Patent ID: 7548761

Claim:
An electronic radiotelephone comprising a first and a second housing for housing electronic components of the radiotelephone and a biasing mechanism to aid a user to release the second housing from the first housing; the first housing having an element, with an operating surface, and a formation which co-operates with a complementary formation on the second housing for user releasable coupling of the first housing and the second housing; the element being movable between a first and a second position such that when the element is in the first position the formation and complementary formation co-operate to allow the first housing to be coupled to the second housing and when the element is in the second position to allow the second housing to be removed from the first housing by the user; wherein the biasing mechanism comprises a compression biased releasing mechanism and a compression biased urging mechanism, the compression biased releasing mechanism being arranged to resiliently compression bias the element into the first position to allow a user to actuate the element, via the operating surface, against the compression bias into the second position to release the co-operation of the formation and complementary formation thereby allowing the housings to be removed from one another, and wherein the compression biased urging mechanism is arranged to be in resilient compression to store energy when the formation and complementary formation are coupled and to automatically urge the first and second housings away from each other when the coupling of the formation and the complementary formation are released by releasing energy stored in the compression biased urging mechanism.
