Abstract

The lift has two frames (2a, 2b) rigidly connected to one another by bridges to result in a unified, fixed carrying structure in the shape of a twin frame. The frames are located symmetrically to a side of guide rails, and are arranged at a distance from one another in such a manner that a space remains between the frames for accommodating a lift element. Each of the frames is an integral component of two side walls and a ceiling of a lift car, and rests with entire surfaces from outside against the side walls and the ceiling of the car.

Description

Self-supporting mobile cabin.

The invention is about an elevator with a cabin self-supporting mobile according to the generic term of the claim one.

The mobile elevator cabins are built until today without exception in such a way that a solid mobile cabin frame, on which a platform is placed or a closed elevator mobile cabin. The platform or the cabin elevator mobile house payload and / or people to transport. In the case of elevators suspended by the center, the platform, or the mobile elevator car, hangs in the direction wider in a "ring" that leads externally around of the platform, or of the mobile elevator car, all forces to and from the suspension medium and that in this way It requires its own construction space.

Punctually, however, I also know proposed in the state of the art, mobile cabins self-supporting diverging from the principle described above.

Thus, the published German patent application 30 32 240 proposes a self-supporting mobile cabin that must be manufactured as a construction of rigid sheet itself, double wall. In this In this case, at least one of the plates is deeply embedded in such mode, which presents convexities, to which the other can be welded sheet, so that the two sheets are kept at a distance one of another as a kind of "rigid flex sandwich". A similar construction is extremely complicated and requires a considerable effort in regards to machines for the deep inlay and an equally great effort when welding. Further, a similar double wall mobile cabin is an excellent body of resonance, which can only be damped in a difficult way such that a ride comfort is achieved that is at least moderately acceptable.

Another alternative is described by the patent British published 496 286.

This patent proposes to use for the cabin self-supporting mobile two grill constructions themselves rigid to bending, which are sized for the entire cabin load mobile, including the weight of the mobile cabin, of which one way the movable cabin roof and the other the cab floor mobile. By means of sheet metal panels that act as cords subjected to traction and forming the side walls and the wall later, those two grills are joined together - without use of an additional bearing structure along the walls side or rear wall. This construction is not without problems in different respects. On the one hand, it is not easy make a mobile cabin built in such a way really torsionally rigid, particularly with size, or surface basic, growing. Because the larger the surface of base, the greater the danger that the mobile cabin is requested by payloads, which are significantly outside of its zone of center of gravity, which then tend to twist the mobile cabin -particularly if they are also added tolerances by guide rails. Another problem is the union between the two grills and the sheet metal panels that form the side walls and the back wall. Here it should be used in all the joints, which correspond to the side of the floor and next to the ceiling, of the panels a correspondingly fixed joint, of size bigger and with it more expensive, to be able to guarantee Fatigue resistance of the mobile cabin. Finally it is not all simple to prevent resonance in a mobile cabin of this type, whose side walls and whose back wall is they consist exclusively of thin sheet metal panels but carriers

A construction that at the beginning goes in similar direction, is proposed by the international presentation of patent application WO 03/066499.

Also within the framework of that presentation used for the mobile cabin roof and the mobile cabin floor rigid constructions themselves, which are joined together by means of single wall sheet panels that act as cords subjected to traction. Unlike the construction proposed by British patent, not all panels that form the walls Side and rear wall adopt a bearing function, but only sheet metal panels chosen - preferably two sheet metal panels which in each case run in the center of the two side walls in vertical direction from top to bottom.

This construction considerably decreases the fixing effort that is necessary to join the panels sheet with the self-supporting constructions itself of the cabin floor mobile and mobile cabin roof, but leaves all solutions without solution other problems that arise in this type of construction. Particularly also right in this construction is difficult master the problem of torsion in the case of a solicitation considerably eccentric of the mobile cabin. Because the panels sheet metal carriers are also designed here essentially as cords subjected to traction and it is difficult for them to transmit, or well absorb torsion free, bending moments of greater magnitude, as they occur in the case of solicitation considerably eccentric of the mobile cabin floor.

