DETAILED DESCRIPTION

Overview

[0020] The basic umbrella design has enjoyed a long history of success, however, a major drawback has perennially been the need to hold the unit with one hand. In this way, it deprives the user of full dexterity and drastically limits the situations in which umbrellas are conveniently used. Users have long desired an effective and convenient method with which to gain the benefits of an umbrella without having to hold it with one's hands.

[0021] Many attempts at hands-free umbrella systems employ harnesses or holders worn on a user's body, which a basic umbrella is received, but have multiple drawbacks for real world usage of the umbrella. For example, the hands-free umbrella systems can employ a holder mounted to a vest, a backpack, a torso harness, or a belt-based apparatus worn about the waist. Each of these attempts at hands-free umbrella systems are based on a fundamental flaw that require the user to spend most of their time standing straight. As soon as the user bends or crouches for any reason, the canopy is mispositioned and fails to provide proper coverage of the user. These systems are based on a narrow view of the general activity level of users, which results in poor coverage of the user. Moreover, the drawbacks of these systems are compounded by the need for bulky harnesses, obligatory backpacks, or restrictive belts. Furthermore, the time for conversion between stowage and deployment of the canopy is hindered by the need to remove or reposition the holder or for the user to perform some tricky maneuvers behind their back. The unpopularity of such systems is evident by their poor showing in the market.

[0022] Other attempts at hands-free umbrella systems employ an umbrella supported on the user's head by a hat or harness worn on the head. While a hat-based umbrella design can have a more centered position to protect a user from weather conditions, the design has large inherent flaws. One such flaw is the difficulty to manage the hat in windy conditions, where the stability of the hat is heavily dependent on how tight the hat grips the user's head. Wearing any hat too tightly can cause headaches, skin damage, or other condition, where a large hat that is being buffeted by the wind can compound these issues. Additionally, hat-based umbrella designs have a further hindrance of not being useful if not being worn on the head. For instance, the hat-based umbrella design does not provide the conveniences of a stand-alone umbrella having a shaft that the user can hold in their hand to support the canopy overhead, which is a traditional umbrella feature that is highly useful.

[0023] Accordingly, the present disclosure is directed, at least in part, to systems and methods for a portable weather canopy that includes a shaft that transitions between at least two states, where a first state provides flexible shaft portions that can be worn on a user's body or wrapped about an object and a second state reversibly couples the flexible shaft portions to provide a rigid shaft to support the canopy. The first state of the portable weather canopy can provide a configuration that wraps about a portion of the user's body to maintain the canopy above the user's head while providing a hands-free and stable wearing experience. The second state of the portable weather canopy can provide a configuration that supports the canopy relative to the rigid shaft, which can provide a traditional umbrella experience.

[0024] In an aspect, a collapsible, portable weather canopy includes a foldable canopy and a collapsible shaft configured to physically support the foldable canopy relative to a user or an object. The collapsible shaft generally includes at least a shaft portion, a first flexible shaft body extension, a second flexible shaft body extension, and a handle. The shaft can include a first end and a second end, with the first end configured to couple to the foldable canopy, and with the second end including a mounting site. Each of the first flexible shaft body extension and the second flexible shaft body extension can be coupled to the mounting site. For example, the first flexible shaft body extension can include a first plurality of links extending from the mounting site and the second flexible shaft body extension can include a second plurality of links extending from the mounting site, where the second plurality of links can be configured to releasably couple with the first plurality of links. The links can include, for example, a protrusion that extends from a body portion, where the protrusion from one link can interface with a body portion of another link to provide a rigid shaft portion. In aspects, the links of the first plurality of links are coupled together via a cable that extends between the links and the shaft.

[0025] The first plurality of links and the second plurality of links can releasably couple between at least a first shaft configuration and a second shaft configuration, where the first shaft configuration couples at least a portion of each of the first plurality of links and the second plurality of links to form a rigid shaft, and where the second shaft configuration at least a portion of the first plurality of links is separated from the second plurality of links to provide flexible extension portions configured to wrap about a portion of a body of a user or an object to stabilize the foldable canopy relative to the body of the user or the object, such as in a hands-free manner.

