Lateral transmission casing for a self-propelled running apparatus for cleaning a immersed surface
First Claim
1. A self-propelling rolling swimming pool cleaning apparatus and transmission device for cleaning a submerged surface comprising a motor housing (1) with at least one drive shaft (2) enclosed therein;
- the transmission device, connected to the motor housing (1), transmitting the rotary driving movement of the 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 rigid housing (20), and provided with means (31) for demountable coupling to the at least one driving shaft (2) of the apparatus, likewise the at least one drive shaft being provided with means (32) for demountable coupling mating with the demountable coupling means (31) of the input journal (27), this input journal (27) being adapted to be coupled to the at least one 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 rigid 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 the demountable coupling means 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 rigid housing (20) bearing and guiding the journals (27, 33, 34) and the transmission means (48, 49, 57), anddemountable 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 the at least one 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.
