Description

çnou -. .. "now . n ,,. ; .. 4. 459 677 stage of opening the door the outermost end of the door the stem's shaft combination in a guide groove using spring forces and hydraulic or pneumatic steering system. This allows you to change the moment that the door the clamp directs by means of the hinge combination towards the door. The principle of operation is in itself usable, however however, this known solution is constructively quite complex and limited to their functional capabilities.

The object of the invention is to provide an improved and more versatile solution than before is known to the problem, that the opening of the door can be achieved with the smallest possible force and the closing of the door, however, the ligt. The object of the invention is furthermore to provide one solution, in which the door closer can also be used to advantage to locking the door, and in which it controls these different functions presuppose is possible to achieve simple and reliable. ' The object of the invention is achieved by a method according to claim 1 and with a device for applying the method according to claim 6. In accordance with the invention thus changes the position of the joint shaft combination in relative to the outermost end point of the door closer. Pâ this way the moment that the door closer is directed changes the door except at different stages of the door opening and closing in addition if necessary also when the door is in a completely closed position. affects the door closer construction changes easy way facilitate the counteracting moment This can be accomplished without in itself or that its somehow. internal You can do that in one go opening the door by reducing which is directed towards the door. Too closing of the door, the torque directed is increased in a corresponding manner towards the door to its maximum. In this way, one can accordingly with the place of use choose a sufficiently strong door closer, which ensures the closing of the door e.g. in places like are exposed to wind, without the door during the opening stage in ... u 459 677 the corresponding degree becomes unreasonably rigid. In addition, you can when the door is in a completely closed position advantageously use a door closer solution in accordance with the invention to prevent the door from opening so that the door the support point of the joint combination end is moved in a direction, where the moment of the door closer to the door significantly growing. The solution can be advantageously applied e.g. in fire doors for holding the door against the fire pressure.

If the support point in question is moved so that the angle between door hinge lead is reduced to a minimum, can by means of the invention can be achieved through the door closer a complete door lock, without having to use it at all of an actual, traditional locking mechanism. A door closer which works according to this can advantageously be connected to one major monitoring systems, bar central control device while monitoring different locking objects. wherein a preferably programmed several When the door closer is in conventional use can the movement of the shaft advantageous during the movement of the door then, when the door is longer support point in practice is performed open 1-3 °. Since the door is already almost closed, and there is no longer a danger that e.g. the wind drives up the door, the reduction of the torque can be beneficial started so that the door finished is easy when opening commenced. Similarly, the increase in torque can advantageously start immediately when the inertia as occurs right at the initial stage of opening the door is overcome, because after this the counterforces are relatively way significantly less. Of course you can the object and the purpose the decrease and increase of the moment temporally arranged to take place also at another suitable in accordance with location for the door.

The said movement of the support point can be advantageous that the end of the hinge combination is connected supported linearly movable achieved so, rotatable to a slider, 459 677 to a guide member attached to the door. The movement of the sliding member is provided with a drive device, e.g. one electric engine. A device in accordance with the invention can also be equipped with a control unit, with a which starts the drive the order at the desired open position of the door and moves the slider to a position assumed by the desired one the change in the moment that the door closer is aimed at the door. In addition, the control unit can when the door is closed arranged to move the slider to a position which entails that the door is locked._ The control means can advantageously be provided ' microcouplers for determining the position of the slider and for control of the operation of the drive device.

The invention is described in more detail below with reference to the accompanying drawing, in which Figures 1-5 schematically show the basics of the invention principle in different stages of the door closing, opening and figure 6 schematically shows a locking of the door which provided with a solution in accordance with the ningen, figure Ta and Tb show partly in section respectively from above a device for applying method according to the invention, figure 8 schematically shows the control principle for a device in accordance with the invention, Figure 9 shows a coupling application for ligation of the steering. one In the drawing, reference 1 refers to the door frame, to which the door 2 is rotatably supported by hinges 3. For the door frame 1 is connected a door closer 4, to which rotatable shaft 7 a shaft 5 is connected. The second shaft 6 is on one side led to the shaft 5 through the joint 8, and on the other side to a guide means 9 attached to the door 2 through the joint 11, whose support point can be moved in the guide groove 10 of the guide member 9.

In this way, the door closer U acts on the door 2 through mediation 459 677 of the shafts 5 and 6 with a torque 16 'rotatable about the shaft 7, whose respective size depends on the compression of the ooh herewith of the position of the door. In addition 16 'of the direction of movement as well as the position of the door closer's body and function. To separate from this nominal from the shaft 7 of the door closer mediable torques 16 'have in the drawing with the torque 16 shows the torque, which in reality affects the door through the joint 11 and at the hinge 3. the spring of the shutter the size of the torque is affected Figure 1 shows a situation in which the door is closed and shafts 5 and 6 are 1 a position where the opening counter force which the door closer 4 facing the door is in place minimum. This position is described by the distance A from the joint 11 from the hinge 3, i.e. the pivot shaft of the door. In this situation, then the door closer 'N through the power transmission shafts 5 and 6 and by step 11 to the door directed step 16 has been reduced regardless of the fact that the internal forces in the door closer H which counteracts the opening of the door has remained unchanged.

