Martial arts training device

A martial arts training device comprising:

• a base assembly having a top;
• a primary spring affixed to the top of the base assembly, the primary spring having a top and a bottom;
• a torso body assembly;
• a vertical adjustment assembly adapted to vertically translate the torso body assembly between a downward position and an upward position;
• and
• at least one bidirectional spring-biased assembly for yieldably maintaining the torso body assembly in a default resting position, the at least one bidirectional spring-biased assembly operably connected to a point above the primary spring and a fixed point behind the martial arts training device, the at least one bidirectional spring-biased assembly comprising:
• a cylinder body having a proximal end and distal end;
• a rod having a length having an axis, proximal end, a distal end, and a longitudinal slot extending a segment of the length, the rod is reciprocable within the cylinder body, the proximal end of the rod is exposed exterior of the cylinder body, the distal end of the rod terminating at a point within the cylinder body;
• a piston affixed to the distal end of the rod;
• at least one rearward countering spring for countering an external force applied to the torso body assembly in the rearward direction, the at least one rearward countering spring operably restrained between the piston and the distal end of the cylinder body;
• and
• at least one forward countering spring for countering an external force applied to the torso body assembly in a forward direction, the at least one forward countering spring operably restrained between the proximal end of the cylinder body and the piston.

A martial arts training device comprising:

• a base assembly having a forward end, a rear end, and a top extending between the forward end and the rear end, the base assembly adapted to be positioned on a ground surface;
• a primary spring having a bottom and a top, the bottom of the primary spring affixed to the top of the base assembly;
• a torso body assembly constructed partially of a padding and having a head portion;
• a vertical adjustment assembly positioned below the torso body portion and adapted to vertically translate the torso body portion between a downward position and an upward position, the vertical adjustment assembly comprising:
• a cap assembly affixed to the top of the primary spring, the cap assembly comprising a vertical screw through hole having threads and one or more axial bearings;
• a linear screw having a lower end and an upper end, the lower end operably engaging the screw through hole of the cap assembly, the upper end of the linear screw having a means to rotate which is exposed at the rear of the torso body portion;
• one or more guide rods radially disposed about the linear screw, each of the one or more guide rods operably coupled with the respective one or more axial bearings of the cap assembly, each of the one or more guide rods having a lower end;
• and
• a limiting connection member attaching the lower ends of the linear screw and each of the one or more guide rods, wherein the limiting connection member limits the vertical adjustment assembly at the upward position;
• and
• at least one bidirectional spring-biased assembly for yieldably maintaining the torso body assembly in a default resting position, the at least one bidirectional spring-biased assembly comprising:
• at least one selector pin;
• a cylinder housing assembly comprising:
• a cylinder body having a proximal end and a distal end, the cylinder body having a least one set of lateral selector holes adapted to selectively receive the at least one selector pin,
• a proximal housing cap coupled to the proximal end of the cylinder body, the proximal housing cap having an interior surface, and
• a distal housing cap operably coupled to the distal end of the cylinder body, the distal housing cap having an interior surface;
• a rod having a longitudinal length and a longitudinal axis, proximal end, a distal end, and a slot extending a segment of the longitudinal length adapted to receive the at least one selector pin laterally therethrough, the rod is reciprocable within the cylinder housing assembly, the proximal end of the rod is exposed exterior of the cylinder body and is operably hingedly attached to the cap assembly, the distal end of the rod terminating at a point within the cylinder body;
• a piston affixed to the distal end of the rod, the piston having a radial disk having opposing proximal and distal surfaces which are perpendicular to the rod longitudinal axis;
• at least one rearward countering spring for countering an external force applied to the torso body assembly in the rearward direction, the at least one rearward countering spring operably restrained between the piston distal surface and the interior end of the distal housing cap;
• a plurality of forward countering springs for countering an external force applied to the torso in a forward direction, the plurality of forward countering springs contiguously aligned and restrained between the proximal housing cap and the piston proximal surface;
• and
• one or more spacer assemblies for separating each of the plurality of forward countering springs from each other each of the one or more spacer assemblies having a lateral channel and a longitudinal shaft, the longitudinal shaft adapted to translate the rod freely therethrough and the lateral channel configured to align with the longitudinal slot of the rod and the respective set of lateral selector holes of the cylinder body while in the default resting position, thereby the rod longitudinal slot, the spacer lateral channel and the respective set of lateral selector holes are collectively aligned and configured to receive the selector pin therethrough while in the default resting position;
• wherein the distal end of each of the bidirectional spring-biased assemblies are hingedly connected to the rear end of the base assembly.
