COMPLETE SPECIFICATION
"Improvements in or relating to cleaning means for surfaces immersed in liquid"
I/XKX RAYMOND LOUIS DONALD, a New Zealand Citizen of 22 Winsomere Crescent, Westmere, Auckland, New Zealand hereby declare the invention for which I / 5we pray that a patent may be granted to meA^, and the method by which it is to be performed, to be particularly described in and by the following statement:-
204770r
This invention relates to means for cleaning surfaces immersed in liquid, and in particular to means adapted to clean such surfaces as the underside of boat hulls, swimming pools, the inside of tanks containing in particular liquids, and other reservoirs or surfaces bounded by a liquid.
Existing methods of cleaning surfaces in contact with water or other liquids, particularly the bottom of boat hulls whilst the boat is floating in water, have not satisfactorily overcome the difficulty of keeping the cleaning means such as a brush head, in close or tight contact with the surface to be cleaned. Sane attempts to overcome this problem have been made by providing brushes with an elongated handle which can be forced against a boat hull by using an adjacent wharf or jetty as a fulcrum against which a handle bears. Such an arrangement is disadvantageous as it is clumsy to use. Also such a method cannot be used when cleaning a reservoir such as a swimming pool, for example. '
It is an object of the present invention to provide an improved and more easily operated means for cleaning surfaces bounded by a liquid such as boat hulls, swimming pools and the like, or which will at least provide the public with a useful choice.
Accordingly the invention consists in apparatus for cleaning a surface bounding a liquid comprising:
a cleaning means for movement over a surface to be cleaned in contacting engagement therewith;
a vane attached to said cleaning means adapted to generate a
2.0^-Hc fc hydrodynamic pressure on the vane when said vane is moved through the liquid by movement of the cleaning means over the surface to be cleaned to produce a resultant force sufficient to alone urge said cleaning means against the surface to be cleaned;
an elongated handle attached to said cleaning means for manipulation by an operator to move said cleaning means by hand over the surface to be cleaned;
a plurality of adjustable joints spaced along the length of said handle to facilitate adjustment of the longitudinal contour of the handle to the optimum shape desired for cleaning in conformance with the contour of the surface to be cleaned; and means operatively engaging said joints to rigidly retain said joints in any adjusted position.
To those skilled in the art to which the invention relates, many changes in construction and widely differing embodiments and applications of the invention will suggest themselves without departing from the scope of the invention as defined in the appended claims. The disclosures and the descriptions herein are purely illustrative and are not intended to be in any sense limiting.
One preferred form of the invention will now be described with reference to the accompanying drawings in which:
Figure 1 is a diagrammatic side elevation of a means for cleaning surfaces according to one preferred form of the invention;
Figure 2 is a front elevation of the apparatus of figure 1; ^re 3 is a representation of part of a handle and cleaning head connecting ijuse in the invention of figure 1;
*>4 770 ;Figure 1 is a diagrammatic representation of part of one preferred form of the handle for use in the means for cleaning surfaces of the present invention; ;Figure 5 is a diagrammatic side elevation of an alternative cleaning head for use in the invention; ;Figure 6 is a side elevation of a still further alternative cleaning head for use in the preferred form of the invention; ;Figure 7 is a side elevation of an alternative means to give rise to a force tending to move a cleaning means into contact with the surface to be cleaned in the preferred form of the invention; ;Referring to the drawings a means for cleaning surfaces particularly for cleaning surfaces bounded by liquid is provided as follows. A cleaning head such as brush or sponge 2 is provided which is engaged with or includes a mounting device for a handle. Of course multiple brushes or the like may be used. Thus the brush 2 may have bristles 3 extending from a plate 4 and the plate 4 may be engageable by a connecting piece 5 including a plate 6. The connection between the plates 4 and 5 may be ^n^any desired manner and, for example, threaded studs 7 may extend outwardly from the plate 4 so as to be engageable by nuts 8. This allows the cleaning head 2 to be removed, for example, to allow changing of the cleaning head in a simple manner. ;The connecting member 5 is desirably extended at 9 so as to be engageable by a handle 10. The handle 10 can be of any desired length depending on the surface to be cleaned and may ;204770 ;also include any desired number of joints or knuckles. In the construction shown in figure 1 the handle 10 comprises a first piece 11 and a second piece 12. The first piece 11 is engageable with the connecting member 5 and such engagement can be achieved, for example, by providing a transverse aperture 13 through the member 5 as seen, for example, in figures 3 to 7. An aperture 14 is provided in one end of the first handle piece ;11 and the apertures 13 and 14 may be surrounded by a sequence of radial ribs 15 which co-operate to position the first handle piece 11 at a desired or selected angle relative to the connecting member 5. ;The first handle piece 11 and the member 5 may then be engaged, for example, by passing a bolt through the apertures 13 and 14 fixed, for example, by a wing nut 16. ;The other end of the first handle piece 11 may be provided with an aperture 17 and radial ribs 18 so that a second handle ;12 may be engaged substantially in