Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame material for fittings in which a three-dimensional pattern in which irregularities are repeatedly formed in the inner and outer directions and which is continuous in the extrusion direction is formed on a groove wall forming a glass fitting groove.

[0002]

2. Description of the Related Art As means for forming a three-dimensional pattern on the side wall of an extruded mold material, (a) by pressing a pressure roll or a press molding die engraved on the surface of the molded material after extrusion molding to form a predetermined score line or unevenness on the side wall. An embossing method for engraving and (b) a corrosion method for engraving the original image by etching with a chemical agent on the surface of the die material after extrusion molding using a photomechanical method can be considered. (For example, Japanese Utility Model Laid-Open No. 53-143881 and Japanese Patent Laid-Open No. 53-127872)

As disclosed in Japanese Patent Publication No. 56-4324, which was previously invented by the applicant, the outer surface forming land of the die is provided with a notch so that the length of the outer surface forming land is shorter than the length of the inner surface forming land, and the central portion of the side wall of the die material is cut. There are also known means for forming a three-dimensional pattern of horizontal stripes that is wavy in the extruding direction, and means for forming a crescent-shaped three-dimensional pattern in which the sides bulge in the extruding direction and the both sides bend in the opposite direction in the center of the side wall. ing.

[0004]

In the embossing method, the engraving die is strongly pressed against the side wall of the extruded mold material,
Since it has to be strongly pressed by the stamping die, it is effective for the flat side wall, but it is difficult to apply it to the curved side wall, and there is a problem that a lot of labor and cost are required for manufacturing the stamping die. Further, the corrosion method is troublesome and requires post-treatment. In addition, when both means are used, each requires a mechanical equipment separate from the extrusion molding machine, and there is a problem that it is difficult to use the extrusion molding material having a particularly complicated shape.

In Japanese Patent Publication No. 56-4324, which was previously invented by the applicant, a horizontal striped three-dimensional pattern having a wavy shape in the extruding direction at the center of the side wall of the mold, and a striped pattern in the extruding direction of the mold at the center of the side wall. It is possible to reveal a crescent-shaped three-dimensional pattern that bulges out and curves on both sides in opposite directions, but since there are few three-dimensional pattern patterns, it has become desirable to have a three-dimensional pattern with a high decorative effect. Then, this invention develops the idea of Japanese Patent Publication No. 56-4324 which the applicant previously invented, and provides the frame material for fittings which shows a three-dimensional pattern stably.

[0006]

In order to achieve the above object, the frame material for fittings of the present invention has an inner groove wall and an outer groove wall which form a glass fitting groove, and is provided between the inner piece and the outer piece. It is formed into a double wall structure with a hollow part, and the outer strip is provided with uneven strips parallel to the longitudinal direction of the frame material on both sides, and the thickness of the outer strip between the uneven strips is made thinner than the normal wall thickness. This is a three-dimensional pattern in which irregularities are repeatedly formed in the inner and outer directions on one side and which is continuous in the extrusion direction without secondary processing.

The auxiliary frame member 5 is fitted and locked to the outer periphery of the vertical frame member 12 as shown in FIG.

Next, the frame material for joinery of the present invention is shown in FIGS.
When the normal wall forming land N and the outer piece forming land n are formed on the male mold d1 and the female mold d2 that form the die D as shown in 3, the gap M between the normal wall forming lands N is adjusted to the normal wall thickness T, The gap m of the outer piece forming land n is formed to match the outer piece thickness t, and the flow resistance of the metal passing through the outer piece forming land n is significantly smaller than the flow resistance of the metal passing through the normal wall forming land N. So that, for example, at the rear part of the outer piece forming land n, an escape port E that is inclined and opened in a wide mouth toward the extrusion direction,
A guide port G is formed in the front portion so as to widen and incline toward the front, and the outer piece forming land length h is shorter than the normal wall forming land length H.

At the rear part of the outer piece forming land n, there is an escape port E which is inclined and wide toward the extrusion direction, and a guide port G which is inclined and wide toward the front toward the front, for example, an inclination angle of 30 degrees. And the land length h of the outer piece 2b is set to the inner piece 2a or the uneven strip.
It is shorter than the normal wall forming land length H of 7a. The escape E is formed in the die female die d2 and the guide opening G is formed in the die male die d1, or conversely, the escape E is formed in the die male die d1 and the guide opening G is formed in the die female die d2. It is desirable to form the mouth E and the guide opening G in a staggered manner.

When the frame material for fittings of the present invention is extruded using the die D, the normal wall forming lands N and the outer piece forming lands n provided in the die D have different metal flow resistances. Difference in the flow of metal through the
The outer piece 2b extruded from the outer piece forming land n due to the difference
Then, the unevenness is repeated in the inner and outer directions of the frame material 1, and the three-dimensional pattern 7 continuous in the extrusion direction naturally appears.

The cause of the appearance of the three-dimensional pattern 7 has not been completely clarified yet, but when the land lengths H and h of the normal wall forming land N and the outer piece forming land n are variously changed, an experiment is conducted. When the land lengths H and h were set to be the same in the state where the extrusion speed was constant (all the lands of the conventional die were formed to have the same length), a mold material having a smooth wall surface was obtained.

[0018]

Since the frame material for fittings according to the present invention is as described above, it has the following effects. Since the glass fitting groove is projected to the inner peripheral side from the main wall of the frame material, and the inner groove wall and the outer groove wall are formed into a double wall structure having a hollow portion between the inner piece and the outer piece. , The heat insulation effect of the inner and outer groove walls is improved, and the durability is also improved. Moreover, since the three-dimensional pattern appears on the outer pieces of the inner and outer groove walls, the three-dimensional pattern causes light to be slightly irregularly reflected, creating a dignified and beautiful aesthetic that cannot be represented by printing or coloring. As a result, it is useful as a frame material for fittings for show windows and store fronts that require decoration.

The thickness of the outer piece of the inner / outer groove wall is made thinner than that of the normal wall so that the flow resistance of the metal passing through the outer piece forming land is significantly smaller than the flow resistance of the metal passing through the normal wall forming land. Since the pattern is continuously exposed by extrusion molding, chemical treatment or mechanical secondary processing is not required to reveal the three-dimensional pattern. As a result, it is possible to manufacture the frame material for joinery, which has a three-dimensional pattern, significantly easier and easier than the conventional one.
