Abstract
A portable wringer 11 for a chamois leather comprises a support structure 12, and a pair of rollers 13,14 driven by a crank handle 15. The support structure 12 carries a suction device 18.
Description




The present invention relates to a portable wringer and more particularly to a portable wringer for removing liquid from a wet leather, cloth or piece of fabric. It is especially intended for wringing water out of chamois leathers used for washing automobiles and other vehicles, but is not restricted to this purpose.




When washing water is removed from a vehicle using a leather, the leather has to be wrung out. When the operation is carried out by hand, it is difficult to obtain an even degree of dryness. At the same time it can cause chaffing of the hands and the leather can become stretched. Additionally, the wrung-out water can find its way to the clothes or feet of the user.




Clearly, therefore it would be advantageous to employ a mangle or wringer. However a fixed mangle would be inconvenient since it would necessarily be located at a distance from at least parts of the vehicle being washed and this would require the person washing the vehicle to walk back and forth to the mangle. Portable mangles have therefore been proposed and one such device is designed to clip over the window of vehicles for example as shown in FR-2571391. However, this device suffers the disadvantage that it can not be sufficiently rigidly attached to the window so that operation of the mangle causes the device to wobble. Also, the integrity of the window seal is compromised leading to a risk that water might enter the vehicle and mark the upholstery. Furthermore, the device is impractical if the vehicle is on a gradient since the device itself will be similarly inclined.




What is required, therefore, is a portable wringer that can be firmly and reliably attached to a vehicle without exposing the interior of the vehicle to the risk of leaks.




According to the invention, there is provided a portable wringer for removing liquid from a wet leather, cloth or piece of fabric, which comprises: a support structure; a pair of rollers rotatably mounted on the support structure; means for urging the rollers together towards a position in which the surfaces of the rollers would make mutual contact along their respective lengths; means for rotating at least one of the rollers; and a suction means attached to the support structure, the suction means being arranged to adhere to a smooth surface. A leather can therefore be passed between the rollers as they are rotated. The use of suction means enables the device to be attached to a vehicle window, without affecting the seal of the window.




Preferably, the rollers are cylindrical and are arranged with their axes in parallel and are preferably urged into mutual contact. They may comprise a rigid core coated with a layer of resilient material and preferably have spindles at each end, each spindle being supported in a bearing, the bearings being urged together by resilient means.




Preferably, one of the rollers is operatively connected to a crank handle, whereby the roller can be manually rotated. The other roller may then be free-running and will be driven by frictional contact with the roller which is manually rotated. This would, of course, normally occur via the leather which would be passed between the rollers. Preferably, the rollers are arranged to lie one above the other in use and the crank handle is operatively connected to the lower roller.




Alternatively, the rollers may be connected by gear arrangement or a chain or belt so that both rollers are driven. It is even possible for one or both rollers to be motor-driven for example using battery power. The battery may then be the vehicle battery.




Preferably, the device includes liquid catchment means arranged to receive liquid expelled from the leather by the rollers and an enclosure arranged to receive the leather as it leaves the rollers, in use. This minimises the risk of the liquid removed from the leather soiling the clothes or footwear of the user. It also ensures that the leather itself does not fall to the ground and become fouled with mud, dirt or grit. Preferably the liquid catchment means comprises a tray, the tray having one or more liquid discharge ports. Preferably, any discharge port is arranged to discharge the liquid in use in a direction away from the user. Alternatively, the liquid catchment means would comprise a temporary storage container for the liquid expelled from the leather; the container could be emptied periodically.




Preferably, the enclosure for the leather is located above the liquid catchment means and may include a deflector arranged to direct the leather away from the liquid catchment means in use. Preferably, the device includes a scraper located adjacent the upper and/or lower roller and arranged to lift a leather adhering to the surface of the respective roller. In a preferred embodiment, the scraper is located adjacent the upper roller and takes the form of a brush.




