Definitions

  • the present invention relates to a vacuum cleaner suction pipe according to the preamble of claim 1.
  • Vacuum cleaner suction pipes are known in the prior art in a variety of configurations. Telescopic vacuum cleaner suction pipes have the advantage that they can be adjusted to the body size of an operator or to different application situations during use for short or long distances by changing the length, on the one hand to enable ergonomic operation and on the other hand to allow a multifunctional use of the vacuum cleaner for various suction tasks to guarantee.
  • Such vacuum cleaner suction tubes usually comprise a plurality of tube segments which are arranged one behind the other and inserted into one another so that they can be telescoped relative to one another by axial displacement of the tube segments.
  • the tube segments are manually shifted by the operator, ie pushed axially into or onto one another.
  • Various locking mechanisms are known for locking a certain position of the pipe segments, which reliably prevent an unwanted relative movement of the pipe segments during use of the vacuum cleaner suction pipe.
  • Recesses are often used in the walls of the pipe segments, which interact with corresponding locking elements on the other pipe segments.
  • Such vacuum cleaner suction pipes are disclosed in DE 195 28 814 C1 , DE 87 07 887 U1 and DE 195 24 290 C1 .
  • vacuum cleaner suction pipes are often made of stainless steel, with attachment elements, for example made of plastic, being attached at least in the two end regions of a vacuum cleaner suction pipe.
  • the add-on elements are advantageously pushed onto the vacuum cleaner suction pipe or pushed into the vacuum cleaner suction pipe. A particular requirement is the leak-free seal between the vacuum cleaner suction pipe and the add-on element.
  • the vacuum cleaner suction pipes known from the prior art have often has the disadvantage that a reliable seal, especially when using certain plastics for the add-on elements, cannot be sufficiently ensured between the vacuum cleaner suction pipe and the add-on element.
  • the invention is therefore based on the object of specifying a vacuum cleaner suction pipe which enables a reliable and leak-free connection to an attachment element when using any type of plastic for the attachment element.
  • one embodiment of the vacuum cleaner suction tube provides that an outward radial movement of the actuating mechanism relative to the outer tube is blocked by the outer tube. Conversely, an outward radial movement of the actuating mechanism relative to the outer tube is blocked by the actuating mechanism or by the base plate.
  • the base plate is dimensioned such that the actuating mechanism passes outward through the recess of the outer tube, but the base plate remains in the interior of the outer tube and strikes the wall of the outer tube. A pushing or pulling the actuating mechanism outward in the radial direction out of the outer tube is therefore not possible.
  • the actuating mechanism can lock the end sleeve in position in various ways.
  • the end sleeve recess has approximately the same size as the dimensions of the base plate, so that the base plate is form-fitting engages in the end sleeve recess.
  • the end sleeve can be inserted into the outer tube during manufacture of the vacuum cleaner suction tube, the actuating mechanism already being located in the outer tube.
  • the end sleeve is inserted into the outer tube until the corresponding elements, that is to say the base plate of the actuating mechanism and the end sleeve recess, are in engagement with one another.
  • the sleeve receives a movement impulse in this position, the contours of the end sleeve recess hit the base plate and movement is prevented.
  • the stronger the material of the end sleeve the deeper the end sleeve recess can be. Consequently, the area with which the end sleeve is supported via the end sleeve recess on the base plate of the actuating mechanism is also increased, insofar as the material thickness of the base plate, that is to say the height of the base plate, corresponds to the material thickness of the end sleeve.
  • the end sleeve recess need not necessarily describe a complete recess.
  • One possible configuration is, for example, a recess in which the base plate can engage, recesses being able to be formed in the recess, so that only the elements of the latching device pass through the end sleeve recess, which contribute to locking the vacuum cleaner suction pipe.
  • the actuating mechanism is connected to the end sleeve in a frictional manner, so that an axial movement of the end sleeve relative to the outer pipe is blocked.
  • the end sleeve is only inserted into the outer tube, the actuating mechanism or the base plate of the actuating mechanism exerting a sufficiently large friction on the end sleeve so that the end sleeve can no longer be easily removed from the outer tube.
  • the size and design of the end sleeve recess is irrelevant, as long as it ensures that the locking device in the locking position can pass through the end sleeve recess in the direction of the inner tube, so that the locking device is in engagement in the locking position with at least one locking recess on the inner tube and a movement of the outer tube and inner tube is blocked relative to each other.
  • An advantageous embodiment provides that elongated webs are formed on the end sleeve, which serve as spacers from the outer tube to the end sleeve, the end sleeve then being connected to the outer tube only via the webs.
  • the material thickness of the base plate or the actuation mechanism can be selected independently of the end sleeve. In the case of a relatively thick base plate, insertion of the end sleeve may not be possible without damage.
