Abstract:
1. A fastening structure for fastening a plurality of objects to each other, the objects respectively having planar portions and facing each other, the fastening structure comprising: a first zipper rail unit provided on a planar portion of a first object, the first zipper rail unit comprising a plurality of zipper rails made of elastic material and arranged parallel to each other; and a second zipper rail unit provided on a planar portion of a second object, the second zipper rail unit comprising a plurality of zipper rails made of elastic material and arranged parallel to each other, wherein while the zipper rails of the first zipper rail unit are individually coupled to the corresponding zipper rails of the second zipper rail unit in a female-male engagement manner, relative positions between the first object and the second object are able to be changed with respect to a longitudinal direction of the zipper rails, wherein the first object is coupled to the second object by force-fitting or is removed therefrom by pulling wherein each of the zipper rail units comprises a plurality of female zipper rails and male zipper rails made of elastic material and alternately arranged on at least one surface of a zipper rail plate, wherein a cross-sectional area of each of the female zipper rails is larger than a cross-sectional area of each of the male zipper rails, and the zipper rails of the pair of zipper rail units that correspond to each other are individually coupled to each other in the female-male engagement manner; wherein each of the male zipper rails comprises: an extension part perpendicularly extending from the zipper rail plate; and a ball-shaped head part provided on an end of the extension part, the head part having an increased width, and each of the female zipper rails comprises a receiving space defined both by surfaces of the extension parts and head parts of the adjacent male zipper rails and by a surface of the zipper rail plate in such a way that each of the ball-shaped head part engages with each of the female zipper rails by directly touching the surface of the zipper rail plate; wherein while the zipper rails of the pair of zipper rail units that correspond to each other are individually coupled to each other in the female-male engagement manner, each of the female zipper rails of one of the pair of zipper rail units and the corresponding male zipper rail of a remaining one of the pair of zipper rail units are coupled to each other in such a way as to form at least two-point contact structure when seen in a sectional view; and wherein the zipper rail plate has a planar shape so that the zipper rail plate can be attached to either one of the objects, and at least one perforated line is formed in the zipper rail plate so that each zipper rail unit can be divided into a plurality of smaller zipper rail units.
