Description

The invention relates to a barrier, which can be coupled as part of a transportable locking barrier with other barriers, according to the features in the preamble of claim 1.

From the US 6,296,234 B1 is a transportable Gedrängesperre known. This design of a Gedrängesperre is also referred to as a stage grid. Stage gratings are characterized by the fact that on the one hand they have to withstand high loads of crowding crowds, so that they have to be very sturdy, on the other hand they have to be light in weight because the stage grids are built up quickly before concerts and quickly after the concerts have to be reduced. The transport volume should also be low. Stage screens are therefore preferably folding structures that can be folded flat. For this purpose, the known stage gratings have a bottom-side frame part and a vertical frame part arranged approximately centrally on the bottom-side frame part. The two frame parts are hinged together via diagonal struts on the side facing away from the audience. In the foot of the vertical frame part, the coupling with the bottom side frame part takes place so that the Gedrängesperre is ready for use. For transport, the coupling is released and the vertical frame part folded down onto the horizontal frame part. A comparable design counts by the US 2010/0301259 A1 to the state of the art, as well as by the WO 2014/005581 A2 ,

The handling of the stage grid during construction and dismantling should be as simple as possible, but there is a risk of bruising by the folding mechanism, because the weight of the upper part is not insignificant. Adjacent stage grids are usually fixed to each other via bolts, which simultaneously fix the vertical frame part. This ensures that the stage gratings are connected on the one hand and also that they can not be folded and can not be moved. To stiffen the vertical part behind the stage grid, that is folded down on the stage side facing a folder level, which makes it possible to pull people out of the audience. The folded folder level also serves as a lock. However, it could happen in the case of missing screw connections in the foot area, that even when folded down folder level, the transportable Gedangsgesperren are folded. Bottom screwing is therefore essential for stability. Since the ground-level screwing is difficult partly due to non-aligned openings and in this case a hammer for driving the bolt was required, threads of the bolts were damaged in practice, so that the screws can not or can not be fully tightened. These screws then had to be replaced or partially replaced by thinner screws. Thinner screws facilitate the insertion of the screw connections, but do not guarantee the necessary safety.

On this basis, the invention is based on the object of making the construction and mounting of the locking barriers according to the invention simpler and safer.

This object is achieved by the features of claim 1 in a barrier that is part of a transportable crowd barrier and is designed to be coupled with other barriers.

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

The barriers according to the invention are designed so that they can be coupled to each other in the region of their vertical frame via a plug connection with the vertical frame of an adjacent barrier. This coupling is done by means of a clamp. The clamp is associated with mating receptacles located adjacent a face of the vertical frame. The plug-in receptacles are each near the end faces of the vertical frame, so that the clamping brackets have to bridge only a narrow gap. Each barrier therefore has at least one pair of plug-in receptacles. In the following explanation is explained several times how the clamp cooperates with the plug receptacles and engages. It goes without saying that the clamping clip does not cooperate with the plug-in receptacles of the same barrier, but in each case with plug receptacles of adjacent barriers in engagement, without this being mentioned below in any case.

The clamp is engageable with the socket receptacles to connect the barriers, with legs of the clamp engaging in or behind the plug receptacles and a web connecting the legs establishing the connection between the barriers. The bridge is at an angle to the thighs. The clamping clip is a substantially U-shaped bent or angled connecting element. The legs are preferably different lengths. The clamp is used to connect the barriers.

In a first embodiment, the active surfaces of the clamp are parallel to each other arranged. If, in addition, the active surfaces of the plug-in receptacles are arranged parallel to one another, adjacent barriers can be connected to one another very simply, ie with little effort, by inserting the clamping clip from above. If the leg is correspondingly short, so that little play when inserting, the insertion can be supported with a hammer. This makes it possible to build a bias, which pulls the faces of adjacent barriers against each other without play.

