Description
Schloß für Fallschirm mit Zentralgurtung Die bisher gebräuchlichen Zentralschlösser für Fallschirme, bei denen die Begurtung in dem Schloß zusammenläuft, haben sich als unzuverlässig erwiesen, denn sie haben zu einer Reihe von tödlichen Unfällen geführt, weil bei einem Schlag gegen die Unterseite des Schlosses, also gegen den Verschlußdeckel, die Haltebolzen zurückfedern und somit die Gurtösen der Fallschirmgurte aus dem Schloß herausspringen. Diese unerwünschte Selbstauslösung tritt besonders in Erscheinung bei lockerem Anlegen des Fallschirmes mit losen Gurten, weil durch die beim Absprung auftretenden Beschleunigungen und durch den Stoß das Schloß gegen den Körper des Abspringenden geschleudert und ausgelöst wird, wobei die Gurtösen aus dem Schloß springen und der Benutzer herausfällt.Lock for parachute with central belt The previously common ones Central locks for parachutes, where the straps come together in the lock, have proven to be unreliable as they have resulted in a number of fatal ones Accidents resulted because a blow against the underside of the lock, so spring back against the cover, the retaining bolts and thus the belt loops of the Parachute straps jump out of the lock. This unwanted self-triggering occurs especially when the parachute is put on loosely with loose straps, because due to the accelerations occurring when jumping and the impact that The lock is thrown against the body of the person jumping and is released, whereby the belt loops jump out of the lock and the user falls out.
Um dies zu verhindern, ist das Schloß erfindungsgemäß mit einer Sicherungsscheibe ausgerüstet, die sowohl in gesicherter als auch in ungesicherter Stellung des Schlosses ein Herausschnappen der Gurtösen aus den Haltebolzen zuverlässig vermeidet.To prevent this, the lock is according to the invention with a locking washer equipped, both in the secured and in the unsecured position of the lock reliably prevents the belt loops from snapping out of the retaining bolts.
In Fig. 1 ist das Schloß mit der Sicherungsscheibe 6 im Schnitt dargestellt. Fig.2 zeigt das Schloß von unten mit abgenommenem Deckel 8. Da die Drehscheibe 1 eine Viertelumdrehung beim Drehen macht, zeigt Fig. 2 sowohl den gesicherten als auch den entsicherten Zustand des Schlosses. In beiden Stellungen ist ein Zurückfedern der Haltebolzen 2 unmöglich, da sie durch die Lappen 7 der Sicherungsscheibe 6 daran gehindert werden. Die Sicherungsscheibe 6 ist durch eine Mutter 9, die auf der Verbindungsschraube 3 sitzt, mit der Drehscheibe 1 und dem Nockenzapfen 5 fest verbunden. Durch die Nasen 10, die in den Schlitz 11 des Nockenzapfens 5 eingreifen, wird beim Drehen der Drehscheibe 1 die Sicherungsscheibe 6 mitgenommen. Damit die Gurtösen 4 der Fallschirmgurte einschnappen können, wird die Drehscheibe 1 um eine Achteldrehung zurückgedreht, d. h. in eine Stellung zwischen gesicherter und entsicherter Stellung gedreht, wie in Fig.3 dargestellt. In dieser Stellung sind die Haltebolzen 2 entsichert, und die Gurtösen 4 der Fallschirmgurte können einschnappen. Nach dem Einschnappen wird das Schloß in der gewohnten Form gesichert.In Fig. 1, the lock with the locking washer 6 is shown in section. 2 shows the lock from below with the cover 8 removed makes a quarter turn when turning, Fig. 2 shows both the secured as also the unlocked state of the lock. There is a spring back in both positions the retaining bolt 2 impossible because it is attached to it by the tabs 7 of the locking washer 6 be prevented. The lock washer 6 is secured by a nut 9 on the connecting screw 3 sits, firmly connected to the turntable 1 and the cam pin 5. Through the Lugs 10, which engage in the slot 11 of the cam pin 5, when rotating the turntable 1, the locking washer 6 taken along. So that the belt loops 4 of the Parachute belts can snap into place, the turntable 1 turns an eighth of a turn turned back, d. H. into a position between the locked and unlocked position rotated as shown in Fig.3. In this position, the retaining bolts 2 are unlocked, and the belt loops 4 of the parachute belts can snap into place. After the snap the lock is secured in the usual way.
