Benefits of technology

The present invention provides a temporary guardrail for an unprotected staircase that can be easily assembled, installed, and disassembled for reuse at different sites. The guardrail includes a safety section, a support section, and a stabilizing section that work together to create a secure and stable barrier on the staircase. The upper and lower railings are telescopingly interactive concentric tubes that can be fixed in a predetermined configuration using pins and wing nuts. A netting can also be used to further enhance safety. The technical effects of this invention include improved safety, ease of assembly and disassembly, and flexibility for reuse at different sites.

Problems solved by technology

Of particular concern here is the hazard that is presented when a staircase is being constructed for a building, and is to be used during construction, but which remains unprotected for extended periods of time.
Specifically, the hazardous condition is created when such staircases have no guardrails to prevent workers from falling off the otherwise unprotected staircase.

Embodiment Construction

[0017]Initially referring to FIG. 1, a guardrail in accordance with the present invention is shown and is generally designated 10. In FIG. 1, the guardrail 10 is shown assembled and installed on a staircase 12. A more comprehensive structural appreciation of the guardrail 10, however, will be had by cross-referencing FIG. 1 with FIG. 2.

[0018]With reference to FIG. 2 it will be seen that the guardrail 10 essentially includes three prefabricated sections. They are: a safety section 14, a support section 16 and a stabilizing section 18.

[0019]In detail, FIGS. 1 and 2 show that the safety section 14 includes, in combination, an upper railing 20, a bottom baluster 22, and a top baluster 24. A hinge 26 interconnects the bottom baluster 22 with the upper railing 20, and a hinge 28 interconnects the top baluster 24 with the upper railing 20. Also, it will be seen that an attachment pad 30 is provided for the bottom baluster 22 and, similarly, an attachment pad 32 is provided for the top balu...

Abstract

A temporary guardrail for an unprotected staircase is assembled and installed using prefabricated sections. One section is a safety section that includes an adjustable length upper railing, with a pair of balusters respectively hinged to each end of the upper railing. Another section is a support section having an adjustable length lower railing that is engaged between the balusters of the safety section and which, when assembled with the safety section, is oriented parallel to the upper railing. The safety and support sections are then stiffened to account for an incline angle α that is defined by the staircase. Also included are structures which can be engaged with the temporary guardrail to stabilize it on the staircase.

Description

FIELD OF THE INVENTION[0001]The present invention pertains generally to safety barriers that are useful for protecting workers at construction sites. More particularly, the present invention pertains to temporary structures that can be installed on staircases, which are located inside / outside a building during construction, to help prevent workers from falling off an otherwise unprotected staircase during the construction of the building. The present invention is particularly, but not exclusively, useful as a temporary guardrail having prefabricated sections which can be assembled and installed on a staircase at a construction site, and then disassembled after use for removal and subsequent use at another construction site.BACKGROUND OF THE INVENTION[0002]Whether the use of safety equipment is required at a construction site to prevent death or injury is always a paramount concern. Of particular concern here is the hazard that is presented when a staircase is being constructed for a...
