Definitions

• the present invention relates to a cable elevator, which has a car and a counterweight, which, hanging on suspension cables, move in opposite directions along guide rails in an elevator shaft, the car guide plane formed from two car guide rails running parallel to the car front and approximately through the center of gravity of the car, wherein the elevator is driven by a drive unit with a traction sheave, which is placed in the shaft head area above the travel path of the counterweight so that the upper part of the cabin can reach a position in the shaft that is superior to this drive unit, and the support cables are located from a fixed point in the shaft head in the area of the counterweight side wall down and around one or two idlers of the counterweight, then up and around the traction sheave of the drive unit, then down and horizontally / diagonally under two idlers below the cabin run through and finally up again to a second fixed point on the cabin side wall.
• the present invention has for its object to provide a solution with which the advantageous arrangement of the drive unit can be realized while avoiding the disadvantages mentioned.
• the center of gravity of the balance weight arranged under the center of the balance weight support roller (s) comes closer to the shaft wall, than is possible with a traction sheave and idler roller arrangement parallel to the counterweight due to the distance between the traction sheave and the shaft wall given by the dimensions of the drive unit.
• the space-saving arrangement of the counterweight achieved thereby allows the use of a cabin with the greatest possible width.
• a further preferred embodiment of the invention is achieved in that the support cable section running vertically from the traction sheave to the first cabin support roller in the free shaft area between the shaft wall and cabin side wall is arranged, which is not claimed by the path of the counterweight with the surrounding guide rail retaining brackets.
• the preferred suspension cable arrangement proposed hereby does not cause any loss of installation space for the cabin. This is particularly advantageous if, in the case of large building heights, considerable vibrations of the suspension cable section mentioned are to be expected and therefore relatively large free spaces are required around it.
• the advantageous refinements of the invention also include that the first fixed rope point of the supporting ropes is provided on the supporting structure of the drive unit. This saves time and costs for attaching a fixed point support to the shaft wall during installation of the system and avoids a possible source of errors.
• the drive unit is designed as a worm gear, the drive motor being arranged vertically in order to reduce the space requirement.
• Another preferred embodiment includes that the counterweight is arranged laterally next to the cabin and its guide plane formed from two counterweight guide rails is arranged parallel to the cabin side wall.
• optimal use of the shaft space is achieved because a free space to the side of the cabin is required for the open access doors.
• the drive unit can be made observable and accessible by means of viewing windows and / or auxiliary doors in the usually freely available shaft front.
• An embodiment of the invention is shown in FIGS. 1 to 4 and explained in more detail in the following description.
• FIG. 1 shows a side view of the cable elevator installed in an elevator.
• FIG. 2 shows a section through the cable elevator installed in the shaft parallel to the front of the elevator car.

• an elevator cabin With 5 is a side view of an elevator cabin, the upper part of which is shown as cut away for better visibility of the drive arrangement behind it and which has a cabin door 6, shown schematically here.
• a counterweight 7 with an associated counterweight support roller 8 and two counterweight guide rails 9 can be seen.
• the counterweight guide rails 9 and the counterweight-side cabin guide rail 10 are fixed to the counterweight-side shaft side wall with a large number of guide rail retaining brackets 11 distributed over the entire shaft height.
• a drive unit 12 with a traction sheave 13 and an electric motor 14 is shown, which is mounted on a supporting structure 15, which consists of a profile frame 15.1 and a mounting plate 15.2 and in turn on two counterweight guide rails 9 and the counterweight side Cabin guide rail 10 is attached.
• the course of the supporting ropes 16 is also visible here, only one of a plurality of ropes arranged in parallel being shown in each case.
• the starting point is a first fixed rope point 17, which is integrated into the support structure 15 of the drive unit 12 in the area of the counterweight shaft side wall.
• the support cables first run downwards and then around the counterweight support roller 8, upwards and around the traction sheave 12 of the drive unit 11 down again and horizontally / diagonally under two cabin support rollers 18 below the cabin 5 and finally up again to a second fixed rope point 19 on the cabin side wall 20 (19, 20 not visible in this view).
• the mounting plate 15.1 of the support structure 15 has a cutout 21 so that this support cable section can be installed at a sufficient distance from the cabin side wall without the distance between the cabin and the counterweight installation needs to be enlarged.
• FIG. 2 shows a vertical section through the elevator shaft 1 and the elevator car 5, viewed from the access side, the sectional plane being between the car door and the car front.
• FIG. 3 shows a horizontal section through the elevator car 5 and the counterweight arrangement.
• the drive unit with its supporting structure lie above this section and are not visible.
• the cabin access is shown schematically here with an access shaft opening 3, a landing shaft door 4 and a cabin door 6. Also visible are the balance weight 7 and the associated balance weight support roller 8.
• the balance weight one can see one of the above the shaft height Distributed, screwed to the shaft wall guide rail bracket 11, with which the two counterweight guide rails 9 and the counterweight-side cabin guide rail 10 are fixed. On these three guide rails extending to the bottom of the shaft is in
• the supporting structure for the drive unit is attached (not visible here).
• the right-hand cabin guide rail 22 fixed to the cabin-side shaft side wall 20 is still visible.
• Fig. 4 shows a plan view of the elevator shaft 1 (without the shaft ceiling).
• the support structure 15 for the drive unit 12 which is fastened in the shaft head area to two balance weight guide rails and the balance weight-side cabin guide rail 10.
• the latter is arranged with its traction sheave 13 at an angle to the shaft wall in such a way that, together with an inclined position of the balance weight Support roller 8 results in a position of the balance weight 8 hanging with its center of gravity below the center of this balance weight support roller, which is closer to the shaft wall than is the case with shaft wall.
• parallel alignment of the traction sheave and balance weight support roller would be possible due to the dimensions of the drive unit 12.
• This illustration also shows that the support cable section running vertically from the traction sheave 13 to the first cabin support roller 18 is arranged between the shaft wall and the cabin side wall in the shaft area which is not occupied by the travel path of the counterweight with the guide rail holding brackets surrounding it, which makes optimum use of the shaft space by maximum cabin width allows.
• the drive unit shown here in the form of a worm gear shows clearly that the vertical arrangement of the electric motor 14 also brings considerable advantages with regard to the use of space mentioned.
• This arrangement also clearly shows the arrangement of the cage support rollers 18 attached below the elevator car, the two fixed cable points 17 and 19 and the supporting cables 16.
• These supporting cables extend from the first fixed cable point 17 attached to the supporting structure 15 to the counterweight supporting roller underneath and 180 ° around it, then to the overhead traction sheave 13 and 180 ° around it, then downwards and then horizontally / diagonally under two cabin support rollers 18 below the cabin 5 and finally up again to a second fixed rope point 19 on the Cabin-side manhole side wall 20.
