Description

Shut-off device and system

The invention relates to a blocking device for arrangement on a substrate, comprising an at least substantially tubular hollow body which defines a longitudinal direction of the blocking device, an actuating element which is arranged at a first free end of the hollow body and movable relative to the hollow body between a loose position and an anchoring position is, a mechanical anchoring mechanism, which is arranged in relation to the longitudinal direction opposite to the actuating element and comprises a movable locking element, and an actuating rod fixed to the actuating element, extending in the longitudinal direction and movably mounted, which is arranged in the hollow body and mechanically connected to the anchoring mechanism is coupled. The invention also relates to a shut-off system with such a shut-off device.

Shut-off devices of the type mentioned in the introduction belong in many different configurations to the state of the art. They serve to cordon off an area of the underground, usually a traffic area, temporarily or permanently, i.e. to protect it from being stepped on or driven on. For this purpose, one or more shut-off devices are arranged on the ground at an edge of the area to be protected.

Many barrier devices include an anchoring mechanism which serves to selectively anchor the barrier device to the ground. As a result of the anchoring, the shut-off device can neither be moved on the ground nor removed from the ground.

For example, CH 597433 A5 discloses a shut-off device designed as a traffic cone which comprises an anchoring mechanism for anchoring the traffic cone to a ground and an actuating element for operating the anchoring mechanism, which is arranged at a tip of the traffic cone.

If people and autonomously driving industrial trucks, for example forklifts, move together on a surface, for example on the floor of a warehouse or production hall, there is an increased risk of injury to the people. Occupational health and safety regulations are met by the fact that an area of the subsurface, in which a person moves, is not driven over by an industrial truck, that is, that the person and the industrial truck move or stay in spatially separate areas of the ground.

Modern industrial trucks are configured to detect, recognize and avoid certain shut-off devices by means of a camera, for example by means of ultrasound or electromagnetic radiation, i.e. to stop in front of them or to follow another trajectory. Accordingly, it is customary to cordon off an area of the ground on which a person to be protected is moving by arranging locking devices at an edge of the area and anchoring the locking devices arranged there to the ground and consequently to protect them from being driven on by the industrial trucks.

If anchored shut-off devices are loosened, relocated or removed by other people ignorantly or recklessly and unnoticed by the person in need of protection, the risk of injury to the person to be protected is increased.

The invention is therefore based on the object of creating a shut-off device for arrangement on a substrate, which improves occupational safety and is easy to handle.

Subjects of the invention are defined in the independent claims. The subclaims indicate advantageous developments of the respective subjects according to the invention.

The invention relates to a shut-off device for arrangement on a substrate, comprising an at least substantially tubular hollow body which defines a longitudinal direction of the shut-off device, an actuating element which is arranged at a first free end of the hollow body and, relative to the hollow body, between a loose position and an anchoring position is movable, a mechanical anchoring mechanism, which is arranged in relation to the longitudinal direction opposite to the actuating element and comprises a movable locking element, and an actuating rod fixed to the actuating element, extending in the longitudinal direction and movably mounted, which is arranged in the hollow body and with the anchoring mechanism is mechanically coupled. The shut-off device is thanks to that Anchoring mechanism can be anchored to the ground in order to block off an area of the ground temporarily or permanently, ie to protect it from being stepped on or driven on. The shut-off device is therefore an important means of occupational safety, especially when people and autonomously driving industrial trucks move together on a surface such as a warehouse or production hall.

According to the invention, the shut-off device comprises a locking plate, which is fixed relative to the tubular hollow body, and an actuating plate as the actuating element, the actuating plate in the loose position, the anchoring position and in every position between the loose position and the anchoring position parallel to the

Locking plate extends and the locking plate and the actuating plate each have at least one hole, which together form a pair of holes, and the at least one pair of holes is aligned exclusively in the anchoring position.

