Description

The present invention relates to cleaning implements. Especially the invention relates to a mop frame and to a mop. In particular the invention relates to a mop frame according to the preamble of claim 1.
From prior art various solutions to attach mops to mop frames are known. Of course, the basic intention is that the attachment be relatively firm and quick, and possible to carry out without touching by hand.
A common type of mop frame is such that the mop is attached on the bottom side i.e. in use towards the floor facing side of the planar plate by different types of fixing means such as loops, Velcro fastening means or pockets located at each end of the mop, into which pockets are then slid each end of the plate. A handle arm is typically fixed at the middle part of the plate of the mop frame on upper side of the plate. Typically the mop frame is provided with pivoting means in the middle of the plate and with means for pressing the longitudinal halves of the plate of the mop frame towards each other in order to remove and/ or place the mop onto the plate. One disadvantage with in these types of mop frames is that longitudinal distance changes and thus the attaching and removing of the mop without touching with hands is not possible. The attaching and removing the mop to and from the mop frame is also cumbersome and time consuming.
A solution known from prior art is type comprising a pocket or a loop at one end of the mop receiving one end of the plate of the mop frame, the plate being pushed into the pocket or through the loop by sliding it from the side, whereby the mop can be kept in place, for example, by pushing it against the floor by foot. In the known solutions, the other end of the mop is held, e.g., by means of a piece of Velcro, a flexible loop or a tongue provided with a press fastener. The Velcro fastening has the disadvantage that its holding power weakens depending on the times of use. In repeated use, the above-mentioned flexible loop or the tongue provided with a press fastener may be a more durable solution, but their weaknesses: slowness of setting the mop in place to some extent and also the fact that they are difficult to attach and remove without touching by hand.
Attachment solutions, which are based on a magnetizing force, are disclosed in publications US 4658461 and DE 19940436 , for example. In said US publication, a magnetic rod is provided at the upper part of the mop frame, cooperating with a metal plate that constitutes the upper surface of the mop. In the DE publication, in turn, the upper surface of the mop is provided with a raster that is made of a mixture of metal powder attached to the surface of the mop by a suitable means, such as gluing or spraying.
In publication WO 2007/085686 is disclosed a mop frame comprising a handle, a plate connected to the handle and a mop detachably attached to the plate, at least one pair of holding members, consisting of a permanent magnet and a cooperating counterpart, being arranged for holding the mop onto the plate, whereby the magnet and the counterpart are essentially planar at the surfaces that come towards each other and they are attached to the plate and to the mop, respectively, so that they face each other in the operating position of the mop, in which the essentially flat magnet or counterpart on the mop is attached to the mop under a fabric that constitutes the upper surface of the mop.
In publication DE 102006027284 is disclosed a mop frame in which an example is described, which has a plate for attaching a cleaning cloth and to which plate a handle arm is attached in the middle part of a pivotably to one end of the plate attached top plate. In this example the top plate extends over the length of the plate.
In publication FR 2663832 is disclosed a mop of a mop frame intended to be detachably attached to a mop frame, wherein the mop comprises one pocket at one end of the mop on the top side of the mop into which pocket is to be placed the open end of the corresponding mop frame.
In publication WO 2004086931 is disclosed a floor mop capable of using both sides, wherein the floor mop comprises: a supporting pad on which velcro tapes are attached so that each floor cloth is attached on both surfaces, and having a rectangular planar structure; a rotation section having a first rotation zone of which a lower part is hinge-combined at side portion of the supporting pad for being capable of rotating; a second rotation zone which a rotation incision portion is formed at a central part of an upper part thereof and is incised therein toward the direction of the length, and which a lower part thereof is hinge-combined at an upper part of the first rotation zone for being capable of rotating.
One disadvantage of mop frames according to prior art is that the attaching and removing of the mop without touching with hands is not possible and thus the attaching and removing the mop to and from the mop frame is also cumbersome and time consuming. Another disadvantage of mop frames according to prior art is that when lifted in an open position the mop frame is unbalanced thus making handling of the mop frame cumbersome and also the attaching and removing the mop to and from the mop frame difficult.
An object of the present invention is to create a mop frame and a mop in which the problems and disadvantages of the devices known from the prior art are eliminated or at least minimized.
An object of the present invention is to create a mop frame and a mop, in which the disadvantages of solutions known from prior art relating to attaching and removing the mop to and from the mop frame are solved.