As a result, you get the initial stage of door opening facilitated.

When the door has been moved towards its open position, which is shown by the arrow 12 in Figure 2, require the opening force significantly. As a consequence of this the position of the joint 11 in the guide groove 10 is moved towards a position (arrow 13), where the moment directed towards the door through shafts 5 and 6 increase. This reduces the distance of the joint 11 from hinge 3, ie. the distance B in Figure 2 is less than the distance A in the initial position in Figure 1. In practice, the movement of the trail 11 reduces the start already when the door has opened about 1-30. in figure 3 the door 2 is completely open and where the moment 16 ' In the mode shown shafts 5 and 6 are in a position, which through these are directed towards the door reaches its maximum when the door is at the end of its closing motion. : ann - one can a-- - 4 --._ 459 677 In this case, the distance C of the hinge 11 from the hinge 3 of the door is as least.

In Figure B, the door is about to close and the direction of the movement is indicated by the arrow 1Ä. The trail's 11 distances from the hinge 3 is here at its minimum C, whereby the torque 16 'which affects the door through the joint 8 is as large as possible, which ensures the closing of the door.

Figure 5 shows the final stage of the door closing, when the door already almost completely closed. At this stage there is no longer any danger of the wind blowing up, for example door, so the position of the 11 support point of the joint can begin is moved (arrow 15) again towards a position in which the torque 16 ' effect on the door is at least in accordance with Figure 1.

The moving movement can advantageously be started when the door is still open about 1-3 °, because the door closer member in this case is already in its stage for the so-called. the final push, which in turn is likely to ensure closing the door. When one behaves in this way is the rigidity of the door completely minimized before the next opening.

In a practical experiment, the maximum distance A between was chosen. trail 11 and hinge 3 250 mm. 3N0 mm and to minimum distance C In doing so, it could be stated that, for example, at opening the door, it could require the opening the force with a device in accordance with the invention, i.e. by using 1 instead of the distance C of the distance A, reduced to almost half. Thus when the opening moment is normally about twice the closing moment, is in the relevant moment in a device according to the invention roughly the same size.

Figure 6 shows a solution according to the invention, according to which the position of the 11 support point of the joint has been moved in relation to the normal opening function of the door described above in opposite direction, so that shafts 5 and 6 have been moved on 459 677 over each other, ie. the angle between these is 0. Hereby locks shafts 5 and 6 with their joints the door completely, without any actual locking mechanism in addition is needed. The locking strength depends mainly on the durability of the door construction.

This application naturally presupposes that the control body 9 _guide groove 10 extends sufficiently far, i.e. at least to a position at the shaft 7. If one again instead for a complete locking only wish to stiffen the opening of the door, such as in fire doors against the fire pressure, this can be achieved so that the support point 11 of the joint does not moved to a position completely according to figure 6. In this case pictures shafts 5 and 6 a small angle, the door-directed torque is still significantly greater than e.g. when but the door closer to the shafts have a position shown in Figure 1-5. In these figures, the guide groove 10 is drawn much shorter than in figure 6.

Figures 7a and 7b show an application for performing the movement of the shaft 6 end of the shaft. the guide pin 11, which is located at the end of the shaft 6, by conveying the nut means 20 to the sliding means In this solution is supported 171 which can be moved in the guide groove 10 of the guide member 9 and which receives control through said control track 10. For the movement is the control means 9 provided with a drive device 18, which can be an electric motor and as through the transmission of the screw means 19 and the nut means 20 move the sliding means 17.

Figure 8 shows the basic principle of control in a construction according to the invention. For moving the sliding means 17 and for controlling the drive device 18 function, the device is provided: with a control unit 22, to which is input to indicate the position of the door a signal 2U from the sensor / coupling 23 and the signals 25 from the shaft As shown in Figure 7a, can Using From 6 end position sensor 21. constitute micro-contacts. and or the position sensors 21 these control signals e.g. the control impulses 459 677 the rotary movement of the shaft 7 of the door closer starts the control unit 22 the drive device 18 through the signal 26.

The drive device 18 function is stopped either with the microcontacts 21, which thus indicating the extreme positions of the shaft 6 end of the guide groove 10, or by means of said control pulses.

Figure 9 shows a coupling application for controlling the function of the electric motor 18, which provides relocation the movement of the shaft 6 exhales the fulcrum.

