Definitions

  • the invention relates to a so-called curtain pull, that is to say a drive arrangement for an electrically operated curtain, according to the preamble of claim 1, as is known from US-A-4 683 935 is known.
  • Such electric curtain trains are used in particular in hotels used to a greater extent to make the guests more comfortable to use to offer, which has been shown to be often relative heavy curtains of motorized curtains in comparison for manual operation when opening and closing considerably be spared. However, you can also find them in public and semi-public buildings and especially with larger windows also used in private households.
  • a disadvantage of the known electric curtain pulls is that In the event of a power failure, the curtain does not move or only moves extremely difficult to open and close by hand over the Curtain (or an operating rod connected to the towing vehicle) exerted a tensile force on the towing carriage in the direction of the running rail is because this is firmly connected to a run of the drive belt and, accordingly, the resistors for moving the towing vehicle of the drive (including its gearbox) should be what due to the existing translation ratios is generally not possible. Since the train car at a drive that has come to a standstill due to a power failure is blocked, attempts are made to get one to open such a curtain by hand, therefore often to tear of the curtain or other damage.
  • one curtain that can be driven by means of an electric curtain pull can also be quite desirable to get one curtain that can be driven by means of an electric curtain pull to be able to close by hand in the event of a power failure, namely for example, when you have to rest during the day wants to issue.
  • the drive belt is designed as a so-called ball chain
  • the coupling bolt which is arranged and guided vertically in the towing vehicle, engages positively between two balls of the ball chain in the coupled state with its free end section facing away from the spring acting on it , and the slipping clutch created in this way must (and only) be uncoupled if a force (in the longitudinal direction of the ball chain) acts between the towing vehicle and the ball chain that is greater than a certain (lower) limit value. If no pulling force is exerted on the ball chain, or only a pulling force that is less than this limit value, the curtain pull is always in the coupled state.
  • the present invention has for its object a curtain to improve the genus described at the beginning that the curtain in question is in the event of a power failure can also be effortlessly opened and closed by hand, if the towing vehicle is uncoupled from the drive belt for so long by a force exerted on it in the direction of the running rail, which can be generated manually via the curtain (and thus can be moved freely in the running rail like the other running carriages) is until the drive belt is to be driven by the electric motor again, whereby it should also be possible to close the curtain again by motor press when the power failure is over without it any installation measures are required.
  • the ramp angle (s) to be selected depends, among other things. from the friction conditions between coupling pin and the one with it in Engaging side wall of the locking opening, since the at Applying manual force to the towing vehicle and thus to the coupling bolt generated frictional force between the coupling pin and Side wall of the locking opening must be overcome to the coupling bolt to allow sliding out of the locking opening. This would obviously not be possible if both the peripheral surface of the end section of the coupling bolt which engages in the latching opening as well as the side wall of the locking opening in parallel run to the longitudinal axis of the coupling pin, their angle to Longitudinal axis of the coupling pin is zero, and is not possible if the angle is only a few degrees.
  • this ramp angle must not be too large either, because then there is a risk that the coupling pin even then from the Detent opening slides when the drive from the electric motor over the Drive belt takes place because then in the direction of the running rail directional driving force to be transmitted from the clutch is greater can be than that required to disengage the clutch Force.
  • the ramp angle is not can be empirically determined individually for each application must, but that under normal conditions a ramp angle between 30 and 60 ° is suitable to ensure the desired result, namely that the coupling pin in normal engine operation remains in the latching opening while it is at a standstill Drive slides out of the locking opening when the towing vehicle passes over the Manual force applied to the curtain in the longitudinal direction of the running rail becomes.
  • the Second coupling part having a detent opening on the coupling bolt facing inside with at least one guide ramp is provided for guiding the coupling bolt, which is in Longitudinal direction of the running rail from the edge of the locking opening up to an end of the second coupling part, the height this guide ramp from the locking opening to the end of the second Coupling part decreases and there is so high that the free end portion of the coupling pin on the guide ramp runs up when the two coupling parts relative to each other be moved.
  • the second coupling part preferably with two guide ramps running counter to the latching opening Mistake.
  • the drive belt is preferably included in a manner known per se Provide through openings with the same mutual distance are provided so that trained in the manner of sprockets Deflection disks with their teeth in these through openings can grip, the second coupling part, which is preferred is designed as a tab on the drive belt facing it Is provided on the outside with form-fitting in the through openings of the drive belt grip around the second Connect the coupling part to the drive belt.
  • Such an arrangement can expediently be used at the same time around the mutually facing end sections of the drive belt to connect, to make the drive belt endless, if the second coupling part is substantially centered on the connection point the drive belt is arranged so that a separate Connection becomes unnecessary.
  • Fig. 1 shows the explanation of the present invention essential parts of a curtain train designated as a whole, with various parts omitted or shown broken away are to better illustrate the present invention to be able to.
  • the curtain pull 1 is an essential part a curtain, the curtain 2 also omitted in Fig. 1 is, but indicated in the figures la, 2 and 3 in the detail is.
