Abstract

A spring (14) is stretched when closing the deadbolt (13) and a second element, formed of a bell (15), movable vertically, locking / unlocking the extension and withdrawal positions of the deadbolt , comprises a projection (15b) supported in the locked position, or lower, on the end of a tab of the follower (2), so that, by turning the door handle, and the follower, the bolt is unlocked frame which then retracts entirely under the pressure of the spring (14).

Description

The concept of the panic lock applies

  than any lock that can be opened in a

  tance whatever by a simple action of rotation exer-

  created on the button or handle; which means that with this quick and simple action, the lock must open even when its bolt has been extended to

  means of the key and is furthermore in the state of con-

damnation.

  At this point, it should be explained that

  tightens by locked lock a lock in which, after having put the bolt in extension (simply lock

  "closed"), a blocking sentence is established for this

  the situation which prevents the bolt from being able to be

  towed under the effect of an external thrust applied directly to this bolt; we get the situation

  lock "condemned" and, in the opening operation-

  re, the start of the action must cause the lifting of the sentence, so that the bolt can retract

when the maneuver is completed.

  The object of the present invention is a lock

  re equipped with a new and available anti-panic device

  tinct which, as we will see on reading the

  detailed description which follows, is of a design

  extremely simple and safe and efficient operation

  ce In the preferred embodiment used for explaining the object of the invention, a lock equipped with a bolt which can be closed using

  a lock cylinder, as well as a latch bolt for

  before being actuated by a handle as well as by the

rillet.

  The security of a closed door is

  turns into his worst enemy in a situation of

  braid, in which it is not only about

  get out but also do it as quickly as possible

  ble In such situations, a closed door can be the direct cause of a tragedy that would not have

  place if the door could have been opened timely.

  To deal with this problem, we imagined

  design a lock that can be opened without having to

  care of a key, so that in situations

  distress, in which panic deprives people of their ability to think in cold blood, all it takes is a simple and quick gesture consisting in turning a handle or a knob for the door to open.

  type of lock is the one designated by the expression-

"panic lock".

  The beneficial effects of panic locks

  do not prevent the necessary mechanisms involved

  a considerable complication of the mechanism, already complex in itself of a simple lock, from which it results

  that the smallness of the available space and the multiplicity

  parts and movements are problematic

  whose resolution is difficult and laborious.

  Solutions for making anti-locks

  panic that are already known are many and varied,

  while the solution according to the invention is of a con-

  new and unique concept, based on the use of small parts, simple and economical by their

  constitution, and which bring the possibility of a function-

simple and reliable operation.

  The panic lock device according to the invention responds to a new and unique design

  according to which it is planned, in functional association

  tional with the bolt of the lock, a first element

  constituted by a spring which is charged with elas-

  tick during the bolt closing operation, and

  a second element consisting of a bell

  nation / unlocking of extension and

  removal of the bolt, movable in vertical translation and mu-

  denies a projection which, in the locking position, or lower position, of the bell, is supported on

  the end of a leg formed by the follower in the-

  which mounts the handle of the lock so that,

  in the working opening rotation of this excavation

  lot, said tab presses from bottom to top against this

  protrusion, causing the consecutive rise of the

  che, up to its upper or unlocked position

  tion, in which the bolt is automatically and fully

  rement retracted, under the impulse due to the release of the elastic energy accumulated by the spring during the closing operation, so that the lock opens

  by the action of the handle alone.

  In the very frequent case, where the lock is provided, in addition to the bolt, with a latch bolt equipped with its own locking mechanism, it is provided according to

  the invention that the follower comprises a finger which, at the

  purpose of the opening rotation, carried out using the handle, automatically produces the unlocking of the latch bolt at the moment when, under the action of the tab,

  occurs the simultaneous rise of the bell which disconnects

  damn the bolt, so this latch bolt is automatic

  tick retracted by its spring and it suffices to complete the possible rotation of the handle so that the latch bolt is also retracted, causing the

  total complete opening of the lock by the single action

tion exerted on the handle.

  That is to say, as we can get

  account, the device according to the invention is exclusive-

  based on the use of a bolt load spring, a special projection presented by the bell which would in any case equip the lock to ensure the

  condemnation of the bolt and a special paw and finger-

  ment provided, presented by the nut of the handle, to ensure respectively the unlocking of the bolt and

that of the latch bolt.

  This reduced number of elements, joined to the simpli-

  cited from their configuration, makes the construction of the

  simple and economical lock; on the other hand, this im-

  furthermore, the movements are also limited to those of these few elements, which is reflected in the fact that its complete operation is simpler and, therefore, more reliable and more efficient, since the maintenance required is reduced and longevity of the mechanism

is thus improved.

