Technical area

The invention relates to a wing mop, comprising a support body which is formed by a double joint and two wing plates, which are arranged in the longitudinal direction of the support body on both sides of the double joint and connected thereto, and a stem, wherein the support body on the stem axially facing away from a side The size of the support body substantially corresponding wiper pad and wherein the wing plates are pressed by means of a squeezing against each other, wherein the squeezing device is fork-shaped and formed on the stem axially facing away from the side and two substantially parallel to each other and for folding the wing plates to the double joint comprising pressure arms engageable with the wing panels, the ejector being connected to the stem, and wherein the stem is pivotally connected to the double joint at least about the longitudinal axis of the support body. State of the art

Such a wing mop is known from EP 1 208 788 B1. The prior art wing mop is provided for cleaning planer surfaces, wherein the stem is pivotally mounted on the double joint. On the stem a sliding sleeve is mounted axially movable in the direction of the stem, wherein the known mophead guide means on the wing plates and / or in the pressure arms for the defined folding of the wing plates by means of the pressure arms. Through the gimbal mobility of the

Double joint opposite the stem can be cleaned well in the main wiping even under low furniture.

The sliding sleeve is composed of a handle portion, a sliding portion with a guide slot and the fork-shaped molded pressure arms together. When operating the sliding sleeve is to be noted, however, that a total of large forces must be expended to press the wing plates against each other and thereby express the wiper pad. The forces to be applied are all the higher, the stiffer the material that makes up the wiper pad. In particular, when the handle part of the sliding sleeve is moist and thereby soggy, is the

Handling of the aforementioned mophouse significantly more difficult and no longer satisfactory.

From DE-AS 1 293 983 a cleaning device is known, with attached to a holder cleaning tool, such as a sponge, and means for expressing the cleaning tool. The device consists of a connected to a device handle forked roll holder with two parallel rows of rollers, an actuating rod which is displaceable by means of a handle on the device handle in the direction of the device handle and at its lower end the roll holder receives. The operating rod pulls the cleaning tool when squeezed between the rollers. The cleaning tool is formed in particular by a sponge having a circular arc-shaped surface of more than 180 °. The device handle and the cleaning tool are rigid, that is non-angularly movable, interconnected; An angular mobility of the device handle relative to the cleaning tool is not provided. In particular, for cleaning tools that have no circular arc-shaped but a flat wiping surface, such as a wiper pad that is used in wing mops, such a rigid assignment is not very satisfactory, because optimal cleaning of the planar surface to be cleaned is only possible if the flat Wiper pad just flies on the surface. During use of a cleaning device, the user is hardly able to ensure this optimum assignment with a rigid assignment of handle to cleaning tool. Even small changes in the angular position of the stem relative to the surface to be cleaned cause disadvantageous use properties and deteriorated cleaning results in such cleaning devices.

Presentation of the invention

The invention has for its object to further develop a wing mop of the type mentioned in that the expressing easier, that is, with less effort to operate, and thereby the risk of injury to the user is reduced, even if he has wet hands and / or the wing mop is damp and soggy.

This object is achieved by the features of claim 1. In advantageous embodiments, the dependent claims relate. To achieve the object, it is provided that the ejection device has an axially movable in the direction of the handle actuating rod, which is frontally connected on the one hand with the double joint and the front side with a fixedly attached to the stem, pivotal handle for actuating the squeezing device. It is advantageous that the operation of the expressing device can be done very easily and safely. To press against each other of the wing panels, which may either be occupied by a common wiper pad or each of which may be provided with a wiper pad, the user holds in one hand the handle and the other hand of the user encloses the handle. The handle can be designed either as a knob or preferably annular. Subsequently, the handle is pivoted in the direction of the upper end of the stem, which is hervorzuhebendem advantage that the handle is fixed relatively stationary on the stem. As a result, the handling is simplified because unwanted relative movements in the axial direction between the handle and the stem are avoided. Even if the user's handgrip and / or hand are wet and soggy, the wing mop can be securely squeezed out without the risk of the user slipping off the handle and possibly being injured. The combination described in claim 1 of a handle which is pivotally connected at least to the longitudinal axis of the support body with the double joint to clean, for example, easily under low furniture and surfaces in the form of an 8 and a fixedly attached to the handle, swivel handle Actuation of the squeezing, found in the previously known state of the art no role model; the handling of the wing mop is simple and safe, the cleaning result, even in hard to reach places, good.

It is preferably provided that the actuating rod extends substantially in the stem. On the one hand, the actuating rod is characterized by external Protected influences, so that undesirable deformation of the actuating rod and the resulting impairment of the performance characteristics of the expression is excluded. On the other hand, the stem does not unnecessarily have many protruding parts where the user could get caught and possibly injured.

Further improved performance characteristics with respect to the cleaning performance of the wing mop can be achieved in that the stem is connected cardanically movable with the double joint. The handling of the

Wing mops for cleaning e.g. difficult to reach places under furniture, this is further simplified.

