Definitions

  • the present invention first of all relates to a system of elements for the assembly of a staircase.
  • the present invention relates to a system of elements for the assembly of a staircase with steps, at least part of which are winders, whereby in other words a certain angular displacement is applied.
  • the present invention also relates to a staircase, more specifically a winding stair, composed with elements of such a system.
  • a staircase is used, of course, to bridge a particular vertical distance, for example typically between different floors of a building.
  • a staircase When designing a staircase, many parameters must be taken into account . Firstly, there are the parameters which are dependent on the shape of the building and the place which is available for the staircase. Such parameters are for example the shape of the stairwell, the head (which is the total length which can be used to place the staircase) , the stair height and the passage height or headroom. Taking these parameters into account, a certain shape of staircase can be selected.
  • the simplest stair shapes are for example the straight staircase or the so-called landing stairs, whereby several landings or platforms are provided in such a landing stair, for example to change direction or to serve as a resting place in the case of longer straight stairs.
  • successive steps of the stair represent a certain angular deflection in relation to one another, such that the user, while climbing (or descending) , is simultaneously re-oriented on a portion concerned of said stair.
  • a greater height can be overcome in a much narrower place, be it by compromising somewhat on the ease of use.
  • the most extreme example thereof is a spiral staircase or winding staircase.
  • Other examples are the so-called quarter-turn staircase or double quarter-turn staircase and single or double leeward stairs .
  • the design of a staircase with winders in particular is accompanied by many difficulties.
  • angular displacement In order to achieve parts of stairs with successive steps exhibiting a certain angular deflection in relation to one another, a so-called angular displacement is usually applied, for which a number of well-known techniques exist as well, such as for example the harmonic displacement, the hoopnet method, the Leroi and Winkler method, and the infinite displacement.
  • the line on which a user is supposed to walk on the stairs which line is called the walkline, is hereby divided into equal pieces .
  • the steps are to be inserted between the outside stringers and the inner stringers and they must be fixed to the central stringer, which requires a certain manipulation of the steps for which the necessary space is not always available.
  • a specific staircase shape may in principle offer a good comfort to a user, but turn out to be impossible to achieve in practice as the connection techniques are too weak or as certain dimensions of the materials used are too restricted to withstand the forces exerted on the staircase during its use or because the stairs cannot be mounted due to lack of space.
  • Such parameters are for example the rise angle, the size of the riser and the tread, the shape of the walkline and the useful width of the stairs.
  • safety arrangements must be provided well in the form of banisters and handrails and the like.
  • the present invention aims to remedy one or several of the aforesaid disadvantages and possibly also other disadvantages .
  • the invention aims to offer a new system of elements for the assembly of a winding stair, wherein said system of elements is such that a winding stair can be obtained which is very efficient from an ergonomic point of view and as far as stability is concerned, and this for any possible situation and available space in buildings .
  • the invention aims to provide such a system of elements which allows architects, engineers and other designers to choose, as of the design stage, the most appropriate solution as far as user' s comfort and aesthetics of the staircase are concerned, wherein the available space or installation possibilities in the building must not or hardly be taken into account, and wherein the method and the system of elements are such that requirements regarding the stability or bearing power of the staircase no longer or hardly influence the exterior design of the staircase.
  • Another aim of the invention consists in providing a solution which makes it possible to obtain a computerized system wherein the design and manufacture of a winding stair is automated or can be carried out semi- automatically.
  • the aim in particular thereby is to provide a solution or method which is such that an automated system can be achieved which calculates, draws and if necessary produces a fully-fledged winding stair and all of its components on the basis of a restricted number of input data provided by a designer.
  • the idea behind the new system of elements for the assembly of a winding stair aimed by the invention should allow to achieve a design program and production software which automatically apply the knowledge of a traditional stairs maker, such that any specific stair- making knowledge is no longer required from the user to guarantee a proper production and installation.
  • the input data may for example be parameters regarding the available space, the shape of the staircase, the available machines, the type of displacement one wishes to apply, etc.
