Definitions

  • the present invention relates to a lift safety device for slat blinds, with one, at least with one of the slats for lifting and lowering movements, motion-coupled, linearly moving along stationary frame parts of the store, and at least one pawl lever pivotable in the store lifting plane on the carriage, the locking of which by With carriage stroke, there is a linear pivot point shift on the carriage and terminal frictional contact with frame parts, as well as a drive transmission for lowering and raising a slat blind and a rotation protection device for slats of slat blinds and a roman blind with at least one of the devices mentioned.
  • the object of the present invention is to design a lift safety device of the type mentioned at the outset in such a way that, largely largely independently of the tolerance dimensions of the stop frame parts, it enables the carriage to be blocked extremely reliably against unauthorized lifting.
  • lever is mounted on the carriage in such a way that the distance from the terminal end portion to the pivot point of the lever on the carriage decreases when the lever pivoting angle is approached by 90 ° with respect to the direction of stroke of the blind.
  • the lever is preferably mounted on the carriage by means of a pin-groove connection, the groove being defined by a curve which is given by vectors with respect to the connecting part, the amount of which decreases with increasing position angle in the opposite stroke direction.
  • a lift safety device of the type mentioned the lever being able to be coupled between storage on the carriage and a docking section with a stroke drive for the store, in that a stop is provided on the carriage, to which the lever engages at least almost when a pivot position is assumed 90 ° with respect to the stroke direction in this direction, with the coupling of the lever and drive between this stop and the locking part, such that the lever pivots at least for the time being when pivoting up from the locking by means of the drive about this stop.
  • the latter is rotated by the abovementioned stop, which defines a shortened turning radius with respect to the pivoting radius between the locking part and the lever bearing on the carriage, thus increasing the lifting component of the locking part.
  • This rotary stop also ensures that the lever returns to a position when the carriage is pressed down in the locked position larger swivel radius is moved so that the 90 ° lever position is stabilized.
  • the locking part of the lever is designed as an edge.
  • the present invention further relates to a drive transmission for lowering and raising a slat blind, by means of a first belt-like element and for tilting the slats by means of a second belt-like element, the first element running on a drive element, the second on a driver arrangement which is rotatably mounted for this purpose is stored.
  • a drive edge driven on an axis for an elevator belt for lowering or. Pulling up the store is connected via a spiral spring, which is arranged on the circumference of the axis, to a driver arrangement, which comprises a sleeve, which is located above the spiral spring and is coaxial to the axis.
  • the spiral spring acts as a friction clutch between the drive wheel and the driver arrangement as long as the spring ends projecting through the driver arrangement bush do not act on stops.
  • the intended stops are introduced into the path of the spring ends acting as counter-stops in such a way that the torsion spring when it is opened or closed.
  • Lowering the store strikes, however ' in the case of blind positions in which a change in the inclination of the slats is to be controlled, whereby the driver arrangement rotates with the drive wheel.
  • This arrangement has the disadvantage, in addition to a relatively complicated structure, that with normal raising and lowering of the store, the friction between the drive axle of the wheel and the named spring, which occurs when the torsion spring is non-rotatably attached, has to be permanently overcome.
  • the present invention now aims to remedy the disadvantage mentioned in such a drive transmission and to design it so that the drive element for a first belt-like element, such as an elevator or. Lowering line, with a driver arrangement for a second belt-like element, such as another line for tilting the slats, is connected.
  • a first belt-like element such as an elevator or.
  • Lowering line with a driver arrangement for a second belt-like element, such as another line for tilting the slats, is connected.
  • the spring arrangement thus remains completely inactive when the transmitter is not coupled to the first element, ie when the store is raised and lowered normally. Only when the aforementioned first element is coupled to the transmitter via the driver, the latter acts on the spring arrangement, is the driver arrangement also moved via the spring arrangement without, however, tensioning of the spring being used, because there is also no relative rotation between the transmitter and driver arrangement , both of which run with the drive member. Only when in one or the other direction of rotation arre one of the rotational travel of the driver arrangement ting stop organs is reached, the driver assembly is rotationally fixed, with any further moving transmitter. Now the spring arrangement is tensioned and in this phase acts as a leakage protection in that usually a drive provided, such as an electric motor, does not come to a standstill for the drive element in an exactly predetermined angular position.
  • the coupling element preferably comprises at least one engagement element mounted on the transmitter, which protrudes into the movement path of at least one driver on the first element.
  • the coupling element be displaceable on the transmitter, preferably spring-loaded, and engage in a predetermined position with the housing and be displaceable from this position by the driver.
  • the coupling element comprises a slide, preferably spring-loaded slide, which is guided radially on the transmitter, and an indentation or indentation which engages in a predetermined rotational position with corresponding shaping or shaping, the tangent at least in the rotational position of the driver acts approximately parallel to the slide guide on the transmitter on the slide.
  • the transmitter include a cylinder sleeve located above a drive shaft for the organ, as well as the driver arrangement, with a torsion spring inserted between them as a spring element.
  • the torsion spring arranged in this way results in a torsion coupling between the transmitter and driver arrangement, which is only tensioned when the relative rotation of these two parts is forced.
  • a torsion spring has the further advantage that tensioning can take place in both relative directions of rotation of the transmitter and driver arrangement, with the result that an anti-rotation device in the aforementioned sense is realized in both drive directions of a drive unit provided, such as an electric motor.
