Definitions

  • the vacuum cleaner art has devoted much effort and energy in the direction of improving vacuum cleaner U wds t Pa fl ce nozzles to the end that nozzles be devisedwhich will efiectively clean the various types ,of surfaces which are normally encountered in utilizing vacuum cleaners, particularly in the home.
  • the art has developed some nozzles which are well adapted for cleaning bare floors, and other nozzles which are well adapted for cleaning rugs; however, the art has not satisfactorily treated the matter of providing a nozzle which effectively cleans high pile rugs.
  • some eiiort has been exerted in this direction,- with some exceptions, most of it relates to the provision of an additional nozzle in the form of aseparate cleaning tool.

  • Fig. 9 is a perspective view of a modified vacuum cleaner rug tool.
  • Fig. 1 illustrates an existing vacuum cleaner tool of the type wherein two nozzles are provided on opposite sides of the tool, each being adapted to clean a diiierent type of surface, and a swivel tube is associated therewith so as to selectively place either nozzle into contact with the sur-- [face and into communication with the interior of the tube.
  • the existingvacuum cleaner tool 16 is illustrated as being formed of a body having a bare floor cleaning nozzle 12, which is shown as being in contact with a floor surface, and a rug cleaning nozzle 14,,which is shown as facing upwardly and, therefore, not being in contact with a floor surface.
  • the swivel tube 16 is constructed and connected with the body of the tool in such a manner as to be pivotal relative thereto and to allow one or the other of nozzles 12 or 14 to be placed into contact with the surface and into communication with the interior of the tube. It will be understood that the tube 16 is connected with an appropriate vacuum cleaner'hose or tubing so as to be connected to a source of suction.
  • the vacuum cleanertool described thus far is an example of an existing vacuum cleaner tool to which an attachment which incorporates the present invention may be temporarily secured to convert the rug cleaning nozzle from one which is adapted to clean low pile rugs to one which is adapted to clean high pile rugs. It should be clearly understood that the novel attachment contemplated by the instant invention may be used in conjunction with other known vacuum cleaner tools, and its .use is not limited to any type of tool, such as the dual nozzle tool j illustrated.
  • the rug cleaning nozzle 14 generally comprises walls which form a forward lip 18 and a rearward lip 20 between which isformed the elongated nozzle cavity 22.
  • Arow of. bristle tufts 24 ismounted on each lateral side of .the rearward lip 20.
  • the rug cleaning nozzle 14 When the rug cleaning nozzle 14 is utilized on the surface of a low pile rug, it operates to effectively and efiiciently clean it. However, when the rug cleaning nozzle 14 is used on a high pile rug, several operational difiiculties occur which result in diflicult and inefiicient operation. For example, because the nap of a high pile rug is subject to packing, it does not remain fluffy or resilient when being cleaned, and has a tendency to seal oif the nozzle lips. This tendency is accentuated by the fact that most known .high pile rugs have a very thin and flexible backing, such as a layer of'latex.
  • an attachment 25 which incorporates the instant invention, is temporarily secured to the rug cleaning nozzle 14 to temporarily convert it into a rug cleaning nozzle which eifectively and etficiently cleans high pile rugs.
  • Such an attachment is illustrated in Figs. 3, 4 and 5 by itself. In Fig.
  • the attachment comprises an elongated, substantially fiat wall 26 having a plurality of spaced, parallel, elongated, straight slots 28 formed therein and extending in a'direction which is generally normal to the direction of the greatest dimension of the attachment, a centrally disposed, large opening 30 formed therein, and a plurality of spaced, parallel, straight slots 32, which are generally parallel to slots 28, formed on opposite sides of the opening 30.
  • Fig. 1 the attachment comprises an elongated, substantially fiat wall 26 having a plurality of spaced, parallel, elongated, straight slots 28 formed therein and extending in a'direction which is generally normal to the direction of the greatest dimension of the attachment, a centrally disposed, large opening 30 formed therein, and a plurality of spaced, parallel, straight slots 32, which are generally parallel to slots 28, formed on opposite sides of the opening 30.
  • the flat wall 26 is the bottom wall of the attachment which is formed by "a thin sheet of material having the ability tospring slightly, which also forms side walls 34 that are generally perpendicular tobottom wall 26, and that the referred-to slots and opening completely penetrate the material.
