Battery-based wireless power device

Technical Field

The present disclosure relates generally to power supplies. More particularly, the present disclosure relates to a battery-based wireless power device for providing power at desks and workstations.

Background

As average workers and students use at least two devices (e.g., a phone and a tablet or notebook computer), there is an increasing demand for power to be supplied to the electronic devices of users. In today's workspace, the work environment becomes more active and mobile. Businesses offer fewer and fewer offices and support more and more open office environments with meeting and collaboration areas with movable mobile furniture.

Rotation of the bottom head portion 74 of the retaining member 34 causes adjustment of the upper and lower housings 12, 14 such that the battery-based wireless power device 100 is clamped onto the edge of the item of furniture 40 when the retaining member 34 is tightened. As each base head 74 rotates in the first rotational direction 76, the retaining member 34 moves longitudinally in the first clamping direction 78 to clamp an edge of an article of furniture therebetween. In other words, when the retaining member 34 is tightened and moved in the first clamping direction 78, the upper and lower housings 12, 14 are secured to the upper and lower surfaces 43, 44, respectively, of the item of furniture 40. As each base head 74 is rotated in the opposite second rotational direction 80, the retaining member 34 moves longitudinally in the second clamping direction 82 to unclamp. That is, as retaining member 34 is loosened and moved in second clamping direction 82, upper housing 12 and lower housing 14 are released from upper surface 43 and lower surface 44, respectively, of article of furniture 40. The first rotational direction 76 and the opposite second rotational direction 80 are shown here by way of example and are not limited to standard right-handed operation or clockwise operation. The first rotational direction 76 and the opposite second rotational direction 80 may optionally be reversed for left-handed operation or counterclockwise operation.

In one embodiment, the battery-based wireless power device 100 includes a rechargeable power source. The rechargeable power source is supported within the compartment 32 in the lower housing 14 and provides a source of electrical energy at the item of furniture 40, which eliminates the need for extension cords and power strips and the need to place the furniture near a wall outlet or other wired power source. In one embodiment, the rechargeable power source may be a rechargeable battery.
