  Such types of floor wiping devices are known. The floor wiping device is particularly preferably used for water washing of hard flooring, such as tiled floors or flat soil floors, in the home area. For this purpose, the floor wiping device has a floor cleaning element which acts on the floor, for example a floor cleaning element in the form of a wiping element, for example made of textile material, as is known.

  With respect to the above prior art, the object of the present invention is to further improve a floor wiping device of this type, in particular with regard to operation in the operation of the floor wiping device.

  A possible solution to the problem is given by the first inventive concept in which, in a floor wiping device, the rocking body is considered to be controlled by a guide element with respect to the rocking movement. By using this guide element, an acute angle of the longitudinal central axis of the oscillating body with respect to the basic position of the oscillating body, in particular at one terminal movement position formed by the eccentric drive, An acute angle with respect to the basic position of the swinging body whose vertical axis is centered preferably in a direction perpendicular to the normal movement direction of the floor wiping device or in the direction of movement of the floor wiping device, or the other of the swinging body It has been achieved that this acute angle at the end position of the lens does not exceed a predetermined magnitude. Correspondingly, the centering of the vertical axis of the swinging body during swinging preferably changes only within a certain tolerance in the centering, more preferably without tolerance, so that the total motion of the swinging body A favorable parallel centering is always provided over the stroke. This provides improved operation of the floor wiper in operation of the floor wiper. In particular, when the eccentric drive device is switched on to act on the swinging body, the force consumed by the push-pull movement of the floor wiping device is minimized by this configuration and the operation of the floor wiping device Can be easily controlled by the user correspondingly.

  In the following, other features of the invention are also described in the description of the figures, often in the preferred context of the subject matter of claim 1 or other claim features. However, they also have meaning in the context of claim 1 or each individual feature of each other claim only, or may each have meaning independently.

  The proposed guide element for controlling the oscillating movement of the oscillating body is formed by one or more elastomer layers, membranes, coil springs or leaf springs which are connected not only to the oscillating body but also to the fixed part. May be. Furthermore, in this connection, rod supports made of plastic or metal that can be elastically deformed for a sufficient rod length can also be used. In this regard, an arrangement is also possible in which a plurality of inner holes are provided in the oscillating body, and one roller each fixed to the fixing part rolls on the surface of these inner holes. These rollers may be arranged in the rocking body so as to cooperate with the wall of the inner hole provided in the fixed part.

  In a preferred embodiment, the guide element is composed of a swinging body link and a fixed part link, which are coupled to each other and to the fixed part and the swinging body, and in this case, more particularly, each hinge shaft The swinging body link is centered in a direction perpendicular to the planar extension direction of the swinging body, and the swinging body link is hinged to the swinging body and the fixed part link is hinged to the fixed part. Preferably, the oscillating body link and the fixed part link are connected not only between each other, but also to the fixed part or the oscillating body, in particular so as to be capable of rotational movement. For this purpose, a link device is advantageously used.

  It is preferred that the guide element or in particular the oscillating body link and / or the fixed part link described above does not always carry out a complete circular movement but only a oscillating reciprocating movement. This is a rotational movement between each slight angle. This may be, for example, 5-25 ° with respect to the central position in the motion plane of the rocking body.

  In this case, a fixed point or a rotation point between the swinging main body links or between the fixed part links forms a preferable interval with each other in the longitudinal extension direction of the swinging main body, so that the two swinging main body links and the fixed part links are respectively provided. It is further preferable that an arrangement is made in which the oscillating body or the fixed part is coupled to be rotatable. In a preferred form, in particular, this spacing of the hinge points in the swing body of the swing body link and / or the hinge points in the fixed part of the fixed part link is 1 / 4-1 / 3 of the longitudinal extension length of the swing body. More preferably, it takes a value approximately half of the longitudinal extension length.

  It is preferable that the longitudinal center axis of the swinging body extends in the transverse direction with respect to the normal movement direction of the apparatus.

  It is further preferred that the coupling link provides a coupling between the oscillating body link and the fixed part link for a preferred parallel guide of the oscillating body that oscillates generally circularly due to the eccentric action. Thereby, a parallel link device is preferably provided, in which case, in a preferred longitudinal rectangular shape of the oscillating body parallel to the longitudinal edge, at least one longitudinal central axis of the coupling link is oscillated. More preferably, it is centered parallel to the longitudinal central axis of the body.

  In a preferred form, an oscillating body link extending from the coupling link to the oscillating body and / or a stationary part link extending from the coupling link to the stationary part is coupled to the coupling link via a rotary joint, thereby preferably A link adapted to swing motion of the swing body within the swing body surface or a plane extending parallel to the swing body surface while the vertical axis of the swing body is always centered within a predetermined tolerance. The following movement is preferably achieved as a whole. In this regard, the longitudinal axis of the oscillating body can always be centered in parallel at each of the different oscillating positions of the oscillating body, while preferably allowing a sufficiently large oscillating circle diameter of the oscillating body. preferable.

