Lateral transmission casing for a self-propelled running apparatus for cleaning a immersed surface
First Claim
1. A transmission device for a self-propelled rolling apparatus for cleaning a submerged surface, intended for transmitting the rotary driving movement of at least one driving shaft (2), carried by the apparatus, to running members (13, 14, 57) rotatable around transverse axes of rotation in order to drive the apparatus in displacement, which device is formed of a lateral transmission casing (6) comprising:
- a rigid housing (20), an input journal (27) mounted so as to be freely rotatable around an axis of rotation with respect to the housing (20), and provided with means (31) for demountable coupling to a driving shaft (2) of the apparatus, likewise provided with means (32) for demountable coupling mating with those (31) of the input journal (27), this input journal (27) being adapted to be coupled to the driving shaft (2) when the casing is mounted on the apparatus, at least one output journal (33, 34) mounted so as to be freely rotatable around a transverse axis of rotation with respect to the housing (20), and provided with means (41, 42) for demountable coupling to a running member (13, 14), carried by the apparatus, rotatable around a transverse axis of rotation, outside the casing (6), the said running member (13, 14) likewise being provided with means (46, 47) for demountable coupling mating with those of the output journal (33, 34), this output journal (33, 34) being adapted to be coupled to the said running member (13, 14) when the casing (6) is mounted on the apparatus, means (48, 49, 57) for transmission of the rotary driving movement between the input journal (27) and each output journal (33, 34), the housing (20) bearing and guiding the journals (27, 33, 34) and the transmission means (48, 49, 57), and demountable mounting means (22 to 26) adapted to enable the rigid removable fixing, allowing mounting and demounting, of the casing (6) in a single-piece assembly on one side of the apparatus, the input journal (27) being coupled to a driving shaft (2) and each output journal (33, 34) being coupled to a running member (13, 14).

Abstract
A lateral transmission casing (6) for a self-propelled running swimming pool cleaner, comprises a housing, an input shaft provided with elements for removable coupling with a clutch shaft (2) of the apparatus, at least an output shaft provided with elements for removable coupling with a running member (13, 14) of the apparatus, elements for transmitting the powering rotary movement between the input shaft and each output shaft, the housing bearing and guiding the shafts and the transmission elements. Detachable mounting elements enable the casing to be rigidly and removably fixed (6) into a single-piece assembly on the side of the apparatus. The invention also concerns an apparatus equipped with such a casing (6), and its maintenance method.
