Definitions

  • the present invention relates to a slider for a concealed type slide fastener in which a main body of the slider which is an opening/closing device is not exposed outside when the slide fastener is closed, and more particularly, to a slider for a concealed type slide fastener which enables a smooth sliding operation even if a strong horizontal pulling force is applied when the slide fastener is closed.
  • the cushion body allows the cushion body to be deformed elastically so as to correspond easily to a distribution of load of a human body when a passenger is seated; and to be restored to its original shape securely when he/she leaves the seat, thereby keeping the shape of the cushion body from being lost.
  • the seat cover comprises a seat including a surface layer, a thin elastic intermediate layer and a back base fabric layer, which are integrally laminated.
  • the surface layer is composed of natural leather, synthetic leather or woven/knitted fabric having a variety of structures.
  • the intermediate layer is composed of a polyurethane foamed seat or the like.
  • the back base fabric layer is composed of a thin woven/knitted fabric or the like obtained by weaving or knitting with extremely thin yarns.
  • the seat is cut so as to form a plurality of seat pieces according to the shape of a passenger seat, and these seat pieces are sewed together three-dimensionally to produce a seat cover.
  • a non-sewed portion is prepared preliminarily, and after the cushion body is covered with the seat cover, the non-sewed portion is sewed by hand.
  • a slide fastener particularly, a concealed type slide fastener which keeps its slider main body from being exposed outside has been often used in part of a sewing portion of the seat cover, for example, along an astragal portion in order to eliminate the sewing operation by hand.
  • the entire sewing operation can be carried out with a sewing machine, so that conventional faults based on the difference of skill are reduced largely, thereby improving productivity enormously.
  • a pair of right and left first flanges each having an inverted L shaped section are erected on the respective side edges orthogonal to a slider sliding direction of a lower blade of a slider body.
  • the pair of first flanges have linear portions parallel to each other and expanded portions which are expanded while bent so as to be depart from each other and continuous with the linear portions, in a flat surface view.
  • a diamond having a substantially elliptic horizontal section is erected vertically upward at an end portion on a expanded portion side of the lower blade.
  • a second flange is formed integrally on a top surface of the diamond, and a gate type pull-tab attaching post which extends in a sliding direction is formed integrally on a top surface of the second flange.

  • the conventional concealed type slide fastener obtained by inserting the slider having the above-described structure is applied to the seat cover of the passenger seat of the automobile or the like, and finally the concealed type slide fastener is closed, a strong horizontal pulling force is applied to the fastener stringers in the vicinity of the slider because the seat cover is formed in a smaller size than the external dimension of the cushion body.
  • This strong horizontal pulling force raises the engaging element rows vertically due to the structure peculiar to the above-described concealed type slider fastener.
  • a second flange having the same thickness as that of the first flange extends along the right and left sides of the diamond from an end face on the shoulder mouth in the conventional slider.
  • Respective elements introduced to the shoulder mouth while receiving a horizontal pulling force at a portion near the shoulder mouth of the second flange are raised up to substantially right angle with respect to a tape surface of the fastener tape.
  • these elements are introduced into the element guide passage of the slider and affected by a tilting force by preceding elements in the inclined state due to a contact with the first flange, the diamond and the top plate portion of the second flange and by a relative pulling force of a fastener tape T based on the sliding operation of the slider. For this reason, when the coupling portion of each element is mounted on the top surface of the lower blade of the slider, it is tilted slightly.
  • each element is nipped between the first flange and the second flange because the tilting is small, thereby disabling the slider from sliding. If a user tries to slide the slider compulsorily, not only the element is damaged but also the bent edge of the fastener tape may be broken.
  • an object of the invention is to provide a slider for a concealed type slide fastener which can achieve a smooth sliding operation of the slider even if a strong horizontal pulling force is applied when the slide fastener is closed in a case where the slide fastener is applied to, for example, a seat cover of a passenger seat or the like.

  • a Y-shaped tape guide passage is formed between each of the top plate portions of the first flanges and the second flange, and a bottom surface of an edge portion on an inside portion of each of the first flanges, which is sectioned into inside and outside portions by an extension line of a long side of the rectangular plate portion of the second flange, is formed more thinly than a bottom surface of the outside portion via a step portion.
  • a tapered surface which is expanded upward from its bottom end is formed at least in an outside area of a shoulder mouth side of a portion intersecting with the straight line L passing the diamond side end face of each of the top plate portions of the first flanges each having an inverted L-shape section erected from right and left sides of the lower blade, the portion in the second flange having the rectangular plate portion formed integrally on the top surface of the diamond on the diamond side (shoulder mouth side) and the wedge plate portion extending in the sliding direction from the rectangular plate portion in the slider for the concealed type slide fastener.
  • the top end ridge line of the tapered surface is set lower than the top surface of the top plate portion of the first flange and higher than a height between the top surface of the lower blade and the bottom surface of the top plate portion. For this reason, when the fastener is closed, a strong horizontal pulling force is applied to the fastener tape in the concealed type slide fastener attached on a seat cover which covers the passenger seat of an automobile or the like.
  • the engaging elements introduced successively into the element guide passage formed with the shoulder mouth, the lower blade, the diamond, the first flange and the second flange are changed in their attitude from a substantially parallel attitude to the tape surface of the fastener tape at a position apart from the shoulder mouth to an attitude in which the coupling portion of the element is located above while the engaging head is located below as the element approaches the shoulder mouth, so that the element mounting portion is inverted and raised at the right angle to the tape surface.
  • the dimension between the bottom surface of the second flange and the lower blade is not different near the shoulder mouth end portion or at the rear mouth side end portion of the second flange.
  • the element placed on the lower blade on the shoulder mouth side is tilted slightly by receiving an influence of a pulling force and a force trying to tilt the element from an element and tape already introduced into the element passage.

  • the element introduced smoothly into the element guide passage of the slider as described above is introduced to the bottom surface of the wedge plate portion of the second flange step-by-step while the engaging head is guided by the tapered surface of the second flange and taken to the rear mouth, so that the element turns to a engagement state substantially horizontal.
  • the element Just after the element surpasses the front end of the wedge plate portion of the second flange, it is engaged with a mating element completely and guided to the rear mouth.
