Abstract

The wheel comprises a diabolo shape body <B>D</B>, which has propulsion paddles <B>A</B> fitted around its hub <B>C</B> and an axle mounting hole <B>E</B> running through the centre. The two outer circumferences of the body <B>D</B> are fitted with rubber or similar material tyres <B>B</B> for stability and grip on hard surfaces. The diabolo shape body hub <B>C</B> is designed to have a larger diameter than the axle mounting hole <B>E</B> to allow sufficient ground clearance, and prevent the wheel from sinking to axle depth. This design enables continued smooth rotation of the wheel. The two side faces <B>F</B> of the body <B>D</B> can be flat and flush or alternatively dished. Two or more wheels can be connected together by various means to form a type of roller.

Description

Page 1
MULTI - TERRAIN WHEEL
This invention relates to a Diabolo shaped multi terrain wheel.
Existing wheels tend to be designed to operate on specific terrain. The disadvantage being that when a wheeled device is moved from one terrain to another ie: tarmac onto sand, it will sink and get stuck. Even where wheels are currently fitted with special tyres for better grip in soft terrain, the problem still exists that they have insufficient ground clearance below the axles to which they are fitted. As a consequence they create a build up of soft terrain up to axle level, which eventually stops rotation. Also many existing wheeled devices for carriage and transportation are currently unable to operate at all on soft sand or snow, and are strictly limited to use on firm terrain only, for these very reasons. These limitations effect many groups of people needing to access soft terrain areas ie: beaches, coastal paths, such as emergency service professionals, wardens & rangers, disabled & wheelchair users and other general public.
In order to overcome this problem, the invention proposes:- A wheel comprising a diabolo shaped body, fitted with propulsion paddles around its hub, and an axle mounting hole through the body centre.
Page 2 Advantages The multi - terrain wheel when fitted to various devices has the advantage of allowing easy transport and carriage over soft terrain ie: sand I snow, due to the fixed paddles, which remove any build up of sand etc. as the wheel revolves, thus aiding propulsion. In addition, because the hub of the diabolo shaped wheel body has been specifically designed to be larger than the diameter of the axle mounting hole, it prevents the wheel from sinking to axle depth.
Together, the propulsion paddles, the large hub, and the diabolo shaped body, combine to maintain axle ground clearance and continued smooth rotation of the wheel.
Preferably the two outer circumferences will be fitted with solid rubber or similar tyres to aid stability and grip on hard terrain.
Preferably both side faces of the diabolo shaped body will be flat.
Page 3 The invention will now be further described in more detail with reference to the accompanying drawings in which:- Fig 1. shows the multi terrain wheel in Perspective, viewed from the front.
Fig 2. shows the multi - terrain wheel in Plan View Fig 3. shows the multi - terrain wheel Side View Detailed DescriDtion With reference to these drawings the invention comprises: A diabolo shape hollow or solid moulded body D which has propulsion paddles A fitted around its hub C. and an axle mounting hole E running through the centre, as shown in Fig I The two outer circumferences of the body D are fitted with rubber or similar material tyres B for stability and grip on hard surfaces, best shown in Figs I & 2 The diabolo shape body hub C is designed to have a larger diameter than the axle mounting hole E as Fig I to allow sufficient ground clearance, and prevent the wheel from sinking to axle depth. This design enables continued smooth rotation of the wheel. The two side faces F of the body D are flat and flush, as shown in Fig 1. As an alternative the side faces F can be dished. Two or more wheels can also be connected together by various means, to form a type of roller. Mounting points may be fitted as a further alternative to axle hole E.
