Abstract

An oscillating interface for an oscillating too includes a post, a pin which extends through the post, a flange slidably positioned on the post between the pin and a distal end of the post. The flange includes a drive side and a mounting side. The drive side includes a drive structure configured to interlock with a drive structure of an accessory tool. The mounting side is arranged facing the pin and defines at least one notch configured to receive the pin. A clamping member is configured to be threaded onto the post and to clamp the flange against the pin with the pin received in the notch.

Claims

1. An oscillating interface for an oscillating tool, comprising:

a post configured to extend from an oscillating drive member of an oscillating power tool, the post including a flange receiving portion and a threaded portion, the flange portion extending from the oscillating drive member, the threaded portion extending from the flange receiving portion;

a pin which extends through the post and protrudes from at least one side of the post;

a flange slidably positioned on the flange receiving portion of the post between the pin and the threaded portion of the post, the flange including a drive side and a mounting side, the drive side including a drive structure configured to interlock with a drive structure of an accessory tool, the mounting side being arranged facing the pin and defining at least one notch configured to receive the pin; and

a clamping member configured to be threaded onto the threaded portion of the post and to clamp the flange against the pin with the pin received in the notch.

2. The oscillating interface of claim 1, wherein the flange includes a plurality of notches which are arranged radially on the mounting side of the flange, each of the notches in the plurality being configured to receive the pin.

3. The oscillating interface of claim 1, wherein the clamping member is a nut.

4. The oscillating interface of claim 3, wherein the clamping member is a captive nut.

5. The oscillating interface of claim 1, further comprising:

a biasing member configured to bias the flange toward the clamping member.

6. The oscillating interface of claim 1, wherein the flange includes a first notch and a second notch which are arranged radially on the mounting side of the flange, the first notch having a first depth, the second notch having a second depth, the second depth being greater than the first depth.

7. The oscillating interface of claim 1, wherein the flange includes a counterweight for counterbalancing an accessory tool attached to the oscillating interface.

8. The oscillating interface of claim 1, wherein the flange includes a slot and a plurality of notches which are arranged parallel to each other and perpendicular to a longitudinal dimension of the slot, and

wherein the flange includes an accessory tool mounting portion which is configured to retain an accessory tool on the flange.

9. An oscillating power tool comprising:

a portable, handheld housing;

a motor enclosed in the housing;

an oscillating drive member configured to be oscillating by the motor;

a post extending from the oscillating drive member, the post including a flange receiving portion and a threaded portion, the flange portion extending from the oscillating drive member, the threaded portion extending from the flange receiving portion;

a pin which extends through the post and protrudes from at least one side of the post;

a flange slidably positioned on the flange receiving portion of the post between the pin and the threaded portion of the post, the flange including a drive side and a mounting side, the drive side including a drive structure configured to interlock with a drive structure of an accessory tool, the mounting side being arranged facing the pin and defining at least one notch configured to receive the pin; and

a clamping member configured to be threaded onto the threaded portion of the post and to clamp the flange against the pin with the pin received in the notch.

10. The oscillating power tool of claim 9, wherein the flange includes a plurality of notches which are arranged radially on the mounting side of the flange, each of the notches in the plurality being configured to receive the pin.

11. The oscillating power tool of claim 9, wherein the clamping member is a nut.

12. The oscillating power tool of claim 11, wherein the clamping member is a captive nut.

13. The oscillating power tool of claim 9, further comprising:

a biasing member configured to bias the flange toward the clamping member.

14. The oscillating power tool of claim 9, wherein the flange includes a first notch and a second notch which are arranged radially on the mounting side of the flange, the first notch having a first depth, the second notch having a second depth, the second depth being greater than the first depth.

15. The oscillating power tool of claim 9, wherein the flange includes a counterweight for counterbalancing an accessory tool attached to the oscillating interface.

16. The oscillating power tool of claim 9, wherein the flange includes a slot and a plurality of notches which are arranged parallel to each other and perpendicular to a longitudinal dimension of the slot, and

wherein the flange includes an accessory tool mounting portion which is configured to retain an accessory tool on the flange.
