Detailed description

[0028] During the course of the following description like numbers and signs will be used to identify like elements according to the different views which illustrate the invention and its advantageous examples. In the figures some repetitive reference signs may have been omitted for clarity reasons.

[0029] In the figures 1A-4 is shown an example of a multi-function cleaning tool 10 (in the following "cleaning tool"), which cleaning tool 10 comprises a frame part 11. The frame part 11 is longitudinal and substantially rectangular in shape. The frame part 11 comprises on one longitudinally extending side bristles 17 and on other longitudinally extending side a squeegee 12. Both the bristles 17 and the squeegee 12 are releasably attached to the frame part 11 thus providing easy change for different types of the bristles 17 or the squeegee 12 for example due to wear or due to different type of cleaning need.

[0030] The frame part 11 comprises a head surface 19 to which a mounting part 16 is attached by a turning joint 15 and engagement elements 20 are attached.

[0031] In middle part of the head surface 19 of the frame part 11 the turning joint 15 for the mounting part 16 is located. Thus, the mounting part 16 for a handle arm (not shown) is mounted turnably by the turning joint 15 to the frame part 11. The turning joint 15 is configured to provide a turning movement R of the frame part 11 around its center by turning the frame par 11 around the turning joint 15 such that depending on need of cleaning either the longitudinal side of the bristles 17 is locatable against a floor or corresponding surface to be cleaned or the longitudinal side of the squeegee 12 is locatable against the floor or corresponding surface to be cleaned. Thus, the frame part 11 has a propeller-like movement R around its center.

[0032] The mounting part 16 is located on head surface 19 of the frame part 11 in an inclined position such that an angle A less than 90 degrees, advantageously less than 45 degrees, more advantageously 25 - 35 decrees, is formed between imaginary center axis of the mounting part 16 and the head surface 19 the frame part 11. Thus, the mounting part 16 is in inclined position in view of the surface level of the head surface 19 and thus, the mounting part 16 and the handle arm extend in inclined direction, not in perpendicular direction, from surface level of the head surface 19. The inclined positioning of the mounting part 16 provides for an advantageous positioning of the bristles 17 or the squeegee 12 against the floor or the corresponding surface to be cleaned in respect of ergonomics and of cleaning result.

[0033] The bristles 17 are attached to a support part 26, which in turn is attached to the frame part 11 releasably. Advantageously, the frame part 11 comprises a groove 27 or like for attachment of the support part 26.

[0034] The squeegee 12 is releasably attached to the frame part 11 by an attachment part 14 of the squeegee 12 located in an attachment groove 18 of the frame part 11. Advantageously, the attachment part 14 and the attachment groove 18 have from fitting forms, for example a dovetail fitting providing a releasable but reliable attachment of the squeegee 12 to the frame part 11. Advantageously, the attachment groove 18 has retaining protrusions 24, 25 at each outer edge of the attachment groove 18 for retaining the attachment part 14 of the squeegee 12 in the attachment groove. The attachment part 14 of the squeegee 12 is pressed into the attachment groove 18 to be located in the attachment groove 18. The squeegee 12 od released by pulling the attachment part 14 from the attachment groove 18 in longitudinal direction via one end of the attachment groove 18.

[0035] The frame part 11 also comprises on the head surface 19 of the frame part 11 two engagement parts 20 for attaching a cleaning cloth (not shown) to the frame part 11 of the cleaning tool 10. Each engagement part 20 comprises a longitudinal guide 21 located on the frame part 11 and a slide 22 configured to slide on the longitudinal guide 21 in a sliding direction S from first position to a second position towards center part of the frame part 11. The engagement part 20 also comprises an engagement element 23 for the cleaning cloth located on the slide 22. Advantageously, the movement of the slide 22 on the guide 21 from the first position to the second position in the sliding direction S is resisted by spring (not shown) and thus, movements of the engagement elements 23 from the second position to first position is spring assisted. Engagement holes of the cleaning cloth are to be located to the engagement elements 23 for attachment of the cleaning cloth to the frame part 11 of the cleaning tool 10. When the cleaning cloth is to be attached to the frame part the slide parts 22 of the engagement elements 20 are pressed towards each other providing a shorter distance in between of them and the spring resisting the movement. The engagement holes of the cleaning cloth are located on the engagement elements 23, when the engagement elements 23 are in the second position. As the cleaning cloth is in its place the engagement elements 23 are moved back to the first position and thus, the cleaning cloth tightens and is securely attached to the frame part 11 of the cleaning tool 10. The cleaning cloth can be located for cleaning with the side of the bristles 17 or the side of the squeegee 12 pressing the cleaning cloth against the floor or the corresponding surface to be cleaned.

[0036] Preferably, the engagement parts 20 correspond functionally to those described in the EP patent application 3569132 A1 of the applicant. The engagement parts 20 also advantageously correspond structurally to those described in the EP patent application 3569132 A1 of the applicant but are advantageously located on the top surface 19 of the frame part 11 instead of in grooves of the frame part 11.

[0037] The bristles 17 of the cleaning tool 10 can be of various types, known as such to one skilled in the art. The bristles 17 can thus be selected in view of the cleaning need.

[0038] The squeegee 12 of the cleaning tool 10 can be of various types, known as such to one skilled in the art. The squeegee 12 can thus be selected in view of the cleaning need. Advantageously, the squeegee 12 has a pointed cleaning edge for sharp line-shaped contact to the floor or corresponding surface to be cleaned. Additionally advantageously, the squeegee has outwards angled extensions 28, 29 of the squeegee 12 for extra contact to the floor or corresponding surface to be cleaned, when the handle arm is near to a horizontal position, for example in situations of cleaning under furniture.

[0039] Opposite surface to the head surface 19 of the frame part 11 of the cleaning tool 19 is advantageously planar and thus cleaning targets near walls or like is also easily reached.

[0040] The mounting part 16 has advantageously fastening means for fastening the handle arm releasably to the mounting part 16. The fastening means can be of the type known as such to one skilled in the art, for example threaded fastening means or quick fastening means or fitting fastening means.

[0041] In the description in the foregoing, although some functions and elements have been described with reference to certain features and examples, those functions and elements may be performable by other features and examples whether described or not. Although features have been described with reference to certain embodiments or examples, those features may also be present in other embodiments or examples whether described or not.

[0042] Above only some advantageous examples of the inventions have been described to which examples the invention is not to be narrowly limited and many modifications and alterations are possible within the invention.
