Description

I. Field of application

The present invention relates to a rolling grille or roller door arrangement with a roll-up door for closing garages, passages, etc.

II. Technical background

There are installation situations for such rolling grilles or rolling gates in which there is so little lateral space that next to the rolling grille or rolling gate there is no more slip or escape or panic door. In these cases, a slip or escape or panic door must be provided directly in the rolling grille or rolling gate itself.

If doors are provided directly in rolling grilles or rolling gates themselves, it is necessary that such doors can be rolled up together with the rolling grille or rolling gate and are accordingly flexible. This requirement leads to the fact that the doors provided in rolling grilles or rolling gates have insufficient dimensional stability and bending stiffness against loads perpendicular to the door plane.

In order to remedy this lack of dimensional stability and bending stiffness, rolling grilles and rolling gates have been developed which have rollable doors which, in the unwound or lowered state of the rolling grille or rolling gates, have construction parts which can be attached by hand, such as, for. B. stiffening profiles must be lined. Before rolling grilles or rolling gates can be wound up with such stiffened doors, the additional structural parts must first be removed again since they cannot be wound around the tubular shaft of the rolling grille or rolling gate. This additional effort is undesirable and in particular it is sometimes forgotten to remove the additional structural parts, which can then lead to damage or destruction of both the latter and the structural parts when opening or winding up the rolling grille or rolling gate.

From US 5,673,740 a roller door arrangement with a door opening for closing openings in walls is known, the door opening being arranged on one of the side edges of the roller door, a door integrated into the door opening being provided, which can be rolled up together with the roller door and from a single one Door segment exists, which is articulated on the roller door, and a guide device which can be supported with respect to the walls is provided for guiding the door segment when it is rolled up.

Since the door integrated in the roller door in the closed state only rests with the free end on a projecting section of the guide device forming a stop, there is a risk, in particular when the roller door is rolled up, that the door opens and with its upper edge of the door against the underside of the roller box is pressed. A fixation of the door relative to the guide device, for example by means of a conventional door lock, is not necessary since the door must remain movable relative to the guide device in order to roll up the roller shutter.

III. Presentation of the invention a) Technical task

It is therefore the object of the present invention to provide a rolling grille or roller door arrangement with a roll-up door, in which the door can be locked in the closed state by means of the guide device and nevertheless can be moved in the guide device in the locked position to roll up the entire rolling grille or roller door ,

b) solving the problem

This object is achieved by means of a rolling grille or roller door arrangement with the features of claim 1. Further refinements of the embodiment according to the invention result from the subclaims.

According to the invention, a roller grille or roller shutter arrangement with a guide device is proposed, the door integrated in the roller grille or roller shutter being a rotating leaf construction. The rolling grille or roller shutter with a door opening is used to close openings in walls. The door opening is arranged on one of the side edges of the rolling grille or rolling gate and a door is provided which is integrated into the door opening and which can be rolled up together with the rolling grille or rolling gate. The door consists of a single door segment, which is articulated on the rolling grille or roller door and which engages with its free end in a guide device supported with respect to the masonry. This guide device has a first guide means with a holding action in a first direction perpendicular to the rolling grille or rolling gate plane and a second guide means with a holding action in a second direction, which is opposite to the first direction, the second guide means being movable from its holding position into an open position in which it has no holding effect. The movement of the second Depending on the design of the guide device, the guide means can be a pure rotary or swivel movement, a pure linear or translational movement or a superimposed rotary and translational movement.

The advantage is that the free end of the integrated door is kept dimensionally stable in the guide device. A connection of the free end of the door to an area of the rolling grille or rolling gate surrounding the door opening is not necessary, so that no additional locking elements have to be provided on the door. The rotating wing construction according to the invention does not in any way impair the rollability of the integrated door, since the basic structure of the latter corresponds to the construction of the remaining area of the rolling grille or rolling gate.

