Abstract: A multi-terrain cart, comprising a cart body, two front and two rear non-pivoting wheels, a swivel wheel positioned forwardly or rearwardly to the front and rear non-pivoting wheels, respectively, an actuator for applying a downward force to the swivel wheel which causes the swivel wheel to be set at an operative position and two of the non-pivoting wheels to be raised relative to an underlying ground surface, and means for setting an angle of the swivel wheel relative to a lengthwise extending centerline of the cart body to cause the cart to rotate about a center of rotation that is determined by the set angle of the swivel wheel.

Abstract: The invention is a bicycle having adjustable orientation of the seat (6) and the pedals (4) with respect to the handle-bars (5). The bicycle comprising an x shaped frame comprised of a profile (31) and a rigid support member (32) that are rotatably connected to each other by a hollow pin (42). The rider of the bicycle can change the angle between the profile (31) and the rigid support member (32) to rotate about the hollow pin (42). The bicycle further comprises a seat (6), attached to the upper part of the rigid support member (32), a first toothed-wheel (33) attached to the frame (32) by means of a pin passing through the toothed-wheel (33) and the lower part of the rigid support member (32). The pin has a crank and pedal (4) attached to each of its ends. The bicycle also comprises a front gear and second toothed-wheel (7) attached to a pin that passes through the hollow pin (42) located between the seat (6) and the first toothed-wheel (33).

Abstract translation: 本发明是一种具有座椅（6）和踏板（4）相对于把手杆（5）的方向可调节的自行车。 所述自行车包括由轮廓（31）和刚性支撑构件（32）组成的x形框架，所述轮廓（31）和通过中空销（42）彼此可旋转地连接的刚性支撑构件（32）。 自行车的骑手可以改变轮廓（31）和刚性支撑构件（32）之间的角度，围绕中空销（42）旋转。 所述自行车还包括附接到所述刚性支撑构件（32）的上部的座（6），通过穿过所述齿轮的销的第二齿轮（33）附接到所述框架（32） （33）和刚性支撑构件（32）的下部。 销具有连接到其每个端部的曲柄和踏板（4）。 所述自行车还包括前齿轮和第二齿轮（7），所述第二齿轮（7）附接到穿过所述座（6）和所述第一齿轮（33）之间的所述中空销（42）的销。
