Abstract
A holding device for holding a tool includes a holding block having a central opening formed from a stack of laminated members secured together. The block includes holes extending away from the central opening. A pair of support plates are secured to the block and are secured at right angles to one another. Key hole slots are in one of the support members and have a first bore containing a slug and a second bore at right angles thereto. A threaded member extends through the other of the support members, through the second bore, and is threaded into the slug within the first bore.
Claims25
A holding device for selectively retentively holding an object, the holding device comprising:
- a plurality of laminate members each having a first flat surface, a second flat surface parallel to the first flat surface, a parametric edge, a central opening extending through each of the laminate members in a direction perpendicular to the first and second flat surfaces, and a slot extending completely through the laminate member from the central opening to the parametric edge so as to create a first laminate side and a second laminate side spaced apart from one another across the slot;
- securing means holding the plurality of laminate members together in a stack to form a laminated block having a central block opening formed by the central openings of the plurality of laminate members being registered with one another and having a block slot formed by the slots of the plurality of laminate members being registered with one another;
- the block slot forming a first block side and a second block side spaced apart from one another across the block slot;
- the central block opening having a shape and size that corresponds generally to the object so as to permit the object to be fitted within the block opening of the laminated block;
- a tightening member engaging the first and second block sides and being movable to cause flexing of the laminated block from a loose position permitting the object to move within the registered openings of the laminated block to a tight position moving the opposite sides of the block stop closer together to clamp the laminated block around the object and hold the object against movement relative to the laminated block.

In combination:
- a router;
- a laminated block having an opening extending through the laminated block and surrounding a portion of the router;
- the laminated block having a radial slot extending from the opening in a radial direction and forming first and second separate sides of the laminated block on opposite sides of the radial slot;
- a tightening member engaging the first and second separate sides of the laminated block and being movable from a loose position wherein the laminated block loosely surrounds the portion of the router to a tightened position wherein the first and second separate sides of the laminated block move toward one another and the block tightly clamps around the portion of the router;
- the laminated block being formed from a plurality of laminate members, each comprising first and second opposite laminate faces, the plurality of laminate members being attached together in face to face relation to one another.
2 more elements
A holding device for a router comprising:
- a holding block having an opening for receiving the router, the holding block having first and second spaced apart block ends on one side of the opening;
- a tightening member engaging the first and second block ends and being movable from a loose position to a tightened position flexing the first and second blocks toward one another to reduce the size of the opening;
- a base plate having a planar base plate surface;
- a first support plate lying in a first plane perpendicular to the planar base plate surface and having a first securing member attaching a first support plate edge to the base plate surface;
- a second support plate lying in a second plane perpendicular to the planar base plate surface and having a second securing member attaching a second support plate edge to the base plate surface;
- a third securing member attaching the first and second support plates to one another so that the first plane of the first support plate is perpendicular to the second plane of the second support member
- the holding block being operatively attached to both of the first and second support plates.
4 more elements
A method for assembling a holding device for a router comprising:
- forming a plurality of laminate plates, each having opposite faces, a parametric edge, a router opening extending there through along a router opening axis perpendicular to the first and second flat surfaces, and a slot extending from the router opening to the parametric edge to create a first laminate end and a second laminate end spaced across the slot from one another;
- attaching the plurality of laminate members together in face to face relation with one another and with the router openings and the slots of each of the laminate members registered with one another, respectively, thereby forming a laminated block having a block opening formed by the registered router openings, a block slot formed by the registered laminate slots, and first and second block ends spaced apart from one another across the block slot;
- engaging the first block end and the second block end with a tightening member capable of moving from a loose position to a tightened position flexing the first block end and the second block end towards one another to reduce the size of the block opening.
