Description

Technical Field

[0001] This utility model relates to the technical field of sliding window track devices, and in particular to an adjustable angle sliding window track device. Background Technology

[0002] In building envelope systems, windows play a crucial role, their performance directly affecting various aspects of a building, including lighting, ventilation, insulation, and indoor comfort. Sliding windows, as one of the most widely used window types, are favored by architects and users due to their simple structure, convenient operation, and the advantage of not occupying additional indoor or outdoor space. However, traditional sliding window track devices have revealed many insurmountable limitations in long-term practical application. Meanwhile, with the improvement of people's living standards, the demand for personalized and intelligent building spaces is increasing. Users expect to be able to flexibly control the opening status of windows according to their real-time needs. In high-rise residential buildings, to ensure children's safety, parents may want windows with controllable opening angles to prevent accidents caused by excessively large openings. In office spaces, people at different workstations have different needs for lighting and ventilation; adjustable-angle windows can meet everyone's individual needs and improve the comfort of the working environment. Furthermore, the rise of smart home concepts has led to greater expectations for intelligent window control, making adjustable-angle track devices, as the basic hardware for realizing intelligent window control, increasingly important.

[0003] Currently, most sliding window track systems on the market consist of a track body and an angle adjustment mechanism. Traditional sliding window tracks are mostly designed with a fixed angle, which limits the window's opening trajectory to only one direction. In practical use, this fixed mode cannot meet the needs of complex and ever-changing environments. From a ventilation perspective, wind direction and force vary significantly in different seasons and at different times. In the hot summer, people often expect windows to open at a specific angle to introduce more natural wind, achieve efficient indoor air convection, and achieve the best cooling effect. However, fixed-angle tracks make it difficult to precisely adjust the window to the ideal ventilation angle, often resulting in poor ventilation and persistent stuffiness indoors. In spring and autumn, when there is wind and the wind direction is changeable, fixed-angle windows cannot flexibly cope with changes in wind direction, making it difficult to guarantee effective ventilation. In terms of lighting, the solar altitude angle varies at different times. With the changing seasons and time of day, fixed-angle sliding windows are difficult to adjust according to the angle of light incidence, failing to fully utilize natural light at different times. This results in insufficient lighting and glare in some indoor areas, affecting the indoor visual environment and comfort. Furthermore, during construction, it's difficult to achieve perfect installation precision between the wall and window frame. Due to shrinkage of building materials and construction errors, unevenness and tilting of the wall and window frame are common. Traditional fixed-angle sliding window tracks require stringent installation precision; any deviation in the wall or window frame will severely hinder the window's sliding on the track, potentially causing jamming, wobbling, or even failure to close completely. This not only affects the window's normal function but also accelerates wear on the track and rollers, significantly shortening the window's lifespan and increasing future maintenance costs.
