Abstract

The door chain damper prevents the chain (3) being torn out and is furnished with a spring (2) to absorb and accordingly cancel out all pressure or impact applied to the door. This prevents the chain being ripped off the door or the fixed dowel (8) from being pulled out. Design details include the hollow steel enclosure (1) as guidable spring housing against end-stop (7), plus tapped dowel (8) socket (5) screwed far enough in to press the pin (4) onto the spring. With increasing door weight this can damage the chain impact points when slammed shut etc. with consequent and progressive weakening of the chain and its security function thus in turn offering release opportunities for the inmates, unless this damped chain is employed.

Description

Die Erfindung betrifft Türen, vorzugsweise bestimmt für den Einbau in Gewahrsamsanstalten und deren spezifischen Anforde­ rungen.The invention relates to doors, preferably intended for Installation in detention centers and their specific requirements stanchions.

Bekannt sind Türsicherungseinrichtungen, über Ketten oder Haken, welche in keinem Fall schlagartige Belastungen dämpfen. Die in massiver Bauweise ausgeführten Gewahrsamstüren setzen durch ihr Eigengewicht, im Zusammenhang mit einer schnellen Öffnungsbewegung, eine relativ hohe Energie frei.Door security devices are known, via chains or Hooks that in no way dampen sudden loads. Set the custody doors in solid construction by its own weight, in connection with a quick Opening movement, a relatively high energy free.

Je größer das Gewicht der Tür und je schneller die Öffnungs­ geschwindigkeit umso größer ist die frei werdende Energie, welche bei ungedämpften Türsicherungsketten schlagartig umgesetzt wird.The greater the weight of the door and the faster the opening speed the greater the released energy, which suddenly with undamped door security chains is implemented.

Eine Beschädigung der Tür- oder Wandbefestigung ist zwangsläufig die Folge.Damage to the door or wall mounting is inevitable the consequence.

In Abhängigkeit von der Türgröße (Eigengewicht) wird die Federstärke ausgelegt.Depending on the door size (dead weight), the Spring strength designed.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine beabsichtigte aber auch ungewollte Beschädigung der Anschlagpunkte der Sicherungskette auszuschließen und damit die Funktion der Sicherung anhaltend zu gewährleisten.The present invention is based on the object an intentional but also unwanted damage to the Exclude anchor points of the safety chain and thus ensuring the continued function of the fuse.

Die Erfindung wird nachstehend anhand eines Ausführungs­ beispiels näher erläutert.The invention is based on an embodiment example explained in more detail.

Es zeigtIt shows

Fig. 1 eine längs ausgeführte Schnittdarstellung des Dämpfungselementes; Figure 1 is a longitudinal sectional view of the damping element.

Fig. 2 zeigt in der Schnittdarstellung den ausgedrehten Hohl­ körper aus Stahl (1), welcher durch einen innen liegenden Absatz (7) die aufgenommene Feder (2) sicher führt und Halt gibt. Fig. 2 shows in the sectional view the turned hollow body made of steel ( 1 ), which leads through an internal shoulder ( 7 ), the spring ( 2 ) safely and gives support.

Das in die hintere Stirnwand einzudrehende Gewindestück (5) erhält über ein Innengewinde (6) den dazu passenden Schwer­ lastdübel (8), soweit eingedreht (in Abhängigkeit von der Länge der verwendeten Feder), bis das Gewindestück den ein­ gelegten Zylinderstift (4) fest auf die Feder drückt.The threaded piece ( 5 ) to be screwed into the rear end wall receives the appropriate heavy-duty dowel ( 8 ) via an internal thread ( 6 ), as far as screwed in (depending on the length of the spring used) until the threaded piece fixes the inserted cylindrical pin ( 4 ) presses on the spring.

Damit kann auch, wenn erforderlich, eine gewisse Vorspannung erzeugt werden.This can also, if necessary, a certain preload be generated.

Claims (1)

Sicherungskette mit Federdämpfung für Gewahrsamtüren, dadurch gekennzeichnet, daß die integrierte Federdämpfung ein Abreißen der Türsicherungskette verhindert.
Auf die Tür einwirkende Kräfte, durch Druck oder Schlag, werden durch die Feder aufgenommen und damit unwirksam gemacht. Ein Losreißen der Sicherungskette von der Tür als auch das Rausreißen des Wanddübels wird damit unmöglich gemacht.Safety chain with spring damping for prison doors, characterized in that the integrated spring damping prevents the door safety chain from being torn off.
Forces acting on the door, through pressure or impact, are absorbed by the spring and thus rendered ineffective. This makes it impossible to tear the safety chain out of the door or pull out the wall plug.
