Definitions

  • the present invention relates to mountings for guide rails. More particularly, but not exclusively, it relates to an improved spring clip type of mounting for lift guide rails.
  • spring clips may be expensive but, in general, have good characteristics as mountings in that they are of reasonable strength, resilience and slidability and ' are extremely easy to use.
  • a further alternative is use of constraining clips. These are designed to constrain and support the rail in a horizontal plane but to allow it to move freely in a vertical plane. Theoretically, the clamping force between rail and clip is nil, although this theoretical optimum is difficult to achieve as it relies on the skill and care of the installation personnel to ensure that the rail is constrained yet not actually clamped. Also, this type of clip has no effective ability to correct for guide rail manufacturing errors since it is not intended to generate clamping forces. Furthermore, it is possible that if there is continual relative movement between the rail and the clip, there may be a loss of constraint due to brinelling of the parts and therefore the clip may need to be adjusted in service.
  • a lift guide rail mounting comprising support bracket means affixable to a lift shaft wall, a pair of U- shaped spring clips adapted to be so affixed to a face of said support bracket means that one arm of each clip bears against the support bracket means to prevent lateral movement of the clips and the other arm of each clip bears on a lateral flange of the guide rail urging it towards the support bracket means, and a respective pair of shoulder screw means to affix the clips to the support bracket means, each shoulder screw means passing through apertures in both arms of the clip and having a shoulder adapted to tighten against the arm of the clip adjacent to the support bracket means and a head spaced from the shoulder by such a distance that it does not bear on said other arm in normal use of the clip but does bear on said other arm if the flange of the rail held by the arm is subjected to a force in an outward direction with respect to the support bracket means.
  • the pair of shoulder screw means may comprise a pair of shouldered bolts cooperable with a respective pair of nuts, said nuts being spaced a predetermined distance apart by spacer means.
  • the support bracket means may have transversely elongate apertures through which said shoulder screw means may be fixed, whereby the rail can be aligned vertically with both shoulder screw means in place, and each shoulder screw means may then be tightened to hold the rail in place.
  • each clip comprises a bearing zone of comparatively lower frictional resistance, said zone being adapted to bear on the flange.
  • the zone may be a button or stud of material such as stainless steel.
  • a bearing area of comparatively lower frictional resistance may be interposed between the rail and the support bracket means.
  • the support bracket means may comprise first and second substantially right angled brackets, said first bracket being fixable to the wall of the lift shaft, the second bracket providing a surface against which the rail may be affixed, the first and second brackets being so connected that the distance between said face of said second bracket and the wall of the lift shaft is adjustable.
  • FIGURE 1 is a perspective view of a guide rail mounting embodying the present invention.
  • FIGURE 2 is a plan view of the guide rail mounting.
  • a lift guide rail 9 comprises a generally T- shaped section of which one arm comprises the guide rail itself, while the other two form a pair of flanges attached to the foot of the guide rail. As stated above, it must be free to move in a longitudinal direction to accommodate differential expansion between the guide rail and the building in which it is set or to accommodate settlement of the building. It must also be aligned transversely so that the entire guide rail is absolutely vertical or as near as can be managed, so that the lift is not shaken or misaligned during its journey.
  • a support bracket for the guide rail comprises a pair of connected substantially right angled brackets 3,13.
  • the first bracket 13 is fixed to the wall of the lift shaft by means of bolts or the like passing through apertures 12.
  • the second bracket 3 is attached to the first bracket 13 by means of bolts 14 cooperating with nuts 16, a pair of nuts 16 being affixed to a spacer plate 15 to allow easier connection.
  • a vertically disposed face 3a of the second bracket 3 can thus be arranged at a predetermined distance from the wall of the lift shaft. This face 3a is adapted to receive the guide rail 9.
  • the guide rail is held by a pair of spring clips 1 , held to the face 3a of the bracket 3 by means of respective shoulder screws 2.
