Plank Position Exercising Apparatus

Abstract

A plank position exercising apparatus includes a base unit, a rotor unit, and at least one rotary member. The rotor unit is rotatably engaged with a spherical cavity of the base unit through the rotary member so that the user is able to perform plank circles through the plank position exercising apparatus. The user's feet are secured to the rotor unit during the performance of plank circles while the base unit moves in a circular direction via a plurality of wheel assemblies of the base unit. As a result, the user is able to use a full range of body motion to perform plank circles due to the configuration of the base unit, the rotor unit, and the rotary member.

         2 . The plank position exercising apparatus as claimed in  claim 1  comprises:
 the rotor unit comprises a support gimbal, a foot rest gimbal, a first rotational axis, and a second rotational axis; 
 the rotary member comprises a bearing and axle assembly; 
 the support gimbal being centrally positioned with the bearing and axle assembly about the first rotational axis; 
 the support gimbal being rotatably connected to the base unit through the bearing and axle assembly; 
 the foot rest gimbal being concentrically positioned with the support gimbal about the second rotational axis; and 
 the foot rest gimbal being rotatably connected to the support gimbal. 
 
     
     
         3 . The plank position exercising apparatus as claimed in  claim 2  comprises:
 the support gimbal comprises a connecting member, a first pivot arm, and a second pivot arm; 
 the first pivot arm and the second pivot arm being diametrically opposed of each other along the connecting member; and 
 the first pivot arm and the second pivot arm being adjacently connected to the connecting member. 
 
     
     
         4 . The plank position exercising apparatus as claimed in  claim 2  comprises:
 the foot rest gimbal comprises a base plate, a lateral wall, a first lateral support, a second lateral support, a layer of formfitting material, and a pair of strap fasteners; 
 the lateral wall being perimetrically connected around the base plate; 
 the first lateral support and the second lateral support being diametrically opposed of each other along the base plate; 
 the first lateral support and the second lateral support being adjacently connected to the lateral wall, opposite of the base plate; 
 the layer of formfitting material being superimposed over the base plate; 
 the pair of strap fasteners traversing through the layer of formfitting material; and 
 the pair of strap fasteners being adjacently connected to the base plate. 
 
     
     
         5 . The plank position exercising apparatus as claimed in  claim 2  comprises:
 a connecting member of the support gimbal being rotatably connected to the base unit through the bearing and axle assembly, about the first rotational axis; 
 a first lateral support of the foot rest gimbal being rotatably connected to a first pivot arm of the support gimbal, about the second rotational axis; and 
 a second lateral support of the foot rest gimbal being rotatably connected to a second pivot arm of the support gimbal, about the second rotational axis. 
 
     
     
         6 . The plank position exercising apparatus as claimed in  claim 1  comprises:
 the rotor unit comprises a spherical housing, an access opening, and a plurality of formfitting members; 
 the rotary member comprises a plurality of ball units; 
 the plurality of ball units being connected to the spherical cavity; 
 each of the plurality of ball units being evenly spaced apart of each other; and 
 the spherical housing being pivotally engaged to the base unit through the plurality of ball units. 
 
     
     
         7 . The plank position exercising apparatus as claimed in  claim 6  comprises:
 the access opening traversing into the spherical housing; and 
 the plurality of formfitting members being internally connected to the spherical housing. 
 
     
     
         8 . The plank position exercising apparatus as claimed in  claim 6  comprises:
 each of the plurality of ball units comprise a stator portion and a rotor portion; 
 the rotor portion being rotatably engaged with the stator portion; 
 the stator portion being connected to the base unit; 
 the stator portion being positioned flush with the top surface of base unit; 
 the rotor portion being adjacently positioned with the spherical cavity; and 
 the rotor portion being externally engaged with the spherical housing.
