description

The present invention relates to a grill cleaning brush for cleaning grill means, in particular a grill grate, a grill plate or the like, comprising a handling element and a brush head in particular integrally connected thereto.

In known grill brushes a plurality of individual bristle tufts are usually used at the bottom usually on its underside, so that a cleaning brush is formed, in which the bristles relative to the brush head substantially perpendicular down to stand with them a grill, a grill plate or to clean the like. Partly known grill brushes also have bristle tufts on plastic brush head inserts, which are exchangeable.

In such grill cleaning brushes, the problem often occurs that the bristles are deformed during cleaning of a grill grate by the applied pressure and soft to the side, so that the bristle tufts are no longer aligned substantially perpendicular to the brush head, but are bent to the side, which Cleaning performance significantly worsened. It may even happen that the bristles of such Griil- cleaning brushes are so severely bent during intense use that they break or that the brush has areas in which no cleaning effect can be achieved. Once such signs of wear occur, the grill cleaning brush as a whole or its entire, brush bristle Bürstenkopfschelsel must be disposed of.

The object of the invention is to provide a grill cleaning brush which overcomes or at least reduces the above disadvantages. To solve this problem, it is proposed that the grill cleaning brush comprises at least two individual brushes arranged substantially parallel to one another and detachably connected to the brush head.

Through the use of detachably mounted single brushes, these single brushes are individually interchangeable if necessary, so that after wear of the individual brushes not the entire grill cleaning brush or a whole brush head must be disposed of. This leads to a material savings and reduced costs and also allows the grill cleaning brush, in particular the handling element and the brush head can be made of high quality materials, which is important from a design point of view.

According to a preferred embodiment, the individual brushes are designed as round brushes, in particular spiral brushes. It is proposed that mutually adjacent round / spiral brushes are arranged such that the substantially radially projecting bristles of the round / spiral brushes overlap at least partially.

By such a parallel arrangement of round / spiral brushes with partially overlapping bristles brush areas are defined in which a bar of the grill can be taken between two round / spiral brushes and is cleaned by both round / spiral brushes. The bristles of the round / spiral brushes are also aligned substantially radially with respect to the bar of the grill, so that they achieve a maximum cleaning effect.

Preferably, the round / spiral brushes are rotatable about their longitudinal axis, so that after wear of a bristle area, the round / spiral brushes can be rotated by, for example, about 90-120 °, so that unused bristles cause the overlapping area of bristles of adjacent rounds, which primarily causes the cleaning effect. / Make spiral brushes. It should also be noted that the bristles of the round / spiral brushes have a radial length of preferably about 5 - 10 mm. Such relatively short bristles, together with a suitable bristle density, lead to a high stability of the bristles overall, which additionally increases the cleaning performance 5 of the brush. Furthermore, the stability of the bristles is also positively influenced by the overlap and the intermeshing of radially projecting bristles of adjacent round / spiral brushes.

The overlapping bristles then act while cleaning the grill means lo also rotationally inhibited, so that the single brushes do not turn easily and unintentionally in normal use.

The round / spiral brushes are preferably supportable or supported at their longitudinal ends in respective brush holding elements arranged on the brush head.

In order to simplify the replacement of individual round / spiral brushes, it is proposed that at least one of the brush holder elements is detachably connected to the brush head. In this case, the brush holder

20 be fastened or fastened by means of a screw on the brush head, wherein the screw is preferably passed through an opening formed in the brush head and can be brought into engagement with an internal thread formed in the brush holder element. Of course, in addition to a screw connection between brush holder element and brush

25 tenkopf also other, the forces during cleaning resisting fasteners conceivable, in particular locking connections, clip connections and the like.

In the case of the screw connection, the brush head preferably has locking means on its underside facing the cylindrical brushes, which prevent the movement of the brush holder element in a plane orthogonal to the axis of the screw in the fastened state of the brush holder. According to a preferred embodiment, the locking means by formed on the underside of the Bϋrstenkopfs projecting cams, which engage in corresponding openings in the releasable brush holder member. Thus, a twisting of the brush holding member about the screw axis due to the engagement between the cam and openings is prevented, so that the circular / spiral brushes can not be moved from their parallel arrangement during cleaning.

The other brush holder is preferably fixedly connected to the brush head. However, it is also conceivable that both brush holder elements are detachably connected to the brush head, in particular via a respective screw connection. If the other brush holding element is firmly connected to the brush head, this simplifies the replacement of individual brushes, since the connection of the individual brushes must be solved only on one side, ie only with a brush holding element.

The brush holding elements preferably have at least one respective receiving element, in which at least one insertion opening is provided for receiving a longitudinal end of the round / spiral brushes. Furthermore, the brush holding elements preferably comprise a respective protective element, by means of which the free longitudinal ends of the round / spiral brushes and the at least one receiving element are covered in the longitudinal direction of the round / spiral brushes. As a result, the inserted into the insertion of the receiving elements wire or pin portions of the respective round / spiral brush are not visible, which on the one hand from the design point of view leads to an attractive exterior of the grill cleaning brush and on the other hand reduces the risk of injury to such wire sections.

