[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover for covering an edge portion of an edge portion of a plate body, such as a door edge which is an edge portion of a plate member formed in a fin shape at an edge portion of a door panel of an automobile or an automobile body. It is related to a mall that can be attached to the mall.

[0002]

2. Description of the Related Art For example, at the edge of a door panel of an automobile, there is a door edge which is a thin plate (plate) having a thickness of about several mm and protrudes in a fin shape. Damaged by impact, or conversely,
Since it is a part which is liable to cause inconvenience such as damaging an article colliding with the door edge, a molding (door edge molding) is provided on the door edge in order to prevent these inconveniences.
May be attached. The molding is a flexible linear body formed of a synthetic resin such as vinyl chloride or polycarbonate, and is fixed to the door panel using a double-sided adhesive tape or an adhesive, so that the edge of the edge of the door edge is formed. It is common to mount it so as to cover the part or to install it on the outer surface of the door edge. By attaching the molding, the edge portion is protected, so that damage, deformation, peeling of the paint, and the like can be prevented, and damage to the article colliding with the edge portion can also be prevented. In addition, a decoration layer is often formed on the outer surface of the molding by vapor deposition, painting, bonding, or the like. In this case, the molding also functions as a decoration material.

[0003] A conventional example of a door edge molding for an automobile belonging to this will be described below with reference to FIGS. The door edge molding 1 shown in FIG. 4 is a flexible linear body having a semicylindrical cross section (a cross section slightly flatter than a semicircle), and has a flat bottom surface near the edge 4b of the edge of the door edge 4. 2
Is adhered and fixed to the outer surface 4a side of the door edge 4 by the double-sided adhesive tape 3. Door edge molding 5 shown in FIG.
Is a flexible linear body having a U-shaped cross section, and stores the edge portion 4b in the inner edge portion storing groove 6;
The inner surface of the edge storage groove 6 is bonded and fixed to the door edge 4 near the edge 4b with the double-sided adhesive tape 3. The door edge molding 7 shown in FIG. 6 has a cross section including a main body 7a having a semicylindrical cross section (a cross section slightly flatter than a semicircle) and a protective wall portion 7b protruding from one side of the main body 7a. It is an L-shaped flexible linear body, and is attached to the vicinity of the edge portion 4b by bonding and fixing the flat bottom surface 7c of the main body portion 7a to the outer surface 4a side of the door 4 with the double-sided adhesive tape 3. I have. The protection wall portion 7b is connected to the edge portion 4b.
It is arranged so as to cover the tip. Each of the door edge moldings 1, 5, and 7 has a decorative layer formed on the outer surface side of the door edge 4 (the outer surface of a portion exposed to the upper side in FIGS. 4, 5, and 6) by vapor deposition, painting, bonding, or the like. Sometimes.

[0004]

However, since the above-mentioned door edge molding is firmly fixed to the edge of the door with a double-sided adhesive tape or an adhesive, it is not easy to peel off once pasted. In particular, in the case of fixing using an adhesive, if it is forcibly peeled off, there is a possibility that the paint on the door is peeled off together, or even if the paint on the door is not peeled off, it may be damaged. For this reason,
It was very difficult to replace the door edge mall. Also, when fixed with double-sided adhesive tape,
There is a disadvantage that the fixing force is reduced due to the deterioration of the double-sided adhesive tape over time. Furthermore, no matter whether an adhesive or a double-sided adhesive tape is used, sand and dust are likely to be clogged between the car body (door) and the molding. In some cases, detergents and waxes are clogged and the appearance is impaired. The above-described problem is not limited to the door edge molding. For example, a molding attached to cover an edge portion of an openable door-like panel material provided on a hood or a trunk of an automobile, an edge on a body side, or the like. The same applies to a mall attached to cover an edge portion of various panel materials existing in an automobile, such as a mall attached to cover a portion thereof. Further, the present invention is not limited to automobiles, and forms a mall applied to an edge portion of various panel materials such as a door panel of a four-wheeled vehicle that travels by hand, and a so-called trailer house door panel or various doors towed by an automobile or the like. The same applies to the mall applied to the panel material, and also to the mall applied to the edge portion of the plate body existing in the building materials and various facilities installed indoors.
A mall that can improve the cleaning workability has been demanded.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and is easily attached by magnetic attraction to an edge portion of a panel material made of a material capable of being magnetically attracted by a molding body containing a magnet. It is an object of the present invention to provide a mall that can be attached and detached, and as a result, is excellent in workability of replacement and cleaning, and can easily maintain an aesthetic appearance.

[0006]

SUMMARY OF THE INVENTION The present invention is directed to a molding which is attached so as to cover an edge existing at an edge of a plate, wherein the molding is made of a resin molding which is a flexible linear body. Further, a molding characterized by dispersing magnets in the form of particles, needles, plates, or the like is used as a means for solving the above-mentioned problem. The molding of the present invention is an edge of a plate having a magnetic material, that is, an edge of a plate made of a magnetic material such as an iron plate, an edge of a plate provided with a magnetic material by adhesion, mixing, or the like, It is attached by the magnetic attraction of a magnet provided in the molding body. The magnetic attraction force of the magnet is preferably such that the molding can be manually removed from the plate body, whereby the molding can be easily attached to and detached from the edge of the plate body. The molding body may have various cross-sectional shapes. As described in claim 2, the edge portion receiving groove into which the edge portion is inserted is opened at a side portion of the molding body over substantially the entire length in the longitudinal direction of the molding body. More preferably, it is performed.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a mall according to the present invention will be described below. The molding body is made of a non-magnetic resin such as a synthetic resin such as vinyl chloride or polycarbonate, or a natural resin such as natural rubber, and is a flexible linear body. The magnet dispersed in the molding body is a permanent magnet, for example, granular, needle-like, or plate-like powder made of iron, iron-cobalt alloy, or the like. Magnets in the form of granules, needles, or plates (hereinafter sometimes referred to as “magnetic powders”) are more likely to disperse and mix in the resin of the molding body by orienting the magnetic poles. The point to obtain strong magnetic attraction,
Alternatively, it is preferable in that the desired magnetic attraction force can be stably obtained.
When the contact surface to be in contact with the plate body is formed on the side surface of the molding body, and the same pole of each magnetic powder is aligned on this contact surface side (orientation), the contact surface side and the opposite side of the molding body as a whole as well. To give the opposite polarity.

