Claim:
A convertible sled for use by a rider, and configured to convertibly use one or both of plural wheels in a first configuration and of plural sledding members in a second configuration, the convertible sled comprising: a body including a first side and a second side, a front portion, and a top surface configured to support the rider; a mounting unit coupled to the body for coupling one or both of the plural wheels in the first configuration such that the plural wheels are arranged along the first and second sides in pairs and of the plural sledding members in the second configuration such that the plural sledding members are arranged along the first and second sides in pairs; and a steering unit moveably coupled to the body at the front portion of the body such that, when the convertible sled is arranged in the first configuration, the steering unit is operatively coupled to at least two of the plural pairs of wheels, as steering wheels, for steering the convertible sled, the steering wheels on the first side of the body pivot about a first common point and the steering wheels on the second side of the body pivot about a second common point different from the first common point, and when the convertible sled is arranged in the second configuration the steering unit is operatively coupled to a portion of the plural pairs of sledding members for steering the convertible sled, wherein the portion of the plural pairs of sledding members define steering sledding members for steering the convertible sled such that, when the convertible sled is arranged in the second configuration, the steering sledding members on the first side of the body pivot about the first common point and the steering sledding member on the second side of the body pivot about the second common point, and the coupling unit comprises a crossbar projecting in opposite directions from the steering member one or more attachment units of a pivoting type each comprising: a mounting portion to mount one or both of the steering wheels and the steering sledding members, and an extension portion to pivotally couple with the crossbar at respective ends of the crossbar such that, as the steering member is moved in a direction extending from the first side to the second side, the steering wheels on the first side pivot about the first common point in a first rotational direction and the steering wheels on the second side pivot about the second common point in the first rotational direction and, as the steering member is moved in a direction extending from the second side to the first side, the steering wheels on the first side pivot about the first common point in a second rotational direction and the steering wheels on the second side pivot about the second common point in the second rotational direction.
