Definitions
- the invention relates to a safety gear for a permanently installed
- the safety gear which is also referred to as a runner, is guided in a guide rail.
- the person to be secured carries a safety harness and is connected via a connecting means with the runner.
- the connecting means is attached to a stop point of the rotor.
- the catching device has a locking device, which is displaceable between a first, unlocked position and a second, the safety gear arresting on the guide rail position.
- a holding device retains the locking device in the first, unlocked position, and the locking device is biased in the second, locking position. In case of a crash, the locking device is triggered speed-dependent.
- the locking device has a pivotally mounted pawl, wherein the one end of the pawl has the stop point and the other end a detent and wherein the detent engages in the event of a crash in catching latches of the guide rail and thus prevents a crash.
- the pawl is biased by a spring in the arresting position.
- the locking lug of the pawl points downward, so that when climbing the latches of the guide rail are run over. When descending the user leans back slightly (backward pull), so that the pawl is brought into the unlocked position and the runner can move freely downward.
- safety gears with speed-dependent locking devices.
- a safety gear is described in DE 103 42 627 A1.
- the safety gear described therein has a spring-loaded pawl, at the non-locking end of which a follower roller is located, and an attachment point. If the person to be secured moves slowly and in a controlled manner down the climbing protection system, the feeler roller is guided over catching slots of the guide rail, whereby a spring always retracts the locking pawl into its starting position in good time so that the pawl does not engage in the catching tracks of the guide rail.
- a safety gear with a speed-dependent locking device is also known, wherein the locking device comprises a centrifugal clutch.
- a friction wheel rolls off when moving the safety gear on the guide rail, and its rotational speed is thus proportional to the speed of the safety gear.
- a retaining device is released by the centrifugal clutch, so that a prestressed latch is pressed into a recess in the guide rail and thus locks the safety gear.
- an emergency braking system for an elevator in which a generator determines an electrical variable, the Speed of the elevator corresponds.
- the locking device is triggered by an electromagnet and the movement of the elevator is stopped.
- the locking device itself consists of two pairs of brake shoes whose toothed outer edges can engage opposite guide rails of the elevator and bring the elevator to a halt by friction.
- the object of the present invention is to provide a safety gear, the locking device is responsive to speed, wherein the speed at which engages the locking device is adjustable.
- the safety gear has an electronic device for speed determination, which triggers the locking device in dependence on the speed of the rotor.
- the locking device Due to the electronic speed determination, the locking device triggers particularly quickly.
- the locking device has a holding device with an electromagnet, wherein the holding device is disengaged or released by the electromagnet is energized.
- the safety catch has an electronic control which activates the locking device by disengaging or releasing the retaining device when the speed of the runner exceeds a predetermined threshold speed, e.g. in a crash.
- the movable stop member is a movable pin or a rotatably mounted pawl.
- the locking device is a combination of electrical and mechanical security.
- the locking device on a two-piece pawl.
- One part of the pawl is the locking lug rotatably mounted on an axle.
- the other part forms a mechanical lever, which is also rotatably mounted, expediently on the same axis as the locking lug, and having the attachment point.
- the lever and the detent are held together by means of the holding device, so that the combination of lever and detent acts like a conventional pawl.
- the retainer is disengaged, the detent detaches from the mechanical lever and is forced into the arresting position.
- the two-part embodiment of the pawl also makes it possible to reduce the reaction time of the locking device.
- the two-part embodiment also has a particularly positive effect, if the electronic control of the electromagnet should have a malfunction (eg electromagnet defective).
- the catching device is then not ineffective, but it can still ensure sufficient securing of the user with the aid of the mechanical locking device.
- the proven safety of conventional safety gears is complemented by the option in a particularly advantageous manner, the speed at which the locking device is triggered to adjust individually and adapt to the specific needs of the user and the conditions of the respective climbing protection system.
- the safety gear increases the safety of the climbing protection system while offering a much greater ease of use than conventional safety gear.
- the two-part embodiment is here understood by the first unlocked position, that position in which the locking lug is held by the holding means on the lever. In the second, locking position, however, the holding device has released the locking lug, so that it has detached from the lever. If the electronics fails and therefore the mechanical lever together with the latch like a conventional, one-piece pawl pivoted against the catching latches of the guide rail and locked to them, so the latch is in the arresting position, although the holding device has not solved and the latch still restrains. Normally, however, the electronics react faster than the mechanics, so that, for the sake of simplicity, this linguistic incorrectness can be accepted.
- Speed determining a generator which is driven by a wheel or a roller, wherein the wheel is pressed against the guide rail of the climbing protection device, so that it has constant contact with the running surface of the guide rail.
