Definitions

  • the present invention relates to a device for locking and unlocking an emergency exit opening means and, more particularly, such a device mounted on an exit subjected to an electronic control and monitoring system.
  • opening devices generally panic bars, which must unlock these exits under the pressure of people, for rapid evacuation of the public in the event of an accident, such as 'a fire.
  • opening devices generally panic bars, which must unlock these exits under the pressure of people, for rapid evacuation of the public in the event of an accident, such as 'a fire.
  • these opening devices cannot be used without special supervision, failing which the exits would also be open for irregularly removing goods or introducing people.
  • the emergency exit opening members are kept locked by an electrical means, such as a live electromagnet.
  • electrical means such as a live electromagnet.
  • These means can be controlled from a central station, or by heat or smoke detectors, etc.
  • the unlocked position of the opening member corresponds to the absence of current in the electrical means.
  • the locking and unlocking device used must meet a number of requirements. On the one hand, when it is in the locked position, it is essential that it does not block when it is sent an opening command. It happens, for example, that a thrust is exerted continuously on the panic bar. This thrust, even significant, must in no case oppose the unlocking of the device. Conversely, the latter must be able to resist at best if violent pushes are printed on the panic bar in order to force it. In addition, the resistance of the device, like its unlockability, must be ensured by mechanical means, and not by leveraging the power of the electromagnet, because the latter must consume the least possible energy. Indeed, many electronic surveillance systems are used as anti-intrusion systems outside opening hours, in stores, for example. In general, for safety reasons, these systems are powered by batteries outside of opening hours. They must therefore have an autonomy of at least seventy-two hours which represents the duration of an extended weekend. It is therefore necessary to provide elements in these systems which consume as little energy as possible.
  • the device must be able to generate opening request signals as soon as a push, even a slight one, is exerted on the panic bar, said signals being processed by the electronic surveillance system, to warn the station. central, trigger timers before opening, etc.
  • the object of the invention is to provide a device which meets all these requirements and which, moreover, is simple, solid and easy to assemble.
  • the panic bar is carried, at its ends, by two pivoting arms in housings fixed by their bottom on the leaf of the outlet, of each side.
  • One of said boxes contains the lock proper, while the other contains the device of the invention.
  • the device comprises: a substantially horizontal finger extending said panic bar lever on the other side of its pivot axis, towards the bottom of the housing, a slide bearing on said finger and movable vertically, the upper front edge of which is in the form of a step, the side of said step being substantially vertical and the base slightly inclined towards the front, a transverse rod which can move between a rear position where it is in abutment against the side of said step, slightly above its base, when the slider is in the low position, and a front position where it is in front of the slider, a means for returning said rod to the front position being provided, said rod being carried by the lower arms of lateral links pivoting about a transverse axis situated above said rod, in the same vertical plane or slightly in front, when it is in the rear position, said rods also comprising rear arms directed towards the rear, - a fork with two branches, the base of which is connected to the rod of an electromagnet fixed in the housing, the free ends of the two branches cooperating with
  • said means secured to the slide has two arms acting on two microswitches connected to an electronic surveillance system by two independent lines.
  • the slide is slidably mounted on a vertical axis integral with the housing.
  • the inclination of the base of said step is between 12 °, approximately, and 15 °, approximately.
  • said slide comprises a horizontal transverse hole, of oblong section directed vertically, in which is engaged a guide rod secured to the housing.
  • the branches of said fork are plates parallel to the side walls of the housing, the rear sides of which have a notch, and the slide has lugs on its side faces, which are engaged in said notches.
  • the electromagnet is in the lower part of the housing and the lateral arms of said links are in abutment on the tops of the branches of said fork.
  • a transverse stop limits downward the movement of the finger of the panic bar arm.
  • said stop and the guide rod engaged in the hole of the slide form with the bottom of the housing, on each side, vertical guides in which are engaged the branches of said fork.
  • the panic bar is carried at each end by an arm such as 1, the two arms pivoting about the same horizontal axis. At rest, said arms are directed obliquely downwards, the panic bar being held between their lower ends.
  • the pivot 2 of the arm 1 is located in a housing 3 placed on one side of the door leaf and encloses the locking device of the panic bar, object of the invention, and the pivot of the arm on the other side is in a box containing the lock proper.
