Description

Embedded lock ''

Technical area

The present invention relates to a built-in lock of the type comprising a chute-shaped housing closed by a cover and receiving the entire actuation and locking mechanism of the lock, this mechanism consisting of an actuation device , a control linkage, movable longitudinally in the housing, and at least one bolt or similar locking device, disposed away from the actuating device and capable of projecting from the housing in the closed position of the lock, the linkage ensuring the connection between the assemblies constituted by the actuating device and the locking device. PRIOR ART A device of this type is known in particular for producing multi-point locks actuated by a mechanical device, and is generally designed to be applied projecting from the inside of the door.

In such a device, the lock drive mechanism consists of a complete assembly, operating independently of the housing and inserted into it, the linkage simply ensuring the connection between the actuating members projecting from the mechanism. drive and locking devices.

Also known are lock mechanisms intended to be embedded in the door, generally in the door jamb; this amount is either a wooden piece, or even a rectangular metal profile in the case of a metal door. In this case, they are complete sets: complete lock with bolt integrated in a box, or, in the case of multi-point locks, lock integrated in a box and diverter, which are embedded in the door, generally by mortising at the location of the lock and of the deflectors, these elements then being connected by a linkage introduced longitudinal in the door jamb.

When an electric lock is used, for obvious security reasons, such a lock is generally installed comprising a mechanical device for opening the lock in the event of a power failure. In this case we are required, due to the system of embedding the lock in a mortise formed in the upright (generally a metal profile in the case of an armored door), to embed in the said mortise a lock complete comprising, in a single built-in box, the electric lock, the mechanical opening system and the bolt or locking device. Statement of the invention

The present invention applies in general to built-in electric locks for doors which include metal uprights. It applies more particularly to locks for such doors which include metal uprights as parts of the frame either of the opening or of the door frame. An objective of the present invention is to rationalize the manufacture, both of embedded locks and of doors comprising such locks.

This objective is achieved by providing that, in a lock of the type described in the introductory part of claim 1, the lock is a multi-point electric lock, comprising at least two locking devices spaced from one another, the linkage connects directly between them, the locking devices, integral with the housing, and slides in the housing, being guided on the latter by means of said locking devices, the actuating device is an electric motor, integral with the housing, and a transmission mechanism ensures the transmission of movement between the actuating device and the linkage, motor and receiver elements of said transmission mechanism being directly fixed respectively on the motor output shaft and on the linkage.

Such an arrangement, in which the various elements of the lock mechanism are distributed along the linkage and are directly accessible over the entire housing, makes it possible not only to simplify the mounting of the lock and of its possible accessories, but also to '' easily and effectively include, in the form of mechanisms acting at the level of the linkage and distributed along the latter, a series of additional elements allowing, in a simple and inexpensive manner, the production of reliable devices increasing the number of functions that can be performed by the lock.

Such advantageous embodiments of the lock of the invention are the subject of the dependent claims.

In addition, the fact that the housing of the lock constitutes the amount of the door greatly simplifies the integration of the lock with the door during the manufacture of the latter, thus greatly reducing the cost of mounting the lock on the door. . Brief description of the drawings

In the various embodiments described in this patent, the same reference numbers denote the same elements.

Referring to the simplified embodiment of FIG 1, a lock according to the invention comprises a housing 1 in the form of a chute, of which two locking devices 2, 2 ′ are integral spaced from one another, in l 'occurrence of the deflectors controlling the exit of the bolts 3. A rod 4 extends between the deviators 2, 2' and slides in the housing 1 on which it is guided through the so-called 2, 2 'deviators. An electric motor 5, integral with the housing 1 on which it is mounted, actuates the linkage 4 via a transmission mechanism 6 constituted, in the example shown, by a rack and pinion system. A cover, not shown, which is not part of the invention, is provided for closing the chute by any known means.

The advantage of such an arrangement is on the one hand to constitute the linkage as a receiving element of the movement initiated by the actuating device, and thus make it possible to multiply along the linkage the number of different actuating devices while more easily decoupling the linkage from these various actuation devices, and on the other hand to rationalize and thus simplify the manufacture and assembly of the various actuation devices, which must not be integrated with one another. This arrangement also makes it possible, as will be seen below, to significantly and simply and reliably increase the number of functions that can be performed by the lock.

A first preferred embodiment of the invention is illustrated in FIG. 4.

