Definitions

  • the invention relates to an electro-magnetic safety lock for emergency exits according to the preamble of claim 1.
  • a lock of this type is known from document FRA-A-2 166 533 lock in which the transmission of the movement of the electromagnet to the bolt is done by metal parts rubbing directly on each other. During a high operating frequency, wear of the parts can occur followed by seizure.
  • a lock as described in document FR-A-2 166 533 cannot therefore have dual use: lock for remote control of door opening-closing at a very high rate of use on the one hand due to its friction; and on the other hand, lock for use on emergency exits, for the drawbacks it presents. Admittedly, it can be pushed in, opened by a simple push, but after a certain period of operation, the wear and seizure caused by the mechanical friction of the parts means that the force necessary for driving in has varied in the direction of increase. up to blocking. This situation is therefore dangerous for a security lock.
  • the object of the present invention is an electromagnetic lock with multiple functions grouped into a single lock: electromagnetic lock known as positive which prevents friction and mechanical seizure, lock for emergency exits with adjustable driving force and which allows a second locking , not pushable, lockable remotely, by electric remote control, when the establishment ceases to be public, lock manually unlockable by key in the event of a breakdown.
  • a lock according to the preamble of claim 1 characterized by the characteristics mentioned in its characterizing part, which in particular relate to a main maneuvering electromagnet, an angle transmission system by bearings with balls with variation of the angular force at the end of the stroke, a double bevel bolt cooperating with a keeper with two ball bearings, a second electromagnet making it possible to block the end of the first.
  • Such a lock can be used for remote controls for locking access doors with a high rate of use, avoiding both the risk of seizure and the risk of self-locking if the door is pressed before the opening remote control. It can also be used for emergency exits from establishments open to the public, making it possible in particular to remote control the blocked locking and unlocking of all emergency exits by electric remote control, when the establishment is temporarily in a non-public situation such as large shops and museums for example.
  • Figure 1 shows an exploded view of the main parts comprising the frame (1) of the lock, a bolt (2) held between spacers (10, 11, and 12) on which is fixed a fixed plate (3).
  • a bolt (2) held between spacers (10, 11, and 12) on which is fixed a fixed plate (3).
  • spacers (10, 11, and 12) On a face of the bolt are fixed by a screw (7), two ball bearings (5 and 6) with interposed washers allowing the locking of the two bearings by their internal wheel, the external wheel remaining free to rotate.
  • These two bearings will be the articulation around which, thanks to the fixed plate (3) and a movable plate (4), an electromagnet (20) will transmit its movement in a movement perpendicular to its axis.
  • the ball bearing (5) will guide the bolt rolling in the oblong slot (13) whose length determines the stroke of the bolt and whose width is 0.2 to 0.3mm greater than the outer diameter of the bearing so that the latter can roll on either of the edges of the slot, without friction of metal parts.
  • the ball bearing (6) goes roll in an oblique slot (17) of the movable plate (4). This moves, guided by the two ball bearings (10 a and 11 a) fixedly attached to the fixed plate by the screws of the spacers (10 and 11), the bearings being locked by their internal wheel, the remaining external wheel free to rotate.
  • the movable plate (4) has two oblong slots (14 and 15) whose length determines the stroke of this movable plate and whose width exceeds by 0.2mm the outside diameter of the bearings, so that according to the movements and mechanical stresses printed during the raising and lowering of the bolt, the bearings (10 a and 11 a) will roll on one or the other of the edges of the slots (14 and 15) avoiding any friction with the movable plate.
  • the oblique slot (17) of the movable plate has a width of 0.2 to 0.3mm greater than the outside diameter of the bearing (6).
  • the obliquity of this slot is such that during the movement of the movable plate in one direction or the other, it causes the ascent and descent or rather the re-entry and exit of the bolt (2) out of the lock.
  • the bearing (6) rolling on one or other of the edges of the slot.
  • the oblique slot (17) has two slopes. One long (17 a), at about 45 degrees angle with the edge (18), the second slope (17 b), short, end of race, made with the same edge an angle of 10 to 15 degrees , angle of the same sign, that is to say that during the movement of the bearing in the slot (17) with double slope, crossing from one slope to another does not change the direction of movement of the bolt which differentiates the present invention from the prior art, in US Patent No. 1,946,384 in which not only is there no use of ball bearings, but also a similar oblique slot presents a change of angle at the end of the stroke but this change of angle causes the direction of travel of the bolt to change and makes this lock completely unbreakable, unlike the lock of the present invention.
  • the spacers (10, 11 and 12) each comprise one or two ball bearings (10 b, 10 c, 11 b, 11 c, 12 b, 12 c,) facilitating the movements of the bolt (2), rolling on the outer wheels of these bearings.
  • the movable plate (4) is attached to the plunger core (21) of the electromagnet (20).
  • the lock is in the locked position.
  • the core (21) came to bonding.
  • the spring (22) is compressed and the movable plate has been drawn towards the electromagnet, the bearing (6) rolling in the slot (17) has caused the bolt (2) to protrude out of the lock.
