DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a collapsible mop pad holder which is collapsible from an operative cleaning position to inoperative positions in which the pad can be washed, pressed, attached and detached. The mop pad holder can also be operated as a conventional non-collapsible mop pad holder.
BACKGROUND OF THE INVENTION
1. Field of the Invention
It is known for such mop pad holders to comprise an intermediate section in which two opposite wing parts are pivotably attached, and latch means are operative to hold the wing parts in a substantially plane and aligned position when the holder is in its operative cleaning position. In the collapsed position, at least one of the wing parts will depend down from the intermediate section after release of locking means, and in this condition the mop can e.g. be washed and wringed in a mop wringer.
2. Description of the Prior Art
Collapsible mop pad holders of the type in question are disclosed for example in GB-A-2 206 037, EP-A2-461 684, WO 91/07129, WO 91/07130, WO 91/6849, DE-A-3 622 291 and EP-B1-175 019.
From the above and other references, it is known to provide collapsible mop pad holders which facilitate cleaning and wringing of at least part of the mop pad. The size of the part of the mop pad being wringed depends on the symmetry of the collapsed mop pad holder in the collapsed position. This symmetry depends on the way in which the mop pad holder collapses. It will be preferred that the mop pad holder collapses in a symmetrical way so that the whole of the mop pad may be inserted into e.g. a mop wringer for optimal wringing of the mop pad. This optimal wringing is facilitated in e.g. DE Published Patent Application No. 3 622 291, wherein the wing parts of the mop pad holder collapse symmetrically about two axes. However, as the collapsing of this mop pad holder is released by turning the handle of the mop pad holder, such collapsing may be accidentally released during use of the mop pad holder as this turning operation is typical in a working situation using a mop.
Furthermore, the collapsed position may be used for the attachment of the mop pad. However, a mop pad holder having both wing parts freely moving in relation to the intermediate section may be difficult to handle during attachment of the mop pad thereto. It will for this purpose be preferred that at least one of the wing parts is fixed in relation to the intermediate section to ease the attachment of the mop pad to the mop pad holder. In the prior art, this and the former problems have not both been satisfactorily solved in a single mop pad holder.
From the above and other references, it is further known to provide a separate mop pad holder and mop pad, which is fastened to the mop pad holder by means of e.g. snap fasteners, hook-and-loop fasteners (also known as Velcro.RTM.), fasteners foldable around the mop pad and snap locked, or the like. All these fasteners suffer from a severe drawback; they can for all practical use only be attached to the mop pad holder by the use of at least one hand, whereby the user will be exposed to the unhealthy cleaning fluids and dirt collected by the mop pads. A problem with the most easily operated fasteners is that these mop pads are likely to detach from the mop pad holders when collapsing the mop pad holder for cleaning and wringing the mop pad. Therefore, the use of mop pad holders prior to this invention gives unpleasant and unhealthy working situations for the user who will have to bend down each time a mop pad is to be attached or detached.
The provision of fasteners having corresponding fastening means attached to the mop pad often poses a problem when the mop pad is used or replaced as the size of the mop pad does not always fit the mop pad holder. The mop pad may be stretched after several periods of use or when used on a surface having a high friction, resulting in the mop pad not being in the appropriately stretched position relative to the mop pad holder-which gives an unsatisfactory operation of the mop. The mop pad may, on the other hand, s
