Description

The invention relates to a barrier, in particular for retaining liquids or granules. For protection against leaking liquids, granules, water ingress in underground garages and other applications automatically closing barriers are common. From the EP 1 524 369 A2 a barrier is known, comprising a barrier body with a sealing element for horizontal sealing of the barrier body against a substrate, at least one wedge seal arranged on the barrier body for vertical sealing of the barrier body against a barrier receptacle, at least one barrier receptacle with a sealing seat for receiving the wedge seal and at least a pivotally connecting the barrier body with a selectable fixed point pivotally connected about a horizontal axis. Such a barrier requires, when the barrier body is pivoted upward, a very large clearance, which is not available in many applications or should not be used for aesthetic reasons. Pull-up barriers limit the remaining clearance. Retractable barriers in the ground cause considerable installation effort and in many cases, for example inside buildings, are limited by the thickness of ceilings between floors.

From the DE 4008813 A1 is known a rotatable about a vertical axis barrier with a base seal, a barrier rotary receptacle and a pivot, which allows rotating a barrier body about a vertical axis known. The gennante barrier has the disadvantage that to close the barrier small obstacles on the road can not be overcome.

The invention is therefore based on the object to provide an improved barrier that affects the clear height and the clear width at their installation as little as possible.

The object is achieved by a barrier with the features of claim 1.

Advantageous embodiments of the invention are the subject of the dependent claims.

A barrier according to the invention comprises a barrier body, a base seal for sealing the barrier body against a substrate, a barrier receptacle, a barrier rotary receptacle, at least one barrier receiving seal for substantially vertically sealing the barrier body against the barrier receptacle, at least one barrier rotational sealing gasket for substantially vertically sealing the barrier body against the barrier rotational receptacle and at least one pivotally connecting the barrier body at a lateral first end about a substantially vertical axis with the barrier rotary receptacle directly or indirectly. The barrier body is rotatable in a rotation range from a horizontal closing position to a horizontal opening position. In the horizontal closed position, there is a second end of the barrier body opposite the first end in the barrier receptacle, in particular such that the barrier body abuts there. In the horizontal opening position, the barrier body is rotated out of the barrier receptacle. The base seal can be arranged on the barrier body or on the ground. The barrier receptacle and the barrier rotary receptacle are arranged laterally of the barrier body in the horizontal closed position so that they can not be enveloped by liquids or granules, for example screwed to a side wall and sealed against it. The barrier receiving seal may be attached to the barrier body or to the barrier receptacle. Likewise, the barrier rotary receiving seal may be attached to the barrier body or to the barrier rotary receptacle. The orientation of the axis of the rotary joint relative to the barrier rotary receptacle is preferably adjustable, for example by the rotary joint is fastened by means of screws in slots on the barrier rotary receptacle. As a barrier receiving seal, barrier rotary receiving seal and in particular as a base seal are preferably closed-cell seals made of EPDM (ethylene-propylene-diene rubber) are used in the pores no liquids can penetrate from the outside. The height of the barrier body is regularly lower than the ceiling height at the location of the horizontal closed position, for example, a passage. Such a barrier can be used in limited space by the barrier body in the horizontal opening position abuts against the wall to which the barrier rotary receptacle is attached. This neither reduces the clear height of the passage, nor is the clear width significantly reduced. Likewise, there is no need for laborious entry of the barrier or parts thereof into the ground under the passage.

The first end of the barrier body is pivotally mounted to the pivot by at least one at least four-link linkage, wherein pivotal movement of the barrier body between an upper position and a lower position includes at least one movement component in the direction of the axis of the pivot. In particular, two congruent four-membered coupling gears are provided in parallel. The coupling gears are preferably parallelogram-shaped, but may also be trapezoidal. Regularly, the pivotal movement of the barrier body in addition to the mostly vertical component of movement in the direction of the axis of the rotary joint on a substantially horizontal component of movement in the direction of the second end of the barrier body. Typically, the barrier body will remain in the horizontal open position and the upper position when no liquids or granules are to be blocked. To close the barrier of the barrier body is first rotated to the horizontal closed position, while it remains in the upper position during the rotation in order to pass over obstacles if necessary. Arrived in the horizontal closed position, the barrier body is lowered to the lower position to seal against the ground. By the barrier body is pushed by means of the horizontal movement component in the direction of the barrier receptacle, it can, with appropriate design of the barrier receptacle, both in the direction in which he strikes the barrier receptacle, as well as in the opposite direction, the pressure of existing liquids or granules. For a higher stability, two congruent coupling gears can be provided, whose joints are aligned with each other and their members are synchronously movable are. The fact that the barrier is opened and closed only in a raised state, it is possible to overcome smaller obstacles on the road, especially ice, snow or stones when opening and closing. The fact that the barrier in the raised state in the direction of the wall on which the hinge is arranged, is shifted, it is also possible, when opening and closing smaller obstacles on the wall on which the barrier receptacle is arranged, in particular sockets, switches or Cable channels, overcome. It is also possible to provide an optional pulse tensioner for raising and / or lowering the barrier.