Another alternative is known from DE 201 04 416. The construction proposed here uses a reinforced floor that it does not have any lower stringer, therefore it does not use a single bearing structure in the manner of a ring independent and much less one that is composed in each case of two closed frames around the mobile cabin. Rather it is provided here a grill type floor that is reinforced by of several sleepers. In addition, the bearing structure exceeds in this construction in the mobile cabin roof area extensively to the latter. This requires some construction space. The sides in this mobile cabin are provided with a reinforcing plate which laterally forms a unit with angular profiles thus represents a reinforcing element, which in short is formed as a U profile, which is located in the center of the plane that the guide rails extend to each other.

In light of all this, the invention has the aim of creating a rigid torsional mobile cabin that not only optimally use the hollow section, but at the same time also achieves a decrease in the construction space of The hollow head.

This goal is achieved with all of the characteristics of claim 1. Particularly achieves, because the supporting structure in each case is composed of two closed frames around the mobile cabin, which in each case are made in the manner of an independent ring and constructed of independent hollow profiles. In this case, the frames, which in each case are closed around the cabin mobile, they are connected to each other by bridges forming a frame rigid twin. In addition to this, the hollow profiles that form the framework are spatially arranged in a certain way, namely on both sides of the guide rails and not in an alignment with the guide rails (that is not so, that cut the plane that extend the guide rails to each other); with it the profiles gaps that form the frame use the construction space that in itself it is available laterally next to the rails of guide.

Because the supporting structure for transmit the forces due to the mass of the mobile cabin, including the payload, to the suspension medium, is composed (low the point of view of the non-positive union) of a closed frame around the mobile cabin, there is no need to use for the mobile cabin floor and mobile cabin roof, grills self-supporting or otherwise self-supporting elements themselves, which are designed to be able to sustain the load in a lasting way complete mobile cabin, including the cabin's own weight mobile. This reduces the manufacturing cost. At the same time it reduces the danger that the mobile cabin will twist. It is due that the mobile cabin floor can be solidly supported in the zone of its center of gravity and therefore should only be handled in the mobile cabin floor area bending moments substantially smaller.

Otherwise, the hollow profiles essentially independent that according to the invention should be used for frames they are substantially more resistant to torsions than flat cords, essentially smooth, subjected to traction, given that the four (or well several) walls of an independent hollow profile can lean against each other.

To this is added that the supporting structure closed around the mobile cabin not only consists of a single frame, but of two individual frames, which are preferably spaced 100 to 350 mm from each other, which not only form a bearing structure that is fixed, but also also supports relatively broad form, which usually runs in symmetrical on both sides of the guide rails and that is why in Innate form relatively little susceptible to torsions.

In this case, a couple of frames, which is also constructed of flat channels in special arrangement, it represents a very good compromise between high resistance and a requirement of space that is only minimal. Because the hollow profiles that form the frame is not precisely in a row with the rails guide, but use the construction space by itself no otherwise usable, which in itself is available laterally next to the guide rails.

Finally, to the construction according to the invention, also reduced construction heights are sufficient in the area of the head of the hole and, if necessary, also that of the bottom of the hole - the latter, namely when the structure bearing is also integrated in the mobile cabin floor.

In addition, the hollow profiles used for frames have a significantly more resonance tendency reduced and also substantially reduce the resonance of single layer sheet walls, in which they are integrated. It is due to the fact that the sheet walls are fixedly supported by the frames; the respective sheet wall is further subdivided into several smaller fields The smaller fields have in themselves a reduced tendency to resonance.

The expected characteristics of the claim 3 describe a particularly favorable type for join the hollow profiles with each other, which form frames 2 a and 2 b, safely and easily. In this case it is particularly favorable, under manufacturing views, introduce in each case the horizontal support and the vertical support one in another of such so that the angle seam proposed by the claim 4.

If in each case one of the bridges is welded, which are intended for the union of the two frames, at the height of the windows provided on the vertical supports as planned claim 5, then the bridge compensates for the weakening who first experiences vertical support due to the window.

The mobile cabin 1, which is shown in the Figure 1, suspended largely in its center of gravity line  (ie "centrally") is part of an installation of elevator, which is otherwise not represented as a drawing, with an elevator shaft, or a closed shaft structure only partially, a drive pulley drive, a counterweight and the mobile cabin represented, moving the counterweight and the mobile cabin by the guide rails essentially in vertical direction up and down and are hung here of a suspension medium, which consists of 6 round wires, used for other mobile cabin payloads, means of 4 to 12 round wire suspension (not shown in the drawing) according to the nominal load.

The forces of weight and mass presented in the mobile cabin 1 resulting from the weight of the mobile cabin and of their current payload are transmitted through the structure carrier 2 to carrier cables 3. Oppositely, the forces of cable are transmitted by supporting structure 2 to the different components of the mobile cabin, or the payload of The mobile cabin.

The bearing structure 2 is composed of two frames 2 a and 2 b. Each of frames 2 a and 2 b is closed completely along the mobile cabin 1, that is, it forms a "ring" independent. Each of frames 2 a and 2 b is constructed of hollow profiles that are essentially independent -local openings that do not substantially affect are allowed flexural strength, or torsional strength, of the respective hollow profile. In the manufacturing example shown by figure 1 are used for frames 2 a and 2 b channels planes, ie independent hollow profiles with a section rectangular, preferably one such, in which the length of the rectangle that forms the outer contour is at least 1.8 times more large than the width of that one, with a wall thickness of preferably 4 to 12 mm.

In terms of principle they could be used alternatively also hollow profiles in the form of tubes or polygonal profiles not shown here. The use of profiles Polygonal gaps is usually rather a theoretical matter, given that with the flat channels in question (compared to hollow polygonal profiles) an advantage can be achieved Optimum space with good resistance. On the other hand, particularly for reasons of resistance it may make sense use tubes instead of rectangular flat channels. On This should be discussed in detail later.

The hollow profiles that form the supports verticals are installed, respectively integrated, in the mobile cabin in such a way that one of its main surfaces large is oriented towards the wall of the hole. Preferably the opposite large main surface forms in each case on the internal side of the mobile cabin an exhibition area that integrates flush into the display surfaces of the panels sheet that forms the remaining side wall. In this way they can even put on design accents without having to face a greater expense of paint, coating or coating on the inner side of the mobile cabin This using p. ex. stands, which are painted factory or by the supplier in colors, to give contrast to p. ex. white or gray (in a word, to the divergent color) of the panels of sheet metal. This arrangement of vertical supports saves construction space and responds to the premise of taking advantage of what best possible the section of the available hole.

The hollow profiles that form the supports horizontal are, on the contrary, aligned in such a way that its small main surfaces are horizontal to achieve thus a resistance that is possibly high.

The two frames 2 a and 2 b are arranged to Some distance from each other. This distance is here so great that between the two frames 2 a and 2 b are the guide skates 8 and the Guide rails not shown here. This way you can save considerably in construction space. Well, the two frames 2 a and 2 b do not reduce the available space for the surface Usable mobile cabin base because they take up space in addition to the guide rails, but use the space of construction that by itself is available in the hollow of the elevator to the left and right next to the rails of guide.

The two frames 2 a and 2 b are rigidly joined with each other by means of bridges 4 (or by means of angles of anchor 16 which, if necessary, acts as bridges), so that a solid bearing structure in the form of a frame twin, of which each of the two frames is in shape symmetric to the side of the guide rails. This gives as result, however comparatively small flat channels,  a structure and guide that supports broadly, precisely and that It has only minimal torsion hazard. How bridges act here 4 solid support plates for guide skates and angles of anchor 16, which are also solid, for the carrying cables. It also corresponds to a function of attachment to the support stand 6 for the deflection pulley 7 fixed to the mobile cabin. But nevertheless, that is smaller in the support stand shown in figure 1 which in the case of carrier plates 4 used as bridges, so which here, if the support stand looks in isolation, in which refers to the support stand can not yet talk about a suitable bridge in terms of the invention.