  In another preferred embodiment, the interval in the longitudinal extension direction of the oscillating body link between the coupling portion of the oscillating body link and the oscillating body is such that the coupling portion of the oscillating body link with the oscillating body is Is designed to be greater than the vertical spacing between the connecting links extending parallel to the longitudinal axis of the. That is, the interval between the coupling portion of the swinging body link and the swinging body link is the interval between the connecting portion of the swinging body link and the coupling link and the coupling link when viewed in a direction perpendicular to the coupling link. More preferably, it corresponds to approximately 2 to 10 times, more preferably 5 to 6 times. It is further preferred that such a spacing value is also set for the fixed part link in an alternative manner or in combination therewith, in this case the oscillating body between the coupling part of the fixed part link with the fixed part The distance in the longitudinal extension direction of the fixed part link is greater than the vertical distance between the connecting part in the fixed part of the fixed part link and the connecting link extending parallel to the longitudinal axis of the swinging body.

  Furthermore, it is preferred that the same pair of oscillating body links and stationary part links extending from the oscillating body to the coupling link and from the coupling link to the stationary part are arranged crossing each other. Thereby, the arrangement of the links that reduces the structural space while achieving a larger swing circle of the swing body is achieved. In this connection, the hinge in the coupling link of the oscillating body link extending from the oscillating body to the coupling link as viewed from the direction of the hinge in the oscillating body of the oscillating body link is more preferably It can be seen that it is further advantageous to arrange in a direction parallel to the axis, preferably farther than the hinge of the fixed part link between the fixed part and the coupling link. Correspondingly, with respect to the coupling link, in particular with regard to at least one position of the oscillating body, the hinge of the oscillating body link is preferably extended parallel to the longitudinal axis of the oscillating body. In addition, it is preferable that the fixed part link is arranged closer to the hinge in the connecting link.

  In order to avoid an undesirably extended posture of the parallel link device, the coupling between the swing shaft of the first swing body link extending from the swing body to the coupling link and the first swing body link On the coupling line between the hinge axis of the link and the coupling axis between the hinge axis of the coupling link of the second oscillating body link and the hinge axis of the oscillating body of the first oscillating body link. It is further preferable that the distance formed is designed to be as large as possible. In this case, it is preferable that the distance be 1 / 10-1 / 3, more preferably 1/4, of the length of the swinging body link between the hinge shafts of the swinging body link.

  The distances between the hinge shafts in the swing body of the swing body link, between the hinge shafts in the fixed portion of the fixed part link, and between the hinge shafts in the joint link of the fixed part link, more preferably the link of the swing body link It can be seen that a further preferred form is advantageous in that the spacing between the hinge axes in is also the same. As a result, a parallelogram for guiding the oscillating body is formed. Therefore, the oscillating body is preferably always guided parallel to the fixed part during the circular oscillating motion. . In order to keep the wear small, it is further preferred that the arrangement of the respective hinge points or rotation points is selected so that the swing angle of the individual links in the rotary joint is as small as possible.

  More preferably, the swinging body link and the fixed part link are arranged such that the rotation direction of one swinging body link and the rotation direction of the other fixed part link are the same. That is, correspondingly, in the oscillating circular motion of the oscillating body, the oscillating body link and the fixed portion link are always oscillated in common clockwise or counterclockwise with respect to their rotational axes. Preferably, in this case, the rotational movement of the other links takes place simultaneously and synchronously through the use of a coupling link.

  Preferably, the oscillating body link and / or the fixed part link and / or the coupling link are flat parts having a surface extension substantially parallel to the oscillating surface. In a preferred form, this reduces the structural height in the form of a link device used for guiding the rocking body. In this case, the oscillating body link and / or the fixed part link and / or the connecting link may be made of a metal material or a hard plastic material.

  In a preferred form, the link has a sliding bearing in the area of the rotational coupling, and it is further preferred that the sliding bearing is plastic injection molded on the link portion attached to the rotary joint. In this bearing, it is preferable that the pin is rotatably supported, and it is more preferable that the pin is press-fitted into the swinging body or the fixed portion and is coupled to the respective links by butt contact. As an alternative, the pin may be fixedly coupled to the link and rotatably supported in the rocking body or fixed part.

  Instead of the multi-part system of the parallel link device described above, in one variant, the rocking body link is formed continuously and integrally with the fixed part link and / or the rocking body link and / or Alternatively, it may be designed such that the fixed part link is integrally formed with the coupling link. Correspondingly, more particularly in the form of such a monolithic part as a plastic injection-moulded part, both pairs of oscillating body links and fixed part links are integral with the coupling link, ie as a single part and It is preferable that they are mutually bonded with the same material. As an alternative, a single part system is also conceivable in which the rocking body link is connected to the fixed part link and / or the rocking body link and / or the fixed part link is connected to the coupling link via a metal spring element. More preferably, the metal spring elements are joined together by injection molding of the link material within this process, especially in the form of links in the plastic injection molding process.