Preferably, the barrier body has substantially the shape of a cuboid whose smallest surfaces lie at the first and at the second end and whose largest surfaces are oriented substantially vertically. However, the barrier body may also have a variety of other shapes. In particular, he may, if in his swing range stairs, sections have on its underside a complementary to these stairs shape. The same applies to all other types of immovable obstacles, such as inclined surfaces and the like. Ä. Again, the underside of the barrier body may have a shape adapted to the obstacle profile and thus seal against this obstacle. In order to protect inlets, draft and the like located near the barrier, the barrier body may have corresponding protruding attachments which seal against the ground around the inlet or draft when the barrier body is rotated to the horizontal closed position and pivoted to the lower position is. Furthermore, the barrier body can have one or more attachment elements, in particular vertically upwards, which facilitate manual rotation from the horizontal closed position into the horizontal opening position.

The barrier receptacle and / or the barrier rotary receptacle are designed as substantially perpendicular U-profiles in which the barrier body is securely held in the horizontal closed position and the lower position. With this form of barrier recording, the barrier body, when using the horizontal movement component is pushed in the direction of the barrier receptacle, easily in the direction in which he strikes the barrier receptacle, as well as in the opposite direction to withstand the pressure of existing liquids or granules. In addition, the shape of a U-profile of the barrier receptacle or the barrier rotary recording gives a high rigidity.

Preferably, a first flange of the U-profile on a side in the direction of the horizontal opening position is shorter than a second flange of the U-profile. In the case of the barrier receiving the second flange forms a stop, up to which the barrier body rotates in the horizontal closed position. The shorter, first flange is initially not in the way of turning the barrier body, but secures it against turning back, as soon as it has been pivoted to the lower position and thereby pushed through the horizontal movement component into the barrier receptacle. In the case of the barrier rotary receptacle, the shorter first flange allows a large angle of rotation of the barrier body. The barrier body may be sealed against both flanges of both the barrier receptacle and the barrier rotary receptacle with a barrier receiving seal and a barrier rotary receiving seal, respectively.

In a preferred embodiment, the barrier receptacle and / or the barrier rotary receptacle are designed such that at least one section of at least one of the U-profiles has a wedge-shaped web and at least one of the flanges in this section deviates from the vertical at this web, so that the U Profile tapers down in this section. The barrier body is formed at the end that is at least in the horizontal closed position and the lower position in the U-profile with the wedge-shaped web, complementary to the U-shaped profile wedge-shaped or provided with at least one body with a wedge-shaped sealing surface. In this way, the barrier body, when lowered to the lower position, does not have to be guided along the barrier receiving seal or the barrier rotary receiving seal, which would result in friction and wear on the seal. Instead, kick up Shortly before reaching the lower position virtually no friction and the barrier body sits in the lower position taut and without play, which ensures a high degree of tightness. In one-sided wedge shape of the U-profiles, the barrier rotational receptacle is in particular wedge-shaped on its side facing away from the horizontal opening position and the barrier receptacle on its side facing the horizontal opening position. The barrier body is formed wedge-shaped to match. As an alternative to the wedge shape of the U-profile, at least one of the flanges of a straight U-profile may also be provided with a wedge-shaped body arranged in the region of the barrier receiving seal or barrier rotary receiving seal.

In a preferred embodiment, a closing device is provided on the barrier, which rotates the barrier body by means of spring force of a first spring from the horizontal opening position to the horizontal closing position. The spring used for this purpose may be a torsion, bending, tension or gas spring. By using such a closing device can be dispensed with active components to be controlled for automatic closing of the barrier and thus the reliability can be increased. The locking device may be provided with a damping element for damping, in order not to endanger the safety of persons in the rotation range of the barrier body and to avoid a high pulse when the barrier body abuts against the barrier receptacle.

