Abstract
A ride-along vehicle may include a guard that attaches to a bottom portion of a molded plastic body and covers a spring and chain assembly. The guard may also provide an attachment point for the spring through a hole in the guard. The guard may have a narrow portion that covers and helps retain the chain on a sprocket as well as a wider portion that covers the spring. An improved pumper arm and steering mechanism may include a pivot joint that is provided by rods, pins, or bolts attached to opposite sides of the pumper arm. The universal joint between the steering arm and the pumper arm can be aligned with the center of the pivot point to prevent rocking of the steering arm as the pumper arm is actuated.
Claims20
A pump-action ride-along vehicle comprising:
- a body providing a frame;
- a pumper arm pivotably connected to the frame at a pivot point;
- a steering arm having one end thereof connected to the pumper arm through a universal joint and having another end thereof connected to a steering mechanism arranged to control a direction of travel of the vehicle;
- a spring and chain assembly comprising a chain connected to an end of the pumper arm and a spring connected to the chain;
- a sprocket arranged on an axle and engaging the chain, wherein said sprocket is configured to cause rotation of the axle in response to actuation of the pumper arm;
- one or more wheels arranged on the axle;
- and
- a guard covering almost all of the spring and chain assembly such that only a small portion of the chain extends from a forward end of the guard to the pumper arm.
A ride-along vehicle comprising:
- a pump-action arm configured to provide movement to the vehicle when pumped;
- a spring and chain assembly connected to the pump-action arm at one end, said spring and chain assembly having a chain that engages a sprocket on an axle to provide rotational movement to the axle;
- and
- a guard covering a majority of the spring and chain assembly and the sprocket, wherein an opposite end of the spring and chain assembly is attached to the guard and where only a small portion of the chain extends from the guard to the pump-action arm.
A ride-along vehicle comprising:
- a frame;
- a pump arm pivotably connected to the frame at a pivot point;
- a steering arm connected to the pump arm through a universal joint, wherein the universal joint is aligned with a center of the pivot point;
- and
- a steering bar connected between the front wheels of the vehicle to turn the front wheels from side to side in response to turning of the pump arm, wherein an end of the steering arm is arranged within a hole in the steering bar, and wherein the hole is sized to closely fit the end of the steering arm so as not to permit any appreciable forward, backward, or lateral movement of the steering arm within the hole.
