Abstract

The device has a device parts (3.1,3.2) operating the transmission, where the device parts are exclusively located on the front surfaces of a door leaf. The device parts are protruded in the direction not over the front surfaces of the door leaf. The direction normally lies to the level of the door leaf.

Description

The invention relates to a device for avoiding jamming of the door leaves of a two-leaf hinged door to each other, wherein the one door is a unterschlagender so-called stationary leaf and the second door a sweeping so-called. Active leaf.

The invention is particularly advantageously applicable when door leaves are used with a relatively large thickness, in which in the closed state, the mutually facing end faces closely abut each other; this is typically the case with fire doors.

When the door leaves are closed, at least partial areas of these end faces are located on that side of the plane defined by the pivot axes of both door leaves, which lies behind at the opening movement of the door leaves. These areas of the end faces of the door wings move at the beginning of the opening movement of the door wings on the other door. If the gap between the end faces of the door leaves is so narrow that the door leaves open or close individually just fine, it can then jam to each other door, and thus come to block the opening movement, when trying both doors at the same time to open. The problem occurs most when the hinge axes in the opening direction are clearly in front of areas of the door leaf and when small-width and large-thickness door leaves are used.

If the inactive leaf of a double-leaf door is opened, unless otherwise opened, the active leaf of the door is also forcibly opened because it is taken along at the door rebate, so both leaves are opened at the same time. There are already several suggestions for bringing the active leaf in this opening movement, so far vorzueilen that he can not jam with the inactive leaf: According to the already published in 1985 DE 83 35 576 U1 It is proposed to attach to the rear surface of the active leaf during the opening movement an inclined plane to which a fixed to the fixed wing so-called driving pin rests with a frontally mounted thereon roller. The inclined plane is aligned so that the areas which are closer to the inactive leaf with closed wings in the opening direction of the door are further forward. This ensures that at the beginning of the opening movement of the inactive leaf movement of the driver pin on the axis of the active leaf to, the inclined plane rolls on the roller and thus the movement of the passive leaf is translated into a rapid opening movement of the active leaf. The disadvantage is that the device is optically very conspicuous when closed as well as open doors and thus very often disturbing. The great forces that occur in this type of translation can also lead to problems.

According to the DE 35 33 689 A1 a trained as a two-armed lever driver pin is used, which is pivotally mounted at the upper edge of the rearward during the opening movement of the passive leaf surface of the inactive leaf, and presses on the rear during the opening movement of the active leaf surface. Upon opening of the inactive leaf, the lever arm facing away from the active leaf collides with a pin which is fastened fixedly to the door frame, as a result of which the driver pin pivots into rapid rotation, by means of which the active leaf is pressed into a rapid opening movement. A disadvantage of this construction is again that the driving pin and its attachment visually very conspicuous and therefore often disturbing.

According to the AT 502 083 B1 Movement of the handle of the passive leaf, which is required to release it from the lock in the closed position, translated into rotational movement of a small plate, which thereby to such a page a fold on the active leaf presses, which lies behind in the opening pivoting movement of the active leaf. As a result, the active leaf is already slightly opened when only the handle of the inactive leaf is actuated without the inactive leaf itself needs to be pivoted. It is sufficient to swing the active leaf so just less than the blade thickness of the inactive leaf to avoid the jamming described above. The said plate is inconspicuously arranged on the vertical, the active leaf-facing end face of the inactive leaf and is driven by arranged in the cam part of the inactive leaf parts during movement of the handle. However, it has been shown that the plate is often damaged at this position and that it is complicated to accommodate the required translation parts in the lock part.

In the AT 010 451 U1 is the working principle of the already discussed DE 35 33 689 A1 realized once more. Trained as a two-armed lever cam pin is pivotally mounted on the upper face of the inactive leaf. With closed door leaves, the driving pin is invisible. The disadvantage is that space problems often occur with this arrangement, in particular in connection with a floating bolt rod attached to the inactive leaf. Another difficulty lies in the occurrence of very large forces that must be introduced from the driving pin at an unfavorable position in the surface normal direction in the surface of the inactive leaf.

The EP 2 085 554 A2 shows an opening sequence control for double-leaf swing doors, wherein on the upper end face of the active leaf a driver finger is mounted, which is radially displaceable on the moving leaf with respect to the pivot axis and a counterfitting on the inactive leaf from the front side in the opening movement with a kind of hooks. The device is not intended and suitable to avoid jamming the door at the beginning of the opening movement. She is to thought and suitable to open at the opening of the inactive leaf the aisle so far that the active leaf can get into a half-open waiting position in which he can be automatically held by a so-called closing sequence control against closing until the inactive leaf in his closing movement so certainly the power wing far ahead is that the inactive leaf safely reaches its closed position in front of the active leaf.

