Description

The present invention relates to a clamping device for clamping at least one object between at least two posts, in particular a holding device for temporary barriers. Such a clamping or holding device is to be used in particular where sheet-like materials are to be clamped in order to fill a wall-like function and thus to provide a windscreen or a privacy screen. In this case, for example, a flat material can only be clamped between the posts when required and stored outside the time of use in the rolled-up state.

This is from the publication CH 682 759 A5 a roll wall for wind and / or visual protection known. Here, mobile, easy to install and disassemble rolling walls are described in which a fabric is pulled out of a vertically arranged receiving box and formed by the action of a spring shaft is automatically retractable. The fabric can be pulled out of the box as needed and hung with a designated drawbar holder. The insert is intended for outdoor living, trade fairs, retail markets and similar outdoor activities.

The publication DE 202 08 711 U1 describes a device for screening in outdoor areas, such as fences, balconies, gates, passage arches or other free viewing areas. Proposed is a vertically extending post, which is anchored at its end releasably or permanently in the ground. On this floor, a roll-up in the horizontal direction Rollo is attached or fastened. The roller blind in turn can be fastened to an abutment in the unrolled state. The removable anchoring of the post in the floor makes it quick and easy to install and dismantle it if necessary. After mounting the post, the blind can be fixed in it. The post itself is designed as a hollow housing, so that it serves to accommodate the rolled-up roller blind. By juxtaposing several posts, it is possible to provide larger areas with a visual, wind and / or sun protection. This solution also provides for the use of a spring-loaded roller blind in order to facilitate the rolling up and to allow the wind to give way even in the oncoming wind.

The disadvantage of this, however, is that it requires the releasable anchoring of the post in the ground in the described device to install this anchoring initially firmly in the ground. This results in a reduced flexibility of the device, especially when an application is provided at very different, initially not prepared for use places. Furthermore, a spring train is problematic because its traction is not constant.

The publication DE 299 09 855 U1 includes a screen against onlookers in road traffic accidents. The screen consists of at least two posts, which are releasably attached at a variable distance and adjustable at the bottom by means of a clamping device to a guardrail. Between each two posts, a tissue film or the like can be stretched. As a result, the privacy screen can be attached in a few steps to a central roof plank and constructed in any length. He can be removed just as quickly. The privacy screen consists of at least two tubes, which are attached to the guardrail by means of a clamping device. Inside the tube is a roller which is rotatably mounted about its axis. A slot in the tube allows the tissue to slide in and out of or out of the tube. A torsion spring located on the roller on which the fabric film is wound is tensioned when the film is pulled out. The film is provided with an edge reinforcement, which is hooked into hooks located on the pipe. When rolling up the fabric sheet onto the roll, the edge reinforcements of the holes form the abutment against the pipe. The tube has a lockable joint above the clamping device, whereby the tube can be pivoted in two directions. As a result, a vertical positioning of the tube is made possible, even if the crash barriers are deformed.

The shielding described is used exclusively where a guardrail extends and attachment is possible. Furthermore, the attachment takes place exclusively at the top of the guardrail, which leads to high loads on the material of the guardrail, especially in strong winds. If the guardrail is designed as a box profile, the described privacy can not be attached.

In summary, in view of the present state of the art, it is necessary in the case of the known tensioning devices that they be fixed in place for clamping at least one object or at least require a fixing fixed on the site. This is associated with relatively complex and heavy structures, including the flexibility of these devices suffers.

The object of the invention is therefore to provide a flexible, usable at different locations and easily installable clamping device for clamping and the active retightening of at least one object, which can be used, for example, as a tensioning device for a visual protection element in road traffic.

According to the invention the object is achieved by a tensioning device of the abovementioned type, wherein the tensioning device can be placed on a base or attachable to a fixed element Aufstellvorrichtungen with at least one post receptacle, wherein at least one of the post recordings a pawl device for locking the post in a locking position in the post recording having.

Since it is possible according to the invention to apply the clamping device with the aid of the erection devices both on a substrate as well as to fix it to a fixed element, results for the clamping device according to the invention a very high flexibility in the application. Thus, the clamping device according to the invention can on the one hand be set up variably on a wide variety of substrates at any location and on the other hand, due to their fastenability to the fixed element, to be permanently installed at a suitable location.

