Problems solved by technology

However, since the neck portion between the convex portion of the engaging element and the engaging head is narrow, when the engaging element is disengaged, the engaging heads are mutually pulled in opposite directions, thereby making the neck easily broken.
Due to repeated disengagement operations, the joint force is reduced, and the original function of the surface fastener will be lost in a short period of time.

[0064]The molded surface fastener 11 of this embodiment is characterized in that it has a fitting protrusion 6 . Like the first embodiment, the fitting protrusion 6 of this embodiment is also provided at the middle position of two engaging elements 3 adjacent in the width direction. The mating protrusion 6 includes a pair of elastic protrusions 6a, 6a protruding at a specific interval in the molding direction, and the outer surfaces of the two elastic protrusions 6a, 6a in the molding direction are inclined to the engaging element 3. The surface 3c basically has the inclined surface 6b at the same inclination angle.

[0065] In addition, the distance between the outer surfaces (inclined surfaces 6b, 6b) of the elastic protrusions 6a, 6a and the distance between the engaging heads 3b, 3b of the engaging elements 3, 3 located adjacent to the bottom ends thereof in the molding direction The gaps are substantially equal. In addition, the distance between the outer surfaces of th...

Abstract

A molded surface fastener has no stagger between the once engaged engaging elements and has high engagement force so as to strongly prevent the release of the engaging elements, whereby, it is possible to smoothly press and joint the molded surface fasteners made of a synthetic resin each other. A molded surface fastener made of a synthetic resin has an engaging element and a fitting projection on a surface of a plate-like substrate. The engaging element has a rising portion, which rises from a surface of the plate-like substrate and has an opposite pair of inclined faces, and an engaging head which is continuously formed on a top end of the rising portion and which is expanded at sides of opposite vertical faces in a horizontal direction except for the inclined faces. The fitting projection is positioned between the facing inclined faces of an adjacent pair of engaging elements of a mating surface fastener upon engagement of the engaging elements each other and has inclined faces, which are fit with and abut against both inclined faces, so that it is possible to prevent the stagger upon engagement.

Description

technical field [0001] The present invention relates to a molded surface fastener integrally molded from thermoplastic synthetic resin. More particularly, the present invention relates to a molded surface fastener in which engaging elements having substantially the same shape are securely engaged with each other by pressure. Background technique [0002] Generally, people use molded surface fasteners which are integrally molded on a plate-like base from a synthetic resin material and which allow engaging elements having approximately the same shape to be joined together by pressure, because molded surface fasteners are easy to engage , and the joint strength of molded surface fasteners is high, therefore, molded surface fasteners are especially suitable for connecting industrial materials and interior decoration parts together. [0003] For example, the molded surface fastener disclosed in JP2994464A includes a mushroom-shaped engaging element having a raised portion raised...
