Definitions

  • the invention relates to a drive unit for a slat curtain or the like. According to the preamble of claim 1.
  • Slat curtains consisting of a plurality of strip-shaped, rigid slats hanging next to one another, which can be pulled in a rail and pivoted about a vertical axis, are being used to an increasing extent, in particular in the commercial sector, i.e. for offices, etc.
  • the slats of such a slat curtain are moved by a pull chain running in the upper mounting rail, in both modern and particularly comfortable slat curtains by means of a single pull chain, both pulled and pivoted.
  • a pull chain is often a pull rope with knotted or otherwise attached driver beads.
  • traction chain instead of a traction chain, other traction elements, for example a plastic-coated wire rope or the like, are also known. Similar conditions as with lamella curtains also occur with normal curtains and other decorations to be drawn, so that the teaching also refers to this.
  • the pulling element in particular the pull chain, hangs down far enough from the running rail at one end of the slat curtain, so that an operator can pull the pull chain manually.
  • the pull chain runs revolving, i. H. endless.
  • an electric motor-driven drive unit is provided, which is attached directly to the running rail. Such a drive unit is the starting point for the teaching of the invention.
  • the known electromotive drive unit from which the invention is based sits directly on the running rail, namely at one end of the running rail of the lamella curtain.
  • An associated switching control device usually a simple open / close / stop switch, is separate from the Housing of the drive unit or somewhere in a suitable place on the nearest wall. Arranged.
  • the switching control device is regularly connected to the electric drive motor in the housing of the drive unit via a cable, which is usually flush-mounted.
  • the problem with the known, previously explained drive unit for a slat curtain is that it cannot be retrofitted particularly easily with existing slat curtains that can be operated by hand.
  • the traction element in particular the traction chain, must first be shortened and then closed again so that it is stretched around the drive pinion in the housing of the drive unit to be attached to the running rail.
  • a socket for the switching control device must be placed on the nearest wall and connected to the housing of the drive unit via connecting cables. Even if one thinks of a wireless connection of the switching control device and the electric drive motor of the drive unit with greater technical effort, the retrofitting is nevertheless not particularly easy and in any case costly.
  • the invention is based on the object, the known drive unit for a slat Curtain or the like. To design and develop such that it can be retrofitted inexpensively, simply and flexibly and in an emergency allows easy manual operation of the slat curtain.
  • the drive unit according to the invention solves the problem outlined above with the features of the characterizing part of claim 1.
  • the housing can be easily attached to a building wall and nevertheless the tension element, in particular the tension chain, can be inserted into the housing from above.
  • the tension element in particular the tension chain
  • the housing can be attached to a building wall away from the running track, but also to be arranged on the frame of an associated window or on the floor in front of the window.
  • the length of the pull element of the slat curtain which is matched to the manual operation of the slat curtain, can remain unchanged, since the housing of the drive unit according to the invention can be arranged precisely at the freely hanging end of the pull element due to the construction provided.
  • the switching control device can be easily arranged in or on the housing, so that a compact unit, i.e. an actual drive unit, for a slat curtain or. Like.
  • the drive unit according to the invention can be retrofitted to an existing, manually operated slat curtain or the like in a few simple steps, is compact, simple and inexpensive and, moreover, extremely easy to operate the slat curtain, since the length and arrangement of the pulling element, are tuned to the manual control, nothing needs to be changed.
  • Fig. 1 shows first in part a) how a conventional slat curtain is constructed, namely with a z. B. on the ceiling of a room arranged track 1 and vertically depending, strip-shaped, rigid slats 2. which is designed as a closed, circumferential chain and serves as a tension element for the slats 2 of the slat curtain.
  • a pull chain 4 plastic-coated wire ropes, plastic ropes, etc., that is to say all the tension elements which are customary and suitable for this type of application, can also be used as tension elements.
  • the slats 2 can be moved as a whole by means of the pull chain 4, that is to say they can be pulled in the running rail 1 and pivoted about their vertical axes.
  • the drive unit now has a housing 5, which preferably consists of plastic, in particular a thermoplastic, and accommodates an electric drive motor 6.
  • the electric drive motor 6 has assigned an electrical connection line and / or an accumulator, but this is not shown in detail in the drawing.
  • the drive motor 6 can be suitable, in particular size-matched electric drive motors, in particular it will be a direct current motor with a relatively low power and a relatively high speed, in particular a power of 10 to 15 watts and a speed of several thousand revolutions. It has been shown that these motors are particularly suitable for the present applications, since they are particularly small and, in conjunction with a step-down gear unit, nevertheless result in the required running speed of the pull chain 4.
  • such a drive unit usually has a reduction gear 79 connected downstream of the drive motor 6, as is indicated, for example, in FIG. 3.
  • a drive pinion 8 for the pull chain 4 coupled or a different drive element for other pull elements, for example a friction roller with a counter pressure roller or a spline for correspondingly other pull elements.
