| 182178100 | STACKABLE | 6 |
| 20090301815 | Modular scaffold system - A modified scaffold support post includes areas of reduced diameter, intermediate the length of the support post, having connecting rosettes secured to these reduced diameter areas. Preferably the areas of reduced diameter correspond to diameter of support tubes used as uprights in scaffold frames in North America (approximately 1.69 inches in outer diameter). Preferably the areas of reduced diameter are formed by swaging a tube of a larger diameter, typically approximately 1.90 inches. The modified support post is advantageously used with scaffold frames with connecting rosettes appropriately positioned on the uprights of the scaffold frames. | 12-10-2009 |
| 182178200 | Ladder section | 2 |
| 20160017657 | SEGMENTED COLLAPSIBLE LADDER - A ladder assembly includes a plurality of interconnected ladder segments. Each ladder segment comprises two opposing rails and rungs that are pivotably mounted to the rails to allow each ladder segment to be collapsed by pivoting the rungs in a folding direction relative to the rails and moving opposing rails closer to each other. Each ladder segment may be erected by pivoting the rungs in an opposite unfolding direction relative to the rails. Ladder segments further comprise top and bottom rail connectors allowing interconnection of the top of that ladder segment to the bottom of another of the ladder segments. The top and bottom rail connectors are keyed, so that first and second connected ones of said plurality of ladder segments will be oriented with the unfolding direction of their rungs opposite to each other. | 01-21-2016 |
| 182178400 | Overlapping sections | 1 |
| 20100025154 | MODULAR LADDER - A modular ladder system is provided, wherein segments may be joined without limit to form a ladder of any desired length. | 02-04-2010 |
| 182178500 | Male and female connecting means | 3 |
| 20090236181 | STACKABLE SCAFFOLDING FRAMES - A scaffolding frame comprises a pair of spaced apart elongated vertical members having respective top and bottom ends thereof and at least one elongated horizontal member mounted at each longitudinal end thereof to a respective one of the vertical members. Each vertical member defines a respective opposite lateral side of the frame. The horizontal member comprises a depressed portion near each longitudinal end thereof. When a first such frame is stacked onto a second such frame, one depressed portion and one vertical member of the first frame respectively engage one vertical member and one depressed portion of the second frame. | 09-24-2009 |
| 20120228060 | HIGH CAPACITY VERTICAL MEMBER FOR USE WITH MODULAR SCAFFOLDING - A vertical member of a modular scaffolding system includes a securing rosette provided in an upper section having a reduced diameter to provide a pre-determined modular connection. The vertical member includes an elongate intermediate section forming the majority of the vertical member of a first diameter greater than the reduced diameter. The intermediate section at a lower edge includes an integral spigot of the reduced diameter. A reinforcing sleeve is fixedly secured to the upper section above the rosette and forms a spigot receiving socket. The vertical member has higher capacity due to the larger diameter intermediate section while maintaining modularity of the scaffolding system. | 09-13-2012 |
| 20150014096 | HIGH CAPACITY VERTICAL MEMBER FOR USE WITH MODULAR SCAFFOLDING - A vertical member of a modular scaffolding system includes a securing rosette provided in an upper section having a reduced diameter to provide a pre-determined modular connection. The vertical member includes an elongate intermediate section forming the majority of the vertical member of a first diameter greater than the reduced diameter. The intermediate section at a lower edge includes an integral spigot of the reduced diameter. A reinforcing sleeve is fixedly secured to the upper section above the rosette and forms a spigot receiving socket. The vertical member has higher capacity due to the larger diameter intermediate section while maintaining modularity of the scaffolding system. | 01-15-2015 |
