Description

TOWNHOUSE ELEVATOR Description The invention relates to an attached lift, for the transport of people and goods, attached to a wall of a building that has box doors, with a cabin that runs through two guides in the manner of columns, in particular a self-propelled cabin attached to a counterweight by supporting members, the access from the cabin to the building being arranged and vice versa in the area between the guides, which are configured as load-bearing elements.

The elevator installations of the described technique are preferably mounted on the facades of buildings, in particular with a view to the modernization of existing buildings without a lift. For this purpose, the outer wall for the assembly of the elevator is provided with box doors. In front of the outer wall thus prepared an elevator shaft is built which joins said outer wall. In this hollow or box the assembly of the elevator is carried out with guide rails of the cabin and the counterweight, dampers, information elements of the box, etc., in the same way that the assembly is carried out in a box inside the building.

In the publication of the German application DE 1 506 479, a guided elevator is described and supported by two strong columns, through which counterweights run, without exerting any load on the building. A "double spring drive" engaging with pinions located on both sides is disposed on the cab, in each case on a roller chain that is recessed in a resilient manner in the columns. With this special type of drive it should be possible to dispense with a parachute device. However, what prevents the use of this type of construction as a comfortable elevator for people, is that the drive produces strong vibrations and noise and therefore is only suitable for small speeds, which also confirms the indication "for industrial lifts and of garages ". Furthermore, the document and the drawings do not show how the cabin is supported or how the access to the building is arranged and vice versa.

The object of the present invention is therefore to create an attached lift constructed in modular form and that can be prefabricated economically, is fully equipped, can be assembled in a short time, be used for the mid-range in regard to speed and height of elevation, and that meets the safety requirements of a lift for people.

This problem is solved by the invention characterized in claim 1 and presented in the attached drawings and the description.

The invention is distinguished, among other things, because the attached lift comprises very few parts and because, for small and medium lifting heights, it can be transported to the work site as a prefabricated assembly.

Advantageous refinements and improvements of the invention are indicated in the dependent claims.

Due to the adequate arrangement of the cabin, support frame and guides, the available surface is optimally utilized.

In the following the invention is explained in more detail, based on an exemplary embodiment shown in the three attached figures. These show: - Figure 1. An overview of the exterior face of the elevator.

- Figure 2. An overview of the interior side of the building.

- Figure 3. A top view of the attached lift.

Figure 1 shows the assembly view of an elevator attached to the outer wall 2 of a building 1. On the two lateral ends of a base module 12, which rests on a construction base 4, are supported and fixed frontally, to a track gauge distance, two vertical guide modules 10. At the upper front end of the guide modules 10, these are closed with a box head module 13 which saves the track width. 5 is arranged within the guide modules 10whose own drive located in its lower part drives on both sides a drive wheel 7, which rolls on the running surface of the guide module 10 and acts together with a support wheel 8 located on the opposite running surface of said module. guide 10. On the upper part of the car 5 guide rollers 9 are arranged which, rolling on three running surfaces of each guide module 10, guide the car 5 on the two horizontal axes. The car 5 is fastened in a support frame 6 that surrounds it, and is joined at the top, on both sides, by means of support members 19 passing through inversion pulleys 14 located on both sides of the box head module 13, in each case. in the case of a counterweight 18 (FIG. 2) running inside the guide modules 10. On the left side of the box head module 13 is arranged a speed limiter 15, actuated by a limiting cable 20 fixed to the cab 5 and guided by a lower reversing pulley 17 fixed on the left side of the base module 12. In the event of an inadmissible excess speed, a parachute device, not shown, located in the car 5 is triggered in a known manner. The guide modules 10 are connected to the building 1 on each floor 3, by means of a fixing module 11, consisting of a U-shaped frame fixed to the outer wall 2.

Figure 2 shows a front view of the attached elevator. The building 1, represented in section, has in the floors 3 door openings 27 with threshold recesses 28. The left guide module 10, partially cut, shows details of the counterweight 18. In a cage of vertical bars are arranged, one envelope another, disc weights whose total weight together with the bar cage is, for example, half the weight of the cabin with 1/4 payload. The guide modules 10 essentially have a partially structured and approximately square cross section. The elements of the box information, not shown in this figure, on the side of the box are preferably installed on the horizontal protruding arms of the fixing modules 11, and on the car 5 analogously opposite.

