For greater strength, said sheet-metal parts have at least partly bevelled edges and form profiled shapes and rigid plates. Some of the profiled shapes constituting the walls form support frame elements (8), which together with horizontal floor supports (9), embody a rucksack frame. The support frame elements (4, 8, 9) are part of the elevator car and vice versa.

Description

ELEVATOR CABIN DESCRIPTION The present invention relates to a car or cabin for an elevator, which can be moved on vertical guide rails by a lifting device, with walls which are composed of metal sheet members and which, to increase the resistance , are bent at least partially over the edge and form profile sections, wherein the individual members of these profile members constituting walls extend beyond the profile of the cabinet at least downwardly so as to form frame members of the frame. support for the dressing room. German Utility Model No. 1 851 338 describes and shows a car frame construction of the kind mentioned above. In this solution, the individual wall part profile sections of the side walls have longer projections and in this form they are raised to what are called side panel profile sections surpassing the upper edge of the car and form, together with sections of similar elongated roof profiles, a superior carrier fork. A suspension clamp for transporting elements, which is formed from metal sheet profile sections, can be incorporated in this carrier fork.

This solution is confined to the solution of the upper carrier fork by means of metal sheet profile sections and side panel profile sections connected to each other, whereby a suspension point for a car is built. The construction of the whole car body is not evident from the same and therefore the way in which the rigidity of the total car seat with this suspension construction is also not known. An additional limitation in the use of this solution is that a suspension of the illustrated class should be placed as centrally as possible so as to avoid distortion of the car body. The present invention has as an objective the creation, by means of metal sheet plates and sections of metal sheet profile, of a car which can be guided and suspended eccentrically. This object is met by the invention characterized in clause 1 and illustrated by way of example in the description and drawings. The invention is distinguished in this way because the car wall members form a cantilever sling for the car guide on one side of the guide rails and base beams are connected to the support frame members that form or support the carcass. base of the dressing room. The support frame members are body parts of the car, and vice versa.

The exclusive use of metal sheet profile sections for this support frame cabinet corresponds to a unitary construction system. Advantages and advantageous improvements are specific in the dependent clauses. A high angular rigidity of the support members is obtained by penetration of the vertical and horizontal construction elements, together with additional screw connections. The positions specifically stressed in the guides and suppression devices have reinforcement elements. The guide shoes and the suppression devices can be mounted directly on the support frame members. A section of profile placed parallel between the base beams has, at one projection end, suspension points for the transport elements. A preferably hydraulic lifting device can be placed between the guide rails. Vertical support frame members and a wall element connect transversely to these forming a complete side wall of the car. The invention is explained in greater detail in the following, with reference to the examples of the embodiment and is illustrated in the drawings, in which: Figure 1 shows a dressing room according to a first embodiment with illustrated support and compartment elements separately and with a guide on one side, figure 2 shows all the parts of the car according to a second example of modality, with the guide on the rear side, figure 3 shows the car of the figure. 2, in an assembled state, and figure 4 shows, by way of example, the hydraulic cable impeller that moves the car, according to the invention. A car built as a compartment element is designated as number 1 in Figure 1.

