Definitions

  • the invention relates to a device for locking a door, provided with:
  • Such a device is known from practice and comprises a multipoint door-locking device.
  • a locking device is provided with at least two latches for securing the door to surroundings, for instance a post, at least with the door in closed position.
  • the latches of the known device are operable by means of the operating means mentioned, in particular for the purpose of locking and unlocking the door.
  • Such a device is for example known from DE 87 14 924 U1 .
  • An advantage of the known device is that with it, during for instance a fire, the door can be secured to surroundings relatively robustly. Moreover, due to the known locking device, the door can be locked so as to be relatively burglary proof.
  • a disadvantage of the known device is that operating the latches is relatively difficult.
  • the latches of the known device have, for instance, a relatively great closing resistance, rendering locking awkward and requiring relatively much force and/or energy. This closing resistance renders the subsequent unlocking of the door relatively awkward too.
  • the device is dangerous when the door is to be operated in an emergency situation, for instance a fire.
  • the known device is relatively susceptible to malfunction, in particular when the device comprises an electric three point lock. Therefore, the known device requires relatively much maintenance to ensure good functioning.
  • the operating means need to be of relatively heavy design in order to operate the latches well, rendering the known device relatively expensive.
  • document NL 101 84 57 C discloses a latch which is actuated under influence of fire detecting means when a fire is detected. After activation the latch can be operated by operating means for unlatching.
  • the present invention contemplates an improvement of a device for locking a door.
  • the invention contemplates a device for locking a door in an easy, more in particular safe, manner which can also be easily and rapidly opened in case of fire.
  • the device according to the present invention is characterized by the features of claim 1.
  • the device is characterized by:
  • the door can be locked in a simple manner by means of the first latch.
  • the first latch can be operated via the operating means, in particular for moving the latch between a door-releasing position and a door-locking position.
  • operating the operating means does not lead to the operation of the at least second latch, which is activated under the influence of fire detecting means when a fire is detected, so that the operating means can be operated with for instance relatively little force and/or energy.
  • the operating means can be of relatively simple and/or light design.
  • only one first latch is provided, which renders the operating means particularly easy to operate during normal use. By using only one first latch, the door can be opened and closed relatively rapidly during normal use.
  • the locking device provided with only one first latch is relatively unsusceptible to malfunction and is maintenance friendly.
  • the second latch When a fire is detected, at least by the fire detecting means mentioned, the second latch is activated, in order that the door is locked by this second latch. Preferably, the door is then locked both by the first latch and by the second latch mentioned, so that the latches secure the door to surroundings relatively robustly and/or in a form-retaining manner. As a result, undesired bending of the door can be prevented, which renders the door particularly fire resistive.
  • the door can moreover be unlocked again by means of the operating means, in particular in that the second latch is then also operable via the operating means. In this manner, the safety of the door is extra well ensured. This allows for instance the door, automatically locked in case of a fire, to be unlocked and opened for liberating victims from a space closed off by the door.
  • the operating means of the first latch can also be used for operating the second latch, at least after the second latch has been activated, the device can be designed with relatively few parts.
  • the automatically locked door is to be unlocked, i.e. by means of the operating means with which the locking of the door is also to be effected during normal use. In this manner, the door, automatically locked in case of fire, can be easily and rapidly opened by anxious bystanders, thus avoiding confusion about unlocking the door.
  • the invention further provides a door which is characterized by the features of claim 15, which offers the above-mentioned advantages.
  • the invention further provides an assembly, at least provided with:
  • Such an assembly can be advantageously used for, for instance, closing off a passage, for instance an opening of a post.
  • the door can then be locked and unlocked normally by operating the operating means.
  • the door can be secured robustly for closing off the passage in a fire resistant manner. In that case, unlocking the door is still possible, via the same operating means which are used for operating the door during normal use.
  • the assembly can for instance be supplied in separate parts and/or in partly assembled condition.
  • Fig. 1 shows a door 1 arranged in a post opening of a post 11.
  • the door 1 is provided with a locking device for securing the door to the post 11.
  • the present locking device comprises:
  • the first latch 2 and the second latches 3, 3' are arranged at a distance from each other, viewed in vertical direction.
  • the first latch 2 is located approximately adjacent the middle of the door 1.
  • the operating handle 4 is also located approximately at half the height of the door, at a position that is easy to reach for a user.
  • the second latches comprise a top latch 3, arranged at or adjacent a top side of the door 1, and a bottom latch 3' arranged adjacent a lower side B of the door 1.
  • the latches 2, 3, 3' are each provided in the door 1.
  • one or more latches can for instance be provided in or on the post 11 for securing the door 1.
  • Figs. 2 and 3 show the exemplary embodiment in more detail.

  • the operating handle 4 is coupled to the door 1 so as to be pivotal about a pivot 12.
  • the handle 4 is coupled to the first latch 2 by means of a coupling mechanism (not represented) for operating this latch 2.
  • the first latch 2 can be brought from a door-locking position shown in Figs. 2 - 5 to a door-releasing position shown in Figs, 6 and 7 .
  • the door is provided with, for instance, spring means or the like for moving the operating handle 4 and the latch 2 to the initial position shown in Figs. 2 - 5 .
