Sealing Device for Sliding Window Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing devices for sliding sashes and lift-slide sashes in windows and doors face issues with heat and sound insulation, security against unauthorized opening, and water tightness, particularly at the joint areas where the sash connects to the frame, leading to gaps and increased wear.
Innovation Solution
A sealing device comprising first and second sealing strips with molded parts that form a structural unit, providing a seamless seal around corners and ensuring continuous transition from horizontal to vertical frames, using materials like plastic and rubber for enhanced stability and weather resistance, with fastening screws positioned out of sight for security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If safety profiles are made of metal to prevent forced opening, then security against unauthorized opening is improved, but thermal and sound insulation deteriorate
Solution Approach 1:
The sealing device uses a composite structure combining a metal profile body (for security and structural integrity) with a covering profile body made of heat- and/or sound-insulating material (for thermal and acoustic insulation). This composite material approach allows both security and insulation requirements to be satisfied simultaneously.
Solution Approach 2:
Different parts of the safety profile have different properties: the profile body is made of metal for structural strength and security, while the covering profile body is made of insulating material for thermal and sound insulation. Each part is optimized for its specific function, allowing the overall system to meet multiple requirements.
2Object-affected harmful factors
If additional seals are used on security profiles to improve thermal and sound insulation, then insulation performance is improved, but wear due to sash movement increases
Solution Approach 1:
The sealing device is divided into two functional parts: the profile body that remains stationary on the frame and provides insulation, and the sealing strip that is attached to the movable sash and follows its movement. This segmentation ensures that the insulation structure does not experience wear from sash movement, while the sealing strip is designed to accommodate movement without compromising insulation performance.
3Reliability
If two-part arrangement of securing profiles is used to achieve security and insulation, then both security and insulation are improved, but installation space requirements increase
Solution Approach 1:
The profile body and covering profile body are designed to overlap and interlock, forming an integrated sealing device that combines security and insulation functions in a compact arrangement. The covering profile body at least partially covers the profile body, creating a space-efficient design that achieves both security and insulation without requiring excessive installation space.
4Ease of operation
If locking device is made accessible for easy opening, then ease of operation is improved, but security against unauthorized opening deteriorates
Solution Approach 1:
The covering profile body can be selectively removed or opened to provide access to the locking device when needed (for authorized opening), while normally remaining in place to protect the locking device from unauthorized access. This dynamic configuration allows the system to switch between security mode and operation mode as required.

AI summary
The invention relates to a sealing device (10) for a displaceable leaf as a sliding leaf (3) or a displaceable lift-and-slide leaf of a window or a door (1), consisting of sealing strips (11), (12) which are arranged in an impact region (9) between the sliding leaf (3) and a fixed panel (4) as well as between the sliding leaf (3) and a blind frame (2) for sealing and securing the intermediate spaces (9´) of a closed sliding leaf (3) of the window or a door (1), wherein in the impact region (9) a sealing strip (11) can be fastened with a contact surface to the leaf frame (5) of the sliding leaf (3), and wherein a sealing strip (12) can be vertically and horizontally fastened with a contact surface to a fixed panel frame (7) of the further fixed panel (4), wherein the sealing strips (11), (12) consisting of a profiled body (13) have first profiled sections (14) which mutually engage across or behind when the sliding leaf (3) is closed, and which form an operatively connected unit with the seals (15) arranged opposite thereof. On the free ends, the sealing strips (11), (12) have shaped parts (16), (17) which connect the vertical and horizontal sealing strips (11), (12) to form a structural unit, wherein the sealing strips (11), (12) and the shaped parts (16), (17) are guided with the seal (15) in a circulating manner at least around a corner of the sliding leaf (3) and in an angle of about 90° without interruption and seal the impact region (9) without a gap in a secure manner.