  • the design of the elongated webs can be selected such that the base plate is arranged at a distance of two webs, can be selected such that the end sleeve can still be inserted into the outer tube, but the friction between the end sleeve and the base plate is so great that removal of the end sleeve is not easily possible.
  • the arrangement and number of bars can be chosen more or less freely.
  • a further embodiment of the vacuum cleaner suction pipe provides that the end sleeve has an insertion end and an outer end and that the insertion end tapers in at least one area.
  • the area in which the introducer tapers should be approximately as large as the width of the base plate.
  • the end sleeve can thus be inserted more easily into the outer tube, since the tapered area means that the friction between the base plate and the end sleeve is not too great.
  • the sleeve can thus be inserted into the outer tube without problems until it reaches its desired position, for example until the end sleeve recess and base plate engage.
  • a further advantageous embodiment of the vacuum cleaner suction tube provides that at least one stop is provided at the outer end.
  • the stop can only cover a small area or several small areas of the outer end.
  • the stop is formed by increasing the outer diameter of the end sleeve.
  • the stop is consequently formed all around.
  • the stop can also be designed, for example, in such a way that the material is bent in the region of the enlarged outer diameter by a channel directed towards the insertion.
  • the end sleeve thus not only abuts the end of the outer tube, but encloses the end of the outer tube. Since the outer tube is usually made of stainless steel or another metal, the ends of the outer tube can be sharp.
  • the channel shape of the stop encases the sharp edge so that the risk of injury is minimized.
  • the material in the area of the enlarged outer diameter does not have to be the same material from which the rest of the end sleeve is made.
  • a foam or rubber mixture can also increase the tightness at the end of the pipe and accordingly also further reduce the risk of injury, since the material is softer than conventional plastics.
  • the outer pipe has exactly one outer pipe recess.
  • One of the advantages of the vacuum cleaner suction pipe according to the invention is that the end sleeve is not fastened separately to the outer pipe, but is held in the outer pipe by the interaction of the individual components.
  • the vacuum cleaner suction pipe according to the invention only one recess is necessary as long as no further components have to be attached to the outer pipe. With only one recess, on the one hand, the locking device can interact with the inner tube and, on the other hand, the components can be securely connected to one another.
  • the inner pipe comprises at least one longitudinal groove and that at least one spring corresponding to the longitudinal groove is formed on the end sleeve, so that the inner tube is guided by the end sleeve in the outer tube.
  • the inner pipe comprises at least one longitudinal groove and that at least one spring corresponding to the longitudinal groove is formed on the end sleeve, so that the inner tube is guided by the end sleeve in the outer tube.
  • the groove can also be formed in the interior of the end sleeve, a corresponding spring being provided on the inner tube.
  • the inner tube comprises at least one longitudinal groove and that at least one spring corresponding to the longitudinal groove is formed on the outer tube, so that the inner tube is guided in the outer tube.
  • the longitudinal groove can be formed, for example, in the interior of the outer tube, the corresponding tongue being formed on the inner tube.
  • the groove on the outer tube could be realized, for example, by a deformation of the tube or by two folds in the outer tube, so that a V-shaped groove is created in the outer tube.
  • a method for producing a vacuum cleaner suction pipe with at least one inner pipe, with at least one outer pipe, with at least one actuating mechanism and with at least one end sleeve, also fits to the described vacuum cleaner suction pipes, the end sleeve having at least one end sleeve recess, the outer pipe having at least one Has outer tube recess, wherein the inner tube has a plurality of locking recesses and wherein the actuating mechanism has a base plate having at least one locking recess.
  • the actuating mechanism is guided from the inside of the outer tube through the outer tube recess, that the end sleeve is inserted into the outer tube and is blocked in axial movement by the actuating mechanism and that the inner tube is inserted into the end sleeve and the actuating mechanism is blocked in the radial movement by the inner tube.
  • a logical sequence for assembling the vacuum cleaner suction pipe is subdivided into the following steps: inserting the actuating mechanism into the outer pipe, inserting the end sleeve into the outer pipe and locking the end sleeve through the actuation mechanism and ultimately inserting the inner tube.
  • Fig. 1 shows a schematic representation of an embodiment of a vacuum cleaner suction pipe 1.
  • the vacuum cleaner suction pipe 1 has an inner pipe 2, an outer pipe 3, an actuating mechanism 4 and an end sleeve 5.
  • An end sleeve recess 6 is formed in the end sleeve 5 and an outer tube recess 7 is formed in the outer tube 3.
  • the inner tube 2 has locking recesses 8, which serve that the actuating mechanism 4 can engage in the locking recesses 8 by means of a locking device in order to block the relative displaceability of the inner tube 2 and the outer tube 3 relative to one another.