The bridges 4 that act as bearing plates for guide skates 8 are made here as plates metallic that in each case are butt welded between the Small main surfaces of two facing hollow profiles that form the vertical supports. Similar metal plates are the most appropriate for the manufacture of such bridges, because it is enough to weld them in each case unilaterally with a seam at an angle, which is correspondingly well penetrated, from the Easily accessible side of the mobile cabin.

Vertical hollow profiles and profiles Horizontal holes are joined by a splice junction. For this, the vertical hollow profiles are provided in places corresponding in each case of a window 9, which crosses its two large main surfaces, whose window cuts are largely analogous to the horizontal hollow profile section. He horizontal hollow profile is then pushed through the window respective. This preferably so that the hollow profile horizontal leave the window 9 again so much that the two Hollow profiles can be welded using an angled seam. In the case of proper sizing of the window, the forces between horizontal hollow profiles and hollow profiles verticals are transmitted essentially by dragging, of so that said welding seams serve above all things to prevent the horizontal profile from sliding out of the respective vertical profile window. This way it turns out also in the case of comparatively weak sizing a particularly safe union, resistant to fatigue and over all well precalculable - a union that does not depend on the high security supplements, or material, which require the unions, which are only welded, in such places. Sewing Welding ensures the pass-through joint against sliding it can also be replaced by a cot key or a through bolt to secure accordingly. However, in these alternatives are unfavorable that occupy space with greater thickness than the extremely flat welded joint and that are more expensive in production.

In the lower area of the supporting structure 2 at least four cantilever supports 10 are welded, which are distanced from bearing structure 2 approximately vertical, which, if necessary, form together with the profiles vertical bottoms of the supporting structure 2 a support for the mobile cabin floor 13. The mobile cabin floor 13 is supported by this mode in large area and does not need to be particularly stable in itself. However, it is not completely flexible.

Well, although the mobile cabin floor 13 is supports countless points with respect to the supports vertical and cantilever supports 10 (as regards the manufacturing example shown in figure 1), however, is supported with respect to those in a certain way "floating" -It is found, interleaved with elastomeric elements 18, on these and is also acoustically decoupled from the side walls, since it is in contact with them, only by corresponding elastomeric materials. In this way, the mobile cabin floor 13 is essentially decoupled acoustically compared to the rest of the mobile cabin 1. This means that particularly the vibrations produced by the Drive pulley drive is not transmitted to the passengers as unpleasant sound propagated by solid bodies, or Whether those do not perceive those as a "vibrant floor." Yes additionally the sheet metal panels 14, 15, etc., which form the side walls and the back wall, are equipped with the outer side at least partially with soundproofing material (mats, plates, projected bitumen or similar) corresponding, as know this, for example, about building cars for the damping, or modification, of the proper frequency of large sheet metal surfaces, then a cabin can be made mobile 1 that runs very quietly and comfortably.

It should be noted at this point that between the floor of mobile cabin and cantilever supports and / or vertical supports sensors are installed, which are not represented here drawing, by which you can check the current load of the mobile cabin, or at least an excess of the maximum load of mobile cabin - almost directly measuring (and not just in the zone of inversion or suspension of the cable) the load that is over the mobile cabin, or the relative movement of the plate floor that that causes.

