Definitions

  • the invention relates to locks comprising a main bolt of the half-turn type, that is to say beveled and resiliently biased at the exit from the locker, for the purpose of introduction into a keeper (closed position of the lock), an auxiliary bolt also resiliently biased at the exit from the trunk, a range linked to the strike, suitable for opposing the exit of the auxiliary bolt, means for exploiting the re-entry of the auxiliary bolt for blocking purposes of the main bolt in its extended position, and controlled means operable from one of the two sides of the lock, called the "outside" side below, suitable for returning the main bolt to the boot even when the auxiliary bolt is retracted.
  • opening the lock from the outside constantly requires the use of a key or other device under control such as a coding keyboard or a magnetic card.
  • each of the authorization periods in question can for example be initiated by pressing a simple electric push button by an authorized person located in a room inaccessible to the users concerned, but in a place from this room from where she can see and identify these users, or by the introduction, by such a user, of a magnetic card coded in an appropriate reader connected to the lock, and the end of such a period authorization can then be determined by simply closing the lock following its opening.
  • the locks of the type in question are essentially characterized according to the invention in that they also comprise an auxiliary strike secured to the main strike and suitable for receiving the auxiliary bolt when the door is closed, a constituent plug.
  • plug suitable for moving in the auxiliary strike between two stable positions corresponding respectively to the release and the plugging of this strike means, preferably electric, to move this plug from one to the other from its two stable positions and vice versa, an external control handle and a connecting mechanism capable of kinematically linking this handle to the main bolt so that an actuation of the handle results in a retraction of the two bolts if they have come out both and on the contrary is inoperative vis-à-vis the main bolt as long as the auxiliary bolt is in its retracted position or s only partially out.
  • the holding mechanism comprises a blocking stop carried by a link which is permanently elastically urged towards an angular position for which this stop is on the re-entry path of the main bolt, this rod being mounted so as to be constantly urged in the opposite direction from the previous, towards a position authorizing the re-entry of the main bolt, by the spring which biases the auxiliary bolt at the outlet, and the connection mechanism interposed between the outer handle and the bolts comprises an arm angularly integral with the handle and a slide actuable by this arm and linked to the main bolt,
  • the rod carrying the blocking stop is actuated by the spring which biases the auxiliary bolt at the outlet by means of a lug secured to this auxiliary bolt and of a lever bearing on the one hand against this rod constantly and on the other hand against this tab only when the auxiliary bolt is completely extended or almost completely removed from the trunk,
  • the holding mechanism is arranged so as to break the continuity of the connecting mechanism when the auxiliary bolt is retracted
  • the lock comprises, in addition to the above external control handle, an internal control handle and these two control handles are coaxial and separated axially from each other by an intermediate pad mounted crazy on a support secured to the lock safe, tablet preferably constituting the common bottom of two buckets open to the two sides of the lock,
  • a lock with two handles comprising, in the manner defined above, a connecting rod carrying a locking stop and a slide, further comprises an arm angularly integral with the interior handle and a crew actuable by this arm , a crew comprising on the one hand a heel capable of interacting with the link so as to push the stopper back into its unlocked position, that is to say outside the path of re-entry of the main bolt and on the other hand a range suitable for interacting with a range of the slider for the purpose of hooking said crew on this slider at least as soon as the heel has reached its position corresponding to the release of the main bolt,
  • a lock comprising, as defined above, a connecting rod carrying a blocking stop and a slide, further comprises a rotary bit mechanism controlled by a key and an intermediate mechanism itself comprising a tab suitable for being driven by the bit , first means linked to this tab and suitable for pushing the locking stop in its unlocking position and second means for connecting said tab to the slide at least as soon as the first means have released the main bolt.
  • the invention includes, apart from these main provisions, certain other provisions which are preferably used at the same time and which will be more explicitly discussed below.
