Abstract

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.

Claims (13)

1. A safety ladder system for accessing a rooftop of a building structure, comprising:

a first and second ladder side rail extending between a lower free end and an upper free end, the first and second ladder side rail diverge near the upper free end forming a gap therebetween, each ladder side rail terminating at a hand support end;

a plurality of horizontal rungs vertically disposed between the ladder side rails;

a hinged roof portion operably positioned substantially within the gap while in a default position, the hinged roof portion having parallel roof portion side rails extending between a bottom end and a top end and forming a frame having a plurality of rungs horizontally disposed therein, wherein the hinged roof portion rotates about a hinge axis positioned at the bottom end between the default position and a forward rooftop position;

a horizontal roof stop operably connected to the top end of the hinged roof portion and positioned above the gap while in the default position, the horizontal roof stop having a continuous planar exterior surface that is configured to be substantially perpendicular to the surface of the rooftop while the hinged roof portion is in the forward rooftop position, thereby providing a catch for objects on the rooftop;

wherein the hinge axis is slidable within a longitudinal path along the first and second ladder side rail, a locking means operably configured to lock a position of the hinge axis along the path in order to position the hinged roof portion at an angle which is flush with a pitch of the roof; a padding positioned on an external face the hinged roof portion and the horizontal roof stop, said padding is configured to grip a roof surface to prevent slippage.

2. The safety ladder of claim 1 , further comprising opposing first and second length adjustable tethers, each tether comprising:

a line retractor hingedly connected to a respective one of the first and second ladder side rails, the line retractor being an encasement containing a reel;

a line operably connected to the reel, wherein the line retracts and extends on the reel the operable length of the line;

a means of connecting the line end with a nearby object; and

a means for locking an operable extended length of line of the length adjustable tether.

3. The safety ladder of claim 2 , further providing a step ladder hinge bisecting the length of the ladder into two sections, wherein the safety ladder can be positioned into a step ladder configuration.

4. A safety ladder system for accessing a rooftop of a building structure, comprising: a first and second ladder side rail extending between a lower free end and an upper free end, the first and second ladder side rail diverge near the upper free end forming a gap therebetween, each ladder side rail terminating at a hand support end; a plurality of horizontal rungs vertically disposed between the ladder side rails; a hinged roof portion operably positioned substantially within the gap while in a default position, the hinged roof portion having parallel roof portion side rails extending between a bottom end and a top end and forming a frame having a plurality of rungs horizontally disposed therein, wherein the hinged roof portion rotates about a hinge axis positioned at the bottom end between the default position and a forward rooftop position; a horizontal roof stop operably connected to the top end of the hinged roof portion and positioned above the gap while in the default position, the horizontal roof stop having a continuous planar exterior surface that is configured to be substantially perpendicular to the surface of the rooftop while the hinged roof portion is in the forward rooftop position, thereby providing a catch for objects on the rooftop; wherein the hinge axis is slidable within a longitudinal path along the first and second ladder side rail, a locking means operably configured to lock a position of the hinge axis along the path in order to position the hinged rood portion at an angle which is flush with a pitch of the roof; wherein while the hinged roof portion is in the default position, the top end of the hinged roof portion terminates substantially flush with each hand support end.
