Angled Seal-Slider Ventilator for Lateral Window-Sash Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window and door ventilation elements are difficult to open and close, especially when installed on the upper side of a window or door, as they require perpendicular movement and can obstruct the tilting or pivoting of the window or door, and often lack adjustable ventilation control.
Innovation Solution
The ventilation element features a base plate with side walls and an upper guide plate forming a housing, allowing for oblique sideways movement of the sealing slide, facilitated by a handle element and pull cord connection, enabling lateral force action to move the sealing slide from open to closed positions without needing direct access to the top of the window or door.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sealing slide is moved perpendicularly to the window sash using a pulling or pushing movement, then the air flow path can be closed, but the operation becomes difficult when the ventilation element is arranged on the upper side of a window sash and may not be easily accessible
Solution Approach 1:
The sealing slide is moved from a perpendicular direction (relative to the window sash) to a lateral direction (parallel to the window sash). This dimensional change allows the ventilation element to be operated from the side even when installed on the upper side of the window, solving the accessibility problem while maintaining the closing function.
2Adaptability or versatility
If the ventilation element is attached on the upper transverse area of the window or door, then it can be installed without obstructing window or door mobility, but it may not be easily accessible for operation
Solution Approach 1:
By changing the movement direction from perpendicular to lateral, the patent enables operation of ventilation elements installed in hard-to-reach positions (upper transverse area) by accessing them from the side, thus maintaining installation flexibility while improving operational accessibility.
3Productivity
If multiple ventilation elements are provided on a window frame to meet required ventilation standards, then the ventilation volume can be increased, but the device complexity and number of components increase
Solution Approach 1:
The patent creates a universal ventilation element design that can be installed in multiple positions (upper transverse area, lower transverse area, side areas) and operated from the side. This multi-position capability allows a single type of element to be used throughout the window frame, enabling flexible configuration to meet various ventilation requirements without increasing device complexity.

AI summary
In a window or door ventilation element (1) with at least one ventilation element influencing a ventilation volume flow in the window or door rebate (22), which comprises a sealing slide (11) with which an air flow path (7) formed in the sealing area of the sash overlap seal can be closed, the Window or door ventilation element (1) has a base plate (10) with at least two delimiting webs (3) protruding on one of its long sides, which extend into the sealing area of the sash overlap seal or window rebate seal (6) between the window or door sash (2nd ) and window or door frame (4) can be positioned in an engaging manner and which form one or more slit-shaped opening(s) (13) between them, a solution is to be created which enables a simplified and improved opening and closing of a generic window or door ventilation element . This is achieved in that the base plate (10) has side walls (14a, 14b, 14c) on its side edges that do not have the guide webs (3) and, in cooperation with the upper guide plate (12), a housing that is at least essentially closed on three sides with a a gripping element (16) of the sealing slide (11) and that the slot openings (19) are arranged at an angle to the longitudinal axis and the transverse axis of the base plate (10) and the sealing slide (11) in such a way that by means of a lateral movement of the handle element (16), the sealing slide (11) can be moved in an oblique lateral forward movement from its maximum open position to its closed position.
