Definitions

  • the invention relates to towing lift systems for skiers and snowboarders, in particular to devices designed to direct the yoke bar to the landing site and limit its free vibration, and can be used to equip ski slopes.
  • a rope tow is a commonly used piece of equipment for towing skiers and snowboarders uphill and generally includes supports located along the route that carry a tow rope that is closed in a circle and driven by an electric drive. So-called cables are attached to the tow rope evenly along its entire length. yokes, clinging to which skiers and snowboarders (hereinafter referred to as users) climb the mountain.
  • the yoke typically includes an inertial drum with a tow rope, to which a tow bar is attached in the shape of an inverted "T". This yoke is designed to tow one or two people.
  • the main difficulty in using a rope tow is related to landing. You need some skill to sit on a yoke moving along a ski slope, and even with skis or a snowboard on.
  • the lift can be equipped with a special guiding device designed to guide the yoke bar to the landing site and limit its free vibration.
  • the patent FR2127475 (published on October 13, 1972) describes a guide device for a rope lift, made in the form of a stationary frame structure having an input and output part for a towed rope rope.
  • the yoke rod falls into the guides, is captured by conveyor belts driven by pulleys connected to an electric motor, and moves towards the output part of the device.
  • catchers are installed that receive the yoke rod, preventing its further movement until it is removed from the catchers by a user ready for towing or pulled out by a force that increases as the lift cable moves.
  • height-adjustable supports are provided to adjust the height of the catchers relative to the surface of the ski slope.
  • the patent DE7213029U (published on March 22, 1973) describes a guide device for a rope tow lift, made in the form of a stationary structure installed at the users’ starting point.
  • the device contains two guides suspended on a stationary support above the level of the user's head, diverging from the input side to receive the yoke rod. As it passes between the guides, the yoke rod is slowed down due to frictional forces, and at the exit, due to springs compressing the guides towards each other, it essentially stops until it is either pulled out by the user, or it is pulled out by a force that increases as the lift cable moves. .
  • Application DE2121651A1 (published on November 23, 1972) describes a guide device for a yoke lift, made in the form of a stationary frame structure having two guides, made at the entrance in the form of a collecting fork that grips the yoke rod.

  • This solution can be adopted as a prototype.
  • All of the above-mentioned known guide devices of a rope tow are characterized by the fact that they are stationary frame structures, which are expensive to manufacture, bulky, difficult and sometimes impossible to install on the uneven terrain of a ski slope, and it is difficult to maintain the slope in the installation area (for example , compact using a snowcat), it is impossible to quickly adjust the feed height of the yoke bar at the output of the guide device, which is necessary when, for example, children use the lift.
  • the problem to be solved by the present invention is to create a guide device for a rope tow lift that is inexpensive to manufacture, mobile, easy to install and maintain, and easily adjustable to the height of users.
  • the guiding device of the rope tow includes a support post configured to be installed on a ski slope along the rope tow, a hinge made at the free end of the support post with the ability to rotate in a plane running along its axis, cantilever attached to the hinge a counterweight having an elongated shape in a direction substantially perpendicular to the axis of the support post, and two guides attached at one end to the counterweight.
  • the guides are attached to the counterweight at a distance that ensures free passage of the landing part of the yoke rod between them, and their free ends are oriented and extend in the opposite direction relative to the cantilever mounting of the counterweight so that between them and the free end of the support post free passage of the landing part of the yoke rod is ensured, wherein the free ends of the guides are made converging to each other.
  • a hinge made at the free end of the support post with the ability to rotate in a plane running along its axis provides the ability to quickly change the height of the yoke bar exit from the guide device, as well as the ability to rotate the guides to an essentially vertical position, which provides operational freedom for processing the slope with a snow groomer at the location where the device is installed.
  • the counterweight used in the design solves the problem of cantilever fastening of the guides to the hinge, and the indicated the mounting location and location relative to the support post ensures free passage of the landing part of the yoke rod to the outlet of the device.
