A standing umbrella has a mast on which the inner end of an outwardly and inwardly movable carrier beam is guided with the outer end of the beam carrying an umbrella stick of a collapsible umbrella and with the carrier beam being held by a connecting strut linkedly arranged between the upper end of the mast the carrier beam. A drive mechanism shifts the inner end of the carrier beam along the length of the mast and the mast has two guide tracks spaced from one another and so profiled that guide elements running there along and carried by the inner end of the mast are held by the shape of the tracks against movement transversely to the direction in which the inner end of the carrier beam is shifted; and the drive mechanism for shifting the inner end of the carrier beam and a drive mechanism for opening and closing the umbrella are so combined with one another that they operate simultaneously in common.
An umbrella includes a panel attached to a crown and supported by ribs. A runner is coupled to the ribs by stretchers to be movable with respect to the crown. A pole located beside the panel is arranged upright with a slide mounted thereon to be movable along the pole. An arm has an end pivoted to the slide and is further supported by a link pivoted to both the pole and the arm. A first rope to which the slide is attached is movably received in the pole and supported by an upper pulley and a crank whereby by actuating the crank the first rope moves the slide along the pole. A second rope movably received in the arm having an end fixed to the pole via a pulley fixed on the slide and an opposite end extending beyond the arm and through the crown to be fixed to the runner whereby by moving the slide along the pole, the arm is rotated between a closed position and an open position where the runner is moved toward the crown by the second rope. Spaced tabs are formed on the arm to be received in grooves defined in the crown when the arm is moved to the open positioned for securely attaching the panel to the arm thereby allowing the panel to be moved with the arm for adjusting the orientation thereof. A locking device is provided in the arm for selectively securing the second rope.
A stretching structure for sunshade body. The structure includes a stem, an auxiliary lever, a push lever, an upper beehive, a lower beehive, several upper support ribs, several lower support ribs, several cock members, several pivot blocks, several arch fitting blocks, several L-shaped fitting blocks and two metal cords. When stretching the sunshade body, a locating collar fitted on the stem is upwardly pushed or downwardly pulled and located by a locating handle. At this time, the upper support rib pivotally connected with the locating collar drives the auxiliary lever which drives the push lever and the lower support rib so as to upwardly and outwardly stretch open the upper and lower support ribs.
A sunshade comprises a supporting rod, a tube supported by the supporting rod, an elbow connected to an end of the tube, and a canopy support frame. A vertical section of the elbow includes two spaced lugs having a space therebetween, an upper wall defining the space including a toothed section. The canopy support frame includes an upper support base having ribs attached thereto for supporting a canopy, a lower support base having stretchers attached thereto for supporting the ribs, and a suspension member fixed to the upper support base to move therewith. The suspension member includes a toothed portion for releasable engagement with the toothed section of the elbow. The toothed portion of the suspension member is engaged with the toothed section of the elbow when the canopy reaches a fully open state.
A stand frame for an umbrella comprises a shaft, an umbrella frame, a foldable hanger arm hanging the umbrella frame, a height-adjustable device, and an angle-adjusting device. The stand frame for an umbrella utilizes the height-adjustable device and the angle-adjusting device to control the expansion/contraction and angular orientation of the umbrella frame thereof. The height-adjustable device provides a mechanism by which the middle section of the shaft can rotate horizontally, so as to move the umbrella frame about the shaft. A pull string extending from the shaft to the umbrella frame drives a vertical movement of the upper section of the shaft and the expansion of the umbrella frame simultaneously. A set of other pull strings are manipulated by the angle-adjusting device to vary the angular orientation of the umbrella frame in three dimensions.
A jib (8) can be extended and retracted on the mast (2) and supported by means of mutually parallel connecting struts (16, 18). The struts are articulated secured to the mast (2) and the jib (8), while the jib can be secured in the extended position by means of a first clip (36) and bears a folding canopy (10) at the end away from the mast (2). The jib (8) is guided on the mast (2) and the struts (16, 18) so as to swivel, and can be secured in the swiveled position by a securing device (26, 28).