Alternatively, if at least one of the active surfaces is not parallel to a linear direction of movement of the clamping clip, the barriers can be pulled against each other by the clamping clip even after the wedge principle. As a result of this combination of linear movement direction and non-parallel active surfaces, the end faces of adjacent barriers can be displaced relative to one another via displacement of the tensioning clamp, wherein the connection of the tensioning clamp is preferably self-locking. As a result, the clamp can not solve independently.

The clamping clip designed according to the invention may itself have a non-parallel active surface, based on a linear direction of movement of the clamping clip or the other effective surface of the clamping clip. The clamp works on the wedge principle. The clamp, which itself can serve as a wedge, is displaced linearly. However, the part of the inclined plane of the wedge does not serve to move two barriers apart, but to approach each other. The clamp is therefore in a sense substantially U- or V-shaped configured and engages behind the two plug-in receptacles. The two legs are preferably directed downwards. The web can serve as a tool engagement surface for a striking tool. The assembly is preferably via a hammer. The clamp has no sensitive parts, such. Example, a thread, so that the mounting of the clamp is not a rotating, but via a purely linear movement, which is much faster than the attachment of suitable screwing tools in a bolt.

A clamp with mutually parallel active surfaces can also build a force transverse to the direction of movement of the clamp in cooperation with a non-parallel active surface of a plug-in receptacle and thus pull barriers frontally against each other. It is only one of the active surfaces at least partially not parallel to the other active surfaces to be able to build up a ramp force on the wedge principle, a clamping force in the clamp. Each of the active surfaces can be flat or curved. A wedge effect can be built up via concave or convex shaped active surfaces.

Wear can increase the depth at which a leg engages a socket. So that a clamping force on the wedge principle can be built even with incipient wear of the active surfaces, the web is in the locking position of the clip at a distance from the plug-in receptacles. The clear distance between the web and the plug-in receptacles in the locked state is at least 5 to 10 mm, preferably 10 mm to 20 mm, in particular about 20 mm.

The clamping bracket itself is preferably held captive in a first plug-in receptacle. This can be achieved via a cross bar, which prevents a linear withdrawal from the socket. However, the clamp is linearly displaceable in the first plug-in receptacle in order to be able to actuate it at all.

Thus, the clamp does not automatically slip out of the locking position is provided in a preferred embodiment that acts on the clamp a spring force. The spring force is to press the clamp in the direction of a locking position. The locking position is preferably located at a lower level than an open position, so that the gravity of the clamping clip holds in the locked position. Gravity supports the spring force. Gravity and spring force pull the clamp down into the locked position. This also facilitates the assembly, because for locking can be struck from above in this locking direction on the web of the clamp, which is much easier than to perform strokes from below.

The U- or V-shaped clamp has a leg with an active surface which is at an acute angle to an effective surface of the other leg. As a result, the above-mentioned wedge shape is created. Due to the wedge shape, it is possible when driving in the clamping clip to move the adjacent barriers towards one another by deeper driving of the leg into the plug-in receptacles and in this way to lock them together. This is possible only because an active surface of the leg is at an acute angle to an effective surface of the other leg. This does not necessarily mean that the active surfaces of the clamp must be the same angle to the effective surfaces of the clamp. However, a parallel arrangement of the active surfaces of the plug-in receptacles in relation to the active surfaces of the leg contacting them is preferred. This not only leads to a point contact, but preferably to a linear or flat contact. The surface contact causes a self-locking the active surfaces in contact with each other, so that the clamping bracket can be moved back only with the aid of a percussion tool in the unlocked position. The clamping forces in this context are so great that the spring forces, which hold the clamp in the locked position and the weight forces are negligible.

The acute angle is preferably less than 10 ° and is in particular 5 ° to 8 °.