Preferably, the barrier body is detectable in the horizontal opening position by means of a holding device, which is in particular automatically triggered to trigger the process of automatically closing the barrier.

In this case, the holding device is preferably designed as an electro-adhesive magnet which only adheres to a ferromagnetic surface of the barrier body or a holding element arranged on the barrier body when current flows. The current flow can be interrupted in particular by a power failure, actuation of an emergency stop switch, by the triggering of a liquid detection sensor, fire alarm sensor or the like. It may be an audible and / or visual warning device be provided, which indicates the closing of the barrier or announces. For this ringing, horns, sirens, traffic lights, flashing lights and flashing lights come into consideration. Similarly, a time delay between the triggering event and the actual closing of the barrier may be provided to allow people in the area of rotation to leave it safely.

In a preferred embodiment, a spring accumulator is provided on the barrier receptacle which remains in a cocked position until the barrier body actuates a triggering mechanism during rotational movement into the horizontal closed position as it enters the barrier receptacle, causing a pulsatile movement of the spring accumulator into a relaxed position in that the spring accumulator exerts a force acting substantially vertically downwards on the second end of the barrier body. Furthermore, the spring accumulator from the relaxed position in the cocked position can be reset, in particular manually by means of a lever. With appropriate design of the barrier body this can be pressed down in this way from the upper position to the lower position. The manual reset prepares the spring accumulator for another closing process, in other words, it sets it in focus.

The spring accumulator is designed, in particular, as a first four-bar linkage with four links (referred to as spring-link links to distinguish similar links) whose first spring-loaded link is fixedly connected to a first carrier element fixed to the barrier receptacle or is formed by this carrier element or immovable relative to the barrier receptacle is. A first spring-loaded member engaging the second spring-loaded member is in the cocked position in a stop position in which it is held by a second spring, in particular a compression spring. The second spring is connected on the one hand to the first carrier element and on the other hand to the second spring-loaded member. From this stop position, the second spring-loaded member is rotatable to the relaxed position by being lifted above a first zero position beyond which the second spring relaxes it Position turns. This first zero position is typically characterized by a maximum bias of the second spring. The second spring storage member rotates via a third spring storage member acting on the first spring member fourth spring storage member so that it exerts a substantially vertically downward force acting on the second end of the barrier body, so pushes it down. In order to reduce friction and wear due to the horizontal movement component of the barrier body, the fourth spring memory member may be provided with a roll screw, in the top of a ball is arranged, with which the barrier body is pressed down and at the same time allows its low-friction sliding along the roller screw. The spring accumulator is reset by turning the second spring-loaded member in the stop position in the cocked position. For this purpose, the second spring-loaded member is provided in particular with a lever-like attachment, for example an extension beyond a pivot point between the first and the second spring-loaded member. The triggering mechanism is preferably designed as a two-armed lever with a force arm and a load arm, wherein the force arm is actuated by the barrier body upon its entry into the barrier receptacle during horizontal rotation. The load arm then moves the second spring storage member from the stop position over the first zero position, so that the spring accumulator moves in the relaxed position. The power arm may be provided at its end with a rotatable roller to reduce friction between the power arm and the barrier body.

In a preferred embodiment, a two-way tensioner is disposed at the first end of the barrier body which selectively pushes the first end of the barrier body to the upper or lower position, the two-way tensioner having a second zero position between the upper and lower positions and moving the two-way tensioner causes a change in the other position from one of the positions to about the second zero position. Such a two-way tensioner, taking into account the weight of the barrier body and possible buoyancy forces by pending liquids, etc., ensures that the barrier body, at least at its first End is either in the upper or in the lower position, that is in a defined state.

The second zero position is preferably passable from the upper position by lowering the second end of the barrier body. In other words, when the second end of the barrier body is lowered, for example by means of the spring accumulator, the force that occurs causes the two-way tensioner to cross the second zero position from its current position, in which it presses the first end into the upper position as a result he pushes down the first end.

The two-way tensioner is preferably formed so that a first link of the linkage is fixedly connected to the pivot joint, that a third link of the linkage is fixedly connected to the first end of the barrier body and that a second and a fourth link respectively the first and the third link wherein the second member comprises a two-way tensioning arm in the form of an extension beyond a two-way tensioner pivot located between the second and third links in the direction of the barrier body. A compression spring is on the one hand at a barrier body point, i. a fixed point on the barrier body, connected to the barrier body and, on the other hand, at an extension point to the two-way tensioner arm. The barrier body point, the extension point and the two way vise joint point are aligned in the second null position. The compression spring is biased maximum in the second zero position. An educated in this way Zweiwegspanner is particularly simple and inexpensive to implement.

