The present disclosure relates to the field of dry recreational slides, and more particularly to portable dry recreational slides.
Recreational slides are longstanding popular attractions at playgrounds and for backyards. However, such slides typically are expensive, permanent structures that require steeply-sloped inclines in order for a user to slide thereon. Not only are such slide permanent installations, but because of the steep slope requirements it can be prohibitively expensive, and even dangerously high, to provide a slide with 10 or more feet of length. Bounce houses are portable inflatable structures that often incorporate slides. While technically portable, bounce houses typically are very heavy, requiring involvement by multiple adults in order to transport and set up the structure. Further, a source of electricity, when a plug-in outlet or a dedicated generator, is typically required. Like other dry slides, bounce houses also require steeply-sloped surfaces in order for users to readily slide with gravity, and thus must be very large in order to accommodate a slide of more than a few feet. Further, due to their size, bounces houses are only appropriate for placement only on certain types of terrain, such as relatively flat surfaces. Thus, bounce houses have important limitations in portability and location of use. Portable water slides made of elongated plastic sheeting flooded with water have proven popular and effective. However, in order for users to slide sufficiently upon the plastic sheeting, water and/or another medium (such as oils and soaps) must be used. Thus, portable water slides require access to a water source and/or other slide medium source, substantially limiting their portability. Also, user's must be willing to get wet in order to use the water slide, limiting their use to certain seasons and situations.
The present disclosure discloses aspects of a portable dry recreational slide that can be readily used in a broad range of locations, can be truly portable, in that some embodiments can be readily carried by a single person or even a child, and provides a sliding experience of ten feet or more without requiring application of water or any other slide medium.
The present disclosure presents aspects and embodiments of a portable dry recreational slide that can be stored and transported in a compacted configuration that is small and lightweight enough to be carried by a single person and even a child. The dry slide is easily converted from the compacted configuration to a deployed configuration in which it defines an elongated slide body that conforms to the shape of the underlying support surface, be it a flat, inclined and/or undulating outdoor grass or dirt surface or a hard or carpeted indoor surface, and includes a low-friction surface that enable riders to slide thereon without addition of added, temporary lubricants such as water, oil, soap or the like. Further, the dry slide can be compacted to a small volume, such as to fit within a 15″×5″ volume for a 3′×30′ sliding surface.
The slide body is made of a low-friction textile, most preferably a woven textile substrate such as a woven nylon, polyester or polyethylene with a low friction coating such as a silicone coating. The coating defines the sliding surface upon which riders may slide, and preferably has a coefficient of friction of about 0.25 or less. Most preferably the dry slide includes one or more vehicles which participants can use to distribute weight and/or which include low-friction surfaces so as to enhance the sliding experience. Vehicles can include, for example, plastic vehicles that can distribute the weight of a rider sitting or otherwise disposed thereon, and can also include a low-friction surface. Vehicles can also be made of the same or similar material as used to make the slide body. Such a textile vehicle can include a front pouch in which a rider can place their feet or which can receive a front end of a secondary vehicle, such as an inflatable vehicle, so as to take advantage of the weight-distribution and comfort of the secondary vehicle but also provide the low-friction surface of the textile vehicle.
The textile of which the slide body is made preferably is light and flexible so as to be easily reconfigured from the deployed configuration to the compacted configuration. Most preferably the textile is sufficiently light in weight so that it can be compacted, such as by being rolled up, into a size that is easily manageable, and is 10 pounds or less in weight, and even more preferably 5 pounds or less in weight for a dry slide of about 30 feet. Furthermore, in order to enhance portability, carrying straps can be integrated into the dry slide and/or a carrying bag such as a dedicated backpack can be provided so as to maintain the dry slide apparatus, including all or most components, together in one kit for easy storage and transportation.
In accordance with one embodiment the present specification provides a portable dry recreational slide apparatus, comprising a slide body that is changeable from a compacted configuration to a deployed configuration. The slide body is configured so that when it is in the deployed configuration it has a longitudinal axis and is elongated along the longitudinal axis from a start end to a finish end. The slide body comprises a flexible textile substrate comprising a woven fabric and a friction-reducing coating deposited on the textile substrate. The friction-reducing coating has a coefficient of friction less than a coefficient of friction of the textile substrate. A carrying structure is integrally formed with the slide body. The carrying structure is configurated to be accessible when the slide body is in the compacted configuration.
In some such embodiments, the slide body has a thickness less than about 0.2 mm and a density of about 150 g/m{circumflex over ( )}2 or less. In further variations, the slide body comprises a woven textile chosen from the group consisting of nylon, polyester and polyethylene. In still further variations, the friction-reducing coating comprises a silicone compound.
