Abstract
The disclosed device is a wheelchair that is capable of being converted into a bed and visa versa. The device is also able to transfer patients from it unto another surface, such as a bed or an examination table. The device may be used as a rescue apparatus to lift patients that fell on the ground. The mobility device may additionally have hygienic openings to enable a rider to relieve him or herself without needing to be lifted or transferred off the mobility device. The device is fully motorized, with all functions capable of being performed at the touch of a button.
Claims19
A mobility device comprising:
- a pair of first struts, said pair of first struts being in a parallel and set apart association with each other;
- each strut of said first pair of struts having a main wheel rotatingly attached thereto;
- wherein said main wheel supporting said strut that is rotatingly connects to a support surface;
- a pair of second struts, said pair of second struts being in a parallel and set apart association with each other;
- each strut of said second pair of struts having a main wheel rotatingly attached thereto;
- wherein said main wheel supporting said strut that is rotatingly connects to a support surface;
- wherein said pair of first struts and said pair of second struts are in a parallel and set apart association with each other;
- at least two ties;
- wherein a first of said at least two ties connecting to one strut of said first pair of struts and to one strut of said second pair of struts;
- and wherein a second of said at least two ties oriented in a parallel and set apart orientation with said first tie of said at least two ties connecting the other strut of said first pair of struts and the other strut of said second pair of struts;
- wherein said first and said second ties forming a lengthwise side;
- each strut of said second pair of struts comprised of hollow telescoping components;
- and wherein said first tie and said second tie of said at least two ties comprised of hollow telescoping components;
- a support frame;
- said support frame comprising a first plurality of frame components and a second plurality of frame components;
- said first plurality of frame components and said second plurality of frame components having a first frame component and at least one forward frame component;
- wherein each said first frame component and each said at least one forward frame component having a first end and a second end;
- wherein said first plurality and said second plurality of frame components being in a parallel and spaced apart association with each other;
- wherein said first end of each first frame component and each at least one forward frame component having a rotatable joint;
- wherein each said rotatable joint of the first plurality of frame components rotatingly coupling the opposing and parallel rotatable joint of the second plurality of frame components;
- wherein one of said axles that rotatingly couples with the first end of the first frame component of the first plurality of frame components and with the first end of the first frame component of the second plurality of frame components being a first main axle and wherein a frontmost axle of said axles forming a second main axle;
- wherein the second end of said first frame component of the first and second plurality of frame components in a slidable and telescoping association with said at least one forward frame component;
- a rear frame component of said first plurality of frame components and a rear frame component of said second plurality of frame components further comprising secondary frame components;
- said rear frame component of said first plurality and said second plurality of frame components having a distal end and a proximal end;
- wherein said distal of each said rear frame component being in slidable and telescoping association with said at least one secondary frame component;
- and wherein a distal end of a rearmost of said of said secondary frame components of said rear frame component of said first plurality of frame components rotatingly connected via a rearmost axle to said distal end of a rearmost secondary frame component of said second plurality of frame components;
- and wherein said proximal end of said rear frame component of said first plurality of frame components connected through a rear hinge to said first end of said first frame component of the first plurality of frame components, and wherein said proximal end of said rear frame component of said second plurality of frame components connected through a rear hinge to said first end of said first frame component of the second plurality of frame components;
- wherein said first main axle connecting said struts of the first pair of struts;
- said first main axle functioning as a rear pivot for said rear hinge of said first plurality of frame components and said rear hinge of said second plurality of frame components;
- said rear hinge having a rotary actuator, said rotary actuator connecting to at least one of said rear frame components and at least one of said first frame components;
- a second main axle connecting struts of said second pair of struts, said second main axle insertedly connecting through said second end of the a forwardmost of said at least one forward frame component of the first and second plurality of frame components;
- wherein said second main axle forming a front pivot;
- a belt, said belt wrapping in a closed loop between a secondary axle and said second main axle;
- and wherein said belt passing beneath a retention bracket adjacently to said rear pivot.