Preferably, a locking device is provided at the second end of the barrier body, with which the barrier body can be pressed into the lower position and / or locked in the lower position to prevent inadvertent leaving the lower position of the barrier body, for example due to buoyancy and / or the barrier body to press down and if necessary to the barrier receiving seal.

The locking device preferably comprises a second four-bar linkage with four links (hereinafter referred to as locking links). A first locking member is immovable with respect to the barrier body. A second locking member engaging the first locking member has a locking load arm in the form of an extension extending beyond a first locking pivot point. The first locking hinge point connects the second locking member to a third locking member. The third locking member connects the second locking member with a fourth locking member engaging the first locking member. The fourth locking member has a locking arm in the form of an extension extending beyond a second locking pivot point. In a locking position of the locking device, the third locking member and the fourth locking member are parallel to each other. In an unlocked position, the latch load arm is inclined downwardly toward the second end of the barrier body. When moving from the unlocked position into the locking position, the locking load arm slides upwards on a guide arranged diagonally on the barrier receptacle. In this way, the second end of the barrier body is pressed sideways against the barrier receptacle at the latest when reaching the locking position. Due to the parallel position of the third and the fourth locking member in the locking position, the locking device is self-locking. The lock load arm can not be moved from this position. The locking position can only be left by actuating the locking arm. Unintentional opening of the barrier is thus almost impossible.

In a preferred embodiment, the two-way tensioning arm is connected to the locking arm by means of a cable such that movement of the first end of the barrier body to the lower position causes movement of the locking device from the unlocked position to the locking position. The locking arm moves by means of a tension spring or other spring from the locking position to the unlocking position, when the cable is relaxed. The cable can be guided over pulleys. In this way, the process of automatically closing the barrier is completed by an automatic lock without the need for manual intervention.

FIG. 1a shows a plan view of a barrier 1 with a barrier body 2 in a horizontal opening position and an upper position. The barrier 1 is arranged in a passage defined by two walls 55 or a passage. The barrier 1 has a barrier rotary receptacle 3 and a barrier receptacle 4, which are each attached to a wall 55 and sealed against it. In the barrier rotary receptacle 3, the barrier body 2 is rotatably arranged at a first end 5 about a substantially vertically oriented pivot 10. The connection between the first end 5 and the rotary joint takes place indirectly via two parallel and mutually congruent four-membered coupling gear 11, by means of which the barrier body 2 is arranged pivotably on the rotary joint 10. A pivoting movement of the barrier body 2 between an upper position and a lower position includes a component of movement in the direction of the axis of the pivot joint and a horizontal component of movement in the direction of a second end 6 of the barrier body 2. The coupling gear 11 are formed parallelogram. For sealing the barrier body 2 against the barrier rotary receptacle 3, a barrier rotary receiving seal 9 is provided on the barrier rotary receptacle 3. For sealing the barrier body 2 against the barrier receptacle 4, a barrier receiving seal 8 is provided on the barrier receptacle 4. The barrier receiving seal 8 and / or the barrier rotary receiving seal 9 are formed as closed-cell EPDM seals. Preferably, the barrier receiving seal 8 and / or the barrier rotary receiving seal 9 are slot-shaped, thus have an elongated, open at the ends cavity. The rotary joint 10 can be adjustably arranged on the barrier rotary receptacle 3, for example by means of screws in oblong holes. Between the wall 55 and the barrier body 2, a first spring 13, here a gas spring, arranged, which endeavors to turn the barrier body 2 in a horizontal closed position (see Figures 2 a, b to 4 a, b). In the horizontal opening position, in which the barrier body 2 stands by in standby, it is held by a holding device 12. The holding device 12 is designed as an electro-adhesion magnet, which adheres to a ferromagnetic surface of the barrier body 2 only when current flows. For this purpose, the barrier body (2) is itself formed from a ferromagnetic material, such as steel, or provided with a holding element made of a ferromagnetic material. The flow of current can be interrupted by a power failure, by pressing an emergency stop button, by the triggering of a liquid-level sensor or a fire alarm sensor (not shown). An audible and visual warning device (horn and beacon) is provided which indicates and announces the closing of the barrier 1 (not shown). The closing of the barrier 1 takes place with a time delay of, for example, 10 seconds after a triggering event. The barrier rotary receptacle 3 is formed in the present example in the form of an L-profile. The barrier receptacle 4 has the shape of a U-profile with a shorter first flange 45 and a longer second flange 46 (For details see FIG. 8 ).

