Definitions

  • the present invention relates to attachments. More particularly, the present invention relates to adjustable attachments which can be used with routers making them safer and more effective.
  • a router is a tool which is used for cutting precise edges, grooves or shapes in a workpiece.
  • guide mechanisms known in the prior art which permit a straight or curved cut or groove to be made in a workpiece, problems arise when one is faced with the task of making a plurality of identical grooves in parallel along the length of a workpiece or an array of identically positioned grooves in a sequence of workpieces and other problems arise with more complex structures such as mortice and tenon joints.
  • None of the prior art sufficiently addresses the need for a simple and versatile attachment for a router which can cut a wide range of shapes using a pattern that is the same size as the final shape required and including both pieces of mortice and tenon joints.
  • This improved attachment uses a guide pin running in a pattern positioned alongside the workpiece, to guide the movement of the cutter, rather than a template set between the router and the workpiece.
  • the invention uses a series of rotating struts or plates with or without horizontal sliders to ensure that the router and guide pin running in the pattern are maintained in the same orientation throughout all movements of the router.
  • a router attachment which comprises a movable carriage which can hold a router and a guide pin, which carriage is attachable to a router base plate by a controlling attachment means so that a router held in the carriage is able to move in two orthogonal directions (X and Y directions) and in which the attachment means comprises a pair of spaced apart components which are either fixed relative to the base plate or are able to move relative to the base plate in one direction (the X direction) the two components being constrained to move at a constant relative angular rotation to each other about a pair of pivot points, each component is pivotally connected to a connector which is connected to the carriage and which, when the component is fixed relative to the base plate, is pivotally connected to the carriage.
  • controlling mechanism would generally consist of:
  • the component can be in the form of a plate which, when the component is fixed relative to the base plate is connected to the base plate about a pivot point and connected to the carriage by a further pivotal connection.
  • each component is pivotally and slidably connected to a bar attached to the router base plate so they can move along the bar slidably whilst being held a fixed distance apart.
  • These pivot points can be held a fixed distance apart by being attached to a sleeve slidably mounted on the bar.
  • the bar can be in the form of a rod or a similar structure which can either permit rotation of the sleeve thereby allowing the router cutter to be rotated vertically clear of the base or, if sleeve is restrained from rotating, the carriage and router complete can be removed clear of the base with the use of detachable mounting pins and or sockets.
  • the base plate preferably comprises a moulded or machined plate with a recess and perforation through formed in it, preferably there is a movable carriage which holds the router and guide pin.
  • the carriage has an extended block below the main plate holding the router columns thereby lowering the point of router support and extending maximum projection of the cutter into the workpiece.
  • the block sits within the recess and limits overall movement of the carriage, whilst the perforation allows the cutter to pass through the base into the workpiece located below.
  • the carriage is movable connected to the controlling mechanism by either fixed arms or detachable couplings. This enables the carriage and router to be rotated vertically clear of the recess or removed from the base.
  • the router base can be a movable base or it can be a base fixed to a workbench or other equipment.
  • Components to the side of the bar remote from said recess in order to give a greater range of movement i.e. the component can move over and/or under the bar to give a greater range of movement.
  • a second recess for an adjustable pattern holder which holds the pattern firmly and enables it to be moved relative to the base to achieve fine adjustment in positioning of the pattern within the recess and with respect to the workpiece as well as allowing a series of parallel cuts or grooves to be made.
  • the guide pin diameter be varied to match or relate to the diameter of the cutter being used.
  • the pin is therefore slidably mounted in the vertical direction within a holder attached directly to the carriage. In general operation the mounting height will depend upon the thickness and construction of the pattern, and be locked during any particular routing operation. Where the plunge depth of the router is being controlled by the attachment/device from the shape of the pattern the guide pin may be allowed to slide vertically thereby following the contours of the pattern.