  • the spring clips are each of U shape and preferably comprise hardened tempered steel.
  • the U shape includes a first arm 1a and a second arm 1b, the latter of which is intended to abut the vertical face 3a of the support bracket.
  • Each arm of the U is provided with an aperture to accommodate the shouldered screw 2.
  • Each shouldered screw 2 has a hexagon head and a shoulder spaced longitudinally (in the direction of the screw thread) therefrom by such a distance that the shoulder contacts the inner arm 1b of the U while still allowing a distance of between 0.5 and 1.5 mm between the head of the screw and the outer arm 1a of the U-clip.
  • the pair of shouldered screws 2 each engage with nuts 4 affixed to a spacer plate 8 on the remote side of the face 3a.
  • the U-shaped spring clips operate in the manner of spring clips, holding flanges of the rail against the face 3a.
  • the shouldered screws 2 may be almost tightened to hold the flanges of the rail 9 and then moved transversely as a pair, still holding the rail 9, in transverse slots 10 of face 3a.
  • the guide rail can thus be aligned to be vertical. The screws are then further tightened to hold the rail fixedly in such a predetermined disposition.
  • the bearing force on the rail is not unduly great and therefore the rail can slide vertically within the clips.
  • the clips are provided with buttons 6 of stainless steel which has a lower coefficient of friction than the material of the clip itself. It is also less prone to corrosion and thereby damage to its surface which might increase the coefficient of friction.
  • a slide plate 7 is provided between the rail 9 and the face 3a to allow easier movement between the rail 9 and the face 3a.
  • the support brackets are attached to the wall of the lift shaft arid the guide rail or guide rail section is placed more or less in position.
  • the clips 1 are then applied but the shouldered screws 2 are not fully tightened into their nuts 4.
  • the guide rail 9 is then aligned vertically and at least one of the nuts 2 is tightened to hold the rail in place.
  • the other clip will move, by virtue of the spacer plate 8, as the first mentioned screw moves. This second screw can be tightened later.
  • the clips 1 act as spring clips allowing vertical movement of the guide rail 9 but preventing movement of the guide rail flanges away from the face 3a. If the force on the guide rail 9 should be such as to cause some pivotal movement about an end edge of a flange of the guide rail, the clip against which the force is exerted will allow such movement until the outward face 1a of the clip contacts the head of the screw 2. At this point, the load is relieved from the bend of the U- clip and transferred to a point of the clip in contact with the head of the screw 2. Thus the spring characteristics of the clip change markedly, strengthening perhaps by as much as three times. Accordingly, unless the force on the guide rail is extra-ordinarily excessive, the guide rail will still remain held within the clip 1.
  • the mounting embodying the present invention will allow vertical movement of the guide rail 9 whilst still preventing such transverse movement as would cause a flange of the rail to distance itself from the face 3a by as little as 1 mm. Since both shoulder screws 2 are attached to a spacer plate 8, the final adjustment of both clips, and hence the rail 9 held by them, may be easily accomplished. Expected forces on the guide rail 9 are accommodated in the same manner as they would be for normal spring clips, but there is a measure of safety in that extraordinary deflections of the guide rail are prevented by virtue of the heads of the screws 2 contacting the outer arm 1a of the spring clips.

Abstract

Un montage de barre conductrice disposée dans un ascenseur comprend un support (3, 13) que l'on peut monter sur la paroi d'un d'ascenseur. Une paire de pinces à ressort en forme de U (1) peuvent se fixer à une surface dudit support (3) de sorte qu'un bras de chaque pince (1) s'appuie contre le support (3), ce qui empêche le mouvement latéral des pinces. L'autre bras de chaque pince (1) s'appuie sur une bride latérale de la barre conductrice, la poussant ainsi vers ledit support. Une paire de boulons à embase (2) servent à attacher les pinces audit support. Chaque boulon à embase, qui passe à travers une ouverture pratiquée dans les deux bras de la pince (1), est doté d'un rebord apte à se serrer contre le bras de la pince (1) adjacent au support. Le boulon à embase est également muni d'une extrémité écartée dudit rebord sur une distance telle qu'il ne s'appuie pas sur l'autre bras lors de l'usage habituel de la pince. Le boulon s'appuie sur ledit bras seulement au cas où on applique une force à la bride de la barre retenue par le bras dans un sens s'éloignant des moyens de support.
