Abstract
A metal safety rail for open floors of a building under construction includes a baseplate secured to a floor surface, a substantially vertical inner stanchion integrally joined to the baseplate, a substantially vertical outer stanchion slidably disposed over the inner stanchion, and at least one guard member secured to adjacent outer stanchions, whereby a safety rail is ultimately disposed about a peripheral portion of an open floor of a building under construction to prevent workers from falling from the open floor to the ground below.
Claims20
A safety rail that is disposed unattached upon a predetermined surface area comprising:
- a plurality of baseplates corresponding to a safety rail length formed from multiple rail sections, each one of said plurality of baseplates being separated from an adjacent baseplate a predetermined distance, at least one of said baseplates being disposed upon a predetermined surface area and remaining unattached to the predetermined surface area, thereby avoiding damage to the predetermined surface area;
- a pair of substantially vertical inner stanchions integrally joined to each one of said plurality of baseplates;
- a pair of substantially vertical outer stanchions, said outer stanchions being vertically joined together via at least one guard member, thereby forming a substantially vertical rail section having said pair of outer stanchions horizontally separated a predetermined distance that allows one stanchion of said pair of outer stanchions to slide upon a cooperating inner stanchion joined to one of said plurality of baseplates, said horizontal separation allowing an opposing outer stanchion of said pair of outer stanchions to simultaneously slide upon a cooperating inner stanchion joined to a baseplate adjacent to said one of said plurality of baseplates;
- and
- means for removably securing an outer stanchion disposed upon a cooperating inner stanchion, said removable securing means including an elongated sleeve integral with and extending from an upper surface, said sleeve having a longitudinal dimension and an inner diameter that cooperate to snugly receive and longitudinally engage a corresponding portion of a joining member of said removable securing means to provide rigidity and stability to said outer stanchions after said joining member is secured to said inner stanchion, whereby a plurality of said baseplates and said inner stanchions cooperated with a plurality of said rail sections to ultimately form a safety rail that remains vertically disposed about a predetermined surface area without attaching said baseplates to the predetermined surface area.

A safety rail that clamps upon structures supporting a predetermined periphery comprising:
- a plurality of baseplates corresponding to a safety rail length formed from multiple rail sections, each one of said plurality of baseplates being separated from an adjacent baseplate a predetermined distance, at least one of said baseplates having clamping means for securing said one baseplate upon a support structure that supports a portion of a predetermined periphery;
- a pair of substantially vertical inner stanchions integrally joined to each one of said plurality of baseplates;
- a pair of substantially vertical outer stanchions, said outer stanchions being vertically joined together via at least one guard member, thereby forming a substantially vertical rail section having said pair of outer stanchions horizontally separated a predetermined distance that allows one stanchion of said pair of outer stanchions to slide upon a cooperating inner stanchion joined to one of said plurality of baseplates, said horizontal separation allowing an opposing outer stanchion of said pair of outer stanchions to simultaneously slide upon a cooperating inner stanchion joined to a baseplate adjacent to said one of said plurality of baseplates;
- and
- means for removably securing an outer stanchion disposed upon a cooperating inner stanchion, whereby a plurality of said baseplates and said inner stanchions cooperated with a plurality of said rail sections to ultimately form a safety rail about a predetermined periphery.

A clamping base for a safety rail comprising:
- a clamping arm having a first retaining pad for engaging a corresponding side wall of a support structure;
- a stanchion base having a second retaining pad for engaging a corresponding side wall of the support structure, said stanchion base including a pair of substantially vertical inner stanchions integrally joined to top wall of a base member;
- a locking member continuously positioned upon a horizontal portion of said clamping arm, thereby allowing the use of said clamping base upon a support structure so long as the longitudinal dimension of said horizontal portion is longer than a corresponding dimension of the support structure;
- and
- means for forcibly compressing first and second retaining pads into forcible engagement with opposing side walls of a support structure, whereby said clamping base is rigidly secured to the support structure, and a rail section that is secured to said clamping base is maintained in a stationary vertical position.