Preferably, the suction means comprises a single suction device though there may be a plurality. It preferably comprises a flexible disc having a central portion which is movable rearwardly from the plane of the disc in a direction towards the rollers by means of a cam arrangement. Preferably, the camming action of the cam arrangement is activated by a lever movable in a plane generally parallel to the plane of the disc. Preferably the lever swings in an arc above the level of the cam arrangement, the enclosure and the liquid catchment means, in use. Preferably, the cam arrangement has a cover extending into the enclosure, the cover being arranged to deflect the leather upwards as it leaves the rollers in use. Preferably, the wringer includes a manual engagement area at a position opposite to the suction means. Preferably, the manual engagement area is positioned opposite the centre of the suction device.




In a preferred embodiment, the suction means comprises: a flexible disc; a support member having a concave portion facing the disc; a camming arrangement on the opposite side of the support member to the disc; and a connecting member passing through the support member and connecting the disc to the camming arrangement, whereby operation of the camming arrangement moves the connecting member and draws the central area of the disc into the concave portion of the support member; and in which the camming arrangement includes first and second cam members which have engaging cam surfaces, the first cam member being movable in an arcuate path in a plane generally parallel to the plane of the disc.




This construction eliminates the need for any operative components in the area behind the camming mechanism, though this is not strictly essential and other arrangements of suction devices may be employed.




Preferably, the disc is made of rubber or a plastics material. Preferably the support member is in the form of a rigid circular cup of metal or plastics whose rim engages the rear surface of the disc and whose diameter is smaller than the diameter of the disc. Thus, when the central area of the disc is drawn into the cup, the protruding outer periphery of the disc maintains contact with the surface of the article which is to be engaged by the suction device, and permits the suction device to adhere positively not only to flat surfaces but to curved surfaces also. The device is even applicable to surfaces which are curved in more than one direction, for example vehicle windows.




Preferably, the connecting member is a rod which is attached to the disc. Preferably, the camming arrangement includes an operating lever connected to and extending generally radially from the first cam member, whereby movement of the lever causes the first cam member to follow its arcuate path. Conveniently, the first cam member has an arcuate cam profile defining its cam surface while the second cam member is a cam follower and is connected to the connecting member. Alternatively, the first cam member may constitute the cam follower and the second cam member may define a stationary profiled cam surface.




Preferably, the connecting member is a square cross-section rod which passes through a correspondingly square shaped hole in the support member, and which is rigidly attached to the disc at one end, and which is non-rotatably attached to the second cam member. Cross-sectional shapes other than square may be used, though if the rod is to be prevented from rotating, a round cross-section is preferably avoided.




Preferably, the arcuate cam profile of the first cam member is coaxial with and extends about the rod, whereby an arcuate movement of the handle causes the arcuate cam profile to follow its arcuate path which in turn causes the cam follower to move in the axial direction without any rotation, thereby drawing the central area of the disc into the concave portion of the support member. In a preferred embodiment, the arcuate cam profile comprises a pair of similar ramps following part circular paths in the same sense and at the same radius, the paths extending between a low position and a high position, and in which the second cam member comprises a pair of bosses which constitute the cam follower, attached to a common base, the base being non-rotatably attached to the rod by means of a pin passing through both the rod an the base.




Thus, when the disc is in a relaxed condition, it is slightly spaced from the support cup and the bosses lie on the ramps at the low positions. As the lever is moved through its arc, the first cam member rotates with it, and the ramps follow their circular path. The bosses which are rotationally fixed, travel along their respective ramps from the low position to the high position and in so doing move the rod axially rearwards. This in turn draws the central area of the disc into the cup, so tending to form a vacuum between the disc and any smooth surface with which the disc may be in contact. The vacuum is then released by reversing the operation.




The suction means may include a cover over the camming arrangement, which may be detachably connected to the first camming member. The device may also include a compression spring acting between the rear of the disc and the inside of the support cup, the spring acting to bias the disc away from the support member.




Preferably, the surface of the support member which engages the disc is provided with one or more protuberances, the protuberances being arranged to deform the resilient material of the disc on engagement, thereby positively preventing any significant relative rotational movement between the disc and the support member. This is a very significant feature, because it is important that the wringer should be prevented from tilting or rotating to one side or the other.




