The invention relates to a device for the blind-like adjustment of roller shutter slats on the Guide rail by briefly pulling up and releasing the device for moving the Roller shutter, with the topmost of the adjustable rods giving its rotary motion to the ones below Rods as a guide rod transfers, with a guide pin protruding from a rod end in one of the Rotational movement correspondingly curved guideway slides. ίο

In one of the known devices of this type, a guide pin which can move transversely under spring pressure strives to move out of the guide rail of the roller shutter step out into the curved guideway, where he is hindered by a locking bolt, if he approaches the mouth of the guideway from above when lowering the roller shutter, while he moves the locking bolt so far up when approaching from below that it is resilient snap into the mouth of the guideway and with a small downward movement of the guide rod the Slide along the guideway and at the same time the guide rod with the rods attached underneath can adjust. However, this adjusting device is not free from disadvantages, which are mainly therein exist that the elements controlling the entrance opening of the curved guideway by accumulation can be blocked or jammed by dirt or dust, so that an adjustment, which then comes about when the guide pin of the guide rod along this guideway slides, becomes very difficult. Another disadvantage is that the adjustment of the guide rod, d. H. the downward movement of the same to produce the adjustment, very short and the time the beginning of the adjustment movement is not sharply delimited.

The invention is therefore based on the object of providing a device of the structure described design so that the disadvantages mentioned can no longer occur.

The invention consists in that the guide pin is steered when pulling up the roller shutter under the action of a deflecting means through a passage in one cheek of the guide rail into a deflecting guide path running parallel to this, from which when the roller shutter is further pulled up, it returns through an overlying passage the guide rail can slide, and that the curved guide path branches off from the deflection guide path, so that the guide pin when the roller shutter is released and under the action of means for adjusting the blind-like
of roller shutter slats

a deflection means is directed from the deflection guide track into the curved guide track.

According to a special proposal according to the invention, the guide pin is fixed at one end of the Arranged guide rod and the deflecting means acting on it is a flexible tongue at the bottom End of the cheek part near the lower passage, which protrudes into the guide rail.

An embodiment in which the guide pin is pivotable at one end is particularly useful of the guide rod is arranged and by a resilient deflection means against the outer cheek of the guide rail is printed.

An advantageous development of the invention is that the cheek part at the upper passage is extended by a resilient, protruding into the deflecting guide tongue, so that the guide pin probably slide out of the deflection track through the upper passage into the guide rail can, but not in the opposite direction.

An embodiment in which the deflection guide track is characterized by particular simplicity and the curved guideway is formed by slots in a plate. Furthermore, the Deflection means are expediently formed by two parts, namely one around a horizontal pin between two end positions pivotable arm with a hook attachment, the first end position near the junction of the curved guideway

As shown in FIG mark DA ends of a pair of links 6a with the two ends for, that the guide pin in.die Auslenkführungs- of the intermediate pair of links 6b. A path has entered and the roller shutter for the adjustment roller 10, which can roll in the guides 3 and its bars can be lowered, is produced. is between the two members 6 b of each. The advantages achievable by the invention are arranged in 20 pairs. The corresponding pivot pin 4 can be seen primarily in the fact that in the invention, through the members 6 a, 6 b, the hollow device a safe, pin 8 and the roller 10 existing part, which or jamming free guidance and Adjustment on the pivot 4 between a flange 11 of the roller shutter slats is achieved. In addition to the relief ring and an open, resilient ring 12, there is also a mounting in the actuation and improvement in FIG. The pivot pin 4 can rotate unhindered. The hollow pin 8 can load bars unhindered. In the following, the invention will be brought into engagement with one another or separated from one another to form only one exemplary embodiment.

Guide rails 3 and 3 are used for lifting and rail-mounted housing with the curved lowering of the roller shutter. A side view of the guide track and the Auslenkführungsbahn, front chains 13, the number of which can switch, 5 shows the in Fig. 4 dargestell- force the bars 2 to be adjusted to each other, th housing with the cover plate removed, 45 so that by the displacement of the deflection members 2 a all Fig. 6 is a view of the housing in section after others can also be adjusted. The chain links of the line VI-VI from F i g. 4, are designed as metal members 14, which at their F i g. 7 shows a section through the housing along the upper ends 15 in a T and at the lower end in line VII-VII from FIG. 4 on an enlarged scale, closed hooks 16 expire. The arms of the at the same time the end of the illustrated in Fig. 3 50 T-end 15 of each link 14 are pivotable th guide pin is shown, between the closed hooks 16 of the next Fig. 8 and 9 side views of two variants of the joint link mounted, with the exception of the first housing, the joint link of the chain, which is shown in a Kupp-F ig. 10 to 13, the adjustment system according to FIG. 8 and lung part 16 a is arranged, which is schematically pivoted part of the roller shutter during the 55 is inserted into the first rod. Each member 14 is different operating phases of the device via its closed hook 16 and hinged to a member 17, which in the corresponding roller shutter F i g. 14 the device according to FIGS. 4 to 7 rod 2 is embedded and screwed there with a screw 18 and schematically part of the roller shutter in one. As a result, all of the others become intermediate servicing phases. 5o Ren rods 2 in the one shown in Figs. 1 and 13 The roller shutter shown in Fig. 1 has two positions adjusted when the guide rod 2a is adjusted, types of horizontal, interlocking roller shutter and return as soon as the lifting action of the guide rod rods, namely non-adjustable roller shutter la stops under their own weight at the same time in rods 1 and adjustable roller shutter slats 2. The roller shutter slats 1 that are not back to their normal position, that is to say in the dashed position, connect the armor 65 in FIG. 10 to 12 and 14.