The plug-in receptacles may preferably be designed as sleeves. Preferably, one of the plug receptacles is configured C-shaped in cross-section. The C-shape has the advantage that V-shaped extended clamps can be easily inserted into the socket. Through the opening of the C-shaped cross-section, a leg of the clamping bracket moves closer to the deepest of the cross-sectionally C-shaped plug-in receptacle during linear displacement in the locking position until the active surface finally rests against the deepest. With a cross-section tubular plug-in receptacle that would also be possible, however, the plug-in receptacle must be designed rather as a slot to simplify the installation. However, this leads to increased weight and unnecessary material costs. A cross-sectionally C-shaped plug-in receptacle fulfills the function just as well, is cheaper and also lighter.

The clamping clip is preferably held pivotably in the first plug-in receptacle, so that the clamping clip does not protrude beyond the front side of the barrier when not in use. This is an essential safety feature for the transport, because the barriers can be stowed in the folded state very space-saving. The risk of injury is also lower because you can not get stuck on the front side protruding clamp. The folding back of the clamp is under the influence of the spring force, which pulls the clamp down in the direction of the locking position. However, this spring force also causes friction of the clamp within its socket, so that it remains in the folded position when not in use.

Another security feature of the barrier according to the invention is that the vertical frame is connected in its upper region via supports hinged to the horizontal frame, wherein the supports are oblique to the horizontal frame and the vertical frame, so that the vertical frame can be stored for a transport position on the horizontal frame and wherein a lower end of the vertical frame has at least one hook which engages under vertical frame erected the horizontal frame and secures against vertical lifting. At least one horizontally acting blocking element, in particular in the form of a folder stage, is arranged between the vertical frame and the at least one support and prevents the at least one hook from pivoting back.

In the case of the barrier according to the invention, it is therefore no longer necessary to screw or bolt the lower end of the vertical frame to the horizontal frame. This eliminates ground-level installation work completely. The vertical frame is secured against lifting by a hook engages under the horizontal frame. It is advantageous that the horizontal frame is not weakened by the vertical frame. As a result, the horizontal frame in this area can be made of thinner-walled materials. The hook on the vertical frame also does not interfere with the horizontal frame, but engages it, so that the thin-walled hollow profile, preferably consists of the horizontal frame in this area, not damaged and thus his resistance moment against bending is not weakened by interruptions.

A significant importance in this context, the at least one locking element, in particular in the form of a horizontally acting folder level, the locking element holds the vertical frame in the vertical and ensures that the hook remains hooked under the horizontal frame.

Although it is considered sufficient if the blocking element rests in particular in the form of a horizontally acting folder level only on a projection on the vertical frame loose. In a preferred embodiment of the invention, however, a coupling part, for example in the form of a latching projection is arranged at the folder level, wherein the coupling part is adapted to engage in a matching coupling part, for example in the form of a locking receptacle on the vertical frame and a horizontally acting tension and pressure relief to form the vertical frame. The term coupling part is in this context for a father or mother piece. It is a positive coupling, comparable to a hook, the invention leaves open, which is the projecting and which is the female coupling part. Subsequently, it is assumed that a latching projection and a latching receptacle, which are each arranged on one of the components to be coupled. Such a locking projection preferably engages from above into a suitable receptacle, so that while the locking element or the folder level can be easily folded up during dismantling, however, forms an additional tension and pressure protection in the horizontal direction by the engagement from above in a console of a vertical frame. Through this measure, the safety of inventive barrier even further increased. But it is of course not synonymous with a notching of the hook expected when individual blocking elements or folder levels of a longer crowd locking should be slightly raised once. On the one hand, the blocking element can very easily be pressed down again. On the other hand, a single barrier is locked with neighboring barriers, so that the vertical frame of adjacent barriers also in each case by the locking elements or folder levels of the adjacent barriers in the hooked position on the horizontal frame remain.

If a neighboring barrier does not have the clamping receptacle necessary for connecting, a bore can additionally (as before) be arranged at the foot end of the vertical frame and suitably in the horizontal frame, so that adjacent barriers can be coupled to one another via a screw bolt used here. In addition, aligned bores or openings may be arranged in the upper region of the vertical frame, can be inserted through the bolts to connect barriers frontally with each other. The bores or openings are for this purpose perpendicular to the end faces in contrast to the plug-in receptacles whose longitudinal direction are substantially parallel to the end faces.

