The present invention relates generally to anchoring systems and, more particularly, to beach umbrella anchoring systems.
Beach umbrellas are becoming an increasingly popular sight in many outdoor areas. Beach umbrellas are a convenient way to provide a shady place to rest and cool off, and a way to help prevent harmful sun exposure and sun burns. They are especially useful at the beach, sporting events, or other outdoor areas where a person will be exposed to the sun for long periods of time and not have access to shade or other sun blocking methods.
Conventional beach umbrellas can be mounted directly in the ground or directly into the sand. The most common methods employed to secure a beach umbrella is to push the umbrella shaft as far as one can in to the sand, or to dig a hole, place the umbrella shaft into hole and then fill-in the hole. Often, this proves unsatisfactory, as the sand is too difficult to dig or is too loose such that it will not compact and provide adequate support. Even if one is able to dig a hole that is deep enough, or have some method of anchoring the umbrella well enough to stay upright in the wind, the umbrella canopy often folds or buckles or turns inside out as it is not strong enough to withstand stronger winds.
Typically, outings at a beach or venue where an umbrella is employed include meals and/or drinks. They also typically include a variety of activities where it may be necessary to store items such as keys, electronic devices and the like. A beach towel is the usual place to put these items. However, when placed on a beach towel, keys and electronic devices (e.g., phones) can get sandy, wet or lost. Furthermore, food and drinks can likewise get sandy, wet and lost. Drinks may even be spilled.
A variety of products have been developed to aid in securing or stabilizing an umbrella. For these devices to be useful, they must be lightweight and portable so that the user can easily take them to their destination, install them, and remove them without excessive effort. These devices must also be sturdy enough to withstand gusts of wind, people bumping into them, and other environmental factors. Therefore, the anchoring method or mechanism must not only be convenient and easy to use, but it must also form a secure and stable locking position.
Some umbrella base stands have been designed so that the umbrella pole mounts within a cylinder which can be screwed into the sand or dirt. U.S. Design Pat. No. D630,834 to Cohen entitled “Anchor Auger for Beach Umbrella” illustrates an auger or drill method, where a spiral shaped auger device is attached to an umbrella shaft for the purpose of boring a hole into the sand deep enough to secure the umbrella shaft.
There are several disadvantages to these types of methods. For example, it is often difficult for the average person to screw these devices to a depth necessary to properly support the umbrella. Furthermore, if the sand or ground material is too loosely packed, there will not be enough density to support the umbrella. Also, in cases where the angle of the umbrella shaft must be changed to compensate for the movement of the sun, the entire process needs to be repeated.
Other types of umbrella base stands, such as those used in home patios, utilize a heavy or bulky base to support the umbrella. An example of such a stand is shown in U.S. Published Patent Application No. 2005/01899005 to Smith, et al. entitled “Umbrella Base”. The disadvantage of these types of products is that they are difficult to transport to other locations (due to their weight) such as the beach.
Still other umbrella base stands are designed to receive and hold an umbrella shaft, and are then weighted down with sand or some other material to hold the entire apparatus in place. U.S. Published Patent Application No. 2002/0036008 to Hickam, et al. entitled “Umbrella Base Stand and Table” and U.S. Pat. No. 5,452,877 to Riffle, et al. entitled “Beach Umbrella Anchor Bag” show two such techniques.
The disadvantage with these methods is that they still require substantial effort in moving sand or some other material in a quantity sufficient to stabilize the umbrella. In each case, the umbrella support apparatus is not secured into the ground. Accordingly, they rely solely on the weight of the sand or other material. Furthermore, they are not stable in that they can be blown over in modest winds. Also, they do not accommodate methods for angling the umbrella to compensate for the movement of the sun. In addition, these devices limit the user to locations where the ground material can be easily manipulated, thereby ruling out use at most parks or at other venues where there is no sand.
U.S. Pat. No. 6,964,277 to Naber entitled “Tie-Down for a Beach Umbrella” describes yet another method, which includes tethers that are attached to the umbrella shaft or canopy and that are then anchored in the sand. While these type of devices are successful at anchoring the canopy of the umbrella, they typically need to be attached to the canopy (or shaft) each time they are used and do not store with the umbrella when not in use.
Accordingly, there is a need for an umbrella support system that overcomes one or more of the problems described above.
The present invention is designed to address at least one of the aforementioned problems and/or meet at least one of the aforementioned needs.
An umbrella anchoring system and method are disclosed. In one embodiment, the umbrella anchoring system is used to support an umbrella having a shaft and a canopy. The umbrella anchoring system includes a center tube oriented vertically for receiving the shaft of the umbrella. A plurality of ribs are attached to the center tube at a proximal end. The plurality of ribs, when deployed, are oriented in a plane perpendicular to the center tube. A plurality of table leg assemblies correspond with the plurality of ribs. A proximal end of each of the plurality of table leg assemblies is correspondingly connected to a distal end of each of the plurality of ribs. Each of the plurality of table leg assemblies is substantially parallel to the center tube when deployed. Each of the plurality of table leg assemblies includes a moveable ground stake that is driven into the ground to secure the plurality of table leg assemblies in place relative to the ground.
