Ladder Anchor Apparatus
A ladder anchor apparatus for securing a ladder in place includes a pair of arms each having a straight portion and a hooked portion. Each of the arms has a pivot aperture. The pair of arms is configured to be selectively engageable within a pair of ladder holes of a pair of legs of a ladder. A hollow pivot rod is coupled to the pair of arms and extends through the pivot aperture of each arm. The pair of arms is pivotably coupled around the pivot rod. A mounting pin is slidingly engageable through the pivot rod and is configured to be inserted into the ground to secure the apparatus in place. An eye hook and a safety chain are coupled to a left arm of the pair of arms. The safety chain prevents the pair of arms from pivoting open when engaged with the eye hook.
LADDER STAND AND ACTIVITY RAIL ASSEMBLY
A tree stand includes an activity rail assembly rotatably attached to a chair. The activity rail assembly is rotatable among a first stowed position in which the activity rail assembly is oriented upright, a second stowed position in which the activity rail assembly is oriented downwardly, and one or more deployed positions between the first stowed position and the second stowed position. The activity rail assembly is extendable and retractable between a first position and a second position, wherein when the activity rail assembly is in the first position, a horizontal activity rail portion is closer to the chair than when the activity rail assembly is in the second position. The tree stand may further include a platform to support the chair, and, optionally, a ladder portion to support the platform.
Telescoping ladder with a cascading collapse mechanism
A telescoping ladder is provided, that includes a plurality of columns disposed in a nested arrangement for relative axial movement in a telescopic fashion between a fully-extended position and a collapsed position. The columns are connected to rungs by way of connector assemblies. Each connector assembly has a locking pin moveable between an extended position or a retracted position for extending into or retracting out of openings of adjacent columns to selectively lock or release the columns respectively. The telescoping ladder includes a plurality of actuators that permit collapsing the ladder in a sequential manner, the sequence involving collapsing the columns on a lower portion of the ladder prior to collapsing columns immediately thereabove.
Ladder
A ladder stabilizer is provided, comprising an extension bar portion, a main arm portion, a brace bar portion, teeth strips, and levers. The extension bar portion is enclosed by an outer wall surface, an inner wall surface, and two side wall surfaces, and having upper and lower end portions. The main arm portion has upper and lower end portions configured for a telescopic connection. The brace bar portion has first and second end portions, and the first end portion is connected to the side portion at a lower position, and the second end portion is connected to the extension bar portion at a middle position. The teeth strips are fixed to lower portions of the two side wall surfaces of the main arm portion. Each lever has latching and releasing ends, installed on the two side wall surfaces of the extension bar through two spring-loaded hinges.
Ladder
A rung lock assembly is provided for a ladder, and comprises rung lock portions, a pinion gear, compression springs, a rung body, a rung cover, a center bolt, a spacer, and a fastener portion. Each of the rung lock portions comprises a rod portion, a rack block fixed to the rod portion, a locking portion, a holding portion connecting the rod portion to the locking portion so that the rod portion is disposed in parallel with the locking portion and configured to be held and pulled by a user's hand, and the rung lock portions are anchored by guide plates and disposed in parallel with each other. The pinion gear is disposed between and engaging the rack blocks, so that the rung lock portions translate outwards or inwards together. The distance between the locking portion is increased in both directions simultaneously by pulling one of the holding portions.

Ladder Stabilization Apparatus and a Stable Ladder
A ladder includes a ladder stabilization apparatus which includes implements for providing sideways support, front-back support, and a bridge to rest the ladder on a structure to be climbed, such that the ladder is stable when a user climbs the ladder facing away from the structure, and the bridge allows the user to climb out of the ladder on to the structure through the bridge. The bridge also allows the user to climb on to the ladder facing from the structure, facing away from the structure, while the ladder is stable when the user climbs down while acing away from the structure.

Safety ladder
A safety ladder for accessing the rooftop of a building structure is disclosed. In a version, the safety ladder comprises a first and second side rail extending between a lower free end and an upper free end; a plurality of horizontal rungs vertically disposed between the side rails; and a hinged roof portion operably positioned between the first and second side rails near the upper free end terminating at a top end, wherein the hinged roof portion rotates about a hinge axis between a default position and a forward rooftop position.
