DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] The preferred embodiments of the present invention will now be described with reference to the drawings. Identical elements in the various figures are identified with the same reference numerals.

[0021] Reference will now be made in detail to each embodiment of the present invention. Such embodiments are provided by way of explanation of the present invention, which is not intended to be limited thereto. In fact, those of ordinary skill in the art may appreciate upon reading the present specification and viewing the present drawings that various modifications and variations can be made thereto.

[0022] As seen in FIG. 1, an anti-inversion apparatus 10 for an umbrella can include a removable clasp 4 which can be made of at least one movable appendage 14 and at least one matching appendage 15 configured to couple to the movable appendage 14. The movable appendage 14 may include a strap and the matching appendage 15 may include a hook. The movable appendage 14 may interact with the matching appendage 15 at multiple positions (such as through a variety of holes on the movable appendage 14) such that different types of umbrellas can be used with the invention. The appendages can be flexible, and be made of rubber or plastic. The plastics specifically include polyethylene terephthalate (PET), polyethylene (PE), high-density polyethylene, polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), low-density polyethylene (LDPE), polypropylene (PP), polystyrene (PS), high impact polystyrene (HIPS) and polycarbonate (PC), or any combination thereof.

[0023] The removable clasp 4 can be coupled to a housing 1. The housing 1 can be generally round and coupled to the removable clasp 4 with a fastener 5 (see FIG. 3). The housing 1 can contain a circular cavity 35 (as shown in FIG. 3). The cavity 35 can contain a rotatable spool 36 and spring 37. The cavity 35 can also contain other spools and springs. The spool 36 can be coupled to one end of a linking member 2. The inside of the housing 1 and the inner components can be seen in FIG. 3. The housing 1 should also have an opening 16 through which the linking member 2 can be pulled though. The openings 16 should be large enough to allow the linking member 2 to be pulled through easily. The openings should be smooth and not abrasive such that prolonged use of pulling the linking member 2 back and forth does not abrade and lead to tearing of the linking member 2.

[0024] The linking member 2 can be a cord or string with a ring 8 on the end that can be pulled out of the housing 1. The linking member 2 should be made of a strong but flexible material that will not snap during wind gusts but that swill also not etch out over time. The linking member 2 can include a stopper 9 (as shown in FIG. 2) on the outer ends to prevent the members from fully retracting into the housing 1. The stopper 9 can be of various shapes but should be larger than the opening 16. The stopper 9 can be interchangeable and can be used to add style, color, and some individuality to the anti-inversion apparatus 10.

[0025] The ring 8 may be coupled to the outer end of the linking member 2. The ring 8 should be large enough such that it can easily fit over the umbrella ends 11 (as seen in FIG. 4), but also small enough such that the ring 8 holds the umbrella ends 1 when a gust of wind hits the umbrella 12 (shown in FIG. 4). The ring 8 can be removable and interchangeable with other style of rings. The ring 8 can be changed out in order to fit over a specific umbrella end 11. The ring 8 can also be made of a flexible material, possibly rubber or plastic. FIG. 2 shows a close up of the ring 8 coupled with the umbrella end 11.

[0026] As seen in FIG. 1, it is beneficial to have the linking member 2 extend through the opening 16 in the housing 1 with the opening 16. The housing 1 may include a number of the openings 16 and the linking members 2. For example, another linking member may extend through another opening in the housing 1. The openings (16 and another) may be separated by approximately 135 degrees and approximately 225 degrees from each other. Approximately defines an angle or other angle(s) formed within several degrees plus or minus of 135 degrees to 225 degrees. This allows the linking members (2 and another) to be attached in various configurations to the ends (11 and another).

[0027] Since there is no umbrella standard about the spacing and density of the umbrella ends 11, the direction of the openings (16 and others), the lips of the openings (16 and others) and the flexibility of the linking members (2 and others) allow the device 10 to be paired with any umbrella. In another embodiment, the outer ends of the linking members (2 and others) can be split into multiple ends with multiple rings, each of the rings attaching to an individual umbrella tip. This configuration would add even more structure to the umbrella during windy conditions, and prevent unnecessary space consumption by the linking member 2 underneath the umbrella 12.

[0028] As further seen in FIG. 4, the anti-inversion apparatus 10 can be placed on a central portion of the umbrella 12 preferably on a shaft portion or directly on a runner 20 on the shaft of the umbrella 12. The benefit of placing the anti-inversion apparatus on the runner 20 is that the anti-inversion apparatus 10 never has to be removed. As the runner 20 moves up and down, the linking member 2 is automatically retracted and pulled out, while the umbrella is opened and closed.

[0029] The anti-inversion apparatus 10 can be attached to any thickness and shape of the runner 20. Attributes of the appendages such as flexibility and stretch-ability allow the anti-inversion apparatus 10 to be mounted and locked to multiple placements associated with the runner 20. The position of the linking member 2 in relation to the umbrella end 11 allows the linking member 2 to pull the end 11 at such an angle that the linking member 2 bends the end 11 slightly inwards and the flapping of the end 11 is not exacerbated during a wind gust. The anti-inversion apparatus 10 bolster or replace a function of pre-installed rods in preventing an inversion of the umbrella 12 because the pre-installed rods are not attached to the end 11 and do not control or hold the end 11 with sufficient stability during forceful events such as a gust or a wind.

[0030] As seen in FIG. 5, the anti-inversion apparatus 10 may be placed on the shaft or the runner 20 on the shaft of the umbrella 12 (similar to as seen in FIG. 4). However, a radius of the umbrella 12 may be shorter (or longer) than the linking member 2 connecting the anti-inversion apparatus 10 to the end 11. In such a scenario, a length adjuster 22 may be utilized to adjust a length of the linking member 2. In an example scenario, an excess portion of the linking member 2 (such as a string) may be wound on the length adjuster 22. As such, a length of the linking member 2 may be adjusted to match the radius of the umbrella 12. The linking member 2 may be connected to the end 11 through the length adjuster 22. As a result, an inversion of the umbrella 12 may be prevented during an application of a variety of forces such as wind and others.

[0031] Finally, the anti-inversion apparatus 10 and all the embodiments mentioned above can be part of a system or kit with an existing umbrella 12. The kit can be supplied such that it can be retrofitted onto any existing umbrella 12 and the system can be supplied such that it can provided as one piece with the umbrella.

[0032] Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made only by way of illustration and that numerous changes in the details of construction and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention.
