Definitions

  • the invention relates to a wiping agent press according to the preamble of claim 1.
  • the generic wiping agent presses have a bucket and a pressing device provided on or in the bucket for squeezing and clamping the wiping agent.
  • the bucket is provided with an upper dipping opening, delimited by a bucket wall, for dipping in a wiping agent of a cleaning system in a dipping direction directed downwards towards a bottom of the bucket.
  • the wiping agent presses are usually provided for wiping agents, which are arranged at the lower end of a handle of a mopping device and from a for example in the EP2868250 A1 described fringed mop, a flat textile or foam layer, wiping fibers or cords or similar materials for moistening, cleaning and/or drying of surfaces are formed.
  • the wiper press according to the invention can also be used for isolated wipers such as chamois leather, cleaning cloths and sponges.
  • the pressing device of the wiper press comprises a first pressing claw and a second pressing claw that is movably mounted at least partially in the bucket or above a liquid-receiving area of the bucket and can be set in the direction of a pressing area of the first pressing claw.
  • Actuating means in particular in the form of a foot pedal, which can be moved by the user and drives a pressing mechanism, are coupled to the second pressing claw.
  • the second press claw is pushed against the active pressing area of the first press claw.
  • the hanging wiper is inserted from above into a folded-up compression space formed by the two compression claws and is usually folded several times and deposited in this compression space.
  • the press claws in turn are designed in particular in such a way that they can grip the hanging wiping means without its one-sided attachment to the wiping plate having to be released, so that the wiping means can be pushed over the handle of the Wiping device introduced into the pressing device and can also be removed from the pressing device again.
  • the generically fixed first pressing claw and a second pressing claw which can be pivoted about a claw pivot axis in the direction of the first pressing claw, are liquid-permeable, for example due to a prong-shaped or fork-shaped claw design, and press out the wiping agent when the actuating means is actuated, while the liquid that is pressed out drips off.
  • the actuating means is a foot pedal that can be actuated from the outside.
  • it can also have a different shape depending on the design of the wiper medium press according to the invention, in particular it can be a lever that the user can operate by hand or a rotary knob or even the wiper plate itself, which is then used via the handle to press down the drive carriage .
  • Wiping agent presses according to the invention can also be designed as a tabletop device, for example for drying by squeezing a chamois leather or for squeezing out plate-shaped wiping plates rotated by 90° and hanging on the handle of the wiping device, which are then inserted vertically into the pressing device.
  • a generic wiper press is from CN 109 700 396 A1 known.
  • the first press claw is fixed in the bucket.
  • a second pressing claw is rotatably mounted on the bucket wall.
  • a vertically movable slide is provided in the bucket, which can be stepped on with a foot pedal. Through a reversal mechanism, this depression of the foot pedal to raise a power transmission component feels the second press jaw pivoting and pressing against the first press jaw.
  • Another wiping agent press is from the CN 209 293 174 U known.
  • a lever drive and a foot pedal are used to press a press claw articulated on the edge of the bucket onto the top of the wiping plate in order to press and squeeze the cleaning agent into a fixed press claw.
  • Complex mechanics are also required here, and the stationary press claw takes up a great deal of space in the bucket, which means that large-volume buckets have to be used.
  • a Mopping agent presses which have a bucket which has a water reservoir in the lower area, this lower area being separated from an upper area by a liquid-permeable grid.
  • the pressing device is provided in the upper area.
  • the pressing device consists of two pressing claws, which are pivoted about two adjacent claw pivot axes. The pivot axes of the claws each run horizontally and at right angles to the vertical bucket wall, so that the pressing claws can be opened with the opening oriented upwards, resulting in a substantially cylindrical pressing chamber running parallel to the bottom.
  • the pressing claws are moved via an actuating mechanism which has a lever arranged on one of the outer walls of the bucket as actuating means. Using suitable sealing means, this lever is guided through an elongated hole into the interior of the bucket, where it is connected to a drive carriage which is movably mounted along the bucket wall against the force of a return spring. On its inner side, the drive carriage has teeth in the manner of a straight toothed rack, which meshes with a toothed gear arranged on the adjacent bucket wall.