According to this embodiment, the lock of the invention comprises, just as in the embodiment of FIG. 1, a housing 1 in the form of a chute secured to two deviators 2, 2 ′ controlling the movement of bolts 3 between a position protruding as shown in Figure 4, corresponding to the closing of the lock, and a recessed position as shown in Figure 1, corresponding to the opening of the lock. A linkage 4 slides in the housing 1 by pressing on the deflectors 2, 2 'by which it is guided in the said housing 1. An electric motor 5 drives the linkage via a transmission 6'.

In addition, an auxiliary mechanical device actuation 7 is provided to act in a location of the linkage separate from the transmission 6 ', in order to allow the opening of the lock by the action of a key in the event of power failure. According to the preferred embodiment of the invention illustrated in FIG. 4, the auxiliary mechanical actuation device 7 also includes a locking device 8 for the linkage in the closed position of the lock. In the absence of such a locking device, in fact, any action exerted on the linkage 4 in the direction of opening the lock would effectively open the latter. In addition, this auxiliary mechanical actuating device 7 is provided for controlling the linkage 4 only in the direction of one opening.

The various elements mentioned above, and in particular the transmission 6 ′, the auxiliary mechanical actuation device 7 and the locking device 8 of the linkage, will be described in more detail below in conjunction with FIGS. 2 and 3 respectively , 5, and 6.

Figures 2 and 3 show a preferred embodiment of a transmission 6 'between the electric motor 5 and the linkage 4, particularly suitable for cooperation with an auxiliary mechanical actuation device 7 of the linkage 4. Indeed, in general, use is made of electric motors 5 having a high speed of rotation, which therefore require the use of a speed reducer 9. In such cases, driving the motor from the output shaft 9 'of the speed reducer 9, drive which, in the absence of an appropriate device, occurs when the linkage is actuated towards the open position by the auxiliary mechanical actuating device, requires a large torque, and therefore a significant effort on the key actuating the auxiliary mechanical actuation device.

In this perspective, the 6 'transmission provides a disengaging of the motor in the event of a power failure. In the embodiment illustrated in the patent, this declutching is carried out in the following manner. The transmission 6 'consists on the one hand of a motor pinion 10 arranged at the end of the output shaft 9' of the speed reducer 9, and on the other hand of a toothed belt 11 winding on two pulleys 12, 12 'which pivot on an axis integral with the linkage 4, the cooperation of the pinion 10 with the toothed belt 11 being ensured by tension rollers 10', 10 ". The pulley 12 'is integral with a pinion 13 coming into engagement with a pinion 14 controlled by an electromagnetic clutch 15 fixedly mounted on the linkage 4.

When the electromagnetic clutch 15 is supplied with current, and therefore the electrical control of the lock can operate normally, the pinion 14 is immobilized in rotation, thereby blocking the pulley 12 ', and therefore the winding of the toothed belt 11 on the pulleys 12, 12 '. The toothed belt 11 then remains stationary relative to the linkage 4. In this case, the rotation of the motor 5 causes the toothed belt 11 to move relative to the pinion 10, without winding the toothed belt 11 on the pulleys 12, 12 ', and therefore the displacement of the linkage 4 relative to the pinion 10. When the power supply to the lock, and therefore to the electromagnetic clutch, is interrupted, the pinion 14 can pivot freely. Thereby a displacement of the linkage 4 relative to the pinion 10 causes the toothed belt 11 to be wound on the pulleys 12, 12 ′ without causing the pinion to pivot. The actuation of the linkage by the auxiliary mechanical device actuation is thereby facilitated.

Fig. 5 schematically shows the operation of the essential parts of an auxiliary mechanical device for actuating the linkage as shown at 7 in FIG. 4. This device essentially comprises, as a movable element, a control arm 16 whose face lower 16 'is intended to cooperate with a projection 17 formed on the linkage 4 to act on said linkage only in the direction of opening of the lock.

The control arm 16 moves on a support 18, integral with the housing 1, via buttonholes 19, 19 ′ formed in said control arm, buttonholes which cooperate with studs 20, 20 ′ secured to the support 18. The support 18 is arranged in the housing 1 so that this movement of the arm on the support takes place, at least substantially, in a movement parallel to the direction of movement of the linkage.

The control arm 16 comprises two series of notches, respectively a series of locking notches 21 and a series of actuation notches 22.

The locking notches 21 cooperate successively with a lug 23 carried by a lever 24 oscillating on the support and constantly biased in the direction of the arrow 25 by a spring, not shown, tending to bring the lug 23 in cooperation with a notch blocking 21. In the example shown, the lever 24 oscillates around the stud 20.

