Patent ID: 7080959

Claim:
A shoring device, comprising: A) a scaffolding assembly including at least one tubular vertical member with an open upper end; B) an accessory assembly having an elongated substantially cylindrical body with first and second ends, said body including a threaded portion having a first outer diameter and a first inner diameter adjacent to said first end and a saddle portion having a second inner diameter slightly larger than said first outer diameter to permit said threaded portion to partially penetrate inside said saddle portion to define an inward step that rests on said upper end and said saddle portion being adjacent to said second end, said threaded portion receiving said vertical member there through and, said saddle portion partially receiving a portion of said vertical member adjacent to said upper end, and said threaded portion including at least one longitudinally extending slot; C) an elongated shoring member telescopically and partially receivable through said threaded and saddle portions, said shoring member including at least one cooperating radial through hole that is selectively aligned with at least one of said slots; D) a ring assembly having an internal thread mating with said threaded portion and selectably positioned therealong; and E) a locking pin having cooperative dimensions to lockingly engage with at least one of said slots and one of said at least one radial through hole, and resting on said ring assembly that in turn transmits the load through said threaded portion to said vertical member, so that in cooperation with said ring assembly permits a user to adjust the effective length of said scaffold and shoring assemblies.