The attachment can be done for example on crash barriers, but also on perimeter posts, poles or trees. Further, it is possible by the inventively provided pawl device to lock at least the end of at least one of the posts in the post receptacle suitable, while can be brought during the locking of the post in a position in which the object provided between the post is tensioned. The pawl device prevents reverse rotation of the post and thus unwinding of the object. The pawl device may be located in the post receptacle or at the end of the post. It is also possible that individual elements of the pawl device are provided in the post receptacle and at the post end. Thus, the invention enables a fast, flexible and secure installation of the posts as well as a simple and variably adjustable clamping of the object between the posts.

It when the pawl device is a spring-loaded bolt locking device is particularly advantageous. Such a bolt locking device is easy to manufacture and allows easy operation. To release the lock is only the bolt to pull up and the locking of the post is released so that the post can be removed from its anchorage and / or a winding or unwinding of the object can be done on the post.

In a particularly advantageous embodiment of the invention, the bolt locking device has at least one locking bolt, which is performed by a provided in a retaining plate lower locking pin guide and by a retaining plate in a opposite locking bolt upper locking bolt, as well as arranged between the retaining plate and locking pin and concentrically around the locking pin Locking spring and a Arretierfederanschlag which is introduced into the locking bolt, wherein the retaining plate and the Arretierbolzenplatte spaced from each other and are arranged approximately parallel to each other at one end of the post, and wherein the locking pin from the retaining plate and arranged in the direction of one of the retaining plate, at least a locking recess having locking plate protrudes. The secure guidance of the locking bolt in the upper and lower locking bolt guide ensures easy movement of the locking bolt and avoids its jamming. This makes it easy to solve the lock by the locking pin against the Locking spring is pulled and the area of the locking pin, which protrudes from the retaining plate, is retracted into this. In this position, the locking pin can no longer engage in a locking recess. In the locking position, however, the locking spring, which presses against the Arretierfederanschlag, ensures that the locking pin engages in a locking recess of the locking plate. As a result, a particularly secure locking is possible.

In a preferred embodiment, the post receptacle has a guide pin, which is arranged to pass on or through the arresting plate, the post being hollow at least in a section opposite the guide post for receiving the guide post. The guide pin allows, together with the at least partially hollow inside post a very simple installation and safe guidance of the post, which also ensures a rotation of the post in the post recording. It is sufficient if a tubular post is used, which in any case has a cavity in the interior. If a post made of solid material is used, it can have a bore in the longitudinal direction for receiving the guide pin at the end. It is particularly favorable if the guide pin is arranged to pass through the arresting plate. In this case, the part of the guide pin, which does not serve to receive the post, can be used for accommodation in a mounting device which can be fastened to a fixed element. For a particularly secure and material-saving attachment of the post recording on the erection device is possible.

In a particularly advantageous embodiment of the present invention, at least one restraint bar is arranged on the arresting plate, under which the restraining plate can be inserted through a retaining recess provided on the circumference of the restraining plate. The retaining plate, in cooperation with the restraint bar, prevents the post from detaching itself from the post receptacle. For example, in strong winds could trigger forces occur that lead to slipping of the post of the guide pin or a different design post pickup. However, the retaining plate from the post transmits such forces on the restraint bar, which then prevents the post from slipping off the post receptacle. This feature is particularly important for safe use, especially on the road, where the tensioning device itself must not become a source of danger. The arrangement of the restraint bar on the locking plate and the retaining recess on the circumference of the retaining plate a simple assembly of the clamping device according to the invention is possible and at the same time ensures a secure mounting of the post on the post recording.

It has proved to be advantageous if at least one object support element is arranged between the object and the pawl device. The object placement element ensures that when winding the object on the post of the winding does not slip down, but is uniformly formed. Furthermore, in the event that the winding loosens during transport or storage, prevents parts of the object fall into the pawl device. The object support element can be designed as a rotationally symmetrical disk or in another way. For example, individual bolts protruding radially from the post are also suitable for serving as object support elements.

Particular advantages accrue when using the clamping device according to the invention, when the auflegbare on a base erection device is formed as a foot of at least one flexible mat assembly and at least one connected to the flexible mat assembly or integrated into this rigid or torsionally rigid construction, wherein the mat assembly is so large that it forms around the rigid or torsionally stiff construction a not connected to the rigid or torsionally rigid construction free edge strips. The auflegende on the ground erection device has a high sliding safety, since the flexible mat assembly generates a high friction between the ground and the erector. This is particularly the case when the flexible mat assembly is made of rubber. The warp resistant construction, such as a cast iron plate or a collapsible steel frame, may be applied to the flexible mat assembly, such as by bolting. Furthermore, it is possible to integrate the warp-resistant construction in the flexible mat assembly, for example by casting the torsionally rigid construction with the material of the flexible mat assembly. For rubber, this can be done for example by vulcanization.

