Universal folio case with adjustable fit for a mobile electronic device
View Patent ↗An adjustable case for a mobile electronic device. The case has a bottom including a main chassis, a fixed holding member fixedly connected with the main chassis, a sliding holding member slidedly connected to the main chassis to slide back and forth, and a tension mechanism biasing the sliding holding member towards the fixed holding member so that the fixed holding member and the sliding holding member squeeze the mobile electronic device when fitted in the case. A plurality of friction members is fixed to a mobile-device-facing surface of the case bottom so that the friction members contact a bottom of the mobile electronic device when the mobile electronic device is fitted in the case. A plurality of raised corner sidewalls is also provided, each sidewall arranged at a corner of the main chassis to extend in a mobile-device-facing direction from the mobile-device-facing surface of the bottom of the case.
1. An adjustable case for a mobile electronic device, said adjustable case comprising:
a bottom comprising
a main chassis;
a fixed holding member fixedly connected with the main chassis;
a sliding holding member slidedly connected to the main chassis to slide back and forth;
a tension mechanism, which biases the sliding holding member towards the fixed holding member so that the fixed holding member and the sliding holding member are configured to squeeze the mobile electronic device when the mobile electronic device is fitted in the case;
a plurality of friction members fixed to a mobile-device-facing surface of the bottom of the case so that the friction members contact a bottom of the mobile electronic device when the mobile electronic device is fitted in the case; and
a plurality of raised corner sidewalls, each being arranged at a corner of the main chassis and extending in a mobile-device-facing direction from the mobile-device-facing surface of the bottom of the case.
2. The adjustable case according to claim 1 ;
wherein the friction members comprise at least one material selected from the group consisting foam materials, elastomeric materials, styrene-butadiene rubber, ethylene-vinyl acetate, and neoprene.
3. The adjustable case according to claim 1 ;
wherein the tension mechanism comprises an elastic member.
4. The adjustable case according to claim 1 ;
wherein the tension mechanism comprises a spring member.
5. The adjustable case according to claim 1 ;
wherein the main chassis comprises at least one rigid or semi-rigid material selected from the group consisting of plastic materials, rigid rubber materials, engineering thermoplastic materials, composite materials, polycarbonate materials, and para-aramid materials.
6. The adjustable case according to claim 1 ;
wherein the raised corner sidewalls each comprises at least one rigid or semi-rigid material selected from the group consisting of plastic materials, rigid rubber materials, engineering thermoplastic materials, composite materials, polycarbonate materials, and para-aramid materials.
7. The adjustable case according to claim 1 ;
wherein the raised corner sidewalls are integral with the main chassis.
8. The adjustable case according to claim 1 ;
wherein the raised corner sidewalls are raised at least 3.00 mm from the mobile-device-facing surface of the bottom of the case.
9. The adjustable case according to claim 8 ;
wherein the raised corner sidewalls are raised from 5.00-20.00 mm from the mobile-device-facing surface of the bottom of the case.
10. The adjustable case according to claims 9 ;
wherein the raised corner sidewalls are raised from 8.00-15.00 mm from the mobile-device-facing surface of the bottom of the case.
11. The adjustable case according to claim 1 ;
wherein the raised corner sidewalls are solid without any holes.
12. The adjustable case according to claim 1 , further comprising:
a top which is hingedly connected to the bottom of the case to switch between:
a state where the top is disposed over the mobile-device-facing surface of the bottom of the case; and
a state where the top is swung away from and exposes the mobile-device-facing surface of the bottom of the case.
13. The adjustable case according to one claim 12 ;
wherein the top comprises a groove; and
wherein the case is switchable into a standing state in which the bottom of the case is arranged in the groove of the top.
14. The adjustable case according to claim 1 ;
wherein the mobile electronic device includes:
a screen on a face of the mobile electronic device; and
two pairs of opposite sides that form a rectangular perimeter around the face; and
wherein the fixed holding member and the sliding holding member are configured to engage with one of the pairs of opposite sides of the perimeter of the mobile electronic device when the mobile electronic device is fitted in the case.
15. The adjustable case according to claim 14 ;
wherein the two pairs of opposite sides of the mobile electronic device comprise:
a short pair of opposite sides; and
a long pair of opposite sides that are longer than the short pair of opposite sides; and
wherein the fixed holding member and the sliding holding member are configured to engage with the long pair of opposite sides of the perimeter of the mobile electronic device when the mobile electronic device is fitted in the case.
16. The adjustable case according to claim 1 ;
wherein the adjustable case is configured to be switched to a standing state where the adjustable case fully supports itself on a resting surface and maintains a surface of the main chassis, extending between the fixed holding member and the sliding holding member, at an inclined angle with respect to the resting surface; and
wherein the sliding holding member is arranged in the bottom of the case so that the sliding holding member is located below the fixed holding member when the case is in the standing state.
