Filed:

Dec 1, 2000

Appl. No.:

09/727664

Inventors:

Peter W. Neumann - Chicago IL

Assignee:

S-B Power Tool Company - Chicago IL

International Classification:

H02J 700

US Classification:

307150, 307 80, 320114, 439188

Abstract:

A power supply for a power tool which is adapted to be powered by a battery source and an AC voltage source includes a battery module constructed and adapted to be removably coupled to the power tool. The battery module includes a battery pack for supplying power to the power tool. A power converter module supplies current for charging the battery pack and for operating the power tool. A power plug extends from the power converter module and is adapted to be connected to the battery module. The power plug has a first output for supplying the tool operating current to the power tool and a second output for supplying the battery charging current to the battery pack when the plug is connected to the battery module. A switching device is provided in the battery module for electrically disconnecting the battery pack from the power tool responsive to the plug being connected to the battery module.

Appl. No.:

10/226840

Inventors:

Barry Howard Jacobs - Forest Park IL
Peter Neumann - Chicago IL

Assignee:

S-B Power Tool Corporation - Broadview IL

International Classification:

H02J 700

US Classification:

320113, 320107

Abstract:

A splitting adapter for a battery charger having a power cord for connection to an electrical source, the charger having a single charging receptacle for receiving a connector extension of a battery pack of the type used with cordless power tools, said adapter including a housing having a housing connector extension with a sufficiently similar structural and electrical configuration as the connector extension of the battery pack so that the housing can be electrically connected to the battery charger when said housing connector extension is inserted into the charging receptacle. The splitting adapter also includes at least two charging receptacles, each of which is configured to receive a battery pack connector extension, where the charging receptacles are spaced from one another a sufficient distance that the battery packs will not interfere with one another when inserted into the adapter.

Assignee:

S-B Power Tool Corporation - Chicago IL

International Classification:

G05F 1652

US Classification:

323222, 323224, 323284

Abstract:

A DCâDC voltage converter that is capable of increasing as well as decreasing the voltage of a battery pack for application to a power tool or other load. The converter thereby enables different voltage batteries to be used with power tools that have motors that operate at different voltages. The voltage conversion is accomplished by using a relatively high speed switching circuit wherein the duty cycle of the switching circuitry varies the output voltage. An alternative embodiment utilizes feedback control circuitry to automatically adjust the duty cycle so that the speed of the motor, which is a function of the voltage applied to it, would be held generally constant.

US Classification:

403326, 4031092, 15145, 16422

Abstract:

A push-lock handle assembly includes segments that are interconnected by axial movement using snap-in D-shaped tabs and recesses. Slits and grooves allow the tabs to deflect slightly inwardly during insertion. In another form there is a grip section, at least one pole section, and one accessory attachment section. Simple axial movement snap locks the parts together.
