Definitions
- the present invention relates to a barrier with at least one structural unit and a device for erecting the barrier.
- Barriers and walls are built in earthworks, roads, hydraulic engineering, etc. with the help of sandbags, for example.
- cube-shaped wire baskets are also suitable, which are filled with rock and which can be stacked on top of and next to each other.
- Walls or barriers can be built from the sandbags and the wire baskets.
- the width of such building blocks is comparable with their height, so that such building blocks can be moved relatively laterally if a sufficiently large force acts on the wall built up from such building blocks from the front.
- Such a situation exists, for example, in the event of floods, in which the water masses act with great pressure on the large area of the barrier. Or in road construction it can happen that the earth masses act on a wall made of wire baskets.
- the object of the present invention is, inter alia, to eliminate the mentioned and other disadvantages of the prior art. According to the invention, this object is achieved with the barrier of the type mentioned at the outset as defined in the characterizing part of patent claim 1.

- FIG. 16 is a top view of the main part of the brake device from FIG. 15.
- the present barrier comprises at least one elongate structural unit 100.
- This structural unit is shown in a front view in FIG. 1.
- This assembly 100 has an elongated base body 101, which is a container and which is advantageously made of a resilient material.
- This resilient material can be a textile structure, for example, and in this case it can be a woven or non-woven fabric.
- This resilient material can also be a film made of plastic or rubber.
- a rotatable material can be selected as the material of the cover 101.
- the material of the base body 101 can also have at least two layers of different materials. For example, it can be a textile structure coated with rubber or a plastic.
- This elongated base body 101 has the shape of a tube which has end parts 102 and 103. These end parts 102 and 103 can be closed.
- the resilient material is the respective end portion 102 or 103 gathered, so that this gathered portion of the length of the tube 101 constitutes a nozzle 104.
- a closing means 105 In that area of the neck of the connecting piece 104, which adjoins the remaining part of the hose 101, there is a closing means 105, which wraps around the neck in this area of the hose 101 and keeps it closed.
- This closing means 105 can be a piece of cord, a strap or just a piece of wire, the ends of which are firmly connected to one another in such a way that they can keep the relevant end part 102 or 103 of the hose 101 closed.
- a filler material 106 (FIG. 3) is located inside said casing 101.
- the amount of filling material 106 is selected so that this material 106 fills the interior of the closed tube 101.
- the filling material can, for example, be sand, rock, in particular rubble, pieces of a flexible material, such as e.g. made of rubber, but also a liquid.
- the dimensions of the envelope filled with the filling material are selected such that the transverse dimension QA of the envelope 101 represents only a fraction of the longitudinal dimension LA thereof.
- the transverse dimension QA of the sheath 101 can be one fifth of the length LA of the sheath 101.
- the ratio of the dimensions mentioned can vary depending on requirements.
- the material of the casing 101 is designed such that the outside of the casing 101 has the greatest possible coefficient of friction in contact with other materials or objects, in particular with other structural units 100. made possible.
- the outside of the material of the cover 101 can be provided with knobs, projections, etc. This can go so far that the outside of the casing 101 is designed in such a way that it even enables a form fit with other objects, in particular with further structural units 100.
- strips 107 can be attached to the outside of the casing 101, which wrap around the casing 101 transversely to the longitudinal axis A of the filled casing 101 and are firmly connected to it. This can be achieved by sewing, gluing, etc. The transverse strips 107 are spaced apart from one another. The size of these distances can be selected to set a desired size of the form fit.
- the filling material 106 must be introduced into the casing 101, which is normally done by pouring the filling material 106 into the interior of the casing 101. Since the sleeve 101 is relatively long, however, the inside of the sleeve 101 should have the lowest possible coefficient of friction with respect to the filling material 106. In contrast to the outside of the material of the casing 101, the inside of the material of the casing 101 should therefore be as smooth as possible. With a single-layer textile structure as the material of the casing, this can be achieved without great difficulty. Otherwise, the material of the casing 101 can be made in multiple layers for this purpose.
