Abstract:
1. A bracket in combination with a ladder, the combination is for mounting to a top edge of a trench box wall, the ladder comprising multiple rungs connecting between a pair of ladder stiles; the bracket comprising: a) a frame having an upper cross beam, a lower cross beam parallel to said upper cross beam, a first side beam and a second side beam parallel to said first side beam, wherein a lower end of said first side beam is connected directly to a first end of said lower cross beam and a lower end of said second side beam is connected directly to a second end of said lower cross beam, and an upper end of said first side beam and an upper end of said second side beam are each respectively connected directly to said upper cross beam at separate locations between a first end and a second end of said upper cross member, such that a first portion of said upper cross member extends beyond said upper end of said first side beam in one direction and a second portion of said upper cross member extends beyond said upper end of said second side beam in an opposite direction; b) a first arm and a second arm, said first arm having a first end connected to said first end of said upper cross member and said second arm having a first end connected to said second end of said upper cross member, wherein said first arm and said second arm each have a respective second end extending in a perpendicular direction away from said upper cross member; c) a lip extending from said second end of said first arm to said second end of said second arm and disposed parallel to and spaced from said frame; d) a first pair of ladder stop members, a first member of said first pair of stop members connected directly to said first end of said upper cross member, a second member of said first pair of stop members connected directly to said second end of said upper cross member, wherein said first pair of stop members extend in a perpendicular direction away from said frame in a direction opposite said first arm and said second arm, wherein said first pair of ladder stop members are spaced a first distance apart; and e) a second pair of ladder stop members, a first member of said second pair of stop members connected directly to a lower end of said first side beam, a second member of said second pair of stop members connected directly to a lower end of said second side beam, wherein said second pair of stop members extend in a perpendicular direction away from said frame in a direction opposite said first arm and said second arm, each of said second pair of ladder stop members disposed within said first distance relative to a longitudinal axis of said upper cross member, wherein said second pair of ladder stop members are spaced a second distance apart, and said first distance is greater than said second distance; f) wherein all of said first member of said first pair of ladder stop members is co-axial with said first arm and all of said second member of said first pair of ladder stop members is co-axial with said second arm.
