Description

The present invention relates to a closing sequence controller for a two-leaf door construction with a stationary leaf and a moving leaf, wherein the inactive leaf and the active leaf are each connected to the axis of a bottom door closer, with a housing in which a rotatable on the axis of the bottom door closer cam plate is rotatably mounted and a triggering element cooperating with one end with the cam disc and connectable to the other end with a traction means is mounted displaceably perpendicular to the axis of the bottom door closer.

The invention further provides a, in particular for fire protection purposes trained, two-leaf door construction with a fixed leaf and a moving leaf, the inactive leaf and the active leaf are each connected to the axis of a floor door closer, the door construction is provided with at least one closing sequence controller according to the invention.

In the prior art, door structures, in particular fire doors for installation in fixed fire protection partitions in numerous embodiments and embodiments are known. For example, the DE 298 19 678 U1 a fire protection partition made of glass, in which a single swing door is integrated. The door leaf of the revolving door consists of a fire-resistant window enclosed in a wooden frame, which is hinged on a door frame by means of hinges attached to the wooden frame. While such door designs are suitable for passage of people, larger items or vehicles can not be moved through because of the limited doorway cut-outs of these doors.

If required for larger closable openings, for example, in fire-resistant glazing, therefore, among other double-wing fire doors with a fixed wing and a leaf, but also two-leaf fire doors with a designed as a rotary wing and a wing designed as sliding leaf used. In such, door structures designed in particular for fire protection purposes, the correct sequence must be observed when closing the door constructions, with the fixed leaf and then the active leaf being normally closed first, in particular in the case of fire.

In order to realize a safe and automatic closing, sometimes even opening, a door construction, so-called door closers are known in the art, for example, when closing by means of acting in the closing direction, preferably automatic drive means both the movement of wings of a door structure in the Frame as well as the falling of the latch of a door lock in a strike plate allow. The drive means may be a purely mechanical, electrical, hydraulic and / or pneumatic drive means.

In particular designed for fire protection door designs ensure door closers controlled closing the wings of a door construction. For this purpose, the door closers generally work together with so-called closing sequence controllers, which ensure the correct sequence when closing double-leaf door constructions.

In so-called overhead door closers or overhead door closers, each wing of the door construction is provided with a door closer. The door closer of a wing can be placed on the wing or integrated in this. The door closer of a wing is thereby connected to a lever arm or a linkage with a arranged on the door frame of the door structure or embedded in this slide rail. The lever arm engages in the slide rail in a slide, which is connected to the lever arm. The closing sequence control between the two slides and wings of the door construction via a push member or a push rod, which triggers a locking device. When the sash moves, the lever arm of the sash takes the slider in the slide. The displacement or displacement of the sliding carriage in the slide is relatively large depending on the width of the respective wing and accordingly requires a relatively large length of the slide rail. Often, the optical design is perceived as disadvantageous in such overhead door closers, especially since the door closers, Lever arms or linkage, slide rails and glides are visually striking and can affect the design of a door construction.

Also in order to avoid such visual impairments, in addition to upper door closers in the prior art also known as floor door closers, which are embedded in the floor, usually using so-called cement boxes. The bottom door closers each provide an axis of rotation for the wing of a door structure, which is automatically or automatically pivotable or rotatable by means of a mechanical, electrical, hydraulic and / or pneumatic drive means. The axis of a floor door closer is connected to the wing of a door structure, either directly, by the wing is placed on the axis of rotation of the floor spring, or indirectly via a lever which is mounted on the axis of rotation of the bottom door closer and to which the wing of the door construction is attached ,

For closing sequence control is used in such a floor door closers cooperating with the axis of the bottom door closer closing sequence controller, which is placed on the bottom door closer, so that it is also visually inconspicuous and the design of a door construction little or no disturbing buildable.

Such a closing sequence controller for a bottom door closer has a housing in which a rotatable on the axis of the bottom door closer cam is rotatably mounted and in which a cooperating with one end of the cam and connectable to the other end with a traction element triggering element perpendicular to the axis of the bottom door closer is slidably mounted. About the traction means, such as a so-called Bowden cable, which is also not visible visually, for example, arranged in the floor area running, the interaction of the trigger element with the cam is adjustable. In a two-leaf door construction, in which the triggering elements of the closing sequence controller of the two bottom door closers of the wings are each connected to one end of a shared traction means, on the adjustability of the interaction of the triggering elements with the cams a closing sequence control can be accomplished, in the first the inactive leaf is closed and then the active leaf is closed.

