Description

[Detailed description of the invention] The present invention also provides a rotatable device that is pivotable about one axis, relates to safety devices for rotatable equipment.

capable of pivoting about one axis, such as being exposed to wind pressure or negative wind pressure; For rotatable or rotatable equipment, avoid undesirable effects such as misalignment or twisting of the equipment. Problems that don't exist arise. This applies especially to doors with pivotable rotors and revolving doors. These facilities should be equipped with the safety equipment proposed here for storm protection. It can be used as

From DE-O53815195, motor-driven rotating drive with steerable door A is well known, but there are control and cut-off devices for each field and attached to each field. At least one anti-rotation sensor prevents the door from opening due to wind pressure. Ru.

With this known wind pressure safety device, a special wind pressure safety device is required for each individual door. This is a drawback.

The method of using a sliding coupler in a wind pressure safety device uses the friction of the sliding coupler. Therefore, the adjustment value that should be released cannot be held for a long period of time. The drawback is that it is not possible to prevent the adjustment value from decreasing.

The same is true for toothed couplers1, which are usually secured from both sides by leaf springs or similar springs. They are pressed together and can only come apart when the force of the spring is exceeded. child Again, it is not possible to precisely adjust the preselected values.

If indexing bins are used, release of the coupler, i.e. rotating a revolving door, for example. It is no longer possible to do so if the safety device is switched on.

It is an object of the invention to provide equipment that is pivotable or rotatable about one axis, in particular A safety device for securing doors or revolving doors with rotor blades that can swivel to and when the equipment is subjected to forces, especially in the form of wind pressure or negative wind pressure. Prevents equipment from opening or shifting unexpectedly, and prevents the forces acting on the equipment at that time. If the preset value is exceeded, a safety measure will be taken that will no longer prevent the equipment from turning. The goal is to provide all equipment. In this case, the safety devices proposed here are especially important for equipment. Bearings prevent damage to parts and/or glass parts and protect them in hazardous situations. Do not interfere with the operation of the equipment.

This object is achieved by the features of claim 1.

In this case, the stop device interacts with the holding device to prevent the entire equipment from pivoting, and only A preset force applied from the retaining device to the holding device enables the equipment to pivot. The entire equipment is prevented from turning until it reaches a size that At that time, the holding device The equipment is secured by moving at least a portion of it away from the stop device. can be rotated.

Advantageously, the locking device is arranged on the equipment body, in particular fixed on the equipment body. .

To ensure that this safety device is effective even when forces are applied to the shaft of the equipment from various directions, Preferably, the holding device interacts with the holding device independently of the direction of rotation of the equipment.

This allows the wind pressure to, for example, cause the revolving door to rotate to the right or to the left. Even if the device acts to prevent the equipment from turning, it is equally prevented. At least 2 locking devices Equipped with multiple stopping points, it is easy to actuate regardless of the direction of the applied force. can be done.

The safety device according to the present invention is configured so that the equipment can be turned with a force that can be set in advance. In order to It is preferable to allow controlled play. This play or the resulting actuation Due to the angle, the equipment cannot be tightly clamped by the safety device and can only be used for a limited distance. For example, in the event of danger, you can move the equipment and make a run-up. can be done. This run-up allows the equipment to be accelerated, without applying any special force. The holding device can be removed from the stop device and the installation can be swiveled. wind pressure This allows the equipment to shut down gradually, rather than abruptly, as when a person pushes a revolving door. Since it is pushed toward a point, it is necessary to reliably prevent the equipment from shifting or twisting. can. If the force acting on the equipment exceeds a certain amount and there is a risk of damage to the equipment, the holding device automatically disengages from the stop device, thereby allowing the equipment to swivel. Therefore, damage can be avoided.

The stop points can be designed as cams on the cam plate for manufacturing and functional advantages. It is.

The stop surface of the stop point is preferably curved or rounded, so that e.g. To jump over a specific stopping point with an impact, such as when a stopping surface has a corner. There isn't.

For structural reasons and through long lever arms directing more force into the stop device Therefore, it is best to place this stop device away from the axis of the equipment, for example the axis of a revolving door. preferable.

Preferably, the retaining device is arranged above the retaining device in order to engage the retaining device with the stop device. It is also provided with a stop projection, in particular in the form of a running roll. This stop projection together with the retaining device act to prevent the equipment from turning, but at that time, this stop protrusion is shaped into a running roll. The formation reduces material wear and frictional forces between the stop device and the retaining device. It can be eliminated.

