Definitions

  • This invention relates to suction cleaner nozzles and particularly to a novel multi-purpose nozzle capable of being readily adjusted for cleaning different types of surfaces.
  • Multi-purpose nozzles for suction cleaners capable of being adjusted to clean such differing surfaces as rugs and hard floor surfaces are well known and have achieved wide commercial success.
  • a particularly advantageous form of such nozzles provides both a first working member, such as a rigid nozzle body having a mouth with smooth edges adapted for engagement with the surface of a rug, and a second working member, such as a brush adapted for better engagement with a hard floor surface, in combination with means for effecting relative adjustment between the two members so that either can be brought into play. While prior art workers'have proposed many constructions of this general type, including various adjusting means by which the desired working member can be selected, these have not proved'entirely satisfactory in commercial use, and there hasbeen a continuing need for improvement.
  • An object of the invention is to provide an improved multi-purpose suction cleaner nozzle, of thetype comprising at least two different working members, characterized by novel and more effective means for accomplishing relative movement between the working members to bring the same selectively totheir positions of use.
  • Another object is to devise such a nozzle wherein the desired adju'stmentis accomplished by selectively depressing either of apair of foot .pedals or the like.
  • a further object is to provide such a nozzle including novel means for accomplishing both relative adjustment of the working members and locking of the same in adjusted position.
  • FIG. 1 is a bottom view of a suction cleaner nozzle constructed in accordance with one embodiment of the invention, with parts broken away;
  • FIG. 2 is a partial verticalsectional view of the device of FIG. 1, looking forwardly and taken transversely of the normal line of travel, some parts being shown in elevation;
  • FIG. 3 is a top view of the device of FIG, 1, with parts broken away for clarity;
  • FIG. 4 is a vertical sectional view taken on line 4--4, FIG. 1;
  • FIG. 5 is a vertical sectional view taken on line 55, FIG. 2;
  • FIGS. 6 and 6A are fragmentary rear elevational views, with parts broken away for clarity, showing certain elements of the device of FIG. 1 in two different adjusted positions;
  • FIG. 7 is an exploded view illustrating the adjusting mechanism of the device of FIG. 1;
  • FIGS. 8 and 8A are two fragmentary front elevational views of the device of FIG, 1, with some parts shown in vertical section, illustrating the adjusting mechanism in its two extreme positions, and
  • FIG. 9 is a bottom view of a brush constituting one of the working members of the device of FIG. 1.
  • the embodiment of the invention here illustrated comprises a hollow main nozzle body A formed by a member 1, normally the top, and a member 2, normally the bottom, secured together in any suitable fashion, as by screws at 3, FIG. 3.
  • member 1 has a raised central portion 4, laterally extending portions 5 and a dependent peripheral lip 6. As best seen in FIGS. 2 and 3, portion 4 of member 1 is provided with a centered inlet opening 7, the edges of which are defined by a depressed portion 8. Ribs 9 extend forwardly and rearwardly from inlet opening 7.
  • Member 2 includes a flat wall 10, provided with an elongated inlet opening 11, FIG. 1, which extends for most of the long dimension thereof, and also includes an upstanding peripheral flange 12 engaged with lip 6 of member 1, Wall 10, normally at the bottom of the device, is provided with a plurality of elongated openings 13 spaced apart from each other and also spaced inwardly from the outer edge of wall 10. Openings 13 are separated by solid areas 14 of wall 10.
  • An outlet conduit member 16 extends through opening 15 and has an angul-arly offset, open outer end 17, adapted for telescopic connection with the usual tubular handle (not shown), and an inner end closed by a slanting partition 18 and a transverse end wall portion 19, as seen in FIG. 5.
  • Adjacent end wall portion 19, member 16 is provided with a lateral inlet opening 20 so disposed as to communicate either with inlet opening 11 of member 2, as described hereinafter, or with inlet opening 7 of member 1, depending upon the rotational position of conduit member 16 with respect to body A.