- FIG. 2 shows a front view of a section of the present barrier, which is constructed from a number of structural units 100, which are shown in FIG. 1.
- the structural units 100 are arranged one behind the other in such a way that their longitudinal axes A lie on a common straight line.
- the relevant structural units 100 thus form a row.
- Such rows of structural units 100 run parallel to one another and are arranged next to one another and / or one above the other, so that such rows can form a package.
- One of these rows is arranged opposite another row in such a way that the transition parts lie between the ends of two immediately one behind the other or subsequent units 100 of one of the rows is within the length of one of the units 100 of the adjacent row.
- the structural units 100 of the adjacent rows are arranged offset with respect to one another in their longitudinal direction.
- the structural units 100 of two adjacent structural unit rows partially overlap.
- the means 107 for increasing the friction on the outside of the casing 101 have an effect.
- the transverse stripes 107 also have an effect in this area.
- the present barrier exhibits considerable tear resistance or considerable cohesion in the horizontal direction.
- This cohesion in the horizontal direction cannot be achieved with a barrier or wall composed of previously known structural units, such as sandbags, rubber tires, etc.
- the size of this cohesion of the barrier in the horizontal direction can be controlled by suitably designing the outside of the structural units 100.
- means 108 can be provided which wrap around the package of structural units 100 which are offset and partially overlap.
- These wrapping means 108 can be leather straps, belts, cords, wire, etc. Wrapping means 108 attached in this way not only hold the structural units 100 together, but they also increase the friction between the sections of the structural units 100 lying on one another by pressing the overlapping sections firmly against one another. As a result, the strength or the cohesion of the package from the structural units 100 in the horizontal direction is further increased or increased.
- the individual wrapping means 108 attached to the package are spaced apart from one another, it being immediately apparent that the cohesion of the package in horizontal direction tion, the greater the more wrapping means 108 the package has.
- means 110 can be provided which enable a connection between two structural units 100 arranged one behind the other.
- the simplest possibility for such a connection is shown in FIG. 3.
- FIG. 3 the opposite end parts 102 and 103 of two directly successive or successive units 100 are shown.
- the individual and already described closure means 105 on the structural units 100 are designed or created such that there is a section 119 thereof extending between them.
- the easiest way to do this is, for example, that the connecting means are designed as a single piece of rope which not only wraps around the connecting piece 104 but also connects it to its central connecting section 119 at the same time. •
- FIG. 4 shows a second embodiment of the present structural units 100, which are designed to connect the structural units one behind the other.
- the connecting means 110 comprise a flange 109, the outer diameter of which corresponds to the outer diameter of the casing 101 of the respective structural unit 100.
- the flange 109 has an essentially rigid base body 111, which has the shape of a relatively wide ring.
- a circumferential groove 115 is formed in the respective edge section 113 or 114 of the ring 111.
- the edge parts 112 of the respective casing 101 are slipped over one of the edges 113 and 114 of the wide ring 111 and fastened here in a manner known per se.
- an intermediate piece 116 which is essentially of the same design as the base body 101 of the structural unit 100. Only the diameter of this intermediate piece 116 is somewhat smaller so that this intermediate piece 116 fits into the interior of the casing 101 and can be firmly connected to the casing 101. This can be achieved, for example, by sewing, gluing, etc.
- the free edge portion of the intermediate piece 116 located in the mouth of the sheath 101 is gathered after the filling of the sheath with the filling material 106 in the manner already mentioned to form the socket 1104 and closed with the closing means 105.
- the nozzles 105 thus created can stand freely in the area of the interior of the connecting ring 109 and be arranged at a distance from one another, because the connection of the structural units 100 is ensured by means of the flange 109 via the edge parts 112 of the basic casing body 101.
