Holder for mounting a guide rail for a lift on a ceiling
US 5240213 A
A holder for mounting a guide rail on a ceiling comprises a carrier defining a plane and comprised of two separate and unconnected plates attachable to the ceiling and defining a gap therebetween completely separating the two plates from each other. Guide rail holding extensions on the carrier plates at opposite sides of the gap have parts extending in a plane parallel to the carrier plane, the holding extension parts symmetrically projecting into, and engaging, grooves in the guide rail. The guide rail holding extensions have distal inclined abutment faces facing away from the groove-engaging parts, and a single wedge element is arranged between the inclined abutment faces in mating contact with therewith and wedged therebetween below the gap. Lock screws pass vertically and centrally through the wedge element and through the guide rail for affixing the guide rail to the holder, the lock screws being freely accessible through the gap between the carrier plates.
1. The combination of a guide rail and a holder for mounting sand guide rail on a ceiling, the holder comprising
(a) a carrier plate means defining a plane and comprised of two separate and unconnected parts attachable to the ceiling and defining a gap therebetween completely separating the two parts from each other,
(b) guide rail holding extensions on each of the two parts of the carrier plate means at opposite sides of the gap,
(1) the guide rail having a respective groove at each of said sides of the gap and the grooves defining a plane parallel to the carrier plate means plane, and
(2) the guide rail holding extensions having parts extending in the parallel plane, the parts of the holding extensions symmetrically projecting into, and engaging, the grooves in the guide rail, and the guide rail holding extensions having distal inclined abutment faces facing away from the parts of the holding extension,
(c) a single wedge element arranged between and in mating contact with the abutment faces of the guide rail holding extensions and is also wedged below the gap, and
(d) lock screws passing vertically and centrally through the wedge element and through the guide rail for affixing the guide rail to the holder, the lock screws being freely accessible through the gap between the parts of the carrier plate means.
2. The holder of claim 1, wherein the inclined abutment faces of the guide rail holding extensions converge towards the ceiling.
It is accordingly an object of this invention to provide such a holder for mounting a guide rail on a ceiling, in which the carrier plates may be mounted on the guide rail in a simple manner and may have a small tolerance with respect to the grooves in the guide rail.
Preferred embodiments of this invention will now be described in more detail in connection with the accompanying drawing wherein
FIG. 1 illustrates by way of example a curved path of guide rail 16 attached to a ceiling by a succession of holders 4. A typical cross section of guide rail 16 is shown in FIG. 2. each holder comprises carrier plate means extending in plane E of the ceiling and comprised of two separate and unconnected parts 7 and 8 whose margins 2 have mounting holes 3 for dowelling or bolting the carrier plate means parts to the ceiling. Parts 7 and 8 have guide rail holding extensions 6 whose parts 6' project into, and engage, grooves 5 in guide rail 16 parallel to an adjacent the plane of the carrier plate means. Guide rail holding extensions 6 have distal faces 9 facing away from parts 6' and including inclined abutment faces 10. Single wedging element 11 is positioned between the inclined abutment faces and is in mating contact with inclined abutment faces 10. Lock screws 1' pass vertically and centrally through bores 1 in wedge element 11 and through guide rail 16 for affixing the guide rail to holder 4. The lock screws are freely accessible through the gap between carrier plate means parts 7, 8. If desired, the guide rail may be further fastened to the holder through mounting holes 1" along the margins of parts 7 and 8 extending along the gap between the parts in vertical alignment with guide rail holding extension parts 6'.
