    description
    The invention relates to a device for leveling and / or removing covered with free-flowing or pasty materials soils, especially tennis courts, the device consists essentially of a fastened to a towing leveling and / or peeling.
    State of the art
    After each game of tennis is usually the tennis court, which consists of clay on a solid pre-prepared ground, withdrawn with a device. The device consists of a leveling and / or stripping element attached to a towing element, wherein the towing element is a rope that can be gripped by hand and the leveling and / or stripping element is a trawl device. This trawl device, consisting of a network of ropes, serves to remove accumulations of clay and spread this more or less well.
    From DE 8 517 667 U a development is known, which should cause a good leveling of the tennis court due to a special trawl training.
    All configurations of such devices with a trawl are suitable for leveling the place again, especially after a game of tennis. Greater unevenness, stronger accumulations, holes or the like are not or only insufficiently eliminated. Thus, they adapt to the respective large-scale elevations or depressions or depressions on the square relatively and are not removed or fill depressions not enough with material. The sinks or hollows are recognizable by heavy downpours on most tennis courts due to standing puddles. During the time of use of tennis courts resulting troughs are then virtually not leveled, since the uniaxial geometry does not promote or ensure a level filling with clay in the handling. For the same reason, these devices are also only partially effective and can be used for the early season of tennis courts.
    From DE 20 303 292 a device for leveling of a raised material on a band material is known. In particular, in riding arenas there is the problem that material is thrown on the edge of a riding track, which must be removed with blades. For this purpose, DE 20 303 292 proposes a towing device which removes the thrown up material from the gang in a puff-like manner and distributes it evenly. To do this, a transverse sheet with a convex curvature is provided which digs the material away from the band and spreads over the arched sheet. Excess material enters a collecting bag located behind the sheet, which then carries out the further distribution of the material.
    From DE 20 205 003 053 U1 a device for the repair of tennis courts is known. The device consists of a drawbar with a frame, on the underside of an obliquely extending scraper element is arranged. This scraper element is static and arranged at a certain angle to the pulling direction. So that the scraper element engages in the sand of the tennis court, the entire device is formed with metal runners, which allow a tow over the sand of the tennis court.
    However, since the device always has the constant width, it is necessary in particular in tight places to raise the device, erect edgewise and pass through the narrow places. In addition, the device - if this must be kept - very unwieldy.
    If a tennis court has bumps, it is necessary to use heavier equipment. Thus, for example, a device known from the prior art in the design of a peeling planer (DE 10 013 647 A1) is suitable for eliminating roughing. A major disadvantage of this device, however, is that it is very heavy, bulky and can only be used by trained personnel with respect to their weight. In addition, the device is very expensive to buy and can not be purchased by many tennis clubs.
    Object of the invention
    The object of the invention is to achieve a relatively flat floor surface, especially in tennis courts, in a very simple and cost-effective manner.
    Solution of the task
    The object of the invention is solved by the features of claim 1.
    Advantages of the device
    The object is achieved by a special device which has substantially at least one transverse profile element in function of a peel-off rail. The cross profile element is attached at its two free ends to sliding supports, which take on a carriage-like function. Furthermore, a towing element is provided, which makes it possible to pull the device according to the invention by hand. By dragging this device, a spreading or scrape or removal is achieved.
    The transverse profile element is connected in each case at its ends to the sliding supports, wherein the surface of the sliding supports is advantageously flush with the lower edge of the transverse profile element. This creates a distance from the lower edge of the transverse profile element to the ground to be processed. This distance corresponds in this embodiment, the thickness of the sliding support. The towing element is connected at a favorable wide angle (relative to the center of drag) on the outside of the device, advantageously on the sliding supports, whereby the device can be better performed when towing / pulling.
    By dragging / pulling the device over a possibly loose loose floor covering is described by the low-flat or almost floating edition of the sliding supports on the substrate to be processed, the cross-sectional element in function of a peel rail only on higher ground surveys on these two support points Sliding supports move or remove the brick dust, and this excess material is automatically distributed by the pulling movement in existing depressions or hollows. Due to the fact that the transverse profile element is spaced from the ends of the respective sliding profiles (for example in the middle) and in one embodiment the angle profiles extend in the direction of the longitudinal extent of the sliding supports, a kind of storage space is created between the angle profiles of the sliding supports and the transverse profile element. In this storage space, excess material, whether it is trapped or dry, can be "stored" as in the formation of a funnel during towing. This material is then discharged successively during the pulling or towing process through the gap which exists between the cross-sectional element and the ground. The height of the cross profile element and the angle profiles are decisive for the amount of material that is carried along in this storage space. Each repetition of the process thus leads to a better result.
