SUMMARY OF THE INVENTION

The invention relates to an expandable drift sock system that includes an expandable drift sock having a plurality of expansion sections configured around the circumference of the cylindrical sleeve, each having a first and second expansion portion detachably attached to each other by a section coupler. The first and second expansion portions each have an outer extension and fold portion that folds back to join with an inner extension that extends between the fold portions of the first and second expansion portions. Flaps are configured to fold over each expansion portion to hold the expansion portion in a folded configuration and to prevent water from flowing in between the folds that may produce force the stowed expansion portion to open.

The invention relates to an expandable drift sock system including an expandable drift sock having a plurality of expansion sections configured around the circumference of the cylindrical sleeve having a first and second expansion portion detachably attached to each other by a section coupler and flaps that fold over the configuration and prevent water from flowing between folds of the expansion portions.

An expandable drift sock system comprises an expandable drift sock that includes a cylindrical sleeve with a plurality of expansion sections configured to move from a stowed configuration to an expanded configuration. The cylindrical sleeve has an outer perimeter and extends from an inlet end to an outlet end. The inlet end has an inlet opening for receiving a flow of water therein, and the outlet end has an outlet end opening for said flow of water to flow out from the cylindrical sleeve. The cylindrical sleeve may be a conical sleeve, conical in shape, wherein the inlet end or inlet end opening has a diameter that is larger than the outlet end or outlet end opening diameter of the outlet end. The ratio of the inlet diameter 24 to the outlet diameter may be 1.5:1 or more, about 2:1 or more, about 3:1 or more, about 5:1 or more in stowed configuration and the inlet end diameter may be expanded by expanding one or more of the expansion sections. The diameter ratio of the inlet diameter to the outlet diameter when in a fully expanded configuration with each of the plurality of expansion sections expanded may be about 1:5:1 or more, about 2:1 or more, about 3:1 or more, about 5:1 or more, about 8:1 or more, about 10:1 or more and any range between and including the ratios provided. Also, the expansion ratio of the inlet diameter in a stowed configuration to the inlet diameter when in a fully expanded configuration may be about 1.5:1 or more, about 2:1 or more, about 2.5:1 or more, about 3:1 or more, about 5:1 or more and any range between and including the ratios provided.

The expandable drift sock may have an inlet end or inlet end opening diameter that can changed from a stowed configuration to an expanded configuration by opening each of the plurality of expansion sections, wherein the inlet expansion ratio of the inlet diameter from a fully expanded configuration to a fully stowed configuration may be about 1.5:1 or more, about 2:1 or more, about 2.5:1 or more, about 3:1 or more. When the fold portions of the expansion portions is about the same length as the outer extension of said expansion portions then the inlet expansion ratio may be about 3:1. The increase in the inlet diameter may be increased or incrementally by opening one or a portion of the expansion sections as desired to provide the proper drift rate in a current.

An expandable drift sock may have a plurality of expansion sections, such as two or more, three or more, four or more, five or more, six or more or even about eight or more and any range between and including the number of expansion sections provided.

The cylindrical sleeve may be a conical sleeve that has a length of about 0.5 m or more, about 0.75 m or more, about 1 m or more, about 1.5 m or more, about 2 m or more, about 2.5 m or more and any range between and including the lengths provided. The diameter of the inlet end of the cylindrical sleeve in a fully stowed configuration may be about 0.5 m or more, about 0.75 m or more, about 1.0 m or more, about 1.25 m or more, about 1.5 m or more, about 2.0 m or more, about 2.5 m or more and any range between and including the values provided. The fully expanded diameter of the inlet end may be any of the ratios provided herein. The length and diameter of the cylindrical sleeve may be chosen based on the size of the boat and the speed of the current.

Each expansion section has a first expansion portion and a second expansion portion having a first fold portion and second fold portion, respectively, that extends from a respective first outer extension and second outer extension to an inner extension. An expansion section can be changed from a stowed configuration with the section coupler coupling the first expansion portion to the second expansion portion with the first coupler component attached to the second coupler component. The section coupler may be a zipper, having a coupler interface or slider having a pull tab to move the slider along zipper teeth, wherein a first series of zipper teeth extend along the first expansion portion and a second series of zipper teeth extend along the second expansion portion. A zipper may be a more durable and secure means of retaining the first expansion portion to the second expansion portion, more secure than buttons, snaps or hook-and-loop fasteners.

