DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative molding for doors used for improving the design of doors.

[0002]

2. Description of the Related Art A conventional steel door is a decorative mall formed by using a material such as aluminum, brass, stainless steel, plastic, etc. which is given a single color such as a color coating in addition to a gold color or a bronze color. Attachment of members and members to the surface of a door has been carried out to improve the design of the door and to change the design.

[0003]

However, in the door having the conventional structure, since the decorative coating is applied to the surface of the decoration mall or the member, the surface of the door exposed to the outside may be damaged. When receiving or cleaning a dirty surface with a cleaning member, the coating film formed on the surface of the decoration mall or the member is damaged, and the design applied to the door is significantly damaged in a short period of time. Often.

[0004] The present invention has been made in view of these circumstances, and even when the surface of the door is damaged or cleaned by a cleaning member, the design of the decorative mall attached to the surface of the door is improved. Not to be damaged,
An object of the present invention is to provide a decorative mall for a door in which a design applied to a door is maintained in a good state for a long period of time.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above-mentioned object, and is a molding body attached to a door.
(2) and a cross-sectional shape provided on the surface of the molding body
Are inverted trapezoidal or rectangular grooves (3, 4) and the inner surface of said grooves
Decorative module consisting of a coating film (5) formed only on the whole
(1), wherein the groove has an unpainted side wall.
A coating film is formed so that no portion is generated .

[0006]

When the decorative mall for a door according to the present invention is mounted on a door, even if an object placed near the door or an object carried by the hand contacts the decorative mall on the door surface when the door is opened and closed, Since the coatings of various thicknesses formed in the grooves on the surface of the main body are not damaged by objects that come into contact with the door, the design of the decorative mall given to the door is maintained for a long time.

Further, when cleaning the surface of a dirty door with a cleaning member, the pressing force of the cleaning member pressed against the door does not act on the coatings of various thicknesses in the grooves provided on the surface of the molding body. Each of the coatings formed by means such as painting is prevented from being damaged when the door is cleaned. In addition, make sure that there is no unpainted part on the sidewall of the groove
Since the paint film is formed on the door, the decorative molding of the present invention gives an excellent design effect to the door.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1, 2, 3, 4 and 5 show an embodiment of the present invention.
And each groove 3, which is provided in the length direction and the width direction of the surface,
4 and a coating film 5 formed on the entire inner surface of each of the grooves 3 and 4.

As the material of the molding body 2, aluminum, brass, stainless steel, plastic or the like is used. The grooves 3 and 4 on the surface of the molding body 2 are formed in a required number in the length direction and in the width direction by using an extrusion mold or by machining such as a milling cutter. The groove 3 thus formed may be formed by processing the groove 4 by NC milling.

The cross-sectional shape of each of the grooves 3 and 4 in the length direction and the width direction is usually formed in an inverted trapezoid (see FIG. 2) or a rectangle (see FIG. 3). The angle of inclination of the inclined sides on both sides where the width dimension becomes narrower toward the groove is appropriately changed depending on the material used for the molding body 2 and the method of forming the grooves. In the case of a rectangular shape, the width of the grooves 3 is as shown in FIG. Does not change from to the groove bottom. The appropriate groove depth of each of the grooves 3 and 4 provided on the surface of the molding body 2 is limited to a range of 0.1 to 1 mm.

In this case, the lower limit of the groove depth of 0.1 mm is a practical minimum dimension which can be used to form a thin film 5 on the entire surface of each of the grooves 3 and 4 by means such as painting. It was decided.

On the other hand, when the upper limit of the groove depth is 1 mm, when the coating 5 is to be formed on the inner surfaces of the grooves 3 and 4 by coating, the paint applied to the side walls of the grooves 3 and 4 is It is determined from the necessity to prevent the paint sink (unpainted portion) from forming on the side wall and sinking to the side.

Each groove 3 provided on the surface of the molding body 2
Inside 4, a colored film 5 is formed by means such as painting. Therefore, such a coating 5 has a thickness of 0.1 to 1 mm.
When formed in each of the grooves 3 and 4 having a groove depth of
Regardless film 5 on whether the thick film or a thin film of the inner, since there is no possible to generate a coating aid in the side wall top, each groove 3 and 4, the entire inner surface tint paint used thus determined It is uniformly colored, and the product price of the decoration mall 1 is significantly increased.

FIG. 1, FIG. 2 and FIG. 3 show a case where the decorative molding 1 is elongated and long, in which two grooves 3 are provided in the length direction and a large number of grooves 4 are provided at intervals set in the width direction. Each is provided in parallel. When the width of the decorative molding 1 is about 9 mm and the thickness is about 3 mm, the widths of the grooves 3 and 4 are 1 mm on the upper surface side, 0.7 mm on the groove bottom side, and 0 on the groove depth. Although it is about 0.5 mm, it goes without saying that the dimensions of the decorative molding 1 and the grooves 3 and 4 may be set to other values.

The elongated and long decorative mall 1 includes a door 6
For example, the door 6 is attached to one or both of the height direction and the lateral direction in an arrangement as shown in FIG. 5 to give the door 6 a sense of quality and accent, and enhance the design effect given to the door 6.

FIGS. 6 and 7 show another embodiment of the present invention. The decorative molding 1A has a side of, for example, 40 mm.
And a plurality of grooves 3 orthogonal to each other in a diagonal direction on the surface of the molding body 2A.
A, 4A are provided at set intervals, and these grooves 3
The coating 5 is formed on the entire inner surfaces of the A and 4A in the same manner as in the above embodiment.
This is the case where A was formed. The width dimension of the grooves 3A, 4A is wider than that of the embodiment, and is set to, for example, about 2 mm.

The shape of the decorative molding 1A is not limited to a square, but may be any shape. Further, the arrangement, dimensions and crossing angles of the grooves 3A and 4A provided in the molding body 2A may be freely changed.

The plate-shaped decorative mall 1A is attached to the door 6 alone or in an array in which a plurality of decorative malls are set.
It is attached to the door 6 together with the long decorative mall 1 of the embodiment (see FIG. 7) to enhance the design effect given to the door 6.

[0019]

According to the present invention, even if an object comes into contact with the door to which the decorative mall is attached, the object only comes into contact with the surface of the decorative mall. The damaged coating is not damaged. For this reason, the life of the decorative mall becomes longer, and the design effect given to the door by the decorative mall can be maintained in a good state for a long period of time.

Also, when the cleaning member is pressed against the surface of the dirty door for cleaning, most of the pressing force of the cleaning member is received by the surface of the decorative molding, so that the film formed in the groove is not cleaned during cleaning. Damage can be prevented. Moreover , since paint scum does not occur on the upper part of the side wall of the groove, the finish of the film formed on the inner surface of the groove is improved, and not only can the commercial value of the decorative mall be increased,
The design effect given to the door can be improved.