The disc preferably has at its centre a rounded protrusion which serves several purposes. Firstly, when the suction device is offered up to a rigid surface to which it is to be attached, moderate pressure applied by the operator's hand causes the protrusion to cause an initial slight dishing of the disc as the disc bears against the support member on an annular contact ring inboard of the extreme periphery of the disc. Further pressure causes the disc to be seated against the rigid surface to which it is to be attached. This seating may occur at the periphery of the disc (especially in the event of its meeting a convex surface) or in line between the support member and the rigid surface (especially if meeting a flat or flatter surface). The resultant contact of the disc at or near its periphery throughout 360°, plus the slight displacement (hollowing) of the “rubber” disc, causes a small amount of air to be expelled resulting in a relatively negative air pressure between the disc and the surface. This minimal negative air pressure is however not sufficient to do more than seal the disc onto a flat or slightly curved rigid planar surface. With the initial sealing having been effected, however, when the centre of the disc is drawn back by operation of the lever, the negative air pressure will increase.




A second purpose of the protrusion is to avoid what may be termed “phantom suction” such as may be experienced when the device is laid at rest on a flat surface.




A third purpose of the protrusion is to assist in removal of the device. If the protrusion were not present, there would be a potential that after reversing the action of the lever, some adhesion and/or residual suction might develop between the rubber disc and the rigid surface to which it was attached, and the device might stay adhering for a few second and then fall off. However, the protrusion helps to break the residual adhesion, so that when the lever is reversed, the device will detach under gravity into the control of the operator.




Preferably, the support structure comprises a pair of side walls, a base and an end wall, and in which the end wall carries the suction means, the sidewalls and base extend rearwards from the end wall in a direction towards the rollers, and the rollers extend between the side walls at a position spaced from the end wall. There may also be a cover partly surrounding the upper roller. Preferably, the cover constitutes optionally together with the upper roller itself, a carrying handle for the wringer. Preferably, the manual engagement area is constituted by a transverse wall portion located below the level of the cover.











The invention may be carried into practice in various ways and one embodiment will now be described by way of example with reference to the accompanying drawings, in which:

Referring to

FIGS. 1 and 2

, the portable wringer


11


comprises a support structure


12


, a pair of rollers


13


,


14


, a crank handle


15


, liquid catchment tray


16


, a manual engagement portion


17


and a suction device


18


. The support structure


12


comprises a pair of side walls


19


, a base


21


and an end wall


22


. The end wall


22


carries the suction device


18


.




The rollers


13


,


14


each comprise a metal shaft


23


10 mm in diameter and a 10 mm thick layer of rubber


24


, giving an overall diameter of 30 mm. The rubber has a Shore hardness of 60/65. The rollers


13


,


14


are mounted one above the other in respective bearing blocks


25


,


26


. The shafts


13


are received by the bearing blocks


25


,


26


via washers


27


. The bearing blocks


25


,


26


are received in two housings


28


, one located at the rear end of each side wall


19


. The housings


19


are closed at their upper ends.




The lower bearing blocks


26


are located in the housings


28


by means of pins


29


which pass through corresponding holes


31


,


32


in the lower bearing blocks


26


and housings


28


, respectively. The upper bearing blocks


25


are urged downwardly by a pair of spring members


33


made from a resilient polyurethane material having a Shore hardness of 85/95. The spring members


33


act between the upper surfaces of the housing


28


and the upper bearing blocks


25


and in this way, they urge the surfaces of the two rollers


13


,


14


into frictional contact.




The manual engagement portion


17


is at a level which is slightly above the nip between the rollers


13


,


14


, and extends rearwardly a little further than any other part of the wringer


11


.




The suction device


18


comprises a flexible rubber disc


34


, a rigid support cup


35


attached to the support structure


12


, a camming mechanism


36


including a first cam member


37


and a second cam member


38


, and a cover


39


. The disc


34


is circular and has a square section metal rod


41


protruding rearwards from its centre. The rod


41


is fixed to a rigid plate (not shown) which is embedded in the disc


34


. The front surface of the rigid plate is fixed to the disc


34


, which the rear surface of the rigid plate, from which the rod


41


extends, is not. This allows relative movement between the material of the disc


34


and the rigid plate which is important when the device is activated and the disc


34


adopts its concave position.




