Sliding Window Cover Members with Rollers for Draft Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional windows allow drafts, rain, dust, and noise to enter through gaps between the window casing and frames, compromising insulation and soundproofing when closed.
Innovation Solution
A horizontally sliding window design featuring square frame-shaped window casings with transverse and longitudinal frames, movable frames, and cover members with rollers to ensure a tight seal by covering both indoor and outdoor sides, with the second rail part being taller than the first and including hook pieces and guide protrusions for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional windows use simple guide grooves and sliding frames, then the window structure is simple and easy to manufacture, but gaps are formed between the window casing and window frames allowing wind and noise to enter
Solution Approach 1:
The window system is divided into multiple components: window casing, first window with first movable frame, and second window with second movable frame. Each component has specific functions, with movable frames providing sealing coverage that prevents wind and noise intrusion while maintaining manufacturing simplicity through modular assembly
Solution Approach 2:
The sealing mechanism transitions from linear guide grooves to two-dimensional cover members that extend across both indoor and outdoor sides of the window casing. This dimensional expansion creates comprehensive sealing surfaces that block wind and noise from entering through gaps
2Ease of operation
If the window frame is placed in the window casing without secure engagement, then the window can be easily installed and removed, but the window becomes unstable and gaps form allowing drafts and rain to enter
Solution Approach 1:
Hook pieces are pre-formed on the window casing and cover members are pre-shaped with engagement features. These preliminary structural preparations enable reliable coupling when the window is installed, ensuring stable engagement that prevents drafts and rain intrusion while maintaining ease of installation through straightforward coupling actions
Solution Approach 2:
Movable frames serve as intermediary components between the window casing and the windows. These intermediaries provide both sealing functionality and engagement mechanisms, mediating the connection between fixed and movable elements to ensure stability while allowing easy installation and removal
3Object-affected harmful factors
If cover members extend from both sides of the movable frame, then the sealing function is improved to block drafts and rain, but the device complexity increases
Solution Approach 1:
The cover members perform multiple functions simultaneously: they seal the gap between the window casing and window frames to block drafts and rain, provides structural support for the movable frame, and enable engagement with the window casing through integrated coupling features. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity

Function Achieved in This Case
The design effectively blocks drafts, rain, dust, and noise while maintaining a stable window position, enhancing insulation and soundproofing by ensuring the window is firmly coupled to the casing and preventing separation.
Implementation Method 1
rollers rotatably coupled between the first and second cover members so as to operate in contact with the first rail part

AI summary
The present invention relates to a horizontally sliding window which can block a draft, rainwater, dust, and noise from being introduced through a gap between a window casing and a window while the window is closed, thereby improving indoor heat insulating and soundproof functions of the window. A horizontally sliding window according to an embodiment of the present invention comprises: a square frame-shaped window casing having a transverse frame and a longitudinal frame assembled therein; a window disposed on an inner side of the window casing; and moving frames which are respectively interposed between the transverse frame and an upper end portion of the window and between the transverse frame and a lower end portion of the window, each of which includes a first and a second cover member extending from opposite sides thereof to cover an indoor and an outdoor side of the transverse frame, respectively, and has a roller rotatably coupled between the first cover member and the second cover member so as to operate in contact with the transverse frame.
