Protective case for mobile device with reinforcing support member
View Patent ↗A protective case for a mobile device having a co-molded multi-layered construction having a first layer that generally forms the external back face surface of the case. A second layer generally forms the perimeter bumper of the case. The first layer is comprised of material that has a hardness and/or rigidity that is greater than the second layer. The layers are configured to interact with one another so that they are capable of distributing impact forces to mitigate damage to the mobile device. One or more reinforcing support members in the form of a beam or rod are provided and extend internally and longitudinally near the sides of the case and preferably near the long sides of a rectangular shaped case. The reinforcing support members are formed of even harder or more rigid materials, such as metal alloy or cured fiber reinforced composite rods or beams, relative to the first and second layer and are capable of providing additional support and rigidity to the mobile device to stop or mitigate unintentional or undesired bending of the mobile device.
1. A rectangular shaped protective case for a mobile electronic device configured to be user removable from said mobile electronic device, wherein said mobile device includes a height that is defined as the distance between a front face and a back face of the mobile device, a perimeter defined by top, bottom, right, and left sides residing between the front and back faces, and corners defined at the intersecting regions of the sides, said protective case comprising:
a bottom shell portion made of a first material that is dimensioned to cover at least a portion of the back face of the mobile device;
an upper portion that is co-molded to the bottom shell that is made of a second material that is less rigid or hard than the first material, wherein the upper portion is configured to cover at least a portion of the perimeter region of the front face of the mobile electronic device; and
one or more longitudinally extending reinforcing support members being housed within the bottom shell portion and made of a third material that is more rigid than either the first or second material, wherein said reinforcing support members extend lengthwise generally parallel to the long sides of the protective case.
2. The protective case of claim 1 , wherein one or more of said one or more reinforcing support members is molded within said bottom shell portion.
3. The protective case of claim 1 , wherein one or more of said one or more reinforcing support members is constructed of metal.
4. The protective case of claim 1 , wherein one or more of said one or more reinforcing support members is formed of cured fiber reinforced plastic construct that is molded within said bottom shell portion.
5. The protective case of claim 1 , wherein one or more of said one or more reinforcing support members is in a form of a longitudinally extending beam, which includes a rectangular cross-section having a width and height dimension of 3 mm or less.
6. The protective case of claim 1 , wherein one or more of said one or more reinforcing support members is in a form of a longitudinally extending beam, which has a circular cross-section having a diameter of 1.5 mm or less.
7. The protective case of claim 1 , wherein said bottom shell fixedly houses a first reinforcing support member on first side of the case and a second reinforcing support member on an second side of the case that is opposite said first side.
8. The protective case of claim 1 , wherein said bottom shell fixedly houses a first group of multiple reinforcing support members on a first side of the case and a second group of multiple reinforcing support members on a second side of the case that is opposite said first side.
9. The protective case of claim 8 , wherein the reinforcing support members in the first group have different cross-section dimensions and differing lengths.
10. The protective case of claim 9 , wherein the reinforcing support members in the second group have different cross-section dimension and differing lengths.
11. The protective case of claim 7 , wherein the first reinforcing support member is identical to the second reinforcing support member.
12. The protective case of claim 7 , wherein one or both of the first or second reinforcing support members has greater dimensions in a region configured to be positioned near control buttons on the mobile electronic device.
13. The protective case of claim 7 , wherein one or both of the first or second reinforcing support members is constructed to be more rigid in a first region than adjacent second region.
14. The protective case of claim 7 , wherein one or both of the first or second reinforcing support members is constructed to be thinner in a first region than adjacent second region.
15. The protective case of claim 7 , wherein one or both of the first and second reinforcing support members is constructed to have a cross-section having an area in a first region that is greater than the area of the cross-section taken at a second region that is separated a first longitudinally extending distance away from said first region.