  • the housing 5 has a front wall 9, a rear wall 10 and front wall 9 and rear wall 10 connecting side walls 11 and end walls 12. Through an opening 13, the pulling element, which is designed as a pull chain 4 in the exemplary embodiment shown here, is inserted into the housing 5 and suspended on the drive pinion 8. In addition, a switching control device 14 is provided for the electric drive motor 6.
  • the drive unit as a whole namely the housing 5 of the drive unit, is arranged on the frame of the window which can be closed by the slats 2, and at a height which is the closed end of the pull chain 4 in the case of slat curtains which are usually operated by hand corresponds.
  • the opening 13 the housing 5 is arranged in a side wall 11 and, preferably, in the opposite side wall 11 there is a further corresponding opening 15 and in that the switching control device 14 or a receiving part of the switching control device 14 in or is arranged on the housing 5.
  • the main effect of this teaching has been explained in the general part of the description.
  • the second opening 15 in the lower side wall 11 opposite the upper side wall 11 can be clearly seen in FIGS. 6 and 8, which will be explained later. It also serves to ensure that the area of application of the drive unit is particularly wide, so that it can be used particularly flexibly.
  • this second opening 15 in the opposite side wall 11 it is in fact possible, by simply rotating the housing 5 in its plane by 180 °, to strike the housing 5 with its rear wall 10 instead of on the right now.
  • Fig. 1 b) makes it clear that the stop can be made on the right; visible that and how by turning the housing 5 and introducing the pull chain 4 on the other side wall 11 a stop is also possible on the left.
  • the front wall 9 be removable from the side walls 11 and end walls 12. This can be seen particularly well in FIG. 2. Inserting the pull chain 4 is particularly easy when the front wall 9 can be removed if the openings 13, 15 in the side walls 11 of the housing 5 are designed as approximately U-shaped slots which are open towards the front wall 9. The figures clearly show this slot shape of the openings 13, 15 which is open on one side.
  • Fig. 2 also shows that in the embodiment shown here, each opening 13, 15 is divided into two, namely has an inlet part and an outlet part. This makes it particularly easy to do tion of the pull chain 4 in the housing 5, around the drive pinion 8 around and out of the housing 5 possible.
  • Figures 1 b) and 2 to 8 relate to exemplary embodiments of the invention for a particularly frequent application, characterized in that the housing 5 can be fastened with the rear wall 10 to a building wall or the like and has corresponding fastening elements or fastening recesses for this purpose.
  • the direct rear wall fastening of the housing 5 to a building wall or the like is particularly expedient in terms of fastening technology, stable and simple to carry out.
  • this bearing axis can have a threaded socket 17 for a fastening screw 18 for fastening the front wall 9 to the rest of the housing 5, which is attached centrally to the front wall 9 and serves to fasten the front wall 9.
  • This is a stable and simple construction which, under certain circumstances and in the exemplary embodiment shown here, is also supplemented by a circumferential locking shoulder on the front wall 9, which engages in the frame-like side walls 11 and end walls 12.
  • the further embodiment of a drive unit shown in a perspective view in FIG. 5 is particularly interesting insofar as here the drive pinion 8 is assigned a second, preferably identical drive pinion 8 'and the drive pinions 8, 8' are arranged a short distance above one another, the distance performing the pulling element 4 in engagement with the drive pinions 8, 8 'allows and the thickness of the drive pinion 8, 8' perpendicular to the pulling direction is greater than twice the diameter of the pulling element 4.
  • the or Drive pinion 8, 8 'arranged around guide elements 20 for exact guidance of the tension element 4 are. Corresponding guide elements 20 are also indicated in FIG. 3 of the drawing.
  • the housing 5 is flat-plate-like and the drive motor 6, the reduction gear 7, if any, further components 16 such as a transformer or the like are in a front wall 9 and rear wall 10 parallel plane.
  • the components 16 in the embodiment shown here are two transformers and a circuit block.
  • Fig. 3 shows a preferred embodiment to the extent that here the drive pinion 8 is in the plane of the other parts.
  • the drive pinion 8 could also lie in a plane parallel thereto, but this would, under certain circumstances, unnecessarily increase the thickness of the housing 5.
  • FIG. 5 shows a particularly useful alternative to the previously described construction as namely the drive pinion 8, 8 ', the drive motor 6 and the reduction gear 7 are arranged in a separate carrier 21 which can be pivoted out of the housing 5 .
  • the pull element in the form of a pull chain 4 insert into the drive pinion 8, 8 '.
  • This is particularly favored in the present case in that the drive pinions 8, 8 'lie in a plane which is approximately perpendicular to the plane of the front wall 9 and rear wall 10.
  • the drive pinion 8, 8 ' are thus to a certain extent on the end wall of the carrier 21st
  • the carrier 21 could also be completely pulled out of the housing, in a way designed as a removable insert.
  • the arrangement of the drive pinion 8 in a plane perpendicular to the plane of the front wall 9 is otherwise possible regardless of whether a carrier 21 is provided or not.
  • the switching control device 14 is integrated in the front wall 9 or, preferably, in an end wall 12 in the exemplary embodiment shown here.
