Description

The invention relates to locks comprising a main bolt of the type

  U-turn, that is to say beveled and resiliently biased at the exit from the trunk

  the lock, for insertion into a keeper (posi-

  lock closing), an auxiliary bolt also resiliently urged out of the trunk, a range linked to the strike, suitable for opposing the output of the auxiliary bolt, means for exploiting the re-entry of the auxiliary bolt to ends for holding the main bolt 19 in its extended position, and controlled means actuable from one of the two sides of the lock, called

  "outside" side below, suitable for releasing the main bolt

  key of the strike, even when the auxiliary bolt is retracted.

  In the known embodiments to which the

  fan preferably, but not exclusively, applies, the means for holding the main bolt in its extended position are arranged so as to block this bolt in this

  position: the interest presented by such locks resi-

  in that it is not possible to fit the main bolt into the trunk, from the outside of the lock, simply using a thin instrument

  slid between this trunk and the strike, as long as the latch

  liaire is in its retracted position.

  With known embodiments of locks

  of the genus considered, the opening of the lock from the former

  tieur constantly requires the use of a key or other device under control such as a coding keyboard or

than a magnetic card.

  However, there are many applications for-

  which it is interesting to be able to control the opening of the lock, during certain authorization periods, by simple actuation of an external control handle, such actuation being on the contrary rendered inoperative outside said periods of authorization: periods

  authorization may be for example ini-

  held by the pressing of an electric push button by an authorized person located outside the lock's access point, but with a view to it, or by the introduction of a coded magnetic card in an appropriate reader, and the end

  such an authorization period can then be de-

  terminated by simply closing the consecutive lock

when it opens.

  This is precisely the essential aim of the invention of

allow such commands.

  For this purpose locks of the kind in question are essentially characterized according to the invention in that

  that they further comprise an auxiliary keeper solidai-

  re of the main strike and suitable for receiving the auxiliary bolt when closing the door, a stopper constituting the above range, stopper suitable for moving in the auxiliary strike between two stable positions corresponding respectively to the clearance and to the blocking of this keeper, means, preferably electric, for moving this plug from one to the other of its two stable positions and vice versa, an external control handle and a connection mechanism capable of kinematically linking this handle to the main bolt in such a way that a rotation of the handle results in a retraction of the two bolts if they have both gone out and, on the contrary, is ineffective with respect to the main bolt as long as the auxiliary bolt is in its

  retracted or only partially extended position.

  In preferred embodiments, use is made

  in addition to one and / or the other of the following provisions:

  The invention comprises, apart from these main provisions

  the, certain other provisions which are preferably used at the same time

  time and which will be more explicitly discussed below.

  In what follows, we will describe embodiments

  preferred invention according to the drawings below

  appended in a non-limiting manner, of course.

  Figures 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:

  first, in the closed state of the lock with its two bolts out, situa-

  tion which allows opening by simple actuation of the external handle

  superior; 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

return of the auxiliary bolt.

  Figure 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.

  In each case, 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 shoemaker comprising a main keeper 5 suitable for jointly receive the main bolt 3 for the purpose of "closing" the lock and an auxiliary strike

  6 suitable for receiving the auxiliary bolt 4.

  For the sake of clarity, it will be assumed in the following, when describing the lock illustrated in FIGS. 1 to 6, that the two bolts are arranged vertically one above the other and move horizontally, but it is obvious

  that the lock in question can be oriented differently.

  The main bolt 3 is of the U-turn type, that is to say

  say beveled with a flat or curved ramp and it can be the same for the auxiliary bolt 4 although this does not

  is not essential, as explained below.

  The main bolt 3 comprises a shank 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 column.

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 small column

horizontal 14 secured to the trunk.

  This auxiliary bolt 4 is constantly stressed at the

  exit from the trunk 1 by a helical spring of com-

  pressure 15 surrounding the baluster 14.

  The role of the auxiliary bolt is as follows: its position

  re-entry into the trunk automatically secures the

  cage of the main bolt in its extended position, whether the output of the latter took place before or after the re-entry of the

auxiliary bolt.