The at least one aligned pair of holes can be penetrated by a padlock of a person to be protected and allows the locking device to be locked when the actuation plate is in the anchoring position and the locking device is anchored to the ground. Accordingly, the anchoring of the locked shut-off device can only be released by the person to be protected. To do this, she opens the padlock and removes the grip of the padlock through the at least one aligned pair of holes, whereupon the actuating plate is moved into the loose position and the anchoring of the locking device is released. In this way, handling of the shut-off device is simple, the safety of the shut-off device is increased and, thanks to the increased safety of the shut-off device, occupational safety is improved.

The shut-off device preferably comprises a locking tube which extends in the longitudinal direction and is fixed to the locking plate, which is arranged in the hollow body, is fixed relative to the hollow body and in particular partially protrudes from the hollow body. The locking tube is used to fix the locking plate. If the locking tube protrudes from the hollow body, i.e. over the first free end of the hollow body, it can be reached easily without bending down, which makes handling of the shut-off device easier. In many embodiments, the hollow body has a conical envelope

Circumferential wall or a cylindrical jacket-shaped peripheral wall. As a hollow body A commercial traffic cone or pylon can be used with a cone-shaped peripheral wall. In this case, the actuating device is arranged at the tip of the traffic cone.

A blocking post comes into consideration as a blocking device with a cylindrical jacket-shaped circumferential wall. However, hollow bodies whose cross-sectional area, taken transversely to the longitudinal direction, have a contour that deviates from the circular shape, for example a polygonal contour, also fall under the scope of protection of the invention.

A length of the hollow body measured in the longitudinal direction can be in a range from 100 mm to 1100 mm and preferably be 300 mm, 500 mm, 700 mm or 900 mm. Commercially available traffic cones are available in the specified lengths.

Cleverly, the locking plate and the actuating plate each have a plurality of holes, in particular four holes each, which form a corresponding plurality of pairs of holes, in particular four pairs of holes. In this way, the shut-off device can be locked by means of a plurality of padlocks reaching through the aligned pairs of holes. For a rotary movement of the actuating plate, the pairs of holes are arranged at a distance from one another in a radial direction related to an axis of rotation. For a translational movement of the actuating plate, the pairs of holes are arranged at a distance from one another perpendicular to a translational direction. The pairs of holes are therefore arranged in the locking plate and in the actuating plate in such a way that alignment of holes in different pairs of holes, i.e. alignment of unpaired holes, is excluded.

In an advantageous embodiment, the locking plate and the actuating plate have an at least substantially circular outer contour and / or extend perpendicular to the longitudinal direction. In other words, the locking plate and the actuating plate are disc-shaped. Thanks to their direction of extension, they reduce the risk of injury, i.e. the risk of being staked or cut, in the event that a person falls on the barrier device located on the ground.

Ideally, the actuation plate can be rotated relative to the locking plate by an actuation angle which is in a range of 120 ° and 180 ° and is preferably 150 °. The operating angle is an obtuse angle and ensures a sufficient one Swivel angle for the locking element. In this embodiment, the actuating plate closes each hole in the locking plate in every position of the actuating plate relative to the locking plate that is different from the anchoring position, in particular completely or at least partially. As a result, a padlock can be attached to the operating plate or the locking plate only in the anchoring position of the operating plate or at least in a position close to the anchoring position of the operating plate. In this way it is ensured that a position of the actuating plate different from the anchoring position is not mistakenly held for the anchoring position by the person to be protected due to a padlock, whereby the security of the locking device is further increased. In another embodiment of the shut-off device, the actuating plate can be displaceable by an actuating distance relative to the locking plate.

Ideally, the at least one hole in the actuating plate and the at least one hole in the locking plate are each designed as a bore and each have a cylindrical shape with a cylinder axis which extends parallel to the longitudinal direction. When the actuating plate is rotated relative to the locking plate, the cylinder axis extends perpendicular to a direction of movement of the at least one hole. As a result, turning of the actuating plate is at least substantially excluded when a padlock engages through the aligned pair of holes. This offers a considerable gain in safety compared to alternative implementations in which the cylinder axis of a hole extends in the direction of movement of the hole, for example tangentially to a circumference.

