Description

The invention relates to a device for regulating the closing order of a double-leaf door, comprising an active door leaf and a passive door leaf, which are rotatably mounted in a fixed door frame for closing in opposite directions and provided with handles disposed first ends rotatably on the door wings or on the control

The door leaf members and the other free ends provided with pins pivotally and slidably in a guide connected rigidly to the door frame.

BACKGROUND OF THE INVENTION

Double-leaf doors are usually installed in corridors with a temporarily or permanently large pedestrian or driving traffic. Double-leaf doors do not always have the same function of door leaves. Often one door leaf is active and opens in normal operation and the other door leaf is passive and opens only in special cases, eg when carrying large objects, when passing large vehicles or evacuating people in fires. The active door leaf has on the side edge adjacent to the passive door leaf a cover strip which, when the two door leaves are closed, is adjacent to the passive door leaf and covers the slot formed between the two door leaves after they are closed. The cover strip does not allow the passive door leaf to open before opening the active door leaf or to close after closing the active door leaf. The active door leaf must therefore be closed only after the passive door leaf. In order for the passive door leaf to be opened or closed independently of the active door leaf position, the active door leaf must be opened to a certain minimum angle of the so-called holding position. Numerous devices arranged on the door wings and connected to the door frame are used to ensure the order of closing and opening the door leaves without colliding with each other.

-2docked in the wall. They generally include a locking device for stopping the active door leaf in the holding position, which allows the passive door leaf to be opened and a release device for releasing the active door leaf from the holding position.

WO 2010/130440 discloses a device for regulating the closing order of a double-leaf door, consisting of door closers with control arms and guiding wings and multi-arm mechanisms arranged on each door leaf and connected by rod adjusters, provided with a locking device for locking the active door leaf in position the smallest opening allowing free passage of the passive door leaf and a release device for releasing the locking device at a given position of the passive door leaf. The described device, which aims to reduce the stopping angle of the active leaf in the holding position and to reduce the stress on the door closer control arms, is very complicated in design, has a large number of arms with sensitive bearings, occupies a large space, is difficult to adjust and is expensive.

EP2208846 discloses a device for regulating the closing order of a double-leaf door, on one of which a pivot arm is rotatably mounted on one door leaf, the other end of which is pivotally connected to a guide stone, displaceably mounted in a guide connected to the door frame and engaging . a release stone, also displaceably disposed in a guide connected firmly to the door frame and connected to other parts for regulating the closing order of the second door leaf. In the case of a double-leaf door closing control device, it is necessary that the active door leaf is opened sufficiently in the so-called waiting position when the passive door leaf is opened and the passive door leaf does not overtake when the active door leaf is closed. This requirement can be met more easily if the swinging arms of the door leaves are sufficiently long. However, the large length of the swinging arms is disadvantageous from an aesthetic point of view when all the parts arranged between the guide rail on the door frame and

door wings should be as visible and therefore as small as possible. In the case of short swinging arms when closing the door leaf at a low angle position between the swinging arm and the guide groove, the linear transmission between the door leaf and the guide stone decreases and the guide stone stops in a guide fixed to the door frame or moves in the opposite direction. To eliminate the disadvantage of slowed movement of the guide stone when closing the door leaf, the guide stone is provided with a protrusion and a blocking resp. the release stone has a curved, preferably spiral surface on the contact side, and due to the engagement of the guide stone projection with the curved surface of the blocking or blocking surface. the blocking or linear movement of the blocking or releasing stone occurs. even at very small angles between the swing arm and the guide groove. Blocking resp. release of the active door leaf by sliding movement of the blocking resp. The release stone in the guide connected to the door frame appears to be disadvantageous due to insufficient, inaccurate and unreliable transmission between the swing arm and the locking or locking mechanism. with a release stone. The device for regulating the closing order of double doors according to EP2208846 appears too complex and expensive.

US2003 / 145522 discloses a device for regulating the closing order of a double-leaf door, comprising two door wings with door closers with actuating arms, the free ends of which are rotatably mounted on sliders mounted slidingly in a guide arranged above the door wings and attached to the door frame. To the free end of the control arm of the passive door leaf is attached an extension ending with a shaped projection. A guide element is arranged in the guide between the sliders, consisting of a displaceable stone supported in sliding in the guide and a two-arm transmission lever mounted pivotably on a pin connected to the guide or door frame. The transmission element has a recess with which one arm of the two-arm transmission lever engages, the other arm extends from the guide and engages with the shaped projection of the extension of the control arm of the passive door leaf. Action

-4-shaped projection of the extension on the second lever arm in the direction of the door hinges moves the first lever arm the sliding stone away from the door hinges against the free door leaf slider of the active door leaf, thereby limiting the active leaf in closing to the minimum waiting angle required to close the door leaf, which must precede the closing of the active door leaf. The double-door closing control device is of a simple construction, but the engagement of the shaped projection of the passive door leaf arm extension with the second gear lever arm and the adjustment of the wait angle of the active door leaf are difficult to adjust and inaccurate.

