Definitions

  • the present invention relates to emergency exit devices, in particular to emergency exit devices of the panic device type.
  • the devices according to the invention are particularly suitable for installation on fire resistant doors and are designed to meet the requirements of general safety and of legislation relating to escape from buildings.
  • An emergency exit device is a device, the main objective of which is to enable a door to be opened at all times by hand or body pressure from the inside, not requiring the use of a key or any other object.
  • the first category are suitable for installation at locations which are not open to the public, and would only be used by individuals who could be given prior instruction in the operation of the device. Such locations would include, for example, lift machinery housings and transformer installations, where there is a risk of, in particular, fire, and it might be necessary to evacuate the location rapidly in an emergency.
  • the second category of emergency exit device known as a panic device, is suitable for installation in areas which are open to the public, for example public buildings, places of public entertainment, stores, schools and hospitals, where it is necessary for the panic device to give simple and effective escape through a doorway with minimum effort and without prior knowledge of the device.
  • Some fire resistant doors are manufactured by mass production methods, in a variety of sizes, and are produced for economy in standard designs which are to be fitted with mortise locks. In a particular building, the majority of the fire resistant doors, perhaps 80% of such doors, do not need to be fitted with emergency exit or panic devices, but a small percentage, typically 20%, of such doors do have an emergency exit or panic function.
  • Exit devices are known which are designed to operate rim-type locks, but these are not suitable for standard mass-produced fire-resistant doors.
  • Exit devices are also known which are designed to operate mortise locks, but these will have to satisfy the requirement of the proposed European standard referred to above, in particular those aspects of the standard which relate to the opening of the door under pressure, and to the number of operating cycles which the device must complete and still be operable.
  • the invention provides an exit device which comprises a housing comprising a back plate for mounting on a door and providing guide means for the rack of a rack-and-pinion mechanism and a rack-and-pinion mechanism characterised in that the rack is a closed rack which is retained within the guide means, and is free to move, to a limited extent, in a plane parallel to the plane of the back plate, and the pinion is adapted to receive the spindle of an anti-panic mortise lock; which device further comprises a lever handle pivotally mounted on the housing; co-operating projections on the lever handle and attached to the rack, such that operation of the lever handle drives the rack within the guide means, and biasing means tending to urge the rack in the direction opposed to that in which it is driven by the lever handle.
  • the lever handle is adapted to be fitted to a horizontal panic bar.
  • the lever handle is preferably fitted with one or more recesses, into which fits a corresponding projection or projections on a metal plate. This metal plate is fastened to a tenon for insertion in known manner in the horizontal panic bar.
  • the exit device according to the invention is adapted to receive the spindle of an anti-panic mortise lock.
  • anti-panic mortise lock is meant a mortise lock in which, on the inside, all unlocking functions are operated by the spindle.
  • the exit device according to the invention is particularly useful in the type of anti-panic mortise lock in which if the dead bolt is projected, the inside lever handle retracts the latch and dead bolt simultaneously. The outside lever handle retracts the latch bolt only. From the outside, the dead bolt operated by the cylinder key only. If the dead bolt is withdrawn, the latch bolt is operated from both sides by the lever handle.
  • a panic device 2 comprises a housing 4 which is mounted on a door 6.
  • the housing 4 comprises a back plate 8 holding a rack 10 of a rack-and-pinion mechanism 12, the pinion 14 of which rack and pinion mechanism 12 is adapted to receive the spindle 16 of an anti-panic mortise lock 18.
  • a lever handle 20 is pivotally mounted on the housing 4 at pivot 22 and has a projection 24 which is arranged to co-operate with a second projection 26 on a plate 11 connected to the rack 10.
  • a coil spring 28 is mounted on a pin 30 secured in the housing 4. One free end 32 of the spring 28 is urged against the wall 34 of the housing 4 and the other free end 36 of the spring 28 contacts one end of the rack 10. A face 38 of the lever handle 20 engages removable stop means 40 in the rest position of the handle 20.
