Martial arts training devices

Abstract

Martial arts training devices including a shoulder assembly, a first joint, a second joint, a first arm, a second arm, a first actuator, a second actuator, and a controller. The shoulder assembly includes a body. The first joint and the second joint are moveably supported on the body. The first arm is coupled to the first joint. The second arm is coupled to the second joint. The first actuator is configured to move the first joint to cause the first arm to simulate a first martial art strike. The second actuator is configured to move the second joint to cause the second arm to simulate a second martial art strike. The controller is operatively supported by the shoulder assembly and configured to selectively activate the first actuator and the second actuator.

         3 . The martial arts training device of  claim 2 , wherein the first arm simulates a human arm. 
     
     
         4 . The martial arts training device of  claim 3 , wherein:
 the body includes a first medial portion inset from the first lateral side; and   the second joint is moveably supported on the first medial portion of the body.   
     
     
         5 . The martial arts training device of  claim 4 , wherein:
 the body includes an upper portion; and   the second joint is moveably supported on the upper portion of the body.   
     
     
         6 . The martial arts training device of  claim 5 , wherein the second arm simulates a human arm. 
     
     
         7 . The martial arts training device of  claim 6 , wherein the first martial art strike is a horizontal side blow. 
     
     
         8 . The martial arts training device of  claim 7 , wherein the second martial art strike is an overhead downward blow. 
     
     
         9 . The martial arts training device of  claim 1 , further comprising a head pad simulating a human head mounted to the body an extending beyond an upper portion of the body. 
     
     
         10 . The martial arts training device of  claim 9 , wherein the head pad includes:
 a flexible neck coupled to the body and extending from the upper portion of the body; and   a head member mounted to the flexible neck.   
     
     
         11 . The martial arts training device of  claim 1 , further comprising a spine coupled to the shoulder assembly. 
     
     
         12 . The martial arts training device of  claim 11 , wherein:
 the spine includes a first end distal the shoulder assembly;   the spine includes a second end coupled to the shoulder assembly; and   the spine is configured to operatively couple to a vertical surface proximate the first end.   
     
     
         13 . The martial arts training device of  claim 12 , wherein the spine is bent between the first end and the second end to space the second end from the vertical surface to which the spine is operatively coupled. 
     
     
         14 . The martial arts training device of  claim 12 , further comprising a bracket selectively coupled to the spine proximate the first end and configured to selectively couple to the vertical surface. 
     
     
         15 . The martial arts training device of  claim 14 , wherein the bracket is configured to couple to the spine at different positions along the spine to adjust the effective height of the spine when the spine is coupled to the bracket. 
     
     
         16 . The martial arts training device of  claim 15 , wherein:
 the bracket defines a tunnel complementarily configured with the spine to enable the spine to extend through the tunnel;   the tunnel defines a height selection opening;   the spine defines a plurality of height option openings proximate the first end; and   the bracket includes a pin configured to extend through the height selection opening and a selected height option opening to selectively fix the position of the spine relative to the bracket.   
     
     
         17 . The martial arts training device of  claim 11 , further comprising a torso pad simulating a human torso coupled to the spine below the shoulder assembly. 
     
     
         18 . The martial arts training device of  claim 1 , wherein the first actuator is a servo motor. 
     
     
         19 . The martial arts training device of  claim 1 , further comprising:
 a third joint moveably supported on the body;   a third arm coupled to the third joint;   a third actuator configured to move the third joint to cause the third arm to simulate a third martial art strike;   a fourth joint moveably supported on the body;   a fourth arm coupled to the fourth joint; and   a fourth actuator configured to move the fourth joint to cause the fourth arm to simulate a fourth martial art strike.
