Abstract
A power tool accessory system has a first accessory with a first connector for attaching the accessory to the power tool, and a second connector for attaching a second accessory to the first accessory. Preferably both attachment means are manually operable whereby the first accessory may be attached to a power tool and to a second accessory without the use of tools.
Claims18
An accessory system for attachment to a rotary cutting tool, the accessory system comprising:
- a depth adjuster having an upper member and a lower member, one of said upper and lower members having a substantially vertical sleeve and the other having a substantially vertical rail engagable in said sleeve to movably connect said upper and lower members to one another, said rail lockable within said sleeve;
- said upper member having a locking collar for engaging the rotary cutting tool, said locking collar having a closed position, an open position, and manual locking means for urging said collar towards said closed position from said open position to engage the cutting tool;
- said lower member having a generally circular bottom rim with a generally circular outer perimeter, and having a channel extending around substantially all of said generally circular outer perimeter;
- and
- a second accessory removably engaged with said lower member channel.

A power tool accessory system comprising:
- a first accessory having generally circular top and bottom perimeters, said first accessory having a collar proximate said top perimeter for removably connecting said first accessory to the power tool, said collar having a closed and an open position and locking means for urging said collar towards said closed position, said first accessory having a channel along at least a portion of said circular perimeter for removably attaching said first accessory to a second accessory, and said first accessory comprising an upper member and a lower member, said upper and lower members having cooperating connecting means for movably connecting to one another;
- and
- a second accessory, said second accessory having at least a connector for releasably engaging said first accessory bottom perimeter channel to attach said second accessory to said first accessory, said second accessory having a lower perimeter, a channel along at least a portion of said lower perimeter for attaching a third accessory to said second accessory, said second accessory lower perimeter channel having a cross direction width substantially the same as the cross direction width of first accessory bottom perimeter channel.
A power tool accessory system comprising:
- a first accessory having generally circular top and bottom perimeters, said accessory having a first connector for removably connecting said first accessory to the power tool, said first connector proximate said top perimeter, and said first accessory having a second connector for removably attaching said first accessory to a second accessory, said second connector extending around substantially all of said generally circular bottom perimeter;
- a second accessory comprising a primary connector for engaging said first accessory second connector to removably attach said second accessory to said first accessory, and a channel for removably attaching said second accessory to a third accessory, said channel substantially the same size as said first accessory second connector;
- and,
- a third accessory, said third accessory having at least one spring lever having a stud for engaging either one of said second accessory channel or said first accessory second connector.

A rotary tool accessory system for a rotary tool that has a cutting bit and a circular abutment, the accessory system comprising:
- a depth adjuster for adjusting the cutting depth of the rotary cutting tool, said depth adjuster having an upper and a lower member movably connected to one another, said depth adjuster having generally circular top and bottom perimeters, said depth adjuster having a locking collar proximate the top of said upper member for engaging the rotary tool circular abutment, said depth adjuster having a central opening for passing at least a portion of the cutting bit, said central opening passing through both of said top and bottom perimeters, and said depth adjuster having a channel along at least a portion of said lower perimeter of said lower member for removably attaching said depth adjuster to a second accessory;
- and
- a second accessory, said second accessory comprising a vacuum adaptor having a port for communicating with a vacuum, said vacuum accessory having at least a spring lever for engaging said depth adjuster channel, and said vacuum adaptor having a secondary connector for removably attaching a third accessory to said vacuum adaptor.
An accessory system for attachment to a rotary cutting tool, the accessory system comprising:
- a depth adjuster having an upper member and a lower member, one of said upper and lower members having a substantially vertical sleeve and the other having a substantially vertical rail engagable in said sleeve to movably connect said upper and lower members to one another, said rail lockable within said sleeve, said upper member having a locking collar for engaging the rotary cutting tool, said locking collar having a closed position, an open position, and manual locking means for urging said collar towards said closed position from said open position to engage the cutting tool, said lower member having a generally circular bottom rim and having a channel extending around substantially all of said generally circular bottom rim for attaching a second accessory;
- and,
- a vacuum adaptor having a vacuum port for connection to a vacuum source, said vacuum adaptor having a plurality of integral spring lever connectors for engaging said depth adjuster channel;
- said vacuum adaptor having a generally circular bottom rim with a channel connector for attaching a third accessory to said vacuum adaptor, said vacuum adaptor channel connector having substantially the same diameter, channel width, and channel depth as said depth adjuster channel.

A power tool accessory system comprising:
- a depth adjuster having top and bottom perimeters vertically moveable relative to one another, a first connector proximate said top perimeter for attaching to the power tool, and a second connector proximate said bottom perimeter;
- second and third accessories, each of said second and third accessories having a primary connector for attaching to said depth adjuster second connector whereby either one of said second or third accessories may be attached to said depth adjuster.
A power tool accessory system comprising:
- a first accessory having generally circular top and bottom perimeters, having a first connector proximate said top perimeter for removably connecting said first accessory to the power tool, having a channel extending around substantially all of said generally circular bottom perimeter for removably attaching said first accessory to a second accessory;
- and,
- a second accessory having a body and a plurality of spring levers integral with said body, each of said spring levers comprising a lever with two ends, said lever integrally connected to said body by a cross member, said plurality of spring levers for cooperating with said channel to removably attach said second accessory to said first accessory.