A disadvantage of the previously known floor door closers and the closure sequence controllers used in connection therewith is that the axes of rotation of the floor spring have a certain play of movement, which results in that the stops and / or closing angles of the wings, in particular in the closed state, vary and are not defined. Thus, the wings of a door construction, for example, in the upper area already strike the frame of the door construction, while they are overstretched in the bottom area, so that a safe and clean closing is not given. This is unacceptable, especially for door structures designed for fire protection purposes, as this impairs their function in the event of fire.

The adaptation and / or correction of the stops and / or closing angle of the wings of a two-leaf door construction has hitherto been possible only to a limited extent, not sufficiently accurate and, moreover, extremely expensive. For example, first axes must be separated and twisted welded together and then angle corrections are made when welding the hinges of the wings of a door construction. Often it is also necessary to adjust, to change the position of the floor spring in the floor, for example by turning the measures provided for receiving the floor spring closures cement boxes or the like. All these measures find their limits in the tolerances of the axes of rotation of the floor spring.

Against this background, the object of the present invention is to improve and simplify the adjustability of the stops or closing angles of floor door closers.

The technical solution is the present invention, a closing sequence controller for a trained, especially for fire protection purposes, two-leaf door construction with a fixed leaf and a moving leaf, the inactive leaf and the active leaf are each connected to the axis of a floor spring, with a housing in which one on the axis of the Anordbare cam plate is rotatably mounted and a cooperating with one end with the cam and connectable to the other end with a traction means trigger element is mounted perpendicular to the axis of the bottom door closer, proposed, which is characterized in that the displacement region of the trigger element by means of a through the Housing guided screw from outside the housing is adjustable.

The present invention makes use of the knowledge gained in practice that an adjustability of the stops and the closing angle of a bottom door closer is made possible by influencing the invention on the displacement region of the triggering element of a closing sequence controller.

A preferred embodiment of the invention provides that by adjusting the interaction of the trigger element with the cam, the stops and / or the closing angle of the stationary leaf or the active leaf are adjustable.

In a further embodiment of the invention it is provided that the screw is guided by a thread having an opening or recess of the housing.

A further advantageous embodiment of the invention provides that the screw is guided by a threaded sleeve having an internal thread in the housing of the closing sequence controller, preferably in the vicinity of the contact region of the triggering element. When using such a threaded sleeve in the housing of the closing sequence controller can be advantageously omitted if necessary on the thread in the opening or recess of the housing through which the screw is guided.

Advantageously, the screw is a threaded pin. Preferably, the screw head of the threaded pin has a hexagon socket according to DIN or ISO. The use of a threaded pin as a screw allows the screw itself is completely guided in the housing or the housing wall. Advantageously, the screw does not protrude from the housing of the closing sequence controller and is nevertheless accessible from outside the housing for adjustment.

A further embodiment of the invention provides that the housing of the closing sequence controller has a substantially trough-like base part, which is preferably closable with a cover plate. In a further embodiment of the invention, the cover plate is preferably likewise trough-shaped.

Fig. 1 and Fig. 2 show a trained especially for fire protection door construction 1 with a passive leaf 2 and a moving leaf 3, which are arranged directly next to each other. The inactive leaf 2 and / or the active leaf 3 of the door construction 1 can be designed as fire-resistant glass doors. The door construction 1 can be used with or without frame, in the recess of a wall or as part of a fire-resistant glazing (in Fig. 1 and Fig. 2 denoted by reference numerals 10 and 11).

For the inactive leaf 2 and the active leaf 3 of the door construction 1, a bottom door closer 4 or 5 is respectively provided, which provides an axis 6 or 7 for the inactive leaf 2 and the active leaf 3, respectively. The bottom door closers 4 and 5 allow by means of a mechanical, electrical, hydraulic and / or pneumatic drive means automatically or automatically pivoting or rotating the inactive leaf 2 or active leaf 3 about the axis 6 and 7 (in Fig. 2 represented by the double arrows marked with the reference symbol SD). The axes 6 and 7 of the bottom door closer 4 and 5 are connected to the inactive leaf 2 or leaf 3 of the door structure 1, either directly by the respective wing 2 and 2 on the axis 6 and 7 of the respective floor spring 4 or 5, or indirectly via a lever 19 or 20, which is placed on the axis 6 or 7 of the bottom door closer 4 and 5 and to which the inactive leaf 2 or the active leaf 3 of the door structure 1 is attached. The bottom door closers 4 and 5 are embedded in the floor or floor B, in particular using so-called cement boxes, such that only the axes 6 and 7 of the bottom door closer 4 and 5 protrude from the bottom B.

