Definitions

  • the invention relates to a door runner, preferably provided with a tilt joint, with a door runner body and with at least one disk-shaped anchoring element in the region of its lower end, which has at least one anchoring surface which extends essentially at right angles to the axis of the door runner, the anchoring element being rotated by the door runner body can be brought about its axis from an inactive position, in which it is essentially in the profile of the door runner, into an effective position, in which it projects laterally beyond the profile of the door runner, or vice versa, the anchoring element about an axis is rotatable, which runs parallel and offset to the axis of the door runner, furthermore at the lower end of the door runner a rotatable relative to the door runner body actuating sleeve and a projection are provided which engages in an elongated receptacle of the anchoring element d expects that when the gate rod body is rotated relative to the actuating sleeve, the
  • a gate rail with these features is the subject of the earlier patent application according to the European patent application 305675 of the applicant. It has also been published in U.S. Patent 4,871,279 after the priority date claimed.
  • This well-known gate rail has proven itself in and of itself, especially because the anchoring elements are activated or deactivated by simply turning the gate runner inserted into a snow hole, as a result of which the gate runner is anchored particularly securely in the snow hole.
  • the anchoring is achieved with one hand, namely by the mentioned turning of the gate rail about its axis, which is also very advantageous compared to the prior art at the time.
  • the anchoring plate is provided on a sleeve which is pushed loosely over the lower end of the actual gate runner.
  • the anchor plate is therefore ineffective when the gate rail is rotated about its axis.
  • the anchoring element is designed as a centrically rotatable, lateral extension of the door rail body which can be pivoted under a wedge or out of the profile of the wedge.
  • the wedge serves here as an insertion aid for the anchoring element into the snow hole and it also acts as an anti-rotation device, because rotation between the wedge and the door rod body together with the anchoring element must be achieved.
  • the wedge is not designed as a plate and therefore does not prevent the gate runner from working out of the snow hole.
  • the invention avoids these disadvantages. It is based on the task of proposing a gate runner with the features mentioned at the outset which, while retaining its advantages, remains securely anchored in the snow hole even after prolonged use, even if the skiers have touched the gate runner frequently and possibly with great force.
  • the invention is characterized in that the plate is attached to the actuating sleeve.
  • the gate rail is inserted into the snow hole in such a way that the plane of the plate is essentially aligned so that the plate resists the blows of the racers over the entire surface.
  • the surface of the plate offers such good resistance in the snow that the snow hole on the descents can practically not be enlarged by hitting the racers against the gate runner.
  • the gate rail therefore remains permanently and firmly anchored in the snow hole.
  • the plate can be moved from an active position to a non-active position, or vice versa. You can choose to use the gate rail with or without a plate. For example, the plate can be pivoted up on the actuating sleeve, pushed up or even pulled off completely if you want to deactivate it.
  • the plate extends only on one side of the loosely pushed-on sleeve, it is preferred if, according to the invention, the plate extends on both sides of the door rail and is triangular with a downward-pointing tip. Due to the downward-pointing tip, it can can be easily inserted into the snow and it has a particularly large area because it extends on both sides of the door rail.
  • the plate is displaceable on the actuating sleeve in the longitudinal direction thereof. This makes it easy to adjust the position of the plate on the gate rail to a corresponding depth of the snow hole.
  • the plate has profilings on its outer surface. With the profiles, it grips the snow when the racer strikes, resulting in particularly good anchoring, which also prevents the gate runner from working upwards out of the snow hole.
  • the invention is characterized in another aspect in that latching elements are provided which act between the door rod body and the actuating sleeve and which prevent an unintentional pivoting back of the anchoring element in the activated position of the anchoring element.
  • the latching elements have a ring which has notches on its circumference into which a spring element engages.
  • the side walls of the notches are preferably profiled so that the anchoring elements are prevented from being pulled in without actuating the spring element, while the anchoring elements can be activated.
  • the locking elements work on the principle of the ratchet.
  • this can either be pulled radially outwards with the aid of a handle and / or it is shifted accordingly in the axial direction.
  • Gate rails are usually anchored in the snow using an electrically operated drill. However, this is troublesome, in particular because the diameter of the snow hole created with the aid of the drilling machine does not match the outer diameter of the lower end of the door runner. A drill steel of the appropriate thickness can be chosen for this, but there is also the danger that the snow hole just created will at least partially fall back with snow.
  • the invention furthermore proposes to use a piece of pipe pushed over the lower end of the door runner to hold the door runner in the snow hole , wherein the pipe section has an external thread and has at its upper end means for releasably connecting the pipe section to a drill steel of a drilling machine.
  • the pipe section has an external thread and has at its upper end means for releasably connecting the pipe section to a drill steel of a drilling machine.