[0026] The handle can be slidably coupled to each of the first flexible shaft body extension and the second flexible shaft body extension to provide separation or coupling therebetween to transition the extensions between the first and second shaft configurations. For example, the handle is generally configured to slide toward the shaft to separate the first plurality of links from the second plurality of links (e.g., to provide the second shaft configuration) and to slide away from the shaft to couple the first plurality of links with the second plurality of links (e.g., to provide the first shaft configuration). The handle can define a shape to contour to a neck or shoulder region of a user, with the first and second flexible shaft body extensions passing through the handle to wrap about the user to stably support the canopy above the user's head when the collapsible shaft adopts the second shaft configuration via positioning of the handle relative to the shaft.

Example Implementations

[0027] Referring to FIGS. 1-10, a system 100 for providing a portable weather canopy that includes a collapsible shaft that is convertible between a rigid shaft configuration, configured for hand-held use, and a wrapping configuration, configured to be wrapped about a user's body or an environmental object, is shown in accordance with example embodiments of the present disclosure. The system 100 is shown in FIG. 1 as generally including a foldable canopy 102, a collapsible shaft 104, and a handle 106. The handle 106 is slidably coupled to the collapsible shaft 104 to transition the system 100 between the rigid shaft configuration (e.g., shown in FIGS. 1-3) and the wrapping configuration (e.g., shown in FIG. 9), with a transitional state therebetween shown in FIG. 8. The system 100 is shown including cables 108 that flexibly couple portions of the collapsible shaft 104 together to permit flexible portions to extend from the collapsible shaft 104 to wrap about a portion of a user, an environmental object, or combinations thereof, while supporting the foldable canopy 102 in an open configuration. The system 100 is also shown including a support stand 110 pivotably coupled to the handle 106 that can physically support the system 100 or portions thereof, such as by bracing against an environmental object, an environmental surface, a portion of a user, an object worn by a user, or combinations thereof.

[0028] In implementations, an example of which is shown in FIG. 2, the foldable canopy 102 includes a plurality of ribs 200 coupled to a canopy material 202 that forms the outer structure for the foldable canopy 102. The foldable canopy 102 is shown including a runner 204 coupled to the plurality of ribs 200 via a plurality of stretchers 206. The runner 204 defines an aperture through which the collapsible shaft 104 can pass as the runner 204 is slid relative towards or away from the handle 106 to retract or extend the stretchers 206 as the runner 204 slides along the collapsible shaft 104. In implementations, the runner 204 is permitted to slide along the collapsible shaft 104 when the collapsible shaft 104 is in the rigid configuration and is impeded from sliding along the collapsible shaft 104 by a flexible portion of the collapsible shaft 104 when the collapsible shaft 104 is in the wrapping configuration (or transitioning thereto). While the system 100 is shown with the foldable canopy 102 as a foldable umbrella canopy being supported by the collapsible shaft 104, the disclosure is not limited to such a canopy and can include different tool implements supported by the collapsible shaft 104 including, but not limited to, rigid canopies, flexible canopies, rigid umbrellas, flexible umbrellas, rigid parasols, flexible parasols, or other tool implements.

[0029] Example components of the collapsible shaft 104 are described with reference to FIGS. 3 through 6. The collapsible shaft 104 is shown including a first flexible shaft body extension 300A, a second flexible shaft body extension 300B, and a shaft section that is configured to coupled to each of the first flexible shaft body extension 300A and the second flexible shaft body extension 300B (e.g., via one or more of the cables 108). The first flexible shaft body extension 300A and the second flexible shaft body extension 300B each include a plurality of links 302 coupled together, such as through cables 108, mechanical hinges, or other mechanical coupling. For example, the first flexible shaft body extension 300A is shown including a first plurality of links 302A and the second flexible shaft body extension 300B is shown including a second plurality of links 302A. The links 302 of each flexible shaft body extension releasably couple with links 302 of another flexible shaft body extension to transition the collapsible shaft 104 between the rigid shaft configuration and the wrapping configuration (e.g., upon lateral movement of the handle 106 along the collapsible shaft 104). In implementations, the links 302 include faceted exterior surfaces to provide an octagonal rigid shaft, however the disclosure is not limited to such shapes of the links 302 and corresponding shaft 104 and can include any other shape for the rigid shaft. While the collapsible shaft 104 is described with reference to two flexible shaft body extensions, the disclosure is not limited to two flexible shaft body extensions and can include more than two flexible shaft body extensions, such as three flexible shaft body extensions, four flexible shaft body extensions, more than four flexible shaft body extensions, and so forth, that releasably couple links of the respective flexible shaft body portions to transition between the rigid shaft configuration and the wrapping configuration.

