Abstract
A sliding guide shoe for an elevator has a guide shoe housing and an insert inserted into the guide shoe housing for guiding an elevator car or a counterweight. In order to positionally secure the insert, the insert has profiled pins that engage in bores in the guide shoe housing. In order to form the profiling, the pins each have radially outwardly directed ribs or projections that are distributed evenly over the circumference.
Claims13
A sliding guide shoe for an elevator to guide an elevator car or a counterweight, the sliding guide shoe having a guide shoe housing and an insert inserted into the guide shoe housing, the sliding guide shoe comprising:
- a bore formed in the guide shoe housing for positionally securing the insert;
- and
- the insert having a pin engaged in the bore, wherein the pin includes profiling in the form of a non-circular outer profile which is uniform in cross-section extending in an axial direction of the pin, the cross-section forming a star-shaped star polygon and the profiling being form-fitted in the bore.
A sliding guide shoe for an elevator to guide an elevator car or a counterweight, the sliding guide shoe having a guide shoe housing and an insert inserted into the guide shoe housing, the sliding guide shoe comprising:
- two bores formed in the guide shoe housing for positionally securing the insert;
- and
- the insert having two pins, each of the pins engaging in an associated one of the bores, wherein each of the pins includes profiling, where the profiling is formed by radially outwardly directed ribs or projections which are distributed evenly over a circumference of the pin forming a star-shaped star polygon cross-section and which are continuous along an axial direction of the pin, and where the ribs or the projections are arched radially at an outer circumference of the pin and form-fitted in the bore.
A sliding guide shoe for an elevator to guide an elevator car or a counterweight, the sliding guide shoe having a guide shoe housing and an insert inserted into the guide shoe housing, where the insert is a two-part insert having a sliding element and a damping element, the sliding guide shoe comprising:
- a bore formed in the guide shoe housing for positionally securing the insert;
- the insert having a pin engaged in the bore, wherein the pin is formed by an annular buffer element on the damping element and a retainer cam, the buffer element having profiling on an outside and a hole on an inside, and the sliding element having the retainer cam that is accommodated in the hole;
- and
- wherein the buffer element has a profiled outer contour including pre-formed indentations or elevations forming a star-shaped star polygon cross-section and being form-fitted in the bore.
