Description

RELATED APPLICATIONS

[0001] The present patent application is a Continuation-In-Part of U.S. patent application Ser. No. 13/480,396, filed May 24, 2012, in the name of the same inventor listed above, and entitled, "ADJUSTABLE LENGTH SCAFFOLDING AND METHOD THEREFOR".

BACKGROUND

[0002] The present invention relates generally to a scaffolding and, more specifically, to an adjustable length scaffolding for use in an attic.

[0003] Worker safety is of great importance to both construction industry employers and employees. Worker safety is of such importance that a federal agency, the Occupational Safety and Health Administration (OSHA), was created to draft, inspect, and enforcing work place safety and health regulations.

[0004] As disclosed in U.S. Pat. No. 5,664,391, various scaffolding and safety systems have been designed. Some are engineered from the ground up while others are designed to hang off the roof or wall structure. All of these scaffold systems, however, suffer from a common defect--the enormous amount of time to assemble, erect, reposition, and take down such systems.

[0005] There are hanging scaffolds, scaffold systems that are affixed to the roof and hang over the cave to support a working platform, that have been designed to reduce the amount of labor and time necessary for scaffold assembly/disassembly. However, while saving some time, these hanging scaffolds are not without their own shortcomings.

[0006] Furthermore, many hanging scaffold systems are theoretically designed for easy pre-assembly prior to deployment, again with the objective of reducing labor costs and cutting productivity losses. Most of these hanging scaffold systems, however, are not as stable as ground based scaffold systems

[0007] Further, hanging scaffold systems require a roof anchoring point that is able to withstand thousands of pounds of force in several directions while the construction work is in progress. Typically, the roof anchor is nailed, bolted or fixedly attached to the roof to provide the necessary safety margin. However, this results in a roof anchoring system that requires additional time and effort to remove and reposition, thereby reducing the time savings associated with the hanging scaffold system.

[0008] An additional issue is that the hanging scaffold systems are only designed to hang from the exterior surface of the roof. The hanging scaffolding system was not designed for use in an attic crawl space.

[0009] Therefore, it would be desirable to provide a circuit and method that overcomes the above problems.

DETAILED DESCRIPTION

[0033] Referring now to the Figures, an attic scaffolding system 10 is shown. The system 10 is designed to be used in an attic area 12 of a house and or building. The attic area 12 may be defined as the area between the ceiling 14 and a roof section formed by trusses 16. The system 10 is designed to be positioned on existing rafters 18 in the attic area 12. The system 10 may be used to allow a person to work within the attic area 12. Presently, when working in the attic area 12, workers stand on the individual rafters 18. Alternatively, individual boards may be used to allow a person to stand in between consecutive rafters 18. However, the individual board needs to be lifted and moved every time the worker moves.

[0034] The system 10 is designed to quickly and easily attach and lock multiple planks 20 together. This allows for a removable floor to be formed on the rafters 18. As stated above, the system 10 is formed of a plurality of plank members 20. Each plank member 20, and thus the system 10, is of a size to allow the plank members 20 to be carried through an attic opening 11. The plank members 20 may be formed of an electrically non-conductive material.

[0035] As shown in FIG. 2, a top surface 20A of the plank member 20 may have markings 22. The markings 22 may be formed around one or more edges on the top surface of the plank member 20. The markings 22 may be used as a warning indictor to let a person know that they are near the edge of the plank member 20. The marking 22 may be a red strip, a fluorescent yellow/green strip, a grip strip, or the like. The above listing is given an example and should not be seen in a limiting manner.

[0036] Located on a bottom surface 20C of the plank member 20 may be a latching device 40. The latching device 40 may be used to secure the plank member to a rafter 18. The latching device 40 may be used to prevent the plank member 20 from moving/sliding when positioned on a rafter 18. The latching device 40 may be a hook or the like.

[0037] Located on one or more side surfaces 20B of each plank member 20 may be an attachment mechanism 24.
