Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin edging material. The edge-attachment material is applied over the entire surface of the wood to improve the appearance, in order to hide the ugliness of the wood such as housing equipment and furniture made of plywood or laminated wood.

[0002]

2. Description of the Related Art Bordering materials made of synthetic resin are known. Since the edging material is for hiding the ugliness of the wood surface, its size is large enough to cover the entire wood surface, and its surface is neat and beautiful, reminiscent of the surface cut with a plane. The surface is often printed with a wood grain pattern. Also, the thickness is usually 0.5 mm
Use a uniform wall thickness.

On the other hand, a packing material is similar to the edge pasting material. The packing material is, for example, to fill a naturally occurring gap between the pillar and the sliding door to prevent the entry of wind and noise, and to be attached to keep the room warm. In addition, it is attached to fill the gap between the door and the hanging door of the cupboard or sink to prevent the entry of cockroaches and other insects and to reduce the noise when the door is closed. Is. The packing material was often made entirely of soft synthetic resin,
Some of them were made by combining a hard synthetic resin and a soft synthetic resin.

FIG. 1 shows a conventional pillar and sliding door provided with a packing material together with a synthetic resin pillar covering material.
In FIG. 1, the pillar covering material A is attached to the outside of the pillar P, and the packing material B is attached to a part of the pillar against which the sliding door C collides. The pillar covering material A is made entirely of hard synthetic resin.
The packing material B is made of a hard synthetic resin and a soft synthetic resin, the portion B ₁ flush with the pillar covering material A is made of a hard resin, and the remaining portion B ₂ is made of a soft resin. . The base portion of the soft portion B ₂ is inserted into the pillar P, the tip of the soft portion B ₂ is projected from the pillar covering material A, and then the soft portion B ₂ is bent outward in an arc shape and is oriented parallel to the pillar covering material A. The arcuate portion bends due to the collision of the sliding door C and comes into close contact with the pillar covering material A, thereby closing the gap between the pillar P and the sliding door C. By the way, in many cases, the edge sticking material is used for the portion C ₁ where the arcuate portion B ₂ attached to the pillar collides with the sliding door C.

FIG. 2 shows a conventional pillar and hinged door provided with a packing material together with a synthetic resin pillar covering material.
In FIG. 2, a pillar covering material A is attached to the pillar P, and a door contact material B with a packing material is attached to a portion in contact with the hinged door E on the pillar P side. The pillar covering material A is made of hard synthetic resin, and the door contact material B with packing material is made of hard synthetic resin and soft synthetic resin. More specifically, in the door contact member B with packing material, the portion B ₂ having an arcuate cross section that contacts the hinged door E is made of soft synthetic resin, but the remaining portion B ₁ is made of hard synthetic resin. There is. In the normal state (when the hinged door is open), the soft portion B ₂ largely projects toward the hinged door E, but when it is pushed by the hinged door E, it deforms and comes into close contact with the surface of the hinged door E. The gap between the hinged door E and the hinged door E is closed, and it also serves as a muffler when the hinged door E is closed. Incidentally, the edging material is often used for E ₁ .

FIG. 3 shows a pillar P to which a synthetic resin pillar covering material A is attached and a sliding door C to which a packing material B is attached. In FIG. 3, the edge patch material C ₁ is provided on the surface of the sliding door C facing the pillar P, and the packing material B is provided thereon. In the packing material B, the substrate B ₁ is made of a hard synthetic resin, and the raised portion B ₂ is made of a soft synthetic resin.

As described above, the synthetic resin edging material and the synthetic resin packing material have been manufactured separately. The packing material was attached to the pillar side, to the sliding door side, or to the hanging door side of the sink, but all of them involve manual work, which hinders productivity improvement, and most of them have adhesive. Although it is attached with double-sided tape, there are problems that it peels off after use, and the position to paste is not uniform due to manual work, which impairs aesthetics. In addition, since the packing material has the side edge of the soft synthetic resin strip with an arc-shaped cross section fixed to the side surface by the upper surface of the hard substrate, the soft strip is formed when the space between the pillar and the sliding door is wide. Not only does the body greatly protrude from the board and deteriorate the appearance, but even if the packing material fills the gap that naturally occurs when the pillar and the sliding door are closed, there is no groove for the packing material to be stored. There was a problem that it looked as if there was a gap in the sliding door. In addition, it is convenient to use a roll-shaped roll to take up the material more efficiently and to reduce the packing size during transportation, but it is inconvenient to make it into a roll because the soft strip is protruding. . .

