Definitions

  • 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:
  • 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 ⁇ of at most 16°.
  • 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.
  • 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.
  • the tapered segments used for the curved section are tapered segments produced using a moulding technique, preferably by injection moulding.
  • a tapered segment for the curved section comprises
  • 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.
  • 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.
  • a segment for the curved section comprises
  • 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.
  • 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.
  • segment halves are relatively easy to manufacture.
  • the segment halves are preferably identical, which makes manufacturing easier.
  • 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.
  • the straight segment comprises
  • 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.
  • 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.
  • the tapered segments for the curved section comprises tapered segments with the angle ⁇ 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°.
  • curved stairlift rail sections with variety of angles including about 45° and about 90° can be formed.
  • the tapered segments are chosen from at least two of said ranges, allowing a larger variety of curve section angles.
  • the segments for the curved section of the stairlift guide rail comprises
  • 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.
  • the following range can be created using 5° and 7° segments: 40° (8 ⁇ 5°); 41° (4 ⁇ 5° + 3 ⁇ 7°); 42° (6 ⁇ 7°, or 7 ⁇ 5o + 7o); 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°).
  • the all these values can be covered in a similar manner.
  • the taper angle ⁇ 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.
  • the stairwell 190 is provided with a stairlift guide rail 100 according to the invention.
  • Fig. 2 shows a composite section 201 of the stairlift guide rail 100 of Fig. 1 as a side view.
  • the composite section 201 shown comprises a tapered segment 210 (i.e. a wedge-shaped segment) and a straight segment 250.
  • Each segment comprises a first face 211 and a second face 212, which in Fig. 2 have been indicated for tapered segment 210.
  • These faces define, in the embodiment shown, a taper of 5°.
  • the faces run parallel.
  • the segments of the stairlift guide rail 100 are connected using a bolt 231 and a nut. To this end, the segments comprise lips.
  • Fig. 2 shows a lip 220 of the tapered segment 210, comprising a through-hole 221 for a bolt 231.
  • the segments may be provided at a face with stubs 222 that engage an adjacent segment to prevent rotation and may contain tapered nobs 223 which will protrude beyond the stubs 222 and facilitate joining two segments together.
  • Fig. 3 shows a front view of a tapered segment 210 of the composite section 201 of Fig. 2 .
  • the tapered segment 210 is a single-piece object that comprises a web 360 provided with lobes 361 defining grooves 362. These grooves 362 serve as a guide for a carriage comprising a chair.
  • the grooves 362 may be curved, in particular for tapered segments having large taper angles ⁇ .
  • the tapered segment 210 comprise tapered recesses for receiving a tapered nob 223 to as to facilitate the aligning and joining of two tapered segments 210. Once aligned, the stubs 222 will be immediately adjacent to the wall of a lobe 361. Thus adjacent segments cannot rotate with respect to each other.
  • the tapered segments 210 comprise lips receiving recesses 351 for receiving a lip 220 of an adjacent tapered segment. To this end the lips 220 will not completely fill the lip receiving recesses 351, so as to be able to be received in at choice the lip receiving recess of an adjacent tapered segment 210.
  • the tapered segments may comprise holes 364 for a self-tapping bolt or threaded holes for a regular bolt.
  • the holes will also be used for connecting a straight segment.
  • Fig. 4A and Fig. 4B show a curved section 401 of the stairlift guide rail 100 of Fig. 1 as a perspective view and a side view respectively.
  • the curved section 401 comprises a plurality of tapered segments 210.
  • each tapered segment 210 comprises two identical segment halves 410.
  • the production of segment halves facilitates production thereof using moulding such as injection moulding at reduced cost.
  • the segment halves 410 are connected to the curved section 201 using bolt 231 and nut 432.
  • the web 360 also comprises a through-hole 364, and to add a tapered segment 210, a first segment halve 410 receives a lip 220 protruding from the curved section 401, and lip 220' is received in a lip receiving recess 351 of the curved section 401.
  • the web 360 of each segment half comprises a through-hole 221'.
  • a single bolt 231 will pass through two through-holes 221' of two webs and two through-holes 221 of two flanges.
  • the straight segment 250 comprises a base 560 comprising a slot 561, here two, with which it may be attached to a wall of the stairwell 190, or to the top face 194 of a step of the flight of stairs 191.
  • a mounting bracket preferably adjustable in length, will be used, as is known in the art.
  • the mounting bracket may have a slot running in the transverse direction for optimum positioning.
  • the mounting bracket may be screwed or bolted to the step or wall, and the segment may be bolted to the mounting bracket.
  • the straight segment 250 will be of the desired length, produced by extrusion and cut to a desired length.
  • the lip of said tapered segment 210 will be received in a central cavity 565 of the straight segment 250, but is not connected to it.
  • the stubs 222 of the tapered segment 210 will be received in the cavities 565' of the lobes 361' of the straight segment 250 and be immediately adjacent to the wall 566 of the lobes 361', thus preventing rotation of the straight segment 250 with respect to the tapered segment 210.
  • the two parts are connected using a bolt, such as a self-tapping bolt, which will be introduced into the holes 364'.