The support cup


35


has a circular rear wall


42


and a peripheral collar


43


but has a smaller diameter than the disc


34


. It has a circular recess


44


in the rear wall


42


, and a square hole


45


in the recess


44


.




The first cam member


37


is a generally cylindrical member


46


having a slightly smaller diameter than the recess


44


. The rear circular rim


47


of the member


46


defines a cam surface which comprises two ramps


48


, each extending in the same sense (anti-clockwise in

FIG. 5

) from a low position


49


to a high position


51


. Each ramp


48


extends through an arc of about 90°. A lever


52


extends radially from the cylindrical member


46


and has a tapped hole


53


at its base.




The second cam member


38


comprises a thick circular disc


54


with a square central hole


55


. A bore


56


extends from one side of the disc


54


through to the other side, notionally extending through the square hole


55


. A circular boss


57


protrudes radially outwards from each side of the disc


54


. The diameter of the disc


54


is slightly smaller than the internal diameter of the cylindrical member


46


.




The cover


39


is conical with a rounded apex and a slot


58


in its periphery. It also has a countersunk hole


59


near the rounded apex.




Referring now to

FIG. 3

, the front edge of the collar


43


of the support cup


35


has a pair of diametrically opposite studs


61


. The studs


61


face towards the disc


34


.




When fully assembled, the rod


41


on the disc


34


passes through the square hole


45


in the support cup


35


then on to the cam arrangement


36


. The cylindrical member


46


of the first cam member


37


fits into the recess


44


in the support cup


35


with a washer


63


spaced between the components. The rod


41


is located in the square hole


55


in the disc


54


and is held in position by a pin


64


which is inserted into the bore


56


and passes through a hole


65


in the rod


41


.




The disc


54


fits within the cylindrical member


46


(as shown in FIG.


4


). The circular bosses


57


lie on the ramps


48


and are movable between the respective low positions


49


and high positions


51


. The dimensions of the components and the position of the hole


65


are arranged so that when the device is assembled, with the bosses


48


at the low positions


49


the disc


34


is spaced from the rim of the support cup


35


by a small distance


66


(as shown in FIG.


7


), the spacing being maintained evenly by the optional spring


62


.




The cover


39


is attached by means of a screw or bolt (not shown) which is inserted into the hole


53


in the first cam member


37


via the countersunk hole


59


.




Activation of the device will be described with reference to

FIGS. 5

to


8


. When the device is to be activated, the lever


52


is moved from the position shown in

FIGS. 5



a,




5




b


and


7


to that shown in

FIGS. 6



a,




6




b


and


8


(arrow A). In so doing, the first cam member


37


is rotated through about 90°, about the axis of the rod


41


. The second cam member


38


is restrained from rotation by the square sectioned rod


41


which is located in the square hole


55


and which is itself held against rotation by the square hole in the cup support


35


. The bosses


57


are therefore constrained to follow the ramps


48


as they move through their respective arcs to the position shown most clearly in

FIGS. 6



a


and


6




b.


In following the ramps


48


, the bosses


57


move axially rearwards (to the left in

FIGS. 5



b


and


6




b


), thereby moving the second cam member


38


itself rearwards. This takes with it the rod


41


(arrow B).




As the rod


41


moves rearwards, it draws the central part of the flexible disc


34


into the support cup


35


. If, prior to this operation, the disc


34


is presented (arrow C) to a smooth surface, such as a curved window


67


as shown in

FIGS. 7 and 8

, the drawing-in of the central part of the disc


34


initially brings the periphery of the disc


34


into contact with the window. Continued operation of the lever


52


moves the rod


41


and the central part of the disc


34


away from the window, causing a vacuum in space created


68


. Atmospheric pressure then holds the suction device


33


in place on the window


67


until the operation is reversed.




In order to assist in locating the disc


34


initially against the window


67


, the disc


34


has a rounded protrusion


69


. As the protrusion


69


is brought into contact with a surface, it is pushed inwards and so starts the sealing operation. It also assists in breaking the suction when the device is de-activated and helps to hold the device in position when the vacuum is released.




