Definitions

  • the invention relates to a roller shutter with a lamella armor which can be moved in lateral guide rails over an extension length and can be wound up or unwound from a winding roller arranged in a roller shutter box, with the last lamella at the free end of the shell the free end of a spring or roll wound on a roller, which in turn is housed in a roller blind box or roller blinds, and the blind box is located below the last lamella of the tank.
  • Roller shutters are used to a large extent both as new build roller shutters, as top-mounted elements or as mini roller shutters and, although they allow full or partial locking of window or door openings, this is also always associated with a corresponding locking of the area over which the roller shutter is lowered.
  • conventional roller shutters are practically not suitable for darkening the interior of the room from outside light, for example, or even for not closing the surface of the window or doors, but only to prevent insects or the like from entering.
  • the known roller shutters are therefore suitable for closing the surface of a window or door against unauthorized entry from the outside, but they cannot perform the other functions shown at all or only inadequately.
  • a roller shutter of the type mentioned is already known, in which a roller shutter box with a smaller fabric or lattice roller blind is attached below the window opening.
  • the free end of the fabric or lattice roller blind wound in the roller shutter box under spring tension can be coupled to the last lamella of the tank by means of a coupling device, so that when the tank is pulled up, the fabric or lattice roller blind is pulled up together with the window opening from below and thereby from the tank released window opening z. B. can be covered as mosquito repellent.
  • a roller blind box below the window opening because there is often no suitable space available for this.
  • the window area released by the armor from the lattice or fabric roller blind can only be covered completely (when the roller blind is coupled) or not at all (when the roller blind is uncoupled): a partial covering of this window area released by the armor by the fabric or lattice roller blind , for example for the purpose of darkening sunlight only for a part of the window area released by the roller shutter, is not possible.
  • the invention now seeks to remedy the situation and design a roller shutter of the type mentioned in such a way that the possibilities of a lattice or fabric roller blind can also be used with it only for partial areas of the window or door surface released by the roller shutter curtain and easy retrofitting to already existing ones Roller shutters is possible.
  • roller shutter of the type mentioned in that the roller shutter can be moved over the extension length of the tank, can be locked at any height within the extension length by means of a locking device and in the non-locked position by the spring tension always in contact with the last slat of the tank is pressed, that is to put on them.
  • the invention thus organizes at the bottom of the armor of a conventional roller shutter, a roller blind, which is wound up in a small box and attached with its free end directly to the roller shutter curtain.
  • this roller blind in the rolled-up state (because it is under spring tension) always moves up and down with the armor when moving the roller shutter curtain up and down at the bottom, namely hanging from its last slat and pressed against it is, with its roller blind box, so to speak, a kind of "closing lamella" of the roller shutter. If you bring the roller shutter with its last slat to a certain height, you bring the roller blind box to a corresponding height.
  • the roller shutter according to the invention creates a surprisingly simple possibility for an effective combination of the functions of a roller shutter with those of a fabric or lattice roller blind, the total space required for installation not being greater than that for a conventional roller shutter.
  • Part of the window or door opening released by the roller shutter according to the invention can be kept completely open and only from a desired height, for. B. a suitable blackout or sun protection effect can be achieved.
  • this locking there is of course the possibility of providing special locking devices for this purpose in the overall construction of the roller shutter, for example appropriately arranged locking bolts for the roller shutter box distributed over the height.
  • a further preferred embodiment of the roller shutter according to the invention also consists in the fact that the roller blind box, like the slats of the armor, is guided in the lateral guide rails.
  • the roller blind box like the slats of the armor, is guided in the lateral guide rails.
  • the use of special guide devices for the roller blind box is avoided and the possibilities of the existing side guide strips are advantageously used.
  • a small box is provided for the roller blind box, the outer dimensions of which are of course also essentially determined by the length of the lattice or fabric roller blind to be wound up.
  • the roller shutter box is designed with a depth and a height that each correspond approximately to the height dimensions of a slat of the roller shutter curtain, which results in a particularly pleasing appearance of the entire roller shutter and the roller shutter box attached below also represents a final "end slat" optically.
