Abstract

An extendable hedge trimmer includes a housing having a handle end and a tool end. The handle end includes a battery and an electrical connector. The tool end includes a hedge trimming implement, a motor, and an electrical connector. The electrical connector of the tool end is electrically connected with the motor. Wiring is included within the handle end for electrically connecting the battery and the electrical connector of the handle end. The trimmer also includes a pole which is releasably connectable between the tool end and the handle end. The pole is configured for electrically connecting the handle end with the tool end. The trimmer also includes a latch mechanism for releasably attaching the pole between tool end and handle end. The trimmer also includes an input for receiving AC line power via a power cord, the trimmer configured for being power by AC line power and/or battery power.

First claim

The invention claimed is:

1. A power tool, comprising:
a handle end having a recess formed therein and a first electrical connector disposed within the recess;
a battery removably attached to the handle end, wherein the battery is operatively connected to the first electrical connector within the recess when the battery is attached to the handle end; and
a tool end removably attached to the handle end, the tool end having a motor extending outwardly and located within a motor housing and a second electrical connector located at an end of the motor housing, the second electrical connector of the tool end being operatively connected to the motor, the second electrical connector of the tool end further being operatively connected to the first electrical connector of the handle end due to the motor and the end of the motor housing being inserted into the recess of the handle end to provide the removable attachment of the tool end to the handle end;
wherein the tool end is formed as one of a saw implement, a hedge trimming implement, a chainsaw implement, or a gardening attachment.

2. The power tool of claim 1 , wherein the tool end formed as a gardening attachment is a blower.

3. A power tool, comprising:
a handle end having a recess formed therein and a first electrical connector disposed within the recess;
a battery removably attached to the handle end, wherein the battery is operatively connected to the first electrical connector within the recess when the battery is attached to the handle end;
a tool end having a motor located within a motor housing, the motor housing projecting longitudinally outward and a second electrical connector located at an end of the motor housing, the second electrical connector of the tool end being electrically connected to the motor; and
a pole removably attached to the handle end and to the tool end, the pole having a first end and a second end electrically connected to the first end, wherein the first end of the pole is releasably attached to the handle end and the second end of the pole is releasably attached to the tool end, wherein the second end of the pole receives the motor and the end of the motor housing of the tool end, and the first electrical connector of the handle end is electrically connected to the second electrical connector of the tool end due to the pole being attached to both the handle end and the tool end to provide the removable attachment of the pole to the handle end and to the tool end;
wherein the tool end is formed as one of a saw implement, a hedge trimming implement, a chainsaw implement, or a gardening attachment.

4. The power tool of claim 3 , wherein said pole is a telescoping pole.

5. A power tool, comprising:
a housing including a handle end and a tool end, the handle end and the tool end configured for being removably and directly connected together, the handle end having a battery, a recess formed into the handle end, and a first electrical connector located within the recess wherein the battery is electrically connected to the first electrical connector, the tool end having a motor located within a motor housing, the motor housing extending outwardly and a second electrical connector located at an end of the motor housing, the second electrical connector of the tool end being electrically connected with the motor, wherein the motor and the end of the motor housing are receivable into the recess of the handle end for operatively connecting the first and second electrical connectors to one another when the handle end and the tool end are directly connected together;
a pole being releasably connected between said tool end and said handle end, one end of the pole being electrically connected to an opposing end of the pole, wherein the handle end and the tool end are electrically connected to each other due to one of the ends of the pole being attached to the handle end and the other of the ends of the pole receiving the motor and the end of the motor housing to provide the releasable connection of the pole between said tool end and said handle end; and
a pair of latch mechanisms, the latch mechanisms releasably attaching said one end of the pole to the tool end and said opposing end of the pole to the handle end;
wherein the tool end is formed as one of a saw implement, a hedge trimming implement, a chainsaw implement, or a gardening attachment.

6. The power tool of claim 5 , wherein the tool end formed as a gardening attachment is a blower.

7. The power tool of claim 5 , wherein said pole is a telescoping pole.
