Abstract

An attachment is configured to be used with a hand-held rotary power tool. The attachment includes a housing, a sanding disk, and a cap. The housing has a first portion hingedly connected to a second portion so as to be rotatable into a closed configuration. The housing receives the sanding disk when the housing is positioned in the closed configuration. The cap is coupled to the first and second portions of the attachment housing when the housing is positioned in the closed configuration. The cap includes an end that is closed by an access portion and a guiding portion. The access portion includes an opening configured to provide access through the cap to the abrasive surface of the sanding disk when the cap is coupled to the housing.

First claim

What is claimed is:

1. An attachment configured to be used with a hand-held rotary power tool, the attachment comprising:
an attachment housing including a first portion and a second portion configured to be hingedly connected together so as to be rotatable between a first configuration and a second configuration, the attachment housing being substantially shaped as a hollow cylinder defining a cavity and being centered about a longitudinal axis when the first and second portions are in the second configuration;
a sanding disk configured to be positioned in the cavity of the attachment housing, the sanding disk having a substantially planar abrasive surface that is substantially circularly shaped and is configured to rotate about an axis of rotation, the axis of rotation being substantially parallel to the longitudinal axis; and
a cap configured to be coupled to the first and second portions of the attachment housing, the cap being substantially shaped as a hollow cylinder including an end that is closed by an access portion and a guiding portion, the access portion defining an access surface that is substantially parallel to the abrasive surface of the sanding disk, the guiding portion defining a guiding surface that is not parallel to the abrasive surface of the sanding disk, the access portion including an opening formed through the access surface and configured to provide access to the abrasive surface of the sanding disk when the cap is coupled to the attachment housing.

2. The attachment of claim 1 , wherein:
the attachment housing includes at least one channel; and
the cap includes at least one sliding tab configured to be slidably received in the at least one channel.

3. The attachment of claim 2 , wherein:
the at least one channel includes a trunk, a first branch, and a second branch; and
the at least one sliding tab is configured to be slidably received in the trunk and selectively rotatable into the first branch and the second branch.

4. The attachment of claim 3 , wherein:
when the at least one sliding tab is rotated into the first branch, the access surface is spaced apart from the abrasive surface of the sanding disk by a first distance; and
when the at least one sliding tab is rotated into the second branch, the access surface is spaced apart from the abrasive surface of the sanding disk by a second distance that is different than the first distance.

5. The attachment of claim 1 , wherein the guiding surface is arranged at an angle of approximately 45° relative to the access surface.

6. The attachment of claim 1 , wherein the opening is surrounded by the access surface.

7. The attachment of claim 1 , wherein:
the first portion of the attachment housing includes a first engagement member; and
the second portion of the attachment housing includes a second engagement member configured to be selectively engaged with the first engagement member to retain the attachment housing in the second configuration.

8. The attachment of claim 1 , wherein:
the first portion of the attachment housing includes a first snap portion; and
the second portion of the attachment housing includes a second snap portion configured to be snap fitted with the first snap portion to form a hinge that hingedly connects the first portion and the second portion.

9. The attachment of claim 8 , wherein:
the first portion and the second portion are rotatable relative to one another about a hinge axis of the hinge; and
the hinge axis is substantially parallel to the longitudinal axis.

10. The attachment of claim 3 , wherein:
the at least one channel further includes a third branch; and
the at least one sliding tab is selectively rotatable into the third branch.

11. A hand-held rotary power tool, comprising:
a tool housing;
a rotatable mandrel received within the tool housing; and
an attachment, including:
an attachment housing configured to be coupled to the tool housing, the attachment housing including a first portion and a second portion configured to be hingedly connected together so as to be rotatable between a first configuration and a second configuration, the attachment housing being substantially shaped as a hollow cylinder defining a cavity and being centered about a longitudinal axis when the first and second portions are in the second configuration;
a sanding disk configured to be coupled to the mandrel, the sanding disk configured to be positioned in the cavity of the attachment housing, the sanding disk having a substantially planar abrasive surface that is substantially circularly shaped and is configured to rotate about an axis of rotation, the axis of rotation being substantially parallel to the longitudinal axis; and
a cap configured to be coupled to the first and second portions of the attachment housing, the cap being substantially shaped as a hollow cylinder including an end that is closed by an access portion and a guiding portion, the access portion defining an access surface that is substantially parallel to the abrasive surface of the sanding disk, the guiding portion defining a guiding surface that is not parallel to the abrasive surface of the sanding disk, the access portion including an opening formed through the access surface and configured to provide access to the abrasive surface of the sanding disk when the cap is coupled to the attachment housing.

12. The tool of claim 11 , wherein:
the attachment housing includes at least one channel; and
the cap includes at least one sliding tab configured to be slidably received in the at least one channel.

13. The tool of claim 12 , wherein:
the at least one channel includes a trunk, a first branch, and a second branch; and
the at least one sliding tab is configured to be slidably received in the trunk and selectively rotatable into the first branch and the second branch.

14. The tool of claim 13 , wherein:
when the at least one sliding tab is rotated into the first branch, the access surface is spaced apart from the abrasive surface of the sanding disk by a first distance; and
when the at least one sliding tab is rotated into the second branch, the access surface is spaced apart from the abrasive surface of the sanding disk by a second distance that is different than the first distance.

15. The tool of claim 11 , wherein the guiding surface is arranged at an angle of approximately 45° relative to the access surface.

16. The tool of claim 11 , wherein the opening is surrounded by the access surface.

17. The tool of claim 11 , wherein:
the first portion of the attachment housing includes a first engagement member; and
the second portion of the attachment housing includes a second engagement member configured to be selectively engaged with the first engagement member to retain the attachment housing in the second configuration.

18. The tool of claim 11 , wherein:
the first portion of the attachment housing includes a first snap portion; and
the second portion of the attachment housing includes a second snap portion configured to be snap fitted with the first snap portion to form a hinge that hingedly connects the first portion and the second portion.

19. The tool of claim 18 , wherein:
the first portion and the second portion are rotatable relative to one another about a hinge axis of the hinge; and
the hinge axis is substantially parallel to the longitudinal axis.

20. The tool of claim 13 , wherein:
the at least one channel further includes a third branch; and
the at least one sliding tab is selectively rotatab
