Definitions

  • the present invention relates in one aspect to a segment, in particular a brush, cleaning, grinding or polishing segment for detachable arrangement on a rotatably mountable carrier of a plate, in particular to form a disc broom or a cleaning, grinding or polishing plate.
  • the invention further relates to a carrier for forming a circular broom and a correspondingly equipped circular broom which has such a carrier with a plurality of segments arranged thereon, for example brush or polishing segments.
  • Common sweeping and cleaning machines or devices have a motor-driven and correspondingly rotatable head, i.e. a drive head on which a support for the circular broom is arranged in a rotationally fixed manner.
  • Common disc brooms wei sen a disc-shaped disc body, on which a plurality of bristles are arranged, facing away from the disc body with its free end, typically based on the axis of rotation of the disc body approximately axially, or under a predetermined angle axially and radially outward inclined, aligned.
  • the present invention is based on the object of providing an improved plate for forming a plate brush or for forming a cleaning, grinding or Po lierteller and segments provided for this purpose, which can be mounted on the plate as simply and intuitively as possible and, if necessary, also individually and independently are interchangeable from each other.
  • the assembly and / or disassembly of individual segments on or from a carrier of the circular brush should be carried out tool-free as possible, that is, without the aid of fastening tools.
  • the segments and the corresponding carrier should have a structure that is as simple and robust as possible. They should be able to be produced as simply and inexpensively as possible.
  • the segments should have an improved ecological balance. They should be able to be produced in a way that conserves resources.
  • the segment provided according to the invention is designed for detachable arrangement on a circular, typically disk-like carrier of a circular broom or a cleaning, grinding or polishing plate and is provided for this purpose.
  • the segment has a segment body. If the segment is designed as a brush segment to form a circular broom, several bristles or bristle tufts protrude from its underside.
  • an abrasive grain and / or a fiber structure for example in the form of a fabric or a fleece, is arranged on the underside of the segment body.
  • the segment body has, based on the axis of rotation of the carrier adjacent to a radially inner inner edge and spaced from an outer side edge of the segment body with respect to a circumferential direction of the carrier, a segment guide extending in the radial direction.
  • the segment guide is designed or designed to cooperate with a carrier guide which is designed to correspond or complement this on the carrier or is arranged on the carrier for the purpose of arranging or fixing the segment on the carrier.
  • the carrier guide extends, based on the axis of rotation or based on a central area of the carrier, also in the radial direction.
  • the segment guide as well as the carrier guide can be elongated guides which have a predetermined extension in the radial direction.
  • the segment guide or the carrier guide enables an assembly direction of individual segments in the radial direction, typically from radially outside to radially inside.
  • the segment guide or the carrier guide can be sliding guides which mutually engage with one another well before the segments on the carrier reach a final assembly position. In this way, a particularly simple, reliable and intuitive assembly of individual segments on the carrier is made possible.
  • the segment guide and the carrier guide can have corresponding straight and mutually sliding guide surfaces that are formed, for example, by corresponding in the western straight or flat side edges and / or side cheeks of the carrier guide and / or segment guide. This allows a particularly simple and low-friction sliding along one another of the relevant guide surfaces of the segment guide and carrier guide.
  • the segment guide of the segment is located within the segment body in relation to the axial direction.
  • the segment guide is based on the later axial direction of the segment in its arrangement on the carrier between tween an upper side facing the carrier and a lower side of the segment body facing away from the carrier.
  • the side edges of the segment bodies typically run in the radial direction.
  • Several segment bodies arranged on the carrier typically form an annular or circular disk-like contour.
  • the individual segment bodies can be designed in the manner of a circle or ring segment. Due to the side edges running in the radial direction, opposite side edges of a segment run approximately conically towards each other in the direction of the radial center, with radially inwardly directed imaginary extensions of opposite side edges of the segment body on or on the axis of rotation cut of the carrier.
