Definitions
- the present invention concerns the technical sector relative to the production of accessories for washing floors.
- it concerns the technical sector relative to the production of accessories to wring clothes for washing floors, specifically clothes made of a series of strings, used by many producers, among them "Vileda”.
- the type of cloth mainly used nowadays is the one having the above-mentioned shape, also called "mop", comprising a series of cloth strings of definite length, of variable thickness, largeness and absorption of liquids, free on one side and contained on the opposite side by a final support of various shapes, connected in its turn to the common shaft having such a diameter and height as to permit to be conveniently handled.
- This specific tool which is well-known and for this reason will be briefly described, is generally equipped with a further device having hollow circular shape (which will be called hereinafter “wringer”) and holes or openings on its surface, as well as lateral wings used for the assembly by fitting or by simple laying on the edges of a common bucket; by means of this device, filling just one portion of the open upper space of the bucket, the user can dip the cloth of the mop into the mixture of water and soaps contained inside, then he/she can easily lift the mop and wring it inside the hollow holed portion of the cited device.
- Wringer hollow circular shape
- this operation is carried out by a combined action of pressure and rotation of the mop inside the "wringer", so as to eliminate the water in excess adsorbed by the cloth that, through the holes, falls in the bucket or, in more complex models, in a suitable distinct sector created inside the same bucket in order to separate the clean water from the dirty water.
- these manufacturing variations does not affect at all the dynamic, the advantages and the effectiveness of this invention, as it can be anyway applied on any type, shape, size or model of holed "wringer" device.
- the above-described invention is disclosed by the patent No. DE 19503572 .
- the very old Patent GB 422660 proposed a mop wringing device comprising a frame 11 provided with hooks for engaging the top of a pail.
- the frame comprises essentially two angle bars 19 connected with a plate 18a and pivotably connected with members 11a on the bottom of the bars and adapted to be positioned inside the pail.
- Lateral plates 18b forms together with plate 18a a pocket for receiving the mop to be wringed.
- a plates 27 is connected pivotably inside said pocket.
- a bar 30 (positioned inside the pail) is connected with frame 11a by its first end and with its other end touching the plate 27 via rollers 33.
- a hook 21 is adapted to receive the handle of the mop.
- angle bars 19 with pocket are essentially emerging from the pail and supported by supported pivotably by members 11a.
- the wet mop will be placed in the pocket with its handle engaged into the hook 21.
- the operator can swing the mop handle swinging in this manner plate 18a and plate 27 toward the left, via the bars 19.
- plate 27 become engaged by rollers 33 fixed on the bar 30 such that they move upwardly on plate 27, pivoting it toward plate 18a. The mop is thus squeezed between plate 18a and plate 27.
- a mop wringer 10 comprising a base 12 and side walls 14 defining a channel 16 in which a mophead 28 can be fit.
- One or more openings 21 in the bases and on the sides are provided, such that the fluid of the mop can drain through them.
- the device can include a guide element 38 which is pivotably displaced relative to the channel 16 and which replace one of the fixed walls 14 such that to make adaptable the channel for several dimensions of the mop.
- a pivotable elongate member 44 is connected operatively with yoke elements 48. Moving the elongate member towards the head of the mop inside the channel the yoke elements 48 rotate via a pivot and become positioned on the mop impressing a force on the absorbent material 32 and winging it.
- the present invention aims at avoiding the above-mentioned and other drawbacks, supplying a manual device, ergonomic and highly effective, requiring limited specific operative force, easy to use, having few risks of reversal, which can be applied as accessory to existing buckets or integrated in future productions, with the characteristics described in the independent claim.
- Other characteristics of this invention are the object of dependent claims.
- the advantages resulting from the present invention essentially consist of the fact that it's possible to wring the cloth using a correct balance of the forces and avoiding recurrent cases of reversal of the bucket; that it allows the user to never separate his/her hands from the object and to exert a greater pressure on a direct point load; that the use of the lever activated by the shaft avoids the need to bend down, as it occurs in the current lever systems; that the lever, activated in opposite direction, offers possibility of exceptionally ergonomic support of the shaft, useful both during the temporary breaks from work and for stowing the object homogeneously; that the use of this invention with the lever system produces greater results than a direct compression system; that, suitably sized, it can be suited to any type of existing bucket, regardless of the dimensions, shape and type (with single or double tank).
- This invention whose shape and size can vary in infinite executive solutions, consists of a particular device comprising a wringing lever, preferably made by plastic pressure casting, with hinge point connected to the holed basket holding the cloth, or mop, during wringing.
- the lever is essentially constituted by a vertical and flat post (10), with two perpendicular wings (16) rigidly connected to the post and emerging outward from it, of suitable length and symmetrical shape, on its sides; these wings have two opposite holes (5) at their base, in axis each other, where the pivot or hinge axis enter, causing the lever rotate (the angular wideness of this rotation will be better specified hereafter).
- the rotation of the lever is controlled by the shaft (3) of the cloth that, inserted through a hole (8) on an upper handling level or upper surface (9) of the same lever, allows the two middle shaped wings to press on the plastic end of the shaft of the mop, containing the various strings of absorbing material.
