Abstract
Description
- The present invention relates to a method for the assembly of a stairlift guide rail, the method involving the use of a kit comprising a plurality of segments of guide rail, each segment of the plurality of segments comprising a first face and a second face, said plurality comprising a segment for a curved section of the stairlift guide rail,
wherein the method comprises the step of aligning the first face of a first segment with the second face of a second segment and fixing said first segment relative to said second segment. - Stairlifts are devices for transporting a person between two floors of a building, for example along a flight of stairs of a building lacking an elevator such as a home.
- A problem with retrofitting a building such as a house with a stairlift guide rail is that it is quite expensive, because of two reasons:
- the location where the stairlift guide rail is to be installed has to be carefully measured in particular if the flight of stairs comprises a turn, and
- the guide rail segments are expensive to manufacture, requiring bending equipment.
- A method according to the preamble is disclosed in
US2012/0279826 , which makes use of standardised segments to assemble the stairlift guide rail. - The versatility of such a kit of standardised segments leaves to be desired.
- It is the object of the present invention to reduce the above problems.
- To this end, a method according to the preamble is characterized in that the curved section of the stairlift guide rail comprises tapered segments, a tapered segment having the first face and the second face at an angle a of at most 16°.
- With the method according to the present invention, it is possible that only two types of segments have to be produced for a wide variety of stairlift guide rails. The tapered segments can be mass-produced, for example using an automated CNC-machine, and kept in stock as pre-fab elements, allowing for significantly quicker delivery and installation than currently possible. They may also be kept in stock at supplier level, instead of at factory level, which further increases the speed of delivery and installation. Thus a versatile method suitable for creating a variety of stairlift rail guides is provided, and logistical problems are reduced. A curve section of a desired angle can be produced by combining the appropriate number of tapered segments.
- The stairlift guide rail will have at least one groove along the path thereof for a stairlift chair to be able to move along the stairlift rail guide.
- According to a favourable embodiment, the tapered segments used for the curved section are tapered segments produced using a moulding technique, preferably by injection moulding.
- Thus the method is a more cost-effective method.
- According to a favourable embodiment, a tapered segment for the curved section comprises
- a primary side chosen from the first face and the second face, and
- a secondary side, said secondary side being the other face of the first face and the second face;
- at the primary side the segment comprises a plurality of blocking protrusions, and
- the tapered segment comprises wall sections capable of receiving said plurality of blocking protrusions of an adjacent tapered segment, wherein the primary side of a first tapered segment is aligned with the secondary side of a second tapered segment, positioning the blocking protrusions of the plurality of blocking protrusions immediately adjacent to the wall sections.
- Thus stiffness and in particular protection against torsion is provided. Preferably both the primary side and the secondary side are provided with a plurality of blocking protrusions, so blocking protrusions will be available for blocking rotation with any straight segment at either end of the curved section.
- According to a favourable embodiment, the primary side of a first tapered segment comprises a tapered protrusion extending beyond the blocking protrusions and the secondary side of a second tapered segment comprises at its secondary side holes for receiving said tapered protrusion, wherein the first side and second side are aligned by the tapered protrusion and the hole receiving said tapered protrusion before the blocking protrusions are adjacent to the wall sections.
- Thus assembly is facilitated.
- According to a favourable embodiment, a segment for the curved section comprises
- a web,
- a primary side chosen from the first face and the second face, and
- a secondary side, said secondary side being the other face of the first face and the second face;
- at the primary side the segment comprises a lip comprising a first through-hole, and
- the web defines at the secondary side a receiving recess for receiving the lip of a second segment for the curved section, and the web comprising a second through-hole,
- Thus a desired number of segments can be joined easily. The lip will be in a plane that is transverse to the line of intersection defined by the intersection of the first face and the second face. It is preferred that the lip and the recess are in line. The through-holes will in general be formed by a finishing operation after injection molding, e.g. by drilling.
- According to a favourable embodiment, a segment for the curved section comprises two segment halves, each comprising a lip and a receiving recess, and joining a segment with a bolt comprises joining two webs and two lips, the two webs and the two lips comprising four aligned through-holes.
- Such segment halves are relatively easy to manufacture. The segment halves are preferably be identical, which makes manufacturing easier.
- According to a favourable embodiment, the plurality of segments of the kit comprises a straight segment, said straight segment being formed using extrusion.
