Jacknife bed and couch for mobile vehicle
View Patent ↗A combination jackknife bed and couch for a mobile vehicle. The jackknife bed and couch allows drivers to wake up and fold their sheets and pillow away from a seamless sleeping surface without the need to remove the sheets, blankets, pillows or other bedding materials. The sheets stay made within the folded up bed now turned into the couch. The couch may be unfolded with the sheets fully made so the driver may catch some well deserved post socializing rest without having to re-install the sheets. These features are made possible by folding the bed in and half and keeping it in the backrest of the couch. The sheets are held in place by stretchable retaining surface that may be extended over the bedding materials. When returned to the bed mode, the stretchable retaining surface must be released and potential energy in the winder may be used to retract the retaining surface.
1. A combination jackknife bed and couch for a mobile motor vehicle, the vehicle having a sleeper compartment with a mounting floor, comprising:
a support base;
a sofa backrest and seat engaged to said support base;
said sofa backrest and said seat being hinged together through a hinge allowing said backrest and seat to be moved in a jackknife fashion relative to each other to enter either a couch or bed mode depending on a desired mode;
said seat slideable along said support base;
said seat containing a seat cushion as well as a rigid seat frame;
said backrest containing a seat cushion as well as a rigid backrest frame;
a mattress having a surface area roughly equal to the sum of the upper faces of said backrest and said seat when said jackknife bed and couch is in a bed mode;
said mattress covering both said backrest and said seat providing the user with a seamless sleeping surface;
an elastomeric cover rolled up under tension and mounted at a top of said backrest;
said elastomeric roll for covering a portion of said mattress sleeping surface and holding bedding materials in place against said mattress, allowing said mattress to be folded against said backrest;
said elastomeric cover unrollable via a rigid pole running a width of said combination bed and couch and said rigid pole being is attached to an exposed end of the fabric of said elastomeric roll;
said rigid pole hookable into a first hinging mechanism at the midpoint of said support base allowing said elastomeric cover to apply tension to against a seat cushion of said back rest and further allowing any bedding to be held in place when said backrest and said seat are jackknifed into a couch mode.
2. The combination jackknife bed and couch of claim 1 , wherein:
said first hinging mechanism is in a shape of a hook allowing one end of said rigid pole to be hooked with said elastomeric cover being under tension.
3. The combination jackknife bed and couch of claim 2 , wherein:
a second hinging mechanism on an opposite side of said first hinging mechanism so as to allow engagement of both ends of said rigid pole.
4. A mobile vehicle in combination with a combination jackknife bed and couch, comprising:
a cab engaged to a drive train bearing chassis;
a sleeper compartment including driver living space;
said sleeper compartment including a mounting floor;
a combination bed and couch support base engaged to said mounting floor;
a sofa backrest and seat engaged to said support base;
