Description

I. Field of application

The present invention relates to a rolling grille or roller door with a rollable Door for closing garages, passages etc.

II. Technical background

There are installation situations for such rolling grilles or rolling gates, where little side space is available that next to the rolling grille or rolling gate no more slip, escape or panic doors. In these cases a wicket or escape or panic door directly in the rolling grille or rolling gate be provided yourself.

If doors are provided directly in rolling grilles or rolling gates themselves, then it is necessary that such doors together with the rolling grille or roller door can be rolled up and are accordingly flexible. This requirement means that the doors provided in rolling grilles or rolling gates are inadequate Dimensional stability and bending stiffness against loads perpendicular to Show door level.

In order to remedy this lack of dimensional stability and flexural rigidity, Rolling grilles and rolling gates developed, which have rollable doors, which in the developed or lowered state of the rolling grille or roller shutter with construction parts to be attached by hand, e.g. B. stiffening profiles, have to be lined. Before rolling grilles or rolling gates with such stiffened doors can be wound up, the additional Construction parts can only be removed as they are not around the tubular shaft of the rolling grille or roller shutter. This extra effort is undesirable and in particular it is sometimes forgotten the extra Removing construction parts, which is then when opening or winding the Rolling grilles or rolling gates both on the latter and on the construction parts can lead to damage or destruction.

III. Presentation of the invention a) Technical task

It is therefore the object of the present invention, a rolling grille or roller door to create with a rollable door, which without the installation of additional stiffening Construction parts have sufficient dimensional stability and bending stiffness having.

b) solving the problem

This task is accomplished using a rolling grille or roller shutter with the features of claim 1, claim 7 or claim 12 solved. Further Embodiments of the three embodiments according to the invention result from the subclaims.

It is the first embodiment proposed according to the invention is a rolling grille or roller door with a door, which is made of a folding structure exists, which can be opened and closed like an accordion. At This embodiment is a in the door opening of the rolling grille or roller shutter Integrated door, which can be rolled up together with the rolling grille or roller door, whereby the door has at least three door sections which are connected to one another in an articulated manner are, the first door section articulated on one side of the door opening and the last door section consists of at least several locking elements, which engage in corresponding bolt receptacles when the door is closed, which are provided on the other side of the door opening, creating the door is held dimensionally stable in the rolling grille or roller shutter.

The door should fit into the overall picture of the rolling grille or roller shutter, which is at the former of a transparent lattice construction and the latter of of a non-transparent lamella construction. This means that the individual door sections whose height is substantially the same the height of the door opening is, in the case of a rolling grille, from a corresponding one Lattice bar construction and in the case of a roller shutter from a corresponding one Slat construction exist. The last one or in the case of exactly three door sections third door section does not have to be the same width as the rest Have door sections, but it can also be made exclusively from the Latch elements exist, which are then directly on the adjacent side End of the penultimate or, in the case of exactly three door sections, the second Door section are articulated. The width of the last or third door section in this case corresponds approximately to the length of the locking elements and is much smaller than the widths of the other door sections.

The advantage of the rolling grille or roller shutter according to the invention is that the locking elements provided on the last door section into the corresponding Interlock bolt receptacles, which form-fit the free end of the door the quasi-fixed area of the rolling grille surrounding the door opening or roller doors is connected so that the closed door keeps its shape in the entire rolling grille or rolling gate is integrated. The locking elements are preferably evenly along the free side of the last door section distributed. The folding construction according to the invention does not interfere in any way Way the roll-up of the integrated door, since the latter in its basic Construction of the construction of the remaining area of the rolling grille or roller shutter corresponds. Without the design of the door according to the invention, this could at least in the area closer to the free end of the door can be bent out of it by applying slight pressure perpendicular to the door plane. Exactly this undesirable flexibility of the door was according to the state of the Technology suppressed with the help of additional construction parts.

To lock the door or to prevent unauthorized access at least one lock device can be provided, with the help of which at least the articulation between the first and the second Door section can be blocked. Such a blockage is, for example caused by a pin or bolt that normally goes into the two against each other movable members of an articulated ligament element is pushed.

