    The present invention relates to a clamping device for clamping at least one belt, wherein the clamping device has a base body, on which at least two base web clamping bodies designed as webs for winding around the belt are arranged.
    Generic clamping devices are used, for example, to attach a load by means of a strapped belt or connect straps together in another way. A generic clamping device is e.g. known from DE 25 52 993. The forces required for clamping the belt in the tensioned state essentially result from the friction between the base body clamping bodies configured as a web and the belt wound around.
    In order to increase the friction and thus the holding forces on the belt, it is known that the body clamp body with a roughened, e.g. To provide serrated or wavy surface. The projections of these surfaces are intended to be pressed into the belt so as to increase the frictional forces. A disadvantage of these embodiments, however, is that in this way the wear on the belt is increased.
    The object of the invention is to propose an alternative way in which generic clamping devices can provide higher holding forces.
    According to the invention, this is achieved by arranging on the main body at least one third basic body clamping body designed as a lever pivotable relative to the main body, the third main body clamping body being arranged in a clamping device.
    Position for clamping the belt between the base body clamping bodies designed as a web and the third basic body clamping body is pivotable.
    It is therefore a basic idea of the present invention to combine the known per se designed as a web body clamp with an additional pivotable body clamp body, so that the third body clamp in the clamping position festkiemmt the belt together with the designed as a web body clamps. As a result, high holding forces on the tensioned belt are generated without the need for roughened surfaces or the like are necessary.
    The base body clamping bodies designed as webs for winding around the belt can each have a circular cross section. But it can also be realized other cross sections.
    To increase the frictional forces, it is generally advantageous to provide the largest possible friction surfaces available. In this sense, preferred embodiments of the invention provide that at least one of, preferably all, body clamp body has an at least partially, preferably completely, curved Gurtanlagefläche for conditioning the belt on the respective body clamp body. It is also expedient if the third basic body clamping body is designed as a kind of lever which can pivot on one side about an axis. In this sense, it can be provided that the third body clamp body is pivotable about a, preferably fixed in its position on the base body, axle pin. Particularly preferred embodiments provide that the axle pin and the two base body clamping bodies formed as webs for wrapping around the belt are arranged parallel to one another.
    In order to be able to press the belt as effectively as possible and with large friction surfaces against the main body clamping body designed as a web for winding the belt around the wheel, the following can be achieved: • Φ ΦΦΦΦ • Φ Φ Φ φ Φ ··· «« · ··········································································. ······························ preferred embodiments of the invention provide that at least one of the, preferably all, basic body clamping bodies comprises at least a portion of, preferably completely, curved Gurtanlagefläche for conditioning of the belt has on the respective body clamping body.
    When trained as a web body clamps may be so-called fixed webs. In this sense, it can be provided that at least one of, preferably all, designed as a web base body clamping body are fixed in his or her position on the base body. In order to simplify the threading of the belt on the basic body clamping body, but can also be provided that at least one of the base body clamping body designed as a web in its position relative to the base body adjustable, preferably pivotally mounted on the base body. Preferred embodiments of the invention provide that the designed as a web and adjustable in its position relative to the base body, preferably pivotally mounted on the base body clamping body in the clamping position between the other designed as a web body clamp and one or the axle to the third Main body clamping body is pivotable, is arranged. It is advantageous if this designed as a web, adjustable body clamp body is locked in at least one position. Preferably, this is the position in which it is arranged for clamping the belt. Alternatively or additionally, this adjustable body clamp can be used e.g. but also in its position in which it is arranged for threading the belt, be locked.
    The pivotable body clamp body may be seen in a cross section egg-shaped and / or crescent-shaped.
    Basically, it is pointed out that with clamping devices according to the invention not only straps but also ropes can be clamped. While straps are long flexible objects which have a much greater width than their thickness, ropes are usually provided with a circular cross-section.

    A method according to the invention for clamping at least one belt and / or at least one cable by means of a clamping device according to the invention provides that the belt or cable is wound around the base body clamping body formed as webs and pressed in the clamping position by means of the third body clamping body against the base body clamping body designed as webs , It is particularly favorable in the sense of high friction and thus also holding forces, when doing the belt between at least one of the base body clamping body designed as a web and the third basic body clamping body extends twice and abuts against itself. As a result, a particularly effective belt on belt friction or holding force is generated.
    Further features and details of preferred embodiments of the invention will become apparent from the following description of the figures.
