  • Universal joint
    Patent number: 8403763
    Abstract: A universal joint includes a rotating member having a pivotal portion received in a compartment defined by a peripheral wall at an end of a base. The rotating member includes a coupling portion and an interconnecting portion between the pivotal portion and the coupling portion. The interconnecting portion has a minimum diameter smaller than the maximum diameter of the pivotal portion but not smaller than a width of the coupling portion. A groove extends through the pivotal portion. A pin is extended through the peripheral wall of the base and the groove. The pivotal portion is pivotable relative to the base through an angle in the order of 90°.

  • UNIVERSAL JOINT
    Publication number: 20100004064
    Abstract: A universal joint includes a base having a receiving recess and two holes defined through the base and communicating the receiving recess. A pivotal member includes a connection portion, a pivotal portion and a neck portion connected between the connection portion and the pivotal portion which is pivotably engaged with the receiving recess. A passage is defined through the pivotal portion and a pin extends through the two holes and the passage to pivotally connect the pivotal member to the base. The neck portion has a lowest point, and a shortest distance defined between the lowest point and a transverse line extending through an axial center line of the passage and perpendicular to the pivotal member is larger than a radius of the pivotal portion.