    In addition, there is the advantage that in particular after the flooding of the floor to be leveled due to the arrangement of the or the cross-sectional elements, the water located in the soil is sucked out. The corresponding weight of the device supports this process. As a result, an optimal compression and distribution of the free-flowing material can be achieved.
    A further embodiment of the device provides for providing a plurality of transverse profile elements, which are preferably arranged parallel to one another (in the direction of traction behind one another). A special design can provide that they are arranged at a different distance from the ground, so that the first cross-sectional element (seen in the towing direction) eliminates coarse clusters, while the second and possibly further level processes the finer clusters. A development may also provide that the cross-sectional element is adjustable in height to the appropriate needs, so that the height is variably adjustable. When using a plurality of transverse profile elements, a cascade-like arrangement with respect to the distance to the floor to be leveled can be provided.
    A further development can also provide that in addition to the side facing away in towing direction a trawl is arranged.
    In order to provide a structurally stable embodiment, it is necessary to arrange a stabilizing rod in addition to the transverse profile element parallel to this. This stabilizing rod is preferably fastened with angular elements on the sliding support. Thus, the load on the respective fixing points of the transverse profile element is reduced with the sliding supports.
    In order to enable the transport of such a device in a conventional passenger car (PKW), it is provided to make the fixing points of the transverse profile element and the stabilization bar detachable.
    The device according to the invention provides for the transverse profile element and the stabilizing rod also to be connected via joints, hinges or equivalent functional elements. This creates a parallelogram-like structure that can be achieved in a very simple manner by different handling of the towing element.
    This training has several advantages. On the one hand, this makes it possible to design the cross-sectional element very broadly, in order to achieve a higher efficiency (relative to the time) of the peeling. In addition, it is possible to pass in narrow places, such as in the area of the net posts, and to work on the other half of the square. This is achieved in that by pulling on the towline - for example, on one side and not centered - a shift occurs, such that the sliding supports are offset from one another and thereby - seen in plan view - a shifted parallelogram.
    Another advantage is that due to the arrangement of the device can be effected that the distribution is not uniform, but reinforced to one side. Due to the geometry of a parallelogram, a better scraping or erosive effect on the ground can be achieved during the axial displacement, and the excess material in front of the defined peel-off rail can be directed to a desired side in the pulling direction of the device. A presetting of such an arrangement is not necessary, since this is achieved only by embracing the towing element (off-center). Then, such a parallelogram automatically adjusts itself.
    The provided linkages of the or the transverse profile elements can be configured in different ways. As a hinge means hinges may be provided, which operate like a door. To facilitate transport, the bolts of the hinges can be removed. To avoid losing the bolts, they are secured with a split pin or spring pin or equivalent.
    To provide the sliding supports on the outside corners with a rounding or bevel, avoids the attachment of the device to fences and nets in the leveling work.
    To provide the cross profile element in function of Abziehschienen with a straight, wavy or serrated Abziehklinge is also beneficial and allows a later replacement of the blades at excessive wear.
    The expression of the stabilizing rod and / or the transverse profile element as a one-piece or multi-part L, U or T profile in its open or closed cross-section is vibration-resistant and dampens vibrations occurring. In addition, it increases the statics of bending loads. The vibration inhibition and the increased static can also be achieved by a fixed or articulated interconnection of cross bar to cross bar. A different height or a height adjustment of the lower edge of the blade or the lower edge of the transverse profile element in function of a peel-off to the sliding supports is conceivable.
    As a trailing element advantageously a rope is chosen, these ends are fastened in each case with a holder for the pulling device on the sliding supports or the angle profiles.
    Zugtechnisch it is advantageous to choose the attachment as close as possible in the direction of the Zugpunktes, thereby remains a guide when used stable and steerable. This means that an arrangement of the free ends of the towing element at the outer regions of the sliding supports (viewed in the direction of towing) is preferred.