The actuation notches 22 cooperate with the bolt 26 of a lock cylinder 27, in the field of action of which the bolt 26 also penetrates the lever 24. The rotation of the bolt therefore causes on the one hand the pivoting of the lever 24 and from its lug 23 to a position away from the locking notches 21, and on the other hand the displacement, over a distance of one notch, of the actuating arm 16 by action of the bolt 26 on the wall of the notch 'corresponding actuation 22. Continued rotation of the bolt until it clears the actuation notch 22 allows the lever 24 to return in the direction of the arrow 25, for engagement of the lug 23 in the following locking notch 21. The stroke total of the actuating arm 16, and therefore the number of turns of the bolt, is thus provided to ensure, by an action on the projection 17, a displacement of the linkage 4 corresponding to a total opening of the door.

According to a preferred embodiment of this auxiliary mechanical actuation device 7, the control arm 16 consists of two plates of identical profile, parallel, assembled at a spacing, and the lever 24 carrying the locking pin 23 is arranged between the plates constituting the control arm 16.

According to the embodiment of the invention illustrated in FIG. 4, the electrical control of the door, as well as the auxiliary mechanical actuation device, control a locking device 8 of the linkage. As shown in fig. 6, this locking device consists of a stop 28 formed on the linkage and a latch 29 oscillating on the housing 1. More particularly, in the example shown, the latch 29 oscillates on the support 18 secured to the housing 1 The latch 29 is constantly biased in the direction of arrow 30 by a spring, not shown, towards a position of engagement with the stop 28. This engagement, as illustrated in FIG. 6, is ensured in the closed position of the lock. . Thus, any movement of the rod 4 allowing a retraction of the bolts 3 is prevented as long as the unlocking of the rod 4 is not ensured.

The electrical control of the latch 29 is provided by an electromagnet 31, the plunger of which instantly brings the latch 29 away from the stop 28, prior to actuation of the electric motor 5.

In the event of a power failure, and control of the opening device by the auxiliary mechanical actuating device, the control of the latch 29 is ensured by the cooperation of a ramp 32, formed in the latch 29, and of a finger 33 carried to the upper part 34 of the actuating arm 16. The descent of the actuating arm, in the first part of its travel, causes the descent of the finger 33 along the ramp 32, and thus the pivoting of the latch 29 to its position 29 'illustrated in dotted lines. It is only after this pivoting that the underside 16 ′ of the actuating arm 16 comes into contact with the projection 17 on the linkage 4. The continuation of the stroke of the actuating arm 16 ensures the lowering of the linkage 4 and the opening of the lock , the finger 33 continuing its downhill course along the ramp 32.

According to this embodiment, once the lock has been opened by the auxiliary mechanical actuating device 7, the latter is brought back, by suitable action on the key actuating the cylinder 27, in the high closed position such that 'illustrated in solid lines in fig. 4. When the current returns, this allows the electric motor 5 to activate the linkage 4 until the lock is in the closed position, the latch 29 then being pushed back by the stop 28 against the action of the spring. (arrow 30), until it rebounds under said stop 28 and is in the locked position. This movement of the latch 29 is also obtained on each closure by the electrical control of the door, following an opening by this same electrical control.

A particularly preferred embodiment of the invention is finally illustrated schematically in FIG. 7.

This embodiment comprises, in addition to the elements already described in connection with FIG. 4, a quarter-turn lock 35, the lance 36 of which cooperates with an electric strike 37. This electric strike 37 is, of course, normally controlled by the control electric door opening.

The mechanical actuating device 38 of the quarter-turn lock 35 is integral with a lever 39 coming in cooperation with the linkage 4 via a buttonhole 40. Furthermore, an L-shaped element 41 slides on the linkage 4 by the cooperation of studs 42, 42 ', integral with the linkage, with buttonholes 43, 43' formed in the large arm 44 of said L-shaped element 41. This L-shaped element 41 constitutes, by its small arm 45, the projection on the linkage intended to cooperate with the arm 16 of the auxiliary mechanical actuating device 7.

The L-shaped element 41 is arranged on the linkage, considered in the closed position, so that, when it rests by the upper end of its buttonholes 43, 43 'on the studs 42, 42' of the linkage, the end of its large arm 44 comes into contact with the lever 39 in the rest position, corresponding to the rest position of the actuation mechanism 38 of the quarter-turn lock 35. The length of the buttonholes 43, 43 'corresponds substantially to the length of the linkage stroke (4) between the closed position and the open position of the lock.

