Training apparatus

Abstract

An apparatus, system, and method are disclosed for a training apparatus. The apparatus includes a first member, a second member, and a biasing member. The first member has a concave engagement end opposite an extension end. The concave engagement end includes a recess defining an at least partially spherical engagement receiving space. The second member includes a convex engagement end disposed opposite an extension end. The convex engagement end has a substantially convex surface which is matingly receivable within the engagement receiving space of the first member. The biasing member is engaged with the first member and biases the engagement receiving space of the first member in a mating engagement within the convex engagement end of the second member. The convex engagement end of the second member is laterally displaceable from within the engagement receiving space in the first member in response to a displacing pressure.

What is claimed is: 
     
         1 . A training apparatus comprising:
 a first member comprising a concave engagement end disposed opposite an extension end, the concave engagement end comprising a recess having a substantially concave surface defining an engagement receiving space, wherein the engagement receiving space is at least partially spherical;   a second member comprising a convex engagement end disposed opposite an extension end, the convex engagement end having a substantially convex surface, wherein the substantially convex surface is at least partially spherical, the convex engagement end of the second member matingly receivable within the engagement receiving space of the first member;   a biasing member engaged with the first member, the biasing member biasing the engagement receiving space of the first member in a mating engagement within the convex engagement end of the second member; and   wherein the convex engagement end of the second member is laterally displaceable from within the engagement receiving space in the first member in response to a displacing pressure applied to one of the first member and the second member.   
     
     
         2 . The apparatus of  claim 1 , wherein the biasing member is coupled to a coupling member at a first end of the biasing member, the coupling member extending through a first orifice disposed through the first member and a second orifice disposed through the second member, wherein the coupling member engages the first member to bias the convex engagement end of the second member within the engagement receiving space of the first member. 
     
     
         3 . The apparatus of  claim 2 , wherein at least one of the first orifice and the second orifice has an axial area sufficient to allow lateral displacement of the first member with respect to the second member without interfering with the coupling member. 
     
     
         4 . The apparatus of  claim 2 , further comprising a supporting member and a base member, the supporting member positioned between the base member and the second member with the base member supporting the supporting member, wherein the biasing member biases the first member in a direction of the supporting member. 
     
     
         5 . The apparatus of  claim 4 , wherein the biasing member is coupled to a base member that is engaged with a floor surface. 
     
     
         6 . The apparatus of  claim 4 , wherein the base member is weighted. 
     
     
         7 . The apparatus of  claim 1 , wherein a biasing force of the biasing member is adjustable and wherein adjustment of the biasing force adjusts the displacing pressure required to laterally displace the convex engagement end of the second member is from within the engagement receiving space. 
     
     
         8 . The apparatus of  claim 1 , further comprising a protective membrane covering the first member and the second member, the protective membrane protecting an appendage of a user when the displacing pressure is applied to one of the first member and the second member. 
     
     
         9 . The apparatus of  claim 8 , wherein the protective membrane comprises a material having a durometer sufficient to absorb a blow from a user without injuring the user. 
     
     
         10 . The apparatus of  claim 9 , wherein the protective membrane comprises a shape substantially similar to at least a portion of a human. 
     
     
         11 . The apparatus of  claim 1 , further comprising a frame structure and a protective membrane, the frame structure coupled to the first member, wherein the frame structure comprises at least one extending member extending to a height of approximately an average adult's chest, the frame structure supporting the protective membrane, the protective membrane comprising a shape substantially similar to an adult's chest, torso, and legs.
