How to Buy an Inflatable Boat

by: fulong   Keywords: electric, Inflatable, Boat

An electric inflatable boat is provided with a multi-keel by having an inflatable member or members constrained to lie between the flexible skin of the boat and a reaction surface. Preferably there is a rigid deck as a reaction surface overlying the flexible skin with two parallel inflatable tubes under the deck spaced apart by a distance equal to half the width of the deck. In a load carrying inflatable boat for carrying a plurality of passengers having a flexible underwater skin, a reaction surface overlying said skin and an inflatable former lying between the said skin and the said reaction surface and cooperating therewith to form a keel for the boat, the improvement consisting of having one or more inflatable formers adapted to cooperate with the said reaction surface and the said skin to form when inflated at least two spaced apart keels for the boat on respective sides of the centreline of the boat and providing between them a channel of the skin centred on the centreline of the boat and having a profile varying with the loading of the reaction surface to provide a self-compensating underwater surface for the boat which surface adapts itself to the planing characteristics required for different loads, the cross-section of the undersurfaces formed by said skin being substantially constant along the length of the keels when said members are inflated.

An inflatable boat is not only a lot of fun, but also handy, whether you're trolling around a lake or docked at a mooring and want to get to shore. Here's how to buy an electric inflatable boat .Check out your local boat store. West Marine is a nationwide chain, but there are probably others in your area as well. All boating stores sell inflatables. Also, stores like Target, Wal-Mart and K-Mart have moved into the inflatable boat market as well.

This invention relates to inflatable boats, that is boats having inflatable flotation members, and is concerned with the keel arrangements of such boats. There have been numerous prior proposals relating to the underwater surface of inflatable boats, and it has also been suggested that for rigid-hull boats multi-keel underwater surfaces should be provided. Thus in British Pat. No. 1,273,692 there is disclosed a boat hull provided in a forward section with a twin keel and in a rearward section with a single keel. The forward twin keels may each be lowerable or raisable to improve riding characteristics of the hull.

In British Pat. No. 1,319,072 there is disclosed a power paddler boat in which the shape of the hull is a function of the hull construction itself of a number of inflatable tubes which cooperate to provide a generally U-shaped or V-shaped cross-section for the hull.

In British Pat. No. 1,362,677 there is disclosed an inflatable boat having inflatable side walls serving as floatation members, a flexible underwater skin, a rigid deck and between said skin and deck an inflatable former member along the longitudinal centre-line of the boat shaping the flexible skin to form a central keel.

However in none of these prior art proposals has it been appreciated or suggested that by having a boat with a flexible underwater skin and inflatable former members to cause the undersea surface of the boat to have a multi-keel construction, automatic adaptation of the planing characteristics of the boat to the load carried in the boat could be achieved. Peruse tag sales for an inflatable boat. This seems like an effort, but with the web it has become much easier. Check out craigslist or other community sites for information on upcoming tag sales. There people will list the valuable items they have for sale. If someone is selling an electric inflatable boat , contact them and arrange to check it out.

The present invention is concerned to form, by inflation, a multi-keel underwater surface. The proposal uses the flexiblity of a fabric skin, stretched over shaped inflated formers, to allow inherently the adaptation of the shape of the underwater surface to load conditions being experienced. This gives a self-compensating underwater surface which retains its good planing performance under all load conditions. The use of parallel twin inflated formers (preferably separate sacs or tubes) to give a generally W-section underwater surface is simplest and at the same time yields very good results. The spacing apart of the parallel formers may be 50% of the deck width of the boat.

The floor will provide the reaction surface against which the formers act and will most conveniently be rigid panels extending the whole width of the boat and terminating under, and being supported by, the inflated buoyancy tubes of the boat.

Boats thus constructed may be of any appropriate size but especially suitable will be application of this invention to boats of larger sizes, e.g. 7 meters length upwards, whether with single or multiple engine installations. On these sites you'll be able to get great deals with deep discounts either by bidding, as on ebay, or purchasing from a direct manufacturer such as Ambition Inflatables.Take a spin by your local marina. Not only do they have slips for you to buy, but they sell boats, too. And since most people who have a larger water craft need a kid power paddler boat chances are they will carry them as well. You might also get a great deal, as they are looking to make their money on the big-ticket gigantic boats and care less about the small profit margin for an inflatable boat.

