The brush construction is entirely made of recyclable plastics.

Description

DESCRIPTION

"RECYCLABLE RING BRUSH FOR USE IN

ROAD AND FLOOR CLEANING VEHICLES”

THE FIELD OF TECHNOLOGY

The invention refers to the technical field of recyclable brushes used in road and floor cleaning vehicles.

THE HISTORY OF THE INVENTION

The recyclable ring brush disclosed in the present invention for use in street and floor cleaning vehicles has not been presented in the past.

To date, ring brushes consist of a metal or plastic ring, of a certain width on the shaft, on which are placed fibers of plastic, metal or other suitable material. They have one or two small fires placed transversely, towards the center of the ring, which ensure the possibility of transmission. Such a ring is shown for example in US00D401254. The ring brushes are mounted on a shaft, side by side, forming a cylindrical brush of a specific fiber length and density. It is often necessary to use spacer rings between ring brushes to reduce the overall cost of the brush. Therefore the ring brushes in use today present as a significant disadvantage the requirement to use shafts of predetermined shape in order to transmit the movement to the brush through the crossfires.

At the same time, another disadvantage is that the final density of the cylindrical brush is proportional to the width of the individual ring brushes and spacer rings used.

A further disadvantage of the cylindrical brushes in circulation, which are composed of ring-shaped brushes, is the impossibility of combining ring-shaped brushes on the same axis, which will be densely distributed in one part and more sparsely distributed in another. In other words, the cylindrical brushes manufactured to date must have a uniform distribution of ring-shaped brushes on their axis.

An additional disadvantage faced by several ring-shaped brushes in use today is the existence of parts made of non-recyclable materials, making the process of separating them significantly time-consuming and laborious, so that one can proceed with their recycling after their end of life.

It is thus an object of the present invention to advantageously address the aforementioned disadvantages and shortcomings of the prior art by proposing an annular brush for use in road and floor cleaning vehicles.

A further object of the present invention is to offer a brush fully recyclable after use, since its manufacture is carried out using only plastic raw materials.

It is a further object of the present invention to provide a recyclable ring brush for use in street and floor cleaning vehicles, capable of being mounted on any vehicle axle, regardless of its shape.

It is a further object of the invention in order to make the aforementioned recyclable ring-shaped brush useful is the possibility of using holes and fiber bundle respectively, which have a larger diameter. In this way, the propulsive capacity to remove waste from the brush increases, contributing to the faster and more efficient cleaning of roads and floors.

A further characteristic of the invention is the presentation of a recyclable cylindrical brush for use in floor and road cleaning vehicles, in which the distribution density of the individual ring-shaped brushes that make it up can be adjusted by the user, using a single product.

Likewise, the advantage of the brush in terms of cost adjustment by the user should be mentioned, offering a wide collection of combinations that adapt and satisfy any cleaning requirements that may arise.

Another feature is the possibility of combining rings with plastic and rings with metal fibers, in the same cylindrical brush, satisfying specific requirements that may exist.

These and other objects, features and advantages of the invention will become apparent in the following detailed description.

DETAILED DESCRIPTION OF PREFERRED APPLICATION

Referring now to the accompanying drawings we will describe exemplary embodiments as well as the manner of assembly and operation of the recyclable ring brush of the invention. The ring brush of the invention consists of an inner ring (1), Fig. 1, made of polypropylene or polyethylene or even a mixture thereof. Its construction from plastic materials contributes to its complete recycling, while at the same time reducing its weight and construction costs. The outer surface of the inner ring (1) is formed with appropriate grooves, of a predetermined shape, with a specific distribution on the ring (1). There are, as can be seen, longitudinal grooves (2) and joining grooves (9), of different lengths. The inner ring (1) can be transparent and have a pin (3), so that it can be placed on the axle of the vehicle and receive its movement. Similarly, the ring (1) may not be transparent, but have an internal square opening (4), Fig. 9, or any other shape, so that it fits on shafts with a corresponding configuration.

The outer ring (5), Fig. 2, is similarly made of plastic, polyethylene, polypropylene or a mixture thereof, with toothed configurations (6) on both sides, which are a continuation of the rim of the ring (5). The configurations (6) are indicative of a parallelogram shape and are at equal distances from each other, without this being mandatory. The only requirement is that the outer ring (5) can be femaled with the inner ring (1), in order to create the annular set. One side of the toothed configurations (6) of the outer ring (5), without being limiting which of them will be, has in each configuration (6) elongated projections (7), to be respectively adapted to the longitudinal grooves (2) of inner ring (1) and form an annular set, while the other side has mating projections (10), of varying lengths, to mate each annular set with the mating grooves (9) of the corresponding neighboring set. On the outer side of the outer ring (5) the plastic cleaning fibers (8) are placed, Fig. 3. The material of the fibers (8) can be made of polypropylene, while the placement of the fibers can be achieved by fusion through melting and cooling of their tip with the corresponding plastic of the surface of the outer ring (5), ensuring the creation of a fully recyclable brush.

As an example and as an alternative, we must mention that metal fibers or any other suitable material can be used, in cases where this is required by the particular use of the brush. Similarly, the placement of the fibers (8) on the outer ring (5) can be carried out in any other known way, as for example by nailing them to the ring using a metal hook.

The inner ring (1) and the outer ring (5) mate with each other, thanks to the longitudinal grooves (2) and the elongated projections (7), as shown in Fig. 4, creating the assembled ring set, Fig. 5. For forming a recirculating cylindrical brush, for use in street and floor cleaning vehicles, the above-mentioned assembled sets, Fig. 6, are successively placed on a pivot.

One of the significant advantages of the invention is the ability to adjust the fiber density (8) of a cylindrical brush assembled from the ring brush sets shown here. As mentioned above, the joining projections (10) of the inner surface of the outer ring (5) have different lengths, as do the joining grooves (9) of the inner ring (1). Therefore, depending on how each set of ring brushes will feminize with the adjacent set, it can cut a cylindrical brush with dense fibers, Fig. 7, a cylindrical brush with a thinner distribution of fibers, Fig. 8, or any other, desired distribution. As it becomes obvious, there is always the possibility of creating a cylindrical brush that will be made of sets of rings, joined together, with a different distribution. In other words, ring-shaped brushes with a dense distribution can be placed in the center along a rotation axis, while ring-shaped sets with a thinner distribution have been joined to the outer points of the axis. This, of course, depends on the particular use of the brush.

At this point it should be noted that the description of the invention was carried out with reference to illustrative examples of application, to which it is by no means limited. Consequently, any change or modification in terms of shape, dimensions, morphology, materials used and construction and assembly components, as long as they do not constitute a new inventive step and do not contribute to the technical development of what is already known, are considered to be included in the aims and objectives of the present invention .
