Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art In conventional steel doors, in addition to gold color and bronze color, decorative moldings made of materials such as aluminum, brass, stainless steel, plastic, etc. which are single-colored such as color painting By attaching a member or a member to the surface of the door, the design of the door has been improved or the design has been changed.

[0003]

However, in the door having the conventional structure, the surface of the door exposed to the outside is damaged because the surface of the decorative molding or the member is painted or decorated for decoration. When receiving or cleaning a dirty surface with a cleaning member, the paint or dye coating formed on the surface of the decorative molding or the member is damaged, and the design applied to the door takes a relatively short time. Often severely damaged.

The present invention has been made in view of these circumstances. Even when the surface of a door is damaged by scratches or is cleaned by a cleaning member, the decorative mall attached to the surface of the door has a good design. Not to be damaged,
It is an object of the present invention to provide a decorative molding for a door in which the design applied to the door is kept in a good condition for a long period of time.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above-mentioned object, and a molding body mounted on a door has a groove having a depth of 0.1 to 1 mm on the surface of a mold or a machine. A door decoration characterized in that a film, which is a thin film or a thick film depending on its depth, is formed by means of painting, dyeing or the like in the groove provided by processing and provided on the surface of the molding body. It is the inventor of the mall.

[0006]

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

Further, when cleaning a dirty door surface 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 groove provided on the surface of the molding body. The respective coatings formed by means such as painting and dyeing are prevented from being damaged when the door is cleaned. Moreover, since the depth of the groove formed on the surface of the molding body is 1 mm or less, when a thick film is formed in the groove, it is possible to prevent the occurrence of paint marks that easily occur on the upper part of the groove, The decorative molding gives the door an excellent design effect.

[0008]

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

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

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). In the case of an inverted trapezoid, the groove bottom is as shown in FIG. The inclination angles of the inclined sides on both sides in which the width becomes narrower are appropriately changed depending on the material used for the molding body 2 and the method of forming the groove. In the case of a rectangle, the width of the groove 3 is the upper portion of the groove as shown in FIG. It does not change from the bottom to the bottom of the groove. The appropriate groove depth of the grooves 3 and 4 provided on the surface of the molding body 2 is limited to the range of 0.1 to 1 mm.

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

On the other hand, the upper limit of the groove depth of 1 mm is such that when the coating 5 is to be formed on the inner surfaces of the grooves 3 and 4 by coating, the coating material applied to the side walls of the grooves 3 and 4 is the bottom of the groove. It was decided from the necessity to prevent the paint sunk (unpainted part) from being generated on the upper side wall by sinking to the side.

Each groove 3, provided on the surface of the molding body 2,
A coating film 5 colored by a means such as painting or dyeing is formed in the interior of 4. Therefore, such a coating 5 is 0.1 to
When it is formed in each groove 3 and 4 having a groove depth of 1 mm, regardless of whether the coating film 5 in each groove 3 and 4 is a thin film or a thick film, a paint skein is generated on the upper side wall. Since the grooves 3 and 4 are uniformly colored on the entire inner surface in a shade determined by the used paint or dyeing, the commodity price of the decorative molding 1 is significantly increased.

FIGS. 1, 2 and 3 show a case in which the decoration molding 1 is a long and slender one, and two grooves 3 in the length direction and a large number of grooves 4 at intervals set in the width direction, They are provided in parallel. Regarding the dimensions of the grooves 3 and 4, when the width of the decorative molding 1 is 9 mm and the thickness is about 3 mm, the width dimension on the upper surface side is 1 mm, the width dimension on the groove bottom side is 0.7 mm, and the groove depth is 0. .5
Although it is about mm, the dimensions of the decorative molding 1 and the grooves 3 and 4 are
Of course, other values may be set.

The long and slender decorative mall 1 has a door 6
Are attached in one or both of the height direction and the lateral direction in an arrangement as shown in FIG. 5, for example, to give the door 6 a high-class feeling 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 square plate shape with one side of, for example, about 40 mm, and is in a diagonal direction on the surface of the molding main body 2A. , A plurality of grooves 3A, which are orthogonal to each other,
4A are provided at set intervals, and these grooves 3A,
This is a case where the coating 5A is formed on the entire inner surface of 4A as in the case of the above embodiment. The width of the grooves 3A and 4A is wider than that in the above embodiment, and is set to, for example, about 2 mm.

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

The plate-shaped decorative molding 1A is attached to the door 6 alone or in an array in which plural pieces are set,
It is attached to the door 6 together with the elongated decorative molding 1 of the above embodiment (see FIG. 7) to enhance the design effect given to the door 6.

[0019]

According to the present invention, the following excellent operational effects can be obtained.

In the decorative molding for doors according to claim 1, a depth of 0.1 to 1 mm provided on the surface of the molding body.
Since a film is formed in the groove of the decoration by means such as painting or dyeing, even if an object comes into contact with the door with the decorative molding of this configuration, the object only contacts the surface of the decorative molding. Therefore, the coating formed in the groove on the surface of the molding body is not damaged. Therefore, the life of the decorative molding is extended, and the design effect given to the door by the decorative molding can be maintained in a good state for a long time.

Further, even 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 cleaned at the time of cleaning. It can be prevented from being damaged. Moreover, the depth of the groove formed in the molding body is 0.
Since the size is determined within the range of 1 to 1 mm so that paint bleeding does not occur on the upper side wall of the groove, the finish of the film formed on the inner surface of the groove can be improved and the commercial value of the decorative molding can be increased. The design effect given to the door can be improved.
