A door including a barrier-free sill is disclosed. The sill preferably has recesses on its upper side, the width of the recesses being less than 50 mm and/or the depth of the recesses being less than 3 mm. A leaf can penetrate the upper side in a leaf recess. The leaf may fall below the vertically uppermost dimension of a running rail. Using at least one projection of a carriage that extends into a guide groove, it is possible to reliably seal or transversely support the leaf in the event of wind pressure or a break-in attempt. The projection preferably extends further down than a running roller of the carriage. This enables the design of a particularly stable and yet barrier-free door.

A window regulator assembly of a motor vehicle includes a guide rail on which a slide shoe is longitudinally movably mounted. The slide shoe has a main bracket which is mounted on the guide rail, and has a clamping arrangement. The clamping arrangement includes a clamping bracket connected to the main bracket and includes a pressure plate disposed parallel to the clamping bracket. A clamping component is clamped between the clamping bracket and the pressure plate. The clamping component holds a window pane. The clamping component has a holding surface which is disposed parallel to the pressure plate and a spacing between the holding surface and the clamping bracket is adjustable. A slide shoe of a window regulator assembly is also provided.

A method for producing a carrier element for a window lifting device in which adjustment of a glass is performed by means of a traction means, the carrier element being displaceable along a guide rail of the window lifting device and being connected to the traction means, is provided. The completed carrier element has at least two interconnected bodies which are produced from dissimilar materials having dissimilar melting points, and the carrier element having the at least two bodies is produced by a multicomponent injection-molding method. In the production of the carrier element by the multicomponent injection-molding method a body from a material melting at a lower temperature is molded before a body from a material melting at a higher temperature, and the body from the material melting at a higher temperature is molded to the body from the material melting at a lower temperature.

Movable partitions may include leading end assemblies comprising an articulated leading member. The articulated leading member may be coupled to a support trolley, and at least one coupling between the articulated leading member and the trolley enables the articulated leading member to move relative to the support trolley. Methods of operating a movable partition include displacing a portion of a leading end assembly to align a majority of at least one surface of the leading end assembly with a portion of an adjacent structure.

Apparatuses, such as shower door frame kits, for installing sliding shower door assemblies are provided. The apparatuses enable secure and convenient installation of the sliding shower door assemblies, while keeping water that may escape a shower area to a minimum. The apparatuses of the present disclosure also provide for efficient installation of the sliding shower door assemblies that can be completed with a single tool and/or in a single step. The apparatuses for installing sliding shower door assemblies may include one or more of a shower door header, a wall jamb, a shower header retainer, a shower door catcher, a roller assembly, a corner bracket, and a shower threshold.
