Filed May 29, 195'? l f l States MULTI-PURPOSE SUCTUN CLEANER NOZZLE G osta Ludvig Hellstrom, Stockholm, Sweden, assigner to Aktiebolaget Electrolux, Stockholm, Sweden, a corporation of Sweden My invention relates to a multi-purpose suction cleaner nozzle which may be employed at will for different types of cleaning operations.

It is an object of my invention to provide an improved multi-purpose nozzle employing a rotatable member which may be intermittently rotated in the same direction in stepwise fashion to render any one of a number of operating surfaces available to perform a specific type of cleaning operation.

Another object is to provide a multi-purpose nozzle of this type in which the rotatable member is firmly held in any one of its operating positions and can be readily rotated in one direction about an axis extending lengthwise of the nozzle inlet opening to progress from one operating position to another.

A further object is to provide a multi-purpose nozzle of this type in which the nozzle body is formed of a plurality of hinged sections which normally are in abutting relation and become momentarily separated when the rotatable member is being moved from one operating position to another.

A still further object is to provide a multi-purpose nozzle of this type in which intermittent rotating movement of the rotatable member is promoted with the vaid of one or more resilient members.

Further objects and advantages of my invention will become apparent as the following description proceeds, and the features of novelty which characterize it will be pointed out with particularity in the claims annexed to and forming a part of this specilication.

For a better understanding of my invention, reference may be had to the following description taken in connection with the accompanying drawings, in which:

Fig. 1 is a front elevation of a suction cleaner nozzle embodying my invention;

Fig. 2 is a bottom plan view of the nozzle shown in Fig. l;

Fig. 3 is a transverse sectional view taken at line 3-3 of Fig. 1;

Figs. 4 to 7 are transverse sections similar to Fig. 3 to illustrate the construction more clearly;

Fig. 8 is a transverse section of a nozzle generally like that shown in Figs. 1 to 7 illustrating another embodiment of the invention;

Fig. 9 is a transverse section, similar to Fig. 6, of the nozzle of Fig. 8 to illustrate details more clearly; and

Figs. 10 and 11 are transverse sections similar to Figs. 3 and 4, respectively, illustrating a further embodiment of the invention.

Referring to the drawings, in Figs. 1 to 3 I have shown a suction cleaner nozzle embodying my invention which comprises an elongated hollow body 10 to an intermediate region of which is connected an upwardly inclined tubular member 11. The tubular member 11 serves as an outlet socket adapted to be connected to a suction line or conduit of a suction cleaner through which air is drawn when the suction cleaner is being operated. The hollow interior of the body provides a passage 12 through which air is drawn toward the outlet socket 11 from the region of an elongated inlet opening 14.

Within the passage 12 is disposed a rectangular-shaped member 15 having elongated side walls 16 and connecting end walls 17. To each of the side walls 16 of member 15 is iixed a row of bristles 18 which, when in the operative position shown in Fig. 3, project downwardly from the nozzle body 10 at the vicinity of the elongated inlet opening 14. Hence, the side walls 16 of the member 15 and the bristles 18 fixed thereto form a pair of spaced apart brushes 19 which are parallel to one another, and which are shown in an operative position in Figs. 1, 2 and 3.

In accordance with my invention, the rectangularshaped member 15 is rotatable in a single direction about an axis extending lengthwise of the elongated inlet opening 14 between positions which make the brushes available for operation, as seen in Fig. 3, and unavailable for operation, as seen in Fig. 7, and may be angularly moved intermittently at will from one position to the other, in either of which it is effectively locked and held. To this end, the nozzle body 16 comprises two halves or sections 2li and 21 which are pivoted at 22 and are movable between the closed position shown in Fig. 3 and the open positions illustrated in Figs. 5 and 6.

The

nozzle body sections

20 and 21 desirably are formed so that when the sections are moved to their closed position, seen in Fig. 2, under the inlluence of a pair of springs 24 connected at their ends to the elongated side walls of the nozzle body 1li, there is a substantially air-tight joint 23 therebetween. The

nozzle body sections

20 and 21 may be provided with a resilient gasket (not shown) in any suitable manner in order to improve ythe seal therebetween.