In particular, the locking plate and the actuating plate can comprise stop means that correspond to one another, which define the actuating angle and the anchoring position and the loose position and are arranged on mutually facing main surfaces of the locking plate and the actuating plate. The stop means each provide two contact surfaces and prevent mechanical blocking a relative movement of the actuation plate and the locking plate beyond the actuation angle. Both in the anchoring position and in the loose position, two contact surfaces of the stop means are in contact with one another. Practically, the shut-off device comprises a handle which is fixed to the actuating plate and / or protrudes from the actuating plate and / or has an at least substantially U-shaped shape. The handle makes it easier to carry the shut-off device, as a result of which the shut-off device is easy to handle.

In some embodiments, the locking plate has two recesses and the actuating plate has a locking bolt that extends through the actuating plate, is held on the actuating plate so as to be displaceable perpendicular to the actuating plate and is pretensioned in the direction of the locking plate, which in the loose position has a first recess and in the anchoring position with the second recess is engaged. When the locking bolt is engaged, the actuating plate cannot leave the loose position or the anchoring position unintentionally, i.e. by inadvertent actuation, which increases the safety of the locking device.

In a preferred embodiment, the actuating rod is designed as an actuating shaft and the anchoring mechanism comprises a rotatably mounted anchoring shaft extending at an obtuse angle or perpendicular to the actuating shaft and a coupling device which is designed to transmit a torque between the actuating shaft and the anchoring shaft. In this way a pivoting movement is made possible for the locking element, the pivoting plane of which does not extend parallel to a surface of the ground, i.e. intersects the surface of the ground.

In such embodiments, the coupling device can be designed as an angular gear or comprise a universal joint. Angular gears comprise at least two bevel gears, i.e. conical gears. In order to achieve a transmission angle of 90 °, the coupling device can comprise two universal joints and be designed as a universal joint. As an alternative to this, the coupling device can also be designed as a flexible shaft which is bent to achieve the desired transmission angle, for example 90 °.

The shut-off device advantageously comprises a base plate, which is arranged opposite the locking plate and is fastened, in particular releasably or non-releasably, to the second free end of the hollow body. The base plate creates a distance between the hollow body and the ground when the shut-off device is arranged on the ground. In the space gained as a result of the created distance, the Be arranged anchoring mechanism. In addition, the base plate protects the second free end of the hollow body from wear as a result of displacement on the ground.

In one embodiment, the base plate is releasably fixed to the hollow body, in particular by means of a plurality of screws, preferably by means of four screws. Thanks to the releasable fixation, the base plate can easily be replaced in the event of a defect, for example a break, or wear. The four screws can be evenly distributed in a circumferential direction of the hollow body, for example at four corners of a bottom section of the hollow body molded onto the second free end, in order to ensure a secure attachment of the bottom plate to the hollow body.

The base plate advantageously comprises a plastic or a metal or consists of a plastic or a metal and / or a thickness of the base plate measured perpendicular to the main surfaces of the base plate lies in a range from 15 mm to 35 mm and is preferably 20 mm. The plastic can be selected from polyamide, PVC and the like. The metal can be designed as a sheet metal. The thickness of the base plate can be selected according to a space requirement of the anchoring mechanism. The base plate protects the hollow body from wear and tear as a result of displacement on the ground.

In advantageous embodiments, the anchoring shaft is rotatably mounted on the base plate. The anchoring shaft can reach through a hole provided in the base plate. Bearing elements, i.e. sliding bearings, can be fixed in the bore for the anchoring shaft.

The locking element is preferably designed in the shape of a hook and fixed on the anchoring shaft. The hook shape enables the locking element to reach under a transverse strut of a floor insert, which extends transversely to a pivot plane of the locking element. Thanks to the fixation, i.e. in particular a non-rotatable connection, the locking element is pivoted by turning the anchoring shaft. A hook-shaped locking element can be manufactured inexpensively and is easy to handle.

