The finger 48 is repositioned and snaps into the eye 15 of the head 13 of the hasp 4 when the bolt spring 32 returns to its initial position and pushes the bolt throwing 31. The key 8 is inserted by a first translational movement according to a plane perpendicular to the plane of the stack 22, in the first insertion slot 47 formed in the stack 22, then in the central slot 78 of the slide 37; until the fingerprints 20 of the key 8 come into contact with the conical ends 96 of the pivots 40 which project into the central slot 78. When the key 8 is out of or just introduced into the central slot 78, the pivots 40 are subjected to the action of the piston springs 42 by means of the second stops 41 which are interposed between the pistons springs 42 and the pivots 40, and partially project into the central slot 78, the second stops 41 then being arranged astride in the ducts 85 and in the receiving holes 89, thus preventing the movement of the slideway 37. The first translational movement of the key 8 is continued so as to move the pistons formed by the pivots 40 and the second stops 41, to against the pistons springs 42, in a plane substantially parallel to the plane of the stack 22. The pivots 40 push the second stops 41 until the latter are completely in the holes 89 and out of the ducts 85, while the pivots remain completely in the ducts 85, thereby allowing the slide 37 to move in the casing 10 under the action of a second translational movement of the key 8 (succeeding immediately and extending the first translation movement), always in a plane perpendicular to the plane of the stack 22. The slide 37 thus released is moved in the cavity 45 of the housing 10, in a plane substantially perpendicular to the plane of the stack 22, against sliding springs 20 by the second translational movement of the key 8. The notch 83 of the slide 37 comes into contact with the right face 112 of a non-return tooth 111 projecting from a side 108 of the star wheel 34 of so as to drive the latter in rotation, here up to a quarter turn, around the pin 105 of the stop support 34. Figures 24 and 25 illustrate the translation of the slide 37 and the rotation of the wheel oilée 34, here in a so-called intermediate configuration, where the star wheel 33 is turned an eighth of a turn and where the pistons are split since the pivots 40 which are in the slideway 37 are no longer opposite the second stops 41. in other words, the ducts 85 of the slideway 37 are no longer opposite the receiving holes 89 of the pistons support 38. The slideway 37 is displaced until it comes into contact with the second bottom wall 58 of the stack 22, where the groove 84 of the slide 37 is housed in the groove 88 of the stack 22. During the rotation of the star wheel 33, the side 108 of the latter which is opposite the second end 99 of the second stop 35 pushes the latter against the stop spring 36; then this stop spring 36 expands and returns the first stop 35 against another side 108 of the star wheel 33 once its rotation quarter turn. The rotation of the starwheel 33 causes the movement of its locking finger 115 from its first position where it leaves the bolt 31 free to its second position where one of the parts of the locking finger 115 comes opposite and in the immediate vicinity, even in contact with the bearing face 77 of the throwing bolt 31; so as to immobilize the latter in its predetermined position where its locking finger 48 is snapped into the eye 15 of the head 13 of the hasp 5. The bag 2 is thus closed. The key 8 is removed from the slots 78 and 47 respectively of the slideway 37 and the bearing 22, by a translation movement (in a direction opposite to that of the translational movement for the insertion of the key 8). The slide 37 is thus returned to its initial position by the action of the slide springs 39 and, during the movement of the slide 37, the notch 83 comes into contact with the ramp face 113 of the non-return tooth 111 which protrudes from the side 108 opposite the side wall 79 of the slide 37 and moves the star wheel 33. During the rotation of the star wheel 33, the side 108 of the latter which is opposite the second end 99 of the second stop 35 pushes the latter against the stop spring 36; then this stop spring 36 expands and returns the first stop 35 against the same side 108 of the star wheel 33 once the notch 83 of the slide 37 is no longer in contact with the ramp face 113 of the anti-tooth. back 111.

The profile of the ramp face 113 of the anti-return tooth 111 allows the slide 37 not to return the star wheel 33 in its first position, and thus allows the latter to remain in its second position where it blocks the bolt 31. In addition, the pistons formed pivots 40 and second stops 41 also return to the initial position. The unlocking process comprises the steps below.

The star wheel 33 is here in its second position in which its locking finger 115 is opposite the bearing face 77 of the throwing bolt 31. As for the locking, the key 8 is inserted by a first translational movement according to a plane perpendicular to the plane of the stack 22, in the first insertion slot 47 formed in the stack 22, then in the central slot 78 of the slide 37; until the fingerprints 20 of the key 8 come into contact with the conical ends 96 of the pivots 40 which project into the central slot 78.

