No. 62/026,633, filed Jul. 19, 2014, entitled “Compact Flip-resistant Umbrella,” the entirety of both are incorporated by reference in their entirety.
BACKGROUND OF THE INVENTION By “umbrella”, we mean not only a portable or fixed device having a canopy protecting a person or object from rain or sun, but also a device that impedes the flow of some object from the area on the outside of the canopy to the area below the canopy.
Since the appearance of the first descriptions of umbrellas—often to protect kings and warriors from the sun—the basic principles of how the umbrella operates have remain largely unchanged: rigid members support a canopy to divert water away off the canopy and away from the operator. Early descriptions also show mechanisms relying on a user's (or other mechanical) power to extend a semi-rigid or rigid frame for the umbrella. Many more recent umbrella inventions relate to these mechanisms, and have several inherent problems.
The first weakness occurs in windy conditions in which the umbrella may flip inside out and needs to be un-flipped by hand. One primary disadvantage of existing technology is that, when the umbrella is fully extended, the furthest edges of the umbrella have little force against the wind. Often, the umbrellas will collapse in large gusts of wind, exposing the user to the elements.
A second weakness of existing technology is that the frame is constructed of rigid members connected at joints. Not only are the members subject to bending and snapping, the joints are a weak point and tend to weaken over time.
Further problems of existing technology occur when an umbrella is closed after use. Because rain will shed down the closed canopy, the user may be soaked by water from the top of the umbrella.
Yet another problem exists with opening of the umbrella. It is difficult to hold the umbrella high enough to avoid disturbing people near-by. Because of how a normal umbrella functions, one would need an area at least the size of an opened umbrella around the user in order to open it. This could be an issue in a crowd.

SUMMARY OF THE INVENTION The current invention relies on the principle that, when a longer flexible object is made to join at each end of a shorter object, the longer object will bend and the shorter object will stretch to its taut position. The shorter object will be referred to in the current invention as the “restraining member”, “restraining line”, or “line”. The longer flexible object will be referred to as a “rib”.
Using this principle, the current invention shows a number of practical embodiments of the principle when applied to a device (e.g., umbrellas and/or umbrella-like structures) to protect an object (e.g., a person, people, a geographic area, etc.) from an article (e.g., rain, sun rays, other weather conditions, flying debris, etc.) received from above the device. In some embodiments, the device may be a personal device designed to protect a smaller object or group of objects such one or two people. However, in other embodiments, the device may be design to protect a larger object or group of objects such as, for example, a group of people, a sidewalk, a deck or yard of a house.
In one embodiment, the device utilizes a set of shorter objects or restraining lines and a set of flexible, sturdy longer objects or ribs stored within a tube or other container. In some embodiments, the ribs may be affixed only to an interior sliding base within the tube, where interior sliding base may be attached to an exterior sliding ring on an external portion of the tube. Each restraining line of the set may be affixed near each end of a rib. For instance, at a first end of the rib extending outward from the tube and at a second end of the rib within the tube affixed to the interior sliding base. In some embodiments, when a user pushes on the exterior sliding ring, the ribs travel toward the outside of the tube. When the ribs have been fully extended, the length of each restraining line is shorter than the length of each rib when measured from the tube exit to the point where each restraining line attaches to the first end of each rib. Each rib may thereby be forced to bend due to the tension created by the length of the restraining lines. The form of each rib of the device may further be guided by a canopy (e.g., fabric, vinyl, etc.) attached to the ribs. In some embodiments, the canopy (or any other canopy described herein) may be configured with solar cells, photovoltaic cells, and/or solar thermal collectors in order to allow for captured energy to be converted to electricity or heat.
Since the ribs and restraining lines in the current invention are flexible and continuous, each may behave dynamically against wind force. As a tension increases against the line, that line's full test-strength will work against the wind. In some embodiments, since the device described herein has no joints on the restraining line or ribs, the device is may not be susceptible to weakness as are devices having joints. By attaching each restraining line at a location not at a rib's outer edge, the rib would flex in in response to wind force at the attachment point, thereby deflecting that force.