- FIGS. 5 and 6 show a top view of a first possibility of using the present barrier, which is suitable for absorbing impacts from, for example, racing cars. 6, this barrier is shown in a vertically guided cross section.
- the fact that the structural units 100 are elongated enables curved barriers to be built which have the cohesion mentioned in the horizontal direction.
- the barrier shown in FIGS. 5 and 6 is composed in the described, overlapping manner from the structural units 100 likewise described.
- the structural units 100 are held together by means of the belt 108.
- This barrier is arranged at a distance from one of the dangerous points of a racetrack 125, essentially parallel to the relevant dangerous section of the racetrack.
- Anchoring means are provided for the barrier so that this barrier cannot move under the influence of a car impact.
- the first type of anchoring means comprises anchoring ropes 117, of which the respective anchoring rope 117 is connected at one end to the outer connecting piece 104 of the last of the structural units 100 lying in a row. is. At the other end, the anchoring rope 117 is connected to a peg 118, which is rammed into the ground, for example.
- the anchoring means may further comprise a guardrail 120 embedded in the floor, which is designed in a manner known per se and which is assigned to the side of the barrier facing away from the racetrack 125. In the case shown, the guardrail 120 extends practically over the entire length of the barrier.
- the barrier itself is composed of rows of structural units 100 in the manner already described, the rows of structural units 100 being one above the other and one next to the other.
- the outline of such a barrier can be square in a vertical section. In the case shown, the outline of the barrier is square.
- the rows shown thus consist of the structural units 100 columns K1, K2, K3 and K4 as well as layers L1, L2, L3 and L4. It goes without saying that such a package comprising the structural units 100 can also have a different number of columns and layers.
- the rows from the structural units 100 are held together with the help of the wrapping means 108 already described.
- These wrapping means 108 can be designed as belts with buckles 124.
- the buckles 124 enable quick assembly of the barrier, quick replacement of damaged assemblies 100 in the barrier, etc.
- the barrier can be expediently constructed in such a way that the sleeves 101 of the structural units 100 of the first column K1 directly adjacent to the guardrail 120 are filled with sand.
- the structural units 100 of the two columns K2 and K3 located at a distance from the guardrail 120 are filled with resilient material. These can be rubber pieces or a soft foam, for example, which are located inside the shells 101 of the relevant units 100.
- the units 100 of the column K4 which are most distant from the guardrail 120 can be filled with a liquid. This liquid can be water or an extinguishing liquid. If a car clicks into such a barrier, it first hits the liquid-filled structural units 100 of the outer column K4 facing the race track 125.
- the sleeves 101 of these structural units 100 burst under the pressure of the racing car and this is immediately poured with the liquid which, if a fire occurs, helps to extinguish this fire. What happens after this impact depends on the amount of kinetic energy that the racing cheek still has. Perhaps the carriage is already stopped by the assemblies 100 in the columns K2 and K3, which contain the aforementioned flexible filling 106. Otherwise, the racing car arrives at that column K1, the structural units 100 of which are filled with sand, for example. If the wrapping means 108 have the buckles 124 mentioned, then the damaged structural units 100 can be replaced as quickly as possible by new structural units 100 in the event that another racing car should race into the barrier.
- the barrier can also be used to support bulk material 121.
- the individual structural units 100 can be stacked on top of one another in a manner similar to a pyramid, as is shown in a side view in FIG. 7, in which case they can expediently be held together with the aid of wrapping means 108.
- the material which is denoted by 121 in FIG. 7, could also be water or another liquid, because the barrier, in particular if it is provided with the wrapping means 108, is liquid-tight. It can be seen from the above that the barrier can also have a curved course. This can be exploited in earthworks, for example, if missing parts of the terrain are to be artificially formed in the terrain, especially in the mountains, etc.
- the barrier assemblies 100 are relatively slim and long.
- the sleeve 101 of the respective structural unit 100 is designed as a hose 6.