To simplify the insertion of the locking elements into the locking receptacles the last or third door section can be moved linearly in the door plane be led. For this purpose, the upper limit of the door opening from one Profile rail are formed, for example, a C-profile open at the bottom and in which trolleys run, which at the top of the last or third door section are attached and hold it. Furthermore, additionally or alternatively in one at the free end of the rolling grille or rolling gate located end rail a guide groove are provided in which Trolleys run with the bottom of the last or third door section are connected and support it.

The roll-up doors provided in rolling grilles or roller doors differ one after wicket doors on the one hand and escape or panic doors on the other. Wicket doors are those doors through which a person can pass under normal conditions can go through in peace. Escape or panic doors are however, are doors that meet the fire protection requirements have to. These requirements include, for example, that none are dangerous Tripping hazards may be present, which are common in the event of an emergency Inattentiveness to be observed to overturn those passing through the doors in question Can lead people with fatal consequences.

According to the invention, the requirements for an escape door are met by that a terminated rail is provided in the area of the door opening and a separate end rail piece at the lower end of the last or third door section is articulated, which in accordion-like Opening the door in one part of the interrupted end rail telescopic is. This telescopic design requires that the separate End rail piece has slightly smaller cross-sectional dimensions than the rest of the end rail. That the last or third door section assigned end of the separate end rail piece engages in the closed Condition of the door in the other part of the end rail.

According to the invention, a second embodiment is proposed, the one in which Rolling grille or roller door integrated door is a swing door construction. The in the In this second embodiment, the door opening integrated door only has one only door segment, which is only articulated on one side of the Door opening is stored and otherwise - in contrast to the first embodiment - is not provided with any other articulated connections. The individual At its free end, the door segment has a plurality of locking elements which are movable between an open position and a closed position, wherein the locking elements in the closed position in corresponding locking receptacles engage, which are provided on the other side of the door opening, whereby the door is kept dimensionally stable in the rolling grille or roller shutter.

According to the invention, the second embodiment also has the advantage that that a dimensionally stable connection between the door on the one hand and the On the other hand, the door opening surrounding area of the rolling grille or roller shutter is achieved. The rotary wing construction according to the invention affects in no way the rollability of the integrated door, since the latter in its basic Structure of the construction of the remaining area of the rolling grille or Corresponds to rolling gates.

An actuating device is preferred in the second embodiment provided that the simultaneous movement of the locking elements between the Open and closed positions enabled. Such an actuator can in particular a horizontally movable first link strand have, of several articulated links consists. The locking elements are attached to some of these links. A second Link strand, which also consists of several hinged together There is a link and is closer to the free end of the door segment than the first Link strand, used to guide the locking elements. By horizontal Move the first link strand towards the bolt receptacles the bolt elements are inserted into the bolt receptacles and thus the Dimensionally stable connection desired according to the invention between the door segment and the remaining area of the rolling grille or roller shutter. The first link strand can by means of spring elements, the number of which is preferably that corresponds to the locking elements, biased into the open position of the locking elements become. The spring elements are supported on the one hand on the not in the door level movable second link strand and on the other hand on the first Link strand from.

1 shows the overall view of a rolling grille 1 or 1 'according to the invention, which is shown in the closed or unwound state and locks a garage or a passage, for example. With the help of Pipe shaft 18, which is rotatably mounted in the masonry 19, the rolling grille 1 together with the integrated door 2 or 2 'and the continuous end rail 10 wound up and thereby opened.

The rolling grille 1 or 1 'consists of a plurality of grille bars 21 which are located above the integrated door 2 or 2 'continuously across the entire width of the rolling grille 1 or 1 'and in the area below from the door opening are interrupted. The integrated door 2 or 2 'also consists of bars 21, so that it fits optically into the overall picture of the rolling grille 1. The bars 21 are held together by means of several link strands 22, which are each composed of several articulated links. The bars 21 each form the hinge axes around which the individual links of the link strands when winding up the rolling grille 1 or Turn 1 '. The vertical distance between two bars 21 corresponds approximately the length of a link of the link strands 22. By the two of each Linking two link strands 22 and two bars 21 limited rectangular areas the rolling grille 1 can be seen through.

