Definitions

• the present invention relates to a locking device for boundary and goal bars, in particular for goals of ski sports according to the preamble of claim 1.
• Flexible rods used to date have, as anchoring unit in the snow, a plastic tip, which is driven by means of a key into the snow, eg artificial snow.
• a hole is removed in the snow by means of a ⁇ pira 1 drill.
• the especially flexible rod at the tip of the rod is screwed into this hole.
• the loosened snow means that the thread from the outset does not come on optimal way into engagement.
• the anchoring unit consists of a hexagonal or round section with flexible brushes projecting thereon. In this case, a hole is excluded and then it is sufficient to plug the flexible rod into the snow. Experiments have shown that more or less forms a secure anchorage. However, this system is difficult to dismantle by drilling holes next to the square bar to loosen the snow and loosen the bar, drilling too close to them anchored in the snow Brushes, these are wound up and damaged by the drill.This system is more or less fast to build, but can be broken down only with great expenditure of time.
• European Patent EP 0 305 675 B1 discloses a door running bar with at least one disc-shaped anchoring element in the area described its lower end, which has at least one anchoring surface which extends substantially rectangular to the axis of T or 1 on rod, wherein the anchoring element by rotation of the door running bar about its axis in an inoperative position in which it is substantially in profile the door running bar can be brought into an operative position in which it protrudes laterally beyond the profile of the door or vice versa.
• Anchoring element is rotatable about an axis that runs parallel and offset from the axis of the door opening. Because of the off - center movement of the
• Rod axis the rod itself tends to widen the bore and therefore loosen the snow, thereby degrading the stability of the anchorage itself.
• European Patent Application EP 0 385 295 also describes a rod as described in the above-referenced patent, in which, moreover, in the region of its lower end, a pivoting mounting sleeve rotatable relative to the rotor is provided, as well as a projection , which engages in an elongated receiving the anchoring element, such that upon rotation of the
• the control unit is not activated or deactivated.
• the Torlauf rod is a plate for anchoring the T or 1 rod in the snow provided, the plate plane is substantially parallel to the L Lucasser st stretching the rod.
• the plate is attached to the mounting bracket. In this case, however, the plate serves at the same time to actuate the

• This task is performed by a
• the lifting device consists of an alternately on the core or on the expansion sleeve provided cam, such that the
• Expansion sleeve can be adjusted relative to the core.
• the lifting mechanism consists of a bolt which extends transversely to the longitudinal axis and moves upwards on rotation on a contour-like contour on the outer sleeve.
• a downward movement of the rod is necessary to activate the anchoring task.
• the new system is activated by moving the rod upwards.
• only a quarter turn is necessary to get the desired effect.
• This has the advantage that there are no unwanted reciprocating movements, ie within the levels occupied by the axis of the rod during activation, which loosen the snow.
• the activation of the system takes place in that the conical part of the inner core spreads at least two sections of the outer sleeve.
• the lamellae on the outer shell engage the snow and effect the actual consolidation / release in the snow. If you want to disable the mechanism, it is sufficient to rotate the inner core with the actual rod vice versa. The rod moves down and the resulting only in the activation in the portion of the outer shell voltages return them in a spring back to their on fangsposition.
• the at Deacti vation could hinder the closure of the sub-areas of the outer shell, it is advantageous to previously install in the respective spaces between the protruding slats a rubber-like ring as a bicycle tube, which has the advantage that these rings at the de aktiie run g the return of Side areas of the
• the elevator consists of a ramp in the region of the core head that extends alternately from the core head about the axis of the core and acts on the corresponding end of the expansion sleeve to compress it with rotation of the head z or to spread.
• the rod including the ski-mounted inner core
• a cam which is alternately provided on the core or on the sleeve, for example in the form of a wedge.
• the partial areas of the outer shell open by being spread open, and the lamellae existing on it anchor themselves in the snow.
• the system is activated this way.
• the system is deactivated and the rod can be easily removed by providing inclined planes in the direction of the axis of the core head, which guide the sleeve in the direction Press the axle itself, so the lamellae are freed from the snow.
• the benefits are significant.
• the system forms a structural unit that contains no loose part, can most of the z. 2. systems adapted to the market.
• the system itself is activated by moving the rod upwards together with the inner core.
• the system is deactivated by moving down the bar. Further details and features will become apparent from the claims and from the following description of a preferred, illustrated in the accompanying drawings embodiment. Show it,
