发明名称 Folding ramp
摘要 A folding ramp is provided that includes an upper ramp, a lower ramp, and at least one handle assembly for providing ease of transport of the folding ramp. The upper ramp extends between a first end and a second end, and includes an upper ramp loading track, an upper first side support, an upper second side support, and a vehicle mounting member. The lower ramp extends between a first end and a second end, and the lower ramp includes a lower ramp loading track, a lower first side support, a lower second side support, a ground engaging member, and the rotation member. The upper ramp and the lower ramp include a rotation member that extends between the upper and lower first side supports and the upper and lower second side supports to allow rotation of the lower ramp relative to the upper ramp. The lower ramp loading track includes a first side and a second side and extends from the first end of the lower ramp to the second end of the lower ramp. The lower first side support extends along the first side of the lower ramp loading track at an angle to the lower ramp loading track that is sufficient to support the lower ramp loading track. The lower second side support extends along the second side of the lower ramp loading track at an angle to the lower ramp loading track that is sufficient to support the lower ramp loading track. The ground engaging surface is provided at the second end of the lower ramp for engaging the ground.
