Definitions

  • the present invention relates to timed locks and more particularly to locks, the operation of which may be hampered during predetermined time intervals, the duration of which may be fixed by one or more timers.
  • Such locks are often referred to by the English term "time lock" and are used especially in protected enclosures such as safes and vaults of bank branches to prevent any operation of the door, for example, during bank closing hours.
  • the lock control box containing in particular the timer and the locking members of the lock mechanism is preferably mounted on the inside of the door. It is therefore desirable, for safety reasons, to avoid any electrical connection between the door and the door frame which surrounds it and that is why timed locks of this type most often include one or more mechanical timers capable of operate without an electrical source, i.e. using only spring energy.
  • Such a mechanical timer described, for example, in patent FR-A-2,435,584 generally includes a spring clock mechanism and regulator, the spring of which is wound up more or less to fix the variable duration of the countdown. of the timer.
  • the members coupled to the spring to allow reassembly are generally provided with a dial and an index which make the chosen duration visible to the user. Once the adjustment operation is complete, the spring drives the clock mechanism until the chosen duration has elapsed.
  • the locking members of the lock linkage can only be released by applying a certain amount of energy which must come from the mechanical timer itself and more precisely from its spring.
  • the spring has already lost a very significant part of its energy and will therefore find it difficult to overcome all the forces which are necessary for the unlocking of the lock.
  • the spring can be calculated without problems so that its amount of residual energy can still be sufficient, it is not the same for the precise instant of release which, on the contrary, is uncertain, and all the more more than the timers preferably have a maximum setting time of 144 hours.
  • the accuracy of the release instant is low and can easily vary from 30 to 60 minutes, if the maximum period of the timer is chosen.
  • the object of the invention is to provide a timed lock devoid of the drawbacks just mentioned.
  • a timed lock comprising a blocking member capable of hindering the operation of the lock during a timing invertle fixed by at least one mechanical timer, this timer comprising a spring power source, coupled by through a gear train to a governor, characterized in that the timer comprises a second governor and switching means capable of inserting into said train selectively either the first or the second governor to modify the running speed of said timer.
  • the switching means can be actuated by a control member integral with one of the moving parts of the timer mechanism, and operating the switching on the second regulator when its position corresponds to the end of the time interval. fixed.
  • the invention also makes it possible to modify the running of the timer manually either fleetingly or permanently during a whole time interval in order to be able to quickly correct a setting which has been poorly made or to be able to choose from another range of intervals. time delay, by a change of scale.
  • the timer may be provided with a display disc carrying two scales, one for a range of long intervals and the other for a range of short intervals. The latter can then be chosen with a precision much better than that of a timer whose only range of intervals has a significant maximum value, of 144 h for example.
  • the timed lock comprises a housing 1 closed by a transparent cover 2 which forms the front wall of the assembly.
  • the housing is intended to be mounted on a vault door, safe or the like, provided with a conventional lock mechanism, preferably with a combination, of which only FIG. 1 to 4 shows 'stop 3 forming part of the linkage of the lock.
  • This bar 3 can slide in a passage 4 formed in the housing 1 provided that this passage is not obstructed for the purpose of blocking by a slide 5 preventing actuation of the lock in the direction of opening.
  • a slide 5 guided in the housing 1 can obstruct the movement of the stop bar 3 by placing itself across the passage 4, thus preventing the opening of the lock (this opening corresponds in FIGS. 1 and 3 to a movement to the left of the bar 3).
  • the actual mechanism of the lock can be produced in any known manner so that a detailed description is superfluous here.
  • the slide 5 which is mounted approximately in the middle of the housing 1 has a guide hole 6 in which are arranged a spring 7 and a pusher 8 on which a pallet 9 can act articulated mounted in the housing 1 around an axis 10 .
  • the pallet 9 is in the form of an actuating lever having a control end 9a which opens into a window 11 formed in the cover 2 so as to be accessible from the front of the device. It also includes a locking spout 12 which cooperates with a transmission plate 13 slidably mounted in the housing 1 behind the cover 2.
  • the transmission plate 13 has a notch 14 traversed by the control end 9a of the actuating lever 9. In one of the corners of this notch is provided a stop nose 15 which cooperates with the locking spout 12 for fixing the position of the transmission plate 13 when the lock is in its configuration for preventing opening.
  • the transmission plate 13 is continuously urged to occupy this position thanks to the presence of a spring 16 which is engaged in a cutout 17 of the plate and which bears on the inner wall of the housing 1.
  • the transmission plate 13 also comprises several actuating fingers 18a, 18b and 18c by means of which it can be pushed back against the action of the spring 16 to cause the lock to pass from its configuration for prohibiting opening ( Figures 3 and 4) to its opening authorization position ( Figures 1 and 2).
  • the timed lock also includes several timers 19a, 19b and 19c, all identical cooperating respectively with the actuating fingers 18a, 18b and 18c and mounted fixed in the housing 1.
  • timers here three
  • the timer has two mounting flanges 20a, 20b ( Figures 5 and 6) secured to each other by means of pillars 21.
  • the shaft 23 of this barrel crosses the flanges 20a and 20b and ends on the front side of the timer by a winding square 23a intended to receive a winding key 24 ( Figures 2 and 4).
  • a pinion 25 is wedged on the shaft 23.
  • the front flange 20b carries on its front face a tenon 26 on which is rotatably an indicator wheel 27 carrying a graduation 28 ( Figures 1 and 3). The latter cooperates with an index 29 placed behind a magnifying glass 30.
  • the graduation 28 is here calibrated in hours and extends over a range of 144 h for example.
