Japanese Patent JPS49102041
Kind Code:
A
Abstract:
The safety brake is adapted for use in conjunction with scaffolding or other apparatus in position on the tensioned line between a traction device and the point to which the line is attached. The housing would be attached to the apparatus supported by the traction device. The tensioned line passes through the housing between the two gripping shoes, one of which is spring loaded in a direction parallel to the path of the line. The other shoe is normally latched in a position permitting clearance for the rope between the shoes but is spring biased along a path converging with that of the first shoe so that upon release it will move to engage the rope whereupon the other shoe starts moving with the first. At this point the rope is gripped and the gripping force increases due to the converging paths of the shoes. The spring loading the passive shoe is compressed to absorb the shock of grabbing the rope and prevent breaking the rope as could occur with an instantaneous stop.