As shown in Fig. 2, at each end of the member 15 mechanism is provided for holding the member in either of the positions illustrated in Figs. 3 and 7 and for angularly moving the member from one of these positions to the other. In Figs. 3 to 7 I have illustrated the mechansm at only one end of the rotatable member 15, although it should be understood that similar mechanism is disposed at the opposite end of the rotatable member. Each mechanism at either end of the rotatable member comprises two

parts

25 and 26 which are most clearly shown in Fig. 5. The part 25, which bridges the gap across the passageway 12, is secured at its forward end to the front nozzle section 20 at 27. The rearwardly extending portion 25 of part 25 passes through a slot 28 in the rear nozzle section 21 and extends upwardly at an acute angle with respect to the front portion thereof, as best seen in Fig. 43. The rear portions 25 of the parts 25, which may be referred to as actuating levers or pedals, are manually operable to move the

nozzle body sections

20 and 21 against Ithe tension of the springs 24 from the closed positions shown in Figs. 3 and 7 to the open positions illustrated in Figs. 4, 5 and 6.

The part 26 of each mechanism at either end of the member 15 is essentially U-shaped and is formed with an elongated slot 29 which receives aV pin 30 mounted in any suitable manner within the rear nozzle body section 21. Hence, the parts 26 are pivotally mounted on the rear nozzle body section 21 and are angularly movable thereon at regions disposed between the parts 25 and the ends 17 of the rotatable member 15, as best shown in Fig. 2. As shown in Fig. 3, springs 31 are maintained in position between the roof portion of the rear nozzle section 21 and the top arms of U-shaped parts Z6 to bias the bottom arms thereof toward the elongated inlet 14 of the nozzle body 10.

As best shown in Fig. 5, the top edge of each part 25 is notched or recessed to form a pair of spaced apart catches 25a and 25b having a connecting edge portion 25C therebetween. In a similar manner, the bottom edge of the lower arm of each U-shaped part 26 is notched or recessed to forrn a pair of spaced apart catches 26a land 26b having a connecting edge portion 26e therebetween. In the closed position of the

nozzle body sections

20 and 21 illustrated in Fig. 3, the notched or recessed portions of the

arts

25 and 26 are closely adjacent to one another and hold therebetween a pair of spaced apart

pintles

32 and 33 xed to and projecting outwardly from the end wall 17 of the rotatable member 15. The

respective pintles

32 and 33 at opposite ends of the member are in axial alignment to provide a four-point support for the member when it is cradled and held between the notched regions of

parts

25 and 26, as illustrated in Fig. 3.

It will be observed in Fig. 3 that pintle 32 is held in the catch 25b of part 25, while the pintle 33 is held in the catch 26a of part 26, the part 26 being resiliently biased downwardly toward the part 25 by the springs 31 to hold the rotatable member 15 firmly locked in the position rendering the brush available for operation. When movement is imparted to the rearwardly extending portions 25' of the parts 25 to cause the

nozzle body sections

20 and 21 to separate, the catches 25a on parts move forward to receive the pintles 33 and move the latter clear of the catches 26a on part 26, as seen in Fig. 4. Since the gap between the catches 25a and 25b is greater than the distance between the

pintles

32 and 33, the catches 25b are clear of the pintles 32 when the pintles 33 are held in the catches 25a.

As the

nozzle body sections

20 and 21 are being moved apart, the catches 26h of parts 26 are in the path of movement of the pintles 32. The edge portions 25e of parts 25, which serve as tracks or guideways for the

pintles

32 and 33, effectively guide the pintles 32 into the catches 26b of parts 26 and cause the

pintles

32 and 33 to assume the position illustrated in Fig. 4. With further separation of the

nozzle body sections

20 and 21, force is transmitted from the parts 25 through the member 15 to the parts 26 which causes the latter to pivot about the pins 30 against the tension of the springs 31. When the member 15 has been turned about 90 to the position illustrated in Fig. 5, the springs 31 are under maximum tension. The instant the member 15 passes through its upright or dead-center position, the parts 26, under the influence of the springs 31, pivot about the pins 30 and impart movement to the member 15. In Fig. 5, for example, the member 15 is being moved in a counterclockwise direction. As soon as the member 15 passes through its upright or dead-center position, the springs 31 become effective to impart clockwise movement to the part 26 whereby continued counter-clockwise movement of the member 15 is assured.

