Definitions
- the invention relates to a self-propelled rolling device for cleaning a surface immersed in a liquid, in particular a swimming pool liquid.
- Certain swimming pool cleaning devices are of the rolling type, that is to say comprising rotary rolling members (rollers, wheels, rollers, tracks, etc.) around transverse axes of rotation at least substantially parallel to the plane of bearing of the device defined by these running members, corresponding to the surface on which the device moves.
- Such devices can be self-propelled, that is to say incorporate and carry at least one motor (electric, hydraulic, etc.) driving at least one motor shaft whose rotary movement must be transmitted to at least one rolling member for drive it in rotation.
- the self-propelled apparatus comprises at least one electric motor powered by a waterproof electric cable plunging into the pool, and the output shaft (rotor) of which forms a motor shaft .
- a motorized electrical device is also generally equipped (cf. for example FR-2,584,442) with a waste suction electric pump and a filter bag for recovering waste.
- the device is, more often than not, more or less automatic and is generally called a robot.
- Such known self-propelled rolling devices with electric motors are relatively heavy, complex, bulky, expensive, have relatively poor hydraulic performance (suction of waste) in view of their cost, their weight and their bulk, and offer only a small amount of possibilities of aesthetic variations.
- FR-2,584,442 They are generally (FR-2,584,442) made up of an external rigid shell forming the main frame of the device carrying all of its constituent elements, namely on the one hand the rolling members and, on the other hand hand, the electric drive motor.
- the hydraulic circuit is generally vertical _, _ -, mecanic-_. , T / FR01 / 03933 going up between a lower entry in the hull and an upper exit of the hull.
- the latter is generally formed by two half-shells assembled to one another by a longitudinal or horizontal vertical joint plane.
- the transmission between the electric motor and the rollers is done by means of lateral transmission belts generally fixed on the side of the hull.
- the shell which simultaneously forms the hydraulic circuit and acts as a frame supporting the mechanical members, freezes the external shapes and the aesthetics of the device and must be of robust, heavy and expensive construction. Maintenance of the mechanical part is also difficult, long and complex.
- the invention therefore aims to overcome these drawbacks by proposing a self-propelled submersible surface cleaner which has a unidirectional hydraulic circuit (without sudden change in flow direction), simple, effective, but whose mechanical part is simple, light, robust, does not require a rigid shell and can be common to many different aesthetic models.
- the invention also aims to provide such an apparatus, the manufacture and maintenance of which are simple, rapid and inexpensive and in particular the assembly and disassembly of which are quick and easy.
- the invention relates to a self-propelled rolling device for cleaning a submerged surface, comprising in combination:
- a rigid transverse motor housing containing at least one electric motor and having at least one drive shaft, called the drive shaft, of at least one rolling member and at least one drive shaft, called the pumping shaft, a pumping member, these drive shafts opening onto the outside of the casing,

- the front bearing member (s) may be identical to the rear bearing member (s). They can be simple rollers guided between the flanges by their ends
- At least one of the flanges is formed by a cassette with an outer casing containing means for transmitting the motor movement - in particular a gear train.
- the two flanges carry transmission means.
- the apparatus comprises two independent separate drive motors (a left motor and a right engine), each of these.
- motors having a motor shaft (the apparatus comprising a left motor shaft and a right motor shaft), and two pairs of independent running gear, namely a pair of front running gear and a pair of rear running gear , the two rolling members (left and right) of the same pair (front or rear) were arranged in coaxial extension from one another and independent from each other in rotation, one of them being coupled via transmission means, to one of the two drive shafts, while the other is coupled, via transmission means, to the other drive shaft.
- the apparatus thus comprises a left front rolling member and a left rear rolling member coupled to the left motor shaft of the left drive motor; and a right front bearing and a right rear bearing coupled to the other right motor of the right drive motor.
- the two rolling members of the same pair extend between the flanges, one being guided by one of the flanges, the other being guided by the other flange, and are advantageously associated and axially guided one compared to each other.
- they are guided relative to each other by an assembly of the cylindrical telescopic type allowing relative rotations.
- This assembly and / or one and / or the other of the two rolling members can also be guided in rotation relative to the opposite transverse wall by an instant dismantling assembly - in particular with hooks - facilitating disassembly and reassembly.
- rolling elements for example for the lining changes.
- the flanges have grooves for receiving the lateral extreme edges of the transverse walls. In this way, the transverse walls are fixed to the flanges by simple embedding of their extreme edges in the grooves of the flanges. In addition, a better seal is simply ensured between the hydraulic circuit inside the device, under vacuum, and the basin outside the device.

