Definitions

• the invention relates to a sliding door arrangement with a fixed frame and a sliding leaf movable relative thereto according to the preamble of claim 1. Furthermore, the invention relates to a method for assembling a sliding door arrangement according to the independent claim.
• such a sash In order to be installed in a fixed frame, such a sash must first be connected to the guide on the upper cross member of the frame and to the guide rail there. It can then be placed freely on the guide rail using the bogies, tilting downwards (first insert it into the guide rail at the top, then place it onto the guide rail at the bottom). This is particularly time-consuming and cumbersome with heavy sashes. For example, due to space constraints, the locking mechanism must be installed before the sash is inserted. This not only complicates installation, but also makes subsequent disassembly, e.g., for maintenance or repair, difficult and time-consuming. Due to the complex handling and the heavy sash weight, there is a significant risk of injury for fitters during installation and disassembly of such sashes.
• the invention is based on the object of enabling simple and safe installation in a sliding door arrangement.
• the sliding door arrangement comprises a fixed frame and a relative to the fixed frame between at least one Sliding sash that can be moved in an open position and a closed position along a sliding direction.
• the sliding door assembly further comprises a locking device for locking the sliding sash to a frame cross member of the fixed frame that is located upper relative to the direction of gravity g.
• the locking device comprises a locking bar guided on the sliding sash with a locking head (which can be coupled to the locking bar or is coupled to it and) facing the upper frame cross member.
• the locking device can be formed predominantly on the sash side or entirely on the sash side.
• the sliding door assembly also includes a guide device for guiding the sliding sash in a guide rail attached to the upper frame cross member.
• the guide device can penetrate the guide rail with a guide section (e.g., a U-shaped cross-section open at the bottom).
• a guide section e.g., a U-shaped cross-section open at the bottom.
• the locking head comprises a lower headpiece and an upper headpiece.
• the headpieces in turn, have corresponding profile features (connecting contours) by means of which the headpieces can be connected to one another in a form-fitting manner such that (when connected) the upper headpiece continues the lower headpiece to form the locking head.
• the lower headpiece is connected, preferably directly, to the locking bar.
• the upper head piece is located in an interior space of the guide mechanism and is slidably guided in a locking channel extending from the interior space and opening at the top of the guide mechanism.
• the guide mechanism is open to the interior space of the guide mechanism on one mounting side (the side of the guide mechanism facing the sliding sash when installed).
• the guide device can be placed (using a mounting movement) with its mounting side facing the front of the sliding sash and secured to the sliding sash, e.g., by screwing.
• the mounting movement can be designed such that the guide device is moved toward the front of the sliding sash essentially orthogonally (at an angle of 90° ⁇ 5°) to the front of the sliding sash (parallel to the sliding direction).
• the profile features of the head pieces face each other and are aligned with each other, so that the head pieces can be connected to each other or are connected to each other (pairing of the profile features) when the guide device is placed on the sliding sash (front-side).
• the locking head is divided into a lower headpiece and a separate upper headpiece, which are coupled together by their profile features when the guide device is placed on the sliding sash.
• the lower headpiece is connected to the locking bar guided on the sliding sash, and the upper headpiece is slidably mounted in the guide device.
• the headpieces are connected to each other, thus forming the locking head, which is connected to the locking bar.
• the multi-part locking head eliminates the need to first insert the sliding sash with its guide mechanism into the guide rail at the top, then allow the sliding sash to pivot freely and place it on the track at the bottom. Instead, the sash can now be securely placed (at the bottom) on the track in a tilted position and then pivoted (at the top) towards the fixed frame.
• the guide mechanism By placing the guide mechanism on the front of the sliding sash, the locking bar is completed by coupling the head pieces. Since the guide mechanism engages in the guide rail on the upper frame cross member (guide section) and is attached to the sliding sash, the sliding sash is also guided on the upper frame cross member.
• the sliding door arrangement can be designed such that the fixed frame has two fixed panels (spaced apart along the sliding direction), between which the sliding sash is arranged when the sliding sash is in the closed position (so-called "Scheme G1").
• the sliding sash can be displaced along the sliding direction in front of at least one of the two fixed panels. It is also conceivable for the sliding sash to be displaced in front of both fixed panels. This allows for several (fully) open positions (sliding sash open position in front of the first fixed panel and sliding sash open position in front of the first fixed panel). Locking is provided at the upper frame cross member and/or at the lower frame cross member or at the floor.
• the sliding sash can be guided by a guide mechanism on the lower frame cross member or on the floor.
