Problems solved by technology

In addition, no adhesive force is applied because no engaging elements are present in these spaces, and to prevent lateral intrusion into the wall thickness
As a result, it becomes more difficult to obtain the desired adhesion

Embodiment Construction

[0041] Hereinafter, some embodiments of the present invention will be described in detail with reference to the accompanying drawings. Figure 1-8 A first embodiment of the present invention is shown.

[0042] like figure 1 As shown in , many engaging elements 3 in a hook shape are on one surface of the flat-shaped base member 2 of the strip-shaped molded surface fastener 1 of this embodiment except for two edge portions. Formed in the joining element forming area, three rows of longitudinal wall portions 4 are erected as the first resin intrusion preventing means of the present invention along one longitudinal direction on both side edge portions of the base member 2 so that they are line-like in parallel ground layout. like Figure 1-3 , As shown in 6 and 8, these longitudinal wall portions 4 are constituted by a plurality of partition walls 5 separated at a predetermined pitch (Pitch) along the longitudinal direction. The three rows of longitudinal wall sections 4 are ...

Abstract

The invention provides a molded surface fastener and a cushion body formed integrally with it wherein a molded surface fastener has first resin invasion preventing means of an expandable resin material for molding a cushion body on each of right and left side edge portions along a longitudinal direction of a thermoplastic-resin base member surface, a number of engaging elements provided between the invasion preventing means, and second resin invasion preventing means for sectioning the engaging elements into desired number of regions along the longitudinal direction of the base member and extending in a width direction between adjacent sectioned regions, the second resin invasion preventing means comprising a function for engaging / disengaging a mating engaging element, thereby the molded surface fastener securing a required binding force.

Description

technical field [0001] The present invention relates to a surface fastener and an anti-intrusion device. Fitting annular female engaging elements (female engaging elements) on one surface of its flat base member engaged by a piece, said intrusion prevention means at least along the left and right side edge portions in the longitudinal direction of the base member for Intrusion of a molding resin material into an engaging element forming region is prevented when the product is molded. Background technique [0002] Passenger seats in cars or trains, as well as various sofas and office chairs, have a cushion body inside their skin material. As this cushion body, so-called asbestos obtained by entanglement of palm fibers and flax or synthetic fibers of various rigid fibers and hardened together with rubber or the like, or various molded bodies are used, and the above-mentioned molded bodies The body is made of various hair resin materials. These cushion materials have a curve...
