Definitions

  • the invention relates to a switching system for a door with access control, thanks to which it is possible to connect the door component on which a person must act in order to open the door (e.g. a door handle or an anti-panic door handle) and the door lock.
  • the door component on which a person must act in order to open the door e.g. a door handle or an anti-panic door handle
  • the door lock e.g. a door handle or an anti-panic door handle
  • doors with access control the standard situation is that such a connection does not exist, so it is not possible to open the door at will.
  • Examples of doors with access control are fire doors, which are used to limit the spread of a fire, or security doors, which protect rooms that not everyone is allowed to enter.
  • the document EP 2 754 794 A1 relates to a switching system, the components of which are not almost all arranged within the door handle.
  • a hollow bearing body is provided, inside which two connecting elements are mounted, one for connecting the switching system to the door handle and the other for connecting the switching system to the door lock.
  • This switching system differs in that the two connecting elements are mounted in the bearing body, but are not rotatable about its longitudinal axis.
  • the object underlying the present invention is therefore to provide a switching system for a door with access control, which eliminates the above-mentioned inconveniences of the majority of the known solutions and which is a technical alternative to the switching system of the above-mentioned document EP 2 754 794 A1 represents.
  • a room with several doors can have door handles (or similar components) that are all the same, even if there are access controlled doors. It will also not be necessary to use a door handle (or similar component) to be replaced when a door without access control needs to be converted into a door with access control.
  • the connection between the door handle or a similar component and the door lock occurs when, due to the action of the insertion means, the insertion part of the insertion body is in the space enclosed by the two insertion seats, i.e. when the insertion body is in its active position.
  • the first and second connecting elements are connected to one another and this corresponds to connecting the door handle (or a similar component such as an anti-panic door handle) and the door lock, because one is connected to the first connecting element and the other to the second connecting element.
  • the opening movement that the door handle performs due to the person's influence is transmitted to the door lock and the door can be opened.
  • insertion means are active, which preferably comprise a rod which can be brought into a working position in which the rod holds the insertion body in its active position, thereby providing the connection described above which enables the door to be opened will be produced.
  • the choice to design the insertion means as a rod that can be moved back and forth ensures that the movement of the insertion body takes place in a safe and reliable manner.
  • the drive means are provided so that the movements of the rod are carried out.
  • the drive means comprise an electromagnet provided with a rod, so that exactly the rod of the electromagnet takes on the role of the insertion means. The movement of the rod into the working position occurs due to a magnetic field generated by the electromagnet.
  • the drive means comprise a compression spring and a the locking ring attached to the rod.
  • the rod that performs the role of the insertion means is the rod of an electromagnet, but in this second embodiment, the movement of the rod into the working position occurs due to the thrust of the compression spring arranged between the locking ring and the electromagnet.
  • This second embodiment is intended in particular for access control doors that must be able to be opened in the event of a power failure and in this embodiment the electromagnet serves to keep the rod in the rest position, that is to say to counteract the action of the compression spring, and it generates too For this purpose, a magnetic field whose polarity is reversed compared to the magnetic field generated in the first embodiment. If the electrical power fails, the effect of the electromagnet ends and the compression spring can move the rod to its working position.
  • the return movement of the plug-in body i.e. from its active position to at least one inactive position, can generally take place due to gravity alone as soon as the action of the plug-in means, i.e. the rod, ends. However, it is preferred that this return movement also takes place in a controlled manner.
  • return means are provided which are designed, for example, as a return spring and act on the plug-in body to return it to its active position. During the movement of the plug-in body to its active position, the plug-in means, i.e. the rod, compress the return spring, but as soon as the rod is no longer held in its working position by the plug-in means, the return spring is free to relax and return the plug-in body to its inactive position.
  • the return spring it is possible, as an alternative to the return spring, to control the above-mentioned return movement of the insertion body by means of a magnetic field.
  • the insertion part is designed as a permanent magnet and if the electromagnet is also able to generate a further magnetic field which, however (analogously to the case of the second embodiment), has a polarity which is reversed compared to the magnetic field responsible for moving the plug-in body into the active position, it is possible, by means of the magnetic field having a reversed polarity, to bring the rod of the electromagnet into its rest position and, as a result, because the insertion part of the plug-in body is magnetically attracted to the rod, also to bring the plug-in body into the active position.
  • the figures show a switching system for a door with access control.
  • a switching system for a door with access control.
  • Such a switching system is used to connect the door component that a person must act on to open the door (usually a door handle) and the door lock, because in the standard situation such a connection does not exist.
  • the switching system comprises a first 1 and a second connecting element 2, of which the first 1 is connected to the door component on which one must act in order to open the door, and the second 2 is connected to the door lock.
  • a door component is usually a door handle 10 or an anti-panic door handle 14.
  • Each of the two connecting elements 1,2 has a plug-in seat 1b,2b on its own side 1a,2a.
  • Fig.1 For example, you can clearly see the insertion seat 2b, which is identical to the insertion seat 1b, which you can see in Fig. 1 whereas only one area is seen.
