In the illustrated embodiment, the base 102 is circular, however, the base 102 may be rectangular, oval, hexagonal, or the like. The base 102 may provide a weight and stability to the marker 100. The base 102 may be formed entirely, or in part, of a rubber or rubberized material. The material of the base 102 may be resilient to mechanical, chemical, and thermal conditions. The material of the base 102 may also provide grip relative to the ground or surface on which it is placed.
The base 102 may include a weight component or may have an inherent weight sufficient to an application of the marker 100. The base 102 may include a lip 108 forming an annular protrusion to surround the body 104 of the marker 104. The base 102 may include a recess formed on an interior of the lip 108 to receive and secure the body 104 relative to the base 102. In other embodiments, the base 102 may include other hardware or securing elements or portions. For example, the base 102 may couple to the body 104 via a zipper, snaps, hooks, buttons, clips, pins, or the like.
The base 102 may also include base coupling elements 116. In the illustrated embodiment, the base coupling elements 116 correspond to cap coupling element 118 disposed on or near the cap 106. In the illustrated embodiment, the base coupling elements 116 are loops which correspond to cap coupling element 118 in the form of toggles on or near the cap 106. The base coupling elements 116 may be coupled to the base 102 via in-molding, bonding, adhering, attachment hardware, or the like. Additionally, the base coupling elements 116 may be coupled to the body 104 at or near the base 102. As the body 104 of the marker 100 is collapsed, the base coupling elements 116 may be connected to, receive, or otherwise coupled to the cap coupling elements 118 to secure the marker 100 in a collapsed state. Other types of coupling elements 116 and 118 are described herein.
In the illustrated embodiment, the body 104 has a generally cylindrical shape. In other embodiments, the body 104 may be more or less round and may include a square geometry. The body 104 includes an outer material 110. The outer material 110 may be flexible and may be abrasion and soil resistant. The outer material 110 is flexible to allow collapse of the body 104. Additionally, flexibility in the outer material 110 may facilitate wind and impact resilience. The outer material 110 may also have fire-resistant or retardant characteristics. In some embodiments, the outer material 110 is UV resistant.
The body 104 also includes a spring element 114. In the illustrated embodiment, the spring element 114 has a helical shape and is disposed in the body 104 to support the body 104 relative to the base 102. For example, the spring element 114 may be shaped to apply a radially outward force to the body 104 to maintain a shape of the body 104. Additionally, the radially outward force may increase a retention of the body 104 at the base 102. In some embodiments, the spring element 114 also applied a longitudinal force along the body 104. The longitudinal force tends to extend the body 104 to separate the base 102 from the cap 106. This force, applied by the spring element 114, may cause a “pop-up” or “self-erecting” action in the marker 100 when released. The spring element 114 may be round or have a non-round shape such as a square helix, flat sided helix, or the like. The spring element 114 may be a single piece element or may be formed by a plurality of pieces.
In some embodiments, the spring element 114 forms a complete or near-complete circumference or closed portion. A closed portion at an end of the spring element 114 may improve retention of the spring element 114 and/or body 104 relative to the base 102. In some embodiments, a closed portion may also be formed in the spring element 114 to correspond with the cap 106. The closed portion of the spring element 114 at the cap 106 may form or match the shape of the cap 106, reduce puncture or wear of the cap 106 at an end of the spring element 114, increase a structural rigidity or strength of the cap 106, and the like.
In some embodiments, the outer material 110 has a high-contrast or bright color to increase visibility of the marker 100. The outer material 110 may include a specific characteristic or treatment to provide a visual or functional effect such as a luminescence, reflectivity, opacity, translucency, reactivity, or the like.