  • This geometry requires that segment bodies adjoining one another in the peripheral direction only come into contact with their mutually facing side edges when they reach their final assembly position on the carrier.
  • segment guide adjoins the radially inner inner edge of the segment body, the earliest possible radial guidance of individual segment bodies on the carrier can take place in the course of a radially outwardly inwardly directed Montagebe movement. This simplifies assembly.
  • the segment guide adjoining the inner edge of the segment body also proves to be advantageous in terms of production technology.
  • the segment body can, for example, be milled, cut out or punched out of a blank in order to form a corresponding segment guide.
  • segment guide is designed or arranged at a distance from an outer side edge of the segment body on the segment body, it can also be achieved that the segment body only requires a single segment guide, which interacts with a correspondingly configured carrier guide to radially, axially and / or to be guided tangentially on the carrier or to be fixed to it.
  • This made light a reduction in the number of segment guides per segment body to a minimum, whereby the complexity of the segment body, but also the complexity of the carrier guide and thus the complexity of the carrier can be reduced in an advantageous manner.
  • only a single carrier guide can be provided on the carrier for each segment, which can interact with a single segment guide per segment for fixing or arranging the segment on the carrier.
  • the segment guide is located at a predetermined distance from the outer side edges of the segment body in the circumferential direction.
  • the segment guide is located between opposite side edges of the segment body.
  • the segment guide can be located approximately in the middle between the side edges.
  • the segment guide can extend parallel to an imaginary center line or axis of symmetry of the segment body running in the radial direction and centrally between the side edges.
  • a central segment guide or located between opposite side edges enables a particularly simple and uncomplicated interaction of the segment guide with a corresponding or complementary carrier guide configured on the carrier, especially if only a single segment guide is provided on the segment.
  • the central arrangement or configuration of the segment guide on the segment body enables, in particular, a tilt-free or tilt-free assembly of the relevant segment on the carrier.
  • one of the segment guide and Trä ger arrangement has an extension extending in the radial direction, which can be inserted into a correspondingly designed, radially extending receptacle of the other of the segment guide and carrier guide.
  • the support guide has a corresponding or complementary design, radially extending receptacle into which the extension of the segment guide can be inserted.
  • the carrier guide configured to be complementary or corresponding thereto has an extension extending in the radial direction which can be inserted into the receptacle.
  • the segment or the segment body with its receptacle adjoining the radial inner edge can be pushed onto an extension which is typically provided on the underside of the carrier and extends radially outward.
  • segment guide is provided with a receptacle, this typically extends radially inward from the inner edge of the segment body.
  • the extension of the carrier guide provided on the carrier typically extends radially outward.
  • the extension typically extends radially inward from the inner edge of the segment body. It projects more or less radially inward from the inner edge of the segment body.
  • the Trä ger arrangement typically has a radially inwardly extending receptacle.
  • the inclusion of the segment guide or support guide is limited in the circumferential direction by two opposite side walls.
  • the side cheeks are typically designed to correspond to the side cheeks of the extension of the other of the segment guide and carrier guide.
  • the distance between the iswan conditions in the circumferential direction of the receptacle typically corresponds to the distance herewith corresponding side cheeks of the extension in question.
  • the distance between the side walls of the extension in the circumferential direction is slightly smaller than the clear distance between the side walls of the respective receptacle, so that the extension in question can be inserted into the receptacle without tilting or tilting.
  • the uptake and the continuation can be one, based on the level of the segment ment body or the carrier, have substantially rectangular contour.
  • Opposite side cheeks of the extension and / or recordings can extend approximately parallel to each other. The side cheeks can in particular also extend parallel to an imaginary and radial center line of the segment or to an imaginary radial line of the carrier that intersects the axis of rotation.
  • the extension and receptacle can point away from its receptacle edge in the radial direction and taper in the circumferential direction, for example pointed or conically tapered.