The inventor has set itself the task of creating a device by means of which the jamming of inactive leaf and active leaf of a two-leaf hinged door to each other when opening the passive leaf is reliably avoided.

The device should be visually inconspicuous and beyond particularly simple and robust form.

To solve the task is based on the principle of operation already published in 1985 DE 83 35 576 U1 recourse to the fact that, at the beginning of simultaneous opening movement, a translation part connected to the active leaf is connected to a translation part which is connected to the fixed leaf, come into contact with one another at a sliding plane and roll against each other, for which purpose the inclined plane is aligned such that the regions, which are closer to the axis of rotation of the passive leaf with closed doors in the opening direction of the door are further forward than those areas which lie further away from the axis of rotation of the passive leaf with closed doors. Slightly generalized is the DE 83 35 576 U1 the idea that the relative movement of the two door leaves is translated towards each other in a relative movement of the two door leaves, according to which the active leaf performs a fast-forwarding opening movement to the inactive leaf.

As an improvement according to the invention, it is proposed to accommodate the parts of the device according to the invention involved in the translation exclusively on the end faces of the door leaves. In a preferred embodiment, the parts involved in the translation of the device according to the invention in the direction normal to the plane of the door leaves do not protrude beyond the end faces of the door leaves.

In contrast to the view presumably in the invention for DE 83 35 576 U1 prevailed in 1983, it is by no means necessary to advance the active leaf for opening movement of the inactive leaf forcibly by at least the thickness of a door leaf (ie the width of a face of a door leaf). It is quite sufficient, the passive leaf a fraction of this width, for example, a quarter or half of this width, advance. Thus, it is quite possible, the said translation, which can be typically but not only realized by an inclined plane to accommodate the front surfaces of the door. Thus, the fitting, so the amount of parts involved in this translation device parts is extremely small, simple, unobtrusive and robust executable and attachable.

The painting Fig. 1 and Fig. 2 show a very simple embodiment of a device according to the invention. The device according to the invention consists of two plates 3.1, 3.2. The first plate 3.1 is attached to the gangway-side end region of the upper end face of the inactive leaf 1. The second plate 3.2 is attached to the bottom side end portion of the upper end face of the active leaf 2. The plates 3.1, 3.2 could also be attached to the lower end face of the door leaves. If space permits, it is advantageous to mount platelets on both the upper and lower faces. The two plates 3.1, 3.2 are in closed door leaves 1, 2 at a contact surface 4 to each other.

When the still leaf 1 is opened by the closed state of both door leaves, the active leaf is forcibly brought into an opening movement. At the beginning of these opening movements, the two door leaves undergo a relative movement towards each other. With regard to this relative movement, the contact surface 4 is arranged as an inclined plane, so that the two plates 3.1, 3.2 slide on each other at the common contact surface 4. In this way, the original triggering relative movement between the door wings, directed essentially parallel to the planes of the door leaves, causes a relative movement between the two door leaves whose direction is essentially normal to the planes of the door leaves.

The contact surface 4 is aligned with closed door leaves so that the surface areas which are closer to the axis of rotation of the passive leaf (1) lie in the opening direction of the door further forward than those areas which are further away from the axis of rotation of the passive leaf with closed doors. This ensures that when the passive leaf 1 is opened, the active leaf 2 is forced into an anticipatory opening movement. The steeper the surface 4 is aligned with respect to the plane of the door leaves, the faster is this anticipatory opening movement of the inactive leaf, but the greater the pressure forces on the surface 4 and thus on the door wings. It is in the field of expert action here to create sufficiently optimal conditions.

By the plates 3.1, 3.2 are attached directly to the end faces of the door, they can also absorb very high forces well without deforming and they can easily initiate these forces in the door without them being bent or kinked.

In the construction according to Fig. 3 the device according to the invention in turn consists of two platelets 13.1, 13.2, wherein the platelet 13.1 is attached to the upper end face of the passive leaf 1 and the platelet 13.2 on the upper end face of the active leaf 2. The two platelets 13.1, 13.2 lie with closed door wings on a contact surface 14 to each other, which is the same orientation with respect to the door and acts the same as the contact surface 4 in the example according to Fig. 1 and Fig. 2 , The plate 13.2 is guided on the moving leaf 2 with respect to the axis of rotation radially movable and that of the in Fig. 3 shown position only radially outward. It comprises, with its end portion facing the inactive leaf 1, the end region of the small plate 13.1 rigidly connected to the inactive leaf 1, in the manner of a hook, from the front side during the opening movement of the door leaves.

