Definitions

  • This invention relates to vacuum cleaner nozzles and particularly to the type which includes an opening or mouth through which the dirt and dust passes, and a brush arranged around such mouth, and includes also an attachment member pivotal in several directions and to which the suction or blower tube of the cleaner is adapted to be detachably connected.
  • An object of the present invention is to provide a nozzle in which the body or so-called mouth portion thereof is provided with an arcuate channel or passage in which the end of the attachment member is fitted and is movably confined. This results in simplicity of construction and assembly, and, since the attachment memher is adjustable in several planes with respect to the mouth portion, a great flexibility in use results.
  • Fig. 1 is a vertical sectional view through a nozzle constructed in accordance with the invention, the attachment member of the nozzle being shown in its normal operating position or the position in which the nozzle appears when cleaning the floor or other articles or surfaces readily accessible from above;
  • Fig. 2 is a sectional View taken on the line 22 of Fig. 1, looking in the direction of the arrows;
  • Fig. 3 shows the nozzle in partial section from the side, the attachment member being shown in its upper position or the position which it assumes when the nozzle is used when cleaning elevated surfaces such as molding, panels or other elevated parts or surfaces;
  • Fig. 4- is a sectional view taken on the line 4-4 of Fig. 3, looking in the direction of the arrows;
  • Fig. 5 shows a vacuum cleaner of the type which has an air tube or conduit to which a so-called brush nozzle made according to the present invention is adapted to be attached.
  • the vacuum cleaner nozzle is made of two main sections, namely, an elastic body member or mouthpiece section preferably composed of rubber or other equivalent elastic material, and an attachment member 11 which is composed of metal or it might possibly be made of plastic.
  • the body member 10 is provided with a lower flared end portion forming a suction opening 12, and
  • the attachment member 11 movably fitted within the body member 10 is provided with a conical sleeve portion 13 to which a suction or air blast tube, shown in dotted lines in Fig. 1, can be connected.
  • the body member 10 of the nozzle is provided with a flared end 14 having the lower end thereof reinforced by a circumferential bead 15.
  • a flared end 14 having the lower end thereof reinforced by a circumferential bead 15.
  • an annular wall of bristles 16 forming a brush.
  • the top ends of the bristles 16 are secured nited States Patent 0 2,710,204 Patented June 7, 1955 in the part 18 of the body member 10, as clearly shown in Fig. l.
  • the head 40 of the brush is thus enclosed and the part 18 of the body member extending about the head 40 constitutes a protective covering to protect furniture against which the nozzle is likely to contact during a cleaning operation.
  • an elongated channel 22 in which the attachment member 11 can be moved in a pivotal and rotative manner.
  • the cross-sectional shape of the channel 22 is essentially circular, as best seen in Fig. 2.
  • the channel 22 appearsas a sector of a circle and thus defines an arcuate passage having an elongated surface portion in which the surface portion of an end of the attachment member 11 is movable.
  • the inner end of the passage 22 is provided with an end wall 23, while the opposite or outer end of the passage is provided with a second end Wall 24.
  • the inner end wall 23 acts to limit the inward swing of the attachment member 11, the limit of which is the position shown in Fig.
  • attachment member 11 and body member 10 are telescopically connected to one another with a section of the attachment member 11 confined and enveloped within the body member.
  • all parts of the attachment member enveloped in the body member move simultaneously in the same direction lengthwise of the axes of the members.
  • the attachment member 11 is arranged coaxially with respect to the channel 22, is swingable from the position shown in Fig. 1 to that shown in Fig. 3, and at its inner end within the body member 10 is formed with a radially extending flange 25 which confines the inner end of the attachment member within the channel 22.
  • the flange 25 engages and abuts the end walls 23 and 24 when the attachment member is in the positions of Figs. 1 and 3,
  • the elongated surface portion or wall of the channel 22 is formed with two shallow plane recesses 26 at diametrically opposed regions thereof, whereby the channel 22 deviates from its essentially circular cross-sectional shape.
  • Opposing projecting parts 27 are .formed at diametrically opposed regions of the flange 25 of the attachment member 11 which correspond in shape with and extend into the recesses 26, such projecting and recessed regions 27 and 26, respectively, providing cooperating tongue and groove parts for guiding the attachment member 11 when it is bodily moved between the end walls 23 and 24 of the body member 10.
  • Regions of the elongated surface portion or wall of the channel 22 are also formed with a pair of diametrically opposed inwardly extending curved ribs 28, and regions of the flange 25 are formed with recesses or notches 29 corresponding in shape to the ribs 28 and received by the latter, such regions 28 and 29 also providing cooperating tongue and groove parts for guiding the attachment member 11 and body member 10 and prevent- 'ing relative angular movement of the members about -channel 22 and terminate short of and below the upper 3 n Wall the d ance et e n the pper n s of the ribs 2.3 and the upper end wall 24 being slightly greater than the thickness of flange 25, as best seen in Fig. 3.
  • the attachment member 11 can then be rotated in a plane at right angles to the plane of the pivotal movement of the attachment member from the position of Fig. l to that of Fig. 3.
  • Such rotation imparted to the attachment member will cause the protruding parts 27 of flange 25 to move out of the recesses 26 and engage the recesses 30 according to the direction in which the attachment member is rotated.
  • This engagement of the parts 27 with the recesses 26 or 39 serves as a stop for locating and holding the attachment member in any selected position to which it is rotated, and it will so hold that position until manually shifted.
  • This pivotal movement of the attachment member 11 enables it to be positioned at various angles.
  • the position shown in dotted lines at the top in Fig. 3 is suitable for cleaning ceilings or other downwardly-directed surfaces, as shown in Fig. 5, while the position shown in full lines, forming more than a 90 angle with the first mentioned position is suitable for cleaning above doors or other elevated upwardly directed surfaces.
  • the intermediate position shown in dotted lines in Fig. 3 is, for example, suitable for cleaning surfaces which are accessible only from the side.
  • the body member 10 may be rigid and formed of metal, for example, and the flange 25 of the attachment member may be formed of rubber.
  • the locking provisions to prevent rotation of the attachment member may consist of projections in the wall of the channel 22 which are received by recesses formed in the flange of the attaching member.
