    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.

    Abstract: An improved load-supporting system for scaffolding, lengths of elongated stock used in the construction industry, tools, and other loads includes a unique system for adjusting the height at which a load is held above a supporting surface. The invention includes a column having a column axis of alignment and at least one sleeve disposed about the column in coaxial sliding engagement therewith. The sleeve has an appendage forming a radially inwardly facing jaw and a jamming washer that surrounds the column and extends into the jaw. The height at which a load is held above a supporting surface is varied by adjusting the relative longitudinal positions of the sleeve and the column. By momentarily forcing the jamming washer into perpendicular alignment relative to the column, incremental adjustment of the relative positions of the sleeve and the column occur.

  • Patent number: 4545618
    Abstract: A head-rest device is disclosed which comprises a head-rest stay, a head-rest holder mounted to a seat back and a lock mechanism provided within the head-rest holder. The head-rest stay is inserted into its associated head-rest holder. The head-rest stay is formed with two or more pairs of slotted recesses on its circumferential surface. Such pair of slotted recesses are located at required intervals in a vertical direction from each other and correspond to each other in a staggered manner. An engagement body, which has a required thickness and is formed with a stay insertion bore having a diameter substantially equal to that of the head-rest stay, is inclinably inserted via a spring into the head-rest holder. A retaining member is also provided which is capable of retaining the engagement body in its inclined position in which the upper and lower edge portions of the stay insertion bore are engaged with a pair of slotted recesses respectively.

  • Patent number: 4398766
    Abstract: A removable seat for attachment to a support, such as the thwart of a boat, having a mounting housing rotatably secured to the base of the seat. A plurality of support-engaging members are slidably disposed in the housing for removably attaching the seat to the support. Each of the support-engaging members includes a cylindrical bar having an L-shaped end portion to which a rubber disk is attached. Locking means releasably secure each of the support-engaging members to the housing. Each locking means includes a lever which is pivotally attached to the housing and has detent means formed therein for slidably receiving one of the support-engaging members. A resilient means, such as a spring, is disposed between a pair of levers for urging the detent means carried thereby into frictional engagement with the support-engaging member.

  • Patent number: 4314591
    Abstract: An improved log splitter for home use incorporating a load-responsive clamping mechanism of the type that utilizes a stack of locking plates surrounding a cylindrical member to which the plates are to be clamped by a tilting action. The plates are prevented from chewing up the surface of the cylindrical member by a pair of shoes positioned on opposite sides of the cylindrical member and within the openings in the locking plates. One of the shoes is smooth and adapted to move longitudinally on the cylindrical member during the application of clamping force and the other is rough and remains stationary during the clamping action.