FIG. 1b shows one too FIG. 1a A part of the barrier rotary receptacle 3 is shown cut to show the pivot 10 and the barrier body 2 and its first end 5, respectively.

FIG. 2a shows a plan view of the barrier FIG. 1a in a horizontal closed position and the upper position. The triggering event has already taken place. The holding device 12 has released the barrier body, the first spring 13 has rotated the barrier body 2 in the horizontal closed position past the first flange 45 until it stops against the second flange 46.

FIG. 2b shows one too FIG. 2a belonging frontal view of the barrier 1. In this view, it is easy to see how the parallelogram coupling mechanism 11 is formed. The barrier body 2 is still in the upper position, seals So by means of a base gasket 7 not yet against a substrate. The barrier body 2 is held in the upper position by means of a two-way tensioner, not shown here, the structure and function of the FIGS. 6a and 6b and the associated figure descriptions becomes clear.

In Figure 3a and 3b is pressed in a next step of the closing operation of the barrier body 2 at its second end 6 by means of a spring accumulator 14, not shown here down, the structure and function of the FIGS. 5a and 5b becomes clear. Due to elasticity and play, the barrier body 2 does not immediately follow this downward movement also at its first end 5, so that the barrier body 2 tilts slightly during depression, as in FIG FIG. 3b for clarity is shown slightly overdrawn. Due to the depression of the second end 6 of the in the FIGS. 6a and 6b described in detail two-way tensioner a second zero position and thus also pushes the first end 5 of the barrier body 6 down, resulting in the in the FIGS. 4a and 4b shown situation leads.

In the FIGS. 4a and 4b the barrier body 2 is pivoted by means of the linkage 11 in a lower position in which it seals with its base seal 7 against the ground. As a result of the pivoting movement of the barrier body 2 has moved not only down but also sideways in the direction of the barrier receptacle 4, in which he is now so deeply inserted that he no longer, for example due to pressure of upcoming liquids or granules on the shorter first flange 45th can be turned over from the horizontal closed position. At least now seals the barrier body 2 against the barrier receptacle 4 and the barrier rotary receptacle 3, for example by the barrier receptacle 4 and / or the second end 6 of the barrier body 2 is designed as in the FIGS. 8 to 10 described.

FIG. 5a shows a side view of a spring accumulator 14 in a cocked position. The spring accumulator is used for automatically depressing the second end 6 of the barrier body 2 as soon as it is within the barrier receptacle 4 is located. The spring accumulator is designed as a first four-bar linkage with four spring storage elements 15, 16, 19, 20. A first spring-loaded member 15 is formed by a first carrier element, which is immovably or directly attached to the barrier receptacle 4. An attacking on the first spring member 15 second spring member 16 is in the cocked position in a stop position in which it is held by a second spring 17, here a compression spring. The second spring 17 is connected on the one hand to the first carrier element, ie the first spring-loaded member 15 and on the other hand to the second spring-loaded member. From this stop position, the second spring storage member 16 is rotatable in a relaxed position by being lifted over a first zero position 18, which is indicated here by a dashed line, away. Beyond the first zero position, the second spring 17 rotates the second spring-loaded member 16 in the relaxed position, the in FIG. 5b is shown. The first zero position 18 is typically characterized by a maximum bias of the second spring 17. The second spring-loaded member 16 rotates via a third spring-loaded member 19 acting on the first spring member 15 fourth spring member 20 so that it exerts a substantially vertically downwardly acting force on the second end 6 of the barrier body 2, so pushes it down, resulting in the in the FIGS. 3a and 3b shown situation leads. In order to reduce friction and wear due to the horizontal movement component of the barrier body 2, the fourth spring-loaded member 20 is provided with a roll screw 23, in the tip of a ball is arranged, with which the barrier body 2 is pressed down. The lifting of the second spring storage member 16 via the first zero position 18 by means of a trigger mechanism, which is designed as a two-armed lever with a power arm 21 and a load arm 22. The power arm 21 is actuated by the barrier body 2 as it enters the barrier receptacle 4 upon rotation to the horizontal closed position. The load arm 22 then moves the second spring member 16 from the stop position over the first zero position 18 away, so that the spring 14 moves to the relaxed position. The power arm 21 is provided at its end with a rotatable roller 24 to reduce friction between the power arm 21 and the barrier body 2. From the relaxed position can be the spring store 14 by turning the second spring-loaded member 16 in the stop position in the cocked position back. For this purpose, the second spring member 16 is provided with a lever-like extension beyond a hinge point between the second spring member 16 and the third spring member 19, to facilitate handling.

