ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a kind of suspension type sun umbrella.
The suspension type sun umbrella, being also called a hanging umbrella, is a kind of large-sized umbrella suitable for use in the family lawn, at a swimming pool side, on a sea beach, in a park, tearoom, field, or other places used for leisure hour enjoyment or sun shading or rain sheltering. At present, the sun umbrellas currently used at home and abroad all include an umbrella column in the center of the umbrella surface, wherein the umbrella column is connected to a base while in use. For this reason, the user under the umbrella can not move about freely due to the obstacle of the column, and in this manner the sun shading area of the sun umbrella can not be fully utilized. In recent years, a kind of suspension type sun umbrella has appeared at home and abroad, which is a fixed type hanging umbrella, similar to a road lamp structure. This hanging umbrella structure, however, cannot be packed up or taken away while not in use. The “outside supporting type sun umbrella” of Patent No. 92221961.3 is also a road lamp type hanging umbrella, which not only affects the service of the umbrella and the environmental scenery, but also is quite inconvenient to use.
SUMMARY OF THE INVENTION
The object of the present invention is to overcome drawbacks of the prior art and provide a kind of hanging sun umbrella capable of being opened up and closed down at will, as well as being dismantled and transferred at will.
The present invention is realized as such: It comprises a column and an umbrella frame composed of a hanging arm; a hanging arm bracing; and 6-8 umbrella rods and associated umbrella rod bracings. The hanging arm is connected to the column and to the hanging arm bracing through square tube clamps, and the umbrella rods connect with the umbrella rod bracings through tube clamps. The hanging arm, hanging arm bracing, umbrella rods, and umbrella rod bracings are supported by upper and lower umbrella tray holders, in a hinged manner. Umbrella cloth is fitted on the umbrella frame. One end of the hanging arm is hinged on a movable holder of the hanging arm, which together with the hanging arm and a pull arm hinged to a pull arm fixed holder located at the column top end makes the umbrella frame take on a cantilever form. A crank lift is provided on the column to move the hanging arm movable holder upward and downward, for realizing opening and closing of the sun umbrella.
The present invention, as compared with the well-known prior art, will allow the sun umbrella to be opened and closed at will through a pull rope control in the crank lift, such that the umbrella will be in a fully folded state when shut down. The present design is of ingenious structure, pretty style, convenient to use, capable of being dismantled and transferred at will, and of a structure that avoids the hindrance characteristics of the column and enlarges the moving about range under the umbrella, and in this manner, provides a kind of sun shading and rain sheltering apparatus of breakthrough conception.