- the lever controlled from vertical position, acts on the final portion of the shaft already handled by the user, so increasing the force applied for pressure on the cloth, exerting on the system a mainly vertical action, with the consequent advantage of keeping the system balanced, avoiding any risk of instability nowadays known to anyone works with these tools.
- cloth or “mop” we mean hereinafter a device principally used for washing floors, made of a series of strings in cloth or other material, either alone or together with the shaft for its use. Therefore, the term “cloth” should not be considered restrictive only to items made of cloth.
- said device to wring a cloth (2), or mop, like the one used for washing floors comprises a wringing lever(1) adapted to be applied to a bucket or to a holed basket (4) where the cloth (2) to be wringed is inserted of a bucket (6).
- the wringing lever (1) consists of:
- said wringing lever (1), or lever (1) is hinged directly or by suitable interface to a typical holed basket (4) contained in a bucket.
- this device is directly activated by positioning of the shaft (3) in suitable place with appropriate direction, by means of its extensions, it presses the cloth strings, contained in the plastic final portion of the same shaft, inside the holed basket.
- the wringing lever (1) comprises a flat post (10) with the two side wings (16) extending forwards on the post (10).
- it is L shaped and comprises an upper surface (9) perpendicular to the post (10).
- the upper surface (9) comprises a hole (18) and an opening (8) connected to said hole, said hole and said opening being passing through the entire thickness of the upper surface such that the shaft (3) with its cloth (2) can be inserted into the hole through the opening (8).
- Said device (1) is led in rotation by the same shaft, until such a position that guarantees a static balance of the system in a convenient position to restart the specific operations.
- This device (1) includes a rotation point (5) and a sector (11) below that forms with the post (10) an angle defining the stop point of the same lever in opening position, which can vary according to the needs and/or sizes of the entire device the system is applied to.
- the sector (11) extends downwardly respect to the post and forms with said post (10) an angle defining the stop point of the lever in opening position.
- the lever (1) comprises two shaped wings (16), parallel each other and perpendicular to the vertical post (10), placed at reciprocal suitable distance to hold the shaft and act in contrast inside the basket (4), without obstacles or mechanical stops, until the desired draining of the cloth.
- the lower surface of said wings has a slightly curved shape in order to exert a greater pressure on the cloth.
- Said wings (16) are perpendicularly directed to the vertical post (10) and shaped so as to enter, with fixed approach, the holed basket (4).
- These wings (16) are made so as to exert, on the final portion of the shaft containing the cloth strings forming the mop, a perpendicular pressure to the laying level of the bucket, in order to reduce as more as possible the component of transversal force given by the lever, which is however counterbalanced by the useful supporting surface, larger than the traditional dynamics.
- This invention comprises means to exert said force (F) necessary for the compression of the cloth or similar, consisting of an upper handling level (9), perpendicular to the post (10) and long enough, inside which the shaft moves in the above described operation.
- a stop (11) consisting of a lower wing, made on the lever (1) at the base of the hinge (5) against the external wall of the holed basket (4).
- the wringing lever (1) In particular for connecting the wringing lever (1) to the holed basket or to the bucket, the wringing lever (1) comprised two pivot holes (5).
- a fork formed by two holed parallel wings (13) is connected via a plate (12) on the external back surface of the holed basket or the bucket, said holed wings (13) being hinged to the pivoting holes (5) of the wings allowing the rotation of the wringing lever towards the mop and vice versa such that the wings (16) press the mop inside the basket and the reverse movement of the shaft towards the point (20) of the hole (18) carries the lever back in rest position.
- a wrinkling unit to wring a cloth, or mop, like the one used for washing floors is provided. It is consisting of a bucket (6), a holed basket (4) where the cloth (2) to be wringed is inserted and a wringing lever (1) that is operatively applied to said holed basket or to said bucket, said wringing lever comprising:
- the lower surface of said wings has a slightly curved shape in order to exert a greater pressure on the cloth.
- Said wings (16) are perpendicularly directed to the vertical post (10) and shaped so as to enter, with fixed approach, the holed basket (4).
- These wings (16) are made so as to exert, on the final portion of the shaft containing the cloth strings forming the mop, a perpendicular pressure to the laying level of the bucket, in order to reduce as more as possible the component of transversal force given by the lever, which is however counterbalanced by the useful supporting surface, larger than the traditional dynamics.
- Figs. 1 and 2 show a whole transversal section of the two relevant positions of the working dynamic of this invention.
- Fig. 1 shows the shaft of the cloth in "rest” position, after the insertion of the final portion with cloth (2) inside the holed basket (4).
- This first figure shows the wringing lever (1) hinged by passing pivot (5), in order to get an angular movement (alpha) variable according to the type and dimension of the standard accessories of the cleaning device.
- the basket (4) is commonly fitted on a traditional bucket (6), regardless of its shape because it does not affect the dynamic of the invention.
- the shaft (3) is inserted into suitable hole (8) on the upper handling level (9) of the laver, as depicted in next Fig. 3 , showing the back view -A-.