  So that the unlocking of the bell can also be carried out by acting on the key, in agreement

  with normal opening and closing maneuvers

  re, this bell has at the bottom a point formed by

  inclined edges, front and rear, which, in the ma-

  opening and closing works of the bolt carried out using the key, are interposed respectively on the stroke that the eccentric of the barrel traverses while going towards the corresponding actuation notch located at the lower edge of the tail of the bolt, so that when climbing on these inclined edges, this eccentric causes the unlocking of the bell to rise,

  to allow the longitudinal movement of the bolt.

  According to another characteristic of the invention, to ensure the correct positioning of the eccentric

  barrel in its resting state, provision is made for

  install a positioner that pivots on an axis and sits

  ted by an elastic spring, this positioner having an active arm which said spring places tangentially to

  the trajectory of the eccentric in an adjacent region

  te at the desired rest position, in which the fact that the point of application of the spring force is at the maximum distance from the axis favors obtaining a

  lever arm of considerable length for multipli-

cation of the motor force.

  This last characteristic aims to avoid

  that under the effect of insufficient precision of the mechanism

  nism under the aspect of the correct angular position in which the eccentric must be at the end of a maneuver, or even under the effect of a maneuver

  imperfectly executed, it may happen that the former

  centric is on the withdrawal path of the bolt, which could result in jamming of the lock mechanism, at the time of opening, as well as under the effect of strong tremors when the bolt is suddenly retracted by the spring charge during

  the use of the panic opening function.

  It should be stressed at this point that the use of the anti-panic function is not limited in practice to

  case of a real distress situation but only at the

  milking, it is common to use this function for convenience to open the door from the inside, then to

  lock the door when you are outside.

  Other features and advantages of the

  vention will be better understood on reading the description

  tion which follows, of an exemplary embodiment and with reference to the accompanying drawings in which: Figure 1 is a general view of the inner mechanism of a lock produced according to the invention, put in the functional state of closed lock and condemned; Figure 2 is a view similar to Figure 1 but that shows the location of the open lock with the use of the panic function and when the

  handle remains turned relative to its position of re-

  pos In this figure, we also show the function of the po-

  sizer 16 which acts on the eccentric 8 a of the barrel 8 against its spring 2 a; Figure 3 is a partial view similar to the

  previous figure but which shows the function of disconnection

  damnation of the bell 15 produced by a rotation of the eccentric 8 a The position corresponds to the first turn of the barrel and the follower remains stationary; Figure 3 A is similar to Figure 3 but it represents the actuation of the latch bolt by

  the eccentric after the completion of the opening of the fishing

  born; Figure 4 is a side elevational view of the bolt; Figures 5 and 5 A are elevational views

  side (according to figure 1) and in profile which correspond

  tooth in half of a follower 2 which is formed by applying two halves (inside and outside) back to back

  which may be designed to act jointly or independently

  pending (each under the action of its own poi-

  gnea); Figures 6 and 6 A are elevational and side views of the transmission lever 7; Figures 7 and 7 A are elevational views

  from the side (as shown in Figure 1) and pro-

  bell wire 15; Figures 8 and 8 A are respectively

  side elevation views (as seen in the figure)

  re 1) and of positioner profile 16.

  In the drawings, a pre-

  embodiment of the device according to the invention, used in a lock comprising a deadbolt 13 and a half-turn bolt 1, and which can be actuated by means of a barrel 8 and a handle, the latter being mounted in the follower 2 The latch bolt 1 is

  equipped with its own locking mechanism, consisting of

  killed by the lever 5 which is placed in its locking position by a spring when the latch bolt 1 is extended and the plate 4 secured to the retractable sensor 3 is retracted The lever 5 can be placed in the unlocking position also well by the finger 2 b, during the rotation of the follower 2, than by

  the lug 7 has the transmission lever 7 when the latter

  deny rocking, transforming the tangential action of the

  barrel 8 in a half bolt retraction thrust

  turn 1 The unlocking position of this lever 5 is

  held by the fin 4 a of the plate 4 when the cap-

  retractable latch 3 is protruding, as well as by the head of the latch bolt 1 in most of its withdrawal stroke Naturally, the withdrawal of the latch bolt

  1 is also actuated by the arm 2 a of the follower 2.