A side wall, which is to the left when viewed from the front, of the lifting car 1 consists essentially of two vertical support frame members 8 in the form of metal sheet profile sections, which are transversely connected. by means of a first member 4 of a wide side wall and in this combination form the complete left side wall of the car 1. The two members 8 of vertical support frames each have in the lower part a respective conduit opening 22, through which horizontal base beams 9 are guided and are connected by means of screws to the floor surface of the profile section in FIG. U-shape which has extremities of different length, of the vertical support frame members 8. This clamping mode guarantees a high angular rigidity. The respective suppression device 21 is clamped with an activating lever 24, together with the base beam 9, to each vertical support frame member 8 and is supported by a reinforcing plate 14 for the purpose of reinforcing all the equipment. A respective lower guide shoe 15 is placed below each suppression device 21 at the lower end of the vertical support frame members 8. The upper guide shoe 15, reinforced by a guide shoe carrier clamp 23, is placed on the upper ends of the vertical support frame members 8. One end of a carrier fork with the suspension points 18 for the transport elements 17 projects below the first broad side wall member 4. This suspension arrangement is especially suitable for a classic hydraulic cable impeller (see Figure 4). The parts described and illustrated hitherto form, on the one hand, a complete cantilevered sling and, on the other hand, the entire left side wall of the car 1. The compartment elements additionally illustrated separately from the car 1 consist essentially of a car base 10.1, a rear wall member 2, a first narrow side wall member 5, a second side wall member 7 left, a broad indicator carrier 6 placed between the two narrow side wall members 5 and 7 and a roof 19 of dressing room. The base 10.1 of the dressing room has, on its three sides, edges bent upwards, towards which the wall members 2, 3, 4, 5, 6, 7 and 8 are fixed at their lower ends. It is evident from the foregoing that member 8 is both a wall member and a support frame member. The base 10 of the car has on the inlet side, a front surface 11 bent downwards, which is held by clamps 12 carriers which support a surface 13. The carrier clamps 12 are also provided for the reception of a profile section threshold, which is not illustrated. In addition, the carrier fork 16 is left under the base 10.1 of the car and is firmly connected to it. In addition, the base 10.1 of the car is located on the base beams 9, which are sized to accept the maximum transport load. A fixed connection is also provided with these. The base 10.1 of the dressing room is covered with a multi-layer interposed plate, which is not illustrated, during the manufacture of the dressing room. The members 2 to 8 of the car wall have a surface that is already ready for use, because for this purpose sheet metal plates are provided with a laminate, preferably what is called a "cover plate", which are used as initial material. They can be applied additionally, according to the needs, decorative wall coverings. The indicator board carrier 6 is a narrow wall member normal in its basic concept, but is additionally provided for the incorporation of call transmitters 26, a floor indicator 25 and a ventilation grill 27. The side edges 28 folded downwardly of the car roof 19 have fastening points 29 for screw connection to the side and rear wall members 2., 3, 4, 5, 6, 7 and 8. The fastening points 29 have spacers 30 for the purpose of creating a ventilation slot that runs all around. An additional connection profile section 20 on the supporting frame side of the car roof 19 serves for reinforcement of the upper car part. The guide planes between the guide rails 34 and the front entrance of the car 1 have a right angle with respect to each other. A lifting car 1, which is analogous in principle compared to that of Figure 1, is shown in Figure 2. The differences are the following: This car has a slightly lighter construction for a smaller transport load and dimensions that differ in correspondence. The guide planes between the guide rails 34 and the front entrance of the lifting car 1 are, according to figure 2, parallel to each other, and the frame supporting the car in this variant is formed by wall members of the back wall of the dressing room. In this way, a complete rear wall or a complete side wall of the car 1 is formed by the vertical support member 8 together with the wall member 2 to 4. The base part of the dressing room is constructed to be of multiple parts in this variant and consists of a base 10.2 of the car with edges bent over itself laterally downwards and an edge bent upwards rear. The upper sides of the base beams 6 here form the two edge portions of the car base 10.2 at the same level. The base beams 16 are accordingly connected here by their inner sides with the laterally bent side edges of the car base 10.2. The front side of the car base 10.2 is formed by a front profile section 33 screwed and the rear side of the car base 10.2 has an additional transverse beam 32. The car base 10.2 and the upper sides of the beams 16 are subsequently covered by a base covering or a base plate. The intermediate space between the wall members 4 and 7 or between the wall members 3 and 7 is provided for the wall member that is constructed as an indicator board carrier 6. The wall members 2 to 8 are interconnected by clips which engage around and hold together the folds of the wall members. The wall members 3 and 7 have ventilation openings 27.

Figure 3 shows the car according to Figure 2, in the assembled state. The indicator board carrier 6 and a door driver increase the body of this car to the completed car 1, ready for installation. Figure 4 shows, by way of example, a hydraulic cable impeller as would be used for the car 1, according to the invention. A hydraulic stroke cylinder 35 is placed within the guiding plane of the two guide rails 34 and is supported on a base 39 of an axis of a shaft 37. A coated deflection roller 36, around which the elements 17 of support, it is placed on the head of the rod. A translation ratio of t = 1: 2 is obtained by this. A transverse guide beam 38 prevents lateral deflection of the rod head with deflector roller 36. The parts of the two variants according to Figure 1 and 2 or 3, can be produced rationally in large quantities of parts. Only the indicator board carrier 6, the call transmitters 26 of which are provided in correspondence with the floor number present, counts as a dependent sub-assembly in order. The door impeller is a separate and complete and complete additional sub-assembly, together with the indicator board carrier 6, as already explained, the car body inside the individual and finished car body l.
