Guide rail segment and guide rail arrangement for an elevator system, and corresponding production method

A guide rail segment of a guide rail arrangement for an elevator system, comprising:

• an elongated hollow profile made of bent sheet metal;
• and
• a filler material;
• wherein the hollow profile comprises:
• a groove extending in a longitudinal direction of the hollow profile, wherein the groove is formed by partial regions of the bent sheet metal, and wherein the groove forms an undercut;
• a first compartment arranged next to the groove and extending in a first lateral direction, the first compartment delimited on four sides by partial regions of the bent sheet metal, wherein the first compartment forms a first support surface for supporting the guide rail segment relative to a shaft wall of the elevator system;
• a second compartment arranged next to the groove and extending in a second lateral direction opposite to the first lateral direction, the second compartment delimited on four sides by partial regions of the bent sheet metal, wherein the second compartment forms a second support surface for supporting the guide rail segment relative to the shaft wall of the elevator system;
• and
• a third compartment arranged next to the groove and extending in a height direction transverse to the first and the second lateral direction, the third compartment delimited on four sides by partial regions of the bent sheet metal, wherein the third compartment, with opposite lateral surfaces, forms a guide surface for guiding an elevator component to be displaced along the guide rail arrangement;
• wherein each of the first, second, and third compartments is delimited on one side by a respective partial region of the bent sheet metal forming the groove;
• and
• wherein the filler material is received in the third compartment in such a manner that the filler material rests on all four sides against the partial regions of the bent sheet metal, delimiting the third compartment on a respective one of the sides.

A guide rail arrangement, comprising:

• a plurality of guide rail segments, each of the plurality of guide rail segments comprising:
• an elongated hollow profile made of bent sheet metal;
• and
• a filler material;
• wherein the hollow profile comprises:
• a groove extending in a longitudinal direction of the hollow profile, wherein the groove is formed by partial regions of the bent sheet metal, and wherein the groove forms an undercut;
• a first compartment arranged next to the groove and extending in a first lateral direction, the first compartment delimited on four sides by partial regions of the bent sheet metal, wherein the first compartment forms a first support surface for supporting the guide rail segment relative to a shaft wall of the elevator system;
• a second compartment arranged next to the groove and extending in a second lateral direction opposite to the first lateral direction, the second compartment delimited on four sides by partial regions of the bent sheet metal, wherein the second compartment forms a second support surface for supporting the guide rail segment relative to the shaft wall of the elevator system;
• and
• a third compartment arranged next to the groove and extending in a height direction transverse to the first and the second lateral direction, the third compartment delimited on four sides by partial regions of the bent sheet metal, wherein the third compartment, with opposite lateral surfaces, forms a guide surface for guiding an elevator component to be displaced along the guide rail arrangement;
• wherein the guide rail segments are arranged one after the other in a longitudinal direction and are connected to one another.

A method for producing a guide rail segment of a guide rail arrangement for an elevator system, the method comprising:

• providing an elongated hollow profile made of bent sheet metal, wherein the hollow profile comprises:
• a groove extending in a longitudinal direction of the hollow profile, wherein the groove is formed by partial regions of the bent sheet metal, and wherein the groove forms an undercut;
• a first compartment arranged next to the groove and extending in a first lateral direction, the first compartment delimited on four sides by partial regions of the bent sheet metal, wherein the first compartment forms a first support surface for supporting the guide rail segment relative to a shaft wall of the elevator system;
• a second compartment arranged next to the groove and extending in a second lateral direction opposite to the first lateral direction, the second compartment delimited on four sides by partial regions of the bent sheet metal, wherein the second compartment forms a second support surface for supporting the guide rail segment relative to the shaft wall of the elevator system;
• and
• a third compartment arranged next to the groove and extending in a height direction transverse to the first and the second lateral direction, the third compartment delimited on four sides by partial regions of the bent sheet metal, wherein the third compartment, with opposite lateral surfaces, forms a guide surface for guiding an elevator component to be displaced along the guide rail arrangement;
• wherein each of the first, second, and third compartments is delimited on one side by a respective partial region of the bent sheet metal forming the groove;
• and
• introducing a filler material into the third compartment in such a manner that the filler material rests on all four sides against the partial regions of the bent sheet metal, delimiting the third compartment on a respective one of the sides.
