Elevator guide shoe

A guide shoe for attachment to the car of an elevator and for sliding on a guide rail in a hoistway, comprising:

• a holding shoe made of rigid material and having a U-shaped longitudinal recess therein, a liner of U-shaped cross-section, said liner being made of plastic material, the liner and holding shoe being secured together by pins formed with said liner which engage in corresponding holes in the holding shoe, an intermediate layer of cellular elastomer between the holding shoe and the liner, said pins through said intermediate layer and wherein the two side walls and base of the U-shaped liner are formed as a flat laminated body, two longitudinally extending generally parallel grooves partially through the thickness of said plastic material being formed in said liner, the remaining portion of said thickness of said plastic material in said grooves forming film hinges, which permit bending up the two side walls together with the intermediate layer into its U-shaped cross section during assembly.