  • the housing 3 has a vertical bottom or plate 4., Figs. 1 to 4, with lower and upper horizontal returns, respectively 5 and 6, side walls 7 and a front cover, not shown.
  • Figs. 1 to 4 the front side wall has been removed to show the device.
  • the front cover has been removed in Fig. 5 and the lever 1 shown in part only.
  • the pivot 2 of the lever 1 is mounted between the two side walls 7 of the housing 3. With respect to the pivot 2, the lever 1 is extended towards the bottom 4 of the housing by a finger 8. At rest, the finger 8 is substantially horizontal, Figs. 1 and 2. Its underside bears against a stop 9 in the form of a horizontal pin held between the walls 7.
  • the slide 10 On the upper face of the finger 8, a slide 10 rests, shown in detail in FIG. 6.
  • the slide 10 has the general shape of a rectangular parallelepiped. Its lower corners adjacent to the bottom 4 have lugs 11 projecting from its lateral faces, FIG. 6. In the embodiment shown, the lugs 11 have a substantially square section, but it could have a completely different shape, for example circular.
  • the slide 10 Near its face opposite the bottom 4, the slide 10 is crossed transversely by a horizontal hole 12.
  • the hole 12 has an oblong section of vertical direction.
  • a horizontal guide rod 13 mounted between the walls 7, the diameter of which is very slightly less than the width of the hole 12.
  • Another hole 14, of circular section vertically crosses the slide 10, in its middle part. Through the hole 14, the slide 10 is threaded on a vertical guide pin 15 fixed to the upper return 6 of the bottom 4.
  • a spring 16 recalling the slide down.
  • the front upper horizontal edge, opposite the bottom 4, of the slide 10 is cut so as to form a step 17 whose base 18 is slightly inclined forward relative to the horizontal and whose side 19 is vertical.
  • the slope of the base 18 is approximately 12 °.
  • the rear face of the slide 10 has in its middle part a vertical groove 20, fairly wide and shallow.
  • the base of a microswitch stop 21 which will be described below.
  • the base of the stop 21 is fixed to the slide 10 by means of one or more screws.
  • the lower part of the housing 3 contains the body of an electromagnet 22 whose rod 23 is directed vertically upwards.
  • the rod 23 is made integral with a fork 24 shown in detail in FIG. 7.
  • the fork 24 has a general U shape with two vertical branches 25 joined by a transverse base 26.
  • the branches 25 are flat plates parallel to the side walls 7 of the housing 3.
  • the base 26 is a horizontal flat plate.
  • the branches 25 and the base 26 are in one piece obtained by cutting and folding.
  • the base 26 is substantially rectangular, slightly less wide than the spacing between the side walls 7 of the housing 3.
  • the spacing between the walls 25 is slightly greater than the width of the slider 10 between its side walls, but less than the width between the external faces of the pins 11.
  • the branches 25 have a particular contour. Their rear side, close to the bottom 4, has an oblong notch 27 whose sides are horizontal and the bottom vertical. The depth of the notch 27 is substantially equal to the width of the lugs 11. The lower side of the notch 27 is located substantially at one third of the height of the branch 25, while the upper side is close to the top.
  • the top of the branches 25 comprises, from the rear towards the front, a horizontal part 28, then a forward inclined part 29.
  • the front side of the branches 25 is formed by two vertical segments 30 and 31, the vertical segment lower 31 being more forward than the upper segment 30. The segments 30 and 31 are separated by a horizontal shoulder 32 slightly higher than the lower side of the notch 27.
  • the fork 24 is integral with the rod 23 of the electromagnet by its base 26.
  • Each branch 25, FIG. 5, is practically in contact with the adjacent side wall 7.
  • the upper part of each branch 25 passes between the adjacent wall 7 and the corresponding lateral face of the slide 10.
  • the lug 11 of the latter is engaged in the notch 27.
  • the rear side of the branch 25 is supported on the bottom 4 of the housing 3.
  • the upper segment 30 is in contact on the horizontal rod 13 while the lower segment 31 is in contact on the stop 9.
  • the bottom 4 of the housing 3, the rod 13 and the stop 9 therefore constitute a vertical guide for the fork 24.
