Abstract
An inflatable bed having a primary body, a backrest selectively inclinable relative to the primary body, a slit defined at a junction of the primary body and the backrest, and a pouch received in the slit to be selectively inflatable to move the backrest relative to the primary body. The slit is defined in a manner that when the pouch is inflated and the backrest is lifted by the pouch, friction of a bottom face of the backrest to a top face of ground where the inflatable bed is rested is minimized so as to facilitate the inclinable movement of the backrest relative to the primary body.
Claims20
An inflatable bed comprising:
- a primary body having a bottom face;
- a backrest having a bottom face, wherein the backrest is selectively inclinable relative to the primary body;
- a slit defined at a junction of the primary body and the backrest;
- and
- a pouch received in the slit to be selectively inflatable to move the backrest relative to the primary body, wherein the slit extends from the bottom faces of the primary body and the backrest, and wherein the bottom faces of the primary body and the backrest are co-planar when the primary body and the backrest are inflated and the pouch is deflated.
An inflatable bed comprising:
- a primary body;
- a backrest selectively inclinable relative to the primary body;
- a slit defined at a junction of the primary body and the backrest;
- and
- a pouch received in the slit to be selectively inflatable to move the backrest relative to the primary body, wherein the slit is defined in a manner that when the pouch is inflated and the backrest is lifted by the pouch, friction of a bottom face of the backrest to a top face of ground where the inflatable bed is rested is minimized so as to facilitate the inclinable movement of the backrest relative to the primary body,
- wherein each of the backrest and the primary body has a top, a bottom and a skirt respectively connecting a peripheral edge of the top to a peripheral edge of the bottom to form an air-tight enclosure.
An inflatable bed comprising:
- a primary body;
- a backrest selectively inclinable relative to the primary body;
- a slit defined at a junction of the primary body and the backrest;
- and
- a pouch received in the slit to be selectively inflatable to move the backrest relative to the primary body, wherein the slit is defined in a manner that when the pouch is inflated and the backrest is lifted by the pouch, friction of a bottom face of the backrest to a top face of ground where the inflatable bed is rested is minimized so as to facilitate the inclinable movement of the backrest relative to the primary body, wherein the pouch is connected to at least the primary body or the backrest.