Ideally, the locking element is arranged on an outside of the hollow body. Thanks to the arrangement on the outside, the locking element is visible from the outside. It can be visually detected immediately whether the locking element engages behind the cross strut or not, and thus whether the The shut-off device is anchored to the ground or not. It is further noted that the locking element protrudes from an outer surface of the bottom plate in the longitudinal direction when the operating element is in the anchoring position. As a result of the external arrangement of the locking element, the shut-off device is inclined, ie its longitudinal direction is inclined relative to the longitudinal direction of a properly anchored shut-off device when the shut-off device is arranged on the ground without being anchored. In this way, incorrect operation of the shut-off device can be easily recognized visually, which is associated with increased safety of the shut-off device.

In some embodiments, the shut-off device comprises a first holding plate, which is fixed to the base plate, in particular releasably connected to the base plate, preferably screwed to the base plate, for holding the locking tube. The first holding plate positions the locking tube and can ensure that the locking plate is fixed relative to the hollow body by means of the locking tube and the base plate.

In addition, the shut-off device can comprise a second holding plate, which is fixed to the base plate, in particular releasably connected to the base plate, preferably screwed to the base plate, for holding the locking tube with a passage for mounting the actuating rod. The second retaining plate positions the locking tube and can ensure that the locking plate is fixed relative to the hollow body by means of the locking tube and the base plate. In addition, the second retaining plate serves as a bearing for the actuating rod.

The locking plate preferably has a central passage and the actuating rod is mounted in the central passage of the locking plate and in the passage of the second holding plate. Thanks to the central passage of the locking plate and the passage of the second holding plate, the actuating rod is mounted at two spaced-apart points, which is associated with a precise arrangement and alignment of the actuating rod. In the central passage of the locking plate and / or in the passage of the second holding plate, a bearing element, i.e. a slide bearing, can be fixed in each case.

Advantageously, passages of the second holding plate are in engagement with projections of the first holding plate and are welded to the first holding plate. The form fit between the projections and the passages defines a relative arrangement of the first holding plate and the second holding plate, whereby the assembly of the two holding plates is simplified. In addition, the projections engaging in the passages define suitable welding points.

The locking tube is advantageously welded to the first holding plate and / or to the second holding plate. The weld indirectly fixes the locking plate relative to the hollow body.

In some embodiments, the base plate has a passage provided for the locking element, which is in particular designed as an elongated hole, and a T-shaped passage. The T-shaped passage reduces the mass of the base plate and thus a weight of the shut-off device, which makes it easier to carry the shut-off device. Alternatively, the T-shaped passage or generally one of the

Passage serving to reduce mass can also be omitted in order to prevent or at least make more difficult the penetration of dirt into the hollow body and in particular penetration of dirt to the anchoring mechanism.

The invention also relates to a barrier system for a subsurface, which has a barrier device according to the invention and a floor insert that can be fixed in the subsurface and defines an engagement space for the locking element of the barrier device, with a cross strut arranged in the engagement space, which engages behind the locking element in an anchored state of the barrier device. The floor insert corresponds to the shut-off device and is the underground counterpart of the shut-off device. The floor insert enables the shut-off device to be anchored to the ground. The locking element can be pivoted into the engagement space. The cross strut of the floor insert is the underground counterpart to the locking element of the locking device.

The base insert preferably comprises a cover plate which has a slot-shaped engagement opening for the locking element. In the intended state of the floor insert, the cover plate ends flush with a surface of the subsurface and thereby continues the surface of the subsoil. Only the slot-shaped engagement opening interrupts the otherwise closed surface of the subsurface, which reduces the risk of tripping caused by the floor insert. Furthermore, the bottom insert can comprise two side plates which laterally delimit the engagement space and hold the cross strut, which side plates are arranged at a distance from one another and extend parallel to one another starting from the cover plate. A distance between the two side plates is chosen such that the locking element can be freely pivoted between the two side plates.

