A clip for attaching an elevator guide rail to a support bracket includes: an attachment part for attaching the clip to the support bracket; a clamping part for clamping the guide rail against the support bracket; a pin guided in the clamping part and movable between a pushed-in position and a protruding position, in which the pin protrudes from the clamping part; a spring element arranged inside the clamping part and biased against the movement from the protruding position into the pushed-in position; wherein the clamping part includes a clip friction surface for touching the guide rail, when the pin is in the pushed-in position, and the pin includes a pin friction surface for touching the guide rail, when the pin is in the protruding position, which pin friction surface has a lower friction coefficient than the clip friction surface.

A rail fastening system fastens a rail of a vertically movable elevator system car has a first clamp connected to a holding structure, and a second clamp connected to the rail. The first clamp has a laterally extending first central part connectable to the holding structure and the second clamp has a laterally extending second central part connectable to the rail. Each clamp has two tabs attached in the lateral direction at opposite ends of the respective central part. A first tab of the first clamp can be connected to one of tabs of the second clamp on a first contact surface, and a second tab of the first clamp can be connected to the other of the tabs of the second clamp on a second contact surface. A first plane runs through the first contact surface and intersects with a second plane that runs through the second contact surface.

A wall securing assembly is integrated into an elevator shaft wall for securing a guide rail to the wall. The wall has a first concrete region that is reinforced with reinforcements and a second concrete region that is not reinforced. The second region covers the first region and has a surface that is exposed to the surroundings. The securing assembly has an elongated profile of C-shaped cross-section embedded solely into the second region and oriented in the vertical direction of the wall. Since tensile forces acting on a guide rail in an elevator shaft are very low, it is acceptable to secure the guide rail to the profile that is cast into the second region covering the reinforcement. The profile is anchor element-free and can be arranged in the wall vertically whereby guide rail holding consoles can be secured to the profile at any height.

An elevator system, including at least one first guide rail, which is oriented in a first, in particular vertical, direction, at least one second guide rail, which is oriented in a second, in particular horizontal, direction, a plurality of rotatable rail segments, wherein at least one thereof is transferable between an orientation in the first direction and an orientation in the second direction, at least one elevator cab, which is transportable along the guide rails and which, via the rotatable rail segments, is transferable between the different guide rails, at least one third guide rail, which is oriented in a third, in particular horizontal, direction, and wherein at least one of the rotatable rail segments is transferable between an orientation in the first or second direction into an orientation in the third direction.

The invention relates to an elevator arrangement comprising an elevator shaft wall; and a guide rail line extending vertically at a distance from the shaft wall, the guide rail line being fixed to said wall with plurality of fixing brackets; and an elevator car vertically movable along at least said guide rail line; and a hoisting machine mounted at a first vertical level between the shaft wall and the guide rail line; and a hoisting roping movable with said hoisting machine, and connected to the elevator car; wherein the guide rail line extends in vertical direction past the hoisting machine the upper end of the guide rail line being higher than said hoisting machine, and said plurality of fixing brackets comprises one or more first fixing brackets higher than said hoisting machine, by which one or more first fixing brackets the portion of the guide rail line which portion is higher than said hoisting machine is fixed to the shaft wall; and wherein the hoisting machine comprising a motor and a rotatable drive wheel. The elevator arrangement comprises an elongated hoisting passage extending vertically between the shaft wall and the guide rail line inside which hoisting passage the hoisting machine fits to be hoisted, each said first fixing bracket being shaped to circumvent the hoisting passage. The invention also relates to a method of constructing an elevator.

A fastening system has two fastening elements for mounting a bracket of a rail system of an elevator installation. The fastening elements each have a clamping plate having a through-hole and a receiving sleeve receiving an anchor bolt. The receiving sleeves each have a through-opening for the anchor bolt and an angularly movable ball joint is formed between the clamping plate and the receiving sleeve.

In a method for carrying out an installation process in an elevator shaft of an elevator system, an assembly device is inserted into the elevator shaft. The assembly device includes a support component, a mechatronic installation component retained by the support component and a control apparatus. At least one assembly apparatus (tool, sensor or component) is arranged on the support component. The support component is fixed in a fixing position in the elevator shaft. After the support component has been fixed, an actual position of the at least one assembly apparatus is determined relative to the installation component. Using the determined actual position relative to the support component, the at least one assembly apparatus is received by the installation component and an assembly step is carried out using the received at least one assembly apparatus.

A clip for attaching an elevator guide rail to a support bracket includes: an attachment part for attaching the clip to the support bracket; a clamping part for clamping the guide rail against the support bracket; a pin guided in the clamping part and movable between a pushed-in position and a protruding position, in which the pin protrudes from the clamping part; a spring element arranged inside the clamping part and biased against the movement from the protruding position into the pushed-in position; wherein the clamping part includes a clip friction surface for touching the guide rail, when the pin is in the pushed-in position, and the pin includes a pin friction surface for touching the guide rail, when the pin is in the protruding position, which pin friction surface has a lower friction coefficient than the clip friction surface.

A fastening module, for fastening a rail foot of an elevator rail to a fastening plane, includes a first fastening device fastened to the fastening plane and holding a first side of the rail foot, and a second fastening device fastened to the fastening plane and holding a second side of the rail foot. The second fastening device can be moved at least substantially in parallel with the fastening plane. At least one element of the second fastening device, which interacts with a top side of the rail foot facing away from the fastening plane, can be rotated about an axis of rotation of the second fastening device perpendicularly to the fastening plane over the top side of the rail foot from laterally outside of the rail foot. A method for fastening a rail foot utilizes a plurality of the fastening modules to fasten elevator rails of an elevator system.

A fastening device, used to fasten a face of an elevator rail foot relative to a fastening plane, includes a support region and a contact region between which the face can be arranged. A compensation device, having a first element and a second element movable relative to each other in an adjustment direction, is used to fasten the face The first and second elements are formed such that, between the contact region and the support region, a holding dimension, viewed perpendicularly to the adjustment direction, in which a zero-backlash fastening of the face is enabled between the contact region and the support region, can be modified by a movement of the first element relative to the second element in the adjustment direction. The support region is formed on the first element. Alternatively or additionally, the support region is formed on at least one protrusion formed on the first element.
