Abstract

An accessory unit includes a front flap and a rear cover. The rear cover includes a recessed portion that defines a chamber and a lip that extends about an opening of the chamber. The chamber is configured to receive a consumer electronic device, and the lip is configured to hold the consumer electronic device therein. The rear cover can include a shell formed from glass fiber reinforced plastics and a lip formed from a thermoplastic. The front flap may include segments formed from panels with folding regions therebetween, which allow the front flap to fold. Further, an end region of the front flap hingedly couples the front flap to the rear cover, such that the front flap may be moved between open and closed configurations. Methods of manufacturing the accessory unit are also disclosed.

First claim

What is claimed is:

1. An accessory device for an electronic device, the accessory device comprising:
a shell comprising a bottom wall and sidewalls extending from the bottom wall to define a cavity having size and shape in accordance with the electronic device;
a lip formed continuously along the sidewalls to define a planar surface, the lip capable of retaining the electronic device within the cavity;
a rigid material embedded in and extending along the lip; and
a front flap connected to the shell, the front flap having a size and shape capable of folding onto the planar surface, the front flap comprising:
a first segment that carries a first magnetic element,
a second segment that carries a second magnetic element, and
a foldable region between the first segment and the second segment, wherein the first segment is foldable with respect to the second segment, and vice versa, based on the foldable region such that the first magnetic element magnetically couples with the second magnetic element and the first segment and the second segment form a three dimensional support structure for supporting the electronic device.

2. The accessory device of claim 1 , wherein the rigid material comprises fiber strands.

3. The accessory device of claim 1 , wherein the front flap extends directly from the lip.

4. The accessory device of claim 1 , wherein:
the shell comprises an opening for an operational component of the electronic device,
the shell comprises a first thickness, and
the shell comprises a second thickness around the opening, the second thickness being less than the first thickness.

5. The accessory device of claim 4 , further comprising:
a first layer covering an exterior of the shell;
a second layer covering an interior of the shell;
a rigid filler in the opening, the rigid filler covered by the first layer and the second layer.

6. The accessory device of claim 5 , wherein the second layer is indented such that the second layer is partially in the opening.

7. The accessory device of claim 1 , further comprising a third segment connected to i) the first segment by a first folding region, and ii) the second segment by a second folding region, the third segment foldable with respect to the first segment and the second segment based upon the foldable region and the second foldable region, respectively, wherein the third segment combines with the first segment and the second segment to form the three dimensional support structure.

8. An accessory device for an electronic device, the accessory device comprising:
a rear cover comprising a chamber having a size and shape in accordance with the electronic device;
a front flap configured to overlay the electronic device in a closed position; and
a hinge coupled with the front flap and the rear cover to allow the front flap to rotate with respect to the rear cover; and
a first magnetic element and a second magnetic element, wherein the first magnetic element and the second magnetic element are embedded in the hinge, and wherein in the closed position, the first magnetic element magnetically couples with the second magnetic element to maintain the front flap positioned over the rear cover.

9. The accessory device of claim 8 , wherein:
the rear cover comprises a shell, the shell comprising a rear wall and sidewalls that combine with the rear wall to define the chamber, and
the sidewalls comprise a lip.

10. The accessory device of claim 9 , wherein the sidewall comprises a first material, and wherein the lip comprises a second material different from the first material.

11. The accessory device of claim 9 , wherein the lip comprises a rigid material embedded in the lip.

12. The accessory device of claim 11 , wherein the rigid material comprises fiber strands.

13. The accessory device of claim 9 , first comprising a first layer and a second layer, wherein the first layer and the second layer combine to cover the rear cover, the front flap, and the hinge.

14. The accessory device of claim 13 , wherein in the shell comprises an opening in a location corresponding to a button of the electronic device, the opening having a rigid filler covered by the first layer and the second layer, wherein a force applied to the rigid filler causes a depression event of the button.

15. A method for assembling an accessory device suitable for use with an electronic device, the method comprising:
forming a shell comprising a bottom wall and sidewalls extending from the bottom wall to define cavity having a size and shape in accordance with the electronic device;
forming a lip continuously along the sidewalls to define a planar surface, the lip capable of retaining the electronic device; and
embedding a rigid material in the lip; and
connecting a front flap connected with the shell, the front flap having a size and shape capable of folding onto the planar surface, the front flap comprising:
a first segment carrying a first magnetic element,
a second segment carrying a second magnetic element, and
a third segment connected to i) the first segment by a first folding region, and ii) the second segment by a second folding region, wherein the first segment and the second segment are capable of folding along the first folding region and the second folding region, respectively, causing the first magnetic element to magnetically couple with the second magnetic element and forming a three dimensional support structure based upon the first segment, the second segment, and the third segment.

16. The method of claim 15 , wherein embedding the rigid material in the lip comprises embedding fiber strands in the lip.

17. The method of claim 15 , wherein forming the shell comprises a molding a first material, and wherein forming the lip continuously along the sidewalls comprises molding a second material different to the first material, the second material different from the first material.

18. The method of claim 15 , wherein forming the shell comprises:
forming an opening for an operational component of the electronic device,
forming the shell of a first thickness, and
forming the shell of a second thickness around the opening, the second thickness different from the first thickness.

19. The method of claim 18 , wherein the second thickness is less than the first thickness.

20. The method of claim 18 , further comprising:
covering an exterior of the shell with a first layer;
covering an interior of the shell with a second layer;
inserting a rigid filler in the opening, the rigid filler covered by the first layer and the second layer.
