Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile door edge protector.

[0002]

2. Description of the Related Art Conventionally, as door edge protectors for automobiles, metal objects and synthetic resin objects are generally known. The former is manufactured by pressing stainless steel or aluminum, and is formed in a three-dimensionally bent shape according to the shape of the door edge. The latter includes those manufactured by extrusion molding of synthetic resin and those manufactured by injection molding of synthetic resin. The door edge protector manufactured by extrusion molding is configured by bending a flexible and linear shape three-dimensionally according to the shape of the door edge and attaching it to the door edge, and manufactured by injection molding. The door edge protector is preliminarily molded into a shape that is three-dimensionally bent according to the shape of the door edge, like a metal object.

However, the above door edge protector has the following problems.

With a metal door edge protector, when the door is carelessly opened and applied to a car parked next to it, the door edge of the car can be protected, but the body of the other car is damaged. Often, there is a problem in performance.

In the case of a metal door edge protector or a door edge protector manufactured by extrusion molding, since the end in the longitudinal direction is the cut surface of the material metal plate or the extrusion molded article, it does not look good in appearance as it is, Can't reach the important goal of dressing up door edge protectors. Therefore, in general, a small resin cap is attached to the end of the door edge protector to cover the cut surface of the material metal plate or extruded product, and the cap and its mounting labor are required separately from the door edge protector. To be done.

The door edge protector manufactured by extrusion molding is a three-dimensionally bent linear extrusion molded article conforming to the shape of the door edge and is attached to the door edge. In many cases, it cannot be bent properly.

That is, the side view shape of the door edge generally has a greater degree of bending than the rear view shape of the door edge (the shape of the door edge when the door is opened and viewed from the rear).
In the front door, the lower edge of the door edge may be bent at a substantially right angle, and in the rear door, there is a curved portion along the rear tire house on the lower half side of the door edge. In many cases, it is practically impossible to bend the extruded product in conformity with these shapes without causing any distortion. Therefore, the door edge protector cannot be attached over the entire length of the door edge, and it is used as a local door edge protector, or in combination with a door edge protector manufactured by injection molding,
Injection-molded products are attached only to the curved corners of the door edge.

The door edge protector by injection molding can avoid such inconvenience by molding into a shape corresponding to the shape of the door edge bent three-dimensionally. In order to perform injection molding, a large injection molding die having a large thickness is required, resulting in a very high manufacturing cost and an expensive product.

[0009]

SUMMARY OF THE INVENTION The present invention has been made in order to eliminate the above-mentioned conventional problems. It is possible to deform the door edge in accordance with the shape of the door edge, and the end is rounded. (EN) Provided is a high-performance automobile door edge protector which can be molded into a certain shape and does not have to be used together with a cap or a door edge protector by injection molding and can be manufactured at low cost.

[0010]

[Means for Solving the Problems] The technical means taken by the present invention to solve the above problems are as follows.
That is, the vehicle door edge protector according to the present invention is a rubber protector main body formed in a two-dimensionally elongated slender shape corresponding to the side view shape of the vehicle door edge, and the protector main body for attaching to the door edge. It is characterized in that it comprises a double-sided adhesive tape with release paper, and the protector body is three-dimensionally bent along the shape of the door edge and is attached to the door edge with the double-sided adhesive tape.

According to the above construction, the protector body made of rubber is two-dimensionally bent beforehand corresponding to the side view shape of the door edge, in other words, it is bent in a plane.
Since it is molded in a long and narrow shape, it can be reasonably transformed into a three-dimensionally bent shape along the door edge by pressing it against the door edge and adhering it with double-sided adhesive tape. Since it can be installed over the entire length, it is not necessary to use injection molded products together at the corners. Further, as described in claim 2, the longitudinal end of the protector body can be formed into a rounded shape, and it is not necessary to attach a cap to the longitudinal end of the protector body.

Since the protector body is made of rubber, when the door is opened carelessly and applied to a car parked next to it, not only the door edge of one's car but also the body of the other car is protected. be able to.

Since the protector body made of rubber is bent in a plane at the time of manufacture and is not bent three-dimensionally, a two-dimensionally elongated groove is cut on a flat surface. The protector body can be manufactured by using a so-called rubber molding die made of a pair of metal plates such as aluminum.

