Abstract

A tool system for use with an accessory tool including a mounting end, comprises an oscillating power tool and a handheld tool assembly. The oscillating power tool includes a first tool holder configured to connect to the mounting end of the accessory tool. The handheld tool assembly includes a second tool holder configured to connect to the mounting end of the accessory tool.

First claim

What is claimed is:

1. A tool system, comprising:
an accessory tool including a working end and a mounting end extending from the working end, the mounting end defining a plurality of openings arranged in a desired configuration;
an oscillating power tool including a first tool holder having a first mounting structure including a first plurality of protrusions arranged in the desired configuration and configured to be received by the plurality of openings to connect the mounting end of the accessory tool to the oscillating power tool; and
a handheld tool assembly including a second tool holder having a second mounting structure including a second plurality of protrusions arranged in the desired configuration and configured to be received by the plurality of openings to connect the mounting end of the accessory tool to the handheld tool assembly.

2. The system of claim 1 , wherein the handheld tool assembly comprises:
a tool shaft; and
a handle extending from a first end of the tool shaft,
wherein at least a portion of the second tool holder extends from a second end of the tool shaft opposite of the first end,
wherein movement of the accessory tool relative to the handle is prevented when the second tool holder is connected to the mounting end.

3. The system of claim 2 , wherein the second tool holder comprises:
a threaded bore located in a center of the second plurality of protrusions; and
a clamping member including a threaded pin configured to be threadingly connected to the threaded bore,
wherein the second tool holder is connected to the mounting end of the accessory tool when the second plurality of protrusions are received by the plurality of openings and the threaded pin is threadingly connected to the threaded bore.

4. The system of claim 3 , wherein the clamping member further comprises:
a knob extending from an opposite side of the clamping member from the threaded pin.

5. The system of claim 2 , wherein the second tool holder comprises:
a clamping member pivotably connected to the tool shaft and configured for movement to a clamped position and an unclamped position, the clamping member including a clamping head configured (i) to clamp the mounting end against the second mounting structure in response to the clamping member being in the clamped position, and (ii) to unclamp the mounting end to enable removal of the accessory tool from the second mounting structure in response to the clamping member being in the unclamped position.

6. The system of claim 5 , wherein the second tool holder further comprises:
an actuation mechanism including a button movable to a locked position and an unlocked position, and a biasing member configured to bias the button toward the locked position,
wherein the actuation mechanism prevents movement of the clamping member from the clamped position to the unclamped position when button is in the locked position, and
wherein the actuation mechanism enables movement of the clamping member from the clamped position to the unclamped position when the button is in the unlocked position.

7. The system of claim 5 , further comprising:
a biasing member configured to bias the clamping member in the clamped position.

8. The system of claim 7 , wherein:
the clamping member is configured to pivot about a pin, and
the pin is located between the biasing member and the second mounting structure.

9. The system of claim 7 , wherein:
the clamping member is configured to pivot about a pin, and
the biasing member is located between the pin and the second mounting structure.

10. The system of claim 5 , further comprising:
a locking pin located in a slot defined by the tool shaft and slidable to a locked position and an unlocked position; and
a locking hook extending from the clamping member, the locking hook configured to engage the locking pin in response to the clamping member being in the clamped position and the locking pin in the locked position to prevent movement of the clamping member from the clamped position to the unclamped position.

11. The system of claim 2 , further comprising:
a pivot mechanism located between the handle and the second tool holder and configured to enable movement of the second tool holder relative to the handle.
