Abstract

A protective case for a portable device having a touch screen is constructed from a back frame, a front frame and a stretchable cover. The back frame receives the device through an open front and the stretchable cover is stretched over the back frame and the device. A portion of the cover stretches over the back frame and device such that the device is securely held in the back frame. A front frame with a transparent screen protector that allows the touch screen of the portable device to be used while the device is fully enclosed in the case is removably coupled to the back frame with grasping protrusions or arms that connect to mounting portions on the back frame that extend through openings in the stretchable cover.

First claim

What is claimed is:

1. A case for a portable device having a touch screen, said case comprising:
a back frame that receives the portable device;
a stretchable cover that stretches over at least a portion of said back frame and said portable device when said portable device is in said back frame; and
a front frame having a transparent screen protector, wherein said front frame clamps over a portion of said stretchable cover and said back frame such that said portable device is held between said back frame and said front frame while said portable device is in said case, wherein said front frame further comprises an opening and said stretchable cover includes a button pad on said stretchable cover such that when said stretchable cover is stretched over said back frame, and said front frame is clamped over said stretchable cover and said back frame, said button pad fits in said opening.

2. The case of claim 1 wherein said front frame further comprises at least one grasping protrusion that mates with a corresponding mounting portion on said back frame.

3. The case of claim 2 wherein said stretchable cover includes a mounting opening and said mounting portion on said back frame extends through said mounting opening.

4. The case of claim 1 wherein said back frame includes raised shapes formed on the back of the back frame and extending through openings in the stretchable cover, wherein the raised shapes are octagons.

5. The case of claim 1 wherein said back frame includes a cavity on an interior surface of said back frame and a compressible pad mounted in said cavity, wherein when the portable device is inserted into the back frame, the compressible pad applies pressure to the back of the portable device.

6. The case of claim 1 wherein said back frame includes an opening that allows a user to remove said portable device from said back frame.

7. The case of claim 1 wherein said stretchable cover extends over said portable device when said portable device is mounted in said back frame and said stretchable cover is stretched over said back frame such that said portable device is held inside said back frame and stretchable cover.

8. The case of claim 1 wherein said back frame includes raised portions that extend through openings in a back of said stretchable cover that restrict movement of said stretchable cover with respect to said back frame.

9. The case of claim 1 wherein said back frame further comprises a screen formed in a microphone opening in said back frame.

10. The case of claim 1 wherein said front frame further comprises an opening for a speaker having a water resistant insert.

11. A case for a portable device having a touch screen, said case comprising:
a back frame shaped to receive the portable device such that a front of said portable device does not touch said back frame;
a stretchable cover that stretches over at least a portion of said back frame and said portable device when said portable device is mounted in said back frame; and
a front frame having a transparent screen protector, wherein said front frame clamps over a portion of said stretchable cover and said back frame such that said portable device is held between said back frame and said front frame, wherein said front frame further comprises an opening and said stretchable cover includes a button pad on said stretchable cover such that when said stretchable cover is stretched over said back frame, and said front frame is clamped over said stretchable cover and said back frame, said button pad fits in said opening.

12. The case of claim 11 wherein said front frame further comprises a raised portion and said transparent screen protector is mounted on said raised portion.

13. The case of claim 12 wherein said stretchable cover further comprises a front cavity shaped to receive said raised portion of said front frame to form a water resistant seal.

14. The case of claim 11 wherein said back frame further comprises a cavity on an interior surface of said back frame and a compressible pad mounted in said cavity, wherein when the portable device is inserted into the back frame, the compressible pad applies pressure to the back of the portable device.

15. The case of claim 11 wherein said front frame further comprises at least one grasping protrusion that mates with a corresponding mounting portion on said back frame.

16. The case of claim 11 wherein said stretchable cover further comprises bumper portions that extend past a front surface of said front frame when said front frame is coupled to said back frame.

17. The case of claim 11 wherein said stretchable cover further comprises a recessed sunken front portion that is shaped to receive said front frame when said front frame is mounted on said back frame.

18. A case for a portable device having a touch screen, said case comprising:
a back frame that receives the portable device, said back frame comprising:
at least one mounting portion;
a back frame opening for a control of the device;
a cavity on an interior surface of said back frame; and
an opening that allows a user to push said portable device from said back frame;

a stretchable cover, said stretchable cover comprising:
a portion that stretches over said back frame and said portable device when said portable device is in said back frame such that said portable device is held in said back frame;
a button pad on said stretchable cover; and
a mounting opening through which said mounting portion on said back frame extends when said stretchable cover is stretched over said back frame;

a front frame that clamps over said stretchable cover and said back frame, said front frame comprising:
a transparent screen protector that allows said touch screen of said portable device can be used while said portable device is in said case;
at least one grasping protrusion that couples to said at least one mounting portion on said back frame such that said portable device is held between said back frame and said front frame and a seal is created between said front frame and said stretchable cover; and
an opening in said front frame that receives said button pad on said stretchable cover when said device case is assembled such that a seal is created between said stretchable cover and said front frame around said opening in said front frame;

a compressible pad sized to fit in said cavity on said interior surface of said back frame.
