefore, there is no risk of rainwater, dust, etc. entering through the joints as in the prior art.

Furthermore, since the fixing screws 26 are not directly fixed to the outer panel 23 as in the conventional case, but are joined via the flexible first mounting member 10 and second mounting member 11, the tightening plate 5 is Even if it expands or contracts due to temperature changes, the expansion,
The internal stress generated due to contraction is caused by the first mounting member 1
0 and the second mounting member 11 can absorb this by elastically deforming.

Therefore, it is possible to prevent the fixing parts of the kicking plate from biting into the mounting holes of the outer panel and from deforming the kicking plate as in the conventional case.

Further, as described above, the second mounting member 11 is connected to the first mounting member 10 by the action of the pair of elastic leg pieces 21.
Since it can be installed accurately in a predetermined position, there is no need to check whether the mounting position is accurate each time, improving work efficiency.

In addition, in the unlikely event that the mounting hole 2 of the scratching plate 5
5 and the screw hole 17 of the second mounting member 11 may be slightly shifted due to manufacturing error or construction error, because the screw hole 17 is a long hole, the fixing screw 25 As long as the tip of the fixing screw 25 is engaged with the screw hole, the elastic leg piece 21 will deform as the fixing screw 25 is screwed into the mounting hole 25 and the screw hole 17.
The relative position can be corrected.

Therefore, it is possible to absorb a certain amount of predictable dimensional error, so that the installation workability is significantly improved.

Note that even if the screw hole 17 is not made into a long hole, it is possible to absorb a certain degree of dimensional error only by the action of the elastic legs 21, so if the expected error is small, the screw hole 17 can be It goes without saying that various modifications can be made without departing from the gist of the present invention, such as an ordinary round hole.

(Effects of the invention) The present invention is constructed as described above, is highly watertight and dustproof, can effectively prevent deformation due to internal stress of the packing plate, has good workability, and has dimensional tolerances. It is possible to achieve various useful effects, such as being able to absorb the amount of water and making it easy to confirm the mounting position at the time of mounting.
