<p>A stabiliser system, primarily for supporting a pedal bicycle and its rider upright at the halt, comprises a spring-loaded telescopic arm (26) which is connected at its upper end by a pivot (21) adjacent the rear wheel spindle (12) to a bracket secured to the spindle (12). A bolt (31) pivoted to the bracket engages the gusset plate (13) to resist clockwise motion of the bracket and a gas strut (28) extends between the bracket and the arm (26). At the lower end of the arm (26) is a cross-shaft (33) carrying stabiliser wheels (34, 35). The arm can be lowered by a cable (46) to move a roller (36) on the cross-shaft beneath the tyre of the wheel (11) so that a large part of the weight of the rider is transferred to the ground through the rear wheel (11), the roller (36), the cross-shaft (33) and the stabiliser wheels (34, 35). The cable (46) is in the form of a closed loop and passes around a guide (41) on the cross-shaft, around tapered guide pulleys (77) carried by a dependent bracket (62) within which is pivoted an arm (53) carrying a shaft (56) on which there is a tyre-engaging wheel (57) and two spools (58). The bracket (62) contains a cam (67) which can be operated from the handlebars via a Bowden cable (75). To lower the arm (26), the wheel (57) is moved by the cam into engagement with the tyre of the bicycle wheel (11) to rotate the spools (58) and draw in the cable (46).</p> |
