Building Lock Relocation to Frame for Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional building locking devices with electric motor-operated locks on adjustable wings require complex electrical connections and cable transitions, compromising the tightness and aesthetics of the wing, and often necessitate additional openings for lock cylinders, which can impair the wing's integrity.
Innovation Solution
The lock is relocated from the adjustable wing to the frame, allowing for a simpler electrical connection and improved tightness by eliminating cable transitions, with the handle on the wing acting on the frame-based lock to unlock the wing, either manually or via an electric motor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lock is arranged on the adjustable sash, then the locking function is achieved, but the electrical connection becomes complex and the sealing is compromised
Solution Approach 1:
The patent inverts the conventional arrangement by placing the lock on the frame instead of on the adjustable sash. This reversal eliminates the need for electrical connections to the movable sash, as the lock remains stationary on the frame while the locking element on the sash engages with it. The handle on the sash acts on the lock or locking element to unlock, maintaining functionality while simplifying electrical connections.
2Reliability
If the lock is arranged on the adjustable sash, then the locking function is achieved, but the tightness against moisture and dirt is compromised
Solution Approach 1:
By inverting the lock arrangement to be on the frame rather than the sash, the patent eliminates cable transitions and openings on the sash that would compromise sealing. The stationary lock on the frame does not require penetrations through the movable sash, thereby maintaining the sash's tightness against moisture and dirt while achieving the same locking function.
3Ease of operation
If a locking cylinder is provided on the adjustable sash, then manual key operation is enabled, but additional openings are created that impair the wing's integrity
Solution Approach 1:
The patent moves the locking cylinder from the adjustable sash to the frame, reversing the conventional arrangement. This allows manual key operation to be enabled while avoiding additional openings in the sash that would impair its integrity and tightness. The locking cylinder on the frame can operate the lock without compromising the sash structure.

AI summary
A building closing device for closing a building opening comprises a frame that at least partially defines the building opening, an adjustable sash that is adjustable to the frame for opening or closing the building opening, and a lock that includes an electromechanical drive and at least one electromechanically adjustable locking device. In a locked position, the lock engages the adjustable sash with the frame to close the building opening and can be unlocked to adjust the sash relative to the frame. A manually operated handle on the adjustable sash is used to operate the lock.The lock (6) is arranged on a frame section (30) of the frame (3) and, in the locked position, engages in a locking engagement with a locking element (24) arranged on the adjustable sash (2). The handle (23) arranged on the adjustable sash (2) is designed to act upon manual operation of the handle (23) to unlock either the lock (6) arranged on the frame (3) or the locking element (24) arranged on the adjustable sash (2), thereby releasing the locking engagement of the locking element (24) with the lock (6). In this way, a locking device for a building is provided in which the arrangement of a lock can be easily improved in such a way that an electrical connection of the lock is simplified and any impairment, for example, of the tightness of the adjustable sash by the lock is at least reduced.