In some embodiments, where the restraining lines are stretchable (but less stretchable than the force exerted by the bent ribs), then the restraining lines will stretch when wind pressure works against the canopy from underneath the device. This may allow the canopy to flex in response to wind force, but also provide a means for the device to be returned to its normal open state.
In another embodiment, the restraining lines may be replaced by a continuous piece of stretchable inner fabric distinct from the outer canopy. The radius of this inner fabric provides the shorter object to work against the longer ribs, but may more quickly be dispersed when the wind blows against the inner fabric. In fact, the inner fabric can be constructed so that the entire device will flex in response to wind force is such a way as to “spill” the wind quickly. Once the wind force is spilled, the umbrella may be brought back to its normal open state by the normal tension between the inner fabric and the outer canopy and the ribs supporting it.
Yet another embodiment describe that the ribs of the device may telescope as the device is opened, allowing for a more compact closed position for the device. Similarly, a mechanism allowing ribs to open in a hinged or butterfly fashion permits a compact closed position so that the device is more easily transported. Each of these mechanisms incorporate the use of flexible ribs—(e.g., carbon fiber-reinforced polymer, graphene, etc.)—bending into shape through the use of restraining lines. As the user moves the flexible ribs out of the tube, by manipulating restraining lines attached to the tube, and/or by manipulating a sliding mechanism of the tube, the device may take the desired umbrella shape due to the bending of the flexible ribs.
Other embodiments involves partially opened devices—during precipitation events (e.g., rain, snow, etc.)—which may collect water into a reservoir for use (e.g., watering plant, purification, agriculture, etc.) while the fully opened device—during excessive sun—may protect a surface from parching. In some embodiments, the device may include a surface for collecting energy (e.g., light rays) from the sun absorbed by the canopy. For instance, a flexible canopy may include or be constructed with solar cells, photovoltaic cells, and/or solar thermal collectors in order to allow for captured energy to be converted to electricity or heat.
The term “about” or “approximate” as used in context of describing example devices for protecting an object from precipitation or other articles is to be construed to include a reasonable margin of error that would be acceptable and/or known in the art.
As used herein, the terms “a,” “an,” and “the” mean one or more.
As used herein, the terms “comprising,” “comprises,” and “comprise” are open-ended transition terms used to transition from a subject recited before the term to one or more elements recited after the term, where the element or elements listed after the transition term are not necessarily the only elements that make up the subject.
As used herein, the terms “having,” “has,” “contain,” “including,” “includes,” “include,” and “have” have the same open-ended meaning as “comprising,” “comprises,” and “comprise” provided above.
The present description may use numerical ranges to quantify certain parameters relating to the invention. It should be understood that when numerical ranges are provided, such ranges are to be construed as providing literal support for claim limitations that only recite the lower value of the range as well as claim limitations that only recite the upper value of the range. For example, a disclosed numerical range of 24 to 36 provides literal support for a claim reciting “greater than 24” (with no upper bounds) and a claim reciting “less than 36” (with no lower bounds) and provides literal support for and includes the end points of 24 and 36.
DETAILED DESCRIPTION OF THE INVENTION In some embodiment, the disclosed device uses several flexible ribs which are forced to bend by shorter restraining members in order to support the canopy. Each rib may be constrained by a filament line, an inner fabric, or any other object able to restrain the rib. Because the length of the restraining member (or radius of the inner fabric) is less than the length of the flexible rib, the rib is forced to arch. The size of the arch is controlled by the difference between the length of the restraining member (or radius of the fabric) and the length of the rib and their points of attachment or meeting. FIGS. 1a-3c show the progression from closed to open states of this personal umbrella device embodiment using lines, whereas FIG. 12 shows the lines replaced by an inner fabric.
It is envisioned that several methods could be utilized to operate the flexible ribs in the device. For example, the mechanism would consist of a filament, rope, string or wire connected to the end of a normally straight flexible member. By pulling on the string that is threaded through loops secured at one or more location on the flexible member it would cause the flexible member to bend (FIG. 6). By adjusting the stiffness of the flexible members, the location and number of loops, and how far the strings are pulled, a multitude of device shapes are possible. There is also potential for different groups of ribs in the device to be controlled independently, thereby becoming infinitely configurable by the user. If sensors and motors are added to the device, it could allow the device to adjust to the wind as well as being flip-proof.
