The running gear of the cableway vehicle runs onto and attaches to the carrying vehicle, whereupon the cableway vehicle is movable along the adjoining track by the carrying vehicle.

Description:
BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The specific invention relates to a system for transporting people or goods having at least one transport cable to which a cable car vehicle which is constructed with a travel mechanism and a vehicle cabin can be coupled or having at least one carrier cable or at least one travel path on which at least one cable car vehicle which is constructed with a travel mechanism and a vehicle cabin can be moved by means of a traction cable to which the travel mechanism is coupled. 
     Cable car systems are known for transporting people. These are systems in which cable car vehicles, for example, gondolas, are moved along at least one carrier cable, wherein they are moved by means of a traction cable or in which the cable car vehicles are secured to a transport cable or can be coupled to a transport cable. 
     These are also systems having cable car vehicles which are moved along a fixed travel path, for example, along travel rails, by means of traction cables. 
     In all such cable car systems, there is the difficulty that the travel paths therefore have to be at least substantially linear, since the guiding of the traction cables around curves involves significant technical difficulties. 
     Cable car systems in which the cable car vehicles are moved along carrier cables or by means of transport cables are therefore advantageous since the carrier cables or the transport cables are guided by means of supports, whereby transport of people is enabled in a simple manner, even under difficult topographical conditions. 
     Systems for transporting people using cable car vehicles which are provided with a drive motor by means of which they can be moved along travel paths, in particular along travel rails, are therefore advantageous since the travel paths may be constructed with curves without technical difficulties being caused thereby during the movement of the cable car vehicles. 
     BRIEF SUMMARY OF THE INVENTION 
     An object of the specific invention is to provide a system for transporting people by means of which, on the one hand, the advantages of the known systems for transporting people are ensured and, on the other hand, the disadvantages thereof are avoided. 
     This is achieved according to the invention in that the at least one transport cable or the at least one carrier cable or the travel path is adjoined by at least one additional travel path, in particular at least one travel rail, along which at least one carrier vehicle which is constructed with a drive motor for the cable car vehicle can be moved, wherein the travel mechanism of the cable car vehicle can be advanced toward the carrier vehicle and can be secured thereto, whereby the cable car vehicle can be moved by means of the carrier vehicle along the at least one adjacent travel path. 
     Preferably, the at least one adjacent travel path for the carrier vehicle is formed by at least one travel rail or at least one travel beam. 
     Furthermore, the carrier vehicle can be constructed with at least two pairs of running rollers and where applicable with pairs of guiding rollers. 
     Preferably, the carrier vehicle is constructed with a carrier frame for the travel mechanism of the cable car vehicle, to which carrier frame the travel mechanism of the cable car vehicle can be locked. To this end, the carrier vehicle and the cable car vehicle can be constructed with at least one locking device for securing the travel mechanism of the cable car vehicle to the carrier vehicle. 
     Preferably, the locking device has two clamping jaws. In this instance, a fixed and a movable clamping jaw may be provided, wherein the movable clamping jaw can be moved by means of a clamping lever counter to the action of a restoring force, preferably of a pressure spring, from the closed position into the open position. In this instance, the clamping lever can be constructed with a control roller with which a control rail is associated in the transfer station. Furthermore, the travel mechanism of the cable car vehicle may be constructed with at least one locking pin which cooperates with the clamping jaws located on the carrier vehicle. 
     The carrier vehicle may be constructed with a combustion engine or with an electric motor, wherein the electric motor is supplied with electrical power by means of conductor rails which are arranged along the travel paths. In addition, the carrier vehicle may be able to be driven in an inductive manner.

     DESCRIPTION OF THE INVENTION 
     As can be seen from  FIG. 1  and  FIG. 1A , the illustrated portion of such a system for transporting people has an end station  1  and a transfer station  2 . Between the end station  1  and the transfer station  2  are two pairs of carrier cables  3 ,  3   a  which are carried by at least one support  4 . Cable car vehicles  5  which are coupled to traction cables  31  and which are constructed with cable car cabins can be moved along the carrier cables  3 ,  3   a.    
