Description

Gate with a gate leaf that can be moved approximately vertically or overhead, in particular overhead sectional door, roller door, lifting gate or the like, with a vertical running frame with frame, which in the inner edge area of the is fixed with the door leaf to be closed, with a Guide rail device in which on the inside of the door leaf protruding rollers can be moved in the longitudinal direction of the rails engage, and with one on at least one side of the door leaf this specified catch pawl device, the catch pawl in about Movement plane perpendicular to the plane of the door leaf is extendable if the door leaf holding ropes or the like. By failure of the Holding function become slack, which causes the catch in one of the engagement training intervenes in the one that forms a catch rail, the area of the respective catch pawl device on the Frame edge to be determined inside the edge opening of the door opening at least a larger part of the longitudinal extension in succession are formed; the assigned frame can be attached to the side rail Guide rail device can be set.

A gate of this type, on the door leaf on both sides of a catch pawl device each with an approximately perpendicular plane of movement to the door leaf level is equipped for the catch, can the embodiment European Patent 0172351, which discloses the features of the preambles of independent claims 1 and 7. The Catch pawl works there with a catch rail, which in comparison to further state of the art relatively close to the boundary the gate opening to be closed is arranged. These with openings for the engagement of the catch pawl provided on a multi-part Frame formation determined on which also the approximately vertical area of the guide rails for those protruding from the inner wall of the door leaf arranged rollers of the door leaf guide are held. The bracket the safety rail is hit in only one of its edge areas in such a way that this with one of the inner wall border with the Leg of the frame device protruding from the door leaf to be closed is set, making a relatively large lever arm for to be introduced into the boundary wall of the door leaf opening in the event of a catch abrupt catch forces are given.

It is also known - DE 37 10 237 A1 - in a plane parallel to Door leaf level movable catch pawl arranged on the side of the door leaf Catch catch device for engaging in openings let that in one of the inner wall edges of the to be closed Leg opening projecting leg formed an angular frame is, whose other leg on the inner wall edge with the Door leaf to be locked door opening is set. The one from this inner wall area protruding legs with the openings for the Catch pawl also serves to hold the vertical area of a Guide rail device. Here, too, a relatively large one occurs Lever arm for the forces occurring in the catching case, which are in the frame the edge of the gate opening is inserted and picked up by them have to. In addition, in cases of pawl movement, approximately parallel to the door leaf level, the risk of tilting the door leaf in the Catch trap relatively large, taking into account that only one the ropes attached to both sides of the door leaf or the like in the event of a fault becomes slack. Such tilting prevents the door leaf from moving a forklift or the like underneath the lower edge of the defective one To free the gate from its more or less closed position and thus the Release the gate opening.

Finally, it is known - FR-A-2 123 953 - as vertically running frame bars Square hollow profiles to use, with one side on the Apply to the inner wall edge area of the door leaf opening and parallel in this side extending opposite side engagement openings for one Have safety rocker arm which is arranged in the guide rail device and with its catch latch nose openings in the inner wall engages through facing edge region, which with the engagement openings of the Frame hollow profile are designed correspondingly, this edge area directly to the side of the frame profile which has the engagement openings adjacent. This is between the fastening zone of the frame profile on Inner wall edge area of the gate opening and the engagement openings kept relatively large distance in terms of the initiation of Catch forces is effective as a lever arm.

The invention has for its object to provide a gate of the type mentioned to create a catch pawl device, through which in the catch case transmitted forces in a particularly favorable manner in the opening wall can be derived, with little constructive effort and avoidance risk of canting by the catch pawl device.

Starting from a gate with the characteristics mentioned at the beginning, this is Object achieved in a first embodiment by the features of claim 1.

According to the invention, the engagement training for the in their catch position Advance catch pawl of the catch pawl device directly on the frame the area adjacent to the masonry of the gate opening is initiated, and in the form of expressions facing the catch and one Have a border for receiving the extended catch. So that will on the one hand ensures that the catching forces exerted via the catch pawl be introduced directly into the frame, in an area that itself on the masonry surrounding the gate opening and the catching forces about the boundaries of the expression concerned in a very slight lever arm from the fixing to the masonry. Doing so leave the idea that the catch must go into an opening in a catch rail intervene in such a way that it penetrates this opening when caught. The expressions provided according to the invention from the Frame material in the direction of the catch has the special one Advantage that the expressions on the inner wall edge of the masonry surrounding the gate opening Frame part can lie flat and none in the direction of the masonry recesses to accommodate the Catch pawl requires what is particularly important when installing the gate Location has an advantageous effect.