- 8 shows schematically and as an example a device which is suitable for filling the hose-like structure 6 with sand or another bulk material and which in this way enables the erection of barriers.
- the device for erecting barriers includes, inter alia, a truck 1, which can also be referred to as a source of bulk material 106.
- This truck is shown in FIG. 8 with a body 2 already tilted backwards.
- the device for erecting barriers further comprises an arrangement 5 for filling the hoses for the bulk material 106.
- This arrangement 5 is located in the region of the rear wall 3 of the truck body 2 and is connected to the truck body 2 in such a way that the bulk material 106 from the truck body 2 can get into the arrangement 5. Since bulk goods 106 can only move on their own under the influence of gravity, the present arrangement 5 must be in a vertical or at least steeply inclined position. It goes without saying that the present arrangement 5 can also be used in connection with other sources 1 of bulk material 106.
- the present device is designed such that it enables a controlled filling of the hose 6 with the bulk material 106. It comprises a device 30 (FIG. 9) for receiving the hose 6 to be filled Hose 6 is in a corrugated folded condition when carried by the cradle 30. In this collapsed state, the hose 6 represents a package 7.
- the device further comprises an adapter 10 (FIG. 9), which can be connected to the source 1 of bulk material.
- a nozzle 12 protrudes from the rear wall 3 of the truck body 2 in the example shown.
- the receiving device 30 for the hose 6 to be filled can be assigned to the adapter 10 in the manner described below.
- the adapter 10 has an essentially tubular base body 11.
- This base body 11 comprises a first section or main gate 39 and an extension 41.
- This extension 41 has a tubular base body 42.
- the diameter DF of the extension base body 42 is smaller than the diameter DA of the likewise tubular main section 39 of the adapter base body 11.
- An end section or the upper end part of the extension 41 is assigned to the lower end part or the outlet part 23 of the tubular adapter base body 11, specifically in such a way that the tubes 11 and 42 are arranged coaxially.
- the wall of this transition section 43 has approximately the shape of the shell of a cone.
- the diameter of the larger base area of the cone 43 is equal to the diameter DA of the base body 11 of the adapter 10.
- the transition piece 43 is connected to the adapter base body 11 via this larger end part.
- the diameter of the smaller base area of cone 43 is equal to the diameter DF of extension 41.
- Transition piece 43 is connected to extension 41 via this smaller end section.
- the extension 41 is considerably shorter the adapter base body 11.
- the diameter of the end part of the connecting piece 12 projecting from the rear wall 3 of the truck body 2 is smaller than the inner diameter of the upper end part 9 of the adapter main body 11. Consequently, the free end part of the connecting piece 12 can be inserted into this end part 9 of the adapter main body 11 and this is the result
- Adapter 10 can be connected to the source 1 of bulk material via one of its end parts 9.
- a bayonet or twist lock is expediently used.
- Fastening plates 151 and 152 which have a shaped slot 14 (FIG. 14), are attached to corresponding opposite locations inside the connectable end section 9 of the adapter base body 11.
- the base body of the fastening plates 151 and 152 is curved in accordance with the curvature of the connectable base body end part 9, so that the fastening plates 151 and 152 can rest on the wall of this end part 9 over a large area.
- the slot 14 (Fig. 14) in the respective mounting plate 151 and 152 has essentially the shape of the letter L.
- Leg 16 of the letter L lies in the region of the upper edge 17 of the attachable end part 9 of the adapter 10 and this leg end is open towards the top. This is so that the relevant bolt 131 or 132 can move into the slot 14 through this open end of the vertically running L-leg 16.
- the end part of the horizontally extending leg 18 of the L-shaped slot 14 has a vertically upward extension 19, which is practically perpendicular to this L-leg 18.
- the relevant bolt 131 or 132 can snap into this extension 19 after the adapter 10 has been plugged onto the socket 12 and rotated about its longitudinal axis A by a certain distance.
- the adapter 10 is provided with handles 81 and 82, which are fastened at mutually opposite locations of the adapter base body 11.
