Reciprocating rollator

A method comprising:

• providing a rollator, said rollator comprising
• a first side frame and a second side frame;
• said first side frame comprising a first side frame upper portion and a first side frame lower portion and a first side frame intervening structural portion;
• said second side frame comprising a second side frame upper portion and a second side frame lower portion and a second side frame intervening structural portion;
• plural first wheels disposed on said first side frame proximal said first side frame lower portion and plural second wheels disposed on said second side frame proximal said second side frame lower portion;
• a central platform having a first platform side and a second platform side;
• and
• first and second track mechanisms respectively coupling the first and second side portions to the first and second platform sides of the central platform;
• the first track mechanism comprising a first slot and first captive retainer configured to travel within said first slot, one of said first slot and first captive retainer being disposed on said first platform side and the other of said first slot and first captive retainer being disposed on said first side frame intervening structural portion;
• the second track mechanism comprising a second slot and second captive retainer configured to travel within said second slot, one of said second slot and second captive retainer being disposed on said second platform side and the other of said second slot and second captive retainer being disposed on said second side frame intervening structural portion;
• said first and second track mechanisms permitting independent movement of said first and second side frames relative to said central platform;
• grasping said first side frame and said second side frame;
• and
• while walking, manually reciprocating said first and second side frames relative to one another.

A rollator comprising:

• a left frame comprising:
• a left handle,
• a left arm coupled to the left handle,
• a left rail coupled to the left arm, wherein the left rail is oriented in a substantially horizontal orientation,
• a left front strut coupled to the left rail and extending toward a horizontal ground plane, and
• a left rear strut coupled to the left rail and extending toward the horizontal ground plane;
• a right frame comprising:
• a right handle,
• a right arm coupled to the left handle,
• a right rail coupled to the left arm, wherein the left rail is oriented in the substantially horizontal orientation,
• a right front strut coupled to the left rail and extending toward the horizontal ground plane, and
• a right rear strut coupled to the left rail and extending toward the horizontal ground plane;
• and
• a body frame sideably coupled to the right rail and allowing horizontal relative movement between the body frame and the right rail, and coupled to the left rail and allowing horizontal relative movement between the body frame and the left rail.

A method of using a rollator comprising:

• receiving a first forward force through a right handle;
• transferring the first forward force to a right frame through the right handle thereby translating the right frame in a forward direction;
• sliding the right frame relative to a body frame along a right track thereby moving the right frame forward relative to the body frame, and thereby moving the body frame forward relative to a left frame by sliding the body frame along a left track;
• stopping the receiving of the first forward force through the right handle;
• receiving a second forward force through a left handle;
• transferring the second forward force to the left frame through the left handle thereby translating the left frame in the forward direction;
• sliding the left frame relative to the body frame along the left track thereby moving the left frame forward relative to the body frame, and thereby moving the body frame forward relative to the right frame by sliding the body frame along the right track;
• stopping the receiving of the second forward force through the left handle.
