Description

The invention relates to a device for opening sequence control of two-leaf swing doors, wherein the one wing is a unterschlagender so-called passive leaf and the second wing is 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 wings is so narrow that the wings can be individually opened or closed just fine, then it can come to jam wings together, and thus to block the opening movement, when trying both wings at the same time to open. The problem occurs most with small width, large thickness door leaves.

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 wings are opened at the same time. There are several suggestions for causing the active leaf during this opening movement, as far as vorzueilen that he can not jam with the passive leaf:

According to the DE GM 83 35 576 It is proposed to attach an inclined plane on the inactive leaf, against which a pin attached to the inactive leaf rests with a roller mounted on the end face. The geometry is designed so that the occurring during the opening movement of the inactive leaf movement of the pin is translated to the active leaf to a faster opening movement of the active leaf. The advantage of a simple mechanism are contrasted by disadvantages that the device visually very conspicuous and thus very annoying, and that the angle of the inclined plane for each door width and door thickness must be adjusted.

According to the DE 35 33 689 a driver pin is used, which is movably mounted on the inactive leaf via a control unit, and presses on the rear surface of the active leaf during the opening movement. By the action of the control unit, the driving pin presses the active leaf during opening of the passive leaf in a faster opening movement. A disadvantage of this solution, which is in itself comfortable, is that the driving pin and the control unit are visually very conspicuous and therefore often disturbing.

The DE 198 55 402 C1 , which discloses all features of the preamble of claim 1, shows a device for opening sequence control of double-leaf swing doors. A tab, which is attached to the upper end face of the passive leaf, protrudes to the moving leaf and translates the opening movement of the passive leaf in a faster opening movement of the active leaf. This is intended and achieved that when opening the inactive leaf of the active leaf forcibly opened so far that the later become active closing sequence control can work. Since the device translates only the actual movement of the passive leaf, it can cause in the very first part of the opening movement of the passive leaf too little advantage of the active leaf to prevent tilting of the two wings together with very strong wings.

The BE 454 811 A shows a tab on a door, which is in gear connection with the door handle and serves to prevent the unwanted slamming of the door leaf. For this purpose, the tab can protrude into the area in front of the front side of the wing, in which the door frame or possibly a second wing protrudes when the door leaf is closed. Pressing the door handle moves the tab away from this area so that the door can be closed.

The DE 340 299 C also shows a tab on a door, which serves to prevent the unwanted slamming of the door leaf. The tab is arranged on the front side of the door leaf and rotatably mounted in the lock case in a plane lying normal to the pivot plane of the door leaf It does not like the tab corresponding to the BE 454 811 A with the door handle in gear connection. When the door leaf is already open, it can be swiveled back and forth between a protruding (effective) and an assisted (inactive) position, regardless of the position of the door handle.

The inventor has set himself the task to provide for a two-wing swing door an opening sequence control, which ensures that the active leaf in its opening movement of the inactive leaf at the beginning of its opening movement so far ahead, that jamming between the facing faces of solid leaf and active leaf is avoided. The device should be as inconspicuous as possible when the door is closed, and when the door is fully open, i. get along without parts, which protrude freely in the room. So that the device can function sufficiently safely even in the case of fire expected conditions, it should be feasible without electrical, hydraulic or pneumatic functional parts. This task is to be solved as inexpensively.

To solve the problem is provided on the, the active leaf edge facing the passive leaf to install a device according to claim 1 with a movable tab, which tab is moved via a gear when a door handle for unlocking the passive leaf is rotated from the closed position. In this movement, an edge region of the tab lies in the Area of the side of the wing facing edge of the active leaf at this, and presses the active leaf in an opening movement.

The invention will be more apparent from the drawings which show an embodiment principle:

Fig. 1:

shows in a partial sectional view from above an embodiment of the double-winged hinged door according to the invention in the position in which it is pressed handle of the passive leaf for unlocking.

Fig. 2:

shows a oblique view of the lock box which in the passive leaf of the door according to Fig. 1 installed and equipped with an embodiment of the tab according to the invention. One of the two possible end positions of the tab is symbolized by dashed lines.

