Abstract

The present invention Universal extra shade tent structure to hand held umbrella refers to a shelter from a folding hand umbrella and a double version combination of separated additional tent sections that may be connected to the umbrella skeleton arms at several end points of the umbrella, when the umbrella is in open form. The first version of the separated additional tent section consists of several telescopic or other types of poles, soft light walls, and an underlay. The hard poles are joined to the umbrella skeleton arms by a sliding, or other type of connectors and connect to attach by the other end to natural soil, ground, grass, sand, or an underlay that provides fixation or to any outdoor beds, or to other objects for tent stability. When the shelter is in standing form, the lever handle of the umbrella can be removed by twisting off or otherwise removing from the structure, or minimized by sliding upward, or bending horizontally to the side into a compact position. The second version of additional tent sections is comprised of telescopic or other extensions to the umbrella hand lever to form a central supporting pole, several soft pulls, soft light walls, ground anchors, and an underlay. The standing form of the tent structure consists of a lever extension connected to the umbrella hand lever that reaches to the ground, and of soft pulls connected to the umbrella skeleton and at the other end are joined to ground, ground anchors, outdoor bed, an underlay, or to other objects or places, which help maintain the umbrella-tent structure in a vertical position. In both variations, the umbrella and the affixed tent poles or pulls combine to create the skeleton of a tent structure wherein portable side walls from flexible materials can be optionally affixed to the tent poles or pulls on one, two, three, four, or more sides to provide desired amounts of enclosure, shade, or protection from the elements, allowing the user to regulate the desired amount of structural enclosure. The variation of a Hand held umbrella to universal extra shade tent structure wherein the umbrella skeleton consists of three or more telescopic arm-pole combinations made from collapsible materials that can turn and come back to departure, wherein the telescopic pole is inside arms in the umbrella unfolding position, and outside arms, when telescopic poles support the tent structure in the unfolding umbrella-tent position, herewith soft walls and a soft umbrella roof can be separate or as one product, and walls slide-connected to telescopic arm-poles can partly or fully cover the unfolding umbrella-tent structure. The present invention has universal uses as a hand umbrella, beach umbrella, shelter, canopy, tent, and group hand held umbrella that give full or partial protection that can be carried by one or a few people.

BACKGROUND OF THE INVENTION

Statement of the field of Endeavor: United States Patent Class 135.
The present invention relates to Universal extra shade tent structure to hand held umbrella. More particularly, the present invention relates to the double use of a hand held umbrella to provide a central support umbrella roof and pole or pull attachments to comprise the main skeleton to which optional wall attachments can be added to form a partial or complete enclosure. Hand held umbrella, beach umbrella, stationary or other umbrella can be connected to the Universal extra tent shade structure that can have a double use as a, shelter, canopy, and tent with complete or partial enclosure.