As is evident, there are a number of variations to this line and flexible rib method. Yet another variation is, rather than using loops, a shaped fabric sleeve can be used. The flexible rib would be fixed inside a shaped sleeve, and as the string is pulled the flexible rib would bend to follow the shape of the sleeve.
Another variation could have the string threaded through a number of rigid hinged containers which would pivot at the hinges when tension is applied to the string.
Yet another variation is using an inner stretchable fabric of a radius similar to that of the lines, and thereby replacing the lines as the mechanism to exert force on the ribs as they are pushed to an open position. This inner fabric can then act as a means to spill air that can be caught under the device. Not only is the angle of the inner fabric with respect to the wind less than that of the canopy, the combination of canopy and inner stretchable fabric can flex in its entirety with respect to the wind force.
A further possible application of the invention is to provide an easy-to-use shade for a back-packer, as shown in FIG. 13.
Another embodiment of the invention, as shown in FIG. 14, has agricultural uses. In its partially opened state, the device could collect rain water during rains and store this in a vessel for later use. At other times, the device in its fully opened state could protect crops and gardens from harsh sunlight while water from the vessel is used to irrigate these plants.
In another embodiment—allowing for a more compact closed state for the device—instead of rigid members pushing against each other to support the canopy, the invention uses several flexible rib pairs which bend to support the canopy.
In a closed position utilizing telescoping ribs, the present invention shows a plurality of rib pairs consisting of an upper rib contained within a hollow lower rib. As the device is opened, the upper rib is extracted from the lower rib. A coupling sleeve slides over the juncture of the upper and lower ribs to create a rigid unit. The drawings show an embodiment of this mechanism, with lines positioned such that the opening motion extracts the upper ribs from the lower ribs. The bases of the lower ribs are attached to a sliding base.
Utilizing a butterfly mechanism, the present invention also shows a plurality of rib pairs consisting of an upper rib and lower rib which are coupled by a tension-spring butterfly-type component during the action of opening the device. This component can be as simple as a tension spring, or may be any of several other devices, 2 of which are shown in the drawings.
The coupling of the upper and lower ribs of each rib pair may be accomplished in any of several ways. Two possible methods of many are shown in the drawings. In one, a coupling sleeve slides over the juncture of the upper and lower ribs. In another, such as shown in FIG. 16, the lower rib has a pointed end that inserts into a receptacle end of the upper rib.
Each upper and lower rib pair is constrained by a line or an inner fabric. Because the length of the line (or radius of the inner fabric) is less than the length of the flexible rib pair, the rib pair is forced to arch. The size of the arch is controlled by the difference between the length of the line (or radius of the fabric) and the length of the extended rib pair and their points of attachment or meeting.
Yet another embodiment of the invention incorporates hinged between the paired members such that, as the ribs are ejected from the container, the lines pivot the outer ribs into an extended position, as shown in FIGS. 21a-21c.
As is evident, there are a number of variations to these line and flexible rib-pair methods. Yet another variation is to run the line through two hollow ribs comprising a telescoping rib pair. This line would act to extend the upper rib as well as to move the coupling sleeve into place.

In this embodiment, the ribs (20) may be configured to exit the container (5) at different locations along the container, resulting in a vast variety of different possibilities for the shape of the device.
In some embodiments, the container may channels or slot down the side of the container and configured to interact with a specific rib (20) of the set of flexible ribs. In this embodiment, when the inner base (15) is moved toward the top end of the container, the first end of the ribs may be pushed out of the top of the container. The restraining lines (40) may be attached to various points on the container (5). For instance, each restraining line (40) may be attached at a location on the slot of the container (5). As shown in FIG. 10, then the ribs (20) are extended outside the container (5), the varying length of each restraining line (40 and the varying exit point from the container (5) of each rib (20) may result in a device having an asymmetrical shape.
FIG. 11 FIG. 11 shows a cross-section view of the device in which the lines (40) feed through numerous grommet-like holes (30) integrated with the ribs (20), thereby keeping the lines (40) closer to each rib (20). In some instance, this may create more headroom under the device. Each line is secured at 2 locations: one at the end of a rib and the other at some place integrated with the container (5).