In figure 3 can be seen, in top view and partially in section, parts and subgroups of the attached lift. The vertical side parts of the support frame 6 are joined above the car 5 to a yoke 23, which supports on each of its sides a base plate 24 which is approximately L-shaped and is attached to the yoke 23 in adjustment by strength and form. On the base plates 24 the guide rollers 9, not shown here, are fixed. On the base plates 24 there are also, next to the yoke 23, the suspension points for the support members 19. The building 1 is closed on each floor 3 with a box door 22 and the cabin 5 is closed with a door of cabin 21. The distance between the inner faces of the guide modules 10 is indicated by "d", and a horizontal axis of parallel guide to the building 1, with 25. The constructive plane 26 of the support frame 6, maintains a distance "a" constant to the horizontal guide axis 25 and to the opposed vertical running surfaces of the guide modules 10. The width of the support frame 6 parallel to the horizontal guide axis 25 is greater than the distance "d" between the inner faces of the guide modules 10. With 29 are designated elements of the box information, arranged in the horizontal crosspieces of the fixing modules 11. The box information on the side of the cabin is indicated with 30 and arranged to a small distance in front of the box information 29, preferably on the roof of the cabin.

The support frame 6 arranged in front of the guide modules 10, seen from the building 1, reduces the constructive width of the entire attached elevator and with it the area of the construction base 4 required. The drive and control control, not shown, is arranged inside the cab 5 and next to it, especially inside the support frame 6 or adjacent to it, so that no additional installation space is required in the building 1. of machinery and control. For the door openings 27 that must be made in the outer wall 2 of the building 1, for example, the window openings existing in the landings or intermediate floors of a staircase can serve. By means of the corresponding adaptation works it is possible to install box doors 22, with an external wall, at justifiable costs, especially since these are the only constructive adaptations that are a precondition for the assembly of an elevator. During the opening of the box doors 22 on the outer wall 2 of the building 1, the fixing modules 11 are also installed simultaneously. At that moment, the building is already fully prepared for the assembly of the elevator. For medium lift heights or up to a permissible height or length for road transport, the lift is transported fully manufactured, pre-assembled and wired, to the building intended for assembly, where it is positioned and attached to the exterior wall of the building by means of the fastening modules 11. The transport of the finished elevator is possible because the guide modules 10, joined together with a base module 12 and a box head module 13, they constitute a rigid and self-supporting unit that can be transported even together with the installed cabin 5. The attached lift can be equipped after installation with a protection device of any type, for example made of glass, lattice or non-transparent solid elements, so that a box is formed where necessary to protect the technical devices against climatic influences. By means of a suitable architectural configuration of the protection device, the character of the building can be taken into account, in such a way that the attached elevator does not negatively influence the appearance of the building, but even involves new architectural accents.

The cabin 5 is equipped, as a prefabricated building group, with all the technical devices, and also contains, in addition to the complete drive, its control and command system. Also present are command control for call processing, call transmitters, door control, as well as lighting and communication media. For the equipment of the floors, prefabricated installation units containing the so-called floor transmitters and indicating elements are provided. The electrical installation of the box is preferably conducted as a prefabricated service channel through the fixing modules 11 and fixed thereto. For the supply of energy and the exchange of data there are provided, for example, contact lines and electro-optical systems, if the use of a hanging cable is not possible or is not desired.

However, the invention can also be applied in cabins without their own drive. In this case, the cab can be moved by a cable, which is led to the box head module 13, and a drive motor installed therein.

The aforementioned box information 29, or its supports, can also be fixed directly to a guide module 10, independently of the fixing module 11. As a further variant or complement, the installation of a code-encoded band is also proposed guide 10 for optoelectronic scanning.

In an improved embodiment, the fastening modules 11 are manufactured so that they can extend horizontally telescopically. In this way, it is possible to join the pre-assembled box doors 22 with the fixing modules 11 and, thanks to the telescopic extension capacity of the latter, transport them to the construction site with the removal of the guide modules 10.

As a parachute device, a normal wedge or roller parachute device is used, which acts on the guide module 10 at a specially configured point.

On the base module 12 there are corresponding damping devices for the cabin and the counterweights 18, which move in the guide modules . Said devices, not represented, are adequate to the needs of the service.

The adaptation to an existing building 1 is not limited only to the protection device. By means of color, decoration and construction variants, especially in the cabin 1, attractive additional effects can be achieved.

The attached elevator according to the invention can also be installed on any suitable wall for this or in the open center of a conventional staircase.
