Description
` 1~8'73~
' The inyention re~ates to a, handle and ~ui:de shaft for floor ma~ntenance appli.ance~., It is known to form these handle $h.afts from two or more telescoping tube portions, The tube portions are then secured against each oth.er ei:th.er by conical end pieces which tighten upon each other or ~y means of spring loaded knobs wh~ch are adapted to enter an opening in the tube portions.
This kind of structure is., h.o~ever, useful only if - , the tube portion~ have about the same diameter or ~f only certain end pieces of the tube portions have a lower diameter.
This is a substantial disadvantage since tube portions with the same diameter cannot be telescoped into each other or, if they have a different diameter, it is difficult to secure them to each other.
It is also known to secure the different tube portions by means of slotted end pieces and coupling nuts with slanting : fastening surfaces. The tube portions are secured by means of the coupling nut and thus attached to each other.
In these cases it is a defInite shortcoming that the ' 20 coupling nut has to be tightened with a substantial amount of force ~, since, when the appliance is used there occur automatically forces in the longitudinal direction of the guide shaft wh.ich push the tube ;~
portions into each other if the attachment is not sufficiently secure.

means of a knob extending from outwa~ds of the oute~ tu~b~pg t~ough the inner tubing and being copnected with the locking mem~e~.
With specific reference now to the embodiment of FIG. 1 it will be seen that a vacuum cleaner 31 is provided w~th the guide and handle shaft 32 and that the telescopic shift~ng of the tubular portions of the shaft can be effected by a release knob 15 which will be further described below. The inner position of the guide shaft is shown in broken lines. This illustrates that the guide shaft can ~;
```:
be adjusted in any manner required by the work.
:
The following Figures 2 to 7 illustrate the mechanical features of the telescopic portions of the guide shaft.
' With reference to FIGS. 2 and 7 ;t will be seen that the inner tube portion 1 is movable in the outer tube portion 2. The `
device is provided with two caps 3 and 4 of which one rests on the inner wall 5 of the inner tube portion while the other rests on the ~-outer wall 7 of the outer tube portion. Both caps extend beyond the ends of the respective tube portions 6 and 8.
The details of the functtoning of the telescoping shift in a preferred embodiment will be illustrated below when describing FIG. 6. At this place it is noted that in FIG. 2 the cap 3 is pro-vided with an actuatlng member ~ which has slanting sides 16 aga~nst which the plungers 10 and ll rest under the action of springs 17.
The plungers extend through openings 12 and 12' in the cap 3 and openings 13 and 13' in the inner tube portion and come to a stop in the outer tube portion 2.
The device operates as follows. ~hen the actuating member 9 moves by means of the actuating rod 14 in the Y-direction as furhter shown in F~G. 3, the plungers 10 and ll move along the slanting surfaces 16 and are forced inwardly by the spr;ngs 17.
They then release the tubular portions l and 2 from each other. The .
~L0873~6 r 1 tube portion 1 thereupon can be moved both in the X- and in the Y-direction.
The spring 22 which is provided on the actuating rod 14 is compressed when movement ~n the Y-direction is effected. It then pushes the actuat~ng member 9 in the X-direction so that its slanting sides 16 abut against the plungers 10 and 11 ~hich now are pressed against the outer tube portion 2 and after moving through the open-ing 34 are pushed into this tube portion and thus secured in posi-tion. In this manner various lengths of the guide shaft can be ob-tained.
F~G$. 4 and 5 show a slightly d;fferent embodiment in which the actuating member 9 is provided with guide notches lB. A
cap 3 is again provided in the inner tube portion 1 and a cap 4 in the outer tube portion 2. The actuating member 9 is again provided with an actuating rod 14 in the same manner as in the embodiment of FIGS. 2 and 3. However, the plungers 10 and 11 engage the actuating member 9 by cams 19 which move in the guide notches 18. Upon moving the actuating rod i4 into the position as illustrated in FIG. 3 the device of FIG, 5 operates as follows;
If the rod 14 is moved against the action of the spring 22 the notches 18 are caused to move along the plungers 10 and 11 so that the cams 19 are moved closer to each other and the plungers move inwardly. This causes the plungers to be freed of the openings 34 and thus the tube portions 1 and 2 are released for movement. Since the spring 22 in the same manner as in FIG, 2 acts to force the ac-tuating member deeper into the cap 3 the notches 18 and the cams 19 also move and cause the plungers 10 and 11 to be pushed outwards when they are fixed aga~n in their posit~on as soon as they become align-ed with the openings 34.
In this embodiment there is also pro~ided rearwardly of .. ,. , :
1~373~6 1 the cap 3 a U-shaped lockin~ member 26 ~hich ~ th~e ~os~tion whe~e the tubular port~ons 1 and 2 are furthest p~lled apart will enter with its latch 27 through opening 28 in the inner tube portion 1 and further into the rçcesses 2~ provided ~n the outer tube portion.
Thus, a complete pulling apart of the tw~ tube portions cannot take place.
In order to ~ntentionally separate the two tube portions~
completely, it is, however, possible to depress the knob 30 whereby the tube port~ons are released aga~nst each other.
FIG. 6 shows in section the handle 33 where there is provided a release knob 15 which extends into a sleeve 36 of the ac~
tuating rod 14. The knob 15 is arranged slidingly in the outer tube portion and in the handle so that it serves to move the actuating rod back and forth.
FIG. 7 in an enlarged section shows again the function of the caps and the interlocking arrangement of the two tube portions.
