A portable privacy lock is disclosed for use in securing a door that swings on hinges from an open position to a closed position in which the edge of the door opposite its hinged side is adjacent to a closure surface with a clearance gap therebetween. As shown in Figure 1, lock 10 includes a flexible webbing 12 which has a first end 14 and a second end 16, and which is provided with a plurality of holes between said first and second ends (three such holes, 48, 50 and 52, are illustrated). The lock also includes a first securing plate 18 that is attached to the first end of the webbing and asecond securing plate 20 that is attached to the webbing at an intermediate position between the first and second ends thereof. The second plate is also provided with a hole 46 that is aligned with one of the holes in the webbing. The lock also includes a latch 26 that is adapted to receive a drawstring and to releasably engage it from motion with respect thereto, and a drawstring 28, one end of which is attached to the first plate or to the first end of the webbing. The drawstring is threaded through the holes in the webbing and the second plate to engagement with the latch. The lock is utilized by inserting the first plate through the clearance gap between the door and its adjacent closure surface. The latch is disengaged from the drawstring so that the drawstring may be pulled to fold the webbing to move the second plate into position across the clearance gap and on the opposite side thereof from the first plate, so as to secure the door from motion with respect to the adjacent closure surface. The latch may then be engaged to hold the drawstring so as to maintain the plates in position with respect to each other.
Cette invention concerne une serrure portative verrouillable de l'intérieur servant à bloquer en position fermée une porte battante dont la rive opposée aux charnières a du jeu par rapport au montant de porte. Comme on peut le voir dans la figure 1, la serrure 10 comprend une bande flexible 12 ayant une première extrémité 14 et une seconde extrémité 16 et une série de trous entre ces deux extrémités (dont trois sont illustrés, soit 48, 50 et 52). La serrure comprend également une première plaque de calage 18 fixée à la première extrémité de la bande flexible et une seconde plaque de calage 20 fixée à la bande souple entre ses deux extrémités. Cette seconde plaque comporte également un trou 46 aligné sur un des trous de la bande flexible. La serrure comprend également un verrou 26 dans lequel on peut enfiler un cordon 28 et qui permet de coincer celui-ci de façon amovible. Ce cordon est fixé à la première plaque ou à la première extrémité de la bande flexible. Il est passé dans les trous de la bande flexible et de la seconde plaque puis dans le verrou. Pour caler la porte en position fermée, il s'agit d'insérer la première plaque entre la rive libre de la porte et le montant de la porte, de débloquer le cordon en manoeuvrant le verrou, de tirer sur le cordon pour plier la bande flexible et amener la seconde plaque en position contre la face intérieure de la porte. Puis il s'agit de fermer le verrou pour coincer le cordon et maintenir les deux plaques de calage en position de verrouillage.