The Hippo water roller

by: fulong   Keywords: water, roller

The Hippo water roller , or Hippo roller, is a device for carrying water more easily and efficiently than traditional methods, particularly in the developing world. It consists of a barrel-shaped container which holds the water and can roll along the ground, and a handle attached to the axis of the barrel. Currently deployed in rural Africa, its simple and purpose-built nature makes it an example of appropriate technology.The drum of the Hippo water roller is made from UV stabilized linear low-density polyethylene and is designed to cope with the rough surfaces found in rural areas. The drum's volume is 90 liters (about 24 gallons) [1]. It has a large opening (135 mm / 5.3 inch diameter) for easy filling and cleaning[citation needed]. The size of the opening was originally determined by the availability of a large enough lid. The lid then on its part determined the roll radius of the roller, since enough clearance was required with the lid fitted to keep the latter clear from the ground and any obstacles which might damage it. The lid was eventually further recessed on later models to enhance its protection.

The steel handle allows the roller to be pushed or pulled over difficult and very rough terrain. The overall width of the roller with handle attached was determined by measuring the average width of a standard doorway and sized to allow it to be pulled through freely[citation needed]. This parameter together with the roll radius and the rounded shoulders eventually determined the average volume of 90 liters. The steel handle is fitted with special polymer end-caps to reduce friction and wear and prolong the life of the pivot cavities in the drum.






During development a water roller manufacturer was drawn behind a vehicle over a dirt road at 20 km/h for 15 km without any significant signs of wear on both the roller outer surface or pivot cavities.The roller is rounded at the shoulders to simplify tilting when wanting to pour from the full roller. However, the roller is also very stable in the upright position when it rests on a small, flat surface. The roller has hand grips at the bottom and top to make emptying the container easier.The barrel, originally called "Aqua Roller", was the brainchild of two engineers, Pettie Petzer and Johan Jonker  Petzer and Jonker were recognized for their work on the Hippo Roller in 1997 with the "Design for Development Award" by the South African Bureau of Standards and its Design Institute.

It is claimed that approximately five times the amount of water can be transported in less time with far less effort than the traditional method of carrying 20 liters (approximately 5 gallons) on the head.
Claimed benefits include:
    * time savings (fetching water can be very time consuming in some poor rural environments);
    * reduced effort;
    * reduced strain (carrying heavy weights on the head every day for years puts strain on the body, particularly the vertebral column);
    * increased water availability, with benefits for health and perhaps even enabling vegetables to be grown;
    * hygienic storage due to the sealed lid on the roller.

Although the Hippo roller was mainly designed as a water gathering aid for underprivileged communities, several other uses have since been discovered. Because of the Hippo water rollers tightness it can act as a watertight container to keep valuables and clothes dry when going downstream in white water rapids on extreme excursions.
It can also suffice as a container to be dropped with life saving contents from helicopters or low flying fixed-wing aircraft in flooded disaster areas. This might include food and medical supplies, warm dry clothing and blankets, and naturally, water. The polyethylene is lighter than water and will stay only partly submerged, even with fresh water in it. In fact, some rollers have been distributed pre-filled with grain or other foodstuff to villages.One of the draw-backs of the distribution of the rollers is that the rollers cannot be stacked efficiently to save space; thus transport capacity is wasted.

Infotech, an information technology company, initially sponsored the project as a social responsibility project known as the Hippo Water Rollers Trust Fund.  Currently, the project is supported financially by donor funding which comes from individuals, corporate businesses and non-profit organization partners.  is a non-governmental organization in the United States created to raise funds there.27,000 Hippo rollers have been distributed so far. As part of the investigation into the alleviation of poverty and scarcity of water in the far northern parts of Namibia, the Social Sciences Division of the Multi-Disciplinary Research Centre at the University of Namibia, sponsored by UNICEF's Directorate of Rural Development bought 1000 rollers and distributed them into the community. Six months after the introduction they launched an evaluation on the success and performance of the rollers as well as the social impact of the roller on the lives of the recipients.

Typical examples of inflatable water toys

by: fulong   Keywords: inflatable, water, toys

Typical examples of an inflatable include the electric inflatable boat , the balloon, the airship, furniture, kites, and numerous air-filled swimming pool toys. Air beams as as structural elements are finding increasing applications. Balloons are inflatables.