- the electrical energy which is generated by the generator during the movement of the rotor on the rail is also preferably used to supply the electronic control and the electromagnet with electrical energy.
- the electrical energy generated by the generator may be stored in capacitors to provide the controller with sufficient energy to energize the electromagnet.
- the electrical energy supplied by the generator alone may be sufficient to power the control system and the electromagnet. As a result, the safety gear is completely self-sufficient and independent with respect to the power supply.
- the electronic device for speed determination can also have other optical or electronic elements.
- the speed of the rotor via an optical sensor (eg speckle sensor) based on the optical River determines.
- the speed can also be determined by capacitive or inductive methods.
- the speed threshold is selected to be above the speed that the runner reaches when the user is using the climbing device normally.
- the locking device according to the invention can react earlier in a crash than in the prior art.
- the threshold value of the speed can be selected to correspond to a drop height of less than or equal to 50 cm, preferably less than or equal to 10 cm. In practice, it is advantageous to choose this threshold in a range between 0.7 and 1.5 m / s, more preferably 0.8 to 1.2 m / s.
- the locking device is mounted on the rotor so that manipulation of the movable stop element is prevented by the user when the rotor is mounted on the rail.
- the user can not prevent the stop member from blocking the runner on the rail in the event of a user crash.

- the locking device 30 comprises a bolt 32 which is slidably mounted in an opening 34 of the rotor 10.
- the bolt 32 may be in two positions. In a first position, the bolt 32 is retracted as far as possible into the housing 20 of the rotor 10 and allows the free movement of the rotor 10 along the rail 12.
- the rail 12 has at intervals catching latches 106 in the form of openings or latches 107 in the form of Notches (Fig. 2). In the second position, the bolt 32 protrudes so far beyond the rear side 16 of the rotor 10 that it engages in one of the catching latches 106 of the rail 12 and thus blocks the movement of the rotor 10 along the rail 12.
- a stop 38 is provided in order to limit the sliding of the bolt 32 in the direction of the rail 12.
- the bolt 32 is stressed by means of a compression spring 40 in the direction of the second, blocking position.
- the housing 20 of the rotor 10 is designed so that it covers the entire locking device 30, and thus the user from the front side 14 of the rotor 10 has no access to the locking device 30. This avoids that the user neither intentionally can unintentionally engage in the locking device 30.
- the fact that the bolt 32 protrudes from the back 16 of the rotor 10 is not a disadvantage since the back 16 is not accessible to the user when the runner 10 is seated on the rail 12.
- the locking device 30 is triggered when the sliding speed of the rotor 10 in the rail 12 exceeds a predetermined speed, which is representative of a crash situation.

- the electric generator 60 has a rotor axis that is driven by a friction wheel 62 or a roller that rolls on the rail 12.
- the friction wheel 62 may be mounted directly on the axis of the rotor of the generator 60 or transmit rotation to it via a motion transmission system.
- the voltage or frequency of the electrical signal generated by the generator 60 increases with the rotational speed of the rotor.
- An electronic controller 70 is connected to the generator 60 and receives its voltage or frequency signal.
- the speed threshold may be fixed or adjustable via a potentiometer, for example.
- the electronic controller 70 may be an electronic card or printed circuit that is well known to those skilled in the art. For example, if the variable characteristic of the speed is the voltage supplied by the generator 60, the comparison can be made by means of an electronic circuit.
- the electrical energy generated by the generator 60 upon movement of the rotor 10 on the rail 12 may be used to provide electrical power to the electronic controller 70 and the electromagnet 46.
- the electrical energy generated by the generator 60 may be stored in capacitors to provide the controller 70 with sufficient energy to energize the solenoid 46.
- the electrical energy supplied by the generator 60 alone may be sufficient to power the control system 70 and the electromagnet 46.
- the safety gear 10 is completely self-sufficient and independent with respect to the power supply.
- the user can then reset the bolt 32 by hand in the non-blocking position, for example, by the rear part of the Rail 12 presses on the end of the bolt 32 until the pin 42 engages in recess 44 of the bolt 32 again.
- Safety gear 10 is also guided on the guide rail 12.
- the guide rail 12 is a C-profile, wherein the opening edges of the C-profile serve as guide flanges.
- the rotor 10 has guide grooves 82 on both sides, which receive the guide flanges of the guide rail 12.
- In the guide grooves 82 are guide rollers 84 to 89, which roll on the outside and the inside of the guide flanges.
- the guide rollers 84 to 89 are preferably made of plastic or elastomer or coated with such a material to limit the noise during sliding of the rotor 10 on rail 12.