    FIGS. 1 to 12 show an embodiment of a tensioning device with a clamping device according to the invention.
    In FIGS. 1 and 2, the clamping device according to the invention is shown in a perspective view and in a longitudinal section. In all representations referred to here as a longitudinal section are side views, in each case a side cheek of the main body 1 and the clamping lever 2 is taken or not shown, so that the underlying components become Visible. In these figures, the clamping lever 2 is removed from the clamping device or its base body 1. In the variant shown here two straps 3 can be clamped on the base body 1 or on the clamping device at the same time. The clamping each prevents removal of the straps 3 in the respective direction 23 of the clamping device or the base body 1. This is of course only an example. The invention may be clamping devices for only one belt 3 or also for more than two belts 3. The invention

    Clamping devices can, as realized in this embodiment, be formed as part of a clamping device with at least one clamping lever 2 for the clamping operation. If the belt only by hand, so tensioned without tensioning lever 2, so can waived the Schwenkachslager 27 for applying the clamping lever 2 who-5 the.
    As can be seen particularly well in the sectional view of FIG. 2, it is provided in this clamping device for clamping a belt 3, that on the base body 1 of the clamping device at least two formed as a web for wrapping around the Gur-10 tes 3 basic body clamping body 5 and 17 are arranged wherein on the base body 1 in addition at least a third, designed as a pivotable relative to the main body 1 lever body 4 is arranged, wherein the third body clamp 4 in a clamping position for clamping the belt 3 between the web formed as a body clamps 5 and 15 17 and the third body clamp 4 is pivotable. As a result, it is sufficient that in the clamping position shown in FIG. 2, the pivotable base body clamping body 4 presses the belt 3 against the two base body clamping bodies 5 and 17 designed as a web. By using two base body clamping bodies 5 and 17 designed as a web, it is possible, as in FIG. 2, for the belt 3 to be interposed between at least one base body clamping body 5 and 17, here the main body clamping body 5 and the third , Thus, the pivotable body clamp body 4 twice and thus adjacent to itself runs. By this belt-on-belt-resting 4 particularly high clamping forces are achieved in combination with the pressing of the belt 3 by means of the pivotable Grundkör-25 perklemmkörpers. The two formed as a web for wrapping around the belt 3 basic body clamping body 5 and 17 have in this embodiment a circular cross-section, but this need not necessarily be provided. By the particularly visible in Fig. 2 possibility of leading around the belt 2 to these two web-like basic body clamp body 5 and 17 and the additional pressing means of the third
    Main body clamping body 4 particularly high holding and clamping forces are achieved. I · ♦ > ········································································································································································
    Preferred embodiments, such as those shown here, moreover provide that the third, ie the pivotable main body clamping body 4, has recesses 18 and 19 for at least partially receiving the belt 3 and one of the base body clamping bodies 5 and 17, respectively. As a result, the clamping forces are increased again, as well as by the at least partially, preferably completely, curved Gurtanlageflächen 8 of the body clamp body 4, 5 and 17. In sum, this very high holding forces are achieved without it being necessary, the Gurtanlageflächen 8 roughened, ie with 10 ribs or waves or the like form. As a result, the belt 3 is protected in the long term and increases its life without this leading to losses in the achievable holding forces. The pivotable body clamp body 4 is pivotally mounted about a fixed axle pin 13 in this embodiment. Conveniently, the axle pin 13 and designed as a web base body-15 clamping body 4 and 5 parallel to each other.
