Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to a structural system for protecting recreational areas, such as a swimming pool, or a patio, or a children&#39;s sandbox. More particularly, this invention relates to a support structure for selectively suspending an umbrella or parasol over a designated area which is relatively remote from the actual point of support. 
     2. Description of the Prior Art 
     The art is represented by patio canopies and beach umbrellas which customarily provide a support column extending to the base of support at the center of the canopy or umbrella. There are available patio canopy constructions which embody the so-called European styling found in open-air cafes throughout Europe wherein a permanent base is located at a location offset from the point of utilization. In such European structures the canopy is cantilevered in the manner of a basket hoop on a backboard of a basket ball goal. 
     Somewhat similar cantilever support structures are also provided for water polo goals located at the ends of a swimming pool in which the game is played. 
     SUMMARY OF THE PRESENT INVENTION 
     The present invention contemplates the construction of a cantilevered holder for an umbrella or canopy which is portable and transportable and can be utilized effectively by women and children and senior citizens to provide a shaded area, for example, in an in-ground swimming pool, where the user does not want to leave the pool, but has had a sufficient exposure to the sun. 
     The conventional umbrella for recreational shading is approximately five feet above ground level and is capable of providing shade for two lounge chairs. By the present invention, there is provided an umbrella holder which consists of the usual vertical pole holder that is part of the umbrella unit. However, there is additionally provided a laterally extending mounting bar projecting at ground level to an area remote from the point of utilization. At an intermediate portion of the mounting bar, and in order to prevent angular rotation of the mounting bar, one or more stabilizing arms may be provided. At the free end of the mounting bar, a securing means or anchoring means may be provided. In one form of the invention, the anchoring means may constitute a hook which conveniently engages the edge of the pool apron, for example, a pool apron made of concrete and surrounding the pool to form a pool deck area. In another form of the invention, the anchoring means constitutes a stand, which may carry a ground engaging wheel means so that it may be easily and readily moved around to a selected location by someone of limited physical prowess. In order to give the stand added anchoring ability, it may further include a filling and drainage opening so that it may be weighted with a supply of water. 
     It is further contemplated by the present invention that the entire combination assemblage, i.e., the canopy, or umbrella, the pole, the mounting bar and the anchoring stand can be folded together in a compact form and handled by the user as a kit that is conveniently stored when not in active use.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The present invention has utility in any environment where it is desirable to shield a selected area which is remote from an accessible location so that it would be desirable to provide a cantilevered support which is compatible with existing umbrellas and which can be handled safely and effectively by women and children and senior citizens. 
     The structure of the present invention consists essentially of only four separate main parts: (1) a canopy, or umbrella which will be identified at 10; (2) an umbrella pole which will be identified at 20; (3) a mounting bar which will be identified at 30; and (4) an anchoring means which will be identified at 40. 
     Referring to the drawings, it will be noted that the canopy or umbrella is shown at 10 and constitutes a retractable umbrella of the usual type provided for use on patios or on open-air esplanades and cafes. One of the advantages of the present invention is that it can be effectively utilized to retrofit most commercially available umbrellas for use in the special use environments contemplated. 
     The umbrella 10 may comprise a cover 12, which in the illustrative embodiment of this disclosure is generally square. However, it could be round, or circular. Further, it can be made of any desirable material suited to the purpose of shielding against the sun and/or rain. In some instances, the cover 12 may comprise a heavy opaque material which completely blocks the sun&#39;s rays, while in other instances, the cover 12 may constitute a relatively diaphanous material which is lacy in character and/or it may be relatively transparent, or translucent, such as a sheet-form plastic film. 
     In any event, the cover 12 is a fabric or a sheet-form material which is held on a collapsible frame 13 of a first set of thin ribs 14 radiating from the top of the umbrella pole 20. A second set of thin ribs 16 is connected at one end to a sliding ring 17 carried by the pole 11 and connected at the other end to an intermediate portion of a corresponding one of the first set of ribs 14. 
     In order to support the umbrella 10 in an upright position, there is provided the second part, namely, the umbrella support pole 20 which provides an upright vertical support column to which the umbrella 10 is adjustably connected. The pole 20 of the present invention is shown as comprising a hollow tubular cylinder made of metal and sized to cooperate with the ring 17. In most constructions, there will be provided a latch and detent means so that the ring 17 can be selectively positioned and locked at an uppermost position on the pole 20 when the umbrella is open or at a lowermost position on the pole 20 when the umbrella is closed. 
     In a conventional prior art usage, the umbrella pole 20 is inserted into a heavy base member which is usually counter-weighted with sand or cement and which in many instances may be positioned underneath the midpoint of a table. The user can access the ring 17 and can raise or lower the umbrella at will. 
