Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a large eyelet installed in a row on the upper end side of a curtain fabric.
[0002]
[Prior art]
Conventionally, as shown in FIGS. 6 and 7, a male ring member 91 having a cylindrical engagement leg 93 formed at the center and a flange portion 94 formed all around from the base end of the engagement leg, An eyelet (hereinafter referred to as “prior art 1”) that includes a female ring member 90 having a fitting hole 95 that fits with the joint leg 93 and that is fitted and fixed with the attachment fabric 92 sandwiched between the peripheral edge portions 96 and 97. Widely used.
[0003]
However, since the eyelet has a structure in which the attachment fabric 92 is sandwiched between the outer peripheral edge portions 96 and 97 of the male ring member 91 and the female ring member 90, particularly when the attachment fabric is thin. In this case, the gripping force on the attachment fabric 92 is not likely to act sufficiently. In such a case, the attachment strength is weakened, so that the eyelet easily falls off from the attachment fabric 92 or the male and female rings The members 90 and 91 rotate in the circumferential direction, causing problems such as deterioration in quality.
[0004]
In order to solve such problems, various eyelets in which protrusions are formed on the fabric contact surface of the female ring member have been disclosed. For example, the idea disclosed in Japanese Utility Model Publication No. 2-54408, that is, the eye A taper that includes a hole-shaped seat body and a grommet body that is fitted and fixed to the seat body, and that extends rearward and shrinks in the direction in which the grommet body should be fitted into the center hole of the seat body. A small-diameter arc-shaped small protrusion that protrudes in a direction to face the eyelet main body from a base end of the edge, and extends in the opposite direction and has a tip of the edge An arcuate bulging portion having a more protruding top, and piercing pieces are provided on the top surface of the arcuate projection so as to be distributed over the entire circumference, while the eyelet main body includes the seat body. A hollow cylindrical projecting edge having a sharp tip to be brought into sliding contact with the tip of the end edge. Eyelet formed by projecting from the base portion (hereinafter, referred to as prior art 2.) And,
In the invention according to Japanese Patent Laid-Open No. 2002-5140, that is, an eyelet washer that fits to the eyelet main body and is attached to the attachment fabric, an annular outer shape formed so that the inner peripheral portion protrudes from the surface of the outer peripheral portion. An eyelet (hereinafter, referred to as “prior art 3”) including an eyelet washer having a plurality of protrusions (corrugated protrusions) along the radial direction on the inner peripheral surface is known.
[0005]
[Problems to be solved by the invention]
Among the above, the device according to Prior Art 2 is a device in which a stab is formed on a small-diameter arc-shaped projection protruding in a direction to face the eyelet body, and the stab pierces the attachment fabric, The attachment fabric is secured without being displaced, and the attachment fabric is sandwiched between the arcuate protrusion and the eyelet main body, thereby securing the attachment strength.
[0006]
However, since the arcuate protrusion and the attachment contact portion of the attachment fabric in the eyelet main body are in line contact, and the stab is formed on the arcuate projection, the attachment fabric is actually sufficient. The part to be sandwiched is very limited, and although the stab is in a state of being stabbed against the attachment fabric, the stab is so small as to be caught by the fabric, so the sandwiched part When loosening or an excessive load is applied, the fabric may float from the stab in the eyelet or the fabric may come off, and it cannot be said that the mounting strength is excellent. In addition, as in the case of the prior art 1, this tendency becomes more prominent as the fabric is thin and the holding force on the attachment fabric 92 itself is less likely to act sufficiently.
[0007]
Further, the special configuration of forming the stab on the arcuate small protrusion has a drawback that the thickness of the eyelet increases when attached to the fabric. If the arc-shaped protrusion is flat to eliminate the disadvantage, the force for pressing the stab and the attachment fabric is diminished, and the stab is more likely to be detached from the attachment fabric. The said fault could not be eliminated.
