Safety ladder

A safety ladder suitable to be mounted between a support surface and a ground surface, comprising:

• two support assemblies spaced apart from each other in a left-right direction, each of said support assemblies including a first support rod and a second support rod spaced apart from each other in a front-rear direction transverse to the left-right direction, each of said first and second support rods having an upper end, a lower end opposite to said upper end, and a plurality of spaced-apart pivot connecting portions disposed between said upper end and said lower end;
• and
• a plurality of parallel step members pivotally connected between said support assemblies;
• wherein said upper ends of said first support rods of said support assemblies are configured to be pivotally connected to the support surface so as to be movable up and down relative to the support surface;
• wherein said safety ladder is movable between a use position and a storage position;
• wherein, when said safety ladder is moved to said use position, said first and second support rods of said support assemblies stand oblique relative to the support surface and the ground surface, said lower ends of said first and second support rods of said support assemblies are adapted to simultaneously contact the ground surface, and said first and second support rods are parallel to and spaced apart from each other;
• wherein, when said safety ladder is moved to said storage position, said first and second support rods of said support assemblies stand substantially perpendicular relative to the ground surface(2), and are parallel to and spaced apart from each other;
• and
• wherein, when said safety ladder is in said use position, said first and second support rods of said support assemblies are configured to form an included angle with the ground surface, and said step members are configured to be disposed substantially parallel to the ground surface even during a change in said included angle.
