- the barrel comprises for each ball 35 a depression 37 in which the ball is housed in the retracted position, in the open position of the lock.
- the balls 35 are pushed by the bottom face of the depressions and then by a shallower portion 38 or the peripheral face of the barrel, in the holes 36 outwards to their position represented.
- the lock is then in its locking position. Any removal of the balls towards the inside of the tube 33 is impossible because they are in abutment against the peripheral face of the barrel.
- the outer tube 33 of the lock is passed, with the locking balls 35 in their retracted position, through a perpendicular through hole 39 in the lever 26 and a through hole 41 in the sole 15 of the striker.
- the end which comprises the locking balls 35 also passes through a through hole 42 in the wall of the frame structure 2.
- the lock installation movement ends when the head 31 abuts against the end 43 of the branch 19 of the U-shaped part of the striker. This end comprises, in the example shown, a rounded recess complementary to the circular shape of the tube 33 of the lock, and in the form of a segment of a cap 44 complementary to the spherical head 31.

- a forced cut in such circumstances would cause a deformation of the outer tube 33 and / or the barrel rod 38, so that these two elements are then secured in rotation so that any rotation of the barrel in the tube to cause the removal of logs in their homes is excluded.
- the figure 6 illustrates well the inaccessibility to the tube 33 because the end of the branch 19 of the keeper matches the shapes of the tube and the head 31.
- the invention also excludes any attempt, after a possible removal of the head, to push the rod 33, with its barrel 34, towards the inside of the frame structure, by providing inside thereof a hood 45 which is fixed on the inner face of the wall 46 of the support structure and caps the free end 47 of the rod, as seen in the figures. This cap is opposed to any movement towards the inside of the tube 33.
- the abutment effect can also be achieved by fixing a piece of sheet metal 48 on the internal face facing the through hole 42.
- FIGS. Figures 8 and 9 Another possibility of locking the bolt 6 in the latch 7 by means of a lock as described above, is shown in FIGS. Figures 8 and 9 .

L'invention sera décrite ci-après, à titre d'exemple, dans son application à un agencement du type crémone monté sur la partie arrière d'un camion. Plus précisément, l'agencement comporte une tringle qui est montée verticale et rotative sur le vantail et porte à chaque extrémité un pêne qui s'engage dans une gâche montée en haut et en bas sur la structure d'encadrement du vantail. La tringle est commandée en rotation par un dispositif de commande qui est monté sur le vantail.The invention will be described hereinafter, by way of example, in its application to a cremone type arrangement mounted on the rear part of a truck. More specifically, the arrangement comprises a rod which is mounted vertically and rotatably on the leaf and carries at each end a bolt which engages in a striker mounted at the top and bottom on the framing structure of the leaf. The rod is rotated by a control device which is mounted on the leaf.
La
La figure illustre, toujours schématiquement, en 11 un joint d'étanchéité qui est disposé entre la face de tranche 12 du vantail 3 et la face en regard 13 de la structure d'encadrement 1.The figure illustrates, always schematically, at 11 a seal which is disposed between the
En se référant aux figures on décrit ci-après plus en détail le dispositif de gâche et pêne 1. Ce dispositif comporte l'organe formant la gâche qui comprend essentiellement une partie de semelle 15 pourvue à chacune de ses extrémités d'un trou 16 de passage d'une vis de fixation de la gâche sur la structure de support fixe 2. A une extrémité, à côté du trou 16, fait saillie une partie 18 en forme d'un L dont la branche libre 19 et la branche 20 solidaires de la semelle forment avec celle-ci un U pourvu d'une paroi interne médiane en forme d'une voile 21 de guidage du pêne, comme il sera expliqué ci-après. La gâche comporte au niveau de son autre extrémité un plot 22 perpendiculaire, d'une hauteur inférieure à la hauteur, au-dessus de la semelle, de l'extrémité de la branche inclinée libre 19.Referring to the figures, the latch device and
Le pêne 6 solidaire en rotation, par l'intermédiaire d'un embout d'axe 24, de la tringle de la crémone est réalisé sous forme d'un levier 26 qui fait saillie perpendiculairement de l'axe de l'embout. L'extrémité libre 27 du levier présente dans son plan perpendiculaire à la semelle le profil d'un V dont la partie de pointe est arrondie de façon à pouvoir glisser sur la face interne du U de la gâche. Cette extrémité 27 présente une découpe 28 en forme d'un V dans laquelle s'engage l'arête de guidage de la voile 21.The
Le pêne présente, diamétralement opposé au levier 26, un évidement arrondi 29 de forme complémentaire à la forme du plot 22 de la gâche de façon que ce plot puisse s'engager dans cet engagement et servir de moyen de guidage.The bolt has, diametrically opposed to the