Moreover, the guide means of the cabin mobile, which are exemplary in the figures as guide skates 8, are not screwed directly to the bridges 4 that support them, but also with interleaved a layer of buffer elastomer (not shown in the figures). Too This substantially increases ride comfort. Alternatively guide skid supplements already manufactured with insulation, i.e. slip track linings that (in this case similar to disc brake linings of a car) they are mounted on a base plate with which they are held in the guide skate, but using an intermediate insulating layer between the base plate and the sliding track liner (in this different case of disc brake linings in the field of cars). For the same reason, in the construction shown by the Figure 1 also the support stand 6 of the deflection pulley 7 and the eyebolts 12 that hold the cable ends 11 are fixed, with interleaving of a layer of elastomer 19, to the support structure (elastomer layer of support stand 6 not shown in the drawing). While the elastomer layer 19 prevents, or decreases, the transmission of vibrations from the cables through the eyebolts to the mobile cabin, the layer of elastomer, which is not shown, between the support stand 6 It has the function of preventing, or reducing, the transmission of vibrations by means of the deflection pulley 7 to the mobile cabin. For this purpose, the support stand grabs under the horizontal supports, that is to say it is connected with these with load of compression and not with tensile or thrust load. Only this enables  Interlayer an elastomer layer without great effort.

Already these measures cushion so much, that the floor of mobile cabin 13 does not necessarily have to lean on "floating". However, preference should be given to such support, in a certain way "floating", since it strongly increases the comfort, particularly in combination with the other measures of damping

The mobile cabin of the example shown by the Figure 1 is suspended "1: 1", that is, one end of the carrier cables 3 forming the suspension means are fixed in each case in the mobile cabin 1.

However, this fixation is done in different form of what is known in the state of the art. TO know, the carrier cables are not fixed to the mobile cabin from up, coming in a vertical direction. Rather it is set to two frames 2 a and 2 b, which form the supporting structure 2, in the described mode, a support stand 6 that holds a device inverter, here in the form of a deflector pulley 7. The easel of support 6 and diverter pulley 7 are sized in this case in such a way that they do not project beyond that horizontal plane imaginary that extends here, in the construction shown by the Figure 1, by means of four upper front faces S of the vertical supports The deflection pulley 7, whose diameter is smaller which 12 times the diameter of the cable, redirects from the position vertical to horizontal, the supporting cable branches 11 that lead to the end, which is fixed to the mobile cabin, of the carrier cables The ends of the supporting cable branches 11 they are fixed in the usual way to the eyebolts 17-namely, passing the respective supporting cable through the eyelet of the screw assigned to that and fixing with a number of cable ties, the end of cable that goes out of buttonhole 12 to the section of cable that enters, so that there is a loop of cable through the eyelet 17. However, the eyelets are oriented here horizontally and not vertically as usual. The eyeglasses 17 are provided at their ends, which are oriented at anchor angles 16, of a thread, to which is bolted a nut that holds the eyebolt 17 respective in its hole at anchor angle 16 (more precisely: according to the rule, numerous nuts secured). Using the nut you can adjust the length of the different eyebolts 17 to be able to adjust, or readjust, evenly the length, or elongation, of the different carrier cables 3. This is known in itself. Unlike the state of the art, the now horizontal orientation of the eyebolts 17 facilitates, without However, substantially the adjustment, or the readjustment. The eyeglasses 17, on the other hand, are fixed using an interleaving elastic, insulating at anchor angles 16, which are shaped L-profile, which are welded between the two frames 2 a and 2 b, and which at the same time form bridges to fix frames 2 a and 2 b each other another rigidly.

This decreases considerably the space requirement in the area of the head of the hole. Because, because the cable sections 11, which due to its fixation to the eyelets cannot be used, they are now in shape flat above the roof of the mobile cabin between the eyebolts 17 horizontally aligned and small deviation 7, it is possible move the mobile cabin up until the pulley 7 and the deflector pulleys 7 or the deflection pulley corresponding to the head of the hole and the diverting pulleys 7 are directly adjacent. This form of cable fixing to the mobile cabin 1 is particularly useful in relation to the bearing structure according to the invention, because the intermediate space between frames 2 a and 2 b that otherwise it is not used, which saves considerably in space of construction in the area of the head of the hole. But this way Cable fixing eventually also provides a utility if it is done without that supporting structure and, instead, it is performs with other bearing constructions.