- handles 81 and 82 are located in the region of the end part 9 of the adapter base body 11 which can be connected to the connector 12.
- the respective handles 81 and 82 are essentially U-shaped, the free ends of the parallel legs 83 and 84 being fastened to the adapter base body 11 ,
- the leg 85 connecting the parallel legs 83 and 84 runs parallel to the axis A of the device.
- the device 30 (FIG. 10) for receiving the hose package 7 has an essentially tubular base body 31.
- the inner diameter of the tubular main body 31 of the receiving device 30 corresponds to the outer diameter of the main body 11 of the adapter 10 in such a way that the tubular main body 31 of the receiving device 30 can be plugged onto the adapter 10, specifically from the lower end of the adapter 10.
- a bayonet or twist lock is also used here.
- This twist lock comprises connection elements 20, one of which projects from the underside of the lower, parallel U-leg 84 of the respective handle 81 or 82 and is thus directed vertically.
- the respective connection element 20 has a bolt 21 which is attached at one end to the underside of the lower parallel leg 84 of the handle 81 or 82 in question.
- the free end part of the bolt 21 is provided with a head 22.
- This head 22 is flat and has a diameter which is considerably larger than the diameter of the bolt 21.
- the twist lock further comprises means on that end part of the cylindrical base body 31 of the receiving device 30 which is closer to the connection end 9 of the adapter 10.
- the opposite or lower end part of the cylindrical base body 31 of the receiving device 30, on the other hand, is smooth so that the hose 6 can slide off the base body 31 without hindrance.
- Said means enable said positive connection of the receiving device 30 to the adapter 10.
- These connecting means comprise a first flange 33, which is at or as close as possible to the edge or to the edge 17 of the opening of the upper end part of the tubular base body 31 of the receiving device 30 is attached.
- This flange 33 has the shape of a flat ring which is perpendicular to the main axis A of the receiving device 30 and whose inner edge is firmly connected to the upper edge of the base body 31.
- Elongated openings 341 and 342 are made at two diametrically opposite locations of said flange 33.
- the respective opening 341 or 342 has a first and slightly curved section 35, the width of which corresponds to the thickness of the connecting bolt 21.
- An opening 36 with a circular contour adjoins one end of the elongated hole 35. The diameter of this opening 36 is selected such that the head 22 of one of the connection elements 20 can pass through this opening 36.
- connection means on the base body 31 of the receiving device 30 further comprise a second flange 37 (FIG. 9) which is at a distance from the first flange 33 and which runs parallel to this first flange 33.
- the distance between the flanges 33 and 37 is at least so large that the connection heads 22 can find space between these flanges 33 and 37 in such a way that the receiving device 30 can be freely rotated about its longitudinal axis A.
- the second or lower flange 37 serves above all as a stop for the hose 6 surrounding and folding the base body 31 of this device 30. The easily damaged material of the hose 6 should not come into contact with the heads 22 of the connection means.
- the other or opposite end part of the tubular base body 11 of the adapter 10 is provided with means for controlling the outlet of the hose 6 from the adapter 10.
- This control essentially involves firstly preventing the hose package 7 from slipping uncontrollably from the receiving device 30, which is in a vertical or at least inclined position. Secondly, the control mentioned is that sections of the hose 6 do not detach from the hose package 7 in a disordered manner. These controls are essentially carried out in such a way that the outlet of the hose 6 from the receiving device 30 is braked in a suitable manner. 9 shows a first embodiment of such a control device 40.
- the control device 40 is essentially designed as a brake for the hose 6 located in the receiving device 30.
- This brake 40 is located in the area of the extension 41 of the adapter 10. It is assigned to the outside of the extension 41 in such a way that it surrounds the extension 41.
