    Chain cleaner
    The present invention relates to a chain cleaner, which is arranged for treating a drivable chain, for instance a bicycle chain, with a liquid, the chain cleaner comprising: a housing, formed from a container for the liquid and a lid that can be coupled to the container, wherein the housing at least comprises an entrance opening and an exit opening for passage through the housing of the chain to be treated in operation; movable brushes arranged to each engage one side of a chain for treatment, the chain cleaner being arranged such that the chain, by its propulsion, drives the brushes for their movement.
    Such a chain cleaner is known from German Offenlegungsschrift DE 3,839,076. In the known chain cleaner, the bristles protrude radially in whorls from three rotatably mounted drums above and below the web for a chain to be cleaned, the center lines of which run perpendicular to the web direction. The brushes are driven directly for their rotational movements by the chain moving in operation along the drums. The brushes also serve to distribute a cleaning fluid between the chain foams through which the chain is passed. By guiding the chain along a set of stationary further brushes, the excess liquid is removed from the chain.
    The disadvantage of the chain cleaner according to the known art is that its effect is insufficient. In the case of a cleaning treatment, this treatment is highly dependent on the brushing action of the brushes. This brushing action only takes place when the brushes engage on the chain, which is only a short period of time. In the case of a different treatment, for example lubricating the chain, the brushes do not penetrate the chain sufficiently to achieve adequate lubrication.
    The object of the invention is to eliminate at least the above drawback, and to this end it provides a chain cleaner, which is distinguished by at least four movable brushes, which grip the chain to be treated on its four sides, at least one rotatably mounted in the housing sprocket positioned to engage the chain in operation to be driven therethrough, and transmission means between the first sprocket and the brushes, which transfer means the rotation of the first sprocket as a result of its driving through the chain in operation convert into a movement of those brushes at a substantial speed relative to that of the chain, at least in the plane of engagement of the brushes on the chain.
    Due to the substantial speed difference between the brushes and the chain, at least in the area of engagement of the brushes on the chain, the brushing action of the chain cleaner according to the present invention is very effective.
    Furthermore, applying a chain cleaner according to the present invention does not require any special operation, such as releasing the chain, which would involve an intervention in a chain-containing machine, such as the bicycle.
    In addition, the chain cleaner of the present invention includes at least four movable brushes which engage the chain to be treated on its four sides. A chain to be treated is hereby treated from all relevant directions, further enhancing the effectiveness of the chain cleaner of the present invention.
    It is noted that a chain cleaner of the type mentioned at the outset is known from German patent 92.11.32. In the known chain cleaner, the brushes are mounted on rotatable drums, 45 such that the brushes engage on the two sides of the chain. The drums are rotated by movement of the chain. The known chain cleaner has the drawback that the brushes move with the chain in the engaging surface. In addition, the brushes only engage on two sides of the chain. With the known chain cleaner, the cleaning effect will therefore be considerably less intensive than with the chain cleaner according to the invention.
    A particular embodiment may have the feature that the brushes are movable with the direction of movement in a plane substantially perpendicular to the bristle direction. Due to this movement of the brushes, a good brushing effect is obtained, it being noted that, in particular, a rotating drive of the brushes can easily be effected with the aid of the gear wheel.
    Preference is given to an embodiment in which the brushes are mounted in the housing for rotation 55 around respective axes transverse to the feed direction of a chain. Such an embodiment has the advantage of being able to make use of simple rotary transmissions by means of gears which cooperate with each other in one main plane or at right angles, respectively, whereby no special reversing means are required for periodically reversing the movement device of the brushes. A chain cleaner, provided with brushes mounted in a housing for rotation about a respective axis, transverse to the feed direction of a chain, is known from German patent 92.11.32. In the known chain cleaner, the brushes are fixedly connected to a wheel and are driven directly by the chain in rotation. It is noted that such a chain cleaner is also known from DE 3839076.
    In a preferred embodiment, the chain cleaner according to the invention has the feature that the first sprocket is carried by a shaft, on which on either side a respective second and third sprocket is mounted, which drives a fourth and a fifth sprocket respectively, to which a first and a first sprocket drive. a second brush is provided, which fourth or fifth gear wheel also co-operates for angular transmission with a sixth and seventh gear wheel, to which respectively a third and a fourth brush are arranged, which seventh gear wheel is mounted on a lid cooperating with the box. This preferred embodiment can be manufactured in a mechanically solid manner at a low cost. This preferred embodiment can moreover be designed in a very compact manner.
