Abstract
Support means for foldable structures of the type having a roof of foldable material and a vertical mounting shaft staking perpendicularly to the ground. The interlocking support means consists of upper and lower interlocking members. A plurality of horizontal ribs are pivoted and clamped in the interlocking support means so that the ribs are held horizontally, but can fold down along the vertical shaft for transportation. The ribs have a channel cross-section. A rope extends from the end of one rib through the rib channel, through the interlocking mounting means and then through a second rib, whereby the ends of the rope may be used to stake down the structure and support side walls.
Claims10
A foldable umbrella structure comprising a collapsible canopy supported by an articulated frame, said frame comprising a vertically oriented shaft having a stationary hub fixed at its upper end and a moveable hub slidably axially and rotatable thereon relative to the stationary hub, a plurality of elongated ribs pivotally mounted at one end to said stationary hub for movement between a collapsed position in which said ribs are parallel to said shaft and an open position in which said ribs extend horizontally substantially perpendicular to said shaft, said slidable hub being releasably securable in engagement with said fixed hub to clamp said ribs therebetween when in said open position and maintain said ribs in cantilevered extension from said shaft.
A foldable structure for forming umbrellas, tents, and the like, comprising a vertical shaft having a plurality of arms pivotally mounted at one end to the top of said shaft and being releasably secured in a horizontally extending position, a continuous rope passing from one of a pair of selected arms to the other of the pair and passing from the free ends of each of the arms in the pair, the free ends of said rope extending from said arms and being secured to the ground whereby said rope aids in staking said structure and define peripheral walls therefor.
