WO 2004/073395 PCT/AU2004/000164 IMPROVED ANIMAL EXERCISER BY USING A RACEWAY IN A SWIMMING POOL FIELD OF THE INVENTION 5 This invention relates to an animal exerciser for exercising animals, typically but not limited to horses, in a body of liquid, typically water. BACKGROUND OF THE INVENTION 10 As with humans, animals also need to be exercised, especially racing animals, such as thoroughbred racehorses. The training of racehorses, for example, involves track work and walking of the horses. Due however, to the popularity of horse racing there is an ever-increasing demand on the availability of race tracks as a training venue. In order to maximise the use of and the 15 limited time available for track work, the horse or horses need to be well exercised or warmed up before actually running on the track. Typically the exercising of horses is achieved by simply walking the horses. There have been a number of ways in which horses can be exercised by walking. The simplest way is by tethering a horse to one end of a rope, the other end of which is held by 20 the trainer who encourages the horse to walk in circles. Another of the most common ways of walking horses involves a circular track with profiled rail runs and rotatable radial screens mounted in the runs between which screens the horses are positioned and driven around the track.

Received 13 July 2004 2 In recent times trainers have been attempting to train and exercise horses in water. One of the benefits arising from exercising horses in water is that the horses have to work against the resistance of the water to motion. As the public use of beaches and rivers increases, this is no longer practical or possible in many cases. The need for an 5 economical and cost efficient method is all too evident. The exercising of horses in water up to shoulder depth, working against the resistance of the water, ensures greater levels of fitness, whilst protecting the horses legs from excessive weight and stress levels. One of the current methods involves a narrow channel, usually circular, filled with 10 water through which horses are encouraged to either walk or swim. Such a prior art apparatus do not seem however to adequately exercise the horses correctly. This type of method and apparatus has the following disadvantages: 0 narrow channels; * inadequate water resistance for proper exercising of muscles because of the 5 design of the existing water-walkers, the water begins to flow in a 'whirlpool' effect, which actually carries the horses forward, thus greatly reducing the 'resistance' effect needed to exercise horses properly; and - excess water splashing when changing direction of horses in water-walkers. When changing direction in the existing water-walkers, the horses are faced with 0 a huge wall of water, caused from the 'whirlpool' effect of travelling in the previous opposite direction. This causes horses to start 'jumping' and not walking through the water, and which is unsafe especially for horses in rehabilitation or recovering from injury.

Figure 2 is an overhead view of the animal exerciser shown in Figure 1. 10 Figure 3 is plan view of a preferred non-circular animal exerciser according to Example 2. Figure 4 shows a cross sectional view of a preferred animal exerciser. 15 Figure 5 shows a cross sectional view of an animal exerciser with a flat floor. Figure 6 shows detail of a preferred grid panel. 20 Figure 7 shows detail of an alternate grid panel assembly.