The cap 4, which is provided on the outer face 7 of the outer tube portion 2, has a bent-back front portion which envelopes the end por-tion of the outer tube, and with its bent-back flange abuts the in-ner tube 1.
The cap 3 (not shown in this Figurel also extends inthe space between the two tube portions and thus improves the guide action. Since the bent-back ends of the two caps, such as end por- - .
tion 35 of cap 4 are elastic and have a tendency to exert an outward pressure, but on the Qther hand may also be pressed together, there is compensation for any deviations in the two tube diameters.
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims.

means of a knob extending from outwa~ds of the oute~ tu~b~pg t~ough the inner tubing and being copnected with the locking mem~e~.
With specific reference now to the embodiment of FIG. 1 it will be seen that a vacuum cleaner 31 is provided w~th the guide and handle shaft 32 and that the telescopic shift~ng of the tubular portions of the shaft can be effected by a release knob 15 which will be further described below. The inner position of the guide shaft is shown in broken lines. This illustrates that the guide shaft can ~;
```:
be adjusted in any manner required by the work.
:
The following Figures 2 to 7 illustrate the mechanical features of the telescopic portions of the guide shaft.
' With reference to FIGS. 2 and 7 ;t will be seen that the inner tube portion 1 is movable in the outer tube portion 2. The `
device is provided with two caps 3 and 4 of which one rests on the inner wall 5 of the inner tube portion while the other rests on the ~-outer wall 7 of the outer tube portion. Both caps extend beyond the ends of the respective tube portions 6 and 8.
The details of the functtoning of the telescoping shift in a preferred embodiment will be illustrated below when describing FIG. 6. At this place it is noted that in FIG. 2 the cap 3 is pro-vided with an actuatlng member ~ which has slanting sides 16 aga~nst which the plungers 10 and ll rest under the action of springs 17.
The plungers extend through openings 12 and 12' in the cap 3 and openings 13 and 13' in the inner tube portion and come to a stop in the outer tube portion 2.
The device operates as follows. ~hen the actuating member 9 moves by means of the actuating rod 14 in the Y-direction as furhter shown in F~G. 3, the plungers 10 and ll move along the slanting surfaces 16 and are forced inwardly by the spr;ngs 17.
They then release the tubular portions l and 2 from each other. The .
~L0873~6 r 1 tube portion 1 thereupon can be moved both in the X- and in the Y-direction.
The spring 22 which is provided on the actuating rod 14 is compressed when movement ~n the Y-direction is effected. It then pushes the actuat~ng member 9 in the X-direction so that its slanting sides 16 abut against the plungers 10 and 11 ~hich now are pressed against the outer tube portion 2 and after moving through the open-ing 34 are pushed into this tube portion and thus secured in posi-tion. In this manner various lengths of the guide shaft can be ob-tained.
F~G$. 4 and 5 show a slightly d;fferent embodiment in which the actuating member 9 is provided with guide notches lB. A
cap 3 is again provided in the inner tube portion 1 and a cap 4 in the outer tube portion 2. The actuating member 9 is again provided with an actuating rod 14 in the same manner as in the embodiment of FIGS. 2 and 3. However, the plungers 10 and 11 engage the actuating member 9 by cams 19 which move in the guide notches 18. Upon moving the actuating rod i4 into the position as illustrated in FIG. 3 the device of FIG, 5 operates as follows;
If the rod 14 is moved against the action of the spring 22 the notches 18 are caused to move along the plungers 10 and 11 so that the cams 19 are moved closer to each other and the plungers move inwardly. This causes the plungers to be freed of the openings 34 and thus the tube portions 1 and 2 are released for movement. Since the spring 22 in the same manner as in FIG, 2 acts to force the ac-tuating member deeper into the cap 3 the notches 18 and the cams 19 also move and cause the plungers 10 and 11 to be pushed outwards when they are fixed aga~n in their posit~on as soon as they become align-ed with the openings 34.
In this embodiment there is also pro~ided rearwardly of .. ,. , :
1~373~6 1 the cap 3 a U-shaped lockin~ member 26 ~hich ~ th~e ~os~tion whe~e the tubular port~ons 1 and 2 are furthest p~lled apart will enter with its latch 27 through opening 28 in the inner tube portion 1 and further into the rçcesses 2~ provided ~n the outer tube portion.
Thus, a complete pulling apart of the tw~ tube portions cannot take place.
In order to ~ntentionally separate the two tube portions~
completely, it is, however, possible to depress the knob 30 whereby the tube port~ons are released aga~nst each other.
FIG. 6 shows in section the handle 33 where there is provided a release knob 15 which extends into a sleeve 36 of the ac~
tuating rod 14. The knob 15 is arranged slidingly in the outer tube portion and in the handle so that it serves to move the actuating rod back and forth.
FIG. 7 in an enlarged section shows again the function of the caps and the interlocking arrangement of the two tube portions.
The cap 4, which is provided on the outer face 7 of the outer tube portion 2, has a bent-back front portion which envelopes the end por-tion of the outer tube, and with its bent-back flange abuts the in-ner tube 1.
The cap 3 (not shown in this Figurel also extends inthe space between the two tube portions and thus improves the guide action. Since the bent-back ends of the two caps, such as end por- - .
tion 35 of cap 4 are elastic and have a tendency to exert an outward pressure, but on the Qther hand may also be pressed together, there is compensation for any deviations in the two tube diameters.
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims.