  With regard to the panic device according to the invention, it can be appreciated that, when the deadbolt 13 is in extension (FIG. 1), the spring 14 is loaded elastically, its thrust being

  stopped by the conviction that paw 15 has clo-

  che 15 placed in the rear notch 13 b of the series of

  three notches which are made in the upper edge

  laughing tail 13 has bolt 13 In this situation,

  the projection 15 b of the bell 15 remains pressed on the end

  half of leg 2 c of follower 2 and, if we consider

  the position of Figure 1, in which the condemned-

  tion of the latch bolt 1 is thus closed, owing to the fact that the standing frame 11 prevents the sensor 3 from being extended, the locking lever 5 will remain with its rear end pressed on the finger 2 b of the follower 2; all this when, legally, the follower 2 is

in its rest position.

  Starting from the situation in which the fisherman

  only dormant is in extension or closed, the opening of the

  lock effected by the use of the anti

  panic is very simple As shown in the figure

  2, simply rotate the handle (or, which

  comes to the same, the follower 2) so that the direct action of the tab 2 c on the projection 15 b produces the rise

  of bell 15, which removes the conviction of the pat-

  te 15 a in the notch 13 b, so that the deadbolt

  13 is automatically pushed back to its return position

  total line through the load spring 14 At the same time, the finger 2 b acts on the lever 5 by tilting it to the unlocking position (FIG. 2) so that, after the rotation of the follower to its position

  final, withdrawal of the latch bolt 1 may occur

  re, so that we get the total opening

  of the lock by a single actuation of the handle.

  When the lock is actuated by means of the barrel 8, both when closing and when opening, the unlocking of the unlocking of the bell 15 at each turn of the key is produced (FIG. 4) by the action of the excen- plate 8 a of the barrel on the respective edges lower front 15 c or lower rear 15 d which are raised by

  this eccentric 8 has, so that the tab of condemned-

  tion 15 has abandoned the locking notch 13 c before the eccentric is applied laterally on the corresponding notch 13 c of the lower edge of the tail 13 a of the deadbolt 13, when this eccentric

  causes movement of deadbolt 13.

  During the opening of the lock

  barrel, as shown in the figure

  re 3, the vertical position of the eccentric 8 has represented

  te the maximum rise of the bell 15 which is produced when the edge of the eccentric 8 has coincides with the point formed between the lower inclined edges 15 c, 15 d; if, in this position, the spring 14 does not cause the sudden opening of the bolt 13, it is because the eccentric 8 has housed in the actuation notch 13 cy is an obstacle From this point, with the rotation of the eccentric 8 a, the bell 15 descends and its lug 15 a comes to slide (with the translation of the bolt) on the

  horizontal segment between two convection notches

  nation 13 b, until it fits in the next notch 13 b, situation which coincided with the rotation

  of the eccentric 8 a, and with the abandonment by this eccentric

  that of the actuation notch 13 c on which it exerts

it's a push.

  In the second round of the barrel 8, the eccentric 8 a performs the same maneuver, but in the other notch

actuation 13 c.

  When, using the barrel 8, one carried out

  the entire bolt removal maneuver 13, the lever

  tical 7, which moves with this barrel, reaches in its translation to the position shown in FIG. 3 A and the lower inclined edge 7 b is placed on the circular orbit of the eccentric 8 a, so that, during a new turn (the third turn) of the barrel 8, in the direction of opening, the eccentric 8 a causes

  the oscillation of lever 7 and the withdrawal of the half bolt

  turn 1, since, for its part, the lug 7 a with which this lever is provided has caused the tilting movement of the locking lever 5 All of this occurs without intervention

of the follower 2.

  As regards the positioner 16, the figures

  res 1, 3, 8 and 8 A clearly illustrate its shape and function It has a radial configuration with three arms, one of the arms being pivotally mounted on the shaft 16 a, another (the arms being biased by the spring elastic 16 c, the third arm being an active arm 16 b which is subjected to permanent pressure and which acts by its inner edge against a peripheral part of the

  circular path of the eccentric 8 a.

  The mission of positioner 16 is to make

  so that, in the closed situation, in the-

  which the deadbolt 13 is in extension (Figure 1), the eccentric 8a is not on the path of the tail 13a of the deadbolt 13 because, if this were the opening made by operating the follower 2 (anti-panic opening) could cause the lock to lock The pressure that the inner edge of the active arm 11b of the positioner exerts against the side of the eccentric 8 forces it, in the last part of its journey to "se clear "from the proximity of the tail

  13 has deadbolt 13, even if we didn't turn it-

  This is particularly important when the barrel 8 permanently contains the key (a habit which some users adopt on the inside of the door) or when the inside

  wears an actuation button, replacing a battery

  keyless This is because, in these cases, the position

  end of the eccentric 8 a (which coincides with the posi-

  key extraction) may not be suitable-

reported to the user.

  Of course, various modifications and varian-

  your can be brought by a person skilled in the art to the

  positive which has just been described by way of an unrelated example

  mitative without departing from the scope of the invention.
