This invention provides a female-male engaging device with tapes having a flat shape and a good appearance, wherein a female engaging device and a male engaging device can be easily engaged and disengaged with each other. The female engaging device and the male engaging device are mounted to a side edge of a tape at intervals, the female engaging device is defined with a leg portion for sandwiching the edge portion of the tape, a cavity portion in front face of the leg portion, and a laterally long engaging hole in a front wall, and the male engaging device is defined with a leg portion for sandwiching the edge portion of the tape, a neck portion at a front face of the leg portion having a size substantially corresponding to that of the engaging hole, and a bulging engaging head at a front face of the neck portion having a constant width and a front face in a shape of a Rugby ball, a thickness of a center portion of the engaging head is larger than that of the engaging hole, and a thickness of each of opposite ends of the engaging head is smaller than that of the engaging hole. The engaging head is inserted from its opposite ends and engaged with the engaging hole, and the engaging head is disengaged from the engaging hole by pulling an end portion side. Because the engaging and disengaging operations are only in a plane direction, the operations are easy.
A female-male engaging device with tapes, comprising, a female engaging device having a leg portion mounted to a side edge of a tape at intervals faces a male engaging device mounted to a side edge of a tape at intervals, the female engaging device is defined with a leg portion for sandwiching the tape, a cavity portion vertically penetrating and extending through the female engaging device in front of the leg portion, and an engaging hole in a front wall at a front end of the cavity portion communicating with the cavity portion, and the male engaging device is defined with a leg portion for sandwiching the tape, and a bulging engaging head projecting from a front face of the leg portion to be fitted into the engaging hole and into the cavity and engaged behind the front wall of the cavity portion such that the female engaging device and the male engaging device can be pushed against each other in a plane direction for engaging and disengaging with each other.
A female-male engaging device with tapes comprising a female engaging device mounted to a side edge of a tape at intervals faces a male engaging device mounted to a side edge of a tape at intervals, the female engaging device is defined with a leg portion for sandwiching the tape, two spaced tongue portions disposed at upper and lower portions of a front face of the leg portion, a cavity portion extending vertically through center portions of the tongue portions, and engaging portions forming the periphery of the cavity at front ends of the tongue portions, and the male engaging device having a leg portion for sandwiching the tape, and a bulging engaging head projecting from a front face of the leg portion for engagement with the engaging portions, such that the female engaging device and the male engaging device can be pushed against each other in a plane direction for engaging and disengaging with each other.
