Abstract
Abstract An adjustable shoring system includes base frames, extension frames which are vertically adjustable with respect to the base frames in a series of incremental steps, and gooser braces extending between headers on the extension frames and on the opposite base frames. The extension and base frames are each provided with two vertically spaced headers; and the headers on the extension frames are spaced apart a distance equal to one step of adjustment while the headers on the base frames are spaced apart a distance equal to two steps, as the result of which gooser braces of the same length can be used for each of a series of four steps of adjustment.

Claim 1
Independent Claim
260 words
In an adjustable shoring system or the like including a pair of facing base frames and a pair of facing extension frames, with one extension frame being supported on each base frame, the improvement wherein: at least one of the extension frames is vertically adjustable with respect to its associated base frame; and there is support means interposed between said adjustable extension frame and said associated base frame so that said adjustable extension frame can be supported on said associated base frame in any of a series of at least four equally vertically spaced steps; and said adjustable extension frame and the opposite base frame are each provided with a set of two vertically spaced attachment point means, the attachment point means on one of said frames being vertically spaced apart a distance equal to the distance moved by said adjustable extension frame in one step of adjustment and the attachment point means on the other of said frames being vertically spaced apart a distance equal to the distance moved by said adjustable extension frame in two steps of adjustment; and there is a gooser brace of fixed length having opposite ends removably attachable to said attachment point means, the length of said gooser brace being such that when the said adjustable extension frame is in the lowermost of its four positions of adjustment one end thereof can be attached to the lowermost attachment point means of said opposite base frame and the other end thereof can be attached to the uppermost attachment point means of said adjustable extension frame.
Claim 2
Dependent Claim
260 words
In an adjustable shoring system or the like including a pair of facing base frames and a pair of facing extension frames, with one extension frame being supported on each base frame, the improvement wherein: at least one of the extension frames is vertically adjustable with respect to its associated base frame; and there is support means interposed between said adjustable extension frame and said associated base frame so that said adjustable extension frame can be supported on said associated base frame in any of a series of at least four equally vertically spaced steps; and said adjustable extension frame and the opposite base frame are each provided with a set of two vertically spaced attachment point means, the attachment point means on one of said frames being vertically spaced apart a distance equal to the distance moved by said adjustable extension frame in one step of adjustment and the attachment point means on the other of said frames being vertically spaced apart a distance equal to the distance moved by said adjustable extension frame in two steps of adjustment; and there is a gooser brace of fixed length having opposite ends removably attachable to said attachment point means, the length of said gooser brace being such that when the said adjustable extension frame is in the lowermost of its four positions of adjustment one end thereof can be attached to the lowermost attachment point means of said opposite base frame and the other end thereof can be attached to the uppermost attachment point means of said adjustable extension frame.
Claim 3
Dependent Claim
38 words
The system of claim 1 wherEin said adjustable extension frame and said opposite base frame each have opposite, parallel vertical legs; and all of said attachment point means comprise horizontal headers secured to and extending between said legs.
Claim 4
Dependent Claim
263 words
In an adjustable shoring system or the like including a pair of facing base frames and a pair of facing extension frames mounted on respective base frames, the improvement wherein: there are support means interposed between the base and extension frames so that each extension frame can be mounted on its associated base frame in any of a series of at least four equally vertically spaced steps; and each of the base and extension frames is provided with a set of two vertically spaced attachment point means; and, with respect to each extension frame and the opposite base frame, the vertical spacing between the attachment point means on one of said frames is equal to the distance moved by the extension frame in one step of adjustment and the vertical spacing between the attachment point means of the other frame is equal to the distance moved by the extension frame in two steps of adjustment; and there are at least two gooser braces of fixed length having opposite ends which are adapted to be removably connected to the attachment point means, there being one gooser brace connected to and extending between one attachment point means of each extension frame and one attachment point means of the opposite base frame, the length of the gooser braces being such that when the extension frame is in the lowermost of its four positions of adjustment the gooser brace is adapted to be connected to and extend between the lower attachment point means of the base frame and the upper attachment point means of the extension frame.

Claim 6
Dependent Claim
35 words
The system of claim 3 wherein each of the extension and base frames has opposite, parallel vertical legs; and all of the attachment point means comprise horizontal headers secured to and extending between said legs.