  • An integration of the switching control device 14 in the front wall is shown in Fig. 1 a). It is particularly useful for mounting on the visible side of a window frame, but has certain disadvantages for the dimensions of the housing 5. Consequently, it is particularly recommended that, as shown in FIGS. 1 b), 1 c) and 2 to 8, the switching control device 14 is integrated in the one end wall 12. This is a measure that is fundamentally independent of whether the housing 5 has an opening 13 or two openings 13, 15 in opposite side walls 11.
  • the housing 5, as preferably indicated by claim 1 can be converted by simply turning it 180 ° to the right or left stop, it is recommended that the wall carrying the switching control device 14, in particular the end wall 12, be removed from the housing 5 and, preferably, can be attached to the housing 5 in two positions offset by 180 °.
  • the wall carrying the switching control device 14 on the housing 5 By using the correct opening 13 or 15 on the one hand and a suitable arrangement of the end wall 12 with the switching control device 14 on the housing 5, the right-hand stop and the left-hand stop can be easily installed.
  • FIGS. 1 b) and 1 c) show a normal housing 5 in a cuboid shape, in which the side walls 11 and end walls 12 are exactly perpendicular to the front wall 9 and rear wall 10.
  • Fig. 1 b) suggests that there could be problems with the operation and reading of the switching control device 14 on the end wall 12 when attaching the housing 5 via the rear wall 10 to a housing wall.
  • an embodiment is designed in such a way that the front wall 12 carrying the switching control device 14 is not arranged perpendicularly, but rather inclined, with respect to the plane of the rear wall 10 or front wall 9, preferably with an inclination angle between 80 ° and 10 °, in particular from about 30 ° to 60 °.
  • the angle here is 45 °, but a somewhat steeper angle may be more expedient for an optimal reading.
  • the end wall carrying the switching control device can also be arranged at an acute or obtuse angle with respect to the side walls. This would lead to an improved readability from diagonally above.
  • FIG. 4 also shows that, for design reasons, it may be advisable to give the housing 5 an arcuate transition region 22 to the end wall carrying the switching control device 14.
  • the angular position of the end wall 12 is achieved in that the end wall 12 itself is flat, plate-shaped and that the side walls 11 at the ends facing the switching control device 14 end wall 12 in the form of miter cuts are beveled.
  • the alternative Embodiment which is shown schematically in Fig. 7, that the switching control device 14 end wall 12 is provided with side wall portions 19 and that the side wall portions 19 are chamfered at their free ends in the form of miter cuts. So here the side walls 11 are provided at the ends with edges perpendicular to the front wall 9 and rear wall 10.
  • FIG. 8 shows an alternative combined from the two previously explained possibilities, which is particularly distinguished by the fact that the free ends of the side wall sections 9 are chamfered with a miter angle corresponding to the miter angle of the side walls 11.
  • FIGS. 6 a) and 7 a) each show a housing 5 to be attached to the right, while FIGS. 6 b) and 7 b) each show a housing 5 to be attached to the left.
  • FIG. 7 makes it clear that here, on the one hand, the individual parts of the switching control device 14 can be accommodated in the somewhat wall-like end wall 12 with the switching control device 14, and on the other hand the end wall 12 is replaced by a smooth, flat end wall according to FIG. 6 can be, in which case a housing 5 similar to Fig. 1 b) or 1 c) is the result.
  • Fig. 8 makes it clear that the alternative shown here gives the optimal number of possible variations, namely without exchanging the side wall 12, only by realigning the right stop, left stop, angular position of the switching control device 14 and no angular position of the switching control device 14. Only the switching control device 14 in this case, at least with its operating elements and display elements, must also be able to be turned through 180 ° relative to the end wall 12 itself.
  • Fig. 9 makes it clear that the switching control device 14 is designed flat-plate-like or block-like.
  • the switching control device 14 forms So here practically the end wall 12 itself, namely its supporting body, which only has a thin plastic cover.
  • the switching control device 14 has an electronic circuit board with a timer and a control panel arranged on the circuit board and arranged parallel to the circuit board with control buttons and display of the timer. This results in a very flat, yet electronically extremely powerful arrangement that allows long-term programming of the drive unit, sun tracking and a large number of possible special programs. Equipped with a correspondingly powerful microprocessor and provided with corresponding control buttons, such a switching control device 14 can be made extremely compact.
  • the display of the timer can also be used for operator guidance and can be designed as a general alphanumeric display, as is known per se in pocket calculators, etc.
  • the switching control device 14 with end wall 12 according to FIG. 9 or in one of the geometric designs shown in FIGS. 5, 7 and 8 is designed as a closed component
  • the switching control device preferably by removing the corresponding end wall from Housing is removable and can be used as a remote control and is connected to the drive motor via an electrical control line or wirelessly to the receiving part remaining in the housing. Then you can either replace the missing end wall with the switching control device by a smooth end wall or leave the corresponding side open and provide that the housing has an additional inner wall behind the end wall carrying the switching control device, which shields the inside of the housing from the outside inaccessible .
  • a fully-fledged remote control of the drive unit according to the invention can be realized, it being possible at the same time without problems to have a sensible, adapted storage location for the switching control device designed as a remote control in the housing.