  • a further aspect of the present invention proposes a rotation protection device for slats of slat blinds, in which the slats on the slat holders on the side can be lowered and raised, also tilted, and for the latter, the holder is connected to a tilting arrangement in which the tilting arrangement for the slat can be pivoted about the tilting axis relative to the slat holder, a release device responding to a predetermined tilting moment being provided between the tilting arrangement and the holder.
  • the possibility is basically created that the tilt drive connection to the slat is released, which prevents the slat from pivoting when the slat is in line, when the predetermined tilting moment is reached on the tilting arrangement on the slat and then released Relative pivotability mentioned is realized, which then the tilting arrangement on the upcoming slat, like the other slats, the pivoting movement, respectively. Can perform tilting movement without this affecting the prevented slat.
  • the release device is preferably designed as a latching arrangement between the holder and the tilting arrangement, e.g. in the form of a latching connection.
  • the tilting arrangement be resiliently tensioned against a relative pivoting with respect to the slat holder, which makes it easier to re-engage and when the pivoting obstacle on the slat is removed, the latter is at least almost driven into the intended tilting position when the pivoting obstacle is removed.
  • the lamella holder and the tilting arrangement are preferably axially braced against one another by a Federogan, whereby firstly when the rotary connection between the tilting arrangement and the lamella holder is released, the flap is largely prevented from fluttering, such as under the influence of wind, and secondly such fluttering is prevented when the tilting arrangement not by the tilt drive, like scissor links, is rotationally stabilized, which is the case when the lamella is raised by a lifting drive and the tilt drive is thus loose.
  • the stroke safety device, the drive transmission and the anti-rotation protection device are preferably used together a Roman blind is provided or in a desired combination, whereby, as already mentioned, the provision of the anti-rotation lock is forced together with the drive transmission.
  • a carriage 5 is mounted in a linearly displaceable manner in a store housing 1, for example guided with four pairs of rollers 3.
  • chain guides 9 are provided on the carriage 5 in the form of upstanding plates, between which a chain 11 is displaceable. Since the chain 11 lies in front of the figure level in the representations of FIGS. 1 and 2, it is only shown in broken lines.
  • the chain 11 carries at its end a driver cam 13, which cooperates with a locking lever 15, which has a locking edge 17 at the end, and is mounted on a trunnion 19 on the carriage 5.
  • the lever 15 extends from one side of the carriage through corresponding cutouts in the chain guides 9 to the area of the one carriage guide 7a, hereinafter referred to as the locking counter bearing.
  • the lever 15 rides in a guide groove 21 on the bearing pin 19.
  • the groove is bent in a kidney shape and has a width corresponding to the bearing pin diameter over its entire length, the groove center line m being fixed with reference to the locking edge 17 on the lever 15 by location vectors r, the amount of which decreases as the angle IP increases in the opposite stroke direction GH.
  • the pivotability of the lever 15 is limited in the counterclockwise direction by a limit stop 25 on the carriage 5.
  • a rotary stop 27 is provided on the carriage 5, the function of which will still be discussed.
  • the illustrated lifter works as follows:
  • the lever 15 assumes the position shown in FIG. 1, it tilts counterclockwise until its locking edge 17 rests on the locking counter bearing 7a. If the blocking object is removed from the path of movement of the lowest slat, the carriage falls until it rests on the driving cam 13.
  • the lever 15 passes through the positions a, b, c shown in dashed lines in FIG. 1. In a first swiveling range, it rotates around the bearing journal 19, the locking edge 17 tending to form an arc around this journal with the radius r a crosses out. As the trunnion 19 is pushed upwards in a linear movement when the trolley 5 is lifted and the radius r is greater than the a distance between the trunnion 19 and the locking counterbearing 7a, the lever 15 wedges along the guide groove 21 and thus forces the lever 15 to pivot in the direction indicated by A. The locking edge 17 forms the fulcrum.
  • Fig. 2 it is shown how the lever 15 is released when the locking is released by lifting the chain 11 with the driver cam 13.
  • the driver cam 13 viewed in the horizontal direction, acts on the lever 15 between the stop point of the limit stop 25 and the rotary stop 27 on the lever 15. Since, as shown, the guide groove 21 in the 90 ° locking position of the lever 15 in the region 19 receiving the pin is practically vertically oriented, the rotary stop 27 now acts as a fulcrum for the lever 15.
  • the lever 15 pivots in a first swing-back phase about the rotary stop 27, the locking edge 17 pivoting, at least almost, on a circular path with the radius of curvature r c around the rotary stop 27.
  • This radius of curvature r c is significantly smaller than the pivot radii r, r b , which determine the path of the locking edge 17 when it takes up its locking position. Due to this reduced path radius, the locking edge 17 is pivoted away from the locking contact with the locking counter bearing 7 even with a slight stroke of the driving cam 13. Thereafter, the lever 15 slides in the direction shown by B by now pivoting the guide groove 21 along the bearing pin 19 until the bearing pin 19 is again in contact with the upper guide groove part and the upper edge 16 while pulling the driving cam 13 on the rotary stop 27.

This is done by the mechanical stop mentioned. Since a drive element provided, for example an electric motor, which acts on the sprocket 35 via the hollow shaft 33, cannot usually be brought to a standstill exactly in a predetermined position, but instead extends beyond this TARGET position, the torsion spring 87 acts on this drive as Brake and for the entire drive device as overflow protection.