In one configuration, the present invention includes an integrated umbrella support frame system, a table top system and an umbrella canopy tethering system.
In certain embodiments, the umbrella anchoring system: (1) will support or hold erect a beach umbrella on various surfaces and climatic conditions; (2) requires no tools and little effort to erect; (3) does not rely on moving amounts of sand or other material to weight down the apparatus; (4) is easily adjustable to allow for angling the umbrella shaft to compensate for movement of the sun; (5) can be used on a variety of surfaces and is not limited to use on sand; (6) can accept a variety of umbrella shaft sizes; (7) provides a flexible but firm table top surface area with beverage holders and an area for placing food and other items; (8) provides storage compartments for food, drink, ice, keys, electrical devices and other items; (9) is portable and light weight, such that it can be folded, stored and transported easily with the umbrella; and, (10) provides additional support to the upper portion or canopy of the umbrella in the case of higher than normal winds.
In one embodiment, the umbrella anchoring system has a central tube or cylinder with an attached support frame system that folds and unfolds into a table with an accompanying table top system that includes beverage holders and storage compartments.
In one embodiment, the table leg assemblies of the support frame system each include a sliding ground stake within, that extends and is able to penetrate various ground surfaces, such as sand, grass and soil sufficiently, such that the umbrella anchoring system is virtually locked to the ground without the necessity of adding sand or other material to it hold down, which makes it less likely to be tipped over by wind or other forces.
In one embodiment, the canopy tethering system, which is attached to the umbrella canopy, is adjustable. Specifically, the tether ground stake can be deployed when needed and stored in its ground stake receptacle, which may be attached to the canopy when not in use, such that the canopy tethering system does not need to be attached and detached with each use.
Other objects, features, embodiments and advantages of the invention will be apparent from the following specification taken in conjunction with the following drawings.
While this invention is susceptible of embodiments in many different forms, there are shown in the drawings and will herein be described in detail, preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspects of the invention to the embodiments illustrated.

In one embodiment, the center tube 152 is approximately 14 to 18 inches in length and approximately two inches in diameter to receive an umbrella center shaft 122. The diameter is such that it will accommodate a wide variety of beach umbrella center shafts. The bottom of the center tube has a solid plastic or metal collar (hub stopper) 164 that is stationary and will stop the runner hub 162 from advancing beyond the bottom of the center tube 152.
In one embodiment, there is an opening 166 along the top outside edge of the center tube 152 approximately three inches in length by one and a half inches wide. The purpose of this opening 166 (cutaway) is to permit the umbrella center shaft 122 to be set at an angle to allow for different positions of the umbrella, as depicted by the phantom lines in

The ribs 154 are attached to the hub flanges 172 with fasteners 174 (three are labeled in
In one embodiment, the ribs 154 and stretchers 156 are made of aluminum or other such material that is lightweight and strong. The ribs 154 are attached at the other end (away from the top hub 158) to a universal joint 176, which serves to connect the rib 154 to the table leg assembly 178 and the stretcher 156 in a hinged fashion so that the support frame assembly 110 can be opened and closed (compare
In one embodiment, the universal joint 50 is made of plastic, ABS, aluminum or other such materials that are lightweight and strong. It has an opening on one end (not labeled) to receive and attach to the rib 154. All attachments to the universal joint 176 of the various parts of the support frame system 110 can be accomplished by, but not limited to, bolt, rivet or glue.
There are two sets of flanges 182, 184 on the underside of the universal joint 176 for attaching the stretchers 156 and table leg assembly 178, respectively. The universal joint flange 184 for the table leg assembly 178 has an indentation on the inner portion of the flanges 184 so that they lock or hold the table leg assembly 178 in place, when in open position and the table leg assembly 184 is extended at 90 degrees.
The stretchers 156 are attached at the universal joint flange 182 just below the connection between the rib 154 and universal joint 176, forming a hinge between the rib 154 and stretcher 156 through the universal joint 176. The stretchers 156 are in turn attached at the other end to the runner hub 162, which is similar in design to the top hub 158, but it is larger in circumference to allow it to slide freely up and down the center tube 152. The runner hub 162 has additional supports 186 (see

It should be understood that there several other ways of attaching the table top system 130 to the support frame system 110. For example, at the outermost end of the universal joints 176, a tension flange may be provided at a 90 degree angle for the purpose of stretching the table top taut when in open position. There is a hole on the outer, lower portion of the tension flange to accommodate an attachment point for a clasp, or snap button to secure the removable table top.
Other methods of securing the tabletop system 130 include, but are not limited to Velcro strips sewn in to the tabletop system, with the opposite Velcro material attached to the universal joint 176. The material of the table top is flexible and strong, such that in the closed (stowed/transport) position, it folds in tight to the center tube 152 for easy storage.

