## Abstract

A charger cradle for recharging a rechargeable lighting device is described. The cradle may include two prongs that flex outwards to allow a lighting device to be inserted into the cradle. After the lighting device is fully inserted, the prongs resume a normal position to exert an inward force on the lighting device to secure it in place. The cradle may also include two moveable cradle arms, in lieu of two prongs, to allow a spring mechanism within the device to motivate the moveable cradle arms to grasp a lighting device when the lighting device is inserted into the rechargeable lighting device.

## Claims

### Claim 1

A charger cradle for recharging a lighting device, comprising:
a base having two prongs for engaging the lighting device as it is inserted into the cradle;
a housing attached to the base; and
a printed circuit board that is positioned between the base and housing and that includes a recharging circuit;
wherein the prongs bend outward while the lighting device is inserted into the cradle, and then exert an inward force on the lighting device when the lighting device is inserted into the cradle.

### Claim 2 (depends on 1)

The charger cradle of claim 1, further comprising an LED to indicate when charging occurs.

### Claim 3 (depends on 2)

The charger cradle of claim 2, further comprising a light pipe to transmit light from the LED to a surface of the cradle.

### Claim 4 (depends on 1)

The charger cradle of claim 1, wherein the housing includes a cylindrical portion and a flared portion.