The individual links of the link strands 22 of the integrated door 2 or 2 'correspond depending on the embodiment, that of the remaining area of the rolling grille 1 or differ. The door 2 of the first embodiment is with link strings 22 provided differently than the door 2 'of the second embodiment, in which the link strands 22 essentially that of the rest of the area correspond to the rolling grille 1 '.

Fig. 2 shows the first embodiment of the integrated door 2 of the invention Rolling grille 1, but not for the purpose of clarity all bars and links were drawn. The door 2 consists of a total of 3 door sections 3, 4 and 5, each of which consists of one Lattice bar construction with bars 21 exist.

2A, which is the sections A-A indicated in FIG. 2 the bars 21 of the first door section 3 with the aid of an articulated hinge 23, which is also known as the so-called "piano band", articulated with the Link strand 24 connected, which forms the right side of the door opening. Thereby the link strand 25 of the door section 3 is hinged to the link strand 24. As can also be seen in FIG. 2A, the hinge band 23 is seated in the viewing direction of FIG Fig. 2 relatively far back, so that the door section 3 from the rear 2 is pivotable away.

FIG. 2C shows the detail "C" identified in FIG. 2 in an enlarged manner Scale. It can be seen how the individual bars 21 in the holes the links of the link strands 24 and 25 sit around an articulated connection to ensure between the door section 3 and the link strand 24.

The articulated connection between the gate section 4 and the gate section 5 takes place in the same way as the articulated connection between the gate section 3 and the link strand 24, as can be seen in FIGS. 2 and 2A Link strands 26 and 27 show. That the articulation between the Door section 3 and the door section 4 causing hinge 28 is arranged according to Fig. 2B, which shows the section marked in Fig. 2 B-B. Here the hinge band 28 sits relatively far forward in the viewing direction of FIG. 2.

2D shows the detail "D" marked in FIG. 2 in an enlarged manner Scale. One link of link link 29 or 30 can be seen in each case, it is also shown how the respective associated bars 21 in the holes of the respective links. The one that acts as a locking element Bolt 6 is fastened in the central region of the limb of the limb strand 29 and accesses the dimensionally stable connection of the door section 5 with the left side of the Link line 30 delimiting the door opening in the central area of the associated Link arranged bores 31, which as bolt receptacles to serve. If the link strand 29 of the door section 5 in Fig. 2 to the right moves, the bolt 6 moves with and comes with respect to the holes 31st disengaged. The bolts 6 are preferably evenly along the Link strand 29 distributed. It is not necessary to link every limb of the limb 29 to be provided with a bolt 6.

FIG. 2E shows the section E-E identified in FIG. 2, in which it can be seen that that the door opening is limited by a profile rail 9. She points a C profile open at the bottom, in which two trolleys 32 and 33 can move linearly. The trolley 32 holds the door section 5 in the area of Hinge 34, while the trolley 33, the door section 5 in the area of Link strand 29 holds. The trolleys 32 and 33 thereby ensure a Linear guidance of the door section 5 in the door plane.

In Fig. 2 is also a continuous end rail 10 of the Roll grille 1 can be seen. It has a guide groove in the area of the door opening 11, whose length corresponds approximately to the width of the door opening and in which the trolleys 35 and 36 can move linearly. Trolleys 35 and 36, respectively support the lower area of the door section 5, for example on the hinge 34 or on the link strand 29.

Fig. 3 shows schematically the mode of operation of the door 2 of the first embodiment, which is constructed as a folding structure. The arrows P ₁ and P ₂ indicate an opening movement of the door 2. It can be seen how the door sections 3 and 4 lay in concertina-like fashion, while the door section 5 is guided linearly in the door plane according to the arrow P ₂ until the hinge hinge 34 meets the hinge hinge 23 in the fully open position. In the open position, the door section 5 still blocks an area of the door opening corresponding to its width. The door section 5 is therefore preferably chosen to be as narrow as possible. In particular, it can only consist of the bolts 6 which act as locking elements, that is to say they do not have their own bars 21.

