Definitions
- the present invention relates to a method for actuating at least one movable part, in particular a space closure which can be moved within a predetermined range, and a device for carrying out this method.
- the door can be a swing door or a revolving door. This method of operation presupposes that the space in which the door moves during the opening process is free. However, this cannot be guaranteed in every case, because it can happen that someone has placed an object behind the door or that a person has stood in this room, etc.
- an optosensor in the upper region of the rear of a swing door, which is directed towards the floor. This sensor sends out a beam in the form of a cone. If an obstacle gets into this cone, then either the opening movement of the door is stopped or the door is not opened at all.
- the movements of the door wing can damage the optosensor. It is also necessary to lay cables up to the sensor along the upper edge of the door leaf, which connect this to the door control. These cables can only be covered at great cost, if this is possible at all, and they can also be damaged over time by the repeated pivoting movement of the door leaf.
- the diameter of the cone within which the sensor arranged on the rear of the door leaf is effective must not be too large. Because if the diameter of this active cone were too large, the sensor would detect the wall against which the door leaf is moving. In this case, the door leaf could not be opened completely. With such a small cone diameter, smaller objects may go unnoticed by the optosensor.
- the object of the present invention is to provide a device which is able to monitor the entire room, for example behind a door, and which does not have the above-mentioned and other disadvantages.
- FIG. 1 shows a perspective view of a first embodiment of the present invention, which also shows a section of a room in which a door is located, this door being closed,
- Fig. 3 is a block diagram of a device for controlling a drive of the door
- Fig. 4 is a front view of a second embodiment of the present invention, which comprises a double sliding door.
- Fig. 'L one of the corner sections is a perspective view of a room having a pivotable door 1.
- the door 1 is closed in the case shown.
- Fig. 2 shows the same corner part of the room as Fig. 1, wherein the door 1 is half open.
- the corner of the room shown has a floor 2 and two side walls 3 and 4, the side walls 3 and 4 meeting in a vertically running corner edge 5 of the room.
- the door 1 is embodied in the first side wall 2 and is arranged in such a way that it is in the vicinity of or at a distance D from the corner edge 5.
- the door 1 comprises a door opening 6 (FIG. 2), which is implemented in the first side wall 3.
- This door opening 6 extends upwards from the room floor 2 and is closed at the top by a horizontally running lintel 7.
- the door opening 6 is laterally covered by vertically extending cheeks 8 and 9. borders.
- the door 1 also comprises a frame 10, which can be of a type known per se. This frame 10 is inserted and fastened in the door opening 6 in a manner known per se.
- the door 1 further comprises a swivel leaf 11.
- This door leaf 11 has two vertically running side edges 14 and 17 which define the width of the door leaf 11.
- the door leaf 11 also has a lower horizontally extending end edges 15 and an upper horizontally extending end edges 19, which define the height of the door leaf 11.
- the inner side edge 14 of the door leaf 11 is pivotally connected to the door frame 10 via hinges 12 and 13 (FIG. 1) which are known per se.
- These door hinges 12 and 13 are thus on that side of the door 1 which faces the second room wall 4.
- the door hinges 12 and 13 or the internal vertical edge 14 of the door leaf 11 are located at the distance D mentioned from the vertical corner edge 5 or from the second room wall 4. In the case shown, this distance D is smaller than the width of the door leaf 11.
- the door leaf 11 can be driven during its pivoting movement by means of a motor (not shown), which motor drive can be of a type known per se.
- the one ends of the straight lines 41 and 42 meet at a point A, which lies on the axis of rotation of the hinges 12 and 13.
- the pivotable vertical edge 17 of the door leaf 11 lying away from the door hinges 12 and 13 draws a circular arc 18 in the area of the floor 2 during a pivoting movement of the door leaf 11, viewed in a vertical projection.
- This arc 18 intersects the other ends of the straight line 41 and 42 in points B and C.