[0008]

SUMMARY OF THE INVENTION The present invention is intended to solve the above problems. Synthetic resin edging material and synthetic resin packing material are integrated to provide a synthetic resin edging material with a packing material having grooves on the substrate,
By attaching this with an automatic edge pasting machine, it aims to provide an article with an aesthetically pleasing appearance in which the edge sticking and packing properties can be obtained at the same time without the need for manual processing.

It is suitable to be in the range of up to 7.0 mm, and the width y
Is suitably in the range 1.5 to 30 mm. On the other hand, the soft synthetic resin strip 2 has flexible elasticity and has a thickness of 1. so that it always fills this gap, no matter how the gap between the pillar and the sliding door changes. 5 mm
It is suitable that it is below, and that the height z at which the tip of the middle height portion projects from the surface of the substrate 1 is within the range of 0.3 to 10 mm. Further, when the pillar and the sliding door are in close contact with each other, the strip-shaped body 2 has to be buried in the groove 11, so that a protruding portion is provided between the back surface 24 of the projecting middle-high portion 23 of the strip-shaped body 2 and the groove bottom 12. It is suitable to have a cavity 3 with a width and height greater than the width w and the height z.

The depth x in the strip substrate 1 is 0.3-.
It is desirable to be in the range of 1.0 to 2.5 mm among 7.0 mm, and the width y is 3.
The width y is preferably within the range of 0 to 9.0 mm, and the width y is preferably within the range of 1.2 to 9.0 even if 0.2 to 100 times the depth x. Further, the thickness of the soft strip 2 is preferably within the range of 0.5 to 0.2 mm even if it is 1.5 mm or less, and the protrusion height z is 0.3 to 10 mm.
Among them, it is desirable to be in the range of 2.0 to 5.0 mm, and the height of the cavity 3 is desirably 1.5 to 2.5 times the height z. Further, the soft synthetic resin forming the soft strip 2 is 23 ° C. according to the method of JIS K7215.
The hardness is about 25 to 23 when measured with a rubber hardness D type, whereas the hardness of the hard synthetic resin forming the substrate 1 is 74 to 7
7 with a hardness difference of at least about 49 therebetween.

Although the groove 11 is provided in the center of the substrate 1 in the width direction in FIGS. 4 and 5, the position where the groove 11 is provided is not limited to this. As shown in FIG. 6, the groove 11 may be provided outside the center of the substrate 1 in the width direction. Also groove 1
The cross-sectional shape of 1 is required to be constant, but the shape is not limited to a right-angled quadrangle, and may be a trapezoid that opens upward as shown in FIG.

The relationship between the groove 11 provided on the strip substrate 1 and the soft strip 2 is not limited to that shown in FIGS. 4 to 6. The relationship may be as shown in the cross section of FIG. That is, as shown in FIG.
The soft strip 2 may be a tube and may be fixed inside the groove 11 by the portion 4, and as shown in FIG. 7 (b), the soft strip 2 has an M-shaped cross section. In addition, the wall thickness is small at the protruding portion at the center and increases as it approaches both side edges.

It is desirable that the surface 13 having openings are flat, but the surface 13 may have small irregularities, and the back surface 14 of the strip substrate 1 may have a slight warp of medium height. For example, as shown in the transverse cross section of FIG. 8A, the front surface 13 of the substrate 1 may be an uneven surface having many small stripes extending in the longitudinal direction, and the back surface 14 of the substrate 1 may be a straight line F. The center of the width direction is higher than the straight line F by h
However, it may be slightly raised. However, on the contrary, as shown in FIG. 8B, when the back surface 14 of the substrate 1 contacts the straight line F, it is more preferable that both ends in the width direction do not float up. In the case of h, the width is preferably 1.5% or less. This is because it is preferable to eliminate the gap between the edge surface and the edge pasting material when applying the forehead.

Hard vinyl chloride resin, ABS resin (acrylonitrile / butadiene / styrene copolymer), polypropylene or the like can be used as the hard synthetic resin forming the substrate 1, and soft resin is used as the resin forming the soft strip 2. Vinyl chloride resin, low density polyethylene, sunplane (manufactured by Mitsui Petrochemical Co., Ltd.) and the like can be used. An adhesive may be used to bond the substrate 1 and the soft strip 2 to each other. However, as a resin constituting these, a resin of the same system, for example, a hard vinyl chloride resin is used for the substrate 1 and a soft vinyl chloride resin is striped. When used for the body 2, they can be bonded simply by heating and melting them.