A lock device can be used to secure door 2 against unauthorized opening 8 are provided, which can be seen in Fig. 2 and the articulation blocked between door sections 3 and 4. If necessary, along the Articulated straps 28 and 34 also arranged a plurality of lock devices 8 become.

FIG. 2F shows the section F-F identified in FIG. 2, in which it is shown like a locking bolt 37 of the locking device 8, the articulation blocked between door sections 3 and 4. As shown additionally in Fig. 2, is alternatively also arranged in the central region of the door section 4 Panic or rod lock 44 conceivable, which between the hinge straps 28 and 34 is arranged and the rods of which when actuated in opposite directions Moving directions and at the same time the articulated connections block between door sections 3 and 4 as well as 4 and 5. If necessary several rod locks 44 can also be provided.

Fig. 4 shows the lower area of the door 2, which in this form can also be recognized as an escape door. In a departure from FIG. 2, the rolling grille 1 here has an end rail 20 which is interrupted in the region of the door opening. An end rail piece 12 is fastened via a joint 38 to the lower end of the door section 5. When the door 2 is closed, the left end of the end rail piece 12 projects a little into the left part of the end rail 20. The right end of the end rail piece 12 also projects into the right part of the end rail 20. If the handle located in the area of the lock device 8 is pressed in the viewing direction of FIG. 2, the door 2 opens and the door section 5 pushes the end rail piece 12 according to arrow P ₃ into the hollow profile of the right part of the end rail 20. It is therefore not a dangerous one Trip edge more available.

5 shows the second embodiment of a rolling grille 1 'according to the invention, in which the integrated door 2 'is a swing door construction. The door 2 ' consists of a non-articulated door segment 3 ', which in the same Way as the door section 3 of the first embodiment on the link strand 24 'is articulated. Fig. 6A shows the corresponding hinge 23 ', which is arranged between the link strands 24 'and 25'.

A major difference between the swing wing construction on the one hand and the folding construction, on the other hand, is that the locking elements 6 'are not automatically when the door 2 'is closed into the bolt receptacles 7' of the link strand 30 'intervene. Therefore, the locking elements 6 'are horizontally movable trained so that they between an open and a closed position can be moved. 5, the open position is shown.

The actuator for moving the locking elements 6 'of the Open- in the closed position has a handle 39 ', with the help of which a first link strand 13 'in Fig. 5 can be pushed to the left. The individual links of the first link strand 13 'slide on the individual Lattice bars 21 '. Since the locking elements 6 'on the first link strand 13' are fastened, they move together with the first link strand 13 ' to the left. A second is for linear guidance of the individual locking elements 6 ' Link strand 15 'is provided, which is immovable within the door plane and the links 16 'guide bores for guiding the locking elements 6' exhibit. If the handle 39 'is moved sufficiently far to the left, grip it the locking elements 6 'in the corresponding locking receptacles 7' and provide the dimensionally stable connection desired between the free lateral end of the door segment 3 'and the link strand 30' forth.

As can already be seen in Fig. 5, the first link strand 13 'can Spring elements 17 ', in particular compression springs, biased into the open position become. The spring elements 17 'are based on the one hand Links 14 'of the first link strand 13' and on the other hand on the links 16 'of the second link strand 15'. The indented in the bolt receptacles 7 ' Position of the locking elements 6 'can counter to the spring force of the spring elements 17 'can be held by, for example, one which moves with the handle 39' Locking rod (not shown) from one located in the lock 40 ' Pawl (not shown) is blocked.

5 it can also be seen that those locking elements 6 ', which are located immediately above and below the handle 39 ', are longer than the other locking elements 6 '. Such extended locking elements 6 'bring about an additional stiffening of the Door segment 3 '.

