Definitions

  • the outer layer of the cleaning pad has an open structure such as woven, fibre or foam.
  • the movement of the gripping members between said first and second positions is, or includes, a snap action.
  • a snap action causes the gripping members to move apart quickly while retaining contact with the same respective portions of the cleaning pad thereby stretching the same and causing the additional tension and hence retention of the cleaning pad.
  • a second advantage is that when moving the gripping members from the second to the first position, to remove the cleaning pad, the snap action acts as an ejection force on the cleaning pad so that the cleaning pad is totally removed from the gripping members and can therefore be discarded at the appropriate location as the snap action effectively acts to "pop" the cleaning pad from the gripping means .
  • the gripping members are of elongate form and are relatively straight, with the gripping members in each set provided in a linear spaced array and can be provided in a series of rows .
  • the gripping members can be angularly aligned so as to approach the cleaning pad at an angle which may be perpendicular to the cleaning pad or angled outwardly therefrom.
  • some or all of the gripping members can be provided with hook formations if that is found to increase the gripping action of the cleaning pad.
  • the number, spacing and/or formation of the gripping members can be varied dependent on the particular formation of the cleaning pad with which the same are to be used.
  • the gripping means is provided for use in conjunction with a handle, said handle located with the gripping means and, typically, depending away from a face of the gripping means which opposes the face from which the gripping members protrude.
  • the movement of the gripping members between the first and second positions is achieved by relative movement of the handle and gripping means.
  • movement of the handle towards the gripping means causes movement of the gripping members from the first to the second position and movement of the handle away from the gripping means causes movement of the gripping means from the second to the first position.
  • the gripping means can be angularly adjustable with respect to the handle to allow the cleaning operations to be performed and then further pivotal movement to one of the extremes of movement between the handle and gripping means allows, the handle with the gripping means held by or against an item, to be moved relative to and with respect to the gripping means, towards the same to contact and grip the cleaning pad, or away from the gripping means to cause the ejection of the cleaning pad.
  • the gripping members are provided as part of a plate, said plate retained on the gripping means such that movement between the first and second positions involves movement about an overcentre so as to provide the required snap action.
  • the handle is removably attachable to the gripping means, via engagement means which can be moved between engagement and open positions.
  • the movement of the engagement means is achieved by operation of a lever which is provided as part of the handle and which, in one preferred embodiment, has an actuation means at, or adjacent to, the location at which the handle would be held, thereby allowing the actuation of the engagement means by the user when holding the handle in a normal position so as to allow the release of the gripping means from the handle if, for example, the same become unclean or damaged, and replacement with a new gripping means.
  • a handle and gripping means assembly which can be operated by a user with their hand on the handle and so the engagement and removal of cleaning pads from the assembly can be achieved without the need for the user to physically contact the cleaning pad thereby greatly improving hygiene.
  • the gripping means can also be removed from the handle for replacement purposes without the need for physical contact with the gripping means by the user which again provides a hygiene improvement.
  • the cleaning pad is also effectively and reliably gripped by the gripping means during use.
  • the cleaning pads can be held in a magazine in the form of a holder, said holder also acting to locate, for storage purposes, and in one embodiment gripping purposes, the handle and gripping means .
  • the holder can also be used to allow the orientation of the gripping means as they approach a cleaning pad in the holder to be correct so as to ensure that the gripping means exert the gripping force on the cleaning pad and lift the same from the holder for use.
  • the holder has two positions for storing the handle - (a) in the ready to use position on top of the stack of pads, and (b) seated at the rear of the holder facing the opposite direction (to provide a means of avoiding any "drip " contamination of fresh pads) with the grip located over a protrusion that ensures the grip remains in the open position ready for use.
  • a plurality of features and any or any combination of the same improve the usability of the system and in particular the ease of storing the handle and the loading of fresh pads.
  • These features include a rotating grip of the handle which includes a stop that ensures the open grip does not rotate under the weight of the handle in the stored position in the stand, or under applied pressure by the user when engaging a pad. The grip holds the handle on the pad.
  • the holder includes one or more ribs located on the inside walls of the storage area for the pads to provide limited frictional resistance with the vertical stack of pads located within, so as to provide a "de-nesting" feature to ensure pads are dispensed singularly when pulled out by the handle.
