Ramp component system

A ramp component, comprising:

• a sill nosing that is configured to be coupled with a bottom surface of a door opening, the sill nosing comprising:
• a horizontal member that is configured to be seated atop a lower horizontal surface of the door opening;
• and
• a vertical member extending downward from the horizontal member at a substantially orthogonal angle, the vertical member being configured to be positioned against a lateral surface below the door opening, the vertical member comprising an upward-facing hook feature that extends along at least part of a width of the sill nosing, wherein:
• the upward-facing hook feature and a lateral surface of the vertical member define a channel that has an open top;
• a vertical distance from a top of the upward-facing hook feature and a top surface of the horizontal member is greater than an opening width of the upward-facing hook feature;
• and
• the horizontal member terminates at a junction with the vertical member such that the upward-facing hook feature extends laterally beyond distal end of the horizontal member and such that the open top of the channel remains uncovered by the horizontal member.

A ramp system, comprising:

• a first ramp component comprising:
• one or more ramp planks, each of the one or more ramp planks comprising an upper end and a lower end, and each of the one or more ramp planks comprises an upper surface and a lower surface that extend between the upper end and the lower end;
• and
• a protrusion that extends from the upper end at a downward angle relative to the upper surface of the one or more ramp planks;
• and
• a second ramp component comprising:
• a sill nosing that is configured to be coupled with a bottom surface of a door opening, the sill nosing comprising:
• a horizontal member that is configured to be seated atop the bottom surface of the door opening;
• and
• a vertical member extending downward from the horizontal member, the vertical member comprising an upward-facing hook feature that extends along at least part of a width of the sill nosing, wherein:
• the upward-facing hook feature and a lateral surface of the vertical member define a channel that has an open top;
• the horizontal member terminates at a junction with the vertical member such that the upward-facing hook feature extends laterally beyond distal end of the horizontal member and such that the open top of the channel remains uncovered by the horizontal member;
• and
• the protrusion is configured to engage with the channel to rotatably couple the first ramp component and the second ramp component such that an angle of the one or more ramp planks is adjustable relative to the sill nosing when the protrusion is engaged with the channel.