Fig. 6B shows the section B-B marked in Fig. 5, in which a link 14 'of the first link strand 13' and a link 16 'of the second link strand 15 'can be seen. The links 14 'and 16' have a U-shaped cross section on. The spring element 17 'is supported with its left end on the inside of the left U-leg of the link 16 'and with its right end at the Outside of the left U-leg of the link 14 '. Accordingly, in right U-leg of the link 16 'provided a sufficiently large bore, which allows the spring element 17 'in addition to the locking element 6' runs through it.

Fig. 6B further shows the S-shaped cross section of the handle 39 'that it allows the actuator to operate the door 3 'from both sides can be. To stiffen the link strands 13 'and 15' against bending stresses in the door plane there is one in each of the link strands 13 'and 15' Spring steel 41 'inserted between the individual locking elements 6' and U-webs of the links 14 'and 16' of the link strands 13 'and 15' runs. Of the Spring steel 41 'is perpendicular to the door plane in relation to bending stresses sufficiently soft that it can be rolled up together with the door 3 ' and does not have to be removed before winding up the rolling grille 1 '.

In Fig. 6C, the detail "C" indicated in Fig. 5 is on an enlarged scale shown. Next to the link line forming the left boundary of the door opening 30 'are three links 14' of the first link strand 13 'and three links 16 'of the second link strand 15'. The individual links of the Link strands are each tapered at their upper end to fit into each to be able to engage the lower end of the link above. About that in addition, the two elongated locking elements 6 'are in the form of locking bars and the two associated spring elements 17 '. The bolt receptacles 7 'are here each of a hole in the right U-leg of the Links of the link strand 30 'formed. It is easy to see that the Lattice bars 21 'when rolling up the rolling grille 1' the joint axes of the individual Form links of the link strands and the locking elements 6 'together with the individual links about these joint axes.

Fig. 7 illustrates schematically the operation of the rotary wing construction. In contrast to the folding construction, the door segment 3 'executes a simple pivoting movement around the hinge 23' according to arrow P ₄ .

In the second embodiment, too, the door 2 'can be recognized as an escape door be formed. For this purpose, the end rail is in turn in the area of Door opening interrupted and a separate connecting rail piece articulated on attached lower end of the door segment 3 '. When the door 2 'is opened, this pivots Connection rail piece together with the door segment 3 'according to FIG. 7 away, so that there is no more stumbling edge. To grind the end rail piece to avoid at the bottom, the cross section of the same is preferred not quite as high as that of the other end rail, so that a sufficient distance from the floor is kept in the area of the door opening can be.

Figures 8A to 8D show different types of links of the individual link strands the first and second embodiments described above. The figures show the links in a view parallel to their two U-legs as well as to the left in the associated side view from the right.

8A shows the link with the bore 7 'which acts as a bolt receptacle, which is used among other things in the link strand 30 '. 8B shows a Link 16 'of the second link strand 15', the one in the right U-leg hole is larger than that in the left U-leg, because of the larger bore must also pass through the spring element 17 '. Fig. 8C shows a link 14 'of the first link strand 13' and in FIG. 8D is one ordinary link, not modified with additional holes, which with the bores 42 and 43 receiving the bars 21 and 21 ' is provided and is used for the link strands 22. Depending on your needs the links according to FIGS. 8A and 8C naturally also in the link strands 30 and 29 of the first embodiment apply.

In the unrolled or unwound shown Position, the rolling grille 1 ″ closes the one present in the wall 19 Opening. With the help of the tubular shaft 18, which is rotatably mounted in the masonry 19, the rolling grille 1 '' including the integrated door 2 '' can be wound up and thereby be opened.

The structure of the link strands 22 ″ and the bars 21 ″ correspond those of the first or second embodiment. In particular sit down the link strands 22 '' together from the links according to FIG. 8D.

The door 2 '' has a door segment 3 '', the left side of which with the help of a Articulated hinge 23 '' is articulated to the rolling grille 1 ''. The ligament 23 '' corresponds to that according to FIGS. 2A and 6A. The door 2 '' is facing 9 opened.

The rolling grille 1 ″ consists of an upper grating section 59 and one lower grid section 60. At the lower end of the upper grid section 59 a first center rail 62 is provided while the lower grid section 60 is on has a second middle rail 63 at its upper end. The middle rails 62 and 63 are by means of an articulated spring band, a so-called bomber band, connected with each other. The second center rail 63 is thereby stabilized.

