Fall arrest system
View Patent ↗A fall arrest system adapted for use in construction projects with wall studs of various spacing. The fall arrest system comprises a wall attachment bracket and a retractable harness line system, which provides extension, retraction, and storage of a harness line. The harness line is connected to a user-worn harness to protect the user from falling.
1. A fall arrest system comprising:
a first wall attachment bracket with a center wall anchor point, and further comprising a left and a right wall anchor point slideably attached to said first wall attachment bracket, each of the anchor points of the first wall attachment bracket configured to be anchored to a first wall by a bolt passing through at least one hole to allow for attachment to a first set of vertical wall studs with varying spacing between said first set of vertical wall studs, with said first wall attachment bracket configured for horizontal placement across said first set of vertical wall studs in a building, said first wall attachment bracket further comprising at least one line attachment point;
a second wall attachment bracket with a center wall anchor point, and further comprising a left and a right wall anchor point slideably attached to said second wall attachment bracket, each of the anchor points of the second wall attachment bracket configured to be anchored to a second wall by a bolt passing through at least one hole to allow for attachment to a second set of vertical wall studs with varying spacing between said second set of vertical wall studs, with said second wall attachment bracket configured for horizontal placement across said second set of vertical wall studs on the second wall positioned opposite to said first wall which said first wall attachment bracket is attached, said second wall attachment bracket further comprising at least one line attachment point;
a support line with a first end and a second end respectively configured to attach to said line attachment points on said first and second wall attachment brackets;
a harness configured for wear by a user of said system;
a harness line reel comprising a speed brake and a harness line with a first end attachable to said harness, the harness line reel configured to slideably attach to said support line, said harness line reel configured to store the harness line on said reel and feed out said harness line from said reel, and the speed brake being configured to stop said feed out of the harness line as a result of a maximum speed of said feed out being sensed;
said system configured to provide fall protection to said user wearing said harness by braking said feed out of said harness line when the maximum speed of said feed out of the harness line is reached as a result of a fall of said user.
2. The fall arrest system of claim 1 which further comprises a support line tensioner for adjusting an outfeed line tension of said support line between said wall attachment brackets.
3. The fall arrest system of claim 1 in which said support line is comprised of flat webbing.
4. The fall arrest system of claim 1 in which said first and second wall attachment brackets are generally rectangular and elongate steel bars.
5. The fall arrest system of claim 1 in which said harness comprises a belt.
6. The fall arrest system of claim 5 in which said harness further comprises leg loops.
7. The fall arrest system of claim 6 in which said harness further comprises a chest harness.