In the case of a single part configuration, this metal spring element forms a thin-walled part to form the hinge region. Especially in the case of a single part identical material form in the form of a plastic injection molded part, this thin part is formed by thinning the material in the hinge region.

  In the case of a single part form, in one form, for example, a pin form integrally formed with the link as a single part, wherein the pin is fitted into the corresponding bore of the rocking body and / or the fixed part and / or the coupling link Hinge region between the swing body link and the swing body and / or between the fixed part link and the fixed part and / or between the swing body link and / or the fixed part link and the coupling link. However, it is formed to be capable of rotating. In a single part configuration, it is further preferred that the hinge region is formed so as not to rotate relative to the stationary part and / or the swing body. This is achieved, for example, by making the cross-section of the hinge part, in particular the one or more hinge parts integrally formed on the link, non-round. In this case, the link mobility required for the preferred parallel guidance of the rocking body is preferably provided by a thin-walled part or an embedded spring element. In this case, the hinge axis in the non-rotatable hinge region is assumed to be half the thin part, as viewed in the longitudinal direction of the swinging body link and / or the fixed part link and / or the connecting link, where The hinge shaft formed between the deflections in the region of the part moves slightly along the thin part as a function of the bending radius formed by the deflection of the attached link, so that the two end positions of the rocking body Between, it will be formed in the different position in the area | region of a thin part.

  Preferably, the width of the thin portion measured transverse to the longitudinal direction corresponds to 1 / 10-1 / 3 of the maximum width of the oscillating body link and / or the fixed portion link and / or the coupling link, In this case, it is further preferable that the width of the thin portion is clearly increased on both sides in the longitudinal extension direction of the link, that is, in particular, the width of the thin portion is increased by 3 to 10 times.

  In a variant, in particular the proposed arrangement of the guide elements of the parallel link device is preferably carried out in the plan view attached to at least one longitudinal edge of the oblong rectangular rocking body, both longitudinal edges More preferably, it is carried out as an attachment. The proposed method further reduces manufacturing tolerances without increasing vibration.

  Furthermore, the invention relates to a main body, in particular a disc-shaped main body, which is driven to swing relative to a fixed part, whose swinging motion is controlled by a guide element.

  Such types of bodies, in particular oscillating bodies, are known. This is used in particular for electrically operated equipment, for example for finishing or maintenance of hard surfaces, and for example in the form of floor cleaners or floor maintenance equipment, such as in particular floor polishers or floor wipers. The In this case, the disk-shaped body with a circular rocking motion, preferably having a vertically long rectangular plan view, and alternatively having a vertically long oval or circular plan view, is actuated via an eccentric drive, Operated on the surface to be maintained or finished.

  With respect to the above prior art, the technical problem of the present invention is to further improve this type of oscillating body, in particular with respect to the controlled guidance of the oscillating body.

  A possible solution to this problem is given by the first inventive idea considering the links connected to the body, which are connected to each other and to the fixing part on the other hand on the other hand. In a preferred form, these links are connected to each other and to the body being driven in a swinging manner, as well as to a fixed part, in the form of a parallel link device, in a rotationally movable manner. This leads to a preferred parallel guide of the body relative to the preferred longitudinal central axis of the body, more preferably relative to the attached longitudinal edge of the fixed part, in this case The formed guide element allows a large oscillating circle diameter and only requires a small structural space. With respect to supplementary or alternative features with respect to the guide element attached to the swing-driven body, the same features as described above with respect to the floor wiping device apply in relation to the claims. The swing driven main body is preferably the swing main body of the floor wiping device. In this case, the link coupled to the main body further includes the swing main body link coupled to the swing main body, and the fixed portion. A coupling link that couples the fixed part link and the swinging body link to each other and preferably the fixed part link to each other, the coupling link being centered parallel to the longitudinal central axis of the body It is preferable.

It is guided so as to extend in a plane parallel to the surface (floor surface) to be maintained. Correspondingly, the rocking body 6 is preferably centered in a horizontal plane in the operating position of the floor wiping device 1 and more particularly with respect to the mounting surface 10. The repetitive rocking motion of the rocking body 6 is performed in this plane.

  A guide element 18 is provided for controlled swing movement of the swing body 6. This guide element 18 is preferably included in a link device 19, in particular a parallel link device.

FIGS. 8 and 9 show an alternative embodiment which is formed in one piece in a continuous manner, and correspondingly, preferably a single part linkage 19 made of the same material is formed.

  The linking device 19 essentially consists of two pairs of oscillating body links 20, 20 ′ and fixed part links 21 and 21 ′ spaced apart from each other in the longitudinal extension direction of the oscillating body 6. In this case, these pairs are further coupled via a coupling link 22 that extends substantially parallel to the longitudinal axis x.
