Abstract
Description
CLEANING ITEM FIELD OF INVENTION The present invention relates to a cleaning element comprising a carrier body to which elongated fringes are attached, the fringes enclosing a central region of the carrier body. BACKGROUND OF THE INVENTION A similar cleaning element is known from document DE 10 2017 004 809 B3. In the known cleaning element, elongated textile fringes are attached at one end to the carrier body. The fringes comprise several interconnected cords made of synthetic fibers. This makes the fringes bulky and gives them a high water absorption capacity. The known cleaning element is used for wet and moist floor cleaning, respectively. The cleaning element is particularly suitable for being squeezed in a rotary centrifuge after cleaning. For this purpose, the cleaning utensil, in which the cleaning element is secured in a basket-shaped receptacle, is pushed into the receptacle, which is then rotated along its longitudinal axis, expelling the excess water from the fringe. It is not necessary to remove the fringe from the cleaning utensil before cleaning and centrifuging. The well-known cleaning agent certainly has a high cleaning capacity, but one problem is the removal of dirt that adheres firmly to the floor being cleaned. BRIEF DESCRIPTION OF THE INVENTION This problem is solved by the features of claim 1. The subordinate claims relate to advantageous conditions. The inventive cleaning element comprises a carrier body to which elongated fringes are attached, the fringes enclosing a central region of the carrier body, a receptacle being associated with the central region in which a fastener is inserted, and a flat cleaning body being associated with the fastener. The fringes are attached around the central region of the carrier body. The fringes can be arranged in a ring. During use, the fringes extend laterally beneath the carrier body, ensuring that the flat cleaning element also makes contact with the floor being cleaned. Because the cleaning element is centrally positioned beneath the carrier body, high pressure can be applied. This, combined with the flat design of the cleaning element, results in particularly effective cleaning of stubborn dirt. The fringe can be attached to an annular fringe holder, with the fringe holder defining the receptacle and the holder being positively attached to the fringe holder, and the fringe holder being attached to the supporting body. The fringe holder has a number of housing elements for accommodating the fringe. The fringe, in turn, is preferably fixed securely to the fringe holder. This is preferably done by a physical or positive attachment. The attachment can be achieved, for example, by glue, tying, or a ML / a / zuzj / uu111 and sewn connection. The fastener is preferably retained in a positive connection within the receptacle. This allows for particularly simple and economical assembly. It is conceivable, in particular, that the fastener may be subsequently attached to a receptacle of an existing carrier body. The fastener and receptacle preferably form a snap-fit closure. Both the fringe holder and the bra are preferably attached by means of a snap closure to the wearer and the fringe holder, respectively. The fringe holder and / or the bra may be provided for this purpose with positive fastening elements, for example, in the form of protrusions, hooks, notches, or other similar features. The fringe holder and the fastener, together with the cleaning body and the fringe, can form a pre-assembled unit that is attached beneath the carrier body. In this particular context, it is conceivable that the fastener unit with the fringe and the fastener with the cleaning body could be marketed as a pre-assembled unit, so that the fringe and the cleaning body can be replaced at the end of their service life due to wear. It is conceivable here, in particular, that the fringe holder with the fringe and the holder with the cleaning body can be replaced separately. It is also conceivable that different holders with different cleaning bodies are provided, so that a cleaning body suitable for the cleaning task can be selected and attached to the fringe holder. Similarly, different fringe holders with different fringes can be provided, allowing the fringes suited to the cleaning task to be selected and attached to the cleaning element. The cleaning body can be attached to the fastener. The cleaning body is preferably fixed to the fastener. This can be achieved by physical bonding, for example, by adhesive or ultrasonic welding. Alternatively, the cleaning body can be attached to the fastener by means of a stitched connection. The cleaning body is preferably configured as a flat textile construction. The cleaning body may comprise microfibers. The cleaning body may also be equipped with harder fibers that act in an abrasive manner. In an advantageous configuration, the harder fibers and microfibers are arranged in zones within the cleaning body. The fringes can consist of a single component or several materials. The fringes may include, in particular, microfibers. The cleaning body can also include different fringes with varying properties. For example, harder fringes, softer fringes, fringes with microfibers, absorbent fringes, and abrasive fringes can be provided. The cleaning body, in an advantageous arrangement, comprises fringes of varying thicknesses. Thicker fringes can be arranged in one zone and thinner fringes in a second zone. It is also conceivable that fringes with different cleaning properties are arranged in different zones. Harder fringes, softer fringes, fringes with microfibers, absorbent fringes, and abrasive fringes can be arranged in different zones. The carrier body, fringe holder, and fastener are preferably made of a material suitable for injection molding. The fringe holder and fastener may be made, in particular, of polypropylene. The fringe holder with its attached housing can be removed from the carrier body and machine washed. This allows for thorough and separate cleaning of both the fringe and the cleaning body. In addition to improved cleaning, this also results in a longer lifespan. The bra may have a circumferential edge. Preferably, the outer circumferential edge features positive fastening elements that interlock with corresponding notches in the bra. This allows, among other things, the fringe bra and the bra to be disposed of separately. The holder may include a flat cap element, and the cleaning body is then attached to the cap element. The cleaning body is pushed flat through the cap element onto the floor to be cleaned, thus achieving a particularly good