  • Patent number: 8608398
    Abstract: The spherical joint with internal brake has a controlled actuator that selectively brakes relative motion between interior members and an outer shell of the spherical ball joint. A shaft extending from the internal members can be stopped at any rotational position relative to the shell. The internal members may include a central spherical sectioned member sandwiched by a pair of symmetrically opposed peripheral spherical sectioned members, which selectively act as brakes when an actuator in the central member is energized. The energized actuator has a dual piston that pushes outwardly on the pair of opposed peripheral segments, which increases friction between the peripheral segments and an interior wall of the spherical shell to brake the system. The shaft extends from the central spherical sectioned member through an aperture in the shell. The size of the shell aperture determines the range of rotational motion of the shaft.

  • Patent number: 5951195
    Abstract: In the ball pivot arrangement for a ball joint described in the specification, an essentially spherical upper region and an essentially bar-shaped lower region are joined by friction welding, the spherical region being capable of being mounted in a joint cup or joint socket to form a ball joint and the bar-shaped region constituting a joint rod. The costs involved in producing the ball pivot arrangement are reduced and the ball pivot arrangement is more effectively adaptable to different stresses because each of the components can be machined or hardened separately to provide required dimensions or hardness before assembly.

  • Patent number: 5568993
    Abstract: A highly rigid structure is provided using six struts connected at three er and three lower nodes to upper and lower support structures. The joint assemblies are formed by half-spherical balls attached to the ends of each of the struts, and retained within cylindrical apertures, such that the center lines of the struts intersect at the nodes. Bending loads on the struts are thus eliminated, while the design and construction of the structure is substantially simplified.

  • Patent number: 5197926
    Abstract: A guard for a swing connection comprised of a hook which hooks through the eye of a connector member includes a pair of rigid shells which are slotted at their edges to provide clearance for the hook and the connector member so that the shells can be clamped to opposite sides of the hook and engaged together edge to edge so as to form an enclosure which completely surrounds the hook and its connection to the connector member. The guard prevents finger injuries due to the pinch point at the connection between the hook and the connector member. It also maintains the relative position of the hook and connector member so that the connector member cannot become disengaged accidentally from the hook. In addition, the guard may be shaped and its exterior surface treated so that the guard adds a decorative element to the swing connection.

  • Patent number: 4995755
    Abstract: A ball joint includes a pair of generally hemispheric head members including facing surfaces. A bearing member is disposed between the facing surfaces. One of the head members is connected to a ball stud, the other includes a shank hole through which the ball stud passes. Both head members are enclosed in a ball seat which is deformed into conformity with a generally spherical outer surface of the combined first and second head members by a socket that is formed about them. An elastic member between the socket and the ball seat applies an axial force to said first and second head members, whereby a substantial preload on the ball joint permits take-up of wear during use.