The first translational movement of the key 8 is continued so as to move the pistons formed by the pivots 40 and the second stops 41, against the pistons springs 42, in a plane substantially parallel to the plane of the stack 22. The pivots 40 push the second stops 41 until the latter are completely in the receiving holes 89 and out of the ducts 85, while the pivots 40 remain completely in the ducts 85, thus allowing the slide 37 to move in the casing 10 under the action of a second translational movement of the key 8 (succeeding immediately and extending the first translational movement), always in a plane perpendicular to the plane of the stack 22. The slide 37 thus released is moved into the cavity 45 the housing 10, in a plane substantially perpendicular to the plane of the stack 22, against the slide springs 20 by the second translational movement of the key 8.

The notch 83 of the slideway 37 comes into contact with the right face 112 of a non-return tooth 111 projecting from one side 108 of the star wheel 34 so as to drive the latter in rotation, here up to a quarter of turn, around the journal 105 of the stop support 34. The slide 37 is moved to contact the second bottom wall 58 of the stack 22, where the groove 84 of the slide 37 is housed in the groove 88 of the stack 22 .

During the rotation of the star wheel 33, the side 108 of the latter which is opposite the second end 99 of the second stop 35 pushes the latter against the stop spring 36; then this stop spring 36 expands and returns the first stop 35 against another side 108 of the star wheel 33 once its rotation quarter turn. The rotation of the star wheel 33 causes the displacement of its locking finger 115 from its second position where it blocks the bolt throwing 31 to its first position where the locking pin 115 is at a distance from the bearing face 77 of the throwing bolt 31 and leave him free.

The key 8 is removed from the slots 78 and 47 respectively of the slideway 37 and the bearing 22, by a translation movement (in a direction opposite to that of the translational movement for the insertion of the key 8). The slide 37 is thus returned to its initial position by the action of the slide springs 39 and, during the movement of the slide 37, the notch 83 comes into contact with the ramp face 113 of the non-return tooth 111 which protrudes from the side 108 opposite the side wall 79 of the slide 37 and moves the star wheel 33. During the rotation of the star wheel 33, the side 108 of the latter which is opposite the second end 99 of the second stop 35 pushes the latter against the stop spring 36; then this stop spring 36 expands and returns the first stop 35 against the same side 108 of the star wheel 33 once the notch 83 of the slide 37 is no longer in contact with the ramp face 113 of the anti-tooth. back 111. The profile of the ramp face 113 of the anti-return tooth 111 allows the slide 37 not to return the star wheel 33 in its second position, and thus allows the latter to remain in its first position where it leaves free the bolt throwing 31. In addition, the pistons formed pivots 40 and second stops 41 also return to the initial position.

The actuator button 7 is actuated in a translation movement substantially parallel to the plane of the stack 22, so as to move in translation the bolt throwing 31 against the spring 32 which is compressed by the action of the button 7 fixed by its rod 29 in the opening 71 formed on the first leg 70 of the latch 31. The movement of the latching bolt 31 causes the removal of its locking finger 48 of the eye 15 of the head 13 of the hasp 5, the latter being thus released from the housing 10 and ejected by the hasp spring 43. The button 7 is released and the latch bolt 31 returns to its initial position under the action of the bolt spring 32 which returns. The bag 2 is thus open. Figures 29 to 31 illustrate a key 108 introduced into a control system 130 according to an alternative embodiment of the invention.

The control system 130 is provided with a slide 137 movably mounted in a lock housing (not shown) and formed by a block 135 having a generally parallelepipedal shape (also called mobile part). The block 135 comprises a front flange 140, a rear flange 145 and a plurality of safety elements 150 sandwiched between the front and rear flanges 140 and 145. The front and rear flanges 140 and 145 and the security elements are fixed together by fixing screws 136 so as to form the block 135. The front flange 140 comprises a drive notch 183 projecting from a peripheral edge of the front flange 140 and configured to drive a latch bolt locking member ( not shown). The front flange 140 has an insertion slot 142 configured to receive the key 108 and a notch 143 formed in the peripheral edge of the front flange 140, opposite the drive notch 183.