In addition to its function according to the invention thus has the platelet 13.2 the function of a driver finger for an opening sequence control according to the input discussed EP 2 085 554 A2 on. The decisive here function of the invention "Verklemmungsvermeidung" is so without additional effort to an opening sequence control according to the initially discussed EP 2 085 554 A2 realized as an additional function.

In the construction according to Fig. 4 the device according to the invention consists of two similar parts 23.1, 23.2, which are arranged in the gap between the mutually facing end faces of the door leaf, wherein a part 23.1 is connected to the inactive leaf 1 and the second part 23.2 with the active leaf 2. Over a contact surface 24 are the two parts 23.1, 23.2 to each other when both doors are completely or almost completely closed. With respect to relative movement of the door wings towards each other, the contact surface 24, like the contact surfaces 14 and 4 according to the previous examples, is formed as an inclined plane, which deflects the movement of the door wing toward each other into normal directed movement. In the parts 23.1 and 23.2, the inclination of the contact surface 24 relative to the end face of the door is attached to the part 23.1 or 23.2, adjustable by the parts 23.1, 23.2 each consist of two mutually pivotable parts in which the pivot angle over a Adjustment screw 23.1.1, 23.2.1, which supports the two pivotable parts against each other, adjustable. Of course, other adjustment principles, such as the metered insertion of a wedge in the acute angle between two parts held pivotally to each other, applicable. In order to minimize local forces and deformations, it is advantageous to mount a plurality of devices according to the invention consisting of pairs of parts 23.1, 23.2 in the gap between the mutually facing end faces of the door leaves. Preferably, the devices are mounted in the height of the hinges, to which the door leaves 1, 2 on the door frame are held pivotally, as the most direct support of the forces occurring on the surrounding wall.

Fig. 5 and Fig. 6 show a device according to the invention, in which the translation of the movement of the door wings toward each other in a normal directed movement not as in the previous examples by means of the principle of the inclined plane, but by means of a two-armed, pivoting lever. The inventive device consists of a part 43.1, which is rigidly connected to the inactive leaf 1, and a two-armed lever 43.2, which is pivotally mounted on the moving leaf 2, wherein the pivot axis is parallel to the axes of rotation of the door and wherein the two arms of the lever 43.2 stand approximately normal to each other. The part 43.1 connected to the active leaf 1 bears against both arms of the pivotable lever 43.2. Movement of the passive leaf 1 on the active leaf 2, causes the part 43.1 presses on the approximately normal to the planes of the door aligned lever arm 43.2.1 of the lever 43.2 and thus rotates the lever 43.2. The second lever arm 43.2.2, which is aligned approximately parallel to the planes of the door leaves, is thus moved approximately normal to the planes of the door leaves. By the second lever arm 43.2.2 is supported on the part connected to the passive leaf 1 43.1, get the door (more precisely, the adjacent areas of the two leaves) in the present invention desired and required relative movement in about the plane of the door normal direction lying.

The parts 43.1, 43.2 are typically arranged on the upper and / or lower end faces of the door leaves. But they can also be arranged in recesses on the mutually facing end faces of the door leaf.

Fig. 7 shows a device according to the invention, in which the most important element is a one-armed lever 53.2, which is held pivotally mounted on the moving leaf 2, wherein its Pivoting axis is parallel to the pivot axes of the door leaf and wherein it is aligned with closed doors almost parallel to the door leaf level but not quite parallel. The free end of the lever is supported on a stop part 53.1 arranged on the inactive leaf 1. When the two door leaves are moved towards each other, the lever 53.2 is pivoted, while it presses the mutually facing end faces of the two door leaves 1, 2 in a relative movement, which is normal to the plane of the door normal. Of course, a device according to the invention according to the principle shown in Fig. 8 can also be attached to the upper and lower end faces of the door leaf.

For all the outlined principles of operation, it is advantageous for static reasons, to install the corresponding devices in several places along the height of the door leaves.

Especially regarding the construction according to the FIGS. 5 to 7 It should be noted that it is permissible, with respect to the installation of the device parts according to the invention to interchange still leaf 1 and leaf 2 with respect to the illustrated embodiment. For example, the pivotable levers 43.2, 53.2 need not necessarily be attached to the active leaf 2; they can just as well be attached to the inactive leaf 1 and from there act on the active leaf 2.

According to the principle underlying the invention, the small movement which the door wings at the beginning of the common opening movement to perform each other translated into a greater relative movement by which the facing end faces of the door wings are moved normal to the planes of the door past each other. It comes with respect to the pivot axes of the door to large radial compressive forces in the door wings. These pressure forces drive the translation according to the invention. But there are also the doors and the at the Translation involved device parts designed to be stable accordingly! In the context of expert action, this stable interpretation is quite workable.