To use the edging material according to the present invention, for example, as shown in FIG. 9, a back surface 14 of the substrate 1 is preliminarily coated with a primer, and a hot-melt type adhesive is automatically applied to the rim. It is applied automatically by a machine, and is used by pressing and adhering it to the mouth surface of the sliding door C with a roller of an automatic rimming machine. When the edge patch is pressure-bonded to the sliding door C, the edge patch protruding from the front surface of the sliding door is trimmed and used at the same time. In the edge pasting material according to the present invention, the soft strip 2 projects from the substrate 1 when it is not in contact with the pillar P, but when it is pushed in contact with the pillar P, the soft strip 2 like the sliding door D. Is pressed into the substrate 1 and the pillar P
The space between the substrate and the substrate 1 is completely closed. The appearance of the finished product is almost the same as that obtained by pasting a conventional edge adhesive material, and a packing effect can be obtained.

[0021]

According to the present invention, since the synthetic resin edging material is made of a hard synthetic resin band-shaped substrate and a soft synthetic resin band-shaped body having a middle and high cross section, this edging material is used. Can be easily manufactured by an extrusion molding method of a synthetic resin. In addition, this edge pasting material is provided with a groove penetrating in the longitudinal direction on the surface of the substrate, and the cross-sectional area of the groove is equal to or larger than the cross-sectional area of the soft strip, and the soft synthetic resin The strip-shaped body has its side edges fixed in the groove to project the middle height portion from the substrate surface, and between the strip-shaped body and the groove bottom has a size larger than the cross-sectional area of the strip-shaped body protruding from the substrate surface. Since the cavity is provided, when the flat surface of the pillar or sliding door approaches the surface of this edge pasting material, the flat surface first comes into contact with the mid-height portion of the soft strip, and then presses the mid-height portion to form the groove in the soft strip. It is pushed in and finally touches the substrate surface and stops. Therefore, a space between the flat surface and the edge pasting material is filled with the projecting soft strip, and the gap between the column and the sliding door is completely closed. In addition, since this soft adhesive strip has its side edges fixed in the groove, this edge pasting material is softer when the sliding door is closed than the conventional soft strips fixed to the surface or side surface of the substrate. Since the band-shaped body is pushed into the groove, the gap between the pillar and the sliding door is usually as small as 0.3 to 0.5 mm as shown in the cross section in FIG. 10, and the conventional product shows the cross section in FIG. As described above, the gap between the pillar and the sliding door is usually 2.0 mm, which is very small and the finish is beautiful.

Further, the thickness of the substrate is 0.8 to 15 mm, the depth of the groove is 0.3 to 7.0 mm, and the width of the groove is 1.5 to.
Within the range of 30 mm, the thickness of the soft strip is 1.5 mm
In addition, the height of the soft strip is 0.
If the protrusion is made to a height within the range of 3 to 10 mm, the gap between the pillar and the sliding door can be closed exactly.

In order to attach the edge sticking material to the front edge surface of the sliding door or the front edge surface of the door, a method of sticking with an automatic edge sticking machine is generally used. However, in this method, an edge is made with a pressing roller made of iron or hard resin. Since the patch is pressed from above onto the edge,
If the cross-section of the edge patch is not uniform, the pressure will not be applied evenly to the edge patch, causing adhesion failure. . However, the edge pasting material according to the present invention is provided with a groove on the hard substrate, and the cross-sectional area of the groove is equal to or larger than the cross-sectional area of the soft strip, and the side edge of the soft strip is further increased. Since it is fixed in the groove, when the surface of the edge pasting material is strongly pressed with a roll, the protruding soft strip is completely pushed into the groove, so the entire edge strip is entirely composed of the strip substrate. As they are, they act as uniform thickness. Therefore, the edge applying material according to the present invention can be applied over the entire fore edge by an automatic edge applying machine, which is convenient for use.

Furthermore, when the edge-adhesive material according to the present invention is piled up and rolled up and tightly tightened, the soft strip is pushed into the groove of the substrate as in the case of pressing with the above-mentioned roller. In addition, only the strip-shaped substrate is in a state of being wound in a roll shape, and therefore, it can be transported or stored with a low bulk. Also, since it can be attached to the automatic edge pasting machine in a rolled state, it is convenient for continuous pasting by the automatic edge pasting machine.

In addition, the edge pasting material according to the present invention can be subjected to gravure printing on the belt-shaped substrate after forming the edge pasting material structure. That is, the rimming material may be required to show an orderly wood grain pattern, and for this reason, it is necessary to print with a gravure roll after forming the structure of the rimming material. In the conventional edge pasting material in which the band-shaped body of the soft resin is projected on the surface, it is impossible to apply the gravure roll because the projecting portion interferes, but in the edge pasting material according to the present invention, as described above, The body can be pressed into the grooves of the substrate so that gravure printing can be applied. In this respect also, the edge patch according to the present invention is convenient in use.

Further, since the edge pasting material has the performance of the conventional packing material, the packing material is attached only by attaching the edge adhesive material, and therefore, it is not necessary to attach the packing material again. The present invention provides such advantages.