Since the guide device naturally has to be supported in relation to the walls in which the opening to be closed with the rolling grille or rolling gate is located, only two arrangements of the integrated door can be considered, namely an arrangement of the door on the right and / or on the left side edge of the Rolling grilles or rolling gates. In order to ensure as little play as possible between the guide means of the guide device on the one hand and the ends of the roller grille bars or roller shutter slats engaging in the guide device, guide elements can be arranged on the free ends of the roller grille bars or roller shutter slats. Preferably, all rolling grille bars or roller shutter slats should engage in the guide device. However, it is also conceivable that only every second rolling grille bar or every second rolling door slat engages in the guide device. In addition, any other distributions of the rolling grille bars or roller shutter slats engaging in the guide device can be selected along the free end of the door segment.

The integrated door is opened by pressing the door segment in the second direction. As a result, the second guide means of the guide device moves from its holding position which develops the holding action into its open position. To prevent unauthorized opening of the door, a blocking device can be provided, by means of which the path of movement of the second guide means between the Stop position and the open position can be blocked. When the second guide means is blocked, the holding effect of the guide device is retained both in the first and in the second direction. A lock is preferably selected as the blocking device, the latch and / or bolt of which can block the movement path of the second guide means. If the lock bolt is in its retracted position and the lock latch is in its extended position, in which it blocks the path of movement of the second guide means, the door can be opened at any time by actuating an associated door handle or knob, which is connected to the deflection gear provided in the lock Lock latch is transmitted, and then pressing the door segment in the second direction to be opened. If not only the lock latch, but also the lock bolt is in the extended position, the door can only be opened from the inside using the pusher or knob after the lock bolt has been retracted using the associated key or via a built-in panic lock. In the case of a panic lock, the lock latch and lock bolt are moved or retracted simultaneously by pressing the pusher or knob.

In order to enable the second guide means to be moved back comfortably from the open position into the holding position, a reset device can be provided. If the reset device is not present, the second guide means is moved back by hand.

As an alternative to a blocking device, a gear device can also be provided, which establishes a drive connection between an actuating device, for example a manually operated push button or knob, and the second guide means. By actuating the actuating device, the second guide means can be moved between its stop position, in which it prevents the door from being opened, and its open position, in which it enables the door to be opened. The gear device can be a form-fitting and / or friction-locked gear with corresponding toothed and / or friction wheels. If necessary, the transmission and / or actuation device can, for example be designed to be lockable by means of a lock, so that even in this variant only certain persons can be authorized to open the door.

The guide device is preferably formed by a hollow profile rail which extends at least over part of the height of the integrated door, but preferably over the total height of the door or over the total height of the opening to be closed in the masonry. The hollow profile rail consists of a first, fixed rail leg and a second, movable rail leg, which is connected to the first rail leg via a joint or hinge. A locking bar, which extends over at least part of the height of the guide device and which forms part of the blocking device according to the invention and whose movement path can be blocked, for example by means of the lock latch and / or the lock bolt, can be fastened to the second rail leg.

The door integrated in the rolling grille or roller door can be pretensioned into its closed position by means of at least one spring. In addition, the rolling grille or rolling gate of the rolling grille or rolling gate arrangement according to the invention can consist of an upper and a lower grating or gate section, which are connected or stabilized by means of at least one hinge spring band, a so-called bomber band. The integrated door is only in the lower grille and / or gate section.

The roll-up doors provided in rolling grilles or roller doors are differentiated by wicket doors on the one hand and escape or panic doors on the other. Wicket doors are doors through which a person can pass through under normal conditions. Escape or panic doors, on the other hand, are doors that must meet the fire protection requirements. These requirements include, for example, that no dangerous stumbling edges may be present which, in the event of inattentiveness usually observed in emergencies, can lead to falls of the people passing through the doors in question with fatal consequences.

In order to meet the fire police requirements for an escape door, an interrupted first end rail can be provided at the lower end of the rolling grille or rolling gate. The part of the first end rail which extends in the region of the door opening is fastened in an articulated manner to the door segment, so that it pivots away together with the door segment when the door is opened. If the integrated door does not have to be an escape door, but a wicket door is sufficient, a continuous, second end rail can be provided at the lower end of the rolling grille or rolling gate.

