Definitions

  • the invention relates to a telescoping device for a vacuum cleaner according to the preamble of claim 1.
  • Such telescoping devices are well known in vacuum cleaners and serve to adapt a length of suction tube to allow comfortable suction under different conditions, e.g. at different body sizes of several operators or to expand the suction area to be reached.
  • two tubes of different diameters are telescoped over a sealing ring for telescoping.
  • the location where the sealing ring is seated is problematic due to friction and the dust that may be deposited in this area.
  • Due to the smaller inner diameter of a tube the transition between the two tubes is an additional flow resistance. This flow resistance and leaks in the telescoping cause suction power losses of the vacuum cleaner. This increases the energy consumption of the vacuum cleaner and its energy efficiency is reduced.
  • An object of the invention is correspondingly to provide a telescopic device for a vacuum cleaner, with which the above-mentioned disadvantages can be avoided.
  • a telescopic device for a vacuum cleaner which comprises a base part and a handle part, wherein the telescoping device can be coupled with a suction tube and / or a suction hose, provided that the handle part a telescopic rod, which has no suction, arranged at one end Handle, wherein the telescopic rod is slidably coupled to the base part.
  • the object is also achieved with a vacuum cleaner with a telescoping device as described here and below.
  • the advantage of the invention is that the functions of the telescoping and the air duct have been separated. This results in a low loss of suction power, since the resulting in two telescoped pipes additional flow resistance, which reduces the suction, eliminated.
  • By laying the telescopic function outside of the suction pipe there are no more suction power losses due to leaks in the sealing area or transition, as is the case with two pipes.
  • One Hose connections for a suction hose leading to the vacuum cleaner can be coupled directly to the suction pipe and, due to the separation from the handle, there is no need to compromise on diameter and shape in terms of handling.
  • the combined with the suction tube base part comprises a guide receptacle into which the telescopic rod can be inserted and in which the telescopic rod is displaceable.
  • the guide receptacle which is preferably formed as at least partially closed enclosure, provides a stable support for the telescopic rod and thus a secure guidance of the suction tube via the telescopic rod.
  • the telescoping device advantageously comprises a suction tube as a base part, wherein the telescopic rod is coupled via a coupling device displaceable with an outer side of the suction tube.
  • the coupling device allows a particularly simple coupling between telescopic rod and suction tube.
  • the telescopic rod and the suction tube are coupled such that the telescopic rod extends at least in sections along an upper side of the suction tube.
  • the telescopic rod then extends in an area in which it can be extended without an operator being hindered by the suction hose, because this then runs below the handle.
  • the coupling device is arranged on a lower part of the telescopic rod.
  • the coupling device encloses the suction tube at least partially to ensure a stable connection between the suction tube and telescopic rod.
  • the indentations are therefore preferably arranged in a section in which the telescopic rod can be moved.
  • the length of the portion with the notches approximately correspond to the length of the telescopic rod, so that the full length of the telescopic rod can be exploited.
  • the telescoping engages and can thus be set to a certain length and thereby permanently adapted for a particular purpose.
  • the catch in the notch or notches can be easily solved at any time if required and the telescoping device can be adjusted to a different length using the remaining notches.
  • Comparable or at least similar indentations or locking elements can also be provided in the embodiment of the telescoping device with guide receptacle into which the telescopic rod can be inserted and fulfill the same purpose, namely a stable but flexible locking of the telescoping device at a certain length.
  • the notches are evenly spaced from each other.
  • the adaptation of the length of the telescoping device can take place in uniform steps.
  • the base part comprises a receiving part for the positive reception of the suction tube or the suction hose, a releasable but sufficiently strong connection results between the base part and the suction tube or suction hose, which does not unintentionally release during suction.
  • a receiving part of the Saug orientalszel is minimized.
  • the telescoping device comprises a holding device for the suction hose coupled in an upper region to the telescopic rod.
  • the suction hose can be guided at the level of the handle.
  • the suction hose is therefore not even when fully extended telescopic rod during suction on the ground and therefore does not constitute an obstacle for the operator.
  • the suction hose can be easily removed laterally from this holding device, which is preferably sickle-shaped.
  • the suction hose extends to a transition to the handle along the telescopic rod. This results in a particularly simple guidance of the vacuum cleaner.
  • Fig. 1 schematically shows a simplified telescoping device 10 for a vacuum cleaner (not shown) according to an embodiment of the invention.
  • the telescoping device 10 comprises a base part 12 and a handle part 14, wherein the handle part 14 comprises a telescopic rod 16 without suction function and a handle 18 arranged at the end thereof.
  • the base part 12 comprises a guide receptacle 20 into which the telescopic rod 16 can be inserted.
  • latching elements or latching recesses may be arranged, with which the telescopic rod 16 can be set to certain lengths.
