- the wall element 5 is moved while elastically bent around the horizontal axis so that the first end 8 of the wall element 5 passes over the third detent 12 to rest against the second detent 11 and the second end 9 passes over the sixth detent 15 to rest against the fifth detent 14.
- the wall element 5 is allowed to return to its original planar shape so that the wall element 5 in the vicinity of the first end 8 is supported by means of the first, second and third detents 10, 11, 12 and in the vicinity of the second end 9 by means of the fourth, fifth and sixth detents 13, 14, 15.
- Fig. 7 illustrates that if the installation of the element 5 is performed manually from inside the car frame 1, the surface of the element 5 can be gripped with one gripping device 19 at the first gripping point, and with a second gripping device 19 at the second gripping point, which is a certain distance lower in relation to the first gripping point.

Figs. 10 - 13 present stages of the assembly method when installing a vertical column onto the ceiling and the floor. -
Fig. 1 shows thecar frame 1 of the elevator car. Thecar frame 1 comprises afloor 2,ceiling 3 andvertical columns 4 that connect the ceiling and the floor to each other. In the examples shown in the figures, thefloor 2 and theceiling 3 are rectangular in shape and in their corners are fourvertical columns 4 that function as corner columns, but it is obvious that thefloor 2 and theceiling 3 can be of other shapes also, such as polygonal or round, and that there can be any other suitable number of vertical columns between them. - The
floor 2 and/or theceiling 3 are preferably board of composite construction, such as inFig. 1a , consisting, in the structure illustrated, of twoplanar panels 21, which are fixed to acorrugated panel 22 situated between them. A preferred material of thefloor 2 and/or theceiling 3 is e.g. approx. 4 - 30 mm thick aluminum composite panel, sold under the trade name Doluflex, manufacturer Donati Group spa, Italy, the structure and manufacturing method of which is disclosed in publicationEP 0 939 176 B1 . The floor or ceiling of an elevator car formed from this material is very light, strong and rigid. Doluflex material is also easy to machine with conventional machining methods and machine tools. It can be drilled, milled, sawn, pressed, die cut, bent, chamfered, etc. The material has not previously been used in connection with elevators. The material of thefloor 2 and theceiling 3 can of course be any other suitable material. -
Fig. 1 also shows a wall element and/orcladding element 5 intended for installation into thecar frame 1. A wall element means an element that forms a wall or part of it. A cladding element means an element for installation on top of some other surface, e.g. a paneling element, which forms the inside surface of the elevator car. This example uses anelement 5, which is intended for installation into thecar frame 1 from the inside of it. In the example, theelement 5 is rectangular in shape. In another embodiment theelement 5 can also be a shape that differs from a rectangular shape, e.g. triangular, parallelogram or round, etc, in shape. Theelement 5 is dimensioned so that it covers the whole side wall of the elevator car such that it covers the opening bounded by theceiling 2, thefloor 3 and twovertical columns 4. To enable this kind ofelement 5 to be installed into thecar frame 1 from the inside, the material must be a material that can be bent elastically, in other words reversibly such that thewall element 5 returns to its original shape after bending. - The wall element and/or
cladding element 5 is preferably composite board, laminated board or some other similar flexible material. Referring toFigs. 4 and 5 , one preferred material of the wall element and/orcladding element 5 is approx. 2 - 4 mm thick composite board sold under the trade name Dibond (manufacturer Alcan Composites), in which acell structure 18 formed of polyethylene is between approx. 0.3 - 0.5 mm thick aluminum layers 17. This type of material is very light, so one person can lift, move and bend a panel the size of a whole elevator car wall. Dibond is also a material that can be easily machined with conventional tools. It can be sawn, drilled, milled, cut, bent, die cut, etc. Conventional joints can also be formed in it, such as rivet joints, glued joints, screw joints, crimped joints and welded joints. Surfacings can easily be formed on the surface of Dibond material by spray painting with conventional methods, patterns can be printed onto it using silkscreen printing methods, and coating layers can be laminated onto it. These properties make it a good material for cladding elements also. Dibond material has not previously been used in connection with elevator cars. -
Fig. 1 illustrates that thewall element 5 can be inclined and/or bent in order for thewall element 5 to fit inside thecar frame 1 through the opening between thevertical columns 4. - In
Fig. 2 thewall element 5 has been moved inside thecar frame 1 bent. The sectional drawing inFig. 4 shows that afirst detent 10 is arranged on the edge of theceiling 3 in thecar frame 1, against which detent thefirst surface 6 of thewall element 5 in the proximity of thefirst end 8 can be supported. Thefirst end 8 of thewall element 5 can be supported against thesecond detent 11. Thethird detent 12 extends a certain distance from thesecond detent 11 in order to extend over the top of the second surface 7 of thewall element 5. - Likewise the
