Abstract
Disclosed is a smart ladder. The smart ladder may be A-frame type of ladders, such as A-frame ladders and A-frame platform ladders. The smart ladder includes right and left outrigger leg units which are swiveled coupled to the right and left sides of the ladder to provide side support. The ladder includes brace units facilitate in folding and unfolding of the ladder as well as the outrigger legs. An electronic system, which includes a sensor network, a processor and a warning system, is provided. The sensor network senses side inclination angle of the ladder and side force on the outriggers and predict potential hazards from exceeding load and angle thresholds. This enhances safe operation of the ladder and avoids injuries to the user and others in the vicinity.
Claims14
A ladder comprising:
- a front rail unit having a plurality of steps and a rear rail unit;
- a right outrigger leg unit coupled to a right side of the ladder, wherein the right outrigger leg unit is configured to provide side support on the right side of the ladder;
- a left outrigger leg unit coupled to a left side of the ladder, wherein the left outrigger leg unit is configured to provide side support on the left side of the ladder;
- and
- an electronic system which enhances safe operation of the ladder, the electronic system comprises:
- a sensor network having a plurality of sensors for sensing force asserted on the outrigger leg units, an angle of inclination and acceleration of the ladder;
- and
- a processing unit coupled to the sensor network, the processing unit processes information from the sensor network and generates a warning alert of potential unsafe use of the ladder;
- a right swivel joint for coupling the right outrigger leg unit to the right side of the ladder, wherein the right swivel joint comprises right force sensors of the sensor network to measure force asserted on the right outrigger leg unit;
- a left swivel joint for coupling the left outrigger leg unit to the left side of the ladder, wherein the left swivel joint comprises left force sensors of the sensor network to measure force asserted on the left outrigger leg unit.