- the rollers 84 to 89 also provide for the positioning of the rotor 10 in relation to the rail 12 and consequently the friction wheel 62 on the rail 12.
- the stopper 108 may be solid and integral with the rotor 10. It can also be adjustable so that the height of the projection of the locking lug 102 of the pawl 100 on the rear wall 16 of the rotor 10 is adjustable. As a result, the rotor 10 can be adapted to different rails 12 with a greater or lesser spacing of the catching latches 106, 107 from the rear side 16 of the rotor 10.
- the stop 108 is, for example, a screw screwed into the rotor 10 without a head.
- the pawl 100 is claimed in the direction of the second position.
- the stress is preferably an elastic loading element, for example a spring 110 between the runner 10 and the pawl 100.
- the stress on the pawl 100 towards the bottom of the rail 12 can only be achieved by gravity acting on the pawl 100 acts.
- the safety gear 10 has a holding device which holds the pawl 100 in the first position during normal operation and which can be disengaged to allow movement of the pawl 100 to the second position.
- the holding device may be identical to that of the first embodiment, except that the recess 44 is provided in the pawl 100.
- the retainer is disengaged by turning on the solenoid 112 to produce a magnetic force that opposes the magnetic adhesion of the permanent magnet 114 and is sufficient to release the permanent magnet 114 from the corresponding surface of the solenoid 112.
- the biased pawl 100 is pivoted by the spring 110 into the second position, so that the detent 102 of the pawl 100 engages in one of the catching latches 106, 107 of the guide rail 12 and thus prevents the downward movement of the rotor 10 on the rail 12.
- the pivoting of the pawl 100 to the second position results from the stress of the spring 110 or any other load means mentioned above, but the swing speed can be advantageously enhanced by magnetically repelling the permanent magnet 114 from the solenoid 112 to provide faster blocking of the rotor 10 To ensure rail 12.
- the locking device 30 is activated according to this second embodiment, when the Sliding speed of the rotor 10 on the rail 12 exceeds a predetermined threshold speed, which is representative of a crash situation exceeds.
- the electronic controller 70 and the electric generator 60 are housed in the same housing 72.
- the housing 72 also contains the friction wheel 62, which is intended to roll on the front side of the rail 12, and two further wheels or rollers 64 and 66.
- the friction wheel 62 rotates the rotor of the electric generator 60, wherein the friction wheel 62 drives the roller 64, which in turn drives the roller 66 on the rotor axis of the electric generator 60.
- a counter-roller 68 is provided to the contact of the
- Friction wheel 62 to ensure with the rail 12.
- the counter-roller 68 should roll on the front wall of the rail 12 with respect to the friction wheel 62. It is preferable to provide that the front wall of the rail 12 is clamped elastically between the friction wheel 62 and the counter roller 68.
- the counter-roller 68 can be elastically stressed against the friction wheel 62.
- the counter-roller 68 may be rotatably mounted on the end of an arm 74 pivotally mounted on the housing 72 relative to an axis 76. The end of the arm 74, which carries the counter-roller 68, is stressed in the direction of the friction wheel 62 by a compression spring 78, which is shown only in FIG.
- the pawl 100 is arranged on the rotor so that manual intervention by the user is avoided.
- the pawl 100 can be arranged so that it is avoided that the user can block the pawl 100 by using a tool, such as a screwdriver between the pawl 100 and rotor 10, to prevent movement in the direction of rail 12.
- the solenoid 112 is housed in a housing 10 mounted on rotor 10. More specifically, this housing 20 is mounted on the front side 14 of the rotor 10 over the aperture 34 in which the pawl 100 is located. In the example given, the housing 20 only partially covers the opening 34, namely the lower part with the latching lug 102 of the pawl 100, which lies opposite its pivot axis 120.
- the housing 20 prevents the user from intentionally blocking the pawl 100 from engaging in the catch latches 106, 107 at the bottom of the rail 12 by manual engagement with the free portion of the pawl 100 or by inserting a tool such as a screwdriver into the aperture 34 between the free end of the pawl 100 and the rotor 10 can hold.
- a tool such as a screwdriver
- the user can not grip or block the pawl 100, since this does not protrude beyond the front 14 and the clearance between the side edges of the pawl 100 and the side walls of the opening 34 is sufficiently low to prevent the user from inserting a finger or a tool, such as a screwdriver.
- the locking device 30 has been triggered and blocked the free movement of the rotor 10 in the rail 12, it is envisaged that the user can bring the pawl 100 back into the first position to continue the descent or rise of the climbing device , In the example shown, the notches or latches 107 of the rail 12 during an upward movement of the rotor 10 to a sufficient pivotal movement of the pawl 100 toward the first position, so that the permanent magnet 114 due to the fact that the solenoid 112 is no longer energized again magnetically adhered to the corresponding surface of the electromagnet 112. Once the pawl 100 is in the first position, the safety gear 10 is ready for personal fall protection again.
