Routing guide

Claim 2

A guide device for portable routers comprising: a base for receiving a workpiece; a pair of straight parallel longitudinally extending tracks spaced apart on said base defining an area to receive a workpiece therebetween; at least one elongate slotted guide member for removably receiving a portable router, the guide member extending between the tracks above the base traversing the area for receiving the workpiece, and having a substantially flat and unobstructed surface adjacent both sides of its slot along the length of the guide member which traverses the area for receiving the workpiece, such flat surface being of sufficient width to receive and support a portable router, and the slot of the guide member having a width to receive the bit of a router whereby a router may be placed in position to operate on a workpiece positioned on said base by placing it atop said guide member for sliding movement up and down the guide members with its bit extending through the slot, and may be removed from such operative position by lifting it from the guide member; a carriage on each track, each carriage being rotatably secured to the guide member, and each carriage being slidably engaged with its respective tracks, whereby the guide member may be situated at selected locations and angular dispositions with respect to the tracks; locking means for securing the carriages and guide member in fixed position during operations; and calibrated indicator means associated with each track whereby providing visible indications or location along each track.

Claim 3

The device of claim 1, further comprising downward facing surfaces on the track and horizontally extending portions on each said carriage engaging the downward facing surfaces of said tracks to secure each carriage in sliding engagement with its respective track.

Claim 4

The device of claim 1, in which the guide member is characterized by a channel cross-section, so that upstanding flanges are provided along the edges of the guide member for receiving a router therebetween.

Claim 5

A portable router and guide comprising: a base for receiving a workpiece; a pair of straight parallel longitudinally extending tracks spaced apart on said base defining an area to receive a workpiece therebetween; at least one elongate slotted guide member for removably receiving a portable router, the guide member extending between the tracks above the base traversing the area for receiving the workpiece, and having a substantially flat and unobstructed surface adjacenT both sides of its slot along the length of the guide member which traverses the area for receiving the workpiece, such flat surface being of sufficient width to receive and support a portable router, and the slot of the guide member having a width to receive the bit of a router whereby a router may be placed in position to operate on a workpiece positioned on said base by placing it atop said guide member for sliding movement up and down the guide members with its bit extending through the slot, and may be removed from such operative position by lifting it from the guide member; a portable router removably positioned over the guide member with its bit extending downwardly through the guide member slot; a carriage on each track, each carriage being rotatably secured to the guide member, and each carriage being slidably engaged with its respective tracks, whereby the guide member may be situated at selected locations and angular dispositions with respect to the tracks; locking means for securing the carriages and guide member in fixed position during operations; and calibrated indicator means associated with each track whereby providing visible indications of location along each track.

Claim 6

A portable router and guide comprising: a base for receiving a workpiece; a pair of straight parallel longitudinally extending tracks spaced apart on said base defining an area to receive a workpiece therebetween; at least one elongate slotted guide member for removably receiving a portable router, the guide member extending between the tracks above the base traversing the area for receiving the workpiece, and having a substantially flat and unobstructed surface adjacenT both sides of its slot along the length of the guide member which traverses the area for receiving the workpiece, such flat surface being of sufficient width to receive and support a portable router, and the slot of the guide member having a width to receive the bit of a router whereby a router may be placed in position to operate on a workpiece positioned on said base by placing it atop said guide member for sliding movement up and down the guide members with its bit extending through the slot, and may be removed from such operative position by lifting it from the guide member; a portable router removably positioned over the guide member with its bit extending downwardly through the guide member slot; a carriage on each track, each carriage being rotatably secured to the guide member, and each carriage being slidably engaged with its respective tracks, whereby the guide member may be situated at selected locations and angular dispositions with respect to the tracks; locking means for securing the carriages and guide member in fixed position during operations; and calibrated indicator means associated with each track whereby providing visible indications of location along each track.

Claim 7

The device of claim 4, further comprising downward facing surfaces on the track and horizontally extending portions on each said carriage engaging the downward facing surfaces of said tracks to secure each carriage in sliding engagement with its respective track.

Claim 8

The device of claim 4, in which the guide member is characterized by a channel cross-section, so that upstanding flanges are provided along the edges of the guide member for receiving a router therebetween.