[0030] Each link 302 is generally shaped such that, when combined with other links to form a flexible shaft body extension and held together via mechanical linkages (e.g., via cables 108), the flexible shaft body extension will resist collapse of the collapsible shaft 104 when combined with interlocking mates from an adjacent flexible shaft body extension. For example, a link 302 is shown in FIG. 4A having a body portion 400 and a protrusion 402 extending from the body portion 400. The protrusion 402 of a link 302 is structured to interface with a protrusion 402 of at least one other link 302 to provide a rigid shaft composed of multiple links 300 that are longitudinally and laterally stabilized through the structural interfaces between links 302. For example, FIG. 4 shows the protrusion 402A of a link 302A of the first flexible shaft body extension 300A interfacing with two protrusions 402B of two different links 302B coupled together forming a portion of the second flexible shaft body extension 300B. In implementations, the protrusion 402 of one link 302 is also configured to interface with at least one body portion 400 of another link 302. For example, the protrusion 402A is shown in FIG. 3 as interfacing with the two protrusions 402B of two different links 302B and with the body portions 400B of the two different links 302B. In implementations, the links 302 of one flexible shaft body extension are coupled together via the cables 108. For example, the link 302 is shown in FIG. 4B with the body portion 400 defining an aperture 404 therethrough to receive the cable 108 through the link 302 for introduction into the body portion 400 of an adjoining link 302. The links 302 can define any number of apertures to receive any number of cables or other mechanical linkages as desired to flexibly couple links of one flexible shaft body extension together. The link 302 is shown with the aperture 404 positioned substantially vertically through the body portion 400, however the aperture 404 could have any other configuration through the link 302 to provide a pathway through which the cable or other mechanical linkage is directed to flexibly couple links of one flexible shaft body extension together.

[0031] In implementations, the links 302 can include surface features that facilitate lateral and/or longitudinal stability of the collapsible shaft 104 as the links 302 are interfaced together. For example, referring to FIG. 4A, the link 302 is shown with the body portion 400 defining a ridge 406 extending from the body portion 400 adjacent the protrusion 402, with the link 302 in FIG. 4B is shown with the body portion 400 defining a first ridge 406 on a top portion of the link 302 and defining a second ridge 406 on a bottom portion of the link 302. The link 302 is also shown including a groove 408 on a surface of the protrusion 402 opposite the body portion 400. The ridge 406 of one link 302 is structured to be at least partially received by a groove 408 of another link 302, whereas the groove 408 of one link is structured to at least partially receive a ridge 406 of another link 302. Where a link includes multiple ridges 406, each ridge can interface with a groove 408 of a different link 302 to provide lateral stability between links of different flexible shaft body extensions. For example, referring to FIG. 5, one link 302A of the first flexible shaft body extension 300A and two links (302B, 302C) of the second flexible shaft body extension 300B are shown. The link 302A includes the ridge 406A which is configured to be received in the groove 408B of the link 302B, whereas the ridge 406B of the link 302B is configured to be received in the groove 408A of the link 302A. Similarly, the link 302C includes the ridge 406C which is configured to be received in the groove 408A of the link 302A (e.g., simultaneously with the ridge 406B), whereas the second ridge 406AA of the link 302A (e.g., on the bottom of the link 302A) is configured to be received in the groove 408C of the link 302C. The shapes of the protrusions 402, ridges 406, and grooves 408 provide for a rigid shaft configuration that can be separated through sliding action of the handle 106 that acts to separate the flexible shaft body extensions from each other.