The section coupler or zipper may extend from the inlet end along the length of the cylindrical sleeve toward the outlet end. A cuff may be configured around the outlet end and the section coupler may terminate at or proximal to this cuff. The section coupler may extend a percentage of the length of the cylindrical sleeve, such as at least 50% or more, about 75% or more, about 85% or more, about 90% or more or any range between and including the values provided.

A section coupler is configured to detachably attach the first expansion portion to the second expansion portion and may include a coupler interface that may be used to detach a first coupler component 56 to a second coupler component. The coupler interface may be a zipper slider and each of the first and second coupler components may form a zipper that can be unzipped from the inlet end down towards the outlet end of the cylindrical sleeve.

A section divider may extend between each expansion section and may be a reinforced divider having a cuff, or strip of reinforcing material, such as a fabric, extending between a first expansion section and a second expansion section. The drag straps may extend from one or more of the section dividers. A strap extends from a connected end to an extended end and an extended end coupler may couple together two or more of the straps.

Each expansion section has a first expansion portion and a second expansion portion. The first expansion portion includes an outer extension and a first fold portion that folds back on the outer extension, along the interior with respect to the outer extension. The first fold portion extends from the outer extension inward and circumferentially back toward the section divider. A seam or extension fold edge extends between the outer extension and the first fold portion. The first fold portion and outer extension may be a contiguous piece of material or fabric with the extension fold edge between these two edges. A first coupler component may extend from this extension fold edge and may be coupled to a tab to aid in coupling the first coupler component with the second coupler component. The first fold portion extends from the outer extension to the inner extension and may be folded along a first fold edge between the first fold portion and the inner extension. The first fold portion may extend inside of the outer extension, with respect to the outside surface of the cylindrical sleeve. The inner extension extends from the first fold portion to the second fold portion of the second expansion portion and again, a second fold edge may extend between the second fold portion and the inner extension. The inner extension extends from the first fold edge, or from the first fold portion to the second fold portion, and extends across the section coupler. The first fold portion and second fold portion may be a single continuous piece of material or fabric with folds between the outer extensions, and the respective fold portion and the inner extension.

The second expansion portion includes an outer extension and a second fold portion that folds back on the outer extension of the second expansion portion. The second fold portion extends from the outer extension circumferentially back toward the section divider, in an opposite circumferential direction from the first fold portion. A seam or extension fold edge extends between the outer extension and the second fold portion. A second coupler component may extend from this extension fold edge and may be coupled to a tab to aid in coupling the first coupler component with the second coupler component. The second fold portion extends from the outer extension to the inner extension and may be folded along a second fold edge between the second fold portion and the inner extension. The second fold portion may extend inside of the outer extension, with respect to the outside surface of the cylindrical sleeve.

The first and second fold portions may have a length from the inner extension to the outer extension that is a portion of the length of the respective outer extension they are coupled to and may extend a substantial portion of the length of the outer extension, which is from the extension fold edge to the section divider, such as at least 50% or this length, or about 75% of the outer extension length or more, about 90% of the outer extension length or more and any range between and including the values provided. The inner extension will have a length from the first fold edge to the second fold edge that is about the sum of the length of the first fold portion and second fold portion. When the first and second fold portions are about the length of the respective outer extensions, the length of the expansion section from the section dividers may be about tripled when the expansion section is converted from a stowed configuration to an expanded configuration. The length increase of the expansion section will be the sum of the length of each of the first and second fold portions and the length of the inner extension, about a cross-section of the cylindrical sleeve.

The fold portions and the inner extension may be retained or held in a stowed or folded configuration by flaps, wherein a flap extends from the outer extension and is detachably attached to an inner extension attachment component. The flap also has an attachment component for detachably attaching to the inner extension attachment component. The expansion sections each have a first expansion portion and second expansion portion that may be held down by the first and second flaps, respectively. A first flap and second flap are configured to extend from the outer extension and over the first expansion portion and second expansion portion, respectively. The first flap is detachably attached by a first flap attachment component, configured on an inside surface of the first flap, to the first inner extension attachment component. Likewise, the second flap is detachably attached by a second flap attachment component, to the second inner extension attachment component. The first flap attachment component may be detachably attached to an outer extension attachment component, such as an outer extension second attachment component. The outer extension may also have an outer extension first attachment component configured for detachable attachment to a folded portion attachment component.

