Definitions

  • the present invention relates to a suction conduit device connectable to a floor vacuum cleaner or a central suction system, comprising a flexible, axially stretchable suction hose, being connectable to a suction opening in said floor vacuum cleaner or said central suction system, and a rigid tube handle, possibly consisting of several tube sections, for connection between the suction hose and a suction nozzle, wherein the suction hose and the tube handle are dimensioned to at least partly slide telescopically into each other.
  • suction conduit devices are previously known, e.g. from US-A-2,867,833 (Duff) and EP-A-37674 (Dyson).
  • the vacuum cleaner is a combination apparatus, which can be converted between a position for floor vacuum cleaning without a hose, wherein the elongated apparatus casing is upright and via a lower suction opening sucks dirt directly into a filter bag inside the apparatus, particularly by means of a rotating brush, and a position for manual vacuum cleaning above the floor, wherein a suction hose stored in the apparatus casing is connected to the filter bag and pulled out from its storage position for conventional vacuum cleaning by means of a suction nozzle easy to handle.
  • suction hoses are used which in the storage position are relatively short and which can be resiliently extended temporarily to a length being up to four times longer than in its state of rest (storage position).
  • the suction hose and a straight, rigid tube section, which is inserted into the suction hose, are stored in a tubular storage space in the apparatus casing, whereas another, likewise rigid tube section connected to the straight tube section at its upper end, serves as a handle during floor vacuum cleaning.
  • the rigid tube sections and the suction hose are lifted out of the storage space, whereupon one end portion of the suction hose is connected to an upper suction opening in the apparatus, while its second end portion is connected to the bent tube section, which in turn can be connected to the straight tube section should a longer tube handle be desired.
  • the hose is kept resiliently extended to a desired length, which may correspond to three or four times the length in the state of rest (storage position).
  • the hose is removed from the upper suction opening, and the tube sections are separated from the hose and are turned around. Thereafter, the straight tube section is pushed through the hose and is inserted into the storage space of the apparatus and is secured in storage position by bayonet locking.
  • the bent tube section projects freely from the hose and serves as a manouvering handle.
  • one end portion of the suction hose is permanently connected to the apparatus casing, which for this purpose is provided with a connection sleeve fixedly mounted at a suction opening.
  • a rigid tube provided with a handle is telescopically insertable through the second end portion of the suction hose and can be inserted into a storage position, wherein the tube is secured in the connection sleeve of the apparatus casing and the handle can be used for manoeuvering of the apparatus during floor vacuum cleaning.
  • Automatically operating valve devices ensure that a suction opening located at the bottom part of the apparatus is connected to the filter bag.
  • the tube When converting the apparatus for manual vacuum cleaning, the tube is pulled out of the connection sleeve and the suction hose, and an abutment at the end portion of the tube ensures that this end portion is not separated from the suction hose but engages with an end sleeve member of the suction hose. Thereafter, vacuum cleaning can be performed in a usual manner. Even in this case the suction hose is very short in its state of rests (storage position) and must be resiliently extended in order to reach a desired range relative to the apparatus casing. Separate storage of the suction conduit device is not possible in this apparatus.
  • the suction conduit device suction hose and tube handle
  • the rigid tube handle is partly inserted into the suction hose and mechanically coupled to the apparatus casing, so that its upper portion can serve as a manouvering handle during floor vacuum cleaning (wherein the suction hose is not used).
  • the object of the present invention is to achieve a suction conduit device being separable in its entirety from a floor vacuum cleaner or a central suction system and which can be stored as a compact unit separately from the floor vacuum cleaner or the central suction system.
  • Another object is to use a suction hose having a greater length in its operative position, without being resiliently extended in the longitudinal direction, than in the known apparatuses, so that the suction hose does not exert any pulling force on the floor vacuum cleaner or on the suction opening connection of the central suction system during vacuum cleaning.
  • the suction conduit device should be easy to handle and should be easily convertable between an operative position and a compact storage position.
  • the suction hose is axially contractable from an operative position to a contracted storage position inside or on the tube handle.
  • the suction hose In the operative position, the suction hose is essentially free from tension and, thus, exerts no force on the floor vacuum cleaner (except when the latter is to be moved) or the suction opening connection of the central suction system.
  • the suction hose In the operative position, the suction hose is essentially free from tension and, thus, exerts no force on the floor vacuum cleaner (except when the latter is to be moved) or the suction opening connection of the central suction system.
  • normal manual vacuum cleaning is facilitated as the tube handle and the nozzle mounted thereon can be manoeuvered without being affected by a disturbing force from the suction hose.
  • suction hose is telescopically insertable or mountable relative to the tube handle and can thus be stored together with the same as a compact unit upon mounting or insertion (aft.er the suction hose has been separated from the floor vacuum cleaner or the suction opening connection of the central suction system).
  • the mutually co-operating holding means of the suction hose and the tube handle which keep the suction hose in its contracted storage position inside or on the tube handle, can easily be designed so as to facilitate the conversion between the operative and storage positions, as will be described below.
  • suction conduit device has the following advantages:
  • the suction conduit device can be packed in space-saving, thin packages
  • the suction hose is stable also in its operative position and at varying internal pressure, as it can be made more robust than previously known, axially flexible hoses (which are extended 3 to 4 times longitudinally).