- the pivoting range 20 of the door leaf 11 forms a section of a zone 45, which can be monitored for the presence of an obstacle with the aid of the present device.
- This detection zone 45 also includes a partial space 46, which is located next to the swivel area 20 and which is limited laterally by the outermost open position of the door leaf 11, on the one hand, and by the room side wall 4 located behind the open door leaf 11, on the other hand.
- the base area of this subspace 46 is approximately triangular and this triangle has points B, C and 0 as the apex.
- the point 0 is the point at which the room corner edge 5 intersects the room floor 2.
- a sensor 25 is attached to one of the room walls 3 and 4 in a stationary manner, in such a way that it is located in the area of the door 1, in particular in the swivel area 20 of the door leaf 11.
- This sensor 25 is attached to that surface of the side wall 3 or 4 which faces the door leaf 11 or the pivoting region 20 of this door leaf 11.
- the sensor 25 is attached to the first room wall 3, in which the door opening 6 is made.
- the sensor 25 is closer to that side edge 14 of the door 1 or of the door leaf 11 which is assigned to the door hinges 12 and 13.
- the sensor 25 is thus arranged between this side edge 14 of the door leaf 11 and the vertical corner edge 5 of the room.
- the sensor 25 is expediently arranged next to this side edge 14 of the door leaf 11 or next to the vertical leg of the door frame 10 lying here.
- the sensor 25 is arranged in the upper region of the door opening 6. In the case shown, the sensor 25 is practically at the height of the lintel 7 or at the height of the upper horizontal edge 19 of the door leaf 11. If the circumstances so require, the sensor 25 can also be arranged lower. be net than at the height of the lintel 7. In this case, the sensor 25 can be arranged, for example, half the height of the door leaf 11 or even just above the room floor 2.
- the sensor 25, which can be of a type known per se, is essentially directed towards the room floor 2.
- the effective field of the sensor 25 normally has the shape of a cone 26, the apex of which lies in the area of the sensor 25.
- the base surface 47 of the active cone 26 lies at least partially on a surface opposite the sensor 25. In the present case, the room floor 2 represents this opposite surface.
- the remaining parts of the cone 26 are directed against the room walls 3 and 4 or against the rear of the door leaf 11.
- the cone 26 can also be a slate, as shown in FIGS. 1 and 2.
- the sensor 25 can be designed such that the base 47 of the cone 26 has a circular or elliptical outer boundary.
- the base area 47 of the cone 26 also represents the base area of the detection zone 45 already mentioned above and it includes, among other things, the partial areas 20 and 46 already mentioned.
- the height of the sensor 25 above the room floor 2 and / or the direction of the sensor 25 relative to the room floor 2 and / or the beam path of the sensor 25 can be selected such that the arcuate section 48 of the circumferential lines of the cone base surface 47 with the arcuate boundary section 18 of the Opening or pivoting area 20 of the door leaf 11 coincides or lies outside the arcuate boundary section 18, as this is shown in Figs. 1 and 2.
- the sensor 25 is designed such that the section 48 of the outer boundary of the base area 47 of the cone lying on the room floor 2 lies outside the arch 18.
- the cone base 47 comprises a further partial surface 49, which is outside the swivel range 20 of the door leaf 11, but which can also be monitored by the sensor 25.
- the arcuate section 48 of the conical base surface 47 represents only one of the sections of the boundary of the base surface 47.
- This boundary of the base surface 47 is further defined by straight-line boundary sections 21 and 22 when the door leaf 11 is in the closed position.
- the first rectilinear border section 21 is located in the area of the lower edge of the first room wall 3 and it extends between points B and 0.
- This border section 21 comprises the area of the lower edge 15 of the door leaf 11.
- the length of this border section 21 is equal to the sum the length of the lower edge 15 and the length of the distance D.
- the second rectilinear boundary section 22 is located in the region of the lower edge of the second room wall 4 and it extends from point 0 to the arcuate boundary section 49.
