BACKGROUND OF THE INVENTION
When participating in outdoor activities such as camping or the beach, portable chairs are often used when shade from the sun is desired. Often, a separate stand is required to allow the umbrella to remain upright. It would be desirable to have an umbrella, which could be temporarily secured to a portable chair or a pair of chairs and used outside.
A. Field of the Invention
The present invention relates to securing a portable shade umbrella to a camping chair or a pair of camping chairs.
B. Prior Art
Prior art exists that relates to securing an umbrella to a portable chair. The Mungia U.S. Pat. No. 4,789,200 claims a clamp means secured to the rear surface of a chair. The present invention improves on this prior art patent because it allows the user to secure the umbrella to the legs of a chair. The Rogers U.S. Pat. No. 5,255,954 claims the use of an endless rod structure to secure an umbrella to a chair. The present invention uses a bracket system instead of an endless rod. The Booth U.S. Pat. No. 6,666,221 claims a combination chair and umbrella.
The present invention is a removable device that allows a user to secure an umbrella to the legs of a chair, if desired and differs substantially for the features found in the prior art.
BRIEF SUMMARY OF THE INVENTION
The present invention is a removable bracket system by which an umbrella could be secured to the legs of a camping chair or pair of chairs. The present invention may be easily removed from the frame of the chair when not in use. No modifications are made to the chair as the system is mounted directly to the structure of the chair.
The present device would allow the camper or person in the outdoors to mount an umbrella to the back of the portable chair or chairs without concern for the type of terrain or the condition of the terrain.
Because of its exposure to the elements the device should be made from durable, non-corrosive material. Plastic is probably a suitable material.
It is an object of this device to allow an individual to mount an umbrella to the back of one chair or between two chairs.

DETAILED DESCRIPTION OF THE EMBODIMENTS
The present invention is a device 5 which allows its user to attach a beach or patio umbrella 15 to the back of a folding camping chair 20, which has tubular frame elements. The user must first unfold the chair 20. The user may or may not secure the bottom ends of the legs of the chair 20 to the ground through the use of chair pegs 12. FIGS. 1,2
First Embodiment
In the first embodiment the user secures the top mounting plate 35T and the bottom mounting plate 35B to a desired location on the back leg of the chair 22. FIGS. 1,3 Because the plates must be able to support the weight of an umbrella 15 it should be made of sturdy material. The mounting plates are planar and of predetermined thickness and should be sturdy enough to support the weight of an umbrella.
Each mounting plate is identical in shape and has a plurality, preferably six, of holes 35H drilled through the mounting plates at desired locations. FIG. 3, 4 The six holes 35H are drilled in three pairs. One pair is drilled on one end, one pair is drilled in the center, and one pair is drilled on the opposite end. The position of the two outside sets of holes is determined by the specific location of the frame members of the chair. The middle set of holes is contemplated to be in the center of the respective mounting plates, 35B and 35T. FIGS. 1, 3
The bottom mounting plate 35B is aligned with the chair legs 22 below the seat of the chair. Once the desired location is determined, a “U” bolt 28 is inserted around the chair leg 22 and through the holes 35H on either end of the bottom mounting plate 35B. FIG. 3, 4 The portions of the “U” bolt which protrude through the holes are equipped with threaded ends. A flat washer 26F and a lock washer 26L are inserted over each threaded end and a wing nut 27 is screwed loosely at first to ensure alignment onto each threaded end. Although wing nuts are discussed to secure the device, other means of attachment may be used and may include lock nuts or bolts. The “U” bolts may be either round or square.
A third “U” bolt 30 is placed around the rear junction or crossed pieces of the rear center of the chair and is inserted through the center pair of holes in the bottom mounting plate 35B. A compression fitting 10 is inserted vertically between the protruding ends of the “U” bolt 30. FIG. 3, 4 A clamp 33 is inserted around the protruding ends in order to firmly secure the compression fitting 10 to the bottom mounting plate 35B. In order to secure the clamp 33, flat washers 34F and lock washers 34L are slipped over the protruding ends and wing nuts 36 are screwed tightly onto the threaded protruding ends of the “U” bolt 30. FIG. 4 Once tightened, the center assembly 32 provides stability to the user of the device 5 in the center of the device 5.
Once the mounting plates are secured to the frame of the chair and the means of securement is tightened and after the compression fittings 10 and the umbrella pole 17 is inserted through both compression fittings 10, the entire assembly 30 provides stability for the user of the device 5.
The next step is to secure the top mounting plate 35T to the chair; the top mounting plate 35T is aligned with the chair legs 22 above the sitting portion of the chair. Once the desired location is determined, a “U” bolt 28 is inserted around the chair leg 22 and through the holes on the ends of the mounting plate 35T. The portions of the “U” bolt which protrude through the holes are equipped with threaded ends. A flat washer 26F and a lock washer 26A are inserted over each threaded end and a wing nut 27 or other means of securement is screwed tightly onto each threaded end. FIG. 4
A third “U” bolt 30 is inserted through the center pair of holes in the top mounting plate 35T. A compression fitting 10 is inserted vertically between the protruding ends of the “U” bolt 30. A clamp 33 is inserted over the protruding ends in order to firmly secure the compression fitting 10 to the top mounting plate 35T. In order to secure the clamp 33, washers 34F and 34L are slipped over the protruding ends and wing nuts 36 are screwed tightly onto the threaded protruding ends of the “U” bolt 30. FIGS. 1,4
With the chair 20 unfolded and tent pegs 12 securing the feet of the chair legs 22 to the ground, the umbrella pole 17 may be inserted through the compression fitting 10 on the top mounting plate 35T and through the compression fitting 10 on the bottom mounting plate 35B and the device secured in place.
Second Embodiment
The second embodiment contemplates the use of this device with two camping chairs. If using a pair of chairs, the user secures one side of the mounting plates to one chair leg 22 and the other end to the other chair leg 25. FIG. 2 The top mounting plate 35T and the bottom mounting plate 35B are secured to the leg 22 of one chair and the leg 25 of another chair. The device 5 is attached using the same method as described above with the same hardware.