Furthermore, this Aufstellvorrichtungsvariante has a very low center of gravity and a large footprint, whereby the entire jig is very Kippfest by the sum of their features. This set-up can be provided with a flat top available, which can be weighted if necessary, especially in very strong winds with ballast. For this purpose, a vehicle that drives the erection device with a wheel, can be used. In addition, the auflegbare on the ground erection device can be easily traveled or committed by their low height without the risk of accidents. In addition, this shape of the erector requires due to their asymmetrical plan during use a relatively small footprint and low height by a very low storage volume. This makes it particularly easy to stow in first-time vehicles or other vehicles with relatively little storage space, so that this embodiment is particularly suitable for use as a screen in traffic.

The storage of this form of clamping device according to the invention can be done in a stack or upright, for example on a cantilever. For this, the foot may have circular recesses, in each of which a guide pin engages another positioning device located next to it. The stored on the cantilever stack of erectors can be designed so that it can be lifted with a crane. Furthermore, such a cantilever can be attached to a vehicle, such as a trailer.

An automatic installation of such erectors on the ground can be done in such a way that the erectors are connected with drawstrings. A set-up device placed on the floor thus pulls the next one after it, when the vehicle on which the erection devices are mounted continues. This makes it particularly simple, inexpensive and with little effort a laying of a plurality of erection devices, for example, to form a long visual protection possible.

It has proved to be particularly favorable when the post receptacle is integrated or integrated centrally and / or eccentrically in the foot. Thus, the respective post can be received at different positions of the foot, which makes it particularly easy to respond to certain load directions and to position the post depending on demand. If, for example, an undisturbed passage or an undisturbed passage is to be ensured in a certain area, the post can be introduced into an edge area of the foot. In a particular embodiment of the invention, in which the foot allows a centric as well as an eccentric post arrangement, an additional device can be provided on the foot, which allows a change from the eccentric to the centric arrangement in a simple manner.

In an alternative embodiment of the invention, the set-up device is designed as an adapter device for attachment to a fixed element, wherein the adapter device has a stable, adapted to a contour of the fixed element or adjustable counter contour with at least one angle or a radius, the at least one flat or spans arched base on which the at least one post receptacle is provided, and wherein the adapter device has a connected to this basic construction belt system for attachment to a fixed element. The adapter device allows attachment of at least one post to the fixed element, for example to a guardrail, a boundary pole or a tree. For this purpose, the belt system, which is connected to the basic construction, placed around the fixed element and in turn attached to the basic construction and braced. For attachment to an example, round fixed element come as a contour of the adapter device, an angle or a corresponding radius into consideration. Thus, the adapter device rests securely on the fixed element while its open side is provided with the belt system. This is a particularly stable attachment at least one post of the tensioning device in the post receptacle on the adapter device possible. Such attachment holds without further security measures very high loads that can act on the object, stand. Particularly advantageous is the Gurtanbringung, as with this the entire fixed element can be enclosed and local loads can be avoided. This also reduces the risk of damage to the fixed element.

According to a further advantageous embodiment of the invention, at least one of the posts is extendable. An extension of the post can be made by attachment of an extension which is attached to the top of the post. The extension can also be done by an integrated post in the post, which remains there and if necessary pushed upwards out of the post telescopically. Due to the extension of the post is particularly flexible. Thus, for example, one is largely variable with regard to type, height and number of or exciting objects. Furthermore, attachments on the post, such as traffic signs, networks or lines that run in the longitudinal direction of the object to be clamped, can be applied. In addition, can be placed on the extension elements for bracing, for example, clamp two parallel rows of jigs against each other. In addition, it is possible to put on the extension roof-like constructions.

In a particularly preferred embodiment of the tensioning device according to the invention, the object is at least one privacy tarpaulin. Thus, with the present invention, a particularly flexible, cost-effective and quickly deployable privacy device can be provided. Such flexibility is required, for example, when the privacy screen is installed in a traffic accident to provide workers with better working conditions and to reduce the risk of congestion and accidents for passing vehicles.

In an alternative embodiment of the tensioning device according to the invention, the object is at least one barrier net or barrier grid. If a locking net is clamped with the tensioning device, a barrier suitable for many purposes can be erected in a particularly simple and fast manner. If at least one barrier grid is attached to the posts, this creates an easily installable and, moreover, very stable and rigid barrier. Such barriers can be used, for example, on roads as a game fence in times of particularly intense wilderness change. A use can also be made in such cases, in which, for example, a passage of people should be prevented, without significantly affecting the view.

