Definitions
- the invention relates to a suction mouthpiece according to the preamble of the first claim.
- a suction mouthpiece of this type (DE-GM 73 41 134) are in a base plate facing the surface to be extracted Auxiliary elements provided, at least one Suction channel directly into the base plate made of sheet metal is imprinted, while other aids, such as Wheels attached in another holding plate are.
- This holding plate lies on the one to be extracted Surface facing away from the rear side of the base plate and is provided with wheel arches, on the edges of which the respective Wheels with a wheel axle supported on both ends are.
- the disadvantage of this structure is the necessity the manufacture and assembly of the base plate with the Retaining plate.
- the invention is based, with a suction nozzle measures according to the preamble of the first claim to meet through the ease of manufacture and high functionality an uncomplicated assembly and disassembly of auxiliary elements is made possible.
- a suction mouthpiece In a configuration of a suction mouthpiece according to the Invention is the bottom plate with the for Auxiliary elements required brackets in one piece abrasion-resistant and impact-resistant plastic as one component manufactured. Then on this base plate Tools attached in simple plug-in assembly and for example with the help of a flat screwdriver be expanded or replaced by laypeople.
- This can the wheel arch molded into the base plate one of the Have level outgoing flank that under a acute angle to the plane of the base plate is inclined so that they are below the area of the wheel arch scenario at an acute angle to the level of the base plate, i.e. from the wheel axis tilts away.
- the bearing slot in a vertical Projection in the area of the relevant latch rear opposite side of the base plate is open.
- the Bearing slots can therefore be easily driven over Tools are injected, with a core part of the aspirated surface facing side up to the to be formed locking nose can be performed. Need it so none adjustable transversely to the main demolding direction Core slides are used.
- the bottom plate can moreover in the area of the slot guides spherical, protruding beyond the level of the base plate Formations that are just below that of the wheels formed level and end like the skids wheel in question, especially against side impacts shield and an excessive sinking of the base plate in prevent a carpet.
- the spherical shapes are in particular in the main sliding direction of the Suction mouthpiece assigned to rear wheels. in the Roles lying in the front area can be in the Suction channel to be included. In this case it is useful when parallel to the longitudinal direction of the base plate or the suction channel directed wheel axles, in pairs at a distance from each other in the main sliding direction are arranged offset, the lifting flanks each the side of the to provide respective wheel arch.
- the wheels can do this close to the relevant longitudinal side edges of the base plate be used without the possibility to pry out affect.
- the on the elastic foot molded lip protrudes at least down to the level through the free Side edges of the suction channel is predetermined.
- the sealing lip prevents air from being sucked in during operation Slide direction rear side of the mouthpieces.
- the last can be due to its sufficient elasticity between the retaining webs be pushed into the groove, while in the Disassembly with a screwdriver or the like Last foot end between the adjacent retaining webs can be levered outwards. By train on at this end, the rest of the groin triggers the groove in question.
- the invention is based on the sketches of a Embodiment explained in more detail.
- a suction mouthpiece for a vacuum cleaner has one Base plate 1, on which auxiliary elements as a Suction channel 2 with associated thread lifters 3, sealing strips 4, Wheels 5 and support surfaces 6 or support bales 7 are provided are.
- the wheels 5 are partially immersed in Wheel housings 8 in which the wheels with their wheel axles 9 are supported and fixed at both ends.
- the bottom plate 1 is made of plastic in a spray or Press tool manufactured, the suction channel 2, the Wheel arches 8 and brackets 10 for sealing strips 4 or Slots 11 are integrally formed for the wheel axles.
- the bearing slots 11 run perpendicular to the one shown Bottom of the base plate 1 in the side plane rear, in the operating case lying on top 28 the bottom plate 1 and are U-shaped both when viewed from above on the base plate 1 as well as in the side view according to 3, the respective bearing slot 11 in the slot depth is an end bearing surface for one end the wheel axis 9.
- an upstream locking lug 13 which is radial to the wheel axis 9 is directed and as a securing means for the wheel axle 9 serves in the assembled operating position.
- Wheel arches 8 assigned flanks 15, which under one acute angle 16 inclined to the level of the base plate 1 is that there is a difference between the remaining distance between Wheel circumference and wheel arch results in increased distance.
- this flank can, for example, be a flat screwdriver 17 are inserted into the wheel arch 8 so that when tilting over the between the lifting flank 15 and the plane of the Base plate 1 formed edge 18 by the cutting edge 19 of the Screwdriver a lifting torque to the extent of the concerned wheel can be exercised, the Main force component to the open side of the concerned Slot guides 11 is directed.
- the wheel in question can thus against the locking action of the locking lugs 13th pry out of the associated bearing slots 11 again.
- the wheel axles 9 parallel to the longitudinal direction of the base plate 1 or Suction channel 2 and in the main sliding direction at a distance are offset from each other, then the Lifting flanks 15 arranged so that they are each towards the center the bottom plate 1 run out. It results in a simplified access during disassembly as well as the Possibility to get the wheels as close as possible to the concerned Use the longitudinal edges of the base plate 1.
- the locking lugs 13 axially next to the end bearing surface 12 arranged and the bearing slot 11 in the demolding direction only in the area of the latch 13 to the rear 28 of the Base plate 1 designed open.
- the sealing strips 4 provided in the base plate 1 molded grooves 10 extend into Main slide direction laterally next to the support surface 6 in essentially parallel to the suction channel 2.
- the grooves 10 are in the longitudinal direction substantially U-shaped and open to the working level of the floor slab.
- the Groove bottom points openings 22 toward the rear 28 on, so that support webs 23 remain, on which the last foot 24 of the sealing strip 4 supports. additionally are on the opposing flanks 25 Retaining webs 26 are formed, each for opposite groove flank point and as a counter bearing serve for the last foot 24.
- a thin, soft elastic Sealing lip 27 integrally formed, the free lip edge to above that determined by the edges of the suction channel 2 Level and in particular on the determined by the wheels 5 Level protrudes.
- This sealing strip 4 prevents largely the free inflow of air from the back Long edge 21 forth, as does the raised support surface 6 causes.
- the Retaining bars 26 then prevent an unintentional
- the sealing strip falls out of the groove 10. For disassembly only needs one end of the concerned Sealing strip 4 from the groove 10 using a tool to be levered out afterwards by hand or by means of a pair of pliers pulled out of the rest of the groove 10 to become.
