    The present invention relates to a hedge for hedge running with two hollow bases (1) arranged at a distance from each other and which are intended to rest on a base, a counterweight (25) being slidably arranged in each base (1), and that in relative to the base vertical tubular elements (2, 3) are fixed at one end of each subcarriage (1), each tubular element consisting of two telescopically relatively displaceable tubes (2 and 3, respectively), means (9, 10, 13, 15) to lock the telescopic tubes (2, 3) relative to each other, and that a rib (4) connects the upper ends of the tube (3) having its upper end located furthest from the associated chassis (1). Characteristic of the hedge according to the present invention is that a band-shaped power transmission means (20) extends from the hollow space in each chassis (1) up to the associated pipe element (2, 3), that the air transmission means (20) is connected to the pipe (3) which supports the bar (4), that a gear transmission device (22, 23, 40) is arranged in each of the chassis (1), and that the gear transmission device (22, 23, 40) engages partly with the band-shaped power transmission means (20), partly with a carrier means (21) for the counterweight (25).

    30 2 mistakes are placed in the wrong position. Refers to U.S. Patent No. 4,749,187 where the counterweight can be displaced by means of a wire one end of which is fixed in the upper telescopic height and lowerable tube and passes inside the lower corner of the hedge perpendicularly backwards via a folding wheel.
    Vajem then passes next to the counterweight, turns via another folding wheel at the back inside the foot and turns again via a folding wheel at the back of the counterweight to then be fixed at the back inside the foot. This means that when the bar is lifted upwards, the counterweight is moved backwards with a fixed gear, which means that it moves half the distance that the bar has been moved in height. In order for the counterweight to be able to move forward when the bar is lowered downwards, a drawbar is mounted between the front edge of the counterweight and inside the lower and upper corners of the hedge. Since the same type of device is on both sides of the hedge, this means that two springs must be pulled out when the bar fl is extended upwards, which in its mr means that a very large force is required to move the bar upwards, especially to its uppermost position when the springs have been maximally extended. . Another constructive disadvantage is that the counterweight fl is flattened exactly 50% of the distance at which the slat is flattened, which can make it difficult to obtain an exactly equal tipping resistance regardless of the height of the slat. A more optimal gear ratio for constant tipping resistance means that the counterweight should move about 60-70% of the distance that the bar fl is flattened in height.
    Also refers to a Japanese patent application no. JP82996l 5 which also describes a hedge with automatic movement of the counterweights but according to what the pictures in this application show, the counterweights are moved in the wrong direction, which means that the desire for constant tipping resistance cannot be fulfilled. The gear transmission is located in the vertical pipes where there is normally a lack of space to then transmit the force perpendicular to the counterweight via a wire. A wire in a wire casing is usually good to pull with but works worse when you need to push a force fi forward with a wire end outside its casing and then especially a longer distance, normally for a hedge about 200-250 mm means that the wire bends or deformed.
    Aims and features of the invention An object of the present invention is to provide an automatic hedge where the bar can be moved upwards or downwards with a relatively small force which is constant throughout the movement.
    Another point of view of the present invention is that the gear ratio between the movement of the bar and the counterweights can be chosen in connection with the manufacture substantially steplessly in order to achieve as precise a tipping resistance as possible for the different heights at which the bar can be located.
    Another object of the present invention is that the hedge should be constructively simple so that the manufacturing cost can be kept low. Brief Description of the Drawings Fig. 1 shows a side view of the hedge; Fig. 2 shows a view from the rear of the hedge, seen from the hedge runner; Fig. 3 shows a top view of the hedge; Fig. 4 shows a partially sectioned side view of Fig. 3 through A-A with the bar in its uppermost position; Fig. 5 shows a partially sectioned side view of Figs. 3 through A-A with the bar in its lowest position; Fig. 6 shows an enlargement of the upper parts of the hedge from Figs. 4-5 with the locking mechanism in locked position; Fig. 7 shows an enlargement of the upper parts of the hedge from Figs. 4-5 with the locking mechanism in free position; Fig. 8 shows a rear view of the top one corner of the hedge; F ig. Fig. 9 shows an enlargement after B-B of Fig. 4; F ig. 10 shows an enlargement of the corner detail 17 and a part of detail 20; Fig. 11 shows a top view of detail 20; Detailed Description of a Preferred Embodiment of the Hedge of the Present Invention The hedge shown in Figs. 1-3 comprises a tubular base 1, called a foot, which rests on the ground and a vertical tube 2 which is fixed at the front end of the foot 1. Partially above tube 2 rör nns tube 3 which is telescopically raised and lowered and forms a bracket for the bar 4 which is thus raised and lowered. These parts together form the shape of an L seen from one side of the hedge whose two sides are built up in the same way and are firmly connected to each other at the bottom through the crossbeam 5 and at the top of the rib 4.
    The hurdles runner runs towards the hurdles from left to right according to F ig. In to skip the bar 4.
    F ig. 4-5 include the same details with the bar at the highest height in Figs. 4 and at the lowest height in Fig. 5. The figures also show i.a. how the counterweight 25 in the foot 1 is in the rear position, i.e. to the left when the bar is at a high height, and in the front position, to the right when the bar is at a low height so that the tipping resistance is the same regardless of the height at which the bar is.
    The following detailed description of the function describes only one side of the hedge while the same things are affected and happen in the same way on the other side of the hedge which is built in the same way: Fig. 6-8 shows when the bar is to be upp moved up or down, grab the bar 4 with your hand and at the same time let a finger lift something on the handle ball 32 which is fixed in the movable pin 27 which is height and lowerable and movable sideways in its top position via the opening 12 on 10 15 20 25 30 35 4 one side of the tube 3. The drawbar 6 is then lifted upwards a few mm whereby the locking arm 15 with its locking pin 9 fi opens the upper tube 3 from the locked position so that the tube 3 with the bar 4 can be raised or lowered .