In a preferred embodiment, the frame spar has two approximately at right angles mutually extending legs, one of which forms the catch rail, at the other, protruding from the inner wall edge of the gate opening Leg the guide rail device is attached. Furthermore can on the inner rail border forming the safety rail the frame spar part fastened to the door opening - in particular legs the angular frame - on the edge area facing the door leaf a turn with a receiving groove for one on the facing Side area of the door leaf attacking seal may be provided.

The expressions intended for the attack of the pawl from the frame area adjacent to the wall or from its flat area Frame material becomes approximately perpendicular to the frame longitudinal direction guided cutting of the frame material and a longitudinal frame direction Looking down pocket-shaped bulge in the direction turned away from the inner wall edge of the door opening, at the the frame spar is to be attached. In principle it would be possible Expressions of the type according to the invention as hump-like projections to design, but this sets a correspondingly deep-drawable Frame material ahead and also requires a stop edge formation for the catch pawl, which prevents it from sliding off. In preferred Execution is therefore the one provided in the context of the expressions Cutting through the frame material and thus a clear edge formation intended. Which are below the separating edge or stop edge of the Expression-shaped pocket-shaped bulge allows the Catch pawl with regard to its stop surface in the catching position to the frame spar and let it run downwards at an angle, so that the catch pawl in the catch position so far into the bulge engages and thus a clinging of the door leaf to the frame causes.

The bulge and in particular its upward facing as a stop for the catch pawl can be shaped differently, for example with regard to the course of the stop edge in the form of a circular section, but preferably in the direction of a trapezoid, so that a certain mobility of the door leaf in its plane and perpendicular to Direction of movement is possible without affecting the fishing situation. The transitions between the shorter of the two can be parallel Trapezoidal sides and the trapezoidal legs be rounded.

To over the stop on the upper edge of each in the trap affected expression on the catch pawl initiated well To be able to derive the frame, the bulge is designed such that it preferably with the not fully booked neighboring frame profile in Door leaf level and perpendicular to the longitudinal direction of the vertical frame profile seen in the central plane of the bulges an approximately triangular Includes area.

Starting from a gate of the type mentioned at the outset, the object is achieved in a second alternative by the features of claim 7.

Accordingly, the frame spar has at least one leg, which in its central region is U-shaped, the two legs this U-shaped bulge essentially parallel to the surface normal of the door leaf run so that the connecting the two legs Bars, which has the openings for the engagement of the catch pawl in is arranged substantially parallel to the surface of the door leaf. A Such frame spar is particularly inexpensive with a low design Effort can be produced, in particular risk of canting can be avoided by the catch pawls. The production The frame spar can namely, for example, with a corresponding Tool done in one machining step, using the frame spar pressed simultaneously into the appropriate shape and punched out the openings become.

According to a further feature of this alternative embodiment, that the openings are rectangular. The rectangular one Formation of the openings has the particular advantage that at maximum Opening the profile ensures the greatest possible stability of the frame spar is achieved.

It is also provided that the openings are evenly spaced from one another are arranged in the profile of the frame spar. This will be the advantage achieved that interception of the gate in the event of a fault in a variety from positions so that the remaining movement of the door leaf in Malfunction trap is as low as possible, for example, to prevent injuries from to avoid people standing underneath. In addition, the Catch latch devices due to the relatively small movement of the door leaf absorb only a small amount of kinetic energy in the event of a fault.

In a preferred embodiment, the frame spar has two approximately at right angles mutually extending legs, one of which forms the catch loop and at their other, from the inner wall edge of the gate opening protruding leg the guide rail device is attached. Of further can on the inner rail border forming the catch rail the door frame part attached to the door opening - in particular Leg of the angular frame - on the side facing the door leaf Edge area a bend with a receiving groove for one on the facing Side area of the door leaf attacking seal provided be.

Figures 1 and 2 each show one of the two approximately vertically extending Frame bars 2 of an otherwise not shown, on the Frame on the inner wall area of the door opening. Figure 1 shows a view in the plane of the wall opening on one arranged in front of this Frame spar 2 with regionally indicated guide rail device 3, while FIG. 2 shows a 90 ° counterclockwise direction panned side view of the from the inner wall the door frame facing away from the gate opening. Figure 1 shows thus an outside side view of the inner wall of the assembled frame spar 5 and Figure 2 a inside view of the leg 4 of the angular frame spar 2, with in the manner described in more detail below as a catch rail Expressions 10 is provided.

The door leaf 1 - in Figure 5 with respect to its lateral edge area opposite the one of the two vertical side rails 2 shown - bears an overall protruding from its lateral edge area designated 8 catch pawl and is in a manner not shown provided with holders for rollers on its inner surface on the edge, in a guide rail device 3 in the direction of the door leaf movement inserted between the open and closed positions are, of the - Figure 5 - only in cross section the approximately vertical Area is indicated.