The base insert can also comprise a base element which delimits the engagement space transversely to the side plates and which is arranged between the side plates opposite the engagement opening. The base element closes the engagement space opposite the engagement opening, so that the base element as a whole provides a pocket-shaped engagement space.

Preferably, projections of the bottom element engage with passages in the side panels and are welded to the side panels. The protrusions and passages define a relative arrangement of the side panels and the bottom member, thereby facilitating mounting of the bottom insert. In addition, the projections engaging in the passages define suitable welding points.

An essential advantage of the blocking device according to the invention is that it is easy to handle and allows a reliable temporary or permanent blocking of an area of a subsurface. As a result, it can be an essential means of occupational safety and contribute to the safety of people who, for example, move together with autonomously driving industrial trucks on a surface such as the floor of a warehouse.

FIG. 5 shows a schematic illustration of a perspective side view of the floor insert of the shut-off system shown in FIG. 1.

Fig. 1 shows a schematic representation of a partially sectioned perspective side view of a shut-off system according to an embodiment of the invention. The shut-off system comprises a shut-off device 1. The shut-off device 1 is suitable and provided for being arranged on a substrate 10 and comprises an at least essentially tubular hollow body 2 which defines a longitudinal direction 20 of the shut-off device 1. The shut-off device 1 is designed as a guide cone, and the hollow body 2 has a circumferential wall 23 in the form of a cone jacket. Alternatively, the blocking device can also be designed as a blocking post, and the hollow body can accordingly have a cylindrical peripheral wall. Furthermore, alternatively, a cross-sectional contour of the hollow body perpendicular to the longitudinal direction 20 can also have a shape deviating from the circular shape, for example an oval, ellipsoidal or polygonal shape, in particular a triangular shape. A length 24 of the hollow body 2 measured in the longitudinal direction 20 is 500 mm, but in other embodiments can also be 300 mm, 700 mm or 900 mm or in a range from 100 mm to 1100 mm.

The shut-off device 1 further comprises an actuating element 3 which is arranged at a first free end 21 of the hollow body 2 and can be moved relative to the hollow body 2 between a loose position and an anchoring position. Fig. 2 shows a schematic representation of a perspective detailed view of the

Actuating element 3 of the shut-off device 1 of the shut-off system shown in FIG. 1 in the anchored position.

FIG. 3 shows a schematic representation of a perspective detailed view of the actuating element 3 of the shut-off device 1 of the shut-off system shown in FIG. 1 in the loose position.

The shut-off device 1 comprises an actuating plate as the actuating element 3, i.e. the actuating element 3 is designed as an actuating plate. The actuating plate 3 has an at least substantially circular outer contour and extends perpendicular to the longitudinal direction 20. The shut-off device 1 also includes a handle 34, which has an at least substantially U-shaped shape, is fixed to the actuating plate 3 and from which Actuator plate 3 protrudes. Of course, the handle can also be designed differently, for example have an L-shaped shape.

The actuating plate 3 has four holes 31. An actuating plate with exactly one hole 31 or one of four different plurality of holes 31 is also possible.

Furthermore, the shut-off device 1 comprises a locking plate 5, which is fixed relative to the tubular hollow body 2. The locking plate 5 extends perpendicular to the longitudinal direction 20. The actuating plate 3 extends in the loose position, the anchored position and in every position between the loose position and the anchored position parallel to the locking plate 5.

The locking plate 5 also has four holes 51 which, together with the holes 31 of the actuating plate 3, form four pairs of holes. Again, a locking plate with exactly one hole 51 or one of four different plurality of holes 51 is also possible. In any case, each hole 51 of the locking plate 5 forms a pair of holes with one hole 31 of the actuating plate 3.

Each hole 31 of the operating plate 3 and each hole 51 of the locking plate 5 are each formed as a bore and each have a cylindrical shape with a cylinder axis extending parallel to the longitudinal direction. The locking plate 5 also has two recesses 53, 54, which are also designed as holes. In other embodiments, they can be designed as depressions. In addition, the locking plate 5 has a central passage 55.

