    Modular Guard Rail Assembly
    FIELD OF THE INVENTION
    The present invention relates to the field of rail assemblies. Specifically there is provided an easy to install guard rail assembly that may be assembled and installed without the aid of welding or soldering.
    BACKGROUND OF THE INVENTION
    In many constructions safety barriers or guard rails are required. Firstly, personal safety requires the erection of such rail, and secondly, it is also prevents the accidental dislodgement of articles which would otherwise cause a substantial safety hazard.
    While such guard railings meet safety requirements, they require more than one person and a fair amount of time to construct and often result in the destruction of the materials used when they are disassembled. Obviously, the additional labour and cost of materials used will add to the expense of the job.
    Many such railings also fail to pass the rigidity requirements of safety inspectors. As a result, various structures have been proposed to aid in the construction of safety barriers which prevent workmen from accidental falls and which meet strict safety guidelines. To a large extent, however, most of the proposed structures are impractical, expensive and too complicated to use.
    Consequently, a need exists for a portable and simple guard rail system which is effective in preventing accidental falls, meets safety guidelines and which can be assembled and disassembled in an efficient manner. Especially there is a need for a guard rail system which can be assembled and installed by the ultimate user without the aid of welding or soldering the without separate fastening means such as screws, rivets or the like for assembling the component parts of the fence to each other, and which can be assembled and installed with low-level skill and minimal tools.
    JPH 01168634 U discloses a guard rail assembly comprising a set of vertical bar elements of a rectangular cross section with two side walls, a frontal, and a rear wall, each bar element having at least one opening for receiving an upper horizontal bar element.
    JPH 01168634 U futher discloses a set of horizontal bar elements of a rectangular cross section with an upper, lower, frontal, and rear wall, each bar element having at least two pairs of slits (8) for receiving vertical bar element. Finally, JPH 01168634 U discloses elastic brackets for holding the vertical and horizontal bar elements in place when assembled.
    JPH 01168634 U does not discloses that each of the two slits extends orthogonally from the surface of rear wall of the bar element and 50-80% through the bar element, and that the opening in the vertical bar elements is designed so that a part of the front wall is fully open and 30-50% of the side walls is cut away, wherein the slits in said pair of slits of the upper bar element are positioned in a distance corresponding to the thickness of a vertical bar element, whereby the upper horizontal bar element mates with the opening in the vertical bar element.
    A need exists for a metal safety rail that is reusable, that quickly assembles and disassembles, that disassembles into two separate members to prevent cooperating elements from being lost or damaged, and that is more stable, force resistant and safer than comparable wooden safety rails. Further, the metal safety rail must meet all specifications established by safety agencies.
