Abstract
A device for support of a portable router above a work table so as to convert a portable router into a pin router assembly. The device includes a mounting plate which is directly attached to the base portion of the router. The mounting plate is formed integral with a support carriage assembly that is mounted in a housing assembly to permit the router to be smoothly and accurately positioned above the work table in preselected positions. A guide pin is carried in a block assembly that is received in the work table in a manner which permits the adjustment of the guide pin into alignment with the router chuck.
Claims20
A router table for support of a portable router above a work surface, comprising:
- (a) a work table having a generally horizontal upper work surface;
- (b) a support arm assembly secured to said work table, said support arm assembly including an upper support arm portion having an inner end which extends above a central portion of said work surface;
- (c) a carriage mounting housing assembly secured to said inner end of said upper support arm portion, said carriage mounting assembly having a dovetail shaped recess defined in an end portion thereof, said end portion having a vertically extending opening communicating said recess with a cavity defined within said carriage mounting housing assembly;
- (d) a spur gear positioned within said cavity for rotation about a generally horizontal axis in facing relationship to said opening;
- (e) a support carriage assembly including a dovetail shaped slide portion slidably received within said recess;
- (f) a geared rack mounted to said slide portion so as to extend into said opening and mesh with said spur gear such that rotational movement of said spur gear is translated into vertical movement of said support carriage assembly;
- (g) a wear surface insert positioned between said slide portion and a surface of said recess so as to facilitate controlled vertical movement of said slide portion within said recess;
- (h) a bearing plate positioned between a portion of said wear surface insert and a surface of said recess;
- (i) locking means for selectively applying inward pressure to said bearing plate so as to selectively clamp said slide portion within said recess and thereby prevent vertical movement of said slide portion within said recess;
- and
- (j) a mounting means associated with said support carriage assembly for attachment of a router thereto above said work surface.
A router table for support of a portable router above a work surface, comprising:
- (a) a work table having a generally horizontal upper work surface;
- (b) a support arm assembly secured to said work table, said support arm assembly including an upper support arm portion which extends above and over said work surface;
- (c) a carriage mounting housing assembly secured to said upper support arm portion;
- and
- (d) a support carriage assembly movably mounted to said carriage mounting housing assembly so as to permit vertical movement of said support carriage assembly relative to said work surface, said support carriage assembly including a generally horizontal mounting plate extending over a portion of said work surface, said mounting plate having a central opening for accommodating the router chuck and bit, said mounting plate also including means associated therewith for accommodating attachment of the base portion of the router directly to said mounting plate.
A router table for support of a portable router above a work surface, comprising:
- (a) a work table having a generally horizontal upper work surface;
- (b) a support arm assembly secured to said work table, said support arm assembly including as upper support arm portion which extends above and over said work surface;
- (c) a carriage mounting housing assembly secured to said upper support arm portion;
- (d) a support carriage assembly for attachment of the router thereto mounted to said carriage mounting housing assembly above a central portion of said work surface so as to permit selective vertical movement thereof relative to said work surface;
- and
- (e) a guide pin block assembly mounted within a recess in said central portion of said work surface for support of a vertical guide pin therein, said guide pin block assembly permitting the selective adjustment of the location of said guide pin along at least either of two perpendicular axes.