  • the extension can also have a conical or tapering free end which can be inserted into a receptacle designed to correspond or complement it.
  • the receptacle has a radial end wall.
  • the receptacle is limited in the radial direction by an end wall.
  • the extension configured to complement this is also provided with an end face which, when the segment reaches a final assembly position on the carrier, comes to rest against the end wall.
  • the mutual contact between the end wall and the end face limits the radially inwardly directed assembly movement of the segment on the carrier.
  • the segment or the Segmentkör is supported on the carrier radially inwards via the alternating contact position of the end wall and the end face.
  • the end walls of the receptacle and extension can rest directly against one another and to this extent form reciprocal end stops for a defined final assembly position of the segments on the carrier.
  • the aforementioned radial support is particularly advantageous if the outer edge of a segment should collide, for example, with objects, for example a curb or a wall.
  • the carrier which is typically made of metal, can be kept free from damage here. Any damage as a result of collisions with objects are accepted for the replaceable segment, which is designed as a wear part.
  • the reusable carrier which can typically be arranged on a cleaning or sweeping machine, is, however, protected from corresponding damage.
  • the end wall has a mechanical coding which is designed to correspond to a counter-coding formed on the extension.
  • the counter-coding is typically located on the front of the extension.
  • the coding can have one or more radial extensions or radial depressions.
  • the mechanical coding can have a tapering projection which can engage in a receptacle or recess of the counter-coding which is designed in a corresponding or complementary manner in the radial direction.
  • Complementary or mutually corresponding codes and counter-codes in the area of the end wall or in the area of the end face make it possible for the segment bodies provided for a specific carrier to be equipped, for example, with a code that corresponds to the carrier-side counter-coding.
  • Unsuitable segment bodies which are equipped with a coding that does not match the counter-coding provided on the carrier can therefore not be arranged on the carrier. In this way it can be avoided that segment bodies not provided for a specific carrier are used with such a carrier, but that only such segments or segment bodies can be arranged on a carrier which is designed for such segments or segment body .
  • a type of positive connection between the receptacle and the extension, thus between the segment and the carrier, can in particular be formed, based on the circumferential direction of the carrier. If the receptacle and the extension are subject to a certain mechanical play, or if the extension, viewed in the circumferential direction, is smaller by a predetermined gap size than the clear width of the correspondingly designed receptacle, a certain play-prone mounting of the segment body on the carrier can be provided be.
  • any possible tilting of the segment relative to the carrier caused by the gap between the receptacle and the extension can be compensated for or largely eliminated or prevented.
  • the receptacle has, viewed in the axial direction, on at least one of the upper side or the lower side of the segment body on a cover section which protrudes up to the inner edge.
  • the receptacle can be designed to be closed on the upper side or on the lower side of the segment body.
  • the acquisition can also be formed, for example, as a blind hole, slot or groove on the inner edge of the segment body. In some configurations it is provided that the recording to the underside of the segment body and to the inner edge of the segment body is open out staltet, but that the receptacle is closed by the cover portion towards the top of the segment body.
  • the cover section extends between the opposite side walls of the receptacle. It connects the opposite side walls of the recording, so to speak. This creates a recess that is accessible from the underside of the segment and can, for example, be pushed onto the extension that corresponds to this.
  • This configuration proves to be particularly advantageous when a radially outwardly protruding extension is arranged or formed on the underside of the carrier, which is arranged or formed thereon while maintaining an axially and radially externally accessible gap.
  • the axial gap width here corresponds at least to the axial thickness of the cover section.
  • the receptacle can be introduced with its Deckelab section from radially outside to radially inside into the space or into the gap between the extension and the underside of the carrier or a carrier disk. In this way, an axial securing of the segment on the carrier can already be achieved by plugging the receptacle onto the extension.
  • the segment or the segment body is provided with a smooth upper side which is essentially free of projections.
  • This enables a particularly simple guidance of the segment body along the underside of a carrier disk of the carrier.