  • the rack 10 is slideably mounted within guide means formed by the back plate 8 of the housing 4 and rollers 44, 46 which are mounted in the housing 4 and retain the rack 10 in contact with the back plate 8.
  • the rack 10 is fitted with two bosses 48, 50 which engage in elongated slots 52, 54 in the back plate 8 of the housing 4.
  • the rack 10 is a closed rack with teeth 56 which engage with teeth 58 in the pinion 14.
  • the lever handle 20 is provided with two recesses 60, 62 to engage projections 64, 66 on a metal plate 68, which is suitably manufactured from steel.
  • the plate 68 is fastened to a tenon 70 which is inserted into a horizontal panic bar 72.
  • a bolt 74 is screwed into a captive nut 76, to expand the tenon 70 to fit tightly within the horizontal panic bar 72.
  • An adjustment screw 78 as shown in Figure 1 is located in a threaded aperture 80 provided in the lever handle 20, to allow for adjustment of the panic device 2 at the time of its installation or after installation, when wear during use has caused an increase in the clearance between co-operating parts.
  • exit devices according to the invention when used as a panic device, would normally be installed in pairs, fastened at either end of a horizontal panic bar.
  • the exit device installed at the end of the horizontal panic bar adjacent to the hinges of the door is provided to give support to the panic bar and does not have any unlocking function.
  • This exit device can therefore be installed, for reasons of economy, without the rack and pinion mechanism required to operate the anti-panic mortise lock.
  • pressure on the lever handle 20 in the anti-clockwise direction causes the handle 20 to pivot about pivot 22 so that the projection 24 on the handle 20 engages with the projection 26 on the plate 11 and drives the rack 10 in an upward direction.
  • the pinion 14 is thus rotated by the interengagement of the teeth 56 and the teeth 58 by the upwards movement of the rack 10, and the spindle 16 of the anti-panic mortise lock 18 is rotated and all unlocking functions are operated.
  • the coil spring 28 urges the rack 10 to move downwards within the guide means, the pinion 14 and hence the spindle 16 of the anti-panic lock 18 are driven to rotate in the opposite direction, and the device is returned to its rest position.
  • the device can be adjusted by means of the adjustment screw 78 located in the threaded aperture 80 in the lever handle 20.
  • this screw is screwed in so that its point projects beyond the face 38 of the handle 20, this means that the stop means 40 is engaged with the angle between the handle 20 and the door 6 reduced, as compared to the angle of engagement when the screw 78 is withdraw.
  • the adjustment screw 78 may be screwed in to a greater extent, so that the exit device is dogged; that is, the bolt head is held in the withdrawn position until manually reset.
  • Such a dogging mechanism can be of value, for example, in a school or other public building during the day where the door is in constant use. Where the door is a fire resistant door and must be kept closed at all times, the adjustment screw 78 is designed so that only a limited amount of adjustment is available and dogging is not possible.
  • the stop-means 40 is removable, so that during installation of the exit device 2 the handle 20 can be raised above its usual rest position in order to expose the fastening screws or bolts.
  • the exit device acccording to the invention is designed to operate an anti-panic mortise lock of the type described above. It has been found to be advantageous to coat certain parts of the lock, for example the latch and counterstrike, with a friction reducing coating such as polytetrafluoroethylene. This coating has the effect of reducing the friction between the lock parts and hence the load required to operate the exit mechanism. It has also been found advantageous to use an anti-panic mortise lock in which a roller is inserted, in known manner, in either the latch or the counterstrike, in order to reduce the friction between the lock parts. The reduction of friction has been found to be particularly important in satisfying the requirements of the draft common European Standard, in particular that test covering the opening force to be applied to a door loaded with a standard static force.
  • the device according to the invention can be attached to single or double doors of either hand, and to both the active and inactive leaf of double doors. Where the doors are double doors they may be fitted in known manner with door sequencers in order to ensure the correct sequence of door closing, without affecting the operation of the exit device according to the invention.