- Such a straight segment is cheap to produce and can be cut to the required length, optionally machined, and then fixed relative to a tapered segment for a curve section. This can be done at the supplier level, with concomitant advantages.
- According to a favourable embodiment, the straight segment comprises
- at least one cavity capable of receiving at least one of i) a tapered protrusion protruding from at least one of the first face and the second face of a tapered segment for a curved portion, ii) a blocking projection, and iii) a lip transverse to a primary face of a tapered segment for the curved section;
and - wall sections capable cooperating with a plurality of blocking protrusions of an adjacent tapered segment, said blocking protrusion acting as a stop for the straight segment to prevent movement of the straight segment relative to the adjacent tapered segment.
- In general, the lip received by a straight section will not cooperate with the straight segment, as a result of which it will not help against torsion forces. The protrusions, e.g. stubs, from the tapered segment will take care of that. The cavity, such as a central cavity, will preferably be capable of receiving the lip of a tapered segment in a first orientation of the face facing the face of the straight segment and at a second orientation of said face facing the face of the straight segment, the later orientation being rotated over at least one of 90° and 180°, and preferably over 90°, 180° and 270°, in a plane parallel to the face of the straight segment. Thus the method according to this embodiment is very versatile when it comes to forming a stairlift guide rail.
- According to a favourable embodiment, at least two segments of the plurality of segments comprise a slot for mounting the stairlift guide rail to a wall or the stairs.
- The slot will extend in a direction of the stairlift guide rail formed and facilitates positioning and mounting of the stairlift guide rail.
- According to a favourable embodiment, the tapered segments for the curved section comprises tapered segments with the angle a in a range chosen from i) 4.3-4.7°, ii) 4.8-5.2°, iii) 8.7-9.3° and iv) 11-11.5°.
- Thus curved stairlift rail sections with variety of angles including about 45° and about 90° can be formed. Preferably the tapered segments are chosen from at least two of said ranges, allowing a larger variety of curve section angles.
- According to a favourable embodiment, the segments for the curved section of the stairlift guid rail comprises
- segments with angle a of 5°, and
- segments with an angle a' chosen from at least one of 7° and 9°.
- The amount of work for assembly of the stairlift guide rail can be reduced with 7° and/or 9° segments compared to the use of 5° segments alone. For a 90° angle using a combination of segments with 5° and 7° angles, 14 segments suffice, instead of 18 for 5° only. In addition, it is possible to create a greater range of angles. In particular it is possible to follow a staircase more closely, because in a building walls are rarely really perpendicular or at the required geometrical angle. By way of example, for angles around 45°, the following range can be created using 5° and 7° segments: 40°(8*5°); 41° (4*5° + 3*7°); 42° (6*7°, or 5*5° +7°); 43° (3*5° + 4*7°); 44° (6•5° + 2*7°); 45° (2*5° + 5*7°); 46° (5*5° + 3*7°); 48° (4*5° + 4*7°); 49° (7*7°); and 50° (3*5° + 5*7°). For 5° and 9° segments the all these values can be covered in a similar manner. While the taper angle a of the segment doesn't need to be exactly 5° (e.g. 4.5° would work as well), the difference in angle between the segments having different angles will be close to a multiple of 2° for the best spread of angles within a range (such as from 40° to 50°), that is a multiple of a value in the range of 1.8 to 2.2° and preferably in the range of 1.9-2.1°). The multiple will be 1 or 2.
- According to a favourable embodiment, the first face and the second face of a tapered segment defining a second taper in a second direction, said second direction being a direction transverse to direction of the first taper, the second taper having an angle β of at most 16°.
- This increases the versatility of the method and the types of stairlift guide rails that can be installed. To join single and double-tapered segments, there will be an intermediate straight segment, in general of short length. For a double-tapered segment, all the variations discussed above for a single-tapered segment are possible as well, and for the second taper the angle β (and β') will have the same value or in the same value range as a (and a'), albeit independently chosen. Repetition is abstained from for the sake of brevity only.
- Finally, the present invention relates to kit for assembling a stairlift guide rail, wherein the kit comprises a plurality of tapered segments having a first face and a second face at an angle a of at most 16°.
- The invention also relates to any embodiment of such a kit (or set) discussed in the subclaims of the above method in any combination, repetition only being avoided for the sake of brevity.