  • ribs are made from a semi flexible material, or feature a spring loaded seating that enables the ribs to deform/move to allow a carton in which the pads are provided to be loaded into the holder such as in a perpendicular direction to the ribs .
  • the teeth of the gripping means return to a third position.
  • the teeth return substantially to this position at which the teeth are held in the best position for gripping the next cleaning pad.
  • the teeth move from the third to the first gripping position in a snap action.
  • the handle and gripping means are connected via a pivot location and said gripping means is selectively removable from the handle by pivoting the gripping means to a position at an extremity of the range of pivotal movement.
  • the position for removal is outwith the normal movement range required for operation of the apparatus in the cleaning operation.
  • the present invention provides apparatus which allows for the self contained attachment and ejection of the cleaning pad from the assembly without the need for the same to be located in the handle and therefore allows greater ease of replacement.
  • a cleaning pad for use in a cleaning action, said pad formed from a blend of fibres including cellulosic fibre.
  • the cellulosic fibre is included within the range 20-70% of the fibre blend and preferably is viscose > 8 decitex fibre titre. In one embodiment the other fibre is provided within the range 30-80%.
  • the other fibre typically includes 30-80% wool fibre (keratin) . Yet further preferably the other fibre includes, 30-80% sheep's wool > 30 micron.
  • the combination of material used to form the cleaning pad is 60-70% sheeps wool and 30-40% viscose.
  • the pad composition includes an added semi-soluble fibre such as 90%+ hydrolised PVOH.
  • the added fibre is a bi-component fibre comprising an insoluble coating (e.g. aliphatic polyester) and a semi-soluble core (e.g. PVOH) . This fibre may comprise 5-100% of the total fibre weight.
  • the material may include abrasive particles and/or a polymer coating and/or a releasing agent such as silicon which allows the material to be cut effectively.
  • the blend of fibres optimises the combination of cleaning pad properties including specific gravity to assist flushing, dimensional resistance when wet which improves the feel and control of the pad when in use, absorbance which assists the cleaning operation of the pad and limits the wet strength of the cleaning pad. This, in turn enables the at least partial disintegration of the pad and hence allows the improved disposal of the same through flushing or other disposal means.
  • a cleaning pad to which an aqueous dispersion of a polymer binder is applied.
  • the cleaning pad has a penetration of said binder from at least one external surface inwardly to a depth of up to 3mm. In one embodiment the depth of penetration is up to 2mm.
  • the binder is applied to opposing planer external surface of the pad.
  • the selective application of the binder results in a cleaning pad having, from one external surface, a relatively strong layer, an inner core or layer of unbonded fibre and at the opposing side another relatively strong layer.
  • the said strong layers include the polymer binder.
  • the fibres of the cleaning pad are needled at a ratio of between 2-4 penetrations per cm. square.
  • a proportion of the fibres in the cleaning pad are cut typically when part of the cleaning pad. In one embodiment more than 60% of the fibre within the pad has a length of less than 15mm.
  • the layout of the perforation/cut lines in the pad is a grid of parallel cuts and joining tags of uncut material, across the length and width of the pad.
  • one set of cut lines in one direction are offset to perpendicular to create a " stretcher bond" pattern.
  • additional layer cut lines are provided to segment the pad and promote quicker partial break-up of the pad after flushing, as well as weaker lines of folding to assist with flushing.
  • the layout of perforations in the pad is to ensure there is a maximum spacing between cut lines of 15mm in any direction and more preferably less than 10mm in at least one direction.
  • the pad perforations have material connection points wider/greater in dimension and/or frequency, along the length of the pad and narrower and/or less frequent across the pad width in the perpendicular plane. This provides the necessary minimum strength to resist the stretching load exerted by the grip during engagement, but provides a weaker bond between the rows of perforations across the width, which are held in place during cleaning by the grip teeth. This promotes the break-up of the pad after flushing, without compromising integrity in use.
  • the polymer binder is biodegradable.
  • the polymer is a high molecular aliphatic polyester polyurethane.
  • the binder applied to the pad is a water- resistant binder coat applied to one side, and is preferably a biodegradable, high molecular weight, aliphatic polyester.
  • a semi-soluble polymer coating is applied such as Poly Vinyl alcohol (PVOH) or Starch.
