  • Patent number: 6065898
    Abstract: A three tooth kinematic coupling based on having three theoretical line contacts formed by mating teeth rather than six theoretical point contacts. The geometry requires one coupling half to have curved teeth and the other coupling half to have flat teeth. Each coupling half has a relieved center portion which does not effect the kinematics, but in the limit as the face width approaches zero, three line contacts become six point contacts. As a result of having line contact, a three tooth coupling has greater load capacity and stiffness. The kinematic coupling has application for use in precision fixturing for tools or workpieces, and as a registration device for a work or tool changer or for optics in various products.

  • Patent number: 4923322
    Abstract: A structural framework assembly made up of tubular members interconnected by a first connector arrangement which uses a connector having a concave surface pressing against a curved outer surface of a tubular member and having a pair of spreadable arms which are spread by a setscrew to lock inside an end of another tubular member, and a second connector arrangement which uses a connector plate extending into the end of a tubular member with the bottom of the connector plate inserted into a longitudinal slot at the bottom of the tubular member and a top tab on the connector plate inserted into an upper slot at the top of the tubular member. The longitudinal slot at the bottom of the tubular member opens out to the end of the tubular member and the upper slot is located at a distance from the end of the tubular member.

  • Patent number: 4829735
    Abstract: Connecting elements (4) can be inserted into the ends of the individual bar-shaped elements (2), the connecting elements having a projection (13) which engages into an opening (8) at the end of the tube. In that way each individual connecting element (4) can be released even in a framework construction which has already been assembled. The bar-shaped elements (2) are exchangeable and the framework can be broken down into all individual parts.

  • Patent number: 4786203
    Abstract: A connector assembly for joining a horizontal member and a vertical member without the formation of substantial exposed gaps. The assembly includes a base with a saddle surface at one end and an abutment flange at the other end. The base has an aperture between the ends and a slot communicating with the aperture. A locking collar has a bore receiving the base and an inwardly directed annular lip at a first end of the collar. The collar also includes an internal screw thread and an abutment for engaging the flange of the base. Also the assembly includes a locking insert with a body for reception in the base. The insert has extending arms at one end terminating in screw threads and at the other end a holding flange for retaining the horizontal member. A method of using the connector assembly is also disclosed.

  • Patent number: 4783188
    Abstract: A rail connector for use in connecting pipe rails to pipe posts includes a circular tubular member with a reduced sleeve which fits inside a pipe rail and substantially conforms to the inner surface of the pipe rail to provide a tight fit between the connector and pipe rail. The connector includes a mechanism for adjusting the diameter of the sleeve to provide a tight fit between the sleeve and the rail. This mechanism includes a wedge member having substantially rounded sides such that minor deviations in the machining of the sleeve can be accommodated. Also disclosed is a mechanism for locking the pipe rail on the connector so that the pipe cannot be removed.