    The chain cleaner can advantageously have the feature that the second and the third sprocket are coupled to each other by shaft parts integrated therewith, respectively, with securing intermediate placement of the first sprocket. This embodiment also contributes to a compact design of the chain cleaner according to the invention.
    With one injection mold for the second and the third gear, respectively, with associated shaft part 20, it is sufficient in an embodiment in which the shaft parts are complementary and identical. For example, by clamping, snapping or other suitable means, the relevant shaft parts can be coupled to each other and the first gear wheel.
    All parts can preferably be removable, for example for cleaning purposes.
    In general it can be advantageous if all parts of the chain cleaner are injection molded parts. The brush means to be described below can also be designed as injection molded parts. The use of injection molded parts for the parts of the chain cleaner is particularly advantageous with a view to mass production.
    With the chain cleaner according to the invention, the chain to be treated may not be passed through the treatment liquid. Should this be the case, a brushed chain leaves the brush means in dripping wet condition, which is not desirable. However, the chain must be moistened with treatment liquid. Good wetting is ensured with an embodiment in which the second and / or the third sprocket carries blades for transferring liquid present in the container to the chain.
    A simple pouring of cleaning liquid without spillage is ensured with an embodiment in which the tray has a recessed input part serving as an input opening for the chain, which also functions as a pouring opening for liquid. In this embodiment, the function of the inlet opening of the chain and the function of the pouring opening are combined in a very simple and natural manner.
    Preferably, the chain cleaner is treated by the chain cleaner in such a way that the chain leaves the chain cleaner without any adhering liquid. For this purpose the container of the chain cleaner has a recessed rim portion 40 serving as an outlet for the chain, in which there are stripping means for stripping adhering, surplus liquid from the chain, characterized in that the stripping means are brushes and that at least two are connected to each other adjacent brushes extending transversely to one another are pivotally coupled to one another. In the chain cleaner known from DE Offenlegungsschrift 3839076, scraper means in the form of slats are used and at least two of the 45 adjacent, mutually transverse slats are coupled to each other.
    The advantage of the chain cleaner according to the invention is that two or more adjacent brush elements can together form one injection molded part and can be hinged relative to each other during the assembly of the chain cleaner to be included in the chain cleaner.
    50 The seventh gear wheel mounted on the cover could become lost from its bearing position when the cover is removed. In order to avoid this inconvenience, the chain cleaner is preferably characterized by a locking lip present on the lid for holding the seventh sprocket in position.
    The invention will now be elucidated with reference to the drawing. Herein: figure 1 shows a partly cut-away perspective view of a chain cleaner according to the invention with the lid removed; o ι »ουο <: figure 2 shows a longitudinal section through the chain cleaner according to figure 1; figure 3 shows a scraper brush element; and Figure 4 shows a detail of a wetting blade.
    Figures 1 and 2 show a chain cleaner 1 for a bicycle chain 2. For this purpose, the chain cleaner 1 comprises a container 4 which can be covered by a lid 3, in which treatment liquid can be received, the level of which is indicated by the reference number 5 in figure 2. The tray 4 and the lid 3 hereinafter described rotatably drivable brushing means, to brush the chain 2 from four sides.
    A first sprocket 6 is rotatably mounted in the gearbox 4, the top of which can be brought into co-operation with the chain 2 in its or at least substantially tensioned operating position. Furthermore, there are transmission means between the first sprocket 6 and the brushing means, whereby the drive by a moving chain 2 via the sprocket 6 is converted into a rotating movement of the brushing means to obtain a substantial relative speed relative to the chain.
    The first gear 6 is carried by a shaft 7, on which a respective second gear 8 and a third gear 9 are arranged on either side, which drive a fourth gear 10 and a fifth gear 11, respectively, to which a first brush 12 and a second brush respectively brush 13 is provided, which fourth gear 10 also cooperates for angular transmission with a sixth gear 14 and a seventh gear 15, to which are respectively mounted a third brush 16 and a fourth brush 17, which seventh gear as shown in Figure 2 cover 3 is mounted, while the sixth gear 14 is mounted on the box 4.
    As Figure 2 shows, the gears 14 and 15 are axially mounted by means of thrust bearings. Cylindrical bushes 35, 36 provide radial bearings.
