Definitions
- the invention relates to axles used for swimming pool cleaners which have wheels.
- Pool cleaners of this kind invariably have axles which are made of stainless steel. At least one pair of wheels is driven to advance the cleaner along a submerged surface.
- the drive mechanism usually includes a turbine. This is driven by flow of water through the cleaner to or from a pump for the pool filtration system.
- the cleaner is connected to the pump by a flexible hose in the usual manner.
- the turbine is connected to the wheel axles through a combination of shafts and gears.
- axles are usually machined to the required dimension. Gears and/or wheels are then secured to the axles as necessary.
- the steel axles can be bent. This is particularly so if someone stands or accidentally jumps on a cleaner while it is in use.
- a swimming pool cleaner wheel axle that is moulded to form from plastics material.
- the invention further provides for the axle to be hollow; and for the axle to be injection moulded.
- axle to have mounting formations for gears and/or wheels; for the mounting formations to be longitudinal splines; and for the ends of the axles to have wheel retaining formations.
- axle to be reinforced by at least one metal rod provided therein; and for the axle to be moulded around the rod.
- Figure 1 shows a perspective view of part of a swimming pool cleaner; and Figure 2 shows a perspective cross-sectional view of a rear axle of the pool cleaner.
- a swimming pool cleaner (1 ) having four turbine driven wheels (2) is shown.
- Front (3) and rear (4) axles connect the pairs of wheels (2) respectively.
- the axles (3) and (4) are injection moulded from suitable thermosetting plastics material.
- the axles (3) and (4) are made hollow, with a longitudinal bore resulting from the moulding process which is used. This involves moulding each axle (3) and (4) around a core that is removed once the plastics material has set to a suitable degree.
- the bore is not shown in the drawings but will be appreciated by a suitably skilled person. It may extend the full length or part of the length of the axle (3) and (4).
- axles to be made with a wall thickness within the recommended specifications for a particular moulding plastics material.
- the optimum thickness is based on the setting characteristics of the material.
- the slower cooling of material in the centre of a solid axle would compromise overall strength and resilience compared to a hollow moulded counterpart, made in accordance with this invention.
- axles (3) and (4) may be made is the acetyl plastics material used in injection moulding. It has however been found that this material denatures to some degree in heated swimming pools. Other suitable materials with resistance to warmer water or for use in other conditions will be within the competence of a suitably skilled person. The material used will also preferably have some self-lubricating quality by virtue of a suitable additive.
- the front axle (3) in Figure 1 is shown fitted with only one wheel.
- the wheels (2) have a hollow spigot (5) through which the ends of the axles (3) and (4) extend.
- Four grooves (not shown) in the spigot (5) correspond to outer splines (6) on the axle (3).
- Each formation is provided as a head (7) which is formed by a circumferential groove
- the wheel spigots (5) are split longitudinally at
- a smooth journal (11 ) is provided spaced inwardly to each of the outer splines (6) of the axle (3) and (4) - see Figure 2.
- Each journal portion (1 1 ) is received in a split sleeve bearing (12) which is secured to the pool cleaner body.
- a side shaft (13) connects gears (14) on the front (3) and rear (4) axles. These gears (14) are similarly fitted onto the axles (3) and (4) respectively. This will be described for the rear axle (4) and with reference to Figure 2 where the parts can be seen more clearly.
- This is conveniently provided as an annular flange (15).
- In the area (16) between the journal (1 1 ) and flange (15) are four longitudinal inner splines. The inner and outer (6) splines are aligned with each other.
- An axial passage (17) through the gear (14) has corresponding grooves (not shown).
- the gear (14) is fitted onto the axle (4) and locates against the flange (15). Once fitted, the bearing (12) holds the gear (14) in place.
- the gear bearings (18) and gear (19) are fitted to the rear axle (4) adjacent the other end in the same manner.
- axles (3) and (4) described above are preferably, flexibly resilient to a degree sufficient to accommodate a load that would bend a pair of steel axles.
- the bore may be fitted with a metal rod.
- a pair of rods can be spaced apart to retain desirable resilience while adding support.
- Such rods will preferably be made of stainless steel.
- the accurately repeatable outer configuration of the axles (3) and (4) is maintained. It will also be understood that this can be achieved by having a moulded flexible sleeve which is fitted onto a rod for rigidity. Variations will be within the design competence of a suitably skilled person. These will include the variations necessary to adapt the axle for use with wheels of different pool cleaners.
- axle may have portions with a square cross-section. Additional changes to the described features which remain within the scope of the current invention will also be appreciated by a person skilled in the art

Abstract
La présente invention concerne un axe de roue pour nettoyeur de piscine qui est moulé par injection à partir d'une matière plastique. L'axe présente des formations de fixation pour engrenages et/ou roues. Ces formations sont des cannelures de préférence longitudinales, situées de manière appropriée le long de la longueur de l'axe. Les extrémités des axes présentent également des formations de retenue des roues. Dans un mode de réalisation, l'axe est creux et il peut être renforcé par au moins une tige métallique prévue à l'intérieur.
