Definitions

• the present invention relates to a device according to the preamble of patent claim 1.
• the disadvantage of this barrier is that the strand at the weighted end sinks first, increasingly takes on a diagonal position and only gradually lies on the traffic area from this end to the other end. This forces an automobile operator to pay the greatest attention so that he does not run over the barrier too early, so that the strand gets tangled with the vehicle. In the lowered position of the strand, it is not stretched from post to post. It hangs on one of the Post down under the load of the weight, whereas it hangs loosely down on the other, drive-side post. It can therefore be moved in the direction of travel and can be carried along by a vehicle when it is driven over.
• the present invention therefore has as its object to eliminate the disadvantages mentioned in a barrier of the type mentioned, in particular to improve such that the strand can be raised and lowered substantially uniformly over its length.
• Fig. 1 is a front view of a barrier
• Fig. 2 is a plan view of Fig. 1;
• FIG. 3 shows a section along the line III-III in Fig. 1.
• Fig. 4 is a section along the line IV-IV in Fig. 1;
• Fig. 5 is a plan view of the entire drive and control unit carrying

• FIG. 7 shows the view X according to FIG. 6
• FIG. 8 shows a weight body in the form of a weight roller
• Fig. 9 one half of the picture for fastening the post in the ground.
• Posts 2 and 3 are permanently mounted in a vertical position.
• Posts 2 and 3 consist of a square hollow profile and each have a fixed stop 4 or 5 on the inside, from which a vertical slot 6 extends downward to the post base on the facing side of the posts in the post jacket.
• the end of the strand 8 is fastened in the form of a rope which partially loops around a loose weight roller 9 and extends from there horizontally to the other post 2.
• the rope can also be fastened to the anchoring point 7 with the aid of a clamping screw. Since the upper ends of the posts 2, 3 with a releasably attached, for. B. screwed, cover are closed and the anchoring point 7 is preferably located in the upper region of the post 3, said clamping screw is easily accessible at all times and thus the strand 8 can be easily removed from the anchoring point 7 accordingly.
• the strand 8 also partially wraps around a loose weight roll 10 and is guided from there to a winding drum or storage roll 11 on which it can be wound up or unwound.
• the storage roller 11 is mounted on the carrier plate 12 of a control and drive unit 13 which is interchangeably mounted in the post 2 from above and is connected to a low-voltage motor 15 via a gear 14.
• the motor 15 can be actuated by means of a preferably remote-controlled control 16.
• the weight rollers 10, 11 are freely movable in the posts 2 and 3 and carried by the strand 8. If the strand 8 is wound onto the storage roller 11, the weight rollers 9, 10 bear against the fixed stops 4 and 5, which determine the span height of the strand 8 which it occupies when the traffic area 1 is closed.
• the weight rollers 9, 10 move downward under the influence of gravity until they strike the bottom of the post 2 or 3 (position 10 'or 9') and the strand 8 on the traffic area 1 rests. At this moment the motor 15 is stopped and the strand 8 is held between the weight rollers 9, 10 without play.
• the weight of the weight body in the second post 3 in the form of the roller 9 can, if required, be chosen to be greater than the weight of the roller 10 in the first post 2.
• the carrier plate 12 carrying the drive and control unit 13 is shown in detail in FIGS. 5 to 7. It has an essentially rectangular plan with an essentially rectangular recess in its left central area and is made of aluminum. At the lower end of the carrier plate 12 is the gear 14 with two from the plan level (it is thus the projection plane 5), the projections 40, 41 projecting from the support plate 12 are screwed together.
• the output shaft 42 of the transmission 14 protrudes perpendicularly out of the plan of the carrier plate 12 and engages in a corresponding receptacle on the storage roller 11 in a rotationally fixed manner.
• the essentially cylindrical low-current motor 15 is detachably mounted on the gear 14 so that it does not have to be mechanically attached to the carrier plate 12. It is placed in the recess in the left central area of the carrier plate 12 so that it does not protrude from the rear 29 of the carrier plate 12.
• the electrical or electronic control elements 30 are arranged at the upper end of the carrier plate 12. They are detachably connected to a mounting plate 43 running perpendicular to the plane of the base plate 12. This mounting plate 43 is preferably pressed into the carrier plate 12.
• the control elements 30 are thus easily accessible from above and can in particular be easily removed without having to remove the entire support plate 12 from the post 2.
• Corresponding power lines 25, 26 run through openings in the fastening plate 43 for connecting the control elements 30 to the low-current motor 15.
