DESCRIPTION:
BRIEF SUMMARY
SCOPE OF INVENTION
This invention relates to a device for the cleaning of level surfaces.
PRIOR ART
For cleaning premises and the like, so-called cleaning mops are used for professional purposes. These consist of a mop frame which often has the appearance of a flat, profiled, elongated plate, a flexibly attached handle on the upper side of the frame and a mop in the form of various types of textile cloth, varying according to the area of application, detachably fitted to the underside of the frame. The handles are often articulated so that they can be rotated in directions forming a hemisphere. The underside of the mop frame is often provided with grooves, into which plastic bars, to which Velcro strips are affixed, are inserted. The Velcro strip has the function of keeping the mops fixed in position during use so effectively that they remain attached to the mop frame even when this is lifted and shaken, but can be removed relatively easily when the mop needs to be changed.
The mop frames which are available on the market function satisfactorily for a great many cleaning operations, but have a number of disadvantages. In order to make the Velcro strips replaceable, they are affixed to a bar which is pushed into grooves on the underside of the frame. This means that the Velcro barbs lie essentially in the same plane as the underside of the frame and thus provide a very poor grip, which in turn means that the Velcro strip has to be relatively wide in order to function adequately. Another disadvantage of this design is that the wide Velcro strips and the affixing of these to the bars are relatively expensive, and also that the groove on the underside for holding the bars is a place for the accumulation of dirt and the like.
The flexibility of the link between the frame and the handle is an advantage in most cleaning operations as it permits good movability of the mop when cleaning floors. For the cleaning of walls and ceilings, however, this flexibility is a disadvantage as the frame cannot then be properly controlled.
For the cleaning of large surfaces use is made either of a mop frame of normal width, generally 55 cm, which makes the work time-consuming, or of an extra-wide mop frame. These wide mop frames are however too clumsy to be used for normal surfaces, which means that the cleaner has to have several different mop frames available for different areas.
BRIEF ACCOUNT OF THE INVENTION
The aim of the present invention is to overcome the above problems. According to one aspect of the invention, this is achieved with a mop frame for cleaning equipment comprising an elongated plate, provided with a flexible handle fastener on the upper side, and characterized in that at least the underside of the frame is provided with attachment means for the attachment of holder bars, to the underside of which Velcro strip is affixed. This design results in the presence of replaceable Velcro strips on the frame, affixed to surfaces which are essentially in the same plane as the underside of the frame. In addition, the holder bars form part of the width of the frame.
According to another aspect of this invention, it offers a mop frame for cleaning equipment comprising a plate provided on the upper side with a handle fastener which is situated in the middle of the mop frame and which comprises a first component joined to the plate via a first hinge, the axis of rotation of which is parallel with the longitudinal direction of the plate, and a second component which is joined to the first component via a second hinge, the axis of rotation of which is perpendicular to the first axis of rotation, which is characterized in that the handle fastener is provided with a locking device capable of locking the second hinge so that the handle can only move by means of the first hinge.
According to another aspect of this invention, it offers a surface cleaning device comprising two mop frames, each provided with a handle fastener, which device is characterized in that the connecting element is detachably connectable to the handle
