Abstract

A battery pack charger system may include a first charger configured to charge a first battery pack, a second charger configured to charge a second battery pack, a support arranged between the first charger and the second charger, and a power cord configured to deliver power. The first charger may be attached on a first side of the support and the second charger may be attached on a second side of the support that is opposite the first side of the support. The first charger and the second charger may be arranged directly opposite of each other. The power cord may be connected to one of the first charger or the second charger.

First claim

What is claimed is:

1. A battery pack charger system, comprising:
a first charger configured to charge a first battery pack;
a second charger configured to charge a second battery pack;
a support member arranged between the first charger and the second charger, the support member including a platform portion configured to support the first charger and the second charger and a projecting portion extending away from the platform portion and configured to support the first battery pack and the second battery pack, the first charger attached on a first side of the support member and the second charger attached on a second side of the support member that is opposite the first side of the support member and the first side of the support member is a different side of the support member from the second side of the support member; and
a power cord configured to deliver power, the power cord being connected to one of the first charger or the second charger.

2. The battery pack charger system of claim 1 , wherein the first charger includes a first connecting structure to engage with the first battery pack and the second charger includes a second connecting structure to engage with the second battery pack, the second connecting structure being the same as the first connecting structure.

3. The battery pack charger system of claim 2 , wherein:
the first connecting structure includes guide rails configured to engage with corresponding guide rails of a slide-on style battery pack, and
the second connecting structure includes guide rails configured to engage with corresponding guide rails of a slide-on style battery pack.

4. The battery pack charger system of claim 1 , wherein the platform portion comprises:
a first pair of pedestals on the first side to be connected to a pair of screw bosses formed on the first charger; and
a second pair of pedestals on the second side to be connected to a pair of screw bosses formed on the second charger.

5. The battery pack charger system of claim 1 , wherein the platform portion includes a curved portion.

6. The battery pack charger system of claim 5 , wherein each of the first charger and the second charger includes a curved portion to correspondingly engage with the curved portion of the platform portion.

7. The battery pack charger system of claim 1 , further comprising a power brick configured to be attached to one of the first charger or the second charger.

8. The battery pack charger system of claim 7 , wherein the power brick includes guide rails to corresponding engage with guide rails of one of the first battery charger or the second battery charger when one of the first battery pack or the second battery pack is removed from the respective first charger or the second charger.

9. The battery pack charger system of claim 7 , wherein the power brick includes a recess to permit an electrical cord from the power brick to be wrapped within the recess.

10. The battery pack charger system of claim 1 , wherein the first charger and the second charger are arranged directly opposite of each other such that terminal slots on the first battery pack that engage terminal blades on the first charger face terminal slots on the second battery pack that engage terminal blades on the second charger.
