ABSTRACT:
FIELD OF THE INVENTION
The present invention generally relates to a rope-operated large-sized umbrella, such as a beach umbrella and a garden umbrella, and in particular an umbrella of the type with an orientation-adjustable umbrella panel.
BACKGROUND OF THE INVENTION
Conventional umbrellas comprise a center post on which radially extending ribs are mounted for supporting a panel. A runner is movably mounted on the center post for manual operation of opening the umbrella. For a large-sized umbrella, such as a beach umbrella and a garden umbrella, the center post occupies the centermost space and often interferes with activity occurring under the umbrella panel. Thus a full exploitation of the space covered by the panel is in general not possible.
Taiwan Patent Application No. 86202611 discloses an umbrella structure in which the panel is supported by a pole located beside the panel, rather than at a center of the panel. A rope system is adapted to control opening/closing of the panel. This structure allows a full exploitation of the space covered by the panel.
However, the panel of the above mentioned large-sized umbrella is fixed at a particular direction. Changing direction of the panel in response to the orientation of the sun is generally impossible.
Thus, it is desired to provide an umbrella structure for overcoming the above problem.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide an umbrella supported by a pole located adjacent a panel of the umbrella, the panel being operated by a rope system for opening/closing the panel in a stepless fashion.
Another object of the present invention is to provide an umbrella comprising a panel supported by ribs radially extending from a runner, the runner being coupled to a rope system controlled by a crank device, to be moved toward/away from a crown of the panel for opening/closing the umbrella.
A further object of the present invention is to provide an umbrella comprising a panel mounted to a crown, the crown being selectively and releaseably attached to an end of an arm for being rotated with the arm thereby adjusting the orientation thereof.
Yet a further object of the present invention is to provide an umbrella comprising a panel selectively and releaseably attached to an arm supported by a pole located beside the panel for being movable with the arm to adjust the orientation thereof, the panel and the arm being operated by a rope system that is controlled by a crank device.
In accordance with the present invention, there is provided an umbrella comprising 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 is movably received in the arm and has an end fixed to the pole via a pulley fixed on the slide. An opposite end of the second rope extends 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 rm, to thereby allow 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.