In the position where the retaining device and the stop device engage, a stop projection is arranged between the stop points. It is advantageous to In this case, the operating angle of the holding device is such that the running roll determined by the distance that can be freely moved between the groups.

In order to avoid frictional forces within the limits of the working angle of the holding device, the stop lug is It is advantageous to arrange it at a distance from the

In an advantageous embodiment of the invention, the holding device is mounted so that it can move freely. , connected via joints, preferably connected in series, in particular rods and/or It consists of individual parts in the form of plates or plates. By using a retaining device of such structure, and at least a part of the retaining device can be pivoted away from the stop device, making the installation easier. It is not necessary to pivot the entire holding device in order to enable the equipment to pivot.

Preferably, the retainer has at least four points of articulation, the first of which and the last joint are arranged so that they cannot be moved. This allows this retention Preferably, the holding device is two in order to adjust the holding device to the rest position. A tensioning device, in particular in the form of a tensioning spring, allows the position with the first stop to be It can be moved to any position. In this case, rest position means the functional position of the holding device. However, the spring force of the tension spring is large enough to move the retaining device to the first stop. It's good. The holding device or part of the holding device is moved to enable pivoting of the equipment. When moving, the spring force of the tension spring prevents the holding device or part of the holding device from pivoting. must not.

Preferably, at least one individual part of the retaining device has an adjustable second stop. is connected to the first stop and held in a stationary position. Shaped as a 4-joint mechanism through the locking device by fixing one of the individual parts of the holding device made Even if a force is applied to the retaining device, the retaining device will not be able to move unless the retaining device simply fails Mobility of the device is prevented.

The second stop is preferably pivotable by a movable stop part, in particular a fixed joint. The bearing, which is held in this way, can be adjusted by means of a stand.

Preferably, the pivoting of the stop part can be automatically controlled by a pivoting device. Stop Automatic swivel of the retaining part allows for individual swivel of the stop part or retaining device if required, i.e. The retention device can be prevented from functioning if it is pulled away from the part. Ru. In case of danger, e.g. in the event of a fire, the stop may be removed in such a way. The force acting on the retaining device can be removed and, for example, a revolving door can be blocked by the retaining device. It can be rotated without stopping.

The swivel is rotatably connected to a stop that is longitudinally movable. Preferably, it also comprises a reciprocating electromagnetic bar. Reciprocating electromagnet makes stopping parts easy can be turned with the necessary certainty.

In this case, the swivel device engages the stop part with the holding device only in the activated state. is advantageous. This ensures that, for example, if a danger occurs and the current is interrupted, the Ensure that the stop piece is disconnected from the retaining device to avoid applying force to the device. can be done.

Ensures that the stop is disconnected or removed when the reciprocating electromagnet is not activated. In order to ensure that the product and the retainer are disengaged, the rod of the reciprocating electromagnet has a tension spring. We are prepared.

The tension spring is there to keep the stop part always pivoted properly.

For holding the individual parts of the holding device there are stop elements, especially in the form of pressure rolls.

This pressure roll interacts noiselessly with the individual parts of the holding device and Can be pulled into place or pulled apart without substantial friction with the parts. It will be done.

The stop part only moved slightly due to the swivel power being cut off, which caused the A stop piece and a retaining device so that pivoting is possible and no force is applied to the retaining device. In the engaged state, a stop element is arranged in the end area of the corresponding individual part of the holding device. This ensures that the holding device is rendered inactive. for example, The tension spring on the rod of the reciprocating electromagnet moves the stop piece slightly, and the retaining device enough to separate from the stopper. For this purpose, the stop element acts as a pressure roll. Being formed helps.

If the holding device is not in the rest position, ensure that the swivel device does not swivel towards the holding device. In order to It can only operate if the area is in between. This additional safety measure is for example a sensor to ensure that the stop lugs or factures are in the area between the stop points of the stop device. This is possible by using appropriate switches. In this state, the retaining device The corresponding individual parts are also in contact with the second stopper due to the action of the tension spring, so the movable stop is prevented. The position for fixing the corresponding individual parts of the holding device is You can take your place. contact with parts of the swivel or detent or retaining device. Damage that can occur when turning with I can do it.

In the rest position, parts of the retaining device must be free of the stop that prevents the equipment from pivoting. At least one of the other individual parts of the holding device is provided with a stop device so that it can be moved Advantageously, it is elastically deformable, in particular contractible, by a predetermined force of . Retaining device configured as a four-joint mechanism with fixed first and last joints As long as a part of it is fixed, its four joints or parts thereof can be If the part is not deformable, it cannot be moved. Only by its structure can the holding device The part can be moved away from the stop that prevents the equipment from pivoting.