As recognized very well based on Figure 1 for the side walls of the mobile cabin, the two frames 2 to and 2 b that form the supporting structure 2 are integrated in the side walls of the mobile cabin. The side walls are formed by sheet metal profiles, or sheet metal panels, 14, 15, etc., as it looks pretty good in the mobile cabin door area represented by figures 1 and 2, that is to the left in the He drew. In the case of these sheet profiles, it is treated in each case originally from flat metal plates that on both sides lengths are beaded once or several times, so that you get here a kind of flange F. This flange gives them stability enough to resist the solicitations that result when goods or people to be transported are supported or supported on the wall from inside.

At the same time, the flanges make it possible to fix in a very simple way the different sheet profiles (eg 14, 16) to each other, which here are made as panels - a fixation as illustrated in Figure 7, well, it is enough to place the flange F14, F16, which results from the flange, next to each other or one inside another and then join them with each other, p. ex. by means of rivets 23, screws (not shown) or points welding 24. It is easier if the flanges (eg F14) are They provide 25 notched tabs that are intended for fit into corresponding holes 26 of flanges (eg F16) adjacent. Adjacent sheet metal panels (eg 14, 16) can then hang easily and at most they should join one with another in a few points by means of rivets, screws or Similar mentioned.

The flanges of the panels 14, 15 serve the same time to fix these panels to frames 2 a and 2 b that form the bearing structure 2. It simply lets itself collide in shape flat the flange of a sheet metal panel 14, which is adjacent to a frame 2 a or 2 b, to the respective frame and then screwed, riveted or weld the flange with the frame, if necessary, inserting a profile, or a band, of elastomer. This to avoid more intense that vibrations are transmitted from the frame to the panel sheet attached to that. In the center between the two frames 2 a and 2 b you conveniently fix a single sheet panel 15 that is folded into the edges to adjust precisely. This takes place from same way as previously described for sheet metal panels 14. Additionally, this sheet metal panel 15 can be provided with a cutout for the dashboard. In this case, at the height of cut-out provided for the dashboard, vertical support adjacent is provided with an opening, through which pass the cable set coming from the control panel and then leads inside the support, or the supports, to the ceiling of mobile cabin, like the hanging cable coming from below, which also at least use the vertical support as a protective channel of cables to reach the roof of the mobile cabin (the dashboard and the cable guides are not represented in the drawing).

As it looks pretty good based on Figure 2, the two frames 2 a and 2 b, which form the supporting structure 2, They are also integrated in the mobile cabin roof area. This It is because the two large outer sides of the brackets that run horizontally are open in each case, two large sandwich plates These are not self-supporting in the sense that they could transmit mobile cabin loads, but at least they are so rigid that the mobile cabin roof is passable to carry Out service work. Since the sandwich plates too are connected in each case with the side walls, the loads of tread caused by the assembler standing on the cab roof mobile is not only passed to bearing structure 2, but in some measure are also carried by the side walls, what which avoids an extra large overhang moment. Alternatively or for additional support of the sandwich plates, a Auxiliary frame, which is outgoing, that resists tread loads; details about it later.

As usual, on the roof of the mobile cabin a guardrail is provided that according to the size of the head of the hole is, if necessary, collapsible (not represented in the He drew).