  • height dimensions of the roller blind box over a length that lies in the range between the height dimension of one and two slats and a depth in the range between the height dimension of one and three slats can still be used quite advantageously in practical use.
  • the locking device for fixing the roller shutter box in its lowermost position has one or more locking pins which, in the case of locking, protrude with their ends into corresponding locking receptacle openings on the roller shutter box .
  • Such locking pins can easily z. B. in the frame of the associated window and operated from the inside of the room, so that when the roller shutter has reached the desired lower position, the operator concerned from the inside of the room through the frame into the corresponding receiving openings of the Roller blind box can be inserted.
  • these locking pins are designed as cable-operated spring pins, which brings a further considerable ease of use.
  • the locking pins can also advantageously be designed as spring catches, such spring catches being able to be fitted both in the roller blind box and in the window frame of the associated window, and the blocking receiving opening is in each case attached to the other of the two elements. If you have arranged the spring catch on the roller shutter itself, you can use it there again so that it either snaps in from the side or from below.
  • roller shutter according to the invention If you use a roller shutter according to the invention z. B. with a roller blind as pure sun protection or as a blackout, this can be done easily with the previously used side guide rails, which are provided for the roller shutters.
  • the roller shutter according to the invention is also to be used with an insect protection function, it is advisable to add an additional support for the small one at the bottom of the last one, in addition to the side guide rails To provide slats arranged fabric or lattice roller blind to ensure that an overlap between the guide rails and the fabric or lattice roller blind is reached and thus a lateral penetration of insects is effectively prevented.
  • the side guide rails are each U-shaped with two guide legs and an intermediate web connecting them, then it is particularly recommended for the purpose shown if the fabric or lattice blind is provided along each of its side edges with a profile that one of the guide legs associated lateral guide rail engages in a U-shape. This also ensures the desired overlap on the side of the lattice blind against undesired lateral penetration of insects.
  • brush or rubber piping can also be provided for this purpose on the side guide rails above their height, which are provided for contact with the two lateral end regions of the fabric or lattice roller blind that are pulled out of the roller blind box are. Such brush or rubber seals for the lateral sealing of the blind have proven to be particularly effective.
  • a further, particularly preferred and simple embodiment of the roller shutter according to the invention for effectively preventing an undesired lateral penetration of insects is that the side guide rails are provided over their height with contact strips for the lateral end regions of the fabric or lattice blind, these contact strips in the direction project to the inside of the window or door, thus towards each other, and accordingly cover it from behind with the roller blind pulled out in the corresponding end areas, so that it can be supported against these contact strips.
  • a particularly simple and preferred embodiment of the roller shutter according to the invention also consists in the roller of the fabric or lattice roller blind in the small roller blind box at the bottom of the last lamella of the roller shutter curtain in the form of a spring shaft, and this is preferably made of aluminum.
  • spring shafts are already used successfully in conventional insect roller blinds, are commercially available and therefore enable the roller shutter according to the invention to be designed particularly economically.
  • a hanging strip is particularly preferably provided, on which the free end of the fabric or lattice roller blind is fastened in a suitable manner and which in turn are positively attached to the last lamella of the roller shutter curtain can.
  • the innovative roller shutter in the event that the locking of the roller blind box can take place from the inside of the room, the possibility is given, even without opening the window or the door, the fabric or lattice roller blind in any desired position by pulling up the slats of the To move the roller shutter. If, when using the roller shutter according to the invention, the use of the fabric or lattice roller blind is not desired, then this can be easily moved up and down together with the roller shutter curtain and without performing its own function, thus "blindly", the concern being with the Underside of the tank, as already mentioned, is caused by the spring shaft.
  • the manufacture of the roller shutter according to the invention does not require much effort, it is simple and economical to manufacture and it is functionally reliable to the greatest extent.
  • roller shutters on the one hand or roller blinds or fabric roller blinds
  • operability from the inside of the room is also problem-free and even the assembly of the whole can be carried out with ease.