Furthermore, in this same closed position of the lock, the lever 39 is arranged in the buttonhole 40 so that the length of buttonhole 40 disposed above said lever 39 also corresponds substantially to the length of the travel of the linkage. between the closed position and the open position of the lock. The buttonhole 40 is further extended by an additional length, the role of which will be explained below, under the lever 39.

The lever 39 comprises an arm 46 suitably connected - in the example diagrammatically shown in FIG. 7, via a cable 47 and pulleys 48, 48 '- to the latch 29 of the locking device 8 of the linkage 4.

The various operating modes of this lock, from the closed position to the open position, are schematically illustrated respectively in FIGS. 9 a, b, c; 10 a, b, c and 11 a, b, c, and are discussed below.

In general, in these various figures only are shown, schematically, the elements involved in the operating mode considered. In each of these figures are shown respectively a housing 1, containing the lock and constituting the amount of the door leaf, and the amount correspondent 49 of the frame. In the cooperation of the sash with the frame, only the tossing 36 of the quarter turn lock in the sash, and the electric strike 37 in the frame, are shown. The position of the bolts, not shown in these figures, in their corresponding cavity of the frame, is of course a function, as described above, of the position of the linkage 4.

Each of FIGS. 9a, 10a, 11a shows the lock in the closed position, that is to say the linkage 4 in the high position, the bolts protruding into their cavity of the frame and the electric strike 37 being locked in rotation (which is schematically represented in the drawing by the action of an electromagnet 50).

Figs 9a, 9b, 9c illustrate the operation of the electrical control elements of the lock, that is to say its normal operation.

In FIG. 9a, the linkage 4 is in the high position, its locking is ensured by the engagement of the latch 29 under the stop 28, the keeper 37 is blocked and cooperates with the thrower 36, the bolts are engaged in their respective cavities of the standing 49 and the clutch 15 is energized, ensuring the blocking of the pinion 14 and, via the pinion 13, the blocking of the pulley 12 ′ and therefore of the toothed belt 11. In FIG. 9b, the control of door opening has just been given. The electromagnet 31 is energized and attracts the latch 29 towards it, ensuring the unlocking of the linkage 4. The motor 5 is energized while the clutch 15 also remains energized. The rotation of the pinion 10 at the outlet of the motor shaft, combined with the locking of the toothed belt 11, causes the displacement of the linkage 4 towards the open position of the lock, and the progressive withdrawal of the bolts from their cavities. According to a preferred embodiment of the invention, the control of the electric strike 37 is timed to maintain the strike 37 in the closed position as long as the total withdrawal of the bolts from their cavities is not realized. This arrangement avoids that, by an untimely thrust exerted by the user on the door at the time of opening, the bolts are trapped in their cavities during their withdrawal movement, causing an overload of the motor 5, or possibly even a total blocking of the opening movement. Keeping the electric strike 37 in the closed state, cooperating with the thrower 36, makes it possible to unload the bolts from any effort resulting from such untimely thrust, and therefore in all cases ensures correct operation of the lock until in the open position.

Once the opening position of the lock is reached (fig 9c), the toothed belt 11, locked on the pulleys 12, 12 ', has moved under the action of the motor 5 by a distance d, driving the linkage 4 in its downward movement. Simultaneously the electric strike 37 is released, its pivoting allowing the release of the lance 36 and therefore the opening of the door. Note that during this downward movement of the linkage 4 no action was exerted either on the L-shaped element 41 or on the lever 39 actuating the quarter-turn lock 35. This downward movement of the linkage 4 only resulted in a displacement of the studs 42, 42 'in the respective buttonholes 43, 43' and of the lever 39 relative to its buttonhole 40.

When the lock returns to the closed position (not shown), the door is first closed, and the thrower 36 bounces past the keeper 37 again locked. The linkage then rises to the closed position under the action of the motor 5 on the toothed belt 11 still locked. This movement continues until the stop 28 passes beyond the latch 29, which rebounds under the stop 28 under the action of its spring (arrow 30 in fig 6), and the linkage 4 comes to a standstill. closed position, locked.

The door can be opened in the event of a power failure using the auxiliary mechanical actuation device as illustrated in figs 10 a, b and c.

In the closed position of the door (fig. 10 a), the linkage 4 is in the high position for closing the lock, the actuating arm 16 of the auxiliary mechanical actuating device (see figs 5 and 6) is also in high position, the latch 29 is engaged under the stop 28 of the linkage locking device, and the finger 33 at the upper part of the actuating arm 16 cooperates with the upper part of the ramp 32 formed in the latch 29.