    The locking arm 15 is rotatable via its welded tube 14 which is rotated about a shaft 34 which is fixed in the tube 3. The flat bar 7 which is welded together with the internally threaded rod 16 is fixed in the tube 2 via the screw 35. The flat rod 7 has at least 5 holes 13 through for locking the various fixed height positions by means of the locking pin 9 which is pressed into one of the holes. Because the flat bar 7 with its holes 13 is arranged inside the pipes 2, 3, no dust or dirt can enter the pipes 2, 3 via the holes 13 which are hermetically enclosed by the pipes 2, 3. The opening 12 in one side of the upper pipe 3 restricts the upward and downward movement of the pin 27 with its handle ball 32 but also makes it possible in the upper position to move the pin 27 perpendicular laterally towards the bar 4 to stay in that position so that one can move the bar vertically without having to holding the handle ball 32. When the handle ball 32 is then folded back laterally in the direction of the rib 4, the locking bar 15 will, with the aid of fi force fi from the tension spring 10, insert the locking pin 9 into the flat bar 7 as soon as the bar 4 has been moved vertically so that the locking pin 9 hits one of the approx. 5 holes 13 in the flat bar 7, the height adjustment of the bar being in a locked position. At the same moment as locking, the handle ball 32 is also pulled to its lower position by the drawbar 10 whose upper end is fixed in the lower part of the drawbar 6 and the lower end of which is fixed in the screw 11 which is fixed at the bottom of the tube 3. The drawbar 6 operates the locking lug By the nuts 42-43 being fixed to the drawbar 6 with a certain play between the respective nut and the locking arm 15.
    A power transmission means in the form of a steel strip 20 (see Fig. 11) is made of a thin, easily bendable stainless steel with a thickness of about 0.4 mm and a width of about 35 mm.
    The bead transfer means is flexible only in a plane seen perpendicular to the paper in Fig. 11. Its one end is screwed through the holes 30 with the screws 31 in the lower part of the raised and lowered tube 3 and the power transmission means extends downwards between the flat bar 7 and one of the inner walls of the lower vertical tube 2. Then further via a radially formed guide 17 with an inner radial guide 19 and an outer radial guide 18 which provide a suitable bending radius for the power transmission means 20 for minimal frictional resistance. Then the collar transfer member runs further back in the foot 1 and is guided this entire horizontal distance both upwards, downwards and laterally by the guides 24 and 28 which in this case are part of the pipe profile 1 which can be manufactured by extruding aluminum. The rectangular holes 29 (Fig. 11) which are punched in the force transfer means 20 together provide the function of a flexible transmission as well as the function of a rack by the teeth on the gear 23 partially passing through the holes 29 so that the gear 23 rotates when the crate transmission means 20 moves.
    When the rib 4 and the upper tube 3 with its constituent part fl are moved upwards, the horizontal part of the crate transfer member 20 moves to the right, the gear 23 rotating counterclockwise.
    The smaller gear 22 which is joined to the gear 23 and rotates about the same axis 40 then drives the rack 21 together with its test plate 26 with the counterweight 25 in the direction to the left a shorter distance than the distance which the bar dares to be flattened upwards. The difference between the distance that the bar is to be flattened and the shorter distance that the counterweight is to be flattened can be easily adjusted by selecting the difference in diameter of the two gears 22 and 23 to get as constant a tipping resistance as possible between the highest and lowest set height of the bar. Fig. 4 shows the position 20a of the end of the power transmission means 20 when the bar is in its highest position and Fig. 5 shows the position 20b of the end of the power transmission means 20 when the bar is in its lowest position.
    The stop lug 8 which is fixed in the flat bar 7 prevents the tube 3 from being lifted too high by the tube 14 receiving the stop lug 8 when the bar 4 is at the highest adjustable height.
    The counterweight 25 and the mounting plate 26 function together as a total movable counterweight which together weigh about 2.5-3 kg. The counterweight 25 slides on top of the profiles 24 and 28 belonging to the tube 1 with a distance in between consisting of a fuel material 44 which is attached below the counterweight and which slides easily on top of the profiles 24 and 28 (belonging to the tube 1).
    The screw 33 prevents the rack 21 from being lifted upwards and thereby losing contact with the gear 22.
    Positions 36-38 are cover caps in this case made of plastic which protect the contents of the pipes against dust and moisture.
    A storage of plastic 39 which is square and hollow functions together with four plastic washers 41 as bearings between the pipes 2-3. Only two of the four plastic washers are shown in Figs. 4-7 so as not to obscure the lower part of the tension spring 10. Each of the washers 41 is fixed in the lower part of the tube 3 on all its four sides.
    Possible modifications of the invention The power transmission means 20 which in this case consists of a metal strip of so-called fi stainless steel with a thickness of about 0.4 mm can also be thought to be made of a slightly higher plastic material and then probably with a slightly increased thickness.
    The rectangular holes 29 in the power transmission means 20 may also be replaced by protruding teeth adapted to some kind of gear which in that case replaces the gear 23.
    The rack 21 and the gears 22-23 are in this case made of plastic but can also be made of some kind of metal.
    The counterweight 25 has a sliding bearing 44 consisting of a ltin material. The material can be replaced with any other material that slides easily against the surface. Many types of plastics can handle this
