Replaceable brush material carrier for rotary brushes in car washes

Technical field

SUMMARY OF THE INVENTION The present invention provides a replaceable brush material carrier for rotary brushes of car washes.

BACKGROUND OF THE INVENTION

A solution is described in WO93 / 00235, in which there are helical windings of relatively narrow strips of brush material on the drum whose free ends form tangents to the circumference of the winding. Due to the complexity of production and maintenance and low washing ability, this solution has not been adopted.

The known embodiment of rotary brushes for washing motor vehicles generally consists of a shaft on which rings or slats fitted with brush material are inserted. One such solution is described, for example, in DE 10242937 A1. These brush material carriers are non-rotatably mounted on the shaft and are replaceable. To this end, the shafts are longitudinally grooved and the rings or lamellas are provided with projections corresponding to the grooves in the central holes. The brush material is in this case formed of flat or fan-like formations and is seated in pairs of adjacent holes through which it is passed. The brush material is fixed to the carrier by side cut-outs in or by interconnecting the free ends of adjacent fan-like formations. The rotary brush assembled in this way wears unevenly. Before replacing a worn part, which is usually the most exposed part located in the central part of the shaft, it is necessary to remove the entire brush from the washing line. Brush material carriers are then removed from the shaft by pulling them out. This removes the part with worn brush material and when reassembling the shaft is fitted with a new part. Such a solution that is conditional

4tk

I> It · complete removal of the rotary brush from the washing line, which is repaired and re-mounted outside the machine, requiring a longer decommissioning of the washing line.

The replacement of the entire brush is in some embodiments of the rotary brushes replaced by the replacement of only the brush material carrier formed by the flat formation having the faces of the brush material bundles formed on the face, while the other unused carriers remain. The brush material is embedded in beds formed in a flat formation, in which its folded bundles are generally fixed by a retractable wire, which may be either metal or plastic material, e.g. of polyamide.

The brushing material is either sheaves of fibers most often made of synthetic material or strips of polyolefin sponge. The replacement of such a brush material carrier does not require removal of the entire brush from the washing line. In the case of a worn carrier, the flat structure is simply cut with a knife and removed. In order to secure the brush material support, the opposite ends of the flat structure are provided with corresponding holes. The exchangeable carrier thus solved is wrapped around the shaft and the connecting elements, such as rivets or screw connections, are threaded through the holes. Such solutions are described both in US 4658460, where the opposing apertures are in line, and in EP 0524153, where the opposing apertures are spaced apart. Despite a certain advantage over other known solutions of removing only the worn part and replacing it with a new one without removing the rotary brush, the application of the fasteners is laborious and requires craftsmanship that the dishwasher operator does not always possess. If the fasteners are not installed correctly, they can come loose, and the brush carrier can be moved away from the shaft, resulting in damage to the car body.

The essence of the solution

SUMMARY OF THE INVENTION It is an object of the present invention to provide a replaceable brush material carrier for rotary washing line brushes having a flat configuration and having saddles for brush material bundles on the facing surface is provided with pin holes at one edge and corresponding plate holes at the opposite edge that are intended for Pins. Such a solution allows rapid disassembly as in the known embodiment, which is carried out by cutting a flat formation with a knife, but also a quick assembly, to which a hammer is sufficient to drive the pins into the disc fuses.

In such a replaceable carrier, which is formed by a flat formation, both the face and the reverse side are easily accessible. The saddles are therefore perfectly accessible and can be fitted with a folded brush material. The reverse side is also accessible for handling the retractable wire.

The flaps through which the holes can be closed prevent the plate fuses from falling out of the seat holes during handling and transport.

From a production and assembly point of view, it is advantageous if the flap is part of a flat structure with which it is hinged.

For perfect locking of the flap in the seat opening, it is suitable that the flap is provided with a catch for locking the flap with the flat formation in the stowed position, for example with a retractable wire.

It has proven to be perfect for fixing the flap when the free end of the flap is terminated by a latch corresponding to a recess in the face of a flat formation.

 «*

To avoid possible scratching of the washed body, it is advisable that the flap exceeds the pin which is thereby protected.

In order to perfectly transmit the rotational movement of the shaft to the flat structure and thus to the brush material bundles mounted thereon, it is suitable that the driving lugs project from the back surface at a mutual spacing corresponding to the circumferential spacing of the longitudinal grooves of the rotary brush shaft.

In order to avoid overlapping or abrasion of the retractable wire in contact with the shaft, it is desirable that spacers protrude beyond the thickness of the retractable wire from the back surface of the flat formation.

Description of an exemplary embodiment

The flat structure 1 has seats 11 for brush material bundles 2 on the face surface. The flat structure 1 is provided at one edge with holes 12 for pins 3. On the opposite edge it is provided with saddle holes 13 for disc locks 4 intended for pins 3. The saddles 11 are fitted with a folded brush material 2. On the back face 1b, the flat structure 1 is provided with a retractable wire 5 forming a continuous loop around the individual bundles of brush material 2. The retractable wire 5 passes sequentially through the individual saddles ¹¹ . . Spacing projections 19 protrude from the back surface 1b and exceed the thickness of the retraction wire 5. The retraction wire 5 is made of polyamide. The seat openings 13 with disc locks 4 are lockable with flaps 14. The individual flaps 14 are connected to the hinge 15 by a hinge 15. The L4 flap is provided with a groove-shaped catch 16 for securing the flap 14 to the flat formation 1. , which is not shown in the drawing. The free end of the flap 14 is terminated by a latch 17 which corresponds to a recess 17 'in the face 17 and of the flat formation 1. The flap 14 in the closed position exceeds the pin 3. The tabs 18 project from the back face 18. longitudinal grooves of the rotary brush shaft H.

A wire harness loop 5 is inserted from the back surface 1b from the back surface 1b. A bundle of brush material 2 is inserted into the loop and is seated in the seat H by pulling the wire 5. Subsequently, the wire harness loop 5 is inserted into the side seat 11. 2, all seats 11 of the flat formation 1 are successively fitted with the brush material 2, as shown in FIG. Insert the disc locks 4 into the seat openings Γ 3. The seat openings 13 are then closed by the flap 14 so that the flap 14 is folded over by bending the hinge Γ5. The latches 17 engage in the recesses 17 'and are secured in this position by the loop of the binding wire 5, which latches behind the catch 16. The replacement brush carrier 2 thus prepared is ready for mounting on the rotary brush shaft H. In order to replace the worn carrier, the worn carrier is first removed from the shaft H, for example by cutting in the direction of the shaft axis H. Subsequently, the prepared replacement carrier according to the invention is wound around the shaft H. It is necessary that the driving lugs 18 engage the longitudinal grooves of the shaft H. Subsequently, the opposite edges are folded as shown in FIG. The pins 3 projecting outside the shaft H are inserted into the seat holes 13 and thus into the disc fuses 4 and secured in this position by a hammer blow.
