Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for a decorative molding to be attached to an outer panel of an automobile body.

As is well known, many moldings are attached to the body of a car, but these moldings are not only used for decorative purposes, but also serve a number of important functions, such as preventing harm to pedestrians. There are many cases.

The common method for installing such moldings is to make holes in the body and attach them with bolts or clips. Alternatively, there are problems such as rust occurring at the contact portion between the molding and the body outer panel.

Conventionally, in order to solve the above problems, a mounting structure as shown in FIG. 1 has been used.

FIG. 1 is a cross-sectional view showing the structure of a conventional installation, and the decorative molding 1 has almost the same cross section in the longitudinal direction, and by bending both longitudinal ends inward, a pair of rails 1 are attached. , lb are formed.

The rails 1a and 1b each have a resin protector 2a,
2b.

Reference numeral 4 denotes a fastener having a bolt 5 protruding from its substantially central portion, and is fitted into the molding 1 so as to be slidable in the longitudinal direction.

6 is a packing member made of rubber, resin, or the like.

The procedure for installing the molding 1 is to move the fixing tool 4 to the position corresponding to the mounting hole 3a provided in the body sheet metal member 3, insert the bolt 5 into the mounting hole 3a, and then tighten the nut 7 from the back side of the body sheet metal member. Tighten with.

At this time, since the resin protectors 2a and 2b are interposed between the molding 1 and the body sheet metal member 3, the body sheet metal member 3 is not damaged by the molding 1, and the body sheet metal member 3
The coating film on the outer surface of the molding 1 does not peel off, and electrolysis caused by the difference in ionization tendency between the molding 1 and the body sheet metal member 3, which are made of different metals, can be prevented.

Therefore, the occurrence of rust is also suppressed.

Furthermore, since the periphery of the hole 3a is sealed with a packing member 6 during installation, it is possible to prevent water from entering the inside of the body.

However, in the conventional structure as described above, since the fixing tool 4 freely moves in the longitudinal direction within the molding, even if the mounting is done in a position corresponding to the hole 3a, it will move with the slightest impact. When attaching one molding with several fasteners, it takes more time than necessary to position each fastener.

Furthermore, since rust prevention and water intrusion prevention are performed using separate parts, problems such as an increase in the number of parts remain.

The present invention has been devised in view of the above-mentioned drawbacks of the conventional structure.

The present invention will be explained below based on the embodiments shown in FIGS. 2 to 4.

Components that are substantially the same as those in FIG. 1 are designated by the same reference numerals, and detailed description thereof will be omitted.

The second is a sectional view of the attachment section, in which a fixing tool 4 with a bolt 5 protruding thereon is slidably fitted into the molding 1, similar to the conventional structure.

A protector 8 made of an elastic thin plate molded from synthetic resin or rubber is interposed between the fixing member 4 and the body sheet metal member 3, and the protector 8 includes:
As shown in FIG. 3, holding pieces 8a, 8a, ab, and 8b are formed by providing notches 8e at both ends thereof, and a through hole 8a for the bolt 5 is formed approximately in the center thereof.
is provided.

As shown in FIG. 4, the protector 8 has a clamping piece 8a on the outside and a clamping piece 8a on the inside with respect to the rail 1a.
Then, hold the rail 1a elastically, and similarly hold the rail 1b.
It is assembled so that it is held between the holding pieces 8b and 8b'.

Therefore, a suitable resistance is provided to the movement of the fixing member 4 within the molding, and the molding 1 can be quickly installed without moving again after positioning, and the body sheet metal member 3 and the molding 1 are not in direct contact. Holding pieces 8a, 8 without
rails la, lb of molding 1 to contact via b
Since the coating does not damage the outer surface of the body sheet metal member 3 and the coating film does not peel off, the occurrence of rust can be prevented.

In addition, since the protector 8 is interposed in a fairly wide range between the fixing tool 4 and the body sheet metal member 3, water does not enter between the rails la, lb of the molding 1 and the body sheet metal member 3, and water is prevented from entering. A sufficient sealing effect can also be obtained.

Note that, as in this embodiment, if an annular convex portion 8c is formed around the through hole 8d, the sealing performance is further improved.

Further, in this embodiment, three clamping pieces of the protector 8 are provided at each side edge, but any number of clamping pieces may be provided, two or more, and the number may be different at each side edge.

Since the present invention has the above-mentioned structure, it is not only easy to position the fixing device and make it easy to install it, but also to prevent rust and water from entering.
It is extremely rational, as it requires only a small number of parts because it uses a single protector.
