ABSTRACT:
A cushioned braking system for cushioning the impact of a moving vehicle for amusement for children. The braking system comprises a double ended air cylinder having a first cylinder end and a second cylinder end. A first head member and a second head member close the first and second cylinder ends, respectively. A first piston rod extends axially outward from the cylinder through the first head member. A first piston is on the first piston rod within the cylinder. A second piston rod extends axially outward from the cylinder through the second head member. A second piston is on the second piston rod within the cylinder. A spring assembly resiliently connects the first piston to the second piston within the cylinder. The spring assembly serves to bias the first and second pistons toward a reference position. The cylinder also has a vent for controlling air flow within the cylinder. Contact between a piston rod and a stop causes said piston rod to be forced axially into the cylinder, thereby partially compressing the air in the cylinder and compressing the spring assembly. The spring assembly serves to bias the rod axially outward after the spring assembly has been compressed.