  The mechanism ensuring this blocking comprises: - a blocking finger 16 carried by a link 17 pivotally mounted about a fixed axis C linked to the boot, finger likely to be on the re-entry path of

  the tail 7 for certain angular positions of the rod

  lette say "blocking" or on the contrary out of this tra-

  jectory for other angular positions of said rod, called "unlocking", - a torsion spring 18 constantly urging the rod towards its angular locking positions, - and a bent lever 19 pivotally mounted around a

fixed axis D of the boot.

  For the extended position of the auxiliary bolt 4 (fig.l) one end of the bent lever 19 bears against a folded tab 20 of the tail 12 and the other end of this bent lever 19 bears against the link 17 so as to maintain in an unlocked position: for this purpose, the force of the spring 18 is chosen so as to be overcome by that of the spring 15.

  If, from this situation, we bring in pro-

  gressively the auxiliary bolt 4 by counteracting the effort

  antagonist of spring 15, we first observe rockers

  elements of the link 17 and of the lever 19, under the effect of the relaxation of the spring 18, and this until the angular stop of the link against a part of the lock then secured

from the trunk.

  From this moment, which intervenes for a meeting

  relatively shallow opening of the auxiliary bolt, corresponding to

  laying, for example, 1/5 of its return trip, the

  following said re-entry no longer has any consequences on the

  blocking mechanism 16-19 and the tab 20 moves away from the lever 19: most of the return of the auxiliary bolt

  therefore corresponds in this respect to a dead travel m (fig. 3).

  During the tilting indicated above of the link 17, 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 stop

  while when finger 16 is located

  above said level, the same thrust tends to return it to its unlocking positions by angular displacement upwards around the axis C. Means are provided so that the re-entry of the main bolt 3 in the trunk 1 automatically results in that auxiliary bolt 4, the beginnings of these two

  re-entries are preferably offset by a slight delay.

  These means comprise a vertically guided slide 21

  wedging between fixed pads 22, 23 and 24 secured to the trunk, the latter pad 24 serving as a journal for the

roller 8 above.

  The slider 21 is kinematically linked to the tail 7 by an angle deflection elbow 25 mounted pivoting about the axis A and having two perpendicular forks which overlap jointly, the first, a pin

  26 secured to the tail 7 and the second, a solid 27 pawn

slide of 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

  with a pin 30 secured to the tail 12.

  The game j in question makes it possible to start the meeting.

  entry of the auxiliary bolt 4 only after the main bolt

  cipal 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 retraction of the bolt 3

  is then blocked by the stop of its tail against this finger.

  To allow however to complete at the same time the returns of the two bolts 3 and 4 in the trunk, despite this delay initially taken by the auxiliary bolt 4, the latter is given smaller dimensions than the main bolt 3 and / where we impose a multiplier between the

  displacements of the two bolts, in particular by giving two

  their different to the transmission ratio of the movement

  between the slide 21 and the bolt 3 and the transfer ratio

  mission of the movement between said slide 21 and the bolt 4.

  The auxiliary bolt drive by the main bolt

  pal even allows the first to be given a non-beveled shape-

  tee insofar as, of course, this shape does not hinder the control of the re-entry of the main bolt by simple

  stop of its inclined ramp against the corresponding strike.

  Figures 1 to 3 show at 31 an external control handle cut along its operating rod

square.

  As indicated above, 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 out and the bolt

auxiliary has returned.

  To this end, 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

  coil tension spring 33, towards a re- position

  pos for which this arm abuts against the stud 23.

  By rotating the handle 31 in the opposite direction to the arrow F, the arm 32 abuts against a pin 34

of the slide 21.

  As this slide 21 is kinematically linked to the

  tail of main bolt 3, re-entry of this bolt is possible

  ble, in response to a simple rotation of the handle 31, as long as the blocking pin 16 is not located on the path

  reentry of said bolt, that is to say as long as the auxiliary bolt

  liary 4 is completely out or almost completely out.

  If on the contrary the finger 16 is in the blocking position, as a result of the retraction of the auxiliary bolt 4, the

  slide 21 is itself blocked, as is handle 31.