[0032] Referring to FIG. 6, the shaft section of the collapsible shaft 104 is shown including a substantially rigid shaft 600. The shaft 600 includes a first end 602 and a second end 604 opposite the first end 602. The first end 602 is structured to couple with the foldable canopy 102 (e.g., to mount the foldable canopy 102 to the collapsible shaft 104). The second end 604 includes a mounting site 606 that is structured to couple to each of the flexible shaft body extensions (e.g., to the first flexible shaft body extension 300A and the second flexible shaft body extension 300B). For example, the shaft 600 can define one or more shaft apertures 608 extending from the first end 602 to the second end 604 (e.g., opening at the mounting site 606) to receive a cable 108 from adjoining links 302 and into the shaft 600 to secure the first flexible shaft body extension 300A and the second flexible shaft body extension 300B to the shaft 600 at the mounting site 600. In implementations, the mounting site 600 includes contours that match the outline of at least a portion of the protrusion 402 of an adjoining link to provide lateral and longitudinal stability to the connection between the shaft 600 and the flexible shaft body extensions. In implementations, the mounting site 606 includes a groove 610 configured to receive a ridge 406 of an adjoining link 302 and includes a ridge 612 configured to be received into a groove 408 of the adjoining link 302. In implementations, the runner 204 is configured to move in a direction from the first end 602 to the second end 604 and past the mounting site 606 when the collapsible shaft 104 is in the rigid configuration, and is prohibited from moving past the mounting site 606 when the collapsible shaft 104 is in the wrapping configuration.

[0033] Referring to FIGS. 7A and 7B, an example of the handle 106 is shown. The handle 106 generally facilitates the slidable coupling and decoupling of the flexible shaft body extensions by sliding the handle along collapsible shaft 104 (e.g., towards or away from the shaft 600). For example, the handle 106 includes a handle body 700 that defines a shaft aperture 702 structured to receive the collapsible shaft 104 with the first flexible shaft body extension 300A and the second flexible shaft body extension 300B coupled together in the rigid configuration. The handle body 700 also defines a first extension aperture 704 and a second extension aperture 706, where the first extension aperture 704 is configured to receive the first flexible shaft body extension 300A following separation of the links 302A from the links 302B of the second flexible shaft body extension 300B and where the second extension aperture 706 is configured to receive the second flexible shaft body extension 300B following separation of the links 302B from the links 302A of the first flexible shaft body extension 300A. Other apertures can be defined by the handle body 700 if additional flexible shaft body extensions are included in the system 100. An example separation process of the handle 700 separating links 302A of the first flexible shaft body extension 300A from links 302B of the second flexible shaft body extension 300B is shown in FIG. 8, whereas FIG. 9 shows the system 100 in the wrapping configuration, with the handle 700 positioned adjacent the shaft 600 having fully separated the links 302A of the first flexible shaft body extension 300A from links 302B of the second flexible shaft body extension 300B. With the flexible shaft body extensions separated, the respective extensions can be wrapped about portions of a user's body (e.g., as shown in FIG. 11), an environmental object, or the like, to support the foldable canopy 102 above the user, above the environmental object, or the like. In implementations, the system 100 includes straps or other coupling devices (e.g., attached to the handle 106, to the cables 108, or to another structure of the system 100) to provide additional stability during wrapping of the flexible shaft body extensions.

[0034] Referring to FIG. 10, the support stand 110 is shown pivotably coupled to the handle 106, where the support stand 110 can rotate being a position coupled to the rigid shaft (e.g., shown in FIG. 1) to a position that can physically support the system 100 or portions thereof, by bracing against an environmental object, an environmental surface, a portion of a user, an object worn by a user, or combinations thereof (e.g., as shown in FIG. 10). For instance, the support stand 110 can resist a backwards leaning motion of the foldable canopy 102 when the system 100 is secured to the user or the like.