A further option of the invention provides that the object is at least one individually tensionable rope or band. By a single or several tensioned ropes or bands Shutdown can be done as needed in a way that minimizes visibility without the need for a high network. There may be several coiled ropes or straps on the post, of which so many are pulled out of their receptacle and attached to the opposite post, as required for the particular application.

It may be advantageous in certain embodiments, if the at least one rope or band is electrically conductive. Thus, for example, a fence for animals or a pasture fence can be built. The ability to attach different objects to the post, such a shut-off device for different species can be used. For example, at the bottom of a low fence or a network may be provided, the mesh can also be interspersed with electrically conductive materials. Such a network can be used, for example, for sheep petting. If larger animals are provided in the pen, such as horses, one or more electrically conductive bands can be pulled out above the net or bands in the lower part of the post to prevent them from jumping over by a large animal.

Particularly advantageous is the use of the clamping device according to the invention in the construction of a pavilion, which is formed from at least two oppositely arranged clamping devices according to one of the preceding claims, wherein on the posts of the clamping devices, a roof is placed. The roof can be designed as a pent roof or in other ways, such as a tonneau roof. As a result, roofed aisles, for example between exhibition halls at a trade fair, can be constructed in a particularly simple and cost-effective manner. Furthermore, a flexible and location-independent construction of smaller exhibition spaces, which are built as pavilions, feasible.

Fig. 1 schematically shows a front view of an embodiment of a tensioning device 1 according to the invention with partially mounted Sichtschutzplane 2. The Sichtschutzplane 2 is mounted secured to a fixing rod 7 such that the Sichtschutzplane 2 can not rotate about the fixing rod 7. For example, the protective tarpaulin 2 can be fastened with screws to the fixing rod 7. In this case, the protective tarpaulin 2 can be guided around the fixing rod 7 in an annular manner and the respective screws can be countersunk in a shell provided on the protective tarpaulin 2.

The protective tarpaulin 2 is partially wound on a post 3 shown on the left in the figure. By an operator, one end of the screen 2 is detected on the fixing rod 7, which is arranged at the end of the screen 2, and unwound from a roll 47 of the screen 2. The pulling direction takes place in the direction of a second post 3 ', in which the fixing rod 7 is mounted. Serve object support elements 8, have the appropriate recordings, in which the fixing rod 7 can be hung quickly and safely.

The posts 3, 3 'are used in aufstellbare on a substrate 46 Aufstellvorrichtungen 4. The connection of posts 3, 3 'with the auflegbaren on the ground 46 erector 4 serve post receptacles 5. These protrude in the illustrated embodiment with a tubular guide pin from the respective post receptacle 5 upwards, so that the rotationally symmetrical running post 3, 3' in the guide pins, which in detail in the Fig. 5, 6 and 8th are shown can be used.

The post 3 has in the post receptacle 5 a in the Fig. 5, 6 and 8th shown in detail pawl device 6. Their blocking effect is adjustable and can be canceled, so that the screen 2 can be unwound as in the example shown by the winding 47 and between the posts 3, 3 'can be stretched.

If the fixation rod 7 is mounted on the post 3 ', the pawl device 6 is locked in place, and the protective tarpaulin 2 is tensioned by turning the reel 47 back. The turning back takes place in the released direction of rotation of the pawl device 6, while a rotation of the coil 47 in the opposite direction and thus a relaxation of the voltage of the sight protection tarpaulin 2 are prevented by the blocking action of the pawl device 6.

Fig. 2 schematically shows a perspective view of another embodiment of a tensioning device according to the invention 1 'with clamped screens 2 and auflegbaren on a base erectors 4. The erectors 4 each form a foot with a mat assembly 9, a rigid or torsionally rigid construction 10 and at least one, introduced therein post receptacle 5 on. The mat assembly 9 is flexible and consists in the illustrated embodiment of rubber. With the flexible mat assembly 9, the rigid or torsionally rigid construction 10 is connected. In other, not shown embodiments of the present invention, the torsionally rigid construction 10 may also be integrated in the flexible mat assembly 9. The base of the flexible mat assembly 9 is greater than that of the rigid or warp-resistant construction 10. This results in an edge strip 48, which projects beyond the rigid structure 10 at least on one side. As a result, on the one hand a large footprint and on the other hand provided by the always resting on the ground edge strip 48 of flexible material high tipping safety for the clamping device 1 '.