  In the embodiment described above, the ren-

  entry of the auxiliary bolt 4 in the lock box has the effect of putting finger 16 in its locked position

  and the handle 31 is locked in place

  ve by the stop of the tail 7 of the main bolt against this finger 16

  This stop must therefore be very solid and resistant

  te to forced attempts that may be made

  on it by subjecting the handle 31 to angular forces

intense res.

  According to a variant making it possible to eliminate any risk of forcing of this type, the re-entry of the main bolt is translated

  again possibly through the effect explained above, but on-

  all by a break in the kinematic link between the poi-

  genea 31 and the main bolt 3. There can be many such a break

  ways, two of which are shown below.

  According to the first embodiment, the slide 21 below

  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 in such a way that the mutual joining of the two slides is eliminated

  when the auxiliary bolt 4 enters the boot and reverses-

  is lying. According to the second embodiment, 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, the farthest from the handle is mounted on a

  link rod 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

clutch release and vice versa.

  The lock illustrated in Figures 1 to 6 can also

  be open regardless of the initial position-

  Auxiliary bolt 4 retracted or exited, from the

  simple rotation of an interior handle 35 (fig. 4) or of

  do external key 36 suitable for causing a pannetoû 37, for example by means of a locking assembly

of the rotating barrel type.

  To this end, the handle 35 is angularly integral therewith.

  an arm 38 angularly biased in the direction of the arrow

  che G towards a rest position for which it comes in

stop against stud 23.

  If this handle 35 is actuated in the opposite direction to the arrow G, the arm 38 abuts against a pin 40 secured to a second slide 41 (fig. 4 and 5) parallel to the slide 21 above and guided vertically by the

same studs as the latter.

  This slider 41 comprises: a heel 42 capable of interacting with the above link 17 in order to push it back into an angular unlocking position for which the finger 16 releases the re-entry of the main bolt 3,

  - and a stop (here constituted by the bottom of a

  43) suitable for coagulating with a pin 44 integral with the slide 21 so as to hang the two slides 41 and 21 one on the other as soon as the angular displacement of the handle 35 has been sufficient to place the link 17

in the unlocked position.

  In addition, 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

  abuts this slide 41 against the pad 24.

  That said, it is understood that a simple rotation of the handle 35 in the opposite direction of the arrow G allows in all cases to bring the two bolts 3 and 4 into the trunk, the necessary sliding being released from the start of this rotation by positioning

release of the link 17.

  With regard to control by key 36, we pre-

  sees a third slide 46 parallel to the two preceding

  teeth and guided vertically by the same studs as these. This third slide 46 comprises: a lug 47 capable of interacting with the bit 37,

  - And means for hanging said third coulis-

  bucket on the second slide 41 in the direction of the central

  second slide by the third and not in reverse. 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 pawns 48 and 49.

  There is also in the third slide 46 a light 51 playing the same role as the light 43 hollowed out in the second slide 41 and of the same outline as the latter.

  The three slides 21, 41 and 46 are advantageous-

  consisting of three overlapping plates with in-

terposition:

  - between the first 21 and the third 46, de rondel-

  the spacers 52 and the arm 50 (see FIG. 5), - and between the second slide 41 and the plaster or

  bottom 53 of the trunk, of spacing washers 54.

  In the illustrated embodiment, the two poi-

  gnées external 31 and internal 35 are coaxial, but they are axially separated from each other by a pellet 55 (fig. 6) mounted loose on a support linked to the

trunk 1.

  This pellet 55 advantageously constitutes the bottom

  common of two cylindrical buckets 56 and 57 open respectively

  tively towards the two sides of the lock and 'suitable for receiving respectively thickened portions, with cylindrical contour of revolution, of the two arms 32 and 38, portions themselves hollowed out by square holes 58, 59 suitable for

  join the rods of the two handles together

  nees. 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 the fig-

  re 6, two hollow pillars 60 integral with the trunk 1 and pre-

  each successively feeling an end set in the

  bottom of this chest, which it crosses, a cylindrical shoulder

  dric forming a spacer and a tubular barrel. This fat crosses itself firstly a first plate 61 crossed by one of the buckets 57, then a washer 62 of

  same thickness as the annular portion of the arm 50., which

  the portion encircles the tablet 55, then a second plate

  tine 63 crossed by the other cup 56, then a 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 horizontal and parallel to the common axis of the handles 31 and 35 as well as to the axis of the key

  36, i.e. perpendicular to the sliding direction

horizontal bolts.