  • the pivots forming the pivot points are detachable so that the router plate can be removed; this enables a range of routers or similar tools to be used with the attachment and enables the router to be easily removed from the attachment.
  • the carriage can be rotated clear of the base.
  • Routers can be used to drill a series of vertical holes in a workpiece for dowels but up to now positioning has been difficult with the smaller sized holes used for dowels due to the likelihood of damaging the pattern.
  • the use of guide bushes effectively limit the minimum distance between holes. It is not necessary to have the cutter the same size as the dowel it can be smaller. Where many dowel holes are required the router could be replaced with a vertical drill attached to the holding plate.
  • the attachment can be held on a work bench by conventional holding devices or can be secured to a "Workmate" type work bench with the jaws of the "Workmate” being used to hold the workpiece.
  • the attachment can be clamped to the piece to be worked by means of clamps such as G clamps; this is useful with large objects such as kitchen units and doors.
  • the router cutting bit can be raised and lowered into the material to be worked so that the depth of cut can be controlled.
  • This facility is already incorporated in the standard plunge type router.
  • the cutter depth be varied in relation to different levels or contours within the pattern automatic depth control could be included within the router holding device that would raise or lower the cutter according to information received from an electronic sensor mounted within the guide pin or directly from the vertical movement of the guide pin.
  • the vertical movement of the cutter could the be magnified by a servo mechanism or similar device.
  • the carriage When the router plate is rotatably attached to the bar e.g. via a sleeve, the carriage can be rotated about the bar and so lifted away from the base plate The router can be locked in position at any angle in relation to the base plate so that angled grooves etc. can be cut, in addition this embodiment enables the router blade to be easily changed without removing the attachment from the material being worked.
  • clamping arrangements used with the attachment of the present invention which facilitates the attachment being used with a range of size of objects and applications.
  • the material to be worked on e.g. a door into which a lock is to be inserted or into which hinges are to be attached, is clamped to the device.
  • a pattern for the size of slot into which the lock is to be inserted is positioned under the guide pin, the door is fixed so that the location of the router is above the edge of the door where the lock is to be inserted.
  • the router is started and lowered into contact with the door and the guide pin guided over the pattern so that the router blade cuts a slot in the door of the right dimensions.
  • the edge of the door is positioned under the router and a pattern of the hinge dimensions fixed under the guide pin so that, as the guide pin moves over the pattern, the right shaped cut out is formed in the door to receive the hinge.
  • the depth of cut is controlled by the moving router cutter as in conventional routers.
  • the attachment can be used with a router to cut for example a mortice and tenon joint, in which case the same pattern can be used for cutting the mortice and the tenon, so that to cut the mortice the guide pin is moved around the outside of the pattern and, to form the mortice, the guide pin is moved around the inside of the pattern.
  • the pattern consists of a plate with a slot formed in it corresponding to the size of the mortice with a removable plug in it which corresponds to the tenon. With the plug out or lowered below the surface of the plate a mortice can be cut and with the plug raised and the guide pin following round the plug the tenon can be formed. It is important that the plate can be turned over both left to right and top to bottom so that cuts make matching pairs or where cuts are made at an angle to the plate can be exactly matched.
  • the guide pin can be made from high strength materials except where the diameter is very small, generally the guide pin can be made from standard diameter extruded aluminium rod with the end part turned to the required diameter.
  • This low cost solution permits a wide range of guide pin diameters to be held, thereby allowing tight control on tolerances to be achieved, by simply changing the guide pin diameter. There is no need to remove the carriage from the device in order to change the guide pin and so achieved the desired tolerance.
  • a guide pin with diameter greater than cutter by 0.01mm will decrease a mortise dimension by 0.005mm for each face i.e. 0.01mm overall.
  • the same combination increases the dimension on the component by the same amount.
  • Using this offsetting effect would be also possible to cut complex shapes replicating release tapers complete with internal and external radii as seen with injected moulded plastic components, by using a single pattern combined with different cutters and guide pins of different diameters.
