ES2498892A2 - Automatic panic locks having a number of solutions are thereby known, but when these known solutions are subjected to the increasingly higher demands to be standardized and to be granted a recognized efficiency classification (being referred to as security doors, for example), they are subjected to resistance testing of the components under the successive repetition of operating cycles which at times reach up to 200.000 maneuvers, where the known solutions accumulate wear and clearances which prevent them from obtaining the quality required by Standardization Institutions.
- The basis of this invention is a series of improvements made to an automatic panic lock which assures being able to attain a sufficient range of security.
- The object of the invention is to provide an automatic panic lock as defined in the claims.
- The present invention relates to an automatic panic lock of the type having a spring-loaded automatic locking, and which can always be unlocked with the inner spindle and can only be unlocked with the outer spindle when the clutch is in the suitable position; the follower being formed by a slotted one-piece body housing a follower plate in its slot, and the inner spindle being permanently attached to a window of the actuating follower plate with its end, and the outer spindle being linked to the actuating follower plate only when the clutch end cotters the slotted one-piece body with the linking end of the actuating follower plate.
- As a result of this assembly, the existing lock system with followers formed by several parts is improved, being now a single surrounding follower body which internally houses a follower plate. Since it is not formed by several parts, the linkage of the stops does not have to be adjusted, so the strength resistance is greater; and since it is a single body, it is a more rigid element with a larger friction surface, complying with the strict controls of up to 200.000 life cycles because the wear will be less. Therefore, resistance to lock tampering is greater, and less wear caused by friction is obtained.
- Another feature of the invention is that it incorporates a clutch end and a ball and socket joint which is linked to the spring rod. This configuration allows the rotation of the spring rod to take place in the ball and socket joint, unlike previous embodiments in which the rod rubbed against the inside of a clutch wheel and caused the breaking due to bending of the rod with fatigue. However, in this embodiment friction in the spring rod is prevented as a result of the linkage thereof with the ball and socket joint that absorbs stresses and allows the angular clearance, prolonging the service life of the clutch and therefore increasing user safety.
- According to the invention, the body of the latch bolt comprises a flat edge on which a wheel anchored to the chassis is disposed. Rolling on the tail of the latch bolt is thereby obtained in order to maintain the latch bolt in its operational line and thereby facilitate the linear stability of the latch bolt and prevent unwanted rotational pitching, thereby preventing an incorrect locking of the lock or its interference with the blocking bar. This therefore increases the service life of the latch bolt and accordingly user safety.
- Another feature of the invention is that the central arm comprises a guiding cavity in contact with the stem of the guard, and with a riveted wheel of the central arm in sliding contact with the lever plate. In other hand, the chassis comprises a riveted shaft to which the central arm and an actuator lever are joined, both the central arm and the actuator lever being able to rotate with respect to said riveted shaft. The actuator lever comprises a protrusion disposed close to a protrusion of the lever plate. Therefore, since all the elements are linked together, the assembly is operated at the same time, allowing, in the driving of the lever plate, the protrusion of the lever plate to hit against the protrusion of the actuator lever and remove the blocking bar, allowing the unlocking of the door. Connection problems between elements are thereby prevented, and there are no clearances, prolonging the service life of the lock.
- Another particularity of the invention is that the lever plate comprises the egg-shaped spring housing with an egg-shaped perimetric configuration in the form of a teardrop, wherein in its larger egg-shaped part the size is slightly greater than the circular section of the cylinder of the spiral spring, and wherein in its smaller egg-shaped part is the size is slightly larger than the fixed short arm of the spiral spring. As a result of this embodiment, the spring housing of the lever plate houses a spring with a special spiral configuration which forces its short arm to be centered and secures the lever plate in its correct position by tensing the position of the central arm. The fixing of the spring is thereby advantageously and efficiently resolved, preventing the use of two stems and achieving the same effect as a result of the configuration in the form of a teardrop, without requiring using additional elements. Therefore, it is possible to prolong the service life of the lock due to the connection problems, which can be generated by the use of a larger number of fixing elements, are avoided.