In a further embodiment of the invention, the vertical frame at its upper end at its opposite end faces on a father piece and a nut piece for the mutual positive engagement with adjacent barriers of the locking barrier according to the invention. This additional positive connection lends extra grip to the crowd barrier. Other father and mother pieces can be arranged on the horizontal frame in each case in the corner region of opposite end faces, so that there are several connection points for the positive engagement. Through these connection points, the barriers are positionally oriented relative to one another, which also enables and guarantees secure connection in the region of the clamping clips. The male and female pieces prevent a relative movement of the barriers to each other and in turn causes the clamping brackets by the preferred self-locking or jamming connection in the intended position remain even when people jerk at the barrier.

A connection of adjacent barriers with little play is made possible by the fact that the male pieces are each arranged off-center to the nut pieces to reduce horizontal displacements of adjacent engaging barriers. In two Vaterstücken and two Muttrstücken the father pieces can be arranged once in the horizontal direction left and horizontally right off-center of the nut pieces. The father pieces must therefore not be arranged centrally to the nut pieces, but in particular are arranged eccentrically. As a result, the game can be minimized and the connection accuracy can be improved.

The barriers according to the invention can be coupled to one another and also decoupled exclusively using a striking tool, in particular a hammer. There are no screwing tools required. In particular, there are no multiple screwing, on the one hand for holding the screw head and on the other hand required for holding the nut. The barriers according to the invention are not weakened by screw holes in the region of the frame and can therefore be made of comparatively thin-walled profiles.

The necessary for connection clamp is preferably made of steel or aluminum. The remaining components of the barrier are preferably made of aluminum profiles or aluminum sheets to save weight. The structural design of the barrier, in particular in combination with the hook, which engages under the horizontal frame, and with the locking element, in particular in the form of a folder level, which has a locking projection for securing against horizontally acting tensile and compressive forces, allows a lightweight barrier, the heavier In terms of handling is in no way inferior to designs, but on the contrary just as robust, can accommodate the prescribed minimum loads, but at the same time is easier and less expensive.

The lower material usage also allows a more cost-effective production. A significant advantage of the barrier according to the invention is that you no longer need to work close to the ground with screws and screwdrivers when building a Gedrängesperre, but simply connect with a hammer adjacent barriers and can quickly build up and dismantle to a Gedrängesperre.

The invention will be explained in more detail below with reference to exemplary embodiments illustrated in schematic drawings.

1 shows a barrier 1 , This barrier 1 is in 2 shown in another side view. Several such barriers can be put together to form a long impeding barrier. These are the barriers 1 in the area of their front sides to connect. Such Gedangsgesperren consisting of several barriers 1 are used as barriers in front of stages.

2 shows the barrier 1 from the direction of the stage. The barrier 1 consists of metal (aluminum or steel). In practice, the barriers are 1 aligned and connected. The barriers 1 each have a horizontal frame 2 and a vertical frame 3 , The horizontal frame 2 lies on a surface. The vertical frame 5 is located approximately in the middle above the horizontal frame 2 and is at its foot, that is at a lower end with the horizontal frame 2 coupled. In addition, the vertical frame 3 over two mutually spaced supports 4 with one end of the horizontal frame 2 connected. The pillars 4 extend obliquely from the viewer in 2 facing, stage side frame side 5 of the horizontal frame 2 up to an upper frame side 6 of the vertical frame 3 , The pillars 4 are on the frame sides 5 . 6 each hinged. In addition, the vertical frame 3 via a blocking element 7 in the form of a folder level with the columns 4 connected. The blocking element 7 extends approximately midway horizontally between the columns 4 and two vertical struts 8th at which support points for the blocking element 7 are formed. The blocking element 7 is at the supports 4 mounted pivotally and can be moved by a pivot axis through the two supports 4 runs, be folded up. This will do the in 1 at the detail IV drawn lower end of the vertical frame 3 released and can from the horizontal frame 2 be solved to the vertical frame 3 towards rear frame side 5 that means to the supports 4 to pivot. This allows the upper frame end 6 of the vertical frame 3 swung down and the vertical frame 3 together with the supports 4 flat on the horizontal frame part 2 be filed. The barrier according to the invention 1 is then in the transport position. In a manner not shown may include means for locking the vertical frame 3 on the horizontal frame 2 be provided in the transport position, causing an undesirable unfolding of the vertical frame 3 prevented.

