Definitions

  • the invention relates to a double towing bracket with a longitudinal spar and with two angular towing brackets intended for one user each, which are directed away from one another with the one bracket leg transversely to the towing direction and are attached to a longitudinal bar with the end of the other bracket leg.
  • a towing bracket device in which two drag plates are each connected to a cross bar via a chain link or shackle eyelet connection which can be moved on all sides.
  • this tow bar device has never been put into practice because it has some very important disadvantages: the chain link or shackle eyelet connection provided causes the two drag plates to swing around in an uncontrolled manner. A risk to operational safety that arises from this should therefore exist in particular when boarding the vehicle, but also when transporting an individual, since the loosely pivoting second drag plate on the one hand injures the lift user, and on the other hand can easily get caught on lift supports, oncoming drag plates or the like.
  • the object of this invention is now to provide a double towing bracket of the type mentioned, which largely reduces the risk of falling when towing a lift and at the same time ensures optimum operational safety.
  • transverse or vertical axis refer to the towing direction.
  • Preferred embodiments of the invention are the respective claims, the puncture of the invention and its advantages can be found in the following description of exemplary embodiments.

  • the front longitudinal spar 6 is fastened at one end to the traction cable via a cable holder 14 and a connecting element 13.
  • the second end of the front longitudinal spar 6 is guided into a protective receiving cap 10 and firmly connected to it by a blind rivet 16.
  • the protective receiving cap 10 and the adjoining protection 9 envelop the joint device, which is not visible here.
  • the lower part of the protection 9 is designed in the form of 2 bellows-shaped opening closures, from which the two longitudinal stiles 8 are led out.
  • the longitudinal struts 8, which are arranged such that they are parallel and at a distance from each other in the rest position, are connected at their free ends to an attached cross bar and preferably secured by a blind rivet 23.
  • the free ends of the cross rail strips are arranged away from one another transversely to the towing direction.
  • each of the two angular single brackets 8; 15 can be in a substantially laterally directed away from the axis of the front longitudinal spar 6 to a predetermined win swivel kel.
  • Fig. 2 shows a side view of the double tow bar according to the invention.
  • the longitudinal bar spar 8 led out at the base of the protection 9 is oriented in the rest position along an axis running through the front longitudinal bar 6.
  • the two dashed representations illustrate the principle of deflection in a substantially vertical direction for adapting the cross bar rail to different sizes of people to be towed: each of the two angular single brackets 8; 15 can be pivoted up to a predetermined angle in a direction of movement essentially perpendicular to the axis of the longitudinal spar 6.
  • FIG. 3 shows a section through a joint device in the rest position.
  • a connecting piece 5 is fastened via a roll pin 21.
  • the connecting piece 5 designed as a square tube, accommodates in its middle part a torsion bearing 1 with 2 axle bearings aligned one above the other and perpendicular to the axis of the front longitudinal strut 6.
  • An axle 2 is arranged in each of the two axle bearings of the torsion bearing 1, each of which projects on one side beyond the side cheeks of the connecting piece 5 and is countered on the opposite side by a retaining screw 4 with a washer 18.
  • a holding rod 3; 4 pivotally attached.
  • a compression spring 7 which acts on the one hand on the connecting piece 5 and on the other hand the short 4 and long part of the support rod 3 in such a way that in the rest position it is in a perpendicular position to the axis 2.
  • the longer part 3 of the handrails 3; 4 is via a pipe receptacle fitting 12 and a locking pin 20 connected to the longitudinal bar 8.
  • a stop 11 preferably made of rubber, is arranged and secured via a roll pin 22. The width of the stop 11 is selected so that when both end pieces of the longitudinal bar 8 are in contact, a parallel alignment of the longitudinal bars 8 automatically results.
  • the arrangement of the torsion bearing 1 described here in the axis of the front longitudinal strut 6 has the advantage that the entire joint device is given a favorable elongated shape.
  • the joint device is closed in the upper part facing the front longitudinal spar 6 by a protective receiving cap 10, preferably made of impact-resistant plastic, which is connected to the front longitudinal spar 6 in a non-slip and rotationally fixed manner by a blind rivet 16.
  • a protective receiving cap 10 preferably made of impact-resistant plastic, which is connected to the front longitudinal spar 6 in a non-slip and rotationally fixed manner by a blind rivet 16.
  • a groove is provided in which the adjoining protection 9 is attached in a non-slip manner.