- the routes 21 and 22 meet at one end in the Point 0, ie in the area of the vertical corner edge 5 of the room and they are, like the room walls 3 and 4, perpendicular to each other.
- the other end of the respective route 21 and 22 closes at one of the ends of the arcuate boundary portion 48.
- the base 47 also represents the floor of an imaginary spatial body, which extends practically upwards from the floor 2 to the upper horizontal door edge 19, where the sensor 25 is arranged. On the outside, this imaginary body is delimited by a curved surface which has the shape of a section of a cylinder jacket.
- the aforementioned arcuate boundary edge 48 of the base surface 47 also represents the lower edge of this curved side surface of the imaginary body.
- the sections of the side walls 3 and 4 which extend upward from the sections 21 and 22 represent the two remaining sides of the imaginary spatial body. These side wall sections meet in the corner edge 5.
- the lower edge 15 of the door leaf lies here 11 over this first distance 21. Since the door 1 arranged in the first room wall 3 or the side edge 14 of the door leaf 11 is at a distance D from the vertical corner edge 5 of the room, the length of the horizontal edge 15 of the door leaf 11 is smaller than the length of the first section 21, which extends from the vertical corner edge 5 to the freely pivotable vertical edge 17 of the door leaf 11, ie to point B.
- An angle alpha, which extends between the door leaf 11 and the second room wall 4, is practically 90 degrees when door 1 is closed.
- FIG. 3 shows in a block diagram a circuit arrangement for evaluating and processing the signals supplied by the sensor 25 and for forwarding control signals to the motor of the door drive.
- the sensor 25 is connected to a circuit device 27 for processing the signals supplied by the sensor 25, wherein this circuit device 27 can also be designed such that it controls the functioning of the sensor 25.
- the output of this circuit device 27 is output to a first input of a microprocessor or computer 28, where the signals obtained are processed or converted into signals for controlling the motor.
- the Computer 28 then delivers control signals to the motor control 29, to the output of which the motor for driving the door leaf 11 is connected.
- This circuit arrangement also includes a memory 24 which is coupled to the microprocessor 28. In this memory 24 signal patterns are stored, the purpose of which is explained below.
- the circuit arrangement according to FIG. 3 has a displacement sensor 40, which can be of a type known per se.
- This displacement sensor 40 is selected in accordance with the type of the movable part, ie whether the part can execute a pivoting and / or a translatory movement.
- the displacement sensor 40 is assigned to the movable part in such a way that it can track the part while this part is moving and that it can deliver a characteristic signal for the respective position of the part.
- the output of the displacement sensor 40 is connected to a second input of the computer 28.
- the information about the respective position of the movable part, which the displacement sensor 40 supplies to the computer 28, is decisive for the individual signal in question in the template, which corresponds to the respective position of the part.
- the position signal of the displacement sensor 40 determines the position of the respective individual signal in the template pattern.
- the respective position signal of the displacement sensor 40 determines the selection of that individual signal in the template which applies to the relevant position of the part.
- the decrease in the size of the opening space 20 is registered by the sensor 25. This is because the door leaf 11 itself initially acts as an obstacle moving inside the cone 26 of the sensor 25. In this case, the sensor 25 would normally send out a signal for stopping the door drive. However, the present device is designed such that the moving door leaf 11 is not regarded as an obstacle by the sensor 25, so that the door leaf 11 can continue its opening movement.
- the circuit arrangement is designed such that, when the sensor 25 is switched on, it firstly opens the door leaf 11, for example after the first installation of this device, if it is ensured that there is no obstacle in the movement area 20 of the door 1 or located in the detection zone 45.
- the sensor 25 delivers a chain of individual signals or signal samples to the microprocessor 28 which correspond to the individual positions or angular positions of the opening door leaf 11 with respect to the second room wall 4.
- the controller 27 can control the sensor 25 such that individual signals or signal samples are only scanned by the sensor 25 at certain angular positions of the door leaf 11 and are output to the microprocessor 28.