DESCRIPTION OF THE PRIOR ART

Devices such as umbrellas, canopies, and tents are widely used outdoors. They are familiar features of gardens, yards, patios, restaurants, beaches, pools, parks and many other places.
There presently exist many variations of umbrellas. For example: hand held umbrellas, beach umbrellas, table umbrellas, and other umbrellas. There are many patents for the umbrella apparatus. Every patent of umbrella is always comprised of a central handle and folding skeleton, which can slide along a handle to support the umbrella skeleton in an unfolding position.
Inventors have proposed protective enclosures for temporary outdoor structures. Additionally, some inventors have proposed mechanisms to extend and retract umbrella enclosures.
FOR EXAMPLE, U.S. Pat. No. 144,792, November 1873, to Prentiss describes a portable combination of umbrella and netting. The net material is attached to the periphery of the umbrella's canopy. This enclosure is long enough to reach the ground.
FOR EXAMPLE, U.S. Pat. No. 2,502,984, April 1950, to Parmenter describes an umbrella said to provide enhanced, adjustable protection from the elements.
FOR EXAMPLE, U.S. Pat. No. 2,546,228, March 1951, to Martini describes a transparent shield suspended from an umbrella.
FOR EXAMPLE, U.S. Pat. No. 2,661,752, December 1953, to Kampf et al. describes a “garden” type umbrella with a hollow support. The support contains a cord used to manipulate the umbrella's canopy. One end of the cord is attached to a runner on the support. The cord's other end, after passing through a pulley, is connected to a manually operated reel.
FOR EXAMPLE, U.S. Pat. No. 3,477,453, November 1969, to D'Ulisse and D'ulisse describes a net for converting an umbrella to a shelter from insects. It consists of a dome-shaped net covering for beach-type umbrellas, adapted to rest on the roof of the umbrella. It possesses sidewalls that extend to the ground. A hole is provided in the center of the covering to permit protrusion of the umbrella support pole. Loops are provided at the bottom perimeter of the wall for the purpose of staking the walls to the ground. Devices are provided on the dome for securing walls to the umbrella.
FOR EXAMPLE, U.S. Pat. No. 4,022,233, May 1977, to Grundman describes an umbrella with an attached retractable protective material.
FOR EXAMPLE, U.S. Pat. No. 4,086,931, May 1978, to Hall describes an umbrella whose support is located off-center, at the side of its canopy. The space under the umbrella is enclosed by means of fabric segments suspended from its periphery.
FOR EXAMPLE, U.S. Pat. No. 4,202,363, May 1980, to Watts et al. describes a collapsible, combination umbrella and tent. The support frame is attached to two central hubs mounted on a central pole. Movement of these hubs facilitates erection and collapsing of the structure and its covering.
FOR EXAMPLE, U.S. Pat. No. 5,678,587, October 1997, to Bilotti describes an umbrella net that provides a drawstring for adjusting the height of the umbrella's net wall. It also offers a method for withdrawing the wall into a sleeve-like storage space located under the peripheral edge of the umbrella.
FOR EXAMPLE, U.S. Pat. No. 5,806,547, September 1998, to Derlinga describes a combination umbrella and gazebo. Walls dropped from the canopy of the umbrella define the structure as a gazebo. A stepped sequence of cords is attached at one end to a crank. The cords provide a way to raise and lower the sides.
FOR EXAMPLE, U.S. Pat. No. 6,009,891, January 2000, to Surface, Decker, and Fanti describes a screen enclosure system providing a tether system attachable to the umbrella and shaped to form an exoskeleton over the umbrella The skeleton is made by attaching many individual tethers to the umbrella over the spines of the umbrella. Also provided is a screening system attached to the exoskeleton by fasteners.
FOR EXAMPLE, U.S. patent application Ser. No. 2002/0108645, August 2002 to Andrea Beyer, Steven Beyer, relates to an umbrella, tent, or canopy, specifically to an umbrella with a storage chamber for an enclosure canopy of netting, and having mechanisms for canopy deployment, retraction, and interchange.
Collapsible tents, such as umbrella tents, are well known in the art. The term “umbrella tent” is commonly used in the trade because the frames for such tents can be erected and collapsed in much the same manner as an umbrella.
Some exemplary collapsible umbrella-tents are shown in, for example, U.S. patent application Ser. No. 2001/0007260 (G.Rousselle et al ); U.S. Pat. No. 5,871,026 {Tu Lin}; U.S. Pat. No. 5,230,358 (Forell); U.S. Pat. No. 4,945,936 (D. Surrendi); U.S. Pat. No. 4,202,363 (Watts et al.); U.S. Pat. No. 3,929,146 (Maiken); and U.S. Pat. No. 2,771,087 (Simonson). In these structures, there is no handle at the center of the umbrella-tent skeleton. Instead of a handle, there exists a soft cord or a frame locking mechanism.
There are many known kinds of hand held umbrella's. There are many known kinds of tents. There are many known kinds of umbrella-tents, whose skeleton can be erected and collapsed in much the same manner as an umbrella.
There are no prototype patents of any extra tent/shelter/structure, which is connected together with the skeleton of hand held or other umbrella that can be used as a universal comfortable shelter, canopy, or other tent structure with complete or partial enclosure.
There are no prototype patents of hand held umbrellas to any extra tent structure, whose skeleton arms, as needed, can be connected to separate parts of extra tent structures, and whose hand held lever handle, in the form of the umbrella-tent structure, can be disconnected, or by other way, can remove or shift from its vertical position under the umbrella skeleton roof.
