Description
9~
The present invention relate5 to a nozzle for a vacuum cleaner which is provided w~th a suction conduit for attachment to the vacuum cleaner housing, more particularly the invention relates to a nozzle ~hich provides two working m~mbers, such as a ~rush nozzle and a f-at surface nozzle, either of ~hich can be a~ternatel~ ~rought into contact with the working surface ~y means o~ an actuating member which is mova~le ~etween two positions.
A vacuum cleaning implement having a fixea nozzle and working members movable to and ~rom a working position by means of a device actuated ~y a foot pedal i5 known. Thus, force applied to the foot pedal results in the removal of a blocking mem~ex so that the movab~e working members of the nozzle can become operative.
Another form of a vacuum-cleaner element that i5 known is one that has fixed and movable nozzles that are connected to each other by means of springs adjusted to two stable positions. The fixed nozzles are furthermore connected to both longitudinal side portions of the vacuum cleaning implement, while the movable nozzle is connected with the ~entral portion of the cleaning implement provided with an attachment pipe to a vacuum cleaner. In this construction, the movable nozzle ;s airected ~o a working posikion by depressing the central portion, and it is returned from the working position by depressing one of the side portions o the implement.
Another type of known vacuum cleaning impl~ment of the type hereinbefore described requires that a force is applied on the casing of the implement, whereupon one of the nozzles is to be directed into working po~ition. A force ,~
applied on a pedal arranged in the ca~ing brings the other nozzle into a working position. ~he abo~e described known aevices have a common disadvantage in that two diferent actuating steps are necessitated ~o ~rîng one or the other nozzle into working position. Furthermore, a rather large force is necessary ~or the switching operation.
It is therefore an o~ject of the present invention to o~viate or mitigate the a~ove disadvantages-and simplify the handling ~f a vacuum clean;ng device have two working mem~ers.
According to one aspe~t o~ the present invention there i5 provided a su~tion nozzle for attachment to a suction conduit o~ a vacuum cleaner, ~aid nozzle including a pair of working members, relatively movable to be brought alternatel~ into engagement w~th the ~ork surface by means of an a~tuatiny mem~er, said actuating m~m~er moving between two end positions and constituting~a servo mechanism mounted on said suction conduit remote from said nozzle.
An embodiment o~ the inventLon will now be ; 20 described ~y ~ay of example onLy with reference to the accompanying dra~ings in which:
; FIGURE 1 is a sid~ elevational view partly in section showiny a brush nozzle in its outward position on the workin~ surface, and ; FIGURE 2 is also a sectional view, partly in elevation in which a flat surface is in cont~act with the surface to be cleaned.
The suction nozzle as shown in the drawings comprises a housing 10 in~luding a casing 20 and a~tachment 3~ pipe 16, a flat surf ce nozzle lJ~ and a brush nozzle 12~ In 5~
the central portion oE the flat surface noæzle substantially vertical walls 13 are arranged with their upper edges connected to the casing 20. Thus, the walls 13 form a suction channel 14 to conduct air from a suction opening 15 of the channel 14 to lts attachment pipe 16 connected by wand 17 with a vacuum cleaner. The brush nozzle 12 is movable against the force of a spring 18 between a lower position, which is its working position to an upper, idle position. The spring 18 is located between the upper surface of nozzle 11 and an annular support 12a forming a portion of the nozæle 12.
The wand 17 functions to move the suction nozzle on the working surface. A flap valve 19 is arranged in the wand 17 and is movable to a closed position as shown in Fig.
1 to reduce the flow through suction conduit 14. A flap 21 ;s swingably mounted in the casing 20 by means of a cylindrical hub 22. To the periphery of the hubg one end of a pawl or a stepping hook 23 is connected and lts other, free end lies against a stepping wheel 24, whlch has on its periphery Eour outwardly directed projections 25. In addition, two diametrically opposed cam surfaces 26 are fixed on the stepping wheel 24 to be engageable with the annùlar support 12a. A torsion spring 27 biases the flap 21 to the position shown in Fig. 1, in which position the flap 21 closes the suction channel~14.
The operation of the device is as follows: When no air is flowing through the suction nozzle the valve l9 and the flap 21 are in the position shown in Fig. 1. The flap is actuated by the spring 27 to the closlng position. Air flow through the wand 17 moves the valve 19 to the position .,~ ',~'~,1 shown in Fig. 2, and the flap 21 is pivoted against spring force, due to the negative pressure created in the suction conduit, to the position shown in Fig. 2. As t~e flap 21 is pivoted aga~nst the spr~ng forae, t~e stepping hook 23 is pushed against one of the projections 25 of the stepping wheel 24 and the stepping w~ee~ 24 with its cam surfaces 26 is there~y turned counter-clockwise 90. Consequently, the cam sur~aces 26 mo~e out of engagement ~ith the annular support 12a to take the position shown in Fig. 2 and the 0 spring 18 li~ts the ~rush nozzle to its idle positionl It e noted that during this movement, the flap 21 is maintained in close relations~ip with the casing 20 to provide a sustained ~orce to move t~e wheel 24 through the required distance. To move the ~rush noz~le 12 back to the working position, the flap va~ve ~ is manually closed to prevent flo~ through the suction aonduit 14. The spring 27 moves the flap 21 to the closed position and m~ves the hook 23 into a cocked condition. Upon movement of the flap valve 19 to the open positio~, the air flow will move the ~lap 21 against the spring 27 and rotate the stepping wheel 24. ~he hook 23 engages one of the projections 25 and moves the cam surfaces 26 into engagement with the annular support 12a. The brush nozzle 1~ is mov~d against the bias of the spring 18 into a working position and the flap 21 will be in a position to allow air to flow through the suction passage 14. It will be appreciated that when the motor fan unit of the vacuum cleaner is stopped the flap 21 returns to the position shown in Fig. 1, and carries with it the stepping hook ~3, to position the hook to index the nozzle into the alternative position.
~ s~
The valve 19 is prefsra~ly arranged within the operating shaft of the suction aonduit, and is actuated manually against the force of a spring (not shown) so that it closes the t~rough flo~ area o~ the suction conduit in its end position. The nozzle, itse~fi can ~e provided with means ~or visual indica~ion of the posit~on of the working members 11 and 12 in relation to the working surface.
One advantage of the arrangement according to this invention is that the shifting of the working members of the nozzle can ~e done b~ hand from the operating shaft without cumbersome transmission devices such as wires, hoses, etc.
~urthermore the de~ice has a servo effect, i.e. the actuating force required is considerabl~ smaller than in a directly actuated shifting mechanism.
