ABSTRACT SAFETY DEVICE FOR LADDERS. The device is a substantially rectangular frame which can loosely girdle a ladder for sliding movement along the ladder and across the ladder from front to back, The frame has a U-shaped abutment 15 in one longer side 12; this abutment lies at the front side of the ladder and extends towards the ladder. When the device is moved rearwards so that side 12 abuts the front of the ladder, the abutment 15 extends between the ladder stiles 21 into the longitudinal plane of the rungs 22. The device has a spring clip 14 in its rear side 13 and can be attached to a person's belt or harness. In use the person can move up and down the ladder with the safety device hanging forwards (A) so that the abutment does not engage the rungs. If the person slips his movement will draw the device rearwards and bring the abutment into the space between two rungs (B). A short downward movement of the device will then bring the abutment to overlie the lower rung (C) and arrest any further downward movement of the device and of the person attached to it.
