Abstract
A gas spring for supporting a cab enclosure pivotably mounted to the body of a skid-steer vehicle. A stop tube is mounted to a piston rod and is telescopically cooperable with a cylinder body. Two parallel slots extend in a transverse direction through the stop tube. A stop slide has a pair of legs which are adapted to slide within the slots of a stop tube. A release portion of the stop slide is sized to permit the cylinder body to pass between the legs, while a stop portion is sized to prevent the cylinder body from passing between the legs. A spring urges the stop slide toward a stop position at which the stop portion of the stop slide is aligned with the cylinder body when the piston rod is extended. The cab enclosure is thereby latched to a tilt-back position. To lower the cab enclosure, the stop slide must be manually moved to a release position at which the release portion is aligned with the cylinder body, thereby permitting the cylinder body to pass between the legs of the stop slide with the piston rod retracted therein. A release cable coupled between a forward end of the cab enclosure and the stop slide can be actuated to conveniently move the step slide to its release p…