The rigid or torsionally rigid construction 10 of the erection device 4 has at least one eccentric post receptacle 5. In other, not shown embodiments According to the invention, the post receptacle 5 can also be provided on a position other than that shown here by way of example in the edge region of the torsionally rigid construction 10. In principle, the post receptacle 5 can also be provided centrally in the foot. As a result, the posts 3, 3 'at different positions, centrally and / or eccentrically, bring in the erectors 4, whereby the entire clamping device 1' very variable and can be adapted in particular to load directions or paths to be kept clear of obstacles. If, for example, the tensioning device 1 'is set up along a road or a path, a hindrance can be avoided on the side on which persons or vehicles pass by aligning the positioning devices 4 with the other, non-committed side.

The posts 3, 3 'each have at the end, which is connected to the erector 4, one in the Fig. 5, 6 or 8th Ratchet device 6 shown in more detail. These allow a tensioning of the screening tarpaulin 2, as soon as it is connected to the attached at the end of the tarpaulin fixing rod 7 with the next post 3, 3 '. The connection is made to object support elements 8, which are located at the upper and lower end of the posts 3, 3 'and have means for locking the fixing rod 7.

The 3 and 4 illustrate the procedure for inserting the fixing rod 7 in Fig. 2 illustrated embodiment in a provided on the post 3 Fixierungsstabaufnahme 20. As in Fig. 8 shown in detail, the Fixierungsstabauf-take 20 is provided as a bore in an annular running around the post 3 object support element 8. As shown in the figure below Fig. 3 it can be seen, the Fixierungsstabaufnahme 20 a retaining bolt recess 58 which projects approximately nose-shaped from the Fixierungsstabaufnahme 20. In addition, the fixation rod 7, which in Fig. 3 only fragmentary shown, a laterally located at its lower end retaining pin 57, the size of which is designed so that it is insertable into the retaining pin recess 58 of the Fixierungsstabaufnahme 20.

For this purpose, the fixing rod 7, on which the screen 2 is wound, as indicated by the arrow B in Fig. 3 shown guided by the Fixierungsstabaufnahme 20 so that the retaining pin 57 slides through the retaining pin recess 58.

If the fixing rod 7 is passed through the Fixierungsstabaufnahme 20, it is, as in Fig. 4 schematically shown, rotated so that the retaining pin 57 is no longer aligned with the retaining pin recess 58. As a result, the fixing rod 7 in the in Fig. 4 shown position, which in the lower part of Fig. 4 again shown in plan view, locked. As above with regard to Fig. 1 executed, in this case the screen 2 is attached to the fixing rod 7, that the screen 2 is not about the fixing rod 7 can turn. The protective tarpaulin 2 is fixed to the fixing rod 7, that when the screen 2 is stretched, the retaining pin 57 is always opposite the retaining pin recess 58 and thus the screen 2 can not solve.

Fig. 5 schematically shows a sectional front view of an embodiment of a pawl device 6 with a mounted on a guide pin 17 of a post receptacle 5 post 3. The guide pin 17 is fixed to a torsionally rigid construction 10 of an example in Fig. 2 shown erection device 4 connected. Further, a retention bracket 15 is attached to the rigid or torsionally rigid structure 10.

At one end of the post 3, this has a locking pin holding plate 13 and a retaining plate 12, which are provided annularly and parallel to each other at the post end. Through both plates through a locking pin 11 is guided over the concentrically arranged in the region between the retaining plate 12 and the locking bolt plate 13, a locking spring 14 is arranged. The locking pin 11 is guided in the two plates, the retaining plate 12 and the locking pin plate 13, so that it can slide along the post axis. The locking spring 14 holds the locking pin 11 in a position that lets it protrude through the retaining plate 12 therethrough.

The retaining plate 12 has a retaining recess 16. Is this as in Fig. 5 represented, the retaining bracket 15 opposite and the post 3 placed on the guide pin 17, the post 3 can be placed on the rigid or torsionally rigid construction 10 and rotatably guided on the guide pin 17. In the in Fig. 5 illustrated embodiment, the rigid or torsionally rigid construction 10, waiving a separate locking plate 19, as in the in Fig. 8 shown embodiment, locking recesses 21 on. The radius, in which the locking recesses 21 are arranged around the center of the guide pin 17, corresponds to the distance of the locking pin 11 from the center of the post 3.

Fig. 6 schematically shows a sectional front view of the pawl device 6 from Fig. 5 with post 3 secured by the retaining plate 12. The guide pin 17, which, as in Fig. 5 The retainer plate 12, which is connected to the post 3, is located below the restraining bar 15, between it and the erection device 4, and is supported by the restraining bar 15 against removal of the post 3 secured by the guide pin 17.

