Description

{Safety handrail with foldable two-stage structure}

The present invention relates to a safety guardrail having a folding two-tiered structure, and more particularly, to a safety guardrail having a two-tiered safety railway structure, The present invention relates to a safety guardrail having a folding two-tiered structure which is capable of stably supporting the weight of the upper frame as compared with a sliding manner of the upper frame.

The high work bench is widely used as a construction material for use as a work footing in the construction work of construction and civil works, and it is an essential construction material to be used in most construction sites. Such a high work platform has the advantages of easy assembly and disassembly and good mobility, but there is also a disadvantage that the frequency of industrial accidents such as falling due to falling or falling is very high while working on a high work platform.

In order to reduce the risk, a safety guardrail is installed at the upper part of the elevation workbench so that the worker is prevented from falling and the work is performed safely.

However, the safety railing described above has the following problems.

First, a safety accident occurs when the operator's hands are caught in the railing during the up and down sliding operation to adjust the height of the safety railing.

Second, as the frequency of use increases, breakage frequently occurs.

In order to solve such a problem, Japanese Patent Application Laid-Open No. 10-1472962 discloses a method for stably supporting a lifting movement of a first rail coupled to a height adjusting rod through a shovel, In addition, a second rail that is connected to the first rail and is folded can receive a resistance to the torque hinge, thereby preventing a safety accident when the second rail is folded and reducing the frequency of breakage of the safety rail have.

However, the conventional safety railing described above has a problem in that it can not sufficiently support the load of the second rail by supporting only the fixing pin of the second railing provided at the upper end of the first rail.
