As such, the ladder can effectively prevent children from unlocking the protective door and accessing the pool.

Abstract: A collapsible ladder (10) is disclosed having rungs secured to telescopically collapsible stile sections and at least one stabiliser bar secured to the foot of the ladder, the (or each) stabiliser bar (12a, 12b) being displaceable between a storage position in which the bar lies, at least predominantly, between the two stiles and a deployed position in which the bar widens the footprint of the ladder to improve the lateral stability of the ladder. A rod (20) is connected to extend downwardly from the uppermost stile section of the ladder and a catch mechanism (30) is provided at the foot of the ladder to engage the lower end of the rod to prevent the ladder from being extended. The catch mechanism (30) is operable by the (or a) stabiliser bar to release the rod and permit the ladder to be extended only when the stabiliser bar is in the deployed position.

Abstract: Ladder modules are provided in manageable length sections. The first section is secured at the top with a multi-hole horizontal mounting bar that is secured by a ratchet strap with hooks. The bottom of the first section rests firmly on the ground with a cleat at the bottom to secure the ladder section and prevent shifting. The second section contains a ball on the bottom of the structure that is mounted onto the first section by placing the ball into the receiving end of the first section, which allows the second section to pivot 360 degrees and lean and tilt fore and aft. This section is also secured to the tree with a ratchet strap and hooks, and is safe to climb to the next section after tightening the ratchet strap. Additional sections can be added in the same manner as the second section to pivot and level as needed.