2 shows a sectional view according to section AA in FIG. 1.

1 shows the inside of a rolling grille arrangement 1 "according to the embodiment. In the unrolled or unwound position shown, the rolling grille 1" closes the opening in the wall 19. With the help of the tubular shaft 18, which is rotatably mounted in the walls 19, the rolling grille 1 "including the integrated door 2" can be wound up and thereby opened.

The rolling grille 1 "consists of a plurality of grille bars 21" which extend above the integrated door 2 "continuously over the entire width of the rolling grille 1" and are interrupted by the door opening in the area below. The integrated door 2 "also consists of lattice bars 21", so that it fits optically into the overall picture of the rolling lattice 1 ". The lattice bars 21" are held together by means of a plurality of link strands 22 ", each of which is composed of a plurality of links which are articulated to one another The bars 21 "each form the articulation axes about which the individual links of the link strands rotate when the rolling grille 1" is being wound up. The vertical distance between two bars 21 "corresponds approximately to the length of one link of the link strands 22" Links of two link strands 22 "and two bars 21" limited rectangular surfaces of the rolling grille 1 "can be seen through.

Depending on the embodiment, the individual links of the link strands 22 "of the integrated door 2" correspond to or deviate from those of the remaining area of the rolling grille 1 ". The link strands 22" are composed of the links according to FIG. 2. Fig. 2 shows a link, which is provided with the lattice bars 21 "receiving bores 42 and 43 and is used for the link strands 22".

The door 2 "has a door segment 3", the left side of which is articulated to the rolling grille 1 "with the aid of an articulated hinge 23". The hinge 23 "is shown in FIG. 3. It is arranged between the link strands 24" and 25 ". The door 2" is opened in the viewing direction of FIG. 1.

The rolling grille 1 "consists of an upper grille section 59 and a lower grille section 60. A first middle rail 62 is provided at the lower end of the upper grille section 59, while the lower grille section 60 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 to each other. The second center rail 63 is thereby stabilized.

The door 2 "integrated in the rolling grille 1" is located completely in the lower grille section 60. The door 2 "has in particular the same height as the lower grille section 60. The second middle rail 63 is therefore interrupted at the location of the hinge 23" and its part in the area of the door opening swings away when the door 2 "is opened. At the lower end of the lower grating section 60 there is a first end rail 64 which is interrupted at the point of the hinge 23". Its part in the area of the door opening swings away when the door 2 "is opened. If the door 2" is to act as an escape door, the first end rail 64 forms the end of the rolling grille 1 "at the lower end. When the door 2" is open, it is in the area the door opening no stumbling edge. If a wicket door in the rolling grille 1 "is sufficient, a second closing rail 65 can be provided on the first closing rail 64, which runs continuously over the entire width of the rolling grille 1".

1 further shows two tension springs 58 which press the door 2 "into its closed position, ie out of the plane of the drawing. One of the tension springs 58 is arranged on the second central rail 63 while the other of the tension springs 58 is on the first end rail 64. One end of the tension springs 58 engages on the door 2 "while the other end is attached to the remaining part of the rolling grille 1". Both the tension springs 58 and the hinge spring band 61 can be covered if necessary ,

1 shows the guide device 50 which is supported in relation to the walls 19. It preferably extends over almost the entire height of the rolling grille 1 ″ or the opening in the wall 19. The right ends of the grille bars 21 ″ in FIG. 1 protrude into the guide device 50. The number and distribution The grating bars 21 ′ projecting into the guide device 50 over the height of the door 2 ″ can be varied from case to case.

Fig. 4 shows the section A-A marked in Fig. 1. In the right half of FIG. 4, the wall 19 can be seen, to which two angle profiles 66 and 67 are attached. A lock 54 is arranged between the two legs of the angle profiles 66 and 67 projecting from the masonry 19. The lock latch, not shown in FIG. 4, can be moved by actuating the pusher 68. The lock bolt 55 is retracted or extended by means of an associated key. A suitable deflection gear is provided in the lock 54 for converting the movement of the handle 68 or the key into a corresponding movement of the lock latch or the lock bolt 55. The lock 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 preferably actuated by means of a rotary knob. If, on the other hand, it is to function as an escape door, the lock 54 designed as a panic lock is preferably actuated by means of the handle 68.