- Each transmission cassette 6 is rigidly but removably fixed, in a single unit, respectively at each lateral end 7 of the motor housing 1.
- Each cassette 6 forms a lateral flange extending longitudinally forward and towards the rear of the motor housing 1, so as to form a rigid frame 72 generally in the form of an H on which the other members of the apparatus are attached and fixed, namely an upper cover 5, a handle 8 for maneuvering; front 9 and rear 10 transverse walls extending between the two cassettes 6 and the upper cover 5, and at the front and, respectively, at the rear of the motor housing 1 and delimiting between them and with the cassettes 6, lower part, a lower opening closed by a bottom 11 provided with water inlets 66 with valves authorizing the entry of water upwards but preventing water outlets downwards.
- the bottom 11 carries a filter bag 12 incorporated in the housing 73 thus constituted by the cover 5, the transverse walls 9, 10 and the cassettes 6.
- the filter bag 12 has two pockets extending at the front and, respectively at the rear of the motor housing 1, between the motor housing and each transverse wall 9, 10.
- the front 9 and rear 10 transverse walls are provided, at their lower part, with non-return drain valves 74 adapted to prevent the entry of water from the outside into the housing 73 during operation of the device but for authorize, by gravity, the exit of the water contained in the housing 73 after stopping the device.
- non-return drain valves 74 adapted to prevent the entry of water from the outside into the housing 73 during operation of the device but for authorize, by gravity, the exit of the water contained in the housing 73 after stopping the device.
- the device comprises two front rollers 13 (a left front roller and a right front roller), extending between the two cassettes 6, and at the front of the front transverse wall 9, at the exterior of the hydraulic circuit formed in the housing 73, and transversely and in axial extension of one another, rotating about a transverse axis parallel to the surface on which they roll, each of these front rolling members 13 being coupled, respectively, to one of the lateral cassettes 6; and two rear rollers 14 (a left rear roller and a right rear roller) extending between the two cassettes 6 and at the rear of the rear transverse wall 10, outside the hydraulic circuit formed in the housing 73, and transversely and in axial extension of one another, rotatable about a transverse axis parallel to the surface on which they roll, each of these rear rolling members 14 being coupled respectively, to one of the lateral cassettes 6.
- two front rollers 13 a left front roller and a right front roller
- rollers of the same pair of front 13 or rear 14 rollers are independent of each other, in rotation, that is to say integral in rotation, each of them being driven by one motors 83 (left or right), to the motor shaft 2 (left or right) from which it is connected by a transmission cassette 6.
- Each roller 13, 14 comprises a main cylindrical shaft 17, and a peripheral lining 18 for example made of foam and / or formed of brushes, mounted for rotation with the shaft 17, but which can be replaced in the event of wear.
- the shafts 17 of the two front rollers 13 or rear 14 are cylindrical of revolution and telescopic one inside the other axially so that they can be brought together in the central part of the apparatus to be uncoupled from the lateral cassettes 6 and dismantled from the device, or, on the contrary, be distant from one another in order to couple them to the cassettes 6.
- the shafts 17 of the rollers 13, 14 are also guided by a central bearing 15, 16 secured to the front wall 9, disposed between the two front or rear 13 or rear 14 rollers.