  • the first 1 and the second connecting element 2 are mounted within a bearing body 3, which is hollow and is also part of the switching system. They 1,2 are rotatably mounted about the longitudinal axis AA of the bearing body 3 and, as shown in the Fig. 1 As can be seen, their sides 1a, 2a which have the insertion seats 1b, 2b are directed towards one another and they enclose a free space between them. This free space is accessible through an opening 3a, which is provided in the bearing body 3 and extends parallel to the longitudinal axis AA.
  • the bearing body 3 can, see the Fig. 1 , be formed from a middle body and two end bodies attached to the middle body by a snap connection.
  • the connecting elements 1,2 protrude with connecting areas from the bearing body 3, whereby by means of the Fig.4 visible connection areas, the connecting elements 1,2 are connected in a known manner to the door handle 10 or to the anti-panic door handle 14 and to the door lock (usually positively by means of square pins which are inserted into the receptacles provided for this purpose with a square cross-section; see e.g. Fig. 11 , in which a square pin 15 connects the door lock with the connecting element 2).
  • the switching system also has a plug-in body 4, which is arranged within the bearing body 3 and between said two sides 1a, 2a, see the Fig. 1 . It 4 is movable along a direction of movement BB, which is perpendicular to the longitudinal axis AA, from at least one inactive position to an active position, for example in the 9 and 10 are visible, stored.
  • an insertion part 4a of the insertion body 4 is not positioned in a free space limited by the insertion seats 1b, 2b, whereas in the active position, the insertion part 4a of the insertion body 4 is positioned in this freespace and it connects the two connecting elements 1, 2 to one another .
  • a functional but also physical connection is established between the door handle 10 or the anti-panic door handle 14 and the door lock, so that the effect exerted by the person on the door handle 10 or on the anti-panic door handle 14 is transmitted to the door lock .
  • Each insertion seat 1b, 2b is formed by two projections extending from the respective side 1a, 2a of the respective connecting element 1, 2 and enclosing between them a part of the said free space in which the insertion part 4a of the male body 4 is received when the latter 4 is in its active position.
  • the insertion body 4 also has two arms 4b which extend symmetrically from the insertion part 4a. At the end of each arm 4b a support body 4c is provided, see Fig. 2 which slides on the two sides 1a,2a of the two connecting elements 1,2. These arms 4b serve to keep the male body 4 balanced and to ensure that its movements are precise.
  • the projections forming the male seats 1b,2b also have flat lower surfaces on which the arms 4b slide during the movements of the male body 4 from its inactive position to its active position and vice versa.
  • the switching system also includes an anchoring body 5, which is used in particular in the Fig.4 , 11 and 12 is visible, and insertion means.
  • the insertion means serve, as will be explained below, to move the insertion body 4 from its inactive position to its active position and to hold it in the active position.
  • the anchoring body 5 is positioned in the door leaf, see e.g. that Fig. 11 , 13 and 14 , and has an interior 5a in which the door lock is accommodated. It 5 is also provided with fastening means, for example threaded holes and screws or the like, for fastening both the bearing body 3 in and out of it Fig. 1 shows that many components of the switching system are arranged, as well as the plug-in means.
  • the anchoring body 5 is positioned inside the door leaf when the door leaf is manufactured. If the door is an access-controlled door, the bearing body and the insertion means are also positioned at the same time so that the door leaf is ready to be connected to the door handle 10 or the anti-panic handle 14, as can be seen from the Fig. 13 and 14 in which the first connecting element 1 is visible, which extends through a hole provided for this purpose in the door leaf.
  • the anchoring body 5 is arranged with clearance inside the door leaf, in particular with clearance in a plane perpendicular to the longitudinal axis AA and containing the direction of movement BB, which makes it possible to compensate for the unavoidable construction tolerances that exist in the case of assembled doors and ensures alignment between the door handle 10 and the door lock.
  • the presence of the anchoring body 5 inside the door leaf greatly simplifies the subsequent arrangement of the bearing body 3 and the insertion means.
  • the insert means include, see the Fig. 1 and 3 , a rod 6 which, along the direction of movement BB, from at least a rest position in which it is not inserted into an opening 3a provided in the bearing body 3, into a working position in which it is inserted 6 into the opening 3a and the insertion body 4 holds in its active position, is movable. During this movement from the rest position to the working position, the rod 6 pushes the insertion part 4a of the insertion body 4 gradually into the free space limited by the insertion seats 1b, 2b.
  • drive means In order to drive the insertion means so that they move the insertion body 4 into its active position, drive means are provided.
  • the drive means comprise an electromagnet 7 comprising the rod 6.
  • the rod 6 is movable along the direction of movement B-B and from said rest position to said working position due to the effect of a magnetic field generated by the electromagnet 7 when its windings are crossed by an electric current.
  • the operation is as follows. The standard situation provides that the door cannot be opened, i.e. the rod 6 is not inserted in the opening 3a and the insertion part 4a is not inserted in the insertion seats 1b, 2b.
  • the electromagnet 7 must not be active and therefore it is not crossed by the electric current.
