A foldable Ladder, comprising:
- a ladder supporting frame, which comprises:
- a back supporting frame which comprises a first and a second parallel back side leg;
- and
- a front supporting frame which comprises a first and a second parallel front side leg having a first and second inner receiving surface formed thereon respectively, wherein said first and said second front side leg are pivotally connected to said first and said second back side leg respectively so that said ladder supporting frame is capable of selectively folding between an operative mode and a standby mode, wherein in said operative mode, said front supporting frame is pivotally unfolded apart from said back supporting frame, and is inclinedly supported with respect to horizontal, and wherein in said standby mode, said front and said back supporting frame are pivotally folded to overlap with each other;
- means for retaining said ladder supporting frame in said operative mode;
- a plurality of foot supporters, each comprising a first and a second step member, wherein each step member has an outer end, and inner end and a step surface formed therebetween;
- a pivot joint pivotally connecting said inner end of said first and said second step member and said outer ends of said first and said second step member of each of said foot supporters are pivotally coupled with said first and said second back side leg and said first and said second front side leg respectively in such a manner that each of said foot supporters is capable of being folded between an unfolded position and a folded position, wherein in said folded position, said first and said second step member of each of said foot supporters are pivotally and upwardly folded toward said first and said second inner receiving surface respectively so as to reduce a distance between said first and said second front side leg, and wherein in said unfolded position, said first and said second step member are pivotally and downwardly unfolded from each other to an extent that said step surface of said first step member is aligned with said step surface of said second step member, while said step surfaces are both horizontal;
- and
- a foot supporters folding control mechanism;
- which comprises a folding controller pivotally connecting said pivot joints in such a manner that said folding controller is capable of folding said foot supporters simultaneously between said folded position and said unfolded position;
- a plurality of coupling arrangement for pivotally connecting said foot supports with said front supporting frame being supported inside a first and second front receiving cavity, wherein said first and said second front side leg have a first and a second pair of sidewalls inwardly extended from said first and said second inner receiving surface to define said first and said second front receiving cavity for receiving said coupling arrangements, and wherein said first and said second step member of each of said foot supporters have an elongated slot transversely formed on said respective outer end, for coupling with one of said coupling arrangements, each of said coupling arrangements comprising a lower mounting panel downwardly and integrally extended from said outer end of said step members, an upper mounting panel upwardly and integrally extended from said outer end of said step member, and a folding axle having two ends horizontally mounted on said pair of respective sidewalls, wherein said folding axle is arranged to penetrate said lower and said upper mounting panel through said elongated slot, such that when said foot supporters are in said unfolded position and when said ladder supporting frame is in said standby mode, said step surfaces are downwardly inclined with respect to horizontal, and when said ladder supporting frame is in said operative mode, said step surfaces are held horizontal.