  • the base part 12 comprises a receiving part 22, in which a suction tube 24 is inserted.
  • the suction tube 24 is fixed via a holding element 26 on the base part 12.
  • a hose connection piece 28 is arranged, to which a suction hose 30 is connected, which leads to the vacuum cleaner.
  • a connection piece 32 for an attachment (not shown), for example a floor nozzle.
  • the telescopic rod 16 instead of the previous upper telescopic tube now no longer conducts air through its interior whereby the rubbing surfaces can no longer pollute and there are no flow losses on this component.
  • the telescopic rod 16 essentially serves only to guide the entire unit, the telescoping device 10, and ends in the handle 18.
  • the function of the air guide is achieved by the base member 12, which replaces the previous lower telescopic tube.
  • the base part 12 with its receiving part 22 receives the slightly angled suction or grip tube 24 in a plug connection.
  • the suction hose 30 is approximately at knee level when sucking.
  • the suction tube 24 is secured with a holding element 26 on the base part 12. To use suction accessories, such as a furniture brush, the suction tube 24 must be pulled out parallel to the handle portion 14.
  • a further embodiment of the telescoping device 10 according to the invention is shown.
  • the suction tube 24 acts as a base part 12.
  • the telescopic rod 16 is coupled via a coupling device 34 with an outer side 36 of the suction tube 24 and extends at an upper side 38 of the suction tube 24 so that they do not come into contact with the suction tube 30 during telescoping got to.
  • the suction hose 30 is connected via the hose connecting piece 28 with the base part 12, ie with the suction pipe 24.
  • a header (not shown) can be connected.
  • the handle 18 is as in Fig. 1 arranged at the upper end of the telescopic rod 16.
  • the coupling device 34 is arranged on a lower part of the telescopic rod 16 and surrounds the suction tube 24 on the side facing the plane of the drawing.
  • the Coupling device 34 the suction tube 24 completely enclose.
  • the suction tube 24 has on a bottom 42 notches 44 which are equally spaced from each other. In the FIGS. 2a and 2b these notches 44 are not arranged along the entire bottom 42; However, this is also possible.
  • they are arranged for example on a length of the suction tube 24, which corresponds approximately to the length of the telescopic rod 16, because these can not be further pushed together due to the handle 18.
  • the telescopic rod 16 In the in Fig. 2a shown position, the telescopic rod 16 is (almost) completely extended, that is, the coupling device 34 engages in notches 44, which are arranged in an upper region 46 of the suction tube 24.
  • Fig. 2b shows the in Fig. 2a illustrated telescopic device 10 in an (almost) completely pushed together state in which the coupling device 34 engages in notches 44 in a lower portion 48 of the bottom 42 of the suction tube 24.
  • the handle 18 is now closer to the hose connection piece 28 for the suction hose 30th
  • Fig. 3 is a further embodiment of the telescoping device 10 shown with guide receptacle 20 with the telescopic rod 16 in the extended state.
  • the receiving part 22 is arranged, in which the suction pipe 24 is inserted.
  • the suction hose 30 is thereby inserted or suspended in a holding eye as a holding device 50, which is located in the upper region of the telescopic rod 16, directly below the handle 18.
  • the suction hose 30 is thus guided below and along the telescopic rod 16. This is advantageous when the telescopic rod 16 is extended, since better control of the suction hose 30 by means of the handle 18 is possible.
  • a deflection of the suction hose 30 is no longer directly on the hose connection piece 28, as in Fig. 1 provided, but via the suction hose 30 itself.
  • Fig. 4 shows the telescoping device 10 from Fig. 3 with uncoupled suction tube 24 and suction hose 30.
  • the embodiment shown here has the advantage that the suction tube 24 in combination with the suction hose 30 can be used independently of the telescoping device 10. This is advantageous, for example, when vacuuming ceilings or motor vehicles, since this could hinder the additional weight or size of the telescoping device 10.
  • a considerably longer hose length 50 cm to 70 cm
  • the hose replaces part of the pipe.
  • FIG. 5 an embodiment of the holding device 50 for the suction hose 30 is shown enlarged.
  • a closed ring 52 is provided for coupling to the telescopic rod 16 and a sickle-shaped part is a holding portion 54 for the suction hose 30.
  • the suction hose 30 can thus be easily inserted or hung on one side in the holding portion 54 and removed again.
  • Fig. 6 shows a further embodiment of the telescoping device 10 with guide receptacle 20 and holding device 50.
  • an elongated suction hose 30 is provided, which without connection to a suction tube 24 (FIG. Fig. 1 ), eg, only a short, fixed connector 56, which has a handle 58 for easier handling, in the corresponding receiving part 22 in the lower part of the base part 12 of the telescoping device 10 is inserted.
