Modular ramp system

Claim 1

A modular ramp kit having components capable of being assembled by mating first interengageable attachment members with complementarily shaped second interengageable attachment members, said components for use in conjunction with a threshold defining an offset, the kit comprising the combination of: a top plate for covering a top portion of the threshold, said top plate including one of said first interengageable attachment members, a first ramp, the first ramp defining an upper end having a height A and lower end having a lesser height B, the upper end of the first ramp including one of said second interengageable attachment members for attachment to the top plate, said lower end of said first ramp including one of said first interengageable attachment members, a second ramp, the second ramp defining an upper end having said height B and a lower end having a lesser height C, the upper end of the second ramp including one of said second interengageable attachment members for attachment to the lower end of the first ramp, said lower end of the second ramp including one of said first interengageable attachment members, a third ramp, the third ramp defining an upper end having said height C and a lower end, the upper end of the third ramp including one of said second interengageable attachment members for attachment to the lower end of the second ramp, and two skirts each adapted to be placed adjacent a respective side of at least the third ramp, each skirt defining a surface extending downwardly from the third ramp to a ground surface upon which the modular ramp is placed, each skirt and one of the ramps having mutually engageable attachment surfaces for securing each skirt to the third ramp.