- the support (12), equipped with transversally holed wings (13) for the hinge pivot (5) (depicted in the back view of Fig. 3 and in relative detail "Z"), can be part of the holed basket (4) in a new manufacturing, or assembled to a common existing basket.
- the angle of the stop point of the final portion of the lever (11) with the support (12) connected to the basket (4) entails a position of the shaft (3) that makes its catch convenient and rapid; as depicted in Fig. 2 , the catch is naturally fulfilled exerting on the same shaft a force (F) that, thanks to the insertion of the shaft (3) inside the hole on the upper surface or handling level (9) of the wringing lever (1), causes it rotate.
- the two wings (16) of the lever suitably shaped and placed at fixed distance, thanks to their rotation around the hinge axis (5), press the final portion in plastic (17) on the shaft (3) containing the cloth strings forming the mop.
- Fig. 4 shows this dynamic depicting the described position in front view, with the two wings (16) acting on the final portion (17), while the specific detail "X" shows a transversal view of a further position.
- this invention considerably reduces such transversal component, thanks to the pressure angle that the wing (16) exerts on the final portion (17) of the shaft.
- this component is sufficiently balanced thanks to the resisting plane (b) ( Fig. 2 ), not centred in the bucket, therefore with barycentre placed in advantageous position compared to the exerted action, differently from what happened before with not guided vertical action.
- FIG. 5 shows the lever (1) only bound to the basket (4), for every type of existing or designed bucket, single or with two separate chambers for clean and dirty water, preserving all its advantageous characteristics.
- This figure represents a transversal section of the holed basket (4), showing in the back portion the fixing plate (12), fixed to the basket by means of screws (14) and equipped with two wings (13) forming the fork with the pivot (5) around which the lever rotates; the depicted position is the final opening of the lever, obtained by the stop of the lower wing (11) of the lever (1) on the plate (12) or, when it is integrated during manufacturing, on the same basket (4).
- the position obtained and mechanically imposed permits to get a sloping angle of the shaft (3), inserted into the longitudinal hole on the handling level (9), which is ergonomically advantageous in the next catch.
- FIG. 6 shows the possibility of the lever (1), through its middle wings (16), to substantially enter the basket (4).
- this position in the working dynamic, will be never reached, but the mechanical possibility of this position implies that the pressure exerted by the wings on the mop has the only bind of the physical bulk of the cloth to wring, so permitting to get, according to the pressure exerted on the shaft, such a final draining (given by the wringing of the cloth) free from mechanical limits.
- Figs. 7 and 8 show a back view of the lever (1) assembled on the holed basket (4).
- Fig. 7 shows a system consisting of a fork made by a base plate (12), fixed on the basket by means of screws (14) or any other known system, connected with the two wings (13) with the hinge pivot (5), where the hinge point of the lever (1) fits.
- Fig. 8 only differs because it shows a possible production of the object for this purpose, equipped with the wings (13) directly made from the plastic casting of the holed basket (4).
- Such a manufacturing method permits the application of the lever in a very simplified structure, actually providing the accessory in integrated, economical and working solution.
- Fig. 7 also illustrates in back view the angled position of the lever (1) showing its shape, with its flat post (10), vertically developing on the hinge point (5), and, below, the stop wing (11).
- Perpendicular to the post (10) there is the upper sector (9) of the lever (1), with side opening (8) for the insertion of the shaft (3) and a central hole (18), perpendicular to the entrance opening (8), having two ends constituting respectively the rest point in opening position of the lever (20) and the opposite point (19) for exerting on the shaft (3) the pressure sufficient to drain the cloth, as above described.
- FIG. 9 shows the single upper sector (9) of the lever (1), so as to better highlight the notch made on it: a top view shows the upper level (9) perpendicular to the post (10), with a side (right or left) opening (8) large enough to receive the diameter of the shaft of the mop. Said opening (8) is transversal to the level (9) and centred, departing from it two opposite directions (19) and (20).
- FIG. 10 shows a perspective view depicting the physical structure of the lever, object of the present invention.
- Fig. 10 shows a lever (1) made by a flat post (10), which is divided.by a transversal hole (5), being the rotational point, in an upper part constituted by the cited post and a lower part constituted by a smaller sector (11) that can better enter as stop inside two parallel holed wings forming a fork connected to the holed basket around which the lever (1) is bound in rotation.
- the angle that the lower wing (11) forms with the post (10) will define the stop point of the same lever in opening position, which can vary according to the needs and/or sizes of the entire device the system is applied to.
- two opposite and parallel wings (16) extend perpendicularly to the vertical post (10) and are shaped so as to enter, with fixed approach, the holed basket (4). These wings (16) are made so as to exert, on the final portion of the shaft containing the cloth strings forming the mop, a perpendicular pressure to the laying level of the bucket, in order to reduce as more as possible the component of transversal force given by the lever, which is however counterbalanced by the useful supporting surface, larger than the traditional dynamics (see Fig. 2 ).
- This example shows a side opening (8) large enough to conveniently receive the shaft of the mop.
- This side opening (8) connects the outside of the upper level (9) with the central hole (18), departing from it the two opposite directions.