Other embodiments of the table leg tube 214 and the table leg foot cap 224 are possible. For example,
Referring again to
The top end has a handle 222 to allow the operator to push the ground stake 216 into the ground (along with removing the stake 216 from the ground). The handle 222 will be formed by a bend in the ground stake 216, so that the handle is generally perpendicular to the main shaft of the ground stake 216. In one embodiment, the ground stakes are made of steel or similar material allowing them to be of a smaller diameter than typical plastic tent pegs, which permits them to easily penetrate the ground surface. The ground stakes are pushed into the ground surface by hand or in some cases by some other force (e.g., a hammer). The ground stake handle 222 can be rotated 45 degrees to facilitate insertion into the ground and can be rotated out of the way once desired penetration is reached, so that they are tucked under the table top system 130.
Referring to
The locking mechanism 234 and ground stake 216 can move freely up and down the table leg tube 214 and rotate 45 degrees such that the channel 218 in the table leg tube 214 permits. When the ground stake 216 is pressed down, the pointed end penetrates the ground surface. When the cam lever 246 is pressed down, it applies pressure on the collar block 242 which pulls the ground stake collar 238 closer to the collar block 242, thereby squeezing the wall of the table leg tube 214 between the two. This causes the locking mechanism 234 and ground stake 216 to hold secure in place to the table leg tube 214, thereby locking it in place and firmly securing the entire apparatus to the ground.
When all four ground stakes 216 are secure in the ground surface and the table leg tubes 214 are locked to the ground stakes, the umbrella anchoring system 100 (support frame system 110) is then firmly and securely fastened to the ground. The umbrella center shaft 122 is also firmly attached to the center tube 152. The downward force of the ground stake 216 on the table leg tube 214 applies force downward on the end of the ribs 154 which creates a downward force on the stretchers 156 which is directed to the base of the center tube 152 where the runner hub 162 meets the hub stopper 164. The downward pull on the ribs 154 also applies an outward force at four points on the top hub 158, where the ribs are attached at 90 degree intervals, and which firmly secures and stabilizes the top of the center tube 152. All of these factors combine to create a very secure and solid center tube 152 for receiving and stabilizing the shaft of an umbrella 122. This creates a second anchoring point for the umbrella shaft 122 where the umbrella shaft passes through the center of the top hub 158, through the center tube 152 and through to the ground surface (first anchor point). This increases the stability of the umbrella exponentially over standard methods, as the center tube 152 is made of a strong material and does not rely on the density or weight of the surface material for the support of the umbrella shaft.
The umbrella shaft 122 can be secured on an angle by placing the umbrella shaft 122 through the opening in the center tube 166 (or, alternatively, through an opening in top hub 158 or a combination of the top hub 158 and opening in the center tube 166) at an angle and not down the main shaft of the center tube 152 as shown in
A canopy tethering system 140 is shown in
In one embodiment, the adjustable strap 264 is directed through a ring attached to the ground stake receptacle and attached to an adjustable strap buckle which is in turn attached to the adjustable strap, thereby forming a loop. The adjustable strap buckle can be moved forward and back, thereby lengthening and shortening the adjustable strap.
The ground stake receptacle 266 serves to house the ground spike 268 when not in use and forms a secure connection between the adjustable strap 264 and the high tension string 272. The ground spike receptacle 266 has a ring 276 on each end connected by a strap 278 looped around each ring 276. Attached along the length of the strap 278 is connected a bag (ground stake receptacle 266) made of canvas, polyester or other such material that is flexible and strong, big enough to house the ground stake 268 and high tension string 272. The ground stake receptacle 266 is closed on the end where it is attached to the adjustable strap 264 and is open at the end attached to the high tension string 272. In one embodiment, the open end will have a snap button (not shown) attached for the purpose of closing the ground stake receptacle 266, so as to secure the ground stake 268. Two carabiner clips 282 are attached to the ground stake receptacle 266 for the purpose of securing the ground stake receptacle 266 to the canopy ribs 284 of the umbrella 120 between the juncture of the umbrella ribs and stretchers and the outermost edge of the umbrella canopy 124.
To deploy the canopy tethering system 140, the ground stake 268 is taken from the ground stake receptacle 266 and extended to the ground surface, where the ground stake 268 is pushed into the ground surface to a suitable depth, such that it is able to withstand tension from the attached high tension string 272. The high tension string 272 extends from the ground stake 268 and is attached to the ring 276 on the ground stake receptacle 266. The ground spike receptacle 266 is attached to the umbrella canopy ribs 284 and is also secured to the umbrella shaft 122 through its connection to the adjustable strap 264. This serves to anchor the umbrella shaft 122, restricting its movement in the direction that the wind is blowing and serves to anchor the umbrella canopy at the point where the ground spike receptacle 266 is attached, preventing it from buckling in the same direction of the wind. When not deployed, the high tension string 272 is wrapped around the ground stake 268 and placed in the ground stake receptacle 266 for storage.