  • Fig. La also shows fasteners 26, with which the curtain pull 1 e.g. on a lintel or to fix the ceiling of a room.
  • the curtain 2 has a plurality at its upper edge 2 ' attached by carriage 3, with locking hooks 4, each are to be snapped into an eyelet 5 (see FIG. 6).
  • the carriages 3 are provided with rollers 6, which are on a horizontal, stationary running rail 7 are supported (see FIG. 6). she are freely movable along the running rail 7.
  • the one arranged in the area of a vertical curtain edge 8 first carriage is designed as a train carriage 3 'and differentiates differs from the other carriages 3 essentially by that it is powered by the drive described below is, while the remaining carriage 3 with this directly but only connected via the curtain 2 are.
  • the drive consists of a dash-dotted in Fig. 1 Lines indicated electric motor 9 with a gear 10 connected is.
  • the gear 10 acts on one in FIG. 1 on the right End of the running rail 7 arranged in the gear housing, as Sprocket-designed drive disc with a vertical axis of rotation, whose teeth in recesses 11 of a self-contained, grab flexible drive belt 12, which at the other end of the Track 7 from a sprocket also formed Deflection pulley with a vertical axis of rotation is deflected.
  • the mode of operation in normal operating condition is such that the reversible electric motor 9 when actuated by a switch, not shown is driven in its one direction of rotation and the drive belt 12 drives via the transmission and the drive pulley, so that its two dreams 12 'and 12 "are in opposite directions Move direction in the running rail 7, the train carriage 3 'with the strand 12 'of the drive belt 12 is connected (see FIG.
  • the curtain 2 for example, from its open position in its closed position is moved by first with the Drive belt 12 in related towing cars 3 'is moved and takes the carriage 3 following it with him when the Curtain 2 is stretched between this and the towing vehicle 3 'and the like.
  • the curtain 2 is closed by actuating the electric motor 9 in the opposite direction of rotation, again the sole with the drive belt 12 connected towing vehicle 3 'driven until he drives against the carriage 3 next to him and take it with you and so on expressly pointed out that the neighboring 3 ' further carriages 3 are omitted in the drawing.
  • the first coupling part arranged on the towing vehicle 3 ' has 13 one in the direction of the run 12 'of the drive belt 12 laterally on the towing car 3 'projecting coupling pin 15, the one in the engaged, normal operating state with its free End portion 15 'in a locking opening 16 of the inside of the Drive belt 12 attached second coupling part 14 engages, namely, the coupling pin 15 becomes concentric by means of it surrounding compression spring 17 pressed into the locking opening 16.
  • the coupling pin 15 is against in the direction of its longitudinal axis 19 the restoring force of the spring 17 is movably mounted on the towing vehicle 3 '.
  • the coupling pin lies 15 in its uncoupled state with a stop 20 a side wall of the towing vehicle 3 ', the stop 20 the axial movement of the coupling pin while the Spring 17 limited so that the free end 15 'of the coupling pin 15 in the uncoupled state at a distance from the run 12 'of the drive belt 12 is arranged, so no connection between the train car 3 'and the drive belt 12 there.
  • the stop 20 is as Flange formed, on the opposite side of the stop Side the pre-tensioned as a coil spring Spring 17 is supported, which with its other end on the opposite side wall of the train carriage 3 'is supported.
  • That attached to the inside of the run 12 'of the drive belt 12 second coupling part 14 is a tab-shaped plastic molded part trained and has at its the coupling pin 15 facing inside two opposite to the locking opening 16 extending guide ramps 21 and 21 'for guiding the coupling bolt 15, which run in the longitudinal direction of the running rail 7 and each from the edge of the locking opening 16 to the end of extend second coupling part 14, the height of the guide ramps 21, 21 'of locking opening 16 to the respective end of the second coupling part 14 decreases and formed there so high is that the free end portion 15 'of the coupling pin 15th runs onto the relevant guide ramp 21 or 21 'if the two coupling halves 13 and 14 are relatively moved towards each other as explained below.
  • the second coupling part 14 is on the drive belt 12 facing the outside with lugs 22, which form-fitting in through openings 11 of the drive belt 12 to grab. Since the second coupling part 14 is centered on the two arranged end portions of the drive belt 12 facing each other is, this can be done by means of the second coupling part 14 can be made endless without taking further measures requirement.
  • the diameter D of the coupling pin is 3 mm. He attacks only slightly into the locking opening when engaged 16 a.
  • sectional view seen in the direction of the section line V-V 5 shows the profile of the running rail 7 and recognize that the strands 12 'and 12' 'of the drive belt 12 on the side walls the track 7 run.
  • FIG. 6 shows that the carriage 3rd between the two runs 12 ', 12' 'of the drive belt 12 in the Track 7 are guided, the carriage recognizable in Fig. 6 3 is omitted in FIG. 4, however.
  • Fig. 8 is a sectional view in Area of the first coupling part 13 or the coupling bolt 15.