  • the finger 8 of the lever 1 is less wide than the spacing of the branches 25 of the fork 24 and can therefore pass between them.
  • a horizontal transverse axis 33 fixed between the two walls 7.
  • Two rods 34 are pivotally mounted on the axis 33, respectively near each wall 7.
  • the rods 34 are flat and parallel to the walls 7. They each comprise, at the rear of the axis 33, an arm 35 which comes to bear on the top of the corresponding branch 25 of the fork 24, then, under the axis 33 , a wider arm 36. Between the lower arms 36, is held a horizontal transverse rod 37.
  • the lower arms 36 of the rods 34 are biased forward by springs 38 working in traction.
  • the springs 38 are fixed to a horizontal transverse pin 39.
  • the arms 35 of the links 34 take a low position, when the fork 24 is itself in the low position, that is to say when the electromagnet 22 is not supplied. When the fork 24 is in the high position, the electromagnet 22 then being supplied, the arms 35 are also in the high position.
  • the arms 35 of the links 34 can be lifted by the fork 24, by supplying the electromagnet 22.
  • the electromagnet 22 will only have to overcome the return force of the springs 38.
  • the arms 36 move back and the rod 37 comes to be positioned above the step 17, pressing against its vertical flank 19 and slightly spaced from its base 18.
  • the rod 37 is slightly offset backwards with respect to the axis 33 of the rods 34.
  • the slider 10 can therefore only be moved very slightly when the panic bar is stressed, after which the base 18 of the step 17 abuts against the rod 37.
  • the thrust on the panic bar is not transmitted to the fork 24, nor therefore to the electromagnet 22.
  • the power of the electromagnet 22 is cut while the panic bar is pushed, as the base 18 of the step 17 is tilted, the rod 37 will not be blocked forward and may still get away.
  • the upper part of the housing 3 has two microswitches 40 on each side. These microswitches are controlled by the abovementioned stop 21, fixed at the rear of the slide 10.
  • the stop 21 has a flat vertical rod moving on the bottom 4 of the housing 3 and, at the upper end of the latter, two arms 41 in the form of forward directed returns. These are the arms 41 which act on two microswitches 40, FIG. 5.
  • the stop 21 has lateral extensions 42 taken between guide plates 43 fixed to the side walls 7 of the housing 3. Note that the electronic monitoring system receives the status signals from the microswitches 41 by independent lines, so that the system offers double security, which increases its reliability.
  • the stop 21 may also include, if necessary, a means modifying the state of another set of microswitches when, once the device has been unlocked, the panic bar has been pushed and the slide 10 is in the high position, the signal produced signifying that the issue has been opened.
  • the device of the invention In normal operating conditions of the panic bar system, the device of the invention is in the locked position, FIG. 1.
  • the energized electromagnet keeps finger 24 in the high position.
  • the rod 37 between the links 34 is in the front position, above the step 17 of the slide 10. It is in contact with the flank 19 of the latter, but slightly spaced from the base 18.
  • the arms 41 keep the microswitches 40 open in the rest state.
  • the slider 10 drives the stop 21 whose arms 41 close the microswitches 40 which produce two independent signals which are processed by the electronic monitoring system.
  • the latter can trigger an alarm at the central station, as well as the start of a time delay after which, if no human intervention has taken place, the supply of the electromagnet 22 is cut.
  • the fork 24 then descends and releases downward the arms 35 of the rods 34.
  • the rod 37 is therefore no longer subject to the biasing force forward of the springs 38 and, if a push is exerted on the bar anti-panic, to the play of forces applied by the side and the base of the step 17 and to the reaction force passing through the axis 33.
  • the panic bar With the device unlocked, the panic bar can be pushed until the exit opens.
  • the rod 21, by the arms 41, or other arms, can act on other microswitches to deliver a signal indicating the opening.
  • the device can only be brought back into locking position if the slide 10 is completely lowered. This implies, on the one hand, that the panic bar has returned to its rest position in FIG. 1 and that, on the other hand, the slide 10 has not remained blocked.
  • the spring 16 is therefore provided powerful enough that such an incident cannot occur. Note that the return to the lower position of the slide 10 will bring the microswitches back to the rest state. Their status changes can be taken into account by the electronic surveillance system which can indicate whether the device can be locked again or not.
