Claims (9)

PATENT CLAIMS
1.Vacuum cleaner nozzle with strips of flexible material arranged in front of and behind the suction channel over the entire working width of the nozzle in grooves provided in the suction mouthpiece, characterized in that each strip (4) consists of a flexible thin lip (5) with a molded stiffening part (6) and the latter is in one piece with locking studs (7) projecting at a distance from one another, which can be pressed into corresponding openings (8) in the bottom (9) of the groove (3) of the sliding sole (1).
2. Vacuum cleaner nozzle according to claim 1, characterized in that each strip (4) is made of rubber.
3. Vacuum cleaner nozzle according to claim 1, characterized in that the stiffening part (6) has a steel wire core (10).
4. Vacuum cleaner nozzle according to claim 1, characterized in that a fabric is embedded in the stiffening part (6).
5. Vacuum cleaner nozzle according to claim 1, characterized in that a material is incorporated into the stiffening part (6), which has a greater Shore hardness than the lip (5) and the snap-in knobs (7).
6. Vacuum cleaner nozzle according to claim 1, characterized by snap-in knobs (19) with parallel side walls (20, 21). (Fig. 3)
7. Vacuum cleaner nozzle according to claim 1, characterized by snap-in knobs (22) whose side walls (23, 24) taper conically in the direction of the lip (5). (Fig. 4)
8. Vacuum cleaner nozzle according to claim 1, characterized by snap-in knobs (7), the side walls (11, 12) of which converge upwards in a triangular shape and have undercuts (13, 14). (Fig. 2)
9. Vacuum cleaner nozzle according to claim 8, characterized in that the undercuts (13, 14) projecting parts continue as legs (15, 16), so that tabs (17, 18) result from the lip (5) seen are spread apart. (Fig. 2)
DESCRIPTION The invention relates to a vacuum cleaner nozzle with strips of flexible material arranged in front of and behind the suction channel over the entire working width of the nozzle in grooves provided in the suction mouthpiece.
This prior art has become known from DE-GM 79 12 825. As can be seen from this, the strips mentioned, which are provided for improving the fluidic suction, can be inserted into grooves and therefore - as also indicated there - require lateral securing in order to prevent them from sliding out.
The invention has for its object to avoid this disadvantage and to provide a vacuum cleaner nozzle of the type mentioned, in which the strips can be easily and securely attached and also removed without the aid of a tool, i.e. it is easy to replace worn strips with new ones.
This object is achieved according to the invention in that each strip consists of a flexible thin lip with an integrally formed stiffening part and the latter is in one piece with locking knobs projecting at a distance from one another, which can be pressed into corresponding openings in the bottom of the groove.
Advantageous further developments result from the features of claims 2 to 9.
Some preferred embodiments of the invention are described in more detail below, for example, with reference to the schematic drawings; show it:
1 shows a detail from the sliding sole in a perspective view with the strip fastened therein;
2 shows a cross section through a bar stiffened with a steel wire core;
3 shows a bar with rectangular snap-in knobs;
Fig. 4 is a bar with trapezoidal locking knobs.
The vacuum cleaner nozzle according to the invention has 2 grooves 3 for strips 4 made of flexible material, preferably rubber, in the sliding sole 1 in front of and behind its suction channel. Each strip 4 consists of a flexible thin lip 5 with a molded-on stiffening part 6, which is one-piece with locking knobs 7 projecting from one another. Openings 8 corresponding to the latter are located in the bottom 9 of the groove 3. In order to fasten a strip 4 and to secure it against falling out as well as being pushed out laterally, it is sufficient to press the latching knobs 7 into the openings 8 in the bottom 9 of the groove 3 .
Since the lip 5 should be much more elastic than the stiffening part 6, which is integral with it, it is expedient to provide the latter with a steel wire core 10. Alternatively, a fabric can be embedded in the stiffening part 6 for better stiffening. A material which has a greater Shore hardness than the lip 5 and the snap-in knobs 7 can also advantageously be incorporated into the stiffening part 6.
In the snap-in knobs 7, the side walls 11, 12 of which converge upwards in a triangular shape, undercuts 13, 14 are additionally provided, which prevent the strips 4 from falling out of the openings 8 due to this barb-shaped design.
The parts projecting beyond the undercuts 13, 14 continue as legs 15, 16, so that flaps 17 and 18 result, which are greatly spread apart from the lip 5, as can be seen from FIG. 2.
In practice it has been shown that snap-in knobs 19 with parallel side walls 20, 21 (FIG. 3) are also expedient. Snap nubs 22, the side walls 23, 24 of which taper conically in the direction of the lip 5, also proved to be advantageous (FIG. 4).
The types of attachment of the strips 4 according to the invention are intended to generally prevent the sliding load resulting from the stress on the forward and backward movement during the cleaning process from affecting the sticking of the strips 4 in the grooves 3.