  • This gear mechanism has a plurality of individual gear wheels for the transmission and translation of the actuating force and ultimately drives drive axles which are mounted concentrically to the claw pivot axis and to which the pressing claws are attached. Since these drive axles are also interlocked and the drive axle of the first press claw drives the drive axle of the second press claw, the press claws are moved towards each other via the gear drive to reduce the press chamber.
  • Wipe coatings can be squeezed out effectively with this device.
  • the gear drive is comparatively complex to manufacture and assemble and due to the fact that there is usually dirty water in the bucket, there is a risk of non-functioning due to the gear wheels becoming blocked by dirt particles.
  • the storage of the gears requires a massive bucket wall, which in turn leads to high manufacturing costs.
  • the gear wheels can also pinch and damage the wiper or block it as a result.
  • a wiping agent press is known, the pressing device of which is arranged completely outside the bucket.
  • This has a foot pedal arranged next to the bucket wall, which is connected to a pressing device arranged above the opening of the bucket.
  • the pressing device consists of two pressing claws which can be pivoted about a vertical claw pivot axis and which can clamp a hanging wiper covering between them as a wiping means.
  • This device has the disadvantage that, on the one hand, the pressing device is arranged outside of the bucket and there is therefore a risk that spray water will contaminate the environment. On the other hand, the user must hold the wiping pad precisely between the pressing claws in order to achieve a satisfactory squeezing result.
  • a similar device is shown in CN 2 776 280Y , although here the pressing device is provided inside the bucket, but filling it almost completely.
  • a further embodiment of a wiping agent press is known.
  • the pressing device is also provided above the bucket opening.
  • a dipping area for dipping the cleaning agent into the bucket of water and for rinsing out the cleaning agent.
  • a handle is provided between this dipping area and the pressing device, via which the bucket can be lifted.
  • the handle for actuating the pressing device in the form of a foot pedal extends along the upper side edges of the bucket to the side of the bucket which, as seen from the pressing device, lies behind the dunking area.
  • pressing down with the foot is not easy.
  • a wiping agent can be squeezed out effectively with this device, it has the disadvantage that, on the one hand, the user has to raise his foot relatively far in order to be able to depress the foot pedal. Furthermore, on the other hand, there is the risk that the handle will become wet and soiled by the wiping agent hanging over it when the wiping agent is transferred from the rinsing area to the soaking area. Finally, due to the relatively high position of the foot pedal, higher tilting moments arise if the user does not load the foot pedal in the middle.
  • pressing devices which are arranged in a bucket and clamp and squeeze out a plate-like wiper covering as a wiping means by laterally displacing a press plate.
  • these pressing devices have the disadvantage that they are less suitable for hanging, non-plate-shaped wiper coverings, since the required pressing force cannot be applied homogeneously over the entire surface of the wiper covering if wrinkles form or the wiper covering is inserted in several layers.
  • the height of the insertion shaft must correspond to the width of the mop plate, which requires a comparatively high bucket.
  • the object of the invention is therefore to create a wiping agent press for wiping pads that can be detached from one side of a wiping plate in particular and then hang down freely and which has the most effective possible use of space in the bucket Allows squeezing out with little effort. Furthermore, the wiping agent press should protect the wiping agent and be easy to operate and inexpensive to produce.
  • a wiper press according to claim 1 .
  • the wiper press according to the invention is characterized in particular by the fact that the pressing mechanism comprises a lever mechanism which is coupled directly or indirectly to the bucket via a lever bearing, which is driven by the actuating means and is designed in such a way that when the actuating means is actuated in one pressing direction, the second pressing claw moves in Direction of the active press region of the first press claw is able to shift rotationally, with the displacement of the second press claw moving an active press region of the second press claw onto the active press region of the first press claw.
  • the second press claw can be rotatably mounted on the bucket, a cover of the upper area of the bucket or preferably on the first press claw. Furthermore, the second press claw can also be mounted in a guide which, in cooperation with the lever mechanism, enables a combination of a rotational movement with a translational movement of the second press claw in the direction of the pressing-active area of the first press claw.
  • Such storage can be formed, for example, by guide grooves with a corresponding shape or groove-like elongated holes.
  • the lever mechanism can also make it possible for the second press claw to perform a rotary movement in a first phase of movement, with a special bearing, for example in bearing journals, resulting in a release from the pivot bearing and then in a second Movement phase the lever mechanism causes a translational pressing movement of the second pressing claw by shifting the bearing journals within guide grooves that extend into the pivot bearing.