WO 2004/073395 PCT/AU2004/000164 10 DETAILED DESCRIPTION OF THE DRAWINGS Example 1 5 Referring to Figures 1 and 2, the animal exerciser 1, according to Example 1, is generally illustrated by having a liquid holding means 10, typically a water reservoir, and a raceway means. The liquid holding means 10 is typically set inground and consists of a floor 11 and sidewall 12, typically made from a hard 10 setting compound such as concrete. As shown in Figure 1 the floor 11 of the liquid holding means has a level outer region 1la and an inner downwardly sloping region 11 b. The level outer region 11 a of the floor is adapted to allow the animals 2 to 7 walk upon. 15 The raceway means includes inner and outer fences 28, 29, rotatable vertical shaft 43, supported on a support assembly 41, a drive means 42, typically in electric motor or any other suitable drive means, radial arms 21 to 26, and grid panels 31 to 36. The inner and outer fences 28, 29 define a circular pathway 30 in which animals are encouraged to walk or swim through. The inner 20 fence 29 and the outer fence 28 have lower portions 28b, 29b under the liquid level 13 and have upper portions 28a, 29a extending above the liquid level 13. The outer fence 28 is spaced a sufficient distance from the sidewall 12 of the liquid holding means 10 to allow any current, turbulence and/or whirlpool effect WO 2004/073395 PCT/AU2004/000164 11 caused by moving animals to be absorbed and/or dampened by the body of water between the outer fence 28 and the side wall 12. The grid panels 31 to 36 attached to the radial arms 21 to 26 are adapted to extend downward into the pathway 30 so that as the radial arms 21 to 26 are caused to rotate via the 5 rotatable vertical shaft 43 and the drive means 42, the grid panels 31 to 36 come into contact with an animal in the pathway 30 so as to encourage the animal to move within the pathway 30. Animals enter and exit the pathway via a ramp 15 which typically having a gate to keep the animals in the pathway 30 during exercising. 10 To enhance the absorbing and dampening effect to the liquid caused by the animals movement through the pathway 30, baffles 51 to 57, 61 to 66 are positioned within the liquid holding means 10. Baffles 51 to 57 are attached to the side wall 12 of the liquid holding means 10 at spaced apart intervals such that 15 the current, turbulence and whirlpool effect are directed towards and absorbed/dampened by the baffles 51 to 57. The other baffles 61 to 66 are positioned in the body of liquid between inner fence 29 and the support assembly 41 to absorb or dampen any current 20 turbulence or whirlpool flow effect that may occur in that part of the body of liquid. The baffles 51 to 57, 61 to 66 can be adjusted, preferably, by way of cables and/or servo motors so that the baffles can be adjusted in accordance to WO 2004/073395 PCT/AU2004/000164 12 the amount and direction of current, turbulence or whirlpool effect caused by the moving animals. Example 2 5 Referring to Figure 3, there is shown a preferred non-circular animal exerciser 70 according to Example 2. Entry and exit into the raceway is via an entry/exit ramps 72 incorporating a fast washing area, 74. The exerciser is of an oblong shape with baffles 76, 78, 80, 82, 84, 86 positioned either end of the 10 exerciser to absorb the currents and turbulence built up as the animals exercise in a preferred direction. The baffles preferably have perforations or apertures to allow some water to flow through them. In this example, the grid panels 90, 92, 94, 96 mounted on 15 roller members 98, 100, 102, 104 in the form of wheeled bogeys mounted to run on track members 160. The roller members are spaced apart and connected by an endless chain 108 which is driven by a sprocket connected to a motor worm drive gear assembly 110. Currents produced by horses exercising or walking in one direction can be counteracted by water jets introduced into the pathway 20 against the currents thus produced by water jet means such as in the form of high-pressure pumps. The orientation of the baffles can also be changed according to the direction of the dampening needed. The centre region 112 of the exerciser can also be raised or dome shaped in cross section to enable sand WO 2004/073395 PCT/AU2004/000164 13 added to the water to return to the pathway. The sane is used to clean the floor of the pathway and to prevent any build up of fungal or algal organisms detrimental to the feet of the animals. 5 Figure 4 shows a cross section of a preferred animal exerciser 111 with a domed or raised centre portion 112. The raised centre provides sloped regions 112a, 112b to facilitate sand 114 added to the water 115 which has been displaced by the swirling motion 116 of the water and currents to return to the pathway. 10 Figure 5 shows a cross section of the animal exerciser with a flat bottom floor 120 wherein the grid panels 122, 124 are supported on arms 126, 128 connected by an endless chain which when driven by a motorised gear assembly pulls the bogies along the track thereby moving the grid panels to keep the 15 horses moving and exercising along the pathway. Figure 6 shows detail of a grid panel 112 and track and roller member assembly 127. The grid panel comprises a weld mesh screen 122a from which can be suspended a rubber drop sheet 122b with perforations 123a, 123b or air 20 holes to lessen wind resistance. The weld mesh is supported by an upper arm 126 which is connected to the wheeled bogies 130, 131a at either end. The bogies are adapted to run on the track members 134 atop the inner 29 and outer fences 28 defining the pathway. It will be obvious that the inner fence track WO 2004/073395 PCT/AU2004/000164 14 supports the driven bogey 130 and the outer fence track member supports an idler bogey 130a. Preferably for safety purposes, the arm 126 can be raised in the direction 5 of arrow 126a so that the grid panel 122 can be raised clear of the pathway. Figure 7 shows detail of an alternate grid panel assembly 140 which can be supported at one end only by a specially adapted roller means 142. In this version, the upper wheeled bogey 142d supports the arm 144 from which the grid 10 panel is suspended. The lower bogey 142b is connected to a vertical strut 145 and runs along the inner fence 146 thereby keeping the arm supported in the horizontal position as the grid panels are moved along the pathway. Also shown is the hinge support 148 for the arm, which can be raised 149 clear of the pathway for safety if necessary. The pathway is preferably lined with a rubber 15 mat 150 to cushion the hooves of the horses being exercised.
