The first form of the invention shown in figure 1-12. Proposed according to the invention tensioner for cord suitable in particular for use with stretch cords in the curtains, and cited as an example of a form of implementation shows the folded curtain to shade the window or doorway. The curtain is folded curtain 2, which is fixed on top of the moving bus 4 and the lower movable bus 6 and bus independently of each movably attached to the tension cords 8, 10. Stretch cords 8, 10 are part of vertically, part horizontally and pass through the folded curtain 2 in several vertical areas in which the folded curtain has the appropriate bandwidth holes, and mounted in the four corner regions of the opening subject to shading, respectively in one or designed for each cord, Myung is our least one proposed in accordance with the invention, the tensioning device 20 for a cord, which, for example, fixed to the window frame using glue or screws.

Figure 2-8 shown in detail the construction of the tensioning device 20 for cord. The base 22, which for alignment during installation using mounting screws provided with two longitudinal holes 24 has a slot 28, passing in the longitudinal direction 26. In the slot 28 with the possibility of longitudinal movement installed the diffraction element 30 and connected with it the locking element 32, and the locking element 32 through interacting with the fixing screw 34 can be fixed together with the diffraction element 30 in any longitudinal position in the slot 28.

Further, the base 22 has a clamping device 36 to the end of the cord, which in this embodiment is formed by a number of protrusions 38 along the longitudinal direction 26 and at a distance from the slots 28, and lying opposite the pins 40 so that the establishment of a number located in the longitudinal direction of the stretch of holes 41 for spherical thickening 42, which is mounted at the end of the subject to tension cord 44.

The diffraction element 30 at its remote from the locking element 32 end provided with extending 180° having a semicircular area 46 changing the direction, which the traveler is limited to protect from slipping off the device 31. The base 22 at its both ends is respectively extending at 90° element of rotation 48, 50.

In the state of application of the cord 44 coming from the outside at an angle of 90° to the longitudinal direction, first passes through the element of rotation 48, and he turns in a longitudinal direction 26 by 90° and then at 180° around the diffraction element 30 until you're in the region of the clamping device 36 end of the cord. There are at the end of the thickening 42 of the cord flush wound in the recess 41 for hanging, suitable for the length of the cord and its state of tension between the two pins 40 and the notches 38.

The cord tension may be regulated now by moving the diffraction element 30, and the diffraction element 30 in the desired position is fixed using the fixing screw 34.

Using the mirror in relation to the base 22 of the location of the diffraction element, the locking element and cord latter can change direction on the element turning 50, which lies opposite the element of rotation 48, and directed to the diffraction element 30, so that we obtain a simple adjustable tensioning device 20 for the cable to the left/right installation.

In the first form of implementation of the cord is held constantly in the plane defined by the rotation elements 46 and 48 or 50.

Preferred modulating the persistence of the diffraction element 30 and the locking element 32 is depicted in Fig.7 and 8. The diffraction element 30 has a clamping device 54 in the form of a hollow cylinder with a likewise cylindrical mounting clip 56, the diameter of which is slightly larger than the diameter of the clamping device 54. The locking element 32 provided with a cylindrical bore section 58 and a cylindrical locating pin 60. Landing area 58 is included with tightness in boarding clamp 56, so that the diffraction element 30 can firmly connected to the locking element 32 as shown in Fig.2-6.

Alternatively, this design allows this arrangement of the spring or elastic element, for example, a spring working in tension or compression, the diffraction element (in General: clamping device for the end of the cord)can elastically resist against the force pulling the cord. Specifically on Fig.9-12 depicts the push spring. Push the spring 62 (coil spring) is clamped on the installation pin 60 and one end rests in a landing area 58, and the outer diameter of the pressure spring 62 is less than or equal to the largest diameter section 58. Simultaneously, the inner diameter having the shape of a hollow cylinder clamping device 54 of the diffraction element 30 (parts 30, changing direction)is greater than or equal to the outside diameter of the pressure spring 62, so that it can be clamped in the clamping device 54, as shown is figure 9. Due to the fact that the push spring 62 is clamped on the installation pin 60 and supported on the side, the result is a relatively large area of the grip springs in the diffraction element 30 relative to the fastening of the clamping element 32 this eliminates the danger that push the spring 62 will be deflected sideways.