In addition to securing against removal of the post 3 this is in the representation of Fig. 6 secured against rotation by the pawl device 6. The end of the Locking pin 11, which projects through the retaining plate 12 in the direction of the rigid or torsionally rigid construction 10, is inserted into a locking recess 21. Thus, the locking pin 11, which is guided in the retaining plate 12 and the locking pin plate 13, holds the post 3 firmly and prevents its rotation. The engagement of the pawl device 6 is effected by the locking spring 14, which pushes the locking pin 11 into the locking recess 21.

To release the lock of the locking pin 11 is to pull at its angled end of the handle up and against the pressure of the locking spring 14. Thus, the locking pin 11 is removed from the locking recess 21 and the pawl device 6 is released. In order to remove the post 3 in total from the guide pin 17, the post 3 must be rotated together with the retaining plate 12 until the retaining recess 16, the in Fig. 5 can be seen, is arranged with the retaining bracket 15 in opposite position. Then there is no assurance of the post 3 against peeling more and the post 3 can be removed from the erector 4.

Fig. 7 schematically shows a view of a guided around an obstacle 18 around clamping device 1 'from above. For this purpose, several deployable on a substrate erectors 4 along a planned Aufstellweg of privacy screens 2 are arranged. The erection devices 4 have post receptacles 5, which are each introduced eccentrically in the erection device 4. In the post receptacles 5 posts 3 are introduced and clamped between them the screens 2. Since the post receptacles 5 are not provided in the foot center in the erection devices 4 and the erection devices 4 can be arranged according to the particular circumstances, the posts 3 can be variably positioned and the sight protection tarpaulin 2 can be guided very close to the obstacle 18 without causing a collision between the obstacle 18 and the respective foot comes.

Fig. 8 schematically shows a perspective view of an embodiment of a usable in the clamping device according to the invention pawl device 6. This consists in the illustrated embodiment of two parts, wherein a first part is connected to one end of a post 3 and a second part with a positioning device, not shown here the erector 36 from Fig. 9 , is connected or in the erector 4 from Fig. 1 , is integrated in the torsionally rigid construction 10.

The first part connected to the post 3 has at least one object support element 8, which prevents a slide-down of an object, for example a privacy tarpaulin 2. In the in Fig. 8 shown embodiment of the invention, the object support member 8 is designed in a ring around the post 3. In other, not shown embodiments of the present invention, one or more projections can be provided at this point be to form a Objektauflageelement 8. Such protrusions can be carried out, for example, from concentrically and at right angles from the post 3 protruding bolt.

Furthermore, the object support element 8 at least one already above with respect to 3 and 4 described Fixierungsstabaufnahme 20 which is formed in the form of provided on the circumference of the object support member 8 holes with projecting retaining bolt recesses 58. In the Fixierungsstabaufnahme 20, as explained above, for example, in the Fig. 1 and 2 shown fixing rod 7, which is provided at one end of a screen 2, introduced and fixed there.

The pawl device 6 furthermore has a locking bolt holding plate 13 provided on the post 3 parallel to the object supporting element 8, into which an upper locking bolt guide 45 for a locking bolt 11 is inserted. This is arranged parallel to the post 3 is a retaining plate 11. The retaining plate 11 has a retaining recess 16 which is arranged on the circumference of the retaining plate 11. Furthermore, the retaining plate 12 has a lower locking bolt guide 44, which ensures a secure guidance of the locking pin 11 together with the upper locking bolt guide 45, without this pinching in the guide.

Between the retaining plate 12 and the locking pin holding plate 13, a locking spring 14 is arranged, which is guided by the locking pin 11. In the locking pin 11, a locking spring stopper 22 is introduced, on which the locking spring 14 is seated and presses the locking pin 11 in the direction of the retaining plate 12. The Arretierfederan-beat 22 is executed in the illustrated embodiment as a transversely through the locking pin 11 guided pen. However, the execution of suspension and stop can also be realized in other ways. For example, a disc spring or rubber spring can be used for the suspension. The stop can also be realized by pressed on both sides of the locking pin 11 noses.

The second part of the pawl device 6 carries a guide pin 17 which is connected thereto. In the illustrated embodiment, the guide pin 17 is guided through the locking plate 19 therethrough. As a result, a receiving element 23 for an adapter device 36 is formed on the region of the arresting plate 19 opposite the guide pin 17. In other embodiments of the invention, the guide pin 17 can also end in the arresting plate 19, so that no separate receiving element 23 is present.