• the mounting of the carrier plate 12 into the hollow profile of the post two takes place after the cover 2 closing the post 2 has been removed by simply inserting the carrier plate 12 into the post 2. This insertion is preferably carried out from above, but can also take place from the side, provided a corresponding side cover is provided is.
• the motor / transmission unit 15/14 and the storage roller 11 must be mounted on the carrier plate 12 beforehand.
• the carrier plate 12 is held by two laterally protruding bearing surfaces 27, 28, which rest on corresponding shoulders, shoulders, projections or the like at the upper end of the post 2.
• the carrier plate 12 is additionally clamped in the hollow profile of the post 2 with the aid of a locking plate 35, which is also preferably pressed into the carrier plate 12.
• the locking plate 35 is arranged in the right central region of the carrier plate 12 and, like the fastening plate 43, extends perpendicular to the plan plane of the carrier plate 12. It extends essentially from the inner wall of the square hollow profile, against which the rear side 29 of the carrier plate 12 rests this inner wall of the hollow profile opposite wall.
• the actual clamping of the support plate 12 in the post 2 then takes place with the aid of a screw rotatably mounted in the threaded bore 44 with an eccentric head, the eccentric part of this screw head accessible from above being adjusted so that the locking plate 35 and thus the support plate 12 between the Walls, between which the locking plate 35 extends substantially, is clamped.
• the back 29 of the carrier plate 12 which has no projections, bears against the inner wall of the square hollow profile, which lies opposite the wall to which the rotatable clamping element engages with an eccentric head.
• the carrier plate 12 enables particularly simple handling, since it carries the complete drive and control unit 13.
• the motor 15 can be designed as a low-voltage direct current motor, which drives the storage roller 11 and keeps the strand 8 tensioned in the upper end position with reduced power.
• Weight roller 10 in the post 2 is in the area of the lower edge surface 33 of the support plate 12 on the
• Carrier plate 12 arranged. It is particularly advantageous and simple if the lower edge surface 33 itself is used as a stop.
• FIG. 7 shows a partial view of the rear side 29 of the carrier plate 12 in its lower region.
• a recess 45 is incorporated in this area of the rear side 29, in which a limit switch 34 is arranged, the actuating element 46 of which projects downward from the lower edge surface 33 of the carrier plate 12. If the weight roller 10 now reaches the lower edge surface 33 acting as a stop in the final phase of winding the strand 8 onto the storage roller 11, it actuates the limit switch 34 with the aid of the actuating element 46, which in turn causes the low-current motor 15 to be switched off with a certain time delay .
• a groove 47 is arranged on the back of the carrier plate 12, as shown in FIG. 7, between the recess 45 and the rectangular recess in the carrier plate 12 for the low-current motor 15 , in which corresponding electrical cables can be inserted.
• the motor / gear unit 15/14 has a worm / worm gear toothing which is provided with such an internal static friction that it is not possible for the strand 8 to have the gear 14 alone to operate due to its weight.
• the gear 14 is thus designed to be self-locking; the strand 8, however, can give way to a violent pressing down by hand, which also prevents damage here.
• This z. B. also abuse of strand 8 by children playing, z. B. as a swing prevented.
• the weight roller 10 in the drive-side post 2 moves away from the limit switch 34, which then automatically starts the low-current motor 15 in order to bring the strand 8 back into its upper end position.
• Low-voltage direct current gearmotors are particularly suitable as motor / gearbox unit 15/14 (e.g. type 403 287 from the 0223 series from A. Ott in Deisslingen; nominal voltage: 24 volts, self-locking up to 1.2 Nm) .
• Such worm geared motors are also characterized by excellent low noise.
• the transformer required for the operation of the shut-off device which is the usually available 220 volt alternating current z. B. transformed into 24 volt direct current, is preferably housed in an adjacent building. The fact that low-voltage power is used here means that the safety requirements for laying the supply line between the building and the shut-off device are comparatively low.
• the transformer heats up and a fuse housed in it in the form of a non-self-destructing thermocouple switches off the power supply when a certain temperature threshold is reached. When the temperature drops below this threshold value due to cooling, the power supply is switched on again and the winding process continues accordingly.
• the strand 8 is preferably encased with pipe sections 17 lined up thereon.
• These pipe sections 17 preferably have an elliptical or oval cross section.
• the elliptical pipe sections 17 lie flat on the floor and can be run over without vibration. This is particularly the case if a groove of small depth and of such width extends in the traffic area 1 from post to post that the pipe sections 17 disappear therein flush with the traffic area 1.
