Ladder module and securement system

A pair of cooperating steps for use with a ladder module, wherein said pair of cooperating steps comprises:

• a. a first step, wherein said first step is pivotally mounted to said ladder module, and wherein said first step comprises:
• i. a step gear;
• ii. a step tread;
• and
• iii. a step limit adjacent said step gear;
• b. a second step, wherein said second step is pivotally mounted to said ladder module adjacent said first step, and wherein said second step comprises:
• i. a step gear, wherein said step gear of said first step directly contacts and intermeshes with said step gear of said second step such that pivoting said first step about said ladder module causes said second step to pivot a corresponding amount in the opposite direction and vice versa;
• ii. a step tread;
• and
• iii. a step limit adjacent said step gear, wherein said step limit of said first step and said step limit of said second step cooperate to limit the amount said first and said second steps rotate about said ladder module.

A ladder module comprising:

• a. a spine;
• b. a securement structure secured to said spine;
• c. a flexible member affixed to said spine, wherein said flexible member is configured to be engaged with said securement structure;
• d. a step mounting bracket base secured to said spine;
• e. a step mounting bracket bolt secured to said step mounting bracket base, wherein said step mounting bracket bolt passes through an aperture formed in said spine;
• f. a tree bracket secured to said spine, wherein said step mounting bracket bolt passes through an aperture formed in said tree bracket, and wherein said tree bracket includes a plurality of tree engagement members;
• g. a nut, wherein said nut engages said step mounting bracket bolt;
• h. a first step, wherein said first step is pivotally mounted to said step mounting bracket base, and wherein said first step comprises:
• i. a step gear;
• ii. a step tread;
• and
• iii. a step limit adjacent said step gear;
• i. a second step, wherein said second step is pivotally mounted to said step mounting bracket base adjacent said first step, and wherein said second step comprises:
• i. a step gear, wherein said step gear of said first step directly contacts and intermeshes with said step gear of said second step such that pivoting said first step with respect to said spine causes said second step to pivot a corresponding amount in the opposite direction and vice versa;
• ii. a step tread;
• and
• iii. a step limit adjacent said step gear, wherein said step limit of said first step and said step limit of said second step cooperate to limit the amount said first and said second steps rotate with respect to said spine;
• j. a top cam pivotally mounted to said spine, wherein said top cam includes a plurality of cleats on a bottom surface, wherein a periphery of said bottom surface is generally curved, and wherein a portion of the periphery of said top cam is generally flat adjacent said bottom surface;
• k. a bottom cam pivotally mounted to said spine, wherein said bottom cam includes a plurality of cleats on its top surface, wherein the distance between the respective axes of rotation of said top cam and said bottom cam is between 0.15 and 6 inches, wherein the periphery of said top surface is generally curved, and wherein a portion of the periphery of said bottom cam is generally flat adjacent said top surface;
• l. a flexible member, wherein a first end of said flexible member is configured to be secured to said spine, and wherein said flexible member is configured to be engaged with said top and bottom cam such that when said flexible member is positioned between said top and bottom cam and said portion of the periphery of said top cam and said portion of the periphery of said bottom cam are parallel with respect to one another, said top cam and said bottom cam pinch said flexible member such that said top and bottom cams cannot counter rotate past one another;
• and
• m. at least one step pivotally engaged with said spine.