  • the second press claw can also be mounted floating on the bucket, in particular in the first press claw designed like a shell, with the claw pivot axis movable at an angle to the dipping direction.
  • the wiper can be squeezed out gently and effectively with little space requirement in the bucket, without major structural requirements.
  • a major advantage of the invention is that the lever-guided movement of the second press claw lowers this second press claw onto the first press claw in an optimal line of movement.
  • the lever mechanism means that a space-consuming arrangement of a guide carriage and a reversal of movement of the drive for the second press claw can be dispensed with, which not only optimizes the available interior space of the bucket, but also reduces production costs.
  • lever mechanism is designed as a toggle lever mechanism.
  • Such a toggle lever mechanism is characterized in that at the beginning of the movement a fast movement with low forces and towards the end of the movement of the second press claw a slower movement but with increased forces is possible. Due to the use of the toggle lever mechanism, the pressing chamber between the two pressing claws closes quickly at first without the maximum forces being able to be applied, with the lever effect of the then force-optimized arrangement of the levers relative to the force application points making a greater force available at a lower movement speed.
  • the invention achieves this through the design of the individual adjusting levers and the articulation of the drive lever of the lever mechanism.
  • the components are designed in such a way that a first adjusting lever is first rotated about one of its ends, while a second adjusting lever is essentially only displaced laterally. This is possible because the second pressing claw is mounted on the bucket accordingly.
  • first rotary movement of the first adjusting lever has largely been completed, further pulling down of a drive lever leaning against the connection between the first adjusting lever and the second adjusting lever leads almost completely to the lowering of the second pressing claw, i.e. the adjusting force in this area of the movement is almost completely in a pressing force is converted without force absorption by fixed components.
  • adjusting levers are arranged on both sides of the pressing claws, with a pair of first and second adjusting levers lying in one plane being provided on one side of the pressing claws and being connected to one another in an articulated manner.
  • This connection can take place directly, but a lever coupling can also be arranged between the two components, either as a pure bearing or as an intermediate force transmission rod or plate.
  • the drive lever in turn acts preferably either on the lever coupling or in the area of the connection between the adjusting levers on one of the two adjusting levers.
  • the drive lever is in turn connected directly to the adjusting means, which is preferably a foot pedal, so that the adjusting means can pull the drive lever downwards directly.
  • lever mechanism means that as a result there are two lever mechanisms that are coupled to one another in the cinematheque, which means that the pressing claws are evenly subjected to the actuating force on both sides.
  • this harmonious power transmission leads to a good pressing result and, on the other hand, it prevents the components from jamming and blocking.
  • the lever mechanism can also be arranged on the sides of the wall of the bucket.
  • spring means are preferably provided which hold the pressing claws in a defined, open initial position.
  • These spring means can be integrated into the lever mechanism, for example, and can be tensioned by the movement of the individual levers.
  • These can be traditional springs integrated into the articulated mounting of the levers or helical springs tensioned by the levers, which push the levers back into the starting position.
  • a wiping agent press according to the invention is shown in different positions of the pressing device to explain the function as an exemplary embodiment.
  • the wiper press consists of a bucket 1 and a pressing device arranged in the bucket 1 for a wiper covering used as a wiper, which for example hangs down on one side from a wiper plate of a wiper device and can be inserted into a press chamber delimited by a first press claw 3 and the second press claw 4.
  • a pressing claws 3, 4 are in an open position, this pressing space is open at the top and the first pressing claw 3 with its pressing-active, left-hand area is more like a receiving shell.
  • the wiping pad is loosened on one side of the wiping plate and the wiping plate is lowered over the handle of the wiping device into the wiping agent press.
  • the area above the pressing device is covered by a pressing area cover 11, which is placed on the rim of the bucket 1. So that the wiping agent can be threaded into the pressing device, the pressing area cover 11 has a passage opening which is located above the first pressing claw 3 .
  • the pressing device is activated via an external actuating means 2 in the form of a foot pedal, as a result of which the second press claw 4 moves towards the stationary first press claw 3 to form the pressing chamber.
  • the bucket wall has an upper area and a lower area.
