Abstract
A sliding guide shoe for guiding a moving component in an elevator shaft includes a supporting surface, and a sliding part disposed to be supported by the supporting surface. The supporting surface and the sliding part have contact through contact points where the supporting surface of the frame part is in contact with the outer surface of the sliding part. The contact points constitute a minor fraction of the corresponding surface of the outer surface of the sliding part and provide for at least one of the supporting surface and the sliding part the capability to bend for absorbing guide rail imperfections.
Claims17
A sliding guide shoe for guiding a moving component in an elevator shaft vertically along a guide rail, the sliding guide shoe comprising:
- a frame part comprising a supporting surface, and a sliding part supported by the supporting surface,
- the sliding part comprising
- an inner surface configured as a sliding surface against the guide rail, and
- an outer surface arranged against the supporting surface,
- wherein
- the supporting surface and the sliding part contact each other through contact points at which the supporting surface of the frame part is in contact with the outer surface of the sliding part,
- said contact points comprise a fraction of a corresponding surface of said outer surface of the sliding part,
- the contact points are configured to provide at least one of the supporting surface and the sliding part a capability to bend for absorbing guide rail imperfections, and
- at least one of the contact points comprises a tab on the frame part, the tab is configured as partly cut away from the frame part and configured to elastically bend under loads caused by the guide rail imperfections.
A sliding guide shoe for guiding a moving component in an elevator shaft vertically along a guide rail, the sliding guide shoe comprising:
- a frame part comprising a supporting surface, and a sliding part supported by the supporting surface,
- the sliding part comprising
- an inner surface configured as a sliding surface against the guide rail, and
- an outer surface arranged against the supporting surface,
- wherein
- the supporting surface and the sliding part contact each other through contact points at which the supporting surface of the frame part is in contact with the outer surface of the sliding part,
- the contact points comprise a fraction of a corresponding surface of said outer surface of the sliding part,
- the contact points are configured to provide at least one of the supporting surface and the sliding part a capability to bend for absorbing guide rail imperfections,
- the frame part is configured as a skeleton-structure including empty spaces that alternate with ribs, and
- the supporting surface is arranged in said ribs comprises contiguous U-shaped surfaces of the ribs that surround the sliding part.
A sliding guide shoe for guiding a moving component in an elevator shaft vertically along a guide rail, the sliding guide shoe comprising:
- a frame part comprising a supporting surface, and a sliding part supported by the supporting surface,
- the sliding part comprising
- an inner surface configured as a sliding surface against the guide rail, and
- an outer surface arranged against the supporting surface,
- wherein
- the supporting surface and the sliding part contact each other through contact points at which the supporting surface of the frame part is in contact with the outer surface of the sliding part,
- said contact points comprise a fraction of a corresponding surface of said outer surface of the sliding part,
- the contact points are configured to provide at least one of the supporting surface and the sliding part a capability to bend for absorbing guide rail imperfections,
- the sliding guide shoe further comprising a spring element between the frame part and a back wall of the sliding part,
- the spring element including a first end and a second end opposite the first end, the first end and the second end configured to be insertable into respective attachment holes of the frame part.