The wing panels can each be connected to the double joint by means of a spring and against the spring force of the springs when pressing the squeezing against each other be pressed. The springs can be designed as hairpin springs and be attached to the double joint, that the springs cause not only a plane-parallel alignment of the previously pressed against each other wing plates to be cleaned surface following the Ausdrückvorgang. Such, spring-assisted automatic plane-parallel alignment of the wing panels to be cleaned surface is particularly advantageous when a wiper pad is used, which has only a lower restoring force in the direction of flatness following the Ausdrückvorgang. Without the support of the spring force, the wing plates would still be arranged at an angle to each other following the squeezing process and would only rest plane-parallel on the surface to be cleaned when the user places the wing mop on the surface to be cleaned. The springs can also cause the wing plates following the Ausdrückvorgang align in such a way to the stem that an immediate further wipe the surface to be cleaned is possible. For example, the wing plates, due to the spring force, automatically tilted at an angle of 20 to 30 °, based on the vertical assignment to the stem, align.

Even during use of the wing mop, the springs have an advantageous effect on the performance characteristics. The movement of the stem, in particular about the longitudinal axis of the support body, is damped by the springs. Wiping pads with high cross section, which thereby during the

Use unstable, as wiping pads tend with low cross section and tilting would be difficult to control without the damping of the movement of the support body relative to the stem. The cleaning result would be affected.

The ejection device may be provided with a coupling for receiving a replaceable abrasive body. The coupling and the scouring body fixed thereto can enclose an angle of substantially 90 ° with the wiper pad. The scrubbing body can consist of different materials. For example, there is the possibility that the scrubbing body consists of a sponge, which has a more abrasive behavior, as the wiper pad. According to another embodiment of the scouring body may comprise bristles which consist of a polymeric or elastomeric material, whereby a combination of the aforementioned embodiments / materials, depending on the particular application, may be useful. The combination of wiper pad and scouring body is particularly advantageous if the surfaces to be cleaned have strong impurities that would be difficult to remove alone with the wiper pad. In such a case, the user would first use the scrubbing body of the heavy contaminants solve the surface to be cleaned to then pick up the dissolved impurities with the wiper pad and eliminate. These two operations could be done with one and the same muffler.

The pressure arms may have on their sides facing each other axially in the direction of the stem extending guide grooves which can be brought into engagement with each of a guide cam of each wing plate in engagement. Due to the design and arrangement of guide and guide cams a squeezing of the wiper pad without jamming and jamming of the merged parts is possible. In addition, regardless of the angle they have previously assumed relative to the stem, the leaflets and the double joint are directed substantially perpendicular to the stem before the leaflets are actuated by actuation of the handle by means of the actuating rod between them

Pressure arms of the squeezing device are pulled; an alignment by hand before the Ausdrückvorgang is unnecessary.

If the two wing plates fastened to the double joint have a great length, it is advantageous to ensure increased contact pressure on the pressure arms in the region of the ends of the wing plates facing away from the double joint, in order to obtain a well-expressed wiper pad in the region of the ends. For this purpose, it may be provided that each wing plate on its side facing away from the wiper pad has a rising from the double joint in the longitudinal direction of the support body in height ramp for continuously increasing the pressing force during the Andrückvorgangs. The user can individually decide by means of such a ramp whether the wiper pad should be more or less expressed. If necessary, the wiper pad is also well expressed on the side facing away from the double joint. Brief description of the drawing

Embodiment of the invention

In FIG. 1 and in FIGS. 2 to 13, an embodiment of the wing mop according to the invention is shown. The wing mop comprises a support body 1 made of a polymeric material, which consists of a centrally arranged double joint 2, wherein in the longitudinal direction 5 of the support body 1 on both sides of the double joint 2 in each case a wing plate 3, 4 is connected. The double joint 2 and the two wing plates 3, 4 are such connected to each other, that upon actuation of the squeezing device 8, the two wing plates 3, 4, based on the double joint 2, each can fold down. The support body 1 has on the stem 6 axially facing away from a one-piece wiper pad 7, which corresponds to the size of the support body 1 and is formed as a sponge.

Instead of the one-piece wiper pad 7 shown here, there is the possibility that a multi-part wiper pad is used, for example, a two-part, each part then, for example, the size of a wing plate 3, 4 corresponds. On each wing plate 3, 4 acts in each case a pressure arm 9, 10 of the

Expressing device 8, which is fork-shaped and open on the side facing away from the handle 6. The ejection device 8 is fixedly connected to the stem 6, wherein the stem 6 is pivotally connected to the double joint 2 about the longitudinal axis 5 of the support body 1. The connection between the stem 6, on which the squeezing device 8 is arranged, and the support body 1 is achieved by an actuating rod 11, which is axially movable in the direction of the handle 6. The actuating rod 11 is frontally connected on the one hand with the double joint 2 and the front side on the other hand with the handle 12 which is fixed, but pivotally mounted on the handle 6. By the handle 12, the squeezing device 8 is actuated. By such a construction, the squeezing device 8 is easy and easy to handle even when the user's hands and / or the handle 12 are wet and / or soggy. As can be seen in Figures 1, 2, 4 to 6 and 9 to 13, the actuating rod 11, except for its front ends in the region of the double joint 2 and the handle 12, in the interior of the stem 6, so that the actuating rod before unwanted external influences and resulting damage is protected. The wing plates 3, 4 can on their side facing away from the wiper pad 7 S. 1 of the double joint 2 in the longitudinal direction 5 of the support body 1 outwardly in height elevating ramp 22, 23 for continuously increasing the pressing force during the Ausdrückvorgangs have.