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 their guiding 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 a substantially 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 clockwise from its holding position shown in FIG. 4, in which it holds the bars 21 "of the door segment 3" in the hollow profile rail 50, into its open position, in which it detects the movement of the bars 21 " and thus the door 2 "in the direction R _{2 is} no longer hindered, that is, it no longer has a holding effect and thus enables the door 2" to 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 ".

In order to be able to prevent the pivoting movement of the rail leg 52 into its open position, a blocking device 53 is provided. It is formed by the lock 54 together with the latch and bolt 55 and the locking bar 56, 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. 4, the extended bolt 55 is located along the movement path which moves the locking bar 56 when the rail leg 52 rotates clockwise. The extended bolt 55 thus blocks the pivoting or rotating movement of the rail leg 52 into its open position. The same applies to the extended latch of the lock 54, not shown in FIG. 4.

In the left half of FIG. 4, the lattice bars 21 "of the door 2" tapering to the right can be seen. At the tapered ends of the bars 21 "guide elements 57 are provided which are intended to guide the bars 21" in the hollow profile rail 50 with as little play as possible. The guide elements 57 can be bodies with a square, rectangular, circular-cylindrical shape or the like, which are connected in a rotationally fixed manner to the lattice bars 21 ″ Act cross-sectional shape. However, it is also conceivable to provide guide elements 57 in the form of rollers rotatably mounted on the bars 21 ″.

In the position shown in FIG. 4, 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 moving in the first direction R ₁ or inwards can open. In conjunction with the blocking device 53, the second rail leg 52 prevents the door 2 "from being able to open 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 is first drive in with the associated key. The latch of the lock 54 can then also be retracted by actuating the pusher 68. The path of movement of the locking bar 56 is then no longer blocked. Now the door 2 "can be pushed 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. There is thus nothing standing in the way of the door opening.

If the door 2 "is then to be closed again, it is first pivoted back into the rolling grille level, so that the free ends of the grille bars 21" together with guide elements 57 are again in the hollow profile rail 50. Thereupon, the rail leg 52 can finally be moved from its open position back into its holding position shown in FIG. 4. This can be done, for example, by reaching through the bars 21 "from the inside and pressing the rail leg 52" which extends at least over the height of the door 2 "into the holding position by hand. Finally, the latch of the lock 54, which was retracted before the rail leg 52 is pivoted back, can be extended again by releasing the push button 68. In addition, it can be locked again by extending the bolt 55.

In order to avoid reaching through the bars 21 "from the outside inwards and thereby activating the handle 68 from the outside, the door 2" at the height of the lock 54 has a safety device, which consists of several, between 1. The securing bars 70 arranged on the lattice bars 21 "exist, as can be seen in FIG. 1. Even if such a penetration securing device is provided, it can be reached through the lattice bars 21" above or below the securing bars 70 in order to pivot back into its holding position.

However, in order to enable the rail leg 52 to be pivoted back into its holding position more comfortably, a reset device can be provided. In the embodiment shown, this resetting device consists of a resetting boizen 71 which is displaceably mounted in the angular profile 67 and whose front end bears against the locking bar 56. When the rail leg 52 is moved into the open position, the locking bar 56 pushes the reset bolt 71 downward when viewed in FIG. inwards, out of the angle profile 67. If the rail leg 52 is to be pivoted back from its open position into the holding position, the reset bolt 71 is lifted upwards by hand, as viewed in FIG. pressed outwards, whereby he pivots the locking bar 56 and thus the rail leg 52 counterclockwise. To secure the reset bolt 71 in the angle profile 67, a securing means, not shown in FIG. 4, for example a securing ring, can be provided in the front area of its shaft. Falling out of the securing bolt 71 from the angle profile 67 is thereby excluded.

The embodiment of the invention was explained using the example of a rolling grille. In the case of a roller shutter, only the bars are replaced by roller shutter profiles or slats.
