The invention relates to a towing device for passenger transport, in particular a ski lift, consisting from a cable winch built on a sled, a transmission gear connected to the same and a drive machine that can be coupled to the latter, preferably an internal combustion engine, the free end of the pull rope wound on the winch for attachment to a Fixed point is set up and the carriage od a handle bar. The like. Has. ίο

Such traction devices are known. In pulling devices of this type, the arrangement has so far usually been this way taken that the handlebar is rigidly connected to the slide. However, this is disadvantageous because the Persons hanging on the handlebar during transport are required to make all movements of the Traction device to follow exactly.

It is the object of the present invention to eliminate this disadvantage of the known pulling devices, i. H. to improve the handling of such a device.

According to the invention, this object is achieved in that the handle bar on all sides of the slide is pivotably mounted.

In this way, people hanging on the handlebar during transport are not forced to to cover their way only in full compliance with the traction device, but can in the If necessary, make relative movements to the sled or pulling device while driving. at Using the pulling device as a ski lift, this has the advantage that the skier can also drive upwards can perform sporting exercises that only deviate from the path of the traction device Railway are possible, such. B. stem arch, swings or the like.

According to a further feature of the invention, the arrangement is made such that the handle bar in a manner known per se the one or more for switching the cable winch drive on and off for the Speed control od. The like. Required operating lever carries. This arrangement gives the further Advantage that the people transported regulate the train speed themselves and in this way the The best way to adapt the journey to the road conditions.

In the following description, an embodiment of the invention is based on a drawing explained in more detail.

An internal combustion engine 2 of a known type is attached to a base designed as a slide 1. Furthermore, the pedestal carries a horizontally mounted towing device for passenger transport

Cable drum 3, which is firmly connected to a V-belt pulley 3 α of a transmission gear 3 α to 5a. Via adjustable intermediate discs 4 of the transmission 3 to a Sa the rope drum 3 is connected to a further pulley Sa, which is seated on a drive shaft. 5 The same can be coupled to the output shaft of the internal combustion engine 2, also not shown, via a releasable coupling (not shown).

On the pedestal, a handle bar 6 is mounted pivotably on all sides at 1 a. The handle bar 6 is flexible Associated tube 7, within which two control cables run. Two invisible ones Control handles on or near the handle bar 6 are via the mentioned cables of the throttle the internal combustion engine 2 and the clutch for the drive shaft 5 are operated.

On the cable drum 3 one end of a pull cable 8 is attached, the other end by means of a Armature 9 is held stationary. A ratchet pawl, not shown, is mounted inside the cable drum, which cooperates in a known manner with a ratchet wheel fastened inside the cable drum and prevents the cable drum from running back. A manual shift lever 10 is on one inside the drum axis mounted shaft 10 α and is used to switch off the ratchet pawl and thus to Release of the cable drum to return. On the drum axis is also inside the cable drum 3 still arranged a centrifugal governor, which a friction brake of a known type for the cable drum when a certain speed is reached.

The pedestal is equipped with snow runners 11 and provided with a cover 12, indicated by dotted lines, which covers the elements attached to the pedestal to the outside. The operating handles of the device protrude through openings 12 a, 12 b, 12 c of the cover.

With regard to the operational safety of passenger transport, the device is still equipped with a backflow protection equipped. This backflow protection can, for example, consist of a Drag flap, not shown, which at the rear end of the snow runners 11 is pivoted and the device in a known manner against reverse flow in the event of malfunctions, eg. B. Broken rope, secures. This drag flap is put together, for example, before the device goes downhill with the handle 6 folded up.

The handling of the traction device is as follows: The pedestal is set with its snow runners 11 on the traction route, the tow flap is lowered and the anchor 9 is attached to the summit of the traction route with the unwinding of the traction cable 8, e.g. B. rammed into the ground or latched to a tree. The internal combustion engine 2 is then put into operation and the clutch handle on the handle bar 6 is actuated by one of the persons to be transported. This activates the drive clutch and the cable drum 3 is driven by the internal combustion engine 2 via the transmission 3 a to 5 a. The pull rope 8 is wound up so that the pedestal together with the people hanging on the handle bar 6 runs up the ski slope. The running speed can be regulated by the operator using the throttle lever on the handlebar 6 while driving.

When you arrive at the desired exit point, the drive coupling is released so that the ski lift stops. One of the descended skiers lifts the tow flap up to a locking position and then switches the manual lever 10 so that the backstop for the cable drum 3 is switched off. The pedestal now runs empty and driven by its own weight with the unwinding of the pull rope 8 down the slope again. The internal combustion engine 2 can easily remain in motion here, since the drive clutch is released, so that only the cable drum 3 with the gear 3 α to 5 a rotates idly during the downhill movement. The brake mentioned above keeps the return speed approximately constant.

One of the skiers who have meanwhile gone down catches the returning ski lift from below, lowers the drag flap and turns the manual lever 10, whereupon a new ascent can begin again.
Instead of an internal combustion engine, a

ίο Accumulator-driven electric motor for the drive the rope drum. The traction device can also be used for water skiing.
