Drop stitch construction is commonly used for inflatables, such as paddle boards, to form flat surfaces. With drop stitch construction, top and bottom sheets of fabric are joined together along parallel planes using many equal length stitches to thereby form a core. This core can be coated in one or more thin layers of PVC to make it air and water impermeable while retaining its flexibility. A sidewall can also be connected between the top and bottom sheets of fabric to form an enclosed, inflatable article. Because the two sheets of fabric are joined together by equal length stiches, the top and bottom sheets will remain flat even when the core is inflated to high pressures. Other techniques also exist for creating inflatables with flat surfaces such as internal baffles spanning from the top sheet to the bottom sheet. These methods of construction typically limit the inflatable to a single flat configuration when inflated.
The present invention is generally directed to inflatables having one or more flat segments that are configured to form one or more bends and to techniques for forming and maintaining such bends. The flat segments of the inflatables could be formed using any technique such as drop stitch. One or more bends may be maintained in one or more flat segments of an inflatable such as to create a ladder and a slide. A variety of bend maintaining components can be used to maintain the one or more bends.
An inflatable configured in accordance with one or more embodiments of the present invention can be selectively converted between a mat configuration and a slide configuration. When in the mat configuration, the inflatable can be placed on water to allow individuals to stand and play on the inflatable. When in the slide configuration, the inflatable can be secured to a boat or other structure overtop the water to allow individuals to slide into the water. The inflatable can be configured to enable a bend to be maintained between a slide end and a ladder end to thereby transition the inflatable from the mat configuration to the slide configuration.
In some embodiments, multiple bends could be maintained in one or more flat segments of an inflatable. For example, two bends could be maintained in a flat segment of an inflatable to create a ladder end, a horizontal portion and a slide end.
In some embodiments, the present invention may be implemented as an inflatable that includes a flat segment having a top, a bottom and a sidewall that extends between the top and the bottom, and one or more bend maintaining components for maintaining one or more bends.
In some embodiments, the inflatable may include one or more additional flat segments each having a top, a bottom and a sidewall that extends between the top and the bottom.
In some embodiments, the one or more bend maintaining components are removable to cause the flat segment to remain flat.
In some embodiments, the one or more bend maintaining components comprise one or more bend maintaining straps for maintaining the one or more bends in the flat segment.
In some embodiments, the one or more bend maintaining components comprise one or more angle bars in the sidewall for maintaining the one or more bends in the flat segment.
In some embodiments, the one or more bend maintaining components comprise one or more sheets of material for maintaining the one or more bends in the flat segment.
In some embodiments, the one or more sheets of material have a triangular shape.
In some embodiments, the inflatable may include two or more flat segments, and the one or more bend maintaining components may be one or more wedges that connect flat segments to each other to create and angle between the connected flat segments.
In some embodiments, the one or more bend maintaining components maintain more than one bend in the flat segment.
In some embodiments, the inflatable may include one or more bend locating components.
In some embodiments, the one or more bend locating components may include one or more bend locating straps secured to the bottom of the flat segment and positioned at an interface between a first portion of the flat segment and a second portion of the flat segment, and one or more bend locating rings secured to the bottom of the flat segment and positioned at the interface opposite the one or more bend locating straps. The one or more bend locating straps and the one or more bend locating rings may be configured to locate a bend in the flat segment of the inflatable along the interface.
In some embodiments, the inflatable may include stiffeners that are secured to the bottom of the flat segment and positioned on opposite sides of at least one of the one or more bends.
In some embodiments, the stiffeners may include multiple pairs of stiffeners that are spaced apart to create at least one gap for accommodating a fold line.
In some embodiments, the inflatable may include one or more tie off points secured to the bottom of the flat segment.
In some embodiments, the inflatable may include one or more sidewall protectors positioned on or in the sidewall of the flat segment at a location of at least one of the one or more bends.
In some embodiments, the one or more bends convert the flat segment of the inflatable into a slide.
In some embodiments, the inflatable may include a pad secured to the top, the pad including one or more ridges to enable the pad to function as a ladder.
In some embodiments, the present invention may be implemented as an inflatable that includes a top, a bottom, a sidewall that extends between the top and the bottom and at least one bend maintaining component that maintains a first bend. The first bend creates a slide portion on one side of the bend. In some embodiments, the first bend also creates a ladder portion on the opposite side of the bend from the slide portion.
In some embodiments, the present invention may be implemented as an inflatable that includes a top, a bottom, a sidewall that extends between the top and the bottom, one or more bend locating components for locating one or more bends, and one or more bend maintaining components for maintaining the one or more bends.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter.
Understanding that these drawings depict only typical embodiments of the invention and are not therefore to be considered limiting of its scope, the invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
The term “segment” will be used to reference an individual walled off portion of an inflatable. A flat segment would therefore be a segment that is constructed to be flat when inflated. The term “bend” will be used to reference either an angle formed in a flat segment or a change in angle between two adjacent flat segments of an inflatable. Embodiments of the present invention will be described primarily in the context of an inflatable having a single flat segment that can be converted between a mat and a slide. However, embodiments of the present invention encompass a variety of inflatables having any reasonable number of flat segments and possibly non-flat segments that can be configured to maintain one or more bends in one or more flat segments or between adjacent flat segments to selectively form other toys or structures.