  • this basic inventive idea used in the roller shutters according to the invention namely the arrangement of a fabric or lattice roller blind at the bottom of the last slat of the roller shutter curtain with independent locking of its roller shutter box, even with existing roller shutters.
  • FIGS. 1, 3 and 5 lateral principle partial sectional views of a roller shutter according to the invention are shown, which is in the three figures in different positions: in Figure 1, the roller shutter is approximately half lowered, Figure 3 shows it in the fully lowered state and in FIG. 5 is, as will be described, the roller shutters being pulled back up to about half the height by partially pulling out the fabric or lattice roller blind attached to it below.
  • FIGS. 2, 4 and 6 show front views of the roller shutter positions according to FIGS. 1, 3 and 5, respectively.
  • the roller shutter shown in FIGS. 1 to 6 has an overhead roller shutter box 1, in which a winding roller 2 is arranged, on which the shell 3 of the roller shutter can be wound up or unwound.
  • a winding roller 2 is arranged, on which the shell 3 of the roller shutter can be wound up or unwound.
  • the winding roller 2 and the armor 3 are shown in principle, without the winding thereof on the roller 2 being shown in more detail in the drawing.
  • Figure 2 shows the roller shutter shown in Figure 1 in a basic front view.
  • Figures 1 and 2 show that the roller shutter curtain 3 consists of individual slats 4, the lowest, last slat (thus the slat at the free end of the roller shutter) is designated as slat 4 '.
  • a lattice or fabric roller blind 6 (to be selected depending on the particular desired application) is arranged on the last lamella 4 ′ and is wound on a spring shaft 7 in a small roller blind box 8.
  • the spring shaft 7 winds up under spring tension of the roller blind 6 as far as possible, whereby the roller blind box 8 of the lattice or fabric roller blind 6 is pressed against the underside of the roller shutter curtain 3.
  • the free end of the fabric or lattice roller blind 6 is fastened in a suitable manner to a hanging strip 27 (cf. FIGS. 5 and 6), which in turn is designed in the form of a special profile and is positively connected to the last slat 4 '.
  • a hanging strip 27 (cf. FIGS. 5 and 6), which in turn is designed in the form of a special profile and is positively connected to the last slat 4 '.
  • This can be done in the form that the profile of this hanging strip 27 on the top, on which the connection to the last slat 4 'is to take place, has the same or at least similar shape as the top of the individual slats, so that it is easier Just as the slats with each other on the underside of the last slat 4 'z. B. pushed laterally and thus can be positively attached to it.
  • roller shutter position of the roller shutter shown in FIG. 1 can be seen particularly clearly from FIG. 2: the armor 3 is lowered to approximately half the height of the window surface to be covered, the one hanging from below and through the action of the spring shaft 7 from below against the last slat 4 'pressed roller blind box 8 acts purely optically in the manner of an end lamella of the entire tank 3.
  • roller shutter shown in Figures 1 and 2 should be attached to a window, of which only in principle the frame 9 and the sash 28, in which the window pane 29 is seated, is shown in section. From Figure 2 it can also be seen that lateral guide rails 5 extend in the side of the roller shutter from the roller shutter box 1 arranged at the top to the bottom, in which the lateral ends of the shell 3 or the slats 4 are guided when opening or lowering.
  • FIG. 3 now shows the roller shutter shown in FIG. 1, but here the roller shutter armor 3 is completely lowered (see also FIG. 4) and the roller shutter box 8 for the fabric or lattice roller blind 6 rests on a window plate 30 at the bottom.
  • a locking pin 10 which is inserted from the inside of the room through the frame 9 of the window into a corresponding insertion opening 11 (see FIG. 7) in the blind box 8, the blind box 8 is locked in position in this lowest position.
  • FIG. 4 shows the position of the roller shutter from FIG. 3 in a top view from the front, whereby it can be seen that the roller shutter is here over its entire length Extension length L (see FIG. 2) is lowered.
