Description

  The present invention relates to a “eyelet” that is attached to a hole in fabric. This eyelet is used for a hole in the head of the curtain for passing through a rod for curtain hanging, but is not limited thereto.

Curtains hung on curtain rods usually have "curtain heading tapes" sewn or secured to the heading part of the curtain fabric, which tapes are arranged in multiple rows. Holes are provided. This tape reinforces the "eyelet" fixed in this line of holes.
One known arrangement example is given. The first eyelet structure has an annular shape having a plurality of peripheral flanges spaced on both sides, and is fixed in advance to the hole of the head tape so that the tape material is sandwiched between the plurality of peripheral flanges. Yes. The second eyelet structure is in the form of an annular insert having a peripheral flange on one side. When the second eyelet structure is pushed into each hole of the curtain material, the second eyelet structure is engaged with and coupled with the first eyelet structure, and the curtain material has a peripheral flange of the second structure and a peripheral flange of the first structure. It is sandwiched between.
Since different curtain materials have different thicknesses, this known arrangement allows the second eyelet structure to be easily and reliably connected to the first structure for all thickness curtain materials. There is a problem that it cannot be combined.

  One object of the present invention is to provide an eyelet that can be easily and gracefully installed within a wide range of thickness fabric holes.

That is, the present invention is an eyelet for attaching to a hole in a cloth, and the eyelet is composed of first and second annular eyelet structures (1, 9), which are engaged with each other and connected. And each of these structures has flanges (5, 11) for holding the fabric between them, and these flanges are engaged with each other at different intervals. The eyelet is characterized by being (4a, 17a).
Because of this configuration, the eyelets can be easily attached to fabric materials of different thicknesses. In addition, the eyelet structure can be completely separated from the fabric material until use, so that it can be easily manufactured.
Regarding the ring eyelet structure, it is preferable that the structure is completely circular, but it may be only partially circular or a similar structure, and it is preferable that the peripheral part is also cyclic, but it is not necessarily continuous. Not necessary.

With respect to the flange, it is preferably a complete peripheral flange and preferably extends at least substantially radially to the annular end. However, it may be a partial peripheral flange or similar shape, or it may be discontinuously extending radially around the distal end.
Any suitable shape may be adopted for the meshing configuration. As an example, axially spaced grooves and / or protrusions or claws that can be coupled with one or more protrusions and / or grooves provided on a second ratchet or multi-step stepped part. A configuration comprising a first pawl having a ratchet or a multi-stage stepped component or other cooperating structure may be mentioned.

In addition to this configuration, it may have holding means (7a) to help maintain the position of these structures, for example to prevent relative rotation with respect to the fabric material. In such a configuration, one structure has one or more protruding needles or nails that cooperate with one or more receiving holes, indentations or grooves provided in the other structure; In use, the needle or nail is arranged to penetrate the fabric material.
Such needles or nails may be provided on one flange of the eyelet structure, and these receiving holes, indentations or grooves may be provided on the other flange.
In one embodiment, one flange may be provided with a plurality of circumferentially spaced needles or nails that cooperate with grooves circumferentially arranged on the other flange.

In a particularly preferred embodiment, each structure has a tube-like portion coupled to a radially extending flange at one end thereof, a free projection (eg, a nail) at the other end, and the tube-like portion is engaged. The one tubular portion is fitted into the other tubular portion in a shaft shape.
Each flange is in the shape of a “cap” having a radial wall and an inner curved edge around its outer periphery.

Each of the two eyelet structures may be an integrally molded part made of plastic, and these may be formed of any appropriate color and texture material.
The eyelet of the present invention may be used for curtain heading. For example, it may be used in a line of holes through a curtain head tape and a curtain material to which the tape is attached to receive a curtain rod. These are described in particular in our currently pending patent application.
However, the present invention is not limited to this example. This eyelet can be used for any suitable woven or other fabric material for a suitable purpose.

Hereinafter, the present invention will be illustrated with reference to the drawings.
1 and 2 are perspective views of first and second structures of one embodiment of the eyelet of the present invention. 3 to 6 are a cross-sectional view and a partially enlarged view of the combined eyelets.
FIG. 1 shows a grommet structure 1 in the form of an integrally molded plastic ring.
The ring has a coaxial open tubular part 2 in the center, which has an axial parallel plane 3 and is circular in cross section.
The outer surface 4 is usually axially parallel, but has a laminated body 4a of coaxial grooves with a curved cross section formed at equal intervals along the length direction of the annular part.

At one end of the tubular part 2 there is an integral circumferential flange 5, which is continuous and circular and has an outer periphery 6 that is coaxial with the tubular part 2.
The flange 5 has a wall 7 that is generally flat and radially spread, and has an edge 8 bent inwardly around the wall 7. For this purpose, the flange 5 has the shape of a cap that opens in the direction of the tube part 2.
A nail 7a is integrally attached to the wall 7 in a regularly arranged position inside this cap that is circularly coaxial with the tube part 2, and this nail 7a is edged in the direction of the tube part 2 8 protrudes.

FIG. 2 shows the second eyelet structure 9. As in FIG. 1, the eyelet structure 9 has a coaxial open tube-like portion 10, the tube-like portion 10 has a flange 11 at one end, and the flange 11 is formed by a flat plate and a radially extending wall 12. It has a bent edge 13 so that it has a cap shape.
Inside the cap 13 are two coaxial walls 14 and 15, which are the same height as the edge 13, so that a groove 16 is formed between them and is open in the direction of the tube portion 10. .
The tube portion 10 has a laminated body 17 a having a curved cross section, which is similar to the groove of the tube portion, but is provided on the inner surface 17 of the tube portion 10. The inner surface 18 of the tube portion 10 is an axial parallel plane.
The tube portion 10 of the second structure 9 is wider than the tube-shaped portion 2 of the first structure 1, that is, the inner diameter of the tube portion 10 is substantially equal to the outer diameter of the tube-shaped portion 2.

As shown in FIGS. 3 to 6, the tubular portion 2 of the first structure 1 enters the tubular portion 10 of the second structure, and the laminate 4 a and the laminate 17 a are engaged with each other. That is, the two structures 1 and 9 are pressure-fitted so that the protrusions of one stacked body engage with the grooves of the other stacked body.
The stacked body 4a and the stacked body 17a function like a ratchet. Therefore, the two structures 1 and 9 are separated from each other by two flanges at different intervals determined by the engaging protrusions and grooves of the stacked body 4a and the stacked body 17a. 5 and 11. Since the projections and grooves of the two laminates 4a, 17a have similar cross sections and the material of the tube-like parts 2, 10 is slightly elastic, the tube-like part 2 has different depths in the tube-like part 10. It is held at this fixed depth unless it is pushed and pulled strongly.

When the eyelet of the present invention is used for heading a fabric curtain having a fabric curtain heading tape with a line of holes in the tape and curtain heading, one structure 1 is By pushing the eyelet structure through the hole in the curtain head and pressing the other structure 9 through the hole in the tape, the two eyelet structures are joined together.
When fully indented, the curtain and tape material are held firmly between the two flanges 5, 11 by the free ends of the edges 8, 11 in contact with the fabric.

In this arrangement, the nail 7a penetrates the fabric material and enters the groove 16, thereby holding the eyelet in this position and preventing the eyelet from rotating relative to the material.
In this embodiment, the eyelet can be easily attached to a line of holes in a wide range of curtains and tapes by utilizing this eyelet and tape configuration that can be easily manufactured. Can do.