In order to prevent any small relative rotational movement between the disc


34


and the support cup


35


, the studs


61


shown in

FIG. 3

are provided. When the front rim of the support cup


35


is brought into contact with the disc


34


, the studs


71


dig into the resilient material of the disc


34


. This engagement positively prevents any relative rotational movement between the disc


34


and the support cup


35


.




It will be appreciated that the flexibility of the disc


34


together with the depth of the concavity of the support cup


35


and the relative diameters of the disc


34


and support cup


35


enable the suction device to be used effectively not only on flat surfaces but also on surfaces which are curved in one or more senses.




Thus, the wringer can be securely attached to the window of a vehicle using the suction device


18


. The position of the manual engagement portion


17


over the centre of the suction device


18


ensures a positive initial contact and an accurate engagement between the disc


34


and the window, as initial manual pressure from the palm of the hand is applied to the manual engagement portion


17


.




Reverting to

FIGS. 1 and 2

, one end


71


of the shaft


23


of the lower roller


14


extends out beyond its bearing block


26


and is formed with a bore


72


. This protruding end


71


is received by the crank handle


15


and is located by means of a pin


73


. Thus, as the crank handle


15


is rotated, it rotates the lower roller


14


which in turn rotates the upper roller


13


through mutual frictional contact.




The dimensions of the side walls


19


and the crank handle


15


are arranged to provide sufficient clearance when the device is in use between the knob


74


of the crank handle and any surface to which the device is attached. In order to assist in achieving this situation, the knob


74


has a concave profile which readily receives the forefinger of a user.




In use, a leather is placed in the nip between the rollers


13


,


14


and the crank handle


15


is turned manually, with the forefinger of the user wrapped around the knob


74


. The fact that the manual engagement portion


17


is above the nip means that the leather is inclined downwards to the rollers


13


,


14


as it passes over the manual engagement portion


17


. This ensures that expelled liquid does not run back along the leather, but remains at the rollers


13


,


14


and drains down on to the catchment tray


16


. Thereafter, the liquid drains over the edge of the tray which is beneath the suction device


18


. The edge of the tray


16


protrudes to a position which is very close to the window of the vehicle and so the expelled liquid pours on to the window and down to the door sill. This minimises the risk of splashing. The tray


16


is contoured to divert the liquid to a single stream, though it may be arranged to divert the liquid to each side.




The fact that the manual engagement portion


17


is effectively the rearmost part of the device enables a wet leather to hang free from the manual engagement portion


17


. There is therefore little drag on the leather and no snagging as it is drawn through the rollers


13


,


14


.




The leather, as it passes through the rollers


13


,


14


, is diverted upwards, away from the expelled liquid, by the domed shape of the cover


39


. It is then received in the enclosure


75


formed by the sidewalls


19


, the base


21


and the end wall


22


and can be easily retrieved.




In order to ensure that the leather does not adhere to the upper roller


13


, a scraper brush


76


is provided in the upper part of the enclosure


75


. The brush


76


lightly contacts the upper roller


13


and lifts off the leather if it should be wrapped around the surface of the roller


13


. There could also be provided a second scraper brush (not shown) associated with the lower roller


14


, however, tests suggest that there is very little tendency for a leather to adhere to the lower roller


14


.




The scraper brush


76


is located beneath a cover


77


. This cover is positioned adjacent an upper extension


78


of the manual engagement portion


17


. An opening


79


is formed between the upper extension


78


and the manual engagement portion


17


. Thus, the upper extension


78


, the cover


77


and to some extent the upper roller


13


cooperate to form a carrying handle


81


for the device as a whole, with the opening


79


providing a space for the thumb of the user.




The location of the handle


81


above and behind the centre of gravity of the device as a whole means that when the device is carried, it tilts in such a way that the suction device


18


is inclined to the vertical. This means that when the device is offered to a vehicle window, it will be at an appropriate orientation.




Thus, the present invention provides a portable wringer that can be firmly and reliably attached to a vehicle window and which enables a chamois leather, or a cloth to be wrung dry of liquid in a convenient and useful manner.
