Abstract

(57) [Summary] [Problem] To protect the door edge of a vehicle easily and effectively without making the door edge of the vehicle inconspicuous. SOLUTION: In order to increase the frictional resistance in a hairpin-shaped cross-section and a transparent irregular-shaped extrusion molding, the tip of which is provided with a cavity or the like so that it can be easily deformed, and the inner surface contacting portion of the clamping portion is increased. The body color through the door edge protection material of the present invention, so that it can be easily attached without using adhesives or adhesives, and at the same time, it does not give any discomfort to the body color I was able to see it.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a protective material for preventing a door edge or a contacted object from being damaged by collision or contact of a door edge when opening and closing a door of an automobile.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, metal products such as aluminum, copper, and stainless steel, or hard plastic molded products coated with vapor deposition or opaque and colored have been widely known as door edge protection materials for automobiles.

[0003]

[Issues to be solved by the invention]

 The former, which is described in the prior art, is extremely effective against impacts and abrasions.However, when installing to the door, the method of caulking from the front and back of the door is used, so scratch the painted surface of the door. In addition, there was a problem that the door was opened at the parking lot and the vehicle touched the next vehicle, causing damage to the contacted vehicle even if the door edge of the vehicle was not damaged.

Further, the protective material of this metal product is only metal color, and there is a sense of incongruity with the body of an automobile which has become full color recently. As a result, the door edge was too conspicuous and the quality of private cars, especially high-grade cars, was degraded, and there was a problem that users were refraining from using conventional door edge protection materials.

[0005] On the other hand, the latter hard plastic protective material has an excellent function of protecting itself and others from being scratched, unlike the metal plastic protective material. However, when it is attached to the door, it easily comes off at the curved portion of the door. -There was a problem that irremovable dirt was generated at the edge when replacing the protective material because adhesive was required.

[0006] It is easy to color a hard plastic protective material to a color approximating the vehicle body color, but in order to meet the demands of general users, a considerable number of color tones must be prepared, which is economical. There was a problem that was inconsistent with trying to provide at a reasonable price.

[0007] In consideration of the above situation, the present invention opens the door inconspicuously even if the protective material is attached and damages the door edge and other vehicles even when the door is in contact with the garage wall or another vehicle. The aim is to provide a door edge protection material that can be easily installed without the need for adhesives or adhesives when installing the protection material, and does not come off even if it is a curved part of the door once it is installed. Is what you do.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the door edge protective material of the present invention is natural rubber, synthetic rubber or synthetic resin which is transparent, has elasticity and flexibility, and is excellent in heat resistance, weather resistance and abrasion resistance. It is a shaped extruded product composed of a composition and formed into a hairpin shape in cross section by an extrusion molding method, and has a strip-shaped protrusion in the length direction at an inner surface contact portion of a clamping portion thereof. It is a long one with a cavity in the length direction at the tip of the protective material. This protective material is cut to the required length and is attached by simply pushing it into the door edge.

The synthetic rubber or synthetic resin composition can be selected from chloroprene rubber, butadiene rubber, silicone rubber, polyamide resin, polyvinyl alcohol, vinylidene chloride resin, modified polyolefin resin, and the like.

In the present invention, a plurality of thin tongues are provided on the inner surface contact surface of the protective material holding portion, and a plurality of thin tongues are directed from both front and rear sides to the tip of the protective material. In the case where the tongue deviates, the tongue-like object is greatly deformed and acts like a reverse valve. The shape of the projection is not limited to the tongue-shaped one, and any other shape can be used as long as the projection is deformed by a pulling force and exerts a reverse supporting effect.

Further, the cavity provided at the tip of the protective material of the present invention protrudes from the door when attached to the door edge, and when the door is opened and the edge contacts something, the tip is deformed. The door edge or the contact object can be prevented from being damaged.

[0012]

[Embodiment of the invention]

 Next, the door edge protection material of the present invention will be described in detail with reference to the drawings. The door edge protection material (1) of the present invention is formed by extruding a compound obtained by adding a very small amount of a transparent dye to a synthetic rubber such as SBR using an extruder for rubber to have a width of 15 to 20 mm and a thickness of 6 to 10 mm. The cross section is formed in a hairpin shape.

[0013] The tip part (2) of the molded door edge protective material is protruded to such an extent that it does not hinder when the door equipped with the protective material is closed, and the door is opened to contact a wall or another vehicle. In this case, the tip portion (2) is deformed so that it can be prevented from being damaged. By providing the cavity (4) at the tip, it was easier to deform.

The inner surface of the holding portion (3) of the door edge protection material may be a flat surface having a large rubber-like frictional resistance with respect to the painted surface of the door edge, but as shown in FIG. A projection (5) such as a tongue-shaped plate, a simple corrugated shape or irregularities is provided at the inner surface contact portion of 3). Could be prevented.

[0015] By making the door edge protective material transparent and attaching any body color to the door, the body color of the edge portion is not impaired, so that the door edge does not appear to be edged, The image of the vehicle is not impaired. Of course, coloring a transparent color of the same color as the body color to enhance the body color is also suitable for that purpose.

[0016]

[Effects of the Invention] Since the present invention is configured as described above, the following effects can be obtained.

Since the cross section is a hairpin shape and no adhesive or adhesive is used for the inner contact surface of the pinching portion, the mounting work is easy and not only does not stain the mounting place, but also the inner contact surface has a frictional resistance. The structure is large, so that it is difficult to remove even the curved part of the door.

Since the front end portion of the door edge protection material is easily deformed, by mounting it slightly protruding from the door edge, not only the door edge but also an object to be contacted is not damaged. The effect was seen.

[0019] By making the door edge protective material transparent, the door does not appear to be framed by the protective material no matter which body color the vehicle is attached to, and the design design of the vehicle without any discomfort is impaired. There was an effect of protecting the door edge without knowing.