  • the slots (of course only slots 32 are illustrated in Fig. 5, but what is about to be said applies equally to the slots 28) extend around the side edges of the bottom wall 26 and upwardly partially into the upstanding side walls 34 of the attachment to a height above the top of the bottom wall 26.
  • a plurality'of oppositely extending nipples 36 are provided on the upstanding side walls 34.
  • the nipples are tapered and cooperate with portions of the existi'ng vacuum cleaner tool to temporarily secure the attachment in the rug cleaning nozzle 14, as will become apparent. From'Figs. 3, 4, 5 and 7, it will be located in the upstanding walls of the sole plate and cooperate with said nipples to permit easy insertion and removal of portions of attachment 25 into and out of the rug cleaning nozzle 14.
  • the tapered configuration of thenipples facilitates such insertion and removal.
  • the attachment 25 is secured to the nozzle by aligning the nipples 36 with the openings 42 and then snapping the attachment into place.
  • the nipples 36 are disposed in the openings or depressions 42. Because of the resilient nature of the material of which the attachment 25 is made, insertion and removal of portions of the attachment by snapping them into and out of the rug cleaning nozzle 14 is facilitated. Also, because the attachment is symmetrical, it is not necessary to orient it in any particular manner "before securing it to the nozzle, hence, it cannot be improperly secured to the sole plate 38 inadvertently.
  • Figs. 2 and 6 illustrate an existing vacuum cleaner tool having an attachment incorporating the instant invention secured thereto. It will be observed in Fig. 2 that when the attachment is secured to the existing tool 10 and placed on surface S, the wall 26 of the attachment 25 makes :planar contact with the surface S, and no part of the rug cleaning nozzle 14 contacts the surface S, other than the strips 24 of bristle tufts. To clean a high pile rug, the
  • the central opening 30 is suitablylarg'e to allow the passage of rather large articles, such as toothpicks, hairpins, cigarette butts and the like, into the nozzle, whereas the slots 28 and 32 operate to remove litter from the surface of high pile rugs, and to remove a suitable amount of embedded dirt.
  • the slots 28 and 32 may seal against the rug. This obtains, because the slots 28 and 32 extend partially into the upstanding side walls 34 of the attachment. Therefore, even though the wall 26 is pressed into planar contact against a high pile rug surface, a seal will not be created, because air will leak into the nozzle through the portions of the slots 28 and 32, that extend into' the upstanding side walls 34. These same portions of the slots while being of sufficient height to prevent the creation of a seal, are not high enough as to allow enough leakage into the nozzle to effect the operating vacuum and air velocity to the point that dirt pickup efficiency is lost.
  • the dimensions of the slots 28 and 32 are also such as to prevent loops of high pile rugs "from being drawn into the nozzle, and yet not sorestrictive as to prevent the entry of a sufficient amount of cleaning air. .
  • the slots function to perform a combing action on the high pile rug surface and provide a pleasing appearance on the rug surface after the attachment has passed over it. The attachment seems to fiuif up the rug pile and help it regain its resilient
  • the attachment was shapedsubstah'tially In one working model of the-attachment 25 whichfwas V 'as illustrated in Figs. 3, 4, 5 and 7, and had a width at its central portion of approximately 1".
  • the central open-' ing 30 was substantially rectangular and had the dimensions of 1.76" by .38" and the slots 28 measured .068" wide by .12" deep (in the upstanding side walls) and were as long as the width of the attachment where they are located.
  • Each of the slots 28 was separated by a strip of the sheet material which forms the surface 26 of the attachment which was .12 wide and very thin (considerably less than .12").
  • the foregoing dimensions represent one dimensional relationship which was found to be highly successful in practice. It will be understood that other attachment shapes and dimensional relationships will also function satisfactorily, so-long as the functional performance of the attachment is as set forth above.
  • Fig. 8 illustrates a modified attachment 25' wherein the corresponding elements to those in the Figs. 1 through 7 modification are indicated by similar reference numerals with a prime added.
  • the only difference between the Figs. 1-7 and Fig. 8 modifications is that the Fig. 8 modification does not have a flat surface which contacts the rug surface, but rather a smoothly curved, upwardly concave wall 26'.
  • Fig. 9 illustrates a complete, high pile rug tool.
