Definitions

  • the invention relates to a closing sequence control and locking device for double-leaf doors, in particular fire doors, which are equipped with an automatic closing device in which a stop is provided for the active leaf, which protrudes into the pivoting path of the active leaf when the standing leaf is outside the closed position and preferably via a flexible element connected to a contact element to the standing wing and adjustable by the latter, whereby the stop is movable out of the pivoting path of the active wing and this can be pivoted into the closed position.
  • the standing leaf normally remaining in the closed position, the stop fold of which lies in the closing direction of the door in front of the stop fold of the active leaf, must first assume its closed position, whereupon the active leaf can then be pivoted into the closed position. Otherwise the door is not properly closed and no fire compartment is guaranteed.
  • double-leaf doors are generally held in their open position and the holding device releases both door leaves only in the event of a fire. Thereafter, they are moved into their closed position under the action of the locking device panned. The sequence described above is also required to properly close the door.
  • a locking sequence controller is known from US Pat. No. 4,146,994, in which an adjusting rail is formed in the region of the pivoting path of the standing leaf with an inclined surface on which an edge of the standing leaf runs. As a result, the adjusting rail is displaced, whereupon the active leaf previously held in the open position by a stop on this adjusting rail also reaches its closed position.
  • this construction requires very high frictional forces and an unfavorable introduction of the actuating forces into the rail, so that their functionality is questioned.
  • the rail provided above the door leaf is freely accessible, which creates the risk of unauthorized manipulation, which can also impair the function.
  • the rail is preferably arranged in the joint standing between the door leaves and the horizontal bar of the door frame and is formed in the region of the outer lateral end faces of the standing leaf each with a downwardly projecting bend.
  • this bend comes into contact with this bend and thereby moves the rail together with the stop which has previously held the active wing in the open position.
  • the rail of this construction is also accessible, albeit to a greater extent, from the outside, which means that manipulation is not yet completely ruled out.
  • the opening of the active leaf against the stop creates deforming forces which can adversely affect the smooth displacement of the rail and thus the safe functioning of the closing sequence control device.
  • EP-PS 166 859 a device for regulating the closing sequence of hydraulic floor door closers is known from EP-PS 166 859.
  • This device is therefore limited to a special system of closing devices for the door leaves and has a relatively complex construction due to the necessary valve units and the construction associated therewith.
  • Said valve unit influences the flow of the hydraulic fluid of the active leaf during the closing process from one side of the damping piston to the other side of this piston. It is controlled by an actuating unit from the standing wing, wherein, for example, a lever pivoted from the standing wing is coupled to said valve unit via a mechanical, hydraulic or electrical control connection.
  • a disc is specified which is connected in a rotationally fixed manner directly to the axis of the door closer of the standing leaf, and has a partially annular elongated hole in which a Bowden cable is slidably mounted as a mechanical control connection for the valve unit.
  • the hydraulic variant does not have a mechanical stop for the active leaf, and the valve device regulating the closing sequence is controlled by an element that is connected to the standing leaf in a rotationally fixed manner, or an actuating lever that is located near the hinge axis of the standing wing.
  • the object on which the invention is based is to provide a closing sequence control and locking device in which the disadvantages of the previous designs are avoided and which are universal with relatively little effort, i.e. is applicable to all locking systems.
  • Another object was to design the device in such a way that, in addition to its function of pivoting the two wings in a certain order, an automatic locking of the standing wing in the closed position is possible with the active wing in the closed position.
  • the stop is formed by a hydraulic cylinder or a lever pivotable essentially in the door plane, the contact element can be rotated about an axis lying essentially parallel to the door plane and to the hinge axis and with a recess for a part of the standing wing and the connecting element runs inside the upper horizontal bar or the door frame.
  • the contact element is designed as a disc, the recess of which engages behind part of the standing wing in the closed state in the pivoting direction of the standing wing and the contact element is blocked by the active wing as soon as the latter is in the closed position.
  • Fig. 1 the area of the upper corner of the door frame on the side of the active leaf of a double-leaf door is shown. With 1 the upper horizontal bar of the door structure is designated.
  • the door frame 2 delimits the door opening all around and between the door frame 2 and the active leaf 3 there is a small space, the frame lights 4, which is covered by the door rebate.