    The sliding supports are provided for reinforcement with an angle profile which increases the rigidity of a flat material formed. In addition, this angle provides the ability to make it better an angle element or a hinge-like connection to a cross-sectional element. The individual components of the device can be made of plastic, for example. In particular, the sliding supports can be designed in such a way that they slide over the free-flowing materials lying on the floor. It is also conceivable that the on the bottom side facing side of the sliding pads is provided with a profile that improves the sliding properties.
    In order to achieve a better lubricity of the sliding supports, they can be made of plastic. Alternatively, the sliding surface of the sliding supports may be provided with plastic or an equal acting agent.
    A further embodiment provides that the cross-sectional element is designed to be height-adjustable, so that the distance from the lower edge of the transverse profile element to the bottom is variably adjustable.
    An alternative is to form the sliding elements of steel, if a high weight is needed. The transverse profile element is preferably made of a light metal, so that it can withstand the mechanical stress.
    A further alternative provides that the transverse profile element is provided with a Abziehklinge. This is preferably made of a different material and should protect the cross-sectional element from wear. The attachment can be made via riveted joints, gluing or detachable connections. In addition, it is advantageous to use a second transverse profile element in the sense of a stabilizing rod, wherein these transverse profile elements can be exchanged with each other and overhead. This distributes wear from one edge to multiple edges of two cross profile elements.
    A further embodiment provides that the sliding supports are replaced by other equally acting means, such as rollers.
    Another embodiment provides that the device is electrically driven or otherwise foreign or this can be similar to trailer coupling to a traction device. Furthermore, additional weights may be applied to the device as far as this improves the effect and the result.
    By repeatedly over-the-place-pulling this device in the longitudinal, transverse and diagonal directions, a relatively high flatness can be achieved in particular on the tennis court.
    It should be noted that the function of the inventive device is not limited to the use of tennis courts. In particular, it is suitable for allowing a leveling of areas occupied by granules or similar free-flowing consistencies. A use on ice is conceivable.
    Further advantageous embodiments will become apparent from the following description, the claims and the drawings.

    Description of the embodiments
    In Figs. 1 to 3, the basic idea of the device 1 is shown. It comprises two mutually parallel sliding supports 2, which are connected to each other with a transverse profile element 5 via fastening elements 7. The sliding supports 2 are formed in plan view as sliding shoes, preferably have rounded corners and have a certain thickness. Advantageously, they are at least slightly bent in towing direction (comparable to snowboards or skis). This is to prevent them from sliding over piles of free-flowing materials and not pushing them through.
    The cross-sectional element 5 is connected to the fastening element 7, which is mounted directly on the upper side of the sliding support 2 so that the ground, measured from the edge of the transverse profile element 5, which points to the ground, a distance A is formed by the Giant material can escape. This distance corresponds at least to the thickness of the sliding supports 2. Alternatively, it is also provided to reduce the distance or even greater, usually in dependence on which type of material is processed.
    The cross-sectional element 5 has a height which is suitable for distributing the free-flowing material. If the material exceeds this height, the material overcomes the height without being distributed. The height creates a kind of storage space, wherein the accumulated material is transported by the towing process. Preferably, by repeated pulling a uniform distribution is then achieved.
    The fastening elements 7 are angular elements, which produce a rectangular fixed or selectively releasable connection with the sliding support 2 and the cross-sectional element 5.
    To tow the device 1 on the ground, a drag element 9 is arranged at the ends on the side facing away from the bottom of the sliding supports 2 via fasteners 8. This drag element 9 is a hand umgreifbares rope which is attached at its free ends to the fastening elements 8.
    In Figs. 4 to 6, the inventive embodiment of the device 1 is shown, which carries the basic idea. It comprises two mutually parallel sliding supports 2, which are connected to a transverse profile element 5 via angle elements 10 with each other. The sliding supports 2 are formed in plan view as sliding shoes, preferably have rounded corners and have a certain thickness. The transverse profile element 5 is mounted directly on an angle section 3 of the sliding support 2, so that the distance to the bottom, measured from the edge of the transverse profile element 5, which faces the ground, a distance A is formed, through which the free-flowing material can escape.
    The angle section 3 extends in the longitudinal extension of the sliding supports 2 and is preferably arranged flush with the outer edge of the sliding support 2 on the inside, that is to say on the side facing the transverse profile element 5. This creates a storage space between the angle profiles and in the towing direction in front of the transverse profile element 5, in which the material moved by the transverse profile element 5 is "stored". During the towing process, the stored storage space is dragged along, and depending on requirements, the material is automatically removed from the storage space and spent by the distance A below the transverse profile element 5.
