Male fixing member of hook-and loop fastener, and sheet product with the fixing member

Abstract

A first base material having a number of male engaging elements (112) formed of synthetic resin on a surface thereof and a second base material (121) are jointed and secured each other through a column-like joint portion (131). There is provided a male fixing member for sheets, which facilitates attachment operation to clothes or suspension cloths, has a durability, never loses appearance when it is mounted on clothes and allows even an infant to engage or disengage the male fixing members easily by an engagement / disengagement function of a surface fastener.

Description

TECHNICAL FIELD [0001] The present invention relates to a male fixing member which is attached to clothes such as outdoor wears and various kinds of shirt and suspension cloth such as a curtain and a table skirt and has a number of male engaging elements allowing engagement and disengagement thereof to a mating member through an engaging / disengaging mechanism of a surface fastener, and relates to a sheet product such as clothes and suspension screen to which the male fixing members are attached. BACKGROUND ART [0002] Conventionally, various kinds of fixing devices have been used at an opening / closing portion of clothes and an engaging / disengaging portion for a curtain and a runner. Its typical fixing device is buttons. As extremely ordinary buttons, there are buttons used for outdoor wears, shirts and blouses. According to this device, a button main body fixed to one side of the opening / closing portion of clothes with threads is inserted into a slit-like button hole formed in the ot...

Benefits of technology

[0017] Further, according to the present invention, under the above-described structure, the first base material and the male engaging elements are formed of synthetic resin material while the first base material and the male engaging elements are molded integrally. According to the present invention, regardless of whether the first base material is molded integrally with the column-like joint portion or the first base material is formed independently, in case of the first base material composed of synthetic resin material, a number of male engaging elements are molded integrally with the first base material at the time of molding. With such a structure, not only productivity can be raised but also as compared to a case where the male engaging elements and the first base material are formed independently and integrated later, a phenomenon that the male engaging elements may be separated from the first base material is eliminated despite repeated usage and durability can be ensured.

[0019] In this case, the joint portion is pierced into a sheet product, a front end portion of the joint portion is inserted through the insertion hole from a rear face toward the front surface of the first base material and the projecting end portion is deformed plastically so that it is expanded in a direction perpendicular to an axial direction of the joint portion. Consequently, it is attached to the sheet product under conditions in which a fixing portion and a fastening portion are integrated. Because the male fixing member of the surface fastener of the present invention attached in this way is mounted securely on the sheet product and further, the column-like joint portion has a high tensile strength and shearing strength, it is never damaged easily by repeated usage and washing. Meanwhile, not only the first base material but also the fastening portion can be formed of any one of metallic material and synthetic resin material.

[0020] Further, preferably, the front end portion of the column-like joint portion has an engaging / disengaging head portion and the joint portion of the first base material or the second base material which is to be fixed with the column-like joint portion has an engaging / disengaging portion which allows engagement / disengagement of the column-like joint portion with / from the engaging / disengaging head portion. The engaging / disengaging portion which the engaging / disengaging head portion engages or disengages is preferred to be constructed in the same structure as the snap structure in the snap button. With such a structure, after the column-like joint portion is pierced into the sheet product, the first base material and the second base material can be integrated easily with a simple action by pressing with the fingers and if necessary, they can be removed easily if they are pulled in the direction of departing.

[0022] Further, preferably, the first base material or the second base material has an insertion hole for the column-like joint portion in the center, and has an expanded portion provided around the insertion hole and plural sliding preventing protrusions provided around the expanded portion at a predetermined interval. The expanded portion around the insertion hole not only secures the strength of the surrounding of the insertion hole, but also increases a nipping strength for the sheet member, so that the male fixing member of the present invention can be fastened to the sheet member firmly. Further, at the time of fastening, the plural protrusions around the expanded portion bite into the sheet member thereby preventing the male fixing member from sliding on the sheet member.

Problems solved by technology

These operations are very difficult for infants, persons handicapped in finger action and aged persons although not for healthy adults and therefore, the buttons are fixing devices very difficult to handle.

However, the snap button cannot be in an excellent engagement unless the male device and female device are aligned with each other in the center and pressed together.

That is, like the aforementioned ordinary buttons, this snap button is a very difficult fixing device for persons handicapped in the finger action or eyesight, infants and aged persons.

However, the attachment operation is complicated and its practical usage is difficult in terms of durability and appearance.

Thus, the sewing thread which joints the substrate with the button is easy to cut out due to repeated usage or washing and thus, the durability is low.

Thus, an end of the sewing thread is exposed on the surface of clothes so that not only the appearance is damaged but also that end of the thread is likely to be caught by other things and cut out.

Consequently, when the opening / closing portion is closed, only that fixing device mounting portion swells, so that the appearance beauty deteriorates, which is not suitable for practical usage.
