Adjustable portable device holder

1. An adjustable portable device holder comprising:

an adjustable clamping element, wherein the adjustable clamping element is capable of being biased into an activated state and unbiased into a deactivated state to removably secure one of a plurality of different size portable devices to the adjustable portable device holder;

the adjustable clamping element comprising two side grips opposingly oriented to one another and each side grip has a device engaging surface that abuttingly engages a portable device in the activated state of the adjustable clamping element, wherein the two side grips linearly translate relative to one another upon transition between the activated and deactivated states of the adjustable clamping element;

the adjustable clamping element further comprising two rods, an expandable arm, a main body, and springs inserted one each over each rod and held in place by a screw affixed to an end of the respective rod; and

a rotatable mounting element attached to the adjustable clamping element by a rotary connection that permits 360 degree clockwise and counter-clockwise rotation of the adjustable clamping element relative to the rotatable mounting element, the rotatable mounting element comprising a pair of mounting arms spaced a distance apart from one another and converging toward one another, each extending at an angle away from a bottom surface of the rotatable mounting element and thereby forming a mounting slot between the pair of mounting arms,

wherein the rotary connection positions the mounting slot in various orientations relative to the adjustable clamping element across an entirety of the 360 degrees of rotation.

2. The adjustable portable device holder as recited in claim 1 , wherein a width of the mounting slot tapers away from the bottom surface of the rotatable mounting element and wherein the rotary connection is capable of releasably setting the mounting slot in two 180 degree spaced apart vertical orientations and two 180 degree spaced apart horizontal orientations for alternative engagement with vertically and horizontally oriented mounting surfaces.

3. The adjustable portable device holder as recited in claim 2 , wherein the mounting surface is an air conditioner vent blade in an automobile.

4. The adjustable portable device holder as recited in claim 1 , wherein each mounting arm tapers away from the bottom surface of the rotatable mounting element.

5. The adjustable portable device holder as recited in claim 1 , wherein the mounting arms comprise a gripping surface formed from gripping material.

6. The adjustable portable device holder as recited in claim 5 , wherein the gripping material is at least one material selected from the group consisting of: rubber, polymeric material, plastic, metal, alloy and composite material.

7. The adjustable portable device holder as recited in claim 5 , wherein the gripping surface is textured.

8. The adjustable portable device holder as recited in claim 1 , wherein the springs are loadable by an applied expansive force to bias the adjustable clamping element into the activated state.

9. The adjustable portable device holder as recited in claim 1 , wherein the adjustable clamping element comprises a gripping surface formed from gripping material.

10. The adjustable portable device holder as recited in claim 1 , wherein the device is a smartphone.

11. The adjustable portable device holder as recited in claim 1 , wherein the rotatable mounting element is attached with a screw to the adjustable clamping element.

12. The adjustable portable device holder as recited in claim 1 , wherein the rotatable mounting element is attached with a ratchet device to the adjustable clamping element.

13. The adjustable portable device holder as recited in claim 1 , wherein the rotatable mounting element is attached with a pin to the adjustable clamping element.

14. The adjustable portable device holder as recited in claim 1 , wherein the rotatable mounting element is friction fit to the adjustable clamping element.
