A stabilizing mechanism for a two part foldable hinged device having a cover and a base is disclosed and includes at least one elastic member having one end attached to the cover and a second opposite end attached to the base. The elastic member has a bending section defined between the ends which extends to increase the contact surface area of the base as the cover pivots open with respect to the base to keep the device from tipping over when the device is placed on a resting surface. The bending section is formed between two spaced apart knuckles whereby the elastic member bends with a controlled variable displacement to provide a greater rate of available contact surface as the cover and base pivot relative to one another, particularly between 90° and 180°. A portion of the second opposite end of the elastic member may extend beyond the downwardly facing surface of the base to make contact with the resting surface to prevent the device from sliding on the surface.

The invention claimed is: 1. A foldable device, comprising: a first part; a second part; a hinge; said first and second parts hingedly connected to one another and arranged for pivotal movement with respect to one another about a longitudinal folding axis passing through said hinge, said first and second parts pivoting from a closed folded position through a pre-determined angular range to an open position, wherein said foldable device is configured in an infinite number of stable operative positions through the pre-determined angular range; and a stabilizing mechanism including at least one elastic member having one end fixedly attached to said first part and an opposite end fixedly attached to said second part, said elastic member having a bending section defined between said first and second ends and transverse to the longitudinal folding axis, such that said pivotal movement of said first part with respect to said second part causes said bending section to extend a proportional distance beyond a plane substantially perpendicular to the major face surfaces of said first and second parts and passing through said longitudinal folding axis as said first part is pivoted through said pre-determined angular range to provide an increasing contact surface area to keep the device from tipping over when the device is placed on a resting surface, wherein said bending section is formed between two spaced apart knuckles such that said elastic member bends with a controlled variable displacement to provide a greater rate of available contact surface as said first and second parts pivot relative to one another, said two spaced apart knuckles comprising a first knuckle located nearest said first part and a second knuckle located nearest said second part, said first knuckle having a dimension that is thinner than a dimension of said second knuckle such that the first knuckle deforms and bends at a faster rate than the second knuckle when the first part pivotably moves from said open position to said closed position. 2. The foldable device as defined in claim 1 wherein said first and second parts pivot relative to one another between 90° and 180°. 3. The foldable device defined in claim 1 wherein said first part is a cover portion and said second part is a base portion, said base portion having a downwardly facing surface contact area and at least one lengthwise groove located in a spaced relation with a first side marginal edge and second side marginal edge opposite said first side marginal edge of said base portion to receive said opposite end of said elastic member. 4. The foldable device defined in claim 3 wherein said elastic member opposite end has at least a portion extending beyond said downwardly facing surface contact area for making contact with said resting surface to prevent said foldable device from sliding on said resting surface. 5. The foldable device defined in claim 1 wherein said elastic member is an elastomeric material. 6. The foldable device defined in claim 1 wherein said elastic member has memory retention characteristics. 7. The foldable device as defined in claim 1 further comprising a portable electronic device. 8. The foldable device as defined in claim 7 wherein said portable electronic device is a portable communication device. 9. The foldable device as defined in claim 7 wherein said portable electronic device is a portable hand-held electronic device. 10. The foldable device as defined in claim 7 wherein said portable electronic device is a compact, pocket sized electronic device. 11. A stabilizing mechanism in a hinged two part device having a first part arranged for pivotal movement with respect to a second part about a longitudinal folding axis passing through a hinge connecting said first and second parts for pivoting from a closed folded position through a pre-determined angular range to an open position, wherein said foldable device is configured in an infinite number of stable operative positions through the pre-determined angular range, comprising: at least one elastic member having one end fixedly attached to said first part and an opposite end fixedly attached to said second part, said elastic member having a bending section defined between said first and second ends and transverse to the longitudinal folding axis and formed between two spaced apart knuckles, such that said elastic member bends with a controlled variable displacement to provide an increasing contact surface as said first and second parts pivot relative to one another to keep the device from tipping over when the device is placed on a resting surface, said two spaced apart knuckles comprising a first knuckle located nearest said first part and a second knuckle located nearest said second part, said first knuckle having a dimension that is thinner than a dimension of said second knuckle such that the first knuckle deforms and bends at a faster rate than the second knuckle when the first part pivotably moves from said open position to said closed position. 12. The stabilizing mechanism defined in claim 11, wherein said first and second parts pivot relative to one another between 90° and 180°. 13. The stabilizing mechanism defined in claim 11, wherein said first part is a cover portion and said second part is a base portion, said base portion having a downwardly facing surface contact area and at least one lengthwise groove located in a spaced relation with a first side marginal edge and second side marginal edge opposite said first side marginal edge of said base portion to receive said opposite end of said elastic member. 14. The stabilizing mechanism defined in claim 13 wherein said elastic member opposite end has at least a portion extending beyond said downwardly facing surface contact area for making contact with said resting surface to prevent said foldable device from sliding on said resting surface. 15. The stabilizing mechanism defined in claim 11, wherein said elastic member is an elastomeric material. 16. The stabilizing mechanism defined in claim 11, wherein said elastic member has memory retention characteristics.