The front flange 140 further comprises two through holes 141 for the passage of the fixing screws 136 and two blind holes 144 configured to receive slide springs (not shown). The rear flange 145 has an outer face 146 in which are formed two through holes 147 for the passage of the fixing screws 136 and two through holes 186 for the passage of the slide springs. The rear flange 145 has a notch 148 formed in a peripheral edge of the rear flange 145.

Each security element 150 is provided with a frame 151 having a peripheral slot 152 (part of which is masked and thus represented in dashed line), two through-holes 153 for the passage of the fixing screws 136 and two through-holes 154 for the passage of the slide springs.

Each security element 150 is further provided with a recess 155 in the frame 151 and having a circle shape; an insertion slot 156 configured to receive the key 108 and a tooth 170 projecting into the recess 155. Each security element 150 comprises a movable member 157 housed in the recess 155 and mounted to move relative to the frame 151 The movable member 157 has a central window 158 for security and reception of the key 108, central window 158 whose edges 159 are slightly bevelled, and a safety groove 171 configured to be superimposed on the peripheral slot 152. of the frame 151.

The safety groove 171 is formed in two parts, namely a first notch 172 formed in the movable member 157 and defining a recess 173, and a second notch 174 formed in the recess 173. The movable member 157 has in addition to a cutout 175 here arranged opposite the safety groove 171 and defining a first wall 176 configured to bear against the tooth 170 of the frame 151, and a second wall 177 opposite the first wall 176. Each element safety device 150 further comprises a safety spring 178 disposed in a space of the recess 155 left by the cutout 175 formed in the movable member 157, which safety spring 178 is interposed between and abutting against the tooth 170 and the second wall 177. The notches 142 and 148 as well as the peripheral slot 152 and the safety groove 171 respectively formed in the front and rear flanges 140 and 145 and in the elbows. Safety elements 150 form a longitudinal groove 180 in the block 135. The control system 130 is further provided with a support 160 fixedly mounted in the lock housing (also called a fixed part) and formed by a substantially parallelepipedic body 161. provided with a positioning step 162 in the housing. The carrier has a plurality of locking teeth 163 projecting from the body 161, in a direction opposite to the direction in which the step 162 extends, and which are configured to be inserted into the longitudinal groove 180 of the block 135. key 108 is out of the slideway 137, the movable members 157 of the security elements 150 are each in a rest position (FIG. 31) where the peripheral slots 152 are at least partially closed by portions adjacent to the safety grooves 171 and more precisely here by a portion of the recess 173, so as to form obstacles in the groove 180 of the block 135 of the slide 137. This rest position is provided by the safety spring 178 of each security element 150, which rotates the respective movable member 157 so that the first wall 176 is in contact or in the immediate vicinity of the tooth 170. The obstacles are substantially entangled with the teeth of the support 160 so that these teeth 160 prevent the translational movement of the slide 137.

When the key 8 is received and translated into the slide 137, the key 8 is inserted into the insertion slots 142 and 156 respectively of the front flange 140 and the security elements 150 and in the central security windows 158 of the organs movable 157 of these security elements 150, which at least partially align with the insertion slots 156; and simultaneously rotates the safety grooves 171 until the latter have their respective second notch 174 opposite and superimposed on the peripheral slots 152. This thus clears the groove 180 of the obstacles and allows the movement of the slide 137 in the lock housing, under the action of the translational movement of the key 8. In non-illustrated variants: - the key is not flat but has rather other forms, it is for example round ; - the key is only imprinted on one of these faces rather than on both sides; - The lock housing is not generally prismatic shape but rather of parallelepiped shape; - The first and / or second and / or the third screw can be replaced by other fasteners, for example rivets; - The lock housing is devoid of dummy button; the pivots do not have a conical but rather pyramidal or beveled end; - The lock has a control system having here three pistons formed of pivots and second stops and a key having three indentations on each of these faces but more generally, the lock may comprise at least one and preferably a plurality of pistons formed of a pivot and a first stop and at least one and preferably a plurality of impressions on the key; it being understood that each predetermined pair of cavity depth and piston stroke forms a combination of the lock; and / or - the mechanism is devoid of a rotatably mounted star wheel but is rather provided with a locking member more generally configured to establish a connection between the slide and the launching bolt, by movement (s) of translation and / or of rotation of this locking member. It is recalled more generally that the invention is not limited to the examples described and shown.
