ABSTRACT:
This invention relates generally to treatment of surfaces, such as cleaning surfaces; and more particularly, to improvements in mops, mop retention, and mounting, apparatus for scrubbing and mopping of surfaces by force application, as via an elongated handle; and surface treatment methods, including substantially simultaneous application to such surfaces of pesticide and traction treatment materials, as for example prior to or subsequent to surface cleaning.
Many surfaces to be cleaned contain interstices, cracks or crevices, in which dirt particles become embedded or otherwise build up. Examples are cracks between tiles forming tiled surfaces, cracks and crevices in marble, clay, concrete, or synthetic material flooring, and surface interstices in many different types of floors. It is extremely difficult to remove such embedded or built up dirt particles using conventional mopping apparatus and/or procedure. It becomes necessary to scrub such surfaces, using a brush or brushes having bristles that can reach and remove the embedded soil or dirt particles.
In the past, it was known to provide for scrubbing and mopping of floor surfaces, using elongated handled equipment; however, such equipment lacked the unusually advantageous improvements in structure, functions and results, as are now enabled and produced by the present invention, and meeting needs for improved and more effective use and operation, as will appear.
SUMMARY OF THE INVENTION
It is a major object of the invention to provide improved apparatus and methods meeting the above needs. Basically, the improved mop aspect of the invention concerns a mop, as is easily and readily applied to a carrier, and is easily and readily removable from the carrier as for replacement. The mop comprises:
a) a laterally extending head band, and mopping strands extending generally longitudinally from the head band, and
b) two grommets attached to the head band to define through openings for passing fasteners that attach the mop to the carrier.
As will appear, the head band may typically have lateral length
11
, and a medial region, the grommets being spaced apart from the medial region at a spacing l
2
, and where l
2
is substantially less than l
1
. Further, the grommets are typically, equally spaced from the lateral ends of the head band for balanced attachment of the mop to the carrier, as by fasteners which are spaced at equal distances from the center of the carrier.
Another object is to provide a mop with grommets, as referred to, to be attached to a carrier block, which also carries scrubbing means presented downwardly toward a surface to be scrubbed, the mop, attached via the two grommets to a forward surface of the carrier, whereby the mopping strands extend forwardly longitudinally beyond the scrubbing means, thereby enabling ready mopping and scrubbing simultaneously of a surface to be cleaned.
It is another object of the invention to provide improved apparatus for scrubbing a surface, and comprising, in combination:
a) a supporting carrier, including a block and scrubbing means carried by the carrier, to project toward the surface for scrubbing that surface,
b) first means for attaching an elongated handle to the carrier to extend in a first direction from the carrier,
c) and structure for attaching a mop to the carrier with mop strands extending in generally parallel relation with that surface and in mopping contact therewith as the scrubbing means simultaneously engages that surface, for simultaneous mopping and scrubbing of that surface, as the handle extends at an angle to the surface to displace the carrier, scrubbing means and mop parallel to the floor surface,
d) and including the mop having a head band attached to the carrier at a first side of the carrier, there being at least two grommets attached to the head band to define through openings for passing fasteners that attach the mop to the carrier.
As referred to, the fasteners typically and advantageously pass through the grommet openings and into the carrier block, at locations equally spaced from the center of the block, such spacings together being less than the overall width of the block, to provide advantages, as will appear.
An additional object is to provide a carrier that has first and second parts which are relatively movable longitudinally, the scrubbing means carried by at least one of the parts, the parts relatively adjustably movable longitudinally to clamp the mop head.
Another object is to provide structure associated by the carrier and having teeth presented toward and gripping engaging the head band, at lateral sides of the grommets.
A further object is to provide structure that includes an adjustable clamp for adjustably clamping the mop head, and having a first position in which the mop head is removable from attachment to the carrier, and a second position in which the mop head is attached to the carrier. The clamp typically has a part with adjustable screw thread fastener attachment to the carrier. An additional object includes the provision of scrubbing means on the carrier block, which is either bristles or in the form of a scrubbing pad, these elements located rearwardly of the mopping grommets. The bristles may include rows of bristles, with the bristles of one row having lengths greater than bristles in other rows, one row extending parallel to the mop head.
A yet further object is to provide an improved mop having a head band that extends in a lateral direction, and fastener supports providing openings through the head band, the supports being laterally spaced apart, so that a plane which extends in a longitudinal direction substantially normal to the head band and bisecting the spacing between the fastener supports also substantially bisects the mop.
An additional object is to provide a surface treatment method, which includes:
a) applying a flowable pesticide material to the surface, as for example to corners and crevices of a room,
b) and applying a flowable surface restorative or traction material to the surface, as for example a walkway, such applications being location and timewise related, as for example, to contiguous surfaces in a room, and the applications effected during the same work period.
Selected portions or excess portions of the applied materials may be removed by providing and passing at least one mop over and in contact with the flowable material or materials on the surface or surfaces..
These and other objects and advantages of the invention, as well as the details of an illustrative embodiment, will be more fully understood from the following specification and drawings, in which:
