Sliding Window Ventilation Lock with Horizontal Contact Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sliding windows and doors assemblies face challenges in maintaining airtightness and security, particularly when a window is slightly open for ventilation, as they lack a mechanism to prevent unauthorized access.
Innovation Solution
A windows and doors assembly with a horizontal contact function that includes a window frame, a handle, an engagement unit, and a horizontal moving device, allowing the window to come into contact with the windowsill or release contact based on handle movement, enabling ventilation while preventing the window from being freely open.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the window is kept slightly open for ventilation, then ventilation function is improved, but security and crime prevention deteriorate
Solution Approach 1:
The window assembly introduces a dynamic locking mechanism that can switch between different operational states (fully open, ventilable with lock, fully closed) based on user needs. The engagement unit and horizontal moving device create a dynamically adjustable security state that adapts to different ventilation requirements while maintaining security when needed.
Solution Approach 2:
The invention changes the operational parameters of the window by introducing a locked ventilable state where the window can be slightly open for airflow but restricted in movement. This parameter change allows the window to maintain both ventilation capability and security function simultaneously through the engagement unit that limits the window's opening degree.
2Ease of operation
If a conventional sliding window is used, then ease of operation is improved, but airtightness performance deteriorates due to gaps between windowsill and window
Solution Approach 1:
The horizontal moving device performs a preliminary horizontal movement of the window frame before the window is fully closed. This preliminary action brings the window into horizontal contact with the windowsill, eliminating gaps and ensuring airtightness before the closing operation is completed.
Solution Approach 2:
The engagement unit acts as an intermediary mechanism between the horizontal moving device and the window closing operation. It coordinates the horizontal movement and vertical closing actions to ensure the window achieves proper contact with the windowsill for airtightness while maintaining ease of operation through the integrated handle mechanism.
3Reliability
If the window is completely closed for security, then security function is improved, but ventilation function deteriorates
Solution Approach 1:
The invention provides a dynamic solution that allows the window to operate in multiple states including a locked ventilable state. In this state, the engagement unit engages with the engagement guide to prevent full opening while allowing slight movement for ventilation, thus maintaining both security and ventilation functions simultaneously.
Solution Approach 2:
The window operation is segmented into distinct functional states: fully closed, locked ventilable (slightly open), and fully open. The engagement unit and horizontal moving device enable transitions between these segmented states, allowing users to select the appropriate level of security and ventilation based on needs.

AI summary
The present disclosure relates to a windows and doors assembly having a ventilation function and a horizontal contact function, and more particularly to a horizontal contact windows and doors assembly for crime prevention and security functions by preventing a window from being open even when the window is slightly open and it is possible to ventilate with the outside air. To achieve the objective of the present disclosure, the windows and doors assembly having a ventilation function and a horizontal contact function includes a window frame, and a windowsill in which the window frame is slidably installed, a handle rotatably installed on the window frame, an engagement unit provided on a lateral surface of the window frame, linked to movement of the handle, and moved in upward and downward directions, an engagement guide provided on the windowsill to face the engagement unit and configured to catch or not catch the engagement unit depending on a position of the engagement unit, and a horizontal moving device provided on at least one of a top surface or a bottom surface of the window frame, linked to the handle, and configured to make the window frame horizontally come into contact with the windowsill or to release horizontal contact depending on movement of the handle, and in this case, when a contact state of the window with respect to the windowsill by the horizontal contact device is released while a catching operation between the engagement unit and the engagement guide is performed, it is possible to ventilate through a gap between the window and the windowsill, the window is restrictly moved to form the gap, and the window is prevented from being freely open.