  • the wheel 27 is held on the lug 26 using a ring 31 and a screw 32 (FIG. 5) and has a toothing which meshes with the pinion 25.
  • the shaft 23 of the barrel 22 carries a wheel 33 for driving a gear train 34 which leads to an exhaust regulator 35 of the conventional type.
  • the train 34 comprises four mobiles 36 to 39.
  • the first mobile 36 carries a wheel 40 cooperating with a winding pawl 41.
  • the second, third and fourth mobiles 37 to 39 are multiplying members which transmit energy to the regulator 35.
  • the mobiles 37 and 38 each have a wheel and a pinion while the mobile 39 is of a particular construction which is will now examine with reference to Figures 7 to 9.
  • the mobile 39 has an axis 42 pivoting in the flanges 20a and 20b and carrying a pinion 43 which meshes with the wheel 38a of the mobile 38.
  • the axis 42 is integral in rotation with the cage 44 of a differential mechanism 45.
  • This cage presents the general form part of a stirrup with two lateral branches 44a, 44b and an intermediate branch 44c which ends in a development 44d surrounding the axis 42 and receiving a locking screw 46 which makes it integral.
  • Each lateral branch 44a, 44b is pierced with a hole 44e coaxial with the axis 42 to allow passage to a barrel 47, 48 of a secondary mobile 49, on the one hand, and of a regulating member 50, of somewhere else.
  • These guns 47 and 48 are mounted with free rotation on the axis 42.
  • the secondary mobile 49 comprises a wheel 51 which is engaged with the exhaust mobile 52 of the regulator 35, as well as a wheel 53 placed at the opposite end of the barrel 47 and constituting a planetary wheel of the differential mechanism 45.
  • This wheel planetary meshes with a satellite pinion 54 of this mechanism mounted for rotation in the cage 44.
  • the regulating member 50 comprises a winged disc 55 cooperating with a planetary wheel 56. These two elements are integral with the barrel 48.
  • the planetary wheel 56 meshes with a satellite pinion 57 rotatably mounted in the cage 44.
  • the indicator wheel 27 carries a control pin 58 which is intended to cooperate with a lever 59 pivotally mounted at 60 on the front flange 20b behind the disc 27 and in a plane parallel to this. flaccid.
  • the lever 59 has a bent shape and has two branches, one of which defines a lateral cam surface 59a cooperating with the control lug 58 as well as a bearing surface 59b for a return spring 61 which is also in support against the flange 20b.
  • the other branch of the lever carries at its free end a blocking finger 62 which passes through an opening 63 provided in the flange 20b and which is intended to act on the wing disc 55 to, if necessary, block it in rotation .
  • a stop lug 64 is further provided on the outer face of the flange 20b in order to stop the timer when it reaches the end of the race, the stop lug 64 cooperating for this purpose with the control lug 58.
  • the indicator wheel 27 carries on its front face another control lug 65 which is intended to cooperate with the corresponding actuating finger 18a, 18b or 18c of the transmission plate 13.
  • the lock is in the configuration shown in Figures 1 and 2.
  • the lock can be actuated normally to allow access to the protected enclosure and the closing thereof.
  • this closing must be prolonged, for example due to the absence of service personnel, the responsible person in charge will actuate the lock so that there is now an opening ban until a timeout interval to display is displayed. has elapsed, that is to say until the staff return, the next morning for example.
  • the attendant In order to close the door and jam the coding system for the lock, the attendant must then act on the pallet 9 by lowering it, then set the three timers 19a to 19c for the appropriate time interval.
  • the lowering of the pallet causes a slight lifting of the slide 5, the tensioning of the spring 7 and allows the movement of the transmission plate 13 to the left.
  • the plate 13 can only move to the left when the three timers 19a to 19c have been set and their control lug 65 has moved away from the corresponding finger 18a to 18c.
  • the instant of release of the lock corresponds to that determined by the timer in which the winged disc is released first. If the setting is made carefully, the disks of the three timers can be released almost at the same time.
  • the mobile 39 in which the differential 45 is incorporated forms switching means which modify the running speed of the timer by "plugging in” the train thereof sometimes on the regulator 35, sometimes on the regulator 50.
  • control of these switching means is automatic and governed by one of the movable members (in this case the disc 27) of the timer.
  • FIGS. 11 and 12 relate to a variant of the invention in which the increase in walking speed can also be carried out by the user himself and more precisely using the key 24.
  • the lever 59 has an extension 66 whose surface 67 opposite the flange 20b is cut obliquely so as to form a cam surface. Furthermore, a button 68 is driven into the flange 20b and it maintains an elastic strip 69 whose free end carries a wedge 70 intended to come to bear against the surface 67 to push the lever 59 by rotating it in the same sense that the control lug 58 does at the end of the timer stroke.
  • the bending of the elastic strip 69 thus urging the wedge 70 can be obtained by pushing the key 24 axially on the square 23a towards the flange 20b. As soon as the key is released, the strip returns to its initial position and the lever 59 again blocks the winged disc 55.
  • the regulator 50 can be produced using a winged disc as described above to offer a certain resistance to its rotation.
  • a winged disc as described above to offer a certain resistance to its rotation.
  • the regulator 50 can also be replaced by an exhaust regulator 71 (FIG. 13) cooperating with a wheel 72 wedged on the barrel 48 of the differential 45.
  • a regulator can be constructed conventionally like the first regulator 35, however having a different frequency.
  • it is possible to selectively impose two different running speeds on the timer for example in order to be able to choose a time interval situated as desired in two different ranges of intervals, one going from 0 to 12 hours and the other from 0 to 144 hours, for example.