  • FIGS. 1 to 3, of these drawings show a portion of a lock established according to the invention, cover removed, in three distinct situations corresponding respectively: the first, in the closed state of the lock with its two bolts extended, situation which allows opening by simple actuation of the external handle; the second, in the open state of said lock; and the third, in its closed state with blocking of the external handle due to the retraction of the auxiliary bolt.
  • FIG. 4 shows other portions of the same lock.
  • Figures 5 and 6 are sections of said lock respectively according to V-V and VI-VI, Figure 1.
  • Figures 7 and 8 show respectively in side view and in perspective view two variants of locks also established according to the invention.
  • the lock comprises, on the one hand, a trunk 1 secured to a headrest 2 crossed by a main bolt 3 and by an auxiliary bolt 4 and, on the other hand, a housing comprising a main keeper 5 suitable for receiving contiguously the main bolt 3 for the purpose of "closing" the lock and an auxiliary strike 6 suitable for receiving the auxiliary bolt 4.
  • the main bolt 3 is of the half-turn type, that is to say beveled with a flat or curved ramp and it can be the same for the auxiliary bolt 4 although this is not essential, as specified below.
  • the main bolt 3 comprises a tail 7 guided horizontally between two idle rollers 8 and 9, the axes A and B of which are linked to the boot and it is constantly stressed at the outlet from the boot 1 by a helical compression spring 10 surrounding a horizontal baluster 11 secured to the trunk.
  • the auxiliary bolt 4 comprises a tail 12 terminated by a folded fork 13 and it is guided horizontally by overlapping, by this fork, of a horizontal column 14 secured to the trunk.
  • This auxiliary bolt 4 is constantly stressed at the outlet from the trunk 1 by a helical compression spring 15 surrounding the baluster 14.
  • auxiliary bolt its position retracted into the boot automatically ensures the locking of the main bolt in its extended position, whether the output of the latter has occurred before or after the retraction of the auxiliary bolt.
  • the locking finger 7 crosses vertically downwards the level of the axis C of this link, which allows it to effectively play its role of horizontal blocking: in fact, when finger 16 is below this level, the horizontal thrust exerted to the right on this finger 16 tends to apply the rod 17 against its end-of-travel stop whereas, when finger 16 is above said level, the same thrust tends to return it to its release positions by angular displacement upwards around the C axis.
  • Means are provided so that the re-entry of the main bolt 3 into the boot 1 automatically results in that of the auxiliary bolt 4, the beginnings of these two re-entries preferably being offset by a slight delay.
  • These means include a slide 21 guided vertically between fixed studs 22, 23 and 24 secured to the trunk, this derneir stud 24 serving as a journal for the roller 8 above.
  • the slider 21 is kinematically linked to the tail 7 by an angle return bend 25 mounted pivoting about the axis A and having two forks perpendicular to each other which overlap jointly, the first, a pin 26 secured to the tail 7 and the second, a pin 27 secured to the slide 21.
  • This slide further comprises a pin 28 suitable for coagulating with a quarter-circle sector 29 mounted idly around the axis B and suitable for coagulating itself with a clearance j with a pin 30 secured to the tail 12.
  • the game j in question makes it possible to start the reentry of the auxiliary bolt 4 only after the main bolt 3 has traveled a sufficient reentry stroke so that the end of its tail 7 has exceeded the level of the locking finger 16: this delay prevents the re-entry of the bolt 3 from being blocked by the stop of its tail against this finger.
  • FIGS 1 to 3 show at 31 an external control handle cut along its square operating rod.
  • this handle is connected to the two bolts in such a way that its simple rotation allows the main bolt 3 to be returned to the boot when the auxiliary bolt 4 is released at the same time as this main bolt and, on the contrary such a command is prevented when the main bolt is extended and the auxiliary bolt is retracted.
  • the main bolt is controlled from this handle 31 by means of the slide 21.
