Guide rail support assemblies for elevator systems are provided. The guide rail support assemblies include a junction element comprising a backing plate, a first extension, and a second extension, the junction element defining a rail cavity, wherein the rail cavity is configured to receive two rail sections, wherein the junction element is configured to join a first rail section to a second rail section and a mounting element configured to attach to a wall of an elevator shaft, wherein the mounting element is connected to the junction element.

A rail foot holder for fastening a rail in an elevator shaft includes a contact body defining a contact plane and at least one holding device. A first side part of a rail foot arranged between a holding head of the holding device and the contact plane to fasten the rail. A holding dimension between the holding head and the contact plane can be changed to compensate tolerances of the first side part. The holding head can be rotated about an axis of rotation into a fastening position to reduce the holding dimension. A side of the holding head facing the contact plane has a slope against the direction of rotation in at least one fastening region extending around the axis of rotation in the direction of rotation, in which fastening region at least indirect contact between the holding head and the first side part is enabled.

A method for fastening a rail of an elevator system to a bearing element fixed in an elevator shaft utilizes a clamp set having a clamp and a spacer. The clamp is arranged on a side part of a rail foot arranged on the bearing element whereby the clamp connects to the bearing element in a fastening zone of the clamp and a contact zone of the clamp is situated on a bearing side on an upper face of the side part. The spacer defines a mounting distance between the contact zone and the bearing side such that the clamp is partly elastically and plastically deformed in the fastening zone when connected. The spacer is then at least partially removed so that a distance between the contact zone and the bearing side is reduced.

An elevator system has an installation bracket fixed in an aligned manner in a region of a door-side shaft wall of an elevator shaft, wherein guide rails for guiding an elevator car arranged in the elevator shaft are fixed on the installation bracket. The installation bracket is fixed exclusively by at least one floor fixing section, wherein the at least one floor fixing section is fixed on a horizontal surface of the floor.

The invention concerns an elevator guide rail bracket for securing a guide rail section to a base via a counterpart, the guide rail bracket comprising a face, a pair of fixed claws arranged into the face, and a fastening part with fastening elements. The claws form a claw coupling with the guide rail section. The claw coupling has a fitting position and a retaining position. The guide rail bracket is attached to the guide rail section by fitting the guide rail section between the claws and turning the guide rail bracket from the fitting position to the retaining position.

The method comprises a measuring step and a separate aligning step. The alignment of guide rails supported with adjustable fastening means in the shaft is measured in several measurement points along the height of the guide rail line based on at least one reference line provided in the vicinity of the guide rails. The measurement results are stored into a memory. The guide rails are aligned based on the measurement results stored in the memory. The aligning step is carried out after the measurement results of all measurement points have been stored in the memory.

A method for fixing a rail bracket for mounting a guide rail on a shaft wall of an elevator shaft of an elevator system includes applying an adhesive layer between a support surface of the rail bracket and a final fixing region of the shaft wall in the fixed state of the rail bracket. The rail bracket is thus adhered to the shaft wall, and the rail bracket can also be additionally fixed to the shaft wall by at least one fixing element such as a nail.

An elevator system may include at least two elevator cars that are movable along a common rail section on a wall. The common rail section may comprise a plurality of rail segments arranged consecutively along a direction of travel of the elevator cars. Furthermore, the rail section may comprise at least one first rotary segment. A first rail segment of the plurality of rail segments may be arranged adjacent to the first rotary segment. The first rail segment may be fixed to the wall via a first fixed bearing such that the first rail segment is fixed in all three directions in space with respect to the wall. The first fixed bearing may be positioned at an end of the first rail segment that faces the first rotary segment.

An elevator guide rail mounting arrangement and a method for mounting an elevator guide rail using said elevator guide rail mounting arrangement. The arrangement comprises a plurality of support brackets fixed to an elevator shaft wall and a pair of spring-like fixing clips attached to each of the support. Each fixing clip comprises a first arm being fixed to the support bracket and a second arm bearing and pressing against a lateral foot flange of the guide rail. The arrangement comprises pairs of first fixing clips, which are arranged to provide a frictional holding force to resist the movement of the first fixing clips in relation to the guide rail in the vertical direction, and at least a pair of second fixing clips, which are arranged to allow movement of the second fixing clips in relation of the guide rail in the vertical direction. In the method the guide rail is mounted to the support brackets by pairs of first fixing clips and by at least a pair of the second fixing clips. The number and relative positions of the pairs of first and second fixing clips is selected on the basis of shrinkage amount of the shaft wall.

A guide rail support of an elevator includes a guide rail bracket having a first side, a second side, a first mounting portion, and a second mounting portion. The first mounting portion is attachable to an elevator shaft and the guide rail bracket has inclined apertures in the second mounting portion. An adjustment bracket is configured to contact the second side at the second mounting portion, the adjustment bracket having inclined apertures configured to align with the inclined apertures of the guide rail bracket to define stem apertures. First and second rotating members are installed through the stem apertures. Each rotating member has (i) a rotating head that movably engages with a guide rail, (ii) an integrally formed stem configured to pass through a respective stem aperture, and (iii) a middle defining a length that is greater than a thickness of the guide rail bracket and the adjustment bracket.
