Abstract

PURPOSE: To always impart suitable tension to a device for tightening a handrail without applying excessive tension to the handrail by constructing not to trace a suspended weight downwardly when running resistance is increased for short time by providing a dashpot thereat.
CONSTITUTION: In a device for tightening a handrail using a suspended weight such as, for example, tightening the handrail 1 of an escalator by means of the downward movement of a weight wheel 12 by means of its self-weight to hold the lowered position by the engagement of a rack 14 provided downwardly of a weight slide 13 with a pawl 15, a dashpot 21 is provided to impart large time constant to the downward movement of the weight 12 at the lower end of the rack 14. Thus, it can prevent the weight 12 from downwardly lowering when the running resistance is increased for short time of the handrail 1 to effectively operate against the aging elongation to thereby maintain the handrail 1 in predetermined tightened state.