  • the stop on which the active leaf 3 runs as long as the standing leaf (not shown in FIG. 1) is in the open position is formed by a lever 5 which can be pivoted substantially in the plane of the door.
  • the position of the lever 5 blocking the active leaf is shown with solid lines, while the lever 5 in the position shown in broken lines is removed from the pivoting path of the active leaf 3, whereby this can preferably be brought into its closed position by an automatic closing device, not shown.
  • a hydraulic cylinder can be provided, which moves a stop element into the pivoting path of the active leaf 3 by means of a linear lifting movement.
  • the pivoting in and out of the lever 5 or the lifting movement of the hydraulic cylinder is controlled by connecting the parts mentioned with a contact element 6 which interacts with the standing leaf 8.
  • any stop elements which can be pivoted into the pivoting path of the active leaf or inserted in any other way can be provided.
  • the active leaf 3 must be kept open in a certain position. This position depends on the dimensions of the rebate on the respective door leaf, so that its exact position can vary to a certain extent. Relatively wide open and thus reliable stop positions for the active leaf 3 result when the lever 5 is arranged in the vicinity of the door hinges of the active leaf 3 and at least part 5 'of the lever 5 can be pivoted from above into the upper frame clearing 4 of the door.
  • the pivoting in and out of the lever 5 or the stroke movement of the cylinder etc. is controlled by the contact element 6 shown in FIG. 2, which can be rotated about an axis A lying essentially parallel to the door plane and with a recess 7 for part of the standing leaf 8 is provided.
  • the lever 5 is connected to the contact element 6 via a preferably flexible element 9 which runs inside the upper beam 1 or the door frame 2.
  • this element 9 can be entirely mechanical, i. H. for example as a cable, chain or the like.
  • a hydraulic connecting line between contact element 6 and lever 5 or hydraulic cylinder would also be conceivable. Just like a combination of these connection types.
  • the contact element 6 is arranged in or on the upper door beam in the vicinity of the end face of the standing leaf 8 facing the active leaf 3.
  • the contact element 6 is arranged in an area in which the standing wing 8 travels the greatest distance when pivoted by a certain angle and can therefore deflect the contact element 6 by the relatively largest amplitudes.
  • the part of the standing wing 8, which comes into contact with the contact element 6, is preferably designed as a pin 8 'projecting from the standing wing 8 upwards.
  • Spring elements can advantageously be provided in order to pivot the lever 5 or the hydraulic cylinder and / or to hold them in the pivoted-out position and the contact element 6 in a rotational position in which its recess 7 is directed towards the pivoted-out standing leaf 8.
  • the spring elements can be designed as torsion springs about the axes of rotation or pivoting A, B of the contact element 6 or the lever 5 or as a compression or tension spring in the direction of the movement of the contact element 6 or the lever 5, preferably a compression spring 12 arranged between lever 5 and connecting element 9 (see Fig. 1).
  • the torsion spring provided in the contact element 6 causes the contact element 6 to remain in one position or to be pushed back into the position in which, for example, the bolt 8 'into the recess 7, even in the event of external influences, such as human manipulation, wind or building vibrations of the contact element 6 can be introduced if the Standing leaf 8 is brought into the closed position. Otherwise, said bolt 8 'could otherwise run out of the recess 7 onto the contact element 6, as a result of which a complete and correct closing of the standing leaf 8 and thus also of the active leaf 3 is prevented.
  • the flexible connecting element 9 is suitable for transmitting tensile and compressive forces, the spring element, which is in connection with the lever 5, is unnecessary.
  • a connecting element 9 can preferably be designed as a Bowden cable, if necessary also as a metal rod or hydraulic connecting line.
  • the variant in which a spring is provided at the stop 5 for the active leaf 3 and the contact element 6, has been found to be particularly favorable during construction with the door already in use with the closing sequence control and locking device according to the invention.
  • the stop element In order to avoid damage to the stop element 5 or the active leaf due to carelessness, the stop element is fixed in its pivoted-in position. So that both door leaves can now be closed correctly, the contact element 6 must be held in a position when the door leaf is open, for example that the bolt 8 'of the standing leaf 8 can be inserted into the recess 7 of the contact element 6. This function is effected by the spring provided in the contact element 6.
  • the variant with two springs has the advantage that if one spring is damaged, the function of the door can be maintained and the springs themselves can be of smaller dimensions.