     At the transfer station  2 , the carrier cables  3 ,  3   a  are adjoined by travel paths  6 ,  6   a  which are located on supports  4   a  and along which carrier vehicles  7  which are constructed with drive motors for the cable car vehicles  5  can be moved. Since the carrier vehicles  7  are not moved by means of traction cables, but instead by means of the drive motors which are located thereon, the travel paths  6 ,  6   a  do not need to extend in a linear manner. Instead, the travel paths  6 ,  6   a  may be constructed with curves. 
     The travel paths  6 ,  6   a  may extend either as far as an additional transfer station, which pairs of carrier cables  3 ,  3   a  adjoin again, or as far as a second end station. In this instance, any number of such portions of pairs of carrier cables  3 ,  3   a  and travel paths  6 ,  6   a  may be provided. The carrier cables  3 ,  3   a  are provided in those portions in which the travel paths extend in a linear manner. However, as soon as bends are required, in particular as a result of the topographical conditions in the route guiding, portions having curved travel paths  6 ,  6   a  are provided. 
     The operation of such a system for transporting people is as follows: 
     In the end station  1 , the cabins of the cable car vehicles  5  located therein are entered or left by passengers. Subsequently, the cable car vehicles  5  are moved by means of the traction cable  31  along the carrier cables  3  to the transfer station  2 . In the transfer station  2 , the cable car vehicles  5  are transferred onto a carrier vehicle  7  at that location. Subsequently, this carrier vehicle  7  with the cable car vehicle  5  which is secured thereto is moved along the travel path  6  either to another transfer station or to a second end station. From the second end station, the cable car vehicles  5  are moved back along the travel path  6   a  and the carrier cables  3   a  to the first end station  1 . 
     As can be seen from  FIG. 2  and  FIG. 2A , guiding rails  21  which are associated with the respective pairs of the carrier cables  3 ,  3   a  and transport tires  22  which are associated therewith are located in the transfer station  2 . The cable car vehicles  5  are constructed with cable car cabins  50  and travel mechanisms  51 . By means of the transport tires  22 , the travel mechanisms  51  of the cable car vehicles  5 , after they have been uncoupled from the traction cable  31 , are moved further along the guiding rails  21 . The traction cable  31  is laid over three redirection discs  32  by means of which it is guided back parallel with the second carrier cable  3   a  of the pair of carrier cables  3 ,  3   a  to the first end station  1 . The pairs of carrier cables  3 ,  3   a  are adjoined by the travel paths  6 ,  6   a  which are each formed by pairs of travel rails  61 ,  61  a, along which the carrier vehicles  7  and the cable car vehicles  5  which are carried thereby can be moved. 
       FIG. 3  shows a transfer station  2  in which a carrier vehicle  7  is located. 
       FIG. 3A  shows the transfer station  2 , in which a cable car vehicle  5  having a cabin  50  is located, after it has been uncoupled from the traction cable  31 , wherein the travel mechanism  51  thereof is moved along one of the guiding rails  21  by means of the transport tires  22  to the carrier vehicle  7 . 
       FIG. 3B  shows the transfer station  2 , wherein the cable car vehicle  5  is located in the position after the travel mechanism  51  thereof has been approached toward the carrier vehicle  7 , wherein it is locked thereto. 
     Subsequently, the drive of the carrier vehicle  7  is switched on, whereby it is moved with the cable car vehicle  5  along the travel rails  61 , as illustrated in  FIG. 3C . 
     In  FIG. 4  and  FIG. 4A , a portion of this cable car system which is constructed with travel paths  6 ,  6   a  is illustrated as a front view. 
     The travel paths  6   a ,  6   a  are located on carrier beams  41  of supports  4   a.    
     Each of the travel paths  6 ,  6   a  has a pair of travel rails  61 ,  61   a  along which the carrier vehicles  7  can be moved. The travel mechanism  51  of a cable car vehicle  5  is located on the carrier vehicles  7 . There is articulated to the travel mechanism  51  a carrier bar  52  to which the cabin  50  is secured. The travel mechanisms  51  are constructed with four pairs of running wheels  53  which are supported on rockers  54 . 
     With reference to  FIG. 5  and  FIG. 5 a   , the travel mechanism  51  of the cable car vehicle  5  and the carrier vehicle  7  and the locking of the travel mechanism  51  to the carrier vehicle  7  are explained below. 
