Lift assist mechanism for retractable awning |
摘要 |
A mechanism is disclosed for assisting an operator of a retractable awning in lifting the awning to a desired elevation. The mechanism includes a pair of back-to-back gas spring units which are operatively connected to relatively sliding telescoping members of a support arm for the awning to bias the support arm outwardly in a direction to assist in lifting the awning into a desired orientation. In one embodiment of the mechanism, a compression spring is provided in axial alignment with the gas spring units to provide an elongated stroke for additional assistance in attaining abnormal elevation of the awning.