For closing sequence control is at the bottom door closers 4 and 5 respectively provided with the axis 6 and 7 of the bottom door closer 4 and 5 cooperating closing sequence controller 8 and 9, which is placed on the bottom door closer 4 and 5, so that this also visually inconspicuous with the bottom B completes. The closing sequence controllers 8 and 9 provide in particular for the correct sequence when closing the inactive leaf 2 and the active leaf 3 of the door structure 1, wherein advantageously the inactive leaf 2 and then the active leaf 3 are closed.

Fig. 3 shows a closing sequence controller 8 and 9, with a housing 14 which is formed substantially as a trough-like base part. The base part of the housing 14 can be closed with a cover plate, not shown here, or with a likewise substantially trough-like cover part.

In the housing 14 of the closing sequence controller 8 and 9, a cam 15 is rotatably mounted (in Fig. 3 shown on the right). The cam 15 is on the axis 6 or 7 of the bottom door closer 4 or 5 can be arranged, including the housing 14 and the cam 15 has an opening for the passage of the axis 6 and 7 of the bottom door closer 4 and 5 respectively.

In the housing 14 of the closing sequence controller 8 and 9, a trigger element 16 is also slidably mounted. The displacement V of the trigger element 16 is perpendicular to the direction of extension of the axis 6 and 7 of the bottom door closer 4 and 5 possible. The trigger element 16 has a cooperating with the cam 15 actuating arm 16a, which is arranged on the cam 15 facing the end of the trigger element 16 on the trigger element 16 or formed directly from or with this in one piece. The other, the cam 15 remote from the end of the trigger element 16 is connected via a guided through the housing 14 Zugmittelanschluss 17 with a traction means 12 and 13, preferably a Bowden cable, connectable. In this case, the traction means 12 and 13 are connected to each other or a single traction means is used, which connects the two closing sequence controller 8 and 9 of the door structure 1, so that in the context of the closing sequence control first of the inactive leaf 2 and then the active leaf 3 is closed.

As Fig. 3 shows, the displacement region of the trigger element 16 is adjustable by means of a guided through the housing 14 screw 18 from outside the housing 4 ago. For this purpose, the screw 18 protrudes into the displacement region of the triggering element 16. The screw 18 is designed as a threaded pin 18 and has at the screw head end 22 a hexagon socket as a screw head. The screw head of the screw 18 is accessible from outside the housing forth. The screw head end 22 opposite end 21 of the screw 18, hereinafter also referred to as the contact end 21 is engageable with a Zugmittelanschluss 17 of the trigger element 16 opposite end of the trigger element 16 in contact. By adjusting the screw 18, the displacement range of the trigger element 16 is then adjustable. The screw 18 is guided in a plane spanned by the trigger element 16 plane extending through the housing 14 and occupies an angle α of about 10 ° to the displacement direction V of the trigger element 16 a. The screw 18 is guided substantially tangentially on the cam 15 and / or on the axis 6 and 7 of the bottom door closer 4 and 5, respectively. By adjusting the displacement range of the trigger element 16, the interaction of the trigger element 16 with the cam 15 is adjustable in that the abutment of the actuating arm 16 of the trigger element 16 on the cam 15 is variable by the displacement range of the trigger element 16. By adjusting the interaction of the trigger element 16 and its actuating arm 16a with the cam 15 then the stops and / or the closing angle of the inactive leaf 2 and / or the active leaf 3 of the door structure 1 are adjustable.

This in Fig. 4 illustrated embodiment of a closing sequence controller 8, 9 differs from that in Fig. 3 illustrated by the provision of a housing 14 arranged in the threaded sleeve 23. The guided through an opening in the edge region of the housing 14 screw 18 is guided by the housing 14 in the vicinity of the contact region of the trigger element 16 arranged, having an internal thread threaded sleeve 23. The opening in the housing 14 through which the screw 18 is guided, it must have no internal thread. The adjustability of the interaction of the trigger element 16 and its actuating arm 16a with the cam 15 and thus the adjustability of the stops and / or closing angle of the inactive leaf 2 and / or the active leaf 3 of the door structure 1 in the embodiment according to Fig. 4 according to the embodiment according to Fig. 3 given.