of the roller shutter with the upper roller, and the rod during the raising and lowering of the roller shutter ends run within guide rails 3, and the roller shutter switch is in the intermediate layers are arranged on both sides of the roller shutter. bars 2 due to their own weight in the nonna-

len, expanded position, as shown in FIGS. 10 to 12 and 14 is shown held. While the duration of these movements and in the intermediate layers of the roller shutter there is also no need to to adjust the rods. This need arises only when the roller shutter does so has been lowered so far that its staffs have not yet sunk into one another, a condition which hereinafter referred to as "semi-closed" and if more light and / or ventilation is required will. In order to adjust all the adjustable bars of a roller shutter, only a single one is required Rod to be adjusted, since the front chains 13 transmit the adjustment movement to all the other rods.

The in F i g. The embodiment shown in FIG. 2 shows arrangements for adjusting the uppermost guide rod 2 a. A curved holder 19 protrudes from the upper edge of each side end of this guide rod 2 a and runs out into the pivot 4. In addition, a straight guide pin 20 is provided on these side surfaces, which has an essentially triangular cross-section with straight side surfaces and a curved lower surface and rounded corners. For manufacturing reasons, the holder 19 sits with the pivot 4 and the guide pin 20 on a block 21 embedded in the guide rod 2a . One of the planes of the guide pin 20 runs essentially parallel to the central plane of the rod.

The in F i g. The guide rod shown in FIG. 3, which is made of sheet metal, has a "window" or an opening 23 in the vicinity of each end, which is formed by a part 22 which is bent inwards. At the same height as this opening 23 there is an opening 24 running in the end face of this rod and in the front face with the sections 24 & 24 ″. A movable guide pin 25 is articulated via a flattened end 26 to the inwardly bent part 22 of the rod via a screw 27 and protrudes outwardly from the rod through this angular opening 24. This guide pin 25 can move around the screw 27 at right angles to the center plane of the guide rod 2 a and is bent in its central part 25 a at the level of the front edge 28 of the angular opening 24, so that the end 25 & of the guide pin 25 through the section 24 b of the opening can protrude in a direction extending substantially parallel to the guide rod 2 a. On the other hand, but the part 25 a of the guide pin 25 abuts against the edge 28, so that the movement of the guide pin in the section 24 b of the opening 24 is limited. A spring 29 is arranged as a flexible deflecting means inside the guide rod 2 a, which spring forces the guide pin 25 to rest against the edge 28, so that the part 25 δ protrudes from the section 24 b of the opening 24.

In each of the two guide rails 3, a housing 30 is arranged at the same height as the guide rod 2a in the semi-closed state, of which in FIG. 1 only one was shown. This housing 30 has a lower part 31 and a plate 32 which are correspondingly connected to one another and to the guide rails 3. The guide rail 3 has a wide cheek 33, a narrower cheek 34 and a base 35 with longitudinal ribs 36 on the outer surface.

The narrow cheek 34 and the cheek part 34 a of the housing 30 form a guide track for both Guide pins. The cheek part 34 a of the cheek 34 and an edge 37 of a slot in the plate 32 of the housing 30 limit a deflection guide track 38. The guide rail 3 is with this deflection guide track 38 connected via a lower passage 39 and an upper passage 40. To make sure that the guide pins 20 (or 25)

ίο can slide into the deflection guide track 38, when the guide rod 2 a rises and reaches the lower "passage 39, which at this point of the guide rail 3 merges into the deflection guide track 38, deflection means are provided in order to the guide pins to act in the form of the spring 29 for the movable guide pin 25 and in the form of a resilient tongue 41 for the guide pin 20, this tongue 41 next to the lower passage 39 as an extension of the cheek

ao part 34 a of the outer cheek 34 of the guide rail 3 is formed and from this cheek 34 protrudes downwards and slightly inwards into the guide rail 3. Next to the upper passage 40, an elastic tongue 42 is provided, which from the cheek part 34 a upwards and something protrudes inwardly into the passage 40 so that the guide pins of the Auslenkführungsbähn 38 in the Guide rail 3 can slide, but not in the opposite direction.