    The second gear wheel 8 and the third gear wheel 9 are coupled to each other by shaft parts of the shaft 7 integrated therewith, with interlocking insertion of the first gear wheel 6. These shaft parts are complementary and identical.
    The second sprocket 8 and the third sprocket 9 carry blades 18 with incised free ends for applying treatment fluid contained in the tray 4 to the chain.
    The tray 4 has a recessed rim portion 19 serving as an inlet for the chain 2, which is also formed such that it is suitable as a pouring opening for finished treatment liquid.
    The tray 4 also has a recessed edge portion 20 serving as an output opening for the chain 2, in which scraper brush means 21 are provided for wiping off excess liquid from the chain 2.
    Figure 3 shows a scraper brush element 22, a number of which together form the scraper brush means 21. Three adjacent scraper brushes 23, 24, 25 extending transversely to one another are hingedly coupled together to form the scraper brush element 22.
    The cover 3 has two locking lips 26, 27, which protect the seventh gear 15 from falling out of the cover 3.
    The tray 4 in this embodiment is made of transparent plastic.
    The chain cleaner works as follows. In the open position shown in figure 1, the tray 4, in which 40 all the associated parts are located (attention is drawn to the fact that the gear wheel 15 shown in figure 1, when the cover is removed, is located on the inside of the cover) is placed from the bottom against the chain 2 to be cleaned. Then, after the first sprocket 6 has been brought together with the links of the chain 2, the tray is covered by the lid 3, which can be brought into position by means of lip connections 28 on one side and 45 snap connections 29 on the other silk. Then the user has to move the chain of the bicycle (or other device). By this movement 30 (see figure 2) the first gear 6 is rotatably driven, thereby moving the second gear 8 and the third gear 9, which respectively drive the fourth gear 10 and the fifth gear 11, whereby the first brush 12 and the second brush 13 are rotatably driven. As a result of the described right-angle 50 transmission, the sixth gear 14 and the seventh gear 15 are also rotatably driven, whereby the third brush 16 and the fourth brush 17 are also rotatably driven. These four brushes brush the long-moving chain from four sides. The blades 18 transfer treating fluid to the chain, the brushes 12, 13, 16, 17 brush the chain, and finally the scraper brush means 21 wipes the excess fluid off the chain, leaving it essentially dry from the chain cleaner.
    The treatment liquid for use with the chain cleaner 1 can be a cleaning component, a lubricating component and a corrosion-resistant component, in particular an aromatic-free

    Chain cleaner according to claim 1, characterized in that the trough has a recessed input section serving as an input opening for the chain, which also functions as a pouring opening for liquid.
    The side brushes 12, 13 have a special configuration. They consist of two rows of bristles arranged side by side, making these brushes 12, 13 self-draining. The wiping brushes 23, 24, 25 also have such a configuration. Here too, by means of this configuration (see figure 3), stripped-off liquid can easily flow back to the tray 4. It is further pointed out that the wiping brushes have blades 33 which, as it were, have a limit chamber 15, thereby preventing the escape of vapors together with the leaving chain 2. The lid is provided with a sealing edge that also serves as a search edge. The blades 18 carry hair-shaped blades 34 extending in the direction of the shaft 7. These hair-shaped blades, of which each of the blades carries six, are dimensioned such that they touch the chain to be cleaned during use. This is necessary for optimum wetting during a quiet use of the chain cleaner, because during rotation the liquid carried by the blades 18 does not go outside the defined shape of the blades. Therefore, in order to wet the chain optimally at a low blade speed, contact between the hair blades 34 (which are also wetted by the liquid) and the side surfaces of the chain is necessary. In addition, this configuration, in conjunction with the selected round shape of the tray 4, ensures that a very small amount of liquid is sufficient for proper operation. The fourth gear 10 and the fifth gear 11, which respectively carry the side brushes 12 and 13, are lightly secured in their position, although freely rotatable, by means of a very small undercut, such that when the liquid is poured out via the " spout "19 all parts remain in place. This is also the case with the scrubbing brush means 21, which remain snapping in place. The construction nevertheless ensures that all parts can be removed if desired. However, the vertical positioning of the gears 10, 11 and thus of the brushes 12, 13 secured by the construction shown in figure 1, using two supporting partitions and an outwardly inclined bearing mounted downwards.