The locking plate 19 has on its surface a plurality of locking recesses 21, 21 '. These are pressed in the present embodiment in the locking plate 19 as depressions. In other embodiments of the present invention, the locking recesses 21 may be cut into the locking plate 19 with laser. In a particularly advantageous embodiment, these locking recesses 21 are designed so that the recess has a slope on one side and has a steep flank on the other side. The bevel extends in the circumferential direction of the locking plate 19. As a result, the pawl device 6 depending on the direction develop their blocking effect. If the locking pin 11 pressed into one of the locking recesses 21 is pulled in the direction of the sloping flank, if a torque acts on the post 3, the locking bolt 11 can slide out of the locking recess 21 and slip into a next locking recess 21 '. If, however, a torque is built up in the opposite direction on the post 3, the locking bolt 11 can not slide out of it via the steep flank of the locking recess 21. A rotation of the post 3 in this direction is thus prevented. Alternatively, the resting in the Arretieraussparungen 21 end of the locking pin 11 is chamfered and leave the Arretieraussparungen 21 on all sides with a steep flank. This results in a simplified production.

The locking plate 29 further has on its the post 3 facing surface on a retaining bracket 15 in the form of an approximately "z" -shaped angle. This acts in conjunction with the retaining plate 12 and introduced in the periphery retaining recess 16. When placing the post 3 on the guide pin 17, the retaining plate 12 slides directly to the locking plate 19 when the retaining bracket 15 and the retaining recess 16 directly opposite. If thereafter a rotation of the post 3 relative to the guide pin 17, the post 3 is secured against slipping from the guide pin 17, since the retaining clip 15 is above the retaining plate 12 and this holds on the locking plate 19. This is particularly advantageous when loaded by the tensioning device according to the invention sighting tarpaulin 2 is loaded by wind, which could solve the Sichtschutzplane 2 together with the post 3 of the guide pin 17 of the post recording. Instead of only one restraining bar 15, a plurality of restraining bars 15 can also be arranged on the arresting plate 29.

Fig. 9 shows in perspective a sectional side view of an adapter device 36 which is attached to a fixed member 40, here a guardrail. For this purpose, a basic construction 39 of the adapter device 36, which in the present case has a right angle, is applied to the fixed element 40. The basic construction 39 may also have other contours, such as a radius adapted to a radius of the fixed element 40, as a mating contour to the fixed element 40.

To fasten the basic structure 39 to the fixed element 40, a belt system 37 is provided. This is placed around the fixed member 40 and has at one end a belt attachment 41, with which it is connected to the basic structure 39. At the other end of the belt system 37, a belt tensioner 42 is arranged, with which the belt system 37 is tensioned around the fixed element 40. Thus, the adapter device 36 is fixed to the fixed member 40. For receiving a post 3, a post receptacle 38 is provided and connected to the basic construction 39. The post receptacle 38 must be constructed in this embodiment so that the in Fig. 8 shown guide pin 23 can not rotate. The adapter device 36 thus enables a secure and rigid attachment of the post 3 of the tensioning device according to the invention to the fixed element 40, wherein instead of the in Fig. 9 As a fixed element used guardrail and a boundary pole, a pole, a post or a tree for attaching the adapter device 36 may be used.

The clamping devices 1 form, on the one hand strung together, a privacy screen and, on the other hand, face each other with a space enclosed by two walls. For this purpose, two rows of erection devices 4 and inserted into this post 3 are provided. At the upper, the erectors 4 opposite ends of the posts 3, a strut 26 is disposed between each two opposing posts 3. This ensures in the upper part of the post 3 a uniform distance of the post 3 and increases the stability of the resulting bow.

About the struts 26 extends a barrel roof 25, which connects two opposite units of the clamping devices 1 with clamped screen 2. This creates a closed vault where both side walls and the roof are closed. As a result, closed aisles, for example, to connect exhibition halls together, are formed. However, covered areas of other shapes and sizes can also be produced. For example, partitions may be omitted by retracting the privacy screens 2 in the areas where a closed wall is not desired. Then arises in these areas a larger space when several fixtures 1 are placed in parallel.

Fig. 11 schematically shows a perspective view of an embodiment of a clamping device 1 according to the invention, wherein at least one post 3 of the clamping device 1 has an extension 27. In the embodiment shown, the extension 27 is mounted inside the post 3 designed as a tube and can be pulled out telescopically during use. If the extension 27 is pulled out in the desired length, it is locked. The locking takes place in the present embodiment with a secured pin which is pushed through a hole in the extension 27 and prevents slipping back into the post 3 inside. Other forms of locking, such as a bayonet lock or a Spreizdübelarretierung, can also be used.