- Figure 4 shows a three-dimensional view of the safety gear 10 according to this second embodiment. For clarity, the attachment point 18 is not shown.
- Catching device 10 a second, mechanical locking device to block the sliding of the rotor 10 in the rail 12 in the fall of the user, said second locking device of the prior art, as described for example in DE-U-295 01 716 corresponds.
- the second locking means comprises a further pawl, which can be pivoted from a first position, in which it does not hinder the movement of the rotor 10 on the rail 12 in downward movement, in a second position in which they the movement of the rotor 10 on the rail 12 blocked in the downward direction.
- the stopper 18 is mounted on this second pawl.
- the transition of the second pawl from the first position to the second is triggered by the downward change of direction due to a train that the user exerts on the second pawl via a connecting means with which it is attached to the attachment point 18.
- the second locking device operates independently of the first locking device 30 according to the first or second embodiment. Consequently, if the one locking device is defective, the second one works Farther. In particular, the second conventional locking device continues to provide fall protection when the first locking device should not operate, for example due to a failure of the electrical generator 60 or the control system 70.
- the first locking means 30 according to the first or second embodiment and the second locking means according to the prior art can be successively mounted longitudinally on the same slider 10.
- the safety gear 10 has a pawl, which is designed in two parts, in contrast to the pawl 100 of the second embodiment.
- This two-part pawl is composed of a mechanical lever 104 and a detent 102 which are rotatably mounted independently on the same axis 120.
- the mechanical lever 104 has the attachment point 18, to which the user is attached via a connecting means.
- the holding device of the locking device 30 serves to hold the latching lug 102 on the mechanical lever 104.
- the holding device may have an electromagnet 112, which is enabled by current supply as in the second embodiment.
- the solenoid 112 is located on the detent 102, while the permanent magnet 114 is mounted opposite to the lever 104, or vice versa.
- the lever 104 has a bearing surface 124 that is in contact with a surface 126 of the latch 102 to transmit shear stresses of the mechanical lever 104 to the latch 102 and to prevent them from passing over the permanent magnet 114 and the corresponding surface of the electromagnet 112 take place.
- the detent 102 is mounted on the slider 10 so as to prevent manipulation by the user.
- the portion of the mechanical lever 104 towards the upper end of the rail 12 forms a fork at the level of the axis 120.
- the portion of the detent 102 toward the upper portion of the rail 12 is mounted between the arms of the mechanical lever 104, which form the aforementioned fork.
- the detent 102 does not protrude beyond the front surface of the mechanical lever 104.
- the electronic controller 70 causes the locking device 30 to trip when the sliding speed of the runner 10 on the rail 12 exceeds a threshold above which the user is assumed to be in a crash situation located.
- the electronic control system 70 and the measurement of the sliding speed of the rotor 10 on the rail 12 by means of an electric generator 60 can be carried out in an identical manner as described with reference to the second embodiment.
- the housing 72 containing these components is attached to the upper end of the rotor 10, which facilitates the connections of the electronic controller 70 to the solenoid 112. Alternatively, it may be attached to the lower end as shown for the second embodiment.
- the disengagement of the holding device causes the locking lug 102 of the mechanical lever 104, as shown in Figure 8, is released.
- the latch 102 is stressed by the spring 110 towards the bottom of the rail 12 and engages the catch latches 106, 107 at the bottom of the rail 12 to block the downward movement of the rotor 10 on the rail 12.
- the upward movement of the rotor 10 on the rail 12 is still possible in this situation.
- the safety gear 10 is used as follows.
- the detent 102 is fixedly connected to the lever 104 via the holding device.
- the user uses the safety gear 10 in a climbing system, he exerts a rearward or upward tensile load on the anchorage point 18 so that the two-piece pawl is kept away from the area of the catching latches 106, 107 at the bottom of the rail 12.
- This train may be manual or caused by a connection between the user and the attachment point 18. This case is illustrated in FIG.
- the electronic controller 70 disengages the restraint system prior to the two-piece pawl in the conventional manner, ie under the influence of the downward pull on the anchor point 18, in FIG the catch latches 106, 107 of the rail 12 is pressed.
- the holding device is disengaged, the detent 102 is released from the lever 104 and under the influence of the spring 110 in the direction of the catching latches 106, 107 of the rail 12 claimed.
- the speed threshold set to the electronic controller 70 must be appropriately selected. FIG.