[0008]
Next, as described above, the invention according to the prior art 3 forms a plurality of protrusions (corrugated protrusions) along the radial direction on the inner peripheral surface. The clamping is performed by line contact. Moreover, since a large space is formed between the protrusions, the attachment fabric cannot be sufficiently sandwiched between the protrusions. The attachment fabric had to be pinched only by the part, and the eyelet was not sufficiently fixed.
[0009]
In addition, in the case where the fixing by the protrusion is made more reliable, the protrusion can be increased in volume to secure the holding force. In such a case, the thickness of the entire eyelet is similar to the prior art 2. There is a drawback that becomes larger.
[0010]
This invention is made | formed in view of the above situation, and makes it a subject to provide the thin eyelet which the attachment strength with respect to attachment fabric is strong, and a male and female ring member does not rotate to the circumferential direction.
[0011]

In the eyelet that clamps and fixes the attachment fabric by the mutual outer peripheral edge of the ring member and the female ring member,
The female ring member (1) forms a plurality of fabric penetrating pieces (11) standing upright on the side peripheral edge (14) of the female-side clamping smooth surface (12). ) Is a shape inclined slightly inward from the vicinity of the center to the tip, and the fabric penetration piece (11) penetrates the attachment fabric (3) and is a smooth surface (22) for holding the male side of the male ring member (2).

FIG. FIG. 4 is a partially enlarged cross-sectional view showing an engaged state of the female ring member and the male ring member.
[0017]
As shown in FIGS. 1 to 5, the eyelet according to the embodiment of the present invention is continuously curved from the base end 23 of the flat plate-shaped flange portion 20 having an outer diameter of about 55 mm and has a width of about 40 mm in the ring central axis direction. A male ring member 2 made of brass having a configuration in which a cylindrical engagement leg 21 is formed;
An annular female-side clamping smooth surface 12 is provided which has an engagement hole 10 with a width of about 41.5 mm to which the engagement leg 21 is fitted and which faces the inner surface of the flat annular flange portion 20 in the male ring member 2. Formed and continuously penetrated into the side peripheral edge 14 of the female-side clamping smooth surface 12 by a pressing process to form a sharp isosceles triangular shape having a thickness of about 0.4 mm, a maximum width of 2.5 mm, and a height of about 3 mm. Twelve pieces 11 are formed upright at regular intervals along the female-side holding smooth surface 12 and are composed of a female ring member 2 made of brass having an outer diameter of about 55 mm.
[0018]
Here, the male ring member 2 is characterized in that a male-side holding smooth surface 22 is formed on the inner surface of the flange portion 20, and the male-side outer peripheral portion serving as the outer peripheral edge of the flange portion 20. In the same manner as a general eyelet, 25 is a folded shape by a press from the viewpoint of safety for fingers and the like during use.
[0019]
On the other hand, the female ring member 1 is obtained by pressing a brass plate having a thickness of 0.4 mm as a whole, and on the outer side of the ring-shaped female side holding smooth surface 12, The reinforcing peripheral portion 13 formed with a groove 17 having a substantially semicircular cross section for reinforcing the ring member 1 is continuously provided, and the entire circumference of the female holding smooth surface 12 is equally spaced. By punching, the dough penetrating pieces 11 and the holes 15 generated by forming the dough penetrating pieces 11 are provided at twelve places, and only the outer peripheral edge portion 16 of the female side that is the outer peripheral edge of the reinforcing peripheral edge portion 13 is provided. Has a light and thin form with a thickness of 0.25 mm.
[0020]
The dough penetrating piece 11 stands vertically from the base to the vicinity of the central portion with respect to the female-side holding smooth surface 12 and is slightly inclined inward from the vicinity of the central portion to the tip portion. Thus, as described above, as a whole, it is sharp with an approximately isosceles triangle shape having an apex angle as a tip portion.
[0021]
With the above-described configuration, when the attachment fabric is sandwiched between the male and female ring members 1 and 2 and the eyelet is attached, the fabric penetration piece 11 penetrates the attachment fabric 3 and abuts against the smooth surface 22 for holding the male side.