- The linkage of the inner and outer spindles is performed by means of a set screw with a rotating clearance in the order of 180° with respect to the thread pitch of the set screw and with the facing ends of both inner and outer spindles having respective alignment marks.
- This embodiment enables an allowance for the clearance of the handle of the door, this clearance being necessary for actuating the actuating follower plate such that the inner spindle is prevented from driving the outer spindle, thereby achieving the actuation mechanism necessary for the single-part embodiment of the slotted one-piece body, and thereby providing greater user safety and privacy.
- Finally, another feature of the invention is that the cross-section of the lever plate has a profile configuration of thickness greater than the width of the latch bolt.
- As a result of this configuration, if for any reason the door is left unlocked with the lever plate actuated, in the event of an impact due to the closing of the door, the risk of distress and wear of both the latch bolt and the lever plate is reduced, thereby preventing deterioration of the lock and assuring a correct operation of the same.
- These and other features of the invention will become evident in view of the following description.

- In the attached figures an automatic panic lock 1 according to a preferred embodiment of the invention is shown. Said lock 1 is of the type of locks having a spring-loaded automatic locking, and which can always be unlocked with the
inner spindle 2 and can only be unlocked with theouter spindle 3 when the clutch is in the suitable position. In the preferred embodiment of the invention, the lock 1 comprises a follower being formed by a slotted one-piece body 4 housing anactuating follower plate 5 in a slot 4a of said slotted one-piece body 4, the inner spindle (2) being permanently attached to a window 5a of the actuatingfollower plate 5 with its end 2a. Theouter spindle 3 in turn is linked to the actuatingfollower plate 5 only when theclutch end 10 engages the slotted one-piece body 4 with a linkingend 5b of the actuatingfollower plate 5. - As observed in the enlarged detail of
Figure 1 , using a single slotted one-piece body 4, surrounding therein anactuating follower plate 5, a greater strength resistance and a larger friction surface are achieved, whereby reducing wear and thereby prolonging the service life of the lock 1 and increasing user safety. - Being the slotted one-
piece body 4 unengaged, only theinner spindle 2 rotates the actuatingfollower plate 5, which is connected to theinner spindle 2 by means of its end 2a.I In this case, theouter spindle 3 does not drive the actuatingfollower plate 5 during its rotation, so the door only unlocks from the inside and not from the outside. Rotating theinner spindle 2 it rotates the actuatingfollower plate 5 which with itsoperating blade 5c acts on acentral arm 15 allowing the unlocking of the door. - On the contrary, if the slotted one-
piece body 4 is engaged theclutch end 10 is located in therecess 4b, shown inFigure 6 , of the slotted one-piece body 4. In this way, theouter spindle 3 is linked with the actuatingfollower plate 5, since theclutch end 10 engages the slotted one-piece body 4 with the linkingend 5b of the actuatingfollower plate 5. Consequently, upon rotating theouter spindle 3 it rotates the actuatingfollower plate 5 which in turn acts on thecentral arm 15, allowing the unlocking of the door. - As a result of this configuration, user privacy is achieved, allowing only the unlocking of the door from the inside and from the outside only when needed, and achieving this with a single slotted one-
piece body 4 that does not need to adjust the linkage of the stops between several elements, and therefore the strength resistance is greater. On the other hand, since it is a single body, it is a more rigid with a larger friction surface and thus less wear, thereby complying with the strict controls of up to 200.000 life cycles. - As seen in the enlarged view of
Figure 1 , the elements making up the clutch with the ball and socket joint 7 comprise aclutch end 10 and a ball and socket joint 6 which is linked to the spring rod 8. As a result of this configuration, the spring rod 8, which is housed inside the ball and socket joint 6 through the ball and socket joint hole 9, is subjected to less friction since the rotation of the spring rod 8 is carried out in the ball and socket joint 6. As a result of its angular clearance, it absorbs stresses and prevents breaking due to bending of the spring rod 8. In this way, the service life of the clutch is prolonged and therefore the user safety is increased. -