As counter-clockwise movement is being imparted to member 15 by the springs 31, as illustrated in Fig. 5, further separation of the

nozzle body sections

20 and 21 is being effected. When the separation of the

nozzle body sections

20 and 21 is at a maximum, the catches 26b receive and hold the pintles 32 and the top edge portions 25d of the parts 26 underlie and are in close proximity to the pintles 32.

As the

nozzle body sections

20 and 21 move toward one another from their position of maximum separation,

the catches 2511 receive and hold the pintles 33, while the pintles 32 move on the tracks or guideways 26C toward the catches 26a, as illustrated in Fig. 6. When the

nozzle body sections

20 and 21 again are in abutting relation, the member 15 has completed a half-turn from the position shown in Fig. 3 and is in the position which renders the brush unavailable for operation.

In view of the foregoing, it will now be understood that the rotatable member 15 can be moved from the position which renders the brush unavailable for operation, shown in Fig. 7, to the position which renders the brush available for operation, shown in Fig. 3, by again separating the

nozzle body sections

20 and 21 in the manner described above and illustrated in Figs. 4, 5 and 6. The

pintles

32 and 33 at each end of the rotatable member 15 form a plurality of parts which are spaced from one another in a plane transverse to the longitudinal axis of the elongated inlet 14. Each element 25, having the rearwardly extending portion 25', is disposed in one of the aforementioned planes at an end of the member 15 and movable in a rst direction from a starting point and in a second opposite direction back to the starting point. The catches 25a provided on the elements 25 coact with the parts or

pintles

32 and 33 sequentially on successive movements of the elements 25 in one of the directions to impart angular movement to the member 15. In the embodiment just described, the catches 25a coact with the first and second parts or

pintles

32 and 33 alternatively on successive movements of the elements 25 from the starting point in the first or righthand direction, as illustrated in Fig. 4. When this is done, the rotatable member 15, which is axially immovable within the elongated inlet 14, always rotates in the same direction in the nozzle body 10 from one position to the other. When the member 15 is in the position shown in Fig. 3, the brushes 19 contact and can be moved over a surface to be cleaned, the space between the brushes providing an unobstructed passageway through which air may be drawn toward the outlet connector 11. Likewise, when the member 15 is in the position shown in Fig. 7, the smooth edges of the member 15 form surface engaging lips which can be readily moved over rugs or other pile fabric to effect a cleaning operation.

The notches or recessed regions of the

parts

25 and 26, which face toward one another, form a convenient cradle for holding and supporting the rotatable member in either of its two operating positions, the parts in such case being resiliently biased toward the elongated inlet opening 14 by the springs 31 with the pins 3i) acting as stops. Also, the rotatable member 15, rather than being mounted directly on either of the

nozzle body sections

20 and 21, is carried by the

parts

25 and 26 and rotated about an axis substantially parallel to the major axis of the elongated inlet 14. As will be observed in Figs. 3 to 7, the rotatable member 15 is angularly moved about an axis which is not stationary but shifts from one position to another as the member is being rotated from one operating position to another. Each of the brushes 19 provides an operating surface for performing a particular type of cleaning, the brushes being formed by rows of bristles 13 on the rotatable member 15 which extend lengthwise of the elongated inlet 14. As best seen in Fig. 2, the edges of the

nozzle body sections

20 and 21 at the elongated inlet 14 form front and rear lips of the nozzle body, and each row of bristles 13 is nearer to one lip than the other lip of the nozzle body. As best seen in Figs. 3 to 7, the member 1S bodily moves when it is moved from the posi- ,tion shown in Fig. 3 to the position illustrated in Fig. 7.

In other words, the member i5 is not rotated about an axis which is stationary.

