Folding assisting arm assembly for lift gates

摘要

The present invention provides folding assisting arm assembly for lift gates. In one embodiment, the folding assisting arm assembly comprises a folding assisting apparatus for a lift gate having a platform with a foldable section. The apparatus comprises an elongated arm, and a pivot axle, wherein a proximal end of the elongated arm is pivotably mounted on the pivot axle. The apparatus further comprises a spring for spring loading the elongated arm. When the folding assisting apparatus is mounted on the lift gate proximate the platform, a biasing tension in the spring urges a distal end of the elongated arm on the foldable section of the lift platform during a portion of movement of the lift platform to maintain the foldable section folded.

主权项

1. A folding assisting apparatus for a lift gate having a platform coupled to linkages for supporting the platform, the platform having a foldable section, the apparatus comprising:
an elongated arm; a pivot axle, wherein a proximal end of the elongated arm is pivotably mounted on the pivot axle; and a spring for spring loading the elongated arm about the pivot axle; wherein when the folding assisting apparatus is mounted on the lift gate proximate said platform such that a distal end of the elongated arm remains detached from the platform, a biasing tension in the spring urges a distal end of the elongated arm on the foldable section of the lift platform during a portion of movement of the lift platform, to maintain the foldable section folded; wherein the biasing tension in the spring causes the elongated arm to remain urged against the foldable section while allowing the elongated arm to gradually recline by pivoting about the pivot axle and compressing the spring due to the weight of the lift platform bearing on the elongated arm as the lift platform rotates during said portion of movement of the lift platform.