Due to the presence of a pressure spring 62 is obtained an altered effect on the tension in this form of implementation compared to the form of the figure 2-6, namely, with a certain springing. If it is desirable and spatial dimensions can allow one or more rotation elements (diffraction element 30, the rotation elements 48, 50) to be formed with small friction losses by means of rotating rollers.

On Fig-18 is illustrated a second form of embodiment of the invention. Pig in the perspective view shows a view of the folded curtains, like in figure 1, and in this example, passing vertically stretch cords respectively recorded in the tension device 80 for the cord, which is explained in more detail on Fig-18. Tension device 80 for the cord as a whole is made L-shaped and has a base 82, which is at right angles changes the direction of the shelf 84. The base 82 is supplied with passing in the longitudinal direction of the slot 86, in which the possibility of longitudinal displacement of the set e is ement rounding 88. The diffraction element 88 has an area of 90 change of direction is made in the form of a semicircle or half, which is limited by the device 92, protecting it from slipping off.

On both sides of the slot 86 is the number of passes in the longitudinal direction are located against each other fixing holes 94, in which, by means zapressovyvajutsja pin, clamping screw, etc. in the selected position can be attached to the clamping device 96 to the end of the cord. Clamping device 96 to the end of the cord provided with the cut out in the rear hole, which can easily be wound and from which can be easily removed thickening 42 subject to tension cord 44.

On the shelf 84, changing direction, fixed dowel pin 98 to install a pressure spring 100, and the diffraction element 88 has a clamping device in the form of a hollow cylinder dowel pin and pressure spring as it is presented on Fig.7 and 8 for diffraction element 30 and the locking element 32 and described above. Thus, there is the possibility of applying a tensioning device 80 for cord without a pressure spring 100, and in this case, the diffraction element 88 in its lower limit position is in contact with the shelf 84, changing direction, and the tension of the cord is determined only by the installation of the clamping device 96 to the end of the Nura in a hole 94 for the commit.

Shelf 84 changing direction, provided with two parallel, spaced from each other by the rotation elements 102, 104. Thanks to the translation of the clamping device 96 to the end of the cord into one or the other row of holes for fixing and laying of the cord through one or another element of rotation 102, 104 there is also the possibility of simple adaptation to left-hand or right-hand execution.

In this form of implementation progress of the cord so that the cord, ending in a locking device for the end of the cord passes around the diffraction element in the first plane parallel to the longitudinal direction and then through one of the rotation elements 102, 104 again turns 180° in a second plane, which is perpendicular to the first plane, and likewise parallel to the longitudinal direction. Leaving the cord passes in the longitudinal direction at a distance from the base 82 and also at a distance from both end sections of the cord, deployed on the diffraction element.

Fig-25 explain the third form of embodiment of the invention. Fig shows the folded curtain, vertical stretch cords which fastened under tension by means of four tension device 120 to the cord, as it is in detail shown on Fig-25.

Tension device 120 for plug has a base 122 which n is one end provided with a fixed element of rotation 124. The reference axis 126 extends parallel to the longitudinal direction 26 at a distance from the base 122 and is attached to the two fixing nozzles 128 on the base 122. Clamping device 130 to the end of the cord is fixed for rotation and longitudinal movement on the support axis 126 and held apart in the longitudinal direction of the pressure spring 132 supported on the locking cap 128 and the element of rotation 124.

While on Fig-24 shows the "right" performance, Fig shows the corresponding "left" execution. When comparing both versions, it becomes clear advantage of the rotating installation clamping device 130 to the end of the cord to the reference axis 126. Namely, the clamping device 130 to the end of the cord should not be different (mirror) design base 122 for "left" and "right" version, and one version, as shown in Fig-25, and a clamping device during execution according pig for easy installation of the cord end can be rotated 90° or 180° around the reference axis 126, and then back again in the position shown in Fig.