FIG. 6a shows a frontal view of the first end 5 of the barrier body 2 with a two-way tensioner in an upper position. The two-way tensioner uses the links 25 to 28 of the linkage 11, which serves to pivot the barrier body 2 between the upper position and the lower position. A first member 25 of the linkage 11 is fixedly connected to the rotary joint 10 or is formed of a rotatable part of the rotary joint 10. A third member 27 of the linkage 10 is formed by the first end 5 of the barrier body 2. A second member 26 and a fourth member 28 respectively connect the first member 25 with the third member 27. The first member 25 is the third member 27 and the second member 26 of the fourth member 28 in parallel. In fact, for reasons of stability, two second members 26 and two fourth members 28 are used on both sides of the barrier body 2, which are congruent with each other, whose joints are aligned with each other and move synchronously, so that one could speak of two coupling gears 11 ,

The second member 26 has a two-way tensioning arm 29 in the form of an extension beyond a two-way tensioner pivot point 30 located between the second member 26 and the third member 27 in the direction of the barrier body 2. A compression spring 31 is connected on the one hand to a barrier body point 32, ie a fixed point on the barrier body 2, to the barrier body 2 and on the other hand to an extension point 33 with the two-way tensioning force arm 29. The barrier body point 32, the extension point 33 and the two way tensioner pivot point 30 are in a second zero position in alignment. The compression spring 31 is maximally biased in the second zero position. In FIG. 6a the two-way tensioning force arm 29 is in the upper position. Moving the Zweiwegspannerkraftarmes 29 against the force of the compression spring 31 via the second zero position causes the compression spring 31 presses it in the lower position, so that the in FIG. 6b situation occurs. The same applies to an opposite movement from the lower position to the upper position. The bias of the compression spring 31 in the upper position and its arrangement is chosen so that the weight of the barrier body 2 is not sufficient for exceeding the second zero position, but the additional depression of the second end 6 of the barrier body 2 by the spring 14 and the occurring , in FIG. 3b shown tilting of the barrier body ensures that this second zero position is exceeded.

The provision of the Zweiwegspannerkraftarmes 29 from the lower to the upper position can be done manually as soon as the second end 6 of the barrier body 2 is no longer pressed down due to restoring the spring accumulator 14 in the cocked position.

On Zweiwegspannerkraftarm 29 a cable 34 is further arranged, which, guided over at least one guide roller 35 and passed here inside the formed as a hollow cuboid barrier body 2, attracted when changing to the lower position and is reduced when changing back to the upper position. This cable 34 is used to operate in the FIGS. 7a and 7b explained locking device.

Figure 7a shows a front view of the second end 6 of the barrier body 2 with a locking device in an unlocked position. The locking device comprises a second four-bar linkage with four locking members 37, 38, 41, 43. A first locking member 37 is immovable relative to the barrier body 2, ie indirectly or directly connected thereto. A second locking member 38 engaging the first locking member 37 has a locking load arm 39 in the form of an extension extending beyond a first locking hinge point 40. The first locking hinge point 40 connects the second locking member 38 to a third locking member 43. The third locking member 43 connects the second locking member 38 with a fourth locking member 41 engaging the first locking member 37. The fourth locking member 41 has a locking arm 42 in the form of an extension extending beyond a second locking pivot connecting the third locking member 43 and the fourth locking member 41. The cable 34 coming from the two-way tensioner engages the locking arm 42 and acts against a tension spring 44 which connects the locking arm 42 to a point on the first locking member 37 and tends to hold the locking arm 42 so that the locking device remains in the unlocked position What is the case as long as the cable 34 is not tightened as a result of adjusting the two-way tensioner in the lower position. In the unlocked position, the lock load arm 39 is inclined downwardly so as not to interfere with the rotational movement between the horizontal close position and the horizontal open position.

