Abstract
A fall protection system having two telescoping supports positioned at either end of a job location and having a crossbar extending there between that allow a user to work in an elevated position while also providing a tethering point to protect against falls. The supports may be coupled to a pair of conventional ladders that support a walk board, or the supports may directly support a walk board extending between the two supports. The two supports retain and securely attach to a horizontal support beam that is the anchoring location for a fall protection harness. A user may then use the walk board to perform installations or repairs above the minimum height necessary for fall protection and be secured against a fall by attaching via a harness and strap to the cross-bar.
Description
- The present application is a continuation-in-part of U.S. application Ser. No. 14/257,186, filed on Apr. 21, 2014.
- 1. Field of the Invention
- The present invention relates to fall protection systems and, more particularly, to a system for securely supporting a user engaged in building repairs and renovations.
- 2. Description of the Related Art
- Falls are the leading cause of worker injuries and fatalities in the construction industry in the United States. Each year, between 150 and 200 workers are killed and more than 100,000 are injured as a result of falls at construction sites, despite numerous federal regulations requiring the use of fall protection systems. For example, the Occupational Safety and Health Administration (OSHA) requires that personal fall arrest systems will, when stopping a fall, limit maximum arresting forces, be rigged such that an employee can neither free fall more than six feet nor contact any lower level, bring an employee to a complete stop and limit maximum deceleration distance to 3 ½ feet, and have sufficient strength to withstand twice the potential impact energy of a worker free falling a distance of 6 feet or the free fall distance permitted by the system. Many other rules and regulations govern worker safety and must be complied with to reduce worker injuries.
- One approach to providing protection when work is being performed on the side of a building, such as during window installation or repair, is to remove the roof ridge cap or sheathing and install an anchorage to the truss or rafter structure underneath as roof sheathing does not provide enough support. This process necessary compromises roof integrity and can lead to future problems, such as leaking roofs and lost roof tiles. In addition, this approach requires that contractors have access to and climb onto the roof to install and remove the anchor system, which is time consuming and may require additional equipment not necessary for the particular job and location.
- The present invention comprises a fall protection system that is easily installed and does not involve retrofitting an anchorage to the roof or otherwise compromising roof integrity. Instead, a user deploys two vertical supports positioned at either end of a job location. The two vertical supports, which may be telescoping, are interconnected to a horizontal support beam that is used as the anchoring location for a fall protection harness or arrest system. The two vertical supports may be interconnected to two conventional ladders, which may additionally support a conventional walk board via ladder jacks. Alternatively, the two vertical supports may support a walk board affixed to the supports by moveable brackets. A user may then perform installations or repair while standing on the walk board and secured against a fall by attaching to the horizontal support beam. In addition, the horizontal support beam may be used to support a hoist with or without the walk board in position. Thus, the present invention avoids the need for extensive site installation and may be used with conventional ladder work system to provide sufficient fall protection and satisfy government workplace regulations.
- The present invention will be more fully understood and appreciated by reading the following Detailed Description in conjunction with the accompanying drawings, in which:

Alternatively,lower member 22 andupper member 24 can be integrally formed as a single unit, pivotally attached to each other, or interconnected via fasteners.Lower member 22 preferably comprises a tubular structure that housesupper member 24 is various states between a retracted position and an expended position. Although aretractable pin 26 associated withlower member 22 may be used with a corresponding series ofholes 28 inupper member 24 for interlockinglower member 22 andupper member 24 in a fixed position relative to each other, it should be recognized by those of skill in the art that other known mechanisms for securing telescoping elements in place may be used. The composition and dimension of telescoping supports 12 and 14 andhorizontal support 16 are preferably selected to comply with current government regulations, such as the fall protection standards of the Occupational Safety and Health Administration (OSHA) that currently require that anchorages for personal fall arrest systems satisfy 5,000 pound tensile load tests. - As seen in

In the event that the user slips off of walk-board 54,horizontal support 16 will prevent user from falling to the ground. Alternatively,horizontal support 16 could additionally be positioned to act as a guard rail in lieu of or in addition to performing the role a fall arrest anchor location. - In addition to using
support 16 as the tethering point for a personal arrest system, the present invention may be used as a hoist to lift virtually any heavy item that falls within the safety factors of the system.
