Abstract

An inductive charging device for charging a mobile telephone within a public transport vehicle comprises a body section that includes an inductive charging device. A holder is provided for holding the mobile telephone in a fixed charging position relative to the inductive charging device. The holder includes a plurality of rigid arms that are fixed in position relative to the main body, and a plurality of biasing members movable between an extended position and a retracted position. The biasing members are arranged within the holder such that they are moved to the retracted position when the mobile telephone is inserted into the holder and in said retracted position apply an inwardly biasing force to the mobile telephone to hold it in the charging position.

Claims19

Dependent claims

An inductive charging device comprising:

a main body including an inductive charging unit;
and
a holder for holding a mobile device in a fixed charging position relative to the inductive charging unit;
wherein the holder comprises:
a lower clamping jaw fixed relative to the main body;
and
an upper clamping jaw slidably mounted to the main body above the lower clamping jaw such that the upper clamping jaw is able to freely slide vertically relative to the main body towards and away from the lower clamping jaw between an uppermost position and a lower clamping position;
wherein the lower clamping jaw comprises a cradle section for receiving and supporting a mobile device;
wherein the upper and lower clamping jaws are arranged such that:
when the upper clamping jaw is in the uppermost position, a mobile device may be inserted between the upper and lower clamping jaws;
and
when the upper clamping jaw is moved downwardly to the lower clamping position, a mobile device is clamped between the upper and lower clamping jaws;
and
wherein the upper clamping jaw is unbiased and freely slidable with no mechanism for fixing the upper clamping jaw in the lower clamping position.

An inductive charging device for charging a mobile device within a public transport vehicle, the inductive charging device comprising:

a main body including an inductive charging unit comprising a planar front surface;
and
a holder for holding a mobile device in a fixed charging position relative to the inductive charging unit;
wherein the holder comprises:
a plurality of rigid arms, fixed in position relative to the main body;
and
a plurality of biasing members movable between an extended position and a retracted position;
wherein the plurality of biasing members are arranged within the holder such that the plurality of biasing members are moved to the retracted position when a mobile device is inserted into the holder;
wherein, when in the retracted position, the plurality of biasing members apply an inwardly biasing force to the mobile device to hold the mobile device in the charging position;
and
wherein the plurality of biasing members includes a first pair of lateral biasing members arranged within the holder such that, in the retracted position, the first pair of lateral biasing members impart an inward biasing force in opposing lateral directions parallel to the planar front surface of the inductive charging unit.
