Escape ladder

An escape ladder for attachment to a dwelling wall at a window to provide egress from the dwelling, the escape ladder comprising:

• a ladder assembly having a pair of straps and a series of rungs extending between the straps;
• a hook assembly connected to the ladder assembly, the hook assembly having a pair of laterally spaced clamps, each of the clamps comprising an upper hook and a lower hook, the upper and lower hooks pivotally connected by a hinge, the hinge comprising a generally U-shaped channel having a hinge axis, the hinge receiving first ends of the upper and lower hooks within the channel to limit the relative rotation of the upper and lower hooks to a maximum degree corresponding to a deployed configuration of the hook assembly, the lower hook being disposed in a first plane defined by the shape of the lower hook and the upper hook being disposed in a second plane defined by the shape of the upper hook;
• and
• the second plane being non-parallel to the first plane, wherein the upper and lower hooks rotate towards each other and overlap when the hook assembly is placed in an un-deployed configuration.

An escape ladder for attachment to a dwelling wall at a window to provide egress from the dwelling, the escape ladder comprising:

• a ladder assembly having a pair of supports and a series of rungs extending between the supports;
• a hook assembly connected to the ladder assembly, the hook assembly having a pair of laterally spaced clamps, each of the clamps comprising an upper hook and a lower hook, the upper and lower hooks pivotally connected by a hinge for rotation towards each other to form an un-deployed configuration where the upper and lower hooks overlap;
• the hinge comprising an elongate channel defining a hinge axis, the hinge receiving first ends of the upper and lower hooks within the channel;
• the shape of the lower hook defining a first plane and the shape of the upper hook defining a second plane non-parallel to the first plane;
• the hinge axis being non-parallel to both the first and second planes.