- the braking device 40 is constructed such that the thickness thereof is smaller than the difference between the half-diameters of the base areas of the conical transition piece 43. As a result, the braking device 40 lies within the outer contour of the adapter base body 11, viewed in the axial direction. This offers the possibility of retracting the individual components of the brake 40 so far inward that these components cannot touch the inside of the tubular base body 31 of the receiving device 30 when the receiving device 30 is pushed or plugged onto the adapter 10 from below becomes.
- the braking device 40 comprises wings 461, 462, 463 and 464 (FIGS. 11 and 13), which are arranged on the outside of the extension 41 of the adapter 10.
- the respective brake wing 461, 462, 463 and 464 has a base body 47 which essentially has the shape of an isosceles trapezoid. As can be seen in particular from FIG. 6, the base body 47 of the respective brake wing 461, 462, 463 or 464 is curved outwards or convexly. The axis of this curvature of the base body 4 coincides with the
- Main axis A of the adapter 10 together or it runs parallel to this axis A.
- the respective trapezoidal brake wing 461, 462, 463 and 464 is connected via its shorter base edge 48 to the extension 41 of the adapter 10 so that it can be pivoted and snapped into place.
- This shorter base edge 48 lies in the vicinity of the transition cone 43 of the adapter 10.
- the pivotable connection can be accomplished with the aid of a hinge 49.
- One tab of this hinge is attached to the extension 41 below the transition cone 43 and the other hinge tab is connected to the brake wing 461, 462, 463 and 464 in the region of the shorter base edge 48 thereof.
- the length of the shorter base edge 48 of the trapezoid 461, 462, 463 and 464 is comparable to half the diameter DF of the extension 41.
- the length of the longer base edge 44 of the trapezoid 461, 462, 463 and 464 is comparable to the entire diameter DF of the extension 41. Also thanks to the above Bending of the wing base body 47, the corner portions 51 and 52 of the wings 461, 462, 463 and 464 lying in the region of the longer base edge 44 do not protrude in the retracted state from the outline or floor plan determined by the wall of the adapter base body 11 10.
- the wings 461, 462, 463 and 464 can perform their braking function, there is at least one compression spring 50 between the inside of the respective wing 461, 462, 463 and 464 and the outside of the extension 41, which the brake wing 461, 462, 463 and 464 can push away from the extension with a certain force.
- the compression spring 50 can be designed such that the magnitude of the force with which the wing 461, 462, 463 and 464 act on the inside of the hose 6 coming from the receiving device 30 and can thereby brake it can be changed or adjusted.
- the extended brake vanes 461, 462, 463 and 464 are only required while the hose 6 is pulled away from the receiving device 30 and filled with the bulk material. If, on the other hand, you want to push a receptacle 30 provided with the hose package 7 onto the adapter 10, the extended brake vanes would prevent this manipulation. For this reason, a safety device 53 is assigned to each of the brake wings 461, 462, 463 and 464, which can be designed as a commercially available catch (FIG. 9). The respective catch 53 is arranged in such a way that its slide, which is rounded on the outside, lies in the region of the lower base edge 44 of the respective brake wing 461, 462, 463 and 464.
- the lower wing edge 44 slides on the upper rounded surface of the slide of the catch 53 until it engages behind this slide.
- the emptied base body 31 of the receiving device 30 can be removed from the adapter 10.
- FIG. 15 shows a side view of the adapter 10 from FIG. 9, this adapter 10 being provided with a further embodiment of the braking device 60.
- This braking device 60 is shown in FIG. 15 in a vertical section.
- FIG. 16 shows the main part of the braking device 60 from FIG. 15 in a plan view.
- This braking device 60 is arranged in the region of the end part of the adapter base body 11 lying below or opposite the filler neck 12, specifically below the receiving device 30 for the hose 6. If desired or if necessary, the braking devices 40 and 60 can not only used individually but also at the same time. Because of this last-mentioned possibility, the two braking devices 40 and 60 are shown in FIG. 15.