  • Fig. 1 shows a floor vacuum cleaner and a suction conduit device according to the invention in its storage position, the corresponding operative position being indicated by dashed lines;
  • Fig. 2 shows the suction conduit device in its operative position, wherein the suction hose is connected to a floor vacuum cleaner;
  • Fig. 3 shows in a side view and partly in section the connection of the suction hose to the tube handle in its operative position
  • Fig. 4 shows a corresponding view of the coupling sleeve of the suction hose, which in its storage position cooperates with one end portion of the tube handle;
  • Fig. 5 shows in a side view and partly in section an alternative embodiment of the suction conduit device according to the invention.
  • FIG. 1 a first embodiment of the suction conduit device according to the invention is shown, namely with a suction hose 1, which is externally mountable on a rigid tube handle 2.
  • a suction hose 1 which is externally mountable on a rigid tube handle 2.
  • Fig. 1 the device is shown in its storage position, separated from an upright floor vacuum cleaner.
  • the dashed lines indicate that the flexible suction hose 1 can be connected either to such an ordinary floor vacuum cleaner 3 or to a suction opening or floor valve 3' belonging to a central suction system (not shown).
  • Fig. 2 the suction conduit device 1,2 is shown in its operative position, wherein a coupling sleeve 4 at one end portion la of the suction hose 1 is connected to the suction opening of the vacuum cleaner 3, whereas the other end portion of the suction hose 1 is connected to the rigid tube handle 2 by means of a sleeve device 5.
  • the tube handle consists of a bent tube section 2a and a straight tube section 2b being removably connectable thereto, on the free end of which tube section 2b an ordinary suction nozzle 6 is mounted.
  • the flexible suction hose 1, being in its state of rest without axial tension is 20-80%, in particular 30-40%, longer than the rigid tube handle 2, which per se is common in conventional vacuum cleaners with associated suction conduit devices.
  • the suction hose 1 is axially contractable to the storage position shown in Fig. 1, where it is entirely mounted externally onto the rigid tube handle 2 and is kept in this position by means of holding means, namely the sleeve device 5, which in this position abuts axially against an external stop sleeve 7 on the end portion of the straight tube section 2b, and the coupling sleeve 4, which is internally clamped onto a stop sleeve 8 on the end portion of the bent tube section 2a (Fig. 4).
  • the unit consisting of the tube handle 2 and the mounted suction hose 1 is about 1.2 m long.
  • the sleeve device 5 which is shown in detail in Fig. 3 (in its operative position according to Fig. 2), consists partly of a sleeve-like connection portion 5a, partly of a handle portion 5b.
  • the connection portion 5a is securely connected to the end portion lb of the suction hose 2 shown to the left in the figures and is rotatably connected to the handle portion 5b, which on the outside is shaped as a handle and on the inside has a conical surface 5c, which in the operative position according to Figures 2 and 3 engages with a corresponding conical surface 8a of the stop sleeve 8.
  • the conical angle in this portion of the stop sleeve 8 is such that the stop sleeve extends externally in the direction towards the free end portion of the bent tube section 2a, thereby preventing the sleeve device 5 from sliding off this end portion from the stop sleeve 8.
  • the sleeve device 5 is kept in a fixed position by means of a latch device consisting of a latch pin 9 engaging in a round groove 8b in the conical surface 8a of the stop sleeve 8, and an actuating lever 10, by means of which the latch pin 9 can be freed from the groove 8b, so that the sleeve device 5 can be displaced along the tube handle 2a, 2b to the other end position according to Fig. 1.
  • the handle portion 5b of the sleeve device 5 is used at first.
  • the coupling sleeve 4 consists partly of a connection portion 4a fastened to the hose end la, partly of a coupling portion 4b rotatably connected thereto, which coupling portion 4b is connectable by bayonet locking to the floor vacuum cleaner 3 or suction opening 3' shown in Fig. 1.
  • connection portion 4a is retained by means of mutual clamping action between an internal conical part 4c in the same and an external conical part 8c of the stop sleeve 8.
  • the conical angle is somewhat larger in the part 8c than in the part 4c so that the connection portion is somewhat resilient in a radial direction when fixed into the position according to Fig. 4.
  • the sleeve device 5 could alternatively be secured by clamping on the stop sleeve 8 in the position according to Fig. 3, and the coupling sleeve 4 could be locked by of a latch means in the position according to Fig. 4.
  • Fig. 1 an alternative embodiment is shown wherein the flexible suction hose 1' is insertable under axial contraction inside the section of the rigid tube handle 2'a, 2'b.

  • the coupling sleeve 4' of the suction hose can be secured by clamping, namely when the suction hose 1' is located in the shown storage position according to Fig. 5.
  • the sleeves 4 and 5 of the suction hose can be formed in different ways for adaption to the particular requirements with regard to internal as well as external storage of the suction hose.
  • the locking of the sleeves at the end portions of the tube handle can be modified.
  • the suction hose being longer in its state of rest, can be contracted on or in the shorter tube handle in the storage position as a compact unit separate from the vacuum cleaner itself or from the suction opening of a central suction system.
  • the tube handle can be designed in several ways and possibly also be telescopically conductable, the tube handle being stored in an extended position.
  • the suction hose will automatically expand' axially upon release of the holding means (4,8 and 4',13, respectively) and thus facilitate the telescopical extension to an operative position.
  • a resilient reel could be arranged on the end portion located closest to the suction nozzle (6) or in the sleeve device (5 and 5', respectively) of the hose so that the sleeve device after release of the holding means (5,8 and 5', 12, respectively), is automatically displaced along the tube handle by means of a line being kept stretched between the reel and the sleeve device or said end portion, respectively.