  • the density of the cleaning pad is within the range of 1.05 - 1.45 x the density of the water or water solution in the toilet bowl trap prior to flushing. This is particularly relevant when the pad is impregnated with soluble solids such as surfactants, dye etc, that may significantly increase the density of the flush water solution.

  • Figures 12a-c illustrate embodiments of the cleaning pad in plan
  • Figures 13a-h illustrate positions of the handle with respect to the holder
  • Figures 14a-c illustrate further features of the holder.
  • the gripping means includes a body 2 which has a first side 4 and a second, opposing side 6, from which gripping members 8 protrude to allow the selective gripping of a cleaning pad.
  • this includes, in this embodiment, an aperture 10 and a location bar 12 which is provided for location with the end of a handle in a manner described subsequently.
  • the bar is mounted with respect to the gripping means so as to be movable as indicated by the arrow 14 through the aperture 10. The purpose of this movement will also be described subsequently.
  • FIG. 6 there are shown two sets of gripping members 10, set 16 and set 18.
  • each set there is provided a plurality of gripping members 10 which, in this arrangement, are linearly spaced as shown.
  • the gripping members are shown in a first position.
  • Figure I b in broken lines, are the position of the gripping members 10' when in the second position, having been moved there by movement in the direction of arrows 20,22 respectively.
  • Figures 2a-b illustrate how the gripping members 10 are provided as part of a plate 24 which, in turn, is connected to arms 26 which in turn is connected to rod 12.
  • the plate 24 is held in the gripping means body 28 via the connection of the bars 30 in the hook formations 32 in a manner which allows pivotal movement 25 and hence allows the movement of the gripping members with the snap action.
  • the plate is held in tension such that it is moved from the rest position of Figure 2a to the tensioned in use position as indicated by arrows 27.
  • relative movement is required between the plate 24 and the body 28.
  • this is achieved by placing the gripping means such that the gripping members 10 contact the surface 34 of the cleaning pad 36 as shown in Figure Ib in bold lines and then applying a force to either of the gripping means or handle such as to push the same together which causes the gripping means plate to move to the second position and hence the gripping members, which retain contact with the pad, to move to the second position 10' in which, in this embodiment, the gripping means are extended as shown in Figure Ib and the cleaning pad is held under tension by stretching as indicated by the broken lines 36'.
  • the reverse steps are followed in the handle and gripping means are moved apart to cause the gripping means plate to move from the second to the first position and the plate moves with the snap action, as the grip of the gripping members is released, to eject the cleaning pad.
  • force is applied via the handle 38 as shown in Figures 3a-c which is formed so as to engage with the rod 12 on the gripping means.
  • the handle can be permanently attached to the gripping means but alternatively, and preferably, the gripping means is releasable from the handle.
  • the release is by the opening of engagement means 40 which include an engaging collar which is at one end of the handle 38.
  • the opening of the collar is achieved via a lever 42 which is shown in the open position in Figure I c and which has an actuation point 44 adjacent to the position 46 for the user's hand on the handle.
  • the collar 40 is normally held in a closed position in engagement around the rod 12 of the gripping means, thereby holding the gripping means in conjunction with the handle.
  • the engagement means 40 can also be used to allow other implements to be picked up and used in conjunction with the handle, with the other implements having a rod attachment means around which the collar fits and including any or any combination of a brush or any replaceable cleaning means .
  • the cleaning apparatus in accordance with the invention is formed and can be used for the cleaning operation which is required. After one or a number of uses, it will be desired to discard the cleaning pad and replace the same with a new, clean version.
  • the gripping means and handle are moved apart to a limited extent which causes the gripping plate 24 to which the rod 12 is connected to be moved and the gripping members to move from the second, gripping position 10', to the first position 10 in which the pad is released from the grip .
  • the movement from the second to the first position also has a snap action such that in addition to causing the gripping members to be released from the pad, the snap action causes the positive ejection of the cleaning pad from the gripping means .
  • Figures 4a and b illustrate an arrangement of gripping means, handle 38, and holder 48. If required, a store of cleaning pads can be held in the holder and the holder is provided with guides to allow the guided movement of the gripping member on the handle to grip and remove one of the cleaning pads for use.
  • FIGS 5a and b there is illustrated a further embodiment of the invention.