In the lower part, the deflecting guide track 38 is extended by a curved guide track 43, which leads away from the guide rail 3. This curved guideway 43 is through stationary and / or movable arrangements for guiding the guide pins 20 or 25 limited. The stationary Guide devices are designed as a slot 44 in the plate 32. The upper edge 45 a of this slot 44 merges into the edge 37 of the deflecting guide track 38, and the plane of the slot 44 runs parallel to the base 35 of the guide rails 3 and to the lower part 31 of the housing 30. The movable deflection means is designed as an arm 46 which can pivot about the horizontal pin 47 and its Hook attachment 48 can move between two end positions, namely a first end position near the Branch point 49, at which the curved guide track 43 meets the deflection guide track 38, and a second end position at the end 50 of the curved guideway 43. In its first end position this arm 46 is pressed by a spring 51.

In addition, a deflection means designed as a resilient finger 52 is provided in the housing 30, whose free end 53 presses against the outer cheek 34 and a limitation for the deflecting guide track 38 forms at a contact point 54, which is located above the branch point 49 at which the curved Guide track 43 merges into the deflection guide track 38, this finger 52 from this Point 54 leads down through the Auslenkführungsbähn 38 to a foot 55, with the it is attached to the lower housing part 31.

In Figs. 10 to 13, the operation is the Device shown with a fixed guide pin 20. The non-adjustable roller shutter slats 1, the Guide bar 2 a and the adjustable roller shutter bars 2 near the same are shown in dash-dotted lines, while the guide rail 3 and the

housing are fully extended. When the roller shutter is lowered from its rolled up or open position (see FIG. 10), the end of the guide pin 20 slides along the outer cheek 34 of the guide rail 3 (see position 20 a in FIG. 10). When the guide rod la reaches the upper passage 40, the guide pin 20 runs past the elastic tongue 42, which prevents its entry into the first deflection guide track 38, whereupon it slides further down along the cheek part 34 "of the cheek 34 (see fig Position 20 in Fig. 10). He then runs past the tongue 41, which prevents him from entering the deflecting guide track 38 via the lower passage 39, and finally reaches a position in which (see position 20 & in FIG. 10) he is against the outer cheek 34 is present. The roller shutter slats can therefore not be adjusted while the roller shutter is being lowered from the rolled-up position.

When the roller shutter is now raised and the guide pin 20 reaches a position 20b under the lower passage 39 (FIG. 11), it is forced by the tongue 41 to enter this lower passage 39 so that it enters the deflecting guide track 38 until it reaches position 20 c of this web. When the roller shutter is raised further, the guide pin 20 can leave the deflecting guide track 38 via the upper passage 40, whereby it overcomes the pressure of the tongue 42. If, on the other hand, the roller shutter is lowered after the guide pin 20 has reached position 20c, the guide pin moves into a position 20d on the hook attachment 48 of the arm 46 (FIG. 12), whereupon it then moves into the curved guide track 43 enters, slides up to the end 50 and here assumes a position 20e in which it is furthest away from the guide rail 3 (FIG. 13). As shown in FIGS. 12 and 13 show, the guide rod la pivots out of the plane of the roller shutter when the guide pin is inserted into the Auslenkführungsbahn 38 20 and moves along the curved track 43. The remaining roller shutter slats 2 are adjusted at the same time. In order to move the roller shutter from the extremely adjusted, ie fully open position into any intermediate position and thus to change the inclination of the adjustable roller shutter slats, the roller shutter is only raised slightly until the desired intermediate position is achieved. When the roller shutter is then raised further, the guide pin 20 moves back along the curved guide track 43 and the deflection guide track 38 via the upper passage 40 into the guide rail 3.

The process is similar if the guide rod 23 has a movable guide pin 25 instead of the fixed guide pin 20, with the difference that this movable guide pin 25 does not require a flexible tongue 41 for the lower passage 39 (FIG. 9). On the other hand, the pivotable arm 46 can be omitted with each embodiment of the guide pin 20 or 25. If this arm is omitted, the slot 44 with the curved guide track 43 and the edges 45 a, b forms the guide pin conductive arrangements, the edge 45 a in function while the roller shutter is raised from the adjustment position to the semi-closed position and where the edge 45 & serves as a guide while the roller shutter is being lowered to adjust the roller shutter slats. In the embodiments in which the pivotable arm 46 is provided in the housing 30, the edge 45 & does not serve as a deflection means.

As shown in FIGS. 4 to 7 and 14 can be seen, the housing 30 has a resilient, resilient Finger 52 up. One function of this is to guide the guide pin 20 or 25 into the curved path 43 lead, but its main function is to give the cheek portion 34 a hard, hammer-like To offset blow when the guide pin 20 or 25 between the cheek 34 and the free end of the finger 52 (fully marked in FIG. 14) in the position immediately above it (position 20 c in Fig. 14) slides, so that an audible signal sounds when the guide pin in the deflection track 38 has slid and the roller shutter can be lowered to adjust the roller shutter slats.