  • the upper side of the segment body can act as a sliding surface, which can slide along an essentially flat carrier disk on the lower side until the final assembly position is reached on the carrier. This further simplifies the assembly of the segment on the carrier.
  • the receptacle extends continuously from an upper side to the lower side of the segment body.
  • at least one fixation of the segment body or the segment relative to the circumferential direction on the carrier can be achieved through the mutual engagement of the receptacle and the extension.
  • Further fastening means are provided for its axial fixation.
  • a continuously extending from an upper side to the lower side of the segment body on acquisition is particularly easy to implement in terms of manufacturing. This enables, for example, the formation of the segment body as a stamped part.
  • the radially inner inner edge has a further mechanical coding which is designed to interact with a further counter-coding of the carrier designed correspondingly to this.
  • the further mechanical coding can be configured on the inner edge of the segment body instead of the mechanical coding already mentioned.
  • the end wall of the receptacle can be designed free of coding, which can prove to be particularly simple in terms of production technology, especially when the receptacle is designed as a groove.
  • the segment body can, however, also be provided twice, namely with a first coding in the area of the end wall and with a second coding in the area of the inner edge.
  • the double mechanical coding can provide a type of double or multiple form fit at least in the circumferential direction, so that a particularly good tilt-free and play-free final assembly position of the segment on the carrier can be achieved.
  • the segment body has a securing element which is designed to form a radial fixation of the segment on the carrier corresponding to a counter-securing element which can be arranged on the carrier or is formed on the carrier.
  • the securing element of the segment is arranged on an upper side of the segment body or it is accessible from the upper side of the segment body.
  • the counter-securing element can also be arranged or formed on the upper side of the carrier and accordingly of course also be accessible from above. This enables a particularly simple, possibly tool-free fixing and assembly of the segment on the carrier.
  • the securing element can be, for example, a hook which protrudes radially outward with its free end and which can be introduced from radially outward to radially inward into a correspondingly slotted area bordering the outer edge of a carrier disk of the carrier.
  • the counter-securing element on the side of the carrier can be designed, for example, as a tension lock, a toggle lock or a safety bracket, which can be operated without tools and which can be releasably connected in a form-fitting manner to the hook configured on the segment body or arranged thereon.
  • the design or arrangement of the securing element on the top of the Segmentkör pers proves to be advantageous in terms of assembly technology.
  • the carrier no longer necessarily has to be removed from a sweeping or cleaning machine to be dismantled.
  • the accessibility to the securing element or counter securing element from the top of the carrier has proven to be particularly advantageous from the point of view of operating comfort.
  • the securing element is let into the segment body, embedded or integrated into it.
  • the securing element can be embedded or embedded or integrated flush with the surface of the segment body.
  • the securing element can be, for example, a drive-in nut, a weld nut or an internal thread of a bore in the segment body accessible from above.
  • a wide variety of securing elements are used as required.
  • the securing element can be screwed, welded or otherwise attached to the segment body, for example in the form of a metal hook.
  • the securing element can also be designed, for example, as a drive-in nut or as a weld nut, which is let into the plastic body of the segment or driven into it and anchored in it in a form-fitting or materially bonded manner.
  • a screw opening, screw hole and / or a screw arranged on the carrier can function as a counter-securing element on the carrier.
  • a threaded hole on the upper side of the segment body can come into contact with a passage opening on the carrier so that a screw or similar securing element for the axial and radial fixation of the segment body or the segment is provided from above can be screwed or screwed onto the carrier.
  • the segment body is a plastic body or metal body that is milled or cut out or punched out of a blank.
  • plastic or metal bodies can be produced in a particularly simple and efficient manner. Pro duction and manufacturing costs for such segments can be reduced in this way.
  • Embodiments in which the segment guide has an extension extending in the radial direction apply to all of the features described above with regard to the extension as belonging to the segment guide and thus to the segment.