  • Figure (3) shows the unlocked lock, electromagnet (20) not powered, the spring (22) has pushed back the movable plate assembly (4) - core (21).
  • the ball bearing (6) rolled on the corresponding side of the slot (17) and caused the retraction of the bolt (2) (dotted in the figure).
  • Figure 4 shows a mode of cooperation of the bolt in the keeper.
  • the bolt (2) has its tapered end like a double bevel chisel (8 and 9). It will be introduced into a keeper (24) at the orifice of which there are two small ball bearings (25 and 26) sufficiently spaced so that the bolt does not lock between the two bearings at the end of its stroke. .
  • the bolt which begins its projecting movement does not need to be rigorously in front of the keeper. Indeed, one of the bevels comes to roll on one of the corresponding bearings and corrects the position of the door, obviating a possible insufficiency of the door reminder device called "groom".
  • Figure 5 shows another mode of latch-strike cooperation.
  • the bolt is bevelled and indented and has a ball bearing 31 at its end, blocked by its internal wheel on the bolt, the external wheel free to rotate, cooperating with a keeper made of a set of metal parts fixed by a bracket to the door.
  • This mechanical assembly consists of a kind of double-sloping groove that flares at the inlet orifice and tightens in depth.
  • Each wall of the groove is a folded or arched plate (24) with a surface slope (24 a) and a deep slope (24 b) longer.
  • Each arched or folded part (24), at the end of (24 b), is linked to a rectangular part (34) by a hinge pin (33), the two parts (34) joined by a screw (36) with double reverse thread, allowing the parts (34), and therefore the lower ends of the slopes (24 b) to be moved away and closer.
  • the two parts (34) once adjusted to their correct spacing are locked on the bracket (37).
  • the two arched parts (24) can deviate from one another rotating around the two axes (33). This spacing can be adjusted by another screw (35) with double reverse thread, allowing the distance and the approximation of the arched parts (24).
  • the two planes (24 b) By acting on the screws (35 and 36), it is possible to bring the two planes (24 b) parallel to the axis of the bolt and separated from the value of the diameter of the ball bearing. At this time, the planes (24 a) make a small flare, facilitating the introduction of the bolt into the keeper; the planes (24 b), parallel to each other, provide a strike plate, the walls of which are perpendicular to any driving force. In this condition, the electromagnet (20) being energized, the bolt is out, the lock is unbreakable, and can then be used as a lock for airlocks of banks or entry of buildings.
  • a proximity detector (23) is fixed on the fixed plate (3) opposite the end of travel of the movable plate. Coupled with a relay, it has multiple uses: end-of-travel indicator, bringing into play an economy resistor in series with the electromagnet.
  • the bolt can remain protruding out of the lock after the electromagnet (20) has been de-energized, thanks to a kind of key or stud (27) (FIG. 1 and 2) which can block the moving plate near the end of its stroke.
  • This stud is activated by a second electromagnet (29) of the pushing type, causing it to protrude through a hole in the fixed plate.
  • Figure 6 shows a longitudinal section through the stud (27), non-magnetic metal, brass or dural.
  • This stud is sheathed in its lower half by a magnetic metal tube (28), realizing with the coil (29) electro-magnet of the pushing type which, supplied, attracts the metal tube (28) therefore makes the stud (27) protrude.
  • the coil (29) is fixed on the fixed plate.
  • the pin or stud (27), when it projects, moved by the electromagnet (29), is one to two mm away from the edge of the movable plate when the electromagnet (20 ⁇ 21 ) is at collage.
  • the spring (22) pushes back the movable plate (4) by one to two mm and this hangs on the stud (27) which itself is blocked by the movable plate.
  • the bolt is then blocked projecting from the lock and the lock is closed in the absence of current.
  • the proximity detector (23) or a second proximity detector is placed opposite the end of the stud (27) and detects it in the extended position. This signal is brought back to a control panel.
  • a timed power supply can be used: first switching on the electromagnets (20 and 29), then switching off the electromagnet (20) two or three seconds before switching off of the electromagnet (29).
  • the electromagnet that held it must be de-energized.
  • the stud has its free end, without vis-à-vis, which makes it possible to place a proximity detector opposite its end to control it.
  • provision must be made for the possibility of a power failure and the possibility of mechanically actuating the lock.
  • FIG. 1 shows a key cylinder (39) (40) with a cam cam (38), quarter turn.
  • the cam is located in the same plane as the movable plate (4).
  • the barrel is fixed on the stationary body of the lock. Performing its quarter turn, the threshing cam pushes the movable plate to its complete end of travel.
  • the lock is mechanically locked in this way by a key. Carrying out the reverse quarter turn, the cam disappears and leaves the movable plate (4) pushed back - by the spring (22), the bolt enters, the lock is open. If the lock was blocked by the stud (27), the cam can unlock it, because it can push the moving plate until the complete end of its stroke. For safety reasons, it is advantageous to control the position of the cam, by a micro-contact which sends the information to the control panel.
  • the device according to the invention is particularly intended for the electro-mechanical remote-controlled locking of building doors, bank airlock doors, emergency exits from places open to the public and from all doors, in all cases where there must be access control or restriction.