- the sensor 25 can continuously scan the movement space 20 of the door leaf, but the individual signals or signal samples are taken from the sensor 25 only at certain angular positions of the door leaf 11 and are sent to the microprocessor 28.
- the chain of the individual signals obtained during this test run is processed into a pattern in the microprocessor 28. This pattern is stored in memory 24 and serves as a template pattern during the operation of this facility.
- the sensor 25, while the door 11 is being opened also supplies a chain of successive individual signals corresponding to the opening angle alpha of the door 11.
- the individual positions of the door 11 are sensed by the displacement sensor 40.
- the microprocessor 28 continuously builds up a pattern from these individual signals in a manner which is practically the same as the formation of the template pattern during the aforementioned test run.
- the microprocessor 28 compares the pattern just built with the corresponding section of the template pattern already stored in the memory 24.
- the door control 29 assumes that there is no obstacle in the opening space 20 is located and the control continues the opening movement of the door leaf 11.
- this is evaluated by the microprocessor 28 as the presence of an obstacle in the opening area 20 of the door leaf 11 and the microprocessor 28 sends a signal to Stopping the door drive 29 from.
- FIG. 4 shows another possible application of the present method and the present device, namely on a sliding door 30.
- This door 30 has two sliding leaves 31 and 32, which can carry out a translational movement and which are assigned to an opening 33 in a wall 34 . This assignment can take place in a manner known per se.
- the sensor 25 is arranged practically in the middle of this door 30, where the front edges 35 of the door leaves 31 and 32 meet when the door 30 is closed. In the example shown, the sensor 25 is attached in the area of the lintel 7 of the door opening 33 and is directed towards the room floor 2.
- the axis of the active cone 26 of the sensor runs
- a displacement sensor 40 (not shown) is assigned to each of the door leaves 31 and 32 in such a way that it can track the movement of the relevant door leaf 31 or 32.
- the outputs of these displacement sensors 40 are connected to the computer 28.
- Such a device can also be used on a folding door.
- the test or calibration run described above is carried out, whereby a template for signal patterns is generated and stored in the memory 24.
- the individual sections of the pattern just generated in the microprocessor 28 during the opening movement of the door leaves 31 and 32 are compared with corresponding sections of the template. If there is a difference between the corresponding positions of the above-mentioned patterns, the microprocessor 28 evaluates this as an obstacle for the door leaf 31 or 32 and stops driving the door or the relevant door leaf 31 or 32.
- the template samples are built from the received individual signals during a calibration run of the present device if it is certain that there is no obstacle in the range of motion of the movable part 11 or 31 and 32. It has also been shown that the template patterns are assembled from successive individual signals supplied by the sensor 25. The respective individual signal in the template pattern thus belongs to a very specific position of the movable part in its given or possible range of motion. These positions include not only the positions between the end positions of the movable part but also the end positions of the same. In this way, the device for control the movement of the part in advance, which signal the sensor 25 should deliver in the relevant position of the movable part so that the part can carry out its movement.
- the sensor 25 delivers a different individual signal at a certain position of the movable part than is expected from the position sensor 40 on the basis of the position signal, then it means that there is an obstacle in the movement range of the part.
- the engine control 29 stops the engine running and the movement of the part is thereby interrupted.
- the device continues to work, so that the sensor 25 continues to supply individual signals from the detection zone 45 ah to the computer 28 even when the part is at a standstill, namely at predetermined time intervals.
- the computer 28 compares these further individual signals obtained when the part is at a standstill with that individual signal in the template pattern or the section of the movement pattern previously built with the corresponding section of the template pattern which corresponds to the given position of the part.
- the engine control system 29 assumes that there is an obstacle in the detection zone 45 and the part continues to stand still.
- This obstacle can easily be a stationary obstacle.
- the individual signals delivered by the sensor 25 begin the signal stored in the template and corresponding to this position of the part. This applies to the present device as a command to restart the drive of the part. In this way, door travel is only started when the detection zone 45 is free.
