专利说明:
The present invention relates to a tensioning device for at least one sun or rain sail fastened on a winding shaft and extendable from the winding shaft with a cable pull system. In known sun or rain sails, cf. e.g. EP 0 865 557 B1 or DE 10 2006 047 899 B3, a tarpaulin is attached to a shaft that can be rotated by hand or by motor. The tarpaulin can be pulled out in one direction from this shaft. However, a relatively complex assembly of fasteners, e.g. on house walls or on supports, as well as an uneven tension in the sun or rain sail when rolling onto the shaft possible. Another sun or rain sail is known from DE 10 2006 047 899 B3. This known sun or rain sail consists of a curtain divided into two sections, which can be wound up on a common, centrally arranged winding shaft. The free ends of the sections are connected with a cable system in order to be able to pull the sections off the winding shaft. In a tarpaulin roof known from EP 0 865 557 B1, a tarpaulin is suspended with its ends on supports. The cables under tension can be rolled up by means of a cable winding roller provided with a drive, whereby the tarpaulin can be held taut by appropriate force introduction without the load-bearing structures being unduly stressed. It is the aim of the invention to provide a tensioning device which enables an optimal tensioning of a sun or rain sail in any position and at any time when rolling up and down. In particular, a cable system without external attachment points should be provided. The tensioning device according to the invention of the type mentioned above achieves this task above all by providing at least one sliding unit guided on at least one arm and movable by a cable and the sun or rain sail between the winding shaft and the arm essentially orthogonal / 16 to the axis the winding shaft can be rolled up and unrolled. The present clamping device has the advantage of simple assembly, since in principle only one attachment point, e.g. a foundation with a support in the form of a screen tube or the like is required. This simple assembly is achieved by the interaction of the winding shaft (known per se), as the actual carrier of the retractable and unrollable sun or rain sail, with the movable arm, the arm carrying the at least one sliding unit that rests on the arm between a rest position and an operating position is slidably mounted and is connected to the cable provided for tensioning the sun or rain sail. The tensioning device is self-contained and does not require any additional stationary attachment points. To achieve a smooth, balanced movement of the sliding unit with the aid of the cable, it is particularly advantageous if the sliding unit is formed from a sliding part, a pressure part and a compression spring arranged between the sliding part and the pressure part. The (respective) rope of the cable pull is attached to the (corresponding) sliding pressure part and irregular cable pull movements can be compensated for via the pressure spring (s). For an optimal pulling out of the sails, the gliding part is connected to a sail end. It is also favorable for the balanced movement of the cable and the rolling of the sail when the cable acts on the pressure part. For an efficient sail actuation, it is furthermore particularly advantageous if the sail fastening is arranged in an essentially triangular outline of the sun or rain sail, essentially as an extension of an imaginary center of gravity of the sun or rain sail starting from the winding shaft. In the sense of a space-saving design in the rest position and a span that is as wide as possible for the sail, it is also advantageous if the at least one arm can be moved from a first or rest position into an open second or operating position by at least one spring, preferably a tension spring , is preferably pivotable. The spring, in particular tension spring, supports the pivoting out of the (respective) arm. The spring itself can be a compression spring - depending on the arrangement of the construction - but is preferably a tension spring. Advantageously, the spring is simply a gas spring. To optimize the end position of the respective sail, it has also proven to be advantageous if the arm has a kink. In the retracted sailing position, the at least one arm can be just below the winding shaft with the sail. In addition, a rope pulley can deflect the rope to the end of the (respective) arm. Furthermore, the sail end can be positioned deep in the extended position of the sail. It is also advantageous if the pivot axis of the arm is arranged slightly obliquely, since then the arm is independent, i.e. can also extend without tension spring support. For the actuation of the tensioning device it is also favorable if the cable pull is formed by a spiral cable pull. It is also advantageous if a gear transmission is provided for driving the cable pull. As already mentioned above, it is advantageous in terms of a simple construction if the winding shaft is mounted on only one post. The invention also relates to a sun or rain sail with at least one sun or rain sail, i.e. a canvas or tarpaulin, and with a tensioning device according to the invention. The invention is explained in more detail below on the basis of an exemplary embodiment shown in the drawing, to which, however, it should not be limited. Show it: / 16 Figure 1 is a diagrammatic view of a two-part sun or rain sail, hereinafter briefly sun sail or simply sail, with a single post, in the spanned operating position. Figure 2 shows the upper part of this awning in the retracted rest position. 3 on a scale enlarged compared to FIGS. 1 and 2, a detailed sectional view of the construction in the region of the mounting of the winding shaft of the sun sail on the upright; 3A schematically shows a spiral-wound cable of the cable pull for the sail; 4 shows, in a representation comparable to that of FIG. 1, a spread-out sun sail, also with two sail parts and two arms, but now with two uprights for supporting the winding shaft; and Fig. 5 shows a comparable sail arrangement with two uprights, but here, unlike in Fig. 4, with two approximately trapezoidal sail parts. In Fig. 1, two sail parts 1 of a sun sail 1 'are shown, the parts of which are generally triangular and are fastened to a winding shaft 2, on which they can be wound up in the idle state (see FIG. 2), of which, however, as in Fig. 1 shown, can be handled with the help of ropes 3. 