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.
- 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.
- 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.
- 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 can be activated under the influence of fire detecting means, 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.

Description
- The invention relates to a device for locking a door, provided with:
- at least one first latch for locking the door during normal use;
- operating means for operating this first latch.
- Such a device is known from practice and comprises a multipoint door-locking device. Such 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. During normal use of the door, 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.
- 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. As both locking and unlocking can be difficult, the device is dangerous when the door is to be operated in an emergency situation, for instance a fire. Further, 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. Moreover, the operating means need to be of relatively heavy design in order to operate the latches well, rendering the known device relatively expensive.
- The present invention contemplates an improvement of a device for locking a door. In particular, the invention contemplates a device for locking a door in an easy, more in particular safe, manner.
- To this end, the device according to the present invention is characterized by the features of
claim 1. - According to the invention, the device is characterized by:
- at least one second latch which can be activated under the influence of fire detecting means for locking the door;
- During normal use, 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. Here, operating the operating means does not lead to the operation of the at least second latch, which can be activated under the influence of fire detecting means, so that the operating means can be operated with for instance relatively little force and/or energy. In this manner, the operating means can be of relatively simple and/or light design. Preferably, 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. Moreover, the locking device provided with only one first latch is relatively unsusceptible to malfunction and is maintenance friendly.
- 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.
- After locking, effected through the fire detecting means, 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.
- As 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. Moreover, in case of fire, it is directly clear how 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:
- at least one door;
- at least one first latch for locking the door during normal use;
- operating means for operating the first latch;
- at least one second latch that can be activated under the influence of fire detecting means for locking the door;
- Such an assembly can be advantageously used for, for instance, closing off a passage, for instance an opening of a post. During normal use, the door can then be locked and unlocked normally by operating the operating means. In case of fire, 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.

top latch 3 of the present exemplary embodiment is coupled, for instance directly or indirectly, to theoperating handle 4 by means of a coupling means 16. The coupling means 16 is designed for giving theoperating handle 4 sufficient freedom of movement for operating thefirst latch 2 when thetop 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, whichflexible element 16 has not yet been tautened when thetop latch 3 is in the releasing position represented in Figs. 2 and 3. Naturally, thetop latch 3 can also be coupled to theoperating handle 4 in different manners. - When the
fusible material 5 has melted, for instance under the influence of fire, thetop 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 thetop latch 3 can then be operated by means of theoperating handle 4. As shown in Figs. 4 and 5, the pivotal movement of theoperating handle 4 indicated with arrow X then leads to a movement of the coupling means 16 indicated with arrow Y so that thetop latch 3 is pulled to the releasing position represented in Figs. 6 and 7. - Preferably, the
bottom latch 3' is also coupled to theoperating handle 4, for instance in accordance with the coupling of thetop latch 3 to theoperating handle 4, by means of a flexible coupling element (not shown) or the like. As a result, thebottom latch 3' can also be operated by means of theoperating handle 4 after thebottom latch 3 has been moved to a door-locking position under the influence of fire detecting means. - During normal use of the
door 1, thesecond latches door 1 can then be locked and unlocked in a normal manner by means of thefirst latch 2 and theoperating handle 4, and by means of thelock - When the
fire detecting means 5, 15 detect a fire, thesecond latches door 1. Thedoor 1 is then secured to thepost 11 by the first andsecond latches dead bolt 10, depending on the operating condition of thelock 9. In this manner, thedoor 1 can be secured to surroundings in a relatively robust and/or in a form-retaining manner. Furthermore, the locking of the door can easily be undone by operating theoperating handle 4 and thelock 9, which is shown in Figs. 4 - 7. Here, thefirst latch 2 on the one side, and thetop latch 3 andbottom latch 3' on the other side can simply be pulled back simultaneously to a releasing position by thesame operating handle 4 for instance via one or more coupling means 16. A possibly lockedlock 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 thelock 9 comprises an electric lock or the like. - It is self-evident that the invention is not limited to the exemplary embodiment described.