Les dimensions des parties de la gâche et du pêne sont choisies de telle façon que lors de la rotation de la tringle et donc de l'embout d'axe 24, l'extrémité 27 du levier glisse sur la partie en U et la voile 21 de la gâche, ce qui provoque tout d'abord le glissement de l'évidement arrondi 29 le long du plot 22 en direction de la flèche F, et ensuite le désengagement du pêne 6 de la gâche 7.The dimensions of the parts of the striker and the bolt are chosen in such a way that during the rotation of the rod and therefore of the
Conformément à l'invention, le pêne 6 est verrouillable dans sa position engagée dans la gâche 7, lorsque le vantail 3 est fermé. Le dispositif de verrouillage 9, dans le mode de réalisation représenté aux
Cette serrure comporte à l'autre extrémité de la structure coaxiale du tube 33 et de la tige 34 des organes de verrouillage 35, qui sont engagés dans des perçages 36 dans le tube 33 dont l'ouverture vers l'extérieur présente un diamètre inférieur au diamètre des billes, et mobiles entre une position escamotée et une position dans laquelle elles font saillie, partiellement, de la face extérieure cylindrique du tube 33. Le déplacement des billes se fait sous l'effet de la rotation de l'organe de barillet 34 dont la face extérieure présente un profil approprié comme l'illustrent les
Selon le premier mode de réalisation, pour verrouiller le pêne dans la gâche, on fait passer le tube extérieur 33 de la serrure, avec les billes 35 de verrouillage dans leur position escamotée, à travers un trou de passage perpendiculaire 39 dans le levier 26 et un trou de passage 41 dans la semelle 15 de la gâche. L'extrémité qui comporte les billes de verrouillage 35 passe également à travers un trou traversant 42 dans la paroi de la structure d'encadrement 2. Le mouvement de mis en place de la serrure prend fin lorsque la tête 31 vient en butée contre l'extrémité 43 de la branche 19 de la partie en U de la gâche. Cette extrémité comporte, dans l'exemple représenté, un évidement arrondi complémentaire à la forme circulaire du tube 33 de la serrure, et en forme d'un segment d'une calotte 44 complémentaire à la tête sphérique 31. Dans la position finale de la mise en place, la partie de l'extrémité du tube 33 qui comporte des billes 35, est située de l'autre côté de la semelle de support, par rapport à la tête 31, ou de la face arrière de la structure. Pour verrouiller alors le pêne dans la gâche 7, il suffit de tourner la clé jusqu'à ce que les billes 35 se trouvent dans leur position partiellement en saillie du tube. Bien entendu le diamètre du trou 41 de la semelle 15 de la gâche et du trou 42 dans le support doit être tel que, dans la position partiellement sortie, les billes viennent en prise derrière le trou respectif pour qu'un retrait du tube soit impossible.According to the first embodiment, to lock the bolt in the striker, the
L'invention prévoit également des moyens qui rendent la serrure de verrouillage inviolable dans sa position fermée. Tout d'abord la configuration de l'ensemble formé par la gâche et le pêne et la tête 31 de la serrure est tel qu'un accès au tube 33, par exemple dans l'intention de le couper, à l'aide d'un outil approprié, soit impossible sinon tellement difficile pour que l'opération d'une telle coupure exigerait un délai de temps trop important. De toute manière, une coupure forcée, dans de telles circonstances provoqueraient une déformation du tube extérieur 33 et/ou de la tige de barillet 38, de façon que ces deux éléments se trouvent alors solidarisés en rotation si bien que toute rotation du barillet dans le tube pour provoquer le retrait des billes dans leurs logements soit exclue. La
L'invention exclue également toute tentative, après un enlèvement éventuel de la tête, de pousser la tige 33, avec son barillet 34, vers l'intérieur de la structure d'encadrement, en prévoyant à l'intérieur de celui-ci un capot 45 qui est fixé sur la face interne de la paroi 46 de la structure de support et coiffe l'extrémité libre 47 de la tige, comme on le voit sur les figures. Ce capot s'oppose à tout mouvement vers l'intérieur du tube 33. L'effet de butée peut également être réalisé en fixant une pièce de tôle 48 sur la face interne en face du trou de passage 42.The invention also excludes any attempt, after a possible removal of the head, to push the
Une autre possibilité de verrouillage du pêne 6 dans la gâche 7 à l'aide d'une serrure telle que décrit ci-avant, est montrée aux
Ce mode de réalisation présente l'avantage d'être applicable aux dispositifs de gâche et pêne existants dépourvus des trous de passage nécessaires dans le premier mode de réalisation.This embodiment has the advantage of being applicable to existing striker and bolt devices without the passage holes required in the first embodiment.
La
En effet on constate que l'extrémité 43 de la branche 19 de la gâche est configurée de faces à coiffer l'extrémité de la tige 51, ce qui rend la tige inaccessible de l'extérieur et empêche toute action tendant à pousser de la tige 51 de l'extérieur ou l'arracher.Indeed it is found that the