As an example of a method for manufacturing the molding body, a magnetic powder, which is a granular, needle-like or plate-like powder, is mixed and stirred into a molten resin, and the mixture is extruded and molded and cured. The magnet is magnetized by applying a strong magnetic force after molding of the resin, before curing, or after curing. As a result, the magnetic powder becomes a permanent magnet, and the entire molding also functions as a magnet (so-called bonded magnet). For example, after performing magnetic field orientation treatment in any process from the middle of molding of resin mixed with magnetic powder such as needle-like particles or hexagonal plate-like particles to before curing, and magnetizing, the entire molding is anisotropic magnet Can function as In addition, for example, when magnetic powder such as spherical particles is used, and magnetized after molding into a molding without performing a magnetic field orientation treatment, the entire molding can easily function as an isotropic magnet. In the case of this isotropic magnet, it is possible to mold a resin mixed with magnetized magnetic powder, but since there is a possibility that the magnetic powder is magnetically attracted to the molding device, in this respect, the It is preferable to magnetize after molding the resin mixed with the magnetic powder.

The magnetic particles of the spherical particles have a diameter of about several tens to several hundreds μm, and plate-like particles such as hexagonal plates and needle-like particles having a maximum dimension of about several tens to several hundreds μm are to be employed. Preferably, the flexibility of the molding can be easily ensured, and the molding can be continuously and evenly attached to a curved portion such as a door edge of an automobile or an edge portion of a bonnet. Deposition, painting, on the outer surface of the mall body other than the contact surface
The decorative layer may be formed by film bonding or the like, but in this case, needless to say, the flexibility of the entire molding is ensured. Further, since the molding is used by appropriately cutting it according to the length of the edge portion to be attached, it is preferable that the molding can be easily cut with hand tools such as scissors.

The magnetic attraction of the molding body to the plate to be attached is preferably such that the molding can be manually removed from the plate, so that the molding can be easily attached to and detached from the edge of the plate. it can. Further, inconveniences such as adversely affecting the painting of the surface of the plate body during removal can be prevented. Adhesives and double-sided adhesive tapes are not used to attach the mall to the plate, so even if the mall is removed from the plate, no adhesive or double-sided adhesive tape remains on the plate. There is no need for an operation to remove the odor. If the molding can be easily attached to and detached from the edge portion, for example, it is possible to extremely easily replace a molding that has deteriorated over time or a molding that has been damaged by an external impact or the like.

[0011] In a motor vehicle, objects to be attached to the mall exist at door edges, bonnet edges, trunk door edges, and the like. These door edges, bonnet edges,
In many cases, fin-shaped portions (plates) formed from thin plates (steel plates) each having a thickness of several mm or 1 mm or less exist at the edges of the trunk doors. An edge portion which is an edge portion of the plate body is a mounting target of the molding. Doors, hoods, trunk doors, etc.
Both are usually formed using a steel plate, and are usually magnetic materials capable of magnetic attraction. The molding according to the present invention is detachably attached to the edge portion made of a magnetic material by magnetic attraction. Therefore, at the time of washing a car, for example, by removing the molding from the edge, the edge and the molding can be easily cleaned, and sand and dust accumulated in a gap between the edge and the molding can be easily removed. In addition, if the molding is removed, there is no inconvenience that the detergent or wax accumulates in the gap between the edge portion and the molding, so that the car can be washed very efficiently and the appearance of the automobile can be maintained.

When the edge receiving groove into which the edge of the plate is inserted is formed over substantially the entire length in the longitudinal direction of the molding body, the edge portion is received in the edge receiving groove so that the contact resistance is reduced. Not only does it make it difficult for the molding to slip out of the edge and to displace,
The magnetic attraction area between the edge portion and the molding increases, and a stronger magnetic attraction force can be secured. Car door edges,
When applied to the edge of a bonnet, the edge of a door of a trunk, or the like, it is possible to prevent the mall from slipping out or displacing due to vibration, wind pressure, or the like caused by running of an automobile, in addition to human contact. In addition, since the molding bodies on both sides of the edge storage groove are almost in close contact with the plate body due to the magnetic attraction force, and the formation of a gap is suppressed,
The clogging of sand and dust can be greatly reduced.

Hereinafter, an embodiment of a mall according to the present invention will be described in detail with reference to FIGS. In addition, the first
The third to third embodiments are all examples of application to the edge (edge) of a door edge of an automobile. The door edge is a plate edge protruding in a fin shape from an edge of an automobile door panel, and the plate is made of a steel plate as a magnetic material capable of being magnetically attracted.