  • the lattice or fabric roller blind 6 is guided upward over the entire height of the window, so that there is then a window opening which, from the outside, is exclusively from the lattice - or fabric roller blind 6 is covered. If the lattice or fabric roller blind 6 is now to be removed again (with the armor 3 still pulled up), the locking pins 10 only have to be pulled back into the frame 9 and thereby the position locking of the roller blind box 8 released, after which the Action of the spring shaft 7 rolls up the roller blind 6 in it and at the same time it moves upwards to the bottom of the last lamella 4 'of the tank 3.
  • a fiberglass fabric possibly also PVC-coated, can be used as the insect protection fabric for the roller blind 6, although other mesh or fabric fabrics can of course also be used, if desired.
  • the roller blind box 8 is not much greater in height than the height H of an individual lamella 4 of the tank 3 (cf. FIG. 2).
  • the roller blind box 8 it will be possible to design the roller blind box with a height that corresponds exactly to the height of such slats, so that from the outside a special uniformity of the optical image is ensured even when the tank is lowered.
  • FIGS. 7 to 9 now show, in a schematic sectional detail representation, various options for locking the roller blind box 8 in its lowest position:
  • a pin 10 is inserted through the frame 9 of the window into a corresponding locking or receiving opening 11 in the roller blind box 8.
  • two such locking pins 10 are provided over the length of the roller blind box 8, which, again preferably, are arranged symmetrically to the longitudinal center line of the roller shutter curtain.
  • the illustration according to FIG. 7 still shows in principle the fabric or lattice roller blind 6 running out of the roller blind box 8 and the spring shaft 7, which holds the roller blind 6 under spring pretension by means of a clock spring 12 which is only shown in principle in FIG.
  • a locking pin 10 ' is again used, which, however, is biased via a radial support collar 13 attached to it by means of a compression spring 14 in the direction of a blocking position extended from the frame 9.
  • the locking pin 10 ' is actuated via a cable pull 15, to which a deflection roller 16 is assigned in the illustration according to FIG. 8: this is only intended to illustrate in principle that the cable pull 15 to a particularly easily accessible for the operator by means of suitable deflection rollers or the like Actuation point can be performed.
  • Figures 10 to 14 still show some design options for sealing the sides of the fabric or lattice roller blind 6 in the event that it is to be used as an insect screen: this is to prevent insects from passing undesirably past the side edges of the roller blind 6 Window opening could occur.
  • the representations of FIGS. 10 to 14 are kept in principle and represent basic cross sections through the lateral guide strips 5 and the side area of the fabric or lattice roller blind 6, the sectional plane running perpendicular to the direction of movement of the roller shutter curtain 3.
  • the lateral area of the roller blind 6 overlaps in the illustration according to FIG. 10 with a corresponding contact strip 26, which consists of a lateral extension of the inner leg of the lateral guide profile 5.
  • a corresponding contact strip 26 which consists of a lateral extension of the inner leg of the lateral guide profile 5.
  • FIG. 11 Another solution is shown in FIG. 11, with U-shaped lateral edge profiles 23 being attached along the side edges of the roller blind 6.
  • U-shaped lateral edge profiles 23 are attached along the side edges of the roller blind 6.
  • This lateral U-shaped overlap profile 23 on the roller blind 6 can either consist directly of the fabric material of the roller blind 6 and be made in one piece with it: however, there is also the possibility here of suitable profiles 23 on the otherwise straight side edges of the roller blind 6 other materials (possibly even rubber or similar) to attach or fasten.
  • a small, only slightly wider side shoulder 31 is attached to the side of the lattice or fabric roller blind 6, which, when the roller blind 6 moves, between the innermost side web 21 of the corresponding side guide rail 19 and the Frame 9 runs or is even a little jammed there.
  • Figure 15 finally shows the roller shutters of Figures 1 to 6 in an intermediate position: here, the roller blind box 8 is only locked at a certain height on the guide rails 5, so that below the roller blind box 8 a part 32 of the roller shutter curtain that is not covered by the roller shutter 6 or the roller blind 6 Window is completely free and open.
  • a second partial surface, which is covered by the roller blind 6 extends only above the latter, and the rest of the window opening is then closed by the slats 4 of the roller shutter curtain.