The door 2 '' integrated in the rolling grille 1 '' is completely in the lower one Grid section 60. The door 2 ″ in particular has the same height as that lower grid section 60. The second middle rail 63 is therefore at the location of the Articulated hinge 23 '' interrupted and her in the area of the door opening Part swings away with opening door 2 ''. At the bottom of the lower grid section 60 is a first end rail 64, which is interrupted at the point of the hinge 23 ". You in the area of the door opening located part swings away when the door 2 '' is opened. Should the door be 2 '' Escape door function, so the first end rail 64 forms the end of the Roll screen 1 '' at the lower end. When the door 2 '' is open, the Door opening therefore no tripping edge. Is a wicket door in the rolling grille 1 '' sufficient, so a second end rail 64 can be on the first end rail 65 are provided, which over the entire width of the rolling grille 1 '' runs continuously.

In FIG. 9 two tension springs 58 can also be seen which the door 2 ″ in press their closed position, i.e. out of the plane of the drawing. The one the tension springs 58 is arranged on the second central rail 63 while the another of the tension springs 58 is provided on the first end rail 64. One end of the tension springs 58 acts on the door 2 ″ during this other end is attached to the remaining part of the rolling grille 1 ''. Either the tension springs 58 and the hinge spring band 61 can be covered if necessary become.

9 shows the guide device 50 which is supported in relation to the walls 19 to recognize. It preferably extends over almost the entire height of the Roll grating 1 '' or the opening in the wall 19. The right ends in Fig. 9 the bars 21 ″ protrude into the guide device 50. The number and Distribution of the lattice bars 21 'projecting into the guide device 50 via the height of the door 2 '' can be varied from case to case.

Fig. 10 shows the section A-A marked in Fig. 9. In the right half of the 10 shows the masonry 19 on which two angle profiles 66 and 67 are attached. Between the two protruding from the masonry 19 Legs of the angle profiles 66 and 67, a lock 54 is arranged. The in Fig. 10 lock latch, not shown, can be moved by actuating the trigger 68 become. The lock bolt 55 is turned on or off using an associated key. extended. To implement the movement of the pusher 68 or the key in a corresponding movement of the lock latch or lock bolt 55 a suitable reversing gear is provided in the lock 54. At the castle 54 is a panic or a conventional latch change lock. If the door 2 ″ is to function as a wicket door, the lock 54 is preferred operated by means of a rotary knob. However, if it should act as an escape door, then the lock 54 designed as a panic lock, preferably by means of the handle 68 operated.

At the left end of the leg of the angle profile 67 protruding from the masonry 19, a hollow profile rail 50, which acts as a guide device, is fastened. It has a U-profile open towards the door 2 ″ and preferably extends over almost the entire height of the rolling grille 1 ″ or the opening to be closed in the wall 19. The hollow profile rail 50 can also have other profiles, provided that they are Leadership function, ie their holding effect in the direction R ₁ (inwards) and in the direction R ₂ (outwards) is guaranteed.

The hollow profile rail 50 consists of a first rail leg 51 and a second rail leg 52. The first rail leg 51 in turn has an essentially U-shaped cross section and is fastened to the angle profile 67. The second rail leg 52 has an essentially L-shaped cross section and is articulated to the first rail leg 51 by means of the hinge strap 69. It can thus be pivoted according to arrow R ₃ in a clockwise direction from its holding position shown in FIG. 10, in which it holds the lattice bars 21 ″ of the door segment 3 ″ in the hollow profile rail 50, into its open position, in which it moves the lattice bars 21 '' and thus the door 2 '' in the direction R _{2 is} no longer hindered, that is to say there is no longer any holding effect and thus the door 2 '' can be opened to the outside.

The pivotable rail leg 52 extends over the entire height of the Hollow profile rail 50. However, it is also conceivable that the pivotable Rail leg 52 extends only over the height of the door 2 ''.