  • Another aim of the invention is to provide a system of elements for the assembly of a winding stair with which the required design time, installation time, production time and finishing time can be strongly reduced compared to the corresponding times with the known methods and systems . More specifically, a reduction of the design time, installation time and production time of around 50% is aimed for, as compared with the known methods for designing, installing and producing a staircase.
  • Another aim of the invention is to reduce the installation and manufacturing costs of a staircase to a minimum.
  • the present invention concerns a system of elements for the assembly of a staircase with steps, at least a part of which are winders, whereby the system of elements comprises at least one or several outside stringers and inner stringers and possibly intermediate central stringers, as well as steps which can be provided on the stringers, whereby at least a part of the steps are winders which are partially widened such that, after they have been provided on the stringers so as to form a staircase, the portion of the rear edge of an underlying winder at the outside stringer or outside stringers of the staircase is vertically aligned with the front edge of a superjacent step, possibly save for an overlap of a vertical step placed or to be placed on top of it and/or for forming a nosing on the superjacent step, whereas on the inner stringer or inner stringers of the staircase, the aforesaid winders exhibit a widening on their rear edges which is such that underlying winders, seen from above, extend under the respective following step over a distance which is larger than the afor
  • a major advantage of a system of elements according to the invention is that its winders are widened near the side which is designed to be fixed on the inner stringers, whereby the widening of such a step extends under a superjacent step and behind a bottom plate which may have been provided.
  • Another advantage of the widened embodiment of the steps on the side which is designed to be fixed to an inner stringer is that the winders can bear over a larger length or dimension on the inner stringer concerned, making the connection with the inner stringer or the support thereof on the inner stringer also stronger and less stressful to the materials from which both the steps and the inner stringers are made.
  • the steps can be fit together in such a manner that they cover the floor plan of the staircase to be formed, save for a possible overlap which is applied to compensate for the thickness of a vertical step or to create a nosing at the steps .
  • the stringers are provided with a phased upper section, whereby the steps can be mounted on horizontally extending parts of the phased upper sections on the placed stringers.
  • a major advantage of this embodiment of a system of elements in accordance with the invention is that the shape of the stringers makes it possible to mount the steps on top of the latter, as opposed to the known systems wherein the steps are installed in between the stringers or are incorporated in the stringers. As a result, winders can be easily applied on the stringers, so that little or no space must be available for the manipulation of the steps during their installation on the stringers.
  • Another major advantage of this embodiment of a system of elements in accordance with the invention is that the steps can be laterally arranged on the stringers more or less independently from the exact position of the stringers themselves, so that errors in the alignment of walls and the finishing of walls of the stair well have little or no influence on the shape of the staircase.
  • a winder of such a system has an outer edge designed to be attached at the respective outside stringer, and the shape of this outer edge corresponds to the shape of a fraction of the contours formed by the installed outside stringers or of the stair well in which the latter are installed.
  • a winder has an inner edge designed to be attached at the respective inner stringer and whose shape corresponds to the shape of a fraction of the contours formed by the installed inner stringers or of the stair well in which the latter are installed.
  • the inner stringer or inner stringers of a system of elements in accordance with the invention are made such that the broadened winders, after having been installed at the inner stringer or inner stringers, are fully supported over the width of their inner edges.
  • the system of elements is provided with basic elements consisting of the stringers, steps and possibly vertical steps, with which a basic staircase can be composed, and with additional elements for a superstructure with which a finishing layer can be provided on said basic staircase so as to form a finished staircase, and whereby these additional elements consist of finishing steps, finishing vertical steps and possibly intermediate elements, with which the riser of the finished staircase can be adjusted.
  • a major advantage of such a system of elements in accordance with the invention is that, already in the initial stage of a building project, a basic staircase can be installed which may serve as scaffolding stairs and which will later serve as the substructure of the ultimate staircase.

  • All the stringers 10 from figures 1 to 3 are carried out with a phased upper section 30, whereby portions 31 which are horizontally oriented during the mounting and portions 32 which are vertically oriented during the mounting alternate .
  • steps 11 are provided on the portions 31 of these phased upper sections 30 which are horizontally oriented after having been mounted.
