Mobile phone body with lateral indents for attachable accessory
A mobile phone includes a phone body including spaced lateral perimeter walls. At least one indentation is provided in each of the said spaced lateral walls, the indentations forming a detent or cavity to provide an overhang portion suitable for being selectively gripped or released by correspondingly mating jaws or hooks on an accessory attachable to the mobile phone.
1. A latching system for removably attaching an accessory to a mobile phone comprising a phone body including spaced lateral walls; at least one indentation in each of said spaced phone lateral walls, said indentations forming an overhang portion suitable for being selectively gripped or released by correspondingly mating jaws or hooks on an accessory attachable to the mobile phone, said accessory having spaced lateral walls substantially coextensive with said mobile phone body spaced lateral walls and comprising a lever at each accessory lateral wall; a jaw or hook on each of said levers arranged to normally be received within an associated indentation when said accessory is mated to said mobile phone; and a user button on said accessory to actuate an associate lever to withdraw said jaw or hook from an associated indentation when pressed inwardly towards said accessory, said user buttons associated with said levers at each accessory lateral wall being positioned on opposing sides of said accessory requiring substantially equal and opposite forces to be applied to said buttons to provide an ergonomic release mechanism for releasing said accessory from said mobile phone.
2. A system as defined in claim 1 , wherein said mobile phone is provided with two spaced indentations arranged along each mobile phone lateral wall, said latching system comprises two levers at each accessory lateral wall; a jaw or hook on each of said levers arranged to normally be received within associated indentations when said accessory is mated to said mobile phone; a user button arranged on said accessory to actuate both levers at each accessory lateral wall to withdraw said jaws or hooks from associated indentations when pressed inwardly towards said accessory, said user buttons associated with said levers being positioned on opposing sides of said accessory, requiring substantially equal and opposite forces to be applied to said buttons to provide an ergonomic release mechanism for releasing said accessory from said mobile phone.
3. A system as defined in claim 1 , further comprising biasing means for normally urging said levers to latching positions to cause said jaws or hooks to be received and remain within said indentations until user applied forces are applied to said buttons.
4. A system as defined in claim 3 , wherein said biasing means comprise compression springs.
5. A system as defined in claim 1 , wherein said levers are class 1 levers.
