Abstract: A combined structure of a sports shoe and an in-line skate mainly comprises an in-line wheel device buried in the shoe bottom of a sports shoe. The in-line wheel device comprises a base, whereon a linkage set, a position plate, a wheel position mechanism and a torsion spring are combined in order at both sides by position pins and shaft bars and arrangement at each side is homologous with the other side such that wheels are set among two sides and arranged in in-line state. Besides, a control mechanism is combined to the rear of the base and can control wheels to be unfolded and taken in automatically such that the shoe body combined with an in-line wheel device can take wheels in the sole ordinarily for walking and running, and unfold wheels automatically when the user wants to take skating sport.

Abstract: The invention provides a creative latex based mainly vinyl acetate and one of methyl methacrylate, ethyl methacrylate or methyl acrylate, for non-hazardous use in shoe-making. A rigid liner can be made from said latex by any conventional technique wherein a base cloth such as a non-woven fabric is impregnated with said latex, and then the liner can be cut into shoe counter, toe and respective parts of shoe in any appropriate shape, characterized in that wherein said cut and shaped rigid liner is softened with alcohol and thereby produce adhesion, and then, the liner is inserted between the vamp and lining of the toe puff, counter and respective part of a shoe, bonds intimately and sets into fixed shape. Usage of the latex according to the invention in the shoe-making process can avoid serious hazard caused by the conventional latex that must use toluene as the solvent for softening.

Abstract: A kind of highly nondiaphanous nonowoven laminate consists of a inner black nontransparent lamina of non-thermoplastic long staple fibers and two outer laminae of thermoplastic fiber. It is processed through heating, press and bonding of the three laminae of fiber web together. Therefore, it possesses the properties of high nondiaphaneity, wrinkle resistance, good appearance and touch to hands and is very suitable for uses as screens, cover cloth and other non-transparent piece-goods.