In some embodiments, the slide body has a length of at least 30 feet and a total weight less than 5 lb.
Some embodiments can be combined with a backpack defining a backpack space sized and configured to receive the slide body therewithin when the slide body is in the compacted configuration.
In further embodiments, a sliding surface is defined atop the friction-reducing coating, and the sliding surface has a dry coefficient of friction less than about 0.25. In further embodiments the sliding surface can have a dry coefficient of friction of about 0.21 or less.
Additional embodiments can also comprise a flexible woven textile substrate formed separately from the slide body and having a friction-reducing coating deposited on a bottom surface thereof so that the bottom surface has a dry coefficient of friction less than about 0.25. In some variations, the textile vehicle comprises a front pocket defining a front pocket space. Further variations can additionally comprise an elongated secondary vehicle having a front end configured to fit into the front pocket space of the textile vehicle and to at least partially support a rider thereon.
In yet additional embodiments, the slide body can comprise a plurality of spaced-apart anchor structures, and wherein adjacent ones of the anchor structures are configured to be attachable one to another so as to maintain the slide body in the compacted configuration.
In further embodiments, the slide body comprises a plurality of spaced-apart apertures disposed along an edge of the slide body, and the carrying structure comprises a carrying strap that is configured to fit through the spaced-apart apertures so as to maintain the slide body in the compacted configuration.
In accordance with another embodiment, the present specification discloses a portable dry recreational slide apparatus, comprising a slide body that is changeable from a compacted configuration to a deployed configuration. The slide body is configured so that when it is in the deployed configuration it has a longitudinal axis and is elongated along the longitudinal axis from a start end to a finish end. The slide body has a thickness less than about 0.2 mm and a density of about 150 g/m{circumflex over ( )}2 or less. The slide body further comprises a flexible textile substrate comprising a woven or non-woven fabric chosen from the group consisting of nylon, polyester and polyethylene, and a friction-reducing coating deposited on the textile substrate. The friction-reducing coating comprises a silicone compound and having a dry coefficient of friction less than a coefficient of friction of the textile substrate and less than about 0.25.
In accordance with another embodiment, the present specification provides a method of storing and transporting a portable dry recreational slide apparatus that has an elongated slide body made up of a flexible woven fabric substrate having a low-friction coating deposited thereon. The method comprises folding the slide body about a fold line generally parallel to its longitudinal axis and engaging a plurality of first anchoring structures spaced apart on a first edge of the slide body with a plurality of second anchoring structures spaced apart on a second edge of the slide body. The slide body can be rolled from a distal end to a proximal end. A strap structure integrated with the proximal end of the slide body can be used to secure the slide body in a fully-rolled compacted configuration. The compacted slide body can be supported using a carry portion of the strap structure.
In another variation, the slide body defines a sliding surface having a dry coefficient of friction less than about 0.25. In a further variation the slide body has a weight density between about 90-150 g/m{circumflex over ( )}2.
Yet another variation additionally comprises placing a textile vehicle comprising a flexible woven substrate having a low-friction coating deposited thereon onto the folded slide body and rolling the textile vehicle with the slide body.
A still further variation additionally comprises placing a flexible molded polymer-based vehicle onto the slide body and rolling the molded polymer-based vehicle with the slide body.
The present disclosure presents aspects and embodiments of a portable dry recreational slide that can be stored and transported in a compacted configuration that is small and lightweight enough to be carried by a single person or even a child. The dry slide is easily converted from the compacted configuration to a deployed configuration in which it defines an elongated slide body that conforms to the shape of the underlying support surface, be it a flat, inclined and/or undulating outdoor grass surface or a hard or carpeted indoor surface.
The slide body is made of a low-friction textile, most preferably a textile substrate such as a woven nylon, woven polyester or non-woven polyethylene with a low friction coating such as a silicone coating. The coating defines the sliding surface upon which riders may slide, and preferably has a coefficient of friction of about 0.25 or less. Most preferably the dry slide includes one or more vehicles which participants can use to distribute weight and/or which include low-friction surfaces so as to enhance the sliding experience. Vehicles can include, for example, plastic vehicles that can distribute the weight of a rider sitting or otherwise disposed thereon, and can also include a low-friction surface. Vehicles can also be made of the same or similar material as used to make the slide body. Such a textile vehicle can include a front pouch in which a rider can place their feet or which can receive a front end of a secondary vehicle, such as an inflatable vehicle, so as to take advantage of the weight-distribution and comfort of the secondary vehicle but also provide the low-friction surface of the textile vehicle.