In view of this it is evident that the construction bearing according to the invention is not only appropriate or it can be used to manufacture a single size of mobile cabins, but for a series of different mobile cabins. Namely cabins phones with a different length of mobile cabin (i.e. mobile cabin elongation perpendicular to the main plan extended by the supporting construction). I only know has, p. ex. to manufacture a mobile cabin with shorter length, which correspondingly shorten the crossbars, which are made here in the form of cantilever supports 10, and, if necessary, the sandwich plates used for the passable cabin roof mobile and install a panel less sheet metal for the side walls or a narrower special panel. This facilitates, not lastly, the manufacture of mobile cabins largely tailored for p. eg, elevator shafts, which are in projects of sanitation, with hollow sections that diverge from the norm, or than usual

In relation to figure 2 something striking is totally different. Figure 2 shows another example of manufacturing, namely an example of manufacturing, in which the mobile cabin is suspended, on top, of a flange, or be in a "2: 1" relationship. To be able to make a head of hollow as small as possible, the deflector pulleys already They are factory built with a very small diameter. To go here even more to the limit of the feasible (or, if necessary, to be able to manufacture larger diverter pulleys, which treat the cable in careful way), the diverting pulleys 20 are displaced to the same time something else inside the cabin roof area mobile. For this purpose it is planned between the two supports horizontal frames 2 a and 2 b a kind of keeper R, in which the lower half of the diverter pulleys 20. Ideally, the guard is dimensioned in such a way that the visual internal surface of the mobile cabin can continue to be made flat, that is the save not increase in size beyond the Internal surface of the mobile cabin roof. Particularly in the case of mobile cabins with a mobile cabin roof construction very thin, the guard can, however, project also to the interior of the mobile cabin. This one is there then covered with a drawer-shaped cover, which preferably it is fixed to the roof of mobile cabin in form removable from within. To gain place for the keeper (it is the same if it is now projected or not inside the mobile cabin) it is recommended in many cases to relocate the cabin lighting mobile in the direction of the lateral areas of the mobile cabin roof or eventually even in the upper part of the side walls of the mobile cabin (represented here in the drawing).

The axis 21 of the diverting pulleys is fixed between the two horizontal supports and form in the case of a union corresponding thread, if necessary, another bridge comprising the two frames 2 a and 2 b in the manner already described.

The solution of the safeguard is particularly practice in relation to the supporting structure according to the invention, but it can also be used beneficially when using another bearing structure, to continue reducing the space of necessary construction in the head of the hole.

It should still be mentioned that the twin frame according to the invention it can also be conveniently used to those mobile cabins that are suspended in the relationship "2: 1" in lower rig. The diverting pulleys to be placed then under the mobile cabin they are placed in shape corresponding according to the direction, as shown in the figure 2. The R-guard is then projected on the cabin floor mobile that now p. eg, it is made, at least by areas, of a layer or thin layer for example, in the form of a metal plate, which is flush with respect to the floor surface, which it forms a cover of the guard towards the interior space of the mobile cabin

Finally it should be noted that p. eg, it would be alternatively imaginable the use of four frames according to the type of frames 2a and 2c (eg two frames parallel, closely adjacent to this side of the rails guide and two parallel frames, closely adjacent to each other side of the guide rails) - considering, however, that the Practical person usually discards a solution of this type, due to its higher construction and material expenditure, provided that it is not merely about aspects of rights of patent.

Figure 3 shows a first example of manufacture of the bearing structure 2 according to the invention in isolated representation, that is, without the side walls, the floor and ceiling of the mobile cabin. Now they are completely seamlessly recognizable the two frames 2a and 2b that are joined with each other by means of plates 4, which form the bridges, to form a manifestly resistant twin frame, which in what essential transmits full loads from the bottom up to the means of suspension and that gives the mobile cabin its rigidity to torsion

To the supporting structure are fixed, preferably soldiers, on both sides, two auxiliary frames 27 and the crossbars 10 already addressed, made here in the form of cantilever brackets. Auxiliary frames 27 and crossbars 10 (or other auxiliary framework imaginable instead) do not take over any bearing that could be compared with that of the twin frame.

Rather, the auxiliary frame 27 serves here merely to offer support for the mobile cabin roof, or well for parts of the structure thereof, so that the roof of mobile cabin resists the tread loads that occur when travel over that one. At the same time, the auxiliary frame serves, if necessary, to make available a mounting base for the door drive.