    The cross-sectional element 5 has a height which is suitable for distributing the free-flowing material. If the material exceeds this height, the material overcomes the height without being distributed. Only by repeated subtraction is then achieved a uniform distribution.
    To tow the device 1 on the ground, a drag element 9 is arranged at the ends on the side facing away from the bottom of the sliding supports 2 via fasteners 8. This drag element 9 is a hand umgreifbares rope which is attached at its free ends to the fastening elements 8.
    In contrast to the basic version of the invention, a stabilizing rod 4 is additionally arranged in the embodiment shown in FIGS. 4 to 6. This is arranged parallel to the transverse profile element 5 and also fixedly fixed via angle elements 10 to the angle profiles 3 of the sliding supports 2. This stabilizing rod 4 serves inter alia to increase the rigidity of the device 1.
    In order to achieve a further stabilization, an angle profile 3 is arranged parallel to the longitudinal extent of the sliding supports 2. This angle profile 3 stabilizes the sliding surface of the sliding support 2, such that at least a large part of the sliding support remains in contact with the free-flowing material. Bending and deformation is prevented. In addition, the angle section 3 offers the possibility of attachment means, for example, for the cross-sectional element to install.
    In addition, it is provided that the cross-sectional element 5 is provided with a Abziehklinge 6, which is preferably bolted to the cross-sectional element 5 or riveted or glued. It serves to reduce the wear of the transverse profile element 5. In addition, there is the possibility to replace the wear part of the peeling blade 6.
    In FIGS. 7 to 9, the second embodiment of the inventive device 1 is shown. It comprises two mutually parallel sliding supports 2, which are connected to each other with two transverse profile elements 5 via angle elements with axis of rotation 10. The sliding supports 2 are formed in plan view as sliding shoes, preferably have rounded corners and have a certain thickness. The transverse profile elements 5 are mounted directly on the angle profile 3 of the sliding support 2, so that the ground, measured from the edges of the transverse profile elements 5, which point to the ground, a distance A is formed, through which the free-flowing material can escape. The cross-sectional elements 5 have a height which is suitable for distributing the free-flowing material. If the material exceeds this height, the material overcomes the height without being distributed. Only by repeated subtraction is then achieved a uniform distribution.
    To tow the device 1 on the ground, a drag element 9 is arranged at the ends on the side facing away from the bottom of the sliding supports 2 via fasteners 8. This drag element 9 is a hand umgreifbares rope which is attached at its free ends to the fastening elements 8.
    In contrast to the basic version of the invention, a further transverse profile element 5 is additionally arranged in the embodiment shown in FIGS. 7 to 9. This is arranged parallel to the first transverse profile element 5 and also fixedly fixed via angle elements with a rotation axis 10 to the angle section 3 of the sliding support 2. This second transverse profile element 5 is used in particular to increase the rigidity of the device 1.
    In order to achieve a further stabilization, an angle profile 3 is arranged parallel to the longitudinal extension of the sliding supports 2 in each case. This angle profile 3 stabilizes the sliding surface of the sliding support 2, such that at least a large part of the sliding support remains in contact with the free-flowing material.
    In addition, it is provided that the cross-sectional element 5 is provided with a Abziehklinge 6, which is preferably bolted to the cross-sectional element 5 or riveted or glued. It serves to reduce the wear of the transverse profile element 5. In addition, there is the possibility to replace the wear part of the peeling blade 6.
    The angle elements 10 are configured in the second embodiment such that they not only keep the cross-sectional elements 5 at right angles to the sliding support 2, but allow for a certain angular range. For this hinges or other functional means are provided which allow a change in angle. For this purpose, the angle elements 10 on an axis of rotation, which is designed as a bolt / spring connector (either one of or combined). To ensure easy transport, it is intended to remove the bolts / spring plugs of the hinges. So that they are captive, these spring plugs are secured under bias. In order to react against occurring abrasion, the two transverse profile elements 5 can be interchanged and also crashed. The angle limitation is achieved by appropriate design of the transverse profile elements 5 by the free ends are formed accordingly (see Fig. 8). These form together with the angle section 3 the necessary stop.