The further part is then preferably an elastically deformable rod, in particular a compression spring rod. stomach. In that case, the compression spring bar is stable against lateral bending, and the length of the bar is It can only be deformed in the direction.

It is advantageous that the spring force of the compression spring bar is adjustable, especially automatically adjustable. . Thereby, the holding device works in conjunction with the stop device to hold the equipment for a longer period of time. You can decide which power you don't need. The safety device according to the present invention is suitable for various rotations. Or it can be used for pivotable equipment.

In particular, the predetermined forces can be changed after assembly.

In this case, the spring force of the compression spring bar can be applied in particular to a recessed (1 mbus) screw or a linear -Easy adjustment with tension bolt adjustable by motor.

In an advantageous embodiment, the retaining device is an individual in the form of a lever connected to the final joint of the fixation. separate parts, and a plate with a stop projection, connected to the first joint, and between Consists of a compression spring rod connected to allow movement. 4 joints formed in this way can be easily manufactured as a holding device and meets high requirements regarding functionality and safety. satisfy.

The tension spring that brings the retaining device into its rest position is located at the connection point between the plate and the compression spring. Advantageously, it is located in the same area. In this case, the area of the connection location is This is the most advantageous area for applying forces to guide the object to its rest position.

In the following, special embodiments of the invention will be described in detail by way of example with reference to the accompanying drawings. explain.

The figure shows the structure of the safety device according to the invention in a top view.

Rotatable equipment 4, for example the axis of a revolving door, which is not shown in detail in the figure, is indicated by the number 2. vinegar. At a distance from the shaft 2 there is a stop device 6 in the form of a cam plate 14. This stopper The station 6 has two mutually spaced stop points in the form of cams 1o, 12 and cams 10. The stop surfaces 16 and 18 of 12 are rounded. In the area between cams 10 and 12, A running roll 20 of the holding device 8 is arranged. The stop device 6 is fixed to the setting Q4. ing.

The holding device 8 has a four-section structure and consists of a plate 60 equipped with a running roll 20. It is held so that it can move via a fixed initial joint 22. On board 6o, A compression spring rod 52 is connected via the joint 24 so as to be bendable and extensible. compression The end of the spring rod 52 on the opposite side from the joint 24 is also connected via another connection HJ26. and is connected to the lever 58. The lever 58 itself is connected via a fixed final joint 28. Fixed.

Therefore, the holding device 8 is in each case one fixed first joint 22, one fixed joint 22, the last joint 22, A four-joint structure consisting of a joint 28 and two movable joints 24 and 26 placed between them. It is constructed. Unless its movement is prevented by a retaining device 8 or a stop, The holding device 8 can be freely pivoted under the action of a force, with the lever 58 or the like and plate 6o pivot, moving compression spring rod 52 with it.

However, the purpose of the retaining device 8 is to prevent pivoting of the installation 4 about the axis 2. Therefore, as long as it is necessary to prevent the above-mentioned rotation of the holding device 8, the holding device 8 must be fixed by specific means. In that case, free rotation is maintained This is called the powerless state of the device 8. The holding device 8 is fixed by the first stop portion 32 and the second stop portion 32. This is done by the second stop 34.

The holding bag W8 holds the tension spring 3 disposed at the connection between the plate 60 and the compression spring 52. 0 to the stop portion 32, and the other end of the tension spring 30 is, for example, a pin. It is fixed at 62. The spring force of the tension spring 30 is such that the tension spring 3o is 8 needs to be designed so as to reliably contact the stop portion 32. The holding device 8 is The projecting protrusion 64 allows it to come into contact with the first stop 32, which is formed as a bolt, for example. standing. Therefore, the tension spring 30 forces the retaining device 8 into the first stop 3 An initial stress is generated that presses on 2. As you can see from the figure, the setting [4] is in the direction of arrow A. In the case of movement, the first stop 32 prevents the holding device 8 from pivoting unassisted. in this case , the running roll 20 is in contact with the cam 12, and the holding device 8 is held in place by the first stop 32. Further rotation of the fixture 4 in the direction of arrow A is first prevented.

In order to prevent rotation of the equipment 4 in the direction of arrow B, the area of the distal end 50 of the lever 58 and a second stop that hits the lever 58 via the pressure roll 48 as a stop element. There are 34.

