Abstract
The present invention relates to router fixture having a base with a base aperture and a pair of slidably adjustable horizontal guides. The router fixture is designed to receive a precut template which defines the area of movement for a router used on the router fixture. The template fits into the guides and defines the area of separation between the guides and also provides an indication as to the area of a workpiece which is to be cut out on the workpiece.
Claims11
A router fixture which is positionable over a workpiece comprising:
- a baseplate having a top surface, a bottom surface and a baseplate aperture extending from the top surface to the bottom surface;
- a pair of horizontally slidable guides on the top surface of the baseplate which are adjustable to define an area for receiving a template in a fixed horizontal position, said template having a template aperture which is positionable over the baseplate aperture and which defines the area to be cut out of the workpiece;
- and
- vertical template retention means for retaining the insertable template in a fixed vertical position within said pair of horizontally slidable guides,
- whereby the positioning of the template in the horizontally slidable guides results in the formation of a pair of horizontal guides for restraining movement of the router such that the router will not cut out any area of the workpiece which is not exposed by the template aperture.
A guide fixture for cutting a predetermined portion of a workpiece located below said guide fixture with a cutting device, said cutting device having a cutting member which extends from said cutting device and where said cutting member functions to cut a portion of the workpiece, said guide fixture comprising:
- a base having a top surface, a bottom surface opposite said top surface and an aperture extending from said top surface to said bottom surface, wherein said cutting device may be placed above said top surface such that said cutting member of said cutting device extends through the aperture to the workpiece located below the bottom surface of the base;
- and
- adjustable guide means coupled to the top surface of the base for receiving a template which defines the outermost boundaries of movement for the cutting device.
A template for use in a router fixture comprising a baseplate having a top surface, a bottom surface and a baseplate aperture extending from the top surface to the bottom surface, a pair of horizontally slidable guides on the top surface of the baseplate which are adjustable to define an area for receiving the template in a fixed horizontal position, and vertical template retention means for retaining the insertable template in a fixed vertical position within said pair of horizontally slidable guides;
- said template comprising a template aperture which is positionable over the baseplate aperture and which defines the area to be cut out of a workpiece, whereby the positioning of the template in the horizontally slidable guides results in the formation of a pair of horizontal guides for the body of the router such that the router will not cut out any portion of a predetermined area of the workpiece.
A router jig comprising:
- a base having a top surface, a bottom surface opposite the top surface and a base aperture extending from the top surface to the bottom surface;
- a pair of horizontal guide means adjustably attached to the top surface of the base and a pair of vertical guide means attached to the top surface of the base such that the horizontal guide means and the vertical guide means define an area containing at least a portion of the base aperture;
- and
- template means having a template aperture placed within the area defined by the pair of horizontal guide means and the pair of vertical guide means such that the template aperture is locate over the baseplate aperture, said template means including an aperture located over the baseplate aperture which defines the area of a workpiece which is to be exposed for working by a router bit,
- whereby the positioning of the template in the horizontally slidable guides results in the formation of a pair of horizontal guides for the body of a router such that the router will not cut out any area of the workpiece which is not exposed by the template aperture.
