Definitions

  • the invention relates to a hydraulic-mechanical closing sequence control for double-leaf doors.
  • Such a closing sequence control is known from EP 0 141 902.
  • an actuator interacting with a fixed leaf actuates a Bowden cable, which controls a valve arranged on a moving leaf. If the valve is opened via the Bowden cable, the hydraulic fluid can flow out of the locking piston and thus ensure that the passive leaf is always closed before the active leaf.
  • the transmission element namely the Bowden cable
  • the Bowden cable fails, z. B. by wrong setting, wrong length of the Bowden cable, loosening the cable clamps, etc., it happens that the correct closed position of the folded door leaf (active and passive leaf) is not maintained.
  • closing sequence controls are usually used in door systems in fire compartments, there is an increased risk potential if the double-leaf door is not closed correctly.
  • Another closing sequence control is known from DE 32 04 975 A1, in which a control valve is provided which is connected directly or indirectly to the passive leaf.
  • the axis of a door closer for the passive leaf is provided with a toothed wheel which meshes with a toothed rack arranged in a piston, so that a rotation of the axis of the door closer is converted into a translatory movement of the piston.
  • the piston controls the flow of hydraulic fluid on the active leaf
  • BESTATIGUNGSKOPIE ensures that the active leaf cannot be closed in front of the passive leaf.
  • the object of the present invention is therefore to further develop the state of the art and to create a hydraulic-mechanical closing sequence control which ensures a secure closing sequence of a double-leaf door, but achieves this with as few components as possible and also of simple construction. Furthermore, the closing sequence control should be retrofittable.
  • the hydraulic-mechanical closing sequence control is for double-leaf doors that have a passive leaf and a active leaf, both the fixed leaf and the active leaf being acted upon by a hydraulically actuated door closer or drive, which is provided with an axis on which a linkage engages.

  • the design also has the advantage that the entire closing sequence control is very compact and can therefore be easily and conveniently installed and removed, e.g. B. for a repair or for maintenance purposes. Since it consists of only a few and relatively small individual parts, it is not just the storage of the entire closing sequence control, but 'the provision of individual or spare parts simple and straightforward and requires little space.
  • the closing sequence control according to the present invention can also be installed or removed without problems because of its low weight. Due to the arrangement of the valve on the passive leaf, a higher reaction speed is also achieved.
  • the entire closing sequence control is inexpensive, can be easily installed in a system carrier and enables easy adjustment. Pre-assembly is also possible. Through the direct control, without the use of intermediate links, the position of the door leaf can be recognized directly. Furthermore, there is no interference in the hydraulic circuit of the active leaf by elements of the door closer of the passive leaf.
  • Door closers are understood to mean both classic door closers and door drives with an electrohydraulic opening aid and electrohydraulic door drives.
  • door drives also come under the term door closer.
  • the door closer of the active leaf is controlled via a hydraulic connection. This ensures simple control and is also extremely inexpensive.

  • a slide rail can also be used, in which, for. B. additional chambers are available or two hydraulic lines are installed in one chamber.
  • the hydraulic connection consists of hoses.
  • the closing sequence control according to the invention is constructed such that the valve allows unrestricted movement of the active leaf in the open state and blocks movement of the active leaf in the closed state.
  • the valve is only opened in one single position of the cam disc, but is closed in all other positions. This open position is given when the passive leaf remains in its correct closed position or from a certain small opening angle of the passive leaf, which is always smaller than the opening angle of the active leaf. With the exception of this very specific position of the passive leaf, the active leaf can always be moved. In this way, the desired closing sequence control is ensured with the simplest of means. As soon as the passive leaf and the active leaf are opened (both at the same time), only one can the passive leaf can be moved. The active leaf remains in its position and can only be moved again when the passive leaf has reached its closed position or is just before the closed position.

This pin is pressed against the cam disk in an advantageous manner by a spring. This ensures that the pin is always in contact with the cam disc, thus ensuring reliable control of the valve.

Abstract

L'invention concerne une séquence de fermeture mécano-hydraulique d'une porte à double battant comportant un battant fixe et un battant mobile. Le battant fixe comme le battant mobile sont respectivement actionnés par un ferme-porte (1, 2) à commande hydraulique chacun pourvu d'un axe (3). L'invention vise à créer un dispositif de réglage mécano-hydraulique de fermeture garantissant une séquence de fermeture sûre des portes tout en comportant peu de composants de construction simple. A cet effet, une came plate (5) qui est placée sur l'axe du ferme-porte du battant fixe, coopère avec une valve (7) qui commande le ferme-porte du battant mobile ou bien un coulisseau du battant fixe qui coopère avec la valve (7), commande le ferme-porte du battant mobile.