- the two rear rollers 14 are similar to the front rollers 13, with a transverse axis parallel to that of the front rollers 13, and mounted and driven similarly to the front rollers 13.
- the bearings 15, 16 integral with the transverse walls 9, 10 guiding the rollers 13, 14 undergo little effort radially.
- rollers 13, 14 define a rolling plane of the device corresponding to the submerged surface on which it moves.
- the motor shafts 2 of the device are coaxial and parallel to this running plane.
- the pumping shaft 71 of the third motor driving the propeller 3 is orthogonal to this running plane, so that the propeller 3 is adapted to create a flow of water in the orthogonal direction away from the running plane ( vertically upwards when the submerged surface is horizontal) from the lower inlets 66 around the motor housing 1 and between the transverse walls 9, 10, the cassettes 6 and the motor housing 1, and up to an upper discharge orifice 4 formed in the upper cover 5 of the device through which water is discharged from the device upwards.
- the filter bag 12 extends at the front and at the rear of the crankcase 1 and its opening is associated with the periphery of the bottom 11 so that this filter bag 12 is interposed on the water circuit between inputs 66 and outlet 4.
- the casing 1 can be molded as close as possible around the motors 70, 83 and the bodies which it contains, for the benefit of a smaller footprint, an increase in rigidity, and hydrodynamic rounded external shapes.
- the propeller 3 When the propeller 3 is active, the water is driven in upward movement and therefore cannot escape through the drain valves 74 by gravity.
- a sealed electrical power cable 19 is connected to the inside of the motor housing 1, for supplying and controlling the various motors 70, 83, and this cable 19 passes through the upper cover 5 through one of the lights 79 of fixing the handle 8 so that it can be connected to a source of electrical power external to the device and to the swimming pool.
- the two side cassettes 6 are identical. In fact, each cassette 6 has symmetry with respect to a transverse median plane orthogonal to the running plane and therefore to the surface on which the device moves. This plane of symmetry is thus in particular vertical when this surface is horizontal.
- the frame 72, and more generally the apparatus, are generally symmetrical with respect to the same median transverse plane orthogonal to the rolling plane, and this plane of symmetry of the robot coincides with the plane of symmetry of each cassette 6.
- Each transmission cassette 6 comprises an external rigid casing 20 (the other elements of the cassette 6 being incorporated in this casing 20).
- This casing 20 is formed by two half-shells 20a, 20b including an internal half-shell 20a closest to the motor casing 1 of the device, fixed to the motor casing 1 of the device, and an external half-shell 20b la further from engine crankcase 1 of the device.
- Each half-shell extends at least substantially orthogonally to the running plane and in the longitudinal direction, and the two half-shells 20a, 20b are assembled to one another along a generally longitudinal peripheral plane 21a, 21b.

- the cover 5 is provided with slots 79 allowing the passage of the hooks 77 through the cover 5, and the insertion of locking jumpers 80 adapted to lock the hooks 77 in the hooking position.
- Each light 79 of the cover 5 is larger than the hook 77, so that a locking jumper 80 can be inserted in this light 79 at the rear of the hook 77, between the hook 77 and the edge opposite the light 79 to push the hook 77 laterally into the hooking position with the bracket 22.
- the jumpers must be removed from locking 80 by extracting them axially from the slots 79 of the cover 5, which makes it possible to push the hooks 77 laterally into the slots 78 of the brackets 22 and into the slots 79 of the cover 5, to release them from the brackets 22, then extract them axially out of these lights 78, 79.
- the reverse operations are carried out.
- the handle 8 is thus fixed on the brackets 22 of the cassettes 6, therefore on the frame 72, through the cover 5 in a removable manner. It should be noted that this fixing of the handle 8 to the frame 72 also secures the cover 5 to the frame 72, the hooks 77 and jumpers 80 having an external part larger than the lights 79 of the cover 5 so that the cover 5 is maintained against the brackets 22 of the cassettes 6.
- the internal half-shell 20a also comprises two lower lateral brackets 24 also extending transversely towards the center of the device to be placed above a lower lateral flange 25 of the crankcase 1 and to be fixed thereto by screws 26.

- the different pinions can thus be identical, for the benefit of a manufacturing economy.
- each of the output pins 33, 34 is also rotated in the same direction and at the same speed by the pinion trains 48, 49.
- the axes of rotation of the various pinions 48, 49 may simply be formed by cylindrical transverse extensions 53 adapted to receive a cylindrical bore of the various pinions, these extensions 53 extending outward from the half internal shell 20a of which they are integral.
- the two internal half-shells 20a and external 20b are assembled to one another by screws 54 passing through the axes of rotation of the
