摘要:
An expansion head for expansion tools for hollow work-pieces, particularly for the ends of plastic pipes and metal-plastic composite pipes, comprising a union cap having a guide flange directed radially inward, and a set of expandable jaws of sector-shaped design, each received individually by an inner flange sector overlapping the guide flange so that they are radially movable in the union cap, wherein the set of sector-shaped expandable jaws is movable between a closed state and an expansion state, and in a closed state, an approximately cylindrical lateral area is formed by an envelope of the outer walls of the set of expandable jaws, wherein characterized in that each expandable jaw is provided with at least one recess extending in the direction of the longitudinal axis of the expandable jaws so that in a closed state of the expansion head, the surface of the outer walls of the set of expandable jaws corresponds to 25% to 75% of the surface of the envelope of the outer walls of the set of expandable jaws.
摘要:
A support apparatus includes a first substantially horizontal member positioned adjacent to first and second elongated substantially vertical member members. The first substantially horizontal member has a channel formed in its rear side. The channel is sized and configured to receive wiring for display devices. The first substantially horizontal member is supported or attached to first and second collars positioned on the first and second elongated substantially vertical members such that movement of the first and second collars adjusts a vertical position of the first substantially horizontal member. One or more display devices, such as LCD screens or computer monitors, may be positioned on the first substantially horizontal member. Preferably, each display device positioned on the first substantially horizontal member is connected to the first substantially horizontal member via a connector that utilizes a releasable attachment mechanism that permits an easy removal or connection to the first substantially horizontal member.

A support apparatus includes an arm assembly attached to a support assembly such that the arm assembly is positionable adjacent to an article of furniture such as a desk or work surface. A mounting device is attached to the arm assembly that is sized and configured to retain a display device. A vertically adjustable attachment mechanism attaches a first end of the counterbalance mechanism to the arm assembly or support assembly. The vertically adjustable attachment mechanism is sized and configured such that a vertical position of the first end of the counterbalance mechanism is adjustable via movement of at least one component of the vertically adjustable attachment mechanism.
