Definitions

  • the present invention relates to a change device code, intended for an authorization mechanism of the movement of a control member by composition of a coded. Such a control member is frequently used for the operation of a lock.
  • Authorization mechanisms for moving a lock handle generally have a body on which are arranged several pushers. A user, when wants to operate the handle, dial a code and, when the dialed code is valid, can turn the handle to operate the lock and open the corresponding door.
  • Certain known systems include devices coding electronics that allow easy change code if needed. However, they have several disadvantages. The most important is their installation complicated because there must be an electrical connection and a power supply. In the event of a this power supply, access to the protected door can be impossible. In addition, such an installation is expensive.
  • US-A-5,058,404 relates to a mechanism in which code change is performed by access from the inner side of the door: it requires drilling the door to a specific location. This characteristic is extremely inconvenient, especially in the case of doors armored.
  • the object of the invention is to allow the change of code such mechanisms without any disassembly, simply access to elements directly accessible from the outside mechanism and access side to the pushers.
  • the invention relates to a device and a code change process which, by simple operation of the control member (handle), pushers code composition and a directly accessible device code change authorization, allow to change the mechanism code from the outside, very quickly and very easily.
  • the invention thus relates to a device and a method code change that knowing code valid and the ability to control a device code change authorization is sufficient for the valid composition can be canceled and replaced by another composition freely chosen by simple pushing of the pushers.
  • the authorization system and code change ban can be operated either by anyone who dialed the code in valid, only by certain people (for example having a particular key or code).
  • the displacement of the organ locking with respect to the slide is ensured by the operation of the control member over part of its race, through the linkage device.
  • the displacement of the locking member with respect to the slide is ensured by the operation of the change authorization body of code.
  • the travel stroke of the control member comprises a part in which the control member moves the slide, and part of resetting without moving the slide.
  • a stop member and an encoder member associated have one a projection and the other a groove.
  • the volume of displacement is an elongated space of displacement in translation
  • the connecting device transforms the displacement in rotation of the control member in a displacement in translation of the slide.
  • the locking member is movable parallel to the axis of movement of the slide, and it has discontinuities along its length giving it a rack shape.
  • each guide element has a hole formed in the guide body.
  • the coding member is a cam in two positions in one of which a projection or a groove of the coding organ is opposite a groove or a projection respectively of the corresponding device when, in any other position, there is no no correspondence between the projection and the throat.
  • the encoder member is then a movable cam in rotation about an axis parallel to the axis of movement of the slide.
  • the coding member is a cam having at least two parts of cooperation with the body of locking.
  • the code change authorization system is a key lock.
  • the authorization device for code change is another authorization mechanism for movement by dialing a code.
  • the authorization mechanism movement of a control member includes a device vested benefits.
  • the mechanism additionally includes a device for holding each stop device in a position other than its reset position.
  • resetting can be carried out at the end of the organ's travel in one of the directions of travel, and one of the blocking and passage positions of each device stop may be a reset position.
  • moving the control member is a control rotation of lock.
  • the composition and maneuvering operations are performed in a single order which depends on the achievement material of the specific movement authorization mechanism a control member.
  • FIG. 1 shows, in front elevation, a lock according to the invention.
  • This lock 10 is operated by a handle 12. It includes an authorization mechanism displacement of the handle, marked with the reference 14, this mechanism comprising pushers 16 which allow the composition of a code.
  • Two pushers 18 placed at the top of the lock allow the mechanism to be put in the free position passage and tilting to the position prohibiting free passage.
  • the function of these pushers 18 is, when the valid code was dialed with pushers 16, to make the authorization device inoperative so that the handle 12 always opens the lock.
  • Such a characteristic which is not described further in detail in this brief as it is well known to in general, allows for example to determine periods during which access to a room is free and periods during which this access is limited to people who know the code.
  • Another pusher 17 is intended to cause the ascent of all stop devices, for example when user made a mistake in ordering the code.
  • the reference 22 designates a lock with barrel, part of the lock controlled by the mechanism according to the invention.
  • Authorization mechanisms for moving a handle usually have a slide operated in translation during the operation of the handle 12 by a connecting member, when stop devices moved by the pushers have suitable positions.
  • a slide and devices stop each controlled by a pusher, include cooperating organs, one of which is shaped like a groove and the other the shape of a projection, such as, if all protrusions and all the grooves of all the devices are not opposite, the slider cannot be moved against the stop devices if although the operation of a handle is prohibited.
  • the mechanism according to the invention has characteristics analogous, but refined to allow change of code.
  • Figure 2 shows in section a cover 24 which surrounds the mechanism and guides the pushers 16.
  • the cover advantageously formed of a robust and molded metal, has walls side and top which protect the internal mechanism, and upper holes each intended for passage a button 16.
  • a body 26 of the mechanism is secured to the cover and is intended to be fixed on the support of the controlled element, for example a door provided a lock.
  • This body 26 delimits, opposite each pusher, a circular hole 28 in which can move in translation a stop device 30.
  • the device stop 30 is intended to be held in two positions stable, a raised position shown to the left of the Figure 2 and a depressed position shown to the right of the Figure 2.
  • the stop device 30 comprises a part enlarged frustoconical 32 whose upper part can hang on an orifice edge 34 of a plate of reset 35 which, when moved, allows return of all inserted stop devices to their up position.
  • Each stop device is recalled towards the position raised by a spring 36. We do not describe not this stopper retainer in one from two different positions because it is well known in the technique and only one embodiment has been shown, of many other achievements are possible.
  • each stop device has a groove 38.
  • This groove 38 which has the same position on each stop device, so has a height different depending on whether the stop device is in position high or up (left in Figure 2) or low or pressed (on the right in Figure 2).