Each frame spar 2 is generally designed as an angle profile, which has a first, a leg 4 forming a rail and another leg 5, on the edge region remote from the leg 4 of the vertical course of the guide rail device 3 is fixed. Of the Leg 4 serves to fasten the frame spar to the inner wall edge the gate opening, i.e. it lies against this wall. The other Leg is therefore approximately perpendicular to this having the gate opening Wall from.

The catch pawl device 8 has a catch pawl 9, which is the leg 4, i.e. whose from the contact surface on the inner wall the side facing away from the gate opening and in not shown Way, i.e. using any technique, in the trap, i.e. if you become slack one, not shown, attacking the underside of the door leaf Rope or the like. To move to the leg 4.

The leg 4 of the frame spar 2 has successive ones in the longitudinal direction of the bar Expressions 10, which face the pawl. This Expressions are obtained by cutting through the frame material in the region of the leg 4 approximately perpendicular to the longitudinal direction of the bar and by pocket-shaped bulges 12, each of which adjusts to the Connect the cut to the bottom. Thus one arises from the flat leg 4 of the side rail from the inner wall edge of the Edge 11 facing away from the gate opening as the upper end of the pocket-shaped bulge 12, which border 11 through the severing of the leg material is formed and defined. At this boundary strikes the catch 9 in a manner not shown, when it is moved to the catch position. Which expression 10 or Boundary 11 serves as a stop for the catch 9 depends on the door leaf position when the fall is triggered.

As can be seen in FIG. 5, the border 11 does not show together with the deformed leg side of the frame spar 2 in the shape of a trapezoid, the shorter trapezoidal side 13 located in the area of the boundary 11 merges into the trapezoid legs. It is created in this way an approximately horizontal border that covers a certain area the width of the leg 4 of the frame spar 2 overlaps, so that also lateral movements of the door leaf over its roles within the guide device 3 a secure engagement of the catch pawl 9 for do not interfere with the catch.

As can be seen from FIG. 4, a section along the line IV-IV in FIG. 3 shows a triangular one in the central width region of the expressions 10 Area 14 through the pocket-shaped bulge 12 and not deformed leg material is stretched. If you make sure that the Catch pawl with a stop edge pointing slightly downwards towards the frame is provided, there is a force component of the catch pawl device 8 and thus the door leaf 1 towards the leg 4 of the frame, so that sliding and / or an unpleasant burden on the guide device is avoided.

As can be seen in particular in FIG. 3, that which is successive in the longitudinal direction of the bar is Row of bulges 10 interrupted at the points in particular by cutting out an expression which the leg 4 of the frame spar 2 by means of, not shown, corresponding Openings 16 in the leg 4 of the frame spar 2 penetrating Screw bolts on the inner wall edge of the door opening is set.

The exemplary embodiment points to the side edge region of the leg 4 of the frame spar 2, the leg 5 of which is turned away, another one Turn 6 on, at the free end of a receiving groove 7 for fixing a seal, not shown, is formed, which in the closed state attacks on the outer surface of the door leaf 1. The catch pawl device 8 is arranged on the side of the door leaf 1 such that it at least in some areas between the legs 4 and 5 of the frame spar spanned triangular space 15 engages. This results in a Protected and space-saving arrangement for the catch pawl device.

FIGS. 6 to 11 show a second embodiment of a gate shown, the same components with the same reference numerals of the figures 1 to 5 are designated.

In the gate according to Figures 6 to 11, the leg 4 of the Zargenholms 2 a U-shaped protruding towards the door leaf 1 trained profile 31. This profile 31 therefore consists of two Legs 32 running parallel to the surface normal of the door leaf 1 and 33 and a web 34 connecting the legs 32 and 33. The Web 34 accordingly runs parallel to the surface of the door leaf 1 or in other words, perpendicular to the surface normal of the door leaf 1.

In the web 34, the openings 30 are arranged, which are rectangular are formed, the corners of the openings 30 being rounded.

The openings 30 are substantially evenly spaced arranged to each other in the profile 31 of the frame spar 2, their uniform spacing is interrupted only in the areas which bores 16 are present, in which corresponding Fasteners, such as screws are inserted, the Attach the frame spar 2 to the building 20. In the field of Bores 16 provide that the profile 31 is interrupted in such a way that the leg 4 of the frame spar 2 with its entire surface in Area of the bore 16 abuts the masonry of the building 20.

As FIG. 6 in particular shows, the leg 4 has in its Side edge area, namely in the area that the leg 5 of the Zargenholms facing away, a turn 6, at its free end a receiving groove 7 is designed for fixing a seal 25, which rests on the outer surface of the door leaf 1 in the closed state. The Catch pawl device 8 is arranged on the side of the door leaf 1 in such a way that they are at least partially in between the legs 4 and 5 of the frame spar 2 engages triangular space. This gives a protected and space-saving arrangement for the Safety catch device 8.