According to the invention, the holding device 8 holds the turning of the equipment 4 via the running rolls 20. Only predetermined forces acting on the device 8 are blocked. predetermined power The running roll 20 slides on one of the two cams 10.12 if , so that the bearings of equipment 4 avoid damage to the parts and materials. , at least part of the holding device 8 needs to be moved. This necessary holding device 8 Alternatively, the movement of a part of the holding device 8 is possible by means of a compression spring rod 52, Depending on the direction of rotation, this compression spring bar is compressed or pulled apart. this When the compression rod 52 is shortened or expanded by a specific amount, the traveling roll 20 moves both cams 1 0.12 on one side, thereby setting i! 4 rotational movements are possible.

The spring force of the compression spring 52 is adjusted by a fixed bolt with a recessed (1 mbus) screw 56. It can be adjusted by the bolt 54. Further, the fixing bolt 54 is driven by a linear motor. The spring force can also be adjusted automatically instead of manually.

However, in order for a person to enter or exit a building, e.g. If you try to pass through equipment 4 that is not installed but is configured as a revolving door, The holding device 8 must not prevent or make it difficult for the device to pivot. Also, there is a danger For example, in the event of a fire, people can walk through the building unhindered to get to the building. You must be able to get out without fail. This is the minimum of both stop parts 32 and 34. This is also achieved by separating one from the holding device 8. In the example shown in the figure, arrow B In order to be able to freely turn the equipment 4 in the direction of The stop portion 34 is formed as a movable stop portion.

For this purpose, the second stop 34 consists of a movable bearing pedestal 36, which A pressure roll 48 is fastened to the end facing towards the lever 58 . The bearing is 36 can be rotated by a rod 42 connected thereto so as to be bendable and extensible. Ru. The rod 42 is part of a pivoting device 40 consisting of the rod 42 and a reciprocating electromagnet 44. . The reciprocating electromagnet moves the rod 42 towards the lever 58 only in the actuated state; This causes the bearing to engage the platform 36 or pressure roll 48 with the lever 58. Past Since the rod 42 moves only when the return magnet 54 is activated, if the current is cut off, , the bearing automatically moves the platform 36 or the pressure roll 48 away from the lever 58.

This bearing is operated by a tension spring 46 to allow the table 36 to pivot back toward the reciprocating electromagnet 44. The tension spring is unstretched in the actuated state of the reciprocating electromagnet 44. Ru. As soon as the current supply to the reciprocating electromagnet 44 is interrupted, the tension spring 46 pulls the bar 42. pulling back toward the reciprocating electromagnet 44, which causes the bearing to pivot the platform 36 and removes the pressure roll 48 from the area of the lever 58. The pressure roll 48 is connected to the rod 4 2 moves slightly in the direction of the reciprocating electromagnet 44, the holding device 8 can be rotated without power. It is arranged so that it can be used. For this purpose, the midpoint of the pressure roll 48 is located at the lever 58 is only slightly away from the end 50. Pressure is applied to the end 50 of the lever 58 is applied to the pressure roll 48 via the reciprocating electromagnet 44. After the movement, the carriage 36 is rotated by the pressure roll 48 during the rotation movement, The holding device 8 can be pivoted powerlessly.

As long as the protrusion 64 is not in contact with the first stop 32, the carriage 36 is securely in the position shown in the figure. In order to prevent the traveling roll 20 from actually turning, the reciprocating electromagnet 44 It can only operate when it is between 0 and 12. This can be done by e.g. Can be used and secured by a simple switch.

In order to avoid friction of the running roll 20 against the cam plate 14, the running roll 20 is stopped. It is located apart from the locking device 6 or the cam plate 14. Cams 10 and 12 are Due to the operating angle caused by the large distance, installation #4 is held completely by the holding device 8. It is not fixed so that it does not move very much.

Therefore, even in case of an emergency, for example in a panic situation, the bearing By the time 0 hits the cam 12, the equipment has turned in the direction of arrow A, and as the setting fM4 is Can be moved. As a result, equipment 4 accelerates and holds a larger force. acting on the device 8, whereby the setting fi4 causes the holding device 8 to be activated in case of an emergency. It can be turned even if it is closed. This means that the second stop 34 may engage the lever 58 in certain cases. The same applies when the machine cannot turn out of the stopping position.

In the safety device according to the present invention, the holding device 8 is automatically actuated by the reciprocating electromagnet 44. It is particularly advantageous to be able to In windless conditions, e.g. 34 need not be engaged with lever 58. However, above a certain wind speed , an electric switch causes the bearing to be safely moved by moving the platform 36 to the position shown in the figure. The device is activated.

The anemometer allows the sensed wind speed to increase, e.g. depending on the stroke or force, of the compression spring 52. A linear motor to adjust the spring force is controlled according to the strength of the wind. Therefore, it is possible to automatically adjust to a specific value.