  • the Principe ofsolutionment of the mechanism is such that each device stop does not prevent sliding (perpendicular direction in the plane of FIG. 2) of a slide when protrusions of this slide are at the level of the notch of the stop device, but prevents sliding when a projection of the slide is not opposite the notch.
  • the slide carries several organs. He understands first, coding members 40 with cam, on the basis of a member by stop device. Each encoder 40, which can rotate in this embodiment around an axis parallel to the axis of movement of the slide, has a projection 42 of shape complementary to that of the throat of the stop device.
  • the organ also includes two notches neighbors 44, one of which is intended to be in taken with an edge of a locking member 46 normally secured to the slide.
  • the latter includes several other parts, including a plate 48.
  • the operation of the handle causes a displacement in translation of the slide, forming a whole which moves as a whole and which comprises the plate 48 which carries the coding members 40, of which positioning is determined by the locking member 46, this locking member 46, and the axis of rotation of the coding organs.
  • the mobile assembly therefore forms an assembly which has laterally protrusions 42 on two levels different, and which can only be moved in translation when each projection 42 is opposite a groove 38 of the corresponding stop device.
  • the slide stroke is less than the distance longitudinal separating two neighboring pushers, and, when the handle is in the rest state, each projection 42 is adjacent to the corresponding stop device in the direction of movement of the slide and does not penetrate in the throat of the stopper, so that the operation of the stop device in one direction or the other is possible.
  • the projection 42 does not cooperate with the groove corresponding 38 that when the slide has advanced, and this only when the slide has advanced sufficiently allows the opening of the lock.
  • the code change of the authorization mechanism shown in Figure 2 would produced by removing the cover 24, by access to the lock 46 so that it can be removed or moved, for example modification of the position of each coding member 40 in function of the new code desired, then by reinserting the locking member 46. It would therefore be necessary to disassemble the lock. In the particular case considered, it would have to dismantle the door lock before you can remove the cover from the mechanism body.
  • the invention relates to a method and a device. allowing code change without any disassembly. More specifically, according to the invention, an authorization device and a code change ban allows for unbinding of the locking member 46 of the slide, so that it can slide over a limited distance such that the rib of this locking member leaves the notches of the coding organs, while the projections of the encoders are engaged with the grooves of the devices stop. In this way, when the locking member 46 released all coding bodies, stop devices, which have been brought back for example to the position raised by a reset device, i.e.
  • the locking member should have a rack shape, as shown in Figure 3.
  • the rib of the locking 46 has locking teeth 50 (rightly a tooth for two neighboring coding organs in the case considered) which are only present on the parts corresponding to the travel of the coding members during the normal running. Between these teeth 50, spaces 52 are placed opposite the notches 44 of the coding members in the code change authorization position.
  • the locking member is normally moves with the slide, as a whole, but, in the code change authorization position, the locking member is offset longitudinally and releases all coding organs whose code can then be exchange.
  • Figure 4 shows the upper part of the mechanism of figure 1 which represents the elements which allow either to secure the organ of lock and slide, or their separation.
  • the reference 48 designates the slide plate which is moved by the binding and handle.
  • Reference 46 designates the extension of the locking member.
  • Reference 20 designates the barrel lock which constitutes the authorization device and prohibition of code change. This barrel controls a bit 56 which, in the authorization position code, at the position shown in figure 4, in which it retains the end of the locking member 46.
  • the locking member which is normally driven with the slide plate 48 due to the presence of the spring 54, is then retained by the bit 56 so that it slides in relation to slide 48. From in this way, the teeth 50 of the locking member are separate notches from the coding members 40 which are driven by the slide plate 48.
  • the rearming plate 35 is operated, if although all of the stop devices 30 go back into their pusher and, simultaneously, the coding members 40, which are released from the teeth 50, are recalled by springs incorporated into each encoder, in the position in which the projections 42 have risen. As soon as the rearming plate 35 is reset, the operator can press the pushers 16 corresponding to the new combination, then release the handle which then slides the rib 46 of the locking member in the notches of the members coders. Just rotate the bit 56 of the latch so that the lock can work with the new code.
  • a lock provided a mechanism for authorizing the movement of a handle having a code change device controlled by an authorization and prohibition system consisting a barrel lock.
  • an authorization and prohibition system consisting a barrel lock.
  • the slide constitutes a rotary member driven in rotation by the handle, and the stops and pushers are arranged in total or partial circle around a common axis of rotation.
  • An authorization and prohibition device has been described code change including a barrel lock, that is to say controlled by a key.
  • This device can be of any type.
  • the essential characteristic of the invention is that when a locking member has unlocked the encoders, these can be placed in position corresponding to a new desired code, before new locking, by operation of devices directly accessible from outside the mechanism, without no disassembly or tools, and without the use of a source any electricity.
  • the mechanism according to the invention can be mounted on any lock, without modification of the strike or sleeping from the door nor from the lock, and having a low width to be able to be mounted on a glass door with narrow frame.
  • All the elements of the mechanism can be metallic, but those skilled in the art know that certain elements, for example complex in shape or not requiring great robustness, can be made up of other materials, for example plastic.
  • the mechanism according to the invention optionally gives the vested benefits function, previously described with reference to the pushers 16.
  • this function can be obtained by using a device which prevents the slide from describing the second part of its race (reset).
  • This device can simply include a projection and a clearance, respectively placed on the body or cover and on the slide and intended for cooperate to limit the slide stroke to its first part.
  • An advantageous characteristic of the mechanism according to the invention, when used with a lock, is that it can be reversible, that is to say that it can be controlled by a handle (control member) rotating either right or left.