The configuration of attachment components described herein, enables a flap to be attached to the inner extension attachment component and also the fold portion attachment component attached to an outer extension attachment component to very securely retain the expansion portion in a stowed and folded configuration with two points of retention or attachment. The section coupler provides a third type of attachment of the first expansion portion to the second expansion portion. The flap may then be detached from the inner extension attachment component and the fold portion can be detached from the outer extension attachment component to enable the expansion portion to unfold and expand with the section coupler configured in a detached configuration with the first coupler component detached from the second coupler component. Also, the flap may be attached to the interior surface of the outer extension with the flap attachment component detachably attached to the outer extension attachment component. This will hold the flap out of the way for the expansion portion to expand. The first and second inner extension attachment components may be a single attachment component that extends across the inner extension, wherein a first portion on a first end is configured for the first flap to detachably attach to and a second portion on the opposing end is configured for the second flap to detachably attach to.

The second expansion portion has the second flap detachably attached via the second flap attachment component attached to the outer extension second attachment component or the outer extension of the second expansion portion. The flaps may extend over the inlet end of the expansion sections or expansion portions of an expansion section prevent water from flowing between the folds or layers of the expansion portion when in a stowed configuration and this reduces stress on the expansion portion and more effectively keeps the expansion portions stowed during use.

The attachment components described herein may be snaps, buttons and preferably are hook-and-loop fastener components, one of a hook component and a loop component of the hook-and-loop fastener. The hook-and-loop attachment enables quick attachment by simple pressing the two components together and detachment by pulling or peeling the two attached portions apart.

The expandable drift sock includes a cylindrical sleeve that is a flexible sleeve that may be made out of a fabric, such as a woven fabric. The fabric may be coated with a polymer such as a urethane coating. The expansion sections may be joined together by a section divider which may be strap, a reinforcing strap and the drag straps may be coupled to the section dividers.

The inlet end 22 has an inlet diameter 24, shown in FIG. 2, that is expandable, by expanding one or more of the expansion sections 16, 16′, 16″ and 16′″. Each expansion section has a first expansion portion 60 and a second expansion portion 80 having a first fold portion and second fold portion, respectively, that extends from a respective first outer extension 62 and second outer extension 82 to an inner extension 70.

An outlet end cuff 29 may extend around the outlet end 26 and may secure the expansion sections together and strengthen the cylindrical sleeve circumferentially as the reduced diameter of the outlet end will restrict the water flow and produce radial force on the cylindrical sleeve.

As shown in FIG. 3, expansion section 16 is in an expanded configuration with the first coupler component 56 detached from the second coupler component 58; wherein the coupler interface is slid down to the outlet end 26 of the cylindrical sleeve to unzip or detach the first expansion portion 60 from the second expansion portion 80. The inlet diameter is larger in FIG. 3 than in FIG. 1 as a result of the first expansion section being in an expanded configuration.

A section coupler 50 is configured to detachably attach the first expansion portion 60 to the second expansion portion and may include a coupler interface 57 that may be used to detach a first coupler component 56 to a second coupler component 58. The coupler interface may be a zipper slider and each of the first and second coupler components may form a zipper that can be unzipped from the inlet end down towards the outlet end of the cylindrical sleeve.

A section divider 40 may extend between each expansion section and may be a reinforced divider having a cuff 42, or strip of reinforcing material, such as a fabric, extending between a first expansion section and a second expansion section. The drag straps 90 may extend from one or more of the section dividers as shown in FIG. 1. A drag strap 90 extends from a connected end 92 to an extended end 94 and an extended end coupler 96 may couple together two or more of the straps, as shown.

With reference to FIGS. 4 and 5, each expansion section 16 has a first expansion portion 60 and a second expansion portion 80. The first expansion portion 60 includes a first outer extension 62 and a first fold portion 64 that folds back on the outer extension, along the interior, or radially inward from the inside surface 28 (shown in FIG. 4) of the cylindrical sleeve 20 or the first outer extension 62. The first fold portion 64 extends from the outer extension 62 circumferentially back toward the section divider 40. A seam or extension fold edge 65 extends between the first outer extension 62 and the first fold portion 64. A first coupler component 56 may extend from this extension fold edge 65 and may be coupled to a tab to aid in coupling the first coupler component 56 with the second coupler component 58. The first fold portion extends from the first outer extension 62 to the inner extension 70 and may be folded along a first fold edge 71 between the first fold portion 64 and the inner extension 70. The first fold portion 64 may extend inside of the first outer extension 62, with respect to the outside surface 25 of the cylindrical sleeve. The inner extension 70 extends from the first fold portion 64 to the second fold portion 84 of the second expansion portion and again, a second fold edge 72 may extend between the second fold portion 84 and the inner extension 70. The inner extension 70 extends from the first fold edge 71 or from the first fold portion 64 to the second fold portion 84 and extends across the section coupler 50.

The inside surfaces 69, 89 of the first outer extension 62 and second outer extension 82 of the first expansion portion 60 and second expansion portion 80, respectively (FIG. 5), have a flap attachment component.

The second expansion portion 80 includes a second outer extension 82 and a second fold portion 84 that folds back on the second outer extension 82. The second fold portion 84 extends from the second outer extension 82 circumferentially back toward the section divider 40′, in an opposite circumferential direction from the first fold portion 64. A seam or extension fold edge 85 extends between the second outer extension 82 and the second fold portion 84. A second coupler component 58 may extend from this extension fold edge 85 and may be coupled to a tab to aid in coupling the first coupler component 56 with the second coupler component 58. The second fold portion extends from the second outer extension 82 to the inner extension 70 and may be folded along a second fold edge 72 between the second fold portion 84 and the inner extension 70. The second fold portion 84 may extend inside of the second outer extension 82, with respect to the outside surface 25 of the cylindrical sleeve.

The first and second fold portion may have a length that is a portion of the length of the respective outer extension they are coupled to and may extend a substantial portion of the length of the outer extension, which is from the extension fold edge to the section divider, or at least 50% or this length, or about 75% of the outer extension length or more, about 90% of the outer extension length or more and any range between and including the values provided. The inner extension will have a length from the first fold edge 71 to the second fold edge 72 that is about the sum of the length of the first fold portion and second fold portion. When the first and second fold portions are about the length of the respective outer extensions, the length of the expansion section from the section dividers 40, 40′ may be about tripled when the expansion section is converted from a stowed configuration to an expanded configuration. The length increase of the expansion section will be the sum of the length of each of the first and second fold portions and the length of the inner extension about a cross-section of the cylindrical sleeve.

The fold portions and the inner extension may be retained or held in a stowed or folded configuration by flaps, wherein the flap extends from the outer extension and is detachably attached to an inner extension attachment component. The flap also has an attachment component for detachably attaching to the inner extension attachment component.

As shown in FIG. 6, the expansion sections 16″ and 16′″ each have the first expansion portion and second expansion portion held down by the first and second flaps, respectively. In particular, expansion section 16″ has a first flap 73″ and second flap 74″ extending from the outer extension and over the first expansion portion 60″ and second expansion portion 80″, respectively. The first flap 73″ is detachably attached by a first flap attachment component 730, shown in FIG. 5, configured on an inside surface of the first flap, to the first inner extension attachment component 76, also shown in FIG. 5. Likewise, the second flap 74″ is detachably attached by a second flap attachment component 740, shown in FIG. 5, to the second inner extension attachment component 78 also shown in FIG. 5.

Likewise, the second outer extension 82 of the second expansion portion 80 may also have an outer extension first attachment component 81 configured for detachable attachment to a folded portion attachment component 86 shown in FIG. 4.

The configuration of attachment components described herein, enables a flap to be attached to the inner extension attachment component and also the fold portion attachment component attached to an outer extension attachment component to very securely retain the expansion portion in a stowed and folded configuration with two points of retention or attachment. The flap may then be detached from the inner extension attachment component and the fold portion can be detached from the outer extension attachment component to enable the expansion portion to unfold and expand with the section coupler configured in a detached configuration with the first coupler component 56 detached from the second coupler component 58. Also, the flap may be attached to the interior surface of the outer extension with the flap attachment component detachably attached to the outer extension attachment component. This will hold the flap out of the way for the expansion portion to expand.

As shown in FIG. 5, the second expansion portion 80 has the second flap 74 detachably attached via the second flap attachment component 740 attached to the outer extension second attachment component 83 or the second outer extension 82 of the second expansion portion 80. The first flap attachment component 730 is shown in FIG. 5 as the first flap 73 is folded away to allow the first expansion portion 60 to unfold to an expanded configuration. The flap extending over the inlet end 22 of the expansion sections or expansion portions of an expansion section prevents water from flowing between the folds or layers of the expansion portion when in a stowed configuration and this reduces stress on the expansion portion and more effectively keeps the expansion portions stowed during use.

It will be apparent to those skilled in the art that various modifications, combinations and variations can be made in the present invention without departing from the scope of the invention. Specific embodiments, features and elements described herein may be modified, and/or combined in any suitable manner. Thus, it is intended that the present invention cover the modifications, combinations and variations of this invention provided they come within the scope of the appended claims and their equivalents.