In accordance with FIG. Door leaf 1 is an active door leaf that opens and closes during normal operation and door leaf 2 is a passive door leaf that is closed during normal operation and only opens when there is a special need when a larger object needs to be passed, or in the event of fire evacuation. A guide 31 is fixed above the door wings 1,2 fixedly connected to the door frame 3. The door leaf 1, 2 is adjacent to the frame 2 after closing. The active door leaf 1 has, on the side edge adjacent to the passive door leaf 2, a cover strip 1 located on the outside of the active door leaf 1 facing away from the frame 2 ^and covering a gap formed between the two door wings. The cover strip Ί does not allow the passive door leaf 2 to be opened before the active door leaf 3 is opened or closed after the active door leaf 1 is closed. In order for the passive door leaf 2 to be opened or closed independently of the active door leaf position 1, the door leaf 3 must remain open to a minimum angle of 5? holding positions. On the door wings

2. Equivalent actuating members 10, 20 are mounted on which the rods 11, 21 are rotatably mounted at their first ends 12, 22. The actuating members 10, 20 turn the rods 11, 22 forced, for example hydraulically, or may be passive hydraulic closers. The second free ends 13, 23 of the rods 11, 21 are provided with pins 15, 25 on which the pulleys 14, 24 are rotatably mounted. The pins 15, 25 extend through the pulleys 14, 24 and extend their free ends from the pulleys 14, 24. 24 are mounted movably in the conduit 31 so that they roll around the conduit 31 in the conduit. The guide 31 has an inner dimension corresponding to the diameter of the pulleys 14, 24 so as to roll the pulleys 14, 24 as they move in the guide 31. The pulleys 14, 24 approach each other when closing the door leaves 1, 2 and 1, 2 move away from each other. In the guide 31, a two-arm coordination lever 4 is arranged between the pins 15, 25 of the pulleys 14, 24, arranged in the guide 31 pivotable about the axis of the pin 32, whose axis γ is vertical, for example, parallel to the axes of the pins 15, 25 of the door wings 1 on the pins 5, 6. The pin 32 is received in a crosshead 35 which is fixedly fixed in the guide 31 and its position in the guide 31 is adjustable by release and displacement. The pin 32 may also be arranged horizontally and the γ axis may be horizontal when the pins 15, 25 are provided with horizontal (not shown)

The projections whose paths extend into the inclined surface 42 and the blocking surface 46 may be arranged in an open groove 37 formed in the crusher 35 and provided with oppositely angled extensions 38 on the opposite sides to allow the coordinate lever 4 to swing. .

The two-arm coordination lever 4 has a bar shape with two arms, a first control arm 41 with a longitudinal axis and a second locking arm 45 with a longitudinal axis β extending parallel to each other but offset in opposite directions from the axis γ of the pin 32. "z".

The control arm 41 of the two-arm coordination lever 4 has a taper

In the locking position, the inclined surface 42 of the control arm 41 interferes with the travel of the pin 25 of the pulley 24 disposed on the free end 23 of the rod 21 of the passive door 2 and the stop surface 46 of the locking arm. 45 extends into the path of movement of the pin 15 of the roller 14 arranged at the free end 13 of the rod 11 of the active door leaf 1.

Referring to FIG. 2, in the release position of the coordinating lever 4, when the passive door leaf 2 is closed, the control arm 41 is deflected from the locking position by pivoting due to engagement of the pin 25 1 of the free end 23 of the rod 21 first with the inclined surface 42 of the control arm 41 the flat shoulder 47 of the control arm 41. With the deflection of the control arm 41, the locking arm 45 deflects in the opposite direction, the stop surface 46 of the locking arm 45 lies outside the travel path of the free end 13 of the active door leaf 11 and releases movement of the free end 13 of the rod 11 along the shoulder 48 In the arm 45, the active door leaf 11 stops being locked in the holding position and can be closed. The exact angular position of the co-ordinating lever 4, respectively. the position of the inclined surfaces 42 of the control arm 41 relative to the pin 25 and the position of the stop surface 46 of the locking arm 45 relative to the pin 15 are adjusted by the stop of the adjusting screw 34 to one of the legs 41, 45 and spring 33 which is in force contact with the other of the legs 41 , 45 and generates a torque against the stop 34. In a certain closing position of the passive door leaf 2, the active door leaf 1 can be released from the holding position, since the active leaf 1 closes after the passive door leaf 2 or the active leaf 1 with its cover strip 2 closes the passive door leaf 2. The passive door leaf 2 can be adjusted by adjusting the position of the crosshead 35, selecting the length of the control arm 41 or the length of the rod 21 of the passive door leaf 2. According to a preferred embodiment, not shown in the drawings, the control arm 41 and the locking arm 45 may be tapered in the direction of the ends of the control arm 41 and the locking arm 45 on the sides facing the guide walls.