1, the cables 3 of the cable system lead to sliding parts 4 which are connected to the ends 5 of the sail parts 1. To manipulate the sail parts 1, tension springs 6 and a cable 7 are provided which start from the upper end of an individual upright 8, the base 9 of which enables the sun sail 1 'shown to be rotated. Arms 10 also extend from the upper end of the upright 8 and hold the outer ends 5 of the sail parts 1 via end fastenings 11. The cable pull mechanism is designed in such a way that when the arms 10 are extended, the respective canvas 1 is optimally tensioned so that the force acting pulls the sail / 16 end fastenings 11 exactly in the direction of a center of gravity, i.e. a line through a center of gravity 12 of the respective sail part 1 , The present construction is particularly suitable for freely cantilevered winding shafts 2, as shown in FIGS. 1 and 2, since then a “one-legged solution with only a simple post 8, in particular a tubular post 8, is possible, similar to that in FIG Case of a parasol construction. The sail parts 1 are rolled off the shaft 2 by means of the pivotable arms 10, which hold the sail parts 1 at their outer ends 5, cf. also the cable fastening parts 11 in FIG. 1. As mentioned, the line of action of the sail pull-out forces is preferred in the direction of the respective center of gravity 12 of the sail part 1, that is to say in the direction of a center of gravity, in order to achieve the best possible tension of the sail parts 1. In order to pull out the sail parts or sailclothes 1, in the exemplary embodiment shown, the isosceles triangular sailcloths 1, orthogonally to the winding shaft 2, the above-mentioned sliding parts 4 are provided, which, with a corresponding speed and therefore a corresponding position on the arms 10 from their arms shown in can extend approximately centrally arranged rest position into the end operating position on the arms 10, as shown in FIG. 1. The cable 7 is designed for this purpose as a spiral cable 7, with which it is possible to provide a lower pull-out speed at the beginning of the roll-out of the sail parts 1, on the other hand to accelerate the roll-out or unwinding process at the end of the pull-out process. In this way, the desired sliding movement of the sliding parts 4 on the arms can be achieved. The spiral cable 7 provided for this purpose is shown in more detail in FIGS. 3 and 3A. In the exemplary embodiment according to FIGS. 1 and 2, two cables 3 are provided, one for each arm 10, corresponding to the two arms 10, and the cable 7 provided for this purpose is illustrated in particular in FIG. 3, with the cables 3 being spiraled one above the other are guided between disks 13. The wrap is started with the smallest diameter, and / 16 for this purpose the rope is also fastened with a retraction through a slot 14 in the disks 13, the respective rope with an end button 15 at the innermost point of the disks 13, as close as possible the shaft 13 'is fixed. In order to lay the end head 15 as deep as possible, the shaft 13 'provided for the bearing is also conical, as shown at 16 in FIG. 3. The spiral cable 7, more precisely the two disks 13 with the shaft 13 ', is driven by a gear transmission 17 which is only shown schematically in FIG. 3. On the other hand, as shown in FIGS. 1 and 2, an electric motor 18 coupled to the winding shaft 2 is provided for driving the winding shaft 2, as is known per se, for example, in connection with extendable awnings. The deflection of the cable pull towards the disks 13 can be seen schematically in FIG. 3 at 19, and takes place directly in the area of a bracket 20 of the gear drive or gear 17. The gear of the gear drive or gear 17 is in detail via a hub 31 coupled to the shaft 2, and on the other hand, the hub 31 is connected to the upright 8 (FIGS. 1 and 2) via a joint 28 (see FIG. 3) so as to support the projecting shaft 2. When using the awning 1 ', the arms 10 are pulled outwards by the tension springs 6, i.e. away from each other and in particular pivoted away from the shaft 2. Gas springs are preferred as tension springs 6 for installation reasons, since they allow a comparatively small construction. 1 and 2, the pivot bearing 21 of the arms 10 on the upright 8 itself, in the present case in the manner of a leg, is advantageous for constructional or structural reasons. On the post 8, the arms 10 must therefore be placed a short distance above one another, i.e. can be pivoted. Lever arms 22 are provided for the gas tension springs 6, cf. Fig. 1 and Fig. 2, which are designed and arranged so that in the / 16th End position of the arms 10 (see FIG. 1) of which the highest tensile force is transmitted into the sail ends 5. In the retracted position (according to FIG. 2), however, the arms 10 transmit a comparatively small force to the sail ends 5. With an optimal spacing of the lever arms 22, the forces in the gas tension springs 6 can be balanced. The sliding parts 4 are preferably simply plugged onto the arms 10, and the cable rollers 26 at the ends of the arms 10 deflect the cables 3 to the sliding parts 4. With the described mechanics, the present arrangement is used for symmetrical sail parts 1; but it is quite conceivable to offset the sail parts 1 against each other, i.e. to be staggered along the shaft so that the sail ends 5 are not directly opposite one another with respect to the shaft 2, as is known per se. FIG. 4 shows an exemplary embodiment which essentially corresponds to the embodiment according to FIGS. 1 and 2, but with the arms 10 being short in comparison to FIG. 1 and opposite the upright 8 at the other end of the sail parts 1, a further upright 30 is provided for mounting the other end of the winding shaft 2. Of course, the canvas 1 can also be other than triangular, and there can also be, for example, only a one-sided arrangement of a triangular canvas 1 on the shaft 2. Just as in the case of triangular sailcloths 1, approximately trapezoidal or rectangular sailclothes 29 (see FIG. 5) can be provided on both sides of the winding shaft 2, or there can also be only a one-sided arrangement of a single (trapezoidal or rectangular) sailcloth 29. It should be mentioned here, however, that such trapezoidal sailcloths 29 (or more or less rectangular sailcloths) require two - or in the case of a double arrangement four - arm constructions with the support arms 10; see. in particular the embodiment according to FIG. 5 with the four arm constructions (four arms 10).
