(57) Abstract:

Usage: in devices for hanging plate louvers or similar items. The inventive device includes a profile that is open at least on one side, with a guide, in which the number of brackets, and each has the gear and the possibility of movement along the guide by means of a control device, a control rod mounted in rotatably and parallel to the profile, which takes place in each case via one of the gears of the gear mechanism, a vertical rotating the finger with a connecting element for a plate attached to the other toothed wheel and supported by the bracket, the spacer strip is attached to each of the brackets, which is controlled by a slide in the guide adjacent the bracket, in which the spacer strip is attached to the side of the bracket so that the plane of the crossbar vertically oriented in order to create a profile, brought to the required size, so it looks great from an aesthetic point of view, did not require a large space, especially in height, and could therefore be combined with the device for suspension of lamellar blinds or similar objects.

The known device, including

profile, open at least on one side, with the guide;

the number of brackets, and each has the gear and the possibility of movement along the guide by means of a control device,

a control rod mounted in rotatably and parallel to the profile, which takes place in each case via one of the gears of the gear mechanism,

vertical rotating the finger with a connecting element for a plate attached to the other toothed wheel and supported by the bracket,

spacer plate attached to each of the brackets, and which is controlled by the sliding of the guide adjacent the bracket [1]

Such a device is often used for closing openings such as Windows, to each end of the window plate have evenly over the entire surface of the hole, and the plate is carried out more or less overlapping position by rotation around the vertical axis.

The plates themselves are located on the surface of the hole by placing one bracket at a distance from each other, and this interval is determined stomatol with him, moreover, this movement again is determined by the next spacer. A disadvantage of the known devices is that the profile in which the bracket moves relatively high, which improves the appearance of the blinds in General. A set of spacer strips, nested in each other, in any case requires a large thickness, and the size of this set is added to the height of the bracket.

The purpose of the described invention is to provide a profile of the required size with a good design.

The device described has a difference in that the spacer strip is attached to the side of the bracket so that the plane of the crossbar vertically oriented.

Due to the vertical arrangement plane of the strap a set of spacer elements nested in each other, not gaining height and width, and it can be used for more delicate items, since the most favorable self-sustained effect is achieved by a vertical arrangement of the spacer element, it also reduces the thickness of the set. Moreover, the advantage of such records that the guide rail of the blinds can be installed at an angle to the horizon, where the brackets are nevertheless kept in the right position to u is supplemented flax pipe with continuous, pointed inside a partial wall on each side wall between the bottom and the top of the wall to create a cavity formed with the upper or lower wall on one side to receive a standing bars profile, and on the other side of the guide brackets.

In this latter case, the distance between the partial partition and the top or bottom wall is at least equal to the diameter of the moving wheel, located on the bracket.

The total height of the profile is actually associated with the height of the bracket so that the profile can almost contain a bracket with a tight fit.

In a preferred embodiment, the guide is made in the upper wall of the profile to receive the end of a lever arm attached to the bracket.

In Fig. 1 shows a top view in perspective of the blinds according to the invention, in which part of the guide profile removed for clarity, of Fig. 2 is a view in perspective of parts of the device, namely the bracket and the component working together with him on Fig. 1, in Fig. 3 a perspective view according to Fig. 2 other parts of the device of Fig. 1, in Fig. 4 a cross-section of the device of Fig. 1, is provided with an additional profile, in which each gear in the bracket to freewheel.

The device shown in Fig. 1, consists of a hollow profile 1, which is preferably tubular and has a longitudinal slot 2 in the bottom wall through which the connecting elements 3 of each plate 4 can move. Profile 1 is attached to the ceiling or other fixed part of the structure in a manner not shown in further, but so that a continuous slot 2 lying on the bottom of the profile.

The brackets 5 are accepted in the profile so that each bracket is provided on each side moving wheel 6. It's a moving wheel has the capability of free rotation around a fixed to the bracket axis 7. The bracket 5 with the axis 7 is preferably designed as a cast of a suitable material, for example plastic.

The bracket is a gear 8, consisting of a worm wheel 9 and the toothed roller 10. The worm wheel 9 has a Central hole through which passes the control rod 11 arranged parallel to the profile. The control rod 11 is not round, it is done so that when the shaft 11 is rotated, the worm wheel 9 can rotate together with it. The worm wheel 9 causes the rotating toothed roller 10. The spindle 12 swazoo is the fact that the item, done as a strap of suitable material and which according to the invention fastened tightly at one end in a recess 13 of the side bracket 5. The niche is further provided with a plate 14 that faces away from the bottom wall 13 niches, this is to ensure that not only one end of the strap could not pass in the space between the plate 14 and bottom 13 niches, but also to the other end of the standing strap adjacent the bracket was not able to do the same 17 in Fig. 1. The other end of the strap provided with a stopper 15, which prevents the extension of the other end in the recess 13 adjacent bracket.

Profile 1 is equipped on the inner side 16 of the rib 17, oriented parallel to the top and bottom walls, which together with the bottom wall 18 and side wall 19 form a cavity 20 located on the side of the moving part of the bracket 5. This cavity 20 is used to make straps that are pushed to the top of each previous, when the brackets are drawn to each other. The rib 17 also serves to support the moving wheels 7 of the bracket 5, as with the upper wall 21 of the profile 1 this edge 17 forms reloadable guide, see also Fig. 4.

