Definitions

  • the invention relates to a door closer with a housing in which a shaft for connection to a door or the like is mounted, the shaft being lockable in at least one position by a spring-loaded locking element.
  • Such door closers are well known. Such door closers usually have a housing in which a shaft which can be connected to a door or the like, a spring-loaded locking element and a brake piston are arranged. Locking element and brake piston are essentially one behind the other on opposite sides of the shaft so that overall an elongated housing shape results. In many cases, however, such a shape of the housing is difficult to accommodate, since it is often not possible to provide an elongated recess for the housing, particularly in the base area. Such a door closer can be found in DE 40 38 720 C2 as an overhead door closer and DE 27 55 787 A1 as a floor door closer.
  • the main part (the housing) consists of a square body, to which a pipe is firmly connected at right angles to its axis.
  • this tube there is another short tube with a bottom, to which the support carrying the roller is attached.
  • the two nested tubes have a steel planchette between them. As a result, the abrasion is reduced, and at the same time the tubes cannot be heat-treated.
  • the spring is mounted in a right-angled, preferably tubular cartridge protruding from the housing.
  • B. is interchangeably connected to the housing. This not only enables the elements of the door closer to be arranged in a very small space, but also enables the spring-receiving sleeve to be fitted adaptively, so that the cartridge can be replaced quickly and easily.
  • the construction of the locking element is particularly simple if, according to an advantageous embodiment, the locking element has a cup-shaped insert which is slidably mounted in the tubular cartridge. As a result of this arrangement, a tilt-free guidance of the locking element in the cartridge can be ensured.
  • a carrier protrudes from the bottom of the pot-shaped insert into the housing and bears a role that interacts with the shaft.
  • the cup-shaped insert is advantageously loaded in the direction of the housing by a spring arranged in the sleeve. In this way, reliable locking of the locking element on the shaft is guaranteed in every position.
  • the shaft is acted upon by a spring-loaded brake piston mounted in the housing.
  • a seal is advantageously provided between the wall of the housing and the brake piston.
  • the brake piston can be locked in a predetermined position via a valve arrangement.
  • the valve arrangement advantageously has a control valve and a check valve influencing the outflow from the control valve.
  • the outflow of the brake fluid can thus be easily controlled via the control valve.
  • BESTATIGUNGSKOPIE controls or be prevented, so that no movement of the brake piston is possible and the door is locked in a certain position.
  • the shut-off valve opens automatically in the event of overpressure and the door closes due to the spring force.
  • the check valve can also be actuated electromagnetically.
  • the brake piston is provided with a roller which acts on an eccentric disk arranged on the shaft.
  • the brake piston can also be connected to the shaft via a rocker arm and an eccentric disk. This construction has the advantage of a uniform path through a positive guidance.
  • Figure 1 A cross section through the door closer according to the invention
  • BESTATIGUNGSKOPIE Figure 2 another cross section through the door closer according to the invention.
  • Figure 3 shows a cross section through a further embodiment of the door closer according to the invention.
  • the door closer has an essentially rectangular housing 1, in which a shaft 2, which can be connected to a door or the like, is mounted.
  • the shaft 2 has an eccentric disk 3, which is in engagement with a roller 5 mounted on a brake piston 4.
  • the brake piston 4 in turn is mounted in a longitudinally displaceable manner in the housing 1, wherein it is pressed in the direction of the shaft 2 by a spring 6 likewise mounted in the housing 1.
  • a seal 7 is arranged in a circumferential groove, which is supported on the wall of the housing 1.
  • a control valve 8 is provided, with the aid of which the movement of the brake piston 4 can be influenced by regulating the flow of the brake fluid in the housing 1.
  • the door or the like can be locked in a certain position, for example in the open position.
  • a check valve 9 which closes automatically when the door is deliberately moved.
  • a small piston 10 or a valve seat can be provided which, in the position shown, is caused by friction of an O-ring 11 on the valve seat an outflow of the brake fluid prevented, but at increased pressure in the brake fluid by z. B. deliberately moves the door so that the lock is released and the door can be moved.
  • electromagnetic actuation of the blocking valve 9 is also possible, so that the door closer according to the invention can also be used in escape and rescue routes.
  • a tubular sleeve 12 or cartridge extends at right angles to the housing 1 and is removably arranged on the housing 1 and in which a locking element 13 is mounted so as to be longitudinally displaceable.
  • the locking element 13 has a cup-shaped insert 14 which is mounted in the tubular sleeve 12 and is urged in the direction of the shaft 2 by a spring 15 also mounted in the sleeve 12.
  • a carrier 16 protrudes towards the housing 1, which carries a roller 17 at its front end, which, for. B. engages in a recess 18 on the shaft 2 or the eccentric 3.
  • a friction and / or wear-reducing coating or insert 19 e.g. B. made of steel.
  • FIG. 3 shows an alternative embodiment of the door closer according to the invention, in which the brake piston 4 is connected to the shaft 2 via a rocker 20 and an eccentric disc 21.
  • the door closer according to the invention is preferably intended as a floor door closer, but can also be used for other installation positions.

Abstract

L'invention concerne un ferme-porte automatique comprenant un boîtier (1), dans lequel est logée une broche (2) de liaison avec la porte ou un élément analogue, cette broche (2) pouvant être bloquée dans au moins une position par un élément de blocage (13) commandé par ressort. L'invention vise à créer un ferme-porte automatique dont le boîtier est plus compact et qui est ainsi plus aisé à monter. A cet effet, le ressort (15) qui commande l'élément de blocage (13) est perpendiculaire au boîtier (1).