    In Fig. 3 and Fig. 4, a clamping lever 2 for clamping, so to increase the clamping forces on the belt 3 is attached to this base body 1 and this clamping device according to FIGS. 1 and 2. For this purpose, in the embodiment shown here a simple-20 ches, designed in the form of a recess open on one side Schwenkachslager 27 running on the base body 1, in which the pivot axis 24 of the clamping lever 2 can be easily inserted. It is therefore a releasably fastened to the base body 1 clamping lever 2, the pivot axis 24 simply has to be inserted only in the Schwenkachslager 27. 25
    As can be seen particularly well in longitudinal section according to FIG. 4, the tensioning lever 2 of this exemplary embodiment has a deflection slat 14, which has an eccentrically arranged with respect to the pivot axis 24 Gurtanlagefläche 9 for the belt 3. Of course, this type of eccentricity can also be realized in other embodiments. An opening nose 6 of the pivotally arranged
    Base body clamping body 4 is in the clamping position shown in FIG. 4, the base body clamping body 4, 5 and 17 for deflecting the belt 3 to the opening nose 6 in a space 7 between a Gurtanlagefläche 8 of the body clamp body 5 and a Gurtanlagefläche 9 a clamping lever clamping device of the clamping lever 2. As a result, an opening, ie a pivoting away of the body clamp body 4 of the other two Grundkörperklemmkörpern 5 and 17 is achieved during clamping, so when pivoting the clamping lever 2 in the clamping direction 16, whereby the belt 3 can be stretched without between the body clamps 4, 5th and 17 and the cocking lever clamping device to be stretched unnecessarily. The clamping lever clamping device is constructed with the clamping lever clamping bodies 10,11 and 26 in this embodiment in its basic structure and interaction as the basic body clamping body 4, 5 and 17. In Fig. 3 and the associated longitudinal section of FIG. 4, the clamping lever 2 is in a starting position before a clamping stroke. In Fig. 6, which shows a longitudinal section through the situation shown in FIG. 5, a situation during the clamping stroke of the clamping lever 2 in the tensioning direction 16 is shown, in which the opening nose 6 of the pivotable body clamping body 4 is already pushed out of the gap 3 from the belt 3 and characterized the pivotable body clamp body 4 has been pivoted into a release position in which the belt 3 between the body clamps 4, 5 and 17 can be pulled through.
    In the following, the clamping operation is described by means of a comparison of FIGS. 4 and 6. The starting point is the state of FIG. 4. In this are the body clamp body 4, 5 and 17 in their clamping position in which they, as described above, clamp the belt 3. The opening nose 6, around which the belt 3 is guided or deflected, is located in an intermediate space 7 between the belt contact surface 8 of the base body clamping body 5 and a belt contact surface 9 of the tension lever clamping device, here the deflection gate 14. In the starting position shown in FIG. 4 at the beginning a clamping or pivoting operation in the clamping direction 16, the clamping lever clamping device is already closed, the belt 3 is thus already clamped between the clamping lever clamping bodies 10,11 and 26. Will now starting from Fig. 4 for the introduction of a clamping stroke or clamping operation of the clamping lever 2 in the clamping direction 16 about its pivot axis. 24 pivoted, the belt 3 is pulled in the direction shown in Fig. 10 12 direction. This has the consequence that the opening nose 6 is pushed out of the belt 3 guided around it out of the gap 7, whereby the basic body clamping body 4 is pivoted into a release position, in which the belt 3 of the 5 basic body clamping bodies 4, 5 and 17 released, ie is no longer clamped. This situation is exemplified in FIG. This ensures that the body clamp body 4, 5 and 17 open quickly during the clamping stroke and thus a large part of the pivoting path in the tensioning direction 16 is actually used for tightening or retightening the belt 3 in the direction 12 and not lost by stretching the belt 3 3 , As a result, a relatively large piece of the belt 3 is always transported per clamping stroke, which per clamping stroke a relatively large increase in the tension of the belt 3 can be achieved. This effect of the rapid opening by means of the opening nose 6, in this as well as other preferred embodiments, by the eccentricity of the Umlenkkulisse 14 and 15 whose Gurtanlagefläche 9 with respect to the pivot axis 24 is still reinforced. In this sense, it is favorable, as also realized here, that the belt 3 by the eccentricity of the Umlenkkulisse 14 and the Gurtanlagefläche 9 at the beginning of the clamping stroke of the clamping lever 2, when the body clamp body 4, 5 and 17 are in their clamping position, stronger is deflected to the opening nose 6, as if 20 of the belt 3 would run directly on the pivot axis 24. The selected eccentricity of the Gurtanlagefläche 9 of the Umlenkkulisse 14 has further the advantage that the base body clamping body 4, 5 and 17 at the end of the clamping stroke of the clamping lever 2 faster back to find their clamping position. This prevents that during the pivoting back of the clamping lever 2 in the opposite direction 25 clamping path ver-25 loren goes. In addition, the eccentricity of the Gurtanlagefläche 9 of the Umlenkkulisse 14 reduces the manual force required by the user during the Spannhubes. At the end of the clamping stroke, the clamping lever 2 can certainly not be pivoted any further in the clamping direction 16. He is then swung back in preparation for the next clamping stroke in the opposite direction 25 in the position shown in FIG. 30 The band 3 can be tightened in the direction 22 as necessary by hand between the open Spannhebelklemmkörpern 10, 11 and 26, while the body clamp body 4, 5 and 17 in its clamping position shown in FIG. 4 the • · · «· · * ·· ··· ··· »9 ·······························
    Hold strap 3 in the cocked position. The described clamping operation can be repeated as often as is necessary for the tensioning of the belt 3, so that a kind Endlospannvorrichtung is provided in which the maximum possible tensioning of the belt 3 is not limited by the clamping lever clamping device 5.
