Device configured to transport a human body
A device includes a main frame; at least one wheel; and supports. The supports are arranged in a support frame movably connected to the main frame. The support frame comprises a seat sub frame and a leg sub frame. The seat sub frame or the leg sub frame is fixedly hinged to the main frame, and the other is displaceably hinged to the main frame. A transformation mechanism associated with the main frame can convert the device between a planar support state and an angled support state. Supports enclose an angle to define a seat and backing support. The leg sub frame is extended beyond its hinge relative to the main frame and comprises a set of wheels at the free end of the extended leg sub frame. The extended leg sub frame provides a sturdy wheel base in the angled support state to define a wheel chair mode.
1. A device, comprising:
a main frame;
at least one wheel associated with the main frame;
supports;
wherein the supports are arranged in a support frame that is movably connected to the main frame;
wherein the support frame comprises a seat sub frame and a leg sub frame; and
wherein one of the seat sub frame and the leg sub frame is fixedly hinged relative to the main frame, and wherein the other of the seat sub frame and the leg sub frame is displaceably hinged relative to the main frame; and
a transformation mechanism associated with the main frame and configured to convert the device between a planar support state and an angled support state, wherein the supports enclose an angle to define a seat and backing support, and vice versa;
wherein, in the angled support state, the leg sub frame is extended to beyond its hinge relative to the main frame and comprises a set of wheels at the free end of the extended leg sub frame, and wherein the extended leg sub frame is configured to provide a sturdy wheel base in the angled support state to define a wheel chair mode.
2. The device according to claim 1 , wherein the support frame further comprises a backing sub frame that is displaceably hinged relative to the main frame.
3. The device according to claim 1 , wherein the main frame comprises two sub main frames that divide the main frame in two complementary halves.
4. The device according to claim 3 , wherein the sub main frames are at least one of pivotably and releasably connected.
5. The device according to claim 3 , wherein at least one of the supports comprises two support parts, wherein the support parts are each connected to one of the sub main frames of the main frame.
6. The device according to claim 5 , comprising a connection configured to connect two support parts of a support in at least the angled support state.
7. The device according to claim 1 , wherein the supports are pivotable relative to each other.
8. The device according to claim 1 , wherein the supports are moveable relative to the main frame.
9. The device according to claim 1 , wherein the support frame is slideable along the main frame.
10. The device according to claim 1 , further comprising wheels associated with the transformation mechanism to be exposed and operational in at least one of the planar support state and the angled support state, and to be inoperative and in a storing position in the other of the planar support state and the angled support state.
11. The device according to claim 10 , wherein the wheels associated with the transformation mechanism are exposed in the angled support state.
12. The device according to claim 10 , wherein the wheels associated with the transformation mechanism are arranged on the support frame.
13. The device according to claim 10 , wherein the transformation mechanism comprises a cam that forces the wheels into the exposed and operational state when the device is converted from the planar support state to the angled support state.
14. The device according to claim 1 , wherein the transformation mechanism comprises a lock configured to lock the supports relative to the main frame in at least one of the planar support state and the angled support state.
15. The device according to claim 1 , wherein the transformation mechanism comprises at least one slider that slidingly connects the support frame to the main frame.
