Description

The invention relates to a floor cleaning device according to the preamble of the claim 1.

Floor cleaning devices of this type, which come in a wide variety of designs with different made of textile materials, foams or similar floor cleaning elements may have been known for a long time.

In recent years, floor cleaning devices of this type have been increasingly used, in which the carrier plate is pivotable against one another and with one another Parts which can be locked in the parallel position have such that they are in the pivot position the parts can be used in the floor cleaning element and this in the locked Position the parts of the carrier plate tightly. For this are floor cleaning elements available on the bottom facing a variety of Have knobs, threads or strips of in particular textile material and both well suited for distributing moisture on the floor as well as for absorbing it are. These floor cleaning elements usually have side on the top Bags in which the parts of the base plate of the basic device in each other pivoted state can be easily plugged in and the locked state the parts of the carrier plate the floor cleaning element (the so-called "cover") safely hold the base unit.

When using these floor cleaning devices has proven to be a - especially professional Use - not negligible disadvantage highlighted that floor areas behind the heating pipes leading in the floor and the heating pipes themselves not can be cleaned sufficiently. Are floors in which such heating pipes lead, often processed in succession with appropriate floor cleaning equipment, form clearly behind these heating pipes and on the heating pipes themselves visible areas of pollution, which is not accepted by the clients.

It is possible to use separate cleaning elements at the appropriate points (Rags or similar) to do rework, but they are time consuming and exhausting.

DE 94 18 461 U1 discloses a floor cleaning device with a handle and a frame part attached to the handle made of a bent steel or aluminum wire. The frame part carries a removable floor cleaning element (cover) which is adapted in shape to the frame part. An elongated rectangular recess is provided on one of the sides of the frame part between two finger-like projections, which allows cleaning in the area of railing fastenings on steps. On the other side, the floor cleaning device is formed at an acute angle and is therefore well suited for cleaning surfaces that are restricted by an angle of less than 90 °, such as. B. on stairs in the curve area.

DE 84 00 739 U1 discloses a floor mopping device with a handle or handle attachment and a frame attached to the handle end for a removable, interchangeable mop cover that is adapted to the frame. The frame consists of two frame parts to be folded against one another about a pivot axis oriented approximately parallel to the bottom surface of the frame and to be locked in their inclined position with the aid of a locking device. One frame part has a T-shape and the other frame part has a U-shape which complements the T-shape of the first frame part to form an insignificant rectangular plate. The pivot axis is oriented approximately perpendicular to the longitudinal direction of the legs of the T or U shape. The locking device contains a magnetic lock. However, no recesses are provided on the side edges or the contour of this known floor mopping device.
