Expandable battery compartment for handheld electronic devices
View Patent ↗In a portable electronic device having a battery compartment and a removeable cover therefor, the battery compartment and cover are configured to accommodate batteries of at least two different sizes.
1. In a portable electronic device having a battery compartment and a removable cover therefor, the improvement comprising:
the battery compartment and cover being configured to accommodate batteries of at least two different sizes,
wherein the battery cover has an outer surface and side walls configured to encompass an installed battery, the battery compartment having flexible engagement apparatus extending inwardly therefrom, to engage recesses in the battery cover side walls, the recesses being provided at least two relative heights.
2. The improvement of claim 1 , wherein the flexible engagement apparatus is at a plurality of locations around the battery compartment.
3. The improvement of claim 1 , wherein the flexible engagement apparatus is a flange extending around the battery compartment.
4. The improvement of claim 1 , wherein the at least two sizes are discrete sizes.
5. The improvement of claim 1 , wherein the at least two sizes are various sizes along a continuum of sizes.
6. In a portable electronic device having a battery compartment and a removeable cover therefor, the improvement comprising:
the battery compartment and cover being configured to accommodate batteries of at least two different sizes,
wherein the cover has a generally rigid outer frame and a generally rigid center portion securable to the outer frame in either one of at least two positions, each the position corresponding to a different battery thickness.
7. The improvement of claim 6 , wherein the center portion has engagement elements to engage the outer frame, located away from a center plane of the center portion, such that rotation of the center portion about an axis in the plane of the center portion produces a smaller battery compartment in one such orientation than in the other such orientation.
8. The improvement of claim 6 , wherein the center portion has a shallow U-shape with an outer flange underlying an inwardly extending flange of the outer frame, such that rotation of the center portion about an axis in the plane of the center portion produces a smaller battery compartment in one such orientation than in the other such orientation.
9. In a portable electronic device having a battery compartment and a removable cover therefor, the improvement comprising:
the battery compartment and cover being configured to accommodate batteries of at least two different sizes wherein the cover has an outer surface and side walls configured to encompass an installed battery, the side walls having flexible engagement apparatus extending outwardly therefrom, to engage recesses in the battery compartment, the recesses being provided at least two relative heights.
10. The improvement of claim 9 , wherein the flexible engagement apparatus is at a plurality of locations around the side walls.
11. The improvement of claim 9 , wherein the flexible engagement apparatus is a flange extending around the side walls.
12. The improvement of claim 9 , wherein the flexible engagement apparatus is in the form of a plurality of elastomeric dimples.
13. The improvement of claim 9 , wherein the at least two sizes are discrete sizes.
14. The improvement of claim 9 , wherein the at least two sizes are various sizes along a continuum of sizes.
