Filed:

Oct 3, 1975

Appl. No.:

5/619529

Inventors:

Ronald G. Morris - Beaver Falls PA

Assignee:

Beaver-Advance Corporation - Ellwood City PA

International Classification:

E04H 1218

US Classification:

52122

Abstract:

A skeletonized, adjustable, high-rise scaffold assembly employs stacked sections, each made-up of a pair of opposed end frames or panels. The end frames of cooperating upper and lower sections are each provided with a pair of main or outer, supporting side legs and retained latching pin means for vertically adjustably connecting the sections together. Side legs of each end frame have a pin connector extending inwardly within a plane of the frame to removably receive ends of cross brace members that are mounted to extend from an end frame of one section diagonally across in a connected relation with an opposed end frame of the other section. The cross brace members have spaced-apart latching hole portions at at least one of their ends to enable a selection of a proper hole portion that is related to or compatible with an up or down adjustment of the frames of an upper section with respect to frames of a cooperating lower section. In one embodiment, the section bracing connections are made between inner or secondary leg members of the opposed frames, and in another embodiment, the connections are between main or outer leg members of the opposed frames.

Abstract:

A shoring or scaffold for construction, maintenance and other work, using stacked scaffold sections of a demountable type and having a heighth adjusting construction is provided. Each section has a pair of spaced-apart end frames that are demountably cross-connected with respect to each other and the end frames of upper and lower sections have a telescopic adjustable relation to meet heighth requirements. To provide strength and support rigidity, dual-tire bracing members are utilized to extend from the end frame of a lower section across and in an interconnecting relation with an opposed end frame of an upper section. A simple adjustment of the bracing members in conformance with vertical adjustments made between upper and lower sections is accomplished by utilizing members that at one end have a gooser pivot mounting on a horizontally extending connecting member of a frame of one section and that at the other end have a latching arm which is provided with a group of spaced-apart latching hole portions whose spacing is proportioned to vertical adjustment positions between the upper and lower sections. The latching hole portions are adapted to selectively detachably latch with a single latching pin means which is carried in a protected relation on an inwardly offset, short length or secondary leg member of the opposed frame of the other section. This enables the use of a single brace member for different heighth adjustments of stacked sections.
