A multiple directional wheel (10) including a wheel frame (20) comprising identical component parts (21i-ii). Each of the wheel frame components (21i-ii) comprise: a hub (30) having a main axis (1) about which the multiple directional wheel (10) is adapted to rotate; a hub rim (31) radially surrounding the hub (30); a first plurality (four shown) of peripheral roller supporting arms ("first arms") (22) radially extending from the hub rim (31) and aligned in a first plane; and a second plurality of peripheral roller supporting arms ("second arms") (23), each member arm of the second plurality of peripheral roller supporting arms having a radially inner base (24) and being circumferentially offset with respect to diagonally adjacent members of the first plurality of peripheral roller supporting arms (22). Each of the wheel frame components (21i-ii) further comprise a plurality of beams (25) corresponding to the number of member arms of the second plurality of peripheral roller supporting arms (23), each respective beam (25) extending from the hub rim (31) to a corresponding inner base (26) of a member arm of the second plurality of peripheral roller supporting arms (23), and a plurality of spigots (40) extending from each corresponding one the beams (25) or the inner bases (26). The second plurality of peripheral roller supporting arms (23) lie in a second plane normal to the main axis (1), spaced from, and parallel to, the first plane; and each of the spigots (40) from one of the wheel frame components (21i-ii) is received in a recess (27) formed in a facing surface (35) of a complementary one of the wheel frame components (21i-ii) to join the wheel frame components (21i-ii) to form the wheel frame (20). |