  • steps 11 are represented in figure 4. First of all, there are a number of steps 11 which form straight steps 33.
  • These straight steps 33 have a length C, in correspondence with the width K of the staircase 4 to be formed, and a width D. Further, there is also a straight step 37 which serves to form the final step 37 of the double quarter-turn staircase 4 and which has slightly larger dimensions. At two opposite angles 38, the latter step 37 is also provided with a notch 39 designed to fit between standing portions 40 in the shape of a kind of ears 40 provided on the topmost outside stringer 14 and the topmost inner stringer 17.
  • All the other steps 11 are winders 45 designed for a winding portion of the double quarter-turn staircase 4, whereby a certain angular displacement is applied.
  • winders 45 are special, since they are not designed as is usually the case.
  • the available space for the staircase 3 on a floor plan of the stair well 5 is subdivided in a number of parts in correspondence with the number of steps 11 that will be used to overcome the difference in height between a lower floor 36 and a higher floor 42.
  • Such a floor plan or top view is represented for example in figure 5.

  • the available space is better divided over the steps 11, such that the space to place one's feet on the steps 11 is optimised .
  • an attempt is made to maintain the width of the steps 11 at the inner stringers 15 to 17 sufficiently large, both to increase the comfort of a user and to ensure the stability and bearing power of the staircase 3.
  • the winders 45 represented in figures 4, 6, 7 and 8, have a first portion 46 in the shape of a polygon whose contours correspond to the contours of steps as they are traditionally designed.
  • Such a first portion 46 is defined by an outer edge 47 whose shape corresponds to the shape of a fraction of the stair well 5 on the outer walls 6 to 8, the stair well 5 or the installed outside stringers 12 to 14.
  • such a first portion 46 with contours in correspondence with a known design is defined by an inner edge 49 whose shape corresponds to the shape of a fraction of the stair well 5 on the inner wall 6 or the installed inner stringers 15 to 17.

  • Figures 6 to 8 represent yet another dotted line 56 which is parallel to line 52 and at a distance S therefrom.
  • Said distance S is in this case equal to the thickness F of a vertical step 57 which may possibly be placed above a step 11 so as to form a closed staircase 3.
  • the vertical steps 57 are not all represented as separate in the figures, but they can be found for example in figures 9 to 13.
  • the first portions 46 are such that they can be placed adjacent to one another on the floor plan, possibly with an overlap in correspondence with the aforesaid mentioned distance S to cover a vertical step 57 or to form a nosing 58 on a step 11, whereby the first portions 46 together assume the shape on this floor plan of the portion of the stair well 5 wherein the staircase 3 is to be installed.
  • winders 45 according to the invention are specially made, whereby they are widened more specifically.
  • the winders 45 are provided with a widening 59 with which the first portion 46 is enlarged near the inner edge 49 and as of the rear edge 55 of the respective winder 45.
  • This widening 59 forms a sort of wing 59 on the first portion 46.
  • This wing 59 is such that, on the inner edge 60 of such a winder 45, the shape correspond to the shape of a fraction of the stair well 5 on the inner wall 6 or the installed inner stringers 15 to 17.
  • This inner edge 60 of a winder 45 is in other words composed of an inner edge portion 49, belonging to the first portion 46 of the winder 45 which corresponds to the contours of a traditionally designed winder, and an inner edge portion 61 which forms an extension to the inner edge portion 49, although still according to the contours of the stair well 5 on the inner wall 6.
  • the inner edge 60 of the winder 45 is designed to be attached at the respective inner stringer 15 to 17 and, thanks to its enlarged form, the step 45 there finds a better support.

  • the portion 62 of the rear edge 55 of the winder 45 which defines the widening 59 is made rectilinear.
  • the portion 62 of the rear edge 55 of the winder 45 which defines the widening 59 forms a flowing line.
