Abstract

A bed comprising a bottom platform for securing to a surface of a vehicle and a horizontal riding platform coupled to the bottom platform by a horizontal motion interface which allows relative horizontal movement between the horizontal riding platform and the bottom platform. A top platform is coupled to the horizontal riding platform by a frame assembly which allows relative vertical movement between the top platform and the horizontal riding platform, such that the top platform is moveable between a lowered position and a raised position. A biasing mechanism is located between the top platform and the horizontal riding platform for selectively biasing the top platform toward the raised position.

Claims

1. A bed comprising:

a bottom platform for securing to a surface of a vehicle;

a horizontal riding platform coupled to the bottom platform by a horizontal motion interface which allows relative horizontal movement between the horizontal riding platform and the bottom platform;

a top platform coupled to the horizontal riding platform by a frame assembly which allows relative vertical movement between the top platform and the horizontal riding platform, such that the top platform is moveable between a lowered position and a raised position; and

,

a biasing mechanism located between the top platform and the horizontal riding platform for selectively biasing the top platform toward the raised position.

2. A bed according to claim 1 wherein the biasing mechanism comprises at least one airbag operatively coupled to a pressurized air source.

3. A bed according to claim 1 wherein the biasing mechanism comprises at least two airbags, each airbag operatively coupled to an associated pressurized air source, the bed further comprising a controller for selectively adjusting the pressure of air provided from each pressurized air source to the associated airbag.

4. A bed according to claim 1 wherein the horizontal motion interface comprises a plurality of bearing assemblies.

5. A bed according to claim 4 wherein each bearing assembly comprises a lower ring attached to the bottom platform, an upper ring attached to the horizontal riding platform, and a bearing contained between the lower ring and the upper ring.

6. A bed according to claim 5 wherein the horizontal motion interface comprises a lower bracket attached to the bottom platform and an upper bracket attached to the horizontal riding platform, wherein the lower bracket interlocks with the upper bracket to prevent the bottom platform and the horizontal riding platform from being separated more than a predetermined distance in the vertical direction.

7. A bed according to claim 4 wherein the horizontal motion interface comprises a plurality of springs connected between the bottom platform and the horizontal riding platform for biasing the horizontal riding platform towards a neutral position.

8. A bed according to claim 1 comprising a cover attached between outer edges of the top platform and the bottom platform.

9. A bed according to claim 1 wherein the bed is separable into at least two sections to facilitate installation, each section comprising a bottom platform section, a horizontal riding platform section and a top platform section.

10. A bed according to claim 9 comprising a cover section corresponding to each section of the bed, each cover section attached between outer edges of the corresponding top platform section and bottom platform section.

11. A bed according to claim 10 wherein the cover sections are joinable together by at least one section interface.

12. A bed according to claim 10 wherein each cover section defines an access slit for facilitating attachment of the sections of the bed to each other.