  • the bucket 1 On the right-hand side, in the lower area, the bucket 1 is designed in such a way that along a vertical line drawn inwards approximately by the width of the foot pedal that forms the adjusting means 2 here Wall section the foot pedal is guided.
  • this constricted area is only provided directly in the area of the foot pedal; in front of and behind it, the wall of the bucket 1 also protrudes to the right in the lower area, so that parallel to the foot pedal forming the actuating means 2, a partial wall of the bucket is arranged at right angles to this vertical wall section Bucket's 1.
  • a groove is made here, in which the guide pins for guiding the actuating means 2, which can be seen in all three figures, are guided.
  • the actuating means 2 is connected in an articulated manner to the drive lever 7 of the lever mechanism 5 in the upper area.
  • the lever mechanism 5 is essentially formed here by 4 components: These are the first adjusting lever 8 and the second adjusting lever 9. These are connected via a lever coupling 10, which is best found in figure 3 can be seen, articulated with each other.
  • the drive lever 7 is also articulated to the lever coupling 10 in the area of the articulation of the first adjusting lever 8 .
  • the first adjusting lever 8 initially performs an almost complete pivoting movement when the pressing device is actuated.
  • the first adjusting lever 8 is pivotably mounted in the lever bearing 6 .
  • the lever bearing 6, in turn, is located on a side arm of the first press claw 3.
  • the lever coupling 10 or the arrangement of all components of the lever mechanism 5 are preferably designed in such a way that the lever mechanism 5 cannot roll over. Overturning in this context means that the actuating levers 8, 9 arranged in a V-shape with the opening pointing downwards are pivoted as the drive lever 7 is pulled down further until they are maximally aligned horizontally with one another, but do not pivot beyond that.
  • the outer ends of the adjusting levers 8.9 should therefore not protrude upwards in comparison to the lever coupling 10. This can either be ensured via the lever geometry, so that the turning over described above is not possible at all as a result of the previous closing of the pressing chamber, or it can be implemented via a stop provided in the lever coupling 10 . In both cases, the tensile force of the drive lever 7 can then be fully used to apply a pressing force.
  • the second press claw 4 is rotated by being mounted within the semicircular shape of the first press claw 3 , as a result of which the active pressing area of the second press claw 4 moves towards the active pressing area of the first press claw 3 .
  • This turning of the second press claw 4 is caused by the articulation of the second adjusting lever 9 on the second press claw 4 .
  • the position of the linkage is selected above the center of gravity or the resulting counterforce emanating from the clamped wiper means, so that the required tilting moment results.
  • the tines of the two press claws 3, 4 also interlock, resulting in additional guidance in the transverse direction.
  • the first pressing claw 3 is placed on the vertical wall section described above in the retracted, lower area of the wall of the bucket 1 .
  • the storage area for the first adjusting lever 8 is in turn provided outside of this part of the bucket 1 .
  • This arrangement has the particular advantage that the lever mechanism 5 transmits forces directly between the two pressing claws 3, 4, ie the wall of the bucket 1 is not loaded in the transverse direction by the pressing movement.
  • the lever mechanism 5 pushes the second press claw 4 in the direction of the active pressing area of the first press claw 3 .
  • This pressing area is characterized by prongs protruding upwards.
  • the second pressing claw 4 also has similar tines. This arrangement of prongs, which also extends into the area of the bottom of the pressing claws 3, 4, allows the wiping agent to be pressed while the liquid that is pressed out runs off at the same time.
  • the bucket 1 In the lower area, on which the adjusting means 2 is movably mounted, the bucket 1 has the adjusting means mounting for the foot pedal.
  • the upper area of the bucket 1 protrudes beyond the lower area in this area, the protruding area being open at the bottom and the first press claw 3 being plugged or placed onto the wall of the lower area of the bucket 1 in the protruding area.
  • the drive lever 7 is guided through the open bottom, protruding part of the upper area of the bucket 1.
  • the wall of the upper area of the bucket 1 encloses the first press claw 4 in the lateral direction almost completely to form a splash guard in the horizontal direction.
  • the upper area of the bucket 1 covers at least 70% of the actuating means 2 designed as a foot pedal. Preferably, the coverage will be 90% or even 100%, with a slight visibility of the foot pedal for easier operation can be quite useful.