- the safety gear 10 stops the user's fall, wherein the train is still directed towards the rear on the stop point, while the detent 102, which is no longer connected to the lever 104, is already inserted into the safety catch 106, 107 engages the bottom of the rail 12.
- the safety gear 10 remains effective also in the case where the user deliberately pulls the stopper point 18 rearwardly or upwardly to prevent the pawl 102 from engaging in the catching latches 106, 107 of the rail 12.
- the retainer is released and the detent 102 is forced into the catch latches 106, 107 of the rail 12 to prevent the movement of the rotor 10 on the rail 12 despite the user's pulling motion to block the stop 18.
- the re-engagement of the holding device takes place in this
- Embodiment automatically in that the mechanical lever 104 is pivoted in the event of a crash shortly after the release of the holding device also due to the weight of the user in the second position and thereby again in contact with the locking lug 102nd is brought.
- the permanent magnet 114 then adheres magnetically to the corresponding surface of the electromagnet 112, because the solenoid 112 is already de-energized at the moment. Because, since the rotor 10 is again at standstill at this time, its speed is therefore below the comparison threshold, the solenoid 112 has been set by the electronic controller 70 de-energized.
- Prevent holding device for example, if the generator 60 or the control system 70 would be defective, the locking lug 102 would due to the pulling movement down, which is exerted by the weight of the user on the attachment point 18 and thus on the lever 104, still forced into the catch pawls 106, 107 at the bottom of the rail 12 to press.
- locking means 30 also blocks runner 10 on rail 12, in a manner known in the art.
- Figures 9 to 12 show the safety gear 10 in a fifth
- buffers 90 and 92 are attached. These buffers absorb shocks and mechanical oscillations between the bottom of the lateral grooves of the rail 12 and the rotor 10 during movements on the rail 12 and limit the noise caused by the movement of the rotor 10.
- the buffers 90, 92 can also be used in the above embodiments.
- the pawl is in turn made in two parts, in which case the latching nose 102 is rotatably mounted with two fork-shaped arms on the axis 120.
- the lever 104 is mounted between the arms of the fork of the latch 102.
- the reverse configuration as described in the fourth embodiment is also applicable.
- the spring 110 does not bear the locking lug 102 directly in the direction
- Reaction speed of the locking device 30 is accelerated in certain cases. Because if in the event of a user crash, the movements of the detent 102 and the mechanical lever 104 overlap, the detent 102 is directly loaded by the spring 130 and simultaneously claimed indirectly by the spring 110. Thus, the time required to pivot the latch 102 from the first to the second position, so the reaction time of the locking device 30 is reduced.
- the latch 102 acts on the latch 102 or blocks it with a tool, similar to those described with reference to the fourth embodiment. It is also the panel 128 may be provided to prevent any insertion of a tool or a finger of the user, should the game between the part of the latch 102, which faces the lower part of the rail 12, and the opposite edge of the opening 34 of the rotor 10 be big enough.
- the cladding is shown schematically only in Figures 10 to 12.
- the housing 72 (not shown) including generator 60 and friction wheel 62 may be mounted on the front side 14 of the rotor 10 in a recess 73.
- Embodiment is identical to the operation of the fourth embodiment except for the above-mentioned role of the springs 110 and 130.
- this invention is not limited to the described and illustrated embodiments, but may have many variants that are accessible to the skilled person.
- the electronic controller 70 may be arranged to set, in addition to the speed, the direction of movement of the runner 10 on the rail 12 so as not to cause disengagement of the holding system when the speed threshold is exceeded during ascent. This will prevent the slider 10 from jamming on the rail 12 when the slider 10 is facing up, i.e., the slider 10 is in the up position. in a direction that does not correspond to a crash. However, it is easier not to make this determination and always trigger the locking device 30 as soon as the speed threshold is exceeded, no matter in which direction the rotor 10 slides. Normally, this speed threshold is not reached when the user climbs up a climbing system and so in this case does not lead to a blockage of the rotor 10 on the rail 12. Due to their bevel, the locking lug 102, the latches 106, 107 normally run over anyway.
- the speed is measured by means of an electrical generator 60.
- an electrical generator 60 can be resorted to an inductive, capacitive or optical speed sensor, which can cooperate with the catching latches 106, 107 at the bottom of the rail 12 or other elements which are built into the rail 12, for this purpose.
- an electric generator 60 is advantageous because it can also be used to generate the required electrical energy alone for the operation of the safety gear 10.
- the electronic controller 70 is provided to activate the locking device 30 when the speed threshold from the runner 10 is exceeded. Of course, the controller 70 may also do so can be used to activate the locking device 30 already when the speed limit is reached.