The barrier according to the invention 1 is designed so that this only by an impact tool, in particular by a hammer with adjacent barriers 1 can be coupled. Screwing tools are not required for connection. This allows a quick and easy installation.

They are adjacent to the end faces 9 . 10 adjacent barriers 1 Plugs arranged over which the barriers 1 with each other in the area of their vertical frame 3 can be coupled. The connectors comprise in this embodiment each a clamp 11 and as a counterpart to the clamp 1 and 2 receptacles 12 . 13 , 1 and 2 show that appropriate connectors on each end face 9 . 10 are arranged in two different heights. Since the operating principle is identical, uniform reference numerals are used for both the upper clamp and the lower clamp, including the connectors, which are further discussed below.

The clamp 11 is in 3 shown in an enlarged view and as an item again in 8th , The clamp 11 is essentially V-shaped and has two legs 14 . 15 , In this embodiment, the legs are 14 . 15 different lengths. The longer the both thighs 15 Vertical direction extends parallel to a frontal profile spar of the vertical frame 3 , The profile spar is a square profile in this embodiment. At the square profile is the first plug-in receptacle 12 welded, as based on the 6 and 7 can be seen. It is a hollow cylindrical sleeve, which is used to guide the longer of the two legs 15 serves. Inside this tubular plug-in receptacle 12 can the clamp 11 Move vertically up and down (direction of movement B). Due to the hook shape, the clamp 11 not down from the socket 12 fall out. Also, the longer leg can 15 the clamp 11 not up from the socket 12 be pulled, because below the plug-in receptacle 12 a feather 17 ( 3 ) on the one hand on the plug-in receptacle 12 and on the other hand on an abutment 18 supported. The abutment 18 is, for example, a disc by a pen 19 is secured. The pencil 19 can be in a cross hole 20 ( 10 ) can be arranged. By the spring 17 becomes the clamp 11 always pulled down or pressed.

The two thighs 14 . 15 the clamp 11 are not parallel to each other, but are at an acute angle W to each other ( 10 ). The two thighs 14 . 15 are through a jetty 21 connected with each other. The jetty 21 is flattened on the upper side, so that a tool engagement surface is designed for a percussion tool. The figures show very clearly that in the area of the bridge 21 a hammer can be used to clamp the clamp 11 to drift down. This allows the second leg 14 with the second plug-in receptacle 13 at the other barrier 1 get connected. The second plug-in receptacle 13 is also on a vertical profile rail 16 of the vertical frame 3 attached, but adjacent to the opposite end face 10 , In this embodiment, the two plug-in receptacles 12 . 13 at the same vertical height and also have the same length measured in the vertical direction. The plug-in receptacle 13 However, unlike the sleeve-shaped plug-in receptacle 12 not vertically arranged with respect to their active surfaces, but the first plug-in receptacle 12 inclined towards. As a result, the two have plug-in receptacles 12 . 13 active surfaces 23 . 24 which are at an acute angle to each other, but at least not parallel to each other. 9 clearly shows that the active surfaces 25 . 26 the clamp 11 , to a certain extent on the mutually facing sides of the thighs 14 . 15 are arranged to stand in the same acute angle W to each other as the active surfaces 23 . 24 the plugins 12 . 13 , From the page presentation of 5 once again it becomes clear that the active surfaces 23 . 24 the plugins 12 . 13 at an acute angle to each other.

