First Claim
Patent Images
1. A pedestrian-operated machine comprising:
- a body supported for movement over the ground; and
a planar guard attached to said body and biased to extend away from the body toward the ground, wherein said planar guard is arranged to slidably retract in a generally vertical direction relative to the ground only when an object makes contact with said guard in a manner which exerts a force on said guard in an upward direction from the ground, thereby preventing lateral relative movement of objects with between said body and the ground.

Abstract
A safety guard for attachment to a pedestrian-operated or riding machine having rotatable blades utilizes at least one semi-rigid guard attached to the machine body and movable away from the ground when pushed upward by contact with an object while preventing lateral movement of objects under the machine. The moveable guard will act as a rigid barrier to an operator'"'"'s foot or leg and reduce the possibility of the machine overrunning the operator'"'"'s foot or leg, thereby minimizing injury from the rotatable blades.

6. A pedestrian-operated machine comprising:
-
a body supported for movement over the ground; and a guard attached to said body to permit generally vertical extension and retraction of the guard relative to the ground while preventing lateral relative movement of objects with respect to said body, wherein said guard includes a bracket defining a vertically elongated opening and a passive guard which is inserted into the vertically elongated opening and is vertically moveable therein. - View Dependent Claims (7, 8, 9, 10, 11)