  • the gripping members 110 are held in a plate 124 such that initially, as indicated in Figure 5a, only some of the gripping members will contact the cleaning pad 136 as the handle 138 and gripping means 102 are moved to contact the pad. This is the first position. Thereafter continued movement causes all of the gripping members 1 10' to contact the pad 136 as shown in Figure 5b as the pivot location points 130,132 move as indicated by arrows 125 to the second position shown in Figure 5b and in which the cleaning pad is gripped.
  • the plate 124 can be an integral part of the gripping member 102 housing 128 or formed separately. To remove the cleaning pad the reverse of the steps are performed.
  • a cleaning pad 302 in accordance with the invention which includes front and rear opposing planar surfaces 304, 306.
  • layers 308, 310 respectively which include a polymer binder material.
  • a layer 312 which preferably does not include the polymer binder.
  • a blend of fibre is used in the cleaning pads construction to optimise the desired combination of cleaning pad properties : specific gravity (to assist flushing), dimensional resilience when wet (feel and control of pad in use), absorbency (to assist cleaning) and limit wet strength (to enable partial disintegration of pad) .
  • the preferred blend is 20-70% cellulosic fibre, 40-80% other fibre, more preferably 20-70% Viscose rayon, > 8 decitex fibre titre, 30-80% sheep's wool >30 micron.
  • the application of the aqueous dispersion of polymer binder is controlled to ensure that the penetration of cured polymer, after manufacture, is substantially limited to the first 2mm inwardly from both the external surfaces of the pad.
  • the result is a cleaning pad with three distinct layers — relatively strong outer layers and an inner core of lightly entangled unbonded fibre. This subsequently enables partial break-up of the pad structure by de-lamination after flushing.
  • the required de-lamination effect described above can be further improved by minimizing the mechanical entanglement of fibre during the needle punching part of the manufacturing process .
  • the preferred rate of "needling" is between 2-4 penetrations per cm sq.
  • Post flushing de-lamination of the pad can be enhanced further still, by increasing the density of cut lines through the pad structure, thereby reducing the number of long uncut fibres within the pad structure.
  • Preferably, more than 60% of the fibre within the finished pad will have a cut length of less than 15mm.
  • FIGs 8a-g and Figures 9a-b illustrate an end of the assembly handle 314 and gripping means 316.
  • the gripping means 16 are provided with teeth for gripping the cleaning pad 302 in a manner which will subsequently be described.
  • the gripping means 316 may need to be detached from the handle to allow replacement and this is achieved by manipulation of the pivot location 318 between the same.
  • the pivot location is formed by an axle rod 320 located in jaws 322 of the handle. In normal operation of the device, pivotal movement between the handle and gripping means is possible to allow the normal pivotal movement of the cleaning pad in the cleaning operation.
  • a thumb activated switch 412 located at the tip 402 of the handle 404 are two plungers 406, 408 which are connected by a flexible strap 410 (which is supported in the handle) to a thumb activated switch 412 at the end held by the user.
  • the thumb switch pushes the plungers out from within their housing, against the top of the gripping assembly frame 414 to activate the ejection movement within.
  • the plungers then automatically retract into the housing of the handle by means of a compression spring 415 arrangement.
  • This design provides a convenient means of remote ejection of the used cleaning pad, without a fixed link between the thumb switch and gripping assembly. This has the benefit of allowing easy replacement of the gripping assembly, and providing unrestricted movement of the gripping means assembly in use.
  • Figures 13a-14c illustrate a further aspect of the invention and show a holder 600 and handle 602 located therein.
  • the handle will operate in a similar manner to that as previously described.
  • the Figures 13a — d illustrate the handle in a first in use position on top of a stack of cleaning pad held in the holder and Figure 13e-h illustrate the handle in a second storage position in which drips from the handle are prevented from landing on the pads as the handle end and gripping means do not lie above the pads in this position.
  • a gripping means for a cleaning pad which allow the effective and reliable gripping of the pad while at the same time allowing the grip to be achieved by the user remotely of the pad itself. While in certain embodiments the ejection of the pad can be achieved by the reverse steps of the gripping step, it should be appreciated that other actuation means can be provided in the handle and/or gripping means to cause the ejection of the cleaning pad.