An extension of the post 3 can also be realized in other ways. The extension 27 can be placed, for example, as an additional element on the end of the post 3 and secured thereto. This is particularly advantageous if the post 3 has no cavity in the interior.

Fig. 12 schematically shows a front view of an embodiment of a clamping device 1 according to the invention with a post 3 with loaded set-up device 4. The post 3 is connected by a post receptacle 5 with the erector 4 releasably form-fitting manner. To achieve a higher resistance to tipping the erector 4 is charged. The load can be done by any ballast elements 28. In the present example, a vehicle is used for this purpose, which has been driven onto the positioning device 4 with a wheel. This is possible because the erector 4, as above with respect to Fig. 2 described, can be trained very flat and therefore easy to drive. By placing a ballast element 28 on the erector 4, the stability of the clamping device 1 according to the invention can be further increased, so that even at higher wind speeds and thus high loads, which act on a planned example by the tensioning device 1 screen 2, ensures a secure footing ,

Furthermore, the positioning device 4 in the region of the rigid or torsionally rigid construction 10 on a stacking aid 35 already mentioned above. The stacking aid 35 is here designed as a curved oblong hole, through which the guide pin 17 of one of the adjacently arranged behind or positioning device 4 can be pushed through, which forms an anti-rotation in cooperation with a center pin in the center of the erectors 4.

FIGS. 18 and 19 schematically show a machine installation possibility of erection devices 4 of a tensioning device according to the invention in a plan view and a side view. For this purpose, several erection devices 4, such as in Fig. 13 shown stacked on a vehicle 30. The erection devices 4 are connected by tension elements 34, in the illustrated embodiment by two tension elements 34. The length of the tension elements 34 between the erection devices 4 corresponds to the distance that the erection devices 4 should have at the place of use. The depositing is now carried out so that a first set-up device 4 is placed on the substrate 46. If the vehicle is moved in the direction indicated by the arrow A, the tension elements 34 tighten and draw a second set-up device 4 from the vehicle 30 down to the ground 46. If the second set-up device 4 lies on the ground 46 and the vehicle 30 has the distance to the next provided storage space a set-up device 4, tighten the tension members 34 again to deduct a third erector 4 from the vehicle 30. In this way, the mechanical storage of the erection devices 4 takes place, in which the erection devices 4 can be laid very quickly and with little manpower.

Fig. 20 schematically shows a front view of an embodiment of the clamping device according to the invention with inserted barrier grid 49. The barrier grid 49 consists in the present embodiment of two horizontally extending profiles, the upper transverse profile 53 and the lower cross-section 54, between which vertical, evenly spaced vertical profiles 56 extend. As profiles, pipes, but also components with differently shaped cross-sections can be used. Their arrangement can be done in any way to obtain a rigid barrier grid 49. The barrier grid 49 is held between two posts 3, respectively. The posts 3 are anchored on a stand-up device 4. It is particularly advantageous that the clamping device with the barrier grid 49 increased stability against tipping receives when people step on the flat 4.

Fig. 21 schematically shows a perspective view of the clamping device according to Fig. 20 with suspended barrier grid 49. The locking grid 49 are mounted with a fixed to the ends of the upper transverse profile 43 of the barrier grille 49 retaining ring 51 in the post 3. The lower cross-section 54 has a retaining clip 52 at its ends. This also engages the post 3, prevents pivoting of the barrier grille 49 against its longitudinal direction, but at the same time secures a free pivoting in the longitudinal direction of the barrier grating 49. This results in the ability to compensate for differences in height of the ground when laying the barrier, since the barrier grid 49 after can tilt up and down, which on the one hand allows a game in the retaining ring 51 and on the other hand, the open, elongated headband 52 does not hinder.

The protection against lifting of the barrier grille 49 is effected by a lock 55 which is arranged on the post 3. The lock 55 is designed so that the retaining ring 51 can not be pushed over this, when it is brought into the locked position.

Fig. 22 illustrates the function of in Fig. 21 shown clamping device, wherein the locking grid 49 is held in the post 3, which is inserted in the erector 4. The rising terrain of the ground provides for an inclination of the barrier grille 49, which is made possible by the game in the retaining ring 51 and the open retaining pads 52.

Fig. 23 schematically shows a side view of an embodiment of a clamping device according to the invention with barrier grid 49 and strut 50. The strut 50 is fixed to the post 3 and to the erector 4 and forms a rigid connection between the two elements. As a result, a load on the post holder 5 and the base of the post 3 is prevented from bending and this only charged to train or pressure. This results in a particularly high strength of the clamping device, which thus withstand particularly high loads that can occur in a barrier, for example, by crowds.
