Abstract

A recreational device comprising an elongate tube (2) of thin, flexible, gas-impermeable and substantially non-elastic plastic material, the device being adapted to be at least partially inflated, to be operatively sealed at both ends and to be capable of being bent and tied into knot-type forms when partially inflated.

Description

The present invention concerns a recreational device.
Industrial uses of large tubes of thin, flexible, gas-impermeable, non-elastic plastic material such as polyethylene, polyvinyl chloride (P.V.C.), polypropylene include use in agricultural hot-houses, packaging, and the production of bags. The raw plastic material is available in long tube-like forms having diameters of anywhere from 15 cms. to some meters and lengths of up to 20 or more meters. These tubes of industrial plastic may be translucent, typically available in a wide range of pastel colours, and are inexpensive.
The plastic material is usually very durable and can be twisted and flexed over long periods of time without tearing. The material is lightweight, tubes of up to 20 meters weighing only a few grams.
According to the present invention there is provided a recreational device comprising an elongate tube of thin, flexible, gas-impermeable and substantially non-elastic plastic material, the device being adapted to be at least partially inflated, to be operatively sealed at both ends and to be capable of being bent and tied into knot-type forms when partially inflated.
Thus the invention provides a new use of such tubes as an amusement device, children's game, advertising medium, flotation device for use in shallow water, sculpture medium or decorative medium. Preferably, the device of the invention is a tube with diameter from 15 to 200 cms., preferably 20 to 100 cms., and has a length of 1 to 5 m., preferably 2 to 3 m.
The device of the invention may be provided in kit form with a set of instructions. It can also be provided with a carrying case for ease of transport.
The present invention also provides simple methods of inflating the plastic tubes to employ the plastic tubes as recreational devices.
The tube of plastic material which constitutes the device of the invention is adapted to be at least partially inflated and operatively sealed at both ends and is capable of being bent and tied into knot-type forms when so partially inflated. In accordance with specific recreational uses of the device of the invention, the inflated tube may be used as a flotation device for supporting a person in shallow water, as an amusement device, an advertising device or as an art medium.
The invention also provides a recreational device including first and second elongate tubes of thin, flexible, gas-impermeable and substantially non-elastic plastic material, the tubes being adapted to be at least partially inflated and to be sealed at respective first and second ends and including a conduit to which second ends of the tubes are adapted to be sealed, the conduit in use allowing passage of air from said first tube to said second tube, said first and second tubes being adapted to be capable of being bent and tied into knot-type forms when partially inflated.
As already mentioned, the device may be in kit form with instructions for use. Such instructions may specify certain ways of inflating the tube which constitute further aspects of the present invention. Thus, the invention also provides a method of inflating such a tubular recreational device by operatively sealing one end of said tube; manually maintaining the other end of said tube open to the ambient atmosphere to allow air to flow into said tube from a given direction; moving said tube toward a given direction to facilitate the flow of air into said tube; and operatively sealing said other end of said tube when said tube is at least partially filled with air. The step of moving the tube toward the given direction may specifically be accomplished by simply running with the tube. With an alternative method inflation is performed by operatively sealing one end of said tube; manually maintaining the other end of said tube open to the ambient atmosphere; repeatedly moving said other open end of said tube up and down; orienting said other open end of said tube to facilitate the flow of air into said tube during at least a portion of the up and down motion; and operatively sealing said other end of said tube when said tube is at least partially filled with air. The step of orienting the end of the tube to facilitate the flow of air into the tube may include selectively changing the orientation of the end of the tube as a function of the up and down motion to facilitate the flow of air into the tube during both the up and down motions, thereby "scooping" air into the tube.
The invention will now be described in more detail by way of example with reference to the accompanying drawings in which:

With general reference to the Figures, industrially available thin, flexible, gas-impermeable and substantially non-elastic plastic material 2 is provided in the form of a long tube. According to the present invention, such material may be formed of any plastic having such properties including polyethylene, polyvinyl chloride or polypropylene. Typical uses of such plastic material include use in agricultural hot-houses, packing and plastic bags. However, upon the inflation thereof and the closing of the ends, a large balloon-type structure is produced which readily lends itself to use in children's games, as an art or advertising medium, decoration, or a flotation device upon which people can rest and float in shallow water.
With specific reference to Figure 1, the thin plastic material 2 is very lightweight and flexible such that when deflated, the material may be folded into a very compact form and placed in a small plastic carrying case 4 or any other convenient carrying means.
Two methods of inflating the plastic tube 2 in accordance with the present invention will be described with reference to Figures 2 through 5 and 10. As shown in Figure 2, one of the ends of the plastic tube 2 is operatively sealed by means of a knot 8 or by any other convenient means such as by twisting a paper-covered wire over the end of the tube in a well known manner, or by any other suitable means. As shown in Figure 3, the user manually maintains the other end of the tube 6 open to the ambient atmosphere to thereby facilitate the flow of air into the tube. While Figure 3 illustrates the use of both hands to maintain end 6 of the tube open to the ambient atmosphere, only a single hand may be required under many circumstances, especially when larger-diameter tubes are being used, as illustrated in Figure 4, for example. While maintaining end 6 of the tube open to the ambient atmosphere, the user, if outdoors, may simple run with the tube while holding open the unsealed end 6 so that the movement through the atmosphere is used to force air to enter the tube 2. Since the plastic material is very lightweight, the entire tube will thus be easily inflated, and the unsealed end 6 may then be sealed in a manner similar to that employed for the other end, thereby preventing escape of air from the gas-impermeable tube.
The second method of inflating the tube is illustrated in Figure 5. Again maintaining end 6 of the tube open to the ambient atmosphere, the user, if indoors or confined within a small area, rapidly moves the open end of the tube up and down, the opening of the tube facing the direction of upward or downward travel. Air will thus be forced into the tube, allowing the tube to be inflated without running.
Figure 10 illustrates a technique for further facilitating the flow of air into a plastic tube, especially for relatively long tubes. Upon the initial flow of air into the open end of the tube, the air inside the tube may be forced toward the tied end of the tube in the following manner. First, the user grasps the open end of the tube to prevent the escape of air from the tube, the user's hands being in positions "A" and "B" as shown. The air at the open end of the tube may be forced toward the sealed end of the tube by the user sliding his hand toward the sealed end of the tube while constricting the tube to keep as little air as possible from escaping at the open end. As the user moves his hand to position "C" to force the air toward the sealed end, the user's other hand is kept at the open end in position "A". Thus, by repeatedly scooping air into the open end of the tube as shown in Figs. 4 or 5, and by repeatedly forcing the air toward the sealed end of the tube, extremely long tubes may be tightly inflated. A knot may then be formed at position "C" to thereby seal the end of the tube.
Fig. 6 illustrates a cross-section view of the plastic tube taken along line 6-6 of Fig. 5. The plastic material is typically very thin such as polyethylene or polyvinyl chloride or polypropylene. The material is typically translucent and available in a wide range of pastel colours. Additionally, such plastic material is usually very durable and can be twisted and flexed over long periods of time without tearing. The material is also very lightweight, tubes of up to 20 m. weighing only a few grams.
While the inflated tubes may be used by children simply as a balloon-type amusement device, Figures 7-9, llA, 11B and 12 illustrate further uses of the inflated tube. Figure 7 illustrates a pair of tubes 2 and 2' being tied to one another at their ends by a common knot 8'. Additional inflated tubes may further be tied to the common knot 8' or may be tied to other parts of the tubes 2 or 2' or to the other end of tubes 2 or 2' to form large structures of arbitrary shapes and configurations.
Figure 8 illustrates a plurality of inflated tubes twisted together and tied in knot-type forms which may be used as a flotation device in a shallow body of water 10. In accordance with this specific embodiment of the invention, a plurality of tubes may be used as a "free-form" water raft. It should be noted, however, that the tubes should not be used as a safety device or flotation device in deep water, since the thin plastic material is subject to punctures.
The tubes are thus rendered safe as flotation devices only in shallow water where the user can otherwise comfortably stand with his upper body well above the water level.
Figure 9 illustrates the use of a plurality of inflated tubes as an art medium, specifically a sculpture medium. Tube 14 is shown as being partially inflated and disposed in an arc or "rainbow" configuration, while tube 16 is vertically oriented, a knot being formed at the top 18 thereof. By painting or printing messages or slogans on the surface of the tubes, the tubes may be used as an advertising medium as well as an art or sculpture medium.
If it is desired to bend and shape the tube at a plurality of locations, the tube should not be fully inflated since the plastic material is substantially non-elastic.
Figures 11A and llB illustrate a technique of interconnecting two or more plastic tubes using cylindrical conduits as an alternative to the technique described by reference to Figure 7. Specifically, Figure 11A illustrates the technique of providing a straight cylindrical conduit 20 disposed within one end of tube 2a and within one end of tube 2b. The end of tube 2a is sealed around conduit 20 by means of a string or wire 22a, while the end of tube 2b is similarly sealed about conduit 20 by means of a string or wire 22b. In Figure 11B, the cylindrical conduit 24 is "Y" shaped, thus interconnecting three tubes 2a, 2b and 2c. The ends of tubes 2a, 2b and 2c are sealed around conduit 24 by means of strings or wires 26a, 26b and 26c, respectively.
Conduits 20 and 24 may be made of lightweight plastic or other suitable material, and are hollow to thereby allow the flow of air from one tube to another, as shown in the figures. More than one tube at a time may be inflated in this manner, especially by utilizing the technique illustrated in Figure 10 for facilitating the flow of air into the far end of the furthest tube from the opening of the inflating tube.
Still another use of the tubes is as a lighter than-air body which will naturally rise in the ambient atmosphere, yet which requires no special gas such as helium or the like. Specifically, by inflating a large tube which is colored black or another dark color, the air within the tube, when expected to direct sunlight over a given period of time, will rise significantly in temperature since the black or dark material of the tube will react to the sunlight and produce heat thereby heating the air within the tube. As the air within the tube increases in temperature it expands, and the tube will eventually become bouyant in the atmosphere and will naturally rise, as illustrated in Figure 12.
Unlike other balloon-type amusement devices, the present invention is readily available in almost unlimited lengths. The balloon-type structures may be as large as 20 m. in length or more, yet fold up to a very compact size when not inflated. The plastic material is tough and durable and is fully reusable. However, should small holes or rips in the material occur, such can easily be repaired by simply using an adhesive, cellulose or plastic tape to cover any holes or rips. Finally, while the plastic tube may be inflated using conventional means such as an air compressor, the tube in accordance with the present invention readily lends itself to inflation by the above described methods which require no mechanical equipment and which may easily be accomplished by children.
While the preferred embodiments have been described in the specification, the scope of the invention shall be defined with reference to the following claims.