  • the handle 31 is angularly integral with an arm 32 angularly biased in the direction of the arrow F, by a helical tension spring 33, towards a rest position for which this arm abuts against the stud 23.
  • the re-entry of the auxiliary bolt 4 in the trunk of the lock has the effect of putting the finger 16 in its locking position and the locking of the handle 31 is ultimately ensured by the stop of the tail 7 of the main bolt against this finger 16.
  • this stop is very solid and withstands the forcing attempts which may be exerted on it by subjecting the handle 31 to intense angular forces.
  • the slide 21 above is split into two slides placed one against the other. These two slides can be joined together by a mobile pin which is guided, parallel to the axes A, B, C and D, in appropriate holes in the slides and which is resiliently biased against a ramp secured to the lever 19. This ramp is drawn of so that the mutual solidarity of the two slides is deleted when the auxiliary bolt 4 enters the boot and vice versa.
  • a rack on the bolt tail 7 or on the slide 21 there is provided on the one hand a rack on the bolt tail 7 or on the slide 21 and on the other hand a gear train in mutual engagement between the handle 31 and this rack.
  • the pinion, of this train, furthest from the handle is mounted on a second link similar to the link 17 above, and this second link is resiliently biased towards an angular position for which the pinion considered engages with the rack.
  • the tilting of the lever 19 above, due to the return of the auxiliary bolt 4 are then used to move the second link in the direction of disengagement and vice versa.
  • the lock illustrated in Figures 1 to 6 can also be opened, regardless of the position initially retracted or extended from the auxiliary bolt 4, from the simple rotation of an interior handle 35 (fig. 4) or a key outer 36 suitable for driving a bit 37, for example by means of a locking assembly of the rotating barrel type.
  • the handle 35 is angularly secured to an arm 38 angularly biased in the direction of the arrow G towards a rest position for which it abuts against the stud 23.
  • a torsion spring 45 bears against the slide 41 so as to constantly urge it in the direction which separates the heel 42 from the link 17, which puts this slide 41 into abutment against the stud 24.
  • a third slide 46 is provided parallel to the previous two and guided vertically by the same studs as the latter.
  • These means consist of two pins 48 and 49 secured respectively to the second slide 41 and the third slide 46 and by an arm 50 mounted idly around the axis of the handle 35 and extending contiguously between the two pins 48 and 49.
  • the two outer 31 and inner 35 handles are coaxial, but they are separated axially from each other by a pad 55 (FIG. 6) mounted loosely on a support linked to the trunk 1.
  • This pellet 55 advantageously constitutes the common bottom of two cylindrical cups 56 and 57 open respectively towards the two sides of the lock and suitable for receiving respectively thickened portions, with cylindrical outline of revolution, of the two arms 32 and 38, portions themselves hollowed out by square holes 58.59 suitable for receiving the rods of the two handles concerned in a joint manner.
  • the support of the assembly formed by the pellet 55 and by the two cylindrical cups 56 and 57 which extend it comprises, in the embodiment illustrated in Figure 6, two hollow pillars 60 integral with the trunk 1 and each successively having one end set in the bottom of this box, which it crosses, a cylindrical shoulder forming a spacer and a tubular barrel.
  • This barrel itself contiguously crosses a first plate 61 crossed by one of the buckets 57, then a washer 62 of the same thickness as the annular portion of the arm 50, which portion encircles the pellet 55, then a second plate 63 traversed by the another cup 56, then a spacer ring 64 and finally the lid 65 of the trunk.
  • the axes A, B, C, D and the axes of the studs 22 and 23 and the pillars 60 are all hodzontal and parallel to the common axis of the handles 31 and 35 as well as to the axis of the key 36, that is ie perpendicular to the direction of horizontal sliding of the bolts.
  • the inputs of the auxiliary bolt 4 into the trunk 1 and its outputs out of this trunk can be controlled in any desirable manner.
  • the movement of the plug 66 is itself controlled electrically from a distance, but it could also be mechanical.