- the braking device 60 (FIGS. 15 and 16) has an essentially ring-shaped base body 61, which is divided into two halves 611 and 612.
- the length of the respective ring halves 611 and 612 is smaller than the length of a semicircle, so that the ends of the ring halves 611 and 612 assigned to one another are at a distance S1 and S2 from one another.
- the first of the mutually associated ends of the ring halves 611 and 612 are pivotally connected to one another by means of a hinge 62 in a manner known per se.
- the first tab 63 of the hinge 62 is firmly connected to the outside of the first ring half 611.
- the second tab 64 of the hinge 62 is firmly connected to the outside of the second ring half 612.
- the other or second ends of the ring halves 611 and 612 which are assigned to one another are connected to one another with the aid of a tensioning device 65.
- the tensioning device 65 comprises an elongated tab 66, which is attached at one end to the outside of the second end of the first ring half 611.
- One end of a threaded spindle 67 is pivotably articulated on the free end part of this tab 66.
- the tensioning device 65 further comprises an eyelet 68, which is attached to the outside of the second end of the second ring half 612.
- the eyelet 68 is fastened to the second ring half 612 such that the threaded spindle 67 can pass through the opening in this eyelet 68.
- the tensioning device 65 also comprises tensioning means 70, by means of which the size of the first gap S1 can be changed.
- These clamping means 70 consist of a nut 71, which can be tubular, and a handwheel 72, which is integral with the nut 71. By turning the nut 71 in one direction or the other, the width of the gap S1 between the second ends of the ring halves 611 and 612 can be reduced or enlarged.
- the inside of the ring halves 611 and 612 is provided in the illustrated case with brake pads or shoes 731, 732, 733 and 734, which can be made of rubber, for example.
- These brake pads 731, 732, 733 and 734 are in the form of segments of a ring.
- the curvature of the outer wall of the respective brake pad 731, 732, 733 and 734 is similar to the curvature of the inner surface of the respective ring half 611 and 612. This is so that the respective brake pad 731, 732, 733 and 734 is located on the inside of the relevant ring half 611 or 612 can be securely attached.
- two of the brake pads 731, 732, 733 and 734 are each assigned to one of the ring halves 611 and 612.
- the contour of the inner surface 74 of the respective brake pad 731, 732, 733 and 734 represents a circle segment, the radius of the circle in question corresponding to the radius DA / 2 of the cylindrical adapter base body 11 or like.
- this braking device 60 is located below the receiving device 30 for the hose 6 (FIG. 10) and surrounds the lower end part of the adapter base body 11.
- the outer surface of the adapter base body 11 can be further increased in the area this brake device 60 may be provided with a brake layer 69 which extends as a ring surrounding the adapter base body 11 in the area of the brake device 60.
- This brake layer or this brake strip 69 can be made of rubber or the like.
- holding devices 75 are provided.
- the respective holding device 75 comprises a rope 76 which is connected at one end to the braking device 60 via an eye 77.
- the other end of this cable 76 can be provided with a hook or also with an eye, so that this braking device 60 can be suspended on one of the upper flanges 33 or 37 of the receiving devices 30 or on the adapter 10 (not shown).
- the braking device 60 and the empty coil 31 of the previously used receiving device 30 must be removed from the adapter 10. Then you first push the receiving device 30 loaded with the hose package 7 onto the adapter 10 from below and then the brake 60 just described. Now the lower end part of the hose 6 between the brake shoes 731, 732, 733 and 734 on the brake halves 611 and 612 and the adapter base body 11 are passed through so that this hose section is free below the braking device 60.
- the distance of the jaws 731, 732, 733 and 734 from the adapter base 11 is adjusted with the help of the handwheel 72 so that the desired and on the acting on the receiving device 30 pulled hose 6 braking force is reached.
- the magnitude of this braking force can also be changed easily during the filling process of the hose 6 with the bulk material, because the handwheel 72 is approximately at the level of the hand of the person operating this device during the operation of this device.