Figure 2 and thehidden detail 13a ofFigure 1 show the existence of awheel 13 anchored to thechassis 11 of the lock 1. Saidwheel 13 cooperates with the body of thelatch bolt 14b, on itsflat edge 14c, in the movement of thelatch bolt 14 during the locking of the door, maintaining thelatch bolt 14 in its operational line during sliding, thereby preventing the unwanted rotational pitching or interference with the blockingbar 12. Incorrect locking of the lock 1 or the unwanted activation of the blockingbar 12 are thereby prevented, generating less wear and thereby providing greater security for the lock. - As seen in
Figure 3 , thecentral arm 15 is linked by means of a guidingcavity 15a to theguard 17 through astem 17a, and positioned in sliding contact with alever plate 16 through a rivetedwheel 15b). Thechassis 11 comprises a rivetedshaft 23 through which thecentral arm 15 and anactuator lever 20 are joined, rotating both with respect to said rivetedshaft 23. Theactuator lever 20 comprises aprotrusion 20a disposed close to aprotrusion 16a comprised in thelever plate 16, as shown inFigures 2 ,3 ,4, and 5 . When theprotrusion 16a of thelever plate 16 collides theprotrusion 20a of theactuator lever 20 the blockingbar 12 is removed, allowing the unlocking of the door. This configuration, which keeps all the elements linked together, prevents allowances and prolongs the service life of the lock 1. - In the
hidden detail 18a of the egg-shapedspring housing 18 shown inFigure 1 and inFigures 2 ,3 , and5 , it can be seen that thelever plate 16 comprises the egg-shapedspring housing 18 with an egg-shaped perimetric configuration in the form of a teardrop and is able to receive the spiral of thespiral spring 19 in its larger egg-shaped part and the fixedshort arm 19a of thespiral spring 19 in its smaller egg-shaped part, as can be seen in the enlarged detail ofFigure 2 . In this way, thespiral spring 19 keeps thelever plate 16 in the correct position by means of the movablelong arm 19b of thespiral spring 19, the fixedshort arm 19a and thespiral spring 19 remaining inside the egg-shapedspring housing 18 of thelever plate 16, thus simplifying the mechanism due to it is not necessary to use additional elements, so that it is possible to prolong the service life of the lock 1 as they avoid connection problems that could generate the use of a larger number of fixing elements. - In the enlarged detail of the slotted one-
piece body 4 ofFigure 1 , it can be seen how theinner spindle 2 and theouter spindle 3 are linked by means of aset screw 21. Theset screw 21 is tightened as much as possible, attaching theinner spindle 2 and theouter spindle 3. Then theinner spindle 2 or theouter spindle 3 is loosened an angle, in the order of 180°, generating a gap between bothspindles mark 2b is made on theinner spindle 2 and anothermark 3a is made on theouter spindle 3, bothmarks inner spindle 2 andouter spindle 3. Themark 2b of theinner spindle 2 and themark 3a of theouter spindle 3 are thereby aligned. - In the future assembly of the
inner spindle 2 and theouter spindle 3, if the faces with themarks screw 21 is tightened, a gap will be available between theinner spindle 2 and theouter spindle 3 so that theouter spindle 3 can rotate without driving theinner spindle 2, which would drive the actuatingfollower plate 5, unlocking the door. This configuration allows, upon rotating theouter spindle 3 from the outside, the actuatingfollower plate 5 to not be rotated if the lock is not engaged, thereby achieving the desired user privacy function by using to that end a single slotted one-piece body 4. - Finally, as can be seen in the
cross-section 16b ofFigure 1 and in the profile view ofFigure 7 , another feature of the invention is that thelever plate 16 comprises across-section 16b having a profile configuration of thickness greater than the width of thelatch bolt 14. Therefore, if due to an oversight or due to cleaning the door is left unlocked with thelever plate 16 outside of the lock 1, upon impact of the door, the active ends 14a of thelatch bolt 14 are not reached, thus avoiding wear and deterioration of thelatch bolt 14, and thus assuring the correct operation of the lock 1.
