  • Patent number: 7086631
    Abstract: A telescoping stand with a quick-release locking mechanism for binding and releasing a telescoping section including an inner extension member that telescopes into and out of an outer receiving member. The locking mechanism includes a pair of opposed actuator members, each with a hole through it and disposed so that the inner extension member of a telescoping pair passes through the holes. When the actuator members are generally perpendicular to the extension member, the extension member slides freely through the holes. In the normal configuration the actuator members are biased so that each is canted with respect to the extension member and so that the two actuator members are canted in opposed directions. In this configuration the actuator members provide a double binding frictional engagement with the extension member to hold it in fixed relation with respect to its associated receiving member.
