Definitions
- the invention relates to a vacuum cleaner mouthpiece according to the Preamble of the first claim.
- a known vacuum cleaner mouthpiece of this type (DE-GM 88 13 268) has a wheeled wheel Mouthpiece body with one for tillage equipped mouthpiece plate. On this Mouthpiece body is pivotally articulated a suction channel part, through which the sucked in through the mouthpiece plate dirty air to a connecting piece for a Suction pipe or the like. So that on the intake manifold forces not acting on the vacuum cleaner mouthpiece The mouthpiece body, the suction channel part is included Support wheels provided on the over the rear edge protruding portion of the mouthpiece body Suction channel part are rotatably mounted. On the suction duct part are in alignment with each other technological hollow axle sockets, in each one Axle journal of the associated support wheel mounted immediately is.
- the invention is based, with one Vacuum cleaner mouthpiece according to the preamble of the first A simplified claim with simplified means Allow assembly.
- the bearing ring in the axle socket is secured against twisting.
- two Provide latching breakthroughs in the corresponding latches can snap onto the outer surface of the bearing ring.
- the bearing ring is supported with a Ring collar on the free face of the journal, its axial length is such that the locking hook do not hit the bottom of the axle socket bore.
- the snap hooks can be easily joined axially and / or the bearing ring with corresponding chamfers be provided, which the necessary radial adjustment of the Automatically cause snap hooks when assembling.
- a tongue and groove connection serves to secure the bearing ring in the axle socket, the ones at their first when putting them together colliding end flanks also with Centering bevels can be provided.
- Threads and the like Distribute over the entire length of the journal and if necessary in the gap between the free end of the axle socket and penetrate the support wheel base carrying the axle journal the outer jacket of the axle socket is all-round Protective disc, the diameter of which with little play Inner diameter of the impeller is adjusted.
- This Protective disk sits axially from the bottom of the axle socket Center offset within the support wheel, so that a Catch chamber for hair, threads and the like. Is formed from the this contamination without disassembling the jockey wheel from outside can be removed.
- To support this Protective screen and for stiffening the axle socket as well supporting ribs can still be used to form dust-collecting chambers be molded, towards the free end of the axle socket run and in one piece with the axle socket as with the Protective screen are connected.
- Preferably there are four Supporting ribs provided in rectangular planes are arranged so that there is easy demolding in an injection mold. There are two of them Support ribs in parallel planes, which in turn are parallel to the connecting line from diametrically opposite Breakthroughs are in the axle socket.
- the support ribs are in place additionally offset in addition to the latching openings Engage the locking lugs of the bearing ring.
- the one Breakout opening and the adjacent support rib The core part can thus be made in one piece with the rest of
- the invention is based on the sketches of a Embodiment explained in more detail.
- a vacuum cleaner mouthpiece consists of a mouthpiece body 1, the one on its bottom surface during operation at least one suction channel, a sealing lip, Support elements or the like.
- Mouthpiece plate 2 has and with a pivotally attached to it protruding the rear edge 3 of the mouthpiece body
- Suction channel part 4 is equipped with a lateral distance next to the rear edge with rotatable support wheels 5 is provided.
- On the suction duct part 4 there is also a swiveling suction nozzle 6 for connection to a Suction tube or a handle of one with a vacuum cleaner connected suction hose.
- the support wheels 5 take via the connecting piece 6 on the suction nozzle acting forces so that the mouthpiece plate 2 thereof can be carried unloaded over the floor to be vacuumed.
- the support wheel 5 in simple mountable secured against axial displacement in Axle socket 7 can be rotated between the Achszapfan 9 and the Achsstutzen 7 concentrically against both parts 7.9 axially against displacement secured bearing ring 10 arranged.
- the Bearing ring 10 is secured against rotation in the axle socket 7.
- the bearing ring 10 preferably two diametrically oppositely arranged locking lugs 11, which according to 2 in the assembled position in adapted Snap-through openings 12 in the jacket of the axle stub 7 snap in.
- the bearing ring 10 is supported with a Annular collar 13 on the free end face 14 of the axle stub 7 from when the locking lugs 11 are not used for reliable securing against axial displacement are sufficient.
- the respective Axle pin 9 is at least axially from its free end slotted over a partial length and thus forms in a radial Sheath segments 15 which can be bent out in a spring-elastic manner of adjacent jacket segments 16 through a slot 17 are separated. At least one, but preferably three the jacket segments 15 are at their free ends Locking hook 18 provided the adjacent free end face 19 radially overlap the bearing ring 10 and thus prevent that the journal 9 after assembly from the bearing bush 10 can be pulled out unintentionally.
- axle socket 7 preferably four axially on its outer surface to provide directed support ribs 25 to the free end 14 sloping down and in parallel, at right angles mutually parallel levels that are parallel to Axis direction of the axle stub 7.
- Two of these Support ribs are parallel to the connecting line of the Lockouts 12 and sit next to the same, so that all four support ribs and the locking openings in one Injection mold can be formed that only in the bearing axis of the support wheels 5 receiving plane is divided and only for the formation of the cavities in the Axle socket 7 separately pullable core parts required.
- This Support ribs 25 also stiffen a protective disk 26, which also on the outer surface of the axle stub 7th is integrally formed.
- This protective disk 26 sits on middle section of the axle stub 7 offset at a distance from the wall section 27 of the axle socket 7 Suction channel part 4 so that a catch chamber 28 is formed in which the respective support wheel 5 from the outside penetrating fibers, hair or similar dirt particles deposit without further into the cavity of the concerned Impeller 5 can penetrate.
- the protective disk 26 is therefore in diameter so to the inside diameter of the Adjusted support wheel 5, the only one as small as possible radial play between the two parts remains. In the Dirt collecting chamber 28 deposited dirt particles can then manually from the open race end 29 below A simple tool can be removed.