If the Verriegelerungsungskraftarm 42 pulled by means of the cable 34 by adjusting the two-way clamp in the lower position down, resulting in the locking device in FIG. 7b shown situation. The locking arm 42 moves down until the fourth locking member 41 is approximately vertical. In this case, the third locking member 43 and thus also the second locking member 38 is moved so that the third locking member 43 is parallel to the fourth 41 locking member, ie, the first locking joint point 40 is located between two further locking joint points. The second locking member 38 and thus the Verriegelungslastarm 39 are approximately horizontal. In this locking position, the locking device is self-locking by the parallel position of the third 43 and the fourth locking member 44 and the force exercisable by the Verriegelungslastarm 39 only in the orthogonal direction to this parallel position. The lock load arm 39 can not be moved from this position. The locking position can be left only by pressing the Verriegelungskraftarms 42 when pulled by lowering the cable 34 by means of the tension spring 44 back up becomes. The details of the lock with the lock load arm 39 will become apparent from the description FIG. 9 clear.

FIG. 8 shows a plan view of a barrier receptacle 4 with a wall attachment to a wall 55. The barrier receptacle 4 is formed as a U-profile with a shorter first flange 45 and a longer second flange 46, which are arranged on a web 47. The first flange 45 faces a side on which the barrier body 2 is in the horizontal opening position. The U-profile may be fastened directly to the wall 55 by means of at least one fastening screw 50, but here has two spacers 48 in order to gain some space behind the web 47, which space is required for the locking load arm, as described below FIG. 9 is shown. In order to avoid bypassing the barrier 1 by pending liquids between the barrier receptacle 4 and the wall 55, wall seals 49 are provided between the barrier receptacle 4 and the wall 55 and may be formed from a sealant. When the barrier body 2 is rotated into the horizontal closing position, the second end 6 of the barrier body 2 passes unhindered the first flange 45 and then abuts against the second flange 46. During the subsequent lowering from the upper position to the lower position, the second end 6 is pushed into the barrier receptacle 4 as a result of the horizontal movement component in the direction of the second end 6 of the barrier body 2 so that it comes to rest between the flanges 45, 46 and not more can be rotated out of the barrier receptacle 4 out.

FIG. 9 shows a frontal view of a wedge-shaped barrier receptacle 4 with a cross section of a second end 6 of a barrier body 2 with the locking load arm 39 in the locked position. The barrier receptacle 4 is formed from a U-profile, the web 47 is wedge-shaped at least in a portion of the U-profile. The flanges 45, 46 resting against the web 47 cause the barrier receptacle 4 to taper downwards in this section. The barrier body 2 is also formed wedge-shaped at its second end 6 complementary to the wedge-shaped barrier receptacle 4. When adjusting the locking device from the unlocked position to the locking position, the Verriegelungslastarm 39 slides from bottom to top along a guide 51 in the form of a wedge-shaped sheet and presses the second end 6 of the barrier body 2 down and to the side, due to the orientation of the guide 51 in the selected Example to the left, so that the barrier body seals with the barrier receiving seal 8 against the barrier receptacle 4 and with the base seal 7 against the ground. In the example shown, a breakout in the web 47 is provided, so that the locking load arm 39 when pivoting enough space on the back of the barrier receptacle 4 between the in FIG. 8 shown spacers 48 finds. The wedge shape allows a particularly dense and play-free fit of the barrier body 2 in the barrier receptacle 4. In a similar manner, the barrier rotary receptacle 3 may be formed wedge-shaped. Alternatively, only one of the flanges 45, 46 may be inclined. As an alternative to the wedge shape of the U-profile, at least one of the flanges 45, 46 of a straight U-profile may be provided with a wedge-shaped body arranged in the area of the barrier receiving seal 8 or barrier rotary receiving seal 9.

FIG. 10 shows a perspective view of the second end 6 of a barrier body 2, which is itself parallelepiped-shaped and two-sidedly provided with wedge-shaped bodies 52 which can seal against a formed in one of the above ways wedge-shaped barrier receptacle 4. It goes without saying that also only one side of the second end 6 of the barrier body 2 can be provided with such a wedge-shaped body 52. In the same way, the first end 5 of the barrier body 2 may be formed.

FIG. 11 shows a plan view of a barrier body 2 with a protruding attachment 54 for protection of a bottom inlet 53. The projecting attachment 54 is also provided with a base seal 7. Its shape depends on the shape of the bottom inlet 53 or an air shaft or the like.

