Abstract
A lift system for a spa cover includes a first arm rotatable about a first pivotal connection with a side of a spa and pivotally connected to a spa cover, a lift mechanism configured to provide for rotation of the first arm about its pivotal connection to the side of the spa, and a mechanical linkage between the lift-assist device and the first arm.
Claims17
A lift system for a spa cover, comprising:
- a first arm rotatable about a first pivotal connection with a side of a spa and pivotally connected to a spa cover;
- a lift mechanism configured to provide for rotation of the first arm about its pivotal connection to the side of the spa;
- and
- a mechanical linkage between the lift mechanism and the first arm;
- wherein the lift mechanism is a linear actuator which is connected to the mechanical linkage at a point offset from the first pivotal connection.
