Description

Method for manufacturing a platform lift rail
Technical field
The invention refers to a method for manufacturing a platform lift rail, a platform lift rail and a platform lift having such a rail.
Technical background
EP 1 554 210 Aldiscloses a platform lift for the use of a disabled person in a wheelchair. WO 2013/129923 Al discloses a platform lift in the form of a stairlift. In both cases the platform is part of a drive unit which travels along at least one guide rail. A leveling mechanism is provided to hold the platform always in a horizontal orientation, even if the inclination angle of the guide rail is changing along the path of travel.
The invention refers in particular to the rail of such platform lifts, in which the rail has curved shape, like shown in figure 3 of WO 2015/052489 Al . Conventionally the tube shaped rails are manufactured by a prefabricated tube, to which a separate rack is welded. This requires separate bending processes for preparing the tube and the rack as well as a joining process of the complex shaped tube and rack. This kind of platform lift rail and the respective welding process is shown in the brochure "Dit is uw thuis - Swing, de traplift geschikt voor alle trappen", ThyssenKrupp Encase NV, 2016.
Disclosure of the invention
It is an object of the invention to provide an alternative method for manufacturing a rail of the aforementioned kind. This object is solved by a method, a platform lift rail and a platform lift according to the main claims. Preferred embodiments are described in the subclaims and the description.
According to the invention the method comprising: providing a sheet metal, plastic forming the sheet metal so as to form a tubular profile, thereby closing the tubular profile, and forming a projecting flange, in particular by connecting opposite faces of the sheet, permanently fixing the flange, in particular by joining the opposite faces in the area of the projecting flange, creating positive engagement means into the projecting flange.
With this method it is possible to obtain a rail including the rack in one piece without any necessity to add materials by additional joining process. The rail can be manufactured using several kinds of material, as conventional steel, stainless steel, zincked steel, and others ductile/moldable materials. The inventive method enables advantages with regard to cost and stability, at the same time using a very simple primary material.
The platform lift, for which the invention is applicable, comprises at least one rail and a driving unit adapted for driving along the rail. The invention is in particular applicable for a single rail platform lift, which requires exactly one rail for guiding the drive unit. Also the invention is applicable to a double rail platform lift, which in particular requires exactly two rails running in main parallel to each other. The invention is particularly applicable to rails, which deviate from a straight lined shape, thus wherein the direction of travel is curved. "Curved" means in this regard "not straight lined". The term "plastic forming" means particular manufacturing processes, which make use of suitable stresses to cause plastic deformation of the materials to create a desired shape. The applied manufacturing processes are in particular bending, high pressure forming, rolling.
The material defining the rail is in particular solely provided by sheet metal. No other material is then necessary to be joined to the sheet, except material for surface treatment, like color or anticorrosive coatings. To obtain sufficient stability the thickness of the sheet material may be increased or the shape of the tubular section may be selected to support the loads applied to the rail.
In a second step of plastic forming the rail is provided with a curved travel direction. Here the rail can freely be shaped according to the spatial needs defined by the installation situation at the stairway. Nearly every configuration may be possible due to the formability of the sheet metal. Thereby during the second step of bending the cross section of the tubular profile is preferably maintained. Small deviations of the cross section during the course of the rail may be covered by the term "maintained", which still allow, that the drive unit is able to drive along the entire rail.
Preferably an enforcement bracket is inserted into the flange, in particular between the opposite faces to be connected. This may selectively increase the stability of the rack section, without the need to use much thicker sheet metal at the tubular section.
Preferably during first plastic forming the opposite faces of the sheet metal come to rest on each other with the same surface. This enables to create the flange easily. The inventive rail is characterized in that at least parts of the rack section and at least parts of the tubular section are made from one piece, in particular from the same sheet metal. Preferably at least parts of the positive engagement means and at least parts of the tubular section are made from one piece, in particular from the same sheet metal.
The described advantages and embodiments regarding the method are applicable to the inventive rail and vice versa.

c) a generic platform lift in a third embodiment;
figure 2 a conventional rail for a generic platform lift;

