Abstract
A guide rail system for guiding an elevator car or a counterweight in an elevator shaft includes a pair of .OMEGA.-shaped guide rails (1, 2) having adjacent ends connected by a connecting element. The guide rails (1, 2) have a hollow cylinder-shaped rail body (3) with a pair of flat ends (4, 5). The connecting element includes a tube-shaped connecting member (6) inserted into the rail bodies and a base plate (7, 7a, 7b, 7c) placed under the free ends (4, 5) and attached thereto by fasteners (12). A wedge body (10, 10a, 10b) on the base plate (7, 7a, 7b, 7c) extends into an opening (11, 15) formed in the connecting member (6) to expand the connecting member into locking engagement with the guide rails (1, 2).
Claims7
A connecting element for guide rails (1, 2) utilized to guide an elevator car or a counterweight in an elevator shaft, the guide rails having a hollow cylinder-shaped rail body (3) and free ends (4, 5), comprising:
- a tube shaped connecting member (6) for insertion into adjacent ends the two guide rails (1, 2), said connecting member having at least one opening (11, 15) formed therein;
- and
- a base plate (7, 7a, 7b, 7c) having at least one wedge body (10, 10a, 10b) extending therefrom whereby when said connecting member (6) is inserted into the adjacent ends of the guide rails (1, 2) and said base plate is placed under the free ends (4, 5) of the guide rails, said wedge body extends into said opening (11, 15) in said connecting member for expanding said connecting member into locking engagement with the guide rails.
A guide rail assembly utilized to guide an elevator car or a counterweight in an elevator shaft comprising:
- at least a pair of guide rails (1, 2) each having a hollow cylinder-shaped rail body (3) and free ends (4, 5);
- a tube shaped connecting member (6) inserted into adjacent ends of said guide rails (1, 2), said connecting member having at least one opening (11, 15) formed therein;
- and
- a base plate (7, 7a, 7b, 7c) having at least one wedge body (10, 10a, 10b) extending therefrom, said base plate being placed under said free ends (4, 5) of said guide rails (1, 2) and said wedge body extending into said opening (11, 15) expanding said connecting member (6) into locking engagement with said guide rails.