  • conduit member 16 connected to the usual suction cleaner, air can be drawn either through inlet opening 7 or inlet opening 11, as the operator desires.
  • the intermediate portion of member 16 is cylindrical and there is also provided a portion 21 extending forwardly from partition 18, so that the entire portion of member 16 disposed within body A presents a smooth, cylindrical surface which is interrupted only by opening 2%).
  • Partition 18 has, formed integrally therewith, a forwardly extending boss 22 with a cylindrical tip portion 23, of reduced diameter, and a forwardly directed threaded bore 24.
  • a sleeve 25 including a cylindrical bore 26 which is open at the rear and closed at the front by an end wall 27 provided with a centrally disposed, circular bearing opening.
  • bore 26 of the sleeve embraces the forward portion of member 16, and cndwall 27 extendsacross the front end of member 16, with tip portion 23 of boss 22 extending through the bearing opening in wall 27.
  • Sleeve 25 is retained on member 16 by a screw 28 threaded into bore 24 of boss 22.
  • Member 2 is provided with wall means 29, FIGS. 1, 4 and 5, defining an elongated channel of which opening 11 is the mouth, such channel increasing in depth toward the center of the nozzle and serving to confine the flow of air entering via opening 11.
  • wall means 29 can form an integral part of member 2 and extend from the ends of opening 1 1 to the side areas of sleeve 25.
  • Sleeve 25 may thus be considered as having a lateral opening, indicated at 30, FIG.
  • opening 7 of member 1 in which case the cylindrical wall of sleeve closes opening 30.
  • Member 2 is also provided with an upstanding partition 31, as seen in FIG. 4, spaced inwardly from flange 12.
  • member -1 is provided with a dependent partition 32, FIG. 4, spaced inwardly from peripheral lip 6 and disposed in engagement with the top edge of partition 31.
  • the partitions-31, 32, flange 12 and lip 6 combine to define an area within body A to accommodate a defining an elongated rectangle, so as to include two parallel portions 36, 37, FIGS. 7 and 9, of substantial length, the portion 36 being interrupted as shown to accommodate the conduit 16 and certain parts associated therewith.
  • Cross braces 38 are advantageously formed each from a single piece of sheet material and have end portions 39 which embrace the frame 34 in clamping relation.
  • Each end portion 39 includes a portion 4! lying against what can be termed the inner face 41 of brush frame 34, as seen in FIG. 7, and each such portion connects with an ear 42 forming part of the brace and extending at right angles to the long dimension of the brush.
  • Ears 42 are joined by main body portion 43, a portion of the cross brace lying generally parallel to the plane of frame 34 and disposed slightly above the top edge of frame 34.
  • Each ear 42 is provided with an opening 44 facing in the direction of the long dimension of the brush.
  • an actuator 45 comprising a cylindrical tubular portion 46 extending through opening 15 and disposed behind the open rear end of sleeve 25, as will be clear from FIG. 5.
  • the outer diameter of portion -17 of conduit member 16 is advantageously made larger than for the remainder of member 16, so as to provide a forwardly directed shoulder 47, portion 46 of actuator 45 thus being retained between shoulder 47 and the open end of sleeve 25.
  • actuator 45 Rearwardly of body A, actuator 45 is provided with a pair of integrally formed foot pedals 48, 49. At the end of portion 46 within body A, actuator 45 is provided with a pair of opposed, laterally projecting cam lugs 54 each having a forwardly opening cam slot 51. Since portion 46 of actuator 45 is capable of rotating with respect to conduit 16, depression of one pedal 48, 49 will cause lugs 50 to swing about the central axis of actuator 45 in one direction, while depression of the other pedal will cause the cam lugs to swing in the reverse direction.
  • actuator 45 is translated into reciprocatory adjustment of brush 33, to retract the same to the inactive position seen in FIGS. 6 and 8 or to project ing transversely and inwardly of the rocker.
  • Each ear 57 is provided with an opening 58 and, as seen in FIGS. 2, 6 and 8, the spring arms 54 extend through, such open ings.
