Abstract

An accessory tool for an oscillating power tool includes a blade portion including a first lateral edge portion, a second lateral edge portion, and a leading edge portion, the leading edge portion defining a cutting edge. A reinforcement structure extends linearly across the blade portion from a first position located on the leading edge portion proximate the first lateral edge portion to a second position located on the second lateral edge portion and spaced apart from the leading edge portion. The reinforcement structure defines a cutting zone that encompasses a leading region of the blade portion between the reinforcement structure and the leading edge portion, the reinforcement structure being configured to increase a stiffness of the blade portion.

First claim

What is claimed is:

1. An accessory tool for an oscillating power tool, comprising:
an attachment portion configured to mate with an oscillating drive member of a power tool;
a blade portion including a first lateral edge portion, a second lateral edge portion, and a leading edge, the leading edge defining a cutting edge;
a reinforcement structure extending across the blade portion from a first position located on the leading edge proximate the first lateral edge portion to a second position located on the second lateral edge portion and spaced apart from the leading edge,
wherein the reinforcement structure defines a cutting zone that encompasses a leading edge portion of the blade portion between the reinforcement structure and the leading edge, the reinforcement structure being configured to increase a stiffness of the blade portion, and
wherein the cutting zone is less thick than the reinforcement structure.

2. The accessory tool of claim 1 , further comprising a transition portion that offsets the blade portion from the attachment portion.

3. The accessory tool of claim 2 , wherein the second position on the second lateral edge portion is located proximate the transition portion.

4. The accessory tool of claim 1 , wherein the cutting zone has a triangular shape defined by the leading edge, the second lateral edge portion, and the reinforcement structure.

5. The accessory tool of claim 1 , wherein the cutting zone has a thickness 0.05 inches or less.

6. The accessory tool of claim 1 , wherein the reinforcement structure comprises a strip of material attached to the blade portion.

7. The accessory tool of claim 6 , wherein the reinforcement structure is formed of a different material than a material used to form the blade portion.

8. The accessory tool of claim 1 , wherein the reinforcement structure is integral with the blade portion.

9. The accessory tool of claim 1 , wherein a cutout region is defined in the first lateral edge portion of the blade portion on an opposite side of the reinforcement structure from the cutting zone.

10. The accessory tool of claim 9 , wherein the cutout region has a curved shape.

11. The accessory tool of claim 9 , wherein the cutout region has a serpentine shape.

12. An oscillating power tool comprising:
a portable housing;
a motor enclosed within the housing;
a tool holder extending from the housing and configured to be oscillated by the motor about an oscillation axis; and
an accessory tool including:
a mounting portion configured to be releasably retained by the tool holder;
a blade portion including a first lateral edge portion, a second lateral edge portion, and a leading edge, the leading edge defining a cutting edge; and
a reinforcement structure extending linearly across the blade portion from a first position located on the leading edge proximate the first lateral edge portion to a second position located on the second lateral edge portion and spaced apart from the leading edge,
wherein the reinforcement structure defines a cutting zone that encompasses a leading edge portion of the blade portion between the reinforcement structure and the leading edge, the reinforcement structure being configured to increase a stiffness of the blade portion, and
wherein the cutting zone is less thick than the reinforcement structure.

13. The oscillating power tool of claim 12 , wherein the accessory tool further comprises a transition portion that offsets the blade portion from the mounting portion.

14. The oscillating power tool of claim 13 , wherein the second position on the second lateral edge portion is located proximate the transition portion.

15. The oscillating power tool of claim 12 , wherein the cutting zone has a thickness 0.05 inches or less.

16. The oscillating power tool of claim 12 , wherein the reinforcement structure comprises a strip of material attached to the blade portion.

17. The oscillating power tool of claim 16 , wherein the reinforcement structure is formed of a different material than a material used to form the blade portion.

18. The oscillating power tool of claim 12 , wherein a cutout region is defined in the first lateral edge portion of the blade portion on an opposite side of the reinforcement structure from the cutting zone.
