Abstract
A sledge with ski-like runners, which are mounted on bracket-like transverse connecting members by means of inclined tilt axes. The runners are tilted in the same direction when travelling along inclined ground or when riding round curves the runners being simultaneously displaced longitudinally relative to one another. A seat is mounted on the connecting members and is thereby displaced and inclined. The runners can be mounted in a light ploughing position and with a pre-tilting, so that the runners in the neutral or straight position will run on their inner edges.
Claims30
A sledge, comprising:
- at least two runners defining a longitudinal axis of the sledge;
- at least two connecting members having joints at each end for interconnecting the runners;
- and,
- at least one of the joints on each runner having means defining a tilt axis inclined in a generally vertical plane, each tilt axis providing compound rotational components, whereby upon relative rotational movement of the runners and at least one of the connecting members about effective vertical axes, during which the tilt axis means of the respective runners necessarily move in opposite longitudinal directions together with the runners relative to one another, the runners simultaneously tilt about effective horizontal axes.
