Title: Ergonomic Collapsible Handle

Description:
BACKGROUND OF INVENTION 
     Tablet personal computers (PCs) are an increasingly common convenience in modern lives. The quest of the technology industry to get them as thin and light as possible is driven by the fact that their form factor is not conducive to holding them for long periods of time. Regardless of how thin and light a tablet becomes, it will always be inconvenient to hold, especially as bezels become thinner and thinner. A new method for holding a tablet is needed. 
     A solution to the holding problem needs to be just as functional as grasping the tablet itself, while allowing maintaining or improving the utility and convenience of any device it&#39;s attached to. The present invention achieves this by offering the user a means of holding their tablet, or another object, comfortably and ergonomically, which also conveniently disappears when it is no longer needed. 
     Able to be built into a tablet&#39;s casing or attached to a tablet or other object via a case, or other method, this innovation will allow both the tablet industry and the accessory industry to further differentiate products and offer the consumer enhanced experiences and even greater health. 
     Though the innovation is conceptualized as providing ergonomic handles for a tablet PC, it is not limited to this use case. This innovation could easily be applied to other products to enhance their inherent functionality and convenience. Anything that would be enhanced by having a collapsible handle could benefit from having this innovation installed. 
     A great example of an alternate use is in the kitchen, with pot and pan lids. Currently, these lids have fixed, protruding, handles, which renders them impossible to stack so they are guaranteed to take up far too much space in one&#39;s cabinets. This innovation could solve that problem by allowing them to be stacked when stored. 
    
    
     
       BRIEF SUMMARY OF DRAWINGS 
         FIGS. 1 through 9  feature a preferred embodiment capable of forming a graspable protrusion along two different dimensional planes. It consists of 9 rigid sections connected to one another via attached hinged.  FIGS. 1-5  depict this preferred embodiment flat in its stored position, whereas  FIGS. 6-9  depict this preferred embodiment in its use position, ready to be grasped.  FIGS. 6 and 7  introduce directional markers to depict the embodiment in its use position along two directional planes.  FIGS. 1, 2, 6, and 7  depict this embodiment separate from its frame, and  FIGS. 3, 4, 5, 8, and 9  depict it within the track/rail of its frame. 
         FIGS. 10 through 14  depict an alternative preferred embodiment capable of forming a graspable protrusion along a single dimensional plane. This embodiment consists of 3 rigid sections designed to be connected to one another by sliding a pin through them, which, when done, forms a hinge.  FIGS. 10 and 13  feature this embodiment in its stored position while  FIGS. 11 and 14  feature this embodiment in its use position.  FIG. 12  depicts the frame and track/rail for this alternate embodiment.  FIGS. 10 and 11  depict this embodiment without a frame or track/rail, whereas  FIGS. 13 and 14  depict it within the track/rail of its frame.

     DESCRIPTION OF INVENTION AND DRAWINGS 
     The present invention consists of rigid sections (1.2 and 10.2) connected in such a way (1.3 and 10.3) that they can fold away from an object. Both embodiments pictured rely on hinges for this connection, but a flexible material could be substituted and still allow for the functioning of the device. In both pictured preferred embodiments, the four outermost corners of the rigid sections are shaped to form protrusions (1.1 and 10.1) designed to protrude under the frame (3.1 and 12.1) onto the rail and/or track (4.1 and 12.3). When the rigid sections are folded away, these protrusions slide along, and are constrained by, the track/rail, which forces the rigid sections to fold predictably into their use position and allows the device to remain connected to the frame and thereby to an attached object. 
     The frame and track/rail of the first preferred embodiment is designed to accommodate the same folding path of its rigid sections along two dimensional planes, whereas that of the alternate preferred embodiment is designed to accommodate the folding motion along a single dimensional plane. The depicted preferred embodiments of the track/rail are shown as a part of the frames of these embodiments, which would be secured to a surface of an object the user desires to grasp ergonomically (not pictured). When in the use position, the connected rigid sections create a grasp-able protrusion on the surface of an object (as pictured in  FIGS. 6, 7, 8, 9, 11 and 14 ). The present invention transfers forces from a grasping hand via the protrusions of the rigid sections to the frame and track/rail, which thereby transfers those forces to an attached object. 
     The first preferred embodiment of this invention would allow a user to hold an object in two orientations with the same ergonomic grip. For example, a tablet PC could be held in landscape or portrait mode while the user&#39;s wrist and hands remain in the same ergonomic positions. It is understood that the present invention is not limited to the described and pictured embodiments herein. For example, the shapes and sizes of the rigid sections could be altered, yielding a graspable protrusion of differing dimensions, which would still be graspable with the same grip from either the landscape or the portrait position of the tablet PC. Though specifically shaped rigid sections, protrusions, frames, tracks/rails, and hinges are pictured, it is understood that the present invention is not limited to these preferred embodiments, and that these elements can be changed so much as they still allow the utility of the present invention.