• the smallest diameter of the oval tube sections 17 is also greater than the width of the slots 6 in the posts 2 and 3. As a result, the tube sections 17 are guided vertically exactly between the posts and move vertically up and down between them, analogously to a horizontal bar.
• the weight roller 9 (the weight roller 10 is constructed analogously) consists of three dumbbell-like rollers 19 to 21 placed on a shaft 18, of which the roller 21 has a smaller diameter than the adjacent rollers 19 and 20 . This results in perfect guidance the weight roller 9 in the post 3 and the strand 8 can not jump out of the rollers even in a loose state.
• FIG. 8 An alternative embodiment of the weight rollers 9, 10 is shown in FIG. 8.
• the weight roller shown there consists of a heavy cylinder 37, preferably made of steel, a cylindrical sleeve 36 and two end plates 38, 39.
• the Sleeve 36 on a slight radial clearance with respect to the cylinder 37 and is rotatable relative to this. This is particularly advantageous in the case of the drive-side weight roller 10, since the strand 8 then does not bite into the sleeve 36 during the overrun described above and can form corresponding circumferential depressions there, since the sleeve 36 rotates relative to the cylinder 37 and thus does not form one Frictional relative movement between the strand 8 and the sleeve 36 can arise.
• the cylinder 37 is in each case pressed into the corresponding cylindrical openings in the end plates 38, 39.
• the circumferential surfaces of the cylinder 37 covered by the end plates 38, 39 can be knurled to improve a rotationally fixed connection between the end plates 38, 39 and the cylinder 37. Furthermore, an axial play is left between the end plates 38, 39 and the cylinder 37 on each end.
• Both the sleeve 36 and the end plates 38, 39 are made of a plastic which is low-friction compared to metal, in particular aluminum.
• the stable arrangement of the posts 2, 3 can be accomplished in cases in which a special mobility of the locking device is required with the aid of a conventional parasol stand onto which the posts 2, 3 are attached.
• the solutions according to FIG. 9 can be used, for example.
• a ground sleeve 48 is first concreted into the ground by means of concrete 49.
• Fig. 9 shows a base 50 which e.g. can be screwed to the concrete 49 using dowels.
• the base 50 has an upwardly extending post that supports it
• Bores 53 in the post walls can thus adjust the clear post length, ie the length of the posts 2, 3, which protrudes from the ground, and thus the span of the strand 8.
• the base 50 as well the ground sleeve 48 naturally have the same cross-sectional shape as the posts 2, 3, but with somewhat larger dimensions in order to ensure the displaceability of the posts 2, 3 accordingly.
• FIG. 9 A further possibility for anchoring the posts 2, 3 in the ground is shown in the right half of FIG. 9.
• at least one elastically resilient snap element 54 e.g. B. an elongated piece of steel strip attached.
• the snap element 54 is fastened to the post 2 or 3 with at least one fastening element 55.
• This attachment can be detachable, but also not non-destructively detachable, e.g. B. riveted.
• a snap head 56 At the other end of the snap element 54 there is a snap head 56 which projects outward from the snap element 54 with respect to the hollow profile.
• the snap head 56 On the side of the snap head 56 facing away from the snap element 54, the snap head 56 has a bevel 57 which, viewed in the vertical direction, runs towards the center of the hollow profile. Furthermore, an opening 58 is arranged in the profile wall of the post 2, 3 at a location which lies between the fastening element 55 and the snap head 56 and is covered by the snap element 54. Through this opening 58, the snap element 54 can be reached from the outside and pressed resiliently into the interior of the profile. When inserting the post 2, 3 into the base sleeve 48, this is required to a lesser extent, in contrast to pulling it out, namely only until the bevel 57 on the snap head 56 pushes the snap element 54 away by itself by further vertical insertion of the post 2 or 3 supports.
• the snap head 56 is dimensioned such that the entire slope 57 through a second opening 59 in the profile wall of the post 2, 3rd protrudes through the profile wall. The result of this is that the snap head 56 snaps into an opening 60 in the base sleeve 48 exactly when it is aligned with the second opening 59 in the profile of the post 2, 3.
• the post 2, 3 is then supported in the vertical direction by the bottom surface of the snap head 56 resting on the horizontal surface in the opening 60.
• the posts 2 or 3 can be released from the base sleeve 48 at any time by pushing the snap element 54 through the opening 58 in the direction of arrow A.
