摘要:
An umbrella frame of the parallelogram type which includes a stick, a crown at one end of the stick, a main runner slidable on the stick, and an auxiliary runner slidable on the stick between the main runner and the crown. Stretcher members are hingedly connected to the main runner, while strut members are hinged to the auxiliary member and each to a mid point of each stretcher member. A dome rib is pivotally connected to each end of a stretcher member and extends inwardly from the end of the stretcher member a short distance where it is connected to a linkage member which in turn is hingedly connected to the strut member forming a quadrilateral parallelogram linkage with the dome rib.

An umbrella includes an anti-inversion mechanism that is configured to apply to each rib assembly a force that counters an inversion force that is applied to the umbrella. The anti-inversion mechanism includes a flexible elongated structure that is disposed exteriorly along the second rib part and has a first bent end that is attached to the second rib part by passing through an opening formed in the second rib part and being anchored within a hollow interior of the second rib part. The mechanism further includes a flexible wire having a first end attached to the flexible elongated structure of the anti-inversion mechanism and a second end attached to a rib tip that is located at a free distal end of the rib assembly.

The present invention relates to a portable shelter assembly. The assembly includes a support; and an expandable shelter for being supported by the support and expanding to shelter at least one person. The shelter includes ribs extending from the support. Each rib includes a proximal element pivotally mounted to the support. Each rib further includes a distal element extending from the proximal element and configured to move outwardly to expand the shelter when the proximal element pivots in a first direction. The ribs can be extended independently, one at a time.