The lowering of a first notch of the actuating arm 16 by an action of the key in the lock 27 causing the rotation of a turn of the bolt 26 (see fig 5) causes the actuating arm 16 to descend into its support from a distance d ₁ , and concomitantly the descent of the finger 33 along the ramp 32, and therefore the pivoting of the latch 29 away from the stop 28. The linkage 4 is thus unlocked, while the actuating arm 16 is brought into contact with the small arm 45 of the L-shaped element 41. This is illustrated in FIG. 10 b.

An additional lowering of the actuating arm 16 exerts a push on the small arm 45 of the L-shaped element 41. This push is transmitted on the one hand to the linkage 4 by the end of the buttonholes 43, 43 'pushing on the studs 42, 42 ′ of the linkage, and on the other hand to the actuation lever 39 of the quarter-turn lock by the end of the arm 44. This lowering movement of the actuation arm 16 is continued until that the linkage is lowered to the open position, and that simultaneously the pivoting of the lever has caused the erasing of the lance (fig 10 c). The door can then open.

Note, as said previously in connection with the description of figs 2 and 3, that in the absence of current the clutch 15 (not shown in figs 10) is released, and therefore the linkage 4 can move without duty drive the motor, which reduces the force to be exerted on the actuating arm 16.

Once the door is open, the actuating arm 16 is brought back to the high position which, on the one hand, releases the latch 29 in rotation, and on the other hand releases the arm 45 from the action of the actuating arm 16, and allows the return to normal position of the lever 39, and therefore the return of the lance in the closed position. This step is not shown in the drawing. Note that throughout the various steps of Fig 10, the keeper 37 remained locked. Therefore, when the actuating arm 16 has been completely raised following a suitable action on the auxiliary mechanical actuating device 7, the door can be closed. It will be kept closed, even in the absence of current, by rebounding the lance 36 beyond the strike 37. When the current returns, suitable detectors, not shown, will detect the state of the linkage in the position of opening and the motor 5 will be actuated to bring it into the closed position.

Finally, as shown in figs 11a, b and c, use can also be made of the quarter turn lock (35 in fig 7) to cause the door to open.

In the closed position of the lock (fig 11 a), the linkage 4 is in the high closed position, the latch 29 cooperates with the stop 28 to ensure the locking of the linkage, and the lever 39 for actuating the quarter lock turn is in the rest position, the lance 36 projecting from the lock to cooperate with the electric strike 37 locked in rotation.

A first action on the actuating device 38 of the quarter-turn lock causes the lever 39 and its arm 46 to pivot into the position illustrated in FIG. 11 b. In this position, the lever 39 comes into contact with the bottom of the buttonhole 40, while the lever 46 exerts traction on the cable 47, causing the latch 29 to be released from the position for locking the linkage 4, which can thus move towards the open position. This first pivoting of the lever 39 also leads to a first withdrawal of the lance 36. Continued action on the actuating device 38 in the same direction causes an additional rotation of the lever 39. The end of the latter being in contact of the linkage 4, in the bottom of the buttonhole 40, drives said linkage 4 to the open position, while the complete launching of the thrower is also carried out. The door can thus be opened very quickly.

The actuating device 38 is for example actuated by a "panic bar", under the effect of a thrust exerted on said bar. Preferably this bar is automatically returned to the rest position when the thrust ceases, which allows the return of the lance 36 projecting from the lock. The door can then close while being kept closed at least by the cooperation of the thrower and the keeper. If, in the circumstances which led to the use of the panic bar, the current has been maintained, there is nothing to prevent the door from being fully locked again, under the action of the electric controls, once the return of the door in the closed position observed by appropriate detectors. When necessary, this makes it possible to avoid, once the premises have been evacuated, to close them again, possibly automatically by an appropriate device, and to keep them securely closed against any malicious intrusion.

Various means exist to regulate the use of such a "panic bar". There is thus a reliable and extremely rapid means of causing, when necessary, the opening of a door closed by a multi-point electric lock.

All the devices described above are made from simple elements, which can generally be obtained by cutting from sheet metal and bending, which makes their manufacture inexpensive. Their design also allows their realization in modular form, to allow flexible adaptation of manufacturing and assembly to different dimensions of lock.

According to a particularly preferred embodiment of the invention, the housing 1 of the lock also constitutes an upright of the metal door, which makes it possible to further rationalize the manufacture of the door and the mounting of the lock in said door, and therefore reduce production costs accordingly.

It goes without saying of course that the housing 1 can constitute an upright, both of the opening and of the door frame.
