Abstract: The invention relates to an aerodynamic toy (1, 2) that has two concave portions (15 and 25 or 35 and 45), enabling the aerodynamic toy (1, 2) to be launched in any orientations. The aerodynamic flying toy has a central portion that is circular in form and circumscribed at its peripheral edge by a first annular flange curving upwardly laterally towards the centre of the central portion to form a first concave portion and by a second annular curving downwardly laterally towards the centre of the central portion (10) to form a second concave portion. The curved surface on the concave side of the annular flange of the aerodynamic flying toy can be further provided with a plurality of spaced apart ribs or ridges.

Abstract: An adjustable wrench or spanner is disclosed. It comprises essentially an elongated handle element with a convex urging portion at one end, an upper jaw element with a concave urging portion, a lower jaw element with a protrusion portion and a ratchet assembly. The upper jaw element is movable with the assistance of the two engaging urging portions and the lower jaw element is adjustable with the assistance of the ratchet assembly. Two jaw portions are operable in tightening or loosening positions, without having to be disengaged from a hexagonal nut. When the jaw portions are opened in a loosening position, gripping edges of the jaw portions are allowed to shift from one width across flats to another width across flats.

Abstract: An adjustable wrench or spanner is provided. It includes essentially an elongated handle element (1) with a convex urging portion (11) at one end, an upper jaw element (2) with a concave urging portion (21), a lower jaw element (4) with a protrusion portion (44) and a ratchet assembly (3). The upper jaw element (2) is movable with the assistance of the two engaging urging portions (11, 21) and the lower jaw element (4) is adjustable with the assistance of the ratchet assembly (3). Two jaw portions (22, 41) are operable in tightening or loosening positions, without having to be disengaged from a hexagonal nut. When the jaw portions (22, 41) are opened in a loosening position, gripping edges (23, 42) of the jaw portions (22, 41) are allowed to shift from one width across flats (f1) to another width across flats (f2).

Abstract: There is disclosed an extension socket device, electrically equipped with a plurality of socket units and a cord storage and dispensing system. The present invention comprises a rectangular housing body formed by two hollow parts, an electrical plug and an extension cord. The larger hollow part of the housing body comprises a top wall, two end walls and two side walls. The smaller hollow part comprises a ring-like intermediate wall and a bottom wall, wherein the intermediate wall and the bottom wall integrally form a working enclosure defining a working space for the wiring mechanism of the socket units. A receiving track of predetermined space is formed when the larger hollow part and the smaller hollow part are assembled together. The extension cord of predetermined length in single file is fully retracted into the receiving track. A plurality of flexible retainer means is integrally provided along the bottom edge of the smaller hollow part.