cleaning result. Thanks to the cap element, the holder also maintains its shape and stability. The cover element may have a circumferential edge that projects radially beyond the rim. This edge is preferably shaped so that it extends at least partially beyond the fringe holder. After the holder is mounted on the fringe holder, the edge then partially covers both the fringe holder and the fringe attached to it. This deflects the fringe attached to the fringe holder laterally, so that it projects outwards. The advantage of this is that the cleaning element becomes particularly bulky, and the cleaning body makes full contact with the floor being cleaned. Because the fringe projects outwards, it does not get caught between the cleaning body and the floor being cleaned. Ideally, at least one perforation is made in the lid. If the cleaning element is cleaned in a cleaning tray, the carrier body becomes immersed in the cleaning fluid. This fluid can then seep into the carrier body and, consequently, into the fastener. The perforation ensures that the fluid in the fastener can flow back through the cleaning body. A perforation can be made for this purpose in the center of the cap element. This allows, on the one hand, the liquid contained in the fastener to drain out and, on the other hand, also provides a particularly space-saving design, since the components of the support body can extend into the perforation of the cap element. According to another advantageous arrangement, at least one slit exists in a section of the corner region between the rim and the cap element. The inventive cleaning element, seen from above, preferably has a rotationally symmetric shape and is, in particular, capable of being centrifuged in a rotary centrifuge. For this purpose, the cleaning element is inserted into a basket-shaped receptacle that can be rotated. The cleaning fluid is expelled from the fringe due to the rotation. The rotation also has the effect of moving the fluid in the fastener toward the rim, where it flows out through the slit. The carrying body may have a recess for attaching a handle on the opposite side of the receptacle. The attachment may be configured as a hinged connection. This recess allows for better force distribution during cleaning. At least one second perforation may be found in the cavity, establishing a fluid connection between the cavity and the receptacle. Cleaning fluid that may accumulate in the cavity can flow through this perforation toward the fastener attached to the receptacle. The fluid can then exit again through the fastener via the perforations made there. BRIEF DESCRIPTION OF THE FIGURES Some modifications of the inventive cleaning element are explained below with reference to the figures. These show schematically in each case: Figure 1 a cleaning element seen from below; Figure 2 shows the cleaning element according to Figure 1 in a plan view. Figure 3 a fringe holder with fringe attached to it; Figure 4 A bra with cleaning body in plan view Figure 5 the fastener according to Figure 4 in a side view; Figure 6 a unit consisting of fringe fastener and fastener. DETAILED DESCRIPTION OF THE INVENTION Figures 1 and 2 show a cleaning element 1 comprising a carrier body 2 to which elongated fringes 3 are attached. The fringes are made of textile material and consist of multiple cords connected together like a rope. The fringes 3 are arranged here in such a way as to enclose a central region 4 of the carrier body 5. The central region 4 is in turn associated with a receptacle 6 with a fastener 7 inserted therein. A flat cleaning body 8 is arranged on the fastener 7. The cleaning body 8 completely covers the fastener 7. On the side of body 2 opposite receptacle 6 is a cavity 16 with a connection 17 for attaching a handle. The connection 17 is formed as an articulated joint. A second perforation 19 is made in cavity 16, establishing a fluid connection between cavity 16 and receptacle 6. The carrier body 2 has a triangular shape when viewed from above, and the fringes 3 project from the carrier body 2 essentially in a circular, radial direction. This design makes the cleaning element particularly suitable for being squeezed in a rotational centrifuge. Figure 1 shows the cleaning element 1 described above in a top view and Figure 2 shows the cleaning element 1 described above in a bottom view. Figure 3 shows in detail a fringe holder 20 with the fringes 3 attached to it. The fringe holder 20, with its wall facing the inner opening, defines the receptacle 6. The fringe holder 20 has attachment elements for the fringes that securely connect the fringes 3 to the fringe holder 20. The fringes 3 are passed through the attachment elements in a loop and knotted in sections. Figures 4 and 5 show the fastener 7 in detail. Figure 4 shows the fastener 7 in a top view, and Figure 5 shows it in a side view. The fastener 7 has a circumferential rim 9, as well as a flat cap element 10. The cap element 10 has a circumferential edge 11; ML / a / ZUZJ / UU 1 The edge 11 protrudes radially outward from the edge 9. The cleaning body 8 is fixed to the cover element 10 and covers the cover element on its entire surface. The cleaning body 8 is firmly connected to the cover element 10 by a stitched joint 18. The cleaning body 8 covers the cover element 10 on its entire surface on the side facing the floor to be cleaned. The cleaning body 8 consists of a flat textile material and may be provided with abrasive sections. The cleaning body 8 is firmly connected to the fastener 7. This is done in the present conditioning by means of a stitched joint 18. Several perforations 13 were made in the lid element 10. In addition, three slits were made in sections in the corner region 14 between the edge 9 and the lid element 10. Figure 6 shows a unit 21 consisting of a fringe holder 20 with fringes 3 attached to it, as well as a holder 7 with the cleaning body 8 attached to it. Both the fringe bra 20 and the bra 7 are made of a material suitable for injection molding, currently polypropylene. The fastener 7 is positively attached to the fringe fastener 20, the fastener 7 resting against the inner wall of the fringe fastener 20. The fastener 7 and, respectively, the fringe fastener 20 and the receptacle 6 form at least one snap closure. The fringe holder 20 is attached in a positive and interchangeable manner to the carrier body 2 by means of a snap fastener. This allows for the interchangeability of unit 21, which consists of the fringe holder 20 with the fringe 3 attached to it and the holder 7 with the cleaning body 8 attached to it. Unit 21 thus forms a pre-assembled unit.