As in Fig. 1 Recognizable, the inactive leaf 2 is equipped with a folding leaf 2.1 directed toward the active leaf 1, on which, when the door is properly closed, the inactive leaf bears against the edge region 1.11, which is also formed as a fold, on its front surface during the closing movement.

At the transition wing-side end face 2.2 of the passive leaf 2, its thickness is in the much smaller thickness of the fold 2.1 on. When the wings are closed, the mutually facing end faces 1.1 and 2.2 of the active leaf and the stationary leaf are very close to each other in parallel. The pivot axes 1.3, 2.3 of the wings are on that side of the door, on which the wings pivot during the opening movement. Thus, the faces of the individual wings in the first part of the opening movement also move slightly towards the other wing.

At the the active leaf-facing end face 2.2 of the passive leaf designed as a flat elongated plate tab 4 is arranged. In the resting state, this tab 4 lies with its surface parallel to the end face 2.2 at least approximately on this.

The tab 4 is connected via a transmission connection with the pivot shaft 3.1 of the door handles 3 of the passive leaf 2 in engagement. When pressed to unlock the passive leaf from the closed position on a door handle 3, the pivot shaft is 3.1 in the in Fig. 2 Turned with an arrow symbolized rotation. The tab 4 is about the axis located near one end 4.1 from the in Fig. 2 pivoted position shown by solid lines in the position shown by dashed lines. That is, their longitudinal direction is rotated from the direction parallel to the adjacent edge of the inactive blade 2 longitudinal direction substantially in the direction which is normal to the plane of the inactive leaf in the direction of opening movement of the wing. If the active leaf 1 has not already been brought into the open position, the edge region of the flap 4 lying away from the axis 4.1 lies In this case, at the near, in the opening movement rear edge region 1.1 of the active leaf 1 and exerts at this point of contact a compressive force on the active leaf 1, by which this is rotated about its hinge axis in an inactive leaf 2 opening movement.

The force exerted by the tab 4 on the active leaf 1 has the greatest possible normal distance to the pivot axis of the active leaf. As a result, this force does not need to be large to move the active leaf.

The tab 4 and acting between its axis of rotation 4.1 and the handle shaft 3.1 of the passive leaf 2 gear, are - as in Fig. 2 sketched - best already housed in the lock case 5 of the passive leaf. The translation of the rotational movement of the handle shaft 3.1 in the rotational movement of the not far away tab 4 to the differently oriented axis 4.1, can be easily realized by interlocking solids, such as bevel gears.

When the wings are closed and the handles 3 are not depressed, the tab 4 is hidden in the gap between the active leaf and the fixed leaf. When the wings are open and the handles 3 are not depressed, they are inconspicuously attached to the end face 2.2 of the passive leaf 2.

It is advantageous to align the substantially horizontal pivot axis 4.1 of the tab 4 is not exactly parallel to the plane of the inactive leaf 2, but so that it is parallel to the plane of the active leaf 1, if this is a small piece of open, and the inactive leaf 2 in closed position. This ensures that it also abuts well on the edge region 1.1 of the active leaf, if its thickness is very small, and it is located close to the end face 2.2 of the passive leaf 2.

The contact surfaces between the tab 4 and the active leaf 1 should be equipped accordingly, that there is no disturbing friction and no damage. For example, sliding coatings can be arranged, or the tab 4 can be equipped with a roller.

Thus, due to the strength of the tab 4, the gap between the facing end faces of the door must not be larger than otherwise required, may be attached to the end face 2.2 of the inactive leaf 2 and / or on the end face 1.1 of the active leaf 1, a shallow depression, in which the flap 4 comes to rest with the wings closed.

With the described equipment, it is also possible to provide such a two-leaf doors, which is a high aesthetic claim, with an opening sequence control. As a result, security doors against burglary and shelling, as well as general doors with cantilevered bands (as in Fig. 1 shown) with narrower gap masses, so less distance between the facing end faces of the two wings are equipped.

The construction according to the invention can also be used to ensure the proper functioning of closing sequence control of double-leaf doors. Closing sequence controls in this sense are devices that should ensure that the active leaf can be closed only after the inactive leaf. However, many of these devices only work flawlessly when the active leaf in the opening movement is clearly ahead of the inactive leaf.
