1. A walker to assist a person rising from a seated position, said walker comprising: two front legs each having a proximal end, a center and a distal end;one or more cross members secured to and joining said front legs to one another;a handle engaged to the proximal end of each front leg;a joint mechanism engaged to each front leg; andtwo rear legs having a proximal end and a distal end, said proximal end being engaged to each joint mechanism allowing said rear legs to pivot relative to said front legs; wherein said joint mechanism is comprised of: a bearing which includes a socket;a tongue end fitting engaged with said bearing;one or more clevis type connectors secured to said bearing and said tongue end fitting;a housing surrounding said bearing, said tongue end fitting and said clevis type connectors, wherein said bearing pivotally rotates within said housing and said tongue end fitting extends out of said housing; said rear leg is engaged to said tongue end fitting;a support release pin assembly secured to said housing and operating with said socket; anda trigger lever operating with said support release pin which, when actuated, withdraws said pin from said socket, allowing said support release pin assembly to secure said bearing and said rear legs in a standing configuration or to release said bearing and allow said bearing and said rear legs to be secured in a kneeling configuration. 2. The walker of claim 1 further comprising a wheel assembly secured to the distal ends of each front leg. 3. The walker of claim 1 wherein the handles are telescopically engaged to the front legs and each handle and front leg further include a height adjustment mechanism which allow the height of the handles to be individually adjusted to a height desired by a user. 4. The walker of claim 1 wherein said rear legs each further include a locking mechanism which, when disengaged, allows for each rear leg to be rotated to configure the walker into a more compact form. 5. The walker of claim 1 wherein said handle further comprises: a primary projection extending in the same general direction as said rear legs that serves as a primary handle;a secondary projection extending at an upward angle from the primary projection that serves as a secondary handle; anda grip secured to said secondary projection. 6. A walker to assist a person rising from a seated position, said walker comprising: two front legs each comprising a proximal end, a center and a distal end, wherein each front leg comprises a handle mounting tube at a proximal end, and wheel mounting tube at a distal end;a wheel secured to said wheel mounting tube;one or more cross members secured to and joining the front legs to one another;a handle engaged to said handle mounting tube of each front leg;a joint mechanism engaged to the center of each front leg, separating said handle mounting tube from said wheel mounting tube; andtwo rear legs having a proximal end and a distal end, said proximal end being engaged to each joint mechanism allowing said rear legs to pivot relative to said front legs; wherein the joint mechanism is comprised of: a bearing which includes a socket;a tongue end fitting engaged with said bearing;one or more clevis type connectors secured to said bearing and said tongue end fitting;a housing surrounding said bearing, said tongue end fitting and said clevis type connectors, wherein said bearing pivotally rotates within said housing and said tongue end fitting extends out of said housing; said rear leg is engaged to said tongue end fitting;a support release pin assembly secured to said housing and operating with said socket; anda trigger lever operating with said support release pin which, when actuated, withdraws said pin from said socket, allowing said support release pin assembly to secure said bearing and said rear legs in a standing configuration or to release said bearing and allow said bearing and said rear legs to be secured in a kneeling configuration. 7. The walker of claim 6 wherein the handles are telescopically engaged to the handle mounting tube and each handle and handle mounting tube further include a height adjustment mechanism which allow the height of the handles to be individually adjusted to a height desired by a user. 8. The walker of claim 6 wherein said rear legs further each include a locking mechanism which, when disengaged, allows for each rear leg to be rotated to configure the walker into a more compact form. 9. The walker of claim 6 wherein said handle further comprises: a primary projection extending in the same general direction as said rear legs that serves as a primary handle;a secondary projection extending at an upward angle from said primary projection that serves as a secondary handle; anda grip secured to said secondary projection.
