The present invention is a safety device that secures a ladder to a rooftop, preventing the ladder from dislodging off the rooftop. The ladder lock apparatus includes a ladder lock body, a locking pin, and at least one anchor fastener. The ladder lock body contains an anchor end, a ladder receiving end, an anchor plate, a ladder receiver, at least one locking aperture, and at least one anchor aperture. The anchor plate is positioned opposite to the ladder receiver along the anchor plate. The locking aperture traverses through the ladder receiver. The locking pin is removably positioned within the locking aperture. The at least one anchor aperture is distributed about the anchor plate. Each of the at least one anchor fastener is removably positioned within one of the at least one anchor aperture. The anchor plate is removably attached to the rooftop through the at least one anchor fastener.

A slidable ladder device is configured to be sleeved on and slidable along a crossbar, and includes two support rods and a plurality of steps connected between the support rods. At least one fixing unit is connected to an end portion of one of the support rods, and includes a base member having a main portion, a connecting portion and an extension portion cooperatively defining an insertion space for insertion of the crossbar therethrough. A switchable member is pivotally connected to the connecting portion, and is rotatable relative to the connecting portion between closed and open positions, in which the switchable member closes and opens an opening of the insertion space, respectively.

A simply smart ladder clamp includes a first generally Sigma-shaped body portion having a first downwardly extending arm and a second downwardly extending arm which together subtend and define an intermediate element with an inner laterally extending flat surface and a recess adjacent the first downwardly extending arm. A clamping member captures a flat portion of the gutter between the flat portion and an inner surface of the first downwardly extending arm to mount the simply smart ladder clamp to the gutter. Preferably two simply smart ladder clamps are used, positioned inside the legs of a ladder to prevent movement of the ladder relative to the gutter.

A ladder safety stabilizer is a telescopically adjustable device that attaches to the rung of a ladder on one end and to the building that the ladder is leaning against at the other end to prevent the feet of the ladder from sliding while a user is climbing, and to provide a second stabilization point in addition to the feet of the ladder to provide greater ladder stability, increased safety, and reduced accident risk.

A ladder landing support apparatus includes an angled base plate including a first portion and a second portion defining an angle with the first portion, and a ladder engaging part extending upwardly from a top side of the first portion, the ladder engaging part being engageable with feet of a ladder so as to substantially prevent slippage thereof in a direction parallel to the first portion, wherein the angled base plate is angled to engage a ledge such that the first portion is engageable with a top horizontal surface of the ledge and the second portion is engageable with a front vertical surface of the ledge.

A ladder is provided comprising a first pair of spaced apart rails and a plurality of rungs extending between and coupled to the first pair of spaced apart rails. A pair of hooks are located such that each hook is positioned adjacent and upper end of an associated rail. A securing apparatus is coupled adjacent the upper end of the first pair of spaced apart rails. The securing apparatus includes a pair of spaced apart engaging members and may include a cross-member coupled therebetween. Each of the engagement members is pivotal with respect to an associated rail of the first pair of spaced apart rails. In one embodiment, the securing apparatus lacks any biasing members (e.g., springs or actuators) or locking members. The engagement members and hooks cooperatively encircle and overhead, generally horizontal support member to support and secure the ladder in a desired position.

It is disclosed a nivellation device making it possible to place ladders horizontally on sloping ground. Such a device comprises a foundation (1) onto which there is secured/placed an elevated area (2), said elevated area (2) functioning as a fulcrum/see-sawing point for a plate (3) onto which plate (3) there may be placed or secured a ladder (I), and said plate 3 being equipped with securing devices (4) that may stay the position of the plate (3) in relation to the foundation (1). Additionally it is disclosed a tightening device for a wire that may be used for securing the nivellation device in a correct horizontal orientation and a device for ensuring that the ladder is not displaced in relation to a house wall.

A ladder weight having an elongated weighted member with a pair of parallel spaced arms attached to and extending upwardly from the elongated weighted member. The pair of arms terminate in a hooked portion adapted to receive a rung of the ladder. The arms and the hook portion have holes that are aligned to receive a bolt to secure the ladder weight to the rung of the ladder.

A ladder tree stand raising apparatus for raising a ladder tree stand into position adjacent to a tree. The apparatus comprising an elongated member, a first lateral member, and a second lateral member. The elongated member having a first end and a second end. The first end of the elongated member is connectable to the tree. The first lateral member is connected to the second end of the elongated member. The second lateral member is connected to the elongated member and spaced a distance from the first lateral member. The second lateral member has at least one arm having a substantially U-shaped configuration. The at least one arm is engageable with a rung of the ladder tree stand. An open end of the at least one arm extends away from the second lateral member.

The present invention discloses a rooftop fall protection system including a plurality of mast assemblies and at least one ladder assembly removably engaged with the mast assembly. The ladder facilitates the elevation of a human to an elevated surface on a structure. Each of the ladder assemblies and mast assemblies are coupled to at least one cross-member positioned at a height above the perimeter of the elevated surface. The cross-member protects the human from falling from the elevated surface of the structure.
