Abstract
The invention includes a work platform and support system that includes a hub and joist configuration, wherein the hubs and joists are capable of articulation, or pivoting. One method of installation allows for sections of new work platform system to be extended from an existing suspended work platform system. The system is also capable of supporting, without failure, its own weight and at least four times the maximum intended load applied to it.
Claims26
A interconnection structure for interconnection with an elongate structural member, the interconnection structure comprising:
- an element having a plurality of openings;
- an additional element having a plurality of openings located so that at least a respective one of the plurality of the openings of the element is coaxial with at least a respective one of the plurality of openings of the additional element to create at least one respective pair of coaxial openings;
- and
- a section connected between the element and the additional element;
- wherein at least one of the element and the additional element includes a support opening, the support opening disposed generally at or about a center of the respective at least one element and additional element, and the support opening is configured to receive a suspension connector, such as a chain, and permit retaining of the suspension connector at a location away from the center of the respective at least one element and additional element.

A method of using an interconnection structure, the method comprising:
- providing an interconnection structure comprising:
- an element having a plurality of openings;
- an additional element having a plurality of openings located so that at least a respective one of the plurality of the openings of the element is coaxial with at least a respective one of the plurality of openings of the additional element to create at least one respective pair of coaxial openings;
- and a section connected between the element and the additional element, and wherein at least one of the element and the additional element includes a support opening, the support opening disposed generally at or about a center of the respective at least one element and additional element;
- receiving a free end of a suspension connector by way of the at least one support opening in the element;
- retaining the end of the connector at a location away from the center of the respective at least one element and additional element.
3 more elements
An interconnection structure in combination with an auxiliary mounting bracket, the combination comprising:
- an interconnection structure for interconnection with an elongate structural member, the interconnection structure comprising:
- an element having a plurality of openings;
- an additional element having a plurality of openings located so that at least a respective one of the plurality of the openings of the element is coaxial with at least a respective one of the plurality of openings of the additional element to create at least one respective pair of coaxial openings;
- and
- a section connected between the element and the additional element;
- and
- an auxiliary suspender mounting bracket configured for connection with a suspension connector for suspension from another structure.
4 more elements
A work platform support structure comprising:
- a first interconnection structure connectable in fixed relation to a second interconnection structure using a first elongate structural member;
- a third interconnection structure connectable to a fourth interconnection structure using a second elongate structural member, the third and the fourth interconnection structures further connectable to the first and the second interconnection structures using third and fourth elongate structural members;
- wherein, when connected, the second, the third and the fourth elongate structural members, and the third and the fourth interconnection structures articulate with respect to the first and second interconnection structures and the first elongate structural member to an extended or final position;
- wherein at least one of the elongate members is connectable with at least one of the interconnection structures using a pin to provide free rotation of the at least one elongate member with respect to the at least one interconnection structure about the pin;
- wherein the free rotation is restricted by at least one of:
- i) an additional pin that is to be located proximate a perimeter of the at least one interconnection structure;
- and ii) at least a portion of a work platform when the platform is positioned with respect to the interconnection structures and the elongate members in the extended or final position;
- and
- wherein each interconnection structure includes:
- an element having a plurality of openings;
- an additional element having a plurality of openings located so that at least a respective one of the plurality of the openings of the element is coaxial with at least a respective one of the plurality of openings of the additional element to create at least one respective pair of coaxial openings;
- and a section connected between the element and the additional element;
- and
- wherein at least one of the element and the additional element includes a support opening, the support opening disposed generally at or about a center of the respective at least one element and additional element, and the support opening is configured to receive a suspension connector, such as a chain, and permit retaining of the suspension connector at a location away from the center of the respective at least one element and additional element.