the same manner by providing apertures at each end such as apertures 19 and again co-operating radial ribs. By providing apertures 19 at each end of the handle 12 successive lengths of handle pieces may be engaged if desired. ;The connecting member 5 is also engaged by force directing means and in the preferred form of the invention the force directing means comprises a blade or vane 20 pivotally mounted on the connecting member 5. To achieve this the blade or vane 20 may have a bifurcated mounting member 21 mounted on the blade ;-5- ;204770 ;or vane 20 which engages a member 22 forming part of the connecting member 5 which member 22 lies in a plane substantially at right angles to the intended plane of cleaning of the cleaning apparatus. ;The member 22 may have an aperture 23 therein and the bifurcated member 21 has aligned apertures through which an axle 24 may be passed. ;It is desirable to restrict the range of rotation over which the vane or blade 20 may pass and this may be achieved by providing stops on the member 22. This is satisfactorily achieved by providing a pair of protrusions 25 positioned each side of the fixing point for the blade or vane 20. The shape and disposition of the protrusions 24 will be determined by the desired range through which the blade or vane 20 should pivot and a desirable range is about 40° in each direction from the position where the blade or vane 20 is substantially at right angles to the intended plane of cleaning. However a blade held at virtually any angle between 0° and 90° will produce some force in use substantially at right angles to the direction of motion, and could therefore be used. ;In the preferred form the vane or blade 20 is simply a flat sheet of material such as thin plywood or the like, however the same end could be obtained by having a blade or foil which is shaped substantially as a foil with a cross section which creates a lift on movement through the water or other liquid, the lift being directed towards the surface to be cleaned. Such a foil could be rigidly fixed to a cleaning"head 2 rather than ;6 ;204770 ;being pivotally mounted as described to this point, so that upon movement in one direction the foil creates lift directed towards the surface to be cleaned and upon movement in the opposite direction, creates lift away from the surface to be cleaned. ;In the construction of figure 5 the brush 2 is replaced by a scraper 30 which may be held in a mounting block 31 affixed to the connecting device 5, for example, by screw bolts or other fixing members 32. ;In the construction of figure 6, the brush 2 is replaced by a bearer for abrasive material prepherably in strip form. The bearer comprises, for example, a support having an outer part 33 and an inner part 34 engageable one with the other, for example, by protruding threaded studs from the part 33 extending through apertures in the part 34 to be fixed by a fixing device such as wing nuts 35. Thus, for example, abrasive paper may be clamped at the ends between the parts 33 and 34 so as to provide an outer cleaning face 36 for the abrasive paper 37. The inner bearer member 34 may be positioned on a mounting block 38 engageable with the connecting device 5. ;In figure 7 a construction is shown wherein the blade or foil 20 is replaced by a pair of blades 40 mounted on a bifurcated support 41 engageable with the connecting member 5. Multiple blades can be used and can be fixed directly to the bearer or connecting member 5 or may be mounted through an intermediate member such as shown in figure 7. ;Whichever embodiment or application is selected the operative end or head of the apparatus may be provided with ;7 ;buoyancy means to assist with the handling of the apparatus particularly where long operating handles are used. This buoyancy means could comprise a piece of polystyrene attached to connecting means 5 or could be provided by some other, ;equivalent material or component. ;The use of the invention is as follows: ;In the embodiments shown in figures 1 to 7» the knuckles in the handle are set so that the cleaning head 2 will be in contact with the surface to be cleaned at least over a substantial length of the travel in operation. In particular it is desirable that the brush head be substantially squarely in contact with the surface to be cleaned. The arrangement of figure 1 is set up to indicate a possible arrangement for cleaning a boat hull by a person standing on an adjacent jetty, wharf, marina, dinghy or the like. Clearly other dispositions will be required, for example, for cleaning the walls of a swimming pool which are substantially vertical or cleaning the bottom of a swimming pool which is substantially horizontal. ;By suitably directed pressure on the handle 10 the cleaning head 2 and the vaneor blade 20 will be moved through the liquid such as water creating a force which will push the vane or blade 20 to a position against one of the stops 25. This will give rise to hydrodynamic pressure in the form of a force which is directed so as to bring the cleaning head 2 into contact with the surface to be cleaned. Movement in the opposite direction will cause the vane or blade 20 to move against the other stop 25 again giving rise to a force tending to keep the cleaning ;-8- ;204770 ;head 2 in contact with the surface to be cleaned. Alternative movements of this type will in each case substantially retain contact between the cleaning head 2 and the surface to be cleaned. ;Thus it can be seen that at least in the preferred form of the invention apparatus is provided which may easily and effectively clean surfaces bounded by a liquid such as water, for example, boat hulls, swimming pools or other reservoirs. The apparatus gives rise to forces which will keep the cleaning head substantially in contact with the surface to be cleaned which increases the speed and efficiency of the cleaning of such surfaces. ;-9- *