In the context of embodiments of the present invention, an inflatable may have one or more inflatable flat segments that include internal supports that constrain a top and bottom of the flat segment to be substantially flat and parallel to one another. A flat segment of an inflatable may commonly be formed using drop stitch construction, but other techniques exist and are encompassed by embodiments of the present invention. In some embodiments, in addition to one or more flat segments, an inflatable could have one or more segments that are not configured to be flat. In some embodiments, all segments of an inflatable, whether or not the segments are flat, could be inflated together, while in other embodiments, at least one of the segments of an inflatable could be separately inflated.
The term “bend locating component” should be construed as any suitable structure by which a bend is located in a flat segment of an inflatable. A bend locating component typically functions to cause a bend to be formed in a particular location of the flat segment of the inflatable while the inflatable is being inflated. One or more bend locating components may be used to locate a bend. Examples of bend locating components include rings, straps, a zipper, etc.
The term “bend maintaining component” should be construed as any suitable structure by which a bend is maintained in a flat segment of an inflatable. A bend maintaining component functions to cause a bend to be maintained after the inflatable is inflated including during use/play. One or more bend maintaining components may be used to maintain a bend. Examples of bend maintaining components include straps, angle bars, an angled sheet of material, a wedge, etc.
Inflatable 100 can be viewed as having a slide end 100a and a ladder end 100b. Ladder end 100b can include a pad 110 that can function as a ladder when inflatable 100 is in the slide configuration. In some embodiments, the top/outer surface of top 101 can be smooth and un-textured to minimize its coefficient of friction when wet. Inflatable 100 may include a valve (e.g., a Halkey-Roberts valve) positioned anywhere in top 101, sidewall 102 or bottom 103.
In some embodiments, bend locating components can be included on bottom 103 to cause a bend to be formed in the proper location when the flat segment of inflatable 100 is inflated. For example, one or more bend locating straps 204 and corresponding bend locating rings 205 can be secured to bottom 103 on opposing sides of the interface between slide end 100a and ladder end 100b and can function to locate a bend at the interface. For example, as is better shown in
In some embodiments, bend maintaining components can be included on bottom 103 to maintain a bend in inflatable 100 after inflatable 100 is inflated such as during play. For example, bottom 103 may include one or more sets of bend maintaining rings 202a and 202b that are positioned on opposing sides of the interface between slide end 100a and ladder end 100b and corresponding bend maintaining straps 203. In some embodiments, each of bend maintaining rings 202a and 202b can be spaced equal distances from the interface such that, when ladder end 100b is oriented substantially perpendicular to slide end 100a, bend maintaining straps 203 will be positioned at approximately a 45-degree angle relative to bottom 103. However, in other embodiments, supporting rings 202a and 202b may be spaced at unequal distances from the interface. Of course, bend maintaining straps 203 or any other bend maintaining components could be used to create a bend of any angle between ladder end 100b and slide end 100a.
When in the mat configuration, bend maintaining straps 203 can be connected between bend maintaining rings 202b for storage. To transition to the slide configuration, bend maintaining straps 203 can be connected between pairs of bend maintaining rings 202a and 202b as shown in
Forming the bend in the flat segment of inflatable 100 can cause added stress on sidewall 102. Accordingly, in some embodiments, a sidewall protector 207 may be secured (e.g., glued or welded) to sidewall 102 overtop the portions of sidewall 102 where the bend is formed. In some embodiments, sidewall protectors 207 may be secured to sidewall 102 prior to securing tape 104 overtop the seams. In such embodiments, tape 104 may be secured overtop sidewall protectors 207.
Bottom 103 may also include one or more tie off points 206 which can be used to secure slide end 100a to a boat or other structure. In the depicted example, three sets of three tie off points 206 are positioned across the width of bottom 103. Each tie off point 206 may accommodate a rope or other mechanism. Spacing tie off points 206 across slide end 100a facilitates securing inflatable 100 to a variety of boat configurations including a variety of cleat locations.
Although the above description relates to a mat slide, embodiments of the present invention extend to other types of inflatables. For example, a bottom of any inflatable having one or more flat segments could include any or all of stiffeners 201, bend inducing strap(s) 204, bend inducing ring(s) 205, supporting strap(s) 203 and supporting ring(s) 202a, 202b for inducing and maintaining a straight bend at a desired location of the inflatable.
Embodiments of the present invention also encompass methods for locating and/or maintaining a bend in a flat segment of an inflatable. For example, to locate a bend in a flat segment of an inflatable, such as but not limited to a mat slide, an individual could insert a bend inducing strap through a bend inducing ring that is positioned on an opposite side of an interface between two portions of the flat segment of the inflatable. The individual could then pull the bend inducing strap back on top of itself to thereby cause a bend to be located at the interface when the flat segment of the inflatable is inflated. In some embodiments, regardless of whether a bend locating component is used, the individual may connect a bend maintaining strap between a pair of bend maintaining rings that are positioned on opposite sides of the interface to thereby maintain the bend while the inflatable is in use.
The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description.
