WHEELCHAIRS AND STRUCTURAL ELEMENTS THEREFOR

摘要

A structural assembly comprises an elongate member engaged to receive a receiving member. The elongate member has an external, non-circular cross-sectional shape with circumferentially spaced portions and further remaining portions between. The receiving formation has an internal cross-sectional shape which cooperates with the remaining portions to prevent relative longitudinal movement between the receiving member and the elongate member. Independent claims are also included for the following: (a) (i) a wheelchair including the above structural assembly; (b) (ii) a further structural assembly which includes a clamping means; (c) (iii) a cross-brace member (80, 81) for a wheelchair including at least one structural assembly; (d) and (iv) a further wheelchair including a cross-brace assembly (15).
