Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT FLOTATION SYSTEM FROM TIRES The following statement is a full description of this invention, including the best method of performing it known to me.
1 FLOTATION SYSTEM FROM TIRES This invention deals with a structure able to float constructed primarily of tires.
Floating water borne structures (Rafts and Jetties) have many uses, particularly in areas of high tidal range or where the nature of the bottom is not suitable for construction or when it is desirable to move the structure from one place to another.
In a floating structure, wether jetty or raft, there are three key elements.
1. Flotation sufficient to carry the weight of the structure, plus the required load.
2. Structural strength sufficient to withstand the forces of wind and tide, as well as any applied forces such as being towed.
3. A deck or platform suitable for the intended purpose of the structure.
This invention deals with a method of construction which incorporates the flotation and the structural qtrenpth for flnAtinr rafts or ietties The structure is formed from a number of prepared suitable tires arranged in a regular pattern and secured with suitable bars or bolts.
A prepared suitable tire is one where the tire body, that is the section normally filled with air is filled with flotation material and the inside diameter the hole is greater than half of the outside diameter. Generally all tires in a particular structure would be the same physical size and filled in such a way as to be the same width.
S The tires are arranged upright (the same orientation as when they are fitted to a vehicle) in rows and columns as shown in the sketch with the tires in the odd numbered columns being placed halfa tire diameter ahead of the tires in the even numbered columns.
When this arrangement is viewed from the side (that is looking at the holes in the tires) part of the hole of the tires in even numbered columns is visible through the holes of both tires in the odd numbered columns.
By passing a suitable sized bar through each of these spaces, the tires are linked together to form a chain or mat, the length of which is determined by the number of tires in the columns, and the width of which is determined by the number of columns and the length of the bars.
The bars which pass through each tire in an even numbered column are considered a pair.
The ends of each pair of bars are prevented from spreading and the tires in the first and last column are prevented from coming off the bars by suitable joining plates which may have a hole at each end to suit the size of the bars, the distance between these holes being half the outside diameter of the tire.
The ends of the bars may be threaded and fitted with nuts, or some other suitable method may be used to retain the joining plates on the bars and also allow the effective length of the bars to be reduced, thereby applying a tensile force in the bars and a compressive force on the sides of the tires.
The bars could take the form of bolts or cables or any other material able to apply a compressive force to keep the tires together and able to resist the shear force of the tires moving apart lengthwise as would occur if the structure were pulled by the ends.
As any tire is not rigidly attached to any other tire, the completed structure has flexibility to allow it to accommodate the movement of the water it is floating on.
The strength of the structure in tension in the lengthwise direction is the shear strength of the bars or the force required to tear the tires.
The strength of the structure in the crosswise direction is the tensile strength of the bars.
The linking together of tires will be done initially with lightweight pipe or tube such as PVC which is easily handled. The linking bars will then be passed through the PVC pipes and the construction completed.
The PVC pipes can be either left in place or removed.
Claims (4)
1. A floating structure is made by linking together suitable sized and prepared tires with bars or bolts to form a chain or mat.
2. The tires of claim 1 are those where the inside diameter is greater than half the outside diameter.
3. The body of the tires of claim 1 are filled with flotation material.
4. The bars of claim 1 will link the tires together to form a chain of unlimited length and width limited only by the length of the bars.
