Abstract
A system of increased safety when performing work using a ladder is described. The system includes a ladder bracket for temporarily attachment of a ladder to a structure to stabilize or secure the ladder. The bracket is easy to install and acts to limit or prevent slippage of the ladder laterally or away from the structure and generally promotes a greater margin of safety. In addition, the system includes a bracket for temporarily, yet securely, attaching a safety railing to a ladder. A guardrail carriage for securing a person to a rail via a tether is further provided.
Claims3
A ladder safety system comprising:
- a) a rail jack comprising:
- i) an upper rung bracket and a lower rung bracket each adapted to fit over a rung of a ladder;
- ii) a vertical post rigidly connected to both the upper rung bracket and the lower rung bracket such that the rung brackets are positioned and spaced to simultaneously fit over rungs of a ladder;
- and
- iii) a rail support member attached directly to said vertical post;
- and,
- b) a ladder security bracket consisting of:
- i) a transverse member having a first end and an opposed second end;
- i) a first lateral stop member having a first end and an opposed second end and connected at said first end to said transverse member first end;
- iii) a second lateral stop member, of identical length to said first lateral stop member, having a first end and an opposed second end and connected at said first end to said transverse member second end wherein said second lateral stop member is parallel to said first lateral stop member and extends in the same direction as said first lateral stop member from said transverse member;
- iv) a first mounting member having one or more apertures therein connected to said first lateral stop member second end wherein said first mounting member is parallel to said transverse member and extends in an opposite direction as said transverse member from said first lateral stop member;
- and
- v) a second mounting member having one or more apertures therein connected to said second lateral stop member second end wherein said second mounting member is parallel to said transverse member and to said first mounting member and extends in an opposite direction as said transverse member from said second lateral stop member;
- wherein said ladder security bracket can be placed over at least one rail of a ladder when the ladder is leaning against a structure such that said mounting members contact the structure, at least one rail of the ladder is positioned between the lateral stop members, and at least one rail of the ladder is positioned between the structure and the transverse member.
The ladder safety system of claim one further comprising a guardrail carriage for providing a rolling restraint point connected to a rail wherein said guardrail carriage comprises:
- a) a frame comprising
- i) a top portion comprising at least two rollers disposed,
- ii) two side portions rigidly affixed to and angularly configured to the top portion, to form a substantially inverted U-shape each comprising at least two rollers disposed on the side portions so as to engage and roll along the length of the side surface of the rail,
- b) a securing means for securing the frame to the rail comprising a locking pin that removeably connects the two side portions of said frame at a position beneath the rail;
- and
- c) a means for securely attaching one end of a safety tether.
The ladder safety system of claim one further comprising a rail end stop wherein said rail end stop comprises:
- a) a rail sleeve sized to slideably engage a rail;
- and,
- b) a rail bar rigidly affixed to said rail sleeve such that the rail bar is perpendicular to the rail length when the rail sleeve is mounted on the rail.