FIG. 12 shows a frontal view of a barrier body 2 with an adapted to the shape of a staircase underside. Such a barrier body 2 is used when a solid obstacle, such as here a staircase, is located in a region of the horizontal closed position. The barrier body 2 is also provided here with respect to the stairs with a base seal 7. The figure is exemplary of all types of fixed obstacles, such as inclined planes or spherical shapes, etc., to which the barrier body 2 is respectively adapted.

An exemplary closing operation of the described barrier 1 proceeds as follows: A triggering event (power failure, actuation of an emergency stop switch, triggering of a liquid alarm sensor or a fire alarm sensor) activates a warning device (horn, beacon) and interrupts the current flow to the holding device 12 designed as an electro-adhesive magnet with a time delay releases the barrier body 2 located in the horizontal opening position and the upper position so as to rotate by the first spring to the horizontal closing position where its second end 6 abuts against the second flange 46 of the barrier receptacle 4 and the power arm 21 of the trigger mechanism actuated. As a result, moved load arm 22 lifts the second spring member 16 from its stop position on the second zero position 18, whereupon it is rotated by the second spring 17 in the relaxed position. As a result, the roll bolt 23 attached to the fourth spring storage member 20 pushes the second end 6 of the barrier body 2 downwardly in the lower position. The force thus acting in addition to the weight of the barrier body 2 is sufficient to move the Zweiwegspannerkraftarm 29 and thus the first end 5 of the barrier body 2 over the second zero position away in the lower position. In this case, the cable 34 is tightened, which pulls the Verriegelungsungskraftarm 42 down, whereupon the Verriegelungslastarm 39 slides along the guide 51 upwards in the locked position and the second end 6 of the barrier body 2 down and to the side in the direction of the base seal 7 and the barrier receiving seal 8 presses. The locking device is self-locking in the locking position. The second end 6 of the barrier body 2 is now wedged between the first flange 45 and the second flange 46 and can not be unscrewed from the horizontal closed position.

The described barrier 1 is set in readiness again by means of the following procedure. In case of elimination of the triggering event, the holding device is energized again. The second spring-loaded member 16 is rotated by means of an attached lever against the force of the second spring 17 in the direction of the relaxed position, whereupon the fourth spring-loaded member 20 pivots back with the roller screw 23 and no longer presses on the second end 6 of the barrier body. Since the power arm 21 is still actuated by the barrier body 2, the load arm 22 allows an adjustment of the second spring member 16 from the relaxed position only until shortly before the first zero position 18, where the second spring member 16 or the lever attached thereto, for example with a hook or a pawl is fixed. Subsequently, the two-way tensioning arm 29 and with it the first end 5 of the barrier body 2 is pulled up over the second zero position, whereby the cable 34 is released and consequently the Verriegelungsungskraftarm 42 is pulled by the tension spring 44 upwards, so that the Verriegelungslastarm 39 itself moved down to the unlocked position, whereupon the second end 6 of the barrier body 2 follows in the upper position. The now only on the second flange 46 abutting barrier body 2 is rotated against the force of the first spring 13 in the horizontal opening position, where it is held by the holding device 12. Now, the second spring member 16 can be moved over the first zero position 18 away to the cocked position, so that the barrier 1 is ready for a new closing operation.

The coupling gear 11 may be formed trapezoidal in order to achieve a different movement of the barrier body 2 during pivoting.

The barrier rotary receiving seal 9 may be disposed on the barrier rotary receptacle 3 or on the barrier body 2. Barrier pivot receiving seals 9 may be attached to the first flange 45 and / or the second flange 46 of the barrier rotating receptacle 3 be provided. Likewise, a respective barrier rotary receiving seal 9 can be provided both on the barrier rotary receptacle 3 and on the barrier body 2.

The barrier receiving seal 8 may be disposed on the barrier receptacle 4 or on the barrier body 2. Barrier receiving seals 8 may be provided on the first flange 45 and / or the second flange 46 of the barrier receptacle 4. Likewise, a barrier receiving seal 8 can be provided both at the barrier receptacle 4 and at the barrier body 2.

The barrier receiving seal, the barrier rotary receiving seal, and / or the base seal may be formed of materials other than EPDM.

The barrier receptacle 4 and the barrier rotary receptacle 3 may be formed with profile shapes deviating from the description.

All springs, compression springs, tension springs, in particular the first spring 13 and the second spring 17 may be provided with a damping. Among others, torsion, bending and gas springs are suitable.
