WIND RESISTANT UMBRELLA

Abstract

An inversion resistant umbrella. The inversion resistant umbrella is configured to minimize the likelihood of a protective canopy from turning inside out, thereby minimizing the risk of damage to the umbrella. The inversion resistant umbrella comprises a canopy sized and shaped to protect a user from one or more environmental elements, such as rain. Attached to, or integrally formed from the canopy, is an inversion resistant member. The inversion resistant member, or sleeve, is configured to act as a valve to allow air to travel through the interior portion of the umbrella and out through at least a portion of the canopy. As such, when a gust of wind catches the canopy from underneath, the inversion resistant member extends upwardly and outwardly to allow for the air to pass through.

DETAILED DESCRIPTION OF THE INVENTION

[0025] While the present invention is susceptible of embodiment in various forms, there is shown in the drawings and will hereinafter be described a presently preferred, albeit not limiting, embodiment with the understanding that the present disclosure is to be considered an exemplification of the present invention and is not intended to limit the invention to the specific embodiments illustrated.

[0026] Referring to FIGS. 1-3, an inversion resistant protective device, referred to as an inversion resistant umbrella 10, is shown. In general, the inversion resistant umbrella 10 is constructed and arranged to protect one or more individuals from outdoor elements, such as rain or sunshine, while minimizing the risk of changes in structural configuration during high wind periods. The inversion resistant umbrella 10 comprises a canopy 12 sized and shaped to protect, i.e. cover, a user from direct contact with environmental elements, i.e. rain, when placed over his/her head. The canopy 12 can be constructed of any material. Preferably, the material, such as nylon, can withstand rain, is impermeable to water, dries quickly, and is foldable.

[0027] The inversion resistant umbrella 10 further comprises a shaft 14 having a first end 16 (terminating in cap 17) positioned at or near the canopy 12, and a second opposing end 18 positioned at a distance from the canopy 12. The second opposing end 18 preferably contains a handle 20 sized and shaped to be grabbed and held by a user's hand. A plurality of ribs 22 runs underneath the canopy 12. The ribs 22 are preferably made of a thin steel or other metal material, and help maintain the configuration of the canopy 12 when in the open position. One or more stretchers 24 connect the ribs 22 to the shaft 14 via a runner 26 and provide a mechanism to expand the canopy 12 from a closed position to an open position. The runner 26 is configured to move or slide along the shaft 14, thereby extending (open, protective position) or retracting (closed, non-protective position) the canopy 12. The shaft 14 may contain catch springs 28 to aid in opening and closing the inversion resistant umbrella.

[0028] Referring to FIG. 5, a standard umbrella 100 in an inverted position is illustrated. In this orientation, the canopy 112 is flipped inside out, exposing the internal components, the ribs 114, and the stretchers 116. This orientation typically results from wind gusts that get underneath the umbrella 100. In this position, the user may try to flip the canopy 112 back to its original position. While this may be an option, many times one or more of the components are destroyed. For example, during the sudden inversion, the ribs 114 or the stretchers 116 may be bent or disfigured. Alternatively, the canopy 112 may become ripped or torn. Even if the components are still intact and usable, the user would be required to get the umbrella back in its original position, thereby exposing him/her to the elements.

[0029] To prevent inversion, or flipping inside out, the inversion resistant umbrella 10 comprises an inversion preventing valve, illustrated herein as a sleeve 30. The sleeve 30 comprises a first, open top end 32, a second, open bottom end 34, and a main body 36 therebetween. The first, open top end 32 may be tapered inwardly (from dotted lines 37A and 37B. The tapered end may be slight, with diameter 39 of the open end being about 1-5% smaller than a diameter 41 of the main body 36. The tapered end allows the sleeve 30 to maintain its shape when filed with air, thus lowering the wind resistance by reducing turbulence. The sleeve 30 may be integrally formed with the canopy 12, or may be constructed independently and separately attached. The bottom end 34, preferably, is secured to, or extends from a canopy opening 38 (see FIGS. 1 and 3), which is formed at the top portion (first end 16 of the shaft 14) of the canopy 12. The canopy opening 38 may be centrally positioned within the canopy 12. The length of the sleeve 30 is preferably sufficient to maintain a position flat on top of the canopy and covering the canopy opening 38.

[0030] In use, the inversion resistant umbrella 10 is configured to prevent inversion, or having the canopy 12 flip inside out, through the traversal of the sleeve 30 between a first non-extended position, see FIG. 2, and a second extended position, see FIG. 3. In the non-extended position, the sleeve 30 is configured to rest, preferably lying flat, against the outer surface 40 of the canopy 12. As shown in FIG. 2, as wind currents flow over the canopy 12, see arrows 40A, 40B, 40C, a low pressure zone is created above the canopy 12. In addition to this low pressure zone, gravity keeps the sleeve lying flat against the canopy 12. In the situation in which a strong gust of wind catches the canopy 12 from underneath, see arrows 42A and 42B in FIG. 3, the sleeve 30 extends upwardly and orients away from the canopy 12. The wind travels into the interior section 44 of the canopy 12, see FIG. 4, through the canopy opening 38 and into the sleeve 30. The air exits out of the sleeve 30, see arrows 46A and 46B through the sleeve opening 48. A plurality of triangular flanges 51 (also seen on FIG. 1) are sown into or attached to seams at the inner most frame attachment points. The inclusion of the triangular flanges force the extended canopy 12 to assume an ideal funnel shape, thereby helping to minimize turbulence.

[0031] In addition to acting as a valve for allowing directional air flow through the canopy 12, thereby preventing inversion of the canopy 12, the sleeve 30 can be used as a protective covering for the inversion resistant umbrella 10. Referring to FIG. 6, the inversion resistant umbrella 10 is shown in the closed configuration, in which the canopy 12 does not extend outwardly and radially relative to the shaft 14. In this configuration, the sleeve 30 extends above the closed canopy 12. Folding the sleeve 30 back against the closed canopy 12 in the direction of arrows 50A and 50B allows the sleeve 30 to fully enclose the closed canopy 12, see FIG. 7. As such, the sleeve 30 may be sized sufficiently to fully cover the inversion resistant umbrella 10 when the canopy 12 is in the closed position. Alternatively, the sleeve 30 may be sized and shaped to wrap around the exterior of the closed umbrella canopy 12. A strap 52 having a first fastening member 54, illustrated as one portion of VELCRO, either a loop fastener or hook fastener, and a second fastening member 56, illustrates a second portion of the VELCRO, either a loop fastener or hook fastener FIG. 8 illustrates the inversion resistant umbrella 10 shown in a closed position, with the canopy wrapped together and held by the strap 52
