Definitions

the invention relates to an arrangement for releasably connecting a suction nozzle to the suction opening of a vacuum cleaner according to the preamble of claim 1.
the invention is therefore based on the object of developing a generic type in such a way that both the possible longitudinal tolerances of the parts to be sealed against one another and the tensile forces exerted on the sealing of the coupled parts are unaffected.
the problem is solved by the features specified in the characterizing part of claim 1.
the sealing element connected to the free end of the tubular extension of the locking element protrudes in the axial direction into the annular gap existing between the tubular end of the suction nozzle and the suction opening of the vacuum cleaner. Since the sealing element does not rest at any point in the axial direction, the sealing effect of the sealing element is in no way influenced in the event of an axial movement of the suction nozzle or in the event of axial length tolerances thereof.
the sealing element is only on the wall in the axial direction moved along the suction opening without being affected by its sealing effect.
An elastic sealing lip is expediently formed as a sealing element on the free end of the extension. This makes a separate installation of the sealing element unnecessary.
a good sealing effect is achieved in that an obliquely outwardly pointing collar is formed as a sealing lip on the tubular part of the extension.
the extension provided on the locking element can also be used for locking the locking element, in that a latching element which can be locked on the tubular end of the one pipe socket is provided on the inside of the tubular extension.
suction opening of the vacuum cleaner is provided on the wall part 1.
a suction nozzle 3 connected to a suction hose can be coupled to this suction opening 2.
the suction opening 2 thus forms another pipe socket which can be coupled to the suction socket 3.
One suction nozzle 3 has a tubular end 4 which can be inserted into the suction opening 2 and which has a radial distance from a tube extension 5 of the suction nozzle 3 to a certain axial length is surrounded. In this way, an annular space 6 results between the tubular end 4 and the tube extension 5.
a locking element 7 is inserted in the annular space 6.
the locking element 7 has a ring part 8 which is concentric with the tubular end 4.
On the ring part 8 two radially outwardly projecting locking cams 9 are formed, each of which protrude through a slot 10 of the tubular extension 5 and engage under a locking projection 11 formed on the wall part 1.
the suction nozzle 3 is held on the vacuum cleaner housing in the suction opening 2.
an unlocking button 13 projecting outward through a corresponding opening 12 in the wall of the suction nozzle 3 is provided on the ring part 8.
a corresponding pressure is exerted on the unlocking buttons 13.
the ring part 8 is correspondingly deformed radially inward, so that the locking lugs 9 disengage from the locking projection 11 and the suction nozzle 3 can be pulled out of the suction opening 2.
a tubular extension 14 is also provided on the locking element 7.
the inner diameter of this extension 14 corresponds to the outer diameter of the tubular end 4 of the suction nozzle 3, so that the locking element 7 with its extension 14 can be pushed onto the tubular end 4 of the suction nozzle 3.
On the inner wall of the extension 14 locking lugs 15 are provided which engage in correspondingly adapted locking recesses 16 of the tubular end 4.
the locking lugs 15 and the locking recesses 16 are shaped so that in the pushing-on direction of the locking element 7 there is a locking which can no longer be released in the opposite direction to the pushing-on direction.
the push-on distance of the locking element 7 is limited by the unlocking buttons 13 protruding through the opening 12 in such a way that the locking lugs 15 remain in contact with the locking edge 17 of the locking recess 16.
a collar 18 is formed obliquely to the radially outward as a sealing element, which in turn is provided at its free end with a sealing lip 19.
the outside diameter of the sealing lip 19 is dimensioned slightly larger than the inside diameter of the suction opening 2 in the area in which the sealing lip 19 is in the state of the suction port 3 coupled to the suction opening 2 when the suction port 3 is not inserted into the suction port 2. This ensures that the sealing lip 19 bears against the wall 20 of the suction opening 2 when the suction nozzle 3 is coupled to the suction opening 2 under a certain state of tension. This ensures a perfect seal between the coupling point of the suction nozzle 3 and the suction opening 2.
the quality of the sealing point no longer depends on any length tolerances of the parts that are joined together. Also, tensile forces exerted on the suction nozzle 3 no longer have any influence on the sealing effect. Such influences can only lead to an axial displacement of the line of contact of the sealing lip 19 with the wall 20 of the suction opening 2.