  • the end portions of arms 54 opposite cross i race 38 extend adjacent the inner faces of side plates 55.
  • these end portions of arms 54 are bent outwardly, projecting at right angles to the long dimension of body A, as indicated at 59, extend through aligned openings 60 in plates 55, and are journalled in bearing holes 61, FIG. 1, in partitions 31 of member 2.
  • opposed end portions 59 ofeach pair of spring arms 54 in combination with bearing holes 61, form means mounting the corresponding rocker 52 for pivotal movement about an axis at right angles to the long dimension of body A and also at right angles to the direction of travel of brush 33 between its retracted and projected positions, such axis being parallel to the axis of rotation of the actuator 45 and disposed therebelow.
  • Cam rollers 53 are each carried by a shaft 62 journalled in aligned bearing openings 63 in side plates 55 of rockers 52. .As best seen in FIG. 3, each rocker 52 is disposed immediately in front of cam lugs 50. Bearing openings 63 are located above openings 60 and the relative positions of rockers 52 and cam lugs 50 is such that the cam rollers 53 extend into cam slots 51.
  • Each cam slot 51 is slightly wider than the diameter of rollers 53 and is defined, over most of its length, by straight side wall portions 64 extending generally tangentially with respect to cylindrical body 46 of actuator 45. At its end nearest body 46, each slot 51 ,is provided with a notch 65, defining part of a cylindrical surface of larger diameter than rollers 53, and located on the side of the slot further from body 46. At its end further from body 46, each slot 51 is provided with a notch 66 like notch 65 except located on the side of the slot nearest to body 46.
  • the arrangement is such that brush 33 is elevated, or retracted, when pedal 48 is fully depressed, and-lowered, or projected into operative position, when pedal 49 is fully depressed.
  • both cam rollers 53 are disposed in their appropriate notches 65, these being the notches closest to body 46 of actuator 45. Accordingly, rockers 52 are both held in such position that the portions thereof providing bearing openings 63 are near body 46, the ends of spring arms 54 which are connected to cross braces 38 thus being elevated.
  • both cam rollers 53' are disposed in their respective notches 66. Since notches 66 are the ones most distant from body 46 of the actuator, both rockers 52 are now held in such position that the portion thereof providing bearing openings 63 are removed from body 46, and the ends of spring arms 54 connected to cross braces 38 are accordingly lowered. Between these two extreme positions of the actuator, movement of the cam lugs 50 causes rollers 53 first to ride out of the end notch, then to ride along the appropriate straight wall portion, and then to fall into the opposite end .notch.
  • rockers 52 function as bell crank levers pivoted at 60, one lever arm carrying the cam roller and the spring arms 54 constituting the other lever arm.
  • cam slots 51 provided with notches 65 are aligned across cylindrical body 46 on a diameter thereof and are equally spaced from the central axis of the actuator.
  • the cam slots thus extend tangentially outwardly from like starting points.
  • the outer ends of the cam slots, provided with notches 66, are aligned across cylindrical body 46 and lie on a diameter thereof, the cam slots being of equal length. Accordingly, as the actuator turns on member 16, and rollers 53 follow their cam' slots, the rockers 52 can be con sidered as being both connected to the body of the ac-.
  • cam slots 51 The configuration and disposition of the cam slots 51, the spacing between openings 69 and 63, and the length of arms 54, are such that the pivotal movement of rockers "52 resulting from full depression of one of the pedals is greater than that required to move the brush frame over the distance allowed by the space between portions 14 and member 1.
  • the spring arms 54 are flexed and under tension, as seen in FIGS. 8 and 8A, and the arrangement is such that the cam rollers 53 are held firmly in notches 65 or 66, as the case may be, by the spring force of the arms, so that the brush is latched in its adjusted position.
  • the elongated spring arms 54 are bent crosswise of their lengths in opposite directions from intermediate unbent positions best seen in FIG. 7.
