The patio umbrella has a ledge positioned on the pole, and a spring slidably supported on the pole between the hub and the ledge. The patio umbrella can also have at least one stretcher having a first end pivotally coupled to one of the secondary ribs, and a second end pivotally coupled to the ledge.
Claims12
A patio umbrella comprising:
- a pole;
- a plurality of primary ribs extending from the pole, the plurality of primary ribs assuming an open position where the plurality of primary ribs are generally perpendicular to the pole, and assuming a closed position where the plurality of primary ribs are generally parallel to the pole;
- a hub slidably supported on the pole;
- a plurality of secondary ribs, each having a first end pivotally coupled to the hub and a second end pivotally coupled to one of the primary ribs;
- a ledge positioned on the pole;
- at least one stretcher having a first end pivotally coupled to one of the secondary ribs, and a second end pivotally coupled to the ledge;
- a spring slidably supported on the pole between the hub and the ledge;
- and
- wherein the plurality of primary ribs are locked in the closed position based solely on positioning the at least one stretcher in a vertical orientation.
A patio umbrella comprising:
- a pole;
- a plurality of primary ribs extending from the pole;
- a hub slidably supported on the pole;
- a plurality of secondary ribs, each having a first end pivotally coupled to the hub and a second end pivotally coupled to one of the primary ribs;
- a ledge positioned on the pole;
- a spring slidably supported on the pole between the hub and the ledge;
- and
- a handle attached to the ledge.
A method of opening a patio umbrella, comprising:
- a. providing a patio umbrella having
- a pole;
- a plurality of primary ribs extending from the pole, each of the plurality of primary ribs having a bottom side;
- a hub slidably supported on the pole;
- a plurality of secondary ribs, each having a first end pivotally coupled to the hub and a second end pivotally coupled to one of the primary ribs;
- a ledge positioned on the pole;
- and
- a spring slidably supported on the pole between the hub and the ledge, the spring being restrained from extension;
- and
- b. moving the secondary ribs radially outwardly solely by providing an upward force at the bottom side of one of the plurality of primary ribs to allow the bias of the spring to extend the spring.
A method of closing and locking a patio umbrella, comprising:
- a. providing a patio umbrella having
- a pole;
- a plurality of primary ribs extending from the pole;
- a hub slidably supported on the pole;
- a plurality of secondary ribs, each having a first end pivotally coupled to the hub and a second end pivotally coupled to one of the primary ribs;
- a ledge positioned on the pole;
- at least one stretcher having a first end pivotally coupled to one of the secondary ribs, and a second end pivotally coupled to the ledge;
- and
- a spring slidably supported on the pole between the hub and the ledge;
- and
- b. applying a downward force to one or more of the primary ribs to push the primary ribs vertically downward;
- c. locking the primary ribs in a position that is generally parallel to the pole solely by positioning the stretchers in a generally vertical orientation to restrain the bias of the spring.
