Stanchion

DETAILED DESCRIPTION What is claimed is: 1.
A stanchion construction for clamping to a scaffold plate, comprising vertical support means including first and second vertically extending tubular support members, means for fixing said first and second support members in an adjusted telescopic position with one of said members extending outwardly from the other of said members by a predetermined amount, clamping means carried by said first and second tubular support members including a threaded cylinder on said first tubular support member, a bolt threaded into said cylinder and having an outer end with a first flat engagement surface, a second flat clamping surface carried by said second tubular member and parallel to and opposed to said first clamping surface, said bolt being threadably adjustable to move said first clamping surface toward and away from said second clamping surface, said first tubular member having a hand rail and at least one fitting extending outwardly from said first tubular member and having means thereon for supporting said hand rail at a spaced location above said first clamping surface.




Description:
The invention relates to a stanchion, more particularly to a stanchion or a supporting post suitable to be applied as the handrail easily attachable to the scaffolding for workers and working machines used for construction cites of architecture, ship building and repair, engineering work of roads and tunnels, etc.
In general, upon building construction and ship building, assembly and repair or engineering work of roads and tunnels most works are performed by using scaffolding considerably higher than ground surface.
Handrails are provided to such scaffoldings by equipping stanchion having pipes or ropes, which scaffoldings are assembled by arranging plates to the side of such objects to be constructed or repaired in order to enable the safe movement of workers or operating machinery such as crane and others.
As for road paving works, wires or ropes are stretched in order to limit construction cite and at the same time to keep off pedestrians and cars