     In accordance with the principles of the present invention, however, it is contemplated that the umbrella or canopy 10 can be positioned over an inaccessible location, thereby to give protection and comfort to a user under circumstances where normal access would be difficult, if not impossible. For example, many persons of advanced years find that usage of a swimming pool offers the opportunity for excellent physical therapy as well as for comfort and enjoyment and relaxation. Such persons would like to avail themselves of these special benefits without undue exposure to the rays of the sun. 
     Thus there is shown in FIGS. 1 and 2 an in-ground swimming pool 50 having the usual side walls 51 extending below grade level and a bottom wall 52 so that the pool can be filled with a supply of water shown at 53. The ground surface in which the pool 50 is sunken is surmounted by an apron at ground level extending around the edge of the pool as shown at 54. In FIG. 1, the apron 54 comprises a concrete slab forming an extended pool deck 56 on which may be placed such pool side accessories such as deck chairs and possibly tables and/or lounge chairs. 
     The usual umbrella 10 is about five feet high if it is to protect two lounge chairs from the rays of the sun. Accordingly, to protect a remote area in the interior of the pool 50, i.e., an area which is inaccessible from the pool-side deck surface 56, the present invention contemplates the provision of a mounting bar 30. 
     The mounting bar 30 constitutes an elongated relatively thin member which is designed to extend at deck level, i.e., at the level of the deck 56, and to project from the deck 56 out over the water 53 in the pool 50. Such criterion is met by a metal cylindrical tube having at one end thereof a coupling joint 60, the structural details of which are illustrated in FIG. 3. The coupling joint 60 is a so-called swivel joint and in this disclosure the swivel joint has a ball and knuckle fitting which comprises a ball 61 which is rotatably journalled on a shaft 62 carried in a knuckle 63, formed on, or connected to, the outermost end of the mounting bar 30. The ball 61 has a male part 64 sized and shaped to be telescopically mated with the end of the umbrella pole 20. Thus, by rotatably positioning the ball 61 so that the umbrella pole 20 is at right angles to the mounting bar 30, the umbrella 10 will be positioned in upright position superjacent the pool 50 above the water 53. Thus, the mounting bar 30 extends away laterally from the reference axis or the pole 20 and the umbrella 10. 
     In order to lock the ball and knuckle joint in the selected position, each of the parts may be provided with appropriate mated openings 66 for receiving a cotter pin 67. In order to safeguard the mounting bar against inadvertent angular rotation which might tip the umbrella 10 into the water 53, the mounting bar 30 is provided with one or more stabilizing bars or arms 31 which may be connected to the bar 30 and which project laterally therefrom in engagement with the deck 56 
     At the opposite end of the mounting bar 30, there is provided the fourth element of the combination, namely, the anchoring means 40. In the form of the invention illustrated in FIG. 1, the anchoring means 40 takes the form of a stand 41 comprising a generally rectangular shaped box which is hollow on the inside to form a compartment 42. The compartment has a filling and drainage nozzle 43 in the top wall closed by a removable cap 44 so that a supply of ballast water may be charged into the compartment 42, thereby increasing the weight of the anchoring means 40 by about 50 to 70 pounds. 
     One or more wheels (two, in the exemplary embodiment of this disclosure) are mounted rotatably in one end of the stand 41 as shown at 65. The side walls of the stand 41 are appropriately recessed at 67 to accommodate the wheels. At the opposite end of the stand 41, a recess 68 is provided into which the end of ;the mounting bar 30 is inserted. The stand 41 and the mounting bar are locked in firm assembly with one another by appropriate locking means such as the pins 69. 
     The entire assembly folds up into an extremely manageable kit as shown in FIG. 6. The umbrella 10 has its cover retracted, the umbrella pole 20 is rotatably folded back upon the mounting bar 30, and the entire assembly is rotatably supported on the wheels 65 forming a part of the stand 41. The pole 20 prescribes a vertical reference axis which is coincident with the central axis of the umbrella 10. 
     In the form of the invention illustrated in FIG. 2, the pool 50 has an apron 54(a) which terminates in an outer edge 55. The outer end of the mounting bar 30 terminates in a hook 80 which is a U-shaped element formed and sized to clamp over the edge 55 of the apron 54(a) to firmly anchor the umbrella support against any possible lateral displacement. In this form of the invention, there is illustrated the use of two stabilizing members 31(a) connected to the pool-side portion of the mounting bar 30 and engaging the deck 56, so that the mounting bar 30 will not be rotated and tip the umbrella into the water 53. In all other respects the form of the invention of FIG. 2 is identical to that of FIG. 1 and like reference numerals have been employed to identify like parts. 
     Although minor modifications might be suggested by those versed in the art, it should be understood that I wish to embody within the scope of the patent warranted hereon all such modifications as reasonably and properly come within the scope of my contribution to the art.