From Fig. 3 it will be seen that the rotatable member 15 in the embodiment just described is of less width than the nozzle passageway 12, so that gaps 34 are formed between the long sides of the member 15 and the front and rear

nozzle body sections

20 and 21. In Figs. 8 and 9 I have illustrated another embodiment of the invention which is generally similar to the embodiment described above and shown in Figs. 1 to 7 and differs therefrom in that the width of the rotatable member is such that the long sides 116 of the member are closely adjacent to the front and rear nozzle body sections 2? and 21. Hence, the rotatable member 115 in the embodiment of Figs. 8 and 9 essentially is in abutting relation with the inner faces of the front and rear nozzle body sections 2) and 21, so that a gap of maximum size is formed between the long sides 116 of the rotatable member 115.

In Figs; 8 and 9 the part 125 is provided with a pronounced bend 35 from whichV the rearwardly extending portion 125 extends obliquely upward at a sharp angle to the portion of part 125 which is disposed between the front and rea-r

nozzle body sections

20 and 21. When the portion 125 becomes a foot-operated pedal which is actuated to separate the

nozzle body sections

20 and 21 from the closed position shown in Fig. 8 to the open position illustrated in Fig. 9, the portion 125 is effective to raise the nozzle body 10 from a floor or supporting surface 36. If the hinged connection 22 in Figs. 8 and 9 were moved forward (to the right), the stationary or rear nozzle body section 21 would be lifted from the supporting surface 36a greater distance than is illustrated in Fig. 9.

In other respects, the embodiment of Figs. 8 and 9 is generally like the first-described embodiment with similar parts referred to by the same reference numerals, Fig. 9 being a transverse sectional view like Fig. 6 in the firstdescribed embodiment.

In Figs. l0 and 11 a further embodiment of the invention is shown which differs from the first-described embodiment in that the part 226 is pivoted at 236 to the rear nozzle body section 221 and acts upwardly, instead of downwardly, on the

pintles

232 and 233 of the rotatable member 215. The rotatable member 215 in Fig. l0 is in the position whereby the brush is available for operation, the

pintles

232 and 233 being cradled in the notched or recessed portions of the parts 225 and 226. Thus, the spring 231, which is retained between an arm of the part 226 and a bracket 237, resiliently biases the notched portions o-f parts 226 toward the notched portions of parts 225 which are fixed at 227 to the front nozzle body section 220. Upon separation of the nozzle body sections 220 and 221, the catches 22661 receive and hold the pintles 233, while the catches 225g act on the pintles 232 and move the rotatable member 215 clockwise to the position illustrated in Fig. ll. When the nozzle body sections 220 and 221 are now moved toward one another, the pintles 232 bear against the edge portions 225e of parts 225 to force pintles 233 out of catches 226e and move them along the tracks or guideways 226e tow-ard the catches 22612, thus completing the turning movement of the member 215 from the position which renders the brush unavailable for operation to the position which renders the brush available for operation. In Fig. l1 it will be seen that the front nozzle body section 220 is provided with a notch 238 that receives a lug 239 on the rotatable member 215 which locks the latter in position when the nozzle body 'sections 220 and 221 are in abutting relation.

If desired, a single rotatable member may be employed which extends from one end to the opposite end of the elongated inlet 14. However, in Fig. 2 it will be seen that the rotatable member 15 is disposed within the passageway 14 and extends lengthwise thereof at an intermediate region of the nozzle body. In addition, rotatable members 15a and 15b may be provided at each end of the rotatable member 15 which are in alignment therewith. The ends of the members 15a and 15b which are closely adjacent to the ends of the member 15 may be actuated bythe mechanism provided at each end of the member 15 by fixing the outer ends of the

pintles

32 and 33 to the connecting end wa-lls of the rotatable members 15a and 15b.

Additional `mechanism may be provided at the outer ends of the members 15a and 15b for moving the latter from the position shown in Fig. 2 to a position in which the brushes are rendered unavailable. However, in the embodiment shown in Fig. l, such additional mechanism is not illustrated since the

members

15, 15a and 15b and connecting

pintles

32 and 33 may be made sufficiently strong so that the mechanism at each end of the member 15 is able to effect movement of all three rotatable members,
