Definitions

  • the present invention relates to an access locking device.
  • the field of the invention is the locking of access to a ladder, either from the ground to climb it, or from an upper platform to access a lower level, in particular below ground level.
  • a ladder to climb
  • an upper platform to access a lower level, in particular below ground level.
  • access control devices meet different requirements. For example, certain recommendations or recommendations require that the locking can be or, more demandingly, must be reactivated by the user authorized to cross it, so as to prevent another crossing. In this case, the device should be able to be deactivated by this user when he wishes to leave the protected zone.
  • the most widely used lock because the simplest and least expensive, and of almost universal use, is a panel associated with a padlock. It requires, in fact, no external energy input other than that of the user. The limit of use of this lock resides in the need to be close to the padlock to open or close it. The possibility or, even more, the obligation of a reactivation of the condemnation after the crossing of the access by the user is not possible.
  • the main object of the invention resides in the means offering at least the possibility, for a locking device with padlock, of a reactivation of this locking behind the user who has just crossed it and by this user himself.
  • Secondary objectives are also achieved by the invention, in particular that of establishing a constraint for the user so that he can only cross the access after having placed the device in a state which allows automatic activation of locking behind him.
  • the device comprises two operating members of one of said lock elements to disengage it from the other of said lock elements against the effect of a return member tending to maintain the aforesaid state of engagement .
  • the first maneuvering member is arranged to be made maneuverable by the user by opening a padlock, to open the locking panel, and can be made non-manoeuvrable by the same user by closing said padlock after it opened the panel.
  • the second operating member is arranged to be freely maneuverable by the user having crossed the condemnation.
  • the lock element provided with the maneuvering member is either mounted movable relative to the structure of the ladder, or mounted movable relative to the panel.
  • the lock element equipped with the operating member is movable relative to the panel.
  • These embodiments are the preferred ones of the invention because they lend themselves better to equipping ladder locking devices, in particular with crinoline, which consist of a panel surmounted by a cover, at the level of which the second maneuvering member of this lock element is formed by a release pedal.
  • the first lock element comprises a bolt mounted to slide on the panel so as to project under the effect of a return member outside the edge of the panel opposite to its articulation in order to be able to penetrate into said second latch element in the form of a keeper carried by the ladder structure.
  • This bolt is provided with a first abutment for a first movable drive abutment carried by said first member for maneuvering the bolt against the effect of its return member, and a second abutment for a second abutment mobile drive also against the effect of its return member, coupled by means of a transmission chain, such as a linkage, to a pedal which is located at the top of the panel and which forms said second operation, the first drive stop being immobilized on the panel by means of the aforesaid padlock.
  • the padlock is placed between a fixed lug of the panel and a lug secured to the first operating member of the bolt.
  • the padlock constitutes the locking means of a cover which folds over a pull tab of the first operating member projecting from the outer face of the panel.
  • the embodiments above illustrate devices which offer the user the possibility, of a reactivation by the user himself of the blocking that he has just unlocked and is about to cross.
  • the invention also relates to more complete devices which meet the requirement, not only of a possibility, but of an obligation of reactivating the condemnation when it has just been deactivated.
  • the aforesaid first drive abutment belongs to a bolt which slides relative to the panel when the padlock is withdrawn, over a fraction of the race, less than that necessary for complete release of the bolt from the striker, limited for this purpose by a latch carried by said panel and movable between two states, one active reached when the padlock is removed and the other inactive when the padlock is put back in place and closed after the bolt has traveled said fraction of the race, then authorizing the continuation of its race until the complete release of the bolt from the striker is obtained.
  • the panel comprises a fixed sheath in which slides a bolt locking lug.
  • the lug is pushed into an active state by the handle of the padlock passing through the sheath and into an inactive retracted state under the effect of a return spring, the lug cooperating with a pawl carried by the bolt opposing the sliding of the latter in the direction of the unlocking of the device and escaping the lug in a reverse sliding of the latch, the aforesaid latch having an operating pusher located near the sheath to be pushed back by the body of the closed padlock whose handle is engaged in the sheath and thus maintain the latch in its second inactive state.
  • the latch is thus maintained in its inactive state when the padlock, the handle of which is engaged in the sheath, is closed and the body of which acts on the pusher of the latch.
  • the invention also relates to embodiments functionally reversed with respect to those mentioned above, namely that the fixed striker is replaced by a fixed bolt and that the movable bolt is replaced by a sliding wall of the striker.