The textile of which the slide body is made preferably is light and flexible so as to be easily reconfigured from the deployed configuration to the compacted configuration. Most preferably the textile is sufficiently light in weight so that it can be compacted, such as by being rolled up, into a size that is easily manageable, and is 10 pounds or less in weight. Furthermore, in order to enhance portability, carrying straps can be integrated into the dry slide and/or a carrying bag such as a dedicated backpack can be provided.

As shown in
In the illustrated embodiment, the dry slide 20 is deployed in an outdoors configuration, such as on a grassy hill, and stakes 40 help secure the dry slide 20 in place. In other situations, the dry slide 20 may be deployed indoors such as on a carpet or hard floor, in which deployment of stakes 40 is not an option. In such a situation, elongated straps 42 can be extended through the grommets 38 and can attach to furnishings or other structure so as to help hold the dry slide 20 in place. It is to be understood also that the dry slide 20 can be used without any anchoring structure.

In a preferred embodiment, the substrate comprises a textile, such as a woven textile formed of nylon or polyester fully drawn yarn 56 woven in various weaves, such as an oxford weave. The nylon or polyester textile preferably is about 0.1 mm-0.2 mm in thickness, thus providing weight reduction and cost reduction while maintaining toughness, strength and performance. The coating 54 can be applied to the woven textile, such as by an atomized spray, forming a low-friction layer. In a preferred embodiment, the coating 54 comprises a silicone compound solution having a thickness of about 0.009-0.013 mm, and more preferably about 0.011 mm. In additional embodiments, the fully drawn yarns 56 can be coated with a low-friction silicone coating prior to being woven. Another suitable substrate 52 can comprise a non-woven polyethylene blend of about 85% or more medium weight polyethylene (density of at least about 0.935 g/cm{circumflex over ( )}3) and a thickness of about 0.030-0.07 mm, also coated with a silicone. Most preferably, the slide body 22 material has a weight of about 90-150 g/m{circumflex over ( )}2. As such, the total weight of a slide body 22 about 4 feet wide and 30 feet long can be expected to be less than about 2.5-5 lb.
It is to be understood that other materials may be available, or may become available, that may be operative but may have other negative aspects. For example, high-density polyethylene, PTFE (Teflon) and fluorinated polymers may exhibit low friction, but can be unsuitable due to excessive weight and/or high cost.

It is to be understood that other types and sizes of ride vehicles can be employed. For example, foam bodyboards can be used on their own or in conjunction with a textile vehicle 60. Additional materials that are not necessarily dedicated for use with the dry-slide 20 can also be used. For example, a user may procure cardboard for use as a ride vehicle, either on its own or in conjunction with a textile vehicle 60. Some suitable ride vehicles may include boards having bottom surfaces made of high density plastics such as Surlyn® or high density polyethylene, stiff or flexible, can also be used with the dry slide 20. Further, riders can enhance their sliding experience by wearing low-friction clothing, such as clothing having components or portions made with nylon, spandex, polyester with or without fluorocarbon-based durable water repellent (DWR) or silicone coating. Such clothing can include, for example, shoes, socks, gloves, pants and knee pads.
Multiple dry slides 20 can be combined to form an extra-long dry slide. For example, the proximal end 24 of a second dry slide can be positioned—and preferably anchored—just proximal of the distal end 26 of a first dry slide 20 so that the distal end of the first dry slide 20 overlaps on top of and over the proximal end 24 of the second dry slide. As such, a rider sliding the length of the first dry slide 20 will be deposited onto the second dry slide 20, enabling continued sliding along the second dry slide. Such an arrangement preferably will cover the proximal reinforcement 44 of the second dry slide underneath the first dry slide so that it will not affect the rider's progress.

In embodiments discussed above, compacting the dry slide 20 to the compacted configuration has involved rolling up the slide from the distal end 26 to the proximal end 24. It is to be understood that, in additional embodiments, such rolling can take place without first folding the slide body 22 along a longitudinally-extending fold line, or may include multiple such folds. Also, in some variations the slide body 22 can be folded in multiple different directions rather than being rolled. In still further variations, the slide body 22 can be stuffed into a bag such as the backpack 70 without regard to rolling or folding, as with a sleeping bag.
In another embodiment, a slide body 22 can be configured for use with another dry sliding structure such as, for example, a bounce house having a slide. A slide body 22 comprising the materials discussed herein and having the low friction properties which can be selectively attached (such as via straps 42 extending through grommets 38) and detached from a slide surface of the bounce house, and particularly combined with a textile vehicle 60, can provide an improved and exciting sliding experience for the rider.