    The clamping lever clamping device is formed with its clamping lever clamping bodies 10,11 and 26, as already explained in essential features analogous to the basic body clamping bodies 4, 5 and 17. The operation of this clamping lever-10 clamping device corresponds to the interaction of the body clamp body 4, 5 and 17 as well as the respective structure. Again, the pivotally mounted on the clamping lever 2 Spannhebelklemmkörper 10 in the clamping position presses the belt 3 against the other two clamping lever clamp body 11 and 26. Again, the belt 3 is directly against itself, which in total particularly high clamping forces in 15 of the clamping position can be achieved , in this sense, therefore, the clamping lever 2 of this embodiment can be regarded as a clamping device for clamping a belt 3 according to the invention, wherein the clamping device has a base body in the form of the corresponding portions of the clamping lever 2, at least two as a web for wrapping around Belt 3 trained 20 body clamp, here in the form of clamping lever clamps 11 and 26 are arranged on the base body in the form of the clamping lever 2 at least a third, designed as a relative to the clamping lever 2 pivotable lever body clamp body is arranged in the form of Spannhebelklemmkörpers 10, said dri 25 is a Kiemmstellung for clamping the belt 3 between the clamping lever clamping bodies formed as a web 11 and 26 and the third clamping lever clamping body 10 is pivotable.
    In order to facilitate the threading of the belt between the three basic body clamping bodies 4, 5 and 30 and the clamping lever clamping bodies 10, 11 and 26, at least one of the base body clamping bodies or clamping lever clamping bodies 26 designed as a web can be in its position relative to the main body 1 or clamping lever 2 ver- * * # # # # # 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4. * ^ Q * ···· * adjustable on the body. In the embodiment shown here, this is exemplified on the clamping lever 2 or on the clamping lever clamping device realized by the trained as a web clamping lever clamping body 26 can be pivoted by means of the pivot lever 21 in the slot 15. Fig. 7 shows the position of the clamping lever clamping body 26, in which the belt 3 can be particularly easily threaded between the clamping lever clamping bodies 10,11 and 26.
    In Fig. 8, the adjustable clamping lever clamping body 26 is pivoted back into its operating position, in which it is arranged between the fixed web-like clamping lever clamping body 11 and the axle 13 of the pivotable clamping lever clamping body 10. Trained as a web, adjustable clamping lever clamp body 26 is locked in at least one position. In the illustrated embodiment, it can be locked in its two end positions. On the one hand, this is the position in which it is arranged for clamping the belt 3. In addition, this adjustable tension lever clamp body 26z.B. but also in its position in which it is arranged for threading the belt 3, are locked.
    In the illustrated embodiment, this is achieved by a biased by a spring detent pin. This is located on the handle portion 30 of the pivot lever 21 and engages in said end positions in the holes 31 and 32 in order to achieve the desired locking of the clamping lever clamping body 26 accordingly. To release this lock is pulled on the handle portion 30 so that the not visible locking pin here pulled out of the respective hole 31 and 32 and thus the lock is released.
    Fig. 9 shows the clamping position in which the pivotable clamping lever clamping body presses the belt 3 against the two web-like clamping lever clamping body 11 and 26. Although this is not explicitly shown here, it is nevertheless clear that the base body clamping body 17 may be pivotally mounted in a manner analogous to the clamping lever clamping body 26 in order to facilitate the threading of the belt 3.
    FIGS. 10, 11 and 12 show a release lever 29 for this embodiment. This is attached laterally on one of the pins 20 of the base body 1. Proves that it has a release bar 28, with which it can be inserted to open on the opening nose 6 of the pivotable body clamping body 4 acts. In the plan view of FIG. 12 is particularly good to see the one-sided attachment of the release lever 29 of this embodiment. 5
    Finally, it should be pointed out that even if the embodiment described here in detail refers to the use of a belt 3, clamping devices according to the invention are nevertheless certainly also suitable for the corresponding clamping or clamping of cables. 10 • ft ft ft ft ft ft ft ft •· • ft • ft ft ft ft * ft ···················································································· · Ft · ft · ft · ♦
