Definitions

  • the invention relates to a surface-cleaning apparatus immersed in a liquid, such as the bottom or the side walls of a swimming pool, equipped with at least one removable rolling and / or rotating brushing element.
  • the invention extends to a method of disassembling and mounting the rolling member and / or brushing for the maintenance of said member.
  • Some pool cleaners are of the rolling and self-propelled type: they comprise rotating rolling members about transverse axes of rotation (that is to say perpendicular to the direction of advancement of the apparatus and at least substantially parallel to the surface on which it moves) and driven in rotation about their axis by one or more motors (integrated (s) or external (s) to the device, hydraulic (s) or electric (s), powered (s) by a waterproof electrical wire plunging into the pool).
  • motors integrated (s) or external (s) to the device, hydraulic (s) or electric (s), powered (s) by a waterproof electrical wire plunging into the pool.
  • Some pool cleaners are also equipped with rotating brushing members around transverse axes, intended to sweep the immersed surface to remove any impurities possibly deposited or embedded on said surface. Left free in rotation, these brushing members have only a low efficiency: they rotate as the robot moves without brushing the immersed surface. This is why they are generally driven in rotation by at least one engine via a mechanical transmission, and then also act as rolling members. Consequently, throughout the following, the expression "rolling member” includes brushing members rotated by at least one motor via a mechanical transmission.
  • the rolling members of the known self-propelled moving-wheel cleaning apparatuses are in fact rotated by one or more motor shafts whose rotary movement is transmitted to said members by one or more mechanical transmission devices, for example with gears and / or belts cooperating with at least one axial end of the rolling member.
  • the rolling members are of two types: they are either of the type with rotation shaft projecting laterally from the device (wheels or wheels or side tracks), on the side and therefore easily accessible and laterally dismountable, either of the type to rotation shaft guided at its two axial ends (rollers, center wheel (s), ...) and driven to at least one of said ends, and thus embedded between guide means (comprising means for rotation drive) integral with the chassis of the apparatus (the two axial ends of the rotation shaft are for example each fixed on a bearing or pinion belonging to a gear train lateral transmission of the motor movement).
  • the brushing members are most often of the second type previously described.
  • the document FR2584442 describes a self-propelled liquid-immersed surface-cleaning machine comprising wheels which are driven by a drive and transmission device and which then drives a transverse rolling member.
  • some known devices comprise rolling members composed of a support shaft fixed at both ends to guide means (and drive), and at least one flexible peripheral lining in contact with the ground (foam, brush, etc.) that can be separated from the support shaft without disassembling the support shaft.
  • the lining is in the form of a sheet or strip and / or has, throughout its length, a mounting opening so as to be mounted on the support shaft by winding or wrapping, and then fixing the longitudinal end edges to by means of fastening means provided for this purpose distributed over the length of the lining (peripheral adhesive strips, hooks at the longitudinal edges of the inner cylindrical surface of the lining (surface in contact with the support shaft).
  • these linings have on their inner cylindrical surface means for reinforcing the adhesion of the lining on the shaft (non-slip strips, adhesive, etc.), in order to ensure the drive in rotation of said lining by the shaft.
  • other fittings are made integral with the tree by their mounting method: fixation under constraints, so as to eliminate any play between the lining and the shaft.
  • the object of the invention is to provide a submerged, self-propelled, immersed surface cleaning device whose rolling members are of the extreme double-guiding type, but which are adapted to allow the change of their surface (s). ) without the need to disassemble any part of the chassis or use wrapping or winding fittings for this purpose.
  • the invention therefore aims to provide a self-propelled rolling cleaner whose rolling members are provided with tubular or liningless packing, but whose maintenance, especially in case of wear, is simple and fast.
  • tubular lining a lining having a cylindrical outer envelope of continuous revolution forming a running surface and an axial hollow core, for receiving a support shaft. Without opening of longitudinal assembly, the tubular lining is mounted on the shaft by introduction and axial sliding of the shaft in the central core of the liner.
  • rolling member without lining a rolling member whose support shaft and (or) surface (s) are formed of a single piece and a set of indissociable parts.
  • the invention also aims at providing a self-propelled rolling-cleaner apparatus for which the change of a tubular lining of a rolling member or the change of a bearing member without lining, is a simple and rapid operation being carried out without prolonged immobilization of the device.
  • the invention also aims to provide such an apparatus whose cost, weight, size, performance, reliability and service life are equivalent to those of previous known devices.
  • the guide means are adapted to allow a user to move manually and without tools the rolling member between its working position and its maintenance position.
  • the guide means are adapted so that, in the maintenance position, the rolling member is completely separable from the frame.
  • the guide means are in this case adapted so that, in the maintenance position, the two axial ends of the running member are free, and in particular dissociated chassis guide means (including the chassis drive means).