Smaller-scale inflatables (such as pool toys) generally consist of one or more "air chambers", which are hollow enclosures bound by a soft and flexible airtight material (such as vinyl), which a gas can enter into or leave from through valves (usually one on each air chamber). The design dependence upon an enclosed pocket of gas leads to a need for a very durable surface material and/or ease of repair of tears and holes on the material, since a puncture or tear will result in the escape of the gas inside (a leak) and the deflation of the inflatable, which depends on the gas's pressure to hold its form. Detectable leaks can be caused by holes (from punctures or tears) on the material, the separating of seams, the separating of valve parts, or an improperly shut or improperly closing valve. Even if an inflatable possesses no macroscopic leaks, the gas inside will usually diffuse out of the inflatable, albeit at a much slower rate, until equilibrium is reached with the pressure outside the inflatable.

Many inflatable water toys are made of material that does not stretch upon inflation; a notable exception of this is the balloon, whose rubber stretches greatly when inflated.
The airship is usually inflated with helium as it is lighter than air and does not burn unlike hydrogen airships such as the Hindenburg.
Inflatables are also used for the construction of specific sports pitches, military quick-assembly tents, camping tent air beams, and noise makers. Inflatable aircraft including the Goodyear Inflatoplane have been used. Inflation by dynamic ram-air is providing wings for hang gliding and paragliding.

Inflatables came very much into the public eye as architectural and domestic object when synthetic materials became commonplace. Iconic structures like the US Pavilion at the 1970 Osaka Expo by Davis and Brody [3] and Victor Lundy's travelling pavilion for the Atomic Energy Commission popularized the idea that inflatables can be a way to build large structures with very extendend interior spans without pillars. These great hopes for inflatable bouncer structures would later be dashed by the many practical difficulties faced by inflatable buildings, such as climatization, safety, sensitivity to wind and fire proofing that, currently, restrict their use to very specific circumstances.

The DVD Ant Farm has directions for making your own inflatables, using plastic bags and an iron. The low technological barrier to building inflatables is further lowered by DIY instruction sets like the Inflatocookbook.
A patent was granted in Australia in 2001 for a "Manually portable and inflatable automobile" (Australian Patent Number 2001100029), however no known practical form of this type of inflatable has yet been commercialised.
Large scale low-pressure inflatables are often seen at festivals as decorations or inflatable games. These are made out of rip stop nylon and have a constant flow of air from a blower inflating them.
In some cases, an inflatable roof is added to an otherwise traditional structure: the biggest example in the world is currently the BC Place Stadium in Vancouver, British Columbia. Another example can be found in the Roman amphitheater of Nîmes.
Many companies use inflatables in the shape of their product or service, they do this because you need no permission to display them from your local council or authority and they are very easily moved from place to place.

During the 2000s, inflatable water toys have replaced the plastic blow-molded yard decorations used as Christmas décor at many U.S. homes, and are also now used as Halloween décor and for other occasions as well.

These are made of a synthetic fabric, of which different colors have been sewn together in various patterns. An electric blower constantly forces air into the figure, replacing air lost through its fabric and seams. They are internally lit by small C7 incandescent light bulbs (also used in nightlights), which are covered by translucent plastic snap-on globes that protect the fabric from the heat if they should rest against it.

Inflatables come in various sizes, commonly four feet or 1.2 meters tall (operated with a low-voltage DC power supply and a computer fan), and six or eight feet (1.8 to 2.4 meters) tall, running directly from AC mains electricity. Like inflatable water slide , outdoor types are staked to the ground with guy wires (usually synthetic rope or flat straps) to keep them upright in the wind, though being rather flimsy this does not always work. Heavy snow or rainwater which has accumulated may also prevent proper inflation.

While these store compactly, there are disadvantages, including the large amount of electricity needed to constantly keep them inflated. While they can be turned off in the daytime, this leaves the figure deflated, and subject to the rain and snow problem. Freezing rain, heavy snow, or high winds may also cause inflatables to collapse. Additionally, like a tent, they must be completely dry before being packed for storage, or mildew may be a problem (especially if kept in a basement).

