Abstract:
A device that allows safe and complete clearing of snow or other material away from obstacles such as, buildings, doors, vehicles, machinery, etc. The device attaches to and guides material into a plow, bucket, blower, snow blower, or other equipment allowing the machine operator to physically contact an obstacle being cleared around without causing harm or damage to the obstacle. The soft moveable flex edge of the device can touch and slide along the obstacle allowing more complete snow or other material removal. The flex edge can deflect back and away from an obstacle preventing damage to the obstacle. The device comprises a rigid frame with a flex edge on the outward end of the frame. The flex edge can embody many designs including but not limited to, a spring resistance deflection mechanism, a pivot mechanism or a retracting mechanism.