  • the lever 5 can advantageously also be largely arranged inside the upper door beam 1 or the upper part of the door frame 2.
  • the contact element 6, which has not been described in detail so far, is advantageously designed as a disc, according to a further feature of the invention, the recess 7 of which engages behind a part 8 'of the standing leaf 8 in the closed state in the swiveling direction of the standing leaf, and it is further provided that the contact element 6 is removed from the active leaf 3 is blocked as soon as the latter is in the closed position.
  • the contact element 6 preferably on its side facing the active leaf 3 has a stop surface 10 for a part 3 'of the active leaf 3, on which stop surface 10 said part 3' of the active leaf 3 comes into contact with the door closed and thus a rotation of the contact element 6 prevented.
  • Fig. 2 an embodiment of such a disc 6 is shown.
  • This is preferably provided with an axis of rotation D arranged parallel to the pivot axis of the standing wing 8, which is preferably outside the center of the disc 6.
  • the axis of rotation D of the disc 6 lies with respect to the center on the side of the disc 6 opposite the pivoting direction of the door leaf 6.
  • the stop surface 10 not only performs a substantially circular pivoting movement, as with a central axis of rotation, but that the stop surface 10 is also pressed in the direction of the part 3 'when the standing wing 8 is applied in the pivoting direction and thereby the bolt 8 'presses the recess 7 of the disc 6 in the pivoting direction.
  • the part 3 'of the active leaf 3 prevents this movement of the stop surface 10 when the active leaf 3 is closed, so that even with very strong force on the standing leaf 8 in the pivoting direction this remains locked when the active leaf 3 is closed.
  • the axis of rotation D of the pane 6 lies outside of its center on the side opposite the pivoting direction.
  • the surface 10 can also be designed obliquely and run in the pivoting direction of the door leaf 3 to the door center plane or the door center rebate (shown in Fig. 4 and dashed lines with 10 ').
  • the part 3 'of the active leaf 3 which comes to rest on the stop surface, a surface corresponding to this surface, preferably also flat surface 3'a, so that the largest possible contact surface for transmitting the fixing effect of the disc 6 is given by said part 3' .
  • part 3 ' is provided with an acute-angled edge 3b and the disk 6 with a corresponding recess 6b.
  • the edge 3'b of part 3 ' points in the pivoting direction and towards the door center plane and is formed by a side of part 3' forming an acute angle with the flat surface 3'a.
  • the recess 6b of the disc 6 is preferably realized as a cutout with the same angle between its sides as the angle of the edge 3'b.
  • the recess 6b is provided with respect to the stop surface 10 at its end located in the pivoting direction. A slight offset of said recess 6b in the direction of the door center or the door center rebate is also favorable.
  • the function of the system from edge 3'b and recess 6b is that with simultaneous and in the same direction swiveling movement of both door leaves 3.8 of the bolt 8 'of the standing leaf, the disc 6 rotates such that the recess 6b in the pivoting path of the part 3 'of the active leaf 3 is pivoted.
  • the acute-angled edge 3'b engages in the recess 6b and prevents further pivoting of the active leaf 3.
  • further rotation of the disc 6 about the axis of rotation D is prevented, so that the standing leaf 8 is also blocked is because the bolt 8 'has not yet emerged from the recess 7 of the disc 6.
  • this also makes the lever arm of the disk 6 on the side of the active leaf 3 larger than that on the side of the standing leaf, which also improves the holding and locking effect.
  • This feature allows that in connection with the outer contours of the pane 6 shown in FIG. 4, even when rotated, the latter does not protrude beyond a certain minimum width of the door beam and thereby allows the closing sequence control and locking device according to the invention to be installed even with relatively narrow door frames.
  • the underside of the disc 6 is at most flush with the underside of the upper part of the door frame 2.
  • FIG. 3 shows a section along the line III-III of FIG. 2. It can clearly be seen from the standing wing 8 projecting bolt 8 '.
  • the bolt 8 ' is located inside the recess 7 of the turntable 6, which can rotate about a bearing pin 11.
  • a torsion spring which the disc 6 in the deflected Holds position when the standing leaf 8 is open.
  • the installation space of the disk 6 is closed by a housing cover 13. In the embodiment shown, a torsion spring is not provided.