Decorative inflatables are made in many popular characters, including Santa Claus and snowmen for Christmas, and ghosts and jack-o-lanterns for Halloween. Several trademarked characters are also produced, including SpongeBob SquarePants, Winnie the Pooh, and Snoopy and Woodstock from Peanuts. There are also walk-though arches and "haunted houses" for children, and items for other holidays like Uncle Sam for Independence Day, and palm trees for backyard summer cookouts.

Take your kids to play with paddler boats

by: fulong   Keywords: paddler, boats

The invention relates to a breakdown double-bladed kayak paddle which may be taken apart for storage. The paddle may be assembled for paddling a kayak or like boat and the blades may be set in a number of operational positions to provide the orientation of the blades relative to each other as desired by the boater.
Adjustable and breakdown power paddler boat have been heretofore known. In British Pat. No. 1,312,320 an oar is disclosed which can be taken apart. The sections of the oar are scarfed so that they fit together and form a tight joint. A threaded nut is tightened down over a threaded section on the other part to make a tight joint.

Spring rain brings puddles... And where you find puddles, you'll find kids!
Have fun in the puddles that spring brings by making a puddle paddle boat!
This activity is a fun way to experiment with Newton's Third Law of Motion - action and reaction!
For every action, there is an equal and opposite reaction.

The disclosure relates strictly to the joint of an oar and not to the double bladed paddle having multiple operational positions wherein the blades are oriented at different angles with respect to each other, nor to the elimination of torque stresses on a joint connection for fitting blade sections together in multiple positions.

U.S. Pat. No. 3,970,032 discloses power paddler boats whose blade can be set at different angles for varying the pitch. A quick release coupling is provided which is somewhat different in construction than that proposed in the instant invention.
From a piece of cardboard, measure and cut out a 4″ square. If you prefer, use our Paddle Boat template and diagrams to cut out the shape (see the link at the bottom of this article).Shape the paddle boat by cutting a point at one end and a 2″ square cut-out from the other end, as shown on our template.

Accordingly, an important object of the present invention is to provide a double-bladed boat paddle having a number of operational blade positions which can be broken down into two parts for transportation and storage, yet has a construction which is of sufficient integrity to withstand the rigors encountered in whitewater and other rough water paddling conditions.

Still another object of the present invention is to provide a breakdown boat paddle having a joint connection for providing a plurality of operational blade positions in which torque stresses are effectively relieved from the paddle lock of the joint connection.

Still another important object of the present invention is to provide an interlocking joint connection for a double-bladed breakdown power paddler boat manufacturer   which has high integrity and reduces the torque stresses encountered in the jiont section to provide a highly versatile paddle which can be used in a number of paddle blade configurations.
Wrap a rubber band around the end of the paddle boat, and tape it to the paddle.Twist the paddle toward you to wind the rubber band, then place the paddle boat in the water and watch it go!

For a longer lasting boat, use balsa wood instead of cardboard.Experiment by twisting the paddle away from you - which way does your paddle boat travel?Try building a larger paddle boat. Did it work as well or better than the 4″ model?Decorate your paddle boat using crayons or permenant markers. Come up with some wild designs!Have puddle paddle boat races with a friend! See who's boat can travel the farthest; who's is the fastest; the slowest; the one that travels in a straight line; etc.The Science: Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. When the paddle pushes against the water, the boat moves forward - in the opposite direction of the paddle.

The above objectives are accomplished according to the present invention by providing a double-bladed power paddler boat having first and second sections which may be taken apart. Each section includes a paddle blade at one end and a jointed end at the remote end thereof. A tubular sleeve is carried by a first section which is received in a hollow portion of a second section so that a double layered construction is provided in the joint area. A depressable latch button is carried within the sleeve for interlocking in the first and second sections when joined together. A number of circumferentially spaced latch openings are formed in the second section through which the latch button protrudes to provide a latch assembly which locks the first and second sections together in a number of rotatable positions wherein the paddle blades are set at a desired angle relative to each other. Each of the jointed ends of the first and second section includes a number of circumferentially spaced angular projections which extend outwardly from the end of each section and intermesh with one another to positively lock the sections together against rotation. The angular projections correspond in their angular spacing to the circumferential spacing of the latch openings. The first and second sections may be separated from each other on the interfitted sleeve and rotated relative to each other and locked in a desired operational position with the angular projections engaged with each other. The interlocking angular projections of the jointed ends prevent any torque stress from being produced on the latch assembly as encountered during paddling.