     There is articulated to the travel mechanism  51  the carrier bar  52 , to the lower end of which the cabin  50 —which is not illustrated in this drawing—is secured. The travel mechanism  51  is constructed with four pairs of running wheels  53 , by means of which the cable car vehicle  5  can be moved along the carrier cables  3 ,  3   a . The travel mechanism  51  is further constructed with clamping jaws  55  by means of which the travel mechanism  51  can be clamped to the traction cable  31  which is associated with the two pairs of carrier cables  3 ,  3   a . The two clamping jaws  55  are moved into their closed position by means of control rollers  56  which are under the action of pressure springs  57 , whereby the travel mechanism  51  can be coupled to the traction cable  31 . 
     The travel rails  61 ,  61   a  are secured by means of carrier sheets  62  which are spaced apart from each other to carrier pipes  63  which extend along the travel paths  6 ,  6   a . The carrier pipes  63  are secured to the carrier beam  41 . Each carrier vehicle  7  is constructed with a travel frame  71  on which there are supported a plurality of pairs of running rollers  72 , guiding rollers  73  which can be rotated about axes which are orientated at least substantially horizontally, and guiding rollers  74  which can be rotated about axes which are orientated at least vertically. 
     The running rollers  72  travel on the upper side of the travel rails  61 ,  61   a . The guiding rollers  73  and  74  travel on horizontal and vertical abutment faces of the travel rails  61 ,  61   a , whereby the carrier vehicle  7  is guided along the travel paths  6 ,  6   a . Each carrier vehicle  7  is constructed with a carrier frame  75 , on which the travel mechanism  51  of the cable car vehicle  5  is brought for support. The travel mechanism  51  is secured to the carrier vehicle  7  by means of two locking devices  8 . 
     As can be seen in particular in  FIG. 5A , the locking devices  8  comprise a fixed clamping jaw  81  and a movable clamping jaw  82  which are located on the carrier frame  75 , and a locking pin  83  which is secured to the travel frame  51  by means of a carrier sheet  87 . The movable clamping jaw  82  is located on a clamping lever  84  which can be moved by means of a control roller  85  which is guided along a control rail  80  counter to the action of a pressure spring  86  into the open position thereof and is retained therein. 
     As soon as the travel mechanism  51  on the carrier vehicle  7  has been moved into position so that the locking pin  83  is located between the two clamping jaws  81  and  82  which are located in the open position thereof, the movable clamping jaw  81 , as soon as the control roller  85  has left the control rail  80 , is moved by the pressure spring  86  into the closed position thereof, whereby the travel mechanism  51  is locked to the carrier vehicle  7 . 
     When a cable car vehicle  5  is moved into a transfer station  2 , the cable car vehicle  5  is uncoupled from the traction cable  31  and the travel mechanism  51  thereof is moved along the guiding rails  21  by means of the transport tires  22  to a carrier vehicle  7  which is located in the transfer station  2  and placed thereon. Subsequently, the cable car vehicle  5  is secured by means of the two locking devices  8  to the carrier vehicle  7 . Subsequently, the cable car vehicle  5  is moved by means of the carrier vehicle  7  along the pair of travel rails  61  to a second end station or to another transfer station. In the other transfer station, the cable car vehicle  5  is unlocked from the carrier vehicle  7 , further moved by means of the transport tires  22  along the guiding rails  21  to another pair of carrier cables  3 , coupled at that location to another traction cable  31  and moved along the carrier cables  3  to another station. 
     Along the travel rails  61  a and the carrier cables  3   a , the carrier vehicles  7  and the cable car vehicles  5  are moved back to the transfer station  2  and to the end station  1 . 
     The drive of the carrier vehicles  7  is carried out by means of combustion engines or by means of electric motors. To this end, there may be provided along the travel paths  6 ,  6   a  conductor rails by means of which the electric motors are supplied with electrical power. In addition, an inductive drive of the carrier vehicles  7  may be provided. 
     By means of such a combination of a system for transporting people formed by carrier cables  3 ,  3   a  and travel paths  6 ,  6   a , the travel paths may therefore be adapted to the specific topographical conditions since the travel paths  6 ,  6   a  do not have to extend in a linear manner, but instead can be constructed with curved regions.