The protective elements extend in the mounted state preferably from the underside of the brush head down and have a lower contour which is wave-shaped orthogonal to the longitudinal direction of the round / spiral brushes, such that a trough substantially with the overlap region of the radially projecting bristles of two adjacent round / spiral brushes in the longitudinal direction and that a wave crest essentially in alignment with the longitudinal axis of a single round / spiral brush in the longitudinal direction. However, this wavy contour is only a preferred embodiment; Also conceivable is a straight course of this contour or another suitable shape.

Such an embodiment of the protective elements makes it possible for one or more bars of a grill grate to be received in the troughs of the protective elements and for the brush to be supported on the protective elements on the grill grate. Since the protective elements are made of a harder material than the bristles of the round / spiral brushes, it is possible to prevent the overlapping bristles of the individual round / spiral brushes from being subjected to heavy loads and thus being damaged very quickly. In particular, the buckling of the bristles occurring in known grill cleaning brushes can be largely prevented. Furthermore, these protective elements can also be used to carry out a kind of rough cleaning of larger dirt particles adhering to the bars of the grill grate, since the protective elements first come into contact with such dirt particles during a reciprocating movement of the grill cleaning brush along the bars of the grill grate. Thanks to the protective elements, even very hard, heavily encrusted residues can be easily removed, since the protective elements are correspondingly hard.

The handling element of the grill cleaning brush preferably comprises a handle handle and a handle, which is in particular made cylindrical. To keep the grill cleaning brush, it is proposed that an opening is provided at the end remote from the brush head end of the handle, in particular for hanging the grill cleaning brush on a hook. This opening preferably follows the handle of the grill handle. But it is also conceivable to attach a handle without handle directly on the brush head, for example, as a vertically upstanding handle or as a handle loop on the brush head.

For optimal cleaning effect on grills made of iron, steel, stainless steel steel and the like. It is proposed that the bristles of the individual brushes are made of metal, preferably made of brass. Brass has the advantageous property that abrasion of brass, which remains during brushing of the grill on this, does not contribute to the formation of flash rust, so not to corrosion, for example, a (cast iron) grate.

The handling element, the brush head and the brush holding elements are preferably made of metal, in particular made of stainless steel. This makes it possible to produce a sturdy and shapely grill cleaning brush, the choice of stainless steel also having to be seen in connection with the exchangeable single brushes, since the grill cleaning brush is designed to use the handle handle, the brush head and the brush holding elements for a very long time and only the individual round / spiral brushes are replaced if necessary. By the use of stainless steel also in the brush holding elements, which include the above-mentioned protective elements, the protective elements, as already described, support the cleaning of the grill.

The invention will now be described by way of example and not by way of limitation with reference to the accompanying drawings.

Bottom. Fig. 4 is a schematic representation of the grill cleaning brush located on a bar of a grill.

FIG. 5 is a simplified cross-sectional view taken along line V-V of FIG. 4. FIG.

Fig. 6 is an illustration of lying on a substrate

Grill cleaning brush to illustrate their special shape.

Fig. 1 shows in the partial figures a) and b) is a side elevational view and a plan view of an embodiment of a grill cleaning brush 10. The grill cleaning brush 10 comprises a handle handle 12 with a cylindrically shaped handle 14, which together form the handling element. The handle 14 is followed by an eye-like opening 16, by means of which the grill cleaning brush 10 can be hung for example on a hook for storage.

In its front region, the grill cleaning brush 10 comprises a brush head 18, on the underside 20 of which several, in the exemplary embodiment, four spiral brushes 22 are arranged. These spiral brushes 22 are connected at their longitudinal ends by means of a first brush holding member 24 fixedly connected to the brush head 18 and by means of a brush holding member 24 'detachably connected to the brush head 18. In this case, the front, releasable brush holder 24 'is fixed by means of a knurled screw 26 on the brush head 18, so that the brush holder 24' can be removed from the brush head 18 by loosening the screw. It should be noted that the representation of the grill cleaning brush as a whole and also the spiral brush 22 is simplified and schematic, in particular, in the spiral brushes no individual bristles are shown.

Fig. 2a) shows a front view corresponding to the arrow II of Fig. 1a) From the illustration it can be seen that the knurled screw 26 passes through an opening in the brush head 18 and engages with an internal thread formed in the brush holder element 24 ', so that the brush holder element is in contact with the brush head 18 and the four spiral brushes 22 attached thereto 24 'in the direction of the screw axis S to the brush head 18 is attracted. In order to prevent a rotation about the screw axis S, protruding cams 28 are provided on the brush head 18, which engage in corresponding openings 30 in the brush holding element 24 ", which can be seen in detail in FIG Such cams 28 are arranged laterally on both sides of the knurled screw 26 in order to ensure as free as possible attachment of the brush holding element 24 'to the brush head 18.