FIG. 2 shows an enlarged illustration of the wiping head from FIG. At the existing of a polymeric material expressing device 8, a clutch 15 is provided for receiving a replaceable abrasive body 16, wherein the clutch 15 and the scouring body 16 are non-positively and / or positively connected. Preferably, a positive connection, for example in the form of a dovetail black is used. As a result, a used scouring body 16 can be released, if necessary, with little effort from the coupling 15 and replaced by a new scouring body 16. Based on the wiper pad 7, the scouring body 16 is arranged at an angle 17 of 90 ° thereto. The combination of wiper pad 7 and scouring body 16, summarized in a wing mop, is particularly advantageous when first strong impurities dissolved by the scouring body 16 of the surface to be cleaned and these dissolved impurities are then taken up by wiper pad 7 and then removed.

The scrubbing body 16 comprises a plurality of bristles in the example shown here.

In Figure 3, the mop head of Figure 2 is shown from behind. The attachment of the

Wischpads 7 on the support body 1 takes place in the here shown

Embodiment by a hook and loop fastener 24 through which the wiper pad

7 is connected to the two wing plates 3, 4.

Compared to the representation of Figure 2, the stem 6 is tilted from Figure 3 about the longitudinal axis 5 of the support body 1 to the rear. FIG. 4 shows the mopping head from FIG. 2 with the scouring body 16 removed. The coupling 15 is dovetail-shaped.

FIGS. 5 and 6 each show a view of the carrier body 1 without a wiper pad 7 from below. It can be seen that the two wing plates 3, 4 are connected to the double joint 2 in each case by means of a spring 13, 14 and against the spring force of the springs 13, 14 upon pressing the squeezing device 8 are pressed against each other. The springs 13, 14 are designed as hairpin springs and also cause by their arrangement that the movement of the stem 6 is "damped" about the longitudinal axis 5 of the support body 1. Thereby unwanted and difficult to control tilting movements of the support body 1 relative to the handle 6 significantly reduced, so that the handling of the wing mop is significantly improved overall, especially if the wiper pad 7 has a high cross-section and thus is very compliant overall.

In FIGS. 7 and 8, sections of the operating state according to FIGS. 5 and 6 are shown. In Figure 7, the guide cam 20, 21 of the wing plates 3, 4 in the

Guide grooves 18, 19 positioned in the lower area. The ejection device 8 with its pressure arms 9, 10 is inclined to the vertical and shows the position that the wing mop usually occupies during the cleaning of flat surfaces. By the flats 25, 26 of the guide cam 20, 21 and the likewise flattened respective insertion bevels 27, 28 of the guide grooves 18, 19, an undesirable shift is excluded. In Figure 8, the squeezing device 8 is moved together with their pressure arms 9, 10 for expressing the wiping pad 7 relative to the support body 1 in the vertical. During the Ausdrückvorgangs the guide cam 20, 21 push into the guide grooves 18, 19th In FIGS. 9 to 13, the expressing process is shown in a chronological sequence, the wiping pad 7 and the scouring body 16 not being shown for ease of understanding. FIG. 9 shows the wing mop according to the invention during the intended use when cleaning flat surfaces. The wing plates 3, 4 and the double joint 2 lie in one plane. In Figure 10, the handle 12 (see Figure 1) is pivoted about a hinge which is fixedly connected to the stem 6, upwards. During the pivoting of the handle 12 upwards also moves the actuating rod 11, which is axially connected on the one hand with the handle 12 and axially on the other hand with the double joint 2, also upwards, thereby takes the double joint 2, wherein the wing plates 3, 4 relative are bent down and the guide cam 20, 21 of the wing plates 3, 4 in the guide grooves 18, 19 of the pressure arms 9, 10 of the squeezing device 8 thread.

In FIGS. 11 to 13, the handle 12 is folded further and further upwards from its position shown in FIG. 1 until the position of the wing plates 3, 4, referred to the ejection device 8, shown in FIG. 13 has been reached. If the wing plates 3, 4 provided with a wiper pad 7, this would now be expressed.

Subsequently, the lever 12 shown in Figure 1 is returned to the position shown in Figure 1, wherein the wing plates 3, 4 and the double joint 2 from the position shown in Figure 13 on the positions of Figures 12 to 10 in the position as shown in FIG 9, moved back.