  • the shorter part of the holding rod 3, 4 presses the part of the compression spring 7 which acts on it against the spring force 7 in a counteracting manner together.
  • the movement path of the two longitudinal struts 8 is limited in the lateral direction by the respective compression possibility of the compression spring 7.
  • the upper, short part 4 of the handrails 3; 4 is chamfered in a wedge shape on the inside in order to prevent tilting with the compression spring 7.
  • the elastic bellows of the protection 9 is stretched during the spreading process in its lower area located between the longitudinal struts 8 and compressed in its central part.
  • the previously mentioned spiral spring 7 fulfills an additional function:
  • the torsion properties of a spiral spring 7 are used for suspension about the transverse axis 2 instead of the previously described torsion bearing 1.
  • the spiral spring 7, which in turn is seated on the axis 2, is connected with the one free end to the holding rod 3; 4 and with the other free end to the connecting piece 5.
  • an offset axis arrangement 2 as described in FIGS. 3 and 5, has proven to be advantageous.
  • an axis arrangement is also possible in which both axes lie in a common longitudinal axis and are mounted separately from one another. It is also conceivable in this latter device, the two support rods 3; 4 to be connected to each other via a single spiral spring.
  • FIG. 7 explains the principle of deflection or spreading in the direction of movement which is essentially vertical to the longitudinal axis of the front longitudinal spar 6.
  • FIGS. A further variant of the articulated suspension about the transverse axis 2 is presented in FIGS.
  • the longitudinal struts 8 are deflected in a substantially vertical direction to the axis of the front
  • the connecting piece is advantageously designed as a molded part and, as shown in FIGS. 3 and 5, provides an arrangement of the transverse axes 2 one above the other.
  • this connecting piece 5 are diametrically offset, namely in the area of the respective fastening screws 18, a total of two recesses with partially annular grooves, in each of which two compression springs 27 are fitted.
  • Each of the two compression springs 27 is supported with one end on the groove end and the other end on a pressure pin 26 pointing from the axis 2 into the groove interior.
  • the double tow bar for ski lifts according to the invention works as follows:
  • the double towing bar can be used instead of all t-bar systems in which T-shaped short or long bars are used as usual. Special design changes to the lift system are not necessary here.
  • the towbar according to the invention is fed in from the rear in the usual manner.
  • Each of the two drag lift partners now grips the longitudinal bar 8 assigned to them and, by depressing or lifting, adjusts the optimum drag height of the cross bar rail for them. Uncertainties when driving off afterwards or when tilting in the icy tow track, which is difficult with balance speeds are connected by the separate and spaced arrangement of the two angular single brackets 8; 15 can be mastered.
  • each of the two people being towed has their own longitudinal bar 8 for holding and supporting, any driving uncertainties during towing remain without influence for the respective tow lift partner. Differences in the track height in the form of bumps are automatically compensated for by the infinitely variable adjustment of the towing height of the cross bar rails.
  • the stop 11 provided in the extension of the front longitudinal spar 6 below the joint device keeps the two longitudinal spars 8 at a distance at all times. As a result, touching or crossing the angular single bracket 8; 15 and related possible hand injuries excluded.
  • both t-bar partners can move out of the lane to the side and bypass the obstacle up to a distance determined by the length of the longitudinal bar 8 and the respective joint construction.
  • the double drag bar will turn due to the restoring force of the suspension elements 1; 7; 27 automatically return to the respective rest position. This is achieved through the proposed axle bearings around the transverse and vertical axes 2; 17, by, resilient elements 1; 7; 27 are acted upon and after one of the spring force 1; 7; 27 counteracting deflection automatically cause a reset.

Abstract

Double barre de remorquage pour remonte-pentes, équipée d'une tige longitudinale antérieure et de deux supports à angle, un pour chaque personne, chaque bras du support (15) étant disposé perpendiculairement à la direction de remorquage et étant tourné dans le sens opposé à l'autre, l'extrémité de la barre longitudinale du support étant fixée à la tige longitudinale antérieure (6) et étant rotative autour d'un axe transversal. Les deux supports individuels (8; 15) sont déplaçables, au moyen d'un dispositif d'articulation, autour de deux axes, notamment autour d'un axe transversal et en même temps autour d'un axe vertical, de manière à disposer de nombres infinis de possibilités d'écartement l'un de l'autre. La force nécessaire pour ramener les supports à leur position de repos est fournie par des unités de ressort qui agissent sur les articulations. Le dispositif d'articulation possède, en plus, une butée disposée entre les deux barres longitudinales de support (8), afin d'assurer leur séparation. La double barre de remorquage permet de réduire notablement le risque de chute pendant le remorquage et présente un niveau de fiabilité élevé lors du fonctionnement.
