Definitions

• the invention relates to a closing sequence controller for a self-closing door comprising a fixed leaf and an active leaf, the active leaf being lockable by means of a locking mechanism which can be released by the fixed leaf.
• Double-leaf doors of the type mentioned overlap one another in the central region, so that one door leaf forming a passive leaf has a stop for the other door leaf forming the active leaf, a specific closing sequence being required for their tight closure if the door leaves are to be properly closed.
• closing sequence controllers are used, which always ensure the sequence of the transitions of the two door leaves into the closed position, which sequence is necessary for the aforementioned correct closing.
• a certain sequence of the closing movement of both door leaves is also necessary in order to only allow the active leaf, which is usually provided with a lock, to reach the closed position only when the passive leaf forming the door stop, which generally has the striking plate or the like, is closed.
• EP 0 141 902 A2 discloses a closing sequence controller for a self-closing door comprising a fixed leaf and an active leaf, the door leaves of which are connected to the door frame via a door closer.
• the closing sequence controller is designed in such a way that an actuator movable in two switch positions is arranged in the swivel axis area of the passive leaf and interacts with a connecting element in the form of a Bowden cable that extends as far as the door closer of the active leaf.
• the object of the present invention is therefore to eliminate the disadvantages mentioned above and to create a mechanical closing sequence controller which ensures a secure closing sequence of a door guaranteed, but achieved in a visually appealing form and with as few external components as possible, which do not protrude beyond the door level.
• the closing sequence controller for a self-closing door comprising a fixed leaf and an active leaf, the active leaf being lockable by means of a locking mechanism which can be released by the fixed leaf, has the following features:
• the passive leaf is provided with a cam disc
• the cam disc is operatively connected via an actuating element to a brake acting on the active leaf.
• a closing sequence controller is provided with few and simply constructed components, which ensures a secure closing sequence.
• the design also has the advantage that the entire closing sequence controller is very compact and that all components can be hidden from the outside, so that there are no visual impairments and components do not protrude outwards.
• the individual components can be made relatively small, so that the closing sequence controller according to the invention takes up little space and z. B. can be accommodated in the floor area of the door.
• the closing sequence controller according to the present invention can also be easily installed or removed due to its low weight, and can also be retrofitted.
• the closing sequence controller has an overload protection device which counteracts destruction of the closing sequence controller.
• Figure 1 The structure of a closing sequence controller according to a first embodiment
• Figure 2 a second embodiment of the invention
• FIG. 1 shows the structure of a closing sequence controller according to a first embodiment of the present invention.
• the active leaf, the passive leaf and the other parts of a door are general prior art and are therefore not shown or explained in more detail here. Rather, only the closing sequence controller according to the invention is described in its individual parts.
• the closing sequence controller according to the invention can preferably be used and installed in floor door closers. Therefore, only one axis 1 of the passive leaf and one axis 2 of the active leaf are shown of the two door leaves. Both axes 1, 2 are mounted on a base plate 3 and 4, respectively.
• a cam disk 5 is arranged concentrically on the axis 1 of the passive leaf and has a substantially circular peripheral surface which is interrupted at one point by a recess 5a, as can be seen in detail from FIGS. 1 or 2.
• a two-armed lever 6 is also mounted on the base plate 3 and bears on the circumferential surface of the cam disk 5 with a nose 6 a arranged at one end thereof.
• the nose 6a can be in one piece with the two-armed lever 6 connected projection (see FIG. 1) or as a rotatable roller (see FIG. 2).
• the other end of the two-armed lever 6 is connected to an actuating element 7, which is preferably designed as a Bowden cable, but can also be formed by a rod or the like.
• the actuating element 7 is mounted on the base plate 3 by means of an adjusting screw 8.
• the other end of the actuating element 7 is connected to a brake 9.
• the brake 9 is mounted on the base plate 4, which also receives the axis 2 of the active leaf. It is preferably designed as a shoe brake with two brake shoes 9a and provided on the inside with a friction lining 9b.
• the two brake shoes 9a encompass a freewheel 10 which is arranged on the axis 2 of the active leaf.
• the two brake shoes 9a are articulated on one side, while their other ends are connected to the actuating element 7. Between the two brake shoes 9a there is also a compression spring 11 which presses the two brake shoes 9a apart.
• an overload safety device preferably designed as an overload spring 12, is provided.
• the cam 5 actuates the brake 9 via the two-armed lever 6 and the actuating element 7, the movement of the active leaf can be influenced, so that it is ensured that the passive leaf always comes into the closed position before the active leaf.
