Abstract:
1. A guide device for guidance of a load carrier of a elevator installation along at least one guide surface, the guide device having at least one guide element which is disposed in contact with the guide surface and which is connected with the load carrier for movement relative to the load carrier between different positions in first and second positional ranges, comprising: a connecting element adapted to be connected between the load carrier and the at least one guide element, said connecting element including a first resilient element and a second resilient element arranged in series in such a manner that in the case of movement of the at least one guide element in the first positional range both said first and second resilient elements are deformed and in the case of movement of the at least one guide element in the second positional range exclusively said second resilient element is deformed; wherein an overall stiffness characteristic of said connecting element is a function of the respective position of the at least one guide element and the overall stiffness characteristic is greater in the second positional range than in the first positional range; and wherein said second resilient element has a stiffness characteristic that increases in the case of a compression of said second resilient element in the second positional range and the overall stiffness of said at least one connecting element is substantially constant in the case of a transition of the at least one guide element between the first positional range and the second positional range.
