Dans l'exemple illustré en
En
Chaque butée mécanique 109 est mobile dans l'évidement 108 qui lui est associé de sorte que lorsque la butée mécanique 109 atteint une extrémité de l'évidement 108, l'écartement ou le rapprochement des montants 11 est limité. Les deux butées mécaniques ont un mouvement dépendant de l'écartement ou du rapprochement des montants 11. Lorsqu'une butée mécanique est à une extrémité d'un évidement 108 l'autre butée mécanique 109 est à l'extrémité opposée de l'autre évidement 108.Each
Comme illustré également en
La troisième portion 104a de la deuxième coque du premier ensemble et la troisième portion 105a de la première coque du deuxième ensemble comprennent chacune deux ouvertures 107, 110 configurées chacune pour coopérer avec une butée élastique 106 de sorte que lorsque ladite butée élastique 106 fait saillie dans les ouvertures 107, 110 qui lui sont associées, la position des montants 11 est verrouillée.The
Les ouvertures 107 de la troisième portion 104a de la deuxième coque 104 du premier ensemble sont positionnées en regard l'une de l'autre par rapport à l'axe de rotation Y-Y autour duquel sont montés le premier ensemble et le deuxième ensemble.The
Les ouvertures 110 de la troisième portion 105a de la première coque 105 du deuxième ensemble sont positionnées en regard l'une de l'autre par rapport à l'axe de rotation Y-Y autour duquel sont montés le premier ensemble et le deuxième ensemble et coïncident avec les ouvertures 107 de la troisième portion 104a de la deuxième coque 104 du premier ensemble.The