  • the electromagnet 7 is crossed by the electric current and it becomes active, generating the magnetic field which causes the rod 6 to be inserted into the opening 3a, which in turn inserts the insertion part 4a into the insertion seats 1b, 2b, thus making it possible to open the door.
  • the drive means comprise, see the Fig. 3 , a compression spring 8a, which is wound around the rod 6, and a locking ring 8b attached to the rod 6, in particular arranged in an annular groove in the rod 6.
  • the rod 6 in this case is also the rod of an electromagnet 7', but the electromagnet 7' of this second embodiment acts in a manner different from that of the electromagnet 7 of the first embodiment.
  • This second embodiment is specifically intended for this purpose to satisfy the need to be able to open the door even if there is a power failure, as is required, for example, in the case of doors located at the end of an escape route.
  • the compression spring 8a is the one that presses the insertion part 4a into its active position, whereas the task of the electromagnet 7' is to hold its rod 6 in at least a rest position and to counteract the effect of the compression spring 8a. How it works is as follows. The standard situation provides that the door cannot be opened, ie the rod 6 is not inserted into the opening 3a and the insertion part 4a is not inserted into the insertion seats 1b, 2b. For this purpose, the electromagnet 7' must be active and the electric current must pass through it so that its effect outweighs the effect of the compression spring 8a.
  • the insertion means and the drive means remain active until the door is closed again. As soon as the door is closed again, the standard situation is restored in which the door cannot be opened.
  • the direction of movement BB is in practice along the vertical, so that as soon as the plug-in means, ie the rod 6, no longer hold the plug-in body 4 in the active position - ie in the case of the first embodiment no more electric current is supplied to the electromagnet 7 or in the case of the second Embodiment: electric current is supplied to the electromagnet 7' - the plug-in body 4, in particular its insertion part 4a, moves into its inactive position due to gravity and thereby restores the standard situation of the door.
  • return means which act on the plug body 4 to return it to its inactive position as soon as the action of the plug means ceases.
  • Such return means comprise a return spring 9 arranged inside the bearing body 3 and partially wound around a guide projection 3b arranged inside the bearing body 3 and protruding from the inner wall thereof. Referring to the first embodiment, the return spring 9 is able to return the plug body 4 to one of its inactive positions as soon as the electromagnet 7 is no longer traversed by electric current.
  • the return spring 9 is able to return the male body 4 to one of its inactive positions as soon as the electromagnet 7' is crossed by the electric current and generates a magnetic field of reverse polarity which, by overcoming the resistance of the compression spring 8a, is able to move the rod 6.
  • the electromagnet 7 By reversing (analogously to what happens in the case of the second embodiment) the direction of the electric current passing through the windings of the electromagnet 7, it is possible for the electromagnet 7 to generate a magnetic field having a polarity that, compared to the magnetic field by means of which the rod 6 is moved when the door is opened is reversed. As a result of the effect of this having a reversed polarity Magnetic field, the rod 6 can also be moved from its working position to its rest position along the direction of movement BB.
  • the insertion part 4a of the insertion body 4 is made as a permanent magnet and if the rod 6 of the electromagnet 7 acts precisely on the insertion part 4a during its thrust effect, then it is sufficient to restore the standard situation, the direction of the electric current that flows through the windings of the electromagnet 7 crossed, to turn back. In this way, the magnetic field that moved the rod 6 to its working position is no longer active and in its place the magnetic field of reverse polarity becomes active, which moves the rod 6 to its rest position.
  • Two stop projections 3c protrude from the inner wall of the bearing body 3, as shown Fig. 2 emerges. These 3c limit the rotational movement of the first connecting element 1 about the longitudinal axis AA in both directions of rotation, which corresponds to a limitation of the movement of the door handle 10 or the anti-panic door handle 14, which are connected to the first connecting element 1. This happens because, during the rotational movement, one of the projections forming the insertion seat 1b abuts against one of the stop projections 3c.
  • the switching system also includes an electronic component 11 provided with three different LED lights corresponding to the three are assigned to different door situations: e.g. a color signals that the door cannot be opened; another color signals that the door can be opened and the third color signals faulty functioning, which can be caused by both electrical problems and an intermediate position of the plug-in body 4.
  • the electronic component 11 has, according to Fig. 4 , has a dovetail-shaped cross-section, and the door handle 10 has a seat 10a, which also has a dovetail-shaped cross-section and in which the electronic component 11 is slidably inserted.
  • the seat 10a see still the Fig 4 , on a removable part of the door handle 10, because this simplifies manufacturing.
  • a locking pin 12 which is inserted into the Fig.4-6 and 11 visible, is part of the switching system.
  • the locking pin 12 is arranged between one end of a return spring 13 for the door handle 10 and an inner wall of the door handle 10. In this way, the locking pin 12 enables the return spring 13 for the door handle 10 to be tensioned during the lowering of the door handle 10, see the Fig.5 , and it serves as an end stop for the return movement of the door handle 10 as soon as this 10 is released, see the Fig.4 .
