Abstract

A handheld lawn maintenance tool having a power head to which an adapter is attachable to allow both battery-powered and gasoline-powered working attachments to be attached thereto. The power head includes a power source, integrated first and second handles, a power generator, and a first attachment mechanism to which the adapter and/or working attachments are attachable.

First claim

What is claimed is:

1. A handheld lawn maintenance tool comprising a power head having a power source connected to a rear end of a housing, said housing including a first handle oriented along a longitudinal axis of said power head, a second handle extending from a fixed pivot point on a lower portion of said housing adjacent to a forward end of said housing, a control mechanism positioned adjacent to said first handle, a power generator located within said housing and operatively connected to said power source, and a first attachment mechanism configured to releasably attach alternately to a working attachment and to an adapter configured to connect to the working attachment, wherein said power generator is positioned between said first handle and said second handle, said power generator generates an output source of power, wherein the adapter is configured to alternately attach to a first working attachment and a second working attachment, wherein the first working attachment is battery-powered, wherein the second working attachment is engine-powered, and wherein the adapter comprises an extension member configured to conduct electrical power to the first working attachment and to provide movement to the second working attachment.

2. The handheld lawn maintenance tool of claim 1 , wherein said power source is removably attachable to said housing.

3. The handheld lawn maintenance tool of claim 2 , wherein said power source is a rechargeable battery.

4. The handheld maintenance tool of claim 1 , wherein said power source is a connecting mechanism for creating an electrical connection via a power outlet.

5. The handheld lawn maintenance tool of claim 1 , wherein said output source of power generated by said power generator is reciprocating movement or rotational movement.

6. The handheld lawn maintenance tool of claim 1 , wherein said second handle is rotatable in a fore/aft manner relative to said longitudinal axis.

7. The handheld lawn maintenance tool of claim 1 , wherein said first attachment mechanism includes a spring biased release button for disengaging said working attachment or said adapter from said power head.

8. The handheld lawn maintenance tool of claim 1 , wherein said first handle is in substantially linear alignment between said power source and said power generator.

9. A handheld lawn maintenance tool comprising:
a power head having a power source releasably attached thereto, said power head including a power generator electrically connected to said power source for generating output power, a first attachment mechanism operatively connected to said power generator, a trigger operatively connected to said power generator for selectively controlling said output power from said power generator, a housing, a first handle and a second handle integrally connected to said housing, said second handle extending from a fixed pivot point on a lower portion of said housing adjacent to a forward end of said housing, wherein said power generator is positioned between said first and second handles, and said second handle being rotatable in a fore/aft manner;
an adapter configured to be releasably attached to said first attachment mechanism of said power head, said adapter configured to receive said output power from said power generator; and
a working attachment configured to be releasably attached alternately to said adapter and to said first attachment mechanism of said power head, wherein said working attachment is configured to receive said output source of power alternately from said power generator directly and transferred via said adapter from said power generator to said working attachment, wherein the adapter is configured to alternately attach to a first working attachment and a second working attachment, wherein the first working attachment is battery-powered, wherein the second working attachment is engine-powered, and
wherein the adapter comprises a hollow extension member configured to provide movement to the second working attachment, and wherein the extension member comprises a conduit configured to conduct electrical power to the first working attachment.

10. The handheld lawn maintenance tool of claim 9 , wherein said power source is a rechargeable battery or a connecting mechanism for creating an electrical connection with a power outlet.

11. The handheld lawn maintenance tool of claim 9 , wherein said power generator produces reciprocating movement or rotational movement.

12. The handheld lawn maintenance tool of claim 9 , wherein said working attachment includes a tool.

13. The handheld lawn maintenance tool of claim 12 , wherein said tool includes at least one of a hedge trimmer, an edger, a tiller, a chainsaw, a polesaw, or a blower.

14. The handheld lawn maintenance tool of claim 13 , wherein said output source of power from said power generator is reciprocating movement or rotational movement that is transferred to said working attachment via said adapter.

15. The handheld lawn maintenance tool of claim 9 further comprising a boom having a first end releasably attachable to said adapter and an opposing second end attachable to said working attachment, said output source of power being transferrable from said adapter to said working tool via said boom.

16. The handheld lawn maintenance tool of claim 9 , wherein said first handle is oriented along a longitudinal axis of said power head.

17. The handheld lawn maintenance tool of claim 9 , wherein said first attachment mechanism includes a spring biased release button for disengaging said adapter from said power head.

18. A handheld lawn maintenance tool comprising:
a power head including a housing, a power source releasably attached to a rear end of said housing, a power generator positioned within said housing and electrically connected to said power source for generating an output, said housing including a first handle positioned between said power source and said power generator, a second handle extending from a fixed pivot point on a lower portion of said housing adjacent to a forward end of said housing, a first attachment mechanism positioned longitudinally forward of said second handle, a trigger positioned adjacent to said first handle and operatively connected to said power generator for selectively controlling said output of said power generator, wherein said power generator is positioned between said first and second handles, and said second handle is rotatable in a fore/aft manner;
a working attachment configured to be releasably attached alternately to said first attachment mechanism of said power head and to an adapter configured to be releasably attached to said first attachment mechanism of said power head, wherein said output of said power generator is transferred to said working attachment, and said working attachment being formed as a string trimmer, a blower, an edger, a tiller, a chainsaw, or a polesaw, wherein the adapter is configured to alternately attach to a first working attachment and a second working attachment, wherein the first working attachment is battery-powered, wherein the second working attachment is engine-powered, and wherein the adapter comprises an extension member configured to provide electrical power to the first working attachment and to provide movement to the second working attachment.