  • the suction hose 30 is also fixed on the support member 26 on the base part 12, whereby sagging of the suction hose 30 between receiving part 22 and holding device 50 is avoided.
  • the connecting piece 56 may be formed as a rigid part of the suction hose 30, for this purpose, the hose 30 may be formed as a blow-molded hose.
  • This guide of the suction hose 30 to the bottom has the advantage that a greater length of the suction hose 30 is available when it is decoupled from the telescoping device 10, as in Fig. 7 shown. This is again advantageous when sucking eg motor vehicles.
  • Fig. 3 to Fig. 7 shown embodiments offer advantages in handling, since the suction hose 30 is again performed at the height of the handle 18 as in previous vacuum cleaners and thus does not lie on the floor during suction and is an obstacle for the operator.
  • sucking without telescoping device 10 is a significantly longer hose length available and by the molded on the suction pipe 24 or on the connector 56 handle improved handling is achieved.
  • FIG. 8 shown further embodiment has a change in the base part 12, beo no holder for the suction pipe 24 is required.
  • the suction pipe 24 is a positive locking element and a corresponding positive locking receptacle, in particular a groove / spring combination, z.
  • a circumferential or at least partially circumferential groove or spring on the suction pipe 24 which engages in a corresponding spring or groove on the receiving part 22.
  • Fig. 9a shows for clarity the suction tube 24 with the suction hose 30 dissolved in the telescoping device 10 state. Suction tube 24 and suction hose 30 are combined in the region of the suction connection piece 28.
  • a recess or depression in the manner of a groove is formed as a form-fitting receptacle.
  • Fig. 9b in a schematically simplified representation of a section through a portion of the top of suction tube 24 and suction hose 30 in the region of the suction connection piece 28 with the suction connection piece 28.
  • the form-fitting receptacle is visible as a groove 60.
  • the positive connection can (in the sectional view in Fig. 9b not visible) along a larger portion of the outer peripheral surface of the Saugan gleichstutzens 28, for example, over the entire outer peripheral surface, half of the outer peripheral surface, a third of the outer peripheral surface, a quarter of the outer peripheral surface, etc.
  • Suction tube 24 and suction hose 30 are in the telescopic device 10 on the one hand, characterized in that the suction tube 24 is at least partially inserted into the receiving part 22 and on the other hand held by the combination of the suction hose 30 with the holding device 50.
  • receiving part 22 and / or holding device 50 already act receiving part 22 and / or holding device 50 as a means for fixing the combined with the receiving part 22 suction tube 24.
  • the combination of form-fitting and positive-locking element in the region of the Saugan gleichstutzens 28 and on the inside of the support member 26 act as means for fixing, if the telescoping button 62 is pressed.
  • the combined with the receiving part 22 suction tube 24 is fixed so far as it prevents, for example, a displacement of the suction tube 24 along its longitudinal axis in the combined with the telescoping device 10 state.
  • This embodiment is characterized by easier handling of the suction tube 24. Due to the open base part 12 no encompassing in the operation is more necessary. The operator can reach under the base part 12 by hand, detach the suction tube 24 from its position and continue to use it in the same handling step.
  • the suction connection piece 28 can also have a form-locking element and the holding element 26 can have a corresponding positive-fit receptacle.
  • FIG. 10 Yet another embodiment is in Fig. 10 shown.
  • This variant differs from the preceding in the design of the suction tube 24.
  • the suction tube 24 can be removed by the operator by this engages from below into a space between the suction tube 24 and base 12 resulting gap and the suction tube 24 releases from the base part 12.
  • the fixation in the base part 12 is characterized by a partial wrap of the Suction tube 24 through the base part 12 reaches (see. Fig. 10 ).
  • the return of the suction tube 24 after use is done in a corresponding manner.
  • the operator presses the suction tube 24 in the base part 12 and it snaps into its original, combined with the base member 12 position.
  • the holding member 26 of the base member 12 here with its flexible edges or at least one flexible edge, acts as a means for fixing the combined with the receiving part 22 suction tube 24.
  • Advantages of this embodiment result from the elimination of the handle on the suction tube 24 and This results in greater freedom of movement for the operator in confined spaces and indeed with the telescoping device 10 as a whole or the suction tube 24 detached therefrom.
  • the new type of connection between the base part 12 and suction tube 24 is intuitive and comes without means for releasing the combination of suction tube 24 and base part, z. B. in the form of a lock button or the like, from. As a result, the operator only needs one hand to release the suction tube 24.
  • Fig. 12 shows the telescoping device 10 with the base part 12 and without inserted suction pipe 24
  • an electric version of the telescoping device 10 for connection of electrically operable attachments possible.
  • This is very easy and inexpensive to implement, since no power cable must be laid in the telescoping device 10.