The brush holding members 24, 24 'have protective members 32, 32' covering the longitudinal ends of the spiral brushes 22 toward the front and rear in the longitudinal direction of the spiral brushes 22. In this case, the protective elements 32, 32 'extend from the underside 20 of the brush head 18 downwards and have a lower contour 34, which is wave-shaped. In this case, the wave-shaped contour 34 is configured such that a wave trough 36 is aligned substantially with an overlap region U of radially projecting bristles of two adjacent spiral brushes 22 in the longitudinal direction, and that a wave crest 38 is aligned substantially with the longitudinal axis L of a single spiral brush in the longitudinal direction.

Fig. 3 shows a view of the brush head 18 and the spiral brush 22 from below in a schematic representation. It can be seen that the spiral brushes 22 are received in receiving elements 42, 42 'via a central wire 40 forming their respective longitudinal axis L, the respective longitudinal ends 44, 44' being inserted through insertion openings in the receiving elements 42, 42 '. The spiral brushes 22 are thus received in the mounted state between the receiving elements 42, 42 'in the brush longitudinal direction L substantially free of play. From the representation 3, it can also be seen that the protective elements 32, 32 'surround the receiving elements 42, 42' and the respective longitudinal ends 44, 44 'of the spiral brushes 22 and cover them in each case in front and behind. Furthermore, from FIG. 3, the overlapping area U 5 is also visible, which is formed by the bristles of adjacent spiral brushes 22 protruding radially from the central wires 40.

4 is a schematic partial sectional view along the longitudinal axis L of the spiral brushes 22 in the case of a grill cleaning brush lying on a bar 46 of a grill grate. As can be seen from this illustration, the front protective element 32 "forms a type of scraper which can at least partially remove dirt particles 48 exceeding a height indicated by a dashed line 50. Smaller dirt particles 52 adhered to the bar 46 become radial projecting bristles i5 of two adjacent spiral brushes 22 away from the bar 46 by reciprocating the grill cleaning brush.

FIG. 5 shows, in a highly simplified schematic cross-sectional view corresponding to the section line V-V of FIG. 4, the overlapping region of FIG

₂ o radially projecting bristles 54 of adjacent spiral brushes 22. Since the removal of dirt particles 52 effective bristles 54 are aligned radially to a large extent to the rod 46 of the grill, this rod 46 is in an upper, the brush-facing peripheral region of about 120 - 180 ° completely and thoroughly cleaned. To prevent that

25 the spiral brushes 22 are stressed too much, d. H. the bristles 54 are bent too much during cleaning, the grill cleaning brush with the troughs 36 of the protective elements 32, 32 'rest on the rod 46, which corresponds to a maximum penetration depth of the rod in the overlapping region U of the bristles of the spiral brush 22. It can through

30, the protective elements 32, 32 'are thus prevented that the rod 46 passes between the central wires 40 during cleaning and is then arranged at the same height or above the central wires 40 of the spiral brushes 22. It is therefore ensured that the rod 46 is always in the overlay. Abutment area U is to achieve an optimum cleaning effect by the radially extending bristles 54.

If the distance from adjacent bars 46 of a grill grate does not correspond exactly to the distance between adjacent troughs 36 of the protective elements 32, 32 ', nevertheless at least one bar 46, which is essentially accommodated in a trough 36, can be cleaned optimally with the brush.

The individual spiral brushes 22 can be rotated about their longitudinal axis L relative to the brush head 18 so that worn bristles can be rotated upwardly from the bottom to the bottom 20 of the brush head 18 to bring unused bristles into the overlap area U.

FIG. 6 shows, in a simplified schematic representation, a grill cleaning brush 10 lying on a base 50, for example a table or storage surface. From this representation, it can be seen that the dimensions of the handle 14, the shape of the handle 12 and the dimensioning of the protective elements 32 , 32 "is coordinated so that when placing the grill cleaning brush 10 on the substrate 50 and when abutting the front protective element 32 'at an edge 52, such as wall or vertical table boundary, the individual brushes 22 with the substrate 50 and the edge 52 is not or This advantageously results in that the bristles of the single brushes 22 are not deformed below the weight of the grill cleaning brush 10 in such a storage of the grill cleaning brush 10, whereby the cleaning performance could be worsened will be here It also prevents contaminated brushes from coming into contact with the substrate 50.

Finally, it should also be noted that the spiral brushes presented here as single brushes 22 could also be interconnected, so that they could be provided as a brush set, for example as a set of four for the presented embodiment. However, when the spiral brushes 22 are not joined together and are discrete, they can be placed side by side on a flat surface and interconnect with each other by the engagement of the radially projecting bristles in the overlapping area U, so that four spiral brushes 22 placed next to each other in the Brush holder 24, 24 "is easily possible.

The number of spiral brushes is not limited to four, but any number greater than or equal to two can be used to achieve the advantageous cleaning effect of parallel spiral brushes for at least one bar of a grill.

Although in the embodiment, only the cleaning of a grill was addressed, it is clear that such a grill cleaning brush is also used for cleaning grill plates, such as metal or stone, and barbecue skewers. The term grill grid or grill plate can in principle be applied to all rust-like, serving for heating food items, for example, on oven grates or baking trays.