  • spring means have not been represented in the drawing.
  • the present exemplary embodiment is further provided with a lock 9 with a dead bolt 10 for locking the door additionally, for instance independently of the operating handle 4.
  • a lock is known from practice and can be designed in different manners, for instance as a mechanical lock, a cylinder lock, electric lock and/or the like.
  • the top latch 3 is in a door-releasing position.
  • the fire detecting means are provided with a connection 5 disconnectable under the influence of fire, for keeping the top latch 3 in the door-releasing position.
  • the top latch 3 is coupled to the door 1 by a connection 5 disconnectable under the influence of fire.
  • the disconnectable connection comprises a material 5 that at least melts at a particular threshold value of an ambient temperature.
  • the top latch 3 is provided with spring means 8 for bringing the latch 3 automatically to a locking position extending partly outside the door 1, represented in Figs. 4 and 5 , at least after melting of the fire detecting means 5. In this locking position, the door 1 is secured to the post 11 by the top latch 3.
  • the part of the top latch 3 which, in the locking position, extends outside the door 1 is provided with a bevel, so that the door 1 can be moved with the top latch 3 along the post 11 when the door 1 is brought from an opened position of the door (not represented) to the closed position represented in Fig. 3 , in order that the top latch 3 can then secure the door 1 to the post 11.
  • the bottom latch 3' is designed in substantially the same manner as the top latch 3.
  • the bottom latch 3' can for instance also be secured in a door-releasing position by means of fusible material 5.
  • the bottom latch 3' can for instance be coupled to the top latch 3 such that an, automatic movement of the top latch 3 leads to an automatic movement of the bottom latch 3'.
  • the fire detecting means are arranged adjacent one or each second latch 3, 3' for the purpose of activating the latch(es) 3, 3'.
  • the fire detecting means can for instance be arranged in the door post 11, adjacent the door 1 and/or the door post 11, or at a distance therefrom.
  • the fire detecting means can for instance comprise a fire detector 105 provided on a ceiling P located nearby, which is represented in Fig. 1 .
  • the fire detecting means 105 can for instance form part of a central fire alarm system or the like.
  • the fire detecting means 105 can then for instance be designed for activating one or more second latches 3, 3' via a remote control (not represented).
  • the fire detecting means 5, 105 are designed for detecting fire at or adjacent the top side T of the door 1, in order that, in case of a fire, the door can be automatically locked, rapidly and safely.
  • the top latch 3 of the present exemplary embodiment is coupled, for instance directly or indirectly, to the operating handle 4 by means of a coupling means 16.
  • the coupling means 16 is designed for giving the operating handle 4 sufficient freedom of movement for operating the first latch 2 when the top latch 3 is still in the releasing position, which is clearly represented in Figs. 2 and 3 .
  • the coupling means 16 can for instance comprise a flexible cord, wire, chain or such flexible element, which flexible element 16 has not yet been tautened when the top latch 3 is in the releasing position represented in Figs. 2 and 3 .
  • the top latch 3 can also be coupled to the operating handle 4 in different manners.
  • the top latch 3 When the fusible material 5 has melted, for instance under the influence of fire, the top latch 3 is moved by the spring means 8 to the locking position represented in Figs. 4 and 5 . As a result, the coupling means 16 is tautened such that the top latch 3 can then be operated by means of the operating handle 4. As shown in Figs. 4 and 5 , the pivotal movement of the operating handle 4 indicated with arrow X then leads to a movement of the coupling means 16 indicated with arrow Y so that the top latch 3 is pulled to the releasing position represented in Figs. 6 and 7 .
  • the bottom latch 3' is also coupled to the operating handle 4, for instance in accordance with the coupling of the top latch 3 to the operating handle 4, by means of a flexible coupling element (not shown) or the like.
  • the bottom latch 3' can also be operated by means of the operating handle 4 after the bottom latch 3 has been moved to a door-locking position under the influence of fire detecting means.
  • the second latches 3, 3' are each in a door-releasing position.
  • the door 1 can then be locked and unlocked in a normal manner by means of the first latch 2 and the operating handle 4, and by means of the lock 9, 10.
  • the second latches 3, 3' When the fire detecting means 5, 15 detect a fire, the second latches 3, 3' are activated. The second latches 3, 3' then move, for instance simultaneously or successively, to a locking position for locking the door 1.
  • the door 1 is then secured to the post 11 by the first and second latches 2, 3, 3' at three different closing points, at least with the door in closed position. A further closing point can then be provided by the dead bolt 10, depending on the operating condition of the lock 9.
  • the door 1 can be secured to surroundings in a relatively robust and/or in a form-retaining manner.
  • the locking of the door can easily be undone by operating the operating handle 4 and the lock 9, which is shown in Figs. 4 - 7 .
  • first latch 2 on the one side, and the top latch 3 and bottom latch 3' on the other side can simply be pulled back simultaneously to a releasing position by the same operating handle 4 for instance via one or more coupling means 16.
  • a possibly locked lock 9 can then, for instance, be brought to a door-releasing position, for instance manually or automatically. Automatic operation of the lock can for instance take place under the influence of the fire detecting means, a central fire alarm system or the like, for instance when the lock 9 comprises an electric lock or the like.
