Abstract:
1. A leg assembly in combination with a ladder configured to support a user, the leg assembly in combination with the ladder comprising: a leg having a first end and a second opposing end, said first end being configured to engage a floor, said leg formed of an elastomer material extending over an entire major longitudinal length between said first and second ends to inhibit, when said first end engages the floor, the ladder from rolling; a pusher assembly coupled to said second end of said leg, said pusher assembly including a threaded bore; a connecting rod extending along a major longitudinal axis of the leg assembly which is parallel to the major longitudinal length of said leg, the connecting rod having a threaded first end in mesh with said threaded bore of said pusher assembly, said connecting rod having a second end; an outer tube housing said leg and restraining relative rotation therein, said tube further housing said pusher assembly and said connecting rod; a cap assembly coupled to said connecting rod at said second end of said connecting rod in a manner configured to (i) fix a longitudinal position of said connecting rod relative to said outer tube, and (ii) allow rotation of said connecting rod about said axis, said cap assembly configured to be rotated by a user to cause rotation of said threaded first end of said connecting rod in mesh with said threaded bore of said pusher assembly to axially move both of said pusher assembly and said leg along said axis relative to said outer tube while said cap assembly remains axially fixed along said axis relative to said outer tube, and wherein, when in use, rotation of said connecting rod in a first direction extends said leg from said outer tube and rotation of said connecting rod in a second direction opposite the first direction retracts said leg into said outer tube, wherein said extension or retraction of said leg adjusts a length that said leg extends from said outer tube to allow for wear in the leg or to accommodate uneven or irregular floor surfaces.