  • the drawing shows the part of the locking mechanism of the invention without the panel, that is to say the lock as mentioned above.
  • This part is arranged behind panel 1, visible to figures 2 to 4 , like an ordinary lock.
  • This panel is articulated on the fixed structure of the ladder around a horizontal or vertical edge axis, located opposite the edge carrying the lock
  • This latch comprises a bolt 2 which protrudes outside the edge la of the panel 1 to engage in a keeper 24 carried by the fixed structure E of the ladder.
  • the bevel 2a of this bolt allows its automatic engagement in the striker under the effect of a return member symbolized by the arrow F when the panel folds against the ladder, either manually or by means of a return member (spring hinges, cylinder, etc.) in a known manner .
  • the bolt 2 has a first stop 2b and a second stop 2c.
  • the stop 2b cooperates with a first movable drive stop 3a carried by a bolt 3 which forms the first element for maneuvering the bolt against the effect of its return member F.
  • This bolt 3 is also subject to the effect of a member G of its return to a state of rest which allows its immobilization with respect to the panel 2 by means of a padlock shown in the following figures.
  • a second stop 2c cooperates with a second movable stop 4, shown here schematically because it is a well-known mechanism for opening the locking panel which comprises a pedal P located at the top of this panel and a chain 5 of motion transmission with return to transform a depression of the pedal P into a movement of the bolt against its return member F.
  • the motion transmission chain 5 may comprise a linkage but also flexible links such as a cable or a chain, or rotating elements like pulleys or gears.
  • the bolt 3 comprises a pull tab 6 which passes through the panel 2 so that it can be padlocked and/or manipulated by a user.
  • FIG 2 thus illustrates the pull tab 6 secured to a tab 7 secured to the panel 2 by a padlock 8. Access can therefore only be unlocked by the holder of the key or holder of the padlock opening code.
  • the pull tab 6 can then be moved to the left of the figure and drive the bolt 2 by the stop 2a in order to disengage it from the striker where it is located.
  • the user can then cross the access and the panel 1 can be folded down on the ladder after the passage of the user. Locking is then active because no unauthorized person can unlock access. It is understood from these figures that the user who descends from the ladder can, by acting on the ad-hoc pedal, push back the bolt 2 by the action of the movable stop 4 on the stop 2c and thus de-condemn the access to take the ladder.
  • FIG 3a And 3b illustrate a variant in which the pull tab 6 is made inaccessible by being hidden by a cover 9 which can be lifted or folded down on the panel 2 around a hinge 9a, the folded down cover also being able to be padlocked on a tab 7a of the panel ( figure 3b ).
  • the re-locking is not automatic: it requires the intervention of the user who has un-locked.
  • the first unlock can only be completed if the re-lock is activated
  • the panel 1 not being visible on the latter, the bolt 3 has a cylindrical pull tab 6a.
  • the panel 1 is equipped with a sheath 10.
  • the latter has a through hole 11 which can accommodate the handle 12 of a padlock such as 8.
  • the panel comprises a box 13 under which the body of the padlock 8 can come into contact when the handle is locked.
  • the bolt 3 comprises a light 14 and a pawl 15 hinged at 15a on the rear face of the bolt 3 for, in a low position defined by a stop 16, its beak 15b interferes with the light 14. It also comprises a notch stepped bottom 17 with a deep part 17a and a less deep part 17b for reasons explained below.
  • figure 7 is a horizontal section of the figure 5 along the mean plane of the bolt 3 passing through the slot 14 (the panel having been omitted) and the figure 8 is a vertical section of this figure 5 by a plane passing through the axis of the sleeve 10. Note the presence in the sleeve 10 of a lug 18 for locking the bolt 3. This lug 18 is biased back by a spring to project into the through hole 11 of sheath 10.
  • a latch 19 in the form of a small lever, bent in L, tilting is articulated in the casing 13 around an axis 20 whose normal position, by the play of an end imbalance or a suitable spring, is such that the end 19a of this latch bears against the bottom of the deep part 17a of the notch 17 while its other end 19b projects downwards from the housing 13 to form a pusher.
  • the bolt 2 and the bolt 3 return to their first state, that is to say projecting from the edge of the panel for the bolt which can therefore engage in the keeper when the panel 1 is folded down while the bolt can pass the lug 18 by lifting the pawl 15 which falls in front of the lug to block it again.
  • the user was therefore only able to pass the condemnation after the latter had been reactivated by him, which satisfies the normative requirement if it exists.
