Definitions
- the present invention has a male engaging element composed of a number of hook pieces and mushroom pieces engaged with a mating loop-shaped female engaging element on one side of a flat base material, and at least left and right in the longitudinal direction of the base material.
- Molded male surface fastener having a resin intrusion prevention wall portion arranged along the side edge to prevent the foamed resin material from entering the formation area of the male engagement element during foam molding of a molded product made of foam resin.
- a cushion material called rock wool or the like which is obtained by confounding rigid fibers such as coconut, hemp or thick synthetic fibers and hardened with rubber or the like, or a foam molded body made of various foamable resin materials is used.
- These cushion materials have a curved surface having an uneven shape satisfying ergonomics in order to maintain a seating posture that does not get tired even when seated for a long time.
- mass production of such a cushioning material having a complicated surface shape is made efficiently in consideration of its cushioning properties, it is difficult to cope with the rock wool having many manufacturing processes.
- cushion bodies made of foamable resin are widely used because they can be manufactured in a single process and various shapes can be easily obtained. That is, the foam body made of foamable resin is formed into a desired shape simultaneously with foaming by pouring a foamable resin material such as foamed urethane resin into the mold.
- the surface of the cushion body formed in this way is integrated with various fiber fabrics and skin materials such as natural or synthetic leather.
- a skin material is adsorbed along the mold surface, a foamed resin material is poured into the mold, and a cushion body is molded and simultaneously integrated with the back surface of the skin material, or in advance
- any of means for covering and fixing a skin material on the surface is employed.
- the skin material when setting the skin material along the inner surface of the mold, the skin material is adsorbed along the inner surface of the mold using suction means.
- the skin material In order to deform according to the cushion body surface having a shape, the skin material itself needs to be a material excellent in stretchability. However, since stretchability is limited depending on the material, a great number of wrinkles are likely to occur particularly between the seating surface and the peripheral side surface, and great efforts are made to correct this.
- the cushion body and the skin material are integrated on the entire surface, for example, when a strong force is applied in the direction in which the skin material is displaced on the surface of the cushion body during use, the skin material and the cushion body In some cases, a shearing force acts between them to tear a part of the cushion body and peel the skin material.
- the materials that can be used as the skin material are limited, and it is preferable that a slight movement can be allowed between the skin material and the cushion body so that no excessive force is applied. . Therefore, instead of integrating the skin material at the same time as the formation of the cushion body, a method of covering the skin material on the cushion body that has been molded in advance has been often adopted.
- the general method for integrating the molded male surface fastener when molding the cushion body made of the foamable resin material as described above is to mold the engaging element forming surface of the male surface fastener 1.
- the cushioning body is foam-molded by pouring the foaming resin material into the mold 100 and mounting and fixing to the projecting surface part 101 toward the projecting surface part 101 of the mold bottom surface corresponding to the concave surface of the cushion body.
- the engaging element forming surface of the male surface fastener 1 is embedded and integrated in the recessed surface of the cushion body so as to be exposed to the outside.
- foam molding it is necessary to prevent the foamable resin material from flowing into the formation area of the male engagement element.
- the formed cushion body is covered with a skin material made of various materials such as pile knitted fabric, natural leather, rigid leather, etc., which is formed in a bag shape according to the outer shape of the cushion body in advance.
- the female engaging element is pressed against the engaging element forming surface of the male surface fastener 1 integrated with the cushion body, and the skin material is joined and fixed along the recessed surface of the cushion body. So that it does n’t float up.
- Patent Document 1 Japanese Unexamined Patent Publication No. 2000-516485
- US Patent for example, measures to prevent the foamable resin material from entering the engaging element forming region of the male surface fastener when molding the cushion body.
- Patent Document 2 Japanese Patent Application Laid-Open No. 2005-211198
- Patent Document 3 Japanese Patent Application Laid-Open No. 2005-211198
- Patent Document 1 a large number of male engaging elements are erected on one surface of a base tape by integral molding, and the male engaging elements disposed in the peripheral portion of the male engaging element forming region are embedded. Covering with a synthetic resin cover, an intrusion prevention wall of the foamed resin material is formed so as to surround the periphery of the male engagement element formation region.
- the inside of the synthetic resin cover may or may not be filled with the same type of resin as the cover.
- particles made of a magnetically attracted material or a magnetically attracted magnet may be mixed in the constituent resin material of the synthetic resin cover.
- magnetically attractable particles are included along the outer edge of the engaging element forming region of the molded male surface fastener in which a large number of male engaging elements are formed and integrated on the surface.
- the anchor wire having a large number of fibers attached to the peripheral surface is directly bonded and fixed to the surface of the flat substrate through an adhesive to form a resin intrusion prevention wall portion.
- the male surface fastener disclosed in Patent Literature 3 prevents the foamed resin material for molding of the cushion body from entering the left and right side edges along the longitudinal direction of the long tape-shaped base material made of thermoplastic resin.
- the first resin intrusion prevention wall portion extends, and has a plurality of male engagement elements between the left and right intrusion prevention wall portions, and the male engagement elements are arranged for each required region in the length direction of the substrate.
- a second resin intrusion prevention wall portion that is partitioned and extends in the width direction of the base material is formed between partition regions adjacent in the longitudinal direction.
- the second resin intrusion prevention wall extends in the width direction of the base material surface and prevents the intrusion of the foamed resin material for forming the cushion body from the longitudinal direction of the base material.