  • the preferred embodiment of the invention resides in the Fig. 1 through 7 version, wherein the inventive concept is incorporated in an attachment which may be selectively secured to an existing cleaning tool to temporarily render the latter capable of efficient utilization as a high pile rug, cleaning tool, and which may be removed when it is desired to clean other types of floor surfaces.
  • One reason for preferring the Pigs. 1-7 modification is that it has the practical advantage of affording the benefits of a separate high pile rug cleaning tool without requiring the addition of a separate tool to an already large number of cleaning tools.
  • the complete rug tool 50 is illustrated as comprising a body having a flat wall 52 which is adapted to be placed contiguous with a high pile rug to be cleaned, and which includes a plurality of slots 54 and 56, and an enlarged opening 58, all of which are similar to the corresponding elements formed in the wall 26 of the attachment 25 of the Figs. 1-7 modification.
  • the wall 52 may have an offset portion 60 on which may be mounted strips 62 of bristle tufts.
  • a connector tube 64 is connected to the body of the Fig. 9 rug tooland adapted to be connected to a source of suction.
  • a rug cleaning nozzle is provided which is highly effective on high pile rugs.
  • the rows of bristle tufts extend to about the plane of the surface of the wall of the attachment 25 or tool 50 which contacts the high pile rug.
  • the bristle tuft supporting portions are spaced above the surface being cleaned during operation, and the rows of bristle tufts operate in a known manner to assist in dislodging and removing litter.
  • the row of bristle tufts may already be incorporated in the rug cleaning nozzle. It is, therefore, solely necessary to design the attachment 25 so that it projects from the rug cleaning nozzle to the extent that the plane of its wall 26 passes substantially through the tips of the bristles in the rows of bristle tufts.
  • the rows of bristle tufts may be provided in the rug tool and likewise will extend substantially to the plane of the surface 52.
  • An attachment for insertion into a vacuum cleaner nozzle comprising a substantially flat wall that is adapted to be disposed substantially horizontally to contact a floor surface to be cleaned, upstanding side walls connected to said surface contacting wall at the periphery thereof and being substantially perpendicular thereto, and a plurality of spaced, parallel, narrow, straight slots formed in said surface contacting wall; said slots extending completely through said surface contacting wall between said side walls, and said slots also extending partially into and through said side walls to a height above the top of said surface contacting wall.
  • An attachment for a vacuum cleaner nozzle of the low rug pile type which has a nozzle opening
  • said attachment comprising a thin walled flexible member that is adapted to be secured to the nozzle so as to cover the nozzle opening thereof, said attachment having a bottom wall that is adapted to contact a floor surface to be cleaned, said bottom wall being smoothly curved so as to be concave in an upward direction, upstanding side walls connected to said bottom wall at the periphery thereof, and a plurality of spaced, parallel, straight, narrow slots formed in said bottom wall and extending completely therethrough between said side walls, said slots also extending partially into and through said side walls to a height above the top of said bottom wall.
  • An attachment for selective use with a rug cleaning nozzle of the type which is well suited for cleaning rugs of the low pile type and which has a forward and a rearward lip which co-operate to define a nozzle cavity said attachment being adapted to be temporarily secured to the nozzle by having portions mounted in said cavity to thereby convert said nozzle to one which is well suited for cleaning high pile rugs, said attachment comprising a substantially fiat bottom wall that is adapted to be spaced from the nozzle lips when the attachment is secured to the nozzle, and to be disposed substantially horizontally to contact a high pile rug, and upstanding side walls connected to said bottom wall along its periphery and being substantially perpendicular thereto, a plurality of spaced, parallel, narrow, straight slots formed in said bottom wall, said slots extending completely through said bottom Wall between said side walls, said slots also extending partially into and through said side walls to a height above the top of said surface contacting wall, whereby the portions of said slots which extend partially into said side walls prevent complete sealing of said attachment to said
  • a device as defined in claim 5 wherein said attachment is operatively associated with such a nozzle and a plurality of nipples are formed on said side walls, and a plurality of recesses are formed in said cavity, and said nipples and recesses are located so that said nipples are adapted to be received in said recesses when said upstanding walls are snapped into said nozzle cavity.
  • a device as defined in claim 4 wherein an opening garages ment is operatively associated with such a nozzle and a row of bristle tufts is disposed on said rearward lip, said tufts extending substantially to the plane of said bottom wall when said attachment is secured to said nozzle.