Wiring diagram shows the position in figure 1. In accordance with the position of the coupling 23, which indicates the position of the door, the relay 28 controls the contacts 27a and 27b. When the door is closed, the coupling 23 is also fixed and the relay 28 circuit is thus closed. Here is the relay 28 in its activated position and moves the contacts 27 to the lower position shown in Figure 9. Simultaneously with the door also opens the coupling 23, whereby the relay 28 circuit broken and relay contacts 27 are hereby moved to theirs upper position according to figure 9.

When the door support shaft 6 support point is moved from it one extreme position to the other are both contacts 21 closed. Just before the shaft 6 'has reached the extreme mode, it simultaneously opens the mode in question corresponding to the connector 21a or 21b. Hereby when the door- the support point 6 of the shank shaft is located in someone in the extreme position, one of the contacts 21a and 21b is open and the other closed. Depending on the contacts 27a and 27b and the position of the contacts 21a and 21b is the relays 29a and 29b circuit either closed or open, nâgondera and based on this determines the position of the contacts 30a and 30b analogously to what as described above. Furthermore, the position of the contacts 30 determines whether the circuit affecting the electric motor 18 is closed or not. In this way: the electric motor 18 gets its start and stop control. It should still be pointed out that in fig. 9 refers to the upper position of all contacts 27a, 27b, 30a, and 30b each a passive state of the relay 28, 29a or 29b in question corresponding position, and correspondingly refers to the .ann: man a » n una »Q a . 1 u nu; an- ? closes the coupling 23, 27b is moved again to its lower position shown in Figure 9. (2- ua m O\ \: ~ a the lower position of the contacts of the relays in question active states corresponding mode.

In Figure 9, the door is thus closed, so the coupling 23 is fixed and the circuit passes through the connector 27a. Since contact 21a is open, relay 29a is not activated and the contact 30a is in the upper position of the figure. On correspondingly, the contact 27b is open and 21b is fixed, so relay 29b is passive and does not affect contact 30b, which thus is in its upper position as shown in Figure 9. Hereby the contacts 30a and 30b are thus connected to the same pole the power source, so the electric motor 18 is not in operation.

When the door is opened, the coupling 23 and the contacts open 27a and 27b are moved to their upper position in accordance with figure 9. In this case, the relay 29b and the contact 30b are activated moved to its lower position. Then connect the electric motor 18 to different poles of the power source and starts thus, and begins to move the end of the door closer shaft 6 in the guide groove 10 of the guide member 9 (Compare Figures 1,2 and 7).

As a result, the contact 21a is closed, which, however, is not changes the state of relay 29a or contact 30a. the figure When the door is fully opened and the shaft 6 end moved to its second extreme position in the guide track 10, the contact 21b is opened and the circuit in the relay 29b is broken, the contact 30b being moved in location. its upper position, one pole of the source, which is why the engine stops. the figure to its upper Since the contact 30a continues to be in the electric motor 18 is connected only to the When the door at closing is longer only 1-30 open, it follows that the contacts 27a and Since the switch 21a is closed, the relay 29a and are activated the contact 30a is moved to its lower position. On the other hand since the contact 27b is now open, the relay 29b is passive, 459 677 10 why the contact 30b remains in its upper position. Hereby starts the motor 18. Because the contacts 30a and 30b in this position are connected to opposite poles of the power source in in relation to the opening position of the door described above, the motor 18 now rotates in the opposite direction, and begins to move the shank 6 shafts 6 end of the guide groove 10 back towards the original position. In this case, the contact 21b is closed. At the final stage of the movement, the contact 21a is opened, whereby relay 29a is passivated and moves contact 30a to it upper position. As a result, the engine 18 and the positions of the contacts and connections again correspond to what shown in Figure 9.

The example of the wiring diagram shown in Figure 9 only takes care of the movement of the door closer's shaft 5 and 6 so that the door can be opened more easily than normal and that of the door closure is ensured. However assumes the movement of the shafts described above 5 and 6 so that the door is locked by a separate guide. This can achieved e.g. by providing the control unit 22 with a programmable microprocessor, which provides the necessary additional steering. This can be done, for example, so that the microprocessor, after receiving a signal relating to door locking e.g. by the operator or from any control unit equipped with a timer, can be arranged to move the connections, contacts and the relays belonging to the wiring diagram in Figure 9 to a position, where the engine starts and rotates in such a direction, that it moves the end 11 of the door closer's shaft 6 in the guide groove 10 of the guide member 9 to a position assumed by the door lock, which is shown in figure 6. If desired, can the one shown in Figure 9 with mechanical couplings realized the start and stop control of the engine and the achievement of the door closure described above is replaced by a provided with a function program such as corresponds to the said functions, the different orders of which are realized on the basis of the signals Zä and 25 (figure 8) and the said by the operator or from the timed control unit microprocessor, 459 677 11 obtained signal relating to door locking.

The invention is not limited to the applications shown. without a number of modifications are conceivable within within the scope of the appended claims. the forms,