The actuating plate 3 comprises a locking bolt 35 which extends through the actuating plate 3, is held displaceably on the actuating plate 3 perpendicular to the actuating plate 3 and is prestressed in the direction of the locking plate 5. The locking bolt 35 is in the loose position with a first recess 53 and in the anchoring position with the second Recess 54 is engaged. When the locking bolt 35 engages, the actuating element 3 cannot move relative to the locking plate 5. In other embodiments, a movement of the actuating element 3 relative to the locking plate 5 can alternatively or additionally be prevented by means of mutually corresponding braking elements, i.e. by means of a frictional connection between the actuating element 3 and the locking plate 5.

The actuating plate 3 can be rotated relative to the locking plate 5 by an actuating angle 33 which is 150 ° and, in the case of embodiments according to the invention, lies in a range of 120 ° and 180 °. The locking plate 5 and the actuating plate 3 comprise stop means 32, 52 that correspond to one another, which define the actuating angle 33 and the anchoring position and the loose position and are arranged on mutually facing main surfaces of the locking plate 5 and the actuating plate 3.

The holes 31, 51 are arranged relative to one another in such a way that the four pairs of holes formed by the holes 31, 51 are exclusively aligned in the anchoring position, as can be seen from FIG. 2. In the loose position, however, the four pairs of holes formed by the holes 31, 51 are not aligned, as can be seen from FIG. 3. The four pairs of holes are arranged spaced apart from one another in a radial direction related to an axis of rotation of a rotational movement of the actuating plate 3. In the anchoring position, the actuating plate 3 can be locked, for example, by means of a padlock which engages through an aligned pair of holes.

The shut-off device also includes a mechanical anchoring mechanism 4, which is arranged opposite the actuating element 3 in relation to the longitudinal direction 20 and comprises a movable locking element 40. The locking element 40 is designed in the shape of a hook and is fixed on the anchoring shaft 41, in particular in a rotationally fixed manner the anchoring shaft 41 held. The locking element 40 is arranged on an outside of the hollow body 2.

The anchoring mechanism 4 also comprises a rotatably mounted anchoring shaft 41 and a coupling device 42. The coupling device 42 comprises a universal joint with two universal joints. In other embodiments, the coupling device 42 can be designed as an angular gear with bevel gears. The anchoring mechanism 4 also includes two bearing elements 43 for supporting the anchoring shaft 41.

The shut-off device 1 also comprises an actuating rod 30 which is fixed to the actuating element 3, extends in the longitudinal direction 20 and is movably mounted, which is arranged in the hollow body 2 and mechanically coupled to the anchoring mechanism 4. The actuating rod 30 is designed as an actuating shaft. The anchoring shaft 41 extends perpendicular to the actuating shaft 30. The coupling device 42 is designed to transmit a torque between the actuating shaft 30 and the anchoring shaft 41.

The locking device 1 also includes a locking tube 50 extending in the longitudinal direction 20 and fixed to the locking plate 5. The locking tube 50 is arranged in the hollow body 2, fixed relative to the hollow body 2 and partially protrudes from the hollow body 2.

The shut-off device 1 also comprises a base plate 6.

FIG. 4 shows a schematic illustration of a perspective top view of the base plate 6 of the shut-off device 1 of the shut-off system shown in FIG. 1. The base plate 6 is arranged opposite the locking plate 5 and is fastened to the second free end 22 of the hollow body 2 and is releasably fixed by means of four screws. In other embodiments, it can be permanently fixed to the second free end 22 of the hollow body 2 by means of rivets or by means of an adhesive.

The base plate 6 consists of the plastic polyamide. In other embodiments, the base plate can consist of another plastic other than polyamide or of a metal or comprise polyamide or another plastic or metal other than polyamide. A thickness 61 of the base plate 6 measured perpendicular to the main surfaces of the base plate 6 or the longitudinal direction 20 is 20 mm and, in the case of embodiments according to the invention, can be in a range from 15 mm to 35 mm. The anchoring shaft 41 is rotatably supported on the base plate 6 by means of the bearing elements 43.

