One piece co-formed exterior hard shell case with an elastomeric liner for mobile electronic devices
View Patent ↗A one-piece co-formed exterior hard shell case with an elastomeric liner formed on the interior of the exterior hard shell for mobile electronic devices. This hard protective exterior shell allows the device maximum protection from impacts with sharp objects while the interior elastomeric portion that provides shock protection for the device from impacts. The exterior hard shell part is formed to fit the device closely with a small offset from the devices surface. The exterior hard shell raps around the edges of the device. To allow the shell to be able to be mounted on the device the corners of the hard shell are cut open. This allows each sidewall to flex away when a device is inserted and snap back once it is in place. The elastomeric material fills in the gaps created at the corners of the exterior hard shell to allow flex for mounting.
1. A protective case for a handheld mobile electronic device comprising:
a first portion creating an exterior hard shell, the first portion comprising a protective outer layer composed of a hardened plastic; and
a second portion comprising a flexible inner layer co-molded with and permanently affixed on an interior of the exterior hard shell first portion to form a co-molded, one-piece assembly;
wherein the co-molded, one-piece assembly defines a fitted cavity formed therein for mounting the handheld mobile electronic device to the protective case;
wherein the first portion includes a first cut away portion that is permanently filled with a portion of the flexible inner layer; and
wherein the portion of the flexible inner layer that fills in the first cut away portion creates a stretch-zone that is sufficiently flexible to enable the co-molded, one-piece assembly to deform and thereby accept insertion of the handheld mobile electronic device.
2. The protective case of claim 1 ;
wherein the portion of the flexible inner layer that fills the first cut away portion does not cover an exterior surface of the exterior hard shell.
3. The protective case of claim 1 ;
wherein the fitted cavity comprises one or more side surfaces.
4. The protective case of claim 3 ;
wherein an overhang extends from a top portion of one or more of the side surfaces.
5. The protective case of claim 4 ;
wherein the overhang is formed by the second portion.
6. The protective case of claim 3 ;
wherein the side surface is arranged to extend over a top surface of the handheld mobile electronic device when the device is fitted into the case.
7. The protective case of claim 4 ;
wherein the overhang is arranged to extend over a top surface of the handheld mobile electronic device when the device is fitted into the case.
8. The protective case of claim 1 ;
wherein the first portion forms at least two sides that define a corner and wherein the first cut away portion is located at the corner.
9. The protective case of claim 1 ;
wherein the first cutaway portion is one of a plurality of cutaway portions, each cut away portion being included in the first portion and permanently filled with a portion of the flexible inner layer;
wherein the first portion forms four sides defining four corners; and
wherein at least one of the cut away portions is located at each of the four corners.
10. The protective case of claim 1 ;
wherein the flexible inner layer comprises an elastomer.
11. The protective case of claim 1 ;
wherein the hard exterior shell comprises at least one of plastic, metal, a polycarbonate material, or a para-aramid material.
12. The protective case of claim 1 ;
wherein the flexible inner layer comprises at least one of rubber, silicon, plastic, or fabric.
