Definitions
- the swiveling and rotatable connecting piece for the intake manifold Tilt and turn joint at the rear end of the floor nozzle mostly behind the floor support.
- the base plate during suction operation regardless of the orientation of the suction pipe and the nozzle housing always plane-parallel is aligned with the floor.
- Floor nozzles of the described Construction enable an effective and smooth-running Sucking and have proven themselves in functional terms.
- the pivoting bracket of the base plate on the upper part of the housing however requires manufacturing and assembly technology complex measures.
- the upper housing part threaded holes on the side, in the shaft journals are screwable.
- For assembly is a precise alignment of both the base plate and The rollers are required while the shaft journal is from the outside inserted into the threaded holes in the upper part of the housing and screwed to the upper part of the housing.
- the assembly is complex.
- too known execution in need of improvement because the production the threaded holes in the upper part of the housing and the manufacture separate shaft journal with threaded connections required additional and relatively complex processing.
- the base plate only on their is supported at both ends and is annoying with wide floor nozzles large bearing distance results.
- the upper housing part and a lower housing part with a permanently attached Floor plate by extending over the entire width of the Floor nozzle extending shaft rotatably connected.
- the upper part of the housing and the lower part of the housing carefully aligned so that bearing holes are aligned and the shaft can be inserted. Then the wave be secured.
- the assembly is complex.
- a floor nozzle known from DE-A-30 09 648 are on the Fork-shaped locking elements on the inside of an upper housing part integrally formed, which engage on a continuous shaft axis and keep them rotating.
- the shaft axis passes through bearing bores a lower housing part supporting the base plate.
- To fix the shaft axis are on the inside formed on the upper part of the housing, which overlaps the end faces of the shaft axis extend. This one too Execution bothers that a separate shaft axis is provided and must be pre-assembled with the lower part of the housing.
- the production of the bearing holes in the lower part of the housing requires machining and increases the manufacturing effort.
- the invention has for its object a floor nozzle Specify the type described above, which is characterized by a simple construction with as few parts as possible distinguished and easy to assemble. In particular, should mechanical processing at the bearings between the upper part of the housing and base plate as well as separate connecting elements omitted.
- journal as well as interacting with the trunnions by latching Bearing journals on the back of the base plate and integrally formed on the inside of the upper housing part are.
- the bearing journals and bearing journals are preferably by injection molding, together with the base plate or the upper housing part and do not require any machining.
- the bottom plate is at least two bearings consisting of trunnions and trunnion seats connected to the upper part of the housing. Preferably are four, distributed over the width of the nozzle housing Storage locations provided.
- the invention teaches that on opposite Side faces of the upper part of the bearing journal are formed, which also form axes for rollers and the ends of which are in journals on the back of the base plate can be snapped into place.
- the bearing journals can be designed as fork-shaped locking elements.
- Another embodiment of the invention consists of the journal receptacles from closed recesses and the trunnion mounts and / or the trunnions are on Arrows arranged one for the purpose of locking the Adequate bearing journals with the associated bearing journal receptacles Bending elasticity.
- bearing journal and trunnion receptacles are integral parts of the base plate and the upper part of the housing are, in the course of the molding process, e.g. as injection molded parts, without machining be produced and without tools by locking are pivotally mountable.
