Definitions

  • the present invention relates to a fall protection device for armchairs of chairlifts according to the preamble of claim 1.
  • the footrests extend from a crossbar of a frame, the two arms of which are articulated on the flanks of the armchair itself. If the footrest is pivoted about its pivot points into a first position, namely into the open position, it rests on the upper crossbar of the frame supporting the armchair, while in the second position the crossbar of the footrest frame also has the task of locking off the passengers .
  • the object of the present invention is to remedy the disadvantages of the footrest currently used by avoiding the possibility of avoiding the obstruction during the rotation of the armchair.
  • the blocking of the locking bracket in its position, in which the seating space is limited can be automatically released in the station upon arrival, thus preventing an operator himself from intervening. This means that the operator can only focus on the safety of the passengers when the armchairs exit the station.
  • the same support axis of the locking bracket is also the support axis of a footrest.
  • the locking bracket according to the invention is formed by the bracket of a footrest.
  • the articulation of the locking bracket can itself be prestressed in the opening direction of the bracket. In this way, the bracket is pressed onto the hook in its closed position, so that any striking movements while the armchair is moving are avoided.
  • the linkage is provided with two stops which lock a nose of the link plate of the bracket arm.
  • the known locking systems on the armchairs of chairlifts also have the major disadvantage that they are not particularly safe for children or people of smaller stature: namely, because the distance between the locking bar, the backrest and the seat is too large, there is a risk that children in a moment of inattention, slide or get under the barrier bar and fall off the armchair.
  • the child lock device replaces a conventional footrest.
  • stirrup together with its safety system, is added to an armchair which is already provided with a conventional footrest.
  • an armchair frame 1 is provided with a suspension 2, which is clamped in a known manner via a clamp on a support rope, not shown.
  • the frame 1 has an upper belt 2, which is connected via two side posts 4 to a lower belt 5 carrying the chair 30.
  • a bracket 6 is attached to the post 4 and carries a support 7 firmly. This is with a support hole 8 parallel to the back of the chair 30 i.e. axis perpendicular to the direction of travel of the chair. In this bore 8, a support pin 9 is received, which is inserted into a corresponding bore of a link plate 10 of an arm 11 of a locking bracket 12.
  • the arm 11 is connected to the articulation disc 10 via a flange 13 such that the axis of the arm 11 is spaced from the plane of the disc 10.
  • a biasing spring is arranged between the carrier 7 and the disc 10 in a known and therefore not shown manner, which the bracket 12 clockwise 31 attempts to pivot or lift.
  • a pin 14 extends radially from the articulation disk 10 and is essentially parallel to the arm 11 or in any case projects from the direction facing away from the disk toward the arm 11 to the crossbar of the bracket 12.
  • a hook 16 is articulated on an essentially perpendicular plane 15 of the carrier 7 parallel to the axis of the bore 8 by means of a link 17. So the hook 16 can be pivoted in the plane 15. This pivoting can be actuated by a handle 18 which is connected via a rod 19 to the hook 16 in a plane parallel to the plane 15. Therefore, if the hook 16 is pivoted, it can block the movement of the bolt 14 and the pivoting in the clockwise direction 31 is interrupted.
  • the locked position of the hook 16 when pivoting the bolt 14 is that in which the crossbar of the bracket 12 is located above the seat plane of the armchair 30 and at a distance from the armrest backrest.
  • the rod 19 is connected via a Bowden cable 22 to an articulation point 23 of an arm 24 of a toggle lever 25 articulated on a flange 26.
  • the toggle lever 25 is provided with a slide roller 27 which interacts with guides, not shown, which are provided on a support or in the chair lift stations.
  • the closed position is shown in broken lines in FIG. 1, while the open position of the safety bracket 12 is shown with the solid line.
  • the opening mechanism of the protective device shown in Figure 1 has the lever actuation in the area of the frame, this can also be at any other suitable location, e.g. near the bracket clamp.
  • the edged footrest may be articulated on the same axis on which the locking bracket 12 is articulated.
  • a footrest of a known type could itself be provided with a device for blocking the opening movement, so that the crossbar, from which the actual footrests extend, acts as a locking crossbar.
  • an armchair 101 in a known and therefore not further described manner has a suspension 102, which can be connected to a suspension cable, not shown, and a frame 103 with a locking bracket 104 of a footrest 105.
  • the footrest 105 is connected to an articulation 107 via arms 106.
  • One of the arms 106 is provided in the region of its free end with a bolt 108 which interacts with a hook 109.
  • the latter can be actuated by means of a handle 110 in order to pivot an articulation 111 with a pivoting limitation fixed by a stop 112 fastened to the frame, the stop on the one hand against a flank 113 of the hook 109, in which the bolt 108 of the bracket 104 in Hook is locked, and on the other hand strikes against a flank 114, in which the bolt 108 is freed from the hook.
  • a handle 110 in order to pivot an articulation 111 with a pivoting limitation fixed by a stop 112 fastened to the frame, the stop on the one hand against a flank 113 of the hook 109, in which the bolt 108 of the bracket 104 in Hook is locked, and on the other hand strikes against a flank 114, in which the bolt 108 is freed from the hook.
  • the handle 110 is expediently pivotably attached to a tab 116 of the hook 109 about an articulation 117 on the frame 103.
  • a Bowden cable 118 is articulated to the tab 116 in 117, which is articulated at the other end to a lever mechanism 120, which in turn is pivotally attached in 121 to a flange 119 which is fastened to the upper end of the suspension 102.
  • the lever mechanism 120 has an actuating lever 122 which can be actuated by a positive guide 123 present in the stations of the chair lift.
  • the guide 123 is expediently loaded by a spring 124 in a known manner.
  • the arms 106 expediently extend in the closed position shown in FIG. 4 in an inclined position above the armchair 101, in order to be connected to one another by a crossbeam 125 which extends from the Seat 126 and from the backrest 127 is spaced such that the highest possible possibility is avoided that a child can slip under the bars 125 and also the possibility is taken to rise on the seat level by the bar 125 itself is firmly locked in position in the hook 109.
