  • squeegees Devices for cleaning surfaces, especially windows, are well known, and are usually referred to as squeegees.
  • Such devices usually have a cleaning head, comprising a strip of resilient spongy material and a strip of rubber or plastics, each of which is releasably retained on opposite sides of an elongated mounting strip.
  • the mounting strip is attached to an elongate, usually cylindrical handle, which may be telescopically extensible.
  • the spongy material is used to apply a cleaning fluid, such as detergent, and the rubber or plastics strip on the opposite side of the mounting means is used to remove water.
  • a cleaning fluid such as detergent
  • the rubber or plastics strip may be retained in the mounting strip by means of clamping jaws, or by means of a support channel in the mounting strip.
  • Cleaning devices and squeegees are known in which the mounting means may be moved laterally so that it may be secured in an asymmetrical position relative to the handle, for example U.S. 3,110,052 (Whitman), U.S. 3,892,005 (Berns), and U.S. 4,697,296 (Smahlik).
  • a locking and releasing element is arranged so as to adjust both with the rotation joint and with the handle fitted swivel part of the swivel joint in the locking and release positions.
  • EP 283,811 (Unger Licensing Ltd.) discloses a cleaning head having a protrusion which is articulated to an extension of the handle and having coarse curved teeth which engage a spring-loaded locking lever.
  • EP 95733 (Leifheit Int.
  • G Leifheit discloses a tubular handle with an end fitting terminating in a sphere with a row of teeth extending over an equatorial arc; the sphere fits into a sleeve on the cleaning head and a bush which fits inside the sleeve has a row of teeth which engage the teeth on the spherical end. The bush is pressed against the spherical end by a second bush which is screwed into the sleeve.
  • U.S. 4,407,213 discloses a cleaning implement for cleaning the bottom of a boat while the boat remains in the water, in which the cleaning head is pivotally connected to the handle via a pivot axle passing through aligned pivot apertures in interleaved ears on the cleaning head and on the end of the handle; in an alternative form, first and second handle portions are pivotally interconnected so that the inclination can be set to achieve a desired angle. The angle is locked, for example with a wing-nut.

  • the cleaning head comprises a generally rectangular mounting trip having a wiping blade on one long edge, and preferably a resilient sponge on the other long edge.
  • the wiping blade and sponge may be retained by any conventional means, for example a support channel 0 into which each can slide, or by clamping jaws.
  • the wiping blade and the sponge means are replaceable. More preferably the wiping blade is made of plastics or rubber, and the sponge is resilient plastics material. Optionally the sponge may be abrasive. 5

  • Figures 4 and 5 are respectively side and top elevational views of the second handle portion showing the circumferential slit in more detail.
  • the cleaning device comprises a generally tubular handle 1 and a cleaning head 2 having a resilient sponge 3 and a wiping blade 4 retained by a back plate 5 and a front plate 6 held together by retaining screws 7.
  • One of the retaining screws 7 connects the cleaning head 2 to the third handle portion 8.
  • the screws 7 clamp the two plates 5 and 6 together so as to retain the sponge 3 and wiping blade 4.

  • the retaining means for the sponge 3 and wiping blade 4 could also be integrally formed with the third handle portion 8.
  • Handle portion 8 fits slidingly over the second handle portion 9, which, in turn, fits slidingly over projecting ears 10 on the first handle portion 11.
  • the second handle portion 9 is connected to ears 10 via rivets 12 which form a fulcrum about which first and second handle portions 11 and 9 pivot.
  • the third and second handle portions 8 and 9 are joined by a retaining screw 13 on third handle portion 8 which also forms a rotating means.
  • the cleaning head 2 and third handle portion 8 may be rotated through 180° relative to second handle portion 9 so that either the sponge 3 or the wiping blade 4 contacts the surface to be cleaned.
  • a hemicircumferential slot 14 on the second handle portion 9 engages retaining screw 13.
  • Slot 14 may alternatively be on third handle portion 8, with retaining screw 13 then being on second handle portion 9. In either case, it is necessary only to rotate second and third handle portions 9 and 8 relative to each other.
  • a tension coil spring 15 extending from almost adjacent the cleaning head 2 into the first handle portion 11 provides a biasing means whereby to maintain pressure of the cleaning head on the surface to be cleaned while the angle between the cleaning head 2 and the first handle portion 11 is varied by means of pivoting about the rivets 12.
  • the diameter of the spring 15 is only slightly less than the internal diameter of the body of the handle, so that it fits tightly inside the body of the handle.
  • Figures 4 and 5 illustrate the second handle portion 9 in greater detail.
  • Figure 4 is a side elevational view, showing the hemicircumferential slot 14, and a hole 16 which is present on either side and receives rivets 12 (not shown in this figure) .
  • Figure 5 is a top elevational view of second handle portion 9, showing how a portion 17 is cut away at top and bottom leaving projections 18 which are able slidingly to engage ears 10 on the first handle portion 11, and to be fastened thereto by rivets 12 to form a fulcrum.
  • the sponge 3 may be made of any suitable resilient material, for example sponge rubber or sponge plastic, but may have an abrasive surface.
  • the wiping blade 4 may similarly be either rubber or plastics.
  • the back plate 5 and retaining strip 6, and the handle may be made from any material which can be cast, welded or extruded, for example plastics or aluminium.
  • the fulcrum between the first and second handle portions which in the embodiment illustrated is formed by rivets, may equally be provided by a screw or a bolt and a nut. It is emphasized that this pivot means does not require tightening when the device according to the invention is in use, and thus provides a continuous variation in angle between the cleaning head 2 and the first handle portion 11.

Abstract

Le dispositif décrit, qui sert au nettoyage de surfaces, comprend une tête de nettoyage (12) et un manche généralement tubulaire creux et allongé (1). Le manche comporte une première partie (11) destinée à être tenue dans la main par l'utilisateur, une deuxième partie centrale (9) et une troisième partie (8) portant la tête de nettoyage (12), ainsi qu'un pivot (17) entre la première et la seconde partie, un organe de rotation (13) entre la seconde et la troisième partie et un organe de sollicitation (15) permettant d'exercer une pression avec la tête de nettoyage sur la surface à nettoyer. Un tel dispositif permet de régler continuellement l'angle entre la tête de nettoyage et le manche, ce qui évite à l'utilisateur de se courber pour atteindre les extrémités inférieures de la surface à nettoyer.