Description of an inventive embodiment
Figure 1 shows three exemplary embodiments of a generic platform lifts 1, to which the invention can be applied. In figure la a platform lift 1 for the use with a wheelchair is shown. The platform 8 therefore comprises a kind of lifting ramp, which can travel along a direction of travel D from a first lading area 4 to a second landing area 5. The direction of travel D is defined by a rail 2, and is driven in main by the course of an existing stairway 3 in a house. An alternative embodiment is shown in figure lb wherein the platform 8 comprises a seat.
The rail of the platform has in particular a curved shape, which deviates from a straight line; thus the direction of travel will change at least once during the course of the rail 2.
The platform 8 is part of a driving unit 6, which further comprises a carrier 7. The carrier has non shown rollers, which roll along the rail 2. For driving the carrier positive engagements means 13 (only shown in detail in figure lb) are provided on the rail 2, which cooperates with driving means, in particular a driven pinion (not shown), of the carrier 6. A leveling mechanism 9 is provided on the drive unit, to keep the platform 6 always in a horizontal orientation, even if the inclination of the rail 2 varies during its course.
Figure lc shows a platform lift in main similar to the lift of figure la. The lift comprises two rails, which are arranged in main parallel to each other. The distance of the two (in main parallel) rails is varying during the course of travel; this variation of the distance may be the input value of the leveling mechanism.
Figure 2 shows a conventional rail (cross section and side view). The rail 2 comprises a tube 11 and a rack 12. The rack 12 is joined to the tube e.g. by welding or gluing (see exemplary weld seam 18). The rack 12 comprises said engagement means 13.
Figure 3 shows a sheet metal 20, out of which a rail 2 suitable for the platform lifts 1 of figure la and lb is manufactured.
In a first bending step (figures 4 and 5) a tubular profile 21 is created out of a central area of the sheet metal 20. Two faces 25 of the sheet metal 20 are bend in way, so that the faces 25 abuts each other at the same upper surface U of the sheet metal 20. The lower surface L of the sheet metal forms the outer surface in all areas of the cross section of the bent sheet metal 20.
Consequently, the two faces 25 form a projecting flange 22, which projects radially from the tubular section 21. The term "radially" is in this context to be understand broadly. As evident from figure 5 the term radially does not need a geometrical exact circle, to which it refers.
Additionally figure 12 shows an alternative cross section; here the projecting flange 22 is oriented out of square regarding an imaginary center axis 26 of the profile. So the term radially projecting, roughly speaking, means that the flange points away from the tubular section 21.
As an example the first plastic forming step comprises two bending substeps, which are illustrated in figures 4 and 5, each using a bending apparatus 14, 15; nevertheless, any other suitable kind of forming process may be used within these substeps, in particular high pressure forming, rolling, etc.
Subsequently, the faces 22 are permanently fixed to each other, in this embodiment by spot welding, using a spot welding apparatus 16. Figure 7 shows the resulting rail 2 comprising a number of welds spots 24. In a subsequent step the positive engagement means 13 are introduced into the flange. Here in particular a material removing process is suitable, in particular laser cutting, machining (e.g. milling), etc.
Different kind of positive engagement means 13 can be produced; exemplary in figure 8 on the left side a notch 23a and on the right side a rectangular hole 23 is shown, merely for illustration purposes. In particular by laser cutting, nearly every form can be produced.
For most stairway applications the rail 2 needs to be adapted to an individual curvature of the stairway. The rail 2 of figure 8 is subsequently (figure 9) bent in a second plastic forming step, to adapt the rail to the desired course of the travel direction. For this second plastic forming step several processes can be used: e.g. using a mold with two pieces, each one defining the complementary shape of the final shape of the rail, without the needs a the mandrel inside. Alternatively it is possible to bend only with a simple mold, by using with a rigid, semi-rigid or flexible mandrel.
As obvious from figure 9, during the second forming step the cross section of the tubular section not changed, disregarding any minor deviation in the cross-section technically caused by the forming. If necessary a mandrel 17 can be placed within the tubular profile 21 to prevent the tubular profile from being chewed.
As a mandrel 17 a coil spring may be used; the advantage is that this kind of mandrel can be pulled out of the tubular profile 21, after the tubular profile 21 is formed into a curved shape during the second plastic forming step. In this particular embodiment shown in the figures, the tubular profile 21 has a shape which deviates from a circular cross-section more into a rectangular cross section; here the use of two mandrels 17 is advantageous, which together reproduce in main the cross-section of the tubular section 21.
Figure 10 shows an improvement of the aforementioned method. Prior to permanently fixing the faces 25 to each other, a reinforcement bracket 19 is put between the faces 25. During welding the bracket 19 is also permanently fixed between the two faces 25, which are now indirectly connected to each other (figure 11), thus improving the stability of the flange 22. Figure 12 illustrates, that by the inventive method rails of various cross-sections can be created, which is only limited by general restrictions of the respective forming method.
Even if the preferred embodiment is described my means of a bending step for the plastic forming, the advantages and embodiments described here a re also applicable to any other plastic forming process.