Therefore, as compared with the injection molding method, the cost of the molding die is low, and the protector body is not three-dimensionally bent at the time of manufacturing, so that the rubber molding having a small thickness is performed. By using a mold and devising the arrangement of the grooves to be engraved in the rubber mold, it is possible to mold multiple protector bodies at the same time with one rubber mold, greatly reducing the manufacturing cost. Therefore, a high-performance automobile door edge protector can be manufactured at low cost.

1 and 2, reference numeral 1 shows an example of an automobile door edge protector according to the present invention. As shown in FIGS. 3 and 4, the door edge protector 1 is made of rubber (in this example, synthetic rubber made in a slender shape that is two-dimensionally bent to correspond to the side view shape of the door edge 2 of an automobile. The protector body 3 and the double-sided adhesive tape 4 with the release paper 4a for attaching the protector body 3 to the door edge 2 are provided.

As shown in FIG. 4, the protector main body 3 includes a main plate portion 3a for covering the outer side portion of the door edge 2 and a bent plate portion for covering the tip of the door edge 2 which is continuously provided at one end in the width direction of the main plate portion 3a. 3b, and the double-sided adhesive tape 4 is attached to the back surface of the main plate portion 3a. The bent plate portion 3b is formed in a shape bent at a right angle to the main plate portion 3a. The longitudinal end of the protector body 3 is
The main plate portion 3a is formed in a rounded shape by providing inclined surfaces S that become thinner toward the door surface at both ends in the longitudinal direction.

Then, the release paper 4a is peeled off, and as shown in FIG. 5, the protector body 3 is pressed along the shape of the door edge 2 to bend it into a three-dimensional shape matching the shape of the door edge 2. Let double-sided adhesive tape 4
It is configured to be attached to the door edge 2. Since the automobile shown in FIG. 1 is a four-door type, a pair of left and right door edge protectors 1 corresponding to the door edges are attached to the front door a and the rear door b. FIG. 3 shows a pair of left and right door edge protectors 1 corresponding to the door edge of the front door a and a pair of left and right door edge protectors 1 corresponding to the door edge of the rear seat b.

In the door edge protector 1 described above, the protector main body 3 is formed in advance into a slender shape which is two-dimensionally bent corresponding to the side view shape of the door edge 2. By adhering with the adhesive tape 4, it can be reasonably deformed into a three-dimensionally bent shape along the door edge 3 and can be attached over the entire length of the door edge 2 having a large degree of bending. Also, since the protector body 3 is made of rubber, when the door is opened carelessly and applied to a car parked next to it, not only the door edge 2 of one's own car but also the body of the other car is protected. can do.

Incidentally, it is required for the door edge protector 1 for dressing up the automobile that the surface of the protector body 3 is painted in an appropriate color (for example, the same color as the body color of the automobile, a metallic color, etc.). It is desirable to achieve the important purpose of

At the time of manufacture, the protector body 3 is only two-dimensionally bent (in other words, in a plane) corresponding to the side view shape of the door edge, and is three-dimensionally bent. Therefore, as shown in FIGS. 6 (A) and 6 (B), a pair of metal plates 6a, 6 made of aluminum or the like in which two-dimensionally bent elongated grooves 5 are formed on a flat surface.
Using a so-called rubber molding die 6 composed of b, the synthetic rubber 7 in a softened state during vulcanization is molded into a predetermined shape, and after vulcanization,
The protector body 1 can be manufactured by removing the mold and cutting off the extra thin plate portion 7a as shown in FIG. 6 (C).

In this case, since the protector body 3 has a two-dimensionally bent shape (in the plane), thin metal plates 6a and 6b can be used as the rubber molding die 6. Further, even if the vertical and horizontal dimensions of the metal plates 6a and 6b forming the rubber molding die 6 are short, by devising the arrangement of the grooves 5 to be carved on the surfaces of the metal plates 6a and 6b, the metal plates 6a and 6b can be arranged.
On the surface of b, as shown in FIG.
(Or b) a plurality of pairs of protector body forming grooves 5 corresponding to (or b) are engraved, or, as shown in FIG. 7B, a protector body forming groove for one automobile, that is, A pair of protector main body forming grooves 5a corresponding to the front door a and a pair of protector main body forming grooves 5b corresponding to the rear seat door b are formed by engraving, etc. It is possible to manufacture the body 3.

Therefore, as compared with the injection molding method, the cost of the molding die is low, the thin rubber molding die 6 can be used, and one rubber molding die 6 protects a plurality of protector main bodies 3. Since it is also possible to mold simultaneously, the manufacturing cost can be significantly reduced and the high-performance automobile door edge protector 1 can be manufactured at low cost.