On the upper wall 21 is also executed perform the bosom of the bracket 5 and out of the rectangle in the profile 1 and thus to allow sliding of the brackets 5 along the rod 11 and the sliding of the strap in the recess 13. If necessary, the lever 24 with the same functions can be performed also on the bottom surface of the bracket 5, see Fig. 3.

The bracket 5 can slide in the profile 1 in the direction of arrow 25 by means of a control element in the form of a pull cord 26. In the first lower-right corner of Fig. 1 shows the two parts of the pull cord 26, which are sent around the wheel reverse at the end (not shown) of the profile 1. Part of the pull cord 26 is attached to the last bracket in a row, which is also not shown. The last bracket moving in the opposite direction by means of the pull cord 26, the latter bracket pulls the next bracket along through the strap every time when the maximum distance between brackets. When the cord extends in the opposite direction, the last bracket will push the previous arms forward until they fall against each other.

The pull cord 26 can pass through the profile 1 in the front part of the element 27 by means of guide wheels 28, in which the cords are moving through the opening 29 of each bracket 5.

The head element is end of support rod 11, in which bearing receives the rod 11 for free rotation. The end of the rod, Viacom the drive wheel 31. The drive sprocket 31 has a peripheral ring 32 with grooves for receiving ball chain that, when one part of the chain is pulled, causes the wheel with the ring 32 to rotate in the direction of the arrow 33, on which a gear wheel 30 also starts to rotate according to arrow 34 through a gear wheel. A gear wheel 30 carries the rod 11 and with it the worm gear 9 in each bracket 5.

The head element 27 is made similar to the brackets using injection molding, there are various components for free rotation. Idler wheel 28 for the pull cord 26, for example, has on both ends of the fittings 40, 35, which are received in the recess 36 of the wall element 27. The direction of the cord is chrysopogon insert part 37 with the recess 36, which can be inserted into Celerity item 27 according to arrow 38. Round the rear wall 39 of the insert 37 has a through hole 40 for the passage of parts of the cord 26.

A hole 41 for receiving the shaft 42 of the wheel 32 with the ring embedded in the pavement item 43 cast parts 32. The other end of the shaft 42 is received rotatably in the head cover 43, which may be associated with cast part 27 of the screws which mount the system drive cord and setting the rotational system of the plates 4 is achieved only by means of the screws 44 on either side of the head cover 43.

Fig. 5 shows a variant of the bracket 5, which is vertically located the spacer strip on both sides of the bracket. The spacer strips can be received in a cavity similar to the cavity 20 on the other side of the profile 1, see Fig. 4, so that hardly any increase in the size of the profile 1 is necessary.

On the underside of the spindle 12, which is located in the toothed roller 10, is made as one part connecting element 3, which has the form of pincers. Two oppositely located part mites somewhat flexible relative to each other due to the use of plastics, so that the strap is attached to the plate and having a hanging holder 46 can be located through the gap between the parts 3 ticks in the direction of the arrow 47. The holder 46 has a thickness in the upper part 48, which prevents the pulling plate of the pincer connecting element 3 unexpectedly. If you want to replace the plate, it is only necessary to pull the holder of the pincer connecting element 3 in the direction of arrow 49.

Further description of the invention with reference to Fig. 6 and 7, two different variants of the friction clutch between the gear mechanism and the rod 11 with one Fig. 6 the Central hole of the worm gear 5 is made with a longitudinal wedges 50, which are fitted in the longitudinal grooves 51 of the rod 11. This makes it possible to slide the worm gear 9, therefore, the sliding bracket 5 relative to the rod 11, but when the shaft 11 rotates, the worm wheel 9 can rotate together with it. When the worm wheel 7, which has only one thread, rotating, toothed roller 10, which is received in the bracket 5 for free rotation, will rotate. With the passage of the spindle 12 through the Central hole of the toothed roller 10, the upper end of the spindle will lie at the upper end of the toothed roller 10 and will for sure come in support of such a hole of the bracket 5, in this case, the toothed roller 10 is independently supporting surface, made in the bracket 5. Toothed roller 10 is made on the upper side of the pointed forward flange 52, which elastically standing still against the inclined surface 53 of the spindle 12. This elastic mechanism ensures the coupling between the spindle 12 and the toothed roller 10, so that when the spindle 12 will be jammed as a result of obstacles in the blind 4, the rod 11 can still be rotated further, since the toothed roller ndel 12 is a similar way of the inclined surface 53, which works together with the flanges of the coupling gear 52 of the platen 10. The spindle 12 additionally has a protrusion 54, which falls into the gap between the flanges 52 of the toothed roller 10, and thus the not-rotary connection between the spindle 12 and the toothed roller 10.

The rod 11 has three grooves that work together with the wedges 50 of the clutch sleeve 55. This clutch sleeve is made with a protruding elastic ridge 56, which acts together with the axial teeth 57 on the inner wall of the center hole of the worm wheel 9. In this version, when the rotation shaft 11 of its rotation relative to the worm wheel 9 is also possible because the ridge 56 will enter the next recess between the teeth 57. A friction clutch, also here allows relative movement of rotation between the rod 11 and the spindle 12.

In both specific performances thickened upper portion of the spindle 12 lies opposite end edges of the flanges 52, in order to be able to lock the spindle 12 in the gear shaft 10 in the axial direction. This is the second function of the flanges 52. The spindle can be removed from the toothed roller without upasani that the brackets at the end of the rail.
