Abstract

PURPOSE:To prevent the intrusion of the slit wind and the harmful insects by integrally forming the engagement part between a basic part and a shutter slat by using the hard synthetic resin and forming a contact body by using the soft synthetic resin, simultaneously with the molding of the basic part, by using an extrusion molding machine. CONSTITUTION:A basic part 2 and the engagement parts 3 and 3 which can be engaged with a shutter slat 6 are integrally extrusion-molded by using the hard synthetic resin, and the contact bodies 4 and 4 having a nearly 'truncated chevron' shaped section are integrally molded at the lower left and right end parts of the basic part 2 by an extrusion molding machine simultaneously with the molding of the basic part 2 by using the soft synthetic resin. Then, on the undersurfaces of the contact bodies 4 and 4 having the truncated chevron shaped section. auxiliary contact bodies 5 and 5 are integrally molded by using the soft synthetic resin. When the engagement part 6A of the shutter slat 6 is engaged with the engagement parts 3 and 3, and the shutter is closed the contact bodies set 4 and 4 make contact with an edge member 7, having the top end parts in each curved form, since the contact bodies 4 and 4 are soft, while if the width of the edge member 7 is narrow, the contact bodies 4 and 4 make contact so as to cover the edge member 7. Even if the shutter is inclined for the advance direction, the whole surface contact within a range of the bending due to each flexibility of the contact bodies 4 and 4 is enabled.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shutter head end material, and more particularly to a shutter head end material capable of closely contacting a facing edge member over the entire longitudinal length of the shutter head end material connected to a plurality of shutter slats. .

[0002]

2. Description of the Related Art Conventionally, this main shutter has been used, for example, on a window or entrance of a building, or on the front surface of a warm and cold storage case, and the like. It is either a structure that closes the mouth or a structure that slides to the left and right.

[0003]

The conventional shutter has a metal, plastic, or cloth-shaped main body with a plastic head end member attached thereto. As a result, when the shutter is closed, the edge material facing the head end material is hard, and in the case where multiple shutter slats are connected, there is a play gap in the connection part, so when closing the head There was a problem that the mill ends were inclined with respect to the straight running direction to form a gap. In order to solve that, on the tip surface of the head end material,
A rubber tube-shaped seal material is also known, but since the tube-shaped seal material is hollow, it has a bulge unless it is crushed until the hollow part disappears. If the end material is long (when the width of the shutter is wide), even if one end is in close contact with the edge material, the other end may be raised due to the elasticity of the tube-shaped seal material. Yes, there was a drawback that we could not get close. In view of these circumstances, the present invention was developed for the purpose of providing a shutter head end material in which the head end material easily comes into close contact with the edge member.

[0004]

The present invention has taken the following technical means in order to solve the above problems and achieve the objects. That is,

A. An engaging portion of the shutter slat is formed on an upper portion of the base of the head end material, and the base and the engaging portion are integrally formed of a hard synthetic resin material.

B. Contact bodies having a substantially eight-shaped cross section were formed integrally with an extruding machine at the same time when the base was molded at the right and left ends of the base with a soft synthetic resin material.

C. In addition, an auxiliary contact body was formed on the lower surface of the substantially 8-shaped contact body as required.

[0008]

The present invention constructed as described above operates as follows. That is, the hard engaging portion can be connected by engaging with the engaging portion of the shutter slat. When this shutter is closed, the approximately 8-shaped contact body comes into contact with the facing edge material, but even if the head end material is inclined with respect to the traveling direction, the approximately 8-shaped contact body is soft and elastic. Therefore, the tip portion lays down and spreads in the portion that strongly contacts the edging material, and the tip portion does not lie so much in the weakly contacting portion, so that the entire length of the head end material comes into contact with the edging material.

[0009]

Embodiments of the present invention will be described with reference to the drawings. In FIG. 1, the shutter head end material 1 has an engaging portion 3.3 that is engageable with the shutter slat 6 formed on an upper portion of a base portion 2. The base portion 2 and the engaging portion 3.3 are made of a hard composite material. resin,
For example, it is integrally formed of hard vinyl chloride by extrusion molding. At the lower left and right ends of the base 2, a substantially synthetic resin material having a substantially eight-shaped cross-section with a lower end diverging,
For example, soft vinyl chloride is integrally molded by an extrusion molding machine when the base 2 is molded. In this case, the mold in which the base portion 2 and the engaging portion 3.3 are integrated and the mold for the contact body 4.4 are combined, and the former is made of hard vinyl chloride melted at around 200 ° C. Extruded, 150 for the latter
When the soft vinyl chloride melted at around ° C is extruded, the moldings extruded from both molds coalesce, and the soft material moldings are heated at the contact parts by the high temperature of the hard moldings to temporarily When it is extruded from the mold to the outside and cooled by the outside air, it adheres firmly and integrally. Therefore, peeling or the like does not occur. The engagement portion 6A of the shutter slat 6 is engaged with the engagement portion 3.3 of the head end material thus formed. Then, when the shutter is closed, as shown in FIG. 2, since the contact body 4.4 is flexible, the tip end is bent and comes into contact with the edge member 7. As a result, even if the shutter is inclined with respect to the traveling direction, the entire surface can be contacted within the range of bending due to the flexibility of the contact body 4.4. That is, FIG.
If the height of the contact body 4.4 is 15 mm, then 1 to 13
The difference due to the inclination of millimeter can be covered.

When the width of the edge member is narrow, the contact body 4.4 contacts the edge member 7 so as to cover the edge member 7, as shown in FIG.

FIG. 4 shows a shutter head end material 1 showing a second embodiment. This embodiment is characterized in that an auxiliary contact body 5.5 is formed on the lower surface of the contact body 4.4 with the same material as the contact body 4.4. The auxiliary contact body 5.5 is formed symmetrically toward the center, has a slope from the outside to the center, and has a thickness smaller than that of the contact body 4.4. In this embodiment, as shown in FIG. 5, even when the width of the edge member is extremely narrow, the auxiliary contact body 5.5 comes into contact with the edge member 7 to obtain a sealing effect.

FIG. 6 shows a shutter head end material 1 showing a third embodiment. In this embodiment, the auxiliary contact body 5.5 is formed in double, and the width of the edge member 7 can be widened or narrowed. The present invention is not limited to the above-mentioned shape, and the engaging portion is adapted to the shutter-side engaging portion that engages with the engaging portion. In addition, the contact body 4. The shape of can also be reversed as shown in FIG.

[0013]

As described above in detail, the present invention has the following excellent effects.

A. Since the contact member made of a soft material is integrally formed with the head end material, even if the shutter slat is inclined with respect to the traveling direction when the shutter is closed, the edge member can be brought into contact with the entire tip portion. This is effective in preventing the entry of drafts and harmful insects.

B. Since the contact body is formed in an inclined shape with respect to the moving direction of the shutter, the soft contact body can make contact in accordance with the difference in width of the mating edge member, which has the effect of widening the application. .

C. Since it can also be used for various shutters such as building entrance shutters, window shutters, furniture shutters, product case shutters, etc. Has the effect of improving.
