Step auto clay thrower
First Claim
1. A step auto clay thrower, comprising:
- a base;
a stepping rod having a front end thereof pivotally connected to a front side of said base by a first pivot member, an opposing rear end thereof connected with a pedal, said pedal being connected to one end of a first connecting member that has an opposite end thereof connected to one end of a first spring, said stepping rod having a front part thereof connected with a tilting bracket, said tilting bracket being connected to one end of a second spring through a second connecting member, said second spring having an opposite end thereof connected to one end of a link;
a support affixed to a front top side of said base;
a throwing arm holder mounted on a top side of said support, said throwing arm holder comprising a first bearing block located at a front side thereof, a shaft movably coupled to said first bearing block with a bottom end thereof connected with a first linking member, said first linking member being pivotally connected to an opposite end of said link by a second pivot member, said throwing arm holder having a back side thereof pivotally connected with a trigger arm by a third pivot member, said trigger arm having a bottom end thereof connected to an opposite end of said first spring;
a throwing arm having a coupling groove located on a front side thereof and connected with a third connecting member that is fixed connected with a top side of said shaft by welding, a rear top side configured for the placement of a clay, a rear side of a sidewall thereof for stopping by a top side of the trigger arm; and
a mini motor having a motor shaft coupled with said shaft for rotating said shaft to return said throwing arm.

Abstract
A step auto clay thrower consisting of a base, a stepping rod, a support, a throwing arm holder, a throwing arm and a mini motor is disclosed. When the stepping rod is depressed, the throwing arm is forced by a second spring to move a link and a first linking member in turning a shaft and a throwing arm forward for causing generation of a centrifugal force to throw a clay away from the throwing arm, and then a motor shaft of the mini motor is driven to rotate the shaft, thereby returning the throwing arm without any manual operation. In the time the throwing arm throws the clay and the throwing arm is returned by the mini motor, the mini motor does not need to overcome the force of the second spring so that the capacity of the mini motor can be minimized.
