This non-provisional patent application is based on provisional patent application Ser. No. 61/931,181 filed on Jan. 24, 2014.
FIELD OF THE INVENTIONThe present invention relates to safety screens for use during building construction and, more particularly, safety screens for preventing construction workers from falling from edges of building precipices.
DISCUSSION OF THE RELATED ARTCurrent Occupational Safety and Health Administration (OSHA) safety standards require temporary installment of protective rails at building construction sites for preventing construction workers from falling from edges of building precipices, including windows, balconies, stair wells and elevator shafts. Generally, an arrangement of two-by-four boards is nailed and/or fastened to the deck (e.g., slab) to support a top horizontal rail at forty-two inches high in order to at least partially obstruct the opening in order to prevent construction workers from accidentally falling. A significant disadvantage of this well known practice is the limited coverage of the opening, and limited protection provided by the 42 inch high protective rail. Consequently, this widely used method minimizes accidental falls but does not prevent them.
While other safety practices utilizing restraints for preventing accidental falls have been developed, they have largely remained unused in the construction industry for various practical reasons. One example of an attempt to address the problems associated with presently used 42″ protective rails can be found in U.S. Pat. No. 6,758,306, which discloses a construction safety screen that is securable about worker-area precipices. However, the '306 construction safety screen requires a variety of different fasteners, which are not adapted for use with commonly used tools and can be costly and complicated to install. Moreover, the '306 construction safety screen includes a net border that is size-specific and limits flexible use with different sized openings.
Accordingly, there remains a need for a construction safety screen system that is easy to install and which provides complete floor to ceiling coverage for preventing accidental falls.
OBJECTS AND ADVANTAGES OF THE INVENTIONConsidering the foregoing, it is a primary object of the present invention to provide a construction safety screen system for preventing accidental falls from edges of building precipices.
It is a further object of the present invention to provide a construction safety screen system that is adjustable for accommodating different sized openings.
It is a further object of the present invention to provide a construction safety screen system that is re-usable.
It is a further object of the present invention to provide a construction safety screen system that is lightweight and durable.
It yet a further object of the present invention to provide a construction safety screen system that can be quickly and easily installed and removed using standard tools.
These and other objects and advantages of the present invention are more readily apparent with reference to the detailed description and accompanying drawings.
SUMMARY OF THE INVENTIONThe present invention is directed to a construction safety screen system including a flexible net member sized to cover an opening of a building, a plurality of straps attached to the flexible net member, and a plurality of snap hooks each being securable to the distal end of one of the plurality of straps and to one of a plurality of fasteners attached to the concrete building structure surrounding the opening.
For a fuller understanding of the nature of the present invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings in which:
Like reference numerals refer to like parts throughout the several views of the drawings.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTSThroughout the several views of the drawings, the construction safety screen system of present invention is shown and is generally indicated as 10.
Referring initially to
The flexible net member 12 is surrounded by a flexible frame border 20 made from a resilient, flexible material, such as nylon rope. The flexible net member 12 is made from a resilient, flexible material, such as polypropelyne, and may be arranged in a pattern within the flexible frame border 20 leaving gaps 23 between individual segments 21 of the resilient, flexible material. The gaps in net member 12 serve to permit flow of wind therethrough for avoiding wind resistance hazards. Moreover, the gaps between individual segments 21 of the resilient, flexible material are sufficiently sized to prevent passage of an individual's body. In one embodiment, the flexible net member 12 includes individual segments 21 of resilient, flexible material aligned in a 2″×2″ grid.