Additionally, the body 104 may include visibility elements 112 coupled to the outer material 110 of the body 104 to be on an exterior of the body 104. The visibility elements 112 may be reflective material, lighting elements, colored material, or the like to increase a visibility of the marker 100. In some embodiments, the visibility elements 112 are annular rings of material which encompass a circumference of the body 104. In other embodiments, the visibility elements 112 may correspond to a portion of the body 104 without extend around the circumference of the body 104. The visibility elements 112 may be one or more single pieces or may be multiple pieces. The visibility elements 112 may have multiple shapes, colors, sizes, orientations, positions, and operations (reflective, luminescent, color, etc.).
In the illustrated embodiment, the cap 106 is positioned on the body 104 to be opposite the base 102. The cap 106 may form a closure of an internal space of the body 104. In some embodiments, the cap 106 is, at least partially, releasably coupled to the body 104. For example, the cap 106 may include a zipper 120, as shown. The zipper 120 may be replace or supplemented by other mechanisms such as snaps, hook-and-look, loop-and-toggle, magnets, buttons, or the like. In the illustrated embodiment, the zipper 120 is a double zipper with two pulls oriented to face and run opposite one another. In other embodiments, the zipper 120 may be a single zipper. In the illustrated embodiment, the cap 106 is attached to the body 104 via an attachment point 122. In some embodiments, the attachment point 122 forms a non-removable connection between the cap 106 and the body 104. In other embodiments, the attachment point 122 is omitted or forms a removable connection between the cap 106 and the body 104. The attachment point 122 may take the form of a close connection, as shown which forms a portion of the interface between the body 104 and the edge of the cap 106. In other embodiments, the attachment point 122 may be a tether or other connection which is separate from the edge of the cap 106 and allows the edge of the cap 106 to be made free from the edge of the body 104 without fully separating the cap 106 from the marker 100. For example, a tether may couple a center, or other portion, of the cap 106 to a portion of the body 104 or the base 102 to secure the cap 106 to the marker 100. Such a tether or other separate connection between the cap 106 and the body 104 or other component of the marker 100 may be permanent or configured to separately disconnect from the zipper 120 or other connection mechanisms securing the cap 106 to the body 104.
The cap 106 may also include one or more of the cap closure element 118. As described in part above, the cap closure element 118 couples to the base closure element 116 to secure the marker in a collapsed or semi-collapsed state. In some embodiments, the cap closure element 118 facilitates securing of the marker 100 to another marker or other structure such as a vehicle, wall, storage structure, or the like. The cap 106 may include a single cap closure element 118 or multiple cap closure elements 118. In some embodiments, the cap closure element 118 is coupled to the body 104 or forms a portion of a connection mechanism securing the cap 106 to the body 104.
In the illustrated embodiment, the cap 106 also includes a handle 124. The handle 124 may be a flexible, rigid, or semi-rigid material or combination of materials. The handle 124 may be sized to correspond to a human hand or to a tool or mechanism for positioning, placing, or otherwise situating the marker 100. In some embodiments, the handle 124 is sewn to the cap 106. In other embodiments, the handle 124 may be attached to the cap 106 via adhesives, molding, riveting, bonding, or the like. The handle 124 may be permanently or removably attached to the cap 106. Additionally, the handle 124 may be coupled exclusively to the cap 106 or may be coupled to the body 104 or other component of the marker 100 in a mutual or exclusive manner relative to the cap 106.
In the illustrated embodiment, the handle 124 is an additional portion of material coupled to the cap 106. In other embodiments, the handle 124 may be formed in the cap 106. For example, the handle 124 may be a slip, flap, or recess formed in the cap 106 or other component of the marker 100. The handle 124 may be adjustable or reconfigurable to accommodate a corresponding use or interface requirement.
In the illustrated embodiment, the handle 124 is shown as disposed in a center of the cap 106. In other embodiments, the handle 124 may be disposed nearer an edge of the cap 106. In other embodiments, one or more handles 124 may be disposed on other portions of the marker 100. For example, one or more handles 124 may be disposed on the body 104 of the marker 100. A handle 124 may be disposed on, or formed in, the base 102 of the marker 100.