In 7 is the angle to recognize that the plug-in receptacle 13 from the bottom view with its lower end slightly further to the left is compared to the 6 (View from above). Based on 6 and 7 is also to recognize that the second plug-in receptacle 13 not circumferentially closed, but can be referred to in a horizontal cross-section as a U-shaped hook. The U-shaped design, that is, the open-sided designs makes it possible, the slanted leg 14 the clamp 11 easier in the plug-in receptacle 13 use to the neighboring barriers 1 by knocking down the clamp 11 to couple with each other.

To release the connection is only necessary, with a percussion tool from below against the first, longer leg 15 to beat that down from the first plug-in element 12 protrudes. Because the angle of inclination between the plug-in elements 12 . 13 is chosen so that here occurs a self-locking, always a certain adhesive force must be overcome before the clamp 11 can be solved from the connection position. The clamp 11 is raised so far that the shorter leg 14 from the second, in cross-section U-shaped plug-in receptacle 13 can be lifted out to the top. Then it will be around the longitudinal axis of the first plug-in receptacle 12 or the longer leg 15 pivoted. Preferably, it is pivoted through 180 °, so that the clamp 11 when not in use, no longer over the front 9 of the vertical frame 3 protrudes.

The clamps 11 are about one third of the height of the vertical frame 3 from the upper edge side 6 or from the horizontal frame 2 away. Other positive connection means are for coupling adjacent barriers 1 both in the lower frame area and at the upper frame area 6 intended. 2 shows that at the top frame area 6 of the vertical frame 3 in the area of the front side 9 a father piece 27 is arranged, which is adapted to a matching nut piece 28 on the opposite front side 10 of the vertical frame 3 to understand. As a result, a positive connection is also on the upper frame area 6 of the vertical frame. Other father pieces 29 from those in the perspective of 2 only one can be seen, are adjacent to the front and rear frame side 5 . 30 ( 1 ) of the horizontal frame 2 , At the opposite end 10 are located to the father piece 29 on the horizontal frame 2 two matching nut pieces. These are recesses in a profile spar 31 , There are therefore each adjacent to the frame sides (upper frame side 6 , front and rear frame side 5 . 30 ) a positive connection. These work across to the dividing plane of two barriers 1 that is, transverse to the faces 9 . 10 , The other form-fitting connections via the clamps 11 act perpendicular to the front sides 9 . 10 , The pairing of two groups of form-fitting connections enables a secure coupling of adjacent barriers 1 ,

It is considered to be particularly favorable if the father pieces 27 . 29 are each arranged eccentrically to the nut pieces or to the receptacles in the profile beams to the horizontal play of adjacent engaged barriers 1 to reduce. This refers in particular to the father pieces in the horizontal frame. Specifically, the father piece on the front frame side 30 as far as possible to this frame side 30 arranged out while the other father piece 29 at the rear, stage-side frame side 5 as far as possible to this frame side 5 is arranged. Then it does not matter if the profile spar 31 on the front frame side 30 or the second profile spar 32 at the rear frame side 5 and that the cross section of the nut pieces is larger than the father pieces 29 , Rather, it is enough if the father pieces 27 . 29 fill only a part of the cross section of the nut pieces around the adjacent barriers 1 to be able to pair with sufficient accuracy and with as little play as possible.

Another security feature of the invention, which allows a possible low-tool mounting, is a hook 33 as he in 4 is shown. The hook 33 is with a lower profile spar 34 of the vertical frame 3 welded. The horizontal frame 2 also includes a profile spar 35 that is from the front 9 to the front 10 of the horizontal frame 2 extends. He is not flush with a bottom 36 of the horizontal frame, but slightly up to the vertical frame 3 offset. The lower profile spar 34 runs parallel and immediately above the profile spar 35 of the horizontal frame 2 , where the hook 33 , which can be pivoted in the direction of the arrow P to the profile spar 35 to undercut, not down over a bottom 36 of the horizontal frame 2 protrudes. Through the hook 33 which is configured as an angle iron in this embodiment, the vertical frame 3 not raised in the position shown. It is sufficient if two narrower hooks 33 with the lower profile spar 34 of the horizontal frame 2 be welded ( 2 ). Above all, the lower profile spar 35 by the positive engagement with the hook 33 not weakened. The profile spar 35 will only be attacked. The hook 33 does not reach into the profile spar 35 ,