  • the connecting means are designed in the manner of a bayonet lock.
  • the drills have a cross pin spaced from their lower end and the cross pin is inserted into the bayonet catch.
  • this has an L-profile at the upper end of the pipe section, to one or both sides, depending on whether you want to use the device only when screwing in or also when unscrewing.
  • the single or double L-profile can have an angle at the end of the aisle in such a way that it creates a locking point for the cross pin.
  • the plate already described can also be used with advantage in conventional door runners, in which case it is based on the task of securely anchoring the relevant gate bar in the snow hole.
  • the invention is characterized in a further aspect in that a plate for anchoring the gate rail in the snow is preferably detachably and non-rotatably connected to the lower end of the door rail, the plate plane of which runs essentially parallel to the longitudinal extension of the door rail.
  • the plate can be brought from an active position into a non-active position, or vice versa, as described above.
  • the plate extends on both sides of the door rail and is triangular with the tip pointing downward.
  • the plate is displaceable in the longitudinal direction of the door rail.
  • the plate has profilings on its outer surface.
  • the advantages of a gate runner equipped with this plate are that the plate, due to its large area, exerts a great resistance which prevents the gate runner from working out of the snow hole, even after the gate runner has been used for a long time, for example in a race. You can then choose between door rails with or without a plate equip. This is preferably done with the help of a dovetail guide, over which the plate is pushed in the direction of the longitudinal extension of the door running bar onto a corresponding profile on the door running bar.
  • the basic structure of the gate bar according to the invention is as described in US Pat. No. 4,871,279 or also as described in US Pat. No. 4,702,639, so that it need no longer be discussed. But it can also be conventional gate rails Find use, ie without anchoring elements that can be swung out.
  • FIG. 1 shows a door runner bar designated as a whole with item 1, which can be equipped with or without anchoring elements. These are not shown in the drawing in FIG. 1, but are shown in FIGS. 2 and 5.
  • the gate rail 1 is preferably equipped with a tilt joint 2.
  • a plate 3 is attached, which can be trapezoidal, as shown in the drawing, or triangular with the tip pointing downward.
  • the plate 3 is screwed to a sleeve 4, which in turn is fastened to the gate rail 1.
  • fastening possible, in particular those in which the plate 3 can be pivoted upward about its upper edge into an inactive position, or also a fastening via a dovetail connection, so that the plate 3 is displaced in the longitudinal direction of the gate rail 1 can.
  • FIG. 2 shows a gate running rod 1 with anchoring elements 5 attached at its lower end, which are pivotably mounted in slots 6 of a gate running rod body 7.
  • the gate runner body 7 is integrally connected to the upper part 8 of the gate runner.
  • a sleeve 9 can be rotated relative to the gate runner body 7, 8, with the anchoring elements 5 then can be swiveled out of the profile of the door runner or swung back in again.
  • a latching device in the manner of a ratchet which consists of a ring 10 shown in FIG. 3 and a spring indicated at item 11.
  • the ring is attached to the gate rod body 8 and the spring to the sleeve 9, or vice versa.
  • the ring has depressions 12 on its circumference, which form the latching position for the spring 11, which is inserted into the depressions.
  • FIG. 3 also shows that at least one of the depressions 12 has a gently rising wall 13 in one direction of rotation and a steeply rising wall 14 in the other direction of rotation.
  • the spring 11 can be pivoted outwards in the direction of the arrow 15 in order to disengage it from the teeth or recesses, or downwards in the direction of the arrow 16.
  • FIG. 4 shows a pipe section 17 with an external thread 18.
  • a drill steel 19 of a drill is inserted into the pipe section, the thread turns of which are indicated at item 20.
  • the drill steel has a cross pin 21 which engages in a corresponding recess 22 on the upper edge of the pipe section 17.
  • the piece of pipe is placed on the drill steel, as shown in FIG. 4.
  • the drill is then actuated and the snow hole is made, which is easily possible with the help of the external thread 18 of the pipe section 17.
  • the pipe section and the Drill steel connected to one another in a rotationally fixed manner via the connection 21, 22. Then you pull the drill steel out of the pipe section and you can now insert a gate rail 1 into the pipe section, which is already anchored in the snow hole and the inside of which is free for inserting the gate rail.
  • Fig. 5 shows the possibilities described on a single door rail 1, namely again the pivotable anchoring elements 5 at the lower end of the door rail, above the pipe section 17 with its external thread 18 and above the plate 3, which also indicates that the plate on it Has outer surface horizontally extending corrugations or profiles 23 with which it is pressed against the snow.
  • the recess 22 can be T-shaped. The lateral ends of this profiling can also point upwards, in order to create locking points for the cross pin 21.