first surface 6 of thewall element 5 in the proximity of thesecond end 9 can be supported against thefourth detent 13 at the edge of thefloor 2. Thesecond end 9 of thewall element 5 can be supported against thefifth detent 14. Thesixth detent 15 extends a certain distance from thefifth detent 14 in order to extend over the top of the second surface 7 of thewall element 5. - As shown in
Figs. 2 and4 thewall element 5 is moved while elastically bent around the horizontal axis so that thefirst end 8 of thewall element 5 passes over thethird detent 12 to rest against thesecond detent 11 and thesecond end 9 passes over thesixth detent 15 to rest against thefifth detent 14. - Then, as shown in
Figs. 3 and5 thewall element 5 is allowed to return to its original planar shape so that thewall element 5 in the vicinity of thefirst end 8 is supported by means of the first, second andthird detents second end 9 by means of the fourth, fifth andsixth detents -
Fig. 7 illustrates that if the installation of theelement 5 is performed manually from inside thecar frame 1, the surface of theelement 5 can be gripped with one grippingdevice 19 at the first gripping point, and with a secondgripping device 19 at the second gripping point, which is a certain distance lower in relation to the first gripping point. The wall element and/orcladding element 5 is bent by turning thegrippers 19 in relation to each other. -
Fig. 8 illustrates that the wall or its cladding can be formed from a number ofelements 5 that are smaller than the surface area of the wall and installed between thevertical columns 4 by bending them around the vertical axis. -
Figs. 2 - 6 show that support means 20 are fastened to the edge of theceiling 3 and thefloor 2, said support means forming two of the aforementioned detents, namely detents 10 and 11, as well asdetents cladding element 5. The othernecessary detents ceiling 3 and thefloor 2. - The installation method described is just as viable in newbuilding in connection with the assembly of a new elevator car, which can be performed either in the elevator shaft or outside it, as it is in connection with the modernization of an elevator car, in which the wall elements and/or cladding elements in an old elevator car are replaced with new ones, the work being performed either inside or outside the elevator car.
- Disassembly is also as easy as installation and can be performed just as well from inside or outside the elevator car. In the method for disassembly, the wall element and/or
cladding element 5 in thecar frame 1 is gripped and the wall element and/or cladding element is bent elastically into an arc so that the direct distance between thefirst end 8 and thesecond end 9 decreases. Then thefirst end 8 of the bent wall element and/orcladding element 5 is moved over thethird detent 12 away from contact with thesecond detent 11, and thesecond end 9 is moved over thesixth detent 15 away from contact with thefifth detent 14. -
Figs. 9 - 10 illustrate a preferred formation of thefloor 2, theceiling 3 and thevertical columns 4 of thecar frame 1 using the fastening of one vertical column as an example. The advantage of the arrangement is that it is possible to assemble thecar frame 1 in the elevator shaft and that thecar frame 1 can be formed to be as large as possible in relation to the space in the elevator shaft. By installing thevertical columns 4 from inside the car frame working in the manner described inFigs. 10 - 13 , the space between thecar frame 1 and the elevator shaft can at minimum be approx. 10 mm. - Fixing
bolts 23 are arranged on theceiling 3 and thefloor 2 for fastening thevertical columns 4. At the upper end and lower end of thevertical column 4 are substantially identical fixing links 24 in matching positions in the vertical direction. Both of the fixinglinks 24 comprise ahole part 25, through which the head part of the fixingbolt 23 can be passed, a verticalfirst link part 26, which extends from the hole part in the vertical direction and the width of which is smaller than the head part of the fixingbolt 23 and larger than the threaded part of the fixingbolt 23, and a horizontalsecond link part 27, which extends in the horizontal direction from the end of the first link part and the width of which is essentially of the same magnitude as the width of first link part. At first theceiling 3 is raised (with lifting equipment not presented here) above thefloor 2 to a height corresponding to the height of thevertical column 4 so that the distance between the fixingbolt 23 on thefloor 2 and the fixingbolt 23 on theceiling 3 is as great as the distance between thehole parts 25 of the fixinglinks 24 at the lower end and the upper end of the vertical column. - According to
Fig. 10 , thevertical column 4 is placed so that thehole parts 25 of the fixinglinks 24 are directly facing the fixingbolts 23. - According to
Fig. 11 , thevertical column 4 is moved so that the heads of the fixingbolts 23 go through thehole parts 25. - According to
Fig. 12 , thevertical column 4 is moved in the vertical direction guided by thefirst link parts 26 until the fixingbolts 23 meet the end of thefirst link parts 26. - In
Fig. 13 thevertical column 4 is moved in the horizontal direction guided by thesecond link parts 27 until the fixingbolt 23 is at the end of thesecond link part 27. - Finally the fixing
bolts 23 are tightened in order to fasten thevertical column 4 to thefloor 2 and to theceiling 3. - It is obvious to the person skilled in the art that the invention is not limited to the embodiments described above, in which the invention is described using examples, but that many adaptations and different embodiments of the invention are possible within the frameworks of the inventive concept defined by the claims presented below.