While FIG. 11 illustrates four grommets on each rib, any number of grommets may be used. For instance, for longer ribs more grommets may be used to hold the restraining line. As described above, grommets (30) may be integrated as part of the rib or may be separated rings secured to each rib.
FIG. 12 FIG. 12 shows a cross-section view of the device in which the restraining lines are substituted with an inner stretchable fabric (55) connected to the ribs (20) at various points (56). In some embodiments, the inner fabric may be configured to cover the entire under surface of the ribs when the device is in an open state. The inner fabric may be secured on its outer periphery to either the ribs or the outer canopy (not shown), which its middle is integrated with the container (5).
FIGS. 13a and 13b FIGS. 13a and 13b show cross-sectional views of the device embodied within a backpack. In some embodiments, the device may be integrated with the backpack. However, in other embodiments, the device may be removably attached to the backpack.

In some embodiments, the device may have 2 to 3 ribs in order to protect a wearer of the backpack from rain or sun. As in the earlier embodiments, a first end of each rib may be attached to an inner base (15) within with the container (5). The inner base has a drawstring (155) available for the user to pull. When the user pulls the drawstring, the inner base (15) forces the ribs (20) and canopy out of the container.
FIG. 13b shows the device in its open state. The first end of the ribs (20) have been forced downward by the lines (40) and the canopy is pulled taut over the ribs when the ribs (20) are fully arced.
FIGS. 14a and 14b FIGS. 14a and 14b show cross-sectional views of the device embodied as a water collection device with a reservoir (170). In this embodiments, the ribs of the device are not pulled downward such that the device does not open to a position that sheds water from the canopy.
FIG. 14a shows the device in an initial state having a container (5) containing multiple flexible ribs (20), a first end of each rib attached to an inner base (15) which is within the container (5). Each rib has a restraining line (40) attached near the rib's end furthest from the base and each line attached then to the interior drum (120). Canopy (50) may be attached to the ends of the ribs at the canopy's periphery. The canopy may have a hole in the center above the container (5). In some embodiments, when the crank (130) is manipulated the lines (40) may be drawn or wrapped around the drum (12) which may move the inner base (15) along the track (150) via a screwing mechanism (160) as described above. As this occurs, the ribs (20) may be pulled out by the lines. A reservoir (170) is used in tandem with the device to collect water caught by the canopy and drained through the center hole on the canopy and inner portion of the container.
FIG. 14b shows the water collection device in its open state. The first end of the ribs (20) have been forced out but not downward by the restraining lines (40) which have been wound partially around the interior drum (120) and by the inner base (15) pushed upwards by the screwing mechanism (160), and the canopy (50) is pulled taut over the ribs when the ribs (20) are extended. Water falling on the structure is directed by the canopy (50) into the reservoir (170) through the center hole in the canopy and then down through the container (5).

FIG. 21a shows the device in an initial closed state having a container (5) containing a plurality of flexible rib pairs having an inner-rib (211) and outer rib (210), connected with hinge (215), with one end of the inner-rib (211) attached to an inner base (15). The inner-rib (211) and outer-rib (212) are further connected at the hinge point by a tension-spring-like mechanism (220) which, in the closed state, forces outer-rib (210) against the outside of container (5). Each outer-rib (210) has a fixed-length or slightly-stretchable line (40) attached to the outer-rib's end closest to the base with the other end of the line attaching to the base of the container (5). The inner base (15) is attached to an outer sliding ring (10).
FIG. 21b shows the device as it is opened. By sliding the sliding ring (10) along the container (5), the attached inner base (15) forces the multiple inner-ribs (211) out of the container (5). The fixed-length or slightly-stretchable lines (40), attached at the end of the outer-ribs (210), force the outer-ribs to pivot at the hinge (215), thereby extending the outer-ribs (210) away from the container.
With the outer-ribs (210) fully extended, the restraining force of the fixed-length or slightly-stretchable lines (40) bend the inner-ribs (211) into the umbrella shape, as shown in FIG. 21c.
When closing the umbrella, the tension spring's (220) forces the outer-ribs (210) back against the container (5) as the force of the lines (40) diminishes and eventually evaporates.