In the illustrated embodiment, the spring element 114 is secured on the body 104. In some embodiments, the spring element 114 is secured along the body 104 by retaining sleeves 202a and 202b. In some embodiments, the retaining sleeves 202a are short retaining sleeves 202a which extend over a relatively small portion of the spring element 114 to secure the spring element 114 relative to the body 104. The short retaining sleeves 202a may provide an increase in the ease of installing the spring element 114 relative to the body 104 and may reduce the time required to situate the spring element 114 relative to the body 104.
In other embodiments, the spring element 114 may be secured to the body 104 with a continuous retaining sleeve 202b. In some embodiments, the continuous sleeve 202b extends along a full length of the spring element 114 at the body 104. The continuous sleeve 202b may provide a more stable and/or uniform support for the spring element 114 along the body 104. In the illustrated embodiment, the spring element 114 is secured on the interior 200 of the marker 100 but may be secured on an exterior of the marker 100.
In the illustrated embodiment, the base 102 includes a plate 204. The plate 204 may be formed to fit within the base 102 and provide a retaining force securing the spring element 114 and/or body 104 relative to the base 102. The plate 204 may secured using hardware 206. The hardware 206 may include nuts, bolts, washers, stakes, screws, pins, clips, staples, rods, or the like. Additionally, the hardware 206 may be formed into the plate 204 or the base 102 and connected via bonding, adhesives, welds, or the like. Other removable and non-removable connections may be used to connect the base 102 and the plate 204.
In the illustrated embodiment, the plate 204 includes a lighting element 208. The lighting element 208 may be positioned in the plate 204 to provide illumination to the interior 200 of the marker 100 to improve visibility of the marker 100 in low-light conditions. In some embodiments, the lighting element 208 is self-container with a power source and illumination source in a single package. In other embodiments, the lighting element 208 may include a remote power source or connections for power supply from a remote power source. In some embodiments, the lighting element 208 may be coupled to a rechargeable power source. The lighting element 208 may include a power generator such as a solar panel, wind power generator, a hand crank, or the like. In some embodiments, the remote power source may be a power source that is external to the marker 100 such as a battery, via a vehicle connection, a utility grid, a generator, or the like.
In the illustrated embodiment, the hardware 206 is visible between the traction features 302. In some embodiments, the hardware 206 may be positioned between or within the traction feature 302. The hardware 206 may include reinforcement such as washers or other structures to improve wear resistance, pull-through strength, tensile strength, accessibility, and the like.
In some embodiments, the strap 602 is a woven material such as a nylon, canvas, polyester, or other synthetic or natural materials or composite of materials. The length of the strap 602 may be adjustable or fixed. In some embodiments, the strap 602 extends through a diameter of the base 102 to another base coupling element 116 on an opposite side of the base 102.
In the collapsed state, the marker 100 benefits from improved portability, reduced storage requirements with reduced size and improved stability with a lower center of gravity, etc. in the illustrated embodiment, the cap 106 is coupled directly to the base 102. In other embodiments, a portion of the body 104 may couple to the base 102 to secure the marker 100 in the collapsed state.
In the illustrated embodiment, the marker 100 is fully collapsed. In some embodiments, the marker 100 may be partially collapsed/extended. A partial collapse/extension may be achieved by positioning the cap coupling element 118 on the body 104 of the marker 100, by one or both of the cap coupling elements 118 and the base coupling elements 116 having a greater length, or by one or both of the cap coupling elements 118 or the base coupling elements 116 being elastic or adjustable in length. Additionally, the height of the body 104 of the marker 100 may be modified with collapsible sections of the body 104. For example, expansion segments may be formed in the body 104 which are secured using zippers, buttons, snaps, clips, hooks, and the like to shorten or lengthen the body 104.
In some embodiments, the emergency equipment 1102 may be stored in the marker 100 in a collapsed state. This facilitates use of the marker 100 as carried in a vehicle to serve as a roadside and emergency resource for occupants of the vehicle. Embodiments of the marker 100 described provide benefits for private owners, law enforcement individuals, commercial entities and drivers, and the like.