  The inputs of the auxiliary bolt 4 into the trunk 1 and its outputs outside this trunk can be controlled from

anyway desirable.

  In an advantageous embodiment, these commands are ensured, when said auxiliary bolt 4 is located

  horizontally opposite the auxiliary strike 6 corres-

  laying, by pushing this bolt using a plug 66 placed in this auxiliary strike: - when the plug 66 is pressed into the bottom of the strike 6 (fig. 1), the auxiliary bolt 4 can enter it freely and therefore exit the trunk 1 as far as possible under the rebound of the spring 15, - when, on the contrary, the plug 66 occupies the keeper 6

  until it is flush with its edge (fig. 2 and 3), the latch

  liaire 4 is pushed back by this plug in its retracted position

in the trunk.

  The movement of the plug 66 is controlled

  even preferably electrically remote, but

  it could also be mechanical.

  The fact that the release of the main bolt 3 is controlled exclusively when the auxiliary bolt 4 is in its fully or almost completely out of the boot position allows to give without disadvantage to

  the interval i between the trunk and the strike a relative value

tively high.

  Following this, and whatever the mode of realization

  sation adopted, we finally have locks whose constitution and operation stand out sufficiently

* of the above.

  These locks have many advantages over

  those previously known and in particular that of

  carry an external control handle which is automatically

  only condemned when the auxiliary bolt is in

  its depressed position and which is, on the contrary, made operative

  by simply re-entering the auxiliary bolt into the cof-

lock fre.

  As it goes without saying, and as it results from elsewhere

  In addition to the above, the invention is in no way limited to those of its modes of application and embodiments which have

  been more specifically contemplated; she embraces it,

  milking, all variants, in particular: - those o, the two bolts 3 and 4 of the lock being

  still vertically superimposed, the common axis of the two poi-

  genes 31 and 35 and that of the key would be arranged horizontally

  side by side instead of being superimposed, as visi-

  ble respectively at 67 and 68 in FIG. 7, - those o the axes of the two interior 35 and exterior 31 handles would be offset transversely with respect to each other instead of being merged, those o the axes of the two handles 31 and 35 and the key would be confused, as visible in Figure 8, - those where the two main bolts 3 and auxiliary 4 would be nested one inside the other, as still visible in Figure 8, the entire mechanism then

  advantageously contained, except for the handles

  key and key device, in a cylindrical housing of revolution 69 proper itself to receive the two bolts contiguously in its portion closest to the headrest 2, - those where a key control would be provided on both sides of the lock , or on both sides,

  - those where the two external and internal handles 31

  35 would be interdependent, and then

  both associated, like the outer handle 31 above, with a locking mechanism slaved to the retraction of the bolt

  auxiliary, - those where the interior handle 35 would be arranged

  like a panic handle, constantly operating-

  nelle, - those where the exits of the main bolt 3 from the trunk 1 would be combined with the displacements of other bolts kinematically linked to said bolt 3 by appropriate linkages (linkages shown diagrammatically by the arrow T in FIG. 1), these other bolts acting with as many suitable strikes as is well known in the field of multi-point door locks,

  - those where the couiisseau activated by the solid arm

  daire of the outer handle (31) would be merged with the tail of the main bolt (3) instead of being connected to this tail by an angle gear,

  - and those where, the means of "maintaining the main bolt

  pal in its extended position ", means whose actuation is subject to the returns of the auxiliary bolt, would be arranged not so as to physically block the main bolt

  in its extended position, but simply to neutralize

  read the order for the return of this main bolt by

  simple operation of the external handle.