In the depicted embodiment, the clamping device 130 to the end of the cord has three different docking positions, which are formed by corresponding grooves 134 and the longitudinal slot 136. The thickened end of the cord, in the present example, this W is roomrate body 42 for attaching to the end of the cord 44, may wind up in one of the notches 134.

In this form of implementation of the cord in the field tensioner for cord lies in the same plane, and there is only one single element of the rotation. Element rotation ensures that the cord coming out of the tensioner for cord, passed in the longitudinal direction on the outside and at a distance from the base 122, and the distance from the end of the cord along with him pinned on the ground.

On Fig shows a variant form of the implementation presented in figure 2-6, and instead of multiple fixing holes and pins are provided for the receiving hole 140 for magnets 142. The magnet serves to interact with the ferromagnetic body located in the mobile bus curtains (approximately according to 1)to hold the bus in an open and closed position. Of course, the magnet may vary with the ferromagnetic element, i.e. a tensioning device according pig in the receiving hole 140 may be located ferromagnetic element of the appropriate size, and paired magnet can be installed in the mobile bus.

On Fig shows the variant depicted in Fig-18 forms of implementation. In this case, the magnet 142 is installed in the receiving hole 140, which is already open area shelves tensioner for cord, so do not require the is almost no change in design. In addition to Fig-18 Fig shows two end cap 144, 146 that are looming on the tensioner for cord and it gets visually pleasant appearance (top image).

On Fig and 29 schematically shows two tensioner for cord for blinds in accordance with figure 1, and there are four tension cord 8a,b and 10a,b. On Fig first tension cord 8A passes, leaving the left at the top of the tensioner for cord 20, vertically down to the top of the moving bus 4, then about 2/3 of the width of the curtains horizontally or parallel bus 4 (and as usual in the bus) and then perpendicular to it to the bottom of the moving bus 6, which again changes direction by 90° and passes the remaining width of the curtains to the opposite edges of the curtains in parallel or in a bus, where once again changes direction by 90° and is directed to a located on the right at the bottom of the tensioner 20 for cord. The second tension cord 8b is initially parallel to the first tensioning cord 8a, inside the top of the bus, however, up to 15 opposite the end where after changing the direction by 90° to the second bus, and after the new changes direction by 90° through him back to the opposite end, where again deflected by 90° down and comes up at the bottom of the left located tensioner 20 glasner.

The third and fourth tension cords 10a,b symmetrical to the first and second tensioning cord relative to the longitudinal middle plane 11 of the curtains.

Depicted on Fig stroke cord differs from that presented in Fig that the second tension cord 8b and the fourth stretch cord 10b in the lower bus 6 again fully expanded back, but end in the respectively closest lying tensioning device 20 for cord.

On Fig shows a variant, in General, six tension cords, which are like the location on Fig. The first tension cord 8A vertically deployed in the middle of the curtains between the first and second tires, while the second cord 8b approximately in the middle between the middle of the curtains and the right edge of the curtains deployed vertically between the tires. The third tension cord 8c deployed like the second tensioning cord 8b on Fig in the area of the right edge of the curtains or in the field right ends of the tire 4, 6. From the fourth to the sixth stretch cords 10a, b, c are located symmetrically relative to the longitudinal Central plane 11.

In all cases, it is expedient if, respectively, all ending in a tension device for a cord tensioning cords, i.e. approximately Fig pairs 8a, 8b (top left), 10a, 10b (top right) 10a, 8b (bottom left) and 8a, 10b (bottom right) are connected at their ends and as a single tow in is displayed in the appropriate tensioner for cord, so a single process of attachment and tension and not each cord should be stretched separately. In this case, harness, consisting of several simultaneously pulled the ends of the cords forming the end of the cord in the sense of the invention.