In a comparable way it happens with the supports in cantilever As discussed above, these are only for support the mobile cabin floor in such a way that it is not subject to bending moments not allowed - that is, support the floor of mobile cabin in such a way that it just doesn't flex and maybe in this way transmit tensile forces to forming panels of side walls that, if necessary, are attached to it. There, where full support of the mobile cabin floor is necessary, install parts of the cantilever brackets, which are correspondingly cut, also in the intermediate space between frames 2a and 2b.

Apart from that it is recognized in figure 3 the cushion plate 28 which, as shown, ideally supports down against the horizontal supports and distributes in large surface intermittent damping loads before pass them to the horizontal supports. This is particularly convenient when horizontal brackets are manufactured with relatively thin thicknesses, so that it is to be feared, that of what otherwise they deform permanently by the blow of cushioning in an unfavorable case. The specialist knows that in the bottom of the hole must be provided with dampers to stop the mobile cabin, if it descends sharply in an unallowed way shortly before the bottom of the hole, and that does not require any other discussion. It should still be noted that also to the plate shock absorber 28 corresponds to a bridge function.

Alternatively, the shock absorbers to be provided in the bottom of the hole can also be arranged in such a way that butt in each case directly against one of the surfaces main of the lower horizontal supports. But nevertheless, this presupposes that these horizontal supports are used hollow profiles of corresponding thick thicknesses.

Figure 5 shows a manufacturing example slightly modified, in which the cantilever supports 10 (of which only one is fully represented in the drawing) they are made as U-profiles, or profiles in the form of tray, open upwards that house between its walls lateral elastomeric elements 18, which project towards up beyond those, for floor insulation and, given the  case, also the receivers of mobile cabin loads. In this In this case, it is not a simple replacement with respect to the Figure 3. Rather, such U-profiles were used here (which they are also placed correspondingly deep) to create construction space for elastomer elements 18 and, if necessary, the sensors (not shown, if applicable, installed parallel to the elastomeric elements) for determination of the mobile cabin load.

Figure 4 shows another manufacturing example with two variants that are even more optimized under points of view of resistance

In principle it governs that at least at the moment, in which the vertical supports of the supporting structure are made with thicknesses that are as thin as possible to save on material and weight, the strength of the union between horizontal supports and vertical supports eventually reaches their limit. Well, in the edges of the rectangular windows in the vertical supports, which serve to accommodate the supports horizontal, there is a not small notch effect considerable that considerably weakens the rest of the bearing section of the vertical supports in the area of window.

To achieve here an additional improvement can be convenient to realize the horizontal supports in the form of tubes that join in the same way, according to the sense, with the supports vertical as previously the flat channels that serve as horizontal supports This solution is made with tube 29 on the front horizontal support of the two horizontal supports of the supporting structure 2 shown by figure 4. From the round windows to be provided for the tubes is really a considerably lower notch effect, so that the vertical supports weaken substantially less by the windows

However, when using a continuous tube 29, suffers from it eventually difficulties to achieve stiffness enough to flex the horizontal supports. This can corrected in the manner illustrated on the basis of the support horizontal rear of the two upper horizontal supports of the bearing structure shown by figure 4 - the right end of the upper rear horizontal support 31 is represented by partially removed wall. Here, the construction looks that as horizontal support 31, p. eg the flat channel already used for the construction shown by the Figures 1 and 2, which, however, on its two front sides ends in each case, in a piece of tube 30 that slides to through a corresponding round window in the vertical support assigned. In this way, the advantages of the tube and flat channel or similar hollow profile. The attachement of the respective piece of tube 30 in the horizontal support (shown here in the form of the horizontal support DH corresponding to the ceiling) It is done simply and safely. Preferably, a piece of tube 30, whose outer diameter is chosen in such a way, that it is so analogous to the free internal section of the horizontal support DH, which here it is formed by a flat channel, which in the vertical direction, can be an essentially defined transmission of force, is embedded in the horizontal support DH and connected with it by means of guarantor, thread or preferably of welding.
