ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates generally to a wiping sheet adapted to be attached to a device used to clean house floors or walls.
As a convenient measure to clean a surface of house floor or the similar surfaces, it is well known to use a wiping sheet, for example, made of a nonwoven fabric adapted to be detachably attached to a cleaner device comprising a rectangular plate-like head and a stick pivotally mounted on a top surface of the plate-like head. The wiping sheet is put against a bottom surface of the plate-like head and front and rear or right and left marginal regions of the wiping sheet are folded back onto the top surface of the plate-like head so as to be fastened by clip means or the other fastening means provided on the top surface of the plate-like head.
The known wiping sheet has been available in various types, for example, those which are relatively thin, relatively thick, of relatively low rigidity and relatively high rigidity. The cleaner device, on the other hand, has generally been designed so that any one of these different sheets can be attached thereto. However, the means to fasten the wiping sheet has usually been of simple construction because it is essential to such cleaner device that the wiping sheet can be easily attached to the cleaner device. In consequence, it has been sometimes difficult for such conventional cleaner device to attach a wiping sheet of extremely high rigidity to the cleaner device even if it is possible to attach a relatively soft wiping sheet of relatively low rigidity to the cleaner device. Furthermore, the conventional cleaner devices has sometimes had a problem that a wiping sheet impregnated with plenty of oily agent is apt to slip and to be unintentionally detached from the cleaner device even after the wiping sheet has been held by clip means.
SUMMARY OF THE INVENTION
In view of the problems as have been described above, it is an object of the invention to provide an improved wiping sheet well-adapted for the various existing cleaner device.
According to the invention, there is provided a rectangular wiping sheet adapted to be attached to a rectangular plate-like head which is, in turn, combined with a stick mounted on a top surface of the plate-like head to form a cleaner device used to clean a surface of floor or the similar surfaces, wherein the wiping sheet is provided adjacent a pair of sides thereof extending in parallel to each other with a plurality of slits extending through a thickness of the wiping sheet and each of the slits has a length of 5~30 mm as measured in a direction along the pair of sides.
In a further embodiment of the invention, the slits are linearly formed.
In a further embodiment of the invention, the slits are formed in a generally V-shape.
In a further embodiment of the invention, the wiping sheet is made of a nonwoven fabric.
With the inventive wiping sheet formed with the slits, marginal regions of the wiping sheet can be easily and reliably head by crip means provided on a top surface of the plate-like head even when the wiping sheet is of a relatively high rigidity, since the marginal regions of the wiping sheet defined by the slits have their rigidity appropriately lowered. When the cleaner device employs anchoring projections instead of the clip means, these projections may be inserted into the slits to hold the wiping sheet.
Other and further objects, features and advantages of the invention will appear more fully from the following description.
