The curvature of the diabolo can be varied to suit the size or height of a user. - The
shaft 26 can be moved todifferent slots 25 to vary the distance of the rotatable member above the water and forwards of thesurface 13 according to the size or height of a user and further adjustment can be obtained by varying theapertures arm 21. - In use, a person stands or kneels on the
surface 12 and leans forward until his torso, preferably the stomach or chest, engages on therotatable member 27 which thus in part supports him. The user then moves himself forward, possibly by pushing on thesurface 12 or by pulling or pushing onsupport 14 and moves gently forwards asmember 27 rotates to carry the user head first into the water. In some cases a helper may lift the user's legs, as shown, and assist in moving him into the water. The user may himself control the speed at which he moves forward, and the height of themember 27 can be adjusted as the user gains confidence. - In Fig. 3 a plurality of
rotatable members 27 are provided, spaced fore-and-aft, and may support a greater length of a user's body. Again the positions of themembers 27 can be independently adjusted up and down and fore-and-aft and as shown one or more of themembers 27 may be abovesurface 12. - In Fig. 4 the
rotatable member 27 is positioned below the level ofsurface 12 and again can be adjusted up and down onmembers 30 which can be adjusted fore and aft on members 31 e.g. bybolts 32 engageable in apertures 30a, 31a. - The arrangements may be detachably secured to the pool-side surround so as to be portable. There may be two or more such aids along the pool edge.
- Fig. 5 shows an arrangement of a number of rotatable members which are spaced and successively of lesser height.
- In one arrangement the rotatable member is partly submerged in the water but is of a size that its upper surface is above
level 12. - In the arrangement of Fig. 6, larger and smaller
cylindrical rollers axes frame 57 respectively are linked by an endless belt 54 extending round them. Theupper stretch 55 of the belt may have additional support betweenmembers roller 56 rotatable also inframe 57 which is disposed at both ends of the rollers. The method of use is as above with the user leaning on to the belt and moving forwards. As above, the rollers can in some cases be adjusted up and down and/or fore and aft. - The belt may for example be of rubber and may be stretched on the rollers or be a loose fit and may be soft or more rigid with padding for comfort.
- The belt 54 provides a rotatable member in that each part of the belt traverses a repeated path.
- In the various arrangements the rotatable members can move under the weight and thrust of user but alternatively or additionally, they may be moved (rotated) using a
handle 60 accessible from the poolside or be power driven for example byelectric motor 61. The sides of the aid or rotatable members may be encased for safety. - In the embodiment of Fig. 7 there are two
side frames 60 secured to thesurround 12 androller 51 is rotatably carried betweenarms 61 pivoted at 62 to theframes 60 and extending forwards.Releasable clamps 63 hold thearms 61 in selected positions of angular adjustment. Theroller axle 52 can be located in a selected aperture or slot 52a and theroller axle 53 can be located in a selected slot oraperture 53a to provide for fore-and-aft and height adjustment. - The length of
endless belt 55 is adjusted as required. Pivoting ofarms 61 enables the aid to be arranged for different angles of entry of the user into the water. - In the embodiment of Fig. 8