Furthermore, the shut-off device 1 comprises a first holding plate fixed on the base plate 6

62 for holding the locking tube 50. The first holding plate 62 is detachably connected to the base plate 6, more precisely screwed to the base plate 6.

Furthermore, the shut-off device 1 comprises a second holding plate 63 fixed to the base plate 6 for holding the locking tube 50. The second holding plate 62 is detachably connected to the base plate 6, more precisely screwed to the base plate 6.

The second holding plate 63 comprises a passage 64 for mounting the actuating rod 30. The actuating rod 30 is in the passage 55 of the locking plate 5 by means of a bearing element fixed in the passage 55 and in the passage 64 of the second holding plate

63 stored by means of a bearing element fixed in the passage 64. However, the two bearing elements do not have to be present as separate components.

Passages of the second holding plate 63 are in engagement with projections of the first holding plate 62 and are welded to the first holding plate 62. The locking tube 50 is welded to the first holding plate 62 and to the second holding plate 63, but can also be welded only to the holding plate 62 or only to the holding plate 63.

The base plate 6 has a passage 65 provided for the locking element 40. The passage 65 is designed as an elongated hole. Furthermore, the base plate 6 can have a T-shaped passage 66 or a passage with a different shape.

Furthermore, the barrier system comprises a floor insert 7 which is fixed in the subsurface, for example by means of concrete.

FIG. 5 shows a schematic representation of a perspective side view of the floor insert 7 of the shut-off system shown in FIG. 1. The floor insert 7 can be fixed in the subsurface 10 and defines an engagement space 70 for the locking element 40 of the locking device 1. The floor insert 7 comprises a cross strut 73 arranged in the engagement space 70, which engages behind the locking element 40 when the locking device 1 is anchored. A cover plate 71, which has a slot-shaped engagement opening 72 for the locking element 40, belongs to the base insert 7. Furthermore, two side plates 74 laterally delimiting the engagement space 70 and holding the cross brace 73 belong to the bottom insert 7. The side plates 74 are arranged at a distance from one another and extend parallel to one another starting from the cover plate 71. The side plates 74 each have two passages 76 which, in the intended state, are penetrated by concrete, for example.

The base insert 7 furthermore comprises a base element 75 which delimits the engagement space 70 transversely to the side plates 74 and is arranged between the side plates 74 opposite the engagement opening 72. Projections of the bottom member 75 engage with passages of the side plates 74 and are welded to the side plates 74.

In order to anchor the shut-off device 1 to the substrate 10, the shut-off device 1 with the actuating element 3 is first provided in the loose position shown in FIG. 3. The provided locking device 1 is then carried on the handle 34 to a floor insert 7 fixed in the floor 10 and arranged on the floor 10 in such a way that the locking element 40 is arranged over the cross strut 73 of the floor insert 7. In a further step, the locking bolt 35 is released manually from the locking plate 5.

Then the actuating element 30 is manually applied with a torque. Due to the torque, the actuating element 30 is rotated through the actuating angle 33 into the anchoring position shown in FIG. 2. The torque acting on the actuating element 3 is transmitted to the anchoring shaft 41 via the actuating rod 30 and the coupling device 42. As a result, the anchoring shaft 41 is also rotated by the actuation angle 33 and pivots the locking element 40 in such a way that it engages behind the cross strut 73 of the floor insert 7.

When the actuating element 30 has reached the anchoring position, the locking bolt 35 engages with the locking plate 5 and the pairs of holes formed by the holes 31, 51 are aligned. By means of one or more padlocks, each of which penetrates an aligned pair of holes, the actuating element 30 can finally be securely locked in the anchoring position and consequently the locking device 1 anchored to the substrate 10 can be locked once or several times. To release the shut-off device 1, the above steps are carried out in the reverse order and in each case in the corresponding opposite direction. If the locking device 1 has been locked several times, all padlocks must of course be opened and removed from the pairs of holes penetrated before the actuating element 30 can be rotated manually into the loose position.
