Fully flat slider

A device comprising:

• a lower panel with four sides, a first surface, and a second surface;
• an upper panel with four sides, a third surface, and a fourth surface, the fourth surface overlaying the first surface of the lower panel when the device is in a first configuration;
• a bi-stable shaft, a first end of the bi-stable shaft rotatably attached proximate to a first of the sides of the lower panel and a second end of the bi-stable shaft rotatably attached proximate to a first of the sides of the upper panel;
• a guide link having a first end, a second end, and a body connecting the first end to the second end, the first end rotatably attached proximate to the first side of the upper panel, the second end slidably inserted in a track located on the first side of the lower panel, and at least a part of the second end being slidable in parallel to the first face;
• and
• a spring positioned about the first end of the guide link, the spring applying torque to the guide link toward the fourth surface of the upper panel when a force is applied to a second of the sides of the upper panel to place the upper and lower panels in a flat configuration,
• wherein the first surface of the lower panel and the fourth surface of the upper panel are in a substantially same plane in the flat configuration, and
• wherein the device is in the flat configuration when the body is positioned parallel to the lower panel.

A device comprising:

• a first portion having a first surface and a track;
• a second portion having a second surface, the second portion overlaying the first portion when the device is in a first position;
• means for guiding the first surface, including a head, an interface portion, and a body connecting the head to the interface portion, the head rotatably affixed to the second portion and the interface portion being slidably retained in the track and at least a part of the interface portion being slidable in parallel to the first face;
• and
• means for moving the first portion relative to the second portion when force is applied to the second portion, the means for moving including a cam and a shaft rigidly connected to the cam, the cam rotatably affixed to the first portion and an end of the shaft rotatably affixed to the second portion,
• wherein
• when the device is in a second position between the first position and a bi-stable position, the shaft moves the second portion toward the first position,
• when the device is in a third position between the bi-stable position and a fully flat position, the shaft moves the second portion toward the fully flat position, and
• when the device is in the fully flat position, the first surface and the second surface are in a substantially same plane, and
• wherein the device is in the fully flat position when the body is positioned parallel to the first portion.