- a hook-shaped male engagement element that engages and disengages with the counterpart female engagement element is provided at the upper end of the resin intrusion prevention wall portion 2.
- the second resin intrusion prevention wall portion constitutes a resin intrusion prevention lateral wall continuously extending in the width direction of the base material surface, and is disposed at the upper part of the resin intrusion prevention lateral wall and in the longitudinal direction of the base material.
- the resin intrusion prevention lateral wall prevents the foamable resin from entering the engagement element formation region and is formed in the engagement element formation region.
- the male engagement element with the same engagement head as the engagement element is joined to the female engagement element on the back of the skin material, thereby complementing the previously lacked part to be joined and ensuring the required joining force. To do.
- the molded male surface fastener molded and integrated with the cushion body is joined and integrated with the cushion body in the outer region of the back surface of the base material and the first and second intrusion prevention wall portions.
- the back surface thereof is made uneven, or a nonwoven fabric or the like is integrated on the back surface.
- the molded male surface of the molded male surface fastener is brought into close contact with a predetermined position of the molding die.
- a long magnetic wire is embedded and integrated along the longitudinal direction of the base material in each of the base-side base portions of the left and right first resin prevention wall portions of the surface fastener and the width direction center portion of the base material.
- the magnetic wire is made of a magnetically attracted wire or a linear magnet.
- the magnetically attracted wire for example, a simple metal single filament or a synthetic resin monofilament mixed with magnetically attractable particles is often used. Therefore, all of these wires are excellent in flexibility.
- the male surface fastener disclosed in Patent Document 1 is not manufactured continuously, as can be understood from the above-described structure.
- the male surface fastener member and the engaging element of the surface fastener member are not manufactured continuously. It is individually manufactured as a single member through two or more steps of forming a cover that covers the peripheral engagement elements in the formation region.
- the male surface fastener member is a molded surface fastener, the surface fastener members are molded individually rather than continuously. Therefore, although the male surface fastener disclosed in Patent Document 1 cannot be manufactured in a single process, it has a problem that the manufacturing cost increases.
- an uneven surface composed of a moderately curved surface is formed on the seat surface in order to obtain the most preferable ergonomic seating posture as described above.
- the shape of the uneven surface particularly its length, is not constant and has various lengths.
- the molded surface fastener is integrated with the cushion body along the concave portion of the seating surface of the seat cushion body having an uneven surface.
- the skin material is tightly cushioned by pressing and joining the female surface fastener region having the female engagement element on the back surface of the skin material to the engagement element forming region of the surface fastener. Attached to the body.
- each of the first resin intrusion prevention walls formed along the left and right side edges is intermittently arranged in two or more rows in a staggered manner instead of continuously.
- the male surface fastener can be easily and accurately placed at an arbitrary position on the mold when there is little unevenness on the surface fastener adsorption surface of the mold and is close to a flat surface.

図1に示すように、本実施例に係わるテープ状の成形雄面ファスナー1(以下、単に面ファスナーという。)は、平板状基材2の片面の幅方向の両側縁部分を除いた係合素子形成領域30に多数のフック状の雄係合素子3が基材2の片面(表面)に一体に成形され、同基材2の左右両側端縁部分には長手方向に沿って直線状に延びる樹脂侵入防止壁部4が立設されている。本実施例にあって、前記樹脂侵入防止壁部4は、前記係合素子形成領域に隣接する左右側縁部に、それぞれ所要の間隔をおいて長手方向に平行に配された第1及び第2線状シール体挟持部4a,4bと、第2線状シール体挟持部4bの係合素子形成領域とは反対側に密接して配された外壁部6と、前記第1及び第2線状シール体挟持部4a,4bに配され基材2の表面から隆起する線状シール体5を下方から支持する線状シール体支持部7とを有している。
図14Aに示す変形例では、上記実施例のように第1及び第2線状シール体挟持部4a,4bの上端に係止部を形成せず、金属や磁石などの磁性材料からなる金属線材5”を芯材として、その周面を複数本の繊維製紐材5’を被覆した線状シール体5を線状シール体支持部7及び第1及び第2線状シール体挟持部4a,4bの対向面に接着剤などを塗布して接着固定している。なお、接着剤は必ずしも必要ではなく、例えば後述するダイホイールによる面ファスナー成形時に同時に線状シール体を導入することによっても作成することができる。図14Bの変形例によれば、第1及び第2線状シール体挟持部4a,4bの間と線状シール体支持部7とによって形成される直線状の空間部に、加熱して溶融した磁性材料を含有する合成樹脂を流し込んで第1及び第2線状シール体挟持部4a,4bと線状シール体支持部7との間の空間部に線状シール体5を形成している。
まず、図16に示す製造装置によると、一方向に駆動回転するダイホイール300の周面に溶融樹脂材料の連続押出しノズル301を対設している。このダイホイール300の周面中央部領域には多数の雄係合素子成形用キャビティ302が形成されており、同周面の軸方向両端縁部には周方向に延びて上記第1及び第2線状シール体挟持部4a,4bを成形するための複数列の図示せぬ挟持部成形用キャビティが間欠的に又は連続して形成されている。一方、前記押出しノズル301との対面位置に設置された前記ダイホイール300の周面部位の回転方向上流側にピックアップロール303が設置されており、更に、このピックアップロール303より下流側に上下一対の押圧ロール304,305が設置されている。上部の押圧ロール304は内部に図示せぬ加熱部を有し、この上部押圧ロール304を所要温度に加熱している。