So the hook 35 does not independently swing back, but remains in the position shown when the barriers 1 locked together, the lower profile spar must 34 also remain in this position. This is due to the horizontally acting blocking element 7 ensured by which of the vertical frame 3 in horizontal direction opposite the columns 4 is supported. The blocking element 7 also has a coupling part 38 in the form of a locking projection, as in 14 or in 15 is shown. These are only cross-sectional representations through an end-side profile 37 of the blocking element 7 , The coupling part 38 is in the embodiment of 15 one at the bottom of the profile 37 of the blocking element 7 arranged square bar. In the embodiment of the 14 it is a pin, which extends into the interior of the profile 37 intervenes. The coupling part 38 is each with the profile 37 welded and engages in an associated coupling part 38 in the form of a locking receptacle ( 1 and 2 ), which are attached to the struts 8th of the vertical frame 3 is attached. The engagement of the locking projections in the locking receptacles prevents displacement of the struts 8th in the direction of arrow II in 1 that is from the columns 4 away and as well to the supports 4 out. The hook 33 is with his lower leg 40 longer than the profile spar 35 of the horizontal frame 2 is wide, so he even when people against the vertical frame 3 and want to damage this willfully, can not solve automatically from the hooked position. This would require the vertical frame 3 plastically deformed and thus the barrier 1 be destroyed. However, the arrangement according to the invention has the advantage that the vertical frame 3 with the horizontal frame 2 simply by connecting the coupling parts 38 . 39 , In particular impressions of a folder level can be secured in the snap-in recordings. Again, no further tools except a hammer are required.

Another significant advantage is that through the folding function of the barrier 1 this is immediately stabilized in the construction, as the hook under the floor panel or the profile spar 35 is inserted as soon as the blocking element 7 folded down. This is the barrier 1 immediately locked and ready for use. When the first coupling part 28 , For example, a locking projection also clamped in the second coupling part 39 , or the locking receptacle 39 engages, creates a frictional connection on the back of the vertical frame 3 , This allows the coupling parts 38 . 39 be charged to train and pressure, without the risk that the one coupling part 38 , For example in the form of a locking projection from a locking receptacle 39 solves. Such a single barrier 1 Can stand without risk of accidents and be moved safely, because there is a self-locking connection. If now neighboring barriers 1 through the father and mother pieces each other be brought, the Gedperrgesperre is already no longer completely displaceable. Only around the individual barriers 1 in the area of their faces 9 . 10 To secure on train, are now clamps 11 taken. The clamps 11 can also be referred to as impact brackets. The neighboring barriers 1 be with their faces 9 . 10 pulled together. Even vibrations that occur at a music event or even by the people who stand on such a barrier, can not cause the clamp 11 upwards triggers, because the spring force the clamp 11 always keeps in the locked position. In addition, there is at least one two clamps 11 out of reach of the person in front of the barrier 1 stand so that these are the barrier 1 under any circumstances can unlock. In addition, a corresponding impact tool would have to be carried to the self-locking clamping connection of the clamp 11 with the plug-in receptacles 12 . 13 to solve at all.

Alternatively to the embodiment of 1 to 10 is in the 11 to 13 another clamp shown. Due to the structural similarity, the reference numerals already used are used for this clamp. The clamp 11 of the 11 to 13 is different from the other clamp 11 only in that the shorter leg 14 parallel to the longer leg 15 runs. Therefore, the active surfaces are 25 . 26 parallel to each other. This design can also be used to connect barriers 1 be used, in particular, although the associated active surfaces 23 . 25 the plugins 12 . 13 parallel to each other.