  • This shape of the winders 45 is such that, after they have been placed on the stringers 10 so as to form the staircase 3, the portion 54 of the rear edge 55 of an underlying winder 45 at the outside stringer or outside stringers 12 to 14 of the staircase 4 will be vertically aligned with the front edge 50 of a superjacent step 45, possibly save for an overlap S for a vertical step 57 placed or to be placed on top of the latter and/or for forming a nosing 58 on the superjacent step 45.
  • the shape of such a winder 45 is such that, after it has been installed, at the inner stringer or inner stringers 15 to 17 of the staircase 4, the aforesaid winders 45 will be provided with a widening 59 on their rear edges 55 which is such that underlying winders 45, seen from above, extend under the respective subsequent step 45 over a distance V which is larger than the above-mentioned possible overlap S, at least in so far as such an overlap S is applied.
  • the winders 45 would thus protrude behind a possibly provided overlying vertical step 57 should such a vertical step 57 be placed with its back 63 at a distance Z corresponding to the above-mentioned overlap S from the front edge 50 of the respective superjacent step 45.
  • figure 9 represents a view on a section on the side of the outside stringer 12.
  • the portion 54 of the rear edge 55 of an underlying winder 45 is hereby vertically aligned with the front edge 50 of an overlying winder 45, save for an overlap S however, which in this case is equal to the thickness F of a vertical step 57.
  • the rectilinear portion 54 which extends as of the outer edge 47 up to the intermediate point U, after the winders 45 have been installed on the stringers 10, will be directed parallel to the front edge 50 of a superjacent step 45.
  • step 45 does not protrude from behind the vertical step 57 on the side of the outside stringer 12.
  • Figure 10 represents a section of the same winders 45, this time at the inner stringer 15.
  • the winders 45 have been enlarged with a widening 59, and the underlying step 45 protrudes over a distance V which is larger than the overlap S under the overlying winder 45, such that in this situation, the bottom winder 45 protrudes from behind the vertical step 57.
  • Figures 11 and 12 represent a similar situation, whereby this time a larger overlap S is applied, however, so as to form a nosing 58 having a width Y on the steps 45.
  • This does not change anything essential, since once more the widening 59 protrudes from behind the vertical step 57 on the side of the inner stringer 15, whereby this widening 59 can be used to better support the winder 45.
  • the inner stringers 15 to 17 are made such that the broadened winders 45, after having been installed on their inner stringers 15 to 17, are fully supported over the width of their inner edges 60.
  • the winders 45 while being installed on the stringers 10, are aligned in relation to one another, which makes their installation very easy and as a result of which the installation can be carried out by one person.
  • a number of alignment holes 64 are provided in the steps 11, in the winders 45 as well as in the straight steps 33.
  • each time three such alignment holes 64 are provided more specifically two holes 65 on the rear edge 55 of said step 11 and, in the middle between them, a hole 66 close to the front edge 50 of said step 11.
  • These holes 64 are designed to cooperate with an alignment tool 67, a possible example of which is shown in perspective in figure 14, whereas its use is illustrated in figure 15, albeit in a straight portion of a possible staircase 3.
  • This alignment tool 67 forms a kind of rack with a rectangular bottom 68, whereby three upright sections 70 are provided at an edge 69 of the bottom 68, which are perpendicular to the bottom 68 and which serve as a stop against which a step 11 can rest during the alignment.

  • the protrusion 73 is inserted in the hole 66 of the respective upper step 11, and the front edge 50 of that step 11 may rest against the stops formed by the sections 70.
  • the alignment tool 67 and the holes 64 are such that, when aligning the steps 11, at least a portion of the rear side 55 of an underlying step 11 is each time vertically aligned with the front side 50 of a subsequent superjacent step 11, in the given example save for a thickness F of a vertical step 57 of the staircase 4 to be placed, however.
  • steps 11 and vertical steps 57 are not provided up against the vertical portions 32 of the stair-shaped sections 30 of the stringers 10 but that, on the contrary, a certain space L is left.
  • a major advantage of this assembly method consists in that the steps 11 are mounted as it were almost independently from the stringers 10, so that a staircase in any shape whatsoever can be installed without any further complications, for example resulting from errors in the shell of the building or the like, and this in a very precise manner.
