Definitions

  • the present invention relates to suction nozzles for use in connection with vacuum cleaners, and more particularly to a suction nozzle having a suction opening the size of which may be altered at the will of the operator.
  • nozzle in which the size of the suction opening may be altered at will and without removing the nozzle from one surface bein cleaned.
  • Fig. 1 is a view of a nozzle in accordance with the present invention attached to a vacuum cleaner unit;
  • Fig. 2 is a bottom view of the nozzle shown in Fig. 1;
  • Fig. 3 is a cross-sectional view taken on the line 3-3 of Fig. 2;
  • Fig. 4 is a cross-sectional view similar to Fig. 3, but showing certain of theparts in a different position; a
  • Fig. 5 is a front view, partially in cross section of the nozzle shown in the preceding figures.
  • Fig. 6 is a perspective view of one of the elements of the afore shown nozzle-
  • reference character III designates a vacuum cleaner unit including a dust bag II and a motor fan unit I2.
  • a vacuum cleaner unit including a dust bag II and a motor fan unit I2.
  • Secured to the inlet of unit III' is a preferably flexible hose I9, the end of which is secured to a rigid hollow handle member II to which is in turn secured a suction nozzle I5.
  • Nozzle I5 includes a member I6 formed with lips II adapted to contact the surface to be cleaned.
  • Member I6 is formed at either end with vertically extending portions I8 between which portions is slidably mounted an elongated member I9.
  • the ends of member I9 are solid, while the central portion thereof is formed with an opening 20.
  • the solid ends of member I9 are provided with grooves 2
  • a spring 23 is also disposed in groove 2
  • Member I9 is guided in its up and down movement by pairs of angularly shaped vertically extending members 24, each consisting of a lug 24' running substantially perpendicularly to the longitudinal axis of member I6 and a wall 24" running between lug 24 and portion I8 in parallel with said axis. Members 24 are secured to or integral with member I6. Members 24 constituting each pair are disposed on opposite sides of member I9 while the pairs of lugs are spaced from each other and from the ends of the member so as to divide the lengthwise extent of the member I6 into three substantially equal sections. The solid end portions of member I9 terminate at lugs 24 and the opening through member I9 is disposed entirely between the lugs.
  • lugs 24' Pivotally mounted between lugs 24' are wall members 25.
  • Springs 26 are secured to the solid end portions of member I9 by means of screws 21, these springs being disposed between the pivoted members so as to tend to maintain them in substantially vertical positions, as shown in Fig. 3, with the upper inner edges of the members 25 in contact with downwardly extending walls 29 integral with the central portion of member I9 and forming part of the boundary of the opening 20 therethrough.
  • This central portion of member I9 is also provided with inclined walls 29.
  • a hollow member 30 is connected to member I9 so as to be pivotable about a substantially horizontal axis.
  • Member 30 has an inner cylindrical surface adapted to rotate on a similar cylindrical surface 3
  • Lateral extensions 32 are integral with member 30 and are received beneath cap members 33 secured to member I9, thus rotatably fastening member 3
  • Member 30 is adapted to receive the end of hollow handle member I4.
  • suction openings 34 are formed at either end of the nozzle.
  • These openings are bounded at the top by member I9 and are bounded at both sides and their outer ends by fixed walls formed by member I 8, their inner ends being open to the passage 20 in member l9.
  • nozzle opening bounded by the pivoted wall members is in direct communication with opening 20, air will be drawn into the nozzle throughout its entire length, thus enabling the nozzle to clean a comparatively wide strip during each stroke of the nozzle.
  • the air fiow through this large opening is sufiicient to remove the ordinary dust and dirt embedded in and adhering to the surface undergoing cleaning.
  • the effective size of the suction opening may be reduced by the operator at will without removing the nozzle from the surface'undergoing cleaning.
  • a body member formed with a suction opening having aportion bounded by fixed wall structure and a portion bounded in part at least by pivotally mounted side wall structure, and means for closing the portion of 'said opening bounded by said fixed wall structure and for moving said pivotally mounted wall structure inwardly towards the center of said opening to reduce the area of the portion of said opening bounded thereby.
  • a body member formed with a suction opening having a portion defined by fixed wall structure and a portion defined in part at least by pivotally mounted side wall structure, and a member displaceably mounted with respect to said body member and displaceable to close the portion of said suction opening defined by said fixed wall structure and to move said pivotally mounted wall structure inwardly towards the center of said opening to reduce the area of the portion of said suction openingdeflned thereby.
  • a body member formed with an elongated suction opening, the end portions of said opening being defined by fixed walls, pivotally mounted walls defining the central portion of said opening, and a member reciprocably mounted with respect to said body member and movable in one direction to close said end portions and to turn said pivotally mounted walls to reduce the area of said central portion.
  • a body member formed ing defined by said fixed wall structure and to move said pivotally mounted wall structure to reduce the area of the portion of said suction opening defined thereby.
  • a body member formed with a suction opening having a portion defined by fixed wall structure and a portion defined in part at least by pivotally mounted wall structure, a member mounted .for movement in a vertical direction with respect to said body member, resilient means urging the movable member upwardly, and a hollow rigid handle member pivotally secured to said movable member for connecting said nozzle to a source of suction and formoving said nozzle on a surface to be cleaned, said handle being adapted and arranged to transmit downwardly directed force to said movable member for moving the latter downwardly to close the portion of said opening defined by said fixed wall structure and to move said pivotally mounted wall structure to reduce the area of the portion of said suction opening defined I thereby.
  • a body member formed with a suction opening having a portion bounded by fixed wall structure and a portion bounded in part at least by pivotally movable wall structure, flow preventing means movable into the portion of said opening bounded by said fixed wall structure, and means for moving said movable wall structure-to reduce the area of the portion of said opening bounded thereby.
  • a body member formed with a suction opening having a portion bounded by fixed wall structure and a portion bounded said opening bounded thereby.