  • the actuating mechanism 4 has two latching recesses 9 (in Fig.
  • the individual components work together in such a way that they fix each other.
  • the base plate 10 of the actuation mechanism is dimensioned such that it is larger than the outer tube recess 7. In this way, the actuation mechanism 4 cannot be pushed out of the inside of the outer tube 3 through the outer tube recess 7.
  • the end sleeve recess 6 of the end sleeve 5 in turn interacts with the base plate 10 of the actuation mechanism 4, so that an axial displacement of the end sleeve 5 is blocked by the actuation mechanism 4.
  • the inner tube 2 prevents the actuating mechanism 4 from being pushed into the outer tube 3 in the radial direction. All components are therefore mutually mutually exclusive.
  • Fig. 2 shows the base body 14 of the actuating mechanism 4. It comprises the base plate 10 and a holder 15 for the latching device of the actuating mechanism 4.
  • the base plate 10 In the base plate 10, two latching recesses 9 are formed, through which the latching device, not shown here, can pass in order to engage with the latching recesses 8 of the Inner tube 2 to engage.
  • the base plate is adapted to the pipe contour, so that the base plate has a curvature 16.
  • Fig. 3 shows an embodiment of an end sleeve 5.
  • webs 18 are formed, which serve to stabilize the end sleeve 5.
  • they reduce the contact surface of the inserted inner tube 2 in the end sleeve 5, which additionally reduces the friction.
  • the inner tube 2 can thereby be moved more easily within the end sleeve 5.
  • the movement in the outer tube 3 is correspondingly smoother since the inner diameter of the end sleeve 5 is smaller than the inner diameter of the outer tube 3.
  • a spring 19 is formed on the inside 17 of the end sleeve 5, which corresponds to a groove formed on the inner tube 2.
  • the spring 19 is arranged opposite the end sleeve recess 6.
  • the end sleeve recess 6 is merely a recess in the material of the end sleeve 5.
  • two smaller recesses 20 are formed in the end sleeve recess.
  • the two recesses 20 correspond to the two latching recesses 9 in the base plate 10.
  • a conically tapering region 21 is formed on the inlet 11, which begins at the end sleeve recess 6 and ends at the end of the end sleeve 5 at the inlet 11.
  • the conical region 21 serves to simplify the insertion of the end sleeve 5 into the outer tube 3 if the actuating mechanism 4 is already arranged in the outer tube 3.
  • the actuating mechanism 4 can slide on the conical region 21 during insertion and does not block the end sleeve 5 during the insertion.
  • the stop 13 is turned towards the introducer 11. In this way, the stop 13 encloses the end of the outer tube 3, not shown here, when the end sleeve 5 is fully inserted into the outer tube 3.
  • Fig. 4 shows the base body 14 of the actuating mechanism according to Fig. 2 in the end sleeve recess 6 of the end sleeve 5 according to Fig. 3 is inserted.
  • the end sleeve recess 6 is designed to fit the base plate 10.
  • the base body 14 has hardly any room for movement in the end sleeve recess 6.
  • the end sleeve 5 has no room for movement in the outer tube 3, not shown here, if the actuating mechanism 4 is already arranged in the outer tube 3.
  • Fig. 5 shows a sectional view of a vacuum cleaner suction tube 1, in which all components, ie inner tube 2, outer tube 3, actuating mechanism 4 and end sleeve 5 are connected to one another.
  • the outer diameter of the region of the inner tube 2, which is not intended to be immersed in the outer tube 3 is enlarged. In this way, a simple stop 22 is realized.
  • both the outer and the inner diameter of the outer tube 3 are enlarged in a section 23.
  • the end sleeve 5 is arranged in this section 23.
  • the inner and outer diameters are somewhat smaller than in section 23, so that there is no excessive distance between inner tube 2 and outer tube 3, which could lead to unfavorable flow properties during the suction process.
  • FIG. 6a a schematic representation of a method for producing a vacuum cleaner suction tube 1.
  • the actuating mechanism 4 is inserted into the outer tube 3 and passed through the outer tube recess 7. Due to the larger base plate 10, the actuating mechanism 4 cannot be pushed out of the inner tube 3 from the inside.
  • Fig. 6b the end sleeve 5 is inserted into the outer tube 3, the actuating mechanism 4 being already arranged in the outer tube.
  • the end sleeve 5 must be guided past the base plate 10 of the actuating mechanism 4 during insertion.
  • the only possibility of the end sleeve 5 to be guided past the base plate 10 is a slight elastic deformation, which in Fig. 6b is strongly exaggerated.
  • the end sleeve 5 is inserted into the outer tube 3 until the base plate 10 engages in the end sleeve recess 6.
  • Fig. 6c shows how the end sleeve 5 is already arranged completely in the outer tube 3.
