Abstract

Systems, methods, and articles to provide a charging cradle or base station that includes one or more movable electrical contacts. Generally, each of the movable contacts protrudes through an opening in a surface of the cradle only when a cordless electrical device is positioned on or within the cradle. When the cordless electrical device is not positioned on or within the cradle, the one or more movable contacts are retracted inside the body of the cradle such that the movable contacts cannot be bumped or hit by the reader during insertion of the reader into the cradle and during removal of the reader from cradle. Systems, methods, and articles to provide a charging cradle or base station with selectively removable electrical contacts are also disclosed.

Claims

1. A cradle for an electrical device, the electrical device includes an external surface having an electrical contact thereon, the electrical contact electrically coupled to at least one electrical component of the electrical device, the cradle comprising:

a body that includes;

a device receiver portion that receives or supports at least a portion of the electrical device, the device receiver portion includes a contact surface positioned adjacent the external surface of the electrical device when the at least a portion of the electrical device is received or supported by the device receiver portion, the contact surface includes a contact aperture therein;

an electrical contact; and

a contact actuator physically coupled to the electrical contact, the contact actuator moves the electrical contact between a retracted position wherein the electrical contact of the cradle is positioned below the contact surface of the device receiver portion, and a protruded position wherein the electrical contact at least partially extends above the contact surface through the contact aperture,

wherein the contact surface of the device receiver portion includes a switch aperture, and the contact actuator comprises a beam and a switch, the beam pivotable about a pivot point, a first end of the beam physically coupled to the electrical contact and a second end of the beam physically coupled to the switch, the switch at least partially protrudes through the switch aperture of the contact surface of the device receiver portion when the at least a portion of the electrical device is separated from the device receiver portion and, when the at least a portion of the electrical device is received or supported by the device receiver portion, the switch contacts at least a portion of the electrical device and causes the beam to pivot until the electrical contact is in the protruded position.

2. The cradle of claim 1 wherein the contact actuator includes an elastic member that biases the electrical contact in the retracted position when the at least a portion of the electrical device is separated from the device receiver portion.

3. The cradle of claim 2 wherein the elastic member comprises a coil spring.

4. The cradle of claim 1 wherein the contact actuator includes at least one magnet that biases the electrical contact in at least one of the retracted position or the protruded position.

5. The cradle of claim 4 wherein the magnet causes at least one of an attraction force or a repulsion force with a component of the electrical device when the at least a portion of the electrical device is received or supported by the device receiver portion.

6. The cradle of claim 1, further comprising:

a power source electrically coupleable to the electrical contact of the cradle.

7. The cradle of claim 1 wherein the body, the electrical contact and the contact actuator are selectively removable from a base portion of the cradle which houses one or more electrical components.

8. The cradle of claim 7 wherein the electrical contact is electrically coupleable to the one or more electrical components housed in the base portion of the cradle via at least one mechanical interlock.

9. The cradle of claim 1, wherein the cradle is a cradle for a machine-readable symbol reader.