About the pivoting movement of the rail leg 52 into its open position to be able to prevent a blocking device 53 is provided. It is from the lock 54 including the latch and bolt 55 and the locking bar 56 are formed, which is welded to the rail leg 52. The locking bar 56 preferably extends over the entire height of the rail leg 52, but can also be made much shorter, namely only in the area of the lock 54. As can be seen in FIG. 10, the extended bolt 55 in the movement path along which the Locking bar 56 moves when the rail leg 52 moves clockwise turns. The extended bolt 55 thus blocks the pivoting or rotating movement of the rail leg 52 in its open position. The same applies to the extended latch of the lock 54, not shown in FIG. 10.

In the left half of FIG. 10 are the lattice bars tapering to the right 21 '' of door 2 ''. At the tapered ends of the bars 21 '' Guide elements 57 are provided, which for guiding the bars 21 '' in the hollow section rail 50 should provide as little play as possible. Both Guide elements 57 can be rotatably fixed with the bars 21 '' connected bodies with square, rectangular, circular cylindrical or act in a similar cross-sectional shape. However, it is also conceivable for guide elements 57 in the form of rollers rotatably mounted on the bars 21 ''.

In the position shown in FIG. 10, the door 2 ″ is in the closed state. The first rail leg 51, in conjunction with the angle profile 67 supported on the masonry 19, prevents the door 2 ″ from opening in the first direction R ₁ or inwards. In conjunction with the blocking device 53, the second rail leg 52 prevents the door 2 ″ from opening in the second direction R ₂ or to the outside. If the door 2 ″ is to be opened to the outside, the bolt 55 of the lock 54 with the associated key must first be inserted. The latch of the lock 54 can then also be retracted by actuating the pusher 68. The movement path of the locking bar 56 is then no longer blocked. Now the door 2 ″ can be pressed outwards in the direction R ₂ , so that the guide elements 57 press against the rail leg 52 and turn it clockwise according to arrow R ₃ into its open position. Nothing stands in the way of opening the door.

If the door 2 '' is then to be closed again, it is first opened in the rolling grille level pivoted back so that the free ends of the bars 21 '' together with guide elements 57 are again in the hollow profile rail 50. Then the rail leg 52 is finally from its open position to move back to its stop position shown in FIG. 10. This can happen, for example, from the inside through the bars 21 '' reached through and that which extends at least over the height of the door 2 ″ Rail leg 52 is pressed by hand into the holding position. Finally can the retracted before pivoting the rail leg 52 The case of the lock 54 is extended again by releasing the push button 68 become. In addition, a lock by extending the Riegel 55 take place.

To reach through the bars 21 '' from the outside inwards and one to avoid possible actuation of the handle 68 from the outside, the Door 2 '' in the height of the lock 54 on a penetration protection, which from a plurality of securing bars 70 arranged between the bars 21 ″ exists, as can be seen in FIG. 9. Even if such a penetration protection is provided, can be used to pivot the rail leg back 52 in its holding position above or below the securing rods 70 can be reached through the bars 21 ''

However, in order to also pivot the rail leg 52 in in a more comfortable manner a resetting device can be provided to enable its stop position become. This reset device exists in the embodiment shown from a reset bolt 71 slidably mounted in the angle profile 67, whose front end abuts the locking bar 56. When moving the Rail leg 52 in the open position pushes the locking bar 56 the reset pin 71 when viewed in Fig. 10 down, i.e. inside, out of the angle profile 67. If the rail leg 52 of his Open position can be pivoted back into the holding position, so the reset bolt 71 when viewed in Fig. 10 by hand upwards, i.e. after outside, pressed, causing him the locking bar 56 and thus the rail leg 52 swings back counterclockwise. To secure the Reset bolt 71 in the angle profile 67 can be in the front area A securing means, not shown in FIG. 10, for example a securing ring, be provided. The safety bolt 71 falls out the angle profile 67 is thereby excluded.

The three embodiments of the invention were based on the example of a rolling grille explained. In the case of a roller shutter, only the bars are passed through Roller shutter profiles or slats replaced.
